ObjectiveTo investigate the influence on negative emotion of ICU patient's relatives by comprehensive needs intervention.Methods 100 ICU patient's relatives were randomly divided into intervention group and control group,50 cases per group.Patients in intervention group were given comprehensive needs interventions for two weeks,then were tested by self-rating anxiety scale(SAS),self-rating depression scale(SDS) and symptom checklist 90 (SCL-90),and their negative emotion were compared.ResultsExcept for interpersonal relationship factor (P＞ 0.05 ),the other SCL-90 factorial scores of ICU patient's relative were all significantly higher than the national norm before intervention(P ＜ 0.01 ～0.05 ).Anxiety and depression rates in two groups were 64％ and 53％ respectively,SDS standard scores were 49.62 ± 9.18 and 49.70 ± 9.73,SAS scores were 40.08± 11.93 and 40.04 ± 11.76,and they were all significantly higher than normal norm.After intervention,SAS,SDS standard scores and SCL-90 factors of intervention group were significantly decreased,and were superior than control group,and there were statistical difference (P＜ 0.01 ～ 0.05 ).ConclusionThere are so much psychological diseases with the relatives of ICU patients,especially anxiety and depression.

BACKGROUND:In recent years, a single-door laminoplasty for cervical spondylotic myelopathy was performed in the Department of Orthopedics, the First Affiliated Hospital of Zhengzhou University. This surgery achieved spinal decompression while remaining the important structure of cervical vertebra.
OBJECTIVE:To comparatively analyze the therapeutic effects of minimal y invasive cervical laminoplasty and single-door laminoplasty on cervical spondylotic myelopathy.
METHODS:A total of 78 cases of cervical spondylotic myelopathy were randomly divided into two groups, which respectively received minimal y invasive cervical laminoplasty and single-door laminoplasty.
RESULTS AND CONCLUSION:Al cases were fol owed-up for 3-36 months. No significant difference in excellent and good rate of Japanese Orthopaedic Association score was detected between the two groups in final fol ow-up (P>0.05). The apparent rate of axial symptoms was significantly lower in the minimal y invasive cervical laminoplasty group than that in the single-door laminoplasty group after treatment (P<0.05). Cervical curvature loss was significantly lower in the minimal y invasive cervical laminoplasty group than that in the single-door laminoplasty group (P<0.05). In final fol ow-up, in the minimal y invasive cervical laminoplasty group, two titanium screws of one patient were slightly loose, and no abnormal symptom was observed. In the single-door laminoplasty group, hinge breakage was visible in six patients. The broken vertebral plate was excised. Artificial spinal dura mater was coated on the surface of spinal cord for protection. Results suggested that the effect of two surgical methods in promoting functional recovery of spinal cord is identical. However, complications in the minimal y invasive cervical laminoplasty group are further fewer than those in the single-door laminoplasty group.

The paper reported an investigation of the pharmacokinetics of SN-38 (7-ethyl-10-hydroxy-camptothecin) in rats and the tissue distribution in mice after injection of irinotecan hydrochloride nanoparticles (CPT-11) via tail veins. An LC-MS/MS method was established to determine the concentrations of SN-38 in whole blood of rats and in different tissues of mice. The pharmacokinetics and tissue distribution of SN-38 were compared after the intravenous injection of CPT-11 NPs and CPT-11 solution. Compared with irinotecan solution, the elimination half-life of SN-38 was prolonged from 2.17 h to 2.67 h after the intravenous injection of CPT-11 NPs, but its AUC had little change. After the injection of CPT-11 NPs in mice, over time, the concentrations of CPT-11-metabolized SN-38 in CPT-11 NPs were significantly higher in the whole blood, colon and lungs than those in CPT-11 solution, followed by in the spleen and liver, but those in the heart and brain had no change. However, the amount of SN-38 in the kidneys was reduced with time. CPT-11 NPs could prolong SN-38's (one of its metabolites) blood circulation time in rats and significantly increased the concentration of CPT-11-metabolized SN-38 in the whole blood, colon and lungs of mice. CPT-11 NPs made SN-38 efficiently target-bind to the colon and lungs of mice.

Objective To discuss the psychological behavior intervention methods on reducing the violence behavior of schizophrenia patients. Methods 120 schizophrenia patients were admitted from January to December, 2007 and randomly assigned into the behavior intervention group (group A), the psy-chological support group (group B), the health education group (group C) and the control group (group D) with 30 cases in each group. Group A received routine nursing plus behavior intervention, group B was giv-en routine nursing plus psychological support, group C adopted routine nursing plus health education, group D only received routine nursing. The intervention effect was evaluated with MOAS and the relapse rate of violence behavior went through statistics. Results After intervention, the scores of MOAS decreased sig-nificantly in group A, B, C and D compared with those before intervention. The reduction of MOAS scores in group A, B and C was significantly higher than that of group D, with the highest reduction score in group A and group B and C followed subsequently. The relapse rates of the violence behavior in group A, B and C were significantly lower than those of group D. Conclusions Routine nursing, health education, psycho-logical support and behavior intervention can all reduce and decrease the violence behavior and the inci-dence of the violence behavior, among which behavior intervention proves to be the most effective, and psy-chological support and health education go subsequently.

Aim To study the inhibitory effect of ginkgolide B (BN52021) on the PAF induced changes of chemotaxis of murine peritoneal macrophages and the related polymerization of F-actin.Methods Chemotaxis assays were performed using a modified 48-well Boyden chamber. Actin polymerization of murine peritoneal macrophages was analyzed by flow cytometry using a specific fluorescent stain. Results Peritoneal macrophages significantly migrated toward platelet-activating factor(PAF) through a micropore filter; however, in the presence of PAF receptor antagonist BN52021 (0. 01the actin polymerization of murine peritoneal macrophages induced by PAF in the presence of Ca2+ , but not in Ca2+ -free medium. Conclusion The results suggested that preventing polymerization of F-actin may be a pathway by BN52021 to inhibit the chemotaxis of macrophages, and this effect seems to be Ca2+dependent. The data further indicated that inhibition of PAF induced macrophage chemotaxis is an important mechanism underlying the anti-inflammatory action of BN52021.
