BACKGROUND: Radiofrequency catheter ablation (RFCA) in dog triggers myocardial nerve sprouting and sympathetic hyperinnevation. It is possible that RFCA in humans has the same effect. Nerve growth factor (NGF) is a neurons nurture that supports the survival and differentiation of sympathetic neurons and enhances target innervation. Therefore, it is hypothetic that RFCA can increases plasma NGF concentration in humans.OBJECTIVE: To test the hypothesis that RFCA increases plasma NGF concentration in humans.DESIGN: Self-control experiment.SETTING: Department of Cardiology, Tangdu Hospital, the Fourth Military Medical University of Chinese PLA.PARTICIPANTS: Forty-three patients were selected from the Cardiological Department of Tangdu Hospital, the Fourth Military Medical University of Chinese PLA from January to June 2005, including atrioventricular nodal reentrant tachycardia (AVNRT) (n=18), right-sided accessory pathways (RSAP) (n=13) and left-sided accessory pathways (LSAP) (n=12), 20 males and 23 females, ages 28-65 years, all agreed to participate in the study voluntarily.METHODS: Blood samples were obtained from the peripheral veins before ablation and at 6 hours, 1, 3, 5, 7 days after ablation. The plasma concentration of NGF was determined with enzyme-linked immunosorbent assay (ELISA).MAIN OUTCOME MEASURES: The plasma concentration of NGF was determined with ELISA before RFCA and at 6 hours, 1, 3, 5, 7 days after RFCA in each patient.RESULTS: Total 43 patients who were referred for ablation therapy for AVNRT, RSAP and LSAP were involved in the result analysis without loss. Plasma NGF increased at 6 hours after RFCA. Increased NGF continued to 7 days in the RFCA treated patients. The plasma NGF concentrations at 6 hours, 1, 3, 5, 7 days after RFCA in AVNRT, RSAP and LSAP ablations treated patients were (29.72±7.04), (30.94±5.68),(31.39 ±4.92), (31.06 ±4.56), (29.11 ±4.59), (31.77 ±6.25), (30.69 ±5.10),(31.46±4.96), (30.15±4.01), (30.43±3.14), (31.42±6.75), (31.00±5.20),(32.08±4.62), (30.67±3.71), (29.27±2.75) μg/L, respectively, and all more than that before RFCA [(14.89±2.84), (15.00±2.71), (15.51±2.75) μg/L, P ＜ 0.01]. However, there were no significant differences in the NGF levels at 6 hours, 1, 3, 5 and 7 days after RFCA (P ＞ 0.05). The plasma NGF concentration was not significant different among AVNRT, RSAP and LSAP ablation patients at any given time (P ＞ 0.05). The number of RFCA applications, the procedure time and the total energy have no correlation with NGF concentration at any given time instance.CONCLUSION: RFCA increases plasma NGF concentration in humans and lasts for at least 7 days. The number of RFCA applications, the procedure time and the total energy have no correlation with NGF concentration at any given time instance.

Objective To observe the effect of ligustrazine injection combined with chemotherapy on common immunological parameters in patients with advanced hepatocellular carcinoma.Methods Eighty cases diagnosed with advanced hepatocellular carcinoma from January 2013 to January 2015 in the hospital were randomly divided into observation group and control group, 40 patients in each group.The control group received only conventional treatment of chemotherapy and observation group received ligustrazine injection on the basis of control group.The levels of interleukin-1 (IL-1), IL-4 and transforming growth factor beta ( TGF-β) wwere compared based on the record between two groups pre-and post-treatment.Results There were no significant differences between two groups in IL-1,IL-4 and TGF-βlevels pre-treatment.After treatment, the IL-1, IL-4 and TGF-βlevels in observation group were lower than those in control group [(41.4 ±11.8)vs (76.0 ±12.2)ng/L,(118.5 ±39.9)vs(223.0 ±47.3)ng/L,(6.7 ±3.2)vs(11.7 ± 2.6)ng/mL, respectively, all P<0.05].Conclusion Ligustrazine injection combined with chemotherapy has an exact effect on improving the immunological parameters associated with advanced hepatocellular carcinoma without significantly increasing side effects, it is worthy of further research and application.

Objective Both underuse and overuse of anticoagulant therapy may lead to severe adverse effects. Emerging portable monitering devices, which provides reliable and accurate measurements, were reported to be potential alternatives to tra-ditional monitering recta-analysis regimens. This study was intended to evaluate the effects of serf-monitoring or serf-management (self-testing and serf-dosing) of anticoagulant as compared with that of traditional monitoring. Methods Relevant trials reported before October 2008 were identified in a number of electronic database and analyzed with software RevMan 4.2. The primary out-comes included death from any cause, major bleeding event, thromboembolic event and the proportion of patients whose interna-tional normalized ratio (INR) were within the therapeutic range. Results Seventeen RCT of serf-monitoring were identified.Pooled estimates revealed significant reductions in the thromboembolic events (odds ratio 0.46, 95% CI0.33 -0.64), all-cause mortality (0.61,0.40 -0.93), and major haemorrhage (0.80, 0.58 - 1.10) with self-monitoring as comparing with traditional monitoring. No difference was noted in minor haemorrhage. 15 trials reported improvements in the mean proportion of patients whose INR were within target range. Conclusion Self-management regimen is superior to traditional monitoring in the outcomes of oral anticoagulation. Patients capable of self-monitoring and serf-adjusting have fewer thromboembolic events and lower mortali-ty than those undergoing self-monitoring alone. However, self-monitoring requires education and training for patients.

Objective：To explore the effect of group psychological service on mental health of the children left behind in rural areas.Methods：Totally 222 children left behind in rural areas were selected randomly and divided into intervention group and control group.The intervention group accepted 8 times of group psychological service.The Eysenck Personality Questionnaire(EPQ),Center for Epidemiological Studies of Depression scale for Children(CES-DC),Rutter Children's Behavior questionnaire for completion by teacher,Piers-Harris Children `s Self-concept Scale(PHCSS)were used in both groups to evaluate the effect at baseline,the end of the 7th intervention,and 6 months after the end of the intervention.Results：After intervention,the intervention group got lower scores than control group in EPQ-N [(8.2±5.8)vs.(10.2±6.1),P<0.05]in the first retest,and in CES-DC [(15.9±7.3)vs.(18.8±7.7),P<0.05]in the second retest.The group gained higher scores in anxietyand happy and satisfaction factors of PHCSS [(6.6±3.4)vs.(5.6±2.7),(6.5±1.9)vs.(5.7±1.8);Ps<0.05]. Conclusion：Group psychological service are effective to children left behind in rural areas with depression emotion and had a role in children's personality remodeling.

BACKGROUND: The concern over the use of electroencephalogram (EEG)diagnosis and biofeedback training as a viable option for children with attention deficit hyperactivity disorder(ADHD) has grown gradually.OBJECTIVE: To evaluate the diagnostic accuracy and therapeutic efficacy of A620 EEG system to ADHD children.DESIGN: Prospective observation and comparative study on ADHD children.SETTING: Psychological department of a municipal hospital.PARTICIPANTS: From October 2003 to May 2004, 113 outpatient children in Psychology Hyperactivity Department of the Central Hospital of Anshan City were selected. Inclusion criteria: 6 to 14-year-old outpatient children in Hyperactivity Department. Exclusion criteria: nervous system organic diseases, pervasive developmental disorder(PDD), mental retardation, epilepsy, psychotic disorder, acoustical and visual abnormalities,etc. Of all the ADHD children, 88 were male and 25 were female, with the mean age of(10 ± 3) years.METHODS: A620 EEG system was applied to examine the 113 participants. According to the Diagnostic Criteria for ADHD in Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-Ⅳ), published by American Psychiatry Association, ADHD children were diagnosed and then the EEG diagnostic accuracy and specificity were calculated. The System was also used for biofeedback treatment on 27 ADHD children. Fluctuation of EEG θ/β value was measured both before and after treatment, and the change of hyperactivity index was investigated by Conners Parent Symptom Questionnaire as well.MAIN OUTCOME MEASURES: EEG θ/β value, Conners index of hyperactivity (CIH).RESULTS: The diagnostic sensitivity of EEG on ADHD was 83.58%, and the specificity of it was 82.61%; EEB θ/β value of post-treatment was 8.26 ±4.05, which decreased significantly compared with pre-treatment value (12.38 ± 7.96) ( t = 2. 39, P ＜ 0.05); CIH was also dramatically declined from(24. 73 ± 10. 96) (pre-treatment) to( 12.05 ± 8.63)(post-treatment) ( t= 4.72, P ＜ 0. 01 ).CONCLUSION: EEG can be used as an accessory method in ADHD diagnosis due to its high sensitivity and specificity. Abnormalities of brainwave and hyperactivities of ADHD patients can be greatly ameliorated by EEGbiofeedback treatment.
