Objective To investigate the effect of percutaneous nephrostolithotomy (PCNL) on patients with different body mass index.Methods The clinical data of 84 patients with kidney stones who were treated with PCNL surgical treatment were enrolled in this study,and they were divided into different groups according to body mass index (BMI),including 16 cases of BMI ＜ 18.5 kg/m2(low BMI group),36 cases of 18.5 kg/m2≤BMI ＜24.0 kg/m2 (normal BMI group),32 cases of BMI≥24.0 kg/m2 (high BMI group),and the curative effect was evaluated.Results Three groups' operation time,multichannel gravel rate,stones clearance,length of hospital stay,blood transfusion rate had no significant difference (P ＞0.05),the incidence of complications in low BMI group [31.25％ (5/16)] was obviously higher than that in normal BMI group [5.56％(2/36)] and high BMI group [9.38％(3/32)],there was significant difference (P ＜ 0.05).Conclusion BMI of PCNL surgery influences on certain effect,low BMI will affect patients with surgery tolerance,cause complications increase,obesity wifl increase the difficulty of the operation.

ObjectiveLamiophlomis rotate is the rare perfumes Tibetan medicine.This article aimed to explore the current research of Lamiophlomis rotate on the base of literature.MethodsEstablish database of researching literature on Lamiophlomis rotate in domestic published between 2000 and 2010.Results Altogether 210 articles distributed in 112 kinds of journals were found.These articles involved with 8 areas of clinical research(113 article),pharmacological research(18 article),component analysis(35 article),preparation process (15 article),breed and cultivation of seeds (4 article),new drug testing (3 article),biological characteristics and drug economics.32 articles gained fimancial assistance from fund.Three articles on breed and cultivation of seeds gained financial assistance from fund,occupying 75.00％ of such research.Conclusion There were few articles published in core journals,besides relatively scattered distribution of researching institute and journals.Studies on breed and cultivation of seeds should be strengthened.

Objective:To analyze the efficiency and influencing factors of Chinese medical and health resources. Methods:Based on the panel data of 31 mainland provinces from 2003 to 2011 in China, use the two-stage Malmquist-Tobit model to analyze. Results:The efficiency of Chinese medical and health resources shows an increasing trend, which is dual driven by improvement of technical efficiency and technological progress. The efficiency varies among different areas, and the descending order of efficiency value is east, west and center. The level of economic development, population density, the proportion of profitable hospitals, the levels of urbanization and education can promote Chinese medical and health efficiency with different extent. Conclusion:To improve the efficiency of Chinese medical and health resources, it needs to promote economic development level, allocating health resources reasonably, and advancing urbanization and education levels orderly.

Objective To investigate the changes of CRP in diagnosis of the acute exacerbation of COPD and its significance.Method CRP and WBC were measured both when the patients just before and after the treatment with effective antibiotics to compare their change.Results The positive rate of CRP is 85.40%.and the difference Was obvious(P＜0.01).At the same time,the CRP's difference between before and after the use of antibiotics was also obvious(P＜0.01).Conclusion CRP is a sensitive and specific index to the acute exacerbation of COPD,and is helpful to discover this acute disease early as well as a good guide to estimate the serious of pneumonia sand to respond the efficacy of antibiotics.

Objective To investigate the relationship between plasma homocysteine levels and lipids in aged patients with acute cerebral infarction(ACI).Methods Fourty-eight cases(observation group),who had been inpatients with cerebral infarction during May 2006 to May 2007,thirty healthy people(control group)contrasted and analyzed.Results The mean plasma homocysteine level and cholesterol(TC),triglycerides(TG),low density lipoprotein(LDL)of aged patients with acute cereral infarction were significantly,higher than those of the control group,but high density lipoprotein(HDL)was lower(P＜0.01).No significant correlation between Hcy level and TC,TG,HDL-C,LDL-C level in serum.Conclusion Plasma homocysteine lexrel and lipids all siginificantly increased in aged patients with acute cereral infarction,and homocysteinemia is not related with lipids,but is an independent risk factor for cerebral infarction.

Objective To explore the improvement of minocycline on negative symptoms in patients with schizophrenia and its influence on tumor necrosis factor (TNF)-α.Methods Patients with schizophrenia were randomly assigned into two groups.One was olanzapine combined with placebo group (control group, 37 cases).The other was olanzapine combined with minocycline group (treatment group, 200 mg ·d-1,po,bid, 38 cases).Both groups were assessed by the positive and negative syndrome scale (PANSS), the scale for the assessment of negative symptoms (SANS), and also tested the level of TNF-α before and after 12 weeks treatments.Results After 12 weeks treatments, the scores of SANS and PANSS in treatment group were significantly lower than those of control group (P<0.05).The level of TNF-α in treatment group[(6.5±1.3) pg ·mL-1]was significantly lower than that of control group[(7.6±1.8) pg ·mL-1] (P<0.01).Conclusion Minocycline can improve negative symptoms in patients with schizophrenia, and the mechanism may be related to lower the level of TNF-α.

Objective To evaluation the Diagnosis value of single and consociation to drawing materials methods with bronchofibroscopy in pulmonary carcinoma.Methods 481 diagnosed patients with pulmonary carcinoma by bronchofibroscopy during July 2000 to July 2006 were analyzed.Four different drawing materials method including clamping,brushing,needling and rinse checking were used to diagnose.The positive rates of these four methods were compared with single and consociation to drawing materials methods.Results The positive rate of clamping,brushing,needling and rinse checking were 83.9%,70%,59.1%and 35.9%respectively,and the total positive rate was 90.2%after being united.Conclusions Bronchofibroscopy is one of the most important methods in diagnosing pulmonary carcinoma. Using multiple drawing materials methods in bronchofibroscopy can improve the accuracy rate of diagnosis of lung cancer significantly.

Objective To observe the effects of Biejia Jian (BJ) in preventing rat hepatic fibrosis. Methods Rat models with hepatic fibrosis were established by abdominal subcutaneous injection of 45 %carbon tetrachloride (CCl4) and olive oil. Fifty Wistar rats were randomly divided into 4 groups: model group (treated with normal saline),small-dosage BJ group (6.25 g/kg BJ), moderate-dosage BJ group (12.5 g/kg BJ) and large-dosage BJ group (25.0 g/kg BJ). The treatment lasted 10 weeks. On the 11th week, rats eyes were removed to get blood sample. The biochemical parameters of blood were detected and HE staining was applied for the pathological examination of liver. Results BJ decreased the serum levels of ALT,AST,HA, LN and PC III in rats, no pseudo-lobules found in the BJ groups. Proliferation of fibrous tissue was mild and Limited and fatty degeneration of hepatocytes were slight in moderate-dosage and high-dosage BJ groups as compared with the small-dosage BJ group.Pathological changes in BJ groups were significantly improved (P

OBJECTIVE To evaluate the bioethical principles which should be followed in the epidemiological study of AIDS.METHODS Practicality of bioethical principles in epidemiological study of AIDS was evaluated by theoretical analysis method.RESULTS The important principles in the epidemiological study of AIDS are respect,beneficence/nonmaleficence and justice principles.CONCLUSIONS Following bioehical principle is the basis of epidemiological study of AIDS.
