The continuous cultivation of Rehmannia glutinosa causes the accumulation of phenolic acids in soil. It is supposed to be the reason of the so called "continuously cropping obstacle". In this study, phenolic acids (hydroxybenzoic acid, vanillic acid, eugenol, vanillin and ferulic acid) were degraded by the extracta of all the tested spent mushroom substrate (SMS) and the maximal degradation rate was 75.3%, contributed by extraction of SMS of Pleurotus eryngii. Pot experiment indicated that hydroxybenzoic acid and vanillin in soil were also degraded effectively by SMS of P. eryngii. The employment of SMS enhanced ecophysiology index to near the normal levels, such as crown width, leaves number, leaf length, leaf width and height. At the same time, the fresh and dry weight and total catalpol concentration of tuberous root weight of R. glutinosa was increased to 2.70, 3.66, 2.25 times by employment of SMS, respectively. The increase of bacteria, fungi and actinomycetes numbers in rhizosphere soil were observed after the employment of SMS by microbial counts. The employment of SMS also enhanced the enzyme activity in soils, such as sucrase, cellulase, phosphalase, urease and catelase. These results indicated that the employment of SMS alleviated the continuously cropping obstacle of R. glutinosa in some extent.

Objective To assess the feasibility of using PET molecular imaging to evaluate the therapeutic effects of traditional Chinese medicine FuZhiSan (FZS) on the model of aging Alzheimer's disease (AD) rats. Methods Twenty aged AD rats (Sparague-Dawley rats,male) were randomly divided into FZS treated group (n = 10) and control group (n = 10). Another 10 healthy adult rats were as blank controls. Morris water maze record system was used for cognitive function assessment. Before and after FZS treatment 18 F-fluorodeoxyglucose (FDG) and 11 C-2- [4'-(methylamino) phenyl] benzothiazol-6-ol ( PIB )PET imaging was undertaken. After post-treatment imaging procedures the brain tissues of all animals were taken for histochemical study,such as staining with HE,congo red,amyloid β (Aβ) immunofluorescence,5-bromo-2-deoxyuridine (BrdU) immunofluorescence and NeuN immunofluorescence. Paired t-test was performed with SPSS 13.0 software for the data analysis. Results The cognitive dysfunction of aging AD rats was improved after FZS treatment. The escape latency in FZS treated group was significantly shorter than that of control group ((32.5 ±10.8) s vs (102.6±8.8) s,t =15.7987,P=0. 0001). Diffuse neuronal loss and Aβ deposition were detected in the hippocampus and cortex in the aged AD rats. The imaging data showed that brain glucose metabolism was amended in FZS treated group while the abatement of amyloid deposition was not significant. Immunofluorescence results indicated that the neuronal proliferation was more remarkable in FZS treated group. Conclusions It may be feasible to use PET imaging as a method to evaluate the therapeutic effect in AD rats. FZS may ameliorate memory dysfunction of aged AD rats. Its mechanism may be partly contributed to the enhancement of the neuronal proliferation and survival.

Objective To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome among Kazakh and Han ethnicities in Xinjiang.Methods PCR-RFLP was used to detect 802 subjects' lipoprotein lipase Hind Ⅲ and S447Xgenotypes (including 201 controls and 200 metabolic syndrome patients in Kazakh and Han ethnicities, respectively). Results (1) Frequencies of H + H-/H-H- genotype (32.50% vs.47.76%), H- allele( 18.00% vs. 28.86%), SX/XX genotype (8.00% vs. 22.39%) and X allele (4.00%vs. 12.44% ) for metabolic syndrome in Hah ethnicity were all significantly lower than those in controls (P＜ 0.01 ). (2) The frequencies of H + H-/H-H- genotype (33.50% vs. 46.80% ), H- allele (22.00% vs. 28.60%), SX/XX genotype (10.50% vs. 22.90%) and X allele (5.50% vs. 12.44% ) in patients with metabolic syndrome in Kazakh were all significantly lower than those for controls (P＜0.01). (3) The frequencies of lipoprotein lipase gene Hind Ⅲ and S447X genotypes and alleles in Kazakh were not significantly different from Han (all P＞0.05). (4)The levels of waist circumference, systolic blood pressure, diastolic blood pressure, triglyceride and FPG in H + H-/H-H- and SX/XX genotype were significantly lower than those in H + H + and SS genotype.HDL-C was significantly higher than that in H + H + and SS genotype (P＜0.05). (5) The frequencies of H + H + and SS genotype increased along with the increase in number of metabolic syndrome component. Conclusion The lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms were associated with metabolic syndrome risk in Kazakh, and H + H-/H-H- genotype, H- allele, SX/XX genotype and X allele might have served as protective factors of metabolic syndrome. H + H-/H-H- and SX/XX genotype seemed to have had beneficial effects for all the metabolic syndrome components, and the frequencies of H + H + and SS genotype were increasing along with the increase of number in the metabolic syndrome components.

OBJECTIVETo analyze the prevalence and risk factors of metabolic syndrome (MS) in Xinjiang Uygur adults.

METHODSWith cluster random sampling, investigations including questionnaire, physical examination and blood testing were performed among 3442 Uygur adults among in Kashgar of Xinjiang on November 2010. Prevalence of MS in groups with different characteristics were calculated and non-conditional logistic regression analysis were used to analyze the risk factors.

RESULTSThe prevalence of MS was 21.2% (728/3442), and the age-adjusted prevalence was 18.5%. The prevalence among males and females was 14.5% (245/1694) (age-adjusted prevalence 12.7%) and 27.6% (483/1748) (age-adjusted prevalence 24.4%) respectively (P < 0.05). The prevalence of MS among 18 to 24 years old and 65 years old and above were 4.3% (21/490) and 28.9% (109/377) respectively. The prevalence of MS increased with age (χ(2) = 204.13, P < 0.05). The prevalence of low blood HDL-C, central obesity, hypertension, hypertriglyceridemia and hyperglycemia was 57.5% (1978/3442), 44.5% (1531/3442), 27.5% (948/3442), 20.2% (696/3442) and 8.6% (297/3442) respectively. Compared to age group 18 - 24, the risk of MS occurrence was higher in age group 25 - 34, 35 - 44, 45 - 54, 55 - 64 and 65 years-old above, the according OR (95%CI) values were 2.29 (1.38 - 3.81), 6.91 (4.31 - 11.09), 10.81 (6.72 - 17.40), 12.52 (7.74 - 20.26) and 10.20 (6.20 - 16.78), respectively. Smoking also increased the risk of MS (OR = 2.35, 95%CI: 1.64 - 3.37).

CONCLUSIONThe prevalence of MS in Xinjiang Uygur was in high level; The prevalence of MS is higher in female than in male; The risk factors of MS included female, age and smoking.
