OBJECTIVE:To study the purification technology of Sanhuang yishen formula. METHODS:Using retention rate and impurity rate of purified total polysaccharide,astragaloside and calycosin glucoside as index,the purification effects of water extraction and alcohol precipitation method (50%,60%,70% ethanol) and clarifying agent method (101 juice clarifying agent, ZTC natural clarifying agent,chitosan clarifying agent) were respectively detected to screen the purification method;orthogonal test was used to optimize the technology parameters(mass concentration of liquid,amount of clarifying agent and pH of liquid)by the optimized purification method,and the verification test was conducted. RESULTS:The purification was better when using chito-san as clarifying agent with comprehensive score of 98.62;the purified technology parameters were mass concentration of liquid 1 g/mL,1% chitosan solution amount of 2 mL/g,pH 5.1;the average value of retention rate and impurity rate of purified total poly-saccharide, astragaloside and calycosin glucoside in verification test were 79.56%(RSD=1.24%, n=3), 78.11%(RSD=0.97%,n=3),79.46%(RSD=1.03%,n=3)and 32.18%(RSD=1.16%,n=3),respectively. CONCLUSIONS:Using chito-san as clarifying agent shows good purification effect for Sanhuang yishen formula,which is simple. The optimized technology is stable and feasible.

Objective To conduct a systematic review of relevant literature to understand the current status and influencing factors of telehealth readiness of clinical medical staff.Methods The Chinese and English databases of CNKI,Wanfang database,VIP,SinoMed,Pubmed,Embase,Cochrane Library,CINAHL,Web of Science were searched by computer.The Chinese and English literatures on the current status and influencing factors of remote health care readiness among medical staff personnel were collected.The search time was from the establishment of the database to July 12th,2023,and the literature was screened and evaluated.After data extraction and integration of the literature,descriptive analysis is conducted.Results 18 articles were ultimately included,involving 12 298 medical staff members.Research shows that the readiness of clinical medical staff for telehealth is currently at a moderate level and not optimistic.The relevant influencing factors are:medical staff factors,including general demography factors,willingness of medical care services,innovative self-efficacy,understanding and participation of telehealth care mode,and electronic information ability;organizational factors:including telemedicare policies,telemedicare training,sufficient human resource working environment and atmosphere,hospital level and type.Conclusions The readiness of clinical medical staff for remote health care is at a moderate level,but their willingness to participate in remote health care is high.It is recommended to construct a scientific and feasible remote health care training program for medical staff in the future to improve the quality of hospital services.

OBJECTIVE:To establish an overall quality evaluation model for Agrimonia pilosa based on extract and characteristic spectrum,and to provide evidence for comprehensive quality evaluation of the medicinal material and screening of high-quality provenance. METHODS :Referring to different extraction method and solvent condition stated in 2015 edition of Chinese Pharmacopoeia (part Ⅳ),using the content and total peak area of HPLC characteristic chromatogram of extract as indexes,and the extraction technology was optimized by weighted comprehensive score. HPLC characteristic spectrum of 15 batches of A. pilosa was established ,and similarity evaluation and characteristic peak identification were performed. SPSS 25.0 software was used to conduct single factor analysis and Pearson correlation analysis for the extract content and total peak area of A. pilosa from different origins. The quality of medicinal materials from different origins were compared. Entropy weight TOPSIS method was adopted to evaluate comprehensive quality of A. pilosa using the extract content and total peak area of 15 batches of A. pilosa . RESULTS :The extraction technology of A. pilosa extract,which was extracted with hot dip plating using 50% ethanol as solvent ,was optimized. The similarity of 15 batches of A. pilosa was higher than 0.92,and 4 characteristic components were identified(ellagic acid ,quercetin,apigenin,kaempferol). There were significant differences in average extract content and total peak area of characteristic chromatogram of A. pilosa from different origins (P<0.05 or P<0.01),and there was a certain positive correlation between them (r=0.86,P<0.01). Results of entropy weight TOPSIS evaluation showed that the average Ci values of A. pilosa in Anhui ,Zhejiang,Sichuan,Henan and Jiangsu provinces were 0.689,0.351,0.218,0.308 and 0.361 respectively. CONCLUSIONS:The quality of A. pilosa from Anhui was the best ,that from Zhejiang and Jiangsu was better ,that from Henan was the second ,and that from Sichuan was poor. Established extraction technology and characteristic spectrum determination method of A. pilosa are stable and feasible. The entropy weight TOPSIS model is objective and quantifiable for comprehensive quality evaluation of A. pilosa ,and can effectively evaluate its quality.
