Objective: To investigate the association between plant-based dietary patterns and gestational weight gain (GWG) among pregnant women with gestational diabetes mellitus (GDM), so as to provide the evidence for guiding the reasonable diet during pregnancy. Methods: GDM pregnant women who participated in the WeBirth project in Hangzhou Obstetrics and Gynecology Hospital were selected. Maternal age and pre-pregnancy body mass index (BMI) were collected. The Chinese version of Pregnancy Physical Activity questionnaire was used to assess the daily activity equivalent. The food frequency questionnaire was used to collect the frequency and amount of food intake in the last month before enrollment. The overall plant-based diet index (PDI), healthy plant-based diet index (HPDI), and unhealthy plant-based diet index (UPDI) were constructed based on food intake and grouped by quartiles. Multiple linear regression models were used to analyze the association between plant-based dietary patterns and GWG. Results: A total of 1 943 pregnant women with GDM, with a median age of 30.91 (interquartile range, 4.92) years. The median BMI of pre-pregnancy was 21.51 (interquartile range, 4.06) kg/m2. The medians of PDI, HPDI and UPDI were 32.42 (interquartile range, 4.60), 32.48 (interquartile range, 4.41) and 32.40 (interquartile range, 5.36), respectively. The median of GWG was 11.30 (interquartile range, 4.52) kg. Multiple linear regression analysis showed that PDI (Q3 group, β=0.674, 95%CI: 0.064-1.285; Q4 group, β=0.702, 95%CI: 0.098-1.306), UPDI (Q3 group, β=1.332, 95%CI: 0.771-1.894; Q4 group, β=1.115, 95%CI: 0.550-1.681) were positively associated with GWG after adjusting for age, pre-pregnancy BMI, daily activity equivalent and daily energy intake. No significant association was found between HPDI and GWG (all P>0.05). Conclusion UPDI was associated with a higher risk of GWG in pregnant women with GDM.

OBJECTIVES: Near vision loss (NVL) is one of the leading causes of visual impairment worldwide, exerting a profound impact on individual quality of life and socio-economic development. This study aims to analyze the burden of NVL in China by sex and age groups from 1990 to 2021 and to project trends over the next 15 years. METHODS: Using data from the Global Burden of Disease (GBD) 2021 database, we conducted descriptive analyses of NVL prevalence in China, calculated age-standardized prevalence rates (ASPR) and age-standardized disability-adjusted life years rates (ASDR) to compare burden differences between sexes and age groups, and applied an autoregressive integrated moving average (ARIMA) model to predict NVL trends for the next 15 years. The model selection was based on best-fit criteria to ensure reliable projections. RESULTS: From 1990 to 2021, China's ASPR of NVL rose from 10 096.24/100 000 to 15 624.54/100 000, and ASDR increased from 101.75/100 000 to 158.75/100 000. In 2021, ASPR (16 551.70/100 000) and ASDR (167.69/100 000) were higher among females than males (14 686.21/100 000 and 149.76/100 000, respectively). China ranked highest globally in both NVL cases and disability-adjusted life years (DALYs), with female burden significantly exceeding male burden. Projections indicated this trend and sex gap will persist until 2036. Compared with 1990, the prevalence cases and DALYs increased by 239.20% and 238.82%, respectively in 2021, with the highest burden among females and the 55-59 age group. The ARIMA model predicted continued increases in prevalence and DALYs by 2036, with females maintaining a higher burden than males. CONCLUSIONS This study reveals a marked increase in the NVL burden in China and predicts continued growth in the coming years. Public health policies should prioritize NVL prevention and control, with special attention to women and middle-aged populations to mitigate long-term societal and health impacts.

OBJECTIVES: Pelvic floor sensory training is commonly used in clinical practice for the treatment of stress urinary incontinence (SUI); however, there is a lack of comparative studies evaluating pelvic floor sensation between women with SUI and healthy controls. Additionally, normative data for two-point discrimination thresholds in the female pelvic floor region remain scarce. This study aims to compare the results of 4 sensory tests in the pelvic floor region between women with mild SUI and healthy women, in order to provide reference values for two-point discrimination thresholds in this area. METHODS: From April 1 to October 30, 2023, 108 healthy women [(32.5±3.6) years] and 90 women with mild SUI [(32.9±3.3) years] were recruited from the Third Xiangya Hospital, Central South University. Participants underwent 4 sensory tests in the pelvic floor region: Two-dot discrimination, weight perception, shape recognition, and 9-grid localization. The results were compared between the 2 groups. RESULTS: Compared with healthy women, those with mild SUI had lower sensitivity and higher thresholds in 2-dot discrimination tests in the pelvic floor region (all P<0.001). No significant differences were found between groups in weight perception, shape recognition, or grid localization tests (P>0.05). CONCLUSIONS Women with mild stress urinary incontinence have impaired two-point discrimination ability in the pelvic floor region.

Objective:To compare the efficacy of closed-loop target-controlled deep versus moderate neuromuscular blockade in gynecological laparoscopic surgery.Methods:This was a prospective study. Fifty American Society of Anesthesiologists Physical Status classification I or Ⅱ patients, aged 18-64 yr, with body mass index of 18-30 kg/m 2, scheduled for elective gynecological laparoscopic surgery in the General Hospital of Tianjin Medical University from March 2020 to March 2021, were allocated into 2 groups ( n=25 each) using a random number table method: closed-loop target-controlled moderate neuromuscular blockade group (group TOF) and closed-loop target-controlled deep neuromuscular blockade group (group PTC). Rocuronium was given by closed-loop target-controlled infusion in both groups. In group TOF, the target muscle relaxation was considered as train-of-four stimulation (TOF) of 1 or 2. In group PTC, the target muscle relaxation was considered as post-titanic count of 1 or 2. The score for operator′s satisfaction with muscle relaxation, grading, satisfaction rate, mean pneumo-peritoneum pressure, consumption of rocuronium, recovery index, recovery time to a TOF ratio 0.9 and time to extubation were recorded. The postoperative visual analogue scale score for abdominal pain and use of rescue analgesics were recorded, and the occurrence of complications such as shoulder pain, arm pain, nausea, vomiting and hypoxemia was also recorded within 48 h after surgery. Results:Compared with group TOF, the score for operator′s satisfaction with muscle relaxation, grading and satisfaction rate were significantly increased, the mean pneumo-peritoneum pressure was decreased, the total and average consumption of rocuronium was increased, the recovery time of a TOF ratio 0.9 was prolonged, and the postoperative visual analogue scale score for abdominal pain and usage rate of flurbiprofenate were decreased in group PTC ( P<0.05). There were no significant differences in the recovery index, tracheal extubation time or postoperative incidence of hypoxemia, shoulder pain, arm pain and nausea and vomiting between the two groups ( P>0.05). Conclusions:Compared with the closed-loop target-controlled moderate neuromuscular blockade, the closed-loop target-controlled deep neuromuscular blockade provides more satisfactory surgical conditions for gynecological laparoscopic surgery, decreases pneumoperitoneum pressure and reduces related complications, without increasing the development of postoperative adverse reactions.

Objective:To comprehensively search the relevant literature on prone position-cardiopulmonary resuscitation (PP-CPR) in adults at home and abroad, analyze the content, summarize the evidence, and provide reference for clinical health care professionals.Methods:Systematic search of CNKI, China Biomedical Literature Service System (SinoMed), Wanfang Data, VIP database, PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochran Library, Web of Science, Scopus literature database and other Chinese and English databases was conducted. The search period was from inception to June 15 in 2024. The contents of PP-CPR from randomized controlled trial (RCT), non-RCT (prospective or retrospective), cohort studies and case reports were extracted and systematically analyzed. The search results were standardized by the method of scoping review.Results:A total of 523 articles were obtained through preliminary search, and 14 references and gray literature were retrieved, totaling 537 articles. After strict screening by two researchers, a total of 26 literatures were included, 3 were non-RCT and 23 were case reports, involving 12 countries, including 3 in Chinese, 19 in English, 2 in French, 1 in German, and 1 in Korean. Three non-RCT demonstrated that compared with standard cardiopulmonary resuscitation (CPR), PP-CPR could produce higher pressure, and provide good respiratory and circulatory support. A total of 25 adult patients were included in the 23 case reports, of which 17 reported total recovery time and 13 reported PP-CPR time ≤ 5 minutes, all of which recovered spontaneous circulation, indicating the effectiveness of PP-CPR technology. In terms of final outcome, 4 patients (16.0%) died and 21 patients (84.0%) survived, indicating that PP-CPR technology could provide timely blood circulation and improve clinical outcomes for prone cardiac arrest patients. Among the 11 patients who reported complications after resuscitation, no neurological damage was found in the short-term outcomes, indicating that PP-CPR technology had a certain level of safety.Conclusions:PP-CPR can provide timely blood circulation for patients with cardiac arrest who are unable to lie supine quickly, and win "golden time" for defibrillation and further treatment. In clinical practice, medical staff need to evaluate the emergency environment, the number of rescuers and the specific condition of the patient, and implement first aid as soon as possible, so as to reduce the time of no blood flow in the vital organs of patients with cardiac arrest in prone position, and improve the clinical prognosis.
