Journal of Medical Research.2017;46(8):176-180. doi:10.11969/j.issn.1673-548X.2017.08.044

Objective In the study,the effect of berberine on Diabetic Nephropathy (DN) via oxidative stress was studied.Methods The DN model mice was administered with metformin (0.2g/kg),low-dose berberine (0.036 g/kg),middle-dose berberine (0.072g/kg) and high-dose berberine (0.144g/kg) for 8 weeks.After that,the fasting glucose,insulin,serum creatinine,urea nitrogen,Reactive Oxidative Species (ROS),Superoxide Dismutase (SOD),Kelch-like ECH-associated protein 1 (Keap1) 、Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and NADPH oxidase 4 (NOX4),24h urine protein,etc were measured.Results Berberine could significantly decrease the fasting blood glucose levels,increase the insulin production,and reduce the levels of 24 h urine protein,serum urea nitrogen,creatinine,improve SOD and Nrf2,decrease ROS,Keap1and NOX4.Conclusion Berberine has the protactive effects in DN mice via the Keap-Nrf2/ARE pathway,and middle/high-dose berberine was much better.The mechanism may be related to the alleviated of the oxidative stress.

Journal of Medical Research.2017;46(8):169-171. doi:10.11969/j.issn.1673-548X.2017.08.042

Objective To investigate the effect of head extension angle to glottis exposure by using three-dimensional CT reconstruction sagittal plane images of upper airway.Methods There were 80 patients,aged 7-78 years old,who had been scanned by helical CT in the head and neck.Reconstructed images were obtained by AW4.4 workstation and the following parameter was measured:angle α(A0 group),the angle created by the upper central incisor and root of epiglottis(angular vertex) and midpoint of glottis.Reconstructed images were printed according to the actual size of human body in a ratio of 1∶ 1,then the images were cut off from the upper central incisor to root of epiglottis by a section of arcs.Increasing the degree of angle α by clockwise to hypothetically increase the angle of head extension.The glottis was exposed by using a paper-made laryngoscope(Macintosh) model,and the success rate of glottis exposure was recorded when the degree of angle α was respectively increased 10°(A10 group),20°(A20 group),and 30°(A30 group).Results Compared with A0 group,the success rate of glottis exposure increased significantly in A10 group,A20 group and A30 group.The success rate of glottis exposure in A20 group and A30 group was significantly higher than A10 group.Compared with A20 group,the success rate of glottis exposure obviously increased in A30 group.Conclusion Based on CT reconstruction images of upper airway,we can analog study the effect of head extension angle to glottis exposure.

Journal of Medical Research.2017;46(8):132-134,138. doi:10.11969/j.issn.1673-548X.2017.08.032

Objective To compare the advantages and disadvantages of the two methods.Methods Thirty BALB/c mice were randomly divided into 3 groups:normal control group,OVA group and OVA/RSV group.With ovalbumin and hydroxide suspension sensitized,OVA nouse asthma model group and OVA/RSV group were established respectively by continuous atomization of ovalbumin and repeated nasal drops of RSV.The control group was established by sensitization and atomization excitation of sterile injection water.24 hours after the last stimulation,the lung function was measured.The cell sorting and counting in bronchoalveolar lavage fluid were performed.The pathological changes of lung tissue were observed by HE staining.Results Compared with the control group,the model groups have obvious symptoms of asthma,airway wall thickening,lumen stenosis and a large number of inflammatory cell infiltration.And pathological damage of lung tissue in OVA/RSV group was significantly increased,compared with OVA group.The enhanced expiratory pause (Penh)values of OVA/RSV group were significantly higher than those in group OVA (P ＜ 0.05),and the number of neutrophils,monocytes,lymphocytes and eosinophils in BALF were significantly higher than those in OVA group (P ＜ 0.05).Conclusion The establishment of asthma mouse model by OVA sensitization and RSV induction is a better way to simulate the human asthma pathogenesis.

Journal of Medical Research.2017;46(8):87-90. doi:10.11969/j.issn.1673-548X.2017.08.022

Objective To investigate platelet counts and acute obstructive suppurative cholangitis correlation analysis and possible influential factors.Methods Data of 117 patients from October 2012 to October 2015 treated in our hospital,of whom 57 with acute obstructive suppurative cholangitis and 60 with common acute cholangitis were analyzed retrospectively to explore whether there was a correlation between thrombocytopenia (100 × 109/L) and AOSC,then experimental and control groups were established according to thrombocytopenia in the AOSC patients.The patient's age,sex,previous biliary surgery,white blood cells(WBC) count after admission within 6h,the percentage of neutrophils (NEU％),calcitonin (PCT) were retrospectively analyzed to further explore the influence factors of thrombocytopenia in AOSC patients.Results By comparison with the common acute cholangitis group,thrombocytopenia in AOSC group had obvious difference (P =0.01).In experimental group,NEU％,PCT had statistical difference compared with those in control group (P ＜ 0.05),and the patient's age,sex,previous biliary surgery,white blood cells(WBC) after admission within 6h count had no statistical significance.The logistic multivariate regression analysis showed that,NEU％,PCT were the independent predictors.Conclusion Correlated with AOSC,thrombocytopenia can be valued as indicators of the severity of acute cholangitis.In AOSC patients,NEU％,PCT were independent predictors of thrombocytopenia.
