Journal of Huazhong University of Science and Technology (Medical Sciences) 2007;27(2):161-3
The expression of c-met stimulated by high glucose in human renal tubular epithelial cells and the role of HGF/c-met system in diabetic nephropathy were examined. The proximal tubular epithelial cells were cultured in vitro under different conditions. MTT was used for the detection of cellular proliferation and RT-PCR was employed for measurement of c-met mRNA level. Our results showed that under different conditions, there were no significant differences in the proliferation of proximal tubular epithelial cells 12 h and 24 h after the culuture (P>0.05). The proliferation of proximal tubular epithelial cells showed a significant change 96 h after the culture and the cellular proliferation induced by hepatocyte growth factor (HGF) was very active (P<0.05). Moreover, no significant difference in the expression of c-met mRNA was found 12 h after the culture under different conditions (P>0.05), while 24 and 96 h after the culture, a persistent and significantly higher expression of c-met mRNA was found in HGF-induced proliferation. It is concluded that addition of exogenous HGF could inhibit the apoptosis induced by high-level glucose, promote the proliferation of proximal tubular epithelial cells, and induce the expression of c-met. Our study suggests that local up-regulation of HGF/c-met system plays an important role in the repair of renal damage in diabetic nephropathy.

Objective To study the therapeutic effect of Danshen injection combined with conventional therapy on children with recurrent asthmatic bronchitis. Methods A prospective study was conducted. Fifty-five children with asthmatic bronchitis admitted in People's Hospital of Henan Province from January 2012 to July 2014 were enrolled and randomly divided into a integrative Chinese and western medicine group(30 cases)and a conventional therapy group(25 cases);in the same period,18 healthy children having passed physical examinations were chosen as the healthy control group. In the conventional therapy group,rest,oxygen inspiration,anti-infection, fluid supplement and aerosol inhalation,etc. were given,while in the integrative Chinese and western medicine group,based on the similar conventional therapies,additionally Danshen injection 0.4 mL · kg-1 · d-1 was given,once per day for a total of 14 days. The wheezing remission time and the pulmonary rale extinction time were observed in the two patient groups,and the fractional exhaled nitric oxide(FeNO)content was investigated in the three groups. Results The wheezing remission time and the pulmonary rale extinction time of the integrative Chinese and western medicine group were obviously shortened compared with those in the conventional therapy group〔the wheezing remission time(days):2.3±0.8 vs. 5.2±1.1,the pulmonary rale extinction time(days):6.8±1.5 vs. 8.4±1.1,both P<0.01〕. The contents of FeNO in the integrative Chinese and western medicine group and the conventional therapy group before treatment were significantly higher than those in the healthy control group(×10-9:30.3±9.5,30.4±8.2 vs. 13.6±3.4,both P<0.01),but after treatment the FeNO levels of both patient groups were markedly lowered,and the degree of change in integrative Chinese and western medicine group was more significant(×10-9:18.6±4.7 vs. 24.0±6.8,P<0.01). Conclusion Danshen injection combined with conventional therapy can obviously down-regulate the FeNO content,alleviate the airway inflammation,effectively relieve the children recurrence of asthmatic bronchitis.

Objective To observe the effects of adenosine and adenosine receptor agonist on the expression of inter?leukin-18 (IL-18) in patients with unstable angina (UAP), and the mechanism of adenosine receptor agonists thereof. Meth?ods Fifteen UAP and 15 healthy volunteers were included in this study. The effects of adenosine and the selective adenos?ine receptor agonists on the expression of IL-18 were measured by enzyme-linked immunosorbent assay (ELISA). Results The lower concentration of adenosine (1-100μmol/L) increased the expression of IL-18 in UAP group;whereas the higher concentration of adenosine (1 mmol/L) inhibited the expression of IL-18. The adenosine A1 receptor agonist and A3 receptor agonist increased the expression of IL-18, while the adenosine A2a receptor agonist inhibited the expression of IL-18. There was no significant effect for A2b receptor agonist on the expression of IL-18. Conclusion The lower concentrations of ade?nosine can enhance the expression of IL-18 through adenosine A1 and A3 receptors in UAP. The higher concentrations of ade?nosine can inhibit the expression of IL-18 through adenosine A2a receptors. Adenosine can promote IL-18 expression in lower concentrations.
