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.

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 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.

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 .

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).

Objective: Pervious RT-PCR results revealed the possibility of effective regulation channel of Xiaoyao San in treating rats of syndrome of liver invading the spleen. This experiment was designed to explore CIS rats’ immunohistochemistry findings in hippocampal subregion CA1 and amygdaloid subregion BLA after suppressing both amygdaloid AMPA receptors by microinjection of CNQX. To compare Xiaoyao San group with CNQX group, and to analysis of these findings may prove the possibility of effective regulation channel of Xiaoyao san treating this syndrome. Methods: 75 male SD rats were randomly divided into 5 equal groups: normal group, CIS group, sham-operation group, CNQX group and Xiaoyao San group. The number of GluR2 positive cells in hippocampal subregion CA1 and amygdaloid subregion BLA in these 5 groups were examined by immunohistochemistry test. Results: Compared with control group, the number of GluR2 positive cells decreased in hippocampal subregion CA1. Statistical analysis showed that no difference existed in control, CNQX and Xiaoyao San groups in CA1 region. Except CNQX group, tendency of changes were contradictory in BLA and CA1 region. In addition, the least in BLA in CNQX group. This finding revealed that Xiaoyao San may act the same as CNQX, thus Xiaoyao San afforded effective protection against this depression syndrome through suppression of both amygdaloid excitability. Conclusion: The balance coordination between hippocampus and amygdala may be the key in transformation from adaption to damage in a state of stress, was one of the central mechanisms of liver governing smoothing qi flow (LGSQF) on regulating the stress. Xiaoyao San may effectively regulate the balance of the excitability of hippocampus and amygdala. This hypothesis may reveal the regulation channel on Xiaoyao San affording effective protection against liver invading the spleen syndrome.
