OBJECTIVE:To provide reference for rational use of drugs in hospital under the condition of the separation of drug and medical care. METHODS:The volumes of business,income from drug and income condition of medical staff were compared before and after implementation of separation of drug and medical care. The chance for pharmaceutical work under the condition of the separation of drug and medical care were analyzed to put forward advice for improvement of drug use in medical institutions. RESULTS & CONCLUSION:After conducting Wuhu model in 8 medical institutions,some achievement and experience have been obtained. It should be propelled to implement effective administration for rational use of drugs to resolve the problems on over expensive medical service.

Objective To observe the general status and the immunity of DBA/2 mice injected with leukemia vaccine during the immune reconstitution, and to observe the survival rate of these injected mice that were then challenged by L1210 cells. Methods Normal mice and reconstituted lymphopenic mice (RLM; DBA/2 mice rendered lymphopenic with sublethal irradiation and reconstituted with naive splenocytes) were used in the vaccination and challenge experiments with L1210 cells. Results Following vaccination, a significant increase of the IFN-? was detected in the blood of vaccinated RLM compared with that of vaccinated normal mice, as assessed by ELISA. Significantly, greater protection was induced in vaccinated RLM, which led to a stronger protection from death. Conclusion The vaccination of reconstituted lymphopenic hosts could elicit superior anti-tumor immunity compared with normal hosts, highlighting the potential clinical benefit of performing tumor vaccination during immune reconstitution.

OBJECTIVE:To study the effects of spirulina kinase(SPK)on the vascular endothelial function of model rats with atherosclerosis. METHODS:60 rats were randomly divided into normal control group(distilled water),model group(distilled wa-ter),positive control group(simvastatin,0.005 g/kg)and SPK low-dose,medium-dose,high-dose groups(80,160,320 U/kg). Except for normal control group,rats in other groups were induced for model of atherosclerosis. All groups were intragastrically ad-ministrated relevant medicines at the same time,once a day for consecutive 12 weeks. Total cholesterol(TC),triglyceride(TG), low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α) contents in serum of rats were measured. And the changes of thoracic aortic endothelium morphology were ob-served by HE staining. RESULTS:Compared with normal control group,TC,TG,LDL-C,IL-6,TNF-α contents in serum of rats in model group were increased(P<0.01),HDL-C content in serum was decreased(P<0.01);vascular endothelial cells fell off, intimal proliferation projected into the lumen,smooth muscle cell proliferated and disordered,medium film elastic fiber disintegrat-ed and fractured. Compared with model group,TC,TG,LDL-C,IL-6,TNF-α contents in serum of rats in administration groups were decreased(P<0.05 or P<0.01),HDL-C content in positive control group and SPK medium-dose,high-dose groups was in-creased (P<0.05). Vascular endothelial cell morphology was improved significantly in administration groups,in which,vascular endothelial cells were structurally intact in SPK medium-dose,high-dose groups,inner membrane was basically smooth;medium smooth muscle cells arranged slightly disordered in SPK medium-dose group. Compared with normal control group,there were no obvious changes. CONCLUSIONS:SPK shows obvious lipid-lowering and anti-inflammatory effects,it can protect vascular endo-thelial function. The mechanism may be related to reducing TC,TG,LDL-C,HDL-C,IL-6,TNF-αcontents and increasing HDL-C content in serum.
