Objective To observe the regulation of sry-related high-mobility-group box-containing 2 (Sox2) on epidermal growth factor receptor(EGFR)and on the sphere formation rate of glioma stem cells .Methods Promoter reporter plasmids of epidermal growth factor homologous receptor ErbB2 ,ErbB3 ,ErbB4 were respectively constructed .Sox2 expression plasmid was co-transfected together with the reporter plasmid into U251 cells .Then the luciferase activity was analyzed by dual-luciferase reporter assay sys-tem to test the regulation of Sox2 on ErbB2 ,ErbB3 ,ErbB4 promoters .Sphere formation assay was used to observe selfrenew of the cancer stem cells after transfection of Sox 2 .The expression of EGFR and ErbB2 proteins in the spheres was examined by Western blot .Results Sox2 could dose-dependently increase the ErbB2 ,ErbB3 ,ErbB4 promoter drived luciferase activity .Sox2 promotes the sphere-forming rate of U251 cells and upregulates the expression of EGFR and ErbB2 in the spheres .Conclusion Sox2 could up-regulate the expression of EGFR and promote selfrenew of glioma stem cells .

Objective: To observe the clinical efficacy and eligibility of thumb-tack needle therapy based on meridian differentiation in treating cervical radiculopathy. Methods: A total of 70 patients with cervical radiculopathy were randomized into an observation group and a control group, with 35 cases in each group. Patients in the control group received thumb-tack needle based on conventional point selection, while those in the observation group received thumb-tack needle according to meridian differentiation. The visual analog scale (VAS) and clinical symptom scores in the two groups were compared before and after treatment, and the clinical efficacy of the two treatments was observed. Results: After treatment, the VAS score in both groups dropped significantly (both P<0.01), and the VAS score in the observation group was lower than that in the control group (P<0.01). The clinical symptoms score in both groups dropped significantly (all P<0.01), and the clinical symptoms score in the observation group was lower than that in the control group (P<0.01). The total effective rate in the observation group was higher than that in the control group (P<0.05). Conclusion: Thumb-tack needle therapy based on meridian differentiation can reduce pain score, improve clinical symptoms in patients with cervical radiculopathy, and produce more significant efficacy compared with conventional thumb-tack needle therapy.

Objective To study the immune regulatory effect of natural killer cell(NKT) in the early stage of murine liver injury induced by type 5 adenovirus(Ad5). Methods Animal models were con-structed by injected C57BL/6 mice with 1.5×109-3×109 PFU Ad5 into the tail vein. Liver injury of mouse at day 0, 1, 2, 3, 4, 5 after infection was determined by HE staining and serum ALT/AST(alanine amin-otransferase/aspartate aminotransferase) level. Flow cytometry analysis was used to measure the proportion of lymphocytes, expression of Fas/FasL on the surface of NKT cells and level of IL-4, IFN-γ/in NKT cell plasma in the infected mouse liver. RT-PCR was applied to semi-quantify the chemokines and their receptors mRNA in infected mouse liver. Results NKT cells of mouse increased significantly at day 1 after infected with high titer Ads(3×109 PFU), expression of FasL on NKT cell and plasma IL-4, IFN-γ/level in NKT cells were also up-regulated, hence the obviously infiltration of lymphocytes in routine liver. Comparing with high titer Ads infection, low titer Ads infection (1.5×109 PFU) lead to little change of NKT cell proper-tion, and fewer infiltration of lymphocytes in murine liver. Hepatic chemokine RANTES, 1P-10, and MIP-1β mRNA expression in C57BL/6 was up-regulated 2 d after intravenous administration of 3×109 PFU Ad5. Corresponding chemokine receptor CCR5, CCR1, CXCR3 mRNA expression was up-regulated 3 d after in-fection. Conclusion NKT cells play an important role in lymphocytes recruitment into the liver of mouse in-fected with AdS, which may relate to up-regulatio of the plasma IL-4, IFN-γ level and expression of FasL of NKT cells, therefore facilitating the production of chemokines, e.g. IP-10 and Mig.

Objective To design simulated pulmonary air embolism demonstration model,so as to solve the problem of pathological anatomy of pulmonary air embolism in experiment teaching. Methods According to the principle of the disturbance of local blood circulation and air embolism, we designed a pulmonary air embolism model. We took 223 school nursing students as the object of this study,and randomly divided them into 2 groups:animal experiment teaching group and model control group,then we compared the teaching effect between the two groups. Result The test scores of students in the animal experiment teaching group were higher than control group (P<0.05) . Conclusion The use of simulated pulmonary air embolism demonstration model teaching can improve the students’experimental test scores,and can be repeatedly used,stimulate students' study interest,reduce the cost of teaching,and improve the teaching quality.

Objective To explore the therapeutic effects of peroxisome proliferator activating receptor γagonist-rosiglitazone on HMGB1 expression in liver tissue of rats with SAP. Method A hundred and twenty Wistar rats were randomly (random number) divided into the sham operation group(SO group, n = 20) ,SAP group ( n=80) and ROSI treatment group (n =20). SAP group were randomly further divided into the 3 h, 6h, 12 h and 24h subgroups with 20 rats in each group. SAP model was made by retrograde injection of 5 % sodium deoxycholate into the biliopancreatic duct. The serum amylase, AST and ALT, and pathological scores of pancreas and liver tissue were observed. The expression of NF-κB mRNA and the level of HMGB1 protein were investigated respectively by Reverse transcription polymerase chain reaction (RT-PCR) and Westem blot method, respectively. SPSS 16.0software was used to make one-way ANOVA, q -test and correlation analysis. Results Serum amylase, AST and ALT, and pathological scores of pancreas and liver tissue, and the level of HMGB1 protein were markedly increased in each subgroup of SAP compared with SO group ( P < 0.01). The level of HMGB1 protein was positively correlated with the changes of AST, ALT and pathological scores of pancreas and liver tissue. Correlation was not found between HMGB1 and amylase. Treatment with ROSI could significantly reduce the expression of NF-κB mR-NA and the levels of HMGB1 protein, serum AMY, AST and ALT, and pathological scores of pancreas and liver tissue in comparison with 24 h subgroup of SAP (P <0.01). Conclusions As a late-acting mediator of inflammation, HMGB1 was involved in the pathophysiological process of SAP-related liver injury. ROSI can reduce the liver injury by inhibition of the expression of the HMGB1.

OBJECTIVETo compare the difference in the efficacy on low back pain of cold-damp pattern between electric-thermal Bian-stone therapy and moxibustion box therapy.
METHODSForty-one cases of low back pain of cold-damp pattern were randomized into an electric-thermal Bian-stone therapy group (group A, 26 cases) and a box moxibustion therapy group (group B, 15 cases). In the group A, the electric-thermal Bian-stone was placed over Shenshu (BL 23) and Weizhong (BL 40). The temperature of stone was adjusted in accordance with patient's comfort. In the group B, moxibustion box was used over Shenshu (BL 23) and Weizhong (BL 40). The treatment was given once every day or every two days. Ten treatments made one session. The symptom and physical signs score of low back pain and the score of cold-damp syndrome were observed before and after treatment in the patients.
RESULTSThe symptom and physical signs score of low back pain and the score of cold-damp syndrome were all improved in the two groups (all P < 0.01). The changing rate of symptom and physical signs and syndrome were (37.04 +/- 32.68)% and (22.85 +/- 29.95)% in the group A, and were (47.29 +/- 22.08)% and (23.89 +/- 22.53)% in the group B, respectively, without significant difference in comparison between the two groups (all P > 0.05).
CONCLUSIONThe efficacy on low back pain of cold-damp pattern treated with the electric-thermal Bian-stone therapy is similar to that of moxibustion box therapy. This therapy is characterized as more convenient, safer operation and less pollution.
