Immunosuppressive drugs used in organ transplantation are highly effective in preventing acute rejection. However,the clinical use of the drugs is complicated by the fact that they display highly variable pharmacokinetics and pharmacodynamics among in-dividual patients. The influence of genetic variation on the interindividual variability in immunosuppressive drug disposition,efficacy and toxicity has been explored in recent years. The review summarized all kinds of immunosuppressants and their relationship with ge-netic polymorphisms,including the SNPs of related enzymes about pharmacokinetics and pharmacodynamics,the SNPs of donor and tar-get site. The review focused on the current situation and progress in the related research areas.

Objective:To discuss the role of clinical pharmacists in avoiding, eliminating and alleviating the effect of medical dis-putes caused by adverse drug reaction ( ADR) and provide reflections and suggestions for the disputes. Methods:Clinical pharmacist participation in the treatment of one case of dispute caused by serious adverse drug reaction was described and analyzed. Results:Clini-cal pharmacists provided opinions and suggestions for the dispute, and promising effect was obtained. Conclusion: Clinical pharma-cists should have excellent medical knowledge and good communication skills, and medical personnel should closely monitor patients in order to avoid medical disputes caused by ADR.

Objective:To optimize the ethanol extraction process of Rhizoma Corydalis and Salvia miltiorrhiza, and study the effect of comminution degree of the medicinal materials on the effective constituent. Methods:Using the alcohol concentration, alcohol vol-ume, extraction time and extraction times as the impacting factors,the content of tetrahydropalmatine and salvianolic acid as the indi-ces, the extraction process was optimized by orthogonal test of L9(34). Results:The best extraction conditions were as follows:Rhizo-ma Corydalis was crushed into coarse powder, the material / liquid ratio was 1∶6 with 75% ethanol as the extraction solvent,extracting twice with 1. 5h each. Conclusion:The extraction method is appropriate and simple,and can be used in the industrial production.

Objective:To establish a method for the determination of Cu,As,Cd,Hg and Pb in spirulina health products. Meth-ods:The samples were digested by microwave and determined by ICP-MS.

Conclusion:The method is sensitive, simple and accurate, and can be used to determine the harmful elements in spirulina health products.

Objective:To evaluate the compatible stability of sodium nitroprusside for injection ( SNP) in two kinds of solutions (5% glucose and sodium chloride injections) . Methods:A, B, C and D solution of SNP was respectively prepared according to the concentration of clinical use. The stability of SNP solution was studied in different environment with different storing time, and the as-sessment indices included the appearance, insoluble particles, pH value, ultraviolet-visible absorption spectrum and SNP content. Re-sults:The SNP solutions in 5% glucose and sodium chloride injections were stable in 26 hours in photophobic condition at 20℃ and 35℃. Under an incandescent lamp with or without lightproof, the solutions were very unstable. Conclusion:Both sodium chloride and 5% glucose injections can be used as the solvent for SNP with 26h stability. SNP injections prepared and used in clinics should be pre-served away from light to ensure the safety and effectiveness.

Objective:To compare the contents of polysaccharide and protein in male and female Trichosanthis Radix to provide reasonable explanation for that male plant was better. Methods:Polysaccharides in Trichosanthis Radix were obtained by water-extrac-tion and ethanol-precipitation method, and the content was determined by anthrone-sulfuric acid method. Tichosanthin ( TCS) was ob-tained by hydrochloric acid extraction and acetone precipitation. Based on the light absorption of Coomassie brilliant blue G-250 com-bined with proteins, the content of TCS was detected. Results: The polysaccharides content in male and female Trichosanthis Radix was 2. 628% and 3. 237%, TCS content was 0. 193% and 0. 280%, respectively. Conclusion: The contents of polysaccharides and TCS in male plant are higher than those in female plant. The male plant is a better source for Trichosanthis Radix.

Objective:To investigate the efficacy and safety of metformin in the treatment of elderly patients with diabetes. Meth-ods:Totally 72 cases of elderly patients with diabetes in our hospital from January 2012 to December 2012 were randomly divided into the observation group and the control group. The observation group was received metformin, and the control group was given repaglin-ide. The efficacy and safety of the two groups were compared. Results:After the treatment, blood sugar of fasting, 2h after meals and 10:00 p. m. in the observation group and the control group was significantly decreased (P<0. 05), and blood sugar of fasting in the observation group was significantly lower than that in the control (P<0. 05), while that of the other time points was without significant difference (P>0. 05). The HbA1c levels before and after the treatment in the observation group was with statistically significant differ-ence (P<0. 05), and those in the control group was without significant difference (P>0. 05). The incidence of adverse reactions in the observation group was lower than that in the control group(P<0. 05). Conclusion:Effect of metformin in the treatment of elderly patients with diabetes is remarkable and safe, which is worthy of further promotion and application.

Objective:To study the efficacy of ribavirin injections combined with Tanreqing in the treatment of children with epi-demic parotitis. Methods:From January 2012 to September 2013, 128 children with mumps in our hospital were selected and random-ly divided into the treatment group and the control group with 64 cases in each. The control group was intravenously given ribavirin in-jections, 5-7. 5 mg·kg-1 , ivd, bid, and the treatment group was given Tanreqing injections additionally, 0. 25-0. 4 ml·kg-1 ·d-1 , ivd,qd. After the 5-day treatment, the extinction time of parotid swelling and pain, defervesce time and the decrease of TNF- α and CRP were observed in the two groups. Results: The total effective rate in the treatment group was 93. 8%, which was significantly higher than that in the control group (84. 4%) with significant difference (P<0. 05). The extinction time of parotid swelling and pain and defervesce time in the treatment group were significantly shorter than those in the control group (P<0. 05). After the treatment, TNF- α and CRP in the two groups were significantly decreased (P<0. 05), and the decrease in the treatment group was much notable than that in the control group (P<0. 05). Conclusion:Ribavirin injections combined with Tanreqing in the treatment of children with mumps can significantly shorten the extinction time of parotid swelling and pain and defervesce time, and inhibit TNF-αand CRP with significant effect, which is valuable in clinical promotion and application.

Objective:To investigate the effect of live lactobacillus preparation in the treatment of postpartum vagina microenviro-ment dysbiosis. Methods:Totally 300 cases of postpartum women were selected in our hospital from February 2013 to November 2013, including those with normal delivery, cesarean section and vaginal delivery after lochia, and each was with 100 cases. The vaginal se-cretion was withdrawn from vagina and the microenvironment was assessed. The patients with dysbiosis were randomly divided into two groups, the observation group was treated with living lactobacillus preparation and the treatment group was without treatment. The effi-cacy and incidence of bacterial vaginosis(BV) were observed. Results:Totally 88 cases (29. 3%) occurred vaginal dysbiosis. There were significant differences in the dysbiosis incidence rate, pH, H2 O2 results, microscopic examination results and the distribution of flora between the two groups (P <0. 05). The effective rate of the observation group was 95. 5%, which was significantly higher than that of the control group (29. 5%). The incidence rate of BV was 4. 5% in the observation group, which was significantly lower than that in the control group [75%] (P<0. 05). Conclusion: The effect of the lactobacillus preparation in the treatment of postpartum vagina microenviroment dysbiosis is promising and safe.
