Objective To observe the results of multifocal visual evoked potential (mfVEP) examination in patients with anterior ischemic optic neuropathy (AION) before and ater treatment,and to probe its clinical significance.Methods A total of 90 patients (90 eyes) with AION were examined by mfVEP;the second-order reaction of mfVEP was analyzed.The reaction was divided into upper and lower hemi-field of visual field,or 1 / 4 quadrant visual field (superior nasal,inferior nasal,superior temporal,and inferior temporal).The sum of waves of each response was analyzed and the results in various regions were compared.The features of wave configuration was compared between the AION eyes and the contralateral eye,and between the AION eyes before and after treatment.Results The amplitude and latency of P-wave of mfVEP was 0.198±0.033 and 100.197±7.354 respectively in AION eyes before treatment,and was 0.271±0.024 and 98.567±6.794 in the contralateral eyes;the difference was significant (t=16.556,18.330;P<0.01).The amplitude and latency of P-wave of mfVEP was 0.229±0.016 and 100.104±10.603 respectively in AION eyes after treatment,which differed much from that before the treatment (t=13.649,8.858;P<0.01) and also from that of the contralateral eyes (t=13.649,8.858;P<0.01).Conclusions The amplitude and latency of P-wave of mfVEP may accurately reflect the recovery of local optic nerve damage in AION eyes before and after treatment with good repeatability.AION can be used as a new method for AION diagnosis and detection of the prognosis.

Objective Angiotensin(AngⅡ)is an important proinflammatory mediator in the cardiovascular system.The present study is aimed at investigating the correlation between ceramide and p53 and apoptosis of human umbilical endothelial cells induced by AngⅡ.Methods Human umbilical endothelial cells were cultured in vitro and treated with AngⅡalone or in combination with Losartan(an in- hibitor of AT1),PD123319(an inhibitor of AT2),FB1(an inhibitor of ceramidase),PFT-?(an inhibitor of p53),respectively.The ap- optosis of cells was detected with TUNEL,and p53 expression at protein and mRNA was assessed with Western blotting and reverse tran- scription-polymerase chain reaction(RT-PCR).Results Compared to AngⅡgroup,PD123319 and FB1 could inhibit endothelial cells ap- optosis induced by AngⅡat 24h;hut Losartan and PFT-?could not.Compared to the control group,no statistical difference existed be- tween PD123319 and FB1,but it did exist between Losartan and PFT-?.FB1 and PFT-?down-regulated the p53 expression at the protein and mRNA levels.Conclusion In the process of apoptosis induced by AngⅡ,AngⅡcan induce the activation of ceramide by binding with AT2.AT2 and Ceramide play a key role in the endothelial cells apoptosis induced by AngⅡ.Ceramide may be situated in the upper stream of p53 and induce the apoptosis by p53 pathway.

Objective To investigate the change of plasma visfatin in patients with coronary heart disease and its clinical significance.Methods A total of 310 patients with coronary heart disease (ACS group:n =217; SAP group:n =93) and of 90 healthy subjects with a matched age and gender were included in this study.The plasma concentration of visfatin of each subject was measured using ELISA assay,and each patient underwent selective coronary angiography examination.A total of 85 cases of patients in CHD group underwent 64-slice CT coronary imaging to evaluate the main plaque within the coronary.Results The visfatin,LDL,BMI,blood glucose levels was significantly higher in CHD group[ ( 128.18 ± 13.86)ng/ml,(3.63 ± 1.48) mmol/L,( 26.18 ± 1.82) kg/m2,(7.25 ± 2.03 ) mmol/L] than in control group [ (75.96 ± 10.27 )ng/ml,(2.64 ± 0.53 ) mmol/L,( 23.51 ± 0.89 ) kg/m2,(5.11 ± 1.53 ) mmol/L,P < 0.05 ],respectively.The visfatin level in the ACS group [ ( 145.57 ± 19.95 ) ng/ml ] was significantly higher than the SAP group [ (110.79 ±7.78)ng/ml,P <0.05].The visfatin concentration gradually increased with the aggravation of the complexity of coronary lesion types and severity of coronary lesions( P < 0.05).The plasma visfatin concentrations in Soft plaque group and the fibrous plaque group were significantly higher than calcified plaque (P < 0.05).HDL-C and Gensini score of coronary lesions were negatively correlated ( r =- 0.055,P <0.05) ; LDL-C,Glu,and visfatin was positively correlated with coronary lesions Gensini score ( r =0.464,0.279,0.531,P < 0.05 ),respectively.Conclusions The plasma visfatin level in patients with Coronary heart disease increased and affected its lipid metabolism.It may be an important inflammatory factors promoting arterial atherosclerosis occurs and development,which has a certain value to the judgment of coronary lesions and plaque stability combined with 64-slice spiral CT examination.

Taxol could induce tumor cell apoptosis throug h activation of Fas/FasL and caspases. bcl-2 also played an important role in t axol-induced cell apoptosis. Furthermore, taxol had the similar action with lip opolysaccharide on inducing the release of bioactive substances including tumor necrosis factor, interleukin and nitric oxide. There were as well some progresse s in taxol-resistance of tumor cells.

Objective To research and analyze about the quality of life of patients after liver or kid-ney transplantation and return to work aiming at understanding the influence of return to work on their quality of life. Methods The general condition questionnaire and the generic quality of life inventory- 74 (GQOLI-74) were used to survey the quality of life of 30 patients who returned to work after liver or kidney transplantation (the experimental group), the results were compared with 30 cases of the same kinds who did not return to work (the control group). The influence of return to work after liver or kidney transplanta-tion on quality of life was analyzed. Results The total score of quality of life,the score of every dimension and factor were higher in the experimental group than those in the control group. Conclusions Return to work contributes to improvement of quality of life for patients after liver or kidney transplantation.

Objectives To investigate clinic outcome of ticagrelor in treatment of patients with acute ST-segment elevation my ocardial infarction receiving primary percutaneous coronary intervention.Methods Sixty-two consecutive patients with ST segment elevation myocardial infarction (STEMI) receiving primary percutaneous coronary intervention (PCI) were included in this study.The clinic characteristics,thrombolysis in myocardial infarction (TIMI) refuse after PCI,clinical outcomes after 30 d of patients were compared between patients who were treated with ticagrelor (group A 30 cases) and clopidogrel (group B 32 cases).Results There was no difference in the age,proportion of women,hypertension,and diabetics (P > 0.05).TIMI 3 refuse after PCI were significantly higher in group A than group B (96.7% vs 87.5%,P < 0.05).The 30 d re-angina pectoris was lower in group A than group B (3.3% vs 12.5%,P <0.05).However,tiny bleeding of group A was higher than group B (13.3% vs 3.1%,P <0.05).Conclusions Ticagrelortreatment can improve the prognosis of STEMI receiving primary PCI,but increase the risk of bleeding.

Anterior ischemic optic neuropathy (AION) is the ciliary artery-circulatory disorders for the supply of optic nerve head area before the sieve plate prozone and sieve plate district, result in the insufficient blood supply of the optic nerve head and ischemia hypoxia, edema. Clinical manifestations of the type with non-artery inflammatory neuropathy and artery inflammatory neuropathy, which would both eventually lead to the irreversible damage to the optic nerve. In the early phase of AION, the main method is giving a glucocorticoids intravenous drip and a periglomerular injection (or retrobulbar injection) in time, but using the glucocorticoids for a long time or in quantity can cause a series of complications. Therefore, the combination of traditional Chinese and western medicine treatment of AION has become more and more significant in clinic.
