BACKGROUND:SenseWear Pro Armband (SWA) is a monitoring device of physical activity energy consumption which consists of many kinds of motion sensors, and it has been widely used in the study of physical activity energy consumption in recent years. OBJECTIVE:To summarize the SWA accuracy, software version, time of wear as wel as its application in different populations and at different physical activity levels, for the purpose of providing some practical reference in the future usage of SWA. METHODS:A computer-based search of CNKI (ful-text database), PubMed and Web of Science databases was done for relevant articles published before January 2015 using the keywords of “physical activity, sensewear pro armband, energy expenditure, review” in Chinese and English, respectively. Articles published in core journals or SCI database were preferred. RESULTS AND CONCLUSION:Double labeled water method and indirect measurement method serve as standard criteria, and the relevant study shows that SWA has higher accuracy and can effectively evaluate the daily physical activity energy consumption. But under the special circumstances, there are some differences, such as different people and different exercise intensities. Meanwhile, to determine the appropriate wearing time and software version for data statistics are also one of the factors influencing the accuracy of the final result. SWA can accurately predict physical activity energy consumption, but for different populations and exercise intensities, it is necessary to improve the further calculation formula of SWA.

BACKGROUND:The current studies concerning the effect of obesity on children are limited to metabolic physiology, and there is little evidence available on skeletal muscle and motor ability.
OBJECTIVE:To compare isokinetic knee muscle strength between obese children and normal children, and analyze the causes of physical performance decline in obese children.
METHODS:A total of 56 children were recruited in this study, including 28 obese children and 28 normal children. The isokinetic muscle strength was tested by CON-TREX. The gaits were tested by VICON. The statistical analysis of al the differences between obese children and normal children were measured using SPSS 19.0 software.
RESULTS AND CONCLUSION:At the same gait speed, obese children had higher absolute peak torque and average power than normal children (P<0.05), but relative peak torque and relative average power showed no significant difference compared with normal children (P>0.05) except extensor group at 60(°)/s was significantly lower than normal children. At the same gait speed, the torque and power of extensor group were significantly higher than that of flexor group in the two groups (P<0.05);he obese children showed significant differences in the absolute peak torque and absolute average power compared with relative peak torque and relative average power of flexor group at 120(°)/s (P<0.05). In the two groups, the extensor exhibited higher torque in high speed, while the high flexor torque was found in low speed. Normal children had faster cadence and walking speed, significantly smal er step width and shorter stride time than obese children (P<0.05). Obese children have smal er relative strength and higher absolute strength than normal children;in addition, the low cadence and walking speed are found in obese children. These factors contribute to weak limb strength and insufficient motor ability.

Objective To detect the expressions of CXCR4,Smoothened (Smo) and Patched (Ptch) in breast cancer,to analyze the clinical significance of the expression of CXCR4,and to evaluate the relationships among CXCR4,Smo and Ptch.Methods The expressions of CXCR4,Smo and Ptch from 121 cases of breast cancer specimens were detected by immunohistochemistry,and the results were analyzed.Results The positive expression rate of CXCR4 in breast cancer was 66.9％,which was positively associated with the lymph node metastasis (r =0.181,P =0.044).The positive expression rates of Smo and Ptch in breast cancer were respectively 58.9％ and 64.5％.The expressions of Smo and Ptch were positively associated with the expression of CXCR4 in breast cancer (r =0.189,P =0.036 ; r =0.230,P =0.010).Conclusion The expression of CXCR4 in breast cancer is associated with the lymph node metastasis,and it is positiviely associated with the expressions of Smo and Ptch.Patients with breast cancer who express both CXCR4 and Hedgehog signaling pathway may have a higher risk of recurrence.

Objective To study the effect of grape seed procyanidin extract(GSPE) on the cell cycle arrest in human bladder cancer BIU87 cells and investigate the underlying molecular mechanism.Methods BIU87 cells were treated with different concentrations of GSPE(50,100 and 200 ?g/ml) and cultured for 24 h.The untreated group served as control.Flow cytometry was used to evaluate the cell cycle,and RT-PCR and Western blotting were used to detect the mRNA and protein expressions of CyclinD1 and cyclin-dependent kinase 4(CDK4).Results GSPE inhibited the cell growth through cell cycle arrest at G1 phrase in a dose-dependent manner.Semi-quantitated RT-PCR and Western blot analyses indicated that GSPE decreased CyclinD1 and CDK4 expressions in a dose-dependent fashion(P

Aim To investigate the molecular mechanism of Rosiglitazone on the expression of integrin ?1 in lung pulmonary carcinoma A549 cell line. Methods RT-PCR and flow cytometry methods were used to examine the expression of mRNA and cell total protein of PPAR? and integrin ?1 subunit. Results The expression of PPAR? mRNA and integrin ?1 mRNA had dose-dependent regulating action by Rosiglitazone,using PPAR? inhibitor GW9662 and ERK pathway inhibitor PD98059 could abolish the inhibition of PPAR? on the expression of integrin ?1. Conclusion The effect of PPAR? ligand Rosiglitazone on integrin ?1 expression is mediated through PPAR?-dependent signaling parthway. The mechanism may be partly involved in ERK pathway.

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 expolore the changes of coagulation index in newborns of different age and its clinical significance. Methods We studied 129 newborn infants without complication admitted to the neonatal department in an all-around hospital in Gnangzhou from January to December in 2005. These neonates were divided into two groups, including 63 cases of full-term infants and 66 cases of premature infants. Prothrombin time (PT), activated partial prothrombin time (APTT), Fibrinogen (Fg), thrombin time (TT), D-dimer (D-D) of these newborn infants were assayed on the first day, the third day and the tenth day. Results In the postnatal three periods of time, there was no difference in PT and D-dimer between two groups(P >0.05), but APTT and TT in premature infants were higher than that in full-term infants( P < 0.05), and Fg in premature infants were lower than that of full-term irfants(P<0.05). PT,APTT, TT,Ddimer were in decrease tendency and Fg increased as age increased( P < 0.05 ). Conclusion Geststional age and age had effect on coagulation index in newborn infants, and both can provide clinical references to clinical diagnosis and therapy.

Objective To analyze the mediating effect of mental resilience on the relationship between work stress and sleep quality in psychiatrists. Methods A total of 221 front-line psychiatrists from four mental health centers in Shannxi Province were selected as the study subjects using convenience sampling method. The questionnaires of Scale for Occupational Stressors on Clinician，Chinese Version of Connor-Davidson Resilience Scale and Pittsburgh Sleep Quality Index Scale were used to investigate the work stress，mental resilience and sleep quality of the psychiatrists. We conducted Bootstrap mediation test to analyze the mediating effect of mental resilience using SPSS PROCESS V3.5 macro program. Results The total score of work stress of psychiatrists was 97.0±17.5，and the medium（P25，P75）of mental resilience and sleep quality scores were 84.0（75.5， 94.0）and 6.0（5.0，9.0）respectively. The detection rate of sleep disorders among psychiatrists was 33.9%（75/221）. The total score of work stress of psychiatrists was negatively correlated with the total score of mental resilience ［rank correlation coefficient（rS ）=−0.34，P<0.01］，and was positively correlated with the total score of sleep quality（rS =0.48，P<0.01）. The total score of mental resilience was negatively correlated with that of sleep quality （rS = − 0.39，P<0.01）. The work stress of psychiatrists had a positive predictive effect on sleep quality［standardized regression coefficient（β）=0.41.P<0.01］，and a negative predictive effect on mental resilience（β）=−0.38，P<0.01）. Mental resilience had a negative predictive effect on sleep quality（β）=−0.24，P<0.01. Mental resilience played a partial mediating role between work stress and sleep quality，and the mediating effect accounted for 22.0% of the total effect. Conclusion Both work stress and mental resilience of psychiatrists can directly affect their sleep quality，and the mental resilience has a partial mediating role in the effect of work stress on sleep quality.
