The serum lipid. glucose and insulin levels, daily urine protein, glomerular filtration rate,body weight index and eyeground were also studied. The results showed that 56 patients had obvious myocardial ischemia (group A),49 patients had slight myocardial ischemia (group B)and 395 patients were free from myocardial ischemia (group C). With positive 59MTc-MIBI ECT myocardiography, 15 among 16 patients in group A and 6 among 12 patients in group B and none among 5 in group C showed coronary artery narrowing in coronary radiography. The average course of DM,serum total cholesterol,fasting serum glucose and insulin, glucosylated hemoglobin.daily urine protein and the incidence of proliferative retinopathy of group A were higher than those of group B or C(P

Objective To study the effect of individual and environmental factors of diabeties on their glycemic and lipidic metabolism. Methods While educating diabeties with diabetic informations, we inguired their individual data questionnaires. According to their diabetic periods,cultural levels,compliance to their doctors,daily work times and ocupations respectively,we grouped these patients and compared their fasting and postprandial glycemia (FBG & PBG), GHb,serum lipids and serum uric acid (BUA). Results Among 2 856 diabetic patients,the type I was about 4. 9% and the type Ⅱ about 95. 1% ; the family patients was about 9. 91% and the overweight about 44. 29K. According to patients' compliance to their doctors,blood glucose,GHb and lipids and BUA was lower in absolute compliance group than the basical group or the non compliance one (P＜0. 02),and the levels of glycemia and GHb and TG all related to their compliance (respectively r=- 0. 059, - 0. 055, - 0. 075, - 0. 063 ; and P＜0. 05, 0. 05, 0. 01, 0. 025 ). Considering the diabetes periods,the 1-5 year metabolic control of group was best (P＜0. 02) and the 5- 10 year and above 10 year metabolic control groups were better than the group within one year (P ＜0. 05). To patients' cultural levels, the metabolic control senior or higher middle school groups was better than the junior middle school or lower (P＜0. 05). Thinking their daily work time and occupation,the metabolic control of groups working more than seven hours was worst (p respectively less than 0. 05 and 0. 02). Conclusion diabetic patients' individual and environmental factors are all affecting their metabolic control,among them the complicance is most effective.

Objective To develop a set of hospital material management information system with the mature technique of barcode so as to realize the whole flow management of material.Methods By analyzing the main problems in present hospital material management,we put forward ways and procedures of material management,and gave an overall introduction to the composition of the system from three aspects: warehouse management on material and drugs,the second level storehouse management,such as material management in department,inspect reagent consumptive material management,no stock for high-cost medical consumables management,etc and the cost accounting and collecting system.The key technologies and implementation methods adopted in the designing process of this system were also introduced.Results The achievement of whole flow tracking management from material purchase to material consumption not only ensures a real whole flow management of materials,but effectively reduces the consumption of hospital materials.Conclusion With the mature and advanced technique of barcode and wireless network,the management of material can be better achieved.

Objective To observe the morphologic changes of of vascular buds in vertebral cartilage endplate in age-specific rabbits and also to investigate the correlation between the changes of vascular buds and interverbral disc degeneration. Methods There were 15 New Zealand white rabbits in our study,which include three groups, 2-week-old rabbits, 1-year-old rabbits and 3-year-old rabbits, and each groups had five rabbits. The X-ray radiograph, histology and scanning electron microscope were used to observe the changes of vertebral cartilage endplate. According to Miyamoto standard, the interverbral disc was graded 1-5, and scored 1-5 respectively. Results The changes of micro-vascular structure of vertebral cartilage endplate were observed during aging. Under the scanning electron microscope, the vascular structure degenerated gradually, and disappeared in the end. The blood vessels in the central region of the vertebral cartilage endplate reduced more obviously than those in periphery region. The severe degeneration was found in vertebral endplate, compared with intervertebral disc. The changes of vascular buds in rabbits vertebral cartilage endplate had positive correlation with the vertebral endplate calcification and the interbertebral disc degeneration. Conclusion Changes of vascular buds in vertebral endplate may accelerate intervertebral disc degeneration.

Objective To investigate the combined detection and clinical significance of autoantibodies in patients with autoimmune hepatitis (AIH).Methods Collected 1 593 cases of patients with hepatic dysfunction,33 cases were diagnosed as AIH.Serum anti-smooth muscle antibody (ASMA),soluble liver antigen/liver pancreas (SLA/LP) antibody,liver kidney microsomal-1 (LKM-1) antibody,hepatic cell solute antigen type-1 (LC-1) antibody,anti-mitochondrial antibody (AMA),antinuclear envelope glycoprotein (gp) 210 antibody,anti sp100 antibody,antinuclear antibody(ANA),anti extractable nuclear antigen antibody spectrum (ENA) and anti neutrophil cytoplasmic antibody (ANCA) were measured in patients.The clinical manifestations were recorded.Results In 33 patients with AIH,the positive rate of ANA was 81.8％(27/33).For the diagnosis of AIH,the sensitivity/specificity rate of ASMA were 57.6％(19/33)/97.6％(161/165).The sensitivity/specificity rate of LKM-1 antibody were 12.1％(4/33) /91.5％(151/165).The sensitivity/specificity rate of SLA/LP antibody were 6.1％(2/33)/99.4％(164/165).The sensitivity/specificity rate of anti LC-1 antibody were 9.1％ (3/33)/99.4％ (164/165).There were no antisp100 antibody and anti-gp210 antibody in AIH.Conclusion The diagnostic rate of AIH is improved by combined detection of autoantibodies.

Objective To investigate whether emergency rooms in major general public hospitals are reasonably designed and convenient for patients. Methods 78 major public hospitals were selected from all over China, except Hong Kong, Macau and Taiwan, for emergency room convenience analysis. The standards in use were the "Standards of Hospitals" of Joint commission International Accreditation. Results The investigation found in such hospitals the following: poor road conditions outside the clinic and insufficient guides in the clinic; long-than-expected distance (normally over 50 meters) from ER to imaging departments (such as X-ray and CT scan service); ERs in provincial capital cities are significantly more convenient than those in non-capital cities; distance from ERs to CT service is significantly shorter in hospitals in eastern China than those middle and western China. Conclusions Parameters on ER's service quality from "Standards of Hospitals" could serve as a guideline to emergency medicine in China. ERs in China need to improve with conspicuous ER signs, unblocked passageways, and convenient access to inspection departments.

Purpose: To study new treatment of leukemia with both bcr-abl and mdrl positive. Methods: We detected the effect of STI571 ( 1 ?mol/L), an inhibitor of tyrosine kinase, in combination respectively with vincristine (VCR), daunorubicin (DNR), homoharringtonin( HHT) ( 10-4,10-5, 10-6, 10-7,10-8 mol/L) and DNR + arabinoside cytosine (Ara-C) of 1 mmol/L on a high tumorigenicity in nude mice multi drug-resistant leukemia cell line ( K562-n/VCR) by MTT method. Results: IC50 of VCR and VCR + STI571 were 127.28 ?mol/L, 1. 37 ?mol/L respectively, and synergistic interaction on K562-n/VCR cells was 93. 04-fold. IC50 of DNR and DNR + STI571 were 6. 96?mol/L, 0. 30?mol/L respectively, synergistic interaction was 23. 35-fold. IC50 of HHT and HHT + STI571 were 156.70?mol/L, 7.916?mol/L respectively, synergistic interaction was 19. 80-fold. IC50 of DNR + Ara-C and DNR + Ara-C + STI571 were 0. 10 ?mol/L, 0. 015 ?mol/L respectively, the synergistic interaction was 464-fold. Chemotheraputic agents have not intensive cytotoxic effect on K562-n/VCR cells, but the cytotoxic effect became greater when combined with STI571. Conclusions: Combination of STI571 with DNR, VCR, HHT and DNR + Ara-C had a greater synergistic inhibiting effect on K562-n/ VCR cells . The combinations of STI571 and these Chemotheraputic agents would display synergistic activity in bcr-abl and mdrl positive leukemia cells.
