Schizophrenia,a severe mental illness characterized by high disability and chronicity,imposes a heavy disease burden on society and patients in China.Community-based management plays a crucial role in the long-term and comprehensive management of patients with schizophrenia.Through years of exploration,community-based management models—primarily focused on case management,assertive community treatment(ACT),and crisis intervention—have proven beneficial to the overall recovery of patients.However,notable differences exist in the implementation of these models between domestic and international practices.Given this context,we systematically analyze domestic and international research to examine the characteristics of different management models and the causes of the differences.Based on this analysis,we propose targeted recommendations for improving community-based management of schizophrenia in China.Regarding case management,a tiered approach should be adopted according to regional economic conditions and resource availability to optimize the efficiency of resource allocation.For ACT,we suggest developing a family-centered integrated intervention framework adapted to China's specific context.Finally,regarding crisis intervention,a collaborative family-community-police response mechanism should be established,complemented by enhanced professional training and streamlined referral procedures.We advocate enhancing resource allocation and theoretical research,along with broader involvement of all sectors of society,to jointly optimize the community-based management model for schizophrenia in China.

Icariin,which belongs to the class of flavonoids,is the main active ingredient of the traditional tonic Chinese herb Epimedii Folium.Modern studies have shown that icariin has a wide range of effects on the male reproductive system.It has various pharmacological activities such as regulating cell proliferation and apoptosis,antioxidants,promoting testosterone secretion,improving erectile function,inhibiting prostate cancer cell migration,invasion,and regulating cell cycle.It has research value and application prospects in the field of urology and assisted reproduction.Therefore,Icariin's pharmacological effects and molecular mechanisms on the male reproductive system are reviewed in this paper combined with literature visualization analysis.It is expected to provide a theoretical basis for the therapeutic value development and application of icariin in male reproductive health.

Objective To analyze the predictive value of combination of endoscopic ultrasound (EUS)and 64-slice dual-source computed tomography(DSCT)in regional clinical staging and peritoneal metastases of gastric cancer.Methods From July 2011 to May 2017,365 patients with gastric cancer diagnosed by endoscopic biopsy were enrolled.The patients received EUS and DSCT examination with the gold standard of postoperative pathological diagnosis,the accuracies of EUS alone,DSCT alone and the combination of EUS and DSCT were evaluated in original gastric tumor,regional lymph nodes and peritoneal metastases.The accuracy,sensitivity,specificity,the positive predictive value,the negative predictive value,consistency(the value of K ap pa)and area under curve(AUC)of receiver operating characteristic(ROC)curve were calculated.Results A total of 263 patients were enrolled into the study on the depth of tumor invasion and clinical staging of regional lymph nodes and 289 patients were recruited into the clinical prediction study on peritoneal metastasis.The accuracy of EUS in clinical staging of the depth of tumor invasion was 75.29% and the sensitivity,specificity,the value of Kappaand AUC of EUS in clinical staging of regional lymph nodes were 86.26%,81.81%,0.681 and 0.840,respectively.The sensitivity,specificity,the value of Kappaand AUC of DSCT in clinical staging of regional lymph nodes were 74.81%,87.12%,0.620 and 0.813,respectively.The sensitivity,specificity,the value of Kappa and AUC of EUS in the prediction of peritoneal metastases were 38.24%,97.25%,0.432 and 0.668, respectively.The sensitivity,specificity,the value of Kappa and AUC of DSCT in the prediction of peritoneal metastases were 41.18%,100.00%,0.553 and 0.706,respectively.The accuracy and the value of Kappaof the combination of EUS and DSCT in clinical staging of the depth of tumor invasion were 75.29% and 0.639;the sensitivity,specificity,positive predictive value,negative predictive value, Kappa,AUC in clinical staging of regional lymph nodes were 93.13%,87.88%,88.41%,92.80%, 0.810 and 0.905,respectively;and the sensitivity,specificity,positive predictive value,negative predictive value,Kappa,AUC in the prediction of peritoneal metastases were 58.82%,97.25%, 74.07%,94.66%,0.616 and 0.774,respectively.Conclusions The combination of EUS and DSCT which is superior to single examination is very helpful in the depth of gastric cancer invasion and regional lymph nodes,and is helpful in the prediction of peritoneal metastasis. The combination of two complementary examinations can improve the accuracy of the depth of gastric cancer invasion,clinical staging of regional lymph nodes,and the prediction of peritoneal metastasis.
