Objective:To establish the quality standard for Chuipencao tablets. Methods:Sedum sarmentosum Bunge was identi-fied by TLC. Quercetin, kaempferol and isorhamnetin were determined by HPLC. Results: The method of TLC was highly specific. The linearity was obtained within the range of 4.94-98.82 μg·ml-1(r =0.999 9) for quercetion, 4.94-98.82 μg·ml-1(r =0.999 9) for kaempferol and 1.07-21.36 μg·ml-1(r=0.999 9) for isorhamnetion. The average recovery was 103.1%(RSD =2. 2%,n=6), 100. 6%(RSD=2. 0%,n=6) and 100. 1%(RSD=2. 0%,n=6), respectively. Conclusion: The method is accu-rate with good reproducibility, which can be used as the quality control for Chuipencao tablets.

OBJECTIVE: To provide reference for patients with type I incisions about rational use of antibiotics.METHODS: Between Oct.2007 and Mar.2008,a total of 1 024 medical records of patients with type I incisions from orthopaedics,common surgery,department of gynecology in 12 hospitals of Xining area were sampled for analysis of prophylactic use of antibiotics.RESULTS: 100.0% of the type I incision patients received prophylactic antibiotics;28.4% used antibiotics without indication;16.9% used antibiotics at 0.5~2 h before operation;33.4% used antibiotics at more than 2 h before operation;and 49.7% received antibiotics postoperatively rather than preoperatively.The irrational and nonstandard use of antibiotics manifested as improper in the choice of drug variety,nonstandard in drug combination,irrational in dosage and administration,prolonged use of antibiotics,lacking basis for the change of drug variety etc.CONCLUSION: The prophylactic use of antibiotics in patients with type I incisions from 12 hospitals of Xining area is far from perfect,therefore,it is urgent to strengthen the standard management on the use of antibiotics.

Objective To build rat orthotopic liver transplantation model and use this model as an experimental animal model for further research about liver transplantation.Methods Based on the classic two-cuff technique,a variety of skills were integrated,such as abdominal aorta perfusion first before ligation,suprahepatic inferior vena cava single continuous suture,preoperative and postoperative rehydration,hepatic portal vein and infrahepatic vena cava blocked by mosquito's haemostatic forceps.At last,the postoperative survival rates of 2 days and 2 weeks were recorded.Results Donors' operation time was (35±2) min,cuffing time was (7.0±1.5) min,receptors' operation time was (80±15) min,anhepatic phase was (21±3) min.The 2-day survival rate was 92 % (46/50) and 2-week survival rate was 86 % (43/50).Conclusion To some extent,the improved methods can not only reduce the difficulty of orthotopic liver transplantation operation,but also to create a uniform,stable and reliable orthotopic liver transplantation model.

This study was aimed to screen out an optimal pharmaceutical formulation of Wuji Gastric Floating Sus-tained-release Tablets. With multicomponents of release for index, the extra-floating ability of the tablets was stud-ied with the orthogonal test of four excipients, which were HPMC (K100M), PEG 6000, sodium bicarbonate and se-tanol. The results showed that the combined optimal pharmaceutical formulation was 35% HPMC, 5% PEG 6000, 10% sodium bicarbonate, 15% setanol, 10% MCC and 25% main drug. It was concluded that Wuji Gastric Floating Sustained-release Tablets had the characteristics of slow-release and long floating duration which comply with re-quirements of formulation design. This preparation technique is with good maneuverability.

Objective This study has explored the role of antibody against annexin A2 in patients with antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). Methods Using purified recombinant annexin A2, IgG anti-annexin A2 antibody was measured by ELISA in 101 APS patients, 41 SLE patients with thrombosis, 124 SLE patients without thrombosis and 120 healthy controls. Results The positive rate of IgG anti-annexin A2 antibody in APS patients and SLE patients with thrombosis was 21.8%, 26.8%, respectively, they were all significantly higher than in SLE patients without thrombosis (6.5%). IgG anti-annexin A2 antibody was associated with thrombosis and/or pregnancy morbidity (P<0.01). Conclusion Anti-annexin A2 antibody is associated with thrombosis and/or pregnancy mnrbidity. It suggests that anti-annexin A2 antibody may be helpful in identifying in some potential AIRS.

Objective To evaluate and compare the diagnosis and treatment quality of 15 tertiary hospitals in Beijing with the quality-evaluation model of STEMI.Methods The quality-evaluation model has been formatted with the document analysis method and expert consultation method,with the indicators weighted by analytic hierarchy process.By collecting the data of 15 hospitals,we can get the values of indicators,then synthetically evaluate and compare the diagnosis and treatment quality at these 15 hospitals with the method of WRSR.Results In the diagnosing and treating the cases of STEMI at the hospitals,gaps are found between the clinical guidelines and the tests,patient evaluation,reperfusion treatment and drug therapy,with some indicators falling even below 22%.Also,there are significant differences in the diagnosis and treatment quality among hospitals.All hospitals are consistent on the five dimensions-tests,patient evaluation,reperfusion treatment,drug therapy and prognosis.Conclusion The quality-evaluation model of STEMI can comprehensively reflect the diagnosis and treatment quality of cardiovascular medicine,and partly reflect hospital's overall management level,so as to provide operating methods in improving hospital diagnosis and treatment quality.

This article was aimed to study the multicomponent in vivo releasing rules of Zuojin Gastric Floating Sus-tained-release Tablet. Stomach contents of rabbits were collected at different times and then prepared into solutions for the study. The HPLC was used to establish fingerprints of each time and fingerprints of completely dissolved samples. The in vivo releasing rates were calculated. The evaluation was made on releasing behaviors among index components as well as between index components and preparations. The results showed that within 10 h, the f2 of berberine and limonin, rutaecarpine, preparation were 52, 61.5, 66.4, respectively. The f2 of limonin and rutae-carpine, preparation were 70, 46.5, 53.7, respectively. It was concluded that within 10 h, the releasing behavior of berberine and limonin, rutaecarpine, preparation was similar. The releasing behavior of rutaecarpine and limonin, preparation was similar. However, the releasing behavior of limonin and preparation was different.
