Aim To study the anti-inflammatory effects and mechanisms of SBM isolated from Scutellariae radix by high hydrostatic pressure.Methods The effect of SBM on ConA-induced splenocyte proliferation and LPS-induced IL-1? production from peritoneal macrophage was studied in vitro,and the therapeutic effects of SBM on adjuvant-induced arthritis,formalin-induced paw oedema and acetic acid-induced vascular permeability were also investigated.Results SBM(31.25～500 mg?L-1)significantly inhibited ConA-induced splenocyte proliferation,IL-1? production from peritoneal macrophages in vitro.SBM 20 mg?kg-1 inhibited primary and secondary inflammatory reaction,decreased the elevated level of IL-1? released from peritoneal macrophages,inhibited splenocyte proliferation in adjuvant-induced arthritis in rats.Moreover,SBM inhibited formalin-induced paw oedema and acetic acid-induced vascular permeability.Conclusions SBM could inhibit inflammatory reaction.Its mechanisms might be related to the suppression of immune function and inhibition on proinflammatory cytokines production.

Aim To study the anti-inflammatory effects and mechanisms of SBM isolated from Scutellariae radix by high hydrostatic pressure.Methods The effect of SBM on ConA-induced splenocyte proliferation,LPS-induced PGE2 production and protein expression of COX-2 were studied in vitro,and the therapeutic effects of SBM on carragineen-induced paw oedema and acetic acid-induced twisting reaction were also investigated.Results SBM(15.63～250) mg?L-1 significantly inhibited LPS-induced PGE2 production and COX-2 enzyme activity in peritoneal macrophages in mice.SBM(125 mg?L-1)also inhibited ConA-induced protein phosphorylation of p38 MAP kinase and LPS-induced COX-2 protein expression.SBM(10,20 mg?kg-1)inhibited carragineen-induced paw oedema and acetic acid-induced twisting reaction.Conclusion SBM can inhibit inflammatory reaction.Its mechanisms may be related to the suppression of inflammatory medium production.

OBJECTIVE: To investigate the feasibility and efficacy of CO2 laser assisted posterior cordotomy for patients with bilateral paralysis of the vocal cord. METHOD: Twenty-one patients with bilateral paralysis of the vocal cord underwent CO2 laser assisted posterior cordotomy in our hospital from Jul. 2009 to Jun. 2015. The causes of the bilateral paralysis of the vocal cord were thyroidectomy in 15 cases, cervical trauma in 2 cases, resection of pituitary tumor in 1 case, inflammation in 1 case and without cause in 2 cases. Ten patients underwent tracheotomy before the operation; 9 patients underwent tracheotomy after the operation; 2 cases without tracheotomy. RESULT: The tracheotomy tube was plugged next day after posterior cordotomy. Lots of patients were breathing well without any effort. A few patients were breathing hard, so the tracheotomy tube was plugged discontinuously. Seventeen patients were decannulated 1 year after operation. Two patients were failed to decannulated. The patients were followed up for 3 months 6 years after operation, and all of them were breathing well. CONCLUSION Our limited experience showed that CO2 laser assisted posterior cordotomyis an effective and reliable surgical procedure for patients with bilateral paralysis of the vocal cord.

Information department in hospitals shoulders the tasks of construction,operation,maintenance and super-vision of hospital information system ( HIS) . The work load increases with the update of HIS. The key issues con-cerned by the chief of HIS include the over planning of resources,optimizing the allocation of techniques,enforcing the means of management, improving the level of service and the efficiency of support. The principles for the design of performance appraisal program and the specific appraisal indicators in Information Department of Chinese PLA Second Artillery Forces were thus described in this paper in an attempt to provide reference for the information management in other hospitals.

Objective To explore the diagnostic value of multi-slice computer tomography (MSCT) in cause and location of agnogenic intestinal obstruction. Methods With light speed 16 multiple slice spiral-CT, 68 patients clinically suggested intestinal obstruction were underwent plain scan and second phase enhanced scan in whole abdomen. The image data was post-processed through GEADW4. 4 station with multi-planar reconstruction (MPR) and maximum intensity projection (MIP). The CT image characters of agnogenic intestinal obstruction were analyzed by comparing CT image suggestions with operation findings. Results MSCT clearly indicate the location, cause and severity of intestinal obstruction, and the diagnose accordance rate with operation findings was 95.6 % (65/68). Conclusions MSCT is a quick, simple and effective means for diagnosis of the location,causes and severity of agnogenic intestinal obstruction. It could provide an important clue for the doctors when making clinical decisions.

Objective: To investigate the inhibitory effects and mechanism of a novel anti-human DR5 ( death receptor 5 of TRAIL) monoclonal antibody to glioma cell lines U343. Methods: DR5 protein was tested quantitative through FCM: DR5 mRNA was observed through RT-PCR and distribution was tested by immunocytochemistry. Inhibitory effects and inducing apoptosis of anti-human DR5 monoclonal antibody to U343 were analysed by MTT, DNA Ladder, FCM. Results: The expression of death receptor 5 ( DR5 ) was certificated in U343 , DR5 appeared to be located in intracellular perinucle-ar compartment. Inhibitory effects of anti-human DR5 monoclonal antibody on U343 were achieved by 3 ?g/ml at 4 hours and the mechanism was associated with apoptosis. Conclusion: Apoptosis of glioma cell lines U343 can be induced by anti-human DR5 monoclonal antibody, and targeted on DR will provide new way to treating cancer.

Objective To explore the effects of cluster needling of scalp acupuncture combined with rehabilitation (Tang's Approach) onforelimb motor function and expression of synaptophysin and growth-associated protein (GAP-43) in rats after focal cerebral ischemia.Methods Endothelin-1(ET-1) was used to induce focal cerebral ischemia model in rats with forelimb dysfunction. The rats were randomlydivided into 5 groups: sham operation group, model group, rehabilitation group, acupuncture group, and acupuncture with rehabilitationgroup, each group was divided into 4 subgroups by 3 d, 7 d, 14 d, and 21 d. 24 hours after modeling, the cluster needle of scalp point withskilled forelimb reaching was trained in the acupuncture with rehabilitation group, skilled forelimb reaching was trained in the rehabilitationgroup, and the cluster needle of scalp point only were punctured and stimulated in the acupuncture group. But the model group had no intervention.The success rates of forelimb reaching were analyzed and immuno-histochemical technique was used to observe the expression ofsynaptophysin and GAP-43 in cortical ischaemic lesions of the rats in each group at different time points. Results At different time pointsafter the treatment, the successful rate of forelimb reaching in the acupuncture with rehabilitation group was higher than the model group, rehabilitationgroup, and acupuncture group (P<0.05). Conclusion The cluster needling of scalp acupuncture combined with rehabilitationcan promote recovery of forelimb motor function in rats after focal cerebral ischemia, which may associate with the expression of synaptophysinand GAP-43 in cortex surro`unding following focal cortical ischaemic lesions.

Objective To explore the effects of task-oriented training on forelimb motor function and expression of synaptophysin andgrowth associated protein (GAP)-43 in rats after focal cerebral ischemia. Methods Endothelin-1 (ET-1) was used to induce focal cerebralischemia model in rats with forelimb dysfunction. The rats were randomly divided into 4 groups: sham operation group, model group,task-oriented training group and treadmill running group, each group was divided into 4 subgroups by 3 d, 7 d, 14 d, and 21 d. 24 hours aftermodeling, the rats in task-oriented training group were trained with forelimb reaching and the rats in the treadmill running group weretrained by treadmill, and the model group had no intervention. Motor function of rats was evaluated by net screen test, and immunohistochemistrystaining was used to observed the expression of GAP-43 and synaptophysin in cortical ischemia lesions of the rats in each groupat different time points. Results The scores of behavioral tests were better in the task-oriented training group than in the model group (P<0.01) and the treadmill group (P<0.05) on the 14th and 21st days after modeling. The expression of GAP-43 was higher in the task-orientedtraining group than in the model group (P<0.05) and the sham group (P<0.01) on the 7th and 21st days after modeling. The expression ofsynaptophysin was higher in the task-oriented training group than in the model group (P<0.05) and the sham group (P<0.05) on the 14th andthe 21st days after modeling. Conclusion Task-oriented training can facilitate the recovery of forelimb motor function of rats after focal cerebralischemia, and it may be partially related to the up-regulation of expression of GAP-43 and synaptophysin in peri-infarction cortex.

Objective To investigate the usefulness of acoustic radiation force impulse (ARFI) elastography for noninvasive evaluation of liver fibrosis in rats.Methods A total of 70 male Wistar rats were included in the group for dimethylnitrosamine (DMN)-induced liver injury,and 10 saline-injected rats were used as normal control.Hepatic injury was induced by a single intraperitoneal injection of DMN at a dose of 50 mg/kg of body weight.Several rats in the group with DNM injected and the normal control group were randomly selected and sacrificed at each of the following post-injection time:day 5,7,10,14,21,24,and 28.And their livers were taken for pathology analysis.All the rats underwent ARFI elastography before sacrificed in order to acquire a shear wave velocity (Vs) to represent liver stiffness.Correlation between Vs and the histological finding was analysed.ResultsAmong 58 successfully modeled rats,9,13,14 and 12 rats were found to be with S1,S2,S3 and S4 of liver fibrosis pathologically,respectively.And 10 rats were found to be with severe inflammatory activity without any fibrosis.Values of Vs increased with the stage of liver fibrosis ( P ＜0.05).There was a significant correlation between Vs and stage of liver fibrosis ( r =0.947,P =0.000).The areas under ROC curve for the diagnosis of fibrosis S≥S1,S≥S2,S≥S3 and S=S4 were 0.983,0.995,0.999 and 0.964,respectively;for the cutoff values of Vs were 1.59 m/s,2.13 m/s,2.33 m/s and 2.51 m/s,respectively,the sensitivity was 95.8％,92.3％,100％ and 84.6％,and specificity was 100％,100％,96.9％ and 95.6％,respectively.The values of Vs in the group with severe inflammatory activity were significantly higher than those in the control group ( P =0.000).ConclusionsARFI has a relatively high value in the evaluation of liver fibrfosis in rats,while severe inflammatory activity may affect its accuracy.
