Abstract Objective To explore the correlation between uteroglobulin-related protein 1 ( UGRP1) and primary hypothyroidism. Methods Ninety-six patients with primary hypothyroidism were selected , including 66 patients with positive thyroid peroxidase antibodies (TPOAb) or anti-thyroglobulin antibodies (ATG) as the antibody-posi- tive group , 30 patients with negative thyroid autoantibodies as the antibody-negative group , and 96 healthy people as the control group . The general clinical data , thyroid-related indicators and serum UGRP1 levels were compared among these three groups . Human thyroid normal cells (NTHY-ORI 3-1) were transfected with plasmids in vitro , thus establishing the control group as well as the UGRP1 group . Enzyme linked immunosorbent assay (ELISA) was used to detect and compare the T4 level in the cell culture supernatant. Results The differences in thyroid stimu- lating hormone (TSH) , TPOAb and ATG among the three groups were statistically significant ( P < 0. 05) . The serum UGRP1 levels in the antibody-positive (303 . 97 ±156. 00) pg/m Land antibody-negative groups (352. 13 ± 188. 37)pg/m L were higher than those in the control group(237 . 54 ±137 . 20)pg/m L，and the differences between the groups were statistically significant ( P = 0. 005) . Meanwhile , there was no statistically significant difference between the antibody-positive and antibody-negative groups . Multi-factor Logistic regression analysis showed that UGRP1 was the risk factor for the occurrence of primary hypothyroidism (OR = 1 . 004 , 95% CI:1 . 001 - 1 . 007 , P = 0. 007) . The difference between the control group and UGRP1 group in T4 concentration secreted by human thyroid normal cells was not statistically significant. Conclusion Serum UGRP1 levels increase in patients with primary hypothyroidism , and the high expression of UGRP1 may have no direct relation to the function of thyroid cells secre- ting T4 .

Abstract Objective To investigate the value of decreased carbohydrate antigen 19-9 (CA19-9) kinetics in pre- dicting short-term outcomes and determining prognosis among advanced biliary or pancreatic cancer patients receiv- ing first- or second-line therapy in the real world . Methods Eighty-nine patients were retrospectively collected with advanced biliary or pancreatic cancer , especially on the CA19-9 dynamics and decline rates at different time points . This study evaluated the association of CA19-9 changes with clinicopathological features , short-term re- sponse to antitumor therapy , and survival outcomes . Results The enrolled patients recorded baseline CA19-9 lev- els ranging from 1 . 20 to 65 706. 40 U/ml , with a median of 303 . 11 U/ml . There was no statistical correlation be- tween baseline CA19-9 levels and gender , age , body mass index , primary tumor site , hepatic metastases , pulmo- nary metastases , lymph node metastases , peritoneal metastases , performance status , treatment lines , and combina- tions of drug types . Baseline CA19-9 levels were not associated with systemic immunoinflammatory index , prognos- tic nutritional index , and total bilirubin . A 25% or 50% decrease in CA19-9 after 2 - 3 therapy courses indicated short-term efficacy in reaching tumor objective remission or disease control . Both combinations of multiple drug types and a 25% decline in CA19-9 after one course of treatment were independent prognostic factors that affected the longer progression-free survival of patients receiving first or second line of treatment. Conclusion Decreased CA19-9 kinetics has specific values in predicting the efficacy and prognosis of advanced biliary or pancreatic cancer.

Abstract Objective To evaluate the clinical value of combining low-dose energy spectrum CT with virtual un-en- hanced (VUE) scanning and deep-learning image reconstruction (DLIR) in aortic CT angiography (CTA) . Meth- ods In a prospective study , 94 patients scheduled for aortic CTA were randomized into two groups : a low-dose en- ergy spectrum group and a standard 100 kVp enhancement group , with 47 patients in each . All patients initially underwent a true un-enhanced (TUE) scan at 120 kVp using adaptive statistical iterative reconstruction-V (ASIR- V) at 40% for image reconstruction . The low-dose group received enhanced scans using gemstone spectral imaging (GSI) mode with DLIR-H , producing 60 keV virtual monoenergetic images (VMIs) and VUE images . The stand- ard group was scanned at 100 kVp , with images reconstructed using ASIR-V at 50% . Parameters were measured including CT values , noise (SD) , signal-to-noise ratio (SNR) , and contrast-to-noise ratio (CNR) for key vascu- lar and muscular areas , alongside the effective radiation dose (ED) . Two radiologists evaluated the image quality using a 5-point scale . Results The low-dose group exhibited significantly higher SNR and CNR values in the as- cending aorta , descending aorta , abdominal aorta , and common iliac artery compared to the standard group (P < 0. 05) , with comparable subjective quality scores . The VUE images also demonstrated superior SNR values in the abdominal aorta , common iliac artery , and psoas major muscle , and CNR value in the ascending aorta compared to TUE images , with similar subjective quality. Importantly , the ED in the low-dose group was about 40% lower than that of the standard group . Conclusion Low-dose energy spectrum CT with DLIR in aortic CTA can significantly enhance SNR and CNR , while approximating the image quality of traditional TUE scans , thereby substantially re- ducing radiation exposure .

Abstract Objective To assess the epidemiological , drug resistance , and their relative risk and prevalence for yielding clinical diseases of Streptococcus mitis group (SMG) bloodstream infections in recent years . Methods A total of 50 blood culture specimens were collected from patients with SMG bloodstream infection . These SMG iso- lates were identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry ( MALDI-TOF MS) . The susceptibility to antibiotics was tested by minimal inhibitory concentrations and Kirby-Bauer (K-B) disk diffusion methods . The data were comprehensively analyzed by statistical software combined with clinical data. Re- sults Five strains were identified in SMG bloodstream infection by mass spectrometry , namely Streptococcus oralis/ mitis (S. oralis/mitis) , Streptococcus pneumonia (S. pneumonia) , Streptococcus gordonii (S. gordonii) , Streptococ– cus sanguinis (S. sanguinis) , and Streptococcus parasanguinis. These SMG showed high resistance to erythromycin and clindamycin , but low resistance to penicillin , ampicillin and ceftriaxone . Reduced hemoglobin and albumin , elevated C-reactive protein and procalcitonin were the common hematological changes in patients with SMG blood- stream infections . In SMG bacteremia , S. gordonii , S. sanguinis and S. orals/mitis were the leading group causing infective endocarditis . Patients with myocardial disease factor were more likely to cause infective endocarditis by S. gordonii and S. sanguinis , compared with S. orals/mitis. S. oralis/mitis bacteremia more occurred in patients with renal transplants progressing to pulmonary infection . Conclusion In this area , β- lactam antibiotics are the best choice for treating SMG. SMG species with closely related phylogenetically show different prevalence and risk of clinical disease in bloodstream infection patients . Early prevention and diagnosis of bacteremia caused by SMG are necessary for clinical diagnosis , treatment and effective control of infectious diseases progression .

SPSS 23 . 0 was used for statistical analyses . Results The prevalence of suicidal ideation was 21 . 7% in patients with schizophrenia. Logistic stepwise regression analyses showed that Cal- gary depression scale (CDSS) total score (OR = 1 . 490 , 95% CI = 1 . 287 - 1 . 724 , P < 0. 001) , insomnia severity index scale (ISI) total score (OR = 1 . 096 , 95% CI = 1 . 011 - 1 . 187 , P = 0. 025) , modified overt aggression scale (MOAS) total score (OR = 1 . 111 , 95% CI = 1 . 016 - 1 . 215 , P = 0. 021) , MLR(Ln) (OR = 15 . 123 , 95% CI = 3 . 868 - 59. 125 , P < 0. 001) , and triiodothyronine ( T3) ( OR = 0. 037 , 95% CI = 0. 003 - 0. 388 , P = 0. 006) were the independent influences of suicidal ideation . Additionally , receiver operating characteristic (ROC) curve analyses revealed that the five-item combination of CDSS total score , ISI total score , MOAS total score , MLR (Ln) , and T3 (AUC = 0. 908 , 95% CI = 0. 867 - 0. 949 , P < 0. 001) had better ability to identify suicidal idea- tion . Conclusion The risk of suicidal ideation is relatively high in patients with schizophrenia , and there may be stronger associations between suicidal ideation and depression , insomnia , aggression , MLR , and T3 .

Abstract Objective To explore the central role of interleukin (IL)-25 in allergy of eosinophil asthma. Methods Forty 4 - 5 week-old C57BL/6 mice were used in this study ( n = 10) . Mice were randomly divided into 4 groups : WT + shRNA NT group , WT + HDM group , IL-25 shRNA + IL-25 group , and IL-25 shRNA + IL-25 + HDM group . According to each group ′s treatment requirement , mice were treated with house dust mite and/or IL- 25 by intranasal infusion . HE staining and PAS staining were used for lung tissue section staining and pathological analysis . The levels of type 2 cytokines in bronchoalveolar lavage fluid (BALF) were determined by ELISA . Flow cytometry (FCM) was used to determine the number of type 2 helper T (Th2) cells , the group 2 innate lymphoid cells (ILC2) and eosinophils in lung tissues . Mice were treated with FITC-labeled DQ-ovalbumin (DQ-OVA) by intranasal infusion to determine the antigen presentation ability of eosinophils infiltrated in the lungs . Results HE staining and PAS staining results showed that , compared with WT + shRNA NT group , a large amount of mucus and a large number of eosinophil infiltration were found in the lungs , and subcutaneous thickening of inflammatory air- way were observed in the pulmonary vessels , alveolar ducts and the whole alveoli in IL-25 shRNA + IL-25 + HDM group . In the IL-25 shRNA + IL-25 group , only a small amount of mucus and a small amount of eosinophil infiltra- tion were found in the lungs , and a small amount of subcutaneous thickening of inflammatory airway were observed in pulmonary vessels , alveolar ducts and the whole alveoli . There was no significant difference in WT + HDM group . Compared with WT + shRNA NT group , the levels of IL-25 , IL-4 , IL-5 , IL-13 , IL-33 and interferon-γ (IFN-γ) in BALF significantly increased; the levels of infiltrated Th2 , ILC2 and eosinophils in the lung signifi- cantly increased; the fluorescence levels of FITC-labeled DQ-OVA in eosinophils infiltrated in lungs significantly increased in IL-25 shRNA + IL-25 + HDM group (P < 0. 05) . IL-25 shRNA + IL-25 group mice also showed an in- crease in the above measurements , but the amplitude were limited (P < 0. 05) . WT + HDM group had no signifi- cant difference . Conclusion IL-25 plays an essential role in the allergy and eosinophil antigen presentation processes in eosinophil asthma mice .

Abstract Objective To investigate the molecular mechanisms and pathways of action of total flavonoids of Draco- cephalum moldavica L. (TFDM) in treating vascular cognitive impairment ( VCI) based on network pharmacology and in vivo animal experiments . Methods The swiss target prediction database , literature , and PubChem were used to screen the active components and action targets of TFDM . The online mendelian inheritance in man ( OMIM) and GeneCards databases were utilized to screen for possible VCI targets . Venny software was used to ob- tain the intersection target of TFDM and VCI . The search tool for recurring instances of neighbouring genes (String) database and Cytoscape software was used to construct the PPI network . The database for annotation , vi- sualization and integrated discovery (DAVID) database was utilized to screen for the kyoto encyclopedia of genes and genomes (KEGG) pathway and gene ontology (GO) enrichment analyses to explore the molecular mechanism and signaling pathway of TFDM for VCI . 24 rats were divided into Sham , Model , Donepezil , and TFDM groups . Except for the Sham group , the VCI model was created using modified bilateral common carotid artery ligation . Af- ter continuous gavage for 21 days , the Morris water maze test was used to evaluate the spatial learning and memory ability of rats . Hematoxy-lineosin (HE) staining was used to observe the pathological changes in the hippocampal CA1 and cortex region of the animals and immunohistochemistry detection of zonula occludens-1(ZO-1) content in the brains of the rats . Western blot was used to detect nuclear factor kappa-B p65 (NF-κB p65) and tumor necro- sis factor-α(TNF-α) in rat brains . Results A total of 39 active ingredients of TFDM were screened , 209 corre- sponding targets , 10 417 gene targets of VCI , and 193 intersecting targets . According to the results of the GO en- richment of function analysis , TFDM could improve the response of reactive oxygen species and metabolic processes of reactive oxygen species , etc . KEGG pathway enrichment analysis suggested that TFDM might regulate TNF , IL- 17 signing pathway , etc . The results of animal experiments showed that TFDM improved learning and memory while reduced pathological damage in the brains of VCI rats . In addition , TFDM upregulated the positive expression of ZO-1 and downregulated the protein levels of TNF-αand NF-κB p65 ( P < 0. 05 ) . Conclusion TFDM can improve the cognitive function of VCI through multi-components and multi-targets , and its key mechanism may be related to inhibiting TNF-α/NF-κB p65 signaling pathway , reducing neuroinflammation , and improvement of blood- brain barrier permeability.

Abstract Objective To explore the characteristic of obesity in adolescents with major depressive disorder and its relationship with inflammatory cytokines . Methods One hundred and forty adolescents with major depressive disor- der were enrolled . According to the classification standard of body mass index (BMI) for adolescents in China , the patients were classified into underweight group , normal group , overweight group and obese group . The center for epidemiologic studies depression scale (CES-D) was used to evaluate symptoms of depression in patients , and ul- trasensitive multiplex electrochemiluminescence detection technology was used to measure the levels of plasma in- flammatory cytokines including interleukin(IL)-6 , IL-17A , IL-1β, IL-6 , IL-8 and tumour necrosis factor(TNF) -α. One-way ANOVA or Kruskal-Wallis H test and chi-square test were used for comparison between groups . Binary Logistic regression was used to analyze the influencing factors of obesity in adolescent patients with major depressive disorder. Results Among the 140 adolescent patients with major depressive disorder , wasting were 9. 3% ( 13/ 140) , overweight were 17. 9% (25/140) and obesity were 6. 4% (9/140) respectively . There were statistically significant differences in gender ( χ2 = 8. 301 , P < 0. 05 ) and inflammatory cytokines IL-6 ( H = 16. 217 , P < 0. 01) , IL-8 (H = 10. 926 , P < 0. 05) and TNF-α(H = 7 . 879 , P < 0. 05) among the four groups . Analysis of co- variance showed that the difference in levels of the inflammatory cytokine IL-6 (F = 4. 486 , P < 0. 01) remained statistically significant after controlling for age , gender and antidepressant use . The results of multiple comparisons showed that compared with the wasting group , the plasma IL-6 (Z = - 3 . 843 , P Bonferroni calibrate < 0. 01) were higher in the obese group;compared with the normal group , the obesity rate of males was higher than that of females ( χ2 = 8 . 812 , P Bonferroni calibrate < 0. 01) , and the level of IL-6 in the obese group (Z = - 3 . 023 , P Bonferroni calibrate < 0. 05) was higher. Binary Logistic regression analysis showed that plasma IL-6 (OR = 2. 500 , P < 0. 01) and gender (OR = 11 . 292 , P < 0. 01) were independent influencing factors for obesity in patients with adolescent depressive disor- ders . Conclusion There are gender differences in obesity rates in adolescents with depressive disorders , and obe- sity is associated with elevated levels of inflammatory cytokines .

Abstract Objective To explore the molecular characteristics of four CAMP negative Streptococcus agalactiae (S. agalactiae) in whole genome sequencing. Methods The identification of suspicious bacterial strains was conduc- ted using matrix-assisted laser desorption ionization time-of-flight mass spectrometry ( MALDI-TOF MS) . For the strains confirmed as S. agalactiae through identification , further CAMP experiments were conducted . For CAMP negative strains , whole genome sequencing was performed using MGI DNBSEQ-T7 and MinION Flow Cell sequen- cing platforms . Subsequently , multi-locus sequence typing ( MLST) , virulence genes and resistance genes of the strains were compared and analyzed using various databases . Phoenix M50 fully automatic drug sensitivity analyzer was employed to determine the sensitivity of the bacterial strains to commonly used antibiotics . Results Four CAMP-negative S. agalactiae strains were included . Whole-genome sequencing analysis revealed that all four CAMP-negative S. agalactiae strains belonged to the ST862 type . These strains harbored 22 virulence genes associ- ated with capsular polysaccharides , β-hemolysin , and hyaluronidase , as well as seven resistance genes linked to macrolides , lincosamides , polypeptides , and aminoglycosides . Antimicrobial susceptibility testing revealed that CAMP-negative S. agalactiae was susceptible to penicillin G , cefepime , cefotaxime , and vancomycin . However , three strains exhibited resistance to erythromycin , and one strain demonstrated resistance to clindamycin . Conclu- sion Four CAMP negative S. agalactiae of the ST862 type possess multiple virulence and drug resistance genes , showing high resistance to erythromycin , warranting clinical attention .

Abstract Objective To investigate the relationship between the risk occurrence of rectal cancer and the single nucleotide polymorphisms (SNP) of zinc finger protein 6(ZBED6) , and to provide the experimental basis for early diagnosis and treatment of rectal cancer. Methods Polymerase chain reaction-restriction fragment length polymor- phism (PCR-RFLP) technology was used to genotype the ZBED6 gene in 109 randomly selected rectal cancer pa- tients and 110 unrelated healthy controls . To evaluate the relationship between alleles , genotypes and the risk of rectal cancer , unconditional Logistic regression analysis was used to OR and 95% CI. Results The SNP rs7552670 of ZBED6 had significant correlation with the risk of rectal cancer. Compared with the population carrying the TT genotype , those carrying the TC genotype had a 2. 653 fold increased risk of rectal cancer (TT vs TC : OR = 2. 635 , 95% CI = 1 . 501 - 4. 690) . Other SNPs had no significant correlation with the risk of rectal cancer. Conclusion There is an interaction between the polymorphisms of ZBED6(rs7552670) and rectal cancer. The population car- ried ZBED6 rs7552670 TC genotype had an growing risk of rectal cancer.

Abstract Objective To investigate associations of suicidal ideation with clinical features , inflammatory markers ,and thyroid hormones in patients with schizophrenia. Methods The subjects of this study were 203 schizophrenic patients , grouped on the basis of suicidal ideation . Clinical characteristics were assessed using multiple scales . Neutrophil to lymphocyte ratio (NLR) , platelet to lymphocyte ratio (PLR) , monocyte to lymphocyte ratio (MLR) and thyroid hormones were also detected . SPSS 23 . 0 was used for statistical analyses . Results The prevalence of suicidal ideation was 21 . 7% in patients with schizophrenia. Logistic stepwise regression analyses showed that Cal- gary depression scale (CDSS) total score (OR = 1 . 490 , 95% CI = 1 . 287 - 1 . 724 , P < 0. 001) , insomnia severity index scale (ISI) total score (OR = 1 . 096 , 95% CI = 1 . 011 - 1 . 187 , P = 0. 025) , modified overt aggression scale (MOAS) total score (OR = 1 . 111 , 95% CI = 1 . 016 - 1 . 215 , P = 0. 021) , MLR(Ln) (OR = 15 . 123 , 95% CI = 3 . 868 - 59. 125 , P < 0. 001) , and triiodothyronine ( T3) ( OR = 0. 037 , 95% CI = 0. 003 - 0. 388 , P = 0. 006) were the independent influences of suicidal ideation . Additionally , receiver operating characteristic (ROC) curve analyses revealed that the five-item combination of CDSS total score , ISI total score , MOAS total score , MLR (Ln) , and T3 (AUC = 0. 908 , 95% CI = 0. 867 - 0. 949 , P < 0. 001) had better ability to identify suicidal idea- tion . Conclusion The risk of suicidal ideation is relatively high in patients with schizophrenia , and there may be stronger associations between suicidal ideation and depression , insomnia , aggression , MLR , and T3 .

Abstract Objective To explore the differential lipid metabolites in the plasma of mice with idiopathic pulmonary fibrosis (IPF) . Methods Thirty SPF C57BL/6 male mice were randomly divided into 2 groups with 15 mice in each group . The experimental groups were divided into control group and bleomycin (BLM) group . The model of idiopathic pulmonary fibrosis was induced by one-time intratracheal infusion of BLM ( 1 mg/kg) . Hematoxylin-eo- sin (HE) staining was used to observe the lung histopathology . The collagen fiber deposition in lung tissue was ob- served by Sirius red staining. The differential lipid metabolites in plasma of IPF mice were screened and enriched by lipidomics . Results HE staining showed that the pulmonary tissue structure was disordered , alveolar septum was broken and alveolar wall was destroyed in BLM group . Sirius red staining showed a large amount of collagen fi- ber deposition in the lung interstitium of BLM group . The results of lipidomics analysis showed that the lipid metab- olism profile of BLM group changed , 15 differential lipid metabolites were screened out , of which 11 differential lipid metabolites were up-regulated , and 4 differential lipid metabolites were down-regulated , mainly concentrated in Glycerophosphoglycerophosphates , Glycerophosphocholines , Steroid lactones , etc . Conclusion The lipid me- tabolism profile of BLM group mice changes , differential lipid metabolites such as phosphoglycolate phosphatase (PGP)(18:0/18:0) , PGP( i-12:0/i-24:0) , PGP( i-13:0/a-25:0) , and phosphatidylcholine ( PC) (18:0/14 : 0) , PC(18:3/16:0) , lysophosphatidylcholine (LPC)(16:1) , and LPC(18:3) may play an important role in the progression of IPF . These findings provide a new reference for further study of the molecular mechanism of IPF , and also provide a potential new target for clinical treatment.

Abstract Objective To investigate the effects of heat shock protein 70 ku protein 1A (HSPA1A) on H9c2 in- flammation and apoptotic injury in rat cardiomyocytes under hypoxia , and to analyze its mechanism . Methods H9c2 cells were treated with normal oxygen (Nor) and hypoxia (Hyp) , and the expression of HSPA1A was detec- ted by RT-qPCR and Western blot. Normal H9c2 cells were divided into Nor group (normoxia culture) , sh-HS- PA1A + Nor group (cells transfected with HSPA1A shRNA , normoxia culture) , Hyp group (hypoxia culture) , sh- HSPA1A + Hyp group (cells transfected with HSPA1A SHRNA , hypoxia culture) , the expression level of HSPA1A in H9c2 cells in each group was detected by RT-qPCR and Western blot , the morphology of H9c2 cells in each group was observed by inverted microscope , and the activity of H9c2 cells in each group was detected by CCK-8 , the contents of inflammatory factors tumor necrosis factor-α(TNF-α) , interleukin(IL)-6 , IL-1βand the activities of myocardial injury markers lactate dehydrogenase (LDH) , creatine kinase (CK) in the supernatant of H9c2 cells were detected by ELISA , apoptosis rate of H9c2 cells in each group was detected by Annexin V-FITC/PI double staining , the expression levels of TNF receptor-associated factor 2 (TRAF2) /nuclear factor κB (NF-κB) pathway- related proteins in H9c2 cells of each group were detected by Western blot. Results Compared with Nor group , the relative expression of HSPA1A mRNA and protein in H9c2 cells in Hyp group after hypoxia induction was sig- nificantly up-regulated (P < 0. 05) . Compared with Nor group , the number of H9c2 cells in Hyp group significant- ly decreased , some cells were wrinkled and disordered , the cell activity significantly decreased ( P < 0. 05) , the contents of TNF-α, IL-6 , IL-1βand the activities of LDH and CK in supernatant significantly increased ( P < 0. 05) , the cell apoptosis rate significantly increased (P < 0. 05) , the relative expressions of TRAF2 protein and the phosphorylation level of p65 and inhibitor of nuclear factor κB alpha (IκBα) were significantly up-regulated (P < 0. 05) ; compared with Hyp group , the morphology of H9c2 cells in sh-HSPA1A + Hyp group was improved , the cell arrangement was more dense , the cell activity significantly increased (P < 0. 05) , the contents of TNF-α, IL- 6 and IL-1βin supernatant decreased , the activities of LDH and CK significantly decreased (P < 0. 05) , the apop- tosis rate significantly decreased ( P < 0. 05) , the relative expressions of TRAF2 protein and the phosphorylation level of p65 and IκBαwere also significantly down-regulated ( P < 0. 05 ) . Conclusion The expression of HS- PA1A in rat cardiomyocytes H9c2 is increased by hypoxia , and inhibition of HSPA1A expression can improve the hypoxia-induced inflammatory response of H9c2 cells and reduce apoptosis damage , which may be related to the regulation of TRAF2/NF-κB pathway .

Abstract Objective To investigate the effect of Sirtuin 2 (SIRT2) on the proliferation and migration of cardiac forty SPF healthy male C57BL/6J mice were randomly divided into four groups : normal diet group ( ND group) , high fat diet induced obesity group (DIO group) , DIO supplemented with the control virus group (DIO + Scramble group) and DIO supplemented with the interfering virus group (DIO + shPTGES3 group) . The Morris water maze test was conducted to evaluate the cognitive behavior changes of the four groups of mice . The immunofluorescence staining was performed to detect the expression of PTGES3 and HSP90 in the medial prefrontal cortex and the acti- vation of ionized calcium binding adapter molecule 1 (IBA1)-labeled microglia. Results In the case-control stud- y , the cognitive function of obese patients significantly decreased , and the expression of PTGES3 in peripheral blood significantly increased , while the level of PTGES3 was negatively correlated with cognitive function . In ani- mal experiments , compared with ND group , DIO group had significantly prolonged time reaching the target plat- form , otherwise , the residence time in the target quadrant was shortened in the Morris water maze test. Simultane- ously , there were significant increase in the expression of PTGES3 and HSP90 , and the activation of IBA1 in the medial prefrontal cortex . Compared with DIO + Scramble group , mice in the DIO + shPTGES3 group spent less time reaching the target platform , and stayed longer in the target quadrant. The expression and co-localization levels of PTGES3 and HSP90 in medial prefrontal cortex significantly decreased . The activation level of microglia cells was also attenuated by PTGES3 interference . Conclusion Obesity-related cognitive dysfunction may be attributed to PTGES3/HSP90 in the medial prefrontal cortex by mediating neural inflammation .

Abstract Objective To predict and validate key targets for cisplatin( DDP) resistance in colorectal cancer to provide more options for precision medicine in clinical treatment. Methods Differentially expressed genes (DEGs) between normal colonic mucosa and colorectal cancer(CRC) were screened from the gene expression om- nibus(GEO) database . Key genes were identified using the STRING database and Cytoscape software . DEGs were subjected to enrichment analysis using the gene ontology ( GO) and kyoto encyclopedia of genes and genomes (KEGG) databases . Key targets were validated through RNA-seq , qRT-PCR , and Western blot. The versican (VCAN) gene overexpression vector was transfected into human ileocecal colorectal adenocarcinoma cell line HCT8 , and cell viability was assessed using the CCK-8 assay . Flow cytometry was used to assess apoptosis and cell cycle distribution . qRT-PCR and Western blot were performed to detect mRNA and protein levels of the target genes . Results In this study , 118 upregulated DEGs and 146 downregulated DEGs were identified from the GEO database . DEGs were mainly enriched in extracellular matrix degradation , extracellular matrix organization , and the phosphoinositide 3-kinase (PI3K)-protein kinase B (AKT) signaling pathway . Based on protein-protein interaction network analysis , 20 hub genes were identified . By comparing the transcriptome sequencing results of the HCT8 pa- rental strain and DDP-resistant strain , the VCAN gene was further selected . In CRC tissues , the expression level of VCAN was higher than that in normal colonic mucosa , and patients with high VCAN expression had shorter overall survival (OS) and recurrence free survival(RFS) times . Overexpression of VCAN in CRC cells promoted cell pro- liferation (P < 0. 05 ) , increased resistance to DDP , reduced DDP-induced apoptosis ( P < 0. 05 ) , and G0 /G1 phase arrest (P < 0. 05) ; upregulation of VCAN activated the protein kinase B (AKT)-mammalian target of rapam- ycin ( mTOR) signaling pathway . Conclusion Bioinformatics and transcriptome sequencing identified VCAN as a key target gene for DDP resistance in CRC , potentially promoting CRC progression and DDP resistance by regula- ting the AKT-mTOR pathway .

Abstract Objective To establish an in vitro model of ferroptosis induced by Erastin and RAS-selective lethal 3 (RSL3) in hepatoma cells , and to provide theoretical basis for the development of novel therapeutic strategies for HCC . Methods Hepatoma cells ( HCCLM3 , HepG2 , Hep3B , Huh7 and PLC/PRF/5 ) in logarithmic growth phase were treated with Erastin (0 - 40 μmol/L) and RSL3 (0 - 10 μmol/L) at double concentrations respective- ly . After 24 h , CCK-8 method was used to detect cell viability , draw growth curve , calculate IC50 , and HCC cells sensitive to inducers were selected for follow-up experiments . The effect of inducer on the state of hepatoma cells was observed under light microscope , and immunoblotting and flow cytometry were used to verify whether the fer- roptotic model in vitro was successfully constructed . Results Huh7 , Hep3B and HepG2 cells were sensitive to Erastin and RSL3 , but HCCLM3 and PLC/PRF/5 were insensitive to Erastin and RSL3 . When the concentration of Erastin and RSL3 reached the maximum , the survival rate was still above 65% . Huh7 , Hep3B and HepG2 cells were selected for subsequent experiments . Compared with the control group , the expression of Glutathione peroxi- dase 4 (GPX4) , a ferroptotic marker , was down-regulated in a concentration-dependent manner. In Huh7 , Hep3B and HepG2 cells , lipid reactive oxygen species ( ROS) levels significantly increased after 24 h treatment with 10 μmol/L and 20 μmol/L Erastin , respectively; in Huh7 cells , lipid ROS levels significantly increased after 24 h treatment with 0. 5 μmol/L and 1 μmol/L RSL3 , respectively; in Hep3B and HepG2 cells , lipid ROS levels sig- nificantly increased after 24 h treatment with 1 μmol/L and 2 μmol/L RSL3 , respectively , compared with control group . Conclusion Huh7 , Hep3B and HepG2 cells are highly sensitive to Erastin and RSL3 . Huh7 , Hep3B and HepG2 cells treated with 10 μmol/L Erastin for 24 h are good models for simulating ferroptosis induced by Erastin in vitro , Huh7 cells treated with 0. 5 μmol/L RSL3 for 24 h and Hep3B and HepG2 cells treated with 1 μmol/L RSL3 for 24 h are good models for simulating ferroptosis induced by RSL3 in vitro .

Abstract Non-small cell lung cancer (NSCLC) , the most prevalent type of lung cancer , has a poor prognosis in patients with advanced disease . In recent years , immune checkpoint inhibitors (ICIs) have demonstrated promising efficacy in this disease , while bringing a unique set of immune-related adverse events (irAEs) . This article com- prehensively explores the multi-systemic irAEs of programmed death protein-1 ( PD-1) /programmed death protein ligand-1 (PD-L1) inhibitors in the treatment of NSCLC , including but not limited to dermatotoxicity , endocrine toxicity , hepatic toxicity and gastrointestinal toxicity . The occurrence of these adverse reactions not only poses a challenge for clinical treatment , but also correlates with treatment efficacy . In addition , the paper discusses bio- markers for predicting the risk of irAEs , such as gut microbiota , blood biomarkers , etc . , with the aim of providing a potential risk assessment tool for the clinic .

Asthma is a well-characterized heterogeneous disease marked by airway remodeling and chronic air- way inflammation . Clinically , the treatment of asthma primarily relies on hormonal drugs . However , the long-term use of these medications can lead to significant side effects . Mitophagy is a biological process that selectively trans- ports damaged mitochondria to lysosomes for degradation . Recent research has revealed the crosstalk between mito- phagy and asthma. Accordingly , taking mitophagy as an entry point , summarizing the key molecular mechanisms and regulators of mitophagy in asthma will facilitate the development of novel intervention targets and strategies for asthmatic treatment.
