Objective: To investigate the inhibitory effect of Green Tea Polyphenols(GTP) on H2O2-induced lens epithelial cell apoptosis and relevant mechanism.Methods: Separated and cultivated lens epithelial cell,disposed that with GTP,then detected the inhibitory effect of GTP by electron transmission microscopy,flow cytometry and DNA fragmentation assay.The bcl-2,Bax and caspase-3 protein expression were measured with Western-blot in various groups.Results: The apoptosis cells and G1 phase cells increased in the group treated with sodium chloride solution,and the DNA "ladder" was found.In the group treated with GTP,the apoptosis cells and G1 phase cells decreased,and no DNA "ladder".The apoptosis protein bcl-2 increased,however,the Bax and caspase-3 protein decreased.Conclusion: The GTP can protect lens epithelial cells from the oxidative injury and restrain the apoptosis rate of lens epithelial cells and the mechanism was nearly correlated with bcl-2,Bax and caspase-3 protein.

Anastomotic leak after aortic dissection surgery is a common and critical complication.Interventional therapy is less invasive and effective.This case reported that anastomotic leak was found after surgery for type A aortic dissection.The risk of reoperation was high.The minimally invasive method was used to release the ocduder to the anastomotic leak.The effect was accurate.

Objective To estimate the effect of low molecular weight heparin (LMWH) combined with conventional treatment on patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods Literature on randomized control trials( RCTs) with AECOPD treated by LMWH combined with conventional methods was collected in PubMed.The studies were selected according to inclusive and exclusive criteria.The data were extracted,the quality was assessed, and meta-analysis was conducted with RevMan 5.2 software.Results There were twelve RCTs including 879 patients with AECOPD in the current study.The results of meta-analysis showed that:①LMWH could obviously improve PaO2 and PaCO2 of patients with AECOPD as compared with the control group.②There was no statistically significant difference between the LMWH-treated group and control group in the improvement of FEV1 or hematocrit.Conclusion LMWH can significantly improve arterial blood gas analysis in AECOPD, but does not improve FEV1 or hematocrit.

QT dispersion(QTd,equals maximal minus minimal QT interval on a standard ECG) has been shown to reflect inhomogeneity of myocardial repolarization and cardial electrical instability, hence,been proposed to be associated with ventricular arrhythmias.But the intrinsical mechanism of QTd is incompletely understood. Contributing to QTd are differences of action potential duration(APD) in the three-dimensional structure of ventricular myocardium, which is identified to own three cell subtypes:endocardial, midmyocardial(M cells) and epicardial cells.And findings suggest that regional differences in the duration of the M cell action potential may lead transmural and spatial dispersion of repolarization. Autonomic nerves by combining receptors on the myocardial cells,especially M cells affect significantly the APD.Concordance between heterogeneity of ventricular myocardium and heterogeneity of autonomic innervation in heart provide support for the role of autonomic nerve in the generation of the QT dispersion.

Background Cell immunologic therapy for retinoblastoma(RB)is becoming a hot research topic.Cancer-testis antigen is a human immunogenic protein and is used to treat some tumors.However,its effect on RB has not been investigated.Objective The present study was to discuss the antigen specific anti-tumor effect of cytotoxic T lymphocytes(CTL)induced by the cancer-testis antigen,NY-ESO-1-sensitized dendritic cells(DCs),on human RB.Methods PCR was performed to amplify target gene fragments from the NY-ESO-1 plasmids,and then the target gene fragments were digested with the restriction enzymes SalI and EcoRI.Harvested fragments were inserted into the pDC316 plasmid to construct the recombinant plasmid pDC316/NY-ESO-1.The expression of NY-ESO-1 protein in human RB cells strain,HXO-RB44,was detected by immunofluorescence and Western blot.Monocytes were isolated from 60 ml of peripheral blood from a healthy donor using Ficoll density-gradient centrifugation with a cell density of 1 × 107/ml.DCs isolated from blood were stimulated with recombinant human granulocyte-macrophage colony stimulating factor(rhGM-CSF)and recombinant human interleukin-4(rhIL-4).The recombinant plasmid pDC316/NY-ESO-1 was transfected into DCs and the DCs were co-cultured with T lymphocytes.The resultant CTL were used as effector cells.The growth of the CTL was detected by MTT assay.The CTL were then added into the growth medium used for culturing HXO-RB44 cells and the vitality of the HXO-RB44 cells was assayed by MTT assay.Results The sequence of the cloned DNA fragment of the recombinant plasmid pDC316/NY-ESO-1 was conforms with the sequence of the NY-ESO-1 gene.The expression of the NY-ESO-1 protein in HXO-RB44 cells was tested by immunofluorescence and Western blot.DCs were successfully induced with rhIL-4 and rhGM-CSF from PBMC.The recombinant expression plasmid pDC316/NY-ESO-1 was successfully transferred into DCs.These DCs had high expression of surface molecules such as HLA-DR(42.1％),CD80(54.2％),CD83(39.7％)and CD86 (94.8％).The CTL that was induced by DCs-sensitized with NY-ESO-1 specifically killed HXO-RB44 cells.CTL induced by the sensitized DCs had a stronger cytotoxic effect against HXO-RB44 cells compared with un-sensitized DCs and CTL un-induced with DCs,as shown by MTT asssay(P＜0.05).The anti-tumor activity was highest when the ratio of effector to target was 75∶1(P＜0.05).Conclusions DCs transfected by the recombinant plasmid pDC316/NY-ESO-1 can induce the proliferation of allogenic CTLs,which showed a specific anti-tumor effect against HXO-RB44 cells.These results present a new type of immunotherapy for the treatment of RB.

Twenty-eight cases of Infantile Tourette's syndrome were treated by puncturing Back-Shu points. In 28 cases of the patients, the results showed cure in 6 cases, effect in 21 cases and failure in one case, and the total effective rate in 96.4%.

Objective To evaluate the value of MRI in diagnosing the bucket handle tear (BHT) of the knee meniscus.Methods Eighty four knees which underwent both MRI and arthroscopy (AS) examinations were analyzed. Results of AS were used as golden standard to evaluate the results of MRI. The evaluating criteria included primary reports, central displaced fragments of meniscus (CDFM), double posterior cruciate ligament sign (DPCLS) and the absent bow tie sign (ABTS). Results For MRI diagnosing BHT, the sensitivity and specificity of primary reports were 43% and 87%, respectively; the sensitivity and specificity of CDFM were 72% and 87%, respectively; the sensitivity and specificity of the DPCLF were 31% and 97%, respectively; and the sensitivity and specificity of the ABTS were 71% and 69%, respectively.Conclusions When MRI was applied to diagnose BHT, the CDFM had higher sensitivity and specificity, while the ABTS had higher sensitivity and lower specificity. The DPCLF had the highest specificity and the lowest sensitivity.

Objective To study the improvement of sleep and life quality in chronic insomina patients with abdominal acupuncture. Methods Ninety patients were randomly divided into study group and control group. The study group were treated with abdominal acupuncture combined with hypnotics, and control group of with pure hypnotics. Ten treatments formed a course. The therapeutical effect was assessed with Pittsburgh Sleep Quality Index (PSQI) and Questionnaire SF-36 before and after treatment and 2 weeks after treatment respectively. Results The significant improvement was obtained in aspects of general effective rate right after the treatment, general score of PSQI and score of Questionnaire SF-36, and very significant improvement two weeks after the treatment not only in PSQI scores in sleep quality, sleep efficiency, daytime function and hypnotics but in SF-36 score. Conclusions Abdominal acupuncture can treat chronic insomnia through regulating body environment so as to improve sleep and life quality, and eliminate the hypnotic side effects.
