ObjectiveTo study the effects of dexamethasone local injection as an adjunctive therapy for Hashimoto thyroiditis (HT). Methods60 HT cases were equally divided into 2 groups at random. The patients in the control group were given euthyrpx while the patients in the treated group were injected dexamethasone in addition to the medicine used in the control group. The thyroid characters such as thickness, lymphocytic infiltration and changes of thyroid follicle were observed. The patients were followed up before treatment and 4, 12, 24weeks and 1 year after treatment. ResultsIn the treatment group, all thyroid glands turned significantly softer,and the mass became smaller compared with that in the control group. The pathology of thyroids indicated that lymphocytic infiltration decreased, local immune reaction was ameliorated, and no obvious hormone side effects were observed. ConclusionLocal use of dexamethasone can modify the structure and function of thyroid.

Objective:To investigate the effect of chronic ethanol consumption on sensory information transmission in the cerebellar molecular layer and reveal the mechanism of chronic alcoholism on sensory information transmission and integration in the cerebellar cortex.Methods:Fifty healthy male ICR mice aged 6-8 weeks were randomly divided into saline group(control group)and ethanol consumption group(alcohol group) according to the random number table, with 25 mice in each group.The mice in alcohol group were injected intraperitoneally with 20% ethanol daily, while the mice in control group were injected with the same dose of normal saline. All mice were injected intraperitoneally once a day for 28 days.Through electrophysiological technology, patch-clamp amplifier and data acquisition software were used to record the changes in cerebellar molecular layer field potential of mice in the alcohol group and control group induced by sensory stimulation.Clampfit 10.3 software was used to record and analyze the electrophysiological data. SPSS 22.0 software was used for statistical analysis. Paired t-test and one-way ANOVA were used to analyze the differences before and after treatment. Results:After giving the stimulation of wind blowing, the amplitude of P1 in alcohol group was significantly higher than that in control group ((121.31±3.5)%, (97.2±2.7)%; t=26.08, P<0.05), and the area under the P1 curve (AUC) of the alcohol group was significantly lower than that of the control group ((127.1±4.2)%, (102.2±3.5)%; t=22.95, P<0.05). There was no significant difference in N1 amplitude between the two groups (P>0.05). When L-NNA, an inhibitor of nitric oxide synthase, was perfused into the brain surface of mice, the amplitude of P1 in alcohol group was significantly lower than that before administration ((76.2±4.8)%, (103.5±3.6)%; t=22.60, P<0.05), but there was no difference of the amplitude of P1 before administration and after elution ((101.5±4.6)%) ( t=1.70, P>0.05). After the L-NNA was perfused, the AUC of P1 was significantly lower than that before administration((72.4±5.6)%, (102.7±2.66)% ( t=24. 58, P<0.05), and there was no significant difference between before administration and after elution( (100.6±3.5)%, t=1.81, P>0.05). When L-NNA was perfused into the brain surface of mice, the amplitude of P1 in control group was (104.3±1.6)% and it had no differences compared with before administration(102.2±5.6)%, t=1.84, P>0.05) and after elution(102.5±4.5)%, t=1.92, P>0.05). And the AUC of P1 in control group after perfused L-NNA had no differences compared with before administration(103.5±2.6)%, (102.5±4.6)%) and after elution((101.9±3.7)%, t=0.99, 1.81, both P>0.05). When the mouse brain surface was perfused with NO donor SNAP, the amplitude of P1 in the control group was significantly higher than that before administration( (128.2±3.4)%, (103.5±2.6)%; t=28.89, P<0. 05) and there was no difference between before administration and after elution( (105.4±4.2)% , t=1.93, P>0.05). The AUC of P1((125.4±4.4)%) was higher than before administration((104.3±4.6)% , t=16.60, P<0.05) and there was no difference between before administration and after elution(103.5±4.2)%, t=0.65, P>0.05). Conclusion:Chronic ethanol consumption significantly enhances the inhibitory response, and the enhancement of inhibitory components stems from the activation of the NO signaling pathway.

OBJECTIVETo find a potential link among ABO blood group, lipid profiles and coronary artery disease (CAD) and to estimate the effect size of connection using mediation analysis model.
METHODSA total of 898 consecutive patients undergoing coronary angiography were enrolled, and divided into CAD group and non-CAD group according to angiographic findings. According to ABO blood group, patients were divided into O blood group and non-O blood group, as well as A blood group and non-A blood group. Baseline characteristics among various groups were compared and the association of ABO blood group, CAD and lipid profile was explored.
RESULTSSubjects of blood type A had higher concentration of total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) compared with that of non-A type (TC: (4.43 ± 1.12) mmol/L vs. (4.18 ± 1.09) mmol/L, LDL-C: (2.79 ± 0.99) mmo/L vs. (2.59 ± 1.01) mmol/L, all P < 0.01). TC and LDL-C were significantly higher while high density lipoprotein cholesterol (HDL-C) and ApoA I levels were significantly lower in CAD group than in non-CAD group (TC: (4.36 ± 1.05) mmol/L vs. (4.13 ± 1.16) mmol/L, LDL-C: (2.61 ± 0.87) mmol/L vs. (2.47 ± 0.94) mmol/L; ApoA I: (1.38 ± 0.29) mmol/L vs. (1.45 ± 0.33) mmol/L; all P < 0.01). After adjustment for traditional cardiovascular risk factors, blood group A and TC remained significantly associated with the risk of CAD (OR = 1.88, 95% CI 1.280-2.774, P < 0.01; OR = 1.03, 95% CI 1.018-1.033, P < 0.01, respectively). Specially, mediation analysis indicated that 10.5% of the effect of A blood group on CAD was mediated by TC levels (P < 0.01).
CONCLUSIONOur data indicate that there is an association between ABO blood group, TC levels and risk of CAD. Around 10.5% of the effect of A blood group on CAD is mediated by TC levels.
