Objective To review and sum up experience of surgical repair of single ventricle. Methods Since January 1973 to December 1999, 47 patients with single ventricle have been repaired. Right ventricle type was 17 patients, left ventricle type was 14, and unrecorded type was 16. Surgical procedure consisted of pulmonary banding 1, Fontan operation 23, and bidirection superior cavopulmonary anastomosis 23. Results Seven patients died. The motality was 15%. There was no death in bidirection superior cavopulmonary anastomosis patients. Conclusion For the single ventricle, early surgical intervention is required to prevent pulmonary congestion and severe cyanosis. The bidirection superior cavopulmonary anastomosis can improve single ventricle function secondary to pressure and volume load to decrease surgical mortality and to minimize the risk factors for subsequent Fontan operation.

Objective To investigate the relationship between serum levels of CA15-3, CA-125 and CEA in postoperative breast cancer patients and clinicopathological parameters and pathogenetic condition turnover. Methods From January 2004 to December 2007, 219 breast disease cases with integrity clinical information, admitted to general surgery and oncology department of Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, were collected. The serum concentrations of CA15-3, CA-125 and CEA were determined by chemiluminescent immunoassay(CLIA). Wilcoxon Kruskal Wallis analysis, crosstable analysis and spearman correlation analysis were used to investigate the association between the serum concentration and clinical parameters and pathogenetic condition turnover. Results The serum concentrations of CA15-3,CA-125 and CEA in metastatic breast cancer group were significantly higher than those in nonmetastatic group(P=0.000). The sensitivity of the 3 tumor markers in combination was 64.1% in metastatic breast cancer diagnosis. CA15-3 and CA-125 at the time of initial metastasis were correlated with estrogen receptor state(PCA15-3=0.039, PCA-125=0.049). The level of 3 tumor markers in multiorgan metastatic group were significantly higher than those in single organ metastastic patients(P=0.000). There were significant differences between the levels of CA15-3 and CEA in distant metastatic group and those in local metastatic group (PCA15-3=0.001,PCEA=0.022). Conclusion The high serum concentrations of CA15-3,CEA and CA-125 were useful in monitoring the metastasis. The high serum levels of CA15-3 and/or CA-125 may indicate that the patients will be more sensitive to endocrine therapy.

Objective To investigate the inhibitory effect of ester catechin monomers-EGCG, GCG on the growth of human colon carcinoma cell line SW480 and its potential mechanism. Methods MTT assay, soft-agar colony formation test, Hoechst 33258 stain and flow cytometry analysis were used to determine the inhibitory effect of theasinesin(TS), and its monomers-EGCG, GCG on SW480 growth. Results EGCG, GCG and TS significantly inhibited the growth of human colon carcinoma cell line SW480 in dose-dependent manner, and their half inhibitory concentration (IC 50 ) was 108.88, 183.21, and 83.36?g?ml -1 , respectively. 24 hours after treatment with IC 50 of EGCG, GCG and TS, the colony formation rate of SW480 cells in the experimental group was obviously lower than that in the control group. Hoechst 33258 staining showed typical apoptotic features such as cell shrinkage, nuclear condensation and cell splinter in the experimental group. A subdiploid peak before G 0/G 1 phase in the experimental group was observed by flow cytometry. Conclusion In accord with TS, EGCG and GCG could inhibit the growth of colon carcinoma cell line SW480 cells, the mechanism of which may be related to inducing cell apoptosis.

Objective Infracardiac total anomalous pulmonary venous connection, a rare congenital cardiac defect, is associated with high mortality. A modification was designed for the procedure to reduce the post-operative obstruction in the pulmonary venous. Methods From September 2005 to December 2007, seven patients with infracardiac total anomalous pulmonary venous connection were treated with repair surgery through right side approach. The patients' age at operation was (70.57 ±44.67) days , the weight was (4.07 ±0.87) kg. Three patients had pulmonary venous obstruction, and 2 with small PFO. A modified right - side approach for repairing this defect was used. Results No death occurred after the operation. The postoperative complications included low cardiac output in 5 patients (71.43%), pulmonary hypertension crisis in 3patients ( 42.86% ) , mechanical ventilation for more than 7 days, which happened in 2 patients (28.58%) and pulmonary infection. All of the patients received follow-up. No residual shunt and pulmonary venous return obstruction were identified on echocardiogram(with a velocity from 1.2 m/s to 1.47 m/s). The heart function of patients was within the normal range(EF 0.70 -0.79, FS 0.32 -0.44). Conclusion The modified surgical procedure for the correction of infracardiac total anomalous pulmonary venous connection by right side approach was associated with favorite clinical outcomes, The post-operative outcomes depended on the size of anastomosis between the common vein and left atrium and the patency of the pulmonary venous return. Adequate size of anastomosis and maintenance of the spatial structures in adjacent regions were helpful in decreasing the adverse effect of postoperative obstruction.

The effect of pH on the extracellularpolysaccharide synthesis by Aureobasidium pullulans was studied by addding CaCO3and HCI. Cultivated in P2 liquid medium for 24h,pH dropped to 3. 6 because of strongly producing acid. Under this low pH environment, further fermentation for 120h,only 5. 9g/L of polysacharide was obtained. When grown in MP2 medium contaning0. 5 % CaCOs,the pH was kept above 5.0 during 144 hours,production of polysaccharide increased to 31g/L. The detailed information of effects of controlled pH on polysaccharide production showed an optimal pH value 5. 0 must be maintained through the fermentative period.
