OBJECTIVETo evaluate the influence of Fuzhenghuayu decoction on fibrotic liver tissue and activated hepatic stellate cells (HSCs) using a carbon tetrachloride (CCl4)-induced liver cirrhosis rat model system.

METHODSSixty-four Sprague-Dawley rats were randomly divided into the following groups: normal (non-model, non-drug intervention), CCl4 liver fibrosis model, and CCl4 liver fibrosis model Fuzhenghuayu drug intervention at low dose (0.75 g/kg/d) and high dose (1.5 g/kg/d). The drug intervention was administered via oral-gastric irrigation once daily for 6 times per week over a 6-week period. Four rats from each group were sacrificed at the end of week 2, 4, and 6 for serum and liver tissue collection. Liver fibrosis was evaluated by histology, and expression of a-smooth muscle actin (a-SMA) was determined by immunohistochemistry. Liver function was assessed by measuring levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBil). Between-group comparisons were made by completely random design and ANOVA with Bonferroni correction.

RESULTSAt the end of weeks 2, 4 and 6, all four groups showed significantly different levels of ALT, AST, and TBil; in addition, the model group and drug intervention groups had significantly higher levels of ALT, AST, and TBil than the control group, the drug intervention groups showed significantly lower levels of ALT, AST, and TBil than the model group (P less than 0.01 or less than 0.05), and the differences between the low dose and high dose groups reached statistical significance (P less than 0.01 or less than 0.05). At the end of weeks 2, 4 and 6, the model group and drug intervention groups had significantly higher area ratio of liver fibrosis than the normal group (F = model: 18.68, low dose: 49.95, high dose: 82.44, P less than 0.01), but the two drug intervention groups had significantly less area ratio of liver fibrosis than the model group (P less than 0.05) and the high dose group showed the most robust decrease. In addition, the model group and drug intervention groups showed higher expression of a-SMA than the normal group (F = model: 18.68, low dose: 49.95, high dose: 82.44, P less than 0.01), but two drug intervention groups had significantly less a-SMA than the model group (F = model: 46.32, low dose: 40.30, high dose: 58.42, P less than 0.05) and the high dose group showed the most robust decrease.

CONCLUSIONThe Fuzhenghuayu decoction reduces the numbers of activated HSCs, thereby leading to down-regulated a-SMA expression and reduced degree of liver fibrosis; these effects may represent the mechanism by which this drug suppresses hepatic fibrosis.

OBJECTIVEThe expanded programme on immunization (EPI) is an important part of the social commonwealth projects providing health care service by the government, which benefits communities. Government has the responsibility for EPI's financing which should be covered by the national budget. It is essential that the cost of EPI service be scientifically estimated to provide propriety information for policy makers.

METHODSThis study, using the cost accounting theory of health economics, to calculate EPI service cost at different levels. 3 provinces, 3 prefectures, 9 counties, 18 towns and 12 villages were selected from three provinces Guizhou, Heilongjiang and Zhejiang from the western, central and eastern regions of the country.

RESULTSThe average costs for one EPI-targeted child in Guizhou, Heilongjiang and Zhejiang, were 15.68 Yuan, 29.00 Yuan and 31.09 Yuan, and the costs for one dose were 10.99 Yuan, 18.64 Yuan and 16.51 Yuan, respectively. The costs for complete immunization program for one child were 131.88 Yuan, 242.32 Yuan and 280.67 Yuan, respectively. The main factors affecting the cost would include the average personnel cost (salary and benefit cost) by different economic levels of areas, the number of EPI items developed, and the number of total doses for one child.

CONCLUSION(1) Obvious differences were found between different areas. (2) The proportion of the cost was not reasonably set because of the shortage of input. (3) Guideline for different areas to compensate the working item cost according to the number of the items should be formulated.

OBJECTIVE: To analyze gene expression profile of T cell lymphoma Jurkat cell line treated with paclitaxel by computational biology based on next generation sequencing and to explore the possible molecular mechanism of paclitaxel resistance to T cell lymphoma at gene level. METHODS: IC50 of paclitaxel on Jurkat cell line was determined by CCK-8 assay. Gene expression profile of Jurkat cells treated with paclitaxel was acquired by next generation sequencing technology. Gene microarray data related to human T cell lymphoma were screened from Gene Expression Omnibus (GEO) database (including 720 cases of T cell lymphoma and 153 cases of normal tissues). Combined with the sequencing data, differential expression genes (DEGs) were intersected and screened. DAVID database was used for enrichment analysis of GO function and KEGG pathway to determine and visualize functional entries of DEGs, and protein-protein interactions network of DEGs was drawn. The levels of gene expression were detected and verified by RT-qPCR. RESULTS: CCK-8 results showed that the proliferation of Jurkat cells was inhibited by paclitaxel depended on the concentration apparently. Treated by paclitaxel for 48 h, P<0.05 and |log2(FC)|≥1 were used as filter criteria on the results of RNA Sequencing (RNA-Seq) and GeoChip, 351 DEGs were found from Jurkat cells, including 323 up-regulated genes and 28 down-regulated genes. The GO functional annotation and KEGG pathway enrichment analysis showed that the role of paclitaxel was mainly concentrated in protein heterodimerization activity, nucleosome assembly and transcriptional dysregulation in cancer, etc. The results of RT-qPCR were consistent with those of the sequencing analysis, which verified the reliability of this sequencing. CONCLUSION Paclitaxel can affect the proliferation and apoptosis of T-cell lymphoma by up-regulating JUN gene, orphan nuclear receptor NR4A family genes and histone family genes.
