Pelvic organ prolapse (POP), whose etiology is influenced by genetic and clinical risk factors, considerably impacts women's quality of life. However, the genetic underpinnings in non-European populations and comprehensive risk models integrating genetic and clinical factors remain underexplored. This study constructed the first polygenic risk score (PRS) for POP in the Chinese population by utilizing 20 disease-associated variants from the largest existing genome-wide association study. We analyzed a discovery cohort of 576 cases and 623 controls and a validation cohort of 264 cases and 200 controls. Results showed that the case group exhibited a significantly higher PRS than the control group. Moreover, the odds ratio of the top 10% risk group was 2.6 times higher than that of the bottom 10%. A high PRS was significantly correlated with POP occurrence in women older than 50 years old and in those with one or no childbirths. As far as we know, the integrated prediction model, which combined PRS and clinical risk factors, demonstrated better predictive accuracy than other existing PRS models. This combined risk assessment model serves as a robust tool for POP risk prediction and stratification, thereby offering insights into individualized preventive measures and treatment strategies in future clinical practice.

Objective:To investigate the diagnostic value of ultrasonic measurement of optic nerve sheath diameter (ONSD) and optical disk elevation (ODE) for intracranial hypertension in patients with cerebral venous sinus thrombosis(CVST).Methods:A total of 50 patients with CVST who underwent lumbar puncture and ONSD examination in the Department of Neurology and Emergency Department of Xuanwu Hospital, Capital Medical University from January 2021 to December 2021 were retrospectively enrolled. After lumbar puncture, the patient′s initial intracranial pressure was recorded. Normal ICP was defined as ICP between 80 and 200 mmH 2O, and increased ICP was defined as ICP>200 mmH 2O. Fifty patients with CVST were divided into normal ICP group (14 cases) and increased ICP group (36 cases). The differences of baseline data, ONSD and ODE between the two groups were compared, and the receiver operating characteristic (ROC) curve was generated. The area under the curve (AUC) and the diagnostic cut-off value of ONSD were analyzed. Spearman correlation analysis was used to analyze the correlation between ONSD, ODE, CVST involvement range scores and intracranial pressure. Results:①There were no significant differences in gender, age and body mass index between the normal ICP group and the increased ICP group (all P>0.05). ②The ONSD and ODE in the increased ICP group were higher than those in the normal ICP group, and the differences were statistically significant [(4.83±0.33)mm vs (4.21±0.21)mm, (0.67±0.44)mm vs (0.24±0.29)mm, all P<0.001]. Spearman correlation analysis showed that ONSD and ODE were positively correlated with intracranial pressure ( rs=0.74, 0.51, all P<0.001). ③The extent of CVST involvement in the intracranial hypertension group was higher than that in the normal intracranial pressure group, and the difference was statistically significant [5.0(3.0, 7.5) vs 2.5(2.0, 5.0), P=0.015]. Spearman correlation analysis showed that CVST involvement score was positively correlated with intracranial pressure ( rs=0.43, P<0.001). ④In the diagnosis of intracranial hypertension in patients with cerebral venous sinus thrombosis, the AUC of ONSD was 0.935, the best diagnostic threshold of ONSD was 4.5 mm, the sensitivity was 0.81, and the specificity was 0.93. Conclusions:ONSD and ODE measured by ultrasound are reliable imaging methods to identify intracranial hypertension in patients with CVST.

BACKGROUND:Neural stem cels have the potential to differentiate into neurons and glial cels to replace the injured brain cels, so as to achieve the purpose of repairing nerve injury.
OBJECTIVE:To observe the neuronal differentiation ability of cel subsets with stem cel characteristics in the adult rat meningeal tissues.
METHODS:Under anesthesia, the meningeal tissues were obtained from adult Sprague-Dawley rats to make cel suspension folowed by inoculation and subculture. Then, the Nestin immunofluorescence staining was performed. The third generation cels were culturedin vitro with complete culture medium containing trichostatin A. After 7 days of induction, western blot assay was used to detect the expression of NF-200 and BM88 proteins in neural cels.
RESULTS AND CONCLUSION: At 24 hours of culture, some spherical cels were suspended and some cels adherent. In addition, some spherical cels scattered gradualy formed the clone spheres, and the growth rate decreased with the increasing volume. The positive expression of Nestin was detected by immunocytochemistry staining, and the cel nucleus was stained blue by Hoechst staining. BM88 and NF-200 proteins were al expressed at 7 days of neural induction. These findings indicate that the cel subsets with stem cel characteristics in the adult rat meningeal tissues can differentiate into neurons after in vitro induction.
