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.

BACKGROUND: Real-time fluorescence quantitative polymerase chain reaction (PCR) refers to join the fluorescence groups into PCR reacting system, and to real-time monitor entire PCR process using the fluorescence signal accumulation, finally to make the quantitative analysis of the unknown template through the standard curve. OBJECTIVE: To study the theory of real-time fluorescence quantitative PCR and to explore its applications and progress in medicine. METHODS: With "real-time fluorescence quota PCR, theorem, application" in English for the search term, PubMed database was retrieved from January 2000 to December 2008. With "real-time fluorescence quantitative PCR, principle, application" in Chinese for the search term, Wanfang Database from January 2000 to December 2008, Tsinghua Tongfang Chinese database from January 2000 to December 2008 ware was retrieved. Literatures were limited to English and Chinese languages. Cell factor and tumor resistance genes served as the evaluation index. The methodology of research on the real-time fluorescence quantitative PCR technology and medical applied research on real-time fluorescence quantitative PCR technology were included. While repetitive research and Meta analysis were excluded. RESULTS AND CONCLUSION: Because real-time fluorescence quantitative PCR technology has not only realized PCR develops from qualitative to quantitative levels, but also has strong specificity, high sensitivity, good duplication, accurate quantization, high automaticity, and entire blocking response compared with conventional PCR, thus it becomes the important tool in the molecular biology research. Real-time fluorescence quantitative PCR technique has been widely applied, such as mRNA expression, detections of DNA copy number and determination of mononucleotide polymorphism, as well as in the clinical medicine including accurate quantitative examination of mycobacterium tuberculosis, Type B and Type C hepatitis, AIDS virus, gonococcus, and chlamydia trachomatis. Its quantitative scope extremely extends, no need of gradient dilution, the specificity is stronger, overcomes the false positivity. Due to the traditional PCR technology cannot give the accurate quantization, it is greatly limited in the practical application. Therefore, the accurate quantization of the PCR product, particularly the dynamic monitoring of viral etiology, becomes the urgent need.

Objective To investigate cardiac troponin I (cTnⅠ) for detecting minor myocardial damage and evaluating the prognostic value in unstable angina (UA) Methods Serum cTnⅠ, creatine kinase isoenzyme MB (CK MB) and a part in cardiac troponin T (cTnT) were measured in 106 (UA) and 44 stable angina (SA) patients as well as 68 cases with normal coronary angiography, 72 healthy subjects Relative risk factors and occurrence of heart events were analyzed Results 61 of 106 patients with UA had elevated cTnⅠ levels (57 5%), but 8 of 44 cases with SA had positive results (18 18%) Among them, only 3 cases had slightly elevated CK MB levels The incidences of heart events were significantly higher in patients with elevated cTnⅠ levels than in patients with normal one The higher cTnⅠ levels was and the more heart events occurred cTnT values was similarly found to be an indicator of increased risk of heart events Conclusion cTnⅠ is a higher sensitive and specific marker for assessing minor myocardial damage cTnⅠ is a strong independent indicator of risk stratification in UA
