Hypertension in children is defined as systolic blood pressure and/ or diastolic blood pressure≥95th percentile for age,gender and height,on at least 3 occasions. Persistent hypertension despite non - pharmacologic measures should be treated with anti - hypertensive drugs. Angiotensin - converting enzyme inhibitors,angiotensin receptor blockers,calcium channel blockers,β - blockers and diuretics are safe,effective,and well tolerated in children. This article describes the selection and clinical application of anti - hypertensive drugs in children.

Mitogen-activated protein kinase (MAPK) s a serine/tyrosine kinase which s expressed widely and regulates various signal transduction pathways in mammalian cell. As one of the key branches of MAPK pathway, p38 MAPK signaling pathway plays an important role in various physiological and pathological processes, such as cell proliferation, differentiation, apoptosis and cell cycle regulation. In recent years, the research on p38MAPK signaling pathway in cell growth, metabolism and function of osteoclast, osteoblast and chondrocyte related to bone metabolism has attracted increasing attention. This article reviews the relationship beween p38MAPK and bone metabolism, in order to investigate the mechanism of action of p38MAPK in bone metabolism related diseases.

Objective:To observe the effects of gallnut water extract on the vitality of plaque biofilms.Methods:The oral plaque biofilms were obtained through bonding the enamel fragments to the bucca of the mindibular first molar for 24 h.The two groups of the biofilms were treated by gallnut water extract at 6 mg/ml and saline(control) for three minutes respectively.The effect of gallnut water extract on the vitality of plaque biofilms was observed by Ethidium bromide/Fluorescein diacetate (EB/FDA) staining and confocal laser scan microscope(CLSM).Results:All specimens had early biofilm formed,The percent vitality of the plaque biofilms treated with gallnut water extract and the control was 37.10?9.63 and 60.78?7.60 respectively(P

0.05 ). Conclusions With low initial FGF addition of N2O does not affect the uptake of desflurane. The low-flow desflurane anesthesia is safe and economical.

Objective To investigate the effects of short-term continuous subcutaneous insulin infusion (CSII) in newly diag-nosed type 2 diabetes mellitus(T2DM ) and to evaluate the treatment regimen conversion after CSII therapy .Methods 72 patients with newly diagnosed T2DM were treated with CSII for 2 weeks .Then they were randomly divided into two groups :the basal insu-lin group(glargine) and the oral anti-diabetic drug(OAD) group .Both groups were followed up for 2 years .Blood glucose ,insulin and HbA1c were measured before and after CSII and during the 2-year follow-up .Results CSII significantly controlled the glucose levels ,reduced the TG ,TC ,LDL levels and the homeostasis model assessment of insulin resistance ( HOMA-IR) and increased the homeostasis model assessment of insulin secretion (HOMA-IS)(all P< 0 .05) .During 1-year follow-up ,HbA1c in the glargine group and the OAD group was (6 .13 ± 0 .47)% and(6 .21 ± 0 .38)% respectively .During 2-year follow-up ,the HbA1c values in the two groups were (6 .91 ± 0 .57)% and(6 .43 ± 0 .62)% respectively .T HOMA-IR and HOAM-IS obtained the long tern improve-ment without significant body weight increase .Conclusion Short-term intensive insulin therapy can effectively control the blood glucose ,improve the sensitivity of insulin and the β-cell function ;after CSII ,adopting basic insulin and oral antidiabetic drugs can a-chieve the ideal glycemic control .

Objective To observe the effects of Sanhuangtangshenkang particles on the expression levels of tumor ne?crosis factor (TNF)-α, interleukin (IL)-6 in bone tissue of type 2 diabetic (T2DM) rat model. Methods There were seven groups of rats in this study. Ten female Wistar rats were used as control. Ten rats were established for osteoporosis model, and fifty rats were established for diabetic model. Fifty diabetic model rats were further divided into model control group, tra?ditional Chinese medicine (TCM) prevention group (high-dose TCM group, low-dose TCM group) and Western medicine group, with 10 rats for each group. All rats were given the corresponding intervention for 20 weeks. Automatic biochemistry analyzer was used to determine fasting blood glucose (FBG). ELISA was used to detect serum TNF-αand IL-6. Dual-energy X-ray absorptiometry (DXA) was used to assess bone density. Real-time PCR was used to appraise the mRNA of TNF-αand IL-6 in bone tissue. Western blot assay was used to measure protein expressions of TNF-αand IL-6 in bone tissue. Re?sults Compared with osteoporosis model group, bone density was significantly increased, serum levels of TNF-αand IL-6, the mRNA and protein expression level of IL-6 were significantly decreased in bone tissue of TCM groups and Western medi?cine group (P<0.05). The expression levels of TNF-αmRNA and protein were significantly decreased in bone tissue of in high-dose TCM prevention group and Western medicine group (P<0.05). Compared with the diabetic model group, the se?rum levels of FBG, TNF-αand IL-6 were significantly decreased in TCM groups and Western medicine group (P<0.05). The expression levels of TNF-αmRNA and protein were significantly decreased in high-dose TCM prevention group and Western medicine group (P<0.05). The mRNA and protein expression levels of IL-6 were significantly decreased in low-dose TCM prevention group and Western medicine group (P<0.05). Conclusion The expression levels of TNF-αand IL-6 are increased in serum and bone tissue of diabetic rats. Sanhuangtangshenkang particles can improve the inflammatorystate to play prevention and therapeutic effect on diabetic rats.

Ten compounds were isolated and purified by column chromatography over silica gel, preparative TLC, and Sephadex LH-20 from the whole plant of Solanum lyratum. The structures were elucidated on the basis of physico-chemical properties and spectral data as 1beta-hydroxy-1 ,2-dihydro-alpha-santonin (1) , boscialin (2) , blumenol C (3), 3beta-hydroxy-5alpha, 6alpha-epoxy-7-megastigmen-9-one(4), dehydrovomifoliol(5) , blumenol A(6), (1'S,2R,5S, 10R) -2-(1', 2'-dihydroxy-l1'-methylethyl) -6,10-dimethylspiro[4,5] dec-6-en-8-one(7) , (1'R,2R,5S,10R)-2-( 1',2'-dihydroxy-l '-methylethyl) -6,1 l0-dimethylspiro[4,5]dec-6-en-8-one( 8) , 2-(1',2'-dihydroxy-1 '-methylethyl) -6,1 0-dimethyl-9-hydroxyspiro [4,5] dec-6-en-8-one (9) , and grasshopper ketone (10). Compounds 1-10 were isolated from this plant for the first time.

Objective To test the potency of hepatitis B vaccine in China. Methods Two inbred strains(DBA/1 and BALB/c) and two NIH closes-colonies of mice were typed in the H-2 region by microcy-totoxicity method and PCR. Groups of mice of the tested strains were immunized with the same hepatitis B vaccine, the titre of anti-HBsAg antibody was analyzed by microplate, and the ED50 was then estimated by Karder method for each strain. Results Significant differences were found between potency estimates de-rived from assays using different strains of mice. Conclusion It is likely that the variation of immune re-sponse to hepatitis B vaccine in mice is correlative with the H-2 haplotype. In some special case, the bet-erozygosity in H-2 region found in NIH stock could influence the accuracy in such testing even a reference preparation of hepatitis B vaccine was used. Base on our experiment, to select an appropriate NIH stocks with the H-2q haplotype for potency testing of hepatitis B vaccine in China.
