ObjectiveTo investigate the association between endothelial NO synthase (eNOS) gene G10T polymorphism and the susceptibility of sporadic congenital heart disease (CHD).MethodsThe genotype oneNOS G10T locus was detected and compared in 1323 children with sporadic CHD and 1323 non-CHD children.ResultsCompared with the CC genotype, the AA genotype signiifcantly increased the risk of CHD (adjustedOR=1.42, 95%CI=1.01-2.04). Compared with the CC/AC geno-type, the AA genotype signiifcantly increased the risk of CHD (adjustedOR=1.39, 95%CI=1.08-1.92). Based on stratiifed analy-sis, the AA genotype was associated with the susceptibility of perimembranous ventricular septal defects (adjustedOR=1.56, 95%CI=1.17-2.47).ConclusionsIn Chinese population, theeNOS G10T polymorphism may increase the susceptibility of sporadic CHD.

Objective To compare the pharmacodynamics of rocuronium intermittently administered according to body surface area and real body weight and individual differences. Method Forty-two patients undergoing elective surgery under general anesthesia were enrolled into the body surface area group (BSA group) and the real body weight group (RBW group), with 21 patients in each group. The patients in the two groups were induced with 2ED95 of rocuronium according to body surface area and real body weight (16.64 mg/m2 in BSA group; 0.6 mg/kg in RBW group). Whenever T1 recovered to 10%, a dosage of 0.5ED95 was administred repeatedly for 30 min before the end of the operation. The time of neuromuscular blockade and recovery of muscle relaxation were recorded, and the dosage of rocuronium was also recorded. Results No significant difference in each index of neuromuscular block time-effect was found between the two groups (P > 0.05). The single dosage and maintainance amount of muscle relaxation were less in the BSA group than that in RBW group (P < 0.05). Compared with the RBW group, the single dosage, dosing intervals, pharmacological duration and the time TOFr recovered to 0.7 between the different individuals were less in the BSA group (P < 0.05). Conclusion The intermittent administration of rocuronium can maintain the same clinical efficacy according to body surface area as that according to real body weight , with significantly less dosageand reducing the differences of individuals in blockade time-effect of muscle relaxation.

Objective To evaluate the clinical effect of posterior decompression, internal fixation and interlaminar fusion for the treatment of severe osteoporotic vertebral fracture and collapse complicated with spinal canal encroachment. Methods A retrospective study was carried out in 27 cases of severe osteoporotic vertebral fractures complicated with spinal canal encroachment. The patients were treated with posterior decompression, internal fixation and interlaminar fusion during the period from January 1, 2009 to December 31, 2014. All patients were given vertebral pedicle screw fixation after pedicle augmentation with bone cement. The pain scores of visual analogue scale(VAS), Oswestry Disability Index(ODI), Cobb angle , thoracolumbar Cobb angle and the recovery of neurological function(estimated by Frankel grading system) of the patients were compared beforeoperation, one week after operation and at the end of follow-up. The incidences of internal fixation failure, adjacent vertebral fracture and bone cement leakage also were recorded. Results The patients were followed up for an average of 27 months. The spinal canal occupation rate caused by fracture fragment of posterior vertebral wall was 27.41%~63.85%, with an average of(43.24 ± 10.61)%. Postoperative VAS pain scores, ODI, Cobb angle and thoracolumbar Cobb angle were statistically different from those before operation (P < 0.05). The correction rate for Cobb angle and thoracolumbar Cobb angle was (63.31 ± 23.47)%, (61.91 ± 17.54)%respectively. At the end of the follow-up, the correction loss rate for Cobb angle and the thoracolumbar Cobb angle was (15.38 ± 39.92)%, (21.79 ± 32.20)% respectively, the difference being insignificant compared with those one week after operation(P>0.05). In respect of Frankel grading of neurological function at the end of the follow-up, 6 cases were in grade D and 19 cases were in grade E, but the differences were insignificant compared with those before operation (P > 0.05). None of the patients had surgical site infection, screw looseness or breakage, or rod breakage during the follow-up period. There were 8 patients with asymptomatic bone cement leakage after operation. Vertebral compression fractures recurred in 5 patients, of which 2 had adjacent vertebral fractures and 3 had non -adjacent segment. Conclusion The therapy of posterior decompression, internal fixation and interlaminar fusion is effective for the treatment of severe osteoporotic vertebral fracture and collapse complicated with spinal canal encroachment by obviously relieving pain, improving the physiological function of the spine and stabilizing the spine.

Objective To investigate continuous infusion and inermittent injection of cisatra-curium for deep neuromuscular blockade during laparoscopic surgery and to compare the effectiveness and safety.Methods Sixty ASA Ⅰ or Ⅱ patients,aged from 18 to 65,undergoing selective laparo-scopic gastrointestinal surgery with general anesthesia were randomly divided into 2 groups:group A (n =30)received cisatracurium 0.1 5 mg/kg for intubation,and then continuous infusion of cisatra-curium with micropump at an original rate of 0.2 mg·kg-1 ·h-1 when post tetanic count (PTC)≥3;group B(n =30)was given cisatracurium 0.1 5 mg/kg for intubation,and then intermittent infusion of cisatracurium of 0.05 mg/kg when PTC≥ 3.The cisatracurium consumption,duration of neuro-muscular blocking agent used in group A from induction to the end of infusion and in group B from in-duction to the last infusion,satisfaction of neuromuscular blockade (grade 0-10)of the surgeons,the time of T1 recovered to 25%,75%,TOFr recovered to 0.7,0.9,fulfillment of tongue depressor test,the incidence of hyoxemia after extubation,pneumonia,atelectasis were recorded.Results In comparison with group B,the cisatracurium consumption in group A was significantly more (P <0.05),and the satisfaction of the surgeons was significantly higher at the beginning,1 h,2 h of the operation (P <0.05).The satisfaction of the surgeons respectively showing no significant differences between the two groups at the end of the operation.Recovery index (T1 from 25% to 75%),time of TOFr recovery to 0.7,0.9 in group A was increased,but not statistically.Two patients (7.1%)in group A had hyoxemia after extubation while 1 (4.2%)in group B,the incidence rate was not signifi-cant;3 patients (10.7%)in group A was unable to perform sustained tongue depressor test while 4 (1 6.7%)in group B,the incidence was not significant;all of the patients did not suffer pneumonia and atelectasis.Conclusion Continuous infusion cisatracurium during laparoscopic procedures for deep neuromuscular blockade is effective and safe.The dose of cisatracurium is bigger,and muscular relax-ation would be deeper compared to intermittent infusion.Continuous infusion may prolong the working time of muscle relaxant,but have on influence on the residual effect of muscle relaxant.

Objective To investigate the characteristics of the newly discovered tricuspid injury during the fol-low -up of the patients with interventional transcatheter closure for perimembranous ventricular septal defect (VSD). Methods A retrospective analysis of clinical data was performed in the successful completion of membranous VSD in-tervention from March 2003 to April 2015,and 11 cases of serious tricuspid injury in children were found during the fol-low -up.Results Among 11 children,10 cases underwent surgery again,and in 7 cases of them with pseudoaneurysm of perimembranous septum,the occluders were deviated toward the right ventricul which caused valvular inadequacy for plate winding closures,extrusion and wear of tricuspid chordae and /or leaflet by right ventricul(RV)disc.Among them,1 case was caused by leaflet fusion tear and tricuspid valve insufficiency;3 cases without pseudoaneurysm were caused by a spindle like RV disc recovery structure protruding into the right ventricle,and then the disc squeezed the tricuspid tendinous cord or leaflet and the right ventricular disc nut wrapped tendon of tricuspid valve finally leading to tricuspid valve insufficiency.There was a small amount of tricuspid regurgitation after surgery;the cardiac size and car-diac function returned to normal.One case did not receive surgery,and at present the right atrium and right ventricle were significantly enlarged,and the activity was limited.Conclusions Tricuspid injury discovered newly after perimem-branous VSD interventional therapy is more common in pseudoaneurysm with large tumor occluding the right ventricular disc resulting in poor formation,and it is important to consider these factors in choosing the size of the occluder and the operation.Long term follow -up mechanism should be established for the treatment of VSD after interventional therapy.

Objective To explore the mechanism of immunoregulation by investigating the effects of polysaccharides from Millettia speciosa Champ (MSC) on proliferation of spleen lymphocyte and secretion of cytokine in mice.Methods The effects of MSC polysaccharides on Con A-induced spleen T lymphocyte proliferation were determined by MTT.The contents of TNF-α, IL-6 and PGE2 were determined by ELISA.Results The Con A-induced T lymphocyte proliferation was significantly increased by MSC polysaccharides at the concentrations from 50 to 200 μg·mL-1.Coupled with TNF-α and IL-6 were significantly increased while PGE2 was significantly decreased.Conclusion MSC polysaccharides could increase proliferation of spleen lymphocyte and enhance the immune responses by increasing the secretion of TNF-α and IL-6 in mice.

Objective:To explore the effect of group psychotherapy on damage of theory of mind (TOM) in patients with early-onset schizophrenia.Methods:Totally 60 patients with early-onset schizophrenia were included and divided into the intervention group (n ＝ 30) and the health education group (n ＝ 30).The patients in the intervention group were offered 10 twice a week 2-hour sessions of group psychotherapy,and those in the control were offered group health education twice a week.All participants completed baseline measures and post-intervention measures with the Eye Emotion Recognition and Theory of mind Picture-sequencing Task (TOM-PST).Results:Totally 23 patients in the intervention group and 29 patients in the health education group finished the post-intervention measures.After 5-week intervention,subscores of sad and fear and total score of emotion recognition,total score of TOM-PST,understanding first order error belief,second order error belief,third order error belief,sense of reality,detecting fraud compared to baseline had statistically significant difference in intervention group.In health education group,subscores of joy emotion recognition,understanding first order error belief,third order error belief,total score of TOM-PST compared to baseline had statstically significant difference.The patients with group psychotherapy got higher scores of total score of TOM-PST and understanding second order error belief and third order error belief than the health education group after 5-week intervention (P ＜ 0.05).Conclusion:This study suggests the group psychotherapy could partially improve theory of mind with early-onset schizophrenia,and promote the recovery of social cognition.
