ObjectiveTo investigate the association between endothelin receptor type A gene （EDNRA） and congenital bilateral absence of the vas deferens （CBAVD）. MethodsThis case-control study consisted of 124 subjects with CBAVD and 100 fertile controls.Two single nucleotide polymorphisms （SNPs： rs5335 and rs1801708） in the EDNRA gene were genotyped via PCR， PCR-RFLP analysis， and direct sequencing. ResultsNo significant differences existed between EDNRA polymorphisms and CBAVD phenotype （rs1801708： P=0.220 2， 0.163 2； rs5335： P=0.805 8， 0.818 6）. However， the rs1801708-rs5335 haplotype AG was notably associated with an increased risk of CBAVD （P=0.008 6， OR=2.178， 95% CI： 1.207-3.929）. A significantly protective effect of rs1801708-rs5335 haplotype GG on CBAVD （P=0.038 5， OR= 0.671， 95% CI： 0.460-0.980） was observed. After Bonferroni correction， the result for haplotype A-G remained significant （P =0.008 6<0.012 5）， while haplotype G-G was not significant. ConclusionThe rs1801708-rs5335 AG haplotype of EDNRA is a potential risk factor for CBAVD development in Han Chinese.

OBJECTIVE:Postoperative recurrence is a common complication of percutaneous endoscopic lumbar discectomy for lumbar disc herniation,which can significantly increase the risk of reoperation.A well-performing risk prediction model can help identify high-risk groups early and prevent postoperative recurrence.This study systematically evaluated the risk prediction model for postoperative recurrence after percutaneous endoscopic lumbar discectomy to provide a reference for surgical decision-making.METHODS:The PubMed,Embase,Web of Science,CNKI,WanFang Data,VIP,and CBM were electronically searched to collect studies on the recurrence risk prediction models after percutaneous endoscopic lumbar discectomy from inception to July 1,2024.Two reviewers independently screened the literature and extracted data.The models' risk of bias,applicability,and report quality were assessed using prediction model risk of bias assessment tool(PROBAST)and Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis(TRIPOD)tools,respectively.Meta-analysis of postoperative recurrence rate of percutaneous endoscopic lumbar discectomy and related predictors was performed using Revman 5.4 software.RESULTS:(1)A total of 15 studies were included,all of which were retrospective studies,including 24 models for predicting the risk of recurrence after percutaneous endoscopic lumbar discectomy.(2)The PROBAST evaluation results indicated that all 15 studies exhibited a high risk of bias.Regarding applicability,two studies demonstrated a low risk,while 13 presented a high risk.(3)Regarding the TRIPOD reporting quality,the overall quality across the 15 studies was low.The primary reasons for this low compliance included the failure to report blinding,a lack of explanation for the sample size calculation method,lack of detailed description of missing data processing methods,and lack of information such as introduction to the model used.(4)Furthermore,the area under the receiver operating characteristic curve for the model ranged from 0.684 to 0.972,with the number of potential predictor variables varying from 15 to 28.(5)The results of meta-analysis showed that the postoperative recurrence rate of lumbar disc herniation patients treated with percutaneous endoscopic lumbar discectomy was 12％(95％CI=9.0％-15.0％),Modic changes(OR=6.72,95％CI=3.90-11.59),body mass index(OR=1.28,95％CI=1.10-1.49),work intensity(OR=3.22,95％CI=1.85-5.59),age(OR=2.28,95％CI=1.50-3.48),and smoking history(OR=2.65,95％CI=1.75-4.00)were independent influencing factors for postoperative recurrence of percutaneous endoscopic lumbar discectomy(all P＜0.05).CONCLUSION:The overall predictive performance of the recurrence risk prediction models after percutaneous endoscopic lumbar discectomy is satisfactory;however,the model exhibits a high overall risk of bias and applicability,coupled with low reporting quality.Additionally,there is a lack of prospective research and external validation.Future,risk prediction models should consider factors such as Modic changes,body mass index,work intensity,age,and smoking history as potential predictors.

As one of the most common malignant tumors， digestive system tumors exhibit an increase in the incidence and mortality year by year. Its pathogenesis is complex， making it difficult to carry out early prevention. Autophagy is a process in which cells use lysosomes to degrade their organelles and macromolecules to maintain cellular homeostasis under the regulation of autophagy-related genes. Cellular autophagy has a dual regulatory effect on the tumor microenvironment， which always affects the occurrence and development of digestive system tumors. Therefore， the effect and mechanism of action of cellular autophagy on digestive system tumors have become a hot topic in tumor therapy in recent years. Meanwhile， the remarkable research results of targeted autophagy drugs indicate that cellular autophagy may become an important target for anti-digestive system tumors. Traditional Chinese medicine （TCM） has been widely used in the comprehensive treatment of digestive system tumors with good efficacy. A variety of active ingredients in TCM， such as flavonoids， glycosides， terpenoids， quinones， and alkaloids， can increase the expression of autophagy-associated proteins microtubule-associated protein 1 light chain 3 （LC3）Ⅱ/Ⅰ， autophagy-related gene （ATG）5， ATG7， inhibit the expression of autophagy-related protein p62 ， and induce autophagy in digestive system tumor cells， thereby exerting the anti-digestive system tumor effect. By summarizing the research results in recent years on the modulation of cell autophagy by active ingredients in TCM to fight against digestive system tumors， this paper analyzed the relevant signaling pathways， regulatory factors， and functional characteristics of cell autophagy modulation， so as to elucidate the mechanism by which active ingredients of TCM induce autophagy and to provide ideas and references for clinical application.

Objective:To develop the Body Image Flexibility Questionnaire for Middle School Students(BIFQ-MS)and test its validity and reliability.Methods:Firstly,the initial questionnaire was developed based on the hexaflex model of psychological flexibility.Secondly,701 middle school students were selected to complete the initial questionnaire for item analysis and exploratory factor analysis.Thirdly,899 middle school students were ex-amined to conduct confirmatory factor analysis,criterion-related validity and internal consistency tests on the formal questionnaire.The Body Image-Acceptance and Action Questionnaire(BI-AAQ),Avoidance and Fusion Question-naire for Youth(AFQ-Y8),Body Areas Satisfaction Scale(BASS),and General Appearance subscale of the Nega-tive Physical Self Scale(NPSS-GA)were used to test criterion validity.In addition,88 middle school students were retested 4 weeks later.Results:The BIFQ-MS consisted of 26 items,including 4 factors(openness to experience,self-as-context,contact with the present moment,and valued action),which explained 65.55％of the total vari-ance.Confirmatory factor analysis showed that the four-factor structural model fitted well(x2/df=2.26,CFI=0.97,TLI=0.97,RMSEA=0.04,SRMR=0.03).The BIFQ-MS total scores and the scores of each factor were positively correlated with the scores of the BI-AAQ and the BASS(r=0.41-0.50,Ps＜0.01),whereas they were negatively correlated with the scores of the NPSS-GA and the AFQ-Y8(r=-0.28--0.58,Ps＜0.01).The Cronbach's α coefficients of the total questionnaire and the 4 factors ranged from 0.91 to 0.97,and the test-retest reliabilities(ICC)ranged from 0.70 to 0.86.Conclusion:The Body Image Flexibility Questionnaire for Middle School Students is a reliable tool for understanding body image flexibility in adolescents.

AIM:To investigate the antiviral effica-cy and mechanism of Qingre Xiaoyanning(QRXYN)in vivo,and provide experimental basis for their prevention and treatment of influenza A virus.METHODS:We constructed a mouse model infect-ed with influenza A H3N2 virus.To evaluate the therapeutic effect of QRXYN on influenza A virus,we measured the body weight changes,pathologi-cal changes in lung tissue,hemagglutination titer,and viral load in mouse.To evaluate the possible mechanism of QRXYN's anti influenza A virus infec-tion,we used the ELISA to measure the levels of TNF-α,IL-1β,IL-4,IFN-γ,and vascular cell adhesion molecule-1(VCAM-1)in mouse bronchoalveolar Ia-vage fluid;used flow cytometry to assess the pro-portions of macrophages(F4/80),helper T lympho-cytes(CD4+T lymphocytes),and natural killer(NK)cells in lung tissue;and used Western blotting to detect the expression of Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MYD88),inhibitor of kappa B kinase-β(IKK-β),NF-kappa-B inhibitor al-pha(IκBα),and phospho-IKB alpha(p-IκBα)in lung tissue.RESULTS:Compared to the model group,both Oseltamivir and QRXYN can alleviate the se-verity of lung tissue lesions in mice,decrease the blood coagulation titer and viral load of mouse lung tissue(P＜0.01),lower the levels of TNF-α,IL-4,and VCAM-1 in bronchoalveolar lavage fluid(P＜0.05,P＜0.01),reduce the proportion of macro-phages(P＜0.05,P＜0.01),and increase the propor-tion of CD4+T lymphocytes and NK cells(P＜0.05,P＜0.01).Additionally,oseltamivir can reduce the ex-pression of MYD88 protein in mouse lungs(P＜0.05),while QRXYN can decrease the expression of IKK-β and P-IκBα proteins in mouse lungs(P＜0.05).CONCLUSION:QRXYN have good in vivo antiviral ef-fects against the influenza A virus,and their mecha-nism may be related to the regulation of the immu-nologic function and NF-κB signal pathway.

Objective:To investigate the clinical efficacy of artificial humeral head replacement versus locking plate internal fixation in the treatment of comminuted proximal humeral fractures in older adult patients. Methods:A total of 30 older adult patients with proximal humeral comminuted fractures, admitted to Beifang Hospital, Huainan Xinhua Medical Group from January 2022 to December 2024, were included in this study. A prospective randomized controlled study design was used. The patients were divided into an observation group and a control group using a random number table method, with 15 patients in each group. The observation group underwent artificial humeral head replacement surgery, while the control group received internal fixation with a proximal humeral locking plate. Clinical treatment outcomes, shoulder joint function recovery, and complications were observed and compared between the two groups.Results:The intraoperative blood loss in the observation group was less than that in the control group [(182.24 ± 24.36) mL vs. (245.17 ± 46.08) mL]. The surgery duration [(71.84 ± 7.52) minutes vs. (93.67 ± 12.50) minutes] and hospital stay [(11.37 ± 1.89) days vs. (13.52 ± 2.67) days] were also significantly shorter in the observation group compared with the control group ( t = 4.68, 5.80, 2.55, all P < 0.05). The range of motion in the shoulder joint was greater in the observation group compared with the control group [forward elevation: (94.47 ± 7.66) ° vs. (86.14 ± 5.15) °, external rotation: (61.35 ± 6.57) ° vs. (52.40 ± 4.82) °, and internal rotation: (74.35 ± 4.80) ° vs. (62.76 ± 3.59) °]. The total Constant-Murley score was higher in the observation group [(92.91 ± 10.58) vs. (76.29 ± 7.48)], and the rate of excellent recovery of shoulder function was also higher in the observation group [73.33% (11/15) vs. 53.33% (8/15)] compared with the control group. The incidence of complications was lower in the observation group [6.66% (1/15) vs. 33.33% (5/15)] compared with the control group. All differences were statistically significant ( t = 3.50, 4.25, 7.49, 4.97, χ2 = 4.12, 5.12, all P < 0.05). Conclusions:For older adult patients with severe osteoporosis or irreparable proximal humeral comminuted fractures, artificial humeral head replacement yields more favorable outcomes compared with locking plate internal fixation, resulting in a better recovery of shoulder joint function.

Objective:To analyze the current status, influencing factors and action pathways of quality of life in patients with cardiovascular disease.Methods:From July 2023 to June 2024, a convenience sampling method was used to obtain 2 702 patients with cardiovascular disease from 9 hospitals in Guangxi Zhuang Autonomous Region.The general information questionnaires, item short form health survey, self-rating depression scale, self-rating anxiety scale, type D personality scale-14, and type A behavior pattern scale were used for investigation.SPSS 26.0 and AMOS 24.0 softwares were used for data statistical analysis.The current status of quality of life were analyzed through descriptive statistics, the influencing factors of quality of life were analyzed using multiple linear regression analysis models, and the relationship between statistical variables was analyzed through paths.Results:The overall quality of life score of patients with cardiovascular disease was (59.29±17.59).Compared with the domestic normal population norm, the 8 factors had statistically significant differences ( t=16.50-44.16, all P<0.001).The results of multiple regression analysis showed that age, marital status, low per capita monthly income, lack of exercise, irregular daily life, poor appetite, unhealthy diet, poor sleep quality, hypertension, coronary heart disease, chronic heart failure, heart valve disease, multiple types of medication taken daily, anxiety level, depression level, type D personality, and type A personality all had negative predictive effects on quality of life ( B=-0.862--0.205, all P<0.05).Demographic and life factors affected the quality of life through 4 paths, and their direct effect and indirect effect were -0.183, 0.224 respectively (there was a masking effect).Disease-related factors affected life through 2 paths, and its direct effect and indirect effect were -0.341, 0.255 respectively (there was a masking effect).Psychological factors directly and negatively affected the quality of life through one path, and its effect value was -0.651. Conclusion:The quality of life of patients with cardiovascular disease is generally at a moderate to low level.The factors that affect the quality of life of patients with cardiovascular disease produce effects through multiple pathways in a multi-combined state.
