2. Serum profile of Th17-related cytokines in patients with primary biliary cirrhosis
Academic Journal of Second Military Medical University 2010;30(6):703-705
Objective: To observe the serum profile of Th17-related cytokines(IL-1β, IL-6, IL-17A, IL-23, and TGF-β) in patients with primary biliary cirrhosis, so as to study the role of Th17 cells in the pathogenesis of primary biliary cirrhosis (PBC). Methods: Seventy-eight patients with PBC, 30 patients with HBV-related posthepatitic cirrhosis(PHC), and 60 healthy controls (HC) were enrolled in this study. The serum levels of above five Th17-related cytokines were determined by enzyme-linked immunosorbent assay (ELISA). Results: The levels of IL-1β, IL-6, IL-17A, and IL-23 in PBC group were significantly higher than those in HC group (P<0.05); the levels of TGF-β were comparable between the PBC group and HC group. The levels of IL-1β, IL-6, and TGF-β were significantly lower and IL-17 A, IL-23 were significantly higher in the PBC group compared with those in the PHC group (P<0.05). Conclusion: Our findings indicate that PBC patients are in a status of chronic inflammation. Th17 subset may play an important role in the development and progression of PBC.
3. Changes of hepatic caspase-3 and caspase-8 activities during liver regeneration in rats
Academic Journal of Second Military Medical University 2006;27(5):500-502
Objective: To study the changes of hepatic caspase-3 and caspase-8 activities during liver regeneration in rats. Methods: Liver regenerati on model was produced by 70% partial hepatectomy (PH) in male SD rats. Then the rats were sacrificed and the liver homogenate were prepared. Hepatic caspase-3 and caspase-8 activities were determined at 8 different time points during the liver regeneration at the absorbance of 405 nm. Results: Hepatic caspase-3 activity increased significantly 3 h, 6,72 h, 120 h and 168 h after PH compared with that of control group(P<0.001); Hepatic caspase-8 activity increased 168 h after PH(P<0.05) and had no obvious change at any other time points. Conclusion: Our result suggests that the increase of caspase-3 activity during the liver regeneration may be mainly induced by the mitochondrial pathway.
4.DNA image cytometry in breast fine needle aspiration cytology
Cancer Research and Clinic 2012;24(8):521-523
Objective To discuss the diagnosis value of DNA imaging cytometry (DNA-ICM) analysis in fine needle aspiration cytology (FNAC).Methods Conventional cytopathology and DNA-ICM were used to detect 95 fine needle aspiration patients with breast masses.The results were analyzed according to the histopathological diagnosis.Results There was not significant difference between conventional cytopathology and DNA-ICM [88.4 %(84/95) vs.94.7 %(90/95)] (x2 =2.457,P =0.117).Two false positive cases had been found in conventional cytopathologic diagnosis,but not in DNA-ICM.There was a positive correlation between the nucleus area and its DNA content (r =0.744,P =0.000).By DNA-ICM,the detectable rate of abnormal DNA content in the infiltrating ductal carcinoma was higher than that in the infiltrating lobular carcinoma [90.3 %(65/72) vs.50.0 %(4/8)] (P =0.011).Conclusion The detection of DNA-ICM can reduce the false positive rate of FNAC,but it has limitations in diploid tumors.

ObjectiveTo study the reliability to asses s interstitial fibrosis in myocardium of advanced age spontaneous hypertension rats(SHR) by acoustic densitometry. MethodsFifteen 20-month-old spontanous hypertension rats and fifteen age matched Wistar Kyoto(WKY) as control group were included. Ultrasonic backscatter parameters were acquired at interventricular septum, left ventricular posterior wall, left ventricular lateral wall. Normalized values of integrated backscatter of left ventricular lateral wall were compared with results by stereological approach under eletronic and light microscope. Results Compared with control group, SHR group showed different integrated backscatter at interventricular septum, left ventricular posterior wall and left ventricular lateral wall(P

Objective To investigate the relationship between thyroid hormone and uric acid (UA) and body mass index (BMI) in patients with type Ⅱ diabetes and normal thyroid function.Methods Total of 313 patients with type Ⅱ diabetes and normal thyroid function were selected.BMI,fasting blood glucose (FBG),the metabolism of blood lipid,thyroid hormones and UA indicators were examined and the correlations of thyroid hormone,BMI and UA were analyzed.Results (1) The patients were divided into two groups according to gender,and FT3,FT4,and UA of male were found to be significantly higher than those in female (P<0.01).TSH,SBP,HDL-C in female were significantly higher than those in male (P<0.01);(2) The patients were divided into three groups according to BMI Level.Thyroid-stimulating hormone (TSH),three iodine armour gland original glycine (TT3),free three iodine thyroid glycine (FT3),UA,and FBG in overweight and obesity groups were found to be higher than those in normal weight group (P < 0.05);(3) The patients were divided into two groups according to the TSH level.Serum uric acid,TT3,FT3,fasting insulin in the group with TSH above 2.5 uIU/L were found to be higher than those in the group with TSH under 2.5 uIU/L (P < 0.05);(4) Patients were divided into two groups according to the UA level.TSH,FT3 in male with high uric acid were found to be higher than those in male with normal uric acid (P < 0.05);TSH was in female with high uric acid was found to be higher than that in female with normal uric acid (P < 0.05).Conclusion Thyroid hormone in patients with type Ⅱ diabetes can be used to assess the body weight and uric acid,which is of great clinical importance.
