Association between nonalcoholic fatty liver disease and serum magnesium level in patients with type 2 diabetes mellitus / 中华全科医师杂志

Objective@#To investigate the association between nonalcoholic fatty liver disease (NAFLD) and serum magnesium level in patients with type 2 diabetic mellitus (T2DM).@*Methods@#Clinical data of 1 273 consecutive patients with T2DM admitted in hospital from June 2013 to June 2017 were retrospectively analyzed. According to the quartile of serum magnesium levels, patients were divided into 4 groups: Q1 group (≤ 0.79 mmol/L, n=376), Q2 group (0.80-0.84 mmol/L, n=296), Q3 group (0.85-0.89 mmol/L, n=287) , and Q4 group (≥0.90 mmol/L, n=314). Logistic regression was used to analyze the association between NAFLD and serum magnesium level.@*Results@#The average age of the study population was (56.4±13.8) years, males accounted for 52.7%(671/1 273), NAFLD patients accounted for 58.4%(743/1 273). The prevalence of NAFLD in Q4, Q3, Q2 and Q1 groups was 53.8%(169/314), 52.6%(151/287), 57.4%(170/296) and 67.3%(253/376), respectively (χ2=19.00, P=0.000). Logistic regression showed that compared with the Q4 group, OR(95%CI) for NAFLD in the Q1 group was 1.49 (1.03-2.16), Ptrend=0.011 after adjusting for age, sex, duration of diabetes, BMI, systolic blood pressure, alcohol consumption, TG, glycosylated hemoglobin and serum uric acid. After further adjusting for estimated glomerular filtration rate (eGFR), OR(95%CI) for NAFLD was 1.33 (0.92-1.94) and Ptrend=0.065 in the Q1 group compared with the Q4 group.@*Conclusion@#Reduction in serum magnesium is associated with an increased risk of NAFLD in T2DM patients, and eGFR may be a confounding factor.

The effect of 18β-sodium glycyrrhetinic acid on the nasal mucosa epithelial cilia in rat models of allergic rhinitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate 18β-sodium glycyrrhetinic acid impact on nasal mucosa epithelial cilia in rat models of allergic rhinitis (AR).@*METHOD@#AR models were established by ovalbumin-induction. Wister rats were randomly divided into groups as normal group, model group, budesonide (0.2 mg/kg) group and sodium glycyrrhetinic acid (20 mg/kg and 40 mg/kg) group after the success of AR models. At 2 weeks and 4 weeks after treatment, the behavioral changes of rats were observed and recorded, and nasal septum mucosae were collected after 2 week and 4 week intervention, and the morphological changes of nasal mucosae were observed by electron microscope.@*RESULT@#Model group developed typical AR symptoms, the total score in all animals was > 5. With budesonide and sodium glycyrrhetinic acid treatment, the AR symptoms were relieved, and the total scores were reduced significantly (P < 0.01). Compared with the model group: after 2 weeks' intervention, thick mucous secretions on the top of columnar epithelium cilia in rat nasal mucosa was significantly reduced, and cilia adhesion, lodging, shedding were relieved in budesonide group and sodium glycyrrhetinic acid group, the relieve in budesonide group was slightly better than that in sodium glycyrrhetinic acid group; after 4 week intervention, Cilia adhesion, lodging, shedding were completely vanished, and the cilia were ranged in regular direction in budesonide group and sodium glycyrrhetinic acid group. Cilia in sodium glycyrrhetinic acid (20 mg/kg) group was more orderly, smooth than that in budesonide group and sodium glycyrrhetinic acid group (40 mg/kg), and the condition of cilia in sodium glycyrrhetinic acid group (20 mg/kg) was similar to the normal group.@*CONCLUSION@#18β-sodium glycyrrhetinic acid is effective to restrain the pathological changes of nasal mucosa cilia in rat models of AR.

The effect of 18β-glycyrrhetinic acid on tight junctions of the nasal mucosa epithelial cells in rat models with allergic rhinitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To observe 18β-glycyrrhetinic acid (GA) impact on ultrastructure of tight junctions (TJs) of nasal mucosa epithelial cells in rats models of allergic rhinitis (AR).@*METHOD@#Ninety-six Wistar rats were randomly divided into control group, model group, loratadine group, and 18β-glycyrrhetinic acid group, and each group had 24 rats. Ovalbumin was used to establish a rat AR model. The behavioral changes and the tight junctions of nasal epithelial were observed and compared in different groups after 2,4,6 and 10 weeks intervention.@*RESULT@#The length of TJs in allergic rhinitis model became shorter, electron-high-density plasma membrane became thicker, number of the integration loci reduced and gap of TJs widened or even ruptured. With the consistent effect of allergens,the changes of TJs in the model group aggravated gradually,and the changes of ultrastructure of TJs in 18β-glycyrrhetinic acid group was relieved apparently compared to model group and even were close to the control model with time.@*CONCLUSION@#18β-glycyrrhetinic acid can recover the ultrastructure of the tight junctions of AR rat nasal epithelial cells.

Clinical evaluation of intraarterial thrombolysis in acute cerebral infarction / 介入放射学杂志

Objective To present a retrospective analysis of the clinical outcome in patients treated by local intra-arterial thrombolysis (LITT). Using urokinase for acute ischemic stroke of the anterior or posterior arterial circulation.Methods Twenty-six patients were treated with LITT using urokinase. The effects all patients were assessed by using angiography, brain CT and stroke scale before and after treatment. Results Among 26 patients, the complete reperfusion of blood vessel appeared in 7 and partial reperfusion in 11.The efficiency rate reached 78%.Conclusions Cerebral arterial thrombolysis with UK can improve neurologic function defect in 84% of patients with acute ischemic stroke after 15 days, suggesting one of the best ways for treatment.
