Uncoupling protein, a protein that participates in proton transport in the inner mitochondrial membrane, has some physiologic functions such as regulating thermogenesis, maintaining body temperature, regulating energy balance and adenosine triphosphate production, controlling reactive oxygen species production, and restraining apoptosis. It takes part in the pathophysiological processes in a number of diseases. The article reviews the uncoupling protein gene, distribution and regulation, the roles in peripheral tissues and central nervous system, and its possible relationship with cerebral infarction.

The occurrence of stroke in patients and a variety of underlying diseases during the hospitalization are associated with the treatment, they often result in the aggravation of disease, poor prognosis, and medical disputes. Theoretically, the timeliness of diagnosis and treatment of in-hospital strokes are superior to those outside hospitals, but it still has the widespread delay in the actual diagnosis and treatment. This article reviews the possible causes and mechanisms of in-hospital stroke in order to raise awareness of prevention of in-hospital stroke, prevent and eliminate the potential risks of in-hospital stroke.

Objective:To study the radiotherapy sensitization of recombinant human endostatin in patients with cervical cancer.Methods:Sixty patients with advanced cervical cancer (stage ⅡB to ⅣA) from July 2017 to November 2018 in the Second Affiliated Hospital of Dalian Medical University were selected. The patients were divided into experimental group and control group according to random number table with 30 cases each. The patients in experimental group were treated with recombinant human endostatin combined with concurrent chemoradiotherapy, while the patients in control group only received chemoradiotherapy. The serum levels of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) were measured 1 week before treatment and 1 week after treatment, and short-term efficacy was evaluated 3 months after treatment.Results:The objective remission rate (ORR) and disease control rate (DCR) in experimental group were higher than those in control group: 93% (28/30) vs. 87% (26/30) and 97% (29/30) vs. 93% (28/30), but there were no statistical differences between 2 groups ( P>0.05). There was no statistically significant difference in the occurrence of adverse reactions between 2 groups ( P>0.05). Compared with that before treatment, the serum VEGF and bFGF after treatment were significantly lower, experimental group: (88.07 ± 37.53) ng/L vs. (227.27 ± 142.61) ng/L and (21.03 ± 5.75) ng/L vs. (38.34 ± 18.17) ng/L, control: (120.04 ± 81.22) ng/L vs. (197.34 ± 142.41) ng/L and (24.04 ± 7.29) ng/L vs. (39.78 ± 13.35) ng/L, and there were statistical differences ( P<0.01); after treatment, the serum VEGF and bFGF in experimental group were lower than those in control group, but there were no statistical difference between 2 groups ( P>0.05). Conclusions:For patients with advanced cervical cancer, recombinant human endostatin combined with concurrent chemoradiotherapy can further decrease the serum levels of VEGF and bFGF, improve the sensitivity of chemoradiotherapy, and enhance the short-term efficacy.

Objective To better understand students' professional perception,humanistic education status quo and their preference to different humanistic education methods.Methods Questionnaire was conducted for 990 undergraduate students (2006 grade- 2010 grade) at medical school of Shanghai Jiao Tong university.SPSS 17.0 statistical software was used to analyze results of the questionnaire.Results Nearly 45% students chose to major in clinical medicine out of personal interest.The identification of students for humanistic quality was lower than that for clinical knowledge and skills.More than 50% students believed doctors were with high humanistic quality and there was a gap between students′ action and their understanding of the medical career identity and medical humanistic cultivation.More than 50% students preferred activities that train medical and auxiliary skills.Nearly 67% students also showed a shallow reading habit from regular internet surfing.Conclusion The professional perception of medical students are influenced by both social and historical factors influence.The gap between understanding and action is a consequence of current humanistic educational system.The humanistic educational methodology should conform to the psychological and s~ial characteristics of contemporary students.

Objective To investigate the inttuenee of elevated fasting blood glucose(FBG)on left ventrieular ejection fraction(LVEF)after acute myocardial infarction(AMI).Methods The relationship between FBG(≥8-hour fast within 24 hours of admission)and LVEF in 161 patients with AMI was studied prospectively.Patients were grouped by FBG (group 1,FBG<6.1 mmol/L,group 2,FBG 6.1-6.9mmol/L,group 3.FBG≥7.0mmol/L).LVEF was measured at admission and at 30 days after AMI onset Results Compared with that of normal FBG(group 1),LYEF of elevated FBG(group 2 and group 3)was lower[for admission:(49.3±6.7)%,(45.8±7.4)% vs (52.4±7.7)%,P<0.05;for 30day8:(52.7±7.3)%,(49.2±7.2)% vs (55.8±7.4)%.P<0.05].ConclusionElevated FBG is associated with worse LVEF after AMI.

Objective To investigate the clinical features,etiology and risk factors of the inpatients with ischemic stroke in the Department of Cardiology.Methods The medical records of the inpatients with ischemic stroke and the inpatients in a control group were collected retrospectively.The demographics,vascular risk factors,clinical features,and other related factors were compared in both groups.Multivariate logistic regression analysis was used to analyze the independent risk factors for in-hospital ischemic stroke in the Department of Cardiology.Results A total of 2 789 inpatients in departments of cardiology were enrolled,and 26 of them (0.93%) had in-hospital stroke.One hundred thirty inpatients from 2 763 patients without in-hospital stroke were used randomly as control cases.The proportions of the inpatients of hypertension (73.08% vs.50.77% ; x2=4.348,P=0.037),atrial fibrillation (50.00% vs.15.38%; x2=15.56,P=0.000),infection (30.77% vs.7.69% ; x2 =11.304,P =0.003),smoking (46.15% vs.21.54% ; x2 =6.886,P =0.009),alcohol (26.92% vs.11.54% ;x2 = 4.233,P =0.040),previous stroke history (19.23% vs.4.61% ;x2 =7.062,P =0.008),and taking anti-hypertensive drugs (42.31% vs.21.54% ;x2 =4.985,P =0.026),as well as systolic blood pressure (143.43 ± 18.59 mm Hgvs.129.52 ± 23.52 mm Hg; t =3.209,P=0.003; 1 mmHg =0.133 kPa),diastolic blood pressure (88.77± 11.35 mm Hg vs.77.55± 14.60 mmHg; t=2.421,P =0.020),and homocysteine levels (19.27 ± 11.08 μnol/L vs.15.30 ±5.25 μmol/L; t =2.814,P =0.006) in the stroke group were significantly higher than those in the control group in the Department of Cardiology.Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio [OR] 3.310,95% confidence interval [CI] 1.207-9.076; P =0.020),infection (OR 3.270,95% CI 1.024-10.438; P =0.045),systolic blood pressure (OR 1.023,95% Cl 1.002-1.045; P =0.031),and homocysteine level (OR 1.089,95% CI 1.009-1.175; P =0.029) were the independent risk factors for in-hospital ischemic stroke in the Department of Cardiology.Conclusions Atrial fibrillation,infection,systolic blood pressure,and high homocysteine levels are the independent risk factor for in-hospital ischemic stroke in the Department of Cardiology.Active intervention and control these risk factors may have great significance for reducing its risk.
