ObjectiveTo investigate the effects of Chaihu Jia Longgu Mulitang（CJLM） on depression-like behaviors and neuroinflammation in rats subjected to social isolation combined with chronic unpredictable mild stress（CUMS）， and to explore the potential underlying mechanisms. MethodsSixty male SD rats were randomly divided into a normal group， a model group， and low-， medium-， and high-dose CJLM groups（2.89， 5.78， 11.56 g·kg^-1）， as well as a fluoxetine group（10 mg·kg^-1）. Except for the normal group， all other groups were subjected to social isolation combined with CUMS for 63 d. During the first 35 d， depression models were established only， and from day 36 onward， modeling and drug administration were conducted simultaneously for a total intervention period of 28 d. Depression-like behaviors were evaluated using the sucrose preference test， open-field test， and forced swimming test. Hematoxylin-eosin（HE） staining was performed to observe hippocampal histomorphology. Immunohistochemistry（IHC） was used to detect the expression levels of ionized calcium-binding adapter molecule 1（Iba1） and gasdermin D（GSDMD） proteins in the hippocampus. Western blot analysis was employed to determine the protein expression levels of adenosine 5′-monophosphate（AMP）-activated protein kinase（AMPK） and phosphorylated（p）-AMPK， silent information regulator 1（SIRT1）， nuclear factor-κB（NF-κB） and p-NF-κB， NOD-like receptor protein 3（NLRP3）， and Caspase-1 in the hippocampus. Real-time quantitative polymerase chain reaction（Real-time PCR） was used to detect the mRNA expression levels of tumor necrosis factor-α（TNF-α）， interleukin（IL）-6， and IL-1β in the hippocampus. ResultsCompared with the normal group， the model group showed a decreased sucrose preference rate（P<0.01）， reduced total movement distance（P<0.01）， prolonged immobility time（P<0.01）， and decreased central zone residence time（P<0.01） in the open-field test， and increased immobility time in the forced swimming test（P<0.01）. Hippocampal neuronal structure was damaged. The contents of Iba1 and GSDMD in the hippocampus were significantly increased（P<0.01）. The protein expression levels of p-AMPK and SIRT1 in the hippocampus were significantly decreased（P<0.01）， whereas the protein expression levels of p-NF-κB， NLRP3， and Caspase-1 were significantly increased（P<0.01）. The mRNA expression levels of IL-1β， IL-6， and TNF-α in the hippocampus were significantly upregulated（P<0.01）. Compared with the model group， the low-， medium-， and high-dose CJLM groups and the fluoxetine group all were able to reverse depression-like behavioral changes， as evidenced by increased sucrose preference rate， increased total movement distance with shortened immobility time in the open-field test， prolonged central zone residence time， and reduced immobility time in the forced swimming test（P<0.05， P<0.01）. Meanwhile， hippocampal neuronal structural damage was alleviated. In the hippocampus， the expression levels of Iba1 and GSDMD were downregulated， the expression levels of p-AMPK and SIRT1 were upregulated， and the abnormal elevations of p-NF-κB， NLRP3， Caspase-1， as well as IL-1β， IL-6， and TNF-α mRNA were suppressed（P<0.05， P<0.01）. ConclusionCJLM can ameliorate depression-like behaviors in rats subjected to social isolation combined with CUMS and attenuate hippocampal neuroinflammation and pyroptosis， suggesting that its effects may be associated with the regulation of AMPK/SIRT1/NF-κB/NLRP3 signaling pathway.

Objective: To analyze the epidemiological characteristics of pulmonary tuberculosis (PTB) among college students in Yangzhou from 2020 to 2024, so as to provide a scientific basis for developing prevention and control strategies. Methods: An epidemiological investigation was conducted among 162 college students with PTB, and 7 134 of their contacts were screened. Data were obtained from the tuberculosis information management system and on campus screening records. Using descriptive epidemiological methods, trends in incidence, seasonal distribution, and bacteriological characteristics were analyzed. Results: From 2020 to 2024, the annual average incidence of pulmonary tuberculosis among college students in Yangzhou was 29.42 per 100 000, showing an overall fluctuating downward trend ( χ 2=12.36, P <0.01). Cases were mainly concentrated in summer and autumn, with the highest proportion in autumn (41.36%, 67/162), followed by summer (23.46%, 38/162). The proportion of etiologically positive cases increased from 37.21% in 2020 to 71.43% in 2024; among positive cases, the proportion of latent tuberculosis infection (LTBI) decreased from 66.67% (10/15) to 26.67% (4/15). The etiological positive rate was higher in females than in males ( χ 2= 11.76 , P <0.01). Comparison of screening methods showed that among index cases, the LTBI detection rate of the recombinant Mycobacterium tuberculosis fusion protein skin test (C-TST) was higher than that of the tuberculin skin test (TST), but the difference was not statistically significant ( χ 2=0.65, P =0.42); among close contacts, the detection rate of TST was higher than that of C-TST (15.1%,10.1%; χ 2=5.23, P <0.05). Conclusion From 2020 to 2024, the annual average incidence of pulmonary tuberculosis among college students in Yangzhou showed an overall fluctuating downward trend, with differences in TB infection screening methods and gender.

Tumor drug resistance is an important problem in the failure of chemotherapy and targeted drug therapy, which is a complex process involving chromatin remodeling. SWI/SNF is one of the most studied ATP-dependent chromatin remodeling complexes in tumorigenesis, which plays an important role in the coordination of chromatin structural stability, gene expression, and post-translation modification. However, its mechanism in tumor drug resistance has not been systematically combed. SWI/SNF can be divided into 3 types according to its subunit composition: BAF, PBAF, and ncBAF. These 3 subtypes all contain two mutually exclusive ATPase catalytic subunits (SMARCA2 or SMARCA4), core subunits (SMARCC1 and SMARCD1), and regulatory subunits (ARID1A, PBRM1, and ACTB, etc.), which can control gene expression by regulating chromatin structure. The change of SWI/SNF complex subunits is one of the important factors of tumor drug resistance and progress. SMARCA4 and ARID1A are the most widely studied subunits in tumor drug resistance. Low expression of SMARCA4 can lead to the deletion of the transcription inhibitor of the BCL2L1 gene in mantle cell lymphoma, which will result in transcription up-regulation and significant resistance to the combination therapy of ibrutinib and venetoclax. Low expression of SMARCA4 and high expression of SMARCA2 can activate the FGFR1-pERK1/2 signaling pathway in ovarian high-grade serous carcinoma cells, which induces the overexpression of anti-apoptosis gene BCL2 and results in carboplatin resistance. SMARCA4 deletion can up-regulate epithelial-mesenchymal transition (EMT) by activating YAP1 gene expression in triple-negative breast cancer. It can also reduce the expression of Ca²⁺ channel IP3R3 in ovarian and lung cancer, resulting in the transfer of Ca²⁺ needed to induce apoptosis from endoplasmic reticulum to mitochondria damage. Thus, these two tumors are resistant to cisplatin. It has been found that verteporfin can overcome the drug resistance induced by SMARCA4 deletion. However, this inhibitor has not been applied in clinical practice. Therefore, it is a promising research direction to develop SWI/SNF ATPase targeted drugs with high oral bioavailability to treat patients with tumor resistance induced by low expression or deletion of SMARCA4. ARID1A deletion can activate the expression of ANXA1 protein in HER2+ breast cancer cells or down-regulate the expression of progesterone receptor B protein in endometrial cancer cells. The drug resistance of these two tumor cells to trastuzumab or progesterone is induced by activating AKT pathway. ARID1A deletion in ovarian cancer can increase the expression of MRP2 protein and make it resistant to carboplatin and paclitaxel. ARID1A deletion also can up-regulate the phosphorylation levels of EGFR, ErbB2, and RAF1 oncogene proteins.The ErbB and VEGF pathway are activated and EMT is increased. As a result, lung adenocarcinoma is resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Although great progress has been made in the research on the mechanism of SWI/SNF complex inducing tumor drug resistance, most of the research is still at the protein level. It is necessary to comprehensively and deeply explore the detailed mechanism of drug resistance from gene, transcription, protein, and metabolite levels by using multi-omics techniques, which can provide sufficient theoretical basis for the diagnosis and treatment of poor tumor prognosis caused by mutation or abnormal expression of SWI/SNF subunits in clinical practice.

OBJECTIVE: To evaluate the clinical effect and safety of acupuncture manipulation on treatment of intractable facial paralysis (IFP), and verify the practicality and precision of the Anzhong Facial Paralysis Precision Scale (Eyelid Closure Grading Scale, AFPPS-ECGS). METHODS: A multicentre, single-blind, randomized controlled trial was conducted from October 2022 to June 2024. Eighty-nine IFP participants were randomly assigned to an ordinary acupuncture group (OAG, 45 cases) and a characteristic acupuncture group (CAG, 44 cases) using a random number table method. The main acupoints selected included Yangbai (GB 14), Quanliao (SI 18), Yingxiang (LI 20), Shuigou (GV 26), Dicang (ST 4), Chengjiang (CV 24), Taiyang (EX-HN 5), Jiache (ST 6), Fengchi (GB 20), and Hegu (LI 4). The OAG patients received ordinary acupuncture manipulation, while the CAG received characteristic acupuncture manipulation. Both groups received acupuncture treatment 3 times a week, with 10 times per course, lasting for 10 weeks. Facial recovery was assessed at baseline and after the 1st, 2nd and 3rd treatment course by AFPPS-ECGS and the House-Brackmann (H-B) Grading Scale. Infrared thermography technology was used to observe the temperature difference between healthy and affected sides in various facial regions. Adverse events and laboratory test abnormalities were recorded. The correlation between the scores of the two scales was analyzed using Pearson correlation coefficient. RESULTS: After the 2nd treatment course, the two groups showed statistically significant differences in AFPPS-ECGS scores (P<0.05), with even greater significance after the 3rd course (P<0.01). Similarly, H-B Grading Scale scores demonstrated significant differences between groups following the 3rd treatment course (P<0.05). Regarding temperature measurements, significant differences in temperatures of frontal and ocular areas were observed after the 2nd course (P<0.05), becoming more pronounced after the 3rd course (P<0.01). Additionally, mouth corner temperature differences reached statistical significance by the 3rd course (P<0.05). No safety-related incidents were observed during the study. Correlation analysis revealed that the AFPPS-ECGS and the H-B Grading Scale were strongly correlated (r=0.86, 0.91, 0.93, and 0.91 at baseline, and after 1st, 2nd, and 3rd treatment course, respectively, all P<0.01). CONCLUSIONS Acupuncture is an effective treatment for IFP, and the characteristic acupuncture manipulation enhances the therapeutic effect. The use of the AFPPS-ECGS can more accurately reflect the recovery status of patients with IFP. (Trial registration No. ChiCTR2200065442).

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

ObjectiveTo explore the regulatory effects and mechanisms of Astragali Radix polysaccharide （APS） on inhibitor of differentiation1 （ID1） and protein kinase B （Akt） in gastric cancer. MethodsImmunohistochemical staining was used to detect the expression of ID1 and Akt in 61 gastric cancer tissue samples and 20 adjacent normal gastric tissue samples. Immunofluorescence was used to detect the localization of ID1 and Akt. The effects of APS at the concentrations of 0.625， 1.25， 2.5， 5， 10， 20 mg·L^-1 on the proliferation of gastric cancer MGC-803 cells were examined by the cell counting kit-8（CCK-8） method and the colony formation assay. The target information of APS was retrieved from the Traditional Chinese Medicine Systems Pharmacology and Analysis Platform and Swiss Target Prediction. Keywords such as gastric cancer， gastric tumor， and stomach cancer were searched against GeneCards， UniProt， DisGeNET， and Online Mendelian Inheritance in Man （OMIM） for the screening of gastric cancer-related targets. The online tool jvenn was used to create the Venn diagram to identify the common targets， and STRING and Cytoscape were used to construct the protein-protein interaction network. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses were conducted via R 4.2.2 to predict the potential roles of APS in the development of gastric cancer. The cell scratch assay was employed to assess the effect of APS on the migration of MGC-803 cells. The protein and mRNA levels of ID1 and Akt in the cells treated with APS were determined by Western blot and Real-time PCR， respectively. ResultsCompared with the adjacent normal gastric tissue， the gastric adenocarcinoma tissue showed increased positive expression of ID1 （χ² =81.00， P<0.01）. Immunofluorescence detection showed that ID1 and Akt were mainly located in the cytoplasm of gastric adenocarcinoma cells. Bioinformatics analysis identified 14 common genes shared between APS and gastric cancer. The average degree of protein-protein interaction network nodes was 14.29. GO and KEGG pathway enrichment results showed that ID1 and Akt were significantly enriched in the Rap1 and phosphatidylinositol-3-kinase （PI3K） /Akt signaling pathways. Cell experiments demonstrated that 5-fluorouracil （0.1 mg·L^-1） and APS （10， 20 mg·L^-1） groups showed decreased cell proliferation， migration， and colony formation. Compared with the control group， 10， 20 mg·L^-1 APS inhibited the proliferation of MGC-803 cells （P<0.01）， with 10 mg·L^-1 APS demonstrating stronger inhibitory effect. In addition， APS at 10， 20 mg·L^-1 inhibited the migration （P<0.01） and colony formation （P<0.05， P<0.01） of MGC-803 cells. Compared with the control group， APS at 10， 20 mg·L^-1 down-regulated the protein levels of ID1 （P<0.01） and Akt （P<0.05） and the mRNA levels of ID1 （P<0.05， P<0.01） and Akt （P<0.05， P<0.01） in MGC-803 cells. ConclusionID1 and Akt are highly expressed in the gastric adenocarcinoma tissue， which may be related to the development of gastric cancer. APS can down-regulate the protein and mRNA levels of ID1 and Akt to exert anti-tumor effects， which is expected to provide new therapeutic targets for gastric cancer treatment.

Objective To explore the impact of polymorphisms in the solute carrier organic anion transporter family member 1B1(SLCO1B1)and apolipoprotein E(APOE)genes on statins selection and prognosis in patients after percutaneous coronary intervention(PCI).Methods This retrospective study enrolled 612 patients with coronary heart disease hospitalized in Tianjin Beichen Hospital from January 2021 to February 2023.Among them,411 patients who underwent PCI were assigned to PCI group,and 201 patients who did not undergo PCI were assigned to non-PCI group.According to treatment methods,PCI group was further divided into two subgroups:observation subgroup(n=305)and control subgroup(n=106).Non-PCI group was also divided into two subgroups:observation subgroup(n=147)and control subgroup(n=54).Patients in all observation subgroups underwent the detection of SLCO1B1 and APOE gene polymorphisms before medication,and an initial individualized treatment plan(including the selection of appropriate statins and dosages)was formulated based on the detection results.Patients in control subgroups were given statins at conventional dosages.Basic data before medication,post-medication lipid compliance rates[lipid intention-to-treat(ITT)compliance rate and lipid per-protocol analysis(PP)compliance rate],time to lipid compliance,liver function indicators before and after medication,and prognosis,as well as SLCO1B1 and APOE genotyping and allele frequency distribution were compared between observation subgroup and control subgroup.Conditional logistic regression was used to analyze the relationship between different genotypes and prognostic susceptibility.Multifactor dimensionality reduction(MDR)was applied to analyze the interaction between SLCO1B1 genotype and APOE genotype.Results All genotypes of SLCO1B1 and APOE genes in observation subgroups conformed to the Hardy-Weinberg genetic equilibrium test(P>0.05).Compared with control subgroups,the observation subgroups had significantly higher lipid PP compliance rates after 6 and 12 months of treatment.After 3 months of treatment,the number of completed cases and compliant cases in observation subgroups was significantly higher,and the time to lipid compliance was significantly shorter than that in control subgroups(P<0.05).Compared with before treatment,there were no significant changes in alanine aminotransferase(ALT)and creatine kinase isoenzyme(CK-MB)levels in either observation subgroups or control subgroups(P>0.05);the levels of total cholesterol(TC),triglycerides(TG),and low-density lipoprotein cholesterol(LDL-C)were significantly decreased(P<0.001),while high-density lipoprotein cholesterol(HDL-C)level was significantly increased(P<0.01).After 12 months of treatment,the aspartate aminotransferase(AST)level in observation subgroups was significantly lower than that before medication and also lower than that in the corresponding control subgroups(P<0.05).Within PCI group:there were 1 case and 5 cases of myocardial infarction,2 cases and 6 cases of target vessel revascularization,0 cases and 3 cases of stroke,0 cases and 7 cases of recurrent angina pectoris,1 case and 5 cases of readmission in observation subgroup and control subgroup,respectively.There were statistically significant differences between observation subgroup and control subgroup(P<0.05).Within non-PCI group:there were 0 cases and 3 cases of cardiogenic death,2 cases and 6 cases of myocardial infarction,2 cases and 5 cases of target vessel revascularization,0 cases and 4 cases of stroke,0 cases and 8 cases of recurrent angina pectoris,and 2 cases and 4 cases of readmission in observation subgroup and control subgroups,respectively,with statistically significant differences between the two subgroups(P<0.05).In the recessive model,SLCO1B1 and APOE genes were significantly correlated with prognosis in both PCI observation subgroup and non-PCI observation subgroup(P<0.05).MDR analysis of the interaction between SLCO1B1 genotype and APOE genotype in PCI observation subgroup and non-PCI observation subgroup showed that there was a significant interaction between the genotypes,which was closely related to prognosis(P<0.05).Conclusion Individualized statin treatment regimens based on the detection of SLCO1B1 and APOE gene polymorphisms can improve the lipid compliance rate,shorten the time to lipid compliance,and improve the prognosis of patients after PCI.

Objective To analyze the predictive value of patient-reported outcomes(PRO)com-bined with hematological indicators for moderate-to-severe endoscopic activity in patients with ulcera-tive colitis(UC).Methods Clinical data of UC patients were retrospectively collected,including PRO,hematological parameters and endoscopic findings.Based on the Mayo endoscopic score,pa-tients were divided into remission and mild activity group(＜2 points)and moderate-to-severe activity group(≥ 2 points).Independent influencing factors for moderate-to-severe endoscopic activity were screened through multivariate Logistic regression analysis,and a binary Logistic regression model was constructed.The receiver operating characteristic(ROC)curve was used to evaluate the discriminato-ry ability of the predictive model.The calibration of the model was assessed using calibration curves and the Spiegelhalter Z-test,and the model's performance was further validated in an external valida-tion cohort.Results Rectal bleeding(RB),C-reactive protein/albumin(CAR)and erythrocyte sed-imentation rate(ESR)were independent influencing factors for moderate-to-severe endoscopic activity(P＜0.05).The area under the curve(AUC)of the nomogram predictive model constructed based on the logistic regression analysis results was 0.848(95％CI,0.798 to 0.900),with sensitivity of 76.6％and specificity of 79.6％.In the external validation cohort,the model's AUC was 0.778(95％CI,0.699 to 0.857),and there was no statistically significant difference compared with the AUC of the training cohort model(P＞0.05).In both the training and validation cohorts,the Spiegelhalter Z-test results indicated that the model had good goodness-of-fit(P＞0.05).Conclu-sion RB,CAR and ESR are independent influencing factors for moderate-to-severe endoscopic ac-tivity in UC patients.The combination of RB,CAR and ESR has high predictive value for moderate-to-severe endoscopic activity in UC patients,with good discriminatory and calibration abilities.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.
