Objective To observe the effects of total saponins of tribulus of various consistency on the differentiation of neural hippocampus stem cells. Methods The hippocampus stem cells from newborn rat were obtained by serum-free medium and single-cell cloning technique. Hippocampus stem cells were induced by total saponins of tribulus of various consistency. Nestin, BrdU, neurofilament (NF-200), glial fibrillary acidic protein (GFAP) expression were detected using immunocytochemical stains. The numbers of NF and GFAP positive cells were counted. The percentages of positive cells were obtained. Results The dissociated cells from the organ of hippocampus developed into much of indiffrentiated otopheres of nestin positive cells. The hippocampus stem cell differentiated into neurons and astrocytes with the total saponins of tribulus. The percentage of NF positive neuron in the 20 mg/kg consistency of total saponins of tribulus groups was significantly higher than that in the control group and other consistency of total saponins of tribulus groups. Conclusion Total saponins of tribulus may enhance neural hippocampus stem cells differentiate into NF positive neuron.

Objective To explore the application of three dimensionally structured nursing management mode in the treatment of multiple trauma patients. Methods One hundred and eighty-seven patients with multiple injuries in the emergency department of our hospital from January to December 2010 were set up as the control group, and the traditional method was used in the group. Another 189 patients with multiple injuries from January to December 2011 were set as the observation group , in which the three dimensionally structured nursing management mode was used. The two groups were compared in terms of success rate. Result The success rates of the observation group and the control group were 85.7%(162/189) and 71.7%(134/187), respectively. The difference between the two group was statistically significant (Χ2=19.19,P<0.01). Conclusion The implementation of the three-dimensionally structured nursing management model can improve the comprehensive ability of emergency treatment and then improve the success rate of rescuing emergency patients.

Objective To investigate the relationship between the C-reactive protein (CRP) and nonalcoholic fatty liver disease (NAFLD) prevalence.Methods In this study,63,486 workers who had participated in the Kailuan health examination from July 2012 to October 2013 and without history of drinking,myocardial infarction,stroke and cancer and without data incomplete were recruited.The observation population was divided into three groups according to the levels of CRP at baseline:group 1 (＜ 1 mg/L),group 2 (1-3 mg/ L) and group 3 (＞3 mg/L).The prevalence of NAFLD among three groups was observed.Multiple logistic regression was used to calculated relationship between the CRP and NAFLD prevalence.Results The prevalence of NAFLD in group 1,group 2 and group 3 were 26.9％,42.1％ and 49.3％,respectively,and the differences were significant (x2=2 192.31,P ＜ 0.01).Logistic model showed that after adjustment for age,gender,waist circumference and other confounders,the association between CRP and NAFLD was strong and the OR value (95％ CI) among the group 1,group 2 and group 3 were 1.00,1.49 (1.42-1.56),1.54 (1.45 -1.64),respectively.Conclusion CRP is independently associated with the nonalcoholic fatty liver disease.

Objective To investigate the correlation between toll-like receptor 9 (TLR9) gene 2848G/A polymorphism and primary antineutrophil cytoplasmic antibodies (ANCA) associated small vasculitis (AAV). Methods A case-control study was performed among 135 patients diagnosed with AAV and 140 disease-free control and we test the serum biochemical parameter. Polymorphism was analyzed by polymerase chain restricted fragments length polymorphism. As for statistic method, according to the character of data, we performed t-test, chi-square test, Spearman grade related analysis and one-way ANOVA. Results ① The frequencies of AA, GG, GA genotype of TLR9 2848 in AAV patients were 14.07%, 38.52%, and 47.71%, respectively; ② Significant increase in IgM was observed in AA genotype than GG+GA genotype in AAV patients (F=4.561, P<0.05). ③ There was no significant difference between AI and CI in AA, GA and GG genotype in AAV patients (F=2.115, 0.760, P>0.05). Conclusion AA, GA and GG genotypes are detected in TLR9 2848G/A in patients with AAV in Guangxi, without significant correlation with susceptibility to primary AAV in Guangxi.

Objective To investigate the correlation between Toll-like receptor2 (TLR2) gene promoter region -597T/C polymorphism and primary ANCA associated small vasculitis (AAV) in Guangxi Han people. Methods A case contrastive control study was adopted in the study. Patients with AAV (patients group, n=110) and healthy people (control group, n = 200) were recruited. Associated serum indexes were detected and polymorphisms of TLR2 gene promoter 597T/C were analyzed by polymerase chain restricted fragment length polymorphisms (PCR-RFLP). Results (1)Three TLR2-597T/C genotypes were discovered in 110 AAV patients, namely, TT, TC and CC, with the frequency of 54.55%,40.00% and 5.45% respectively. And the frequencies of allele T and C were 74.55% and 25.45%. In control group, the genotype frequencies of TT, TC and CC were 56.00%,40.50% and 3.50%, with 76.25% of allele T and 23.75% of allele C. No significant differences were found in neither genotype distribution nor allele frequencies between the patients group and control group ( P > 0 . 05 ) . ( 2 ) Significant differences were found in the incidence of proteinuria rate and the hemoglobin (P< 0.05)in AAV patients. (3)There was no significant difference between AI and CI in TT, TC and CC genotype in AAV patients. Conclusions Polymorphism of TLR2-597T/C may be correlated with the incidence of proteinuria and the level of hemoglobin, while no obvious correlation with the genetic susceptibility of ANCA in vasculitis patients of Guangxi Han people.
