Glycogen synthase kinase-3β( GSK-3β) is a serine-threonine kinase,which was originally identified as a key regula-tor of glycogen metabolism. In nervous system, GSK-3β partici-pates in many central and peripheral nervous system physiological processes through transcription,cell proliferation and differentia-tion. The abnormal activity of GSK-3βinduces downstream signa-ling molecules and gene expression abnormalities,which are in-volved in some neuropsychiatric disorders such as schizophrenia, bipolar disorder,Alzheimer's disease,and pain. In recent years, lots of basic and clinic researches focus on GSK-3β,which might gradually become critical theraptic target of many diseases. The article mainly reviews the mechanisms involved in abnormal acti-vation of GSK-3β related neuropsychiatric disorders.

Objective To identify the effect of IGFBPrP1 on the secretion of extracellular matrix in hepatic stellate cells through the Smad3 signaling pathway. Methods (1)Two pairs of chemically synthesized siRNAs (siRNA1, siRNA2) targeting Smad3 were transfected into HSC-T6 cells,real-time PCR and Western blot were used to evaluate the silence efficiency, and the better siRNA was used. (2)HSC-T6 cells were divided into four groups: Negative control group, siRNA-Smad3 transfection group, siRNA-Smad3+IGFBPrP1 group and IGFBPrP1 group. The better siRNA was chosen to transfect into HSC-T6 cells. The protein expressions of Smad3, fibronectin and Collagen Ⅰ were evaluated by Western blot. Results (1)siRNA2-Smad3 inhibited Smad3 gene expression stronger than another siRNA. (2)After transfection of siRNA2-Smad3, the protein expression of Smad3 was significantly decreased compared to the negative control group(P<0.01). The protein expression of fibronectin and Collagen Ⅰ in IGFBPrP1 stimulating HSCs treated with siRNA2-Smad3 were significantly decreased compared to that in IGFBPrP1 stimulating HSC without siRNA2-Smad3 (P <0. 01 ).Conclusion IGFBPrP1 induces the secretion of extracellular matrix in hepatic stellate cells through the Smad3 signaling pathway.

Objective To investigate the common chromosome abnormalities in the patients with multiple myeloma and the relationships of cytogenetic abnormalities and clinical features. Methods The interphase fluorescence in situ hybridization (I-FISH) analysis method was designed to detect RB1-/13q14-and 14q32 rearrangements in 49 MM patients. The statistic value of its effect on clinical features were determined. Results FISH disclosed 14q32 translocations in 26 of the 40 (53.1%) patients. 25 out of the 49 (51.02 %) cases were found with deletion of chromosome 13q14 included del(RB1) in 9 (18.4 %) and del(13q14.3) in 18 (36.7 %). 13q14 deletion and 14q32 translocation were simultaneously observed in 18 (36.7 %) cases. Spearman correlation analysis were found associated of 14q32 rearrangement with the percentage of plasma cells in bone marrow (r=0.316, P=0.27). Conclusion The frequency of 13q14 deletion and 14q32 gene translocation in multiple myeloma are high. There is a significant correlation between the presence of 14q32 translocations and chromosome 13 abnormalities in MM patients. The percentage of 14q32 translocation in plasma cells was increased significantly. The 14q32 translocation is an independent prognostic factor.
