AIMTo study the stereoselectivity in O-demethylation of trans tramadol.

METHODSWith or without quinine and quinidine as inhibitors, rat liver microsomes were incubated in vitro with the enantiomers or the racemate of trans tramadol. The concentrations of the enantiomers of trans tramadol and O-demethyltramadol in the incubates were determined by high performance capillary electrophoresis. The O-demethylation processes were assayed by using the enzyme kinetic analysis method.

RESULTSAfter incubation, the concentrations of (-)-O-demethyltramadol were higher than those of (+)-enantiomer in all rat liver microsomal incubates. Enzyme kinetic analysis showed that the Km of the formation of the enantiomers of O-demethyltramadol were similar; The Vmax and Clint of the formation of (-)-O-demethyltramadol were significantly higher than those of the formation of (+)-enantiomer. When the racemate of trans tramadol was used as the substrate, there was interaction between the two enantiomers. The Km of the formation of the enantiomers of O-demethyltramadol increased, the Vmax of the formation of (+)-O-demethyltramadol decreased, the Vmax of the formation of (-)-O-demethyltramadol increased slightly. The O-demethylation of the enantiomers of trans tramadol was shown to be inhibited competitively by quinine and quinidine. The Ki of quinine and quinidine were 1.6 and 10.8 mumol.L-1 to the formation of (-)-O-demethyltramadol, 0.8 and 3.4 mumol.L-1 to the formation of (+)-O-demethyltramadol, respectively. Furthermore, quinine and quinidine were found to have stereoselective inhibition on the formation of O-demethyltramadol, both mainly inhibited the formation of (+)-O-demethyltramadol.

CONCLUSIONThe O-demethylation of trans tramadol was found to be stereoselective in rat liver microsomes in vitro, preferentially metabolized (-)-enantiomer. The stereoselectivity could be influenced by the interaction between the two enantiomers and the enzyme selective inhibitors.

Objective To assess the clinical predictability of waist-to-hip ratio (WHR) among female civil servants who had experienced risk factors of cardiovascular disease. Methods Data was gathered from 4153 female civil servants aged 21-91 y working at universities who were enrolled in health screening centre at the Second Hospital Attached to Hebei Medical University, in 2006. WHR quartiles were determined as: <0.80, 0.80-<0.84, 0.84-<0.90 and ≥0.90. Subjects were placed into high-risk categories for cardiovascular disease on the basis of national health reference on range norms of protocol including hypertension, diabetes mellitus and dyslipidemia. Results Participants had an increased likelihood of hypertension (systolic blood pressure) , dyslipidemia (elevated triacylglycerol and descending HDL-C) and diabetes mellitus at WHR≥0.84. All aforementioned variables had a significant odds ratio at WHR ≥0.84. This trend was further persisted after adjustment had been made on smoking, age, and BMI. Descended HDL-C was observed at the 0.80≤WHR<0.84 when compared with WHR< 0.80. Conclusion These data indicated an upward shift in the critical threshold for WHR to ≥0.84. Above which point, there was an elevation of risk factors on cardiovascular diseases among all the female civil servants. The trend persisted regardless of smoking, BMI

BACKGROUND:Pain mechanisms in patients with lumbar disc herniation are associated with inflammation,autophagy is closely related to intervertebral disc diseases and inflammatory response,and aberrant miR-206 expression can trigger skeletal diseases. OBJECTIVE:To investigate the mechanism of miR-206 on inflammation,analgesia and autophagy related proteins in nucleus pulposus in rats with lumbar disc herniation. METHODS:Sixty SPF male Sprague-Dawley rats were randomly divided into control group,model group,miR-206 mimics-NC group,miR-206 mimics group,miR-206 inhibitor-NC group and miR-206 inhibitor group.Animal models of lumbar disc herniation were established except for the control group.Ten days after modeling,miR-206 mimics-NC group,miR-206 mimics group,miR-206 inhibitor-NC group and miR-206 inhibitor group were injected with miR-206 mimics-NC(20 μmol/L,10 μL),miR-206 mimics(20 μmol/L,10 μL),miR-206 inhibitor-NC(20 μmol/L,10 μL)and miR-206 inhibitor(20 μmol/L,10 μL),respectively.Administration was given once a day for 4 continuous days.The control group and model group were injected with the same dose of normal saline.The paw withdrawal mechanical threshold of bilateral hind feet was measured by Von Frey filaments,and the paw withdrawal thermal latency of bilateral hind feet was measured by heat pain tester.The morphology of dorsal root ganglia was observed by hematoxylin-eosin staining.The expressions of inflammatory factors phospholipase A2,cyclooxygenase 2,prostaglandin E2,tumor necrosis factor α,and interleukin 1β in nucleus pulposus were detected by qPCR.The expressions of autophagy-related proteins LC3I and Beclin-1 were detected by western blot assay. RESULTS AND CONCLUSION:At 3,7,and 14 days after modeling,the paw withdrawal mechanical threshold and paw withdrawal thermal latency were both decreased in the model group compared with the control group,while the levels of phospholipase A2,cyclooxygenase 2,prostaglandin E2,tumor necrosis factor α,interleukin 1β,LC3I and Beclin-1 increased(P<0.05).The above indexes showed no significant changes in the miR-206 inhibitor-NC group and miR-206 mimics-NC group compared with the model group(P>0.05).Compared with the miR-206 mimics-NC group,the miR-206 mimics group had lower paw withdrawal mechanical threshold and paw withdrawal thermal latency and higher levels of phospholipase A2,cyclooxygenase 2,prostaglandin E2,tumor necrosis factor α,interleukin 1β,LC3I,and Beclin-1 levels(P<0.05).Compared with the miR-206 inhibitor-NC group,the rats in the miR-206 inhibitor group showed opposite changes in the above indicators,and there were significant differences between the two groups(P<0.05).To conclude,inhibition of miR-206 can significantly improve the level of inflammatory factors in nucleus pulposus of rats with lumbar disc herniation,increase pain threshold,and reduce autophagy.The mechanism is related to the inhibition of LC3I and Beclin-1 expression.
