Objective:To compare the mid-term efficacy of one anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG) in the treatment of obesity and metabolic syndrome, and related postoperative complications.Method:Clinical data of patients undergoing indirect OAGB or SG from Jan to Dec 2022 was enrolled. Firty-eight patients were included in the OAGB group and 178 patients were included in the SG group. Propensity matching scores was performed with matching ratio of 1∶1. Eighty-four patients (42 in each group) were included in the analysis finally. We compared the differences in weight loss, metabolic syndrome remission, and postoperative complications among different groups.Result:The 2-year follow-up results show that the OAGB group and SG group showed similar improvements in weight, BMI, percentage of total weight loss, percentage of excess weight loss [(71.60±11.47)kg vs. (72.90±11.21)kg, t=0.529, P>0.05;(26.13±4.16)kg/m 2vs. (26.86±4.12)kg/m 2, t=0.805, P>0.05; (30.89%±9.68%) vs. (27.59%±7.74%), t=1.726, P>0.05; (99.25%± 36.35%) vs. (97.02%±40.97%), t=0.264, P>0.05]. In terms of metabolic complications, the OAGB group had a higher remission rate. The OAGB group showed more significant improvements in fasting plasma glucose, glycated Hemoglobin A1c, triglycerides, uric acid [(5.11±0.36)mmol/L vs. (5.40±0.63)mmol/L, t=2.593, P<0.05; (5.13%±0.4%) vs. (5.38%±0.36%), t=2.889, P<0.05; (0.94±0.35)mmol/L vs. (1.12±0.41)mmol/L, t=2.145, P<0.05; (330.60±73.73)μmol/L vs. (394.30±111.43)μmol/L, t=3.089, P<0.05]. There was no statistically significant difference in hemoglobin and albumin, but the serum iron in the OAGB group was lower than SG group, and the difference was statistically significant [(14.45±7.75)μmol/L vs.(17.78±6.58)μmol/L, t=2.118, P<0.05]. There was no difference between the two groups in terms of postoperative complications. Conclusion:OAGB has similar weight loss effects and postoperative complication rates compared to SG, and effectively improves metabolic symptoms.

Objective: To investigate the factors affecting postpartum stress urinary incontinence (PSUI) among lying-in women at ages of 35 years and older, so as to provide insights into PSUI prevention. Methods: Lying-in women at ages of 35 years and older receiving postpartum examinations were sampled using a convenient sampling method from Hangzhou Obstetrics and Gynecology Hospital during the period from January 2021 to April 2022. Participants' demographic data, type of delivery, birth weight, diastasis recti abdominis, pelvic floor muscle strength injury, pelvic floor muscle training were collected, and the development of PSUI was evaluated using the International Consultation on Incontinence modular questionnaire. The factors affecting the development of PSUI were identified among lying-in women at ages of 35 years and older using a multivariable logistic regression model. Results: A total of 230 questionnaires were allocated, and 226 valid questionnaires were recovered, with an effective recovery rate of 98.26%. The lying-in women had a mean age of (37.30±2.11) years, and 75.66% had a pre-pregnancy body mass index (BMI) of 18.5 to 24.0 kg/m2. There were 29 women with postpartum BMI of 24.0 kg/m2 and greater (12.83%), 201 women with gestational weeks of 37 weeks and greater at delivery (88.94%), 105 women with vaginal delivery (46.46%), 20 women with neonatal birth weights of 4 000 g and higher (8.85%), 149 women with diastasis recti abdominis (65.93%), 154 women with pelvic floor muscle strength injury (68.14%). The prevalence of PSUI was 25.22% among the study subjects. Multivariable logistic regression analysis showed that vaginal delivery (OR=4.061, 95%CI: 2.124-7.763), postpartum BMI of 24 kg/m2 and higher (OR=1.903, 95%CI: 1.275-3.288), neonatal birth weight of 4 000 g and higher (OR=2.108, 95%CI: 1.420-4.135), diastasis recti abdominis (OR=1.487, 95%CI: 1.110-2.169) and pelvic floor muscle strength injury (OR=2.924, 95%CI: 1.726-4.803) were risk factors for PSUI among lying-in women at ages of 35 years and older, and pelvic floor muscle training was a protective factor for PSUI among lying-in women at ages of 35 years and older (OR=0.410, 95%CI: 0.216-0.780). Conclusions The development of PSUI correlates with the type of delivery, postpartum BMI, neonatal birth weight, diastasis recti abdominis and pelvic floor muscle strength injury among lying-in women. Reasonable weight control and active pelvic floor muscle training may facilitate the prevention of PSUI.

OBJECTIVE: To determine the mass scores of naringin and neohesperidin in Fructus aurantii and Citrus chang-shan-huyou with their processed products and evaluate the quality of Fructus aurantii and Citrus changshan-huyou with their pro-cessed products. METHODS:According to the requirements of Chinese Pharmacopoeia(2010 edition)and Zhejiang Province Tradi-tional Chinese Medicine Preparation Standards (2005 edition),the moisture and ash of F. aurantii and C. changshan-huyou with their processed products were detected. And the contents of naringin and neohesperidin were determined. The ZORBAX SB-C18 column was used with the mobile phase of acetonitrile-water(20∶80,V/V)at the flow rate of 1.0 ml/min. The detection wave-length was set at 283 nm,and the column temperature was 40℃.The samples size was 10μl. RESULTS:The moisture of F. au-rantii and C. changshan-huyou was decreased after processing with no obvious change for ash. The contents of naringin and neohes-peridin were decreased,significantly for F. aurantii,and all consistent with the requirements of Chinese Pharmacopoeia(2010 edi-tion)except F. aurantii. The linear range was 0.028 45-0.284 5μg(r=0.999 7)for naringin and 0.085 9-0.858 6μg(r=0.999 6)for neohesperidin;the RSDs of precision,stability and reproducibility tests were no more than 1.36% and the average recovery was re-spectively 96.45%-100.43%(RSD=1.45%,n=6) and 98.36%-102.00%(RSD=1.26%,n=6). CONCLUSIONS: There was no significant difference in the inspection and determination re-sults in F. aurantii and C. changshan-huyou. It is suggested to adjust the limitation of content determination in the Chinese Pharmacopoeia(2010 edition)and processed standards.
