Objectives To evaluate the effectiveness of ARB in antihypertensive therapy and judge whether it can also protect cardiovascular. Methods A randomized double-blinded placebo-controlled study was used to survey over ten thousand patients in ARB clinical practices. The primary endpoint was stroke, acute myocardial infarction, heart failure, deadly cardiovascular diseases, total mortal. The results were given comprehensive analysis and statistical processing. Results In LIFE study, ARB was more effective than ?-blockers and ARB had the role of protecting the cardiovascular besides lowering the blood pressure. But the VALUE study showed that ARB was not more effective than Besylate. Conclusion There is no obvious distinction between ARB and the other drugs in reducing the blood pressure.

Objective:To study the teeth of the ancients in Xia Dynasty,the first dynasty in Chinese history about 4 000 years ago,and acquaint ourselves with their incidences of periodontal disease,and the evolution of oral diseases.Methods:The teeth and jaws excavated in Erlitoou,Henan Province and Youyao,Shanxi Province were observed with clinical methods.The specimens totaled 56 individuals(male 38,and female 18),including 894 teeth,and 86 dental arches.The objects were all permanent teeth.The major observation items were periodontal disease.The prevalence of periodontal disease of the people in Chinese Xia Dynasty were outlined.Results:The prevalence rate of periodontal disease was 19.80% in the 894 teeth,while prevalence rate was about 42.86% among the individuals.The premortal tooth lossrate was 7.45% in the observed teeth.Conclusion:Periodontal disease is an aging-related disease without sex difference and commonly seen in the mandible,which is quite similar to the situation at present.The periodontal disease was the main reason for tooth loss in people of Xia Dynasty.

Objective To study pathological feature of sacroiliitis of spondyloarthropathies (SpA) in different stages,and improve the threshold of early diagnosis of SpA.Method Samples of sacroiliac joints (SIJ) of 8 patients with ankylosing spondylitis (AS) and 5 patients with undifferential spondyloarthropathies (uSpA) were taken when SIJ steroid injection was performed.The pathological feature was studied.Results Synovitis,including lining cell hyperplasia and inflammatory cell infiltration in looseconnective tissue,local cartilage degeneration,fibrosis and inflammatory cell infiltration in subchondral bony plate and marrow cave were found in 6 (86%,6/7) samples in patients with normal/suspectable SIJ CT scan.In the CT Ⅱ and Ⅲ degree sacroiliitis,marked degeneration and fibrosis of cartilage,inflammatory cell infiltration,pannus formation and subchondral bony plate destruction were increasingly prominent.In the advanced sacroiliitis (CT Ⅳ degree),destruction and calcification of cartilage and subchondral bony plate were the major feature.Eosinopil (EO) was increased in the infiltration cells of synovium and subchrodral bony plate in 3 samples.Conclusion Synovitis,including hyperplasia of lining cell and the infiltration of inflammatory cell in loose connective tissue,and local cartilage degeneration and inflammatory cell infiltration,and destruction of subchondral bony plate are the early changes identified in sacroiliitis.Pathological examination can improve the threshold of early diagnosis of sacroiliitis in case it cannot be confirmed with CT scan.

To study the pharmacokinetics of 5 FU after splenic artery(IA) and auricular vein(IV) infusion, portal vein blood was collected for measurement to appraise the clinical value of treatment with this anti tumor drug via different routes on malignant hepatic neoplasms. 5 FU in portal vein blood was measured with high performance liquid chromatography. The results showed that the concentration of 5 FU in IA group was higher than that in the IV group. The peak concentration of 5 FU in the IA group was higher than that in the IV group by 64%. The area under the curve (AUC) of 5 FU in the IA group was larger than that in the IV group by 42%. It suggested that higher concentration of anti tumor drug in the portal vein could be obtained via splenic artery infusion, and it is valuable for the treatment of malignant hepatic neoplasms.

Objective To analyze the present situation of technical efficiency in TCM hospitals throughout the country, discuss the influencing factors causing inefficiency and propose corresponding suggestions. Methods The technical efficiency in 60 TCM hospitals in the country was analyzed using the stochastic frontier cost model for panel data and the influencing factors causing inefficiency were discussed using the multiple stepwise regression method. Results The average technical inefficiency was 22.59% and inefficiency showed an upward trend as the areas shifted from the eastern through the middle to the western regions. Five factors, including the utility rate of beds and the proportion of health technicians among the entire hospital staff, were statistically significant so far as the effect on the increase of the overall cost was concerned. Conclusion The stochastic frontier cost model for panel data is the best method for evaluating the technical efficiency in TCM hospitals. On the basis of the above analysis, suggestions for strengthening scientific management, improving the utility rate of resources and reducing unnecessary waste are put forward.

Objective We reported 16 eosinophilic fasciitis (EF) patients with eosinophilic fasciitis and performed a systematic review of the literature to improve the disease awareness.Methods The clinical course of 16 patients with eosinophilic fasciitis at the Peking Union Medical College Hospital were described,inclu-ding demographic data,clinical manifest-ations,laboratory tests,pathology and treatment.Results The mean age at diagnosis was (47±8) years,with 13 female and 3 male patients.Three cases had exertion or strenuous sports before the onset of EF.Positive ANA was noted in 6 of 12,positive RF was noted in 3 of 10,hyper-gammaglobulinemia was noted in 6 of 7,elevated IgG was noted in 8 of 13,peripheral blood eosinophilia was noted in 10 of 16,while thrombocytopenia was found in one patient.Conclusion Based on this and other reported cases in the literature,EF may be a kind of autoimmune disease.Genetic influence and environ-mental factors are involved in the development of this disease.Systemic involvement is rare.In general,corticosteroids and immunosuppressive are effective in EF.
