AIM: To observe the effect of cannabinoid receptor (CB1R) agonist WIN55-212-2 on the expression of brain-derived neurotrophic factor (BDNF), c-Fos and protein kinase A beta-catalytic subunit (PKAC-β) in cerebrum cortex after intracerebral hemorrhage (ICH) in rats. METHODS: The intracerebral hemorrhage model of rat was made by the injection of collagenase Ⅶ, and WIN55-212-2 was intraperitoneally (ip) injected 30 min later. The rats were killed for sampling the brain tissues as specimens 24 h after ICH. The methods of immunohistochemical analysis and Western blotting were adopted to detect the expression of PKAC-β and BDNF. The mRNA expression of PKAC-β, c-Fos and BDNF was determined by RT-PCR. RESULTS: WIN55-212-2 obviously improved some nervous deficit symptoms and increased the expression of BDNF at mRNA and protein levels with upregulating the mRNA expression of c-Fos and downregulating the expression of PKA at mRNA and protein levels in the ipsilateral cerebral cortex. The proteins of PKAC-β, c-Fos and BDNF were expressed on the membrane or nucleus of the neuron or in the cytoplasm of glial cells, respectively. CONCLUSION: The expression of BDNF is induced not only by upregulation of c-Fos, but also by downregulation of PKA in WIN55-212-2 treated rats.

Interim fluorine 1 8 fluorodeoxyglucose (1 8 F-FDG)positron emission tomography (PET) integrated with computed tomography (CT) provides both metabolic and morphologic information,which becomes one of the most sensitive tools to evaluate the efficacy of the therapy and predict the prognosis of patients with lymphoma.Meanwhile,it is the basis for guiding trial design and changing clinical practice.How-ever,it is still a controversial issue in the ideal utilization of interim 1 8 F-FDG PET-CT imaging for the patients with lymphoma.

Objective To label human VEGF targeted bevacizumab (avastin) with 111In and to evaluate the application of 111 In?DTPA?avastin SPECT imaging for tumor diagnosis. Methods DTPA?avastin was prepared by coupling with a bifunctional chelating agent, and then labeled with 111 In to obtain 111 In?DTPA?avastin. The stability and molecular integrity of the labeled radiotracer were studied. Human hepatoma cell ( BEL7404) bearing nude mice tumor model was employed for tumor targeting evaluation. Gamma imaging was acquired after intravenous injection of 18.5 MBq probe. At the end of the observation, animals were sac?rificed for bio?distribution study. Results 111 In?DTPA?avastin tracer was synthesized and purified to a?chieve a radiochemical purity yield above 98% and specific activity up to 185 GBq/nmol. Its stability in 5%BSA was optimal, and the radiochemical purity after incubation for 96 h was over 90%. Gamma imaging re?sults showed that the tracer possessed definite tumor targeting property. Its biodistribution was consistent with that of normal in vivo antibody metabolism while possessing a good tumor?targeting property with a relatively high uptake of (3.8±0.8) %ID/g in tumor tissues 96 h after injection. Conclusions 111 In?DTPA?avastin tracer has good physicochemical properties, in vivo stability and good VEGF targeted binding. 111 In?DTPA?avastin has potential to be a new molecular probe for SPECT imaging.

Objective To investigate the clinical effectiveness and safety of Chinese medicine fumigation-washing therapy in treating talipes equinus denervated ulcer induced by tethered cord syndrome(TCS) . Methods A total of 21 qualified patients were randomized into fumigation-washing group (N=12) and antibiotics group (N=9). Patients of fumigation-washing group were given fumigation-washing therapy with the self-prescribed Chinese medicine, and antibiotics group was given intravenous dripping of sensitive antibiotics. The treatment lasted for 7 continuous days. The clinical efficiency of the two groups was evaluated after treatment, and the period of preparing for surgery was recorded. The changes of ulcer area and ulcer surface exudate volume in the two groups were observed before and after treatment. And the changes in blood routine examination, hepatic and renal function, and immune function of the fumigation-washing group were monitored. Results(1) The total effective rate of fumigation-washing group was 83.3%, and that of the antibiotics group was 77.8%, the difference being insignificant (P>0.05). (2) The ulcer area and ulcer surface exudate volume in both groups were significantly decreased after treatment (P<0.05 compared with those before treatment), and the decrease in the fumigation-washing group was superior to that of the antibiotics group(P < 0.05).(3) The period of preparing for surgery in the fumigation-washing group was(7.75 ± 1.71)d, shorter than(11.56 ± 4.39) d in the antibiotics group, the difference being significant(P < 0.05).(4) There were no statistically significant differences in the hepatic and renal function, and immunoglobulin and complement levels in the fumigation-washing group before and after treatment (P > 0.05). (5) The average daily hospitalization fee in the fumigation-washing group was (47.98 ± 5.17) yuan, less than (227.88 ± 43.24) yuan in the antibiotics group, and the difference was significant between the two groups (P < 0.05). Conclusion Chinese medicine fumigation-washing therapy is effective, safe and practical in treating talipes equinus denervated ulcer induced by TCS, and the therapy has the advantages of decreasing exudation, promoting ulcer healing, reducing hospitalization fee, shortening the period of preparing for surgery, and decreasing the incidence of infection.
