Objective:To construct recombinant expressing vector pcDNA3-DAF and to develop the NIH3T3 cell model expess human complement regulatory protein decay accelerating factor(DAF,CD55)stably after transfected.Methods:Human membrane complement regulatory protein(hCRP) DAF cDNA containing the full-length of encoding region was cloned into expressing vector pcDNA3.After identification by restriction enzyme digestion,PCR and sequencing,the recombinant plasmid was transfected into NIH3T3 cells with calcium phosphate-DNA precipitate method.A stably-transfected cell line was established by G418 selection.Extraneous gene integration was identified by PCR.Expression of DAF at both mRNA and protein levels was analyzed by RT-PCR,Western blot and indirect immunofluorescence microscopy.Results:The eukaryotic expression vector pcDNA3-DAF was successfully constructed and the DAF gene was transfected stably into NIH3T3 cells,a stably-transfected cell line was established and DAF was efficiently expressed on the surface of transfected NIH3T3 cells.Human DAF cDNA was integrated into NIH3T3 pcDNA3-DAF genomic DNA after continuous 30 times passages,indicating that NIH3T3 pcDNA3-DAF was stable cell line.Conclusion:The establishment of the stably-transfected cell line and the expression of the target gene provide a base for further studies on the function of the DAF and the cooperative fashion among different human complement regulatory proteins in alleviating the complement-mediated cytolysis.

ObjectiveTo investigate clinical features,diagnosis and treatment of hyperlipidemic severe acute pancreatitis(HSAP) in late pregnancy. MethodsA retrospective analysis was made on 12 HSAP cases. ResultsHSAP accounting for 20%(12/60) of severe acute pancreatitis (SAP) cases, develops during the period of 28~36 weeks of pregnancy. There were 5 cases in SAP type Ⅰand 7 cases in SAP type Ⅱ. Multiple organ dysfunction syndrome (MODS) was complicated in 4 cases. HSAP is featured with severe hypertriglyceridemia (29?14)mmol/L, significant systemic inflammatory response syndrome (SIRS), large amount of lipidemic bloody ascites. All cases underwent successful. Cesarean section followed by pancreatic operation and were cured. ConclusionHSAP in late pregnancy is a specific type of SAP with fulminant clinical course leading to fetal distress. Effective management of pregnant hypertriglyceridemia helps to prevent HSAP.

Objective To investigate the clinical feature of POEMS syndrome,and raise the level of diagnosis and treat- ment.Methods The clinical data of 2 cases of POEMS syndrome were analyzed and relevant literature were reviewed. Results The clinical manifestation of 2 cases included splenohepatomegalia,splanchnocoel hydrops,endocrine func- tional disorder,nigrescence on face,protein of CSF and IgA and immunoglobulin light chain of serum increasing.The symptoms of 2 patients improved after treatment with hormone and L-Sarcolysinum.Conclusion POEMS syndrome is a rare and complicated disease that can be misdiagnosed.Follow up associated with immunology,endocrine and bone marrow aspiration examination should be carried in time on the patients suspected with POEMS syndrome,which is valu- able to the diagnosis and reducing misdiagnosis and mistreatment.

Objective To evaluate the plasma level of miR-21 in hepatocellular carcinoma (HCC) patients and its clinical diagnostic significance .Methods Case-control study was used .The plasma level of miR-21 was measured by real-time quantitative PCR.The relative expressions of miR-21 were calculated. This study included 60 cases of patients with HCC , 71 patients with liver cirrhosis ( LC ) , 52 healthy volunteers ( HV) from January to June in 2014 in Henan Province People′s Hospital.The receiver operating characteristic ( ROC) curves were analyzed to determine the sensitivity and specificity of miR-21 expression levels in HCC diagnosis. Differences between groups were assessed by the t-test.Results Plasma microRNA-21 level in the 60 patients with hepatocellular carcinoma ( 2.6 ±1.1 ) was significantly higher than in patients with chronic hepatitis (1.6 ±0.9) and healthy volunteers (1.0 ±0.6) (t=5.322,P=0.004;t =8.349, P =0.000 3, respectively ) .Plasma microRNA-21 level in the HCC patients were positively correlated with tumor size and differentiation (tdif=3.366,P=0.019;tsize =3.490,P=0.012). ROC analysis of plasma microRNA-21 yielded an AUC of 0.796 with 70.0% sensitivity and 65.3%specificity when differentiating hepatocellular carcinoma from chronic hepatitis , and an AUC of 0.934 with 89.5% sensitivity and 81.8% specificity when differentiating hepatocellular carcinoma from healthy volunteers.Conclusion The plasma level of miR-21 in HCC patients has high specificity , and maybe help to diagnose of HCC.

To investigate the relationship between the expression of death associated protein kinase (DAPK) gene and oral squamous cell carcinoma (OSCC). The expression of DAPK gene in OSCC was detected by semi-quantitive RT-PCR. The results showed that the expression of DAPK gene was down regulated significantly, which may relate to the tumorigenesis and development of OSCC. The detection of DAPK gene may act as an index in OSCC dignosis.

ObjectiveTo explore the relationship between chronic kidney disease (CKD) and cerebral small vessel disease (SVD) in elderly patients. MethodsOne hundred and fifty-two elderly male CKD patients for experimental group and 158 elderly male for control group were recruited. Demographic data and vascular risk factors were recorded. White matter lesion (WML) was semi-quantitatively assessed by cerebral magnetic resonance imaging (MRI), and lacunar infarction (LI) was also calculated. Results(1) The prevalenees of hypertentsion and diabetes mellitus were higher in elderly CKD patients than those in control group (30. 9% vs. 19.0%, 23.7%vs. 14.6%;both P~0. 05). (2) The percentages of grade 2 and grade 3 WMLs were higher in elderly CKD patients than those in control group (34.9% vs. 24.1%, 25.7% vs. 16.5%;both P<0.05). Prevalence of LI was higher in elderly CKD patients than that in control group (45.4% vs.25.3% ,X2= 13. 70, P<0. 05). The similar Resultswere also obtained except for control subjects with hypertension and diabetes mellitus. (3) The logistic regression analysis showed that age, hypertension and low glomerular filtration rate (GFR) were closely associated with SVD in elderly CKD patients. ConclusionsHypertention and diabetes mellitus are risk factors for CKD in elderly patients. SVD is associated with CKD, and age, hypertension and low GFR may be risk factors for SVD in elderly CKD patients.
