Objective:To explore the predictive value of preoperative pelvic floor electromyography(EMG)parameters for the risk of urinary incontinence after prostate cancer surgery.Methods:This study retrospectively analyzed the medical records of 271 patients who underwent radical prostatectomy in the urology department of Peking University First Hospital from January 2020 to October 2022.The data included patient age,body mass index(BMI),international prostate symptom score(IPSS),prostate-specific antigen(PSA)levels,Gleason score,type of surgery,urethral reconstruction,lymph node dis-section,nerve preservation,catheterization duration,D'Amico risk classification,American Society of Anesthesiologists(ASA)score,Charlson comorbidity index,postoperative duration,prostate volume,and pelvic floor EMG parameters(pre-resting mean,fast muscle mean,and slow muscle mean scores).Independent risk factors affecting early postoperative urinary incontinence were identified through multiva-riate Logistic regression analysis.The predictive efficacy of pelvic floor EMG results was evaluated by cal-culating the area under the receiver operating characteristic(ROC)curve,and the optimal threshold for early postoperative urinary incontinence was determined based on the Youden index and clinical signifi-cance.Results:The study included 271 prostate cancer patients,with an 81.9％rate of voluntary urinary control post-surgery.The median score for fast pelvic floor muscles was 23.5(18.2,31.6),and for slow muscles,it was 12.5(9.6,17.3).Among the patients,179(66.1％)did not preserve nerves,and 110(40.6％)underwent urethral reconstruction.Advanced age and low fast muscle scores were identified as independent risk factors for urinary incontinence.Patients aged ≤60 had 5.482 times the voluntary urinary control rate compared with those aged ≥70(95％CI:1.532-19.617,P＜0.05).There was a significant correlation between fast muscle scores and urinary incontinence recovery(OR=1.209,95％CI:1.132-1.291,P＜0.05).When the optimal threshold for preoperative fast muscle score was set at 18.5,the ROC sensitivity and specificity were 80.6％and 61.2％,respectively.Con-clusion:Preoperative pelvic floor EMG parameters show good predictive accuracy and clinical applicabili-ty for the risk of urinary incontinence after prostate cancer surgery.These parameters can be used for ear-ly identification of urinary incontinence risk,with age and fast muscle scores being important predictors.

Ecto-nucleotide pyrophosphatases/phosphodiesterases(ENPPs)are involved in the hydrolysis of different purine nu-cleotides in a range of physiological processes.In recent years,it has also been found to be involved in tumor progression,with ENPP1 often overexpressed in local recurrence and tumor metas-tasis,which is associated with poor prognosis and survival in a range of solid tumors.The role of ENPP1 in tumors is mainly fo-cused on tumor proliferation,metastasis,immunity,recurrence,etc.,and it is speculated that ENPP1 can be used as a prognos-tic indicator for a variety of tumors.ENPP1 promotes the immu-nosuppressive tumor microenvironment by being obliquely in-volved in the regulation of ATP/adenosine homeostasis by com-bining with other components,which crosses with interferon gene stimulators to impair its potent immune response through the hy-drolysis of the effector 2',3'-cyclic GMP-AMP.Therefore,EN-PP1 blockade has become an effective means to induce immune remodeling and inhibit tumorigenesis and development.The ex-isting ENPP1 inhibitors mainly include natural small molecule compounds,nucleotide ENPP1 inhibitors,non-nucleotide EN-PP1 inhibitors,and novel small molecule ENPP1 inhibitors.So far,a small number of ENPP1 inhibitors have been developed and are rarely suitable for in vivo experiments,and they are still in the stage of developing effective compounds or lead com-pounds,and the research on ENPP1 inhibitors needs to be fur-ther studied.This review summarizes and discusses the role of ENPP1 in tumors,and summarizes the current research progress of various ENPP1 agents and their current research progress,in order to provide a reference for further research on the prepara-tion of drug candidates.

The mechanisms underlying autophagic defects in nonalcoholic steatohepatitis (NASH) remain largely unknown. We aimed to elucidate the roles of hepatic cyclooxygenase 1 (COX1) in autophagy and the pathogenesis of diet-induced steatohepatitis in mice. Human nonalcoholic fatty liver disease (NAFLD) liver samples were used to examine the protein expression of COX1 and the level of autophagy. Cox1^Δhepa mice and their wildtype littermates were generated and fed with 3 different NASH models. We found that hepatic COX1 expression was increased in patients with NASH and diet-induced NASH mice models accompanied by impaired autophagy. COX1 was required for basal autophagy in hepatocytes and liver specific COX1 deletion exacerbated steatohepatitis by inhibiting autophagy. Mechanistically, COX1 directly interacted with WD repeat domain, phosphoinositide interacting 2 (WIPI2), which was crucial for autophagosome maturation. Adeno-associated virus (AAV)-mediated rescue of WIPI2 reversed the impaired autophagic flux and improved NASH phenotypes in Cox1^Δhepa mice, indicating that COX1 deletion-mediated steatohepatitis was partially dependent on WIPI2-mediated autophagy. In conclusion, we demonstrated a novel role of COX1 in hepatic autophagy that protected against NASH by interacting with WIPI2. Targeting the COX1-WIPI2 axis may be a novel therapeutic strategy for NASH.

Adolescents are in a transition period from children to adults, during which they are prone to a variety of emotional disorders, with anxiety and depression being the most common disorders. Anxiety and depressive symptoms are highly correlated and the comorbidity of anxiety and depression is common. At the same time, the most prominent behavioral changes in adolescence are the emergence of getting up late and sleeping late, and the circadian rhythm begins to delay. Previous studies have shown that circadian rhythm is closely related to anxiety and depression, but the association between circadian rhythm disorder and comorbidity of anxiety and depression remains unclear. This article reviews the prevalence, association and potential biological mechanism of circadian rhythm disorder and comorbidity of anxiety and depression in adolescents, so as to provide a possible reference for the prevention and control of comorbidity of anxiety and depression in adolescents.

Objective: Using Meta-analysis to evaluate the vaccine effectiveness of 13-valent pneumococcal conjugate vaccine (PCV13) against invasive Streptococcus pneumoniae disease (IPD) caused by serotype 19A in children <5 years old. Methods: "Streptococcus pneumoniae infection""invasive pneumococcal disease""13-valent pneumococcal polysaccharide conjugate vaccine""PCV13""effectiveness""infant""child" and related terms were searched from China National Knowledge Infrastructure (CNKI), WANFANG DATA, PubMed, SCOPUS and Web of science with no limited on language, region and research institution. The retrieval time was limited from January 2010 to February 2023 and cohort study, case-control study and randomized controlled trial were included. Data were extracted from eligible studies by two independent reviewers, and after study quality assessment by NOS scale, Meta-analysis was completed using Stata 16.0 software. Results: A total of 2 340 related literatures were searched, and 10 literatures were finally included, including 5 case-control studies and 5 indirect cohort studies, which showed good literature quality. The vaccine effectiveness against serotype 19A IPD of PCV13 in children was 83.91% (95%CI: 78.92%-88.89%), and the subgroup analysis (P=0.240) showed there was no significant difference among the case-control study (VE=87.34%, 95%CI:79.74%-94.94%) and the indirect cohort study (VE=81.30%, 95%CI:74.69%-87.92%). The funnel plot and Egger test suggested that the possibility of publication bias was small. Conclusion: The present evidence indicates that PCV13 has a good vaccine effectiveness against serotype 19A IPD in children, and it is recommended to further increase the vaccination rate of PCV13 to reduce the disease burden of IPD in children <5 years old.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

Objective: To analyze the folate status among women of childbearing age worldwide from 2000 to 2020, and explore the impact of socioeconomic factors on folate status, so as to provide support for the formulation of relevant supplementary policies in China in the future. Methods: The "folate" "folic acid" "deficiency" "status" "women" "childbearing" and "reproductive" were used as Chinese and English keywords to systematically search CNKI and PubMed database. Global Health Data Exchange database (GDHx), Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia datasets (BRINDA) and Ground Work publications were systematically searched with "micronutrients" and "nutrition" as keywords. The retrieval time was from January 1, 2000 to August 31, 2020, and the language was restricted to English and Chinese. After title, abstract and full-text screening, a total of 45 literatures were included. The folate status of women of childbearing age in the eligible literature was analyzed, and the income and folate status were tested by Kruskal Wallis H test and Nemenyi test. Results: The M (Q₁, Q₃) of serum folate deficiency rate and erythrocyte folate insufficiency rate in women of childbearing age were 15.0% (3.5%, 37.0%) and 49.0% (22.0%, 83.0%). There were great differences in serum folate status and serum folate deficiency rate among women of childbearing age in different income countries. The serum folate deficiency rate of women of childbearing age in low-income countries was significantly higher than that in middle and high-income countries. Conclusion: The folate status of women of childbearing age in most countries has not reached the ideal state from 2000 to 2020. More studies on folate supplementation programs should be carried out.

OBJECTIVE: To explore the mechanisms underlying the proliferative inhibition of Chinese herbal medicine Kang-Ai injection (KAI) in gastric cancer cells. METHODS: Gastric cancer cell lines MGC803 and BGC823 were treated by 0, 0.3%, 1%, 3% and 10% KAI for 24, 48 and 72 h, respectively. The cell proliferation was evaluated by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. The apoptosis and cell cycle were evaluated by flow cytometry. Interleukin (IL)-6 mRNA and protein expression levels were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-linked immune sorbent assay (ELISA), respectively. The protein expression levels of cyclin A, cyclin E, cyclin B1, cyclin D1, p21, retinoblastoma (RB), protein kinase B (AKT), extracellular regulated protein kinases (ERK), signal transducer and activator of transcription (STAT) 1 and STAT3 were detected by Western blot. RESULTS: KAI inhibited the proliferation of MGC803 and BGC823 gastric cancer cells in dose- and time-dependent manner. After treated with KAI for 48 h, the proportion of G1 phase was increased, expression level of cyclin D1 and phosphorylation-RB were down-regulated, whereas the expression of p21 was up-regulated (all P<0.01). Furthermore, 48-h treatment with KAI decreased the phosphorylation level of STAT3, inhibited the mRNA and protein expressions of IL-6 (all P<0.01). IL-6 at dose of 10 ng/mL significantly attenuated the proliferative effect of both 3% and 10% KAI, and recovered KAI-inhibited STAT3 phosphorylation and cyclin D1 expression level (all P<0.01). CONCLUSION KAI exerted an anti-proliferative function by inhibiting IL-6/STAT3 signaling pathway followed by the induction of G₁ phase arrest in gastric cancer cells.
