Objective To explore lymphocyte differentially expressed protein profile and its pathogenic significance in Huaihua Dong peoples with hypertension.Methods The lymphocyte protein profiles among 130 cases of blood specimen were detected and identified with matrix-assisted laser desorption ionization/time of flight mass spectrometry (MALDI-TOF-MS) and Mascot search against protein database.Results The reproducible protein-maps of two-dimensional gel electrophoresis were obtained among three groups.Compared with Dong normal peoples,the protein disulfide isomerase-related protein 5 and heat shock protein 27 showed higher expressions in the Dong peoples with hypertension (P ＜ 0.01),but chain A,structure of haemoglobin in the deoxy quaternary state with ligand bound at the alpha haems is no statistical significance(P ＞0.05).Those three proteins were upregulated in Han peoples with hypertension (P ＜0.01).Conclusions The up-regulation of the protein disulfide isomerase-related protein 5 and heat shock protein 27 in the Dong and Han peoples with hypertension suggest that those two proteins might be associated with the occurrence and development of hypertension.

Objective In order to explore the roles of TLR2 and TLR4 in the hepatocyte dam- age caused hy hepatitis B virus infection,and to find whether LPS can affect the damage of hepato- cytes pre-and pos-HBV infection,we detected the changes of TLR2 and TLR4 expressions in hu- man hepatocyte lines HepG2 cells and 2.2.15 cells.Methods HepG2 ceils are most similar to normal human hepatocytes and 2.2.15 ceils are HepG2 cells infected with HBV.We selected these two cell lines to study the differences of TLR2 and TLR4 expression between HepG2 cells before and after HBV infection.In this research,both HepG2 and 2.2.15 cells were stimulated with 0?g/ml, 1?g/ml,10?g/ml,100?g/ml,1 mg/ml and 10 mg/ml LPS.Then the expression of protein of TLR2 and TLR4 were examined by immuno-histochemistry(IHC).The cnRNA of HepG2 and 2.2.15 ceils stimulated with 0?g/ml and 10 mg/ml LPS were examined by reversal transcription-pol- ymerase chain reaction(RT-PCR).Thereafter,the apoptosis of HepG2 and HepG2.2.15 cells were examined by flow cytometry(FC),and the expressions of HBsAg and HBeAg of HepG2.2.15 cells tested with Abbott kits.Results IHC and RT-PCR analysis revealed that TLR2 and TLR4 expres- sions could he detected in both HepG2 and 2.2.15 cells.Moreover,without immune activation, TLR2 and TLR4 expressions were higher in the presence of higher concentrations of LPS.FC analy sis revealed that no apoptosis detected in HepG2 ceils stimulated with LPS in this research,but apop- tosis could be detected in 2.2.15 cells when treated with the same factors.Furthermore,the apoptosis ratios increased with the increase of LPS concentrations.When concentrations of LPS were 1?g/ml, 10?g/ml,100?g/ml,1 mg/ml and 10 mg/ml,the apoptosis ratios were 1.94%,3.03%,3.50%, 3.72%,5.30%,respectively.Abbott analysis revealed that expressions of HBsAg and HBeAg of 2.2.15 cells stimulated with LPS were lower than those not stimulated with LPS.Conclusion HBV can affect the expressions of TLR2 and TLR4 in HepG2 cell lines.LPS can lead 2.2.15 cells to apop- tosis but not HepG2 cells.Although LPS cannot damage normal hepatocytes,it might aggravate hep- atocytes damage when their microenvironment was changed by HBV infection.

Objective To provide experimental evidences for developing a safe and effective re- combinant fowlpox virus which can prevent the infection of HIV-2.Methods A fowlpox virus(FPV) transferring vector was constructed by inserting HIV-2 gag gene to the downstream of a synthetic complex promoter ATI-p7.5?20 of vector pUTA2.Transfection was then carried out,and recombi- nant FPV(rFPV)was screened by 5'-bromo-deoxyuridine(BrdU),genome PCR and western blot detection.Balb/c mice were immunized with rFPV by muscular injection.Anti-HIV-2 antibody, CD4~+ and CD8~+ T-cell count and specific target-killing activity of spleen CTL in immunized mice were analyzed by ELISA,FACS and LDH release assay,respectively.Results A transferring vector pA- gag was constructed and confirmed by amplifying a fragment of 766 bp from the rFPV genome.Mean- while,HIV-2 multi-antibody-specific protein blot(55 000)was detected from the recombinant virus and the HIV-2 specific antibody was detected from the immunized Balb/c mice.HIV-2 specific target- killing activity of spleen CTL was observed in immunized mice.Conclusion A recombinant fowlpox virus expressing HIV-2 structural protein Gag has been obtained,and it can stimulate HIV-2-specific eelluar and humoral immune reactions in mice.

Objective To evaluate the effects of Radix Astr agali combined with prednisone and i mmunosuppressant for primary nephrotic syndrome (PNS)in adults and to compare the effects o f Radix Astragali in various prepata tions for PNS.Methods Randomized controlled trials were a pplied for systemic reviews.Electr onic and manual retrieve of Medline,Embase,Cochrane Library,CBMdisc a nd CEBM/CCD and relevant medical jou rnals in China were applied to search the RCTs of Radix Astragali,non -specific treatment,glucocorticoids and i mmunosuppresants for PNS,and the RCTs were analysed with RevMan 4.1.Results There were 14randomized controlled trials with 524cases involved.Meta-analysis showed that Radix Astragali could in crease the therapeutic effect of pre dnisone and immunosuppressant for PNS and re-duce its recurrence.Radix Astragali also had an effect in decreasing 24-hour proteinuria content and the pla sma levels of total cholesterol and albumin.There were no differences between single injection and compound decoction.Asymmetry showed in"Funnel plot"may be related to publication bias,l ow quality of methodology and small -size in sample.Conclusion Radix Astragali and its prescriptio n may become a prospect therapy for PN S and its recurrence and the com-bination of traditional Chinese med icine and western medicine can be more effective for PNS.The dedinite effect of Radix Astragali for PNS will be further con firmed by multiple -center,large -s ample randomized controlled trial.

Objective To investigate the influence of glycine supplement on partial biochemical indicator in exhaustive exer‐cise mice .Methods Divided Kunming′s male‐mice into 3 group(10/group):exhaustive swimming group(E) ,exhaustive swimming group with glycine supplement(G) and silent control group (S) .Mice in the G group was treated with 4‐weeked intragastric admin‐istration of glycine ,while mice in other 2 groups received physiological saline .After 4 weeks ,mice in E and G group did the exhaus‐tive swimming exercise .After sampling ,the activity of complement hemolytic activity was measured ,and the serum levels of some biochemical indexes were determined .Results Time of exhaustive swimming in G group was significantly longer than E group(P<0 .01) .After exhaustive swimming ,the ALT ,AST ,ALP ,LDH ,CK ,N ,Fe3+ and CHA in E group were significantly changed com‐pared with S group(P<0 .01);while those indicators in G group were significantly improved than E group (P<0 .01) ,the ALP and LDH level can regain to the level of S group (P>0 .05) .Conclusion Exhaustive swimming mice can have part indicator abnormali‐ty ,but Glycine supplement can effectively improve that condition and enhance the exercise ability to some extent .
