ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy （DR）. MethodsFourteen research centers participated in this study， which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group （120 cases） and a control group （120 cases）. The observation group was treated with Tangning Tongluo tablets， and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision， DR progression rate， retinal microhemangioma， hemorrhage area， exudation area， glycosylated hemoglobin （HbA1c） level， and TCM syndrome score were assessed before and after treatment， and the safety was observed. ResultsThe vision changed in both groups after treatment （P<0.05）， and the observation group showed higher best corrected visual acuity （BCVA） than the control group （P<0.05）. The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups， while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment， the number of microhemangiomas decreased in both the observation group （Z=-1.437， P<0.05） and the control group （Z=-2.238， P<0.05）， and it showed no significant difference between the two groups. As the treatment time prolonged， the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment， the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment， neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time， both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR， being capable of improving vision and reducing hemorrhage and exudation in the fundus.

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 propose a whole-life cycle management model for valvular heart disease (VHD), systematically elucidate its underlying logic and implementation pathways, and concurrently review and analyze its preliminary application outcomes. Methods Since 2020, West China Hospital of Sichuan University has established a management system encompassing "assessment-decision-intervention-follow-up", including: (1) a risk-stratified, tiered management pathway; (2) six core functions ("promotion, screening, prevention, diagnosis, treatment, and rehabilitation") coordinated by disease-specific managers; (3) an intelligent decision support information platform; and (4) a collaborative network of multidisciplinary teams and regional academic alliances. To evaluate the effectiveness of this management model, we retrospectively included three cohorts: (1) the population screened by echocardiography from 2020 to 2024, analyzing the detection rate of aortic valve disease and risk stratification; (2) patients enrolled in the whole-life cycle management from April 2021 to December 2024, assessing follow-up outcomes, hospital satisfaction, and changes in quality of life; (3) patients who underwent transcatheter aortic valve replacement (TAVR) from January 2022 to January 2024, evaluating the one-year all-cause mortality rate, perioperative complications, and improvements in New York Heart Association (NYHA) classification. Results Between 2020 and 2024, a total of 583 874 individuals underwent echocardiographic screening. A total of 48 089 patients with aortic valve disease were identified, including 3 401 (7.1%) high-risk patients, 18 657 (38.8%) moderate-risk patients, and 26 031 (54.1%) low-risk patients. Among them, 2 417 patients were enrolled in whole-life cycle management. Patient satisfaction scores showed a yearly increase, rising from 73.89 points before 2020 to 93.74 points in 2024. The 1-year mortality rate in the TAVR cohort decreased to 5.3%, significantly lower than the 8.2% observed under early standard management between 2014 and 2019 (P<0.01). Conclusion Through process optimization and resource integration, the VHD whole-life cycle management model has demonstrated significant effectiveness in standardizing diagnostic and follow-up procedures, enhancing patient satisfaction and quality of life, and reducing mortality. These outcomes highlight its practical value for broader implementation in China.

Objective To explore the biological function and downstream mechanism of ETS1 in glioma.Methods Bioinformatics and immunohistochemistry were used to analyze the differential expression characteristics of ETS1 in gliomas;qRT-PCR was employed to detect the expression level of ETS1 mRNA and lncRNA X-inactive specific transcript(XIST).CCK-8 and 5-ethyl-2′-deoxyuridine experiments were conducted to detect cell growth.Western blot was used to detect the expression of apoptosis-related proteins(Bax,Bak,Bcl-2).PROMO database was utilized to predict the binding sites between ETS1 and XIST promoter.Dual-luciferase reporter gene assay and chromatin immunoprecipitation-quantitative polymerase chain reaction assays were performed to verify the binding relationship between ETS1 and the XIST promoter region.cBioPortal database was used to analyze the correlation between the expression of ETS1 mRNA and XIST in glioma tissues.Results The expression levels of ETS1 mRNA and protein were significantly upregulated in glioma(P<0.05).The depletion of ETS1 significantly inhibited the proliferation of glioma cells and promoted cell apoptosis(P<0.05).ETS1 could target and bind with the XIST promoter and promote the expression of XIST(P<0.05).The overexpression of XIST reversed the effects of ETS1 on the proliferation of glioma cells and the promotion of cell apoptosis(P<0.05).Conclusion ETS1 is highly expressed in glioma tissues.It could promote the expression of lncRNA XIST,boost the proliferation of glioma cells,and inhibit cell apoptosis.

Objective To investigate the relationship between the changes of serum human surfactant pro-tein D(SP-D)and vascular cell adhesion molecule-1(sVCAM-1)levels and postoperative fracture healing and short-term prognosis in patients with traumatic rib fractures.Methods A total of 102 patients with traumatic rib fractures who were treated in Banan Hospital Affiliated to Chongqing Medical University from January 2020 to December 2021 were selected as the research objects.After 8 months of treatment,the healing status of the patients was analyzed and divided into non-healing group(21 cases)and healing group(81 cases).Ac-cording to the pulmonary contusion,the patients were divided into pulmonary contusion group(19 cases)and non-pulmonary contusion group(83 cases).The serum levels of SP-D and sVCAM-1 were compared between the healing group and the non-healing group,and between the pulmonary contusion group and the non-pulmo-nary contusion group.The relationship between the changes of serum SP-D and sVCAM-1 levels and postop-erative fracture healing and short-term prognosis in patients with traumatic rib fractures were studied.Results The levels of SP-D and sVCAM-1 in the healing group were lower than those in the non-healing group(P＜0.05).The levels of SP-D and sVCAM-1 in the non-pulmonary contusion group were lower than those in the pulmonary contusion group(P＜0.05).Serum SP-D and sVCAM-1 levels were independent risk factors for postoperative fracture healing and short-term prognosis.Conclusion The changes of serum SP-D and sVCAM-1 levels in patients with traumatic rib fractures are related to fracture healing and short-term prognosis,which can be used as an important reference for prognosis evaluation.

Objective:To evaluate the effects of Huoxue Bushen Formula Granules on endometrial receptivity (ER) in patients with polycystic ovary syndrome (PCOS) in ovulation induction cycle.Methods:A randomized controlled trial was conducted. Totally 50 patients with PCOS infertility in Xiyuan Hospital of China Academy of Chinese Medical Sciences from January 2019 to January 2023 were selected as the observation objects, and were divided into observation group (29 cases) and control group (21 cases) according to the random number table method. Both groups were given oral clomiphene citrate on the 5th day of menstrual cycle or progesterone withdrawal. On this basis, the observation group was given Huoxue Bushen Formula Granules on the 5th day of menstruation, while the control group was given estradiol valerate tablets. 7 days after taking medication and injecting hCG from the 10th day of menstruation, ovulation was monitored and sexual intercourse was guided. Both groups were treated for 3 menstrual cycles and followed up for 3 months. B-ultrasound was performed on 6-8 days after ovulation to obtain uterine artery pulsatility index (PI) and blood flow resistance index (RI). TCM syndrome scores were evaluated before and after treatment, and the endometrial receptivity score (Salle score) was used to evaluate the level of ER. The pregnancy and adverse reactions during treatment were recorded in the two groups.Results:After treatment, TCM syndrome score in the observation group [14.0 (13.0, 15.0) vs. 16.0 (14.5, 19.5), Z=-3.23] was lower than that of the control group ( P<0.001). The Salle score of the observation group after treatment [12.0 (9.5.0, 13.5) vs. 10.0 (9.0, 11.0), Z=-3.84] was higher than that before treatment ( P<0.001). The PI (0.68±0.52 vs. 0.81±0.06, t=18.25), RI (1.65±0.36 vs. 2.24±0.45, t=22.78) after treatment in the observation group and the control group were lower than those before treatment ( P<0.001), without statistical significance ( t values were -0.39, -1.37, respectively, P>0.05). The total effective rate of the observation group was 75.86% (22/29), and that of the control group was 71.43% (15/21), without statistical significance ( χ2=0.12, P=0.724). The pregnancy rate of the observation group was 82.76% (24/29), and that of the control group was 57.14% (12/21), with statistical significance ( χ2=3.96, P=0.046). The incidence of adverse reactions of the observation group was 3.45% (1/29) and that of the control group was 9.52% (2/21), without statistical significance ( χ2=0.80, P=0.372). Conclusion:Huoxue Bushen Formula Granules can improve the ER of PCOS infertility patients with kidney deficiency and blood stasis syndrome, improve the pregnancy rate, reduce the TCM syndrome score, improve the quality of life of patients with high safety.
