Objective To establish an equation of oxygen consumption in obese children and adolescents by multilevel linear model analytical method. Methods Sixty obese children and adolescents aged 11-16 years were randomly divided into the formula group(n=40) and back substitution verification group(n=20), with equal male and female. Subjects in formula group started exercise in the speed of 2km/h, increased lKm/h every 2.5 minutes till 8km/h, without gradient in treadmill and 80% HRmax was set as standard of exercise termination. Gaseous metabolism parameter and heart rate were measured for the set up of multiple linear regression equation of oxygen consumption. Back substitution verification was also made. Results Males' R~2 was 0.795 and females' R~2 was 0.75 in regression equation; oxygen consumption had a linear relationship (P0.001) with HR and LBM; The significance of variation coefficient and constants were obvious. The regression equation were set up as male:oxygen consumption(ml/min)=20.098xheart rate(bmp)+25.160×LBM(kg)-2935.835 and female: oxygen consumption(ml/min)=19.863xheart rate(bmp)+26.551×LBM(kg)-2675.676. The predictive value of oxygen consumption of the average relative error was 6.84%～8.72% in male, and 6.53%～8.23% in female. Conclusion The multiple regression equation of oxygen consumption with heart rate and body weight as independent variables might be applied in the calculation of the oxygen consumption of physical activity in obese children and adolescents.

Objective To investigate whether scores of epworth sleepiness scale (ESS) assessing daytime sleepiness were associated with sleep apnea syndrome(SAS)combined with cerebral vascular disease and ESS could be used to predict cerebral vascular disease occurrence.Methods A group of 62 SAS combined with transient ischemic attack(TIA), a group of 53 SAS with combined hypertension and the other group of 61 SAS combined without other diseases were monitored by polysomnography(PSG), daytime sleepiness of these SAS patients were assessed by ESS at the same time. Results Compared to SAS combined without other diseases, those SAS combined with TIA and hypertension patients had significant higher scores of ESS,apnea/hypopnea index (AHI) and micro-arousal index(MAI)(all P

Objective:To explore expression levels of Tim and TLR gene family in children with different types of mycoplasma pneumonia and their clinical significance.Methods: 56 patients with mycoplasma pneumonia were randomly selected in Ji′nan Maternity and Child Care Hospital from March ,2013 to March,2014.All the patients were divided into bronchopneumonia group ( n=40) and segmental pneumonia group (n=16) according to their X-ray manifestations.Bronchopneumonia group was characterized as dot,nodular increased density shadow with or without reticular ,stripe-like interstitial lesion.Segmental pneumonia was described as segmental or lobar consolidation of lung in X-ray.Meanwhile,30 healthy children were involved in control group with matched age and gender.Peripheral venous blood of all the children in every group was collected and total RNA was extracted .The mRNA of Toll-recepter 2,4 and Tim1,3 was quantified by quantitative real-time PCR (qRT-PCR),and compared between different groups.Results:The expression of mRNA of TLR-2,4 and Tim1 significantly increases in both bronchopneumonia group and segmental pneumonia group compared to healthy control.Meanwhile,the mRNA of TLR-2,4 and Tim-1,3 was significantly elevated among segmental pneumonia group compared to healthy control.In addition,the gene expression of Tim1,3 was higher in segmental pneumonia group than broncho-pneumonia group.Conclusion:The TLR-2,4 and Tim1 gene are over expressed in both types of mycoplasma pneumonia and Tim-1,3 are highly expressed in children with severe infection in lung.The expression alteration of TLR-2,4 and Tim1,3 gene is involved in different types of mycoplasma pneumonia.

Objective To compare the differences of cognitive dysfunction and hippocampal atrophy among patients with temporal lobe epilepsy (TLE) and healthy controls and probe into the relativity of cognitive dysfunction with hippocampal atrophy after temporal lobe epilepsy. Methods Forty-nine TLE cases and 20 healthy individuals were randomly selected. The WAMS-R and WAIS-R scales were adopted to assess the memory and intelligence of all the subjects. Hippocampal volumes were measured by semiautomatic measurement on the head magnetic resonance imaging (MRI). The degree of hippocampal atrophy (DHA) and asymmetry index (AsI) were caculated by adjusting hippocampal volumes and ratio of difference of two lateral hippocampal volumes. Results Compared with the healthy controls, not only did the TLE patients exhibit more memory deficits (83.2±21.0,t=-3.365 ,P=0.001 ), but also more fullscale intelligence (91.0±12.3, t=- 4.291, P=0.000). The bilateral hippocampi of all TLE patients significantly decreased in volume ( P=0.000 ) and increased in AsI ( t=3.975, P=0.000 ). The MQ of TLE patients was significantly negatively related to the duration of the illness ( r=-0.339, P=0.017 ). The bilateral DHA and the hippocampal AsI were negatively related to Z scores (left: r=-0.297, P= 0.038, right: r=-0.305, P=0.033, AsI: r=-0.441, P=0.002), repectively. Conclusions The more the DHA and asymmetry of bilateral hippocampi, the worse the cognitive dysfunction. The quantitative measurements of hippocampal volume could be used as a clinically effective factor for evaluating the decrease of the intelligence of TLE patients.

Objective: To explore whether vulnerable coronary plaques in HIV-infected patients are different with those in non-HIV-infected ones, and to analyze the relative risk factors. Methods: A total of 167 HIV-infected patients (HIV-infected group) and 185 non-HIV-infected patients(non-HIV-infected group) who underwent coronary CTA (CCTA) were collected. Vulnerable plaques were defined as those with two or more high-risk morphological features. The type, location and incidence of vulnerable coronary plaques were analyzed and compared between 2 groups, and the risk factors of vulnerable coronary plaques in HIV-infected patients were analyzed. Results: There was no significant difference of baseline clinical data between the two groups. The most common types of vulnerable coronary plaques in 2 groups were both low attenuation plaques+positive remodeling, most located in the proximal segment of left anterior descending artery (segment 6). The incidence of vulnerable coronary plaques ≥1 coronary segments in HIV-infected patients was higher than that in non-HIV-infected patients (34.73% vs 24.32%,P<0.05). Vulnerable coronary plaques in HIV-infected patients were independently correlated with the duration of antiretroviral therapy (ART) drug (OR=1.29, 95%CI [1.04,1.59], P=0.02). Conclusion: The incidence of vulnerable coronary plaques in HIV-infected patients was higher than that in non-HIV-infected patients. ART drug may be an independent risk factor for coronary plaque vulnerability in HIV-infected patients.

Objective To observe the modulatory effects of NF-κB on dynamic changes of TNF-α、IL-1β and ICAM-1 in rats with severe acute pancreatitis (SAP),and to assess the effects of pretreatment with mycophenolate mofetil (MMF) on them.Methods A total of 104 male Wistar rats were randomly divided into normal group,sham operation group,SAP group and MMF group.(1) In normal group,rats had just an incision on abdomen wall and sutured (n =8) ; (2) In sham operation group,rats underwent laparotomy with flipping over the pancreas and gendy striking five times by using blunt instrument and abdomen was closed (n =32); (3) In SAP group,SAP in rats was induced by the retrograde injection of sodium taurocholate (STC) into the pancreatic duct (n =32) ; (4) In MMF group,MMF (250mg/kg)was injected intraperitoneally one hours after injection of STC (n =32).Rats were saerificed by abdominalaorta exsanguination separately at intervals of 3,6,12 and 24 h after modeling of pancreatitis.Histologic score of pancreatic tissue was assessed,and serum amylase (AMS) and serum C-reactive protein (CRP)were measured by automatic biochemical detector.The serum levels of inflammatory cyctokines (TNF-α,1L-1β and 1CAM-1 ) were measured by using ELISA,and expression of NF-κB mRNA in pancreatic tissue was measured by using quantitative PCR.Results Compared with sham operation group,histologic score of pancreatic tissue,serum amylase,TNF-α、IL-1β and ICAM-1 in SAP group were increased significantly (P ＜ 0.05 ).Pretreatment with MMF obviously deceased histologic score,and the serum levels of amylase,TNF-α,IL-1β and ICAM-1 and the expression of NF-κB mRNA were higher than those in SAP group in early stage (P ＜0.05 ).Conclusions Cytokines play an important role in early stage of SAP.MMF could attenuate the severity of inflammatory response through inhibiting cellular immunity and modulating the proinflammatory cytokines produced.
