Objective To discuss the effica of central venous catheter drainage in interventional treatment of abdominal surgical complications.Methods The clinical data of 72 cases of abdominal surgical diseases were retrospectively analyzed,the complications included 23 cases of ascites,19 cases of bile leakage,8 cases of pancreatic fistula,7 cases of pancreatic necrosis and 15 cases of abdominal abscess,they all underwent percutaneous central venous catheter drainage under the guidance of ultrasound or CT.Results Central venous catheter was placed in 72 cases successfully in one time,the cathetem were kept for 2 to 37 days,5 discharged cases with catheter underwent regular reexamination in the clinic.3 cases of ascites were replaced for catheter shedding; 17 cases for occlusion recieved catheter irrigation and guidewire dredging;2 cases of pancreatic necrosis and 1 case of peripancreatic abscess were cured by repeated puncture and replacement of large-bore catheter.2 cases of pancreatic necrosis,1 case of pancreatic fistula and 1 case of appendicitis underwent laparotomy finally; 1 case of postcholecystectomy bile leakage underwent endoscopic stent therapy; 1 cases of severe pancreatitis complicated with ARDS was treated in ICU.Conclusion Central venous catheter drainage guided by ultrasound or CT for treatment of abdominal surgical complications was not only safe but also effective,and is worthy of popularization and application.

Objective:To investigate the effect of heavy ion beam on the invasion and metastasis associated gene RhoC expression in tongue squamous cell carcinoma Tca8113 cells. Methods:Real-time PCR and Western-blot were used to detect the expression of RhoC mRNA and RhoC protein respectively after Tca8113 cells were irradiated by heavy ion beams of 12 C6+. Results:The expression levels of RhoC mRNA in the experimental group were lower than that in the control group(P<0. 05) except for the levels at 12 h after 2 Gy and 4 Gy 12 C6+ irradiation. In addition, the expression levels of RhoC protein increased in a dose-dependent manner at 12 h af-ter irradiation, reaching a peak at 4 Gy, and subsequently decreased with the increase of irradiation dose. The expression level of RhoC protein was consistent with that of RhoC mRNA. Conclusion:Heavy ion beam of 12 C6+ may inhibit RhoC gene expression in Tca8113 cells.

Objective To investigate the association between the Adiponectin rs266729 and rs2241766 gene polymorphisms and nonalcoholic fatty liver disease in the Han Chinese population residing in Qingdao. Methods Adiponectin rs266729 and rs2241766 gene polymorphisms were genotyped in patients with NAFLD (n = 336) and healthy controls (n = 280) using polymerase chain reaction (PCR). Serum lipid profiles and adiponectin levels were determined using biochemical methods. Statistical analyses were performed using Pearson Chi square test, logistic regression analysis, t test, linear regression analysis. Results We found a significant association between the Adiponectin rs266729 genotype frequencies and allele frequencies between NAFLD pa-tients and controls (χ2= 9.929, P = 0.007; χ2= 9.809, P = 0.002). After adjustment of confounding factor, the rs266729 G allele was associated with an increased risk of NAFLD compared to the C allele (OR = 1.410, 95%CI: 1.082-1.831, P = 0.008) No significant differences were found in the rs2241766 genotype frequencies and allele frequencies between NAFLD population and the controls (OR = 1.410, 95%CI: 1.082-1.831, P = 0.008). Conclusion The Han Chinese in Qingdao carrying the rs266729 G allele are at increased risk of NAFLD.

Objective To observe the serum cyclophilin A(CyPA)level change in the patients with coronary heart disease (CHD)and to investigate its clinical significance.Methods 64 patients with CHD(CHD group)were divided into three groups ac-cording to the clinical types:stable angina pectoris(SAP)group,unstable angina pectoris(UAP)group and acute myocardial infarc-tion(AMI)group;which were divided into three groups according to the coronary artery lesion range:single vessel lesion group, double vessels lesions group and multi vessels lesions group;while 26 controls with normal coronary arteries were select as the con-trol group.Serum levels of CyPA and matrix metalloproteinase-9 (MMP-9 )were detected by ELISA,and C-reactive protein(CRP) concentration was detected by the immune scattering turbidimetry test.Results The CyPA,MMP-9 and CRP levels in the CHD group were significantly higher than those in the control group(P<0.01);the CyPA and CRP levels in the AMI group and the UAP group were significantly higher than those in the control group and the SAP group(P<0.05),the CyPA and CRP levels had no statistically significant difference between the SAP group and the control group(P>0.05);serum CyPA,MMP-9 and CRP levels in the single vessel lesion group,the double vessels lesion group,multi vessels lesion group were significantly higher than those in the control group(P<0.05),serum CyPA,MMP-9 and CRP levels were elevated with the increase of coronary artery lesion vessels (P<0.05).In the CHD group,serum CyPA with MMP-9 and CRP showed the significantly positive correlation(r=0.772,0.749, P<0.01).Conclusion Serum CyPA level is significantly increased in the patients with CHD,CyPA may have some relationship to CHD and the plaque stability.

The effect of astaxanthin on N(Ω)-nitro-L-arginine methyl ester (L-NAME) induced preeclampsia disease rats was investigated. Thirty pregnant Spraque-Dawley rats were randomly divided into three groups (n = 10): blank group, L-NAME group and astaxanthin group. From day 5 to 20, astaxanthin group rats were treated with astaxanthin (25 mg x kg(-1) x d(-1) x bw(-1)) from pregnancy (day 5). To establish the preeclamptic rat model, L-NAME group and astaxanthin group rats were injected with L-NAME (125 mg x kg(-1) x d(-1) x bw(-1)) from days 10-20 of pregnancy. The blood pressure and urine protein were recorded. Serum of each group was collected and malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide synthase (NOS) activities were analyzed. Pathological changes were observed with HE stain. The expression of NF-κB (nuclear factor kappa B), ROCK II (Rho-associated protein kinase II), HO-1 (heme oxygenase-1) and Caspase 3 were analyzed with immunohistochemistry. L-NAME induced typical preeclampsia symptoms, such as the increased blood pressure, urinary protein, the content of MDA, etc. Astaxanthin significantly reduced the blood pressure (P < 0.01), the content of MDA (P < 0.05), and increased the activity of SOD (P < 0.05) of preeclampsia rats. The urinary protein, NO, and NOS were also decreased. HE stain revealed that after treated with astaxanthin, the thickness of basilal membrane was improved and the content of trophoblast cells and spiral arteries was reduced. Immunohistochemistry results revealed that the expressions of NF-κB, ROCK II and Caspase 3 in placenta tissue were effectively decreased, and HO-1 was increased. Results indicated that astaxanthin can improve the preeclampsia symptoms by effectively reducing the oxidative stress and inflammatory damages of preeclampsia. It revealed that astaxanthin may be benefit for prevention and treatment of preeclampsia disease.
