Objective To analyze and evaluate the use of small incision in the treatment of senile intertrochanteric fracture in artificial femur head replacement.Method 79～98 years old senile patients suffered from intertrochanteric fracture use small incision and artificial femur head replacement,a total of 18 cases including male 6 cases and female 12 cases,averaged eighty six years old,type of fracture according to Evans classification,type Ⅲ six cases,type Ⅳ eight cases,type Ⅴ four cases.Result 18 cases were followed up for 3～19 months,no case died,joint function in good situation,6～21 days post operation walk with help of tools,the average time was 7 days,use activity rate of hip joint,degree of pain and living self-service situation as criteria,success rate reached 91%,no relaxation or descendent of prosthesis.Conclusion Trauma is relatively small in use small incision and artificial femur head replacement in the treatment of senile intertrochanteric fracture,the result is satisfactory.

OBJECTIVE To develop a mobile intelligent pharmacy management assistant system （abbreviated as “assistant system”）， thus providing convenient support for the daily operational management of pharmacies. METHODS The system was developed using the WeChat developer tools with WXML， WXSS， and JavaScript based on the platform as a service （PaaS）. Test users were recruited， and in five different scenarios， namely pharmaceutical knowledge inquiry， drug damage registration， medication error data analysis， drug expiration date registration， and duty handover， the task execution time was recorded for both the new （assistant system） and old （paper-based records and fixed computer records） modes. Additionally， users’ opinions on the advantages of the new mode were collected. RESULTS The assistant system comprised six modules: shift handover， pharmaceutical knowledge database， medication error registration， drug expiry management， drug damage registration， and medication consultation records. Among 10 test users， in all scenarios except for the shift handover record， the task execution time under the new mode was shorter than that under the old mode （P＜0.05）. Most test pharmacists highlighted that the primary advantages of the new mode lie in its iterative flexibility， and ease of use among other benefits. CONCLUSIONS The assistant system based on PaaS cloud model WeChat mini program developed in this study can significantly improve the daily management efficiency of the pharmacy and optimize the task execution experience for pharmacists.
