Atrial fibrillation (AF) is the most common arrhythmia,but its pathogenesis is still unclear.With the development of sleep medicine,obstructive sleep apnea (OSA) is found to associate with the occurrence of AF and recurrence after catheter ablation.This article reviews the pathophysiology of OSA,and relationship between OSA and the occurrence of AF,and its mechanism.It indicates that clinicians should pay close attention to the existence of OSA during diagnosis and treatment of AF.

Objective To observe the clinical therapeutic effect of Wenxintang in treating unstable angina pectoris. Methods Sixty patients of Yangqikuixu, Tanyuzuluo type suffered with unstable angina pectoris were randomly divided into two groups. 30 patients in the control group were treated with IsMo-20, Metoprolol and Aspirin, while another 30 patients in the treated group were treated with Wenxintang include the three medicines above. Each group was observed for 4 weeks respectively. Results The total effective rate in relieving angina in the treated group and the control group was 86.67% and 66.67% respectively, that in improving ECG changes was 69.23% and 47.82% respectively, the difference of the two parameters between the two groups was significant (P

OBJECTIVE:To improve the quality and efficiency of ADR monitoring in hospital for the convenience of reporters and ADR monitoring personnel.METHODS:Combined with the characteristics of hospital information system,computer technology such as network,ASP.NET programming language,SQL server 2005 database and data transformation were used to develop and apply ADR monitoring system based on hospital local area network.RESULTS:The ADR reporting quality has been improved and the quantity of ADR reports increased markedly and was kept stable.CONCLUSION:The system contributed to a informationalized and networking administration of ADR reporting,and it improved ADR reporting level thus deserving to be recommended.

0.05). No significant differences were detected in the median time of remission, median survival time and 1-, 2-year survival rates between the groups. Moreover, no significant differences were detected in the grade Ⅲ～Ⅳ leukopenia, grade Ⅲ～Ⅳ thrombocytopenia, grade Ⅲ～Ⅳ nausea and vomiting and grade Ⅲ～Ⅳ constipation between the groups. Conclusions:The response rate of the MVP regimen is slightly lower than the HMVP regimen, but the HMVP regimen is not noticeably superior. It may increase the toxicity such as leukopenia, nausea/vomiting and constipation, as wellas being more expensive. In short, MVP regimen should be selected between the regimens in the chemotherapy of advanced NSCLC.

Objective To investigate the relationship between the eosinophil (Eos) percentage and levels of eosinophil cationic protein (ECP) in induced sputum and the severity of late onset asthma(LOA) and differential diagnosis. Methods Fifty-four patients with LOA were selected. The percentage of eosinophil and levels of ECP were measured by Wrigbt′s stain and immuno-CAP system respectively. The lung function was also evaluated. The same indexes were measured in 25 elderly patients with chronic obstructive pulmonary disease (COPD) and 10 healthy elderly subjects as control. Results The percentage of Eos and levels of ECP in induced sputum in patients with LOA were significantly and negatively correlated with FEV_1/FVC (r=-0.68,-0.61, respectively, P

OBJECTIVE:To inverstigate the inhibitory effects of 14 kinds of traditional Chinese medicines on tyrosinase activity METHODS:The effective components of traditional Chinese medicines were extracted by 50% ethanol The speed of enzymic catalysis of tyrosinase was determined by ultraviolet spectrophotometry to evaluate the inhibitory effects of extracts of traditional Chinese medicines RESULTS:14 reactive time curves of enzymic catalysis of tyrosinase were obtained CONCLUS_ION:13 kinds of traditional Chinese medicines in vitro showed a better inhibitive effect on tyrosinase activity(P

Objective To investigate the role of spinal cord opioid receptors in the antinocieeptive effect of propefol in rats. Methods Male SD rats weighing 220-280 g were anesthetized with intraperitoneal chloral hydrate 300 mg/kg. Intratbecal (IT) catheter was placed at L5～6 interspace. Correct placement was confirmed by lower extremity motor block after injection of 2% lidocaine 15 μl via the iv catheter. Animals which were lame or paralyzed were excluded. Ninety SD rats in which IT catheters were successfully placed were randomly divided into 9 groups (n = 10 each): group Ⅰ propofol 10μg IT (P);group Ⅱ dimethyl suipbexide (DMSO-solvent for propofol) 5 μl IT (D);group Ⅲ artificial cerebral spinal fluid (ACSF) 5 μl IT;group Ⅳ propoful 10 μl + naloxone 15 μg IT (PN);group Ⅴ DMSO 5 μl IT + naloxone 15 μg IT (DN);group Ⅳ propofol 10μg IT + CTOP Ⅰμg IT (PC);group Ⅶ DMSO 5 μl IT + CTOP 1μg IT (DC);group Ⅷ propofol 10 μg IT + ICI 174, 864 1 μg IT (PI) and group ⅨDMSO 5 μl 1T + ICI 174, 864 1 μg IT (DI). In group Ⅳ-Ⅸ naloxone or CTOP (μ-receptor antagonist) or ICI 174, 864 (δ-receptor antagonist) was injected 5 min after propofol/DMSO. Pain threshold was measured before the first drug administration (T0) and at 10 min (T1), 20 min (T2) and 40 min (T3) after the first drug administration using hot water tail-withdrawal test. The latency for withdrawal of the tail from hot water was recorded. Results The pain threshold was significantly higher in group P, PN, PC and PI than in group D, DN, DC and DI respectively. The pain threshold was significantly increased at T1.2 compared with the baseline value at T0 in group P, PN, PC and PI. The pain threshold was significantly lower at T3 than at T1 and T2 in group P, PN, PC and PI. The pain threshold was significantly lower after drug administration in group PN and PI than in group P and PC. Conclusion Spinal cord δ-oploid receptors are involved in the anfinocicepfive effect of propofol.

Rosiglitazone was used for intervention of atherosclerosis in diabetic rabbits.The results showed that the intima/medium thickness ratio,cross section area of plaque,and the expressions of NADPH oxidase p22phox,gp91 phox were decreased;while the total anti-oxidative ability was increased after administration of rosiglitazone as compared with the non-intervention group(all P<0.05).Compared with rosiglitazone treatment group,serum hepatocuprein leveI in rosiglitazone prevention group was increased,while serum malonaldehyde level decreased(both P<0.05).This study suggests that rosiglitazone may have the effect of reducing the oxidative stress and the formation of atherosclerotic plaque in diabetics.

Objective To investigate the effects of Glibenclamide on reduction of secondary damage after acute spinal cord injury in rats.Methods Ninety rats were randomly divided into control group (laminectomy alone),spinal cord injury group(injury group),and treatment group(treated with Glibenclamide after spinal cord injury),with 30 rats in each group.The pathological morphology changes of injured spinal cord were observed by HE staining and electron microscope.The expressions of sulfonylurea receptor 1 (SUR1)were detected by immunohistochemical method at 45 min,6 h,24 h,3 d and 7 d after spinal cord injury,and IPP 6.0 software were used for quantitative analysis.The function recoveries of the hind limbs of rats were evaluated by BBB score.The blood sugar level was detected quantitatively.Results HE staining showed that tissue bleeding and microglia proliferation getting severe with time after spinal cord injury.Compared to the injury group,tissue bleeding,microglia proliferation and inflammatory cell invasion was less severe in treatment group.Showed by electron microscope,inflammatory cell invasion,myelin sheath layer structure damage and mitochondrial swelling were significantly reduced after Glibenclamide treatment.Detected by immunohistochemical staining,the expressions of SUR1 at all time points after injury,except for 45 min that there were no SUR1 expressions in all groups,were much weaker in the treatment group than in the injury group.The SUR1 expression reached the peak at 24 h after injury in injury group,and decreased gradually with time.Significant differences were found in the SUR1 expression among three groups by oneway ANOVE.The BBB scores of treatment group were significant higher than that of injury group.The blood sugar slightly decreased in the treatment group,while no significant difference was found among three groups.Conclusion Glibenclamide can significant reduced the secondary damage after acute spinal cord injury.The protection of Glibenclamide after spinal cord injury may relate to its suppression of SUR1.
