Objective: To compare utility values measured by different instruments. Methods: Different instruments were used to measure utility values in 350 patients who were diagnosed as age-related macular degeneration at the same time. The median of utility values measured by different instruments was regarded as relative standard utility value to process comparison, analysis of variance, correlation analysis and curve estimation. Results: Most differences and correlations among utility values measured by different instruments were significant, as well as equations estimated from relative standard utility value and utility values measured by different instruments, but the degree of fitting was not high. Conclusion: The utility values of the same subject measured by different instruments are quite different. The results of the study could provide correction reference to the utility value measured by single instrument in the absence of absolute standard.

Objective To discuss the clinical effect of using autologous quadriceps tendon fixed by a patellar block as the graft to reconstruct posterior cruciate ligament (PCL ) under arthroscopy on a single-bundle way .Methods We treated 21 patients with damaged PCL using autologous quadriceps tendon fixed by a patellar block as the graft and absorbable interference screw fixation to reconstruct PCL under arthroscopy on a single-bundle way .Their functional recovery was evaluated by Lysholm scoring ,Tegner scoring and International Knee Documentation Committee (IKDC) criteria .Results All 21 patients got successful surgery on PCL reconstruction and multiple trauma ,no patients lost to follow-up .The subjective symptoms were improved after operation ,the post-operative Lysholm score and Tegner score were both significantly enhanced and showed statistical significance compared with the preoperative scores(P<0 .01) .Conclusion Using autologous quadriceps tendon fixed by a patellar block as the graft to reconstruct PCL on a single-bundle way leads to satisfactory short term clinical effects ,however ,the long term clinical effects remain to be eval-uated .

OBJECTIVE:To understand the trend of cost and amount of consumption of antihypertensives,antidiabetics,antipsychotics and antibiotics in Shanghai.METHODS:The data of above-mentioned 4 sorts of drugs were collected from analysis system of drug-use of Shanghai in 1994～1999.The cost of each sort of drug was calculated in term of fixed price of 1994 and the amount of consumption was discount to DDDs.RESULTS:The total cost and total amount of consumption of these 4 sorts of drugs assumed a tendency towards increase and the growth rate of the former exceeded that of the latter.Antibiotics were the highest in cost;antidiabetics and antipsychotics were the highest in growth rate;antihypertensives were maximum in amount of consumption and antidiabetics were the highest in growth rate of consumption.CONCLUSION:In Shanghai,the total cost of these four sorts of drugs increased rapidly and the prices of drugs rose year by year.The spectrum of diseases has changed to some extent.

Objective To find out about the increase in the expenses of drugs as well as the changes of prices, manufacturing costs, and the distribution of profits in the manufacturing process so as to provide basis for the reform and perfection of the control of drug prices. Methods Using the method of retrospective sampling, investigations were made into the prices of drugs extensively used clinically throughout the country from 1995 to 2002 and analyses were conducted into the manufacturing and operating status of 80 pharmaceutical companies in 18 provinces of the nation and profits and other relevant influencing factors in 48 drug wholesaling enterprises in 20 provinces of the nation in 1999. Results The increment speed of the expenses of drugs in the 90s of the 20 th century in China was above 10%, higher than the increment speed of the GDP; the price index of drugs was on overage higher than the general price index; and the complete manufacturing costs of drugs accounted for 54% of their retail prices. Conclusion The prices of drugs in China might be regarded as appropriate, and yet too large an amount of profits goes into the process of circulation, resulting in insufficient funds for the pharmaceutical industry to conduct research and development.

Objective:To analyze the impact of Recombinant Human Tumor Necrosis Factor-α Receptor Ⅱ:IgG Fc Fusion Protein (rhTNFR:Fc) on medical insurance budget.Methods:Rheumatic drugs were select from the IMS data 2015.The drug quantity unit was converted to defined daily dose(DDD).The quantity of rhTNFR:FC in IMS data 2015 was taken as the baseline.The expenditure growth and its impact on rheumatic drugs and all drugs were calculated under 90％ and 80％ reimbursement rate as the different incremental proportion of the quantity of rhTNFR:Fc.National health insurance expenditure data was derived from statistical data of government departments.Results:According to 90％ reimbursement rate,medical insurance expenditure increased by 5.22～10.43 billion yuan.rheumatic drugs and all medical insurance drugs expenditure increased by 63.44～126.87％ and 0.04～0.08％ respectively while the consumption of rhTNFR:Fc increased 0-100％ in 2015.The increment of medical insurance expenditure reduced accordingly under the reimbursement ratio of 80％.Conclusion:The budget impact of rhTNFR:Fc was great on medical insurance expenditure of rheumatic drugs,which was very limited on the medical insurance expenditure of all drugs.
