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 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.

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 explore the role of Th17 cells in systemic lupus erythematosus (SLE)with cardiovascular disease (CVD).Methods 61 patients of SLE were collected from September 2011 to March 2013 in the Second Hospital of Hebei Medical University by revised SLE classification standards of ACR in 1997.These patients were divided two groups:22patients of SLE with CVD and 39 patients of SLE without CVD;the control group include 20 healthy.Th17 cells were measured by flow cytometry,IL-1 7 was detected by enzyme-linked immunosorbent assay.The correlation among them and the disease active index were analyzed.Results ①The percent of Th1 7 cells in the group of SLE with CVD,that in the group of SLE without CVD and that in control group were (2.09±0.98)%,(1.75±0.75)% and (0.89±0.44)%,respec-tively.The percent of Th1 7 cells in healthy group were lower than that in SLE with CVD and SLE without CVD group (t=4.717~5.030,P<0.001).The level of IL-17 in the group of SLE with CVD,that in the group of SLE without CVD and that in control group were 85.64±20.76 pg/ml,75.25±28.14 pg/ml and 35.06±6.58 pg/ml respectively,and the serum of IL-17 in healthy group were lower than in SLE with CVD and SLE without CVD group (t=6.275~9.954,P<0.001). There were no significant difference of Th1 7 cells and IL-1 7 between SLE with CVD and SLE without CVD groups (t=1.520,P>0.05;t=1.513,P>0.05).②The level of IL-17 were correlated positively with SLEDAI and the anti-double strand DNA (r=0.393,P=0.008;r=0.558,P<0.001),were correlated negatively with complement C3 (r=-0.423,P=0.005).The percent of Th17 cells in CD4+T cells were correlated positively with SLEDAIand the anti-double strand DNA (r=0.681,P<0.001;r=0.492,P=0.015)were correlated negatively with complement C3 (r=-0.534,P=0.027).Con-clusion The level of Th1 7 cells and IL-1 7 were high in SLE,and they were related with the disease activity.The cardiovas-cular factor had not affect the expression of Th1 7 cells and IL-1 7 in SLE.

Objective A retrospective analysis were conducted to identify the effect of bypassing the emergency department on 30-days outcomes of patients with acute myocardial infarction undergone primary percutaneous coronary intervention ( PPCI) . Methods From June 2014 to April 2015, 187 patients underwent PPCI in Kunming General Hospital were included. 13 patients were excluded owing to their incomplete follow-up data. The total 174 patients were divided into two groups: the control group (n =59) who did not bypass the emergency department, and the bypass group ( n = 115) who bypassed the emergency department and directly received PPCI. The data of all patients were collected and analyzed. Results There were no significant differences in baseline characteristics and PPCI related data (including percentage of thrombus aspiration catheter used, length or diameter of stents applied between two groups (all P ﹥ 0. 05) . The bypass group had shorter door-to-ballon ( D2B) than the control group [ (67. 7 ± 21. 5) min vs. (89. 4 ± 23. 6) min, P ﹤ 0. 001] . There were no significant differences in 30-days all-cause mortality, re-myocardial infacrtion and target ressel revascularization (TVR) between the two groups (P ﹥ 0. 05) . Total MACEs rate in the bypass group was lower than in the control group (10. 2% vs. 1. 7% , P = 0. 012) . Logistic regression analysis showed that age, diabetes, pain-to-door (PTD) time and CK peak value were the main influencing factors for 30-day MACEs rate of patients receiving PPCI ( P ﹤0. 05) . Conclusions Bypassing the emergency department can shorten D2B time and reduce 30-days MACEs post-PPCI, but reducing the total ischemic time will be more beneficial to patients with acute myocardial infarction.
