Three dimensional contrast enhanced magnetic resonance antiography(3D CEMRA) is an imaging method with the signal produced by shortening the blood relaxation time with gadolinium contrast medium but not with natural blood flow;it is a convenient and practical method with no trauma or radiation.Imaging quality was satisfactory,in which the normal anatomy,lesion site and stenosis of arteries were showed clearly.High quality images of 3D CEMRA mainly depended on the optimal acquisition delay time,proper injection rate,volume of contrast material,reasonable sequence and parameters and operators' skills.3D CEMRA has the similar effect with digital subtraction angiography;it is an effective,fast,comprehensive and reliable technique and is an ideal measurement for diagnosing vascular diseases of extremities.

Objective To investigate the effects of genetic factors on the onset of psoriasis. Methods Seven hundred and twenty patients with psoriasis vulgaris were studied by questionnaire. Results① For the male and female patients, the peak ages of the first onset were 20～ 29 and 10～ 19 years, respectively, and the average ages were 27.57? 12.18 and 23.01? 12.40 years, respectively.② In 720 psoriatics, 212 cases (29.4％ ) reported to have a family history of psoriasis. The age of onset was earlier in man with family history than that in man without family history (P0.05).④ The heritabilities of psoriasis were 71.07％? 2.05％ in first degree relatives and 36.77％? 5.17％ in second degree relatives. Conclusion The results show that psoriasis vulgaris may be a multigenic inheritable disease, and the genetic factors play an important role in the pathogenesis.

Objective To analyze genetic types and clinical features with anhi drotic ectodermal dysplasia (EDA). Methods The genetic types and clinical manife stations of 35 patients with EDA in five families were analyzed by genealogical investigation and clinical examination. Results① All patients were males in fam iliesⅠ ,Ⅱ ,Ⅳ andⅤ . The females in these families were recessive carriers. T herefore, the genetic types were X linked EDA. There were 8 males and 6 female s in familyⅢ . The proportion of males to females approximated to 1∶ 1, indica ting autosomal dominant inheritant EDA.② In families with X linked EDA, Types Ⅰ andⅡ were divided according to clinical manifestations of the families. The patients in familiesⅠ andⅣ belonged to typeⅠ , with the characteristics of sp ecial appearances, such as defects in the development of hair and sweat glands, hypophrenia and bad sights. Intelligence and physical development were lower tha n those of general population. However, the patients in familiesⅡ andⅤ belonge d to typeⅡ . It was characterized by sparse hair, hypohidrosis and inborn teeth less or teeth dysplasia. Intelligence and physical development were the same as general population. In the family with autosomal dominant inheritant EDA, patien ts manifested hypohidrosis only, and had no other characteristics.③ Histopathol ogy showed defects in the development of hair follicles and sweat glands in pati ents with X linked EDA, but dysplasia of sweat glands and congenital defect of hair follicles in patients with autosomal dominant inheritant EDA. Conclusion T here are variations in hereditary types and clinical manifestations of patients with EDA.

Purpose: To evaluate the significance of elective splenectomy for Hodgkin's lymphoma. Materials and Methods: Elective splenectomy, total node irradiation (TNI) and chemotherapy (COPP) were performed in 36 patients with Hodgkin's lymphoma from May, 1979 to June, 1988. Result: Spleen invasion was proved in nine of eleven patients with Stage Ⅲ B MC who had been revealed as positive by or splenomegaly before. In stage Ⅲ B patients who were treated by total node irradiation (TNI), the leucopenia was lower in patients who received splenectomy (n=14) than those of without splenectomy (n=12)(P

Objective:This study aims to investigate the method and clinical outcomes of feeding tube placement and periopera-tive nutritional support for esophageal carcinoma patients. Methods:A total of 513 esophageal carcinoma patients who have undergone radical resection and reconstruction by a single operating group between January 2012 and December 2013 participated this study. Feed-ing tubes were inserted via the nasal path of 497 cases and by jejunostomy in 16 cases. Early enteral nutrition (EN) was administered through the feeding tubes 24 h postoperatively with a stepwise increase, whereas supplementation of parenteral nutrition (PN) was ter-minated until total EN. Results:Feeding tubes were successfully inserted in all patients during operation. No death or nutritional and metabolic disorders were documented during the observation period. No differences in anastomotic fistula, pulmonary complication, and incision infection were identified between the nasointestinal and jejunostomy groups (P>0.05). A higher incidence of intestinal ob-struction was observed in the jejunostomy group than in the nasointestinal group (P<0.05). Conclusion:Effective placement of nasoin-testinal tube and early enteral feeding are safe and effective methods for patients who have undergone esophagectomy for esophageal carcinoma.

Objective:To investigate the effect of the adoptive transfer of CD4+CD25+Foxp3+regulatory T cells ( iTregs) induced by 5-aza-2′-deoxycytidine (5AzaD) on pregnant outcome of the abortion-prone mice.Methods:Sixty cases of female CBA/J × male DBA/2J abortion-prone matings were taken as study group,the CD4+T cells from spleen of twenty female CBA/J mice were separated by magnetic activated cell sorting (MACS),5AzaD was applied to the conversion of CD4+CD25-T cells to iTregs,the expression of Foxp3 in Tregs was characterized by flow cytometry analysis before and after epigenetic modification.The purified iTregs were injected into abortion-prone mice on day 1 or 4 of pregnancy,respectively,which were used as therapy groups,and then the embryo resorption rate was counted on day 14 of pregnancy.Results:After the treatment of 5AzaD,the percentage of iTregs in CD4+T cells was (41.50±8.03)%.The embryonic absorption rates of the two therapy groups were 10.47%(on day 1 of pregnancy) and 21.69%(on day 4 of pregnancy) ,respectively ( P<0.05 ) .Conclusion: Epigenetic modication of CD4+CD25-T cells may solve the problem of nTregs deficiency,particularly adoptive therapy of 5AzaD-induced iTregs at early stage of pregnancy can maintain normal pregnancy.

OBJECTIVETo investigate the level of hypermethylated ras association domain family 1A (RASSF1A) gene in maternal plasma of pre-eclampsia and its clinical value.

METHODSSixty pre-eclampsia women including 30 mild and 30 severe cases were selected, 60 women with normal pregnancy were studied as control. Free DNA from plasma samples was extracted, fluorescence quantitative polymerase chain reaction (FQ-PCR) was used to detect the concentrations of RASSF1A gene before and after methylation-sensitive restriction digestion. Meanwhile, beta-actin gene was detected as a control to confirm complete enzyme digestion.

RESULTSThe median concentration of hypermethylated RASSF1A gene was 3.31-fold higher in samples from pre-eclamptic pregnancies than that in controls. There was significant difference between the mild and severe pre-eclamptic subjects (P<0.05), with the median concentrations of 1659 copies/mL and 2036.50 copies/mL, respectively.

CONCLUSIONHypermethylated RASSF1A gene in pre-eclampsia plasma was significantly increased and the concentrations were related to the severity of pre-eclampsia.

OBJECTIVE: To investigate the potential effect of NALP3 inflammasome on the occurrence and development of nonalcoholic steatohepatitis (NASH). METHODS: THP-1 macrophages were cultured for 24 h by palmitic acid at various concentrations. The THP-1 macrophages were pretreated with N-acetyl-cysteine at different doses for 24 h before the palmitic acid cultivation. ROS production was determined by flow cytometry. The expression of IL- 1β was detected by ELISA; the expressions of NALP3 protein and caspase-1 protein were detected by immunofluorescence; NALP3, ASC, and caspase-1 mRNA were measured by real-time PCR. RESULTS: Compared with the THP-1 macrophages without palmitic acid, the level of ROS, NALP3 protein and caspase-1 protein, and the expression of IL-1β were increased after palmitic acid treatment in a dose dependent manner (P<0.05). Compared with the THP-1 macrophages with palmitic acid (400 μmol/L), the level of NALP3 mRNA (P<0.05), the level of NALP3 protein and caspase-1 protein (P<0.05), the expression of IL-1β (P<0.05) were decreased after preadministration of N-acetyl-cysteine in a dose dependent manner. CONCLUSION ROS induced by free fatty acid can regulate the activation of NALP3 inflammasome signaling pathway leading to the release of inflammatory cytokines. This pathway may be the possible mechanism of NASH.
