Objective As primary Sj?gren's syndrome(pSS)primarily affects the salivary glands,saliva can serve as an indicator of the glands'pathophysiology and the disease's status.This study aims to illustrate the salivary proteomic profiles of pSS patients and identify potential candidate biomarkers for diagnosis. Methods The discovery set contained 49 samples(24 from pSS and 25 from age-and gender-matched healthy controls[HCs])and the validation set included 25 samples(12 from pSS and 13 from HCs).Totally 36 pSS patients and 38 HCs were centrally randomized into the discovery set or to the validation set at a 2:1 ratio.Unstimulated whole saliva samples from pSS patients and HCs were analyzed using a data-independent acquisition(DIA)strategy on a 2D LC-HRMS/MS platform to reveal differential proteins.The crucial proteins were verified using DIA analysis and annotated using gene ontology(GO)and International Pharmaceutical Abstracts(IPA)analysis.A prediction model for SS was established using random forests. Results A total of 1,963 proteins were discovered,and 136 proteins exhibited differential representation in pSS patients.The bioinformatic research indicated that these proteins were primarily linked to immunological functions,metabolism,and inflammation.A panel of 19 protein biomarkers was identified by ranking order based on P-value and random forest algorichm,and was validated as the predictive biomarkers exhibiting good performance with area under the curve(AUC)of 0.817 for discovery set and 0.882 for validation set. Conclusions The candidate protein panel discovered may aid in pSS diagnosis.Salivary proteomic analysis is a promising non-invasive method for prognostic evaluation and early and precise treatments for pSS patients.DIA offers the best time efficiency and data dependability and may be a suitable option for future research on the salivary proteome.

OBJECTIVE: To compare the clinical therapeutic effect between electroacupuncture at "four points of sacral region" and transurethral Erbium laser in treatment of moderate to severe stress urinary incontinence after radical prostatectomy. METHODS: A total of 68 patients of moderate to severe stress urinary incontinence after radical prostatectomy were divided into an electroacupuncture group (34 cases) and an Erbium laser group (34 cases, 3 cases dropped off) according to the settings. In the electroacupuncture group, electroacupuncture was applied at "four points of sacral region", i.e. points of 0.5 cun beside bilateral sacrococcygeal joints and bilateral Huiyang (BL 35), with continuous wave, 2 Hz in frequency, 60 min each time, once every other day, 3 times a week, 12 times as one course of treatment. In the Erbium laser group, transurethral Erbium laser technology was given, once every 4 weeks as one course of treatment. Both groups were treated for 5 courses. The scores of the International Consultation on Incontinence questionnaire-short form (ICI-Q-SF) and the incontinence quality of life questionnaire (I-QOL) were observed before treatment, after each course of treatment and in follow-up after 1 and 2 months of treatment completion, respectively, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: Compared with those before treatment, the ICI-Q-SF scores were decreased while the I-QOL scores were increased after 5 courses of treatment and in follow-up after 1, 2 months of treatment completion in the two groups (P<0.01). The ICI-Q-SF score in follow-up after 2 months of treatment completion were higher than that after 5 courses of treatment in the Erbium laser group (P<0.05). After 3, 4, 5 courses of treatment and in follow-up after 1 and 2 months of treatment completion, the ICI-Q-SF scores in the electroacupuncture group were lower than those in the Erbium laser group (P<0.05, P<0.01); after 2, 3, 4, 5 courses of treatment and in follow-up after 1 and 2 months of treatment completion, the I-QOL scores in the electroacupuncture group were higher than those in the Erbium laser group (P<0.01). The change ranges of ICI-Q-SF score and I-QOL score between before treatment and after each course of treatment in the electroacupuncture group were lager than those in the Erbium laser group (P<0.01, P<0.05). The total effective rate was 61.8% (21/34) in the electroacupuncture group, which was superior to 19.4 (6/31) in the Erbium laser group (P<0.01). CONCLUSION Both electroacupuncture at "four points of sacral region" and transurethral Erbium laser can improve the clinical symptoms and the quality of life in patients of moderate to severe stress urinary incontinence after radical prostatectomy. The short-term efficacy and long-term efficacy of electroacupuncture are superior to the Erbium laser technology.

Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.

From January 2019 to December 2021, overweight and obese children who visited in health outpatient Center of Hunan Children's Hospital were studied to explore and analyze the rate, related factors and patterns of multimorbidity of overweight and obesity-related diseases in children in Hunan Province. Univariate and multivariate logistic regression models were used to analyze the multimorbidity-related factors of overweight and obesity-related diseases in children. Association rules (apriori algorithm) were used to explore the multimorbidity patterns of overweight and obesity-related diseases in children. A total of 725 overweight and obese children were included in this study. The multimorbidity rate of overweight and obesity-related diseases in children was 46.07% (334/725). Age, waist circumference, the frequency of food consumption such as hamburgers and fries and adding meals before bedtime were multimorbidity-related factors of overweight and obesity-related diseases in children. The multimorbidity associated with nonalcoholic fatty liver disease (NAFLD) was relatively common. The patterns with the top three support degrees were "NAFLD+dyslipidemia","NAFLD+hypertension" and "NAFLD+hyperuricemia". The patterns with the top three confidence and elevation degrees were "Hypertension+dyslipidemia => NAFLD","Hyperuricemia => NAFLD" and "NAFLD+hypertension => dyslipidemia".

OBJECTIVES: To investigate the prevalence rate of non-alcoholic fatty liver disease (NAFLD) in overweight/obese children who visit a hospital, and to explore the influencing factors of NAFLD, in order to provide a basis for the prevention of NAFLD in overweight/obese children. METHODS: Overweight/obese children who visited Hunan Children's Hospital from June 2019 to September 2021 were recruited. The prevalence rate of NAFLD was examined. Logistic regression analysis was used to explore the factors influencing the development of NAFLD [non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH)]. Receiver operating characteristic curve analysis was used to evaluate the predictive value of the influencing factors for NAFL and NASH. RESULTS: A total of 844 overweight/obese children aged 6-17 years were enrolled. The prevalence rate of NAFLD in overweight/obese children was 38.2% (322/844), among which the prevalence rates of NAFL and NASH were 28.8% (243/844) and 9.4% (79/844), respectively. Multivariate logistic regression analysis showed that the increase of waist-to-hip ratio (WHR) and low high-density lipoprotein cholesterol (HDL-C) were associated with the development of NAFL and NASH (P<0.05). The receiver operating characteristic curve analysis showed that the combined measurement of WHR and HDL-C had a predictive value for NAFL (area under the curve: 0.653, 95%CI: 0.613-0.694), and for NASH (area under the curve: 0.771, 95%CI: 0.723-0.819). CONCLUSIONS The prevalence rate of NAFLD in overweight/obese children who visit a hospital is high. WHR and HDL-C are associated with the development of NAFLD and the combined measurement of WHR and HDL-C has a certain value for predicating the development of NAFLD.

Mitosis is important for cell proliferation in eukaryotes, and chromosome replication and accurate separation are essential for cell division. Supervillin is a membrane and microfilament actin binding protein. Previous studies have found that it regulates the dynamic changes of the cortical distribution of F-actin and myosin II in cytokinesis, thus ensuring the correct distribution of the contraction ring and participating in the final completion of cytoplasm divisions. But it is not clear whether it functions during metaphase. Supervillin has several splicing isomers, among which supervillin isoform 4 (SV4) is the largest splicing isomer. In this study, the expression of SV4 in cells was reduced by the RNA interference method, and the dynamic process of mitosis and the morphology of astral spindles were detected and observed by real-time microscopy and immunofluorescence staining, and the potential molecular mechanism of SV4 in mitosis was analyzed. The results showed abnormal cell divisions after SV4 reduction: delayed transition from metaphase to anaphase (P<0.001), abnormal assembly of microtubules, a twofold-increase of the number of cells with multipolar spindles, and decreased γ-tubulin signaling in the centrosome (P<0.001). Through GST pull-down and mass spectrometry experiments, we found that SV4 and Aurora A bind to each other, and SV4 regulates the localization and activation of Aurora A in the centrosome during mitosis. In summary, supervillin plays an important role in mitosis. The isomer SV4 regulates spindle integrity and γ-tubulin recruitment by interacting with Aurora A and recruiting it for proper localization and activation in the centrosome during the metaphase, thus promoting the correct assembly of bipolar spindles and ensuring the accurate separation of chromosomes and the smooth progress of mitosis.

Objective: To investigate the prevalence of suicidal ideation among MSM, and to explore the influence of perceived social support and depression on suicidal ideation and the possible pathway. Methods: MSM who are ≥18 years, HIV-negative, and ever had sex with men (oral sex/anal sex) in the last year participated in is study. Cross-sectional survey and convenient sampling method were used to recruit MSM through a male social interaction platform Blued 7.5 software from December 2020 to March 2021, with a questionnaire survey. Demographic questionnaire, Perceived Social Support Questionnaire and Center for Epidemiologic Studies Depression Scale were employed to collect data. Mplus 8.3 was used for data analysis. Results: Among 1 394 eligible MSM participants, 25.7% (358/1 394) had suicidal ideation. Perceived social support could have a direct effect on suicidal ideation (β=-0.11, P=0.009), and an indirect effect on suicidal ideation through depression (β=-0.18, P<0.001). Conclusions: Suicidal ideation was found to be lower in MSM with a higher level of perceived social support and a lower level of depression. Using social media to improve MSM's perceived social support and reduce depressive symptoms might be an effective means to prevent suicidal ideation.
