Objective To explore the spatial distribution of Keshan disease(KD) in the 15 surveillance provinces(municipalities,autonomous regions ) and to provide the basis for the development of prevention and control strategies.MethodsBased on the KD surveillance data of the 15 provinces in 2007,five indicators were selected.Moreover,a comprehensive indicator score to assess KD of different areas was made through the method of principle components analysis,which was applied for regionalization of the KD areas by the subsection method of standard deviation in whole China.The KD areas were divided into mild,moderate and severe endemic areas.The spatial distribution feature of the comprehensive indicator score was displayed by using geographic information system (GIS).ResultsThe three principal components contained 88.123％ information of all the selected indicators,the first principal component had a close relationship with total KD detection rate,chronic KD detection rate and latent KD detection rate; the second principal component had a close relationship with the threatened number in KD areas,and the third principal component had a close relationship with new KD detection rate; the comprehensive indicator indicates that Gansu,Jilin,Heilongjiang,Hebei,and Liaoning provinces were serious prevalent KD areas; Inner Mongolia,Shandong,Hubei,Sichuang provinces (autonomous region) were moderate prevalent KD areas,and Shanxi,Shaanxi,Yunnan,Henan,Guizhou,Chongqing provinces(municipality)were mild prevalent KD areas.Conclusions The introduction of the GIS to Keshan disease monitoring,provides a convenient and direct method to observe the spatial distribution of the disease,and the results point out the key areas for further KD surveillance according to local conditions.

ObjectiveTo evaluate whether the junior high school students reared by their grandparents in 0～3 years old have more emotional and behavioral problems than their counterparts who reared by birth parents since birth. MethodsThis study was carried out to compare emotional and behavioral outcomes,using Youth Self-Report(YSR) between junior high school students reared by their grandparents in 0～3 years old and junior high school students reared by birth parents since their birth. ResultsTwo-sample test showed that the study group had significantly higher raw scores of the YSR sub-scale of somatic complaint[(2.93±2.83) vs (2.00±2.35),t=2.08,P＜0.05],social problems[(3.56±2.20) vs (2.42±1.99),t=3.15,P＜0.01],thought problems[(3.29±3.26) vs (2.16±2.29),t=2.30,P＜0.05],delinquency [(2.77±2.33) vs 2.01±1.60),t=2.19,P＜0.05] ,aggression[(7.89±6.32) vs 5.96±4.66),t=2.01,P＜0.05],externalizing problems [(10.67±8.07) vs (7.97±5.61),t=2.19,P＜0.05]and total problems [(42.64±22.76) vs (33.61±19.25),t=2.47,P＜0.05]than the comparison group. Analysis of covariance (ANCOVA) was used to control the effects of live events stress. The following analyses showed that the two groups showed no significant difference except for social problems (P＜0.05). ConclusionMany factors that affect mental health of the junior high school students. There is a significant differences in the social problems between the junior high school students reared by grandparents from infancy to the toddler stage and their counterparts. The grandparents should pay more attention to help their grandchildren developing social skills in their babyhood.

Objective To discuss the effects and mechanisms of tetramethylpyrazine(TMP)on learning and memory abilities of Alzheimer's disease(AD)mice.Methods The animal models of AD were induced by aluminium trichloride(AlCl3)intragasticly for forty days.Then,TMP was intragastricly administered for twenty days.The escape latency of the mice in water maze test was recorded;and AChE and SOD activities and MDA levels in the brain were detected by chemical eoiorimetrie method.The expressions of At3 and NF-κB in the cerebral cortex were measured by immunohistochemistry method.Results 1)TMP has markedly decreased escape latency in AlCl3 induced AD mice(P＜0.05).2)In the brain of AlCl3 induced AD mice,TMP reduced AChE activity 19%[(1.37±0.13)U·mgpro-1vs(1.69±0.27)U·mgprot-1,P=0.016],decreased MDA levels 34% [(43.63 4-13.27)nmol·mgprot-1 vs(28.59±8.52)nmol·mgprot-1,P=0.023]and increased SODD activity 39%[(55.81±10.25)U·mgprot-1 vs(40.04±13.06)U·mgprot-1,P=0.026],respectively.These resuits showed significant difference with model mice group(P＜0.05).3)TMP also decreased AB and NF-κB expressions in the cerebral cortex of AD mice models(P＜0.05).Conclusion In AlCl3 induced AD mice,TMP can remarkably enhance the learning and memory abilities,presumably in relation to raise the activity of SOD,reduce the activity of AChE,the levels of MDA and the expressions of AB and NF-κB in the brain.

Objective To establish a method for quantitative detection of hepatitis B virus covalently closed circular DNA(HBV cccDNA ) in infected cells. Methods The transfected cell line HepG2.2.15 which can consistently produce Dane particles was maintained in DMEM containing 380 ?g/ml G418 and 10% fetal bovine serum. Cells in the exponential period were harvested from flasks, then intracellular HBV cccDNA was extracted from pellet containing 1?10~6 cells with mini plasmid extraction kit (QIAGEN).The extraction product was further purified by mung bean nuclease to remove HBV relaxed circular DNA possibly remained. HBV cccDNA was quantitatively detected by fluorescent PCR with selective primer set and Taqman MGB probe. Culture medium before exponential period, HBV DNA positive and negative serum samples from patients with chronic hepatitis B (mild) were amplified simultaneously to test the specificity of the fluorescent PCR method. Plasmids containing whole HBV genome were amplified with the same primer set and fluorescent probe to determine the sensitivity of the method. Results HBV cccDNA was detectable in HepG2.2.15, and the average quantity was 18 copies per cell approximately. No detectable fluorescent signal was observed when culture and serum samples were amplified. The detectable HBV cccDNA was as low as 10~3 copies per ml at least by this method. Conclusions This method is convenient, highly specific and highly sensitive. It can be utilized in the quantitative detection of intracellular HBV cccDNA as well as in the screening and evaluation of antiviral agents.
