OBJECTIVETo analyze the frequency of beta-fibrinogen (beta-Fg) gene -455G/A, -148C/T and 448G/A polymorphism, fibrinogen molecular reactivity and their association with plasma fibrinogen levels in health adults, myocardial infarction and cerebral infarction disease.

METHODSThe beta-Fg gene -455G/A, -148C/T and 448G/A polymorphisms were analyzed by restriction fragment length polymorphism (RFLP). Fibrinogen molecular reactivity was analyzed for the conversion kinetics of fibrinogen into fibrin by a computer assistant procedure. Plasma fibrinogen levels were determined by Clauss method.

RESULTSThe frequencies of -455A, -148T, 448A allele in health adults were 0.185, 0.194 and 0.192, in myocardial infarction disease 0.295, 0.318 and 0.307, in cerebral infarction disease 0.177, 0.193 and 0.182, respectively. The frequencies of -455A, -148T, 448A alleles in myocardial infarction disease were apparently higher than that of health adults. There were close linkage between -455G, -148C and 448G or -455A, -148T and 448A, the correspondence was over 98%. There are no differences in the plasma fibrinogen levels of the three polymorphisms in two genotype groups. The fibrinogen molecular reactivity was significantly increased in cardiocerebral vascular disease and related with plasma fibrinogen level.

CONCLUSIONThe three polymorphisms loci are strong linkage disequilibrium. There are no significant differences in the plasma fibrinogen levels of the three polymorphisms in two genotype groups. The frequencies of -455A, -148T, 448A alleles in myocardial infarction disease were apparently higher than that of health adults. It suggest that there was no association between beta-Fg gene -455G/A, -148C/T and 448G/A polymorphisms and plasma fibrinogen levels, but did in myocardial infarction disease. The fibrinogen molecular reactivity was significantly increased in cardiocerebral vascular disease and related with plasma fibrinogen level.

Objective:To investigate the value of ultrasound findings in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus and correlate it with clinical factors.Methods:A total of 535 patients with type 2 diabetes mellitus who received treatment in Taiyuan Second People's Hospital from January 2016 to June 2019 underwent color Doppler ultrasound examination (T2DM group). Vascular inner diameter, intima-media thickness, atherosclerotic plaque formation, lumen stenosis or occlusion, and hemodynamic characteristics were determined in patients with type2 diabetes mellitus compared with those in 107 patients with non-type 2 diabetes mellitus (non-T2DM group). These parameters were correlated with the course of the disease, blood glucose level, concomitant hypertension or not, and clinical Wagner grade.Results:The incidences of intima-media thickening, atherosclerotic plaque, stenosis, and occlusion of lower extremity arteries were 69.9%, 89.0%, 77.0% and 11.6% respectively, in the T2DM group, which were significantly higher than 41.1%, 78.5%, 72.0%, and 1.9% respectively in the non-T2DM group ( χ2 = 32.52, P < 0.001; χ2 = 8.76, P = 0.003; χ2 = 27.77, P < 0.001). With the prolongation of the course of T2DM, the incidence of arterial lesions in the lower extremities increased ( P < 0.001). The incidences of intima-media thickening, atherosclerotic plaque, stenosis, and occlusion of lower extremity arteries were significantly greater in the poor blood glucose control group and non-hypertension group compared with the good blood glucose control group and hypertension group (all P < 0.05). The degree of lower extremity arterial stenosis in T2DM patients was related to Wagner's grade. As the degree of stenosis increased, Wagner's grade increased correspondingly and significantly ( P < 0.001). Conclusion:Color Doppler ultrasound examination has an important value in evaluating lower extremity arterial lesions in patients with T2DM. The degree of arterial lesions in the lower extremities of T2DM patients is correlated with the course of the disease, blood glucose levels, concomitant hypertension, and clinical Wagner grade. Color Doppler ultrasound examination has an important clinical significance in evaluating the degree of vascular lesions and guiding early interventions in the clinic.

ObjectiveTo explore the beliefs and attitudes about sleep in patients with comorbid depressive disorder and insomnia， and to explore its influence on sleep quality. MethodsPatients with comorbid depressive disorder and insomnia （n=61） and patients with primary insomnia （n=62） who met criteria specified in the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） in Beijing Anding Hospital Affiliated to Capital Medical University were enrolled， meantime， another 64 healthy controls were recruited. All subjects were assessed using Dysfunctional Beliefs and Attitudes about Sleep （DBAS） and Pittsburgh Sleep Quality Index （PSQI）. Additionally， patients with comorbid depressive disorder and insomnia were evaluated using Hamilton Depression Scale-17 item （HAMD-17）. The PSQI and DBAS scores were compared among three groups using analysis of covariance， and multiple linear regression analysis was used to screen the factors affecting PSQI score in patients with comorbid depressive disorder and insomnia. ResultsCompared with healthy controls， higher scores of PSQI （t=18.932， 18.610， P<0.01） along with lower scores of DBAS （t=-5.561， -5.791， P<0.01） were observed in patients with comorbid depressive disorder and insomnia and patients with primary insomnia. Taking the PSQI score of patients with comorbid depressive disorder and insomnia as the dependent variable， statistically significant equations were generated using multiple linear regression analysis （F=14.095， R²=0.327， P<0.05）， and the predictive and control factors of sleep in DBAS and age were found to be the influencing factors of PSQI score in patients （B=-0.100， -0.279， P<0.05 or 0.01）. ConclusionCompared with the normal，depression patients with insomnia have more dysfunctional beliefs and attitudes towards sleep，and dysfunctional cognition may be the influencing factor of their sleep quality.

ObjectiveTo study the prevalence of depression and the related influencing factors among the frontline healthcare professionals in the prevention and control of risk of imported COVID-19 cases， so as to provide references for improving their mental health status. MethodsBased on Wenjuanxing platform， a total of 984 frontline healthcare professionals participating in the screening and treatment of imported COVID-19 cases in Beijing Xiaotangshan hospital were assessed using Patients’ Health Questionnaire Depression Scale-9 item（PHQ-9）. ResultsA total of 770 questionnaires were collected with a valid rate of 78.3%， among which 344 cases （44.7%） had depressive symptoms. Logistic regression analysis showed that great changes in work content （OR=2.206， P<0.01）， sleep deprivation （OR=2.359， P<0.01）， six hours or less of sleep （OR=2.032， P<0.05）， focusing on epidemic information more than 1 hour per day （OR=1.095， P<0.05） were risk factors for depression， and regular exercise （OR=0.473， P<0.01） was a protective factor for depression relief. ConclusionThe frontline healthcare professionals in the prevention and control of risk of imported COVID-19 cases suffer a high risk of depression， while measures including scientific shift system， adequate sleep， less attention to the epidemic， and regular exercise may be effective in maintaining their physical and mental health.
