[Effects of Mercury Pollution on Soil Organic Carbon Stability and Carbon-fixing Microbial Communities].

To elucidate the effects of Hg pollution on soil organic carbon stability and autotrophic microbial carbon assimilation, the characteristics of soil CO emission rate, organic carbon components, and and functional microorganisms before and after 29 d of Hg pollution were studied using indoor culture experiments and molecular biology techniques. The results showed that the effects of different levels of Hg pollution on soil CO emission rates were different. High levels of Hg （S2,S3,and S5） inhibited soil CO cumulative emissions, whereas low levels of Hg （S1,S4,and S6） promoted soil carbon emissions.

Surgical correction of common atrium without noncardiac congenital anomalies.

Aims: Common atrium (CA) is a rare congenital heart defect. We reviewed our experience of surgical treatment of CA and summarize the clinical features of CA and the key techniques for surgical correction.

Methods: Between August 1984 and August 2010, 37 consecutive cases of CA underwent corrective surgery.

[Study of cardiopulmonary adaptation during exercise in patients after extracardiac conduit total cavopulmonary connection].

Objective: To study cardiopulmonary physiology during exercise in patients after extracardiac total cavopulmonary connection (ECTCPC).

Methods: Twenty-six patients were studied after ECTCPC by exercise testing with bicycle treadmill protocol. Heart rate (HR), blood pressure (BP), respiratory frequency (RF) and pulse oxygen saturation (SpO(2)) were measured continuously; twenty-six patients suffered from Fallot 4 underwent biventricular repair were also studied as control group.

[Surgical treatments and results of pulmonary atresia with ventricular septal defect].

Objective: To evaluate the indication and operative program of ventricular septal defect with pulmonary atresia (VSD-PA).

Methods: From June 1984 to March 2005, there were 32 patients with VSD-PA, which underwent 33 operations. Among them, 15 were males and 17 were females.

[Clinical analysis on surgical treatment of single atrium].

Objective: To summarize the experience of surgical treatment of single atrium.

Methods: From August 1984 to August 2004, there were 33 patients with single atrium in our study. Plastic surgery for mitral valves were performed for 30 cases with mitral insufficiency.

[The treatments and results of tetralogy of Fallot with major aortopulmonary collateral arteries].

Objective: To evaluate the indication and operative program of complete repair of tetralogy of Fallot with major aortopulmonary collateral arteries (TOF-MAPCA).

Methods: From January 2000 to May 2004, 9 patients with TOF-MAPCA including 5 patients with pulmonary atresia underwent complete surgical repair, 6 of them were male and 3 were female. The ages ranged from 3 to 9 years.

[The effects of inhaled nitric oxide on pulmonary vascular resistance in patients after total cavopulmonary connection].

Objective: To study the effects of inhaled nitric oxide (NO) on pulmonary vascular resistance in patients after total cavopulmonary connection (TCPC).

Methods: Fifty-two patients after TCPC were evaluated, of them 24 patients were administered with inhaled nitric oxide in the early postoperative period. The cardiac index (CI) and pulmonary vascular resistance (PVR) were compared before and after inhaled NO.

[Surgical treatment of secundum atrial septal defects in adults over 30 years old].

Objective: To summarize the experience of surgical treatment of secundum atrial septal defects in adults over 30 years old.

Methods: There were 469 patients with secundum atrial septal defects in our study (male 144, female 325; ages 30-68, mean 38.6 years old).

[Surgical treatment on residual shunt after repair of ventricular septal defect].

Objective: To summarize the experience in surgical treatment of residual shunt after repair of ventricular septal defect and investigate the position of the residual shunts.

Methods: Between January 1979 and May 2003, re-operations on residual shunt after repair of ventricular septal defect were performed in 37 patients with congenital heart disease including ventricular septal defect, tetralogy of Fallot, double outlet right ventricle in 19, 17 and 1 patients, respectively. It accounted for 0.

Total cavopulmonary connection with extraatrial tunnel.

Between April 1997 and February 2000, total cavopulmonary connection with an extraatrial tunnel was used to treat 9 cases of complicated congenital heart disease: single ventricle (4), double-outlet right ventricle (3), mitral atresia (1), and tricuspid atresia (1). There was no mortality. One patient developed bacterial endocarditis and required reoperation after 52 days to replace the tunnel.
