BACKGROUND:Previous studies have suggested that the risks for coronary atherosclerotic plaque progression and in-stent restenosis are increased in patients with coronary heart disease combined with type 2 diabetes. OBJECTIVE:To explore the predictive factors for in-stent late loss and non-culprit coronary lesion progression in patients with type 2 diabetes mel itus. METHODS:A total of 399 stenting patients were enrol ed, including 179 diabetic patients and 220 non-diabetic patients. The clinical materials, angiography parameters and biochemical markers were col ected. The difference between the two groups was compared, and also we conducted subgroup analysis in the diabetic patients. Low-density lipoprotein cholesterol, hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein were detected at days 3, 120, 210 and 360 after stenting. RESULTS AND CONCLUSION:Compared with non-diabetic patients, the stent length (P=0.18) was longer and the stent diameter (P=0.002) was smal er in the diabetic patients. The minimal lumen diameters of post-procedure and fol ow-up angiography in the diabetic group were significantly decreased (P=0.001, P=0), and the diabetic patients also showed severe coronary artery stenosis instantly and within the fol ow-up after stenting (P=0.038, P=0.004). The fol ow-up angiography showed that the diabetic patients had more late loss and restenosis (P=0, P=0.097). Furthermore, in the subgroup analysis of diabetic patients, the levels of hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein were significantly increased in the patients with restenosis and non-culprit lesion progression. These findings indicate that diabetic patients appear to have the higher incidence of restenosis and non-culprit lesion progression. Moreover, hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein are effective predictors for in-stent late loss and non-culprit coronary lesion progression.

Objective To evaluate the role of Fas/FasL signaling pathway in ulinastatin postconditioning-induced attenuation of apoptosis in the myocardial cells of patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB).Methods Forty patients of both sexes,aged 21-59 yr,of ASA physical status Ⅱ or Ⅲ (NYHA class Ⅱ or Ⅲ),scheduled for elective cardiac valve replacement with CPB,were randomly divided into 2 groups (n =20 each):control group (group C),and ulinastatin postconditioning group (group U).In group U,ulinastatin 10 000 U/kg was perfused via the aortic root at 4 000-5 000 U·kg-1 ·min-1 starting from 5 min before aortic unclamping.In group C,the equal volume of normal saline was infused instead of ulinastatin.Myocardial specimens were taken from the right auricle at 45 min after aortic unclamping for determination of Fas,Fas ligand (FasL),caspase-8,Bcl-2 and Bax expression and cell apoptosis.The ratio of Bcl-2 expression to/Bax expression (Bcl-2/Bax) and apoptotic index were calculated.Results Fas,FasL,caspase-8 and Bax expression and apoptotic index were significantly lower,and Bcl-2 expression and Bcl-2/Bax were higher in group U than in group C.Conclusion Ulinastatin postconditioning attenuates apoptosis in the myocardial cells through inhibiting Fas/FasL signaling pathway in the patients undergoing cardiac valve replacement with CPB.

Objective To investigate the effects of melatonin on choline acetyltransferase (ChAT) in the hippocampus of rats after isoflurane anesthesia.Methods Sixty male SD rats weighing 390-440 g were randomized into five groups (n =12 each):control group (group C),1％ isoflurane group (group Ⅰ),1％ isoflurane + melatonin group (group IM),2％ isoflurane group (group J) and 2％ isoflurane + melatonin group (group JM).Rats in groups IM and JM received intraperitoneal injection of melatonin (10 mg/kg) for 7 days,and rats in other groups received normal saline.On the 7th day of injection,rats in groups Ⅰ and IM inhaled 1％ isoflurane for 4 hours,and rats in groups J and JM inhaled 2％ isoflurane for 4 hours.One day after anesthesia,all the rats began Morris water maze to assess the learning and memory ability,which was made for continuous 5 days.At the end of probe test,6 rats in each group were randomly selected,blood samples were collected to detect plasma melatonin level,and the hippocampi were removed to evaluate the expression and activity of ChAT.The other rats were sacrificed to perform immunofluorescence to detect ChAT in hippocampal CA1 region and dentate gyrus.Results The plasma melatonin level,and the expression and activity of ChAT were significantly lower in group Ⅰ than in group C (P ＜ 0.01).The escape latency was significantly longer,the probe time was significantly shorter,and the plasma melatonin level and the expression and activity of ChAT were significantly lower in group J than in group C (P ＜ 0.05 or 0.01).The escape latency was significantly shorter,the probe time was significantly longer,and the plasma melatonin level and the expression and activity of ChAT were significantly higher in group IM than in group Ⅰ (P ＜ 0.05 or 0.01).The escape latency was significantly shorter,and the plasma melatonin level and the ChAT activity were significantly higher in group JM than in group J (P＜ 0.05 or 0.01).Conclusion Melatonin can attenuate isoflurane-induced ChAT inhibition and thus improve the cognitive function of rats after isoflurane anesthesia.
