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 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.

Diabetic macular edema (DME) is a common complication of diabetes that can lead to severely impaired visual acuity.Its pathogenesis is complex,which is closely related to the destruction of blood-retinal barrier,and there are many cytokines involved in its formation,but the exact mechanism is not yet fully clear.Recent researches suggested that some typical pathological characterizations of retina can be used as criteria for evaluating its occurrence,and it is known that a variety of risk factors participated in the pathological process,such as glucose,blood pressure,blood lipids,which are well-known and can be closely correlated with its development through impacting the systemic and retinal vascular functions by complex mechanisms and leading to endothelial dysfunction.While other systemic risk factors,such as diabetic nephropathy which leads to changes in osmotic balance,anemia which increases cytokines caused by ischemia and hypoxia,excessive body weight which leads to vascular damage through fat factor,smoking that produces blood vessel damage by promoting oxidative stress on the body and various hypoglycemic drugs,will influence the development of macular edema on different levels.So conducting a comprehensive and newest understanding of this disease and its risk factors are conducive to better prevention efforts for diabetes patients.This review mainly summarizes the latest researches on definition,classification,pathologic characterization and risk factors of DME.

Objective Analyzed 32 cases of gastrointestinal stromal tumors(GIST) patients,to analysis the clinical and pathological characteristics of gastrointestinal stromal tumors of the stomach and explore associated prognostic factors.Methods Thirty-two GIST patients confirmed pathologically were included from May,2007 to April,2013.Their clinical records were retrospectively analyzed.Results Of the 32 GIST patients,the overall survival (OS) is 85.3％ for the second year.The progression free survival (PFS) is 79.2％ for the second year,respectively.Univariate survival analysis showed that OS and PFS have significant association with tumor size,metastasis,mitotic index and NIH risk group.Conclusions Metastasis and NIH risk group both are potential prognostic factor for gastric GIST.

Objective To observe the clinical effect of orally montelukast combined with doxofylline in older bronchial asthma.Methods A total of 87 stationary phase older bronchial asthma patients were divided into trial group (44 cases) and control group (43 cases).Trial group was given orally montelukast 10 mg 1 time/d,doxofylline 0.2 g,2 times/d.Control group was given inhaled fluticasone 250 μ g,2 times/d,a total of 3 months.The forced expiratory volume in one second (FEV1),peak expiratory flow rate (PEFR),one second rate (FEV1/FVC),asthma control test (ACT) score and the adverse reaction were compared between the 2 groups.Results There were no significant differences in FEV1,PEFR,FEV1/FVC before treatment between the 2 groups (P ＞ 0.05),they were significantly improved after treatment [trial group:(2.20 ± 3.21)L vs.(1.68 ± 0.71) L,(3.97 ± 0.32) L/s vs.(3.27 ± 0.32) L/s,(76.18 ± 1.02)％ vs.(63.91 ± 1.40)％,control group:(2.24 ±0.75) L vs.(1.71 ± 1.58) L,(4.06 ±0.34) L/s vs.(3.29 ±0.28) L/s,(77.85 ±0.67)％ vs.(62.37 ± 1.29)％],there were statistical differences (P ＜ 0.05).But there were no statistical differences after treatment between the 2 groups (P＞ 0.05).According ACT score,total effective rate in trial group was 90.9％ (40/44),in control group was 95.3％(41/43),there was no statistical difference (P ＞ 0.05).The rates of adverse reaction in trial group and control group were 4.5％(2/44) and 7.0％(3/43),there was no statistical difference (P ＞ 0.05).Conclusions The curative effect of orally montelukast combined with doxofylline in older bronchial asthma closes to the classic solution of inhalation fluticasone,which is easily accepted by older patients,and safety.It provides another option for older bronchial asthma patients.

Polo-like kinase 1 (Plk1) is a serine/threonine kinase that is widely expressed in eukaryotic cells and a key regulator of the cell mitosis.During different stages of mitosis,the locations of Plk1 in cells are different,and can interaction with different substrates,thus it has many biological functions.This article focuses on the functions of Plk1 in different mitotic stages.

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.

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.
