ObjectiveTo investigate the effects of different therapeutic methods on borderline hypertension with metabolic syndrome patients. MethodsNinety borderline hypertension with metabolic syndrome patients were divided into three groups by random digits table with 30 cases: control group,conventional therapy group and intensive therapy group. The control group was given regular observation, the conventional therapy group took drug according to the disease situation; and the intensive therapy group not only formulated the aim of therapy, but also received diet control, sport therapy, healthy education and drug therapy. After 1 year's follow-up, the patients' changes were compared. ResultsAfter 1 year's follow-up,the levels of FPG, 2 h PG, 24 h mAlb and IMT were significantly increased(P < 0.05 ), and the levels of other index had no significant changes (P> 0.05) in control group. The levels of FPG,2 h PG,TC and TG were significantly decreased and IMT was significantly increased(P <0.05), the levels of other index had no significant changes(P > 0.05 ) in conventional therapy group. The levels of SBP, DBP, PP, FPG, 2 h PG, TC,TG,hs-CRP,24 h mAlb and HOMA-IR were significantly decreased and HDL-C, ABI were significantly increased (P < 0.01 or < 0.05 ) in intensive therapy group. After treatment, the levels of ABI and H DL-C were significantly higher and SBP, DBP, PP,TG, hs-CRP, 24 h mAlb, HOMA-IR, IMT were significantly lower in intensive therapy group than those in conventional therapy group (P < 0.01 or < 0.05 ). ConclusionsDrug therapy is efficient in borderline hypertension with metabolic syndrome patients, and intensive therapy can obviously improve the insulin resistance, to control the developing of hypertension can delay the vascular

OBJECTIVETo explore the ability and mechanism of insulin-like growth factor 1 (IGF-1) induced bone mesenchymal stem cells (BMSCs) differentiation into cardiomyocyte-like cells (CLCs).
METHODSBMSCs were isolated and purified in vitro. BMSCs were treated with control medium and 15 ng/ml IGF-1 for 3, 7, 14 and 21 d, respectively. The expression of Troponin-T (TNT), Troponin-I (TNI) and pIGF-1R were detected by immunocytochemistry and Western blot. In another experimental setting, BMSCs were treated with control medium and 15 ng/ml IGF-1, IGF-1 antagonist I-OMe AG538 (300 nmol/L) and 300 nmol/L I-OMe AG538 + 15 ng/ml IGF-1 for 3 to 48 h, respectively. Phosphorylation status of ERK1/2 and AKT, the two downstream mediators of mitogen-activated protein kinase (MAPK) kinase and phosphatidylinositol 3-kinase (PI3K) pathways, were detected by immunocytochemistry and Western blot.
RESULTSAfter 3 to 21 d exposure to IGF-1, the expression of pIGF-1R, TNT and TNI were significantly higher in IGF-1 group than those in control group, pIGF-1R peaked 14 d (all P < 0.05). After 3 and 6 h treatment, the ratio of pAKT/AKT (0.17 ± 0.03) and pERK1/2/ERK1/2 (0.06 ± 0.03) were significantly downregulated in I-OMe AG538 group compared to control group (1.00 ± 0.05) (all P < 0.05). The ratio of pAKT/AKT (1.00 ± 0.07) and pERK1/2/ERK1/2 (1.00 ± 0.09) were significantly upregulated in IGF-1 group compared to control group (0.72 ± 0.05) (all P < 0.05), but the ratio of pAKT/AKT (0.31 ± 0.10) and pERK1/2/ERK1/2 (0.39 ± 0.04) were significantly downregulated in I-OMe AG538 group compared to control group (0.63 ± 0.05) (all P < 0.05), the value of gray scale of TNT (195.06 ± 5.98) and TNI (198.32 ± 3.46) in I-OMe AG538 + IGF-1 group were significantly upregulated than that in IGF-1 group for TNT (188.70 ± 5.35) and TNI (176.10 ± 4.96) (all P < 0.05).
CONCLUSIONSIGF-1 could induce BMSCs differentiation into CLCs in vitro by activating MAPK and PI3K signaling pathways.

OBJECTIVETo explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway.
METHODThe hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot.
RESULTThe rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group.
CONCLUSIONThe soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.

OBJECTIVETo explore the effect of Shugan Jianpi Recipe (SJR) on LXRα/FAS signaling pathway mediated hepatocyte fatty deposits in nonalcoholic fatty liver disease (NAFLD) rats.
METHODSTotally 75 SPF grade male SD rats were randomly divided into 5 groups, i.e., the normal control group, the model group, the Shugan Recipe (SR) treatment groups, the Jianpi Recipe (JR) treatment group, and the SJR group. Except rats in the normal control group, the NAFLD rat model was duplicated using high fat diet (HFD). SR (Chaihu Shugan Powder) was administered to rats in the SR group. JR (Shenlin Baizhu Powder) was administered to rats in the JR group. SJR (Chaihu Shugan Powder plus Shenlin Baizhu Powder) was administered to rats in the SJR group. Changes of liver fat were analyzed using automatic biochemical analyzer. Liver cells were separated by low-speed centrifugation. Their activities and purities were identify using Typan blue and flow cytometry (FCM). Expression levels of LXRα and FAS mRNA in hepatocytes detected by Real-time quantitative PCR. Expression levels of LXRα and FAS protein were detected by Western blot.
RESULTS(1) Pathological results showed in the model group, hepatocytes were swollen with nucleus locating at the cell edge after oil red O staining; unequal sized small vacuoles could be seen inside cytoplasm. Some small vacuoles merged big vacuoles. All these indi- cated a NAFLD rat model was successfully established by high fat diet. Pathological structural changes could be impaired to some degree in all medicated groups, especially in the SR group. (2) Compared with the normal control group, expression levels of LXRα and FAS genes and proteins obviously increased in the model group (P < 0.01). Compared with the model group, their expression levels were obviously down-regulated in the JR group and the SR group (P < 0.01, P < 0.05).
CONCLUSIONSLXRα/FAS signaling pathway was an important signaling pathway for mediating lipid metabolism disorders of NAFLD rats. SJR could make hepatocyte fatty deposits tend to repair by adjusting the LXRα/FAS signaling pathway in NAFLD rats, which might be one of important mechanisms for SJR to prevent and cure NAFLD.
