Objective To observe the effects of Yishen-Pinggan dcoction on the urine microalbumin and the expression of ACE2, AngⅡin the spontaneously hypertensive rat kidney(SHR);to observe the kidney level hepatic side of the protective effect of early renal in SHR hypertension. Methods The same old male SHR and normal rats(Wistar-Kyoto rats, WKY) for the study, at 10 weeks of age, SHR rats were randomly divided into a model group, a Chinese medicine group, and a lotensin group;while WKY rats were served as a normal control group(n=8). They were continuously treated for 12 weeks. Urine mAlb and β2-MG of rats were quantified at pre-experiment and after experiment, immuno-histochemical detection of renal ACE2 and AngⅡwere performed, the obtained results were statistically analyzed by computer image analysis. Result At the 12th week, compared with urinary mAlb(509.3±160.3)ng/ml,β2-MG(0.150±0.037)μg/ml, Ang kidneyⅡ(7 174.24±1 068.99)μm2,kidney ACE2(2 158.90±376.60)μm2 in the WKY group, the urinary mAlb(908.3 ±13.2)ng/ml, β2-MG(0.378±0.099)μg/ml, kidney AngⅡ(11 085.37±1 398.03)μm2 in the hypertension model group were significantly higher(P<0.01), and kidney ACE2(1 375.77±466.21)μm2 was decreased significantly(P<0.01); compared with hypertensive model group, rat urinary mAlb(574.9±197.8)ng/ml,β2-MG(0.198±0.040)μg/ml, kidney AngⅡ(8 462.91±781.23)μm2 in Chinese medicine group, rat urinary mAlb(644.4±147.5)ng/ml, β2-MG(0.206±0.044)μg/ml, kidney AngⅡ(8 696.88±679.70)μm2 in lotensin group were significantly decreased(P<0.01); while kidney ACE2(1 904.02 ± 454.08)μm2 in Chinese medicine group, kidney ACE2(1896.11±445.43)μm2 in lotensin group was significantly increased(P<0.01). Conclusion Yishen-Pinggan decoction can reduce the SHR urinary microalbumin excretion so as to reduce high blood pressure early kidney damage; its role may be associated with its increasing local renal ACE2 expression and reducing the kidney Ang Ⅱ expression.

AIM　To study the direct effect of tyrphostin AG114 on recombinant human protein kinase CK2 holoenzyme and its kinetics. METHODS　Recombinant human protein kinase CK2 α and β subunits were cloned and expressed by genetic engineering, and purified to homogeneity. The two subunits were mixed at equal molar ratio and reconstituted CK2 holoenzyme, which exerted the maximum biological activity. The CK2 activity was assayed by detecting incorporation of 32P of ［γ-32P］ATP or ［γ-32P］GTP into the substrate in various conditions. RESULTS　The recombinant human CK2 was a second messenger (Ca2+, cAMP and cGMP) independent protein kinase, the characterization and function of the reconstituted holoenzyme were consistent with those of native CK2. AG114 strongly inhibited the holoenzyme activity of recombinant human protein kinase CK2 with an IC50 of 20.8 μmol·L-1, which lay between IC50 of 5,6-dichloro-1-β-D-ribofuranosyl-benzimidazole(DRB) and N-(2-aminoethyl)-5-chloronaphthalene-1-sulfonamide(A3), known as CK2 special inhibitors. Kinetic studies of AG114 inhibition on recombinant human CK2 showed that the inhibition was mixed competitive with GTP and noncompetitive with casein. CONCLUSION　AG114 not only is an effective inhibitor of protein tyrosine kinases, but also is a novel potent inhibitor of protein kinase CK2. The recombinant human protein kinase CK2 might be used as a molecular target for simpler screening method and development of more effective inhibitors of CK2.

To investigate the possibility to enhance resistance of human bone marrow cells to anticancer agents by transfection of mdrl gene. We transferred mdrl gene into human bone marrow cells with plasmid pHaMDR1/A containing human mdrl cDNA by Lipofectin.Pgp,mdrl gene expression product was detected by both flow cytometry and immunohistochemistry.Also,Pgp function was tested by efflux study using rhodamine.The resistance of human bone marrow cells to anticancer agents was assayed by color forming unit culture after exposure to Vincristine,Daunomycin, and Vp16.The results showed that mdrl gene was successfully transferred into human bone marrow cells, and it expressed.Biological activity of Pgp was confirmed by efflux study using rhodamine.Transferred human bone marrow cells possessed resistance to anticancer agents.It suggested that transfection of mdrl gene can increase resistance of human bone marrow cells to anticancer agents.

The current prevalence of myopia has been as high as 27.65%～53.80%among adolescents in Chinese schools.The major reasons are too much near-work activity and lack of outdoor activity for a long time.In order to reduce the prevalence of myopia in Chinese adolescents,we suggest that Chinese students should have 3.5 hours outdoor activity everyday,including 30 minutes travel between home and school,1 hour outdoor activity between classes,1 hour outdoor sport class at school,and 1 hour outdoor activity after school.

China is one of the countries where the prevalence rate of endemic fluorosis is very high.There are about one hundred million people suffering fluorosis.Many researchers are paying more and more attention to this field.Recently,some researches indicated that particular nutrients can influence fluorosis.This article reviewed the relationship between intake of protein and energy,mineral,vitamin and the occurrence and sequelae of fluorosis.
