Clinical research of psychological intervention combined with celecoxib and physiotherapy on vertebral artery type of cervical spondylosis / 中国生化药物杂志

Objective To analyse effects of psychological intervention combined with celecoxib and physiotherapy on vertebral artery type of cervical spondylosis.Methods 134 patients with vertebral artery type of cervical spondylosis were grouped into two groups.Two groups were treated with physiotherapy and celecoxib,observation group was treated another with psychological intervention.Results Total efficiency of observation group was higher than that of control group(P<0.05).After treatment,symptom score,CASCS score,mean blood flow velocity in left vertebral artery and right vertebral artery,TNF-α and IL-6 level of observation group were better than that of control group(all P<0.05).During treatment, there was no obvious adverse reaction in the two groups.Conclusion Sychological intervention can improve the therapeutic effect of patients with cervical spondylosis of vertebral artery type.

Luteolin ameliorates endothelial dysfunction induced by oxidative stress / 中国临床药理学与治疗学

AIM: To evaluate the protective effect of luteolin on endothelial dysfunction induced by tert-butyl hydro-peroxide (t-BOOH). METHODS: We observed the effect of luteolin on t-BOOH-induced contractions in the aorta rings with or without endot helium, which were incubated with luteolin (10-6 to 10-4 mol/L) for 30 min before determining the concentration-response to t- BOOH. Cultured endothelial cell line (ECV304) was pretreated with different concentrations of luteolin (10-6 to 10-4 mol/L) for 30 min and then exposed to 10 -5 mol/L t-BOOH for 24 hours. Cell morphology was observed , and cell viability was determined by MTT assay. Meanwhile, RT-PCR was used to measure the expression of eNOS and COX-1. RESULTS: Increasing concentrations of t-BOOH produced concentration-dependent cont ractions in aorta rings isolated from rats, luteolin effectively attenuated the contraction in a concentration-dependent manner, and the relaxation response was greater in intact endothelium segments. In MTT and RT-PCR assays, luteolin effectively reduced the cytotoxicity of t-BOOH to endothelium cell and increased the expression of nitric oxide synthase (eNOS) mRNA, which was greatly down-regulated by t-BOOH. CONCLUSION: Luteolin effectively protects the endothelium from the impairment of oxidative stress, and the protection could be related to its negative modulation towards t-BOOH-induced contractions in the aorta.

Effect of laparoscopic cholecystectomy on systemic stress response / 中国普通外科杂志

Objective　To investigate the systemic stress responses of laparoscopic cholecystectomy(LC). Methods　Seventy patients with cholecystolithiasis were randomly divided into two groups: LC and open cholecystectomy(OC). Peripheral blood samples were obtained during the preoperative day and 1, 3, 5, 7 day after operation. Serum cytokines levels (TNF-α, IL-1β and IL-6) and C-reactive protein(CRP) were measured. Results　Changes of TNF-α and IL-1β before or after surgery in both groups showed no significant difference(P>0.05). Serum concentrations of IL-6 and CRP after surgery in both groups were significantly higher than those before surgery(P<0.05); but there were no significant difference between the two groups(P>0.05). Conclusions　The systemic stress responses of LC have no significant difference comparing with OC.
