OBJECTIVE:To probe into the status quo and the tendency of the utilization of the anti-osteoporosis drugs in hospitals along the Yangtze valley. METHODS: The utilization of the anti-osteoporosis drugs in 177 hospitals of 6 cities along the Yangtze valley during 2004～2008 was analyzed statistically in respect of the orders of consumption sum and defined daily dose (DDD). RESULTS: The total amount of the drugs used for osteoporosis in the hospitals of the Yangtze valley showed year-on-year increase,and its proportion in the total remained at around 1.16% on the consumption sum list. The consumption sum of Diphosphonates showed sharp increase,many of its subcategories had forced into the top 10 places on the list of consumption sum and their rankings were moving forward steadily. Alfacalcidol and Calcitonin dominated the first two places over the 5 years. The top 10 manufacturers in terms of the sales sum of the drugs for osteoporosis were mainly foreign investment manufacturers and joint ventures. CONCLUSION: With the aging of the population and the strengthening of public awareness on health,the drugs used for osteoporosis enjoy a potential market,especially to domestic products and domestic manufacturers.

OBJECTIVE:To study the release characteristics of Evening primrose oil microspheres in vitro. METHODS:UV spectrophotometry was adopted to determine the accumulated release of microspheres under different media,and the drug release behaviors in vitro were fitted using zero-order,first-order and Higuchi equations. RESULTS:The accumulated release of microspheres in the gastrointestinal liquid (within 6 h) was up to(92.84?0.35)%;under the media of artificial gastric juice,the release of drug conformed to Higuchi equation:Q=5.941t1/2—11.083(r=0.991 7); under the media of artificial intestinal juice,the release of drug was in line with first-rate equation:ln(100—Q)=—0.487 4t+4.588(r=0.996 4). CONCLUSION:This method is simple,accurate and reproducible,and it can be used for the determination of the release rate of the Evening primrose oil microspheres.

OBJECTIVE:To analyze clinical efficacy and safety of pioglitazone combined with metformin in the treatment of type 2 diabetes.METHODS:102 patients with type 2 diabetes were randomly divided into 2 groups.Treatment group received pioglitazone combined with metformin and treatment group received metformin alone.The levels of blood glucose and insulin were observed and compared between 2 groups.RESULTS:After 6 months of treatment,fasting plasma glucose(FPG),postprandial 2 h blood glucose(P2hBG),glycosylated hemoglobin(HbA1c),fasting insulin(FINS),postprandial 2 h insulin(P2hINS),steady-state assessment index of insulin(HOMA-IR) in 2 groups were significantly decreased,there was statistical significance in difference before and after treatment(P

Objective The various influencing factors in the process of nano-silver preparation were studied in order to prepare nano-silver that has uniformity particle size distribution and good crystallinity. Methods Through the method of liquid reduction at room temperature,the nano-silver powders were prepared directly using silver nitrate as raw material,water as the reactive medium,polyvinylpyrrolidone(PVP) as protecting agent and ammonium formate as reducing agent. By means of EDS and TEM(transmission electron microscopy),the prepared silver particles were characterized. The various influencing factors in the process of preparation were also discussed. Results With the increasing concentration of AgNO3,the particle diameter of nano-silver changed obviously. When the concentration of silver nitrate was 0.25-0.30 mol/L,the size of product is the smallest. With the increasing concentration of reductant,the diameter of nano-silver decreased gradually. While at the concentration of 0.70 mol/L HCOOH,the average diameter of nano-silver is not more than 10 nm. Smaller and more well-distributed silver powder could be prepared at ratio of concentration of PVP to AgNO3 with the value of 1.5-1.0,at which PVP presented effective protection. Conclusions This method can prepare particle of nano-silver which revealed well dispersed and uniform size. The process is stable and reliable,easy to operate,high yields and suitable for industrial production.

This research applied the theory of customer satisfaction model in the evaluation of the clinical information system. By means of qualitative and quantitative methods, it made validity and reliability measurement on the measurement tools in use. In addition, it extracted the structure validity of the factor regulating scale via a factor analysis, and developed the scale for clinical information system measurement These efforts provided the hospitals with the useful measurement tool to improve their information system, promoting positive and practical hospital informationziation.
