Objective To provide clinical experience in the treatment and prevention of complicated acute cardiac tamponade in the course of heart interventional therapy. Methods To analyse the clinical features of patients with acute cardiac tamponade and to investigate the possible underlying mechanism. Results Twenty-one cases experienced acute cardiac tamponade when undergoing heart interventional therapy. Among all the 21 patients with acute cardiac tamponade, 11 occurred from percutaneous coronary interention(PCI) ,6 from the radiofrequency catheter ablation , 1 from the closure of atrial rspetal with amplaty closure service, 1 from the percutaeous balloon mitral valvuloplasty ( PBMV), 2 from temporary pacemaker implantation. Eighteen patients were successfully rescued left no serious sequelae. Three cased died, including two PCI-related death and one temporary-pacemaker-installation-related death. Conclusion Any heart interventional operation is at the risk to cause acute cardiac tamponade. Early identification and appropriate treatment is the key to successful rescue.

Objective To observe activated cerebral areas during the task of writing in second language by early and late acquisition bilinguals and explore the neuropsychological mechanism. Methods Twelve subjects were divided into group of early acquisition high proficiency bilinguals(EAHP) and group of late acquisition high proficiency bilinguals(LAHP). Each subject carried out the task of pseudo-writing and English writing. After functional imaging,statistical parametric mapping was used to compare data of the two tasks through paired- t test in both two groups. A conjunction analysis was conducted between the two groups also. Areas where the metabolism of glucose changed were analyzed. Then, the corresponding images about activated cerebral regions were obtained.Results Cerebral areas where the metabolism of glucose increased in EAHP: bilateral middle frontal gyrus( Z=4.35/2. 01 ), bilateral cerebellum ( Z = 2.97/2.53 ) and left head of caudate nucleus ( Z = 3.07 ), etc. Cerebral areas where the metabolism of glucose increased in LAHP: right superior frontal gyrus(Z=4.06), right cerebellum( Z=4.63), left putamen(Z=2.70) ,etc. Cerebral areas where the metabolism of glucose increased in compared data of LAHP with data of EAHP: right frontal gyrus ( Z = 2.92 ), right temporal lobe( Z = 2.31 ), etc. Conclusion Extensive cerebral cortex and subcortical structures participate the process of writing in the second language. Age of bilingual acquisition is one of the factors affecting cerebral localization of writing in second language.

AIM:To investigate the roles of ClC-3 chloride channels in the regulation of cell cycle and the re-lationship between ClC-3 chloride channels and the cell cycle regulators , such as cyclin D1, cyclin-dependent kinase (CDK)4, CDK6, P21 and P27 in the HeLa cells.METHODS:ClC-3 genes were silenced by the siRNA technique in the HeLa cells.The transfection efficiency of ClC-3 siRNA was detected by real-time PCR.The cell cycle distribution was ana-lyzed by the flow cytometry .The protein expression of ClC-3, P21, P27, CDK4, CDK6 and cyclin D1 was determined by Western blot .RESULTS:ClC-3 was knocked down by ClC-3 siRNA in the HeLa cells .Transfection of the cells with ClC-3 siRNA arrested the cells at G0/G1 phases, decreased the expression of cyclin D1, CDK4 and CDK6, and increased the expression of P21 and P27.CONCLUSION:ClC-3 plays an important role in the cell cycle of HeLa cells through the G 1-S transition point.ClC-3 may regulate the cell cycle progression by up-regulation of cyclin D1, CDK4 and CDK6 expression and/or by down-regulation of P21 and P27 expression.

Objective To explore the protective effect of a small balloon on bifurcation lesions by applying a single stent treatment of coronary bifurcation lesions strategy. Methods Fifty patients with coronary bifurcation lesions were randomly divided into A group and B group( 25 cases for each group ). Patients in A group were treated with the pre-entry protection branch guide wire to complete the main branch balloon pre-dilation,stenting,while in B group were treated with the set aside the branches of a small balloon. The information of main branch balloon pre-dilation,stenting were recorded. The blood flow slowed down,the incidence of side branch occlusion or stent placement,and the incidence of postoperative 24 h troponin I( cTnI) levels were measured. Results Nine cases(36%)in A group occurred lower branch blood flow,which due to 4 cases(16% )with significantly narrow branch stenting,2 cases(8%)with complete occlusion. There were only 2 cases(8%)with decrease branching blood flow in B group,and the difference was significant(P=0. 041, 0. 022). The cases with higher cTnI after 24 h in A group were 11( 39%),significantly higher in group B (3(12 %);P =0. 027 ). Conclusion Compared with the traditional protection guidewire,the approach of setting aside a small balloon to protect important branch can effectively prevent important branch occlusion, branch involvement due to lower incidence of myocardial infarction.

Objective To discuss the effects and methods of the surgical treatment of complex humeral nonunion.Methods Ten cases of scleroid humeral nonunion were treated by compressive interlocking medullary nailing and autografting of iliac bone.Fifteen cases of humeral nonunion combined with osteomyelitis or osteoporosis were treated with grafting of free vascularized fibular flaps.Results All the cases were followed up for six months to six years.They all obtained bone union.The average time of bone union was 3.1 months for the free vascularized fibular grafting group and 3.8 months for the interlocking medullary nail group.Conclusions Compressive interlocking medullary nailing and autografting of iliac bone is effective for scleroid humeral nonunion,while grafting of free vascu- larized fibular flaps is effective for humeral nonunion combined with osteomyelitis or osteoporosis because the free vas- cularized fibular grafting can well reconstruct the defective humerus bone with osteoporosis or osteomyelitis.
