P17 Pharmacology in the integrated course ＂Basic Medical Sciences＂ in Zhejiang University School of Medicine

According to traditional teaching mode, the courses in preclinical medicine including pharmacology are separately run. This mode causes a series of disadvantages including loose connection between knowledge in different disciplines and weak ability to bridge basic preclinical knowledge and clinical practice. In order to overcome the disadvantages and promote the teaching efficiency, we constructed a new integrated course-Course of Basic Medical Sciences, which includes 6 traditional courses, anatomy, histology and embryology, physiology, pathology, pathophysiology and pharmacology. We integrated these courses based on the human organ systems and according to the principle-＂ From macro to micro, From morphological to functional, From normal to abnormal and From disease to drug therapy＂ and published the series of textbook in 2004. The contents of pharmacology are taught just after pathology and pathophysiology in every organ system. In comparison with the traditional teaching mode, teachers of pharmacology need not spend a lot of time to review preceding knowledge of anatomy and histology, physiology, pathophysiology and pathology. This is helpful in saving time and improving the teaching efficiency.

Evaluation of modified hemodilution combined therapy in the treatment of acute ischemic stroke in the elderly

BACKGROUND: Thrombolysis therapy is not suitable for the elderly patients with acute ischemic stroke who delayed to be diagnosed for more than 3 hours, but traditional medicine is also not very ideal.OBJECTIVE: To observe the clinical therapeutic effect of modified hemodilution combined therapy applied in elderly patients with acute cerebral thrombosis and analyze the mechanism of this therapeutic method.DESIGN: 1:1 paired grouping according to gender and controlled observation.SETTING: Department of Internal Medicine, Chengzhanyuan District, First Hospital Affiliated to Zhejiang University.PARTICIPANTS Totally 90 elderly patients with acute ischemic stroke who received the treatment in the Cadre Ward and Mental Ward, Department of Internal Medicine, Chengzhanyuan District, First Hospital Affiliated to Zhejiang University from March 1996 to June 2004 were recruited. They all met the diagnosis criteria revised by the Fourth Academic Conference of National Cerebrovascular Diseases in 1995 and were diagnosed as acute ischemic stroke by skull CT. They were informed of therapeutic plan and detected items.According to 1:1 paired principle in gender, 90 enrolled patients were assigned into treated group (n=45)and control group (n=45). There were 39 male and 6 female in the treatment group, and they were aged (76±6)years, ranging from 71 to 84 years, and hospitalized at the 14th to 76th hours after onset. There were 39 male and 6 female in the control group, and they were aged (76±6)years , ranging from 70 to 82years, and hospitalized at the 16th to 72th hours after onset.METHODS: Therapeutic method: Patients of treated group received modified hemodilution combined therapy.200 mL whole blood of patients was exchanged with 500 mL dextran-40 (including 20 mL danshen parenteral solution and 32 mg heparin) at the beginning of therapy; From the 2nd day, compound huangqi tea bag (Huangqi mainly, including danshen, honghua, chuanxiong, shishao and a little acetyl salicylic acid) was made, twice a day, 1 bag once. At the same time, the above-mentioned dextran-40 liquid of 500 mL was intravenously injected, once a day, 14 days in total; On the 6th day after therapy, the above-mentioned aseptic autoblood stored in refrigerator at 4 ℃ was transfused back into the patients following pre-treatment of high-concentration oxygenation and ultraviolet irradiation by light quantum instrument.

GENERAL SURGERY——Breast The effect of HO-1 activated via P38α pathway in the genesis and chemotherapy resistance of breast carcinoma

Objective To investigate the role of p38a pathway and HO-1 in the genesis and chemotherapy resistance of breast cancer. Methods The proliferation and apoptosis of human breast cancer cells were examined by MTT assay. The expression of p38a and HO-1 mRNA were examined by RT-PCR. Results The p38a mRNA level in 78 % of samples was significantly greater than that in the normal tissue and the p38a mRNA level in patients with lymph node metastasis was higher than that without lymph node metastasis （P 〈 0.01 ）. The HO-1 activated with 5 μmol/L pirarubicin increased more in MCF-7/adr cells than in MCF-7 cells, and was completely blocked by p38a inhibitor in MCF-7/ADR but only partially in the MCF-7 cell line.
