ABSTRACT
Objective To investigate the relationship between high sensitive C reactive protein(hsCRP) and monocyte chemotactic protein-1 (MCP-1) in patients with metabolic syndrome(MS).Methods Sixty-two patients with MS and 52 normal healthy individuals (NS) were recruited in the study.And the levels of hs-CRP and MCP-1 were detected by ELISA.The severity of Insulin resistance was calculated by homeostasismodel assessment of insulin resistance(HOMA-IR).The monocytes in blood were isolated,cultured and stimulated by different concentrations of CRP.MCP-lexpression of monocytes was measured by real-time PCR.Results Patients with MS displayed significantly higher serum levels of hs-CRP and MCP-1 compared with healthy control group [(80.26 ±35.52) nmol/L vs (3.12 ±2.55) nmol/L for hs-CRP,P ＜0.01 ; (15.35 ± 10.12) nmol/L vs (9.76 ± 6.15) nmol/L for MCP-1,P ＜ 0.05].There was significantly positive correlation between hs-CRP and MCP-1.Serum hs-CRP,MCP-1and insulin resistance index were positively correlated,respectively.In vitro experiments indicated that CRP could up-regulate MCP-1 expression of monocytes in a concentration-dependent way.When the concentration of CRP was 176nmol/L,the expression of MCP-1 could reach 105％ compared with non-stimulated group.Conclusion With the severity of the inflammatory response and enhanced insulin resistance,elevated serum CRP level may result in MCP-1 expression in patients with metabolic syndrome.
ABSTRACT
Objective: To observe the effect of representative formula of nourishing yin and invigorating the kidney(Liuweidihuang Granula) cooperating with Flixotide aerosol inhalation on the allergic airway inflammation of asthma rat models.Methods: Wistar rats were randomly divided into six groups.Except the norma1 control group,all the other 5 groups were sensitized by injecting into the abdominal cavity of the ovalbumin(OVA) together with aluminum hydroxide as adjuvants,2 weeks later followed by aerosolized OVA challenge to prepare the asthma models.From the eighth day of the experiment,in medication administration teams, rats were sprayed with Flixotide aerosol and given intragastric administration with Liuweidihuang Granula.The normal control group and the asthma model group were drenched with normal saline.Results: There was no difference between the groups given Liuweidihuang Granula and different dosages of Flixotide aerosol but the amount of IFN-? and IFN-?/IL-4 in BALF in the Liuweidihuang Granula cooperating with Flixotide aerosol group were higher than that in the model group(P
ABSTRACT
OBJECTIVE: To study the photostability of the levofloxacin hydrochloride injection. METHODS: The content of levofloxacin hydrochloride was determined and its UV spectra changes were observed after being lighted by three different light sources-the UV light, the sunlight and the natural light for different periods of time. Whether there is any decomposed product or not was determined by TLC. RESULTS: There were decompositions of levofloxacin hydrochloride injection subjected to illumination from three light resources, with that under the sunlight decomposed faster; Rf value under TLC of the decomposed product was found to be 0.72. CONCLUSION: Levofloxacin hydrochloride injection should be kept away from UV light, the sunlight and the natural light.
