Objective To explore the value of serum level of interleukin 6 (IL-6),tumor necrosis factor alpha (TNF-α) and high mobility group box-1 protein( HMGB1) in early assessment the severity and prognosis of acute pancreatitis (AP). Methods Thirty-three severe acute pancreatitis (SAP) patients and 38 mild acute pancreatitis (MAP) patients were selected as study objects;and 51healthy individuals were set as control group. Serum IL-6,TNF-α and HMGB1 concentrations were determined by enzyme-linked immunosorbent assay (ELISA),the association of them and the scores of Ranson,APACHE Ⅱ . Balthazar CT,serum biochemical parameters and prognosis was analyzed.Results The serum IL-6 levels of SAP group,MAP group and healthy control group were (553. 72±175.76) pg/ml,(265. 73±179. 95) pg/ml and (16. 43±3. 32) pg/ml;and there were statistical significance of these three groups (all P<0. 01). There was no significant difference of TNF-α in the three groups (all P>0. 05). The serum HMGB1 levels of SAP group,MAP group and healthy control group were (11. 48±6. 94)μg/L,(6. 13±5. 80)μg/L and (1. 82±0. 64)μg/L respectively,and there were statistical significant of these three groups (all P<0. 05). The correlation coefficient of serum HMGB1 with IL-6 and TNF-α were 0. 896 and 0. 724 (P<0. 01) respectively. The IL-6 level was positively correlated with the scores of Ranson,APACHE Ⅱ and Balthazar CT. The TNF-αconcentration was positively correlated with APACHE Ⅱ score,and the HMGB1 concentration positively correlated with scores of Ranson and Balthazar CT. The levels of IL-6,TNF-α and HMGB1were all positively correlated with the serum creatinine concentration. The IL-6 levels of patients with local and/or systemic complications were significantly higher than those without complications.Conclusion The serum levels of IL-6,TNF-α and HMGB1 are significantly correlated with the severity of pancreatitis,all of them take part in the development of acute renal insufficiency. The high level of serum IL-6 significantly correlated with complications.

Objective To assess the effect of QRS duration (QRSd) and cardiac function during right ventricular apex(RVA) pacing,right ventricular outflow tract (RVOT) pacing and right ventricular bifocal (RV-Bi) pacing. Methods Eight patients underwent RVA pacing,RVOT pacing and RV-Bi pacing during pacemaker implantation operation.The ejection fraction (EF),stroke index (SV),cardiac output(CO),QRS QRSd,QRS axis (QRSa) were measured after each pacing at the same pacing frequency. Results Compared with RVA pacing,the EF,SV and CO increased during RVOT pacing and RV-Bi pacing.The cardiac function of RV-Bi pacing was significantly increased (P

Objective To evaluate the effectiveness of biofeedback for anxiety patients by carrying out a Meta-analysis.Methods We searched CNKI,VIP,CBM(1989 to 2013) to identify relevant randomized-control trials applying biofeedback for anxiety patients.We used Review Management (RevMan) 5.0 software (provided by the Cochrane collaboration) to conduct Meta-analysis.Results We included 11 studies.Meta-analysis for the biofeedback group vs.the control group showed that biofeedback was significantly superior to control (SMD=-3.00,95%CI:-4.40~-1.61); Meta-analysis for the biofeedback plus drug group vs.drug group showed that biofeedback plus drug was significantly superior to drug (SMD=-1.33,95%CI:-1.82~-0.85).Conclusions We found evidence that biofeedback (applying alone or combined with drugs) is effective in improving anxiety symptom.But all the studies had methodological limitations,our conclusion needs further studies with strict design,high quality and consistent assessment tools to be expounded and proven.

Objective To investigate the localization,zone and activation intensity of olfactory center in young versus elderly healthy volunteers by functional magnetic resonance imaging (BOLD-fMRI),so as to elucidate the effect of age on olfactory center in healthy population.Methods Thirteen right-handed healthy adult volunteers were recruited and divided into two groups:young group (5 males and 3 females,mean aged 23 years) and elderly group (2 males and 3 females,mean aged 69.2 years).The olfactory stimulus was r-undecalactone,and it was given according to a block design.The fMRI detection was performed on Philips Achieva 3.0 T MR scanner,and data of BOLE-fMRI was processed and analyzed to get cerebration image by using SPM2.Results In groupaveraged maps,both young and elderly group showed significant olfactory activation in right parahippocampal gyrus,left hippocampal sulcus,right and left superior temporal gyrus,etc,subcortical activation in right thalamus,dorsal pons,and cerebellum activation in cerebellar vermis.Activations in right inferior frontal gyrus,right middle frontal gyrus,right medial occipito-temporal gyrus and right fimbria of hippocampus were observed only in young group,while activation in bilateral middle temporal gyrus was observed only in elderly group.Activation area was apparently smaller and activation degree was lower in elderly group than in young group.Activation intensity in right superior parietal lobule and bilateral superior temporal gyri was higher in male group than in female group (t=13.7,6.08,5.36,respectively,all P<0.001).Conclusions The intensity of activation in olfactory center is lower in the elderly than in the young,and absence of part of the active regions is found in the elderly,which demonstrates the regression of olfactory center in the elderly.The olfactory center shows right-predominant activation,and olfactory activation intensity in some cortical regions is higher in males than in females.

Objective To observe the therapeutic effect of electroacupuncture combined with rehabilitation exercises on swallowing function and cerebral perfusion in dysphagic stroke patients.Methods Sixty-two stroke pa- tients with dysphagia were randomly divided into a treatment group(n=32)and a control group(n=30).The treat- ment group received electroacupunture,rehabilitation exercise and conventional medical treatment,while the control group received only rehabilitation exercise and conventional medical treatment.They were treated once a day,6 times a week for 4 weeks.Water drinking test,stethocatharsis scores and swallowing fluorography were used to assess the swallowing function before and after treatment.Single photon emission computed tomography(SPECT)was also em- ployed to observe the status of cerebral perfusion before and after treatment.Results It was shown that the swallo- wing function and cerebral perfusion in the treatment group were significantly better than the control group after treat- ment.The effective rate in the treatment group was 96.88% while that of the control group was 66.67%.Conclu- sion Electroacupuncture combined with rehabilitation exercises is effective in treating the dysphagic stroke patients, and can significantly improve the brain perfusion of these patients.
