Objective:To investigate the factors that affect pelvic floor muscle repair in postpartum women.Methods:The clinical data of 100 patients who gave birth at the Third Affiliated Hospital of Xi'an Medical University between January 2021 and January 2024 and underwent pelvic floor muscle repair were analyzed retrospectively. Based on whether they received the repair, the patients were divided into a repair group ( n = 70) and a non-repair group ( n = 30). The clinical data of both groups were compared. Multivariate logistic regression was performed to analyze the main factors that influence postpartum pelvic floor muscle repair. A predictive model was constructed, and its predictive value for the effectiveness of postpartum pelvic floor muscle repair was evaluated using the receiver operating characteristic curve. Results:After pelvic floor muscle repair, total effective rate was 70% (70/100). There were significant differences between the repair group and the non-repair group in terms of age, parity, number of pregnancies, prenatal body mass index (BMI), neonatal body weight, mode of pelvic floor muscle repair, delivery mode, relaxin level, elastin level, pelvic floor muscle strength classification, degree of stress urinary incontinence, and training compliance (all P < 0.05). Multivariate analysis results indicated that age, prenatal BMI, parity, number of pregnancies, neonatal body weight, pelvic floor muscle strength grading, training compliance, relaxin level, and elastin level were independent influential factors for the effectiveness of postpartum pelvic floor muscle repair. The model can be represented as: Y = 1.253 × age + 0.131 × prenatal BMI + 1.313 × parity + 2.603 × number of pregnancies + 0.559 × neonatal body weight -1.512 × pelvic floor muscle strength grading + 1.271 × training compliance + 0.404 × relaxin level -9.945 × elastin level -4.015. The receiver operating characteristic curve results showed that the area under the curve values for age, prenatal BMI, parity, number of pregnancies, neonatal body weight, pelvic floor muscle strength grading, training compliance, relaxin level, and elastin level in predicting the effectiveness of postpartum pelvic floor muscle repair were 0.650, 0.634, 0.657, 0.786, 0.610, 0.783, 0.645, 0.949, and 0.991, respectively. The area under the curve values for relaxin and elastin levels exceeded 0.9, with the corresponding sensitivity and specificity for relaxin level being 90.00% and 92.90%, respectively, and for elastin level being 100.00% and 95.70%, respectively. Conclusions:Age, prenatal BMI, parity, number of pregnancies, neonatal body weight, pelvic floor muscle strength grading, training compliance, relaxin level, and elastin level are factors that affect the effectiveness of postpartum pelvic floor muscle repair. These factors have certain predictive value for the effectiveness of pelvic floor muscle repair, with relaxin and elastin levels showing particularly high predictive value. Clinically, this information can be used to develop a reasonable pelvic floor muscle repair plan for postpartum women.

Objective:To investigate the clinical features, diagnosis, treatment, and future sex selection in patients with partial androgen insensitivity syndrome (PAIS).Methods:Retrospective analysis of clinical data of three patients with PAIS who received treatment in The Third Affiliated Hospital of Xi'an Medical University, Beijing Ditan Hospital of Capital Medical University, and Beijing Yayuncun Amcare Women's and Children's Hospital from 2013 to 2015 was conducted. Physical signs, specialized examinations, surgical explorations, and treatments were analyzed. The Chinese database was searched, and 12 cases of PAIS were collected and summarized.Results:Fifteen patients with PAIS presented with primary amenorrhea (15/15). Special clinical manifestations included gender as male or appearing as male (5/15), penile dysplasia or clitoral hypertrophy (14/15), urethral dysplasia (5/15), and breast development (4/15). Eleven cases were treated based on female gender (including surgery and hormone replacement therapy). There were three special patients with PAIS who had specific etiology, genetics, clinical manifestations, histopathology, diagnosis, and treatment and ultimately underwent treatment based on female gender.Conclusion:PAIS is a rare form of disorder of sex development, featuring a karyotype of 46, XY, and is a congenital X-linked recessive condition. Understanding the pathogenesis of PAIS more thoroughly can contribute to accurate diagnosis, personalized treatment, and well-organized follow-up, thereby preventing gender dysphoria.

OBJECTIVE:To investigate the effects of TanshinoneⅡA sodium sulfonate injection on levels of P-selectin,glial fi-brillary acidic protein (GFAP),vascular endothelial growth factor (VEGF) and neurological function in patients with acute cere-bral infarction. METHODS:A total of 114 patients with acute cerebral infarction selected from Lianyungang First People's Hospi-tal during Apr. 2013-Apr. 2016 were divided into control group and observation group according to random number table,with 57 cases in each group. Control group was given routine treatment. Observation group was additionally given Tanshinone ⅡA sodium sulfonate injection 40 mg 0.9％ sodium chlonride injection 250 mL,ivgtt,qd. A treatment course lasted for 7 d,and both received 2 courses of treatment. NIHSS scores,the levels of serum P-selectin,GFAP and VEGF were compared between 2 groups before treatment and after 7,14 d of treatment. The occurrence of ADR was also compared. RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups(P>0.05). Compared to before treatment,NIHSS score,the levels of se-rum P-selectin and GFAP in 2 groups were decreased significantly after 7,14 d of treatment,while the serum level of VEGF was increased significantly. These indexes of 2 groups after 14 d of treatment were significantly better than 7 d of treatment,except for NIHSS score. Above indexes of observation group was significantly better than those of control group during corresponding period, with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:For acute cerebral infarction, Tanshinone ⅡA sodium sulfonate injection can significantly reduce the levels of serum P-selectin and GFAP,improve VEGF level and promote the recovery of neurological damage with good safety.
