Objective:To evaluate the feasibility of pelvic floor muscle reconstruction for women with vaginal laxity accompanied by stress urinary incontinence (SUI).Methods:A prospective cohort clinical study was conducted to collect clinical data from patients with vaginal laxity and SUI admitted to the Urogenital Reconstructive and Gender-affirming Department at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences, and the Department of Urology, Third Medical Center, Chinese PLA General Hospital, from January 2019 to September 2022. Patients underwent surgical treatment for pelvic floor muscle reconstruction. The cough provocation test and the patient global impression of improvement (PGI-I) scale were utilized as objective and subjective indicators of treatment effecacy, respectively. The urinary incontinence quality of life scale (I-QOL) and the pelvic organ prolapse and urinary incontinence sexual function questionnaire 12(PISQ-12) were used to evaluate the changes in quality of life and sexual funtion. The changes in pelvic floor anatomical structure were evaluated by pelvic floor ultrasound. Data analysis was performed using SPSS version 23.0. The I-QOL and PISQ-12 scores, posterior vesicourethral angle, urethral rotation angle, and bladder neck motion before and after surgery were analyzed using paired t-test, with P<0.05 was considered statistically significant. Results:A total of 36 female patients were included, with an average age of 41.7 years (ranged 24-51 years) and an average body mass index of 23.8 kg/m 2. The average operation time was 76.2 minutes, and the average blood loss was 84.5 milliliters. After 12-27 months of postoperative follow-up, the objective and subjective cure rates were 86.1% (31/36) and 88.9% (32/36), respectively. The sexual function and quality of life of the patients were significantly improved compared with the preoperative results, and postoperative pelvic floor ultrasound results showed significant improvement. The I-QOL and PISQ-12 scores 12 months after surgery were statistically significant compared with those before surgery ( P<0.01). Postoperative pelvic floor ultrasonography revealed statistically significant differences in posterior vesicourethral angle, urethral rotation angle, and bladder neck motion during maximum Valsalva maneuver compared to preoperative data ( P<0.01). Conclusion:Pelvic floor muscle reconstruction is a safe and effective surgical method for patients with vaginal laxity combined with SUI. This procedure can significantly improve sexual quality of life and alleviates SUI symptoms, restores anatomical structure in the female pelvic floor, and enhances overall quality of life.

Schizophrenia is a serious mental disorder that is often associated with profound impairment in patients′ daily functioning, and its etiology and pathophysiology are still to be fully elucidated. There is a pathological correlation between inflammation, brain injuries, and the pathogenesis of schizophrenia, with microglia actively participating in these processes. This review provides a comprehensive overview of the impact of microglial cells on neurodevelopment and neuroplasticity, and microglia abnormalities mediating the onset of schizophrenia by contributing to damage in different brain regions.

ObjectiveTo identify the rate， population characteristics， and vaccination history of repeat infections among previously infected people in the current epidemic based on the rate of repeat infection and population characteristics of different mutant strains at different times in Pudong New Area of Shanghai， and to provide reference for the prevention and control strategies of novel coronavirus repeat infections. MethodsA total of 9 250 investigated subjects were randomly selected from the new cases of asymptomatic infection and confirmed cases reported by Pudong New Area from March to May 2022. The investigation mainly focused on demographic characteristics， nucleic acid or antigen test results， and symptoms after infection. The repeat infection rates among different populations were compared， and logistic regression was used to analyze the impact of gender， age， and vaccination status on repeat infections. ResultsThe survey sample of 9 250 people had a response rate of 81.85%. There were 4 043 males （53.40%） and 3 528 females （46.60%）， with a median age of 34 years old （P₂₅， P₇₅： 7， 61）. The overall vaccine uptake rate was 59.44% （4 500/7 571）. In December of 2022， there were 563 cases of repeat infection， with an infection rate of 7.44%. The lowest rate of repeat infection was seen in the 3‒ year-old group （2.86%） and the highest rate in the 30‒ year-old group （12.42%）， with significant differences between different age groups. The repeated infection rate for those who had completed their vaccinations was significantly lower （6.57%） compared to those who had not （7.11%）. The age groups of 3‒ years， 70‒79 years， as well as individuals who completed full vaccination and received booster shots were protective factors against repeat infections. ConclusionThe overall rate of reinfection among the infected in Shanghai during the spring of 2022 was low in the outbreak of the Omicron variant， and the rate of reinfection in the 3‒ year-old group was significantly lower than in other age groups. Completing the full course of vaccination significantly reduces the risk of reinfection. Although the reinfection rate is high in individuals who received booster shots， it remains a mitigating factor compared to those who do not receive the vaccine. It is recommended to continue monitoring reinfections in key populations and further strengthen immunization efforts.

ObjectiveTo investigate the mechanisms of Panax notoginseng saponins （PNS） in inhibiting high shear-induced platelet aggregation and thrombosis via the Piezo1-mediated calcium signaling pathway. MethodBioflux1000z was used for the microfluidic assay， where platelets were stimulated with physiological shear rate （500 s^-1）， pathological shear rate （12 000 s^-1）， or Piezo1 agonist Yoda1 under the physiological shear rate （500 s^-1）. The shear-induced platelet calcium influx and the binding of platelet with von Willebrand factor （vWF） were measured by flow cytometry. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the vWF release from platelets. The microfluidic channels were used to determine the vWF-mediated platelet aggregation and integrin αⅡbβ3 activation. A mouse model of arterial thrombosis induced by high shear stress combined with endothelial injury was established. The ultrasonic Doppler flow meter was used to monitor the cyclic flow reduction （CFR） caused by the repeated formation and shedding of thrombi， and flow cytometry was employed to examine platelet-vWF binding， on the basis of which the effect of PNS on high shear-induced arterial thrombosis was evaluated. ResultThe microfluidic assay showed that PNS decreased the high shear rate （12 000 s^-1） or Yoda1-induced calcium influx， platelet-vWF binding， vWF-mediated platelet-fibrinogen binding， and vWF release from platelet alpha-granules in a dose-dependent manner. In the mouse model of high shear-induced thrombosis， PNS markedly reduced the CFR and occlusion time of the common carotid artery and inhibited platelet-vWF binding. ConclusionPNS can mitigate pathological shear-induced platelet aggregation and arterial thrombosis via influencing Piezo1/GPIbα-vWF signaling.

There are some limitations in the localization of epileptogenic zone commonly used by human eyes to identify abnormal discharges of intracranial electroencephalography in epilepsy. However, at present, the accuracy of the localization of epileptogenic zone by extracting intracranial electroencephalography features needs to be further improved. As a new method using dynamic network model, neural fragility has potential application value in the localization of epileptogenic zone. In this paper, the neural fragility analysis method was used to analyze the stereoelectroencephalography signals of 35 seizures in 20 patients, and then the epileptogenic zone electrodes were classified using the random forest model, and the classification results were compared with the time-frequency characteristics of six different frequency bands extracted by short-time Fourier transform. The results showed that the area under curve (AUC) of epileptic focus electrodes based on time-frequency analysis was 0.870 (delta) to 0.956 (high gamma), and its classification accuracy increased with the increase of frequency band, while the AUC by using neural fragility could reach 0.957. After fusing the neural fragility and the time-frequency characteristics of the γ and high γ band, the AUC could be further increased to 0.969, which was improved on the original basis. This paper verifies the effectiveness of neural fragility in identifying epileptogenic zone, and provides a theoretical reference for its further clinical application.
