Objective The cardiac synchronization therapy (CRT) was proven to have good treatment for the cardiac conduction disorders patients with serious heart failure. But many disadvantages were gradually be noticed, such as difficulty of sinus electrode implantation, coronary sinus injury and bleeding, still one third CRT cases remain unchanged cardiac function.Recently the epicardial lead CRT therapy by the cardiac surgeons appears promising to provide better clinic resynchronization.The aim of this research is to explore the clinical value of surgical epicardial lead CRT for the cardiomyopathy heart failure with micro-invasive thoracoscopy techniques. Methods During April 2007 to Sep 2009 eleven patients were diagnosed as advanced heart failure with cardiac dysynchronization proven by the ECG and tissue Doppler echo examination. The dysynchronization parameters of tissue Doppler echo includes left ventricle maximize delay time , the left dysynchronization index (Ts-SD), the inter-ventricle mechanical delay time (IVMD), left ventricle end-dilation diameters (LVEDD) and the left ventricle ejection fraction (LVEF). All the patients got the consent agreement before the surgery. In the hybrid operation room the right atrial and ventricle endocardial electrodes were placed firs guided by X ray under the general anesthesia and double lumnen incubation. Then the thoracoscope techniques were used to explore the left ventricle lateral wall. The right atrial and ventricle electrodes were connected into the three chamber pacemaker. The Tissue Doppler Echo TEE technique was used to check which part of the left ventricle lateral wall is suitable for the idea CRT therapy. Usually the latest activated part of the left ventricle wall is the goal place. Then the epicardial electrode was fixed with 4-0 prolene suture at the idea place. All the cases were performed by the same surgeons group in the same medical center. The resynchronization features were examined after surgery and during the follow up. Results The endocardial and epicardial electrodes were implanted successfully without any serious complication. All patients were weaned and discharged without any adverse cardiac episodes. There is no mortality during the follow up period. All the patients received the β-blokers, diuretics, ACEI/ARB and other traditional medicine for the heart failure.The Tissue Doppler showed the E peak wave separated form the A peak which means the good resynchronization between the atrium and the ventricle. After surgery during the follow up the left ventricle maximize delay time decreased from (393.4 ±40.2 ) ms to ( 102.1 ± 34.6) ms, the left dysynchronization index (Ts-SD) decreased from (145.2±29.3)ms to(51.0±21.4) ms, the inter-ventricle mechanical delay time (IVMD) decreased from (59.1 ±23.4) ms to (31.2 ± 11.5 ) ms, left ventricle end-dilation diameters increased from (73.1 ± 13.4) mm to (63.2 ± 6.7) mn and the left ventricle ejection fraction increased from 0.32 ±0.04 to 0.41 ±0.07. Conclusion The micro-invasive surgical synchronization therapy could get good CRT result for the cardiomyopathy heart failure patients. Some patients traditionally in the waiting list for the heart transplant could be considered for the CRT therapy candidates.

Background Many methods are widely studied to improve the therapeutic effect of trabeculectomy for glaucoma,and the clinical effectiveness of the amniotic membrane application during trabeculectomy is one of the research hotspots.Objective This study was to evaluate the efficacy and safety between trabeculectomy with (TE-AMT) and without amniotic membrane transplantation (TE-noAMT) for treating glaucoma.Methods Articles published from 1965 to December 2010 were searched from The Cochrane Library,PubMed,EMBASE,CNKI,Chinese Biomedicine Database,internet by computer,and manual search then was performed according to the predetermined strategy.Randomized controlled trials (RCT) on TE-AMT and TE-noAMT were included.The quality of included articles were scored based on Jadad table,and the relative parameters and information were extracted,including author,design of the trials,country,number of eyes and patients,gender,follow-up duration,age,classification of glaucoma,baseline IOP and loss rate.The main analysis indicators were the percentage of IOP reduction,completely operative successful rate,qualified success rate and adverse events.The pooled estimates were carried out with RevMan version 5.0 software.Results Nineteen RCTs documents were reviewed by meta-analysis with the Jaded scores ≥3 in 2 papers and ＜3 in 17 papers.Total 977 eyes of 818 patients were included.The weighted mean differences (WMD) of the percentage of IOP from baseline were (WMD =8.47％,95％ CI:5.20-11.75) at 6 months and (WMD=9.37％,95％ CI:4.97-13.77) at 12 months postoperatively.Relative risk (RR) of complete success rate and qualified success rate at postoperative 6 months were (1.40,95％ CI:1.19-1.65) and (0.47,95％ CI:0.22-1.00),respectively.RR values of adverse event such as shallow anterior chamber,hyphema,hypotony and choroidal detachment,failed filtering blebs at 6,12 months were 0.51 (95 ％ CI:0.30-0.85),0.43 (95％ CI:0.20-0.92),0.51(95％CI:0.26-1.00) and 0.57(95％CI:0.14-2.31),0.31(95％CI:0.20-0.47),0.31 (95％ CI:0.17-0.55),respectively.Conclusions TE-AMT appears to have better efficacy in lowering IOP,increasing complete success rate and reducing adverse event I in comparison with TE-noAMT.

Objective To analyze the changes in the expression of Toll-like receptors 4 (TLR4) and 7 on the surface of murine bone marrow-derived dendritic cells following dengue virus type 2 (DEN2) infection.Methods DEN2 NGC strain was infected into BALB/c suckling mice through intracranial injection and injected into C6/36 cells to induce the in vivo and in vitro proliferation of DEN2, respectively.RT-PCR was performed to identify DEN2 RNA.Reed-Muench method was used to determine the 50% tissue culture infective dose (TCID50) of DEN2.Dendritic cells (DCs) were prepared by stimulating bone marrow cells isolated form C57BL/6 mice with IL-4 and GM-CSF and then identified by flow cytometry.The prepared murine bone marrow-derived DCs were infected with DEN2 and observed with direct immunofluorescence assay.Dynamic changes in the expression of CD11c, CD86 and I-A/I-E molecules on DCs after DEN2 infection were detected by flow cytometry.Levels of DEN2 RNA and the expression of TLR4 and TLR7 at mRNA level were dynamically detected by real-time quantitative PCR.Results The TCID50 of DEN2 to C6/36 cells was 10-5.8.Murine bone marrow-derived DCs were acquired with a purity of 70% and could be infected with DEN2 in vitro.The percentages of CD86 and I-A/I-E molecules on the surface of DCs infected with 1×105 TCID50 of DEN2 were statistically different from those of the negative control group.Neither of the two groups showed a significant difference in the percentages of membrane molecules over time.However, the percentages of membrane molecules on DCs increased with increasing viral load.Compared with the negative control group, the levels of DEN2 RNA in infection groups were increased with increasing virus load, while the expression of TLR4 and TLR7 on DEN2 infected-DCs at mRNA level was decreased with increasing viral load.Conclusion DEN2 infection promotes the maturation of DCs.Expression of TLR4 and TLR7 on DEN2 infected-DCs at mRNA level decreases with increasing viral load, which suggests that TLR4 and TLR7 are closely related to viral infection and play a certain role in the pathogenesis of DEN infection.
