Acid-sensing ion channels (ASICs), which are activated by extracelluar H+, are H+-gated cation channels. At present, seven subunits of ASICs family have been identified. Numerous studies revealed that ASIC1a plays important roles in synaptic transmission and plasticity,spatial learning and memory, nociception, as well as cerebral ischemia under physiological and pathological conditions. This review concerns the latest research about ASIC1a to promote the understanding of its physiological and pathological functions.

CENP-Fisacell-cycledependentkinetochoreprotein,whoseexpressionandlocalization patterns are regulated in a cell cycle-dependent manner.CENP-F plays an important role in the development and progress of malignant tumor.The expression of CENP-F is up-regulated in many tumors.It serves as an important marker in cell proliferation.Studies have demonstrated that CENP-F is involved in tumor genesis, progress,invasiveness,relapse and prognosis.CENP-F might be a valuable prognostic marker and potential therapy target in cancer treatment.

Objective To understand the cognitive status of urology medical staff about hematuria color.Methods The self-designed questionnaire about color cognition was adopted,and the concentration of hematuria samples were determined.The investigation was carried out in 50 health care workers about their cognition of hematuria color.Results The study found that there were differences in color perception between doctors and nurses,doctors and nurses with different titles,doctors and the standard sample,nurses and the standard sample.Conclusions There are differences in judgment and description of the urine sample color in medical personnel,they are more attempted to judge by virtue of work experience and subjective consciousness.Due to the lack of a uniform and objective standards,the medical staff can not accurately and objectively describe the development of patients' condition,thus patients' recovery was affected.Therefore,a unified objective criteria for clinical reference norms of hematuria should be developed as soon as possible to ensure that patients recover quickly and safely.

Positive and meaningful exploration was conducted by related teachers to improve the teaching quality of oral clinical pharmacology.Case based teaching method was applied in the teaching of adverse reactions and bilingual teaching was employed in the teaching of local anesthesia.Correlation and comparison of the key knowledge points were emphasized in the teaching process. Students′ interests were aroused and satisfactory results were achieved through implementing these measures.

Objective Observing the clinical effect of Ligustrazine Phosphate Tablets combined with percutaneous intratumoral injection of lipiodol THP on advanced hepa-tocellular carcinoma.Methods83 patients with advanced hepatocellular carcinoma from January 2012 to September 2014 were analyzed.Double-blind, randomized method All patients were divided into the control group 41 cases and observation group 42 cases.The control group were treatedwith percutaneous transhepatic intratumoral injection of lipiodol THP, the observation groupwere given Ligustrazine Phosphate Tablets combined with percutaneous intratumoral injection of lipiodol THP to treat.After treatment, the two groups of patients with treatment efficacy, adverse reactions and Karnofsky and prothrombin time were analyzed.ResultsAftertreatment, the efficacy of the two groups of patients were compared, the results showed that patients in the observation group total effective rate of the control group (χ2=4.034),the difference was statistically significant (P<0.05);two groups adverse reactions in patients after treatment were compared, liver pain, blood toxicity, fever, gastrointestinal reactions similar proportion of patients, the difference was not statistically significant;Theproportion of patients in the observation group AFP<8.1ng/mL was significantly higher (χ2=4.338), the difference was statistically significant (P<0.05);patients were observed after treatment Karnofsky score was significantly higher, the difference was statistically significant (t=7.141, P<0.05);after two groups of patients were compared prothrombin time, the difference was not statistically significant.ConclusionHepatic arterial chemoembolization and percutaneous intratumoral injection of THP lipiodol emulsion on the basis of the combination of Ligustrazine Phosphate Tablets can effectively improve the efficacy of treatment, and has good security, which is a safe and effective methods of treatment should be to promote and use in clinical.

In recent years,the study about the mechanisms of cell apoptosis has been increasingly concerned.Many liver diseases are correlated with caspase family,such as hepatic ischemia/reperfusion injury、inflammation and cancer,etc.In the article,we reviewed the importance of caspase family and the new research on the mechanisms of hepatic cell apoptosis in liver diseases.Meanwhile,we summarized the evidence concerned with apoptosis,and discussed the knowledge of therapeutic strategies.

Objective:To develop an HPLC method for the content determination of paeoniflorin, tetrahydropalmatine and osthole in Gujinwan capsules. Methods:The determination was performed on an Eclipse XDB-C18 column (250 mm × 4. 6 mm,5 μm) with the mobile phase consisting of 0. 1％ phosphoric acid (adjusting pH to 6. 6 with triethylamine)-acetonitrile with gradient elution. The flow rate was 1. 0 ml·min-1 . The column temperature was 30 ℃. The detection wavelengths were set at 230 nm and 280 nm. Re-sults:The calibration curves were found to be linear within the range of 9. 56-33. 65 μg· ml-1 for paeoniflorin(r=0. 9998), 3. 65-12. 86 μg· ml-1for tetrahydropalmatine(r=0. 9999) and 5. 81-20. 45 μg· ml-1for osthole(r=1. 0000). The average recovery of paeoniflorin, tetrahydropalmatine and osthole was 98. 8％(RSD=1. 1％), 98. 4％(RSD=0. 8％) and 99. 1％(RSD=1. 4％)(n=6),respectively. Conclusion:The method is simple, accurate and reproducible, which can be used for the quality control of Gujinwan capsules.

AIM: To investigate the transfection efficiency of mouse liver with non-viral vector containing manganese superoxide dismutase (Mn-SOD) gene. METHODS: The eukaryotic expression vector, gWiz/Mn-SOD, encoding human manganese superoxide dismutase was constructed. The plasmids of gWiz/Mn-SOD were mixed with cationic lipids, followed by injection into mice via branch of superior mesenteric vein, to induce Mn-SOD over-expression in murine liver detected by RT-PCR, Western blotting, SOD activity and immunohistochemical staining. RESULTS: gWiz/Mn-SOD transfection resulted in the obvious expression of exogenous Mn-SOD mRNA and protein in hepatic tissues at 8 hours after injection, and elevated mitochondria SOD activity 8.4 times in transfected hepatocytes than that in non-transfected cells at 72 hours after injection. It was showed that nearly 70% of mouse hepatocytes was obviously Mn-SOD positive after transfection. CONCLUSION: High expression efficiency of Mn-SOD gene in mouse liver is achieved safely by injection of gWiz/Mn-SOD and cationic lipid mixture into branch of superior mesenteric vein. [

Objective To establish a gas chromatography method which will be suitable for determination of one time of the benzene, toluene, dimethylbenzene in the adhesives. Methods DMF was used for dissolving the sample, polyethylene glycol chrom-atographic column, hydrogen flames detector gas chromatography were employed to separate the compounds, determine the nature of serve time, quantify apex area.

Conclusion The method is accurate, feasible and suitable for determination of the benzene, toluene, dimethylbenzene in the adhesives.

Objective To analyze the related factors of medical order compliance in patients with chronic prostatitis. Methods 482 patients with chronic prostatitis were investigated by using the National Institutes of Health chronic prostatitis symptom index(NIH-CPSI)、Eysenck personality qusetionnaire( EPQ)and the self-de-signed medical order compliance questionnaire and the patients' disease characteristics and personality were also analyzed.The related factores of medical order compliance in patients were analyzed through hierarchical multiple regression analysis. Results Patients with chronic pwstatitis were younger and their disease condition was seri-ous. Their personality was introverted. They had many psychological problems, such as anxiety, depression, sus-pect, et al. All these were related with patients' compliance. Conclusions Attention should be paid to the patients' personality, and psychotherapy should be given to patients with introverted personality to improve pa-tients' compliance,so that the treatment effect will be increased for patients with chronic prostatitis.
