Objective To optimize the extraction of volatile oil from Qingjie Granules and process of inclusion compound of beta-cyclodextrin. Methods Water Distillation was used for extraction. Extraction time, grinding degree, and the amount of water were set as inspection factors, and volatile oil volume was set as the evaluation index to inspect extraction process of volatile oil from Qingjie Granules. With inclusion rate as the evaluation index, the single factor test and the Box-Behnken combined with the response surface method were used to choose the optimum inclusion process. Results The optimum extraction process for Schizonepetae Herba, Saposhnikoviae Radix and Forsythiae Fructus coarse powder should be with 10 times amount of water, extracting 3 h. Inclusion method should be saturated water solution method, and the inclusion process of volatile oil as feed and beta-cyclodextrin inclusion ratio was 1:12; the temperature was 40 ℃; inclusion time was 3.5 h. By means of TLC, UV and IR spectra, the formation of the inclusion compound of volatile oil in clear solution particles was preliminarily proved. Conclusion The optimum extraction and inclusion process of volatile oil from Qingjie Granules are stable and feasible, which can be used in industrial production.

OBJECTIVE:To est ablish the working mode of the first pharmaceutical ward rounds of clinical pharmacists in our hospital,in order to provide a useful reference for establishing a national standardized pharmaceutical ward rounds model. METHODS:By sharing the clinical cases of the first pharmaceutical ward rounds ,the work content and process of the first pharmaceutical ward rounds in our hospital were introduced. RESULTS & CONCLUSIONS :The clinical pharmacist ’s first pharmaceutical ward round in our hospital mainly includes self introduction of clinical pharmacists ,diagnosis of patients ’condition under the guidance of doctors ,collection and evaluation of patients ’previous medication information (including previous medication varieties ,usage methods ,efficacy and safety evaluation ),assistance for doctors in formulating initial treatment plan , carrying out initial medication and diet education ,and intensive communication and cooperation with nurses. The development of first pharmaceutical ward rounds promotes the rational use of drugs in clinic ,elevates the hospitalization satisfaction of patients and improves the professional quality of clinical pharmacists.

[Objective] To investigate the factors associated with alanine aminotransferase (ALT) abnormalities in multi-ethnic blood donors across five Zang autonomous prefectures in the plateau regions of Qinghai Province, and to provide evidence for ensuring blood safety and formulating screening strategies. [Methods] A retrospective analysis was performed on the ALT abnormal test results of blood donors in the Zang autonomous prefectures of Qinghai from 2022 to 2024. The correlations between ALT levels and factors including gender, age, altitude, and infectious markers were investigated. [Results] The overall ALT unqualified rate among blood donors in this region was 9.01%. Significant differences in ALT levels were observed across genders and age groups (P<0.05). Variations in ALT abnormality rates were also noted among different plateau regions (P<0.05). Overall, ALT values exhibited an increasing trend with rising altitude. The average ALT unqualified rates were 11.19% in Zang donors, 7.96% in Han donors, and 4.79% in donors from other ethnic groups (P<0.05). No statistically significant association was observed between ALT abnormality and the presence of HBV/HCV infectious markers (P>0.05). [Conclusion] In the plateau areas of Qinghai, multi-ethnic blood donors have a relatively high ALT levels and ALT unqualified rates, showing distinct regional characteristics. ALT elevation in voluntary blood donors is related to non-pathological factors such as gender, age, and dietary habits, but not to infectious indicators.
