Objective:To observe the clinical effect of self-prescribed Zuoyu No. 2 (ZY2) in the treatment of anal eczema after complex anal fistula operation. Methods: Totally 100 patients were randomly divided into two groups, the patients in the treatment group were given ZY2 combined with the conventional wound dressing treatment after defecation everyday, while the patients in the con-trol group were treated with washing infection area with warm water followed by applying triamcinolone acetonide and econazole creams on the lesion or itching skin combined with the conventional wound dressing after defecation everyday. Results:The efficiency rate in the treatment group was higher than that in the control group (82. 0% vs 60. 0%, P<0. 05), the total effective rate in the treatment group was also significantly higher than that in the control group (100% vs 90. 0%, P<0. 05). The anal pruritus disappearance time and the skin lesion recovery time in the treatment group were better than those in the control group(P<0. 05). Conclusion:ZY2 has a good clinical curative efficacy in the treatment of anal eczema after complex anal fistula operation with improvement of clinical symp-toms, which is worthy of promoted application.

Objective:To observe the clinical effects of Zuoyu üo. 1(ZY1)in the prevention of concomitant concurrent complica-tions after operation for anorectal diseases. Methods:164 patients who had received operation for anorectal diseases were randomly di-vided into 2 groups. Patients in the treatment group were treated with sitz baths in ZY1 and the conventional wound dressing method. Patients in the control group were treated with sitz baths in warm water and the conventional wound dressing method. Results:The effi-ciency rate of the treatment group was significantly higher than that of the control group(53. 57% vs. 27. 5%,P<0. 05),as well as the total effectiveness(95. 23% vs. 88. 75%,P<0. 05). The comparison showed that better curative effects existed in the treatment group on distress,bleeding,and edema ratings and wound healing time. Conclusion:Sitz bath in ZY1 after operation for anorectal dis-eases reduces complications and shortens the wound healing time without any side effect. It is thus extensively promising in clinical ap-plications.

OBJECTIVE:To investigate the effect of clinical pharmacist intervention on prophylactic application of antibiotics in cardiothoracic surgery. METHODS:Medical records of patients underwent cardiothoracic surgery were collected from our hospi-tal during Mar. to Apr. in 2014 (before intervention) and during Jun. to Jul. in 2014 (after intervention). Those were divided into pre-intervention group(n=115)and post-intervention group(n=119). The prophylactic application effect of antibiotics was com-pared before and after intervention. RESULTS:After intervention,the rates of prophylactic application were decreased significantly from 96.5% to 72.3%;the rationality rate of antibiotics selection was improved significantly from 27.9% to 94.2%;The course of prophylactic medication decreased significantly from(5.4±2.8)days to(2.3±1.8)days;the difference had statistical significance before and after intervention(P<0.01). The postoperative infection rate was decreased from 13.0% to 5.9%,the difference had no statistical significance(P=0.074). The average hospitalization time,average drug costs,and average hospitalization expenses were decreased significantly,the difference had statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Clinical pharmacist inter-vention to prophylactic application of antibiotics in cardiothoracic surgery can control the infection effective and guarantee reason-able and safe use of drugs during perioperative period.

Objective To prepare recombinant human prothrombin-2 expressed in Pichia pastoris, and assay the enzymatic and clotting activities of prothrombin-2 activated by prothrombin activator ecarin.Methods Human prothrombin-2 gene and Echis carinatus ecarin gene were synthesized separately on the basis of the cDNA sequences published in GenBank.The gene of prothrombin-2 was cloned into the expression vector pPICZαA.The expression vector pPICZαA/prothrombin-2 was transformed into glycoengineered P.pastoris, and then prothrombin-2 engineered P.pastoris was screened.The expression products were induced by methanol, purified by two-step chromatography and identified by diges-tion by PNGase F and analysis of pepetide fingerprint.The ecarin gene was cloned into the expression vector pcDNA3.1. The expression vector pcDNA3.1/Ecarin was transformed into HEK 293T cells and the culture supernatant of HEK 293T/Ecarin was collected.The reaction product of HEK 293T/Ecarin cell culture supernatant and purified prothrombin-2 was analyzed by S-2238,which was the chromogenic substrate for thrombin.Fibrinogen was used to measure blood clotting time. Results The purified protein of P.pastoris expressed prothrombin-2 culture supernatant was 37 ×103 .The relative molecular mass(Mr) of the purified protein was reduced to 35 ×103, which was consistent with the theoretical Mr of prothrombin-2 molecular weight.The purified protein was proved to be prothrombin-2 by peptide fingerprint identification. The purified prothrombin-2 processed by HEK 293T/Ecarin culture supernatant could hydrolyze S-2238 to produce yellow pNA, and D405 of pNA increased with the volume of the processed prothrombin-2 that could promote the plasma coagulation.The blood clotting time was close to that of the thrombin kit.Conclusion Prothrombin-2 is prepared by P.pastoris and activated toα-thrombin by ecarin.This technique may replace the method of extraction of prothrombin from plasma and can be used for the treatment of war wounds or for future clinical research.

Objective:To evaluate the effect of continuing intervention on prophylactic application of antibiotics in sterile operation in urology department by clinical pharmacist to provide reference for the clinical prophylactic application of antibiotics. Methods:All cases of discharged patients underwent sterile operation in urology department of our hospital from July 2010 to June 2014 were divided into three groups according to the intervention time and methods: non-intervention group(n=141), stage Ⅰ intervention group(n=139), stage Ⅱ intervention group (n=162) and stage Ⅲ intervention group (n=137). The prophylactic application of antibiotics was statistically analyzed. Results:After the continuing intervention, the prophylactic application rate of antibiotics in the three inter-vention groups was decreased significantly from 100% before the intervention respectively to 34. 5%,18. 5% and 14. 6% after the in-tervention (P<0. 01). The rationality rate of prophylactic application was improved significantly from 36. 9% before the intervention respectively to 58. 3%, 63. 3% and 85. 0% after the intervention (P<0. 01). The course of prophylactic application was decreased significantly from (138.2 ±31.6)h respectively to (89.9 ±48.0)h,(72.8 ±32.5)h and(45.1 ±29.5)h (P<0.01) and the post-operative infection rate was decreased from 2. 8% respectively to 2. 1%,1. 8% and 1. 4%. Conclusion:The pharmaceutical interven-tion is feasible and valid to improve the rational prophylactic use of antibiotics in urological surgery.

BACKGROUND:Previous studies have found that the susceptibility genes of adiponectin gene and calpain 10 gene of type 2 diabetes are closely related with the incidence of diabetes in Chinese renal transplantation patients. So, are other susceptibility genes of type 2 diabetes also associated with posttransplantation diabetes mel itus? OBJECTIVE:To investigate the association between the zinc transporter solute carrier family 30 member 8 (SLC30A8) gene polymorphism and the posttransplantation diabetes mel itus. METHODS:A total of 97 patients with posttransplantation diabetes mel itus and 301 patents without posttransplantation diabetes mel itus (control group) were selected, and then the SLC30A8 gene rs13266634 genotype was detected with real-time PCR method. The association between gene polymorphism and posttransplantation diabetes mel itus was analyzed with Logistic regression test. RESULTS AND CONCLUSION:There were significant differences in al ele frequencies and genotype distributions of rs13266634 between the patients with and without posttransplantation diabetes mel itus (P<0.05). After adjustments of age, sex, body weight and body mass index, the incidence of posttransplantation diabetes mel itus of the CC genotype patients was 2.108 times to that of the TT genotype patients (odds ratio=2.108, 95%confidence interval:1.075-4.131, P=0.044);and the incidence of posttransplantation diabetes mel itus of the CC+CT genotype patients was 1.862 times to that of the TT genotype patients (odds ratio=1.862, 95%confidence interval:1.049-3.306, P=0.034). The results suggest that the C-al ele in rs13266634 of SLC30A8 gene is the independent risk factor of posttransplantation diabetes mel itus.
