Objective To investigate clinical significance and related factors of fluid-attenuated inversion recov?ery vascular hyperintensities (FVH) in transient ischemic attack (TIA) of carotid system. Method Data including general information and TIA risk factors was continuously collected from 142 patients with carotid system TIA from the depart?ment of neurology of Sheng jing Hospital affiliated China Medical University from January 2012 to February 2014.All pa?tients completed brain MRI including FLAIR and diffusion-weighted imaging (DWI)and MRA examinations within 72 hours after TIA. All patients were followed up for one month. Risk factors and FVH situations were analyzed based on clinical manifestations and DWI results. Result There were 87 male cases (61.27%)and FVH positive 57 cases (40.14%) among 142 cases with carotid system TIA (mean age 63.2±11.5). Logistic regression analysis revealed that the large intra?cranial carotid artery stenosis≥50%(OR=2.44,95%CI:1.09~5.49, P=0.03) and prior history of ischemic stroke (OR=3.88,95%CI:1.04~14.5, P=0.04) were independently associated with positive FVH. At one month followed-up, 40 cas?es (28.17%) of 142 patients progressed to acute cerebral infarction. Vulnerable plaque number in the contralateral carot?id artery (P=0.018), contralateral intracranial large vessel stenosis in MRA≥50%(P=0.007) and contralateral FVH oc?currence rate (P=0.001) were significantly higher in cerebral infarction group than in non-cerebral infarction group. Con?clusion FVH is common in carotid TIA patients, which is associated with intracranial carotid artery stenosis ischemic and previous history of ischemic stroke. Vulnerable plaque number of contralateral carotid artery, contralateral intracranial large vessel stenosis≥50%and the rate of occurrence of contralateral FVH may be associated with short-term progress leading TIA to acute infarction.

Objective To investigate the value of thorough uterine curettage in microwave endometrial ablation(MEA).Methods Preoperative uterine curettage was conducted in 126 women with abnormal uterine bleeding(AUB)scheduled for MEA from June 2001 to June 2005.At the same period,another 12 patients with AUB underwent hysterectomy.And before the operation,uterine curettage and subsequent MEA were conducted.Then the uterine specimens were histopathologically and histochemically examined for evaluating the tissue damages.Results No intraoperative complications occurred in the 126 patients.Postoperatively,amenorrhea was observed in 78 patients(61.9%),normal menstruation was achieved in 46 patients(36.5%),and small amount of irregular vaginal bleeding was found in 2 patients(1.6%),the overall satisfaction rate being 98.4%(124/126).Postoperative complications included endometritis in 10 patients,hematometra in 2 patients,and dysmenorrhoea leading to hysterectomy in 2 patients.Follow-up observations were conducted for 6～28 months(22?4 months)in 126 patients,116 of whom were followed for more than 2 years.Follow-up findings showed satisfactory surgical effects.After MEA,the injury depth was 4.2～4.9 mm in the uterine fundus,4.1～5.7 mm in the anterior wall,4.7～6.6 mm in the posterior wall,and 4.0～4.7 mm in the uterine horn.Conclusions MEA with preoperative thorough uterine curettage can completely destruct the endometrium.The method offers good efficacy,high satisfactory rate,and low risk of tissue injury.

BACKGROUND:Metabolic syndrome greatly harms the human body, and is affected by many factors. Through constructing diet-induced animal models, we can better analyze the relationship between nutritional factor and metabolic syndrome, and provide reliable references for the clinical treatment of this disorder. OBJECTIVE:To construct obese mouse models with high-fat diet feeding and discuss the relationship between nutritional factor and metabolic syndrome. METHODS:Thirty mice were selected and randomly divided into model group (n=20) and control group (n=10), and were fed with high-fat and normal animal feeds for 10 consecutive weeks. RESULTS AND CONCLUSION:Compared with the control group, after 1 week of feeding with high-fat animal feeds, body weight of mice in the model group raised, and differences gradualy increased with the feeding time increased. After 8 weeks of feeding, body mass index of mice in the model group significantly raised (P < 0.05). After 4 weeks of feeding, fasting venous blood glucose level of mice in the model group significantly raised, and showed a gradual rise trend with feeding time. After 5 weeks of feeding, fasting insulin level of mice in the model group also began to rise. The oral glucose tolerance test showed that mice in the model group showed a gradual downward trend of glucose tolerance with feeding time. After 8 weeks of feeding, serum levels of total cholesterol and high density lipoprotein cholesterol in the model group significantly raised (P < 0.05). After 10 weeks of feeding, serum levels of triacylglycerol, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol in the model group raised (P< 0.05). The results demonstrate that obese mouse models were successfuly constructed with high-fat diet feeding, which can simulate the natural progression of metabolic syndrome in human, moreover, the nutritional factor is closely related to metabolic syndrome.

Objective To explore the impact of advanced glycation end-products ( AGEs) on matrix metalloproteinase 2 ( MMP-2) expression in cultivated INS-1 cells. Method INS-1 cells were cultivated and MMP-2 expression was analyzed. Glycated serum was prepared for incubating with INS-1 cell. Reactive oxygen species (ROS) was detected by flow cytometry. The intracelluar MMP-2 expression was analyzed by RT-PCR, realtime PCR and Western blot. The MMP-2 cDNA was expressed in cultivated INS-1 cells. Result The level of ROS treated with AGEs was significantly higher than that in the control( P<0.05 ) , and the levels of MMP-2 and its protein expressions turned out as well( P<0. 05). Conclusion The results suggest that MMP-2 was expressed in INS-1 cells. Increased MMP-2 expression in ?cells may be induced by AGEs, suggesting that MMP-2 might play an important role in oxidative stress-mediated islet injury.

Objective To study the expression and signficance of the osteopontin (OPN) in epithelial ovarian cancer tissue and serum. Methods Immunohistochemistry method and ELISA were used to detect the expression of OPN in 64 cases of epithelial ovarian cancer tissue and serum, 20 cases of ovarian benign tumors and 10 cases of ovarian nomal tissues. Results The OPN expression was associated with the clinical staging and histological grading of epithelial ovarian cancer tissue and serum (P < 0.01). The level of OPN in epithelial ovarian cancer tissue was significantly higher than that in benign ovarian tumor and normal control groups (P < 0.01). Conclusion OPN is remarkably correlated with the carcinogenesis and the development of epithelial ovarian cancer.
