MicroRNAs (miRNA) plays an important role in biological development and disease occurrence and development, and acts as a "main switch" in biology. Among patients of essential hypertension, around 1/3 would suffer left ventricular hypertrophy (LVH). Hence, essential hypertension becomes an independent risk factor for cardiovascular diseases. And miRNAs plays an important role in the occurrence and development of LVH. This paper reviewed the role of miRNA in regulating the stress signaling pathway, defined its impact on the occurrence of LVH, and further emphasized the opportunities and challenges of miRNA as a biomarker and therapeutic target.

Objective: To study the effect of tripterygium wilfordii polyglycosidium (TWP) on atopie dermatitis (AD) by detecting the expression of IL-2,IL-4,IFN-γ and IL-IO mRNA. Methods: RT-RCR was used to detect the mRNA of IL-2,IL-4, IFN-γ and IL-10 in peripheral blood mononuelear cells (PBMC)of AD cultured with different concentrations of TWP.ResuRs:(1)The expression of IL-2 was significantly different between the high concentration group and other groups(P<0.05 or P<0.01 ), and between the control group and the middle concentration group (P<0.01). (2)The expression of IL-4 was significantly different between the three different concentration groups (P<0.01 ). (3) The expression of IFN-γmRNA was significantly different between the high concentration group and the control, the low, the middle concentration groups (P<0.05 or P<0.01 ). (4)There was no significant difference in expression of IL-10 mRNA between the high concentration group and the middle concentration group (P>0.05), there was significant difference among the other groups (P<0.05 or P<0.01).Conclusion: TWP can suppress the expression of IL-2, IL-4, IFN-γand IL-10 mRNA, but the low concentration of TWP can suppress the high-level expression of IL-4 and IL-10mRNA in vitro.

To obtain a number of extracellular penicillinase,the gene(penp)encoding penicillinse of Bacillus cereus ATCC10987 was cloned into expression vector in Bacillus subtilis,transformed into Bacillus subtilis DB104 deficient in two proteases.When recombinant bacteria was cultured in LB medium for 24 hours,the result of SDS-PAGE showed that the molecular weight of the protein was 28kDa and the penicillinase activity reached 339U/ml.By screening seven different fermentation media,the result showed that 4# medium is favorable to producing penicillinase by the recombinant cells than the others,with the yield of the enzyme being 1580U/ml.When the recombinant cells was cultured in 7 liter fermentor for 24h,the penicillinase activity reached 1255.8U/ml.

For the employment orientation of graduates in clinical medical major from three-year medical eduction,a curriculum system,which will be used to foster practical medical talented person for urban and rural communities,has been proposed in this paper.We will take measures,which not only further defines training target and requirement for the practical medical person from the short school system and guides students to alterate their ideological concept but also reconstructures new curriculum system and reforms teaching methods,to ensure the implementation of the training objectives

Steroidal saponins have a wide range of pharmacological effects and biological activities, such as anti-tumor, antifungal, hypoglycemic, immune regulation, insecticides, etc. In the last ten years, some new structures of steroidal saponins compounds were found from natural plants, they have some new and different activities. In order to accelerate the research on the drug innovation of steroidal saponins, we summarized the new progress of the research on such compounds.

To investigate the effect of Tanreqing injection on immune activity of peripheral blood lymphocytes of patients with lung cancer. The peripheral blood lymphocytes of patients with lung cancer and healthy persons were separated by the density gradient centrifugation method for subsequent experiments, with those from healthy persons as the positive control. The effect of Tanreqing injection on stimulating the proliferation of lymphocytes with phytohemagglutinin (PHA) was determined by MTT method. The effect of Tanreqing injection on the lymphocyte secretions of IFN-γ and TNF-α and the subset ratio of lymphocytes cultured separately or with Tanreqing injection of different concentrations were examined by ELISA and flow cytometry (FCM) respectively. In addition, the LDH release assay was used to detect the cytotoxicity of cytotoxic T cells (CTL) and natural killer cells (NK). According to the findings, all of immunological indexes of lymphocytes from patients with lung cancer were weaker than that of healthy persons, but with the obvious increases in proliferation activity and IFN-γ and TNF-α secretions of lymphocytes co-cultured with Tanreqing Injection (P < 0.05). Among lymphocyte subsets co-cultured with Tanreqing Injection, CD3+, CD3+ CD4+ and CD3- CD16 + 56+ cell ratios notably increased, whereas CD4+ CD25+ Treg cell ratio obviously decreased (P < 0.05). In the meantime, Tanreqing injection can markedly promote the cytotoxicities of CTL and NK (P < 0.05). In conclusion, Tanreqing injection shows a significant effect in promoting the immune activity of lymphocytes from patients with lung cancer and their anti-tumor immunity.

BACKGROUND: Venous thromboembolism (VTE), including both deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common, lethal disorder that affects hospitalized and non-hospitalized patients. This study aimed to review the progress in the research into VTE. DATA SOURCES: We reviewed the studies about VTE and verified different genetic polymoriphisms of VTE. RESULTS: The pathogenesis of VTE involves hereditary and acquired factors. Many studies indicated that the disorder of coagulation and fibirnolytic system is of utmost importance to this disease. Genetic polymoriphism-related VTE demonstrated significant differences among geographies and ethnicities. CONCLUSION: VTE has many risk factors, but genetic factors play an important role.

OBJECTIVEA simple and effective therapy for single side constricted ear.
METHODSTransplanting normal side free composite auricular grafts to constricted ear (15 patients and 15 sides), then lengthening the helix, exposing the scapha, correcting deformity.
RESULTSThe 15 patients composite grafts all survived. The helix has been lengthened, the scapha exposed, the normal ear reduced, the constricted ear augmented and two sides ear have become symmetry.
CONCLUSIONThis method is simple and results are satisfied.
