The reconstructed MR angiography was performed using maximum intensity projection (MIP) and multiplanar reconstruction (MPR) techniques. It was found that the chest radiography showed pulmonary sequestration as a persistent area of opacity in the posterior basal segment of the left lower lobe, which was close to mediastinum in 2 cases and close to diaphragma in 3 cases. CT revealed a soft issue mass beyond descending aorta and lobar emphysema around the pulmonary sequestration. And the supplying vessel was documented in 2 cases on enhanced CT. MRI demonstrated a hyperintensity mass with respect to normal lung parenchyma on T1WI and T2WI, and the origin of the supplying vessel in 3 cases. The reconstructed CE MRA using MIP or MRP techniques clearly showed the supplying vessel and its course, branches as well as draining vessels. It was concluded that 3D CE MRA of demonstrating the supplying and draining vessels to pulmonary sequestration, together with plain MRI, can provide a diagnosis and aid in surgical planning without the need for DSA.","PeriodicalId":73995,"journal":{"name":"Journal of Tongji Medical University = Tong ji yi ke da xue xue bao","volume":"21 4","pages":"345-8"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22206414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight cases underwent the operation under cardiopulmonary bypass and 7 of whom under no cardiac clamp. Seven cases received cavopulmonary anastomosis by flaring method and one case by end-side anastomosis. All the patients underwent the intracardiac tunnels to drain inferior vena cava and plus 4 mm fenestration except one. The results showed that 6 patients had postoperative oxygen saturation more than 90%, sinus rhythm, no anastomostic stoma obstruction, no flow regurgitation and CVP < 16 cmH2O. Two (25%) patients died postoperatively from high venous pressure of 18-20 cmH2O, finally from cardiac failure and anoxima. It was concluded that TCPC was an effective treatment for complex congenital cardiac diseases, especially with ventricular maldevelopment. Intracardiac tunnel plus 4 mm fenestration and flaring cavopulmonary anastomosis could prevent the postoperative complications. Larger anastomotic stoma, venous pressure less than 16 cmH2O and artery saturation more than 90% might indicate excellent TCPC procedures in our experience.","PeriodicalId":73995,"journal":{"name":"Journal of Tongji Medical University = Tong ji yi ke da xue xue bao","volume":"21 2","pages":"149-51"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9663509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The BMT group was given normal saline (0.2 ml, twice a day) through gastric tube, while the Ligustrazine group was given Ligustrazine through gastric tube (0.2 ml, twice a day). At the 1st, 7th and 14th day after BMT, we observed the peripheral blood cells and bone marrow nuclear cells (BMNC), as well as the expression level of Heparan Sulfate (HS) and stromal cell derived factor-1 (SDF-1) on bone marrow sections by using immunohistochemistry (SABC-AP), the expression of CXCR4 on the BMNC. The results showed that on the 7th and 14th day, the peripheral blood white cells, platelets, BMNC and the expression levels of CXCR4, HS and SDF-1 were significantly higher in Ligustrazine group than in the BMT group (P < 0.05).

Eighteen serum samples from patients with insulin-dependent diabetes mellitus (IDDM) and 20 serum samples from healthy human subjects were collected. The frozen sections of the pig pancreas were incubated with these sera, and subsequently incubated with FITC-conjugated goat antihuman IgG and IgM monoclonal antibodies. The reactivity of human PNAbs with various porcine pancreatic cells was determined by indirect immunofluorescence staining technique. The results showed that 55.6% of IDDM patients and 55.0% of healthy human individuals contained PNAbs against porcine endocrine cells. However, the percentage of strongly reacting sera in the patient group was significantly increased as compared with that in the control group. All used sera from IDDM patients and 95% of sera from healthy controls could react to one or more of the various pancreatic cell types, including: endocrine cells, exocrine cells, vascular endothelial cells, ductal epithelial cells and macrophages. The isotypes of PNAbs contained both IgG and IgM. In view of strongly positive reactivity of PNAbs with various porcine pancreatic cells, pretransplantly cross-matching test and graft pretreatment may be necessary for survival of islet transplants.","PeriodicalId":73995,"journal":{"name":"Journal of Tongji Medical University = Tong ji yi ke da xue xue bao","volume":"21 1 1","pages":"59-61"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"52207973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients were randomly divided into two groups: control group (group C) and propofol group (group P). Anesthesia was maintained in the patients in group P with 6 mg.kg-1.h-1 propofol, and those in the group C inhaled 1%-2% isoflurane. The blood samples were taken before CPB, at the 30th min of CPB, at the end of CPB, and 2 h and 24 h after CPB to measure the content of erythrocyte intracellular calcium ion (E-Ca2+), Ca(2+)-Mg(2+)-ATPase and Na(+)-K(+)-ATPase activities, index filtration of erythrocytes (IF), mean corpuscular volume (MCV) and the concentration of plasma free hemoglobin (F-HB). Results showed that in the control group, E-Ca2+, IF, MCV and F-Hb were gradually increased and Ca(2+)-Mg(2+)-ATPase and Na(+)-K(+)-ATPase activities were decreased. The increase of E-Ca2+ was linearly paralleled to IF, MCV and F-Hb. In propofol group, all the above-mentioned parameters were significantly improved (P < 0.05). This study suggests that erythrocyte injury is related to elevation of intracellular calcium during CPB and propofol has a protective effect on erythrocyte injury.","PeriodicalId":73995,"journal":{"name":"Journal of Tongji Medical University = Tong ji yi ke da xue xue bao","volume":"21 1","pages":"65-7"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"52208147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
