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.

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.

A commonly used Chinese crude drug Allii Macrostemonis Bulbus has been shown to possess good anticancer activities and related properties such as antioxidation, nitrite scavenging, nitrosamine synthesis blocking and immune enhancement, and has been widely used as an effective auxiliary drug in the treatment of some malignant tumors. This paper systematically reviews the advances in the study of anticancer-related activities of Allii Macrostemonis Bulbus's various components such as raw juice, extracts, saponins, volatile oil, polysaccharides, nitrogen compounds, etc.

OBJECTIVETo study the correlation between arachidonic acid (AA) and acute red blood cells damage in rats, and to build a model with hidden blood loss in vivo, and to explore the pathological mechenism of hidden blood loss.

METHODSA total of 50 male adult Sprague-Dawley rats weighing (200 ± 20) g were randomly divided into five groups (n = 10): control group and four experimental groups. The rats in the experimental groups were given 0.5 ml different concentrations of AA dilu- ents, 5, 10, 20, 40 mmol/L respectively. The blood samples were collected from orbital venous at the beginning and 24, 48, 72 hours after administration. Then the changes of hemoglobin (Hb) ,red blood cell count (RBC), glutathione peroxidase (GSH- PX) activity, total superoxide dismutase (T-SOD) activity and hydrogen peroxide (H202) in the blood samples were tested.

RESULTSSignificant hidden blood loss occurred when the concentration was 10 mmol/L in the experimental group, with the RBC and Hb sharply reduced in blood samples. The Hb and RBC were reduced in all the experimental groups and control group at 24 hours after administration, while in the experimental groups they changed more obviously. The GSH-PX activity, T-SOD activity and H₂O₂were also significantly reduced in all groups, and the changes showed significant differences. The Hb and RBC were relatively stable in the control group and the experimental groups at 48 hours after administration; while GSH-PX activity, T-SOD activity and H₂O₂were all significantly decreased, and the changes in the experimental groups were more notable.

CONCLUSIONElevated levels of AA in the blood causes oxidative stress in the red blood cells, leading to the damage of red blood cells and hemoglobin, which is responsible for hidden blood loss.

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.
