1.Progress of study on the KAI1 gene in gynecological tumor
Cancer Research and Clinic 2010;22(z1):64-66
KAI1 is a recently identified metastasis suppressor gene located at human chromosome 11 p11.2. KAI1 protein is a member of the structurally distinct family of cell surface glycoprotein and belongs to transmembrane 4 protein superfamily. KAI1 expression is down-regulated in many metastatic tumor cells. Down-regulation of KAI1 expression also plays an important role in the genesis and development of gynecological tumor.
2.A Structural Equation Modeling of Perceived Academic Self-efficacy, Learning Stress, and Learning Burnout of High School Students
Chinese Journal of Clinical Psychology 2006;0(05):-
Objective: To build a relationship model of perceived academic self-efficacy, learning stress, and learning burnout of high school students. Methods: 674 high school students were surveyed with Learning Stress Scale of High School Students, The Perceived Academic Self -efficacy Scale, Scale of Learning Burnout of High School Students. Results: Learning stress had a direct effect on a low level of learning efficacy, perceived alienation to teacher and physical exhaustion (The direct effect value were -0.22,0.12,0.27). At the same time, perceived basic ability and perceived control partially mediated the impact of learning stress on the low level of learning efficacy, perceived alienation to teacher and physical exhaustion (the mediated effect value were -0.155 and-0.264, 0.066 and 0.299, 0.089 and 0.233). Perceived basic ability and perceived control fully mediated the relationship between learning stress and emotional exhaustion (the mediated effect value were 0.033 and 0.387). Conclusion: The students with a higher level of stress reported suffering more learning burnout than those with a lower level of stress, and vice versa.

Cancer Research and Clinic 2013;25(10):693-695,699
Objective To evaluate the infection of high-risk human papillomavirus (HPV) and the expression of tumor metastasis suppressor protein KAI1 in cervical cancer.Methods The expression of KAH,HPV16/18E6 and HPV16E7 proteins were analyzed by immunohistochemistry SP assay in 117 cases of paraffin-embedded cervical tissue,including 20 normal cerival tissue as control,58 intraepithelial neoplasia (CIN) and 39 cervical cancer.Results In normal cervical tissue,CIN and cervical cancer,the positive rate of KAI1 protein were respectively 90.0 % (18/20),72.4 % (42/58),25.6 % (10/39).There was significant differience among three gruop (P < 0.01).The positive rate of HPV16/18E6 and HPV16E7 proteins were respectively 0 (0/20),31.0 % (18/58),41.0 % (16/39); 0 (0/20),34.5 % (20/58),64.1% (25/39).There were significant differience among three gruops (P < 0.01).There was no correlation between the expression of KAI1 and the infection of HPV (P =0.429).Expression of KAI1 was correlated to grade of differentiation,clinical stage and lymph node metastasis (P < 0.05),but was not correlated to age (P > 0.05).HPV infection was not correlated to the age,clinical stage,cell differentiation and lymph node metastasis (P > 0.05).Conclusion The expression of KAI1 protein is down-regulated in cervical cancer,which is not associated with the infection of HPV.

BACKGROUND:Studies have shown that astrocytes participate not only in the passive metabolic and structural support, but also actively in the central nervous system information processing. OBJECTIVE:By observing the directionality and specificity of astrocyte fiber growth and synapse formation, to explore the possible mechanisms of astrocytes and neurons in the interaction. METHODS: Primary cels from the hippocampi of green fluorescent protein transgenic newborn mice were isolated and cultured, glial fibrilary acidic protein was used as specific marker for astrocytes in immunofluorescence staining, and then the results were observed and scanned by confocal microscope. RESULTS AND CONCLUSION:The elongation of astrocyte fibers was directional and specific, and terminated to the pyramidal cels nearby. The end of astrocyte fibers and pyramidal cels contributed to the synapse formation. However, not al the projections were toward the adjacent cels, and synapse-like structure was not only formed nearby. The results implicated that both astrocytes fiber elongation and synapse formation have the directionality and specificity, providing evidence for further studies on signal transduction between astrocytes and pyramidal cels.

Objective To study a wavelet method for acquiring the characters of pulse wave based on the principle of wavelet transform which can effectively solve the problem of inaccuracy of the conventional methods. Method The method of wavelet module maximum was used to divide the pulse wave according to periods and basically decomposed it, by arranging in time order and symbolizing the module maximum character points of pulse wave signal at the ascending and descending edges as well as the crest and trough. Result Through the method, the unobvious dicrotism, trail wave and the anomalistic wave appearing at the ascending and descending edge of the main wave, and multi-scale characters and all kinds of characters in time domain of pulse signal were further acquired more accurately. Conclusion Simplicity, quickness and accuracy are achieved by focusing on the character points of pulse signals. It provides a new means for further studies of classification and identification of pulse signals.

BACKGROUND: To prepare a novel biological material that can be implanted into the lesion of bone tuberculosis, keep sustained release of anti-tuberculosis drugs around bone tuberculosis tissues for a long time, and enhance the effect on bone repair has become a hot spot for clinical studies on bone tuberculosis.OBJECTIVE: To prepare the adipose-derived mesenchymal stem cells (ADMSCs)/sustained-release rifampin-loaded microsphere complex, and to preliminarily study its effects in a rabbit model of spinal tuberculosis.METHODS: Rifampin-chitosan-calcium alginate sustained-release microspheres were synthesized, and co-cultured with ADMSCs to prepare an anti-tuberculosis composite for bone tissue engineering. Forty New Zealand rabbits were used to make lumbar L6 tuberculosis models. Thereafter, rat models were randomly divided into four groups and given rifampin by gavage in rifampin group, ADMSCs by paravertebral injection+rifampin by gavage in stem cell group, rifampin by gavage+implantation of the anti-tuberculosis composite material in experimental group, and no treatment in control group.The duration time of rifampin administration was 8 weeks. The anti-tuberculosis effect of the composite material was evaluated by X-ray and CT scanning observation.RESULTS AND CONCLUSION: In the control group, obvious damage to lumbar vertebrae L5 and L6 was apparent; inflammatory granulation tissues formed; and the intervertebral space was narrowed. In addition, two rabbits in the control group showed obvious kyphotic deformity and five showed pasoas major swelling with low-density dark region in the psoas muscle. In the rifampin group, there were five rabbits with moderate damage of the lumbar vertebrae L5 and L6,and two rabbits with pasoas major swelling. In the stem cell group, there were two rabbits with moderate damage of the lumbar vertebrae L5 and L6, three rabbits with mild damage of the upper part of the lumbar vertebra L6, and three rabbits with pasoas major swelling. In the experimental group, only four rabbits suffered from mild damage of the upper part of the lumbar vertebra L6 but with no changes in the intervertebral space between the L5 and L6, and without pasoas major swelling. These results indicate that the composite material of ADMSCs combined with sustained-release rifampin-loaded microspheres can inhibit mycobacterial growth effectively, and reduce vertebral bone destruction,thereby giving some therapeutic actions for the animal models with spinal tuberculosis.
