Objective:To explore the impact and cost-effectiveness of community stroke screening intervention mode on stroke risk.Methods:A total of 3 561 community people over 40 years old who participated in screening intervention in 2017,2019 and 2021 were selected as research objects,and stroke risk was divided into low risk,medium risk and high risk.A Markov model was established to explore the impact of screening intervention mode on stroke risk in community population.The cost increment during the phase I trial was calculated,and the life year increment was adjusted according to the quality estimate of previous studies.The cost-effectiveness increment ratio was calculated,and the screening intervention mode was evaluated,and univariate sensitivity analysis was performed.Results:Within a certain range,intervention screening could effectively shift the status of residents to the low-risk direction,and finally stabilize the distribution of low-risk,medium-risk and high-risk were 47.4％,31.0％and 21.6％.The incremental cost of interventional screening was 160 245 yuan,the incremental quality-adjusted life year was 151.129 yuan,and the incremental cost-effectiveness ratio(ICER)was 1 060.319 yuan/QALY,which was less than 1 times the per capita GDP.The intervention program was fully cost-effective.Conclusion:Screening intervention can promote the transformation of the commu-nity population to a low-risk state of stroke in the prevention stage,and this approach has good cost-effectiveness performance.It is recommended that the primary medical and health institutions that are not enough to fully implement the integrated process ser-vice of community prevention and treatment of stroke should first implement low-cost screening intervention.

Objective To evaluate the efficacy and safety of brexpiprazole in treating acute schizophrenia.Methods Patients with schizophrenia were randomly divided into treatment group and control group.The treatment group was given brexpiprozole 2-4 mg·d-1 orally and the control group was given aripiprazole 10-20 mg·d-1orally,both were treated for 6 weeks.Clinical efficacy of the two groups,the response rate at endpoint,the changes from baseline to endpoint of Positive and Negative Syndrome Scale(PANSS),Clinical Global Impression-Improvement(CGI-S),Personal and Social Performance scale(PSP),PANSS Positive syndrome subscale,PANSS negative syndrome subscale were compared.The incidence of treatment-related adverse events in two groups were compared.Results There were 184 patients in treatment group and 186 patients in control group.After treatment,the response rates of treatment group and control group were 79.50％(140 cases/184 cases)and 82.40％(150 cases/186 cases),the scores of CGI-I of treatment group and control group were(2.00±1.20)and(1.90±1.01),with no significant difference(all P＞0.05).From baseline to Week 6,the mean change of PANSS total score wese(-30.70±16.96)points in treatment group and(-32.20±17.00)points in control group,with no significant difference(P＞0.05).The changes of CGI-S scores in treatment group and control group were(-2.00±1.27)and(-1.90±1.22)points,PSP scores were(18.80±14.77)and(19.20±14.55)points,PANSS positive syndrome scores were(-10.30±5.93)and(-10.80±5.81)points,PANSS negative syndrome scores were(-6.80±5.98)and(-7.30±5.15)points,with no significant difference(P＞0.05).There was no significant difference in the incidence of treatment-related adverse events between the two group(69.00％vs.64.50％,P＞0.05).Conclusion The non-inferiority of Brexpiprazole to aripiprazole was established,with comparable efficacy and acceptability.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.
