Objective To compare the effects of total intravenous anesthesia or Intravenous-in-halation combined anesthesia on intraoperative somatosensory evoked potential (SSEP)and motor evoked potential (MEP)in spinal surgery.Methods Sixty patients scheduled for spinal surgery under general anesthesia were divided randomly and equally into 2 groups.The anesthesia was maintained with TCI propofol (plasma target concentration 3.0-3.5 μg/ml)and 1% sevoflurane+propofol in group T or group I respectively.BIS was monitored and maintained at 40-50.SSEP and MEP was re-corded before induction of anaesthesia (T0 ),5 minutes after tracheal intubation (T1 ),during skin in-cision (T2 )and at the time of decompressing spinal canal (T3 ).Results The latency of P38 and N45 prolonged,and the amplitudes of P38 and N45 was significantly depressed at T1-T3 compared to those at T0 (P <0.05).No statistically significant differences in cortical SSEP amplitudes or latency was observed in each time point.There was no case who could not detect the wave of MEP intraoperative-ly in this study.Conclusion The data from these cases indicates that 1% sevoflurane can be used in conjunction with SSEP and MEP monitoring for some adult patients undergoing spinal surgery.

Objective: To compare the different therapeutic effects of acupuncture and Phenolphthalein for constipation due to intestinal qi stagnation. Methods:A total of 50 patients with constipation due to intestinal qi stagnation were randomly divided into an acupuncture group and a medication group by the random digital table, 25 cases in each group. The patients in the acupuncture group were treated by puncturing Gongsun (SP 4), Sanyinjiao (SP 6), Taichong (LR 3), Zusanli (ST 36), Shangjuxu (ST 37), Hegu (LI 4), Lieque (LU 7), and Tianshu (ST 25), once every day, and 7 d as one course, for continuous 3 courses; while the patients in the medication group were given Phenolphthalein, 7 d as one course, for continuous 3 courses. Compared the Cleveland clinic constipation score (CCS) between the two groups after one course, 3 courses and 3 months after the treatment, as well as the frequency of defecation within one week. Results:After one week of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significantly in the patients of the medication group than in those of the acupuncture group (P<0.01). After 3 weeks of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significant in the patients of the acupuncture group than in those of the medication group (P<0.05). Three months after the end of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significantly in the patients of the acupuncture group than in those of the medication group (P<0.05). Conclusion:Acupuncture and medication are effective in the treatment of constipation due to intestinal qi stagnation. Their short-term therapeutic effect is similar, but the long-term therapeutic effect is better in the acupuncture group than in the medication group.

Objective To investigate the effect of multidisciplinary intervenient on survival of patients with malignant tumor. Methods Six hundred and thirty-nine malignant tumor patients were randomly assigned to the intervenient and the control group. A total of 584 completed the follow-up study. The intervenient group received comprehensive treatment for 2 years,while the control group was in a process of self-rehabilitation. The 2-year survival rate was compared between the groups by using Cox proportional hazard model. Results The 2-year survival rate was 94. 74% (108/114) or 80. 67% (121/150) in II stage patients of the intervenient or control group, respectively ( P < 0. 01 ) . The 2-year survival rate was 88. 03% (163/177) or 82. 8% (184/222) in early and medium stage patients of the intervenient or control group,respectively(P <0. 01). Conclusion The multidisciplinary intervenient may help to improve the 2 year survival of early or moderate stage malignant tumors.

Objective: To observe the therapeutic efficacy of astragalus polysaccharide (APS) in combination with three-dimensional conformal radiotherapy (3D-CRT) for elderly patients with non-small cell lung cancer (NSCLC). Methods: A total of 80 elderly patients with I～IV stage NSCLC were randomly divided into two groups. The 40 patients in the therapeutic group received radiotherapy in combination with APS. The 40 patients in the control group received radiotherapy alone. Both groups received 3D-CRT with a total dose of 50～ 70Gy, 2.0Gy/fraction, once a day, 5 times per week. The patients in the therapeutic group were treated with radiotherapy combined with injection of APS (250mg in 5% glucose) or normal saline (500 mL) intravenously once a day until the end of radiotherapy. The short-term efficacy and patients' quality of life were evaluated. The T-lymphocyte subpopulation and peripheral blood leukocyte count were also measured after treatment. Results: The short-term effective rates of the therapeutic group and the control group were 87.5% and 72.5%, respectively, without significant difference between the two groups (P＞0.05). The decrease of peripheral blood leukocyte count after treatment in the control group was significant (P＜0.05). In the therapeutic group, the T-lymphocyte subsets CD8 and CD4/CD8 were improved after treatment, with a significant difference (P＜ 0.05). But in the control group, no significant changes in T-lymphocyte subsets CD8 and CD4/CD8 were observed after treatment (P＞0.05). Patients' quality of life in the therapeutic group was superior to that in the control group, with a significant difference (P＜0.05). Conclusion: APS in combination with 3D-CRT can reduce the side effects of radiation and improve the quality of life of elderly patients with NSCLC.

Objective To investigate the effects of virtual reality prism adaptation on visuospatial neglect in stroke patients.Methods Thirty stroke patients with visuospatial neglect were studied.The subjects were divided into atreatment group and a control group.The subjects in the treatment group were treated with virtual reality prism adaptation and routine rehabilitation interventions for 2 weeks,while those in the control group were treated with routine rehabilitation interventions only.All the patients performed a battery of spatial attention tests including line bisection,letter cancellation,clock drawing and the Attention Network Test at the beginning and after 2 weeks of treatment.Results The virtual reality prism adaptation training had significant positive effects on all the measures of visuospatial neglect.Pair-wise comparisons confirmed significant differences between the treatment and control groups after 2 weeks of treatment with regard to all of the measures.Conclusions Virtual reality prism adaptation treatzment combined with routine rehabilitation can be more effective than conventional measures alone in improving the visuospatial performance of stroke survivors.

Aim To investigate the antiarrhythmic mechanism of taurine-magnesium coordination com-pound on abnormal sodium current channel ( INa ) in-duced by hypoxia-reoxygenation in ventricular myocytes of rats. Methods Single ventricular myocytes were i-solated from each rat heart using enzymatic dissociation through Langendorff retrograde aortic perfusion. Whole-cell patch clamp was applied in voltage clamp mode to record INa both in normal ventricular myocytes and single ventricular myocytes of arrhythmia induced by hypoxia-reoxygenation. Results The peak density of INa was changed from ( 56. 89 ± 2. 07 ) pA/pF to (35. 05 ± 1. 52) pA/pF( n=6, P <0. 01 vs control) by hypoxia-reoxygenation with the INa I-V curve shifting upward. TMCC(200, 400 μmol·L-1)was able to re-store the reduction caused by H/R to (35. 78 ± 1. 95) pA/pF, (41. 52 ± 0. 86) pA/pF, (n=6,P <0. 01) and (48. 34 ± 0. 99) pA/pF(n=6,P<0. 01) respec-tively, but not at 100 μmol·L-1(n=6, P>0. 05), in a concentration-dependent manner, while amioda-rone restored it to (39. 44 ± 1. 24) pA/pF (n=6,P<0. 01 ) . Both high concentration of TMCC and amioda-rone could shift the I-V curve downward. In addition, TMCC and amiodarone could restore the INa inactivation curve and slow down its inactivation, whereas the acti-vation curves showed no significant differences among groups. Conclusion TMCC(200,400 μmol·L-1) could restore the H/R induced INa reduction and shift the I-V curve downward by inhibiting steady-state inac-tivation, which is suggested to be one of the mecha-nisms of the antiarrhythmic effects of TMCC in hypoxia-reoxygenation model.

Objective:To preliminarily study the characteristics of ventricular synchronicity in patients of idiopathic pulmonary arterial hypertension (IPAH) with different heart function.
Methods:Our research included in 2 groups:IPAH group, n=40 patients intermittently collected in our hospital from 2010-10 to 2014-12 and Control group, n=23 normal subjects from the same period of time. Tissue Doppler echocardiography was conducted to compare interventricular systolic and diastolic time to peak (Ts and Te), their differences (Te-Ts) and (Te-Ts) of left ventricle (LV), right ventricle (RV), interventricular septum (IVS) between 2 groups.
Results:Ts and Te of RV were longer than Ts and Te of LV and IVS in both groups, P<0.05. Compared with Control group, by heart function reducing, IPAH group showed different Ts and Te of LV and IVS, P<0.05 and Ts was gradually prolonged, Te was gradually shorter;while Te of RV became longer firs tand then became shorter thereafter. In IPAH group, the patients with heart function grade IV had the longer Ts of LV and IVS than those with heart functionII, III;the patients with heart function IV had the shorter Te of LV, RV and IVS than those with heart function II, III, all P<0.05. In IPAH group with different heart function, Te between RV-IVS and RV-LV were different from Control group, all P<0.05;Te between LV-IVS in heart function IV patients had the largest difference from Control group, P<0.05. Compared with Control group, IPAH group had gradually decreased Te-Ts of LV and IVS by heart function reducing asgrade II>III>IV, all differences had statistic meaning.
Conclusion:IPAH patients with different right heart function may have interventricular systolic and diastolic de-synchronicity;by reduced heart function, interventricular Te-Ts could be specifically shortened.
