OBJECTIVE:To study the effects of mifepristone on the expression of inflammatory factors in endometriosis (Ems)model rats. METHODS:SD rats were randomly divided into normal group(normal saline),model group(normal saline), mifepristone low-dose,medium-dose and high-dose groups [0.65,1.30,2.60 mg/(kg·d)],with 10 rats in each group. Except for normal group,Ems model was induced in other groups,and they were given relevant medicine intragastrically for consecutive 4 weeks. The volume of the ectopic focus was compared before and after treatment. The serum contents of TNF-α,IL-6 and IL-8 were detected by ELISA method. The phosphorylation of NF-κB p65 and the expression of COX-2 and PGE2 were detected by West-ern blot. The expression of NF-κB p65 mRNA in ectopic focus was detected by RT-PCR. RESULTS:Compared with normal group,the volume of the ectopic focus,the serum contents of TNF-α,IL-6 and IL-8,the expression of COX-2 and PGE2 protein, the phosphorylation of NF-κB p65 and the expression of NF-κB p65 mRNA in ectopic focus were increased in model group(P<0.01). Compared with model group,the volume of the ectopic focus,the serum contents of TNF-α,IL-6 and IL-8,the expression of COX-2 and PGE2 protein,the phosphorylation of NF-κB p65 and the expression of NF-κB p65 mRNA in ectopic focus were de-creased in mifepristone groups(P<0.01),in dose-dependent manner. CONCLUSIONS:Mifepristone can reduce the volume of the Ems ectopic focus,via blocking NF-κB signaling pathway and reducing the expression of inflammatory factors.

OBJECTIVE: To investigate the effects of Baobaole oral liquid on neuronal excitability in lateral hypothalamic area (LHA) and ventromedial hypothalamic nuclear (VMN) in anorectic rats. METHODS: The anorectic rat model was established by feeding with special prepared forage for a week, and then Baobaole oral liquid, a liquid extract of a compound traditional Chinese medicine for activating spleen, was administered once a day for 3 weeks. Finally, extracellular recording from LHA and VMN neurons in rats were made in order to characterize their responses to gastric vagal nerve stimulation and intravenous injection of glucose in the normal, untreated, and Baobaole-treated groups. RESULTS: There was no statistical difference in response characteristics of LHA neurons to gastric vagal stimulation among 3 groups. The duration of VMN neuron excitation response to gastric vagal nerve stimulation in the untreated group was significantly longer than that of the normal control group (P<0.01), while the required stimulation intensity was significantly decreased (P<0.01). Moreover, among the neurons responding to the gastric vagal stimulation in the untreated group, the number of glycemia-sensitive neurons decreased in LHA and increased in VMN (P<0.01). The gastric vagal stimulation induced neuron responses in LHA and VMN of the Baobaole-treated group were not significantly changed as compared with the normal control group (P<0.01), and neither were the intravenous injection of glucose induced responses. CONCLUSION: Baobaole oral liquid can modulate the sensitivity of LHA and VMN neurons to the peripheral signal and make the coordination between LHA and VMN neurons in order to improve the appetite of anorectic rats.

Objective To investigate the preemptive analgesia therapy of dezocine on postoperative agitation in patients undergoing Esophagectomy under thoracoscopy.Methods Sixty cases of ASA Ⅰ,Ⅱ undergoing thoracoscopic resection of esophageal cancer patients were divided into two groups randomly:dezocine and control group,each group with 30 patients.Patients in dezocine group were intravenously injected with dezocine 0.1 mg/kg before intubation,and patients in control group just intubation as usual.The incidence of postoperative agitation in two groups were observed,and visual analog scale(VAS) score at 0 min,15 min,30 min and 45 min after extubation were registered.The time of wake up and extubatio,the change of hemodynamic were also recorded.Results The incidences of postoperative agitation in dezocine preemptive analgesia group were obviously lower than that in the control group (10％ (3/30) vs.60％ (19/30),P ＜0.01).The VAS score at 0 min,15 min,30 min and 45 min after extubation in dezocine preemptive analgesia group ((1.3 ± 1.2),(2.4 ± 1.7),(2.7 ± 1.3),(2.8 ± 1.2) points) were significantly lower than those in the control group ((3.4±1.5),(4.7±1.8),(5.0±1.6),(4.8±1.7) points) (F within group =18.6,P＜0.05; F between group =20.4,P ＜ 0.05 ; F interaction =20.0,P ＜ 0.05 ; compared different time between two groups,all P ＜ 0.01).Conclusion Preemptive analgesia with dezocine can obviously lessen postoperative agitation in patients undergoing Esophagectomy under thoracoscopy,and dezocine is also effective in postoperative analgesia.
