Objective To investigate the attentional network in patients with temporal lobe epilepsy(TLE) and the disease-related factors. Methods Fity-four patients with TLE and 40 controls were enrolled in our hospital from January 2007 to December 2008.The computerized ANT software was used for evaluating the attentional network efficiency and the clinical date of the patients with TLE were recorded. Logistic regression was used to identify the risk factors of attentional network efficiency. Results The mean reaction time(TLE:688.2±138.1 ms;Control:625.1±100.1 ms, t=2.06, P <0.05)and executive control network efficiency (TLE:155.7±57.0 ms;Control:108.0±33.8 ms, t=4.62, P <0.01) of the TLE group were lower than the healthy control group. The efficiency of alerting network and orienting network between the two groups were no significant difference. Logistic regression analysis showed that the positive epileptiform activity was an independent risk factor of the attentional impairment(95% CI : 1.03～42.33, OR =6.603, P =0.043). Conclusions The ANT demonstrate that patients with TLE may accompany with attentional executive control network efficiency impairment. Epileptiform discharge may cause attentional executive network efficiency impairment.

BACKGROUND: Some studies in vitro have reported that there are CD30 positive T cells in immunological response of allogenic transplantation.OBJECTIVE: To detect the relationship between the level of serum CD30 (sCD30) and clinical rejection in the patients with or without kidney transplantation, and analyze the importance of sCD30 in the estimation of immune state, monitor of acute rejection, and judgment of prognosis. DESIGN, TIME AND SETTING: Clinical case analysis study was performed at Jiangsu People's Hospital between April 2004 and March 2007. PARTICIPANTS: 153 kidney transplantation cases comprising 103 males and 50 females, averagely aged 37 years. METHODS: 3 mL peripheral blood was obtained from recipients before transplantation (without immunosuppressive agent) and at 0, 1, 3, 5, 7, 14, 21, and 28 days. Serum was isolated from obtained blood and placed at -20 ℃. Soluble CD30 levels were detected using CD30 cytokine ELISA kit supplied by BenderMedSystems. MAIN OUTCOME MEASURE: The relation between the soluble CD30 levels and rejection prior to and following transplantation.RESULTS: There was a significant relation in the sCD30 level between the patients with (n=17) and without acute rejection (n=136). The CD30 levels were 113.2 U/mL in the rejection group and 83.2 U/mL in the non-injection group (P < 0.01). No significant difference was determined between both groups in 5 days following surgery (P > 0.05). Significant difference were detected between both groups from 5 days following surgery (P < 0.01). There was no relation between the soluble CD30 level and the time of rejection and release after kidney transplantation (P > 0.05). Receiver operating characteristic (ROC) curve demonstrated that soluble CD30 levels on day 5 post-transplantation could predict acute rejection (area under ROC curve: 0.850). Meanwhile, 100 U/mL was the optimal operational cut-off level to predict rejection (specificity: 85.0%; sensitivity: 83.6%). The patients with positive of soluble CD30 level showed a lower survival rate than those with negative CD30 level (P < 0.01). CONCLUSION: The soluble CD30 levels contributed to predictive the acute rejection and prognosis of kidney transplantation.

Objective To evaluate the safety of anesthesia endoscopic retrograde cholangio pancreatography (ERCP) under general anesthesia.Methods From January 1st,2008 to June 30th,2016,patients underwent ERCP under general anesthesia were enrolled as anesthesia group and from January 1st,2005 to December 31st,2007,patients accepted ERCP without anesthesia were enrolled as control group.Chi-square test was performed to analyze disease composition,conditions during operation,success rate of operation and complications in these two groups.Results A total of 14 724 patients with ERCP under general anesthesia and 2 102 patients received ERCP without anesthesia were enrolled.In 14 724 patients with ERCP under general anesthesia,1 799 cases had malignant biliary and pancreatic diseases and 12 925 cases with biliary and pancreatic diseases.During the operation,transient hypoxemia occurred in 441 cases (3.00％) and relieved by increasing oxygen flow,lower anesthetic dose or lifting lower jaw.The success rate of ERCP in the anesthesia group (98.41 ％,14 490/14 724) was higher than that in the control group (97.34％,2 046/2 102),and the difference was statistically significant (x2 =11.500,P=0.001).The incidence rate of post-ERCP pancreatitis in the anesthesia group was 2.35％ (346/14 724),which was lower than that in the control group (3.85％,81/2 102),and the difference was statistically significant (x2 =16.813,P＜0.01).Conclusion ERCP under general anesthesia is safe,which could increase the success rate of operation and reduce the incidence rate of post-ERCP pancreatitis.
