RESUMO
Objective@#The aim of this study was to establish a comprehensive concise health index (CHI) for evaluating adolescents, so as to provide a basis for determining the overall health status of adolescents in China.@*Methods@#On the basis of a literature review and consensus among core researchers, adolescent CHI indicators in the following five dimensions were assessed:physical growth, physical fitness, common diseases, mental health and behavioral health. A total of 24 experts used an analysis hierarcgy process (AHP) to calculate the indicators subjective weights. In addition, from October to December of 2021, two regions, A and B were selected to conduct empirical research, and the CRITIC method was used to calculate the objective weights of the indicators. Finally, the weight coefficients were determined through the AHP-CRITIC combination weight method, and comprehensive evaluation was performed with the TOPSIS method.@*Results@#Across academic period and genders, the combined weighted coefficients of the health indicators were as follows:BMI, 0.081-0.095; waist circumference, 0.070-0.081; relative grip strength, 0.101-0.108; myopia, 0.110-0.128; dental caries, 0.055-0.070; psychological symptoms, 0.240-0.262; physical exercise, 0.085-0.115; screen time, 0.097-0.111; and sleep duration, 0.086-0.103. The health index of middle school students in city A (0.626±0.065) was significantly higher than that in city B(0.613±0.066)( t=6.34, P <0.01).@*Conclusion@#The comprehensive adolescent CHI evaluation method has good consistency and application value, and may serve as a reference for adolescent health monitoring.
RESUMO
Objective:To study the effect of Shenqi Fuzheng injection combined with interferon-α (IFN-α) on the expression of STAT1 gene in hepatocellular carcinoma cells,and to elucidate its mechanism of IFN-α synergistic effect.Methords:The effect of IFN-α injection alone or combined with Shenqi Fuzheng injection on the proliferation of MHCC97-L cells was detected by MTT assay.IFN-α was detected by Real-time PCR and Western-blot respectively.The expression of STAT1 mRNA and protein in the experimental group,the negative control group (NaCl) and the blank control group were determined,and the effect of Shenqi Fuzheng injection on the transcription and expression of STAT1 was determined.The expression of STAT1 in lentiviral vector MTT assay was used to detect the effect of IFN-α alone or in combination with Shenqi Fuzheng injection on the STAT1 gene silencing cells.The expression of STAT1 was detected by RT-PCR and Western-Blot in MHCC97L cells.Strain,on cell proliferation.Results:Compared with IFN-α alone,Shenqi Fuzheng injection combined with IFN-α enhanced the inhibitory effect of IFN-α on MHCC97-L (P＜0.01) and up-regulated the expression of STAT1mRNA and protein (P＜0.05).Successfully constructed the STAT1 gene silent in the MHCC97-L cell line.There was no significant difference in the inhibition rate of MHCC97-L between Shenqi Fuzheng injection and IFN-α (P＞0.05).Conclusion Shenqi Fuzheng Injection can up-regulate the expression of STAT1 in human hepatocellular carcinoma cell line MHCC97-L,so as to increase the effect of IFN-α.
