OBJECTIVE:To provide reference for promoting smoothly implementation of deprescribing. METHODS:A total of 335 elderly patients with chronic disease were randomly selected from 4 communities and 9 village clinic of a Chongqing community health service center. Questionnaire survey was conducted about general information of respondents,disease and drug use condition and attitude to deprescribing by using Australian Patients'Attitudes Towards Deprescribing questionnaire as reference. The results of questionnaire survey were analyzed statistically. The cognitive function was assessed by Hastgawa Dementia Scale. The degree of weakness was evaluated by Chinese edition of Edmonton Frail Scale. The quality of life was evaluated by Chinese edition of European Five Dimensional Health (EQ-5D) Scale. RESULTS:Totally 311 valid questionnaires were obtained,with effective recovery rate of 92.8％. Overall,311 participants were recruited,with a median age of 70 years,5 types of median disease (hypertension was most common) and 5 types of median medication (mainly calcium channel blocker and non-insulin hypoglycemic agent);54.7％(170 cases)participants took multiple drugs. The attitudes towards deprescribing were that 39.5％ of respondents believed that they took too many drugs;73.9％ had a desire to reduce their drugs;83.6％ reported that they would be willing to reduce drugs if their doctor said it was possible. The patients taking multiple drugs preferred to use less drugs (P=0.001) and reduce current drugs (P=0.001),and were more willing to reduce drug cost by reducing drug use;they were also more worried about drug side effects than those without taking multiple drugs (P=0.005). CONCLUSIONS:The phenomenon of elderly chronic diseases patients with multiple diseases and multiple drug use are popular in community. It is necessary to simpilfy prescription. Most elderly patients would like to reduce their medications if doctors say it is possible;the patients with multiple drug use are more willing to simplify prescription than those without multiple drug use.

OBJECTIVE:To provide reference for the clinical pharmacists to determine their work orientation,and improve their work mode and pharmaceutical care level. METHODS:The questionnaire survey was conducted among doctors,nurses, patients and pharmacists from 65 third grade class A hospitals of 18 provinces(regions,cities)in China. The collected data were analyzed statistically and suggestions were presented. RESULTS:Totally 3 840 questionnaires were sent out,3 045 were effectively received with a recovery of 79.30%[involving 56 third grade class A hospitals of 17 provinces(regions,cities)]. Of 3 045 valid questionnaires,1 001 questionnaires were filled out by the doctors and nurses,1 013 questionnaires were filled by the pharmacists and 1 031 questionnaires were filled out by the patients. 88.45% of the survey doctors and nurses thought that clinical pharmacists were needed in their wards. The major clinical pharmaceutical care they needed were the participation of clinical pharmacists in the clinical ward round,patients management,difficult case discussions,consultation(77.32%),etc. 64.54% of the survey doctors and nurses thought that clinical pharmacists could participate the clinical work and solve some simple medicine-related problems, and 27.17% of the survey doctors and nurses thought that clinical pharmacists could resolve clinical medicine-related problems. 14.59% of the survey doctors and nurses believed that clinical pharmacists lacked clinical thinking and could not communicate with medical staff. The most common problems the survey medical staff met were as follows:ADR (78.02%),usage and dosage(72.83%),contraindications(72.63%),drug indication(63.14%)and solvent selection (61.74%),etc. As regards the ratio of working time which clinical pharmacists spent on their clinical work,over 50%(35.55%)and 30%(23.46%)were most chosen by the survey pharmacists,while 13.19% of the survey pharmacists thought clinical pharmacists almost did not participate in clinical work. The survey pharmacists thought that there were some deficiencies in the knowledge structure of clinical pharmacists, such as clinical medical science and therapeutics(92.50%), communication skills(47.19%),professional knowledge of pharmacy(46.10%),etc. 87.90% of the survey patients were willing to accept the medication guidance provided by clinical pharmacists. The services they required were as follows:medication guidance(79.92%),observation and discovery of medication problem(71.00%),etc. CONCLUSIONS:Medical staff and patients have demands in many ways associated with clinical work and rational drug use provided by clinical pharmacists,while the clinical pharmacists have yet not reached the demands of medical staff and patients in regard to their evaluation. It is suggested that the clinical pharmacists should ascertain their work orientation,improve their work mode,participate the clinical work in full-time, complete their knowledge structure and ascent their pharmaceutical service level.

OBJECTIVE： To investigate the protective effect and its mechanism of thymoquinone （TQ） on myocardial fibrosis （MF） induced by lipopolysaccharide in rats. METHODS： Totally 40 male Wistar rats were randomly divided into control group， model group， TQ low-dose and high-dose groups [5， 10 mg/（kg?d）]， with 10 rats in each group. Except that control group was given constant volume of normal saline intraperitoneally， other groups were given LPS intraperitoneally to induce MF model， once a day， for consecutive 3 weeks. Since the first day of modeling， administration group was given relevant medicine intraperitoneally， once a day， for consecutive 3 weeks. After last medication， ELISA method was used to detect the contents of serum inflammation factors （IL-1β， IL-6， TNF-α） in rats. Cardiac mass parameters （HW/BM， LVW/BW） were weighed and calculated. HE staining was used to observe the histopathological changes of myocardial tissue. The contents or activities of oxidative stress indicators （MDA， SOD） and myocardial collagen indexes （HYP， Col-Ⅰ， Col-Ⅲ） were detected by chemical analysis， xanthine oxidase method or ELISA. mRNA expression of regulation genes （Col-Ⅰ， Col-Ⅲ， MMP-3， MMP-9， TGF-β1 and Smad3） related to myocardial fibrosis were determined by real-time fluorescence quantitative PCR. RESULTS： Compared with control group， there were swollen myocardial cells， disordered nuclei of different sizes and visible fiber hyperplasia in model group； the levels of serum inflammatory factors and LVW/BW， cardiac contents of MDA， HYP， Col-Ⅰand Col-Ⅲ， mRNA expression of Col-Ⅲ， TGF-β1 and Smad3 in model group were increased significantly （P＜0.05）， while SOD activity was decreased significantly （P＜0.05）. Compared with model group， the degree of myocardial fibrosis was improved in TQ groups to different extents； serum content of IL-1β and the contents of MDA， HYP and Col-Ⅰ in cardiac tissue in TQ low-dose group， serum contents of IL-1β， IL-6 and TNF-α， LVW/BW and the contents of MDA， HYP， Col-Ⅰ and Col-Ⅲ in cardiac tissue of TQ high-dose group as well as mRNA expression of Col-Ⅰ， Col -Ⅲ， TGF-β1 in TQ groups were decreased significantly （P＜0.05）. The activities of SOD in cardiac tissue were increased significantly in TQ groups （P＜0.05）. There was no statistical significance in other indexes among groups （P＞0.05）. CONCLUSIONS： TQ can protect against MF model rats to certain extent， the mechanism of which may be associated with the inhibition of inflammation reaction and oxidant stress reaction， and down-regulation of mRNA expression of Col-Ⅰ， Col-Ⅲ and TGF-β1.
