OBJECTIVE:To investigate the correlation of total saponins and total polysaccharides content in the roots of Pari-dis rhizoma genus plants with Arbuscular mycorrhizal fungi(AMF)infection rate and rhizosphere soil nutrients. METHODS:Tak-ing 16 pieces of Paridis rhizoma herbs and rhizosphere soil in Three Gorges Reservoir Area as the research object,mycorrhizal in-fection rate and infection intensity,the contents of total saponins and total polysaccharides in roots and stem,and rhizosphere soil nutrient contents were all determined. SPSS18.0 software was adopted for data multiple comparison and correlation analysis. RE-SULTS:Paridis rhizoma genus plants roots in Three Gorges Reservoir Area could form a good symbiotic relationship with AMF. In-fection rate ranged from 85.19% to 99.80%,and infection intensity ranged from 16.55% to 72.27%. Paridis rhizoma from differ-ent origins and varieties had significant difference in the contents of total saponins and total polysaccharides (P<0.05). Soil pH was moderate,the average content of total nitrogen was in insufficient level,the average concentration of the remaining nutrients belonged to middle levels or above. Correlation analysis showed that the mycorrhizal infection rate and infection intensity of Paridis rhizoma were not significantly correlated with its quality. The total saponins were significantly negatively correlated with organic matter and available nitrogen. The total saponins and total polysaccharides were positively correlated with available phosphorus,po-tassium and pH value,but they were not significantly correlated with the other soil nutrients. CONCLUSIONS:Paridis rhizoma is selective to different soil nutrients. Rich soil available phosphorus and potassium supply are in favor of the synthesis and accumula-tion of total saponins and total polysaccharides in Paridis rhizoma roots.

Results The production was identified as gloverin peptide by Western blotting, and the TAL data indicated that the production could neutralize LPS. Conclusion Anti-bacterial peptide gloverin is successfully expressed in E.coli BL21.

Objective To explore the potential risk factors for aortic and mitral valve calcification in maintenance hemodialysis(MHD)patients. Methods Patients on MHD for at least 6 months.aged≥1 8 years without history of surgery or catheter for heart valve disease were enrolled in the study.Echocardiographic examination was performed to detect the calcification.The risk factors for aortic and mitral valve calcification were analyzed by Logistic regression. Results One hundred and eighty-one MHD patients(98 men and 83 women)were enrolled in the study.Of all the patients,aortic or mitral valve calcification was found in 94 patients(5 1.9%),aortic valve calcification in 90 patients(49.7%),mitral valve calcification in 30 patients(16.6%),aortic and valve calcification in 26 patients(14.4%).Multivariate Logistic regression showed that age(β=5.52,P=0.007),dialysis duration(β=6.99,P=0.039)and pre-albumin(β=-12.616,P=0.004)were independently correlated with aortic valve calcification.Mitral valve calcification was independently correlated with dialysis duration(β=6.057,P=0.002),history of primary hypertension(β=3.054,P=0.008),hemoglobin(β=-0.061,P=0.035)and β2 microglobulin(β=7.63,P=0.01).While the correlation between mitral valve calcification and age was borderline significant(β=0.085,P=0.05).Conclusions Valve calcification is prevalent in MHD patients,and aortic valve calcification is more common than mitral valve calcification.Age,dialysis duration and low serum pre-albumin are independent risk factors for aortic valve calcification.The risk factors for mitral valve calcification include age,dialysis duration,history of primary hypertension,anemia and high serum β2 microglobulin.

Objective To identify the efficacy and safety of aspirin in reducing the serum high sensitivity C reactive protein(hsCRP)level and preventing the internal arteriovenous fistulas(AVF)embolism in maintenance hemodialysis patients. Methods One hundred and ten hemodialysis patients using AVF more than 3 months were randomly divided into 2 groups,the intervention group(n=55,received aspirin 100 mg/d)and the control group(n=55).Examinations were performed at baseline and 6-month after treatment.Serum hsCRP level,platelet aggregates ratio(PAR),coagulation and inflammation indicators were measured.AVF embolism and the adverse events were monitored. Results Six months later.PAR and hsCRP level of the intervention group patients aged≤60 years decreased significantly [(68.14±8.45)%vs (82.37±9.12)%;(4.79±4.81)mg/L vs(6.94±10.26)mg/L,all P＜0.05],and were significantly lower as compared to.the control group[(68.14±8.45)%vs(74.7±11.50)%,(4.79±4.81)mg/L vs(5.12±9.25)mg/L,all P＜0.05].There were 2 cases of AVF embolism occured in both groups,which showed no statistical difierence (P=0.676).The incidence of adverse effeets was higher in the intervention group than that in the control group but no statistical significance was found (20.0%vs 7.2%,P=0.052),while the mortality rate had no difference between 2 groups (3.6%vs 0,P=0.495).Conclusion Use of aspirin 100 mg/d for 6 months can significantly reduce the serum hsCRP level and PAR in hemodialysis patients under 60-year-old without serious adverse reactions.

Objective Linkage analysis were performed in 2 pure Chinese paroxysmal kinesigenic dyskinesia families to localize the locus of them. Method Microsatellites markers corresponding to pericentrometric region of chromosome 16 were used in parametric and nonparametrie linkage analysis for 27 members in the 2 pedigrees, haplotypes were constructed subsequently. Result The maximum LOD score and NPL score in the 2 families were all negative, P values were significantly larger than 0.05.No haplotype segregated with PKD phenotype was found. It showed no evidence of association with known PKD loci in both pedigrees, providing evidence for a novel PKD locus. Conclusion PKD is heterogeneous, a novel PKD locus may be in pure Chinese pedigrees.

Objective To examine the effect of fibronectin connecting segment-1 (CS1) peptidefacilitated blockade of inflammatory cells-fibronectin adhesion on a rat liver transplantation model of prolonged ex vivo cold ischemia.Methods A model of liver transplantation in Wistar→Wistar rat was established.The donors of the CS1 treatment group received CS1 peptides through the tail vein for 3 days before operation.Another two doses of CS1 peptides were administered into the liver intraportally during procurement and before transplantion.Recipients received an additional 3-day course of CS1 peptides after transplantation.Rats in control group received scrambled peptides.Rats were sacrificed at 6,24 and 72 h after transplantion,and plasma transaminase activity and hepatic pathological changes were studied.The inflammatory cells and liver sinusoidal endothelial cells were visualized histochemically.Real-time PCR was used to detect tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β) and vascular endothelial growth factor (VEGF) mRNA expression in the liver.Results The plasma transaminase activity and hepatic necrosis areas in CS1 treatment group were significantly lower than in control group (P＜0.05).CS1 peptides treatment significantly decreased the number of Kupffer cells after transplantation and greatly inhibited the recruitment of neutrophils to the graft liver as compared with control group (P＜0.05).After prolonged cold ischemia,only a few hepatic endothelial cells exhibited positive staining of hepatic sinusoidal endothelial cell biomarker SE-1.Lots of hepatic sinusoidal endothelial cells positive for SE-1 staining could be detected in CS1 group at 72 h after transplantation,while much less SE-1 positive cells presented in the control goup.Prolonged cold ischemia caused a significant increase of TNF-α,IL-1β and VEGF mRNA expression in the graft liver of control group after transplantation.The expression of TNF-α mRNA at 6 and 24 h and VEGF mRNA expression at 24 h were significantly lower in CS1 group than in control group (P＜0.05).Conclusion Peptide-mediated blockade of inflammatory cells-fibronectin interaction decreased the mRNA expression of inflammatory cytokines,prevented hepatic sinusoidal endothelial cells from injury and subsequently protected against severe ischemia/reperfusion injury of the graft liver after transplantation.

Objective To study the amount of rhizospheric microorganisms and soil enzyme activity influenced by Paridis Rhizoma in different locations and of different strains. Methods The amount of rhizospheric microorganisms, soil enzyme activity and their correlation were researched through field survey and collection of rhizospheric soil in Paridis Rhizoma cultivated in Three Gorges Reservoir Region and by microbial dilution plate culture method. Results The amount of rhizospheric microorganisms in Paridis Rhizoma from different habitats showed significant differences. The dominant species in soil microflora was bacteria; the second one was actinomycetes; the fewest one was fungus. The variation trend of the amount of rhizospheric microorganisms was not consistent with the variation trend of rhizospheric microorganisms diversity index. The activity of soil phosphatase, invertase and pepsin in Paridis Rhizoma from different habitats varied. The correlation analysis showed that the correlation between the soil enzyme activity and the amount of rhizospheric microorganisms existed. Conclusion Choosing the suitable strains and habitats of Paridis Rhizoma is beneficial to enhancing the amount of rhizospheric microorganisms and soil enzyme activity, which can create good micro-ecological environment for growth and cultivation of Paridis Rhizoma.
