1.Retinal Mosaics Related to Eye Development and Formation
Progress in Biochemistry and Biophysics 2001;28(2):137-139
Different types of neurons are regularly dispersed on re tina. For finding the mechanism of eye and retina formation, it is important to know how t his regular pattern is formed during embryonic stage. It was claimed that multip le genes regulate the development of eye and retina. These genes regulate the de velopment of tissues and differentiation of cells in different parts of the visu al system during embryo development. Also, it was found that different tissues a nd differentiated cells cohere with each other both temporally and spatially to form the eye.

To obtain fusion protein of Mycobacterium bovis with high purity, the recombinant prokaryotic expression vector for Mb2277 gene was constructed and the immunogenicity of its products was initially investigated in the present study.A pair of primer was designed according the gene sequence Mb2277 from the genomic DNA of M.Bovis in GenBank. and was amplified by PCR using DNA of M.Bovis 93006 strain as template. The PCR product and pET-28a(+) was then digested by BamHⅠ and EcoR Ⅰdouble enzyme. To constructed a prokaryotic expression plasmid, the purified Mb2277 was cloned to pET28a(+). Then the recombinant plasmid was transformed into competent cell of E.coli BL21(DE3).The bacteria were induced by IPTG and its lysates were analyzed by SDS-PAGE and Western-blotting. In this way, the prokaryotic expression plasmid for M. bovis Mb 2277 protin was obtained, and a expression band with molecular of 25 ku could be found in SDS-PAGE analysis. As demonstrated by Western blotting this expression product showed excellent reactivity with rabbit immune sera against M. bovis.

(2) AA, AG and GG genotype frequency of power-oriented athlete respectively was 0.442,0.302 and 0.256, frequency of GG genotype and G allele was higher than the control group, there were significant differences compared to thecontrol( P < 0.05, df = 2); (3) A/G genotype frequency of Endurance-oriented athletere spectively was 0.571, 0.400 and 0.029, there were nosignificant differences compared to the controls ( P > 0. 05, df = 2). (4) A/G genotype frequency of Uyghur soccer athletes respectively was0.472, 0.361 and 0.167, G allele was higher than the Endurance-oriented athlete and lower than the power-oriented athletes. and no significant differences compared to the controls( P > 0.05, df = 2).
CONCLUSIONThe results indicate that the CKMM gene GG genotype and G alleleare represented in power-oriented athletes, but don't find A/G polymorphism correlation with endurance and the football sport performance.

To clear the kinds of trace elements which is closely related with the active ingredient, proclaim the effects of trace elements on the quality of the Glycyrrhizae Radix et Rhizoma, provide the theoretical foundation to the further quality control of cultivation, take the advantage of the HPLC to determine the contents of glycyrrhizic acid and the liquiritin according to Chinese pharmacopoeia, use the inductively coupled plasma mass spectrometry to test the contents of Cu, Zn, Mn, Pb, Se, Cd, Ni, La, Na, Cr, M, Fe, Ca, Al, K, Sr, then, use SPSS statistical software for active ingredient and trace elements Correlation Analysis. The result of correlation analysis showed that Liquiritin contents of Glycyrrhizae Radix et Rhizoma have strong a positive correlation with the Mn, Pb contents, well, have a negative correlation with the Cu, Na contents; Glycyrrhizic acid contents showed a positive correlation with Mg, Cd, La contents, however, it showed a negative correlation with K, Fe contents. Comprehensive analysis of the results of the study, a preliminary thought that the active ingredient of Glycyrrhizae Radix et Rhizoma closely related with the trace elements, but the exact conclusion still need further study concentration-response relationship analysis.

OBJECTIVETo investigate the effect of histone deacetylase inhibitor suberic bishydroxamate (SBHA) on human acute myeloid leukemia (AML) cell lines.
METHODSAML U937, KG-1 and Kasumi-1 cells were treated with SBHA. Cell growth was measured by MTT assay. Apoptosis was determined using flow cytometry. Activation of Caspase pathway and expression of apoptosis regulator proteins were detected by Western blot.
RESULTSSBHA significantly induced growth arrest and apoptosis in U937, KG-1 and Kasumi-1 cells. Enhanced apoptosis was observed in SHBA group evidenced by strong activation of Caspase-9, Caspase-8 and Caspase-3. SHBA treatment resulted in down-regulation of anti-apoptotic protein Bcl-2 and Bcl-xl expression; down-regulated expression of antiapoptotic proteins survivin, XIAP and cIAP was also detected after SBHA treatment.
CONCLUSIONSBHA can effectively kill AML cells by inhibiting cell growth and inducing apoptosis, which is associated with the activation of Caspase pathway and regulation of apoptotic related proteins.

Objective:To analyze a Risk Scale for Emergence Agitation After General Anesthesia in Children (the EA risk scale) into simplified Chinese and evaluate the reliability and validity in children with strabismus correction surgery.Methods:After obtaining the authorization of the original author, the English version of the EA risk scale was translated, translated back and culturally debugged to form the Chinese version of the EA risk scale. Then 279 children with strabismus correction surgery were selected from a tertiary hospital of ophthalmology in Tianjin and were investigated to validate the scale.Results:The correlation coefficients of each item and the total score of the scale were respectively 0.768 (item 1) ,0.717(item 2), 0.676(item 3), 0.634(item 4) (all P < 0.01). Content validity index of the scale was 0.920, and each item was 0.80-1.00. One factors including 4 items were identified using exploratory factor analysis, accounting for 62.052% of the total variance. The optimal cut-off value for the EA risk in children was 10, with the AUG was 0.816, specificity of 0.704, and sensitivity of 0.839. The Cronbach α coefficient for the total scale was 0.819, and the intraclass correlation coefficient value between the scorers was 0.835. Conclusion:The Chinese version of the EA risk scale has good reliability and validity. The items are concise, clear, and easy to understand. It is suitable for clinical departments as a preliminary screening tool to identify emergence agitation after general anesthesia on children with strabismus correction surgery and to assess the risk of its occurrence.

There were significant increase in urine protein excretion,raised malondialdehyde(MDA) level and expressions of NF-?B,p22phox and p47phox in renal tissue,and significant decrease in reduced glutathione,superoxide dismutase,vitamin C and E levels in type 2 diabetic Goto-Kakisaki rats after 12 weeks. There was obvious histomorphologic change in the kidneys.All the above indices were improved by intraperitoneal injection of?-lipoic acid(35 mg/kg q.o.d).Besides,significant positive correlations were found of MDA level to p22phox,p47phox and NF-?B in the renal tissue,?-lipoic acid seems to protect the diabetic kidney in this diabetic rat model via antioxidative effects.
