Objective To investigate the relationship between insulin level and mild cognitive impairment(MCI) of type 2 diabetes and analyze the risk factors for MCI. Methods We collected 101 type 2 diabetes subjects who were divided into two groups:MCI and normal cognition(NC).All subjects were evaluated with cognition scores of MMSE,GDS,CMS,ADL.Insulin,glycosylated hemoglobin,blood routine test,blood pressure,ECG,brain CT were detected.Independent t-test,correlation and multiple regression analysis were performed. Results 1. The diabetic patients with MCI showed the higher levels of insulin at fasting, 2hr and 3hr after meal than did NC(P

Objective To assess the clinical application value of magnetic susceptibility-weighted imaging in cerebral vascular malformations. Methods Thirty-six patients with cerebral vascular malformations were enrolled in the study. All the patients received examination of T1WI, T2WI and SWI. SWI sequence was compared with T1WI, T2WI sequence in detecting and diagnosing cerebral vascular malformations. Results Cerebral vascular malformations were low signal in SWI sequence. Cavernous angioma, developmental venous anomalies and AVM had been found in 73,8,10 cases, respectively. The bounder of lesions was clearer, more multiple small lesions, more hair-thin pulp veins and draining veins were detected in SWI sequence. Conclusion SWI sequence has more sensitivity than T1WI and T2WI sequence in detecting the cerebral-vascular malformations. SWI sequence may become routine examination se- quence in diagnosis cerebral-vascular malformations.

Objective To investigate the correlation between caspase-3 and left ventricular function at different phases after ischemia-reperfusion. Methods Totally 36 wistar rats were randomly divided into Sham operation group and ischemia-reperfusion(IR)group. The rat ischemic cardiac region of IR group was taken after 1, 3, 6, 12 and 24-hour reperfusion followed to 30-minute ischemia and detected for the activity fragment of caspase-3 P20, the activity of caspase-3, myocardial apoptosis index, left ventricular function (LVF) and creatine kinase-MB (CK-MB) respectively. Results With reperfusion time prolonging, the activity fragment of caspase-3 P20 increased, the activity of caspase-3, myocardial apoptosis index, left ventricular function and CK-MB all changed. The activity fragment of caspase-3 P20 and CK-MB peaked at 6 h, and the activity of caspase-3 and myocardial apoptosis index at 12 h, and then maintained platform; LVSP and ?dp/dt_max increased while LVEDP decreased gradually with the reperfusion time prolonging. All indexes mentioned above of IR group had statistical significance as compared with that of Sham operation group(P

Polyactin B (Pb) has been proved to have the effect of considerable tumor suppression. Recently,we used murine S_(180) Sarcoma as a model and observed the effect of Pb on the tumor—infiltrating immunocompetent cells, and also the infiltrating neutrophils and the alteration of small blood vessels within the tumor tissue. Compared with control: in Pb—treated group, there were more L_3T_4~+and Lyt_2~+ lymphocytes infiltrating in the periphery of the tumor ,and also within the tumor. In addition, the tumors had more prominant hyperemia, micro—thrombosis and neutrophil infiltration around the necrotic areas. The present findings suggest that the tumor—suppression effect of Pb might be mediated through TNF produced by immunocompetent cells.

Objective To investigate the diagnosis and treatment of Hydatidosis of post-peritoneum and bladder.Methods Nine cases were reported. Among them,one was epinephros-hydatid cyst,two renal hydated cyst,two hydatidosis of post-peritoneum in ileopelvic, and four bladder hydrated cyst. All cases had history of contacting with dog or sheep.Results All of the nine cases were cured by operation. Conclusions In percussion of the lower abdominal mass, hydrated cyst vibration, a specific sign, can usually be felt; and the mass do not disappear after urination. Besides, E-immune Test for echinococcus, B-ultrasonography, and CT are very useful diagnostic methods. Therefore, excision of the cyst still is the only effective treatment for hydatidosis.

Objective:To study the effect of articulation disorder on psychology action of cleft palate patients after operation.Methods:65 patients were asked to answer the psychology questionnaire.Results:The patients of misarticulation all have some degree of psychological disability,and unusual psychology action would affect pronunciation treatment.Conclusion:Patients with misarticulation have psychology problems in some degree,which would affect the clinic treatment of cleft palate.

Objective To understand the microorganism pollution in the indoor air in the campus of Liaocheng University. Methods In April and May, 2004, the content of airborne microbes in the indoor air in Liaocheng University campus was determined by the gravity plate method. Results The average content of bacteria in the indoor air was 2.39?103 cfu/m3, the average content of mildew was 0.62?103 cfu/m3. The predominant microorganism in the internet bars in the campus was bacteria. Conclusion In general, the indoor air quality in Liaocheng University campus is at comparative clear level.
