Objective To explore the visiting behavior and health management strategy of patients with cardiovascular disease (CVD) and the industry management strategies under the family doctor contract service model. Methods A total of 351 patients with CVD from January 2022 to January 2025 were included in the case investigation by random sampling. Taking the number of visits in community health service institutions/total number of visits ≥90% as high compliance, the influencing factors of the visiting behavior of CVD patients were analyzed. Results Finally, 344 valid questionnaires were collected, with an effective recovery rate of 98.01%. The study subjects were categorized into high compliance group (271 cases) and low compliance group (73 cases). The scores of policy cognition understanding, institutional trust and medical service understanding in the high compliance group were higher compared with those in the low compliance group (P<0.05). There was no significant difference in the understanding of medical expenses between the two groups (P>0.05). Multivariate logistic regression model analysis revealed that CVD duration [OR (95% CI): 1.72 (1.21-2.44)], policy cognition understanding [OR (95% CI): 2.16 (1.20-3.89)] and institutional trust [OR (95% CI): 1.88 (1.08-3.25)] were independently associated with medical treatment behavior in CVD patients (P<0.05). Conclusion Enhancing the policy cognition understanding and institutional trust of CVD patients on family doctor contract service can promote patients to seek medical treatment and promote the high-quality development of family doctor contract service.

OBJECTIVE:To optimize the extraction technology of Bushen huoxue capsules. METHODS:Central composite de-sign-response surface method was used to optimize the extraction technology with the amount of water and boiling time as main fac-tors using normalized value of the contents of icariin and salvianolic acid B,the yield of dry extract as index. Validation test was al-so conducted. RESULTS:The optimal extraction technology was as follows as 15-fold water,reflux extracting for 75 min,extract-ing for 2 times. The deviation of measured value and predicted value was 0.000 3% in validation test. CONCLUSIONS:The cen-tral composite design-response surface method can be used to optimize the extraction technology of Bushen huoxue capsules with good prediction,and the technology is simple and stable.
