METHODS:Astrocytes were identified with anti-glial fibrillary acidic protein antibody. The TF activity of cell lysate was measured with one stage clotting assay. RESULTS:TF activity of astrocytes of LPS,IL-6,TNF? groups were obviously higher than that of the control group( P

An empirical study on the analysis of the social responsibility information which includes corporate social responsibility reports, annual reports and official website social responsibility part, of 62 selected Chinese listed corporate is performed using co-word analysis. We have clustered 39 key words which refined from the social responsibility management information into five index, which are characteristics of traditional Chinese medicine industry, cultural, quality, operation and sustainable development. The quality of construction, cultural products and characteristics of traditional Chinese medicine industry itself are the hot social responsibility information, and also can be used as key factors in the enterprise brand evaluation of traditional Chinese medicine.

Objective To analyze the relationship between needs of assistive devices and the three other factors (age, disability categories, severity levels of disability) in order to scientifically formulate subsidy policy on assistive devices.MethodsThe assessment of rehabilitation needs for 928 Shenzhen citizens with new disability certificates in its six districts was performed by professionals, and the data was recorded into ACCESS database and analyzed.ResultsThe sequence of demand rates on assistive devices among disability categories was vision disability (78%), hearing disability (76%) and physical disability (74%); but speech, mental retardation and psychological disabilities had a low demand. The demand rates of assistive devices were dissimilar among four age groups for persons with vision, hearing and physical disabilities; for severity levels of three disability categories of vision, hearing and physical disabilities: the milder the vision disability was, the greater demand rates of assistive devices were; the demand rate of those with the second level of hearing disability was the highest; the demand rates of persons with the first and second levels of physical disability were relatively higher.ConclusionWhen drawing up subsidy policy on assistive devices for persons with disability, the disability categories, ages of persons with disability and severity levels of disability should be considered; the different types of assistive devices should be supplied according to rehabilitation goals at different age group; and necessary assistive devices should be provided according to severity levels of disability.

Based on the current status of allocation, demands and utilization of medical care resources and the needs for future development in Shanghai, the overall objectives, principles, key plans of allocation of medical care resources in the 12th Five-years Plan in Shanghai and the leading role of health bureaus at all levels were discussed.

AIM: To evaluate the implication of CXCL10-loop3-EGF fusion protein for the activities of targeting tumor and anti-angiopoiesis. METHODS: RT-PCR was preformed to amplify CXCL10 coding sequence from PBMC activated by IFN-γ. CXCL10-loop3-EGF fusion gene, which was conducted by Over-Lap Extention PCR, was hinged up with plasmid pTG19-T, transfected to E. coli DH5α and processed positive colony selection. After ligated with plasmid pET32a(+), recombinant CXCL10-loop3-EGF fusion gene was then transfected to E. coli Origami B (DE3) and induced to express its coding fusion protein his-CXCL10-loop3-EGF. The recombinant fusion protein CXCL10-loop3 -EGF was purified by His-bind affinity chromatograph, enterokinase cleavage, ultrafiltration and dislysis. The transwell chemotatic test and HUVEC angiopoiesis inhibition test were performed to determine the anti-tumor responses and anti-angiopoiesis activity of CXCL10-loop3-EGF fusion protein. RESULTS: CXCL10-loop3-EGF fusion protein was successfully constructed and confirmed by SDS-PAGE analysis and Western blotting. Significant PBMC chematatic activity and HUVEC anti-angiopoiesis activity were observed. CONCLUSION: CXCL10-loop3-EGF fusion protein, which has perfect anti-tumor activity, is successfully constructed.

Objective To assess the irregular shape of hematoma with math methods,which is one of the risk factors of hematoma enlargement.Methods We reviewed images data of patients with spontaneous intracerebral hemorrhage treated nonsurgically who underwent initial computed tomography (CT) within 6 hours and repeated CT within 48 hours of onset.The area(s),the circumference(L),the greatest diameter(A)and the transverse diameter(B)of the greatest hemorrhage CT slice was measured.The formula X=L/S waft used to calculate the value.We calculated the area(S1)and the circumference (L1) of the ellipse with A as its long diameter and B as its short diameter.The formula X1=S1/L1 was used to calculate the value. We used formula R=X/X1 to assess the irregular hematoma shape.The relationships between hematoma enlargement and R was analyzed. Results Thirty-one patients(25.8%) showed enlarged hematomas after admission.The larger the value of R,the more irregular the shape of hematoma.When R≥1.3,the shape of the hematoma was significantly irregular.36.0% patients with R≥1.3 had hematoma enlarged.compared with only 18.6% those with R<1.3(χ2=4.62,P=0.032).Conclusions The irregular shape index R Can be used to assess the shape of a hematoma. A particularly high likelihood of hematoma enlargement is observed in patients with an irregularly shape index R≥1.3.

Objective To observe the effects of intermittent hypoxic preconditioning on the expression of apoptosis-related EPO after 70％ hepatectomy combined with ischemia-reperfusion injury.Methods One hundred and twenty healthy SD rats of clean grade,simple random divided into 3 groups:Sham operation group of 40 rats ; Pure major hepatic resection group was 40 (Major hepatectomy,MH),namely in the hepatic portal blocking liver resection of the left and middle lobes,hepatic portal blocking 20 min ; intermittent hypoxia preconditioning group 40 (Intermittent hypoxia preconditioning,IHP group).Results MH group,S group,IHP group,EPO level in three experimental groups in postoperative residual liver tissue in rats with significant difference (P ＜ 0.05),Intermittent hypoxia preconditioning group of residual liver EPO content was significantly higher than that of simple hepatic resection group 40.Conclusion Intermittent hypoxia preconditioning can promote the expression of residual liver after hepatectomy in EPO.

OBJECTIVE: The aim of this study was to determine the expression of GATA-3 and the level of Th1 and Th2 cytokines upon repeated exposure to staphylococcal enterotoxin B(SEB) of different concentrations in the maxillary sinus mucosa of rabbits. METHOD: The rabbits were randomly divided into 2 groups (24 rabbits per group): low-dose SEB group and high-dose SEB group. The low-dose SEB group and high-dose SEB group received daily injections of 0.6 ng of SEB (2 ml) and 60 ng of SEB (2 ml) into the left maxillary sinus of rabbits for 28 days, respectively. Concurrent treatment of the right maxillary sinus with normal saline was used as a control. Six rabbits chosen randomly in two groups were killed on days 3, 7, 14, and 28, and to obtain the sinus mucosa from the two-side maxillary sinuses for measurement. Mucosal levels of IL-2, IL-4, IL-5, and IFN-γ were measured using ABC-ELISA. Tissue expression of GATA-3 were examined using Real-time PCR and immunohistochemistry. RESULT: IFN-γ and IL-2 levels were significantly elevated in the high-dose SEB group compared with the low-dose SEB and control groups on days 7, 14, and 28 (P < 0.05). However, IL-4 and IL-5 levels were markedly enhanced in the low-dose SEB group compared with the high-dose SEB and control groups on days 14 and 28 (P < 0.05). Real-time PCR showed that the expression of GATA-3 mRNA in the low-dose SEB group was markedly enhanced, and immunohistochemical staining illustrated that the number of GATA-3 positive cells was markedly increased in the low-dose SEB group as compared with the high-dose SEB group (P < 0.05). No significant differences were observed in GATA-3 expression between the high-dose SEB and the control groups (P > 0.05). CONCLUSION SEB promoted Th1 cytokines production at high concentrations, and enhanced Th2 cytokines expression and Th2 immune response at low concentrations.
