ABSTRACT
Objective@#To explore the relationship among cognitive flexibility, depression and eating attitude of adolescents and the influencing factors of eating attitude.@*Methods@#A total of 1 231 subjects were assessed using general information questionnaire, Kutcher Adolescent Depression Scale 11 item(KADS-11), Cognitive Flexibility Inventory(CFI), Eating Attitude Test 26(EAT-26). Data were analyzed by independent sample t-test, univariate linear regression, spearman correlation analysis and Logistic regression.@*Results@#There were significant differences in EAT 26 among adolescents between genders and between those with or without depression(P<0.01). Statistically significant differences were observed in CFI, flexible control and KADS 11 among adolescents with or without eating disorders(P<0.01). The scores of EAT 26 was negatively correlated with CFI (r=-0.19, P<0.01) and flexible control(r=-0.23, P<0.01). And there was a significant positive correlation between EAT 26 and KADS 11(r=0.23, P<0.01). Female(OR=2.40, 95%CI=1.87-3.23), depression (OR=1.76, 95%CI=1.35-2.29) and poor flexible control (OR=1.94, 95%CI=1.48-2.54) were risk factors for eating disorders.@*Conclusion@#Female, individuals with depressive symptoms or with poor flexible control ability are more likely to have eating disorders which need more attention.
ABSTRACT
Objective To evaluate the effect of contrast medium on the renal function in patients with cerebrovascular disease accompanied by diabetes mellitus after receiving neuro - interventional therapy. Methods The clinical data of a total of 108 patients with cerebrovascular disease complicated by diabetes mellitus type 2, who were treated with neuro - interventional therapy during the period from March 2013 to March 2016, were retrospectively analyzed. The contrast dose used in interventional procedures was less than 250ml in each patient. The preoperative and 24 h -postoperative serum creatinine (sCr), serum cystatin C (Cys C) levels were determined, and based on the modification of dietary renal disease (MDRD) equation and Larsson equation the estimated glomerular filtration rates (eGFR) were separately calculated. Results Compared with preoperative values, the 24 h - postoperative mean sCr and Cys C levels were increased significantly (P=0. 001, P=0. 015 respectively), while the average eGFR rates were remarkably decreased (P＜ 0. 000 1 by using MDRD equation, and P=0. 021 by using Larsson equation). No kidney damage that needed to be treated occurred in all patients. Conclusion The contrast dose used in neuro - interventional procedures can cause decline of renal function in patients with type 2 diabetes mellitus. The combined determination of sCr and Cys C levels is helpful for the detection of contrast - induced changes in renal function as early as possible. The use of conventional dose of contrast agent in neuro - interventional procedures is safe for patients with type 2 diabetes mellitus. (J Intervent Radiol, 2018, 27:277-280)
ABSTRACT
Objective To investigate the effectiveness and safety in patients with largeartery occlusive acute cerebral infarction who received multi-interventional modes mainly with mechanical thrombectomy and its related factors affecting prognosis. Methods The clinical data of 56 patients with large artery occlusive acute cerebral infarction were analyzed retrospectively. The clinical characteristics (gender,age,and underlying diseases),timing of treatment (time from ictus to puncture,time from puncture to recanalization), multi-interventional mode therapies (intra-arterial thrombolysis,thrombectomy,balloon dilation,and stenting, etc. ),and distribution of offending vessels were observed. The modified Thrombolysis in Cerebral Ischemia Scale (mTICI)grade was used to evaluate revascularization. The National Institute of Health Stroke Scale (NIHSS)score was used to observe the neurological function at 24 h before and after procedures. The modified Rankin scale (mRS)was used to evaluate the prognosis at 3 months after procedure. The safety of the treatment was evaluated with operative complications (mainly symptomatic intracranial hemorrhage)and mortality. The patients were divided into either a good prognosis group (n = 34;mRS≤2)or a poor prognosis group (n =22;mRS≥3)according to the prognosis at 3 months after procedure. They were analyzed with univariate analysis. The factors influencing the prognosis were further analyzed with multivariate logistic regression analysis. Results (1)The recanalization rate in 56 patients was 78. 6%(n = 44),in which basilar artery was the highest,reaching 93. 8% (15 / 16),middle cerebral artery was 87. 0% (20 / 23). The NIHSS score at 24 hours was 10 ± 7,it was lower than 16 ± 6 on admission. There was significant difference (t =6. 401,P <0. 01). At 3 months,34 patients (60. 7%)had good prognosis,4 (7. 1%)died,and 8 (14. 3%) had symptomatic intracranial hemorrhage. (2)Multiple factor analysis showed that the high level of recanalization was a protective factor for good prognosis (OR,0. 465,95% CI 0. 267 -0. 809,P =0. 007). Diabetes was an independent risk factor for poor prognosis (OR,5. 535,95% CI 1. 101 -27. 835, P = 0. 038). Conclusion Acute large artery occlusive cerebral infarction treated with the intra-arterial multi-interventional modes may quickly and effectively restore intracranial blood flow. It has the characteris-tics of high recanalization rate and good prognosis,and the higher the level of recanalization,the better the prognosis. Diabetes is an independent risk factor for poor prognosis.
ABSTRACT
ObjectiveTo investigate the value of MR diffusion tensor imaging (DTI) of optic nerve in the estimation of optic nerve changes of primary chronic angle-closure glaucoma (PCACG).Methods Twenty-five patients with PCACG including monocular involvement in 4 patients and binocular involvement in 21 patients and involving 46 eyes in which 24 right eyes and 22 1eft eyes,and 20 normal volunteers were enrolled.Conventional MRI and DTI were performed on all subjects using Magnetom Tim 3.0 T MRI.Fractional anisotropy( FA),mean diffusivity ( MD),axial diffusivities ( λ ∥ ) and radial diffusivities ( λ ⊥ )were measured and then compared between patients group and control group and between left eyes and right eyes.Two independent samples t-test and paired t-test were used.ResultsOn conventional MRI,thinner optic nerve with vaginal cavity widened slightly was found in 8 optic nerves of 6 patients.The value of FA,λ∥,λ⊥ and MD of 24 right optic nerves in patient group was(0.27 ± 0.09) × 10-3,(2.30 ±0.26) × 10 - 3,( 1.55 ± 0.35 ) × 10 - 3,and ( 1.80 ± 0.31 ) × 10 - 3 mm2/s respectively and that of 22 left optic nerves was (0.24 ± 0.09) × 10-3,(2.25 ± 0.41) × 10-3,(1.61 ± 0.46) × 10-3,and (1.82 ±0.47) × 10-3mm2/s respectively.The FA of optic nerve in patient group was lower than that of control group (P ＜0.05 ),while the meanλ∥,λ ⊥ and MD values was obviously higher than control group (P ＜ 0.05).There was no significant difference between right and left optic nerves in patient gro up ( P ＞0.05).ConclusionsDTI could detect abnormality and provide information about the pathological process of optic nerve in patients with PCACG.
ABSTRACT
According as partial dog's physiological parameter observing in airtight cabin under normal air pressure, when the oxygen concentration is normal or low, tentatively estimate the important effect of oxygen concentration on dog's circulatory system and respiratory system, and then ascertain the vital significance of micro-circumstance regulating system to improving personnel's physiological function in cockpits and passengers' cabins of armoured vehicles, naval vessels, aircrafts, etc. Micro-circumstance regulating system under the conditions of airtight cabin is designed, a single-chip microprocessor 89C51, oxygen and carbon dioxide concentration transducers form its nucleus primarily, the function involve automatically monitoring and feedbackly regulating oxygen and carbon dioxide concentration all the time.
ABSTRACT
Local low oxygen pressure caused by low air pressure in the altiplano results in many physiological and neuropsychological problems. For people moving from low-altitude regions to the altiplano, monitoring and improving indoor air quality, enriching its oxygen content are effective measures to ameliorate sleeping quality, psychosis, work efficiency and general health. Ergonomics has a brilliant prospect in enriching oxygen content of indoor air in the altiplano.
