BACKGROUND: The recent researches show that there are various kinds of autoantibodies in epilepsy patients such as anti-nuclear antibodies, anticardiolipin antibodies,anti-?2 glucoprotein antibodies and anti-glutamic acid decarboxylase antibodies,which indicate that some types of epilepsy are mediated by autoimmune mechanism.OBJECTIVE: To detect the level of anti-glutamic acid receptor (GluR1)antibody in epilepsy children.DESIGN: A controlled trial.SETTING: Medical College of Dalian University, General Hospital of Jilin Chemistry Group and Sanchong University, Japan.PARTICIPANTS: Totally 56 cases of epilepsy children were from Maternal and Child Health in Qingdao City including 30 males and 26 females and aged from 3 months to 13 years.While 48 health examinees and 12 patients with brain tumor from General Hospital of Jilin Chemistry Group were taken as controls, including 38 males and 12 females and aged from 6months to 17 years.Their guardians were all informed of the detection index and consented to join the study.METHODS: Polystyrene plates were coated with GluR1 polypeptide antigen,and optimal conditions of enzyme linked immunosorbent assay (ELISA) for GluRI antibody was ascertained with chessboard titration.MAIN OUTCOME MEASURES: The GluR1 antibody level was detected with ELISA.RESULTS:The concentration of coating GluR1 polypeptide antigen was20 mg/L; The dilution of serum and horseradish peroxidase sheep anti-hu-man (HRP-SaH) IgG were 1:50 and 1:1 500 respectively. Intra-assay andinter-assay coefficientof variability were 4.48％-8.80％ and 11.18％-16.60％ respectively; The specific absorption test demonstrated that the ab-sorbance value of positive serum decreased 2.4 times after absorption ofGluR1 polypeptide compared with that before absorption.There was obvi-ous higher positive rate of GluR1 antibody in serum of epilepsy childrenthan control group (40％, 5％, P＜0.01).CONCLUSION:①ELISA is specific and stable for GluR1 antibody in serum. ②There is the possible autoimmune response of GluR1 antibody in serum of epilepsy children.

Objective To observe the anal exhaust effect in patients treated with warm water foot bath after laparoscopic surgery.Methods 90 cases after laparoscopic surgery including renal cancer , renal cysts, epinephrine-tumor patients were randomly divided into A , B and C group.Nursing measures were given at 6 hours after operation. A group were treated with warm water feet bath ; B group received abdominal ring massage ; And C group were control group.Time of anal exhaust postoperatively was observed among the 3 groups.Results Anal exhaust time after oper-ation in A group was average (24.34 ±0.28) hours, which was significantly shorter than in B group (33.07 ±0.18) h and C group (37.90 ±0.19) h (p <0.01).Conclusion Warm water foot bath can promote the anal exsufflation rapidly, effectively after laparoscopic surgery in Urology patients , and has great significance helpful to early recovery .

To explore the role of mechanosensitive potassium channel TREK-1, Western blot analysis was used to investigate the expression changes of TREK-1 in left ventricle in acute mechanically stretched heart. Forty Wistar rats were randomly divided into 8 groups (n=5 in each group), subject to single Langendorff perfusion for 0, 30, 60, 120 min and acute mechanical stretch for 0, 30, 60, 120 min respectively. With Langendorff apparatus, an acute mechanically stretched heart model was established. There was no significant difference in the expression of TREK-1 among single Langendorff perfusion groups (P>0.05). As compared to non-stretched Langendorff-perfused heart, only the expression of TREK-1 in acute mechanically stretched heart (120 min) was greatly increased (P<0.05). This result suggested that some course of mechanical stretch could up-regulate the expression of TREK-1 in left ventricle. TREK-1 might play an important role in mechanoelectric feedback, so it could reduce the occurrence of arrhythmia that was induced by extra mechanical stretch.

Objective To establish an early,simple and rapid colloidal gold strip method for the detection of IgM against hantavirus nucleocapsid protein in patients with hemorrhagic fever with renal syndrome(HFRS).Methods Purified recombinant Hantavirus nucleoprotein(rNP)was labeled by colloidal gold particles and then sprayed and fixed on fiberglass membrane as the combination pad.Anti-Human IgM(μ-chain specific)antibody produced in goat was fixed in the detection area,and mouse antihantavirus antibody was fixed in the quality control area.Both of them were on nitrocellous membrane strip in tandem.Together with a specimen pad ahead.The conbination pad and the nitrocellous membrane were assembled into a test strip.The colloidal gold strip assay was compared with ELISA for evaluation of specificity and sensitivity.Results The colloidal gold strip tests showed positive in the serum samples from 50 cases of HFRS which was clinically diagnosed and then verified by ELISA within 10-15 minutes.Whereas 30 serum samples of healthy donors have tested negative.Conclusions Our new colloidal gold immunochromatographic test strip method was well concordant with the ELISA assay,but the former was more raoid and simole.It could be used primary medical services.

Objective To explore the value of dynamic monitoring of the neutrophils/lymphocyte ratio ( NLR ) in peripheral blood for the prognosis of patients with bloodstream infection ( BSI ). Methods A retrospective study was conducted. 205 patients who were≥18 years old, their length of hospital stay>24 hours, and they were treated in the China-Japanese Friendship Hospital from January 2013 to October 2014 were enrolled. According to the 28-day survival, the patients were divided into survival group ( n=160 ) and death group ( n=45 ). The white blood cell ( WBC ), neutrophils count ( NEU ), neutrophils ratio ( Neut%), lymphocyte count ( LYM ), lymphocyte ratio ( Lym%), and NLR in peripheral blood were recorded at 1, 3, 7 days after admission. Receiver-operating characteristic curve ( ROC ) was plotted for evaluating the value of these factors on the 28-day prognosis, and logistic regression analysis was used to evaluate the risk factors for predicting the outcome. Results ①On the 1st day, WBC, NEU, Neut%, NLR, and procalcitonin ( PCT ) in the death group were significantly higher than those in the survival group [ WBC (×109/L ):15.28±8.23 vs. 11.58±6.55, NEU (×109/L ):13.34±7.53 vs. 10.03±5.31, Neut%:0.886±0.076 vs. 0.845±0.102, NLR:21.20 ( 13.10, 28.80 ) vs. 12.08 ( 6.81, 20.47 ), PCT (μg/L ):3.13 ( 0.85, 10.12 ) vs. 1.34 ( 0.36, 5.81 ), P<0.05 or P<0.01 ], while hemoglobin ( Hb ), platelet count ( PLT ), albumin ( ALB ) content were significantly lower than those of the survival group [ Hb ( g/L ):86.09±19.83 vs. 107.89±22.82, PLT (×109/L ):157.51±117.81 vs. 195.44±97.28, ALB ( g/L ):24.11±6.94 vs. 31.99±6.89, P<0.05 or P<0.01 ]. On the 3rd day and 7th day, WBC, NEU and NLR in the death group were significantly higher than those of the survival group [ WBC (×109/L ):16.61±10.25 vs. 8.91±4.93, 16.05±9.46 vs. 8.79±4.45; NEU (×109/L ): 14.15±9.98 vs. 6.97±4.64, 14.36±9.03 vs. 6.59±4.07; NLR: 24.13 ( 8.49, 38.26 ) vs. 5.52 ( 3.58, 8.87 ), 17.74 ( 10.74, 32.85 ) vs. 4.35 ( 2.78, 7.27 ), all P<0.01 ], and the LYM and Lym%were significantly lower than those in the survival group [ LYM (×109/L ):0.61 ( 0.38, 1.04 ) vs. 1.05 ( 0.78, 1.43 ), 0.69 ( 0.35, 0.92 ) vs. 1.37 ( 0.93, 1.76 );Lym%:0.039 ( 0.024, 0.101 ) vs. 0.135 ( 0.094, 0.186 ), 0.056 ( 0.033, 0.082 ) vs. 0.170 ( 0.108, 0.237 ), all P<0.01 ].②It was shown by ROC curve that the maximum area under the ROC curve ( AUC ) of WBC, NEU, Neut%, LYM, Lym%, and NLR about prognosis of BSI were observed on 7 days ( 0.777, 0.819, 0.905, 0.755, 0.880, 0.887 ). Based on Neut%>0.855 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 78.8%, specificity 89.1%, respectively. When Lym%<0.088 on the 7th day as a predictor of cut-off value of death on 28 days, the sensitivity was 89.5%, and specificity was 83.9%. When NLR>10.34 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 81.8%, and specificity was 91.0%.③Survival analysis showed that the 28-day survival rate in the patients with 7-day NLR<10.34 was significantly higher than that in those with 7-day NLR>10.34 ( 95.0%vs. 34.1%,χ2=82.650, P=0.000 ).④It was shown by multi-factor logistic regression analysis that the levels of 1-day Hb and 7-day NLR were the independent prognostic predictors of 28-day mortality [ Hb: odds ratio ( OR ) = 0.946, 95% confidence interval ( 95%CI ) = 0.913-0.981, P = 0.003; 7-day NLR:OR=34.941, 95%CI=8.728-139.884, P=0.000 ]. Conclusions The trend of changes in NEU, LYM and NLR as shown by repeated routine blood examinations contributes to prediction of the outcome of patients with BSI. The levels of 1-day Hb and 7-day NLR are the independent prognostic predictors for 28-day mortality.

Objective To investigate the dynamic characteristic of molecular epidemiology of group A Rotavirus (RV) by analyzing viral genotypes,disease seasonality,and the patients' age distribution,so that to provide theoretical basis for preyention and control of RV diarrhea in children.MethodsA total of 380 RV antigen positive samples were selected from 5176 stool specimens collected from ＜5 year-old patients with acute diarrhea who were admitted to Children's Hospital of Fudan University during January 2006 to December 2008. Multiplex nested reverse transcription polymerase chain reaction (RT-PCR) was used to analyze the RV genotypes.ResultsDuring 2006-2008,the incidence of RV related diarrhea peaked from October to December and about 96.8％ of all RV episodes occurred in patients younger than 3 years old,The predominant genotype was G3 which accounted for 58.4％ (222/380),G9 was an emerging genotype with the prevalence rate as high as 10.8％ (41/380).G1 and G2 types were rarely found during the three years.Infections with both G3 and G9 were the major mixed genotype G infection. Genotype P [8] was predominant with the prevalence rates of 64.6％ (53/82) and 46.8％ (58/124) in 2006 and 2008,respectively,whereasgenotype P[4] was predominant in 2007 (38,5％,67/174).P[6] and P[9] were found as minor types.The major mixed genotype P infection were genotype P[4] and P[8]. The proportion of undetermined genotype G and genotype P strains tended to increasing during 2006-2008.Genotype P [8]G3 was the major RV strain (20.5％) in Shanghai during 2006-2008 and the other prevalent genotypes included P[4]G3 and P[m]G3.Conclusion The infection of group A RV in Shanghai presents some new molecular epidemiology characteristics during 2006-2008,such as switch of predominant genotypes and diversification of prevalent genotypes.
