Objective To study plasma tumor necrosis factor ?(TNF ?) level and its relationship with insulin resistance in familial type 2 DM. Methods Plasma TNF ? were determined by RIA in 32 familial type 2 DM patients, their 37 non diabetic first degree relatives and 40 healthy control subjects. Results Plasma TNF ? was significantly higher in familial type 2 DM patients[(1.19?0.21)?g/L] than in healthy control subjects[(1.00?0.18)?g/L]( P 0.05). Regression analysis indicated that TNF ? was inversely related to ISI and was a significantly independent contributor to variations in ISI. 39% of the variance in ISI was explained by TC, body mass index(BMI)and TNF ?. Conclusion The finding of an association between high plasma levels of TNF ? and insulin resistance suggests that TNF ? may be involved in the pathophysiology of insulin resistance in familial type 2 DM patients.

OBJECTIVE:To explore loading dose simvastatin on related indicators in PCI perioperative period of patients with acute myocardial infarction. METHODS:Data of 203 acute myocardial infarction patients undergoing emergency PCI were retro-spectively collected and divided into observation group (102 cases) and control group (101 cases) by different regimens. Control group received conventional treatment for 3 d before PCI,including orally taking Aspirin enteric-coated tablet 300 mg/d,qd + Sim-vastatin tablet 40 mg/d,qd,simvastatin 40 mg/d after surgery,qd,for 4 weeks. Observation group received Simvastatin tablet 80mg 2 h before PCI,the other treatment was the same with control group. Total cholesterol(TC),triglyceride(TG),low-density li-poprotein cholesterol (LDL-C),high-density lipoprotein cholesterol(HDL-C),IL-6,IL-10,TFN-α,plasma super-sensitive tropo-nin(TNT-HSST)level,creatine kinase isoenzyme(CKMB)level,high sensitive C-reactive protein(hs-CRP)level and transami-nase level before and 24 h after treatment were observed and the incidence of adverse reactions was recorded. Meanwhile,the inci-dence of postoperative 30 d of MACE and CIN was followed-up. RESULTS:There was no significant difference in TG,TC, LDL-C,HDL-C before and after treatment(P>0.05). Before treatment,there was no significant difference in TNF-α,IL-6,IL-10, hs-CRP,CKMB,TNT-HSST levels in 2 groups (P>0.05);after treatment,TNF-α,IL-6,hs-CRP,CKMB,TNT-HSST levels were significantly higher than before(P<0.05),and TNF-α,IL-6,hs-CRP levels in observation group was significantly lower than control group,CKMB,TNT-HSST levels were significantly higher than control group;IL-10 was significantly lower than before in 2 groups,and observation group was higher than control group,with statistical significance (P<0.05). The MACE rate and CIN rate in observation were lower than control group with statistical significance(P<0.05). And no obvious adverse reaction was found in 2 groups. CONCLUSIONS:Loading dose simvastatin in PCI perioperative period can significantly reduce patients' PCI, TNF-α,hs-CRP,CKMB,TNT-HSST levels and the incidence of cardiovascular and renal adverse reactions.

Objective:To present evidence for the pathogenetic role of allergic factor,histamine,in type I allergy for induction of liver damage.Methods:Three groups of rabbits were fed normally and injected (iv) daily with 0, 0.04 or 0.08 ?g/kg phosphohistamine, respectively, for days. The serum level of ALT and AST in each group rabbits was assayed dynamically during the treatment. After treatment for days, the tested rabbits were sacrificed for pathological examination of the liver tissues.Results:The serum level of both ALT and AST in rabbits treated with phosphohistamine increased significantly during the tested periods, compared to that of the control group. However, both ALT and AST levels showed no significant difference between 0.04 ?g/kg and 0.08 ?g/kg groups. Liver microscopic examination, pathological damage could be observed in the tested groups in a time-and dose-dependent manner under microscopic examination. No evident pathological change appeared in the control group.Conclusion:Liver damage could be induced by histamine dosage-and time-dependently. This pathological action of histamine, a type I allergic factor, presents further evidence for a direct role of type I allergy in the pathogenesis hepatic injury.

OBJECTIVE:To investigate the effects of simvastatin intensive treatment on the Postoperative Related Indexes of patients with acute coronary syndrome(ACS) underwent percutaneous coronary intervention(PCI). METHODS:106 patients with were included in the study and randomly divided into observation group(53 cases)and control group(53 cases). Both groups were given aspirin 100 mg,qd+clopidogrel 75 mg,qd before PCI for 4 weeks;observation group was additionally given Simvastatin tablet orally 20 mg before supper 15 d before surgery. TC,TG,LDL-C,HDL-C,hs-CRP,IL-6 and IL-18 levels,LVEF,the occurrence of coronary artery restenosis were detected in 2 groups before surgery and 6 months after surgery. The occurrence of ADR was recorded during treatment. RESULTS:There was no statistical significance in the levels of TG,TC,LDL-C and HDL-C between 2 groups before surgery and 6 months after surgery (P>0.05). There was no statistical significance in hs-CRP,IL-18, IL-6 and LVEF levels between 2 groups before surgery(P>0.05). 6 months after surgery,hs-CRP,IL-6,IL-18 and LVEF levels of 2 groups were significantly higher than before treatment;hs-CRP,IL-6 and IL-18 levels of observation group were significantly lower than those of control group,and LVEF was significantly higher than control group,with statistical significance (P<0.05). The incidence of coronary artery restenosis in observation group was significantly lower than control group, with statistical significance (P<0.05). No ADR was found in 2 groups during treatment. CONCLUSIONS:Preoperative simvastatin intensive treatment can effectively reduce cardiovascular inflammation degree in patients with ACS after PCI,prevent the formation of coronary artery thrombus,and reduce the incidence of coronary artery restenosis so as to effectively improve the prognosis and don' t increase the incidence of ADR.

AIM: To explore the relationship between intercellular adhesion molecule-1(ICAM-1)expression in endothelial cells(EC) and advanced glycosylation end products(AGEs) stimulation. METHODS: Murine bone marrow derived ECs was stimulated by AGEs after pretreated with anti-AGEs, anti-IL-1? and N-acetylcysteine(NAC),then SOD activity and ICAM-1 concentration and adhesion rate(AR) were evaluated. RESULTS: ECs which expressed ICAM-1[(0.65?0.14) vs (0.11?0.02)] induced by AGEs showed lower SOD activity [(0.69?0.19)?10 3 U/L vs (1.71?0.42)?10 3 U/L]. The ICAM-1 expression as well as the increase of AR caused by AGEs stimulation could be suppressed by anti-AGEs(0.12?0.01) and NAC(0.11?0.05). Anti-IL-1? had no influence on these changes. CONCLUSION: AGEs could induce endothelial cells to express ICAM-1 in vitro, most probably due to the formation of free radicals. Besides, AGEs may stimulate other cells to secrete cytokines resulting in ICAM-1 expression in endothelial cells.

BACKGROUND: Femoral head necrosis can be induced in adult rabbits when a large dose of steroid has been used for a long time. However, the pathogenesis of steroid-induced femoral head necrosis needs further study.OBJECTIVE: To probe into the mechanism of the disease by light microscope and transmission microscope from morphological perspective based on the model of femoral head necrosis in rabbits.DESIGN: A randomized controlled observation.SETTING: Laboratory of Morphology; Teaching and Research Division of Pathology; Laboratory of Surgery, Weifang Medical College.MATERIALS: The experiment was carried out at the Experimental Center of Morphology, Weifang Medical College, between March 2002 and March 2003. Totally 40 adult New Zealand white rabbits were randomly divided into control group (n=10), dexamethasone group (n=10) and horse serum group (n=20).METHODS: Control group was given intravenous injection of normal saline of 10 mL/(kg·d) for 7 consecutive days. Dexamethasone group was given intramuscular injection of dexamethasone of 10 mL/(kg ·d)for 7consecutive days. Horse serum group was given intravenous administration of horse serum of 10 mL/kg; 3 weeks later the same volume of horse serum was injected once again, followed intramuscular injection of dexamethasone of 10 mL/(kg·d)for 7 consecutive days. Inferior sections of cartilage of the femoral head necrosis in the experimental animals were obtained 5 and 10weeks later, and then histological and ultrastructural changes were observed under the light microscope and transmission microscope.MAIN OUTCOME MEASURES: ① Histo-morphological observation of the animals in each group. ② Ultrastructural changes.RESULTS: All the experimental animals survived and entered the result analysis. ① Histo-morphological observation: The cells of inferior sections of cartilage of the femoral head necrosis of the experimental animals in control group were arranged regularly and had a small volume of elliptical bone cells. The cell body was located at bone lacuna, blood vessel arranged well in the medullary cavity of bone. Lesion haracteristics of femoral head in dexamethasone group and horse serum group were similar:Hematopoietic adipose in the medullary cavity of bone was significantly decreased while fat adipose obviously increased; bone trabecula of metaphysis and the inferior sections of cartilage of femoral head were found with ered, and so was the bone nucleus. The number of lacuna of bone was increased. ② Ultrastructural changes: Normal bone cells in control group were elliptical, located at bone lacuna. Nucleus was at one end of the cell with complete karyotheca and many mitochondria in the cytoplasm. In dexamethasone group and horse serum group there were lipid droplets in the osteocytes, narrowed blood capillary in the medullary cavity of bone and injured vascular endothelial cells.CONCLUSION: Corticotropin can induce necrosis of femoral head; the hormone causes accumulated fat adipose in the medullary cavity of bone.The increased internal pressure in the medullary cavity leads to ischemia of femoral head, thus inducing the necrosis of osteocytes.
