BACKGROUND: It has been found in recent years that STAT3 widely distributes in nervous system, including hippocampal CA1-3 region, dentate gyrus and cerebral neocortex, etc. Ischemic brain injury can cause the release of some cytokines and growth factors, while electro-acupuncture may have multi-level, multi-channel and multi-target protective and interventional effects on ischemic brain injury. OBJECTIVE: To observe the effects of electro-acupuncture on STAT3 expression and nuclear translocation in hippocampal CA1 region of rat models of brain ischemia/reperfusion. DESIGN: Randomized and controlled observation. SETTING: Staff Room of Acupuncture and Moxibustion, Department of Acupuncture and Bone Injury, hubei college of Traditional Chinese Medicine; tongji medical college, huazhong university of science and technology. MATERIALS: Seventy-two healthy SD rats, of clean degree and either gender, weighing (200±20) g, were provided by the Experimental Animal Center of hubei college of Traditional Chinese Medicine. STAT3 monoclonal antibody was purchased from Santa Cruz Company, USA, and G-6805 electro-acupuncture instrument was purchased from Shanghai medical Electronic Instruments Factory. METHODS: This experiment was carried out in the comprehensive laboratory of Department of Acupuncture and Bone Injury, hubei college of Traditional Chinese Medicine between September 2005 and February 2006. Seventy-two rats were randomly divided into 4 groups: ① control group(n =6): Untouched. ② Sham-operation group (n =18): Artery was isolated, but without inserting thread bolt.③ Model group (n =24): Rat models of local brain ischemia/reperfusion were established with modified suture occlusion. ④Electro-acupuncture group (n =24): Dazhui and bilateral Neiguan points were selected for electro-acupuncture treatment. No. 28 acupuncture needle of 3.33 cm was used in the treatment. A G-6085 electro-acupuncture instrument with continuous wave, frequency of 120 times/min, intensity of 1 mA

Aim: To investigate the anticancer effects and the molecular mechanisms of deguelin on human U937 leukemia cells, and to explore the underlying mechanism regulating nucleoporin 98 （Nup98） and nucleoporin 88 （Nup88） in vitro. Methods: The effects of deguelin on the growth of U937 cells were studied by MTT assay. The effect of deguelin on the cell cycle of U937 cells was studied by using a propidium iodide method. The localization of the nuclear pore complex proteins Nup98 and Nup88 was investigated by using immunofluorescence and immunoelectron microscopy. The expression of Nup98 and Nup88 in U937 cells was investigated by using flow cytometry and Western blot. Results: The prolif eration of U937 cells was inhibited in the deguelin-treated group, with a 24-h IC50value of 21.61 nmol/L and a 36-h IC50value of 17.07 nmol/L. U937 cells treated with deguelin had reduced percentages of cells in the G0/G1phase, whereas cells accumulated in the S and G2/M phases. Nup88 and Nup98 were found on both the nuclar and cytoplasmic sides of the U937 cells by using immunofluorescence and immunoelectron microscopy. The expression of Nup98 was upregulated and that of the Nup88 protein was downregulated in U937 cells treated with deguelin. Conclusion: Deguelin is able to inhibit the proliferation of U937 cells by regulating the cell cycle such that cells are arrested at the S and G2/M phases, so that the proportion of cells in the G0/G1phase decreases. The antitumor effects of deguelin are related to upregulating the expression of Nup98 and downregulating the expression of Nup88 protein in U937 cells.

Objective To investigate prevalence rate of learning disabilities (LD) in Chinese children, and to explore related risk factors, and to provide theoretical basis for preventing such disabilities. Methods One thousand and one hundred fifty one children were randomly selected in primary schools. According to criteria set by ICD-10, 118 children diagnosed as LD were classified into the study group. Four hundred and ninety one children were classified into the normal control group. Five hundred and forty two children were classified into the excellent control group. The study instruments included PRS (The pupil rating scale revised screening for learning disabilities), Conners' children behavior check-list taken by parents and YG-WR character check-list. Results The prevalence rate of LD in Chinese children was 10.3%. Significant differences were observed between LD and normally learning children, and between the LD group and the excellent group, in terms of scores of Conners' behavior check-list (P china. LD is resulted from a number of factors. Good studying and living environments should be created for LD children.

In order to assess the significance of BCR/ABC fusion gene in adult acute lymphoblastic Leukemia (ALL), 28 patients who were diagnosed as ALL were enrolled to detect BCR/ABC gene using nested-RT-PCR. The results showed that 9 cases (31.25%) were BCR/ABL positive, and expressed P210 subtype. Among them 7 cases were B-ALL, and one was T-ALL. The diagnosis was proved by monoclonal antibodies recognition by indirect immunofluorescence. Adult patients with BCR/ABL positive ALL were significantly older (p0.05). The induction failure rate was high in BCR/ABL positive patients and those who achieved complete remission usually relapsed earlier. In conclusion, adult ALL patients with BCR/ABL-positive have poorer prognosis.
