BACKGROUND:Bone marrow mesenchymal stem cel s are likely to repair renal injury by differentiating into renal parenchymal cel s. OBJECTIVE:To explore the effect and mechanism of bone marrow mesenchymal stem cel s in the renal repair after mesangial proliferative glomerulonephritis. METHODS:Thirty Sprague-Dawley rats were randomized into normal group, model group and treatment group (n=10 per group). Model group and treatment group were treated with tail vein injection of mouse anti-rat monoclonal antibody Thy1.1 to prepare mesangial proliferative glomerulonephritis models. One week after modeling, rats in the treatment group were given 2×106 bone marrow mesenchymal stem cel s via the tail vein, and rats in the other two groups were given the same volume of normal saline. Two weeks after transplantation, urinary protein, urea nitrogen, creatinine levels were detected;hematoxylin-eosin staining was used for observing pathological changes of the renal tissue under microscope;and the expression of transforming growth factor beta 1 was detected by immunohistochemistry method. RESULTS AND CONCLUSION:The levels of urinary protein, urea nitrogen and creatinine as wel as the expression of transforming growth factor beta 1 in the renal tissue arranged in descending order were listed as fol ows:model group>treatment group>control group, and there were significant differences among three groups (P<0.05). In the model group, diffuse glomerular hyperplasia was observed with the presence of increased extracel ular matrix, partial glomerular sclerosis, and interstitial infiltration of inflammatory cel s;in the treatment group, glomerular hyperplasia, mesangial proliferation and inflammatory cel infiltration were al mitigated compared with the model group. Therefore, bone marrow mesenchymal stem cel transplantation may contribute to renal repair after mesangial proliferative glomerulonephritis, by inhibiting overexpression of transforming growth factor beta 1 in the kidney.

A capillary electrophoretic method was developed for the separation of enantiomers of naphthylgly-cidic ether(NGE). Several cyclodextrins(CDs) were applied as the chiral selectors and it was found that the ionic modified highly sulfated cyclodextrin(HS-β-CD) could give satisfactory enantioselectivity. In addition,the effects of the pH value of the buffer system,the concentration of the HS-β-CD,capillary temperature and the running voltage on the chiral separation were investigated systematically. The result showed that under the optimized conditions of pH 2. 5,20 mmol/L H_3PO_4-triethanolamine buffer containing 2% highly sulfated cyclodextrin ( HS-β-CD) at capillary temperature 20℃ in the reversed polarity voltage of - 18 kV,the enantiomers of naphthylglycidic ether were baseline separated. This method is simple,precise and can be applied to the chiral separation of naphthylglycidic ether enantiomers and determination of enantiomers excess(ee,% ).

This paper is to report the investigation on the metabolic behavior of Staphylococcus aureus (S. aureus) after given Qingkailing injection, and with the aim of seeking for a new quality control method based on biological assessment. The growth thermogenic curves of S. aureus were determined by microcalorimetry and analyzed by computer. The results showed that in the concentration range of (0-5.00%), the growth thermogenic curves of S. aureus were declined and removed back with increasing dosage of Qingkailing injection; the main parameters (T1, T2, k1, P1, P2 and I) and the dosage of Qingkailing injection have good correlation. The 50% inhibiting dosage is 3.26 %, and the optimal inhibiting dosage is 5.47%. Difference could be detected among the Qingkailing injection samples from different factories and different batches. It is proved that Qingkailing injection could inhibit the metabolic behavior of S. aureus, and microcalorimetry might be applied in the quality assessment of Qingkailing injection.

Objective To investigate the biological function of M122 in pathogenesis of MCMV in developmental brain disorders and brain damage, screening for mouse brain cDNA library interacting with M122 was performed by a yeast two-hybrid system. Methods The reconstructed bait plasmid pGBKT7-M122 was transformed into yeast cells AH109 and screened on the nutrient deficiency medium SD/-Trp. After express of the bait protein in AH109 yeast strains was detected by Western blot analysis, yeast-two hybrid screening was performed by mating AH109 with Y187 containing mouse brain cDNA library plasmid. The diploid yeast cells were plated on the nutrient deficiency medium SD/-Trp/-Leu/-His/-Ade. The second screening was performed with SD/-Trp/-Leu/-His/-Ade containing X-α-gal. The plasmids in positive colonies were extracted and transformed into E. coli JM109 cells. After plasmid DNA in JM109 cells were extracted form positive colonies and sequenced, the results were analyzed by bioinformatic methods. The interactions between M122 protein and the protein obtained from positive colonies were further confirmed by repeating yeast-two hybrid. Then, autoactivations of the proteins obtained from positive colonies were detected.Results The reconstructed bait plasmid was transformed into yeast cells AH109 successfully. The bait protein expressed in the yeast cells AH109 stably. 24 proteins interacting with MCMV M122 were screened, including syntaxin 8 ( Stx8 ), phosphoglucomutase 2 ( Pgm2 ), potassium voltage-gated channel, shaker-related subfamily, beta member 1 ( Kcnab1 ), collagen, type ⅪⅩ, alpha 1 ( Col19a1 ), archain 1 ( Arcn1 ), cytidylate kinase( Cmpk), DnaJ(Hsp40) homolog, subfamily A, member 1 (Dnaja1), ATPase, Na+/K + transporting, beta 3 polypeptide( Atp1b3 ), SH3-domain GRB2-like ( endophilin ) interacting protein 1 ( Sgip1 ),ankyrin repeat domain 17 (Ankrd17), Smg-7 homolog, nonsense mediated mRNA decay factor(Smg7),sperm associated antigen 9 ( Spag9 ), FK506 binding protein 1a ( Fkbp1a), MYST histone acetyltransferase monocytic leukemia 4 ( Myst4), hyaluronan and proteoglycan link protein 1 ( Hapln1), autophagy-related 3 (Atg3), splicing factor, arginine/serine-rich 5 ( Sfrs5 ), zinc finger, C3HC-type containing 1 ( Zc3hc1 ),thioredoxin-related transmembrane protein 1 ( Txndc1 ), adaptor protein complex AP-1, gamma 1 subunit (Ap1g1), Cullin 1 ( Cul1 ), and so on. Three of them were formerly unknown proteins. M122 protein could interact with the proteins obtained from positive colonies in the yeast cells AH109. Ap1g1 and Cul1 were proved to have autoactivation. Conclusion A class of proteins in brain interacting with M122 has been obtained. It is presumed that these proteins are correlated with neuropathogenesis of the brain disorders caused by CMV, but the candidates still need further confirmation for the interaction.
