Objective:to investigate the expression of integrin αvβ3 and osteopontin(OPN)in decidual tissues in missed abortion women with polycystic ovarian syndrome(PCOS).Methods:PCOS women with missed abor-tion(PCOS missed abortion group),non-PCOS with missed abortion(non-PCOS missed abortion group)and women with normal early pregnancy induced abortion(normal control group)who were admitted to the First Affili-ated Hospital of Xi'an Jiaotong University from February 2018 to December 2022 were selected as participants,and 20 subjects in each group.The expressions of integrin αvβ3 and OPN in decidual tissues among the three groups were detected.Correlation analysis was conducted between the expression levels of integrin αvβ3 and OPN in PCOS patients with missed abortion.Results:Integrin αvβ3 and OPN were mainly expressed in the epi-thelial cells of the uterus,as well as in decidual cells.There were significant differences in the positive rates and IHC scores of integrin αvβ3 and OPN in decidual tissues among the three groups(P<0.05).The positive rates and IHC scores in PCOS missed abortion group were significantly lower compared with non-PCOS missed abor-tion group and normal control group,and the difference was statistically significant(P<0.05),but there was no significant difference between non-PCOS missed abortion group and normal control group(P>0.05).The integrin αvβ3 and OPN in decidual tissues were mainly co-located in uterine epithelial cells.There were significant differ-ences in immunofluorescence intensity of integrin αvβ3 and OPN among the three groups(P<0.05).The missed abortion group of PCOS was significantly lower than that of non-PCOS missed abortion group and normal control group,and the difference was statistically significant(P<0.01).No significant difference was found between non-PCOS missed abortion group and normal control group(P>0.05).There were significant differences in the protein expression levels and mRNA expression levels of integrin αvβ3 and OPN in decidual tissue among the three groups(P<0.05).PCOS missed abortion group was significantly lower than non-PCOS missed abortion group and normal control group,and the difference was statistically significant(P<0.01).There was no significant difference between non-PCOS missed abortion group and normal control group(P>0.05).The results of Pearson correlation analysis showed that the protein and mRNA expression levels of integrin αvβ3 and OPN in decidual tis-sue of PCOS patients with missed abortion were significantly positively correlated(r>0,P<0.01).Conclusions:The integrin αvβ3 and OPN were expressed in both epithelial cells of the uterus and decidual cells in early preg-nancy.The expressions of them were significantly decreased in decidual tissues of PCOS patients with missed a-bortion,which might be related to reduced endometrial receptivity.The role of integrin αvβ3 and OPN in the occur-rence of missed abortion needs further study.

Objective:To compare and explore the diagnostic performance of adding value of transabdominal and transvaginal contrast-enhanced ultrasound (CEUS) to Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of adnexal masses.Methods:A total of 180 adnexal masses with solid components in 175 women were enrolled retrospectively between September 2021 and November 2022. All patients underwent routine Doppler ultrasound examinations and CEUS examinations. Among these masses, 107 masses underwent with transabdominal CEUS, 58 masses underwent with transvaginal CEUS, and 15 masses underwent both transvaginal and transabdominal CEUS. All patients were scheduled for surgery and pathological results served as the reference standard. Routine Doppler ultrasound and CEUS images and video were reviewed by a subspecialty radiologist using Vuebox software. The O-RADS US was downgraded or upgraded according to the CEUS characteristics of the masses. The diagnostic accuracy was assessed using ROC curve analysis. The area under the ROC curve (AUC) was calculated to compare the diagnostic performance of adding value of transabdominal and transvaginal CEUS to O-RADS US.Results:The diagnostic performance of adding transabdominal and transvaginal CEUS to O-RADS US were both significantly higher than of O-RADS US alone (transabdominal CEUS: AUC 0.83 vs 0.76, P=0.018; transvaginal CEUS: AUC 0.92 vs 0.81, P=0.013). Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in the differential diagnosis of adnexal masses ( P=0.047). When the maximal diameter of adnexal masses ≤40 mm, transabdominal combined with O-RADS US presented the lowest diagnostic performance, with an AUC of 0.73. Conclusions:Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in assessing adnexal masses with solid components. When the maximal diameter of adnexal masses ≤40 mm, transvaginal CEUS examination was recommended.

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.

The paper reported a patient under maintained hemodialysis for 11 years, with a large mass appeared in the right thigh after local injury. The mass was clinically considered as tumoral calcinosis combined with clinical, imaging and pathological findings. Several treatments such as enhancing dialysis adequacy, low calcium dialysate, calcimimetic agent, non-calcium- phosphorus binding agents, parathyroidectomy and intravenous infusion of sodium thiosulfate could not vanish the mass. Finally, the lump was surgically removed. The treatment of tumoral calcinosis in the hemodialysis patient can provide a instruction for similar situations in clinical practice.

OBJECTIVE: To assess the value of mapping allele with resolved carrier status (MaReCs) technology for the determination of balanced translocation carrier status for embryos. METHODS: Blastocysts produced by 25 reciprocal translocation carriers and 15 Robertsonian translocation carriers were detected by MaReCs. After genetic counseling, transplantable blastocysts were selected. Amniocentesis was performed to check fetal chromosomes at 16 to 20 gestational weeks, and the consistency of amniocentesis and MaReCs was determined. RESULTS: No significant difference was found in the normal rate for chromosome copy number variations (CNVs) in blastocysts between reciprocal translocation carriers and Robertsonian translocation carriers (28.6% vs. 32.0%, P> 0.05). For 12 (48%) reciprocal translocation carriers and 8 (32%) Robertsonian translocation carriers, the status of translocation carrier of embryos was successfully determined. The results of amniocentesis were consistent with that of MaReCs in all 11 pregnancies. CONCLUSION MaReCs is a reliable method to distinguish the translocation carrier status of embryos of balanced translocation carriers. It can help a certain proportion of balanced translocation carriers to select completely normal embryos while reduce transfer of embryo carrying a balanced translocation.

Objective: To investigate the feasibility and accuracy of transperineal real-time three-dimensional ultrasound combined with clinical factors in predicting the risk of female stress urinary incontinence(SUI). Methods: Three hundred and forty-eight female patients with SUI diagnosed were selected as the case group, and 102 healthy people in the same period were selected as the control group. All subjects underwent transperineal real-time three-dimensional ultrasound. The ultrasonic parameters of resting state, contraction and Valsalva were measured, and the clinical parameters such as age, height, weight, history of pregnancy and childbirth were collected. According to the time sequence, all the subjcets were divided into derivation cohort and verification cohort inproportion to 2∶1, single factor screening and logistic multiple regression analysis were carried out on 24 factors, and the risk model was established. The cut-off value of the disease probability P was determined by the ROC curve of the subjects, and then the accuracy of the cut-off value in predicting SUI was verified in the verification group. Results: Single factor analysis showed that 13 parameters were associated with SUI(all P<0.05). Logit P=2.014+ 1.870×Z₁ was established by multivariate logistic regression analysis. The cut-off value of the disease probability P determined by ROC curve was 0.823. The predictive sensitivity of the model was 68.1% (95%CI: 59.6%-76.6%), specificity was 91.2% (95%CI: 86.0%-96.4%), positive predictive value was 64.3% (95%CI: 55.6%-73.0%) and negative predictive value was 92.5% (95%CI: 86.2%-98.8%). Conclusions It is feasible to predict the risk of female stress urinary incontinence by transperineal real-time three-dimensional ultrasound combined with clinical factors. Although, some limitations with the prediction model, it has accuracy in predicting SUI with obvious symptoms.
