OBJECTIVETo explore the mechanism of electroacupuncture therapy on Parkinson's disease (PD).

METHODSFifty Wistar rats were randomly divided into a normal group, a sham-operation group, a model group, a Fengfu-Taichong group and a Shuanggu Yitong group. PD model was duplicated by microinjection of 6-Hydroxyl-Dopamine into right corpora striata, and by microinjection of normal saline in sham-operation group. Rats in normal group, sham-operation group and model group were not treated. In Fengfu-Taichong group, the rats were treated by electroacupuncture at "Fengfu" (GV 16) and "Taichong" (LR 3) on the basis of the PD model, and by electroacupuncture at "Fengfu" (GV 16), "Taichong" (LR 3), "Guanyuan" (CV 4) and "Zusanli" (ST 36) in Shuanggu Yitong group, once daily for 2 weeks. GDNF and Ret expression were detected by immunohistochemistry and western blotting, respectively.

RESULTSThe number of GDNF positive cells and the content of Ret receptor increased significantly in the two electroacupuncture groups compared with those in the other groups (all P < 0.01), and the expression of GDNF increased significantly in Shuanggu Yitong group compared with that in Fengfu-Taichong group (P < 0.01).

CONCLUSIONElectroacupuncture can not only increase the expression of GDNF, but also enhance its effect. "Shuanggu Yitong" method is better than simple acupuncture at "Fengfu" (GV 16) and "Taichong" (LR 3) in increasing expression of GDNF.

OBJECTIVETo report the results of transcatheter interventional therapy (TIT) of congenital heart disease (CHD) register from 23 medical centers in China.

METHODIn this retrospective multicenter registry study, clinical data from 5808 patients who underwent TIT between January 2008 to December 2010 in 23 Chinese medical centers in 14 cities were analyzed.

RESULTSProcedure was successful in 5720 cases (98.5%), success rate was 99.5% for PDA, 98.8% for ASD, 97.4% for VSD and 98.5% for pulmonary stenosis (PS). Multivariate regression analysis showed that PDA size and procedure time, age and procedure time, distance from VSD to AV were significantly associated with the procedure success rate of PDA, ASD and VSD closure, respectively. Early complications occurred in 306 cases (5.3%), 36 cases (0.6%) experienced major complications including device embolization in 7 cases, serious aorta regurgitation in 5 cases, serious tricuspid regurgitation in 4 cases, tricuspid stenosis in 2 cases, heart block (HB) in 13 cases (2 in ASD and 11 in VSD), cardiac tamponade in 2 cases (1 ASD and 1 PS) and hemolysis in 3 cases. Procedure time and PDA size, ASD size, device size, age and PS degree were risk factors related to the occurrence of the early complications for PDA, ASD and VSD closure and PBPV respectively. The median follow-up time was 15 months (range 1-36 months). The complete closure rate during follow up was 100% for ASD, PDA and VSD and the pressure gradient in PS decreased to normal range in all PS patients. Late complications occurred in 15 cases (0.2%), of which 3 cases needed surgery intervention and permanent pacemaker was implanted in 1 patient. There was no death during procedure and at follow-up period.

CONCLUSIONSTIT of CHD offers encouraging results in China. Follow up is warranted to monitor the occurrence of serious complications, especially late complications.

OBJECTIVETo compare the expression of CCL28 in minor and major salivary glands and clarify the role it plays in IgA secreting by minor salivary glands in oral cavity.

METHODSLabial gland and parotid samples were analyzed with real-time fluorescent quantitative PCR assay for CCL28 mRNA. Rank-sum test was used for data analysis using SPSS 10.0 software package.

RESULTSCCL28 mRNA was abundantly expressed in labial glands of healthy adults. Its expression was higher than that in parotids (P<0.01).

CONCLUSIONThe results of this article suggest that the expression level of CCL28 in labial glands is remarkably higher than that in parotids, which reminds us that the high concentration of IgA in minor salivary glands may be associated with their high expression of CCL28.

Objective To explore the diagnosis and therapy experience of vascular ring combined with tracheal compression in infants and neonates.Methods Sixteen cases(including 7 boys and 9 girls,aged 1 day to 12 months)with vascular ring combined with tracheal compression hospitalized in Guangdong General Hospital from Jun.2004 to Dec.2009 were enrolled.In these 16 children,13 cases had congenital heart malformations.All children underwent X-ray,echocardiography and spiral computed tomography examination.Nine cases received bronchoscopy study.Fifteen cases performed surgical division of vascular ring with cardiopulmonary bypass and 1 case underwent vascular ring division and tracheoplasty.Eleven cases received management of congenital heart defect simultaneously.Results Vascular ring anomalies included pulmonary artery sling in 5 children,right aortic arch-left ligmentum/aberrant left subclavian artery in 8 cases,double aortic arch in 1 case,innominate artery compression in 1 case,and pulmonary sling combined with right aortic arch-aberrant left subclavian artery in 1 case.There were 2 ring-sling complex cases in this study.The diagnosis of vascular ring were correctly made by echocardiography in 7 children and made by spiral computed tomography in all 16 cases.Two cases combined with tracheal ring died.In the follow-up study of 11 cases,5 cases were still vulnerable to wheezing.Conclusions The common presentation of tracheal compression in infants and neonates associated with vascular ring are tachypea,stridor,and dyspnea.Multi-slices spiral computed tomography is an important imaging modality.Surgical divisions of vascular ring are safe procedure in most cases and tracheal compression can be relieved by this operation.In patients with severe tracheal stenosis,tracheoplasty should be recommended.

Objective To study the correlation between harm avoidance(HA) personality and fractional anisotropy (FA) with voxel-based analysis (VBA) of diffusion tensor imaging (DTI),and to explore the microstructure of white matter of personality.Methods A total of 333 healthy right handed volunteers,recruited from November 2010 to April 2011,completed the Chinese version of three-dimensional personality questionnaire (TPQ) and Beck depression inventory (BDI),and after that,3D MRI and DTI scan were performed.All preprocessed DTI data were analyzed with SPM8 software in partial correlation analysis by using age and depression scores as controlled variables.The correlation between HA and FA was investigated (a voxel significance thresholdP＜0.001 and a cluster extent threshold of 30 voxels).Results HA was positively correlated with FA of the midbrain,pons,left parahippocampal gyrus,inferior temporal gyrus,middle temporal gyrus,right globus pallidus and bilateral superior parietal lobule,and was negatively correlated with FA of the leg putamen,thalamus and bilateral precuneus.Conclusion FA of the special brain areas is associated with harm avoidance personality dimension.

OBJECTIVEThe aim of this study was to develop a new perimembranous VSD occluder and to evaluate it.

METHODSThe shape of VSD occluder was designed as fabric frame "I" shape that comprised two types: symmetric and asymmetric. The safety, efficacy, feasibility and complication were tested in 22 animal models and in 58 VSD patients in clinical trial. The device were compared with Amplatzer occluder in this study.

RESULTSThe new perimembranous VSD occluder was passed the national material test. In animal study, artificial VSD were all occluded by using the new devices with no complication in follow up except one pig expresented wound infection. In clinical trial, all 58 VSD cases were healing with the new device. One patient suffered with atria-ventricular block 5 days after procedure and was free from AV block with medicine therapy. Compared with Amplatzer perimembranous VSD occluder, the new devices had lower frequency of residual shunt.

CONCLUSIONThe new perimembranous VSD occluder is a safe and effective perimembranous VSD interventional apparatus, and the effect of the new occluders seems not worse than that of the Amplatzer ones.

The effects of different surgical procedures for late pancreatic head carcinoma without gastric outlet obstruction were explored in order to provide theoretical basis to select a suitable operation for these patients. The clinical data of 441 cases of late pancreatic head carcinoma without gastric outlet obstruction were retrospectively analyzed. All patients were divided into 4 groups based on different surgical procedures: group A (101 cases) subjected to Roux-en-Y cholecystojejunostomy; group B (133 cases) undergoing Roux-en-Y choledochojejunostomy; group C (83 cases) given Roux-en-Y cholecystojejunostomy combined with gastrojejunostomy; group D (124 cases) receiving Roux-en-Y choledochojejunostomy combined with gastrojejunostomy. Therapeutic efficacy in each group was evaluated comparatively. Both groups B and D had a lower rate of postoperative obstructive jaundice than groups A and C separately (P<0.05 for all). The data of mean life span showed that both groups B and D had a lower survival rate than groups A and C separately (P<0.05 for all). The incidence of postoperative gastric outlet obstruction in groups A and B was higher than that in groups C and D separately (P<0.05 for all). The gastrojejunostomy had no impacts on the mean life span, and there was no statistically significant difference in complications, average hospital stay (days) and median survival among four groups (P>0.05). For the late pancreatic head carcinoma without gastric outlet obstruction, Roux-en-Y choledochojejunostomy is effective for the reduction of icteric index and the incidence of recurrent jaundice, also offers an opportunity for prolonged survival. Combined use of prophylactic Roux-en-Y gastrojejunostomy during surgical biliary drainage is safe for advanced pancreatic carcinoma with obstructive jaundice, which can decrease the incidence of postoperative gastric outlet obstruction, and has important implications for improving outcomes.
