ABSTRACT
OBJECTIVES@#Due to the genetic feature of high diversity than other DNA markers, short tandem repeat (STR) plays key roles in forensic, anthropology, and population genetics. Newly introduced multiple STR kit is more valuable because of the greatly improved discriminatory power with the increase in the number of STR loci. The genetic polymorphic data are essential for the application and research in specific population. This study aims to investigate the genetic polymorphism of Han population residing in Yuncheng district, Shanxi Province, to evaluate the application of 23 STR loci in forensic personal identification and paternity test, and to explore the genetic relationship of Han population between Yuncheng and other populations.@*METHODS@#A total of 23 STR loci were amplified from 525 healthy unrelated individuals from the Han nationality in Yuncheng, Shanxi Province using the AGCU EX25 amplification kit. The products were detected and separated by ABI 3500 Genetic Analyzer. Alleles were genotyped by GeneMapper ID (Version 3.2) software, and corresponding frequencies and forensic parameters were calculated. We calculated the genetic distance and plotted the neighboring-joining tree with other 13 population.@*RESULTS@#The allele frequency of the 23 STRs ranged from 0.0010 to 0.5090. No deviation from Hardy-Weinberg equilibrium (@*CONCLUSIONS@#These 23 STRs are highly genetic polymorphic and informative in the Han population of Yuncheng, Shanxi Province, which can provide basic data for forensic personal identification, paternity testing, and population genetic research.

OBJECTIVE:To study the improvement effects of Rouganbao granules on liver fibrosis of model rats,and to provide experimental evidence for further development of this preparation. METHODS:Totally 45 male SD rats were divided into normal group,model group,positive control group(Fuzheng huayu capsules,0.4 g/kg)and Rouganbao granules high-dose and low-dose groups(16.8,8.4 g/kg by crude drug)according to random number table,with 9 rats in each group. Except for normal group,other groups were given CCl4sub cutaneously and high lipid diet+15% ethanol solution for 12 weeks to establish liver fibrosis model. After modeling,medication groups were given relevant medicine intragastrically,once a day,for consecutive 12 weeks. Normal group and model group were given corresponding volume of water intragastrically. The pathology change of liver tissues of rats was observed by inverted microscope. The levels of liver function indexes (ALT,AST,ALB) and liver fibrosis indexes(HA,Ⅳ-C,LN,Ⅲ-PC)were determined by ELISA. RESULTS:Compared with model group,liver cell vacuolation and liver fibrosis of rats were improved significantly in Rouganbao granule high-dose and low-dose groups;central vein was clearly visible,and no dilation and atrophy were found,especially in high-dose group;the serum levels of ALT and AST were decreased significantly,while the level of ALB was increased significantly(P＜0.05 or P＜0.01),of which the protective effect for liver was similar to positive control drug but better in increasing ALB(P＜0.05 or P＜0.01);the serum levels of HA,Ⅳ-C,LN and Ⅲ-PC were all decreased in varying degree,especially in high-dose group(P＜0.05 or P＜0.01),of which the effect of relieving liver fibrosis was similar to positive control drug. CONCLUSIONS:Rouganbao granules can improve liver function and delay the progression of liver fibrosis in model rats.

ABSTRACT
Objective:To explore the expression of IL-22 in the patients with rheumatoid arthritis,and to define the clinical sig-nificance of IL-22 cells for RA. Methods: A total of 50 RA patients, 15 OA patients and 15 healthy controls were enrolled. The proportion of Th22 cells in peripheral blood and synovial fluid( SF) of RA patients was detected by flow cytometry;the levels of IL-22 in serum and synovial fluid of RA patients were detected by ELISA. The clinical parameters of disease activity were assessed including ESR,RF,CRP,DAS28,anti CCP and the degree of bone erosions determined by X-rays. Pearson correlation analysis,t test and Kruskal-Wallis H test were used for statistical analysis. Results:The proportion of Th22 cells in RA patients was higher than that of OA patients (t=2. 290 ,P=0. 021) and healthy controls(t=2. 524,P=0. 015). IL-22 levels in RA patients were higher than that of OA patients (t=2. 560,P=0. 014) and healthy controls(t=2. 768,P=0. 009). IL-22 in the RF positive group were higher than that of RF negative group(t=2. 322,P=0. 035). IL-22 in the anti-CCP antibody positive group were higher than that of anti-CCP antibody negative group (t=2. 504,P=0. 015). The levels of IL-22 were correlated positively with ESR,RF,DAS28(r=0. 312,0. 314,0. 332,P χ20.05(3),P<0. 05). Serum IL-22 levels in the RA patients with joint effusion were higher than that of without(t=2. 587,P=0. 012). The levels of IL-22 in SF were higher than that in serum(t=2. 668,P=0. 011),and had no correlation with the proportion of Th22 cells in SF. Conclusion: The expression of IL-22 in serum and joint effusion of RA patients increase. The level of IL-22 may be useful marker for assessment of disease activity and finding of bone erosions. Therapeutic targeting of IL-22 may be valuable for the intervention of RA.

ABSTRACT
NHL proteins, which play important roles in regulation of cell proliferation and differentiation, have been extensively studied on mammals. Here, we cloned a member of NHL protein family namely BmBrat in silkworm. The full-length cDNA sequence of BmB rat was obtained by means of the rapid amplification of cDNA ends (RACE), including 3 614 bp. The ORF is 2 580 bp long, encoding a protein with 859 amino acid residues. The molecular weight is 94.3 kDa and the isoeledtric point (pI) is 6.65. The BmBrat expression profile was detected by RT-PCR at L5D3 larval stage, and it was expressed in all tissues, including silk gland, midgut, fat body and malpighian tubule. However, it was highly expressed in ovary and head. The expression profile was also detected at different stage of embryo development, and reached a peak at the 4th and 5th days of the embryonic period. Anti-BmBrat polyclonal antibody was generated f6llowing prokaryotic expression, protein purification and mice immunization, which is highly specific and effective for recognizing BmBrat protein through Western blotting and immunofluorescence staining. Subcellular localization of BmBrat in hemocytes revealed that it was specifically expressed in cytoplasm. This study provides a foundation for further research of the biological function of BmBrat gene.

ABSTRACT
Cyclic voltammetry shows that, in a supporting ele ctrolyte of NaOH,riboflavine tetrabutyrate（RT）has a pair of cathodic and anodi c peaks at Hg electrode. The peak potentials Epc=Epa=-0.64 V（vs.Ag/Agcl）. The adsorptive characteristics of RT are explored in detai ls with various methods. The adsorbed species is most probably neutral molecule of RT.The saturated adsorption amount of RT at Hg electrode is 5.42×10-11 mol/cm2 and every RT molecule occupied 3.06 nm2. On the surface of HMDE ，the adsorption of RT obeys Frumkin dasorption isotherm. The adsorptive coeffic ient β，the attractive factor γ are 4.60×105，1.10 and the adsorption free energy ΔG, is －32.30 kJ/mol, respectively. The electrode proc ess kinetic behavior has also been studied by using cyclic voltammetry. Under th e experimental conditions the rate constants for electron transfer are determine d. The values of ks are in good agreement with literature′s results.
