Objective To quantify the association between obesity and erectile dysfunction (ED) risk through a meta-analysis. Methods Following PRISMA guidelines, systematic searches of Chinese and English databases (up to March 2025) were conducted to include observational studies (cohort, cross-sectional, case-control). Adjusted effect sizes (OR and 95% CI) were extracted. Study quality was assessed using the Agency for Healthcare Research and Quality(AHRQ) scale, and a random-effects model was applied to pool effect sizes. Subgroup analyses (geographic region, obesity definitions) and sensitivity analyses were performed to validate robustness. Results Ten studies (n=230 744), including nine cross-sectional studies, were included. The meta-analysis revealed that obesity significantly increased ED risk (random-effects OR=1.80, 95% CI: 1.29-2.51), with high heterogeneity (I2=99.9%). Subgroup analyses indicated stronger associations in USA populations (OR=2.10, 95% CI: 1.23-3.60) than in Chinese populations (OR=1.16, 95% CI: 1.05-1.28). The highest effect size was observed when using BMI≥25 kg/m3 as the obesity threshold (OR=3.05, 95% CI: 2.06-4.51). Sensitivity analyses confirmed robust results (OR: 1.60-1.94 after excluding any single study). Conclusions Obesity is a critical risk factor for ED, with effect strength influenced by geographic region and obesity definitions. Interventions targeting BMI≥30 kg/m2 in Western populations and metabolic risks at BMI≥25 kg/m3 in Asian populations are recommended.

AIM: To analyze the corneal morphological characteristics of school-age children, and provide reference for the examination of refractive errors, corneal lesions, and treatment in school-age children.METHODS: Children aged 6-12 years in our hospital from March 2020 to June 2023 were included as the research objects, and they are divided into emmetropia group(-0.25 D≤SE≤+0.25 D)and myopia group(-6.00 D≤SE<-0.25 D)according to spherical equivalent(SE). The flat curvature(K1), steep curvature(K2), mean curvature(Km), radius of curvature(Rm), white-to-white(WTW)and corneal central thickness(CCT)were measured by Pentacam anterior segment analyzer. The corneal morphological differences between the emmetropia group and myopia group, boys and girls and children of different ages were analyzed.RESULTS: In the emmetropia group, the anterior corneal surface Km was 42.84±0.61 D, Rm was 7.85±0.15 mm, the posterior corneal surface Km was -6.23±0.04 D, Rm was 6.77±0.15 mm, WTW was 11.89±0.28 mm, CCT was 557.77±22.44 μm; in the myopia group, Km was 43.68±0.62 D, Rm was 7.72±0.16 mm, Km was -6.49±0.03 D, Rm was 6.64±0.17 mm, WTW was 12.17±0.27 mm, CCT was 553.24±22.23 μm. There was significant difference in corneal morphology between the emmetropia group and the myopia group(both P<0.01). Correlation analysis showed that corneal morphology was significantly correlated with age and gender.CONCLUSION: The corneal morphology of school-age children is not fixed, and the occurrence of myopia is not only related to the growth of axial length, but also significantly related to the changes of corneal morphology.

ObjectiveTo explore the suitability of four qualitative research methods in the development of TCM scale. MethodsTaking the development of "Seven Emotions Scale" as an example, we conducted semi-structured interviews with 31 patients of emotional disorders and 10 healthy people by objective sampling, and collected psychological feelings and emotional cognition data related to seven emotions according to the interview outline. Two qualitative methods, descriptive qualitative research and descriptive phenomenology, were used to analyze the data and construct the item library of the scale. The conceptual framework of the scale was constructed by using commonly used grounded theory and frame analysis. ResultsDuring data analysis, it is found that the themes extracted from descriptive phenomenology were not easily understood by the interviewees, and it is difficult for the researchers to truly achieve the "suspension" required by phenomenology. Considering the feasibility and convenience of the researchers' actual operation, as well as whether the initial purpose of the scale research can be intuitively included in the interviewees' views and feelings, descriptive phenomenology is not suitable for the formation of scale items. Using descriptive qualitative research method to analyze the interview data of healthy people and patients with emotional disorders, 306 and 476 scale items were obtained respectively. Through grounded theory, five selective codes were obtained: physical symptoms, external manifestations, psychological feelings, behaviors and emotional control. Using frame analysis, four themes including physical symptoms, psychological feelings, behavior and emotional cognition were constructed. Both methods can be used to construct the conceptual frame of scale, but the framework analysis is more convenient and can better ensure the transparency of the research. ConclusionDescriptive qualitative research methods can be used to form the item library of TCM scales. Framework analysis is more suitable for the construction of the conceptual framework of the scale than grounded theory, while descriptive phenomenology is not suitable for the development of TCM scales.

This article summarizes and organizes relevant publications in journals, along with a review of medical history, systematically summarizing the development process of dental alveolar surgery in China. The initial establishment phase (1935—1952) marked the starting point of Chinese Alveolar Surgery. Despite the impact of wars, it laid the foundation for subsequent research and practice. During the early development phase (1953—1966), the "Chinese Journal of Stomatology" was founded, which promoted the development of Alveolar Surgery. Research focused on tooth extraction methods and complications. Tooth Transplantation and Preprosthetic Surgery gradually began to take off. The stagnant phase (1967—1977) occurred due to the interruption of international exchanges, leading to an almost complete halt in the development of Alveolar Surgery. Entering the rapid catch-up phase (1978—1985), Alveolar Surgery scholars in China began striving to overcome the stagnation of the previous decade. While some progress was made, no significant innovative achievements emerged. In the scientific development phase (1986—2010), clinical research, basic experiments, and paper writing in modern Chinese Alveolar Surgery began to adhere to scientific standards with the rise of experimental medicine. The exploration and innovation stage (2011—2023) is the current development phase, during which Chinese Aveolar Surgery has reached its peak, making substantial progress in technology, clinical practices, and basic research, gradually reaching or even surpassing international advanced levels. Looking back at the development history in China, we can find the wisdom and hard work of the older generation of Alveolar Surgery scholars. However, contemporary challenges and issues, such as standardizing technology, promoting clinical practices, and talent cultivation, need to be addressed by present-day Alveolar Surgery professionals as they forge ahead.

Journal of Gynecologic Oncology 2024;35(5):e99-
Objective:
First-line bevacizumab plus carboplatin and paclitaxel (CP) is approved for stage III/IV ovarian cancer treatment following initial surgical resection, based on global phase III GOG-0218 and ICON7 trials. This study evaluated the efficacy and safety of bevacizumab + CP as first-line ovarian cancer therapy in Chinese patients.
Methods:
Patients with newly diagnosed, International Federation of Gynecology and Obstetrics (FIGO) stage III/IV epithelial ovarian, fallopian tube, or primary peritoneal cancer post-primary surgery were randomized 1:1 to receive 6 cycles of CP with bevacizumab/ placebo, followed by bevacizumab/placebo maintenance until unacceptable toxicity or disease progression. Primary endpoint was investigator-assessed progression-free survival (PFS). Stratification factors were FIGO stage and debulking status (stage III optimally debulked vs stage III suboptimally debulked vs stage IV) and Eastern Cooperative Oncology Group performance status (0 vs 1 or 2).
Results:
Of randomized patients, 51 received bevacizumab + CP and 49 received placebo + CP. Median PFS was 22.6 months with bevacizumab + CP (95% confidence interval [CI]=18.6, not estimable) and 12.3 months (95% CI=9.5, 15.0) with placebo + CP (stratified hazard ratio=0.30; 95% CI=0.17, 0.53). Treatment-related grade 3/4 adverse events occurred in 46 of 49 (94%) patients receiving bevacizumab + CP, and 34 of 50 (68%) receiving placebo + CP.
Conclusion
Bevacizumab + CP showed clinically meaningful improvement in PFS vs placebo + CP, consistent with GOG-0218 results. Safety data were aligned with the known bevacizumab safety profile. These results support first-line bevacizumab + CP therapy in Chinese patients with ovarian cancer.
