Objective To observe the changes of mRNA expression related to kidney yang deficiency and the ul-trastructure of hypothalamus in Lewis rats, and further study the constitution of kidney yang deficiency in Lewis rats.Meth-ods Ten 7-8-week old SPF male Lewis rats and twenty 7-8-week old SPF male Wistar rats were used in this study.The rats received subcutaneous injection of hydrocortisone to establish kidney yang deficiency model.The expressions of TNF-α, IFN-γ, IL-10, CRH, MR and GR mRNA in the hypothalamus of the two groups were detected and the ultrastructural changes of hypothalamus and adrenal gland were observed to compare the differences between the two groups, and to ex-plore the mechanism of kidney yang deficiency constitution in the Lewis rats.Results Compared with the normal Wistar rats, the expressions of GR and IL-2 mRNA in the hypothalamus were significantly increased ( P<0.01 ) , while the ex-pressions of CRH, TNF-α, IFN-γand IL-10 mRNA were significantly decreased in the Lewis rats (P<0.01).The zona fasciculata of the adrenal cortex was slightly thinner, the mitochondria were slightly swollen and the amount of mitochondria was decreased.The nuclei of hypothalamic neurons were larger, and the mitochondria, neuron synapses and secretory vesi-cles in the presynaptic neurons were decreased.Conclusions There are abnormal expression of immune-related cytokines and CRH mRNA, and ultrastructural changes in the hypothalamus and adrenal gland of Lewis rats with kidney yang defi-ciency.Such changes may be related to the functional imbalance of the hypothalamus-pituitury-adrenal axis.

Objective To develop the method of 16S rRNA gene clone library for tick bacterial flora analysis, and to analyze the detection effective of pathogens in tick and capacity of bacterial flora diversity. Methods Primers were designed according to the specific gene of Borrelia burgdorferi, Bartonella henselae, Anaplasma phagocytophilum, Ehrlichia chaffeensis and templates were choosen by positive PCR result to amplify the DNA extracted from the ticks. One set of primers targeting 16S rRNA gene conserved region were chosen to amplify certain fragments, DNA extraction, PCR reaction, cloning and sequencing. Nucleotide sequences were compared with GenBank database. Calculated Coverage values of clone library and Shannon-Wiener diversity index. Results Sixteen defined genus-or species-bacteria were detected in 103 valid sequences. Eight species were edge type (Clone No. > 5). Three kinds of pathogens were identified (Borrelia burgdorferi, Bartonella henselae and Rickettsia sp). Three kinds of pathogens were not edge type(Clone No. < 5). Coverage value was 96.11%, and Shannon-Wiener index was 2.40. Analysis results of cloning sequence showed that tick-parasitic bacteria mainly were α and γ deformation mycetes which accounted for 56.25% (9/16). Conclusions The 16S rRNA gene sequences technology could make relative quantitative of bacterial flora, and detect many kinds of pathogens in tick. It's a good method for detection of pathogens and bacterial flora analysis.

OBJECTIVETo establish a mouse model of biliary obstruction.
METHODSSixty-four Balb/c mice were divided into experimental group and control group. Obstructive jaundice was induced in the mice in the experimental group by common bile duct ligation. The level of the common bile duct diameter, WBC, LYM MID, LYM%, MID% and ALT, AST, TBIL, DBIL, IBIL, ALP and CHOL were measured 12 h and 1, 2 ,3, 4, 5, and 7 days after the ligation. The morphological changes in the liver were also observed.
RESULTSThe level of common bile duct diameter, WBC, LYM, MID, LYM%, MID% and ALT, AST, TBIL, DBIL, ALP and CHOL all underwent changes with time following certain patterns.
CONCLUSIONThe jaundice manifestation of this model is similar to that of patients with biliary obstruction, and this model may provide a reliable model for studying the mechanism of obstructive jaundice.

OBJECTIVETo determine the optimal cytokine combinations with hepatic growth factor (HGF) that results in the most significant simultaneous in vitro expansion of cc-kit(+)Lin(-) cells derived from the bone marrow.
METHODSC-kit(+)Lin(-) cells were isolated from mouse bone marrow using a high-gradient magnetic cell sorting system (MACS) and expanded in the presence of stem cell factor (SCF), FLt-3 ligand (FL), leukemia inhibitor factor (LIF) thrombopoietin (TPO) and different concentrations of HGF for 7days in a liquid culture system. The total cell number and Annexin-V-positive cell number were counted, and the antigen expressions were studied with fluorescence-activated cell sorting (FACS).
RESULTSIn each group, c-kit(+)Lin(-) cells were expanded effectively and rapidly by 2 to 8 folds. Addition of 10 ng/ml HGF into SCF+FL+LIF+TPO resulted in the most significant expansion of c-kit(+)Lin(-) and total cells by 8.00 and 45.43 folds, respectively, with cell apoptosis rate of 17.42 %. But as the concentration of HGF increased, the c-kit(+)Lin(-) cells and the apoptosis rate decreased.
CONCLUSIONHGF at10 ng/ml shows optimal synergistic effect with SCF, FL, LIF and TPO in expansion of c-kit(+)Lin(-) cells, and excessive HGF may induce cell differentiation.
