Objective　To evaluate the value of gradient-echo chemical shift imaging in detection of lipid-containing abdominal lesions. Methods　35 patients with abdominal lesions were divided into 2 groups according to whether or not they contained lipid. Breath-hold in-phase(IP) and opposed-phase(OP) acquisitions were performed. The demonstration of these lesions on IP and OP was compared. The signal intensity of these lesions on both images was measured. The percentage of signal intensity variation on IP and OP was calculated and statistically analyzed with non-parametric method between the 2 groups. Results　For lesions containing lipid, the signal intensity dropped significantly from IP to OP, with median value of signal intensity variation attaining 37.1%. On the other hand, for lesions not containing lipid, the signal intensity did not change obviously between IP and OP, whose median value of signal intensity variation was 3.3%. The difference between the 2 groups was statistically significant (u=4.56，P<0.01). Conclusion　Gradient-echo chemical shift imaging is an easy and practical way, helpful to detection of lipid component within abdominal lesions.

Over the past ten years studies in animals and human have supported the links between inflammation and tumors. The inflammatory cells and agents found in tumors play an important role in the pathogenesis of malignant disease facilitating tumor growth, invasion and metastasis. This article reviewed the molecular mechanism of inflammatory action in promoting tumors and suggested that inflammatory cytokine network is more likely to contribute to immunosuppression than to mount an effective host anti-tumor response.

Objective To explore the diagnosis, surgical treatment and prognosis of thymoma complicated with myasthenia gravis(MG). Methods A retrospective analysis was performed in 33 thymoma patients with MG, who underwent surgical treatment. Results The total effective rate of operation was 75.8%, and the 5 and 10 years survival rates of the patients after operation were 85% and 78.7%, respectively. According to the Masaoka staging system, the 5 and 10 years survival rates of stages I and II were obviously higher than those of stages III and IV (P

Objective To study the positive incidence and clinical significance of auto-antibody of liver antigens in the serum of patients with autoimmune hepatitis diseases and viral hepatitis.Methods The serum samples with hepatic diseases were col-lected in Jiangyin People’s Hospital from 2010 to 2014 year.Patients were divided into three groups according to diseases:autoimmune hepatic disease group including autoimmune hepatitis (AIH)12 cases and primary biliary cirrhosis (PBC)36 case;viral hepatic group including HAV 23 cases,HBV 30 cases,HCV 14 cases and HEV 8 cases;normal control group 30 cases.Auto-antibody of live antigens AMA-M2,LKM-1,LC-1,SLA/LP,GP210 and SP100 were tested respectively by west-ern blotting assay.Results The positive rates of anti-AMA-M2,anti-LKM-1,anti-LC-1,anti-SLA/LP,anti-GP210,anti-SP100 were 16.7%,16.7%,8.3%,25%,0% and 16% respectively in AIH group,83.3%,0%,0%,0%,44.4% and 27.8% respectively in PBC group.Patients with viral hepatitis,one case were anti-AMA-M2 positive,one case were anti-GP210 positive and three case with positive anti-SP100.anti-AMA-M2,anti-GP210 and anti-SP100 were detected more fre-quently in autoimmune liver diseases group than viral hepatitis group (χ2 = 33.9,10.6 and 8.8,P < 0.05),anti-SLA/LP were detected more frequently in AIH group than PBC group (χ2 = 6.4,P <0.05),while anti-AMA-M2,anti-GP210 and were detected more frequently in PBC group than AIH group (χ2 =15.1 and 6.1,P <0.05).The positive rate of viral hepat-ic group was a very low frequency,there are little statistically significant difference (χ2 =1.1,P >0.05)compared with nor-mal control group.Conclusion The antibody of liver antigens are useful clinically for diagnosing and classifying autoimmune liver disease.

Objective:To investigate the effect of microgroove surfaces of titanium on the adhesion and cell cycle progression of human gingival fibroblasts(HGFs).Methods:Microgroove titanium surfaces were fabricated on silicon plate by photolithography with parallel grooves:1 5,30 and 60 μm in width and 5 μm and 1 0 μm in depth,the groups were denoted as T1 5 /5,T1 5 /1 0,T30 /5,T30 /1 0, T60 /5 and T60 /1 0,respectively.Smooth titanium surfaces (T0)were used as the controls.Surface topography were observed by ES-EM.HGFs were cultured on the microgroove surfaces.Morphology of “contact guidance”was observed by immunofluorescence tech-nique.Cell cycle distribution was analyzed by Flow cytometry.Results:HGFs on the microgroove surfaces had “contact guidance”par-allel to the microgrooves,whereas the cells on T0 were oriented randomly.T60 /1 0 group had the highest percentage of S phase cells, followed by T30 group and T1 5 group,but still higher than that in the control group.In groups with higher groove width (T60 group and T30 group),the increase of groove depth benefited the increase of S phase percentage,while in T1 5 group,the increase of groove width decreased the S phase percentage.Conclusion:Surfaces of microgrooves with different dimensions achieved “contact guidance”for the cultured HGFs.The surfaces with increasing groove width and depth benefit the cell cycle progression.

Objective To investigate neurological recovery effect and mechanisms of blood activating and phlegm removing decoction in the treatment of patients with hypertensive cerebral hemorrhage.Methods 68 patients with hypertensive cerebral hemorrhage in our hospital were divided into two groups.34 patients of the control group were given conventional western medicine,and 34 patients of the observation group were taken conventional western medicine combined with blood activating and phlegm removing decoction.The clinical outcomes, hematoma volume change and neurological recovery were compared,and analyzed its mechanism of action.Results The effective rate of the observation group(94.12%) was significantly higher than 73.53%of the control group (χ2 =5.31,P<0.05). After 7d,14d,21d treatment,NIHSS scores of the observation group [(12.87 ±1.43) points,(8.55 ±1.11) points and (5.67 ±0.76) points] were significantly lower than those of the control group [(20.43 ±2.57) points, (17.66 ±2.08)points,(14.54 ±1.44)points],and the differences were statistically significant (t=14.99,22.53, 31.76,all P<0.05).After treatment,hematoma volume of the observation group[(6.44 ±0.54)mL]was significant-ly lower than before treatment[(16.30 ±1.90)mL]and after treatment in the control group [(12.11 ±1.44)mL] (t=29.11,21.50,all P<0.05).After treatment,ALD score of the observation group [(66.34 ±5.22)points] was significantly lower than before treatment[(27.53 ±2.20)points]and after treatment in the control group[(47.55 ± 3.33)points],and the differences were statistically significant(t=39.95,17.70,all P<0.05).Conclusion The effect of blood activating and phlegm removing decoction in the treatment of patients with hypertensive cerebral hemor-rhage is significant,can significantly improve neurologic impairment and daily living skills,has no obvious conflict of interest and high application value,worthy of promotion and application.

A volunteer was scanned by spiral CT,the Dicom format images were imported into Mimics software to reconstruct 3-D mandibular model,then optimized by Geomagic and meshed in Ansys software. A good geometric precise three-dimensional finite element model was constructed. The displacement of dentition was similar with clin-ical situation by computer.

The effects of hepatocyte growth factor(HGF) on the secretion of vascular endothelial growth factor(VEGF) in cultured bovine coronary artery endothelial cells(BCAEC), bovine coronary artery smooth muscle cells(BCASMC) and mouse cardiomyocytes were observed in vitro . The concentrations of VEGF in BCAEC control and HGF group at 12h were 10.51?2.90pg/ml and 9.31?2.78pg/ml, respectively. The concentrations of VEGF at 12h in BCASMC control and HGF group were 3.35 and 3.93 times of that at 3h respectively, the concentration of VEGF at 3h and 12h in BCASMC HGF group was 2.06 and 2.42 times respectively, of that in control group. The concentrations of VEGF at 12h in cardiomyocyte control and HGF group were 5.43 and 4.09 times, respectively, of that at 3h, and the concentrations of VEGF at 3h and 12h in cardiomyocyte HGF group was 2.74 and 2.06 times, respectively, of that in control group. These results indicated that BCAEC, BCASMC and mouse cardiomyocytes could secrete VEGF, and HGF could promote VEGF secretion in BCASMC and cardiomyocytes, but not in BCAEC.
