Objective To observe the effect of lattice silver wound repair dressings on large-area abrased wounds . Methods A total of 60 patients with large-area skin abrasions were randomly divided into the observation group and the control group with 30 cases in each group. Both groups were treated with the same antibacterial treatment and nutritional support treatment. The control group received conventional general routine dressings and the observation group had the silver wound repair dressings every day. The two groups were compared in terms of the wound pain, wound infection rate, time for wound healing and scars of patients. Results The wound healing time in the observation group was significantly shortened (P<0.01). The scaring of the observation group was better than that in the control group (P<0.01). The pain degree and the exudation rate were both significantly lower in the observation group than those of the control group (P<0.01), and wound infection rate was lower than that of control group. Conclusions The lattice silver wound repair dressing can effectively promote the wound healing, shorten hospitalization duration, promote the patient recovery soon. It is simple and worthy of clinical popularization.

OBJECTIVE:To provide reference for further improving negotiation mechanism of drug medical insurance in Chi-na. METHODS:Questionnaire investigation was conducted among the medical insurance agency and pharmaceutical company staff who participated in drug medical insurance negotiation in Jiangsu province,Jiangxi province,Qingdao,Chengdu. Their business fa-miliarity and recognition of the negotiating mechanism were also investigated. The descriptive analysis,independent sample t test and other methods were adopted to analyze the data statistically. RESULTS:A total of 70 questionnaires were distributed and 68 val-id questionnaires were collected with effective recovery rate of 97.14%. Respondents included 21 staff members of medical insur-ance agencies and 47 of pharmaceutical companies. In terms of business familiarity,the average score of respondents in all aspects was greater than 3(4 points system),the lowest score wasmanagement of the implementation of drug negotiation projects. There were statistical significances in scores of 3 items between 2 parties in the negotiation(P<0.05):basic principles of the drug negotiation process should be followednegotiation objectives in the substantive negotiation process total score of busi-ness familiarity. The scores of respondents in pharmaceutical companies were higher than those of health insurance agencies. In the recognition of the negotiating mechanism,average score of each survey item was ≥4(5 points system)in the recognition of the overall effect of the negotiation mechanism except forwhich is conducive to maintaining the price system of pharmaceutical com-panies. The average score of all aspects of preparation of the negotiations,substantive negotiation,implementation of the negotia-tion agreement and negotiation project's supervision and evaluation was >4 except forpatients taking drugs is quick and easy. There was no statistical significance between 2 types of respondents in all aspects of overall effect of the negotiation mechanism, preparation of the negotiations and negotiation project's supervision and evaluation(P>0.05). But in the recognition of the substan-tive negotiation,there was statistically significance between 2 types of respondents innegotiations between the two sides in an equal,cooperative,harmonious atmosphere(P<0.05). Healthcare agencies'respondents had higher scores than pharmaceutical companies'ones. And in the recognition of the implementation of the negotiation agreement,there was statistical significance be-tween 2 types of respondents in theafter the agreement entered into force,the medical insurance agency will be strictly in accor-dance with the agreementandfund pay to pharmaceutical companies timely and reasonable(P≤0.05). Healthcare agencies're-spondents have higher scores for than pharmaceutical companies'ones. CONCLUSIONS:The current drug medical insurance nego-tiation mechanism shows good overall effect and runs smoothly. But there are still some shortages,such as collected information the preparation stage is not sufficient;the procedures of patients taking the drug is complicated;negotiating parties do not have equal status;the fund is not paid to the pharmaceutical enterprise timely;evaluation is not perfect.

OBJECTIVE:To know the status quo of clinical pharmacy in main hospitals of Jiangsu province primarily,and to provide reference for promoting the construction of clinical pharmacist system and playing active role of clinical pharmacists on rational drug use and pharmaceustical care.METHODS:A mailed questionnaire investigation was conducted among 28 committee members (coming from 28 hospitals) of the Clinical Pharmacy Branch of the Medical Association in Jiangsu Province regarding the status quo of the clinical pharmacy practice,and the correlated data and results were summarized to statistical analysis.RESULTS:A total of 28 questionnaires were distributed and 28 valid questionnaires were collected,with recovery rate of 100％.Among 28 hospitals,there were 25 general hospitals and 26 third grade class A hospitals.There were 312 full-time and part-time clinical pharmacists;there were 7.32 full-time clinical pharmacists and 3.82 part-time clinical pharmacists in each visited hospital;the proportion of full-time clinical pharmacists with master's degree and intermediate title was significantly higher than that of part-time clinical pharmacists (P＜0.05).There were 144 full-time clinical pharmacists who had been trained to obtain clinical pharmacists qualifications (70.24％).In 13 hospitals with the qualification of clinical pharmacist training base of National Health and Family Planning Commission (NHFPC),the average number of teachers was 3.77;in 5 hospitals with the qualification of provincial clinical pharmacist training base,the average number of teachers was 5.80;in a hospital with the qualification of clinical pharmacist training base of NHFPC,the number of teachers was 5.The surveyed hospital had the highest proportion of clinical pharmacy related work to participate in daily physician rounds,doctor's advice and prescription review,special review of antibiotics,drug record writing,pharmaceutical information service,outpatient drug consultation and ADR monitoring,all being 100％.Expert consultation clinic occupied the lowest proportion of clinical pharmacy work (10.71％).Setting up pharmacy for operation and anaesthesia department (28.57％),community pharmaceutical care (57.14％),pharmacogenomic testing (46.43％) and participating in the management of drug clinical trials (53.57％) occupied the lower proportion of clinical pharmacy related work.The proportion of clinical pharmacy work in training base hospital was higher than that non-training base hospital.Compared to surveyed hospitals,there was statistical significance in the proportion of special review for antineoplastic drugs,hormone drugs and blood products,expert consultation,setting up pharmacy for operation and anaesthesia department,community pharmaceutical care,pharmacogenomic testing and participating in the management of drug clinical trials in provincial clinical pharmacist training base (P＜0.05).There was statistical significance in the number of specialist consultation,case analysis,inpatient injection medical orders,check pharmacy intravenous admixture medical orders and checked outpatient prescriptions,varieties and number of monitored therapeutic drugs as well as case number of pharmacogenomic testing (P＜0.05).CONCLUSIONS:It is suggested to strengthen the construction of clinical pharmacist team in third grade class A hospital in Jiangsu province,accelerate the transition of part-time clinical pharmacists,at the same time,further improve the development of clinical pharmacy related work.

The accurate location of acupoints is the prerequisite for the efficacy of acupuncture-moxibustion. Bone-length measurement, bone-proportional measurement, and proportional unit of the body measurement are commonly used in clinic for acupoints location. Based on the systematic review of the ancient literatures, this article discussed the meaning, evolution and relations of bone-length measurement, bone-proportional measurement, and proportional unit of the body measurement. It’s concluded that the bone-length measurement should be a benchmark in ancient anthropometry and an important basis for acupoints location. Bone proportional measurement, used in different genders, ages and body sizes, was based on the relatively stable proportional relations of various body parts, though some of the standards were adjusted in accordance with the correlation between meridians and acupoints. Location of points by proportional unit of the body simplified the application of bone-length measurement and bone proportional measurement, based on the ratio between short and long bones or the ratio of same body parts in anthropometry. However, proportional unit of the body measurement should be applied for the specific body parts. Bone-length measurement, bone-proportional measurement, and proportional unit of the body measurement are correspondingly the benchmark measurement, relative measurement, and simplified measurement.
