Objective To compare the differences in clinical prognosis and safety between thoracic endovascular aortic repair(TEVAR)combined with bare metal stent(BMS)implantation therapy and TEVAR alone in patients with type B aortic dissection(TBAD)after 6 months.Methods The clinical and imaging data of patients diagnosed with TBAD and treated with TEVAR or TEVAR combined with BMS implantation in Nanyang Central Hospital from March 2023 to March 2024 were retrospectively collected.The patients were divided into TEVAR group and TEVAR+BMS group according to different treatment methods.The aortic remodeling indicators and postoperative complications at discharge and 6 months after surgery were compared between the two groups.Results A total of 37 patients were included,including 20 patients in the TEVAR group and 17 patients in the TEVAR+BMS group.There were no statistically significant differences in baseline data between the two groups(all P＞0.05);at discharge and 6 months after surgery,the true lumen diameters and true lumen ratios of the abdominal aorta(proximal level of the celiac trunk and proximal level of the left renal artery)in the TEVAR+BMS group were better than those in the TEVAR group(all P＜0.05);the degree of thrombosis of the false lumen at 6 months after surgery was better in the TEVAR+BMS group than in the TEVAR group(P＜0.05);there was no statistically significant difference in postoperative complications between the two groups(P＞0.05).Conclusions TEVAR combined with BMS implantation therapy can significantly improve the aortic remodeling effect of patients with TBAD,without increasing the risk of postoperative complications and death caused by aortic-related factors.Bare stent implantation as an auxiliary treatment method for endovascular repair is a safe and effective optimized treatment plan.

Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.

Objective: To investigate the effect of intraarticular hemorrhage on extending knee joint contracture model in rats . Methods: 18 mature male SD rats were divided into 3 groups by random number table method . The control group ( group C) was not immobilized and was killed after 4 weeks of feeding . In the simple fixation group( M1 group) , the left lower limb knee joint was immobilized in straight position for 4 weeks . The blood fixationgroup (M2 group) was injected into the knee cavity with body blood and immobilized in a straight position for 4 weeks . The knee joint motion of each group was measured by the joint motion measuring instrument under a stand⁃ard torque . The contracture degree was calculated by the joint range of motion of the knee joint before and after muscles separation . HE staining and Masson staining were used to detect the number of cells and collagen deposi⁃tion in the anterior joint capsule . The protein expressions of transforming growth factor 1 (TGF⁃ β1) , wingless⁃type MMTV integration site family , member 1 ( Wnt1) and beta⁃catenin ( β⁃catenin) in the anterior articular capsule were detected by Western blotting . Results: Compared with group C , total knee contracture and arthrogenic con⁃tracture of rats in M1 and M2 groups increased , and the difference was statistically significant (P < 0. 05) . At the same time , the degree of total contracture and arthrogenic contracture in M2 group was higher than that in M1 group , and the difference was statistically significant (P < 0. 05) . Compared with group C , the number of anterior joint capsule cells and collagen deposition in M1 and M2 groups increased , and the difference was statistically sig⁃group were higher than those in M1 group , and the difference was statistically significant (P < 0. 05) . Compared with group C , the protein expressions of TGF⁃ β1 , Wnt1 and β ⁃catenin in the anterior articular capsule of rats in M1 expressions of TGF⁃ β1 , Wnt1 and β ⁃catenin in the anterior articular capsule of the knee joint in M2 group were sig⁃nificantly higher than those in M1 group , with statistical significance (P < 0. 05) . Conclusion Joint immobiliza⁃ tion can lead to joint contracture , and joint bleeding aggravates the degree of joint capsule fibrosis induced by im⁃mobilization .

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Objective:To characterize the vaginal flora of pregnant women during the second trimester using full-length 16S rRNA sequencing.Methods:A total of 142 pregnant women were systematically sampled from a pregnancy cohort. Vaginal swabs were collected for full-length 16S rRNA gene sequencing，and bioinformatics analysis was performed to characterize the vaginal microbiota and identify associated influencing factors.Results:Among the 142 pregnant women，the most frequently detected species were Lactobacillus iners（83.10%，118/142）and Lactobacillus crispatus（49.30%，70/142）. The majority of samples（90.85%，129/142）were classified as Lactobacillus-dominant vagitypes，with the Lactobacillus iners vagitype accounting for 48.59%（69/142）and the Lactobacillus crispatus vagitype accounting for 38.73%（55/142）. The vaginal microbiota was clustered into five community state types（CSTs）：Ⅰa，Ⅰb，Ⅲa，Ⅲb，and Ⅳ. The most prevalent CSTs were Lactobacillus iners-dominated CST-Ⅲ（51.41%，73/142）and Lactobacillus crispatus-dominated CST-Ⅰ（24.65%，35/142）. No samples were classified as CST-Ⅱ or CST-Ⅴ. A significant negative correlation was observed between Lactobacill and vaginosis-associated bacteria. Age，alcohol consumption，smoking，and vaginal treatments showed significant associations or trends toward significance with various Alpha diversity indices. Vaginal douching was associated with CST clustering，while obstetric history（primiparity，previous miscarriage history）was associated with vagitype classification. However，no significant associations were identified between maternal baseline characteristics and Beta diversity indices. Conclusions:Full-length 16S rRNA gene sequencing reveals that the vaginal microbiota of pregnant women is dominated by Lactobacillus iners and Lactobacillus crispatus. Maternal age，lifestyle factors such as smoking and alcohol consumption，and obstetric history are significantly associated with variations in vaginal microbiota composition.

Objective To explore the evidence for Traditional Chinese Medicine(TCM)in the treatment of premature ovarian insufficiency(POI)based on evidence map and re-evaluation of systematic reviews.Methods CNKI,WanFang Data,VIP,SinoMed,PubMed,Embase,Cochrane Library and Web of Science database were electronically searched to collect systematic reviews(SR)/Meta-analysis on the treatment of POI with TCM from the inception to March 31,2025.The reporting quality,methodological quality,and evidence quality of the included studies were evaluated using the PRISMA 2020 Statement,AMSTAR 2 Checklist,and GRADE system,respectively.The interventions,number of studies,and evidence grades were comprehensively displayed using evidence map.Results A total of 15 SR/Meta-analysis were included,comprising 9 Chinese articles and 6 English articles.The PRISMA 2020 checklist evaluation revealed that 8 articles had certain deficiencies in reporting,while 7 articles demonstrated relatively complete reporting.Based on the AMSTAR 2 checklist,5 articles were rated as high-level and 10 as very low-level.A total of 10 primary outcome indicators were involved,reported 133 times.When classified using the GRADE system,there were 20 pieces of moderate-quality evidence,58 pieces of low-quality evidence,and 55 pieces of very low-quality evidence.The evidence map showed that TCM alone or in combination with hormone therapy could effectively treat POI,reduce follicle-stimulating hormone and luteinizing hormone levels,increase estradiol levels,and improve clinical manifestations and TCM syndrome manifestations.Conclusion TCM has certain advantages in the treatment of POI,enhancing the overall treatment effect,alleviating clinical symptoms of low estrogen,and regulating sex hormone levels to some extent.However,there are deficiencies in methodological quality and reporting quality,and the level of evidence is not high.Therefore,the findings should be used with caution in clinical practice.

Objective:To investigate the application value of self-pulling latter transection(SPLT)in esophagojeju-nal anastomosis during total laparoscopic total gastrectomy.Methods:From January 2021 to December 2023,80 pa-tients who underwent total laparoscopic total gastrectomy at the Department of General Surgery,Yancheng Third People's Hospital,were selected.Patients were grouped based on the intraoperative esophagojejunal anastomosis method:the SPLT group(35 cases,using SPLT esophagojejunostomy)and the Overlap group(45 cases,using esoph-agojejunal overlapping side-to-side anastomosis).Surgical related indicators,complication incidence,nutritional status,and quality of life assessment were compared between the two groups.Results:The time to first postoperative anal exhaust,the number of lymph nodes dissected,and the postoperative hospital stay were compared between the two groups(P＞0.05).The SPLT group had shorter operation time and esophagojejunal anastomosis time,and less intraopera-tive blood loss compared to the control group(P＜0.05).The incidence of postoperative complications in the SPLT group was 8.57%,and in the Overlap group was 11.11%,with no significant difference between the two groups(P＞0.05).The nutritional status at 6 months postoperatively in the SPLT group[Hb(116.97±10.94)g/L、ALB(39.74±1.29)g/L、PA(0.30±0.45)g/L]and Overlap group[Hb(119.78±12.84)g/L、ALB(39.64±1.42)g/L、PA(0.30±0.36)g/L]were compared(P＞0.05).The quality of life assessment(overall health status,functional domains,symptom domains)at 6 months postoperatively between the SPLT group and the Overlap group was compared(P＞0.05).Conclusion:The use of SPLT esophagojeju-nal anastomosis in total laparoscopic total gastrectomy can improve the surgical efficiency,achieve high anastomosis,and its medium and short-term safety is comparable to that of esophagojejunal overlap side-to-side anastomosis.

Objective:To explore common characteristics and core challenges in the family parenting process of preschool children, identify key issues in parenting practices in rural revitalization areas, and provide a reference for developing localized family intervention strategies in China.Methods:Using purposive sampling, caregivers of preschool children ( n=26) were recruited from a kindergarten in Shuangbai County, Chuxiong Yi Autonomous Prefecture, Yunnan Province, from May to August 2024. A descriptive qualitative research method was adopted. Directed content analysis and conventional content analysis were combined to analyze interview transcripts and family parenting records, extracting core themes and characteristic issues in parenting practices. Results:A total of 881 minutes of interviews were conducted, resulting in approximately 260 000 words of transcripts and text materials. A total of five core themes and 13 sub-themes were summarized, covering access to health information and scientific parenting knowledge, imbalance between parenting needs and objective resource supply, safety care, responsive care, and weak family collaboration systems.Conclusions:Families in rural revitalization areas currently face problems such as limited access to information, insufficient scientific parenting resources, and weak family collaboration functions. It is recommended to optimize parenting practices by deepening the integration of medical and educational resources, strengthening health information channels, and building an integrated "family-school-community" intervention framework.
