RESUMO
Objective:To investigate the effect of nonalcoholic fatty liver disease (NAFLD) on glucose and lipid metabolism during pregnancy.Methods:A retrospective analysis was performed in women who gave birth in Minhang Hospital Affiliated to Fudan University from January 2013 to June 2020. The data on demographic, clinical examination, and delivery were obtained via electronic medical record abstraction. According to the ultrasound imaging, all pregnant women were divided into NAFLD group and control group. The difference of glucose and lipid metabolism indexes, incidence of gestational diabetes mellitus, and gestational hypertension between two groups were compared. Logistic regression model was used to examine potential associations between NAFLD and metabolic related adverse pregnancy outcomes.Results:A total of 14 708 pregnant women with a mean age of (29.1±4.7) years and a mean body mass index of (21.0±2.8) kg/m 2 were included in our study. Of those eligible women, 554 (3.8%) were confirmed by ultrasound as NAFLD. Pregnant women with NAFLD presented higher circulating levels of fasting glucose [(4.2±0.5)mmol/L vs (4.1±0.5)mmol/L, P<0.01], 1 h plasma glucose [(7.4±1.7)mmol/L vs (6.6±1.6)mmol/L, P<0.01] and 2 h plasma glucose [(6.2±1.4)mmol/L vs (5.7±1.3)mmol/L, P<0.01] after glucose loading, HbA 1C [(5.2±0.4)% vs (5.1±0.5)%, P<0.01], triglyceride [(2.1±1.1)mmol/L vs (1.6±0.7)mmol/L, P<0.01], total cholesterol [(4.8±0.8)mmol/L vs (4.7±0.9)mmol/L, P<0.01], low density lipoprotein-cholesterol [(2.6±0.7)mmol/L vs (2.5±0.7)mmol/L, P<0.01], uric acid [(224.1±51.8)μmol/L vs (203.0±45.9)μmol/L, P<0.01] level. After adjusting for potential confounders, NAFLD significantly increased the risk of gestational diabetes mellitus ( OR=1.722, 95% CI 1.079-2.747, P=0.023) and gestational hypertension ( OR=3.845, 95% CI 2.247-6.582, P<0.001). Conclusions:Compared to non NAFLD, women with a diagnosis of NAFLD had more significant glucose and lipid metablic aberrations during pregnancy and increased incidence of gestational diabetes and gestational hypertension. Pregnant women with NAFLD should be closely monitored on glucose and lipid metabolism and blood pressure to prevent gestational diabetes mellitus and hypertension.
RESUMO
Objective To investigate the level of depression on interference suppression function in patients with coronary heart disease (CHD).Methods 15 CHD patients with major depression,21 CHD patients with mild depression and 24 CHD patients without depressive symptoms in the Affiliated Hospital of Weifang Medical University from May 2013 to March 2015 were selected to complete the Emotional Stroop task and record their accuracy and reaction time according to the Self-Rating Depression Scale (SDS) and Classification and Diagnostic Criteria of Mental Disorders in China-Third Edition(CCMD-3).Results ① The reaction time was longer (F(2,57) =71.97,P＜0.01)and the accuracy was lower (F(2,57)=8.78,P=0.04) in CHD with major depression group and CHD with mild depression group compared with CHD group.② The reaction time of negative words ((872.77±348.47) ms,(796.53±200.92)ms) was longer than positive words ((809.22±343.45)ms,(740.85±177.82)ms) in CHD with major depression group and CHD with mild depression group.③ The interference effect of negative words was bigger in CHD with major depression group and CHD with mild depression group ((35.48±181.97)ms,(7.16±200.06)ms) compared with CHD group ((-19.86± 177.82)ms).Conclusion Both CHD patients with major depression and CHD patients with mild depression have deficits in interference inhibition for negative information,which suggests that CHD with depressive individuals have impaired cognitive control function.
RESUMO
<p><b>BACKGROUND</b>SIRT3 is an important regulator in cell metabolism, and recent studies have shown that it may be involved in the pharmacological effects of metformin. However, the molecular mechanisms underlying this process are unclear.</p><p><b>METHODS</b>The effects of SIRT3 on the regulation of oxidative stress and insulin resistance in skeletal muscle were evaluated in vitro. Differentiated L6 skeletal muscle cells were treated with 750 µmol/L palmitic acid to induce insulin resistance. SIRT3 was knocked down and overexpressed in L6 cells. SIRT3, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) p65, c-Jun N-terminal kinase 1 (JNK1), and superoxide dismutase 2 (SOD2) were evaluated by Western blotting.</p><p><b>RESULTS</b>Over expression of SIRT3 increased glucose uptake and decreased ROS production in L6-IR cells as well as in L6 cells. Knock-down of SIRT3 induced increased production of ROS while decreased glucose uptake in both L6 and L6-IR cells, and these effects were reversed by N-acetyl-L-cysteine (NAC). Metformin increased the expression of SIRT3 (1.5-fold) and SOD2 (2-fold) while down regulating NF-κB p65 (1.5-fold) and JNK1 (1.5-fold). Knockdown of SIRT3 (P < 0.05) reversed the metformin-induced decreases in NF-κB p65 and JNK1 and the metformin-induced increase in SOD2 (P < 0.05).</p><p><b>CONCLUSIONS</b>Upregulated SIRT3 is involved in the pharmacological mechanism by which metformin promotes glucose uptake. Additionally, SIRT3 may function as an important regulator of oxidative stress and a new alternative approach for targeting insulin resistance-related diseases.</p>

RESUMO
[Summary] Type 2 diabetic rat model accompanied by insulin resistance was established by high fat/high glucose diet and streptozotocin.Following metformin treatment for 4 weeks,realtime PCR and Western blot were used to detect the expressions of SIRT3 mRNA and protein in skeletal muscle tissue,respectively.The results showed that insulin sensitivity,superoxide dismutase (SOD),and glutathione (GSH) levels were significantly reduced in diabetic group compared with the control group (P＜0.05),while methane dicarboxylic aldehyde (MDA) level was increased (P＜0.05),along with the decreased expressions of SIRT3 mRNA and protein in skeletal muscles (P＜0.01).After metformin treatment,the insulin sensitivity,SOD,GSH,and SIRT3 mRNA and protein levels were significantly increased (P＜ 0.05 or P＜ 0.01),while MDA level was decreased (P ＜ 0.05),suggesting that metformin may ameliorate insulin resistance via upregulating SIRT3 expression in skeletal muscles of diabetic rats.

RESUMO
Objective To study the impact of personality and coping style on postpartum depression.Methods 273 cases of postpartum women were estimated by Edinburgh Postnatal Depression Scale ( EPDS),NEO Five-Factor Inventory (NEO-FFI) and Trait Coping Style Questionnaire (TCSQ). With the SPSS11.5,t-test,correlation analysis and regression analysis were carried out for the collected data. Results 23. 1% of postpartum women suffered from depression. There were significant differences in personality traits and coping styles between postpartum depression group and normal group(P＜ 0. 01 ). There was a significant correlation in depression of postpartum and neuroticism, extraversion ( r = - 0. 409 ～ 0. 824 ), agreeableness of personality traits, coping styles.The personality traits was related to coping styles ( r = 0.260, - 0.445, - 0. 234,0. 375 , - 0.431 ). The extraversion, agreeableness of personality traits, negative coping style and positive coping style entered the regression equation of depression and can explain the 32.9% percent variance. Conclusion The extraversion, agreeableness of personality traits, negative coping style and positive coping style are important factors for postpartum depression.
RESUMO
Objective To study the role of coping styles in the relationship between coping resources and psychosomatic health in patients with asthma. Methods 184 adult patients with asthma were investigated with General Serf-Efficacy Scale (GSES), Internality, Powerful Others, and Chance Scale (IPC), Social Support Rat-ing Scale (SSRS), Defensive Style Questionnaire (DSQ), Trait Coping Style Questionnaire (TCSQ) and Short Form 36 Health Survey Questionnaire (SF-36). Results Significant correlation between self-efficacy (r=0.356),locus of control(Ir=0.208, Pr=0.341, Cr=-0.349) ,subjective(r=0.201) and objective(r=0.189)social support, immature and middle ( r = - 0. 257 ) defensive styles and coping styles ( PCr = 0.231, NCr =-0.505 ) with Mental Component Summary (MCS) was found (all P <0.05), but Physical Component Summary (PCS) was only related to self-efficacy( r=0. 175) ,chance(r=0.150),immature(r=-0.256) and middle de-fensive Styles and negtive coping styles (all P < 0.05). PCS (t = - 5.189) and MCS (t = - 6. 758) could be predic-ted effectively by negative coping style (all P<0.01). Moreover, self-efficacy, powerful others and the use of so-cial support could had an effect on the health of patients through negative coping style. Conclusion Negative coping style could not only have a direct effect on the health of asthma patients but also be a mediator between self-efficacy, locus of control, social support and the health of patients.
