OBJECTIVE To evaluate the cost-effectiveness of clopidogrel versus aspirin monotherapy regimens for secondary prevention of ischemic stroke and to provide economic evidence and reference for clinical medication and decision-making. METHODS Based on the CAPRIE trial， a Markov model was constructed； the probabilities of risk events， health utility values， and costs of risk event management were obtained from relevant literature. The cycle length was 6 months， and the time horizon was 10 years. A discount rate of 5% per year was applied. The primary outcomes were total costs， quality-adjusted life-years （QALYs）， and incremental cost-effectiveness ratio （ICER）. Cost-utility analysis was performed for above 2 regimens by using TreeAge Pro software. The one-way sensitivity analysis， probabilistic sensitivity analysis and scenario analysis were conducted to validate the robustness of the analyses. RESULTS Compared with the aspirin regimen （325 mg/d of CAPRIE trial dose）， the ICER values of clopidogrel regimen for secondary stroke prevention for 10 years， 20 years and 30 years were 4 284.06， 4 201.20 and 3 986.78 yuan/QALY， respectively， which were E-mail：liuxiaoyanrj@sjtu.edu.cn all less than the willing-to-pay （WTP） threshold of one time 。 China’s per capita gross domestic product （GDP） in 2021. E-mail：scilwsjtu-wb@yahoo.com Compared with the aspirin regimen （clinically recommended dose in China， 100 mg/d）， the ICER values of clopidogrel regimen for stroke secondary prevention for 10 years， 20 years and 30 years were 58 238.27， 42 164.72 and 36 164.77 yuan/QALY， respectively， which were all less than WTP threshold. When comparing with aspirin regimen of 325 mg/d， results of one-way sensitivity analysis showed that the cost of clopidogrel and aspirin， probability of the first recurrence of ischemic stroke were sensitive factors of model. Results of probabilistic sensitivity analysis showed that when WTP was set at one time GDP per capita in China in 2021， clopidogrel had a probability of being cost- effective of about 66.5%. Results of scenario analysis showed that neither changing the time horizon to 10， 20 or 30 years nor using different doses of aspirin （50， 100， 150， 200 or 250 mg/d） would not alter any conclusions. CONCLUSIONS Compared with aspirin monotherapy， clopidogrel monotherapy is more cost-effective for secondary prevention of ischemic stroke.

Objective To explore the effectiveness of the Five Elements Music Therapy(FEMT)in relieving stress in participants with different cultural backgrounds,and to compare the differences between the FEMT and the Western Art Music Therapy(WAMT)in stress relief.Methods This was a comparative pilot randomized pre-post repeated measures study,37 subjects were allocated with 2 dropped out,with an inclusion-ended sample of 35 subjects,23 from Canada and 12 from China.After informed consent,all subjects were randomly assigned to listening to either Five Elements Music or Western Art Music at home for 30 minutes,twice a week for four weeks.Participants were asked to use headphones,measure their pulse rate before and after each session,and fill out five questionnaires,including a background and demographic survey(reporting age,gender,education,cultural background,listening experience).Self-assessment of stress(pre-post after each session),General Hospital Anxiety/Depression Scale(HADS,weekly after 2nd session),Perceived Stress Survey(PSS,weekly after 2nd session),the Music Therapy Intervention Survey(MTIS,pre-post each session).Results ①There was a significant decrease in self-assessed stress scores after the second session in the FEMT compared with the WAMT group(t=-2.057,P=0.046).②In both groups,there was a significant decrease in stress scores pre-post treatment in each group(WAMT t=5.026;FEMT T=7.645,P=0.000).③There was no significant difference between the two groups in post-intervention HADS scores(P>0.05);In the Chinese sample,there was a significant difference in HADS scores after the eighth session in both FEMT and WAMT groups(t=-3.862,P=0.003),and a statistically significant difference in HADS pre-post intervention in the FEMT((t=5.117,P=0.004).There was a significant difference in MTIS pre-post treatment in the WAMT(t=-2.572,P=0.023),but in not the FEMT group(t= 1.331,P=0.207).Conclusion This pilot trial explores a safe and feasible self-administered music therapy approach for stress in two distinct cultural groups,and for the first time provides preliminary comparison and evidence of effectiveness of FEMT and WAMT in alleviating stress and anxiety.Further investigation with bigger randomized samples is needed to elucidate the effects of different kinds of music and cultural groups on stress and anxiety levels.

OBJECTIVE: To observe the effect of triamcinolone combined with vitamin E on preventing fibrous capsule contracture following the second breast augmentation. METHODS: Totally 65 patients who had 130 breasts receiving the second breast augmentation at the Department of Plastic and Aesthetic Surgery, No.1 People's Hospital of Nanning were collected and served as the treatment group, including 47 cases with capsules contracture and 18 cases with hydrogel clearing. Tri-Kort was injected after the second breasts augmentation, and vitamin E was taken orally for 3 months. Additional 65 cases with 130 breasts received the second breast augmentation were served as control group. The follow-up was performed after half month, and the curative effect was evaluated by Baker grading at 1 year after operation. RESULTS: All cases in the two groups were received 6-24 months follow-up. Only 3 cases (5 breasts) in 65 patients (130 breasts) in the treatment group had capsule contracture (Baker II-III), with 3.8% of capsule contracture, which was obviously less than 18% of capsule contracture in the control group (P < 0.01,13 cases with 23 breasts in the control group). Simultaneously, no drug adverse reaction occurred in the treatment group. CONCLUSION: Triamcinolone combined with vitamin E can obviously depress the rate of capsule contracture after the second breast implantation.
