Objective To compare the lipid lowing effect and the clinical safety between intensive therapy with Chinese medicine Zhihitai and atorvastntin in patients with moderate and high risk of atherosclerosis. Methods All the patients were randomly divided in to a Zhibitai group (n = 85) receiving 480 mg of Zhibitai orally twice a day or an atorvastatin group (n = 84) receiving 10 mg atorvastatin orally once daily. Blood lipoproteins, myocardial enzymes, fiver and renal function were measured before treatment and at the fourth and eighth week after therapy , while high sensitive creactive protein (hs-CRP), P-selectin, matrix-metall proteinase-9 (MMP-9) and soluble intercellular adhering molecule-1 (SICAM-1) were detected before treatment and eighth week after therapy in all patients. Results TC and LDL-C were significantly decreased while HDL-C was increased in both groups after 4 and 8 weeks treatment (P < 0. 05). TG was decreased in Zhibitai group after 4 and 8 weeks of treatment, but it was decreased in atorvastatin group only after 8 weeks of treatment. Inflammatory factors such as hs-CRP, P-selectin, MMP-9, SICAM-1 were decreased significantly (all P < 0. 01), but there was no significant difference between the two groups. There were no difference in liver and kidney function, myocardial enzymes and incidence of muscle-ache and digestive system side reaction. ConclusionsBesides the lipoprotein disorder, inflammatory factors in patients with moderate and high risk of atherosclerosis could be regulated with intensive therapy of Zhibitai. Most importantly, it is safe to use Zhibitai clinically.

Purpose:To study the expression of COX 2,P53 and PCNA in esophageal carcinomas and its significance. Methods:Immunohistochemical method was used to examine the sections from 82 esophageal squamous cell carcinomas, 20 esophagitis and 16 normal esophageal mucosa tissues. Results:The positive ratios of COX 2,p53 and PCNA were 87.8%(72/82),82.9%(68/82)and 95.1%(78/82) in 82 esophageal carcinomas, respectively. But there was no expression in adjacent noncancerous tissues and normal esophageal mucosa tissues. The positive ratio of COX 2 protein was significantly higher in the well differentiated and moderately differentiated esophageal carcinomas than in the poorly differentiated esophageal carcinomas( P

Objective To detect the expression of KiSS-1, KiSS-1R and MMP-9 in hepatocellular carcinoma (HCC). To study the correlation of KiSS-1, KiSS-1R and MMP-9 expression with invasion and metastasis of HCC, and to explore the underlying mechanisms. Methods The expression of KiSS-1 , KiSS-1R mRNA in 33 HCC samples, 26 non-neoplastic adjacent liver tissue samples and 13 non-neoplastic distant liver tissue samples were detected by RT-PCR. Tissue chips were constructed by modified manual tools, which contained HCC, non-neoplastic adjacent liver tissues, non-neoplastic distant liver tissues, normal liver tissues and intrahepatic metastasis lesions. The expression of KiSS-1 and MMP-9 protein was determined by tissue chips, immunohistochemistry and semi-quantitative image analysis in 150 HCC, 137 non-neoplastic adjacent liver tissue, 98 non-neoplastic distant liver tissues, 16 normal liver tissues and 37 intrahepatic metastasis lesion samples. Results The results of RT-PCR showed that compared with the non-neoplastic adjacent liver tissues and the non-neoplastic distant liver tissues, the expression of KiSS-1 mRNA in HCC was significantly lower (P＜0.01). The expression of KiSS-1R mRNA did not changed in HCC and non-neoplastic liver tissues (P＞0.05). The expression of KiSS-1 protein was lower in HCC with metastasis and in clinical stage Ⅲ than that in those with non-metastasis, and in clinical stages Ⅰ and Ⅱ . It was also higher in the primary than in the metastasis lesions (P＜0.01, respectively). The expression of MMP-9 was higher in tumors having peplos invasion and metastasis than in those with negative peplos invasion and non-metastasis. It was lower in the primary than the metastasis lesions (P＜0. 01, respectively).Negative correlation between KiSS-1 and MMP-9 expression was found in HCC(r=- 0.340,P＜0.01). Conclusions The imbalance between KiSS-1 and MMP-9 expression might play an important role in enhancing the invasive and metastatic capacity of HCC. Loss of KiSS-1 expression might predict an aggressive clinical behavior and was associated with metastatic potential in HCC.

Objective To explore the potential role of apolipoprotein A5 (ApoA5) on the hypertriglyceridemia (HTG)-lowering effects of statin. Methods Twenty-four Sprague-Dawley rats were assigned to 3 groups:(1)control group, with no special treatment. (2) HTG group, treated with 10% fructose water for 6 weeks. (3) statin 4 weeks. Body weight, fasting plasma lipids, and the hepatic expressions of ApoA5 and PPARα were determined. In separate in vitro experiments, the effects of atorvastatin on triglyceride (TG) and the expressions of ApoA5 and PPARα in HepG2 cells were tested. Results (1) Plasma TG was higher in HTG group than in controls group, which was significantly reduced in statin group (both P ＜ 0. 05). (2) Rat hepatic ApoA5expression in HTG group was significantly lower than in control group and it was significantly higher in statin group than in HTG group (both P＜0. 05). (3) Similarly, rat PPARα mRNA expression in HTG group was lower than in control group and it was higher in statin group than in HTG group (both P ＜ 0.05). (4) Statin significantly upregulated the expressions of ApoA5 and PPARα and decreased TG in HepG2 cells, which was blocked in the presence of PPARα inhibitor. Conclusion Upregulation of ApoA5 expression contributes to TG lowering effect of statin via PPARα signaling pathway.

OBJECTIVETo study the effects of different doses of fertilizer N,P and K and different plant densities on the growth of Artemisia annua and the yield of artemisinin which provides a scientific basis for the A. annua cultivation and artemisinin production.

METHODField experiment with an orthogonal experimental design L16(45) was applied.

RESULTN, P and K in moderate supplies increased significantly total biomass, leaf yield, artemisinin content in leaf and artemisinin yield under both per plant and per plot, with N and K having more effective on the artemisinin content in leaves than P. Ample N benefited the formation of leaf yield, but excess N had a significant negative effect on artemisinin content. Extra supply of P or K had hardly obvious father positive efficiency, nor negative on artemisinin content. The plant density had strong negative effects on total biomass, leaf output and artemisinin yield of single plant (per plant), but obvious positive effects on the same indices of population (per plot) with the moderate densities due to the enlarging numbers of the population; over crowded density significantly decreased artemisinin content and artemisinin yield per plot. By multiple comparison, the treatment 12 (N3P4K2 density 3) which produced the highest yields of artemisinin and artemisinin-rich leaf per plot was selected as the best in the experiment.

CONCLUSIONFertilization quantities of N, P and K fertilizer and moderate density were essential for A. annua growth and artemisinin production. The optimal application of N, P and K were respectively 300 (N), 150-300(P2O5), 210(K2O) kg x hm(-2) and the optimum density was 25 000 plant x hm(-2) nearby the test area in Chongqing.

Objective To investigate the spatial distribution and growing trend of 438 human infection with the H7N9 avian influenza virus in mainland China,and to provide evidence for developing scientific prevention and control strategies.Methods 438 human infection with the avian influenza A (H7N9) cases from February 2013 to May 2014 in mainland China were studied and data collected to establish a database for the development of geographic information system.Trend surface analysis and spatial autocorrelation analysis were used to study the spatial distribution.Descriptive epidemiological method was utilized to analyze the demographic characteristic.Results From June 2013 to May 2014,cases had an overall national increase,but significantly decreasing in Shanghai.A trend surface was established for human infection with avian influenza A (H7N9) in the mainland of China,showing that the incidence was increasing obviously from north to south and the line slope declined from west to east.Distribution pattern of the cases varied within different time series and regional levels.The overall Moran' s I coefficient of the provincial level from February to May in 2013 and the coefficient of the city level from June 2013 to May 2014 were 0.144 718 and 0.117 468,respectively,with the differences statistically significant (P＜0.05).According to the analysis of the local autocorrelation and hot spot,northern Zhejiang and southern Guangdong showed high spatial clusters of human infection with avian influenza A(H7N9) (Z＞2.58).Conclusion From February 2013 to May 2014,the spatial correlation at the provincial level decreased.However,the spatial correlation and the numbers of hot spots at the city level were both increasing.Effective measures should be taken accordingly,following the distributive characteristics.

Objective To explore the relationship between the renal dysfunction rate and metabolic syndrome(MS),stratified by age. Methods People took part in physical check-up in a certain tertiary hospital from March 2010 to September 2012,were enrolled in this study. Estimated glomerular filtration rate(eGFR),-a renal dysfunction indicator,was calculated by modified MDRD equation[<60 ml/min(1.73 m2)]. Associations between the renal dysfunction rate and factors as age,gender and MS traits,were assessed by stratified analysis. Results Eligible data from 75 469 subjects were used. The prevalence rates of renal dysfunctions appeared to be 0.05%,0.20%,1.68%in 18 to 44 year-olds(youth),45 to 59 year-olds(middle)and 60 year-olds or above(old),respectively. Participants with MS showed a significantly higher risk than those without,in the elderly only(P<0.05)but not in the other 2 groups(P>0.05). Participants with 2 components of MS in middle-aged, 3 or 5 components of MS in the elderly showed a significantly high incidence (P<0.05),but no significant differences seen in other subgroups(P>0.05). Increasing trend was not seen in all the 3 groups(P>0.05). Elevated blood pressure(BP+)in youth and middle-aged groups,decreased high density lipoprotein(HDL-C)in middle-aged and elderly groups and elevated fasting plasma glucose (FPG+)in elderly group could all cause the abnormality rate of eGFR which showed significantly high incidence rates in the subgroup analysis(P<0.05). The maximum of population attributable risk proportion (PAR%) was 41.91% in youth when having elevated BP. Relationship between renal dysfunction rate and triglyeride(TG)/obesity was not identified. Conclusion The prevalence of renal dysfunction was found low,in Xuzhou. The incidence was not associated with the numbers but might relate to the nature of certain components of MS. Increased BP showed both short-term and mid-term effects. Decreased HDL-C,however,indicated both mid-term and long-term effects. The elevated FPG only appeared long-term effects. Increased TG and obesity did not show significant effects in these observed samples. PAR%of increased BP seemed to be the most important factors which might lead to renal dysfunction.
