Hepatic fibrosis is a wound-healing response to liver injury, which has complex celluar and molecular mechanisms. Animal models that similar to human hepatic fibrosis are important to explore further pathological mechanisms and more effective drug therapy for hepatic fibrosis. This article reviews recent progress in animal models and antifibrotic therapy related to hepatic fibrosis.

Indices of angiogenesis are increased in synovia from patients with rheumatoid arthritis, and vascu-lar proliferation may contribute to the pathogenesis of synovitis, pan nus growth, bone and cartilage destruction, and osteophyte formation. Many proan giogenic factors are expressed in the synovium in RA. They have been shown to ha ve important effects in the angiogenic process in RA. So the blockade of angioge nesis appears to be a promising avenue for the future treatment of RA.

Age-related macular degeneration ( AMD ) is one of the important eye diseases of the WHO present three big blindness, is one of the main blinding eye disease in people over the age of 50, people over the age of 65, about 2% of the disease caused by monocular blindness, as the population ages, AMD prevalence is increasing in our country. AMD with respect to its clinical manifestations can be divided into dry AMD and wet AMD, wet AMD is the most harmful for the vision of patients, at present there are many treatments for AMD ( mainly for wet age-related macular degeneration ) , mainly including laser treatment, drug therapy, surgical treatment, gene therapy, etc. The treatments of AMD would be illuminated in this article.

Objective To elucidate potential roles of tyrosine kinase 2 (Tyk2) in the generation and maintenance of Ag-specific CD8+ T cells. Methods We followed the fate of OVA-specific CD8 + T cells in Tyk2-deficient ( Tyk2 -/- ) mice after infection with recombinant OVA-expressing BCG ( rBCGOVA ). Because the immunostimulatory BCG-derived peptides recognized by CD8 + T cells have not been defined, and the OVA is definite peptide for specific CD8 + T cells that has been accepted widely, therefore we examine the kinetics of the OVA-Ag-specific CD8 + T cell response after rBCG-OVA infection in mice.Tyk2-/- and wild type(Tyk2+/+ ) mice were inoculated with rBCG-OVA by intra-trachea( i. t. ), after the examination of bacterial growth in the lung and spleen, the population of CD8 + T cells were detected by FACS analysis, the epitope-specific CD8 + T cells were followed with tetrameric H-2Kb molecule folding with OVA257 264 peptide, and the kinetics of Ag-specific CD8 + Tc1 cells were detected by intracellular IFN-γ production in response to OVA257-264 peptide by cytokine FACS analysis. Results After rBCG-OVA challenge,the bacteria number in spleen and lung of Tyk2 -/- mice were significantly larger than those in Tyk2 +/+ mice on days 14, 21 and 49. Almost as same as that in Tyk2+/+ mice, the size of epitope-specific CD8+ T cella with OVA257-264/Kb-tetramer-positive and the CD8 +Tc1 (T eytotoxic 1 )cells positive for intracellular IFN-γ could proliferate to its peak on day 21, then contract and maintain to the memory phase in spleen and lung of Tyk2-/- mice, but the population of CD8+ T cells in spleen and lung of Tyk2 -/- mice were significantly smaller than those in Tyk2+/+ mice on days 21 and 49, the number of epitope-specific CD8+ T cells in spleen and lung of Tyk2 -/- mice were significantly decreased and the frequency of CD8 + Tc1 cells in spleen and lung of Tyk2 -/- mice significantly reduced on day 21,49 and 70 after rBCG-OVA infection. So correspond with the larger number of bacteria in Tyk2-/- mice than those in Tyk2 +/+ mice, the expansion of OVA257-264-specific CD8 + T cells and CD8+ Tc1 response were attenuated in Tyk2 -/- mice following rBCG-OVA infection. Conclusion These results suggest that the lack of Tyk2 signaling impairs the proliferation and difference of effector CD8 + T cell to rBCG-OVA infection and at least, is partly responsible for the susceptible to the rBCG-OVA infection.

Tob1 is a member of Tob/BTG anti-proliferative proteins family. Studies have shown that Tobl involves in tumor development, embryonic development, hyperostosis, behavioral capacity and so on.Tobl is intimate with tumor occurrence and development, and plays an important role in suppressing tumor development. The article focuses on the biological characteristics of the Tob1 and its relationship with tumors.

ObjectiveTo investigate the efficacy of aerosol inhalation of Pulmicort Respules combined with urbason in treating severe bronchial asthma.MethodsThe clinical data of 40 cases aith severe bronchial asthma treated in our hospital were analyzed retrospectively,among which 20 cases underwent Pulmicort Respules combined with urbason(Tset Group),20 cases underwent urbason( Control Group).ResultsCompared with the control group,the blood gas analysis in test group had statistically significant difference before treatment (P ＜ 0.05 ).Compared with the control group,the clinical effect and the blood gas analysis in test group had no statistically significant difference after treatment(P ＞ 0.05 ).Compared with the control group,the complications in test group had statistically significant difference( P ＜ 0.05),the complications in test group was less than the control group.ConclusionAerosol inhalation of Pulmicort Respules can reduce the amount of urbason and lower the incidence d complications.The combination treatment of this two drugs can achieve the same clinical results alike the clinical effect of large doses of methy lprednisolone.

Expression of the T-type Ca2 + channels has been reported in numerous types of tumors due to their unique activation/inactivation properties. In some cancer cells, the expression of T-type Ca2+ channels is proliferation state dependent. T-type channel blockers or interfering the α1 subunit of this channel via siRNA decrease proliferation of these cells. Since T-type Ca2+ channels are not expressed in epithelial cells, selective T-type Ca2 + channel blockers maybe serve as a potential therapeutic approach in the treatment of certain types of cancers.

Objective: To investigate the mechanism of Chinese herbs in resisting chronic immobilization stress.Methods: The rat models of chronic immobilization stress were copied by merely constraint.Total RNA in hippocampus was extracted and primers of enkaphalin or prodynorphin were respectively added for RT-PCR reaction.Then the expressions of enkaphalin and prodynorphin in hippocampus were compared. Results: Enkaphalin mRNA and prodynorphin mRNA expressions in hippocampus markedly increased in chronic immobilization stress and the longer the more evident.Xiaoyao powder as well as decoction of four mild drugs were able to decrease the gene expression of enkaphalin mRNA,and all the three recipes were able to decrease the gene expression of prodynorphin mRNA,and the effect of Xiaoyao powder was obviously outweigh to Jinkuishenqi pill.Conclusion: enkaphalin and prodynorphin both participated in the regulation of hippocampus on stress;the regulation of endogenous opium system was one of the most important ways of the three recipes in accommodating stress.

Objective To establish a method for determining glutamate concentration in microamount cerebrospinal fluid after acute cerebral insult.Methods The concentration of glutamate in cerebrospinal fluid was measured in mice after acute cerebral insult by precolumn derivatization with O-phthaldehyde.Results The average recovery of glutamate was 84.26% to 125.6%(n=3),the relative standard deviation(RSD) in one day and three days was respectively less than 4.94%(n=3),0.78%(n=3).The concentration of glutamate in cerebrospinal fluid of mice 6 h after acute cerebral insult was significantly higher than that of sham operation mice(P

Objective:To study the effects of whole body vibration(WBV)on resistance fracture after postmenopausal obesity women.Methods:A 12-weeks prospective and randominzed trial of 100 postmenopausal women with body mass index(BMI)≥23.The subjects were exposed to three 10-minutes treaments/week,low-magnitude(2.0m/s)and 30Hz vertical accelerations.
