International Journal of Cerebrovascular Diseases 2011;19(11):853-856
p38 mitogen-activated protein kinase (MAPK) is an important intracellular signaling transduction pathway.Its major role is involved in inflammatory regulation and apoptosis.p38 MAPK is activated during the cerebral ischemia.Its expression level and the upstream and downstream protein phosphorylation levels will change.Ischemic preconditioning may mediate the survival or death of neuronal cells after cerebral ischemia through signaling transduction pathway.
5.The roles and mechanisms of hypoxia-inducible factor-1α in cerebral ischemia
International Journal of Cerebrovascular Diseases 2012;20(4):310-314
Hypoxia-induciole factor-1 (HIF-1) is an important transcription factor.It participates in the body's response to the hypoxic environment mainly through its active subunit HIF-1α.During cerebral ischemia and hypoxia,the expression of HIF-1α is upregulated and may activate the expressions of multiple downstream target genes involving glycolysis,vascular growth,cell survival and apoptosis.It has an important significance for the improvement of energy metabolism and the establishment of microcirculation after cerebral ischemia.HIF-1α can not only promote the neuronal survival,but also mediate delayed neuronal death.A variety of preconditioning and postconditioning methods may regulate the survival and death of neuronal cells by activating HIF-1α.

Objective:To test Jiang Guangrong's(2005)three-dimension model on the depth of counseling process.Methods:In this process-outcome research,28 sessions in a university counseling center were videotaped and coded in terms of the model.Structure Equation Model(SEM)was used to examine the relations between the coding and counselors and clients' evaluation of the session depth.Results:(1)Clients and counselors evaluated differently on the session depth,and clients' evaluation was more positive than counselors' [(4.95±1.12)vs.(4.23±0.94),P<0.05];(2)The model was significantly correlated with counselors' session depth evaluation(path coefficient = 0.55,P<0.01),but not with the clients';(3)The session curves describing each dimension changing over time had different patterns in sessions of different depth level,through which more about the counseling process could be known.Conclusion:The three-dimension model on the depth of counseling process has got some empirical evidences.
7.Establishing a rabbit model of peripheral partial growth plate closure by immediate filling after partial growth plate resection
Chinese Journal of Tissue Engineering Research 2008;12(15):2993-2996
BACKGROUND: Animal models of peripheral partial epiphyseal plate closure are commonly used in related trials.OBJECTIVE: To modify the original animal models of distal femoral partial epiphyseal plate closure.DESIGN, TIME AND SETTING: A self-controlled trial was performed at the Experimental Animal Center of General Hospital of Chinese PLA from March to October 2007.MATERIALS: Twenty healthy New Zealand rabbits of 4-6 weeks old weighing 1.0-1.5 kg were selected.METHODS: A straight incision about 2 cm was made in lateral knee of 20 rabbits. The subcutaneous tissues and knee capsule were cut open to expose distal femoral condyle. The condylar plate line was clear. Two holes were drilled in the fight lateral condyle, about 3.0-4.0 mm deep, and partial normal epiphyseal plate (about 33%-44% of the total growth plate) was removed. An incision deep to periosteum was created in the left side and regarded as self-control.MAIN OUTCOME MEASURES: Femoral length, valgus angle of the distal femur, and femoral deformity were detected by X-ray photograph, and gross observation. Bone bridge formation of bilateral femora was observed by histological examination.RESULTS: One rabbit died of diarrhea 31 days after surgery, and 19 were included in final analysis. ①Radiographs showed that the mean length of left femur (control side) was significantly longer but valgus angle was significantly smaller than the right side (experimental side) 4 months after surgery (P < 0.01). The left distal femur averagely grew for 2.27 cm,accounted for 57.6% of the overall femoral growth, and the right side averagely grew for 0.45 cm, accounted for 21.4% of the overall femoral growth.②Four months after surgery, femoral appearance of the control side was normal, with smooth and complete condylar and facies articularis patellae. While, the experimental side femur was significantly shortened, and severe vaigus deformity was observed in the distal femur. ③Five weeks after surgery, layer cells of the epiphyseal plate arranged regularly in the control side. Bone trabecula with many fibers was found in bone defect cavity of the experimental side, and the cell layer of the remnant epiphyseal plate was decreased. The epiphyseal plate was closed in the control side,and bone trabecula of the experimental side was thickened 10 weeks postoperatively.CONCLUSION: This modeling method is simple, efficient, and easy to manipulate; in addition, the bone bridge area is controllable. The models can meet the study demands for peripheral partial epiphyseal plate closure, and are significant for filling material selection during treatment.
