Objective: To summarize surgical result of single ventricle with total anomalous pulmonary venous connection (TAPVC) in relevant patients.
Methods:A total of 25 patients of single ventricle with TAPVC treated in our hospital from 2008-09 to 2016-03 were summarized. The patients were between 5 days to 14 years of age with body weight at (3.3-49.5) kg. There were 22 patients with supracardiac type TAPVC, 1 with infracardiac type TAPVC and 2 with mixed type TAPVC;in addition,17 cases having complete atrio-ventricular canal defect, 2 having tricuspid atresia, 4 having more than moderate atrio-ventricular valve regurgitation, 5 having pulmonary atresia and 9having pulmonary venous obstruction.
Results:There were 5/25 (20%) patients died at the early stage for low cardiac output syndrome. Followed-up study was conducted in 20 survivals for (1-65) months and 7 patients had re-surgery including 5 with modified Fontan operation, 1 with atrio-ventricular valve replacement due to severe atrio-ventricular valve regurgitation, 1 with pulmonary venous stenosis repair+atrio-ventricular valve replacement due to pulmonary venousobstruction and severe atrio-ventricular valve regurgitation. 3 patients died during followed-up period because of low cardiac output syndrome, protein lost intestine disease and neurological injury respectively. The rest survivals had good general condition, no residualpulmonary venous obstruction was found.
Conclusion: The patients of single ventricle with TAPVC were frequently associated with right atrial isomerism and complex cardiac anomaly;surgical treatment still having the high mortality.

Hepatocellular carcinoma (HCC)is a disease with high incidence and mortality and has become a serious threat to human health. So far,none of the available markers can be used alone for early diagnosis of HCC.Recently identified serum markers with potential clinical value for early diagnosis of HCC are summarized,and their diagnostic sensitivity and specificity,as well as their applications in assessment of progression of the disease,are reviewed.It is suggested that alpha -fetoprotein should be used in combination with other serum markers to achieve accurate diagnosis of HCC at early stages.

Objective To observe the clinical efficacy of acupuncture plus Chinese medicine iontophoresis in treating dry eye syndrome.Method Sixty-two patients with dry eye syndrome were randomized into a treatment group and a control group, 31 cases in each group. The treatment group was intervened by acupuncture plus Chinese medicine iontophoresis, while the control group was intervened by artificial tears. After 4-week treatment, the changes of tear secretion, tear film break-up time (BUT) and symptoms score were observed, and the clinical efficacies were compared.Result The total effective rate was 87.1% in the treatment group versus 61.3% in the control group, and the between-group difference was statistically significant (P<0.05). The total symptoms score, tear secretion and BUT were significantly changed after the treatment in both groups (P<0.05). After the treatment, the total symptoms score, tear secretion and BUT in the treatment group were significantly different from those in the control group (P<0.05).Conclusion Acupuncture plus Chinese medicine iontophoresis is an effective method in treating dry eye syndrome.

OBJECTIVE:To investigate clinical efficacy and safety of Fluticasone furoate nasal spray in the treatment of aller-gic rhinitis(AR). METHODS:100 AR patients in our hospital during Jan. 2014-Dec. 2015 were divided into control group and ob-servation group according to random number table,with 50 cases in each group. Both groups received decongestant Oxymetazoline hydrochloride spray. Control group was additionally given Budesonide spray,once each nostril on the first day,twice each nostril on the second day,increasing suitably according to disease condition,less than 6 times a day for patients younger than 14 years old,less than 8 times a day for patients older than 14 years old;observation group was additionally given Fluticasone furoate nasal spray,once each nostril,qd for patients younger than 14 years old,once each nostril,while morning and night for patients older than 14 years old. Both groups received treatment for consecutive 30 d. The total nasal symptoms score(TNSS),total eye symp-toms score (TESS),total nasal resistance (TNR) under 75,150 Pa,nasal minimum cross-sectional area (MCA) and the occur-rence of ADR were compared between 2 groups before and after treatment. RESULTS:There was no statistical significance in above indexes between 2 groups before treatment (P>0.05). After treatment,TNSS of 2 groups and TESS of observation group were decreased significantly compared to before treatment,and TESS of observation group was significantly lower than that of con-trol group,with statistical significance (P<0.05). There was no statistical significance in TESS of control group before and after treatment(P>0.05). TNR of 2 groups under 75,150 Pa were significantly lower than before treatment,and the observation group was lower than the control group,with statistical significance (P<0.05). MCA of 2 groups were significantly lower than before treatment,without statistical significance between 2 groups(P>0.05). The incidence of ADR in observation group was significant-ly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Fluticasone furoate is similar to budesonide in the treatment of nasal symptoms of AR patients,but it is better than budesonide in improving eye symptoms and nasal ventila-tion function with milder ADR.

Objective To evaluate the results of direct anastomosis between the main pulmonary artery and right ventricle in the repair of complex congenital heart disease. Methods Between March 2001 and June 2004, seventeen patients with complex congenital heart disease underwent direct anastomosis between the main pulmonary artery and right ventricle. Among them, eleven patients were under 3 years old. Six patients had pulmonary atresia and ventricular septal defect (VSD), 4 had transposition of the great arteries and VSD, 4 persistent truncus arteriosus and 3 TOF with coronary artery straddling RVOT. Twelve patients underwent one stage complete corrective repair and 5 patients received staged procedures. Results There was 1 operative death with hospital mortality of 5.9%. Three out of 5 staged patients succeeded in the second corrective repair. At follow-up ranging from 1 to 40 months, all patients were growing well and their heart function were in NYHA class 0 or I. Conclusion Direct anastomosis between the main pulmonary artery and right ventricle can provide good results in the repair of certain complex congenital heart disease, especially in infant patients without suitable homograft.

Objective To evaluate the outcomes of one-stage repair of aortic coarctation (CoA) and associated cardiac anomalies in infants through a midline sternotomy. Methods Between June 2002 and August 2005, 36 patients (27male, 9 female) underwent surgery for CoA. The age was from 18 days to 8 years[mean (14.3?9.5) months], 27 patients (75%) were younger than 1 year and 18 patients (50%) were younger than 3 months. The body weight was from 3.0 to 23 kg [mean(6.6?3.0)kg]. 27 patients were symptomatic infants and 8 patients were asymptomatic of adults. One patient had recoarctation after repair through a left thracotomy one year ago. The associated cardiac anomalies included ventricular septal defect, patent ductus arteriosus, secundum atrial septal defect, hypoplasia of the aortic arch, transposition of great arteries and subaortic stenosis. 36 cases underwent one-stage operation of extended end-to-end anastomosis through a midline sternotomy. Results One patient died postoperatively with a mortality of 2.8 %. The cause of death was heart and lung function failure. 35 cases were followed up from 4 months to 3 years .One late death occurred. 34 cases were in good condition and no recoarctation. Conclusion Outcomes of one-stage repair of CoA and associated cardiac anomalies in infants through a midline sternotomy is excellent. Technique of extended end -to-end anastomosis may potentially reduce the incidence of recoarctation.

Objective To study the mechanism of the resistance in Acinetobacter baumannii to common antibiotics.Methods Bacterial susceptibility test to ?-lactamatic antibiotics,quinolones,aminogiycosids were done by the Kirby-Bauer method and agar dilution method for 35 isolates.Penicillin-beta-lactamase,AmpCs,Metallo-beta-lactamase,ESBLs were detected by iodine-starch test,3-dimension test,microbiology sensitivity synergic test,disc agar diffusion method respectively.Outer membrane protein was analyzed by SDS-PAGE.Accumulation of ciprofloxacin was determined by direct Fluorescence method.The gene of Tem-1,aac-4 and gyrA were amplified by PCR while the gyrA was sequenced.Results 28 isolates were multi-resistant to common antibiotics in 35 isolates.16 isolates produced Penicillinase,10 isolates produced Cephalosporinase,2 isolates produced metal-beta-lactamase,3 isolates produced ESBLs.The analysis of outer membrane proteins showed that a protein of 29kD disappeared and 26kD protein enhanced in resistant isolates.The accumulation of ciprofloxacin in resistant isolates decreased.After treatment with NaN_3,the drug uptake increased to the normal level.Most of [QX(Y8]Tem-1 gene were positive except 2 drug resistant and 3 sensitive isolates.All of [QX(Y8]aac-4 were negative while gyrA were positive.DNA sequencing analysis revealed there had point mutation in the gyrA gene.Conclusion Beta-lactamase,active drug efflux,outer membrane protein permeability decreasement and gene mutation were the factors contributing to the antibiotics resistance of Abaumannii.

BACKGROUND: Recent studies indicate that after indirect co-culture of neonate rat myocardial cells and bone marrow mesenchymal stem cells, bone marrow mesenchymal stem cells can differentiate into myocardial cells successfully. OBJECTIVE: To induce human bone marrow mesenchymal stem cells (hBMSCs) to differentiate into endothelial cells using human umbilical vein endothelial cells by indirect co-culture. DESIGN, TIME AND SETTING: In vitro study of cell engineering was done at the Medical Research Center of Guangdong Provincial People’s Hospital between January and July 2007. MATERIALS: Small quantities of bone marrow were obtained from 11 children with congenital heart disease but without hematologic diseases through manubrium of sternum puncture in the congenital heart defect corrective surgery after the permission of family member. Umbilical cord of full-term normal delivery healthy newborn was provided by the Department of Obstetrics, the First Affiliated Hospital of Sun Yat-sen University. Fresh cattle jugular vein was provided by Guangdong Dali Meat Cattle Butchery. METHODS: The hBMSCs were isolated and purified using density gradient centrifugation method and were cultured in vitro. Human umbilical vein endothelial cells were obtained from newborn umbilical cord by enzyme digestion. Cell culture insert with semipermeable membrane combined with 6-well plate was used to do indirect co-culture induction. Human umbilical vein endothelial cells were expanded in the cell culture insert, passage 3 bone marrow mesenchymal stem cells were expanded in the 6-well plate outside the culture insert at the density of 1?105 cells/well, the initial ratio of the two kinds of cells was 1:5, then low-glucose DMEM culture solution containing 10% fetal bovine serum was added, cells were cultured for 14 days. Co-culture of bone marrow mesenchymal stem cells and bone marrow mesenchymal stem cells was used as control. Introduced endothelioid cells were cultured and then seeded on the cell-free cattle jugular vein intravascular stent. MAIN OUTCOME MEASURES: Morphology changes of induced cells; introduced endothelioid cell surface antigen detected through immunocytochemical staining; the growth and adhesion condition of endothelioid cells on the intravascular stent observed under scanning electronic microsope. RESULTS: The morphologies of introduced endothelial cells were uniform, introduced endothelial cells presented a cobblestone-like appearance, they amplified fast and expressed endothelial cell-specific surface marker CD31 and vWF and the positive rate was over 99%. They also could form a continuous unicellular layer on the cell-free cattle jugular vein intravascular stent. CONCLUSION: Human umbilical vein endothelial cells can induce hBMSCs to differentiate into endothelial cells successfully and to adhere and grew on the cell-free cattle jugular vein intravascular stent through indirect co-culture method.
