Objective To evaluate clinical and sexual outcomes in women with severe uterine prolapsed at child-bearing period undergoing laparoscopic high uterosacral ligament suspension combined with cervical amputation.Methods From November 2007 to March 2010,34 patients (≤50 years old) with severe uterine prolapse (prolapse group) who had already given birth and underwent laparoscopic high uterosacral ligament suspension combined with cervical amputation in Peking Union Medical College Hospital were enrolled in this retrospective study.All patients were defined as Pelvic Organ Prolapse Quantification (POP-Q) stage Ⅲ.Follow-up was performed at 1,6,and 12 months,and then annually.Anatomic failure was defined as ≥ 1 pelvic compartment classified as POP-Q ≥ stage Ⅱ.Sexual outcomes were assessed at baseline and 3-year follow-up according to validated Short-Form Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12).Thirty one age-matched women who underwent health examinations during the same time period were selected as a healthy control group.Results Mean age of women at prolapse group were (39 ±5) years and average surgery time were (51 ±8) minutes.No severe intraoperative complications occurred,including urethral twist,bladder and rectum injury,pelvic hemotoma.All patients were followed up for more than 3 years,the mean following up period was 40 months (36-64 months).Based on stage Ⅱ of POP-Q as recurrence criteria,the anatomical success and patient satisfaction rates were both 100％ (34/34).POP-Q point C and D measurements were significantly higher after surgery then those at preoperative values [C:(-5.4±0.6) cm versus (2.2 ±0.7) cm,D:(-6.7 ±0.4) cm versus (-4.0 ±0.7) cm; P ＜0.01 for all].Three years postoperatively,33 patients were sexually active.Among the 94％ (31/33) patients who answered the PISQ-12 questionnaire,there was significant improvement in post-and preoperative total PISQ-12 scores (38 versus 26,P ＜ 0.01) and in all three subscale PISQ-12 domains (P ＜ 0.01 for all).The postoperative PISQ-12 score was similar to that of the control group (38 ± 6 versus 37 ± 3,P ＞ 0.05).Conclusion Laparoscopic high uterosacral ligament suspension combined with cervical amputation conferred satisfying long-term anatomic and sexual function outcomes in women at child-bearing age.

Objective:To analyze the difference and reliability of blood 17-hydroxyprogesterone (17-OHP), an indirect screening index for congenital adrenal hyperplasia (CAH), between preterm and full-term infants.Methods:In this retrospective cross-sectional study, a total of 210 285 newborns who underwent CAH screening at the Neonatal Screening Center of Shanghai Children′s Hospital from January 2019 to December 2022 were collected, including 14 312 premature infants and 195 973 full-term infants.The concentration of 17-OHP in dried blood spots on filter paper was determined by an automatic fluorescence analyzer.The distribution of 17-OHP levels in preterm and full-term infants and its statistical index were analyzed.The Kolmogorov-Smirnov test was used for normal distribution.The skewed distribution data was converted into approximately normal distribution using Box-Cox.Outliers were eliminated by the interquartile range method.The cumulative frequency distribution map was drawn by R language programming.The 99.5 th percentile value was used as the screening threshold and compared with the reference value given by the manufacturer or laboratory and with the reference change value (RCV). Results:According to the threshold provided by the laboratory, 26.76‰ of premature infants were tested positive in preliminary screening, and 4 were confirmed with an incidence of 1∶3 578, while 0.79‰ of full-term infants were tested positive in preliminary screening, and 11 were confirmed with an incidence of 1∶17 816.The thresholds for CAH screening established indirectly were 20.35 nmol/L in preterm infants and 10.78 nmol/L in full-term infants.The relative deviations between the indirect CAH screening thresholds and the manufacturer′s or laboratory′s CAH screening thresholds were higher than the RCV, respectively.According to the indirect CAH screening thresholds, the negative and positive coincidence rates of 65 samples in 13 batches from the Centers for Disease Control and Prevention interlaboratory quality assessment program in the United States reached 100%.A retrospective analysis of 210 285 neonates showed that 17-OHP concentration was higher than the screening threshold in all CAH-positive neonates.The application of this screening threshold reduced the false positive rate of preterm infants by 59.79%.Conclusions:It is feasible to establish the CAH screening thresholds for premature and full-term infants by an indirect method, which can improve the efficiency of screening and provide better diagnostic basis for clinical practice.

ObjectiveTo observe the intervention effect of Ruyi Zhenbao pills （RYZBP） on central pain after thalamic stroke in mice and explore the underlying mechanism. MethodThe central post-stroke pain syndrome （CPSP） model was induced by stereotactic injection of type Ⅳ collagenase into the hypothalamus in mice. The mice were divided into a sham group， a model group， low-， medium-， and high-dose RYZBP groups （0.65， 1.3， 2.6 g·kg^-1）， and a pregabalin group （0.075 g·kg^-1）. Seven days after modeling， the mice in the groups with drug intervention were administered with corresponding drugs by gavage according to the body mass， once per day for 25 days， while those in the sham group and the model group received an equal volume of normal saline. During this period， mechanical pain and cold pain were detected at different time points， and the apoptotic state of brain tissue cells was detected by in situ terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling （TUNEL）. The 36 classical broad-spectrum inflammatory factors were quantitatively analyzed by liquid-phase chip technology， and differential molecules were screened out and verified by Western blot and enzyme-linked immunosorbent assay （ELISA）. ResultCompared with sham operation group, mechanical pain threshold and cold sensitive pain threshold in model group were significantly changed （P<0.01）. TUNEL results showed that apoptosis of brain cells was obvious. Western blot and ELISA results showed that the expressions of interleukin-1α (IL-1α) and chemokine ligand 5 (CCL5) increased in hypothalamus tissue and serum， while the expressions of Ang-2, granulocyte-colony-stimulating factor (G-CSF) and IL-4 decreased significantly （P<0.01）. Compared with model group， RYZBW dose groups significantly increased mechanical pain threshold， decreased cold sensitivity pain threshold， decreased hypothalamus cell apoptosis ratio （P<0.01）， decreased the expression of IL-1α and CCL5 in hypothalamus tissue and serum， while the expression of ANG-2， G-CSF and IL-4 were significantly increased （P<0.05）. ConclusionRYZBP can relieve hyperalgesia in CPSP mice， and its mechanism is related to the regulation of the expression of pro-/anti-inflammatory factors IL-1α， CCL5， IL-4， G-CSF， and Ang-2.
