Objective To detect DNA damage of peripheral blood lymphocytes in patients and family members of autosomal dominant polycystic kidney disease (ADPKD),and to study the effect of irradiation on genomic stability of lymphocytes. Methods Before and after 0.5 Gy radiation dose,single-cell gel electrophoresis (SCGE) was employed to analyze DNA damage of lymphocytes in 10 ADPKD patients (group A),3 members without clinical symptoms of a ADPKD family (group B) and 20 healthy control people (group C).The damage was estimated based on the content of DNA in tail (TDNA％) with comet analysis software (CASP). Results Both before and after irradiation,the TDNA％ (8.85％±0.14％,14.84％±0.77％) and the value-added (6.00％±0.77％) of TDNA％ of group A were significantly higher than those of group C (7.50％±0.37％,12.46％±0.26％,4.96％±0.44％) respectively.There were no significant differences between group B and group C or group A and group B.While 1 person in group B had higher TDNA％ as compared to group C both before and after irradiation. Conclusions The lymphocytes of ADPKD patients are more sensitive to ionizing radiation as compared to healthy people.The genomic instability in ADPKD patients or member of ADPKD family may trigger cystic formation in multi-organs when exposing to environmental agents. SCGE may provide a new approach to elucidate the pathogenesis and prognosis of ADPKD.

Objective To describe the distribution of body mass index (BMI) and evaluate the prevalence of overweight and obesity among first to sixth graders in 8 Chinese provinces.Methods Data came from the baseline survey of the Chinese Center for Disease Control and Prevention (CDC) funded project Study on Intervention Models for Main Chronic Diseases among children in China.A stratified random cluster sampling strategy was used to select study participants in 8 provinces,including Inner Mongolia,Jiangsu,Anhui,Shandong,Hunan,Guangxi,Gansu provinces,and Chongqing,with diverse geographical and economic level distributions in China.Counties in each province were stratified into three strata according to economic level,and one county was selected systematically from each stratum.In each county,one urban and one rural elementary school were randomly selected ; and in each school,2-3 classes were randomly selected from each of 1-6 grades.All students in these selected classes were invited for participation.Physical examination was performed by trained local CDC staff using standardized instruments to measure height and weight.Overweight and obesity were diagnosed based on the BMI classification standards for Chinese children and adolescents by Working Group for Obesity in China (WGOC).Results A total of 26558(14225 boy,12333 girl) students aged 6-12 years eventually participated in 8 provinces.The average age was 9.3 ±1.8 years old.Mean BMI among boys (17.0 kg/m2) was higher than that among girls (16.4 kg/m2,t =19.60,P＜0.01).There were statistically significant differences in mean BMI of each age group of boys and 6-11 age groups of girls between urban and rural regions and among those with three economic levels (P＜0.05).The 85th and 95th percentiles of BMI among boys aged 7-11 years in urban region were higher than BMI reference in the standards from WGOC.Lower percentiles were observed among girls aged 7-12 years in rural region.The prevalence of overweight and obesity were 9.3％ and 6.5％ among schoolchildren aged 7-12 years.The prevalence of overweight among boys (10.9％) was higher than that among girls(7.6％,x2 =88.89,P＜0.01) ; while prevalence of obesity were 8.0％ among boys and4.7％ among girls,respectively (x2 =107.17,P＜0.01).The prevalence of overweight was 11.3％ in urban and 7.4％ in rural children(x2 =131.94,P＜0.01).The prevalence of obesity was 8.7％ in urban and 4.3％ in rural children(x2 =188.99,P＜0.01).The prevalences of overweight were 10.3％,8.6％ and 9.0％ in individuals with high,medium,and low economic levels,respectively(x2 =10.76,P＜0.01) ; while the prevalences of obesity were 8.2％,5.6％,and 5.4％,respectively (x2 =51.71,P ＜ 0.01).Conclusions The overall prevalence of overweight and obesity in Chinese school children was high.The prevalence in urban region with high economic level was significantly higher than that in rural region with middle and low economic level.The nutritional and behavioral intervention programs are needed to control the rising trend of obesity in children.

Objective To detect the role of differentially expressed microRNA (miRNA) in human cholangiocarcinoma and explore their effects on apoptosis and invasiveness of cholangiocarcinoma.Methods The differential expression of miRNA in 3 cholangiocarcinoma patients was detected by miRNA array.The expressions of miR-200a,miR-200b,miR-200c,and miR-141 in human cholangiocarcinoma tissues and normal bile duct tissues were detected by real-time PCR.After transfection with miR-200b mimic,apoptosis and invasiveness of human cholangiocarcinoma cell line QBC939 was evaluated by Annexin-V-FITC dyeing and Transwell assay.Results Comparad with normal bile duct tissues,the number of differential miRNAs in cholangiocarcinoma was 21,including 15 up regulated and 6 down regulated.The expressions of miR200a,miR-200b,miR-200c,and miR-141 in human cholangiocarcinoma tissues were significantly lower than levels in normal bile duct tissues.The invasive ability of QBC939 was decreased after miR-200b mimic transfection.The apoptosis cell number of QBC939 was increased after miR-200b mimic transfection.Conclusion These results indicate that the expression of miRNA is different between cholangiocarcinoma and normal bile duct tissues.Moreover,miR-200a,miR-200b,miR-200c,and miR-141 are likely involved in the invasion and metastasis of cholangiocarcinoma and have potential as a diagnostic and prognostic marker.

Oleanolic acid has a widespread pharmacologic effect,including anti-inflammation,antitumor,anfidiabetes,anti-atherosclerosis,hepatoprotection,anti-osteoporosis,etc.Bioavailability of oleanolic acid by oral administration is low,and is absorbed by intestine through passive transport.Oleanolic acid dispersion preparation can increase its solubility and bioavailability,and concentrate on liver to help treat for hepatic disease.The pharmacokinetic parameters,process in body of oleanolic acid,and the pharmacokinetic feature of oleanolic acid dispersion and its prodrug are reviewed,and its research advance on pharmacokinetics is summarized,which provides a reference for rational utilization of oleanolic acid.

Ursolic and oleanolic acids antagonize ox-LDL-,C-reactive protein-,non-enzymatic glycation end products-,hyper-glucose-,H2O2-,lipopolysaccharide-induced endothelial cell injury,and their vascular pharmacologic effects are in many ways.Ursolic and oleanolic acids can inhibit the proliferation of vascular smooth muscle cells,and antagonize serum-,ox-LDL-,hyper-glucose-,leptin-induced vascular smooth muscle cell proliferation,thus produce vascular protection and improve vascular function;Ursolic and oleanolic acids can relieve diabetic vascular complication in diabetic mellitus rats,and vascular stenosis induced by carotid balloon catheter injury,and suppress the proliferation of vascular adventitial fibroblasts and prevent vascular stenosis induced by various experimental atherosclerosis models;they can also inhibit the proliferation of vascular endothelial cells,and have a dual action to antagonize inhibiting or promoting proliferation induced by various injurious factions.Thus they have a dual role of regulation in angiogenesis,and suppress angiogenesis of cornea,diabetic retina,and tumor tissues,have effects of vascular relaxation and resistance decrease,and have hypotensive effects in normal and various hypertensive animals.

Objective To observe the effects of Jianpi Huoxue Prescription on the subcutaneous transplantation of tumor cell apoptosis and angiogenesis; To discuss its possible mechanism of action. Methods SMMC-7721 hepatoma mice models were established. 60 tumor bearing male mice were randomly divided into blank group, model group, 5-Fu group, Jianpi Huoxue Prescription high-, medium- and low-dosage groups, with 10 rats in each group. Model group and Jianpi Huoxue Prescription high-, medium- and low-dosage groups were given medicine with relevant concentrations for gavage, once a day. 5-Fu group was given 5-Fu for intraperitoneal injection every other day. The weight, tumor weight and tumor inhibitory rate of each group were compared two weeks later. The protein expressions of VEGF and VEGFR-2 were detected by immunohistochemistry, microvessel density (MVD) were calculated, and the expressions of Survivin and Caspase-3 mRNA were detected by RT-qPCR. Results Compared with model group, protein expressions of VEGF and VEGFR-2, MVD, Caspase-3 and Survivin mRNA decreased in Jianpi Huoxue Prescription high-, medium- and low-dosage groups, and the most obvious differences were in 5-Fu group and Jianpi Huoxue Prescription high-dosage group (P<0.05).
