The cardiovascular ion channel disease is one of the main among ion channel diseases.It plays the important effect of cardiovascular disease.Ion channel diseases are responsible for almost all arrhythmias and sudden cardiac death.This text reviews genetic and acquired cardiac ion channel diseases,and associated treatments are introduced briefly.

Objective To investigate the application of numerical simulation technique in supraorbital and frontal osseous defect.Methods The data of the patients with complex supraorbital and frontal osseous defects were obtained by helix CT scan.Numerical model based on the data was built up by computer.And the true model was produced by Rapid Prototyping.Being stimulated before this operation.the model was directly used in the operation.Results All of these 12 patients(one of defect of brow,four fracture of brow and zygoma,seven of old fracture of brow and zygoma)in this study were satisfied and their brows were symmetry after operation.All of them were satisfied after 1 or 2 years,without implantation exposure and transfiguration except one with infection.Conclusion Based on numerical technique difficulties of repairing,complex supraorbital and frontal osseous defect could be resolved by such process as collecting the bone data,stimulating operation by true models,and producing implantation before the operation.The accuracy of these operations can be improved.

Objective To investigate the therapeutic effects of botulinum toxin type A injection and acupuncture on periorbital wrinkles.Methods From May to September in 2015,24 patents were randomly divided into experimental and control group according to random number table:the patients in experimental group were treated with disposable acupuncture needles,20 min for each treatment,once a day,five times each course for courses,2 days interval between the two courses;the patients in control group were treated with 20 units of hotulinum toxin type A injection.The therapeutic results were observed 2 weeks after the treatment by the third-party doctor according to skin wrinkles grading.Results The periorbital wrinkles in both groups improved remarkably,and the wrinkle grading in control group was significantly lower than that in the experimental group (0.67±0.67 vs 1.33±0.61,P＜0.05).The skin quality and facial expression sensation in the experimental group improved significantly when compared with those in the control group.Conclusions Acupuncture can be used as a complementary treatment of periorbital wrinkles,and it improves the skin quality in terms of elasticity and color and keeps the natural facial expression sensation.

Objective To study the pathologenesis and to evaluate an operative method of blepharochalasis. Methods A double eyelid-fold incision was made. The lacrimal glands were found and repositioned into lacrimal glands fossa behind superolateral orbital rim. Then redundant skin and muscles as well as hernia septal fat were removed. Results Twenty-three patients were successfully treated by the mentioned methods from 1998 to 2002. A good clinical results in both function and appearance were achieved. Conclusion It is convenient and effective to treat blepharochalasis through a double eyelid fold incision.

BACKGROUND:Among the factors causing vascular endothelial cell injury,angiotensin Ⅱ(Ang Ⅱ) caused by renin-angiotensin system (RAS), especially by local RAS, plays an important patho-physiological role.OBJECTIVE: To observe the effect of tanshinone ⅡA on the vascular endothelial cells secreting nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) gene expression as well as intracellular Ca2+ level induced by Ang Ⅱ, and investigate the protective effect of tanshinone ⅡA on vascular endothelial cells.DESIGN: Controlled observation experiment.SETTING: Department of Emergency, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: This experiment was carried out in the Experimental Center for Basic Medicine, Tongji Medical College,Huazhong University of Science and Technology from March 2006 to October 2006. Porcine aorta used in this experiment was provided by the Department of Pathophysiology of Tongji Medical College.METHODS: Nitric acid deoxidization method and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the effects of Ang Ⅱ of different concentrations (10-8 to 10-6 mol/L) on endothelial cells secreting NO and eNOS mRNA expression in cultured porcine aortic endothelial cells at different time points (1,6 and 24 hours) separately, then 50 mg/L tanshinone Ⅱ A was respectively added at different time point (0, 6 hours) when Ang Ⅱ was at 10-6 mol/L, and changes in NO production and eNOS gene expression were detected respectively at 1, 6 and 24 hours. Intracellular Ca2+ level was also detected with laser scanning confocal microscopy.MAIN OUTCOME MEASURES: ① NO content. ②eNOS mRNA expression. ③Intracellular Ca2+ level.RESULTS: ① NO production and eNOS mRNA expression were decreased with increase of Ang Ⅱ concentration and prolongation of time (P ＜ 0.01). ② NO production and eNOS mRNA expression in each tanshinone ⅡA-treated group were significantly higher than those in the Ang Ⅱ group. At 1 and 6 hours of tanshinone ⅡA treatment, production of NO and eNOS mRNA expression in the Ang Ⅱ + tanshinone ⅡA group were significantly higher than those in the Ang Ⅱ 6 hours + tanshinone ⅡA group (P ＜ 0.05); There were no significant differences in NO production and eNOS mRNA expression between two groups at 24 hours (P ＞ 0.05). ③Intracellular Ca2+ level in the Ang Ⅱ group was significantly higher than that of control group (P ＜ 0.01), and intracellular Ca2+ level in the tanshinone ⅡA + Ang Ⅱ was significantly lower than that in the Ang Ⅱ group (P ＜ 0.05).CONCLUSION: Tanshinone Ⅱ A has a protective effect on vascular endothelial cells and their functions by suppressing the inhibition of Ang Ⅱ on NO level and eNOS gene expression in cultured porcine aortic endothelial cells.

[ ABSTRACT] AIM:To investigate the effects of BARF1 down-regulation on EBV-positive gastric carcinoma cell apoptosis, and the molecular mechanisms by BARF1 silencing-mediated apoptosis.METHODS: After NUGC3 and SNU719 cells were transfected with NCsiRNA and siRNA, respectively, the protein levels of BARF1, Bcl-2, Bax, cyto-chrome C, caspase 3 and capase 9 were detected by Western blot, and the mRNA expression of BARF1, Bcl-2 and Bax was determined by RT-PCR.The cell viability was measured by the method of Trypan blue exclusion and the cell apoptosis was analyzed by flow cytometry analysis with Annexin V-FITC/PI staining.The expression of the apoptosis-related proteins in the cells transfected with siRNA and NCsiRNA was examined by human apoptosis antibody arrays.Mitochondrial mem-brane potential was determined by flow cytometry.The interaction between Apaf-1 and caspase 9 was confirmed by immuno-precipitation.RESULTS: Compared with untreated and NCsiRNA groups, BARF1 gene silencing significantly inhibited the cell viability, induced apoptosis, and reduced the mitochondrial membrane potential in the NUGC3 and SNU719 cells transfected with siRNA.BARF1 gene silencing up-regulated the expression of pro-apoptotic proteins and down-regulated the expression of anti-apoptotic proteins, and the Bcl-2/Bax ratio was significantly decreased.In BARF1 gene silencing cells, the caspase inhibitor z-VAD-fmk inhibited BARF1 silencing-mediated apoptosis, and significantly increased the levels of cleaved caspase 3 and caspase 9.The concentration of cytochrome C significantly increased as compared with NCsiRNA group, and Apaf-1 interacted with caspase 9 in the cytoplasm.CONCLUSION:BARF1 silencing induces apoptosis via the mitochondrial pathway through regulating the expression of Bcl-2 and Bax proteins in a caspase-dependent manner in the NUGC3 and SNU719 cells.
