Adoptive immune cells can regulate and strengthen immune function of cancer patients,thus effectively inhibit tumor escaping.Cytokine induced killer cells (CIK),natural killer cells (NK),tumor infiltrating lymphocytes (TIL),dendritic cells (DC),T cell receptor-modified T cells (TCR-T) and chimeric antigen receptor-modified T cells (CAR-T) eliminate tumor by killing tumor cells directly or stimulating the immune response against tumor cells through different mechanisms.

Aim: To investigate the analgesic effect of the new triazole compounds Ⅱ_3 and effects on cycloxygen-ase-1(COX-1) as well as cycloxygenase-2( COX-2). Methods: The hot plate and the stretching settings in mice were utilized to study the effects of compounds Ⅱ_3 on acute pain. Radioimmunologic kits were used to assay the contents of PGE_2 in macrophage and 6-keto-PGF_(1α) in endodermis, which represents the activities of COX-2 and COX-1, respectively. Results: CompoundsⅡ_3( 15,30,60 mg/kg) prolonged the pain liminal value and the writ-hing response time in the initial appearance, and reduced the frequency of the writhing response in 15 min after exposure of the mice to glacial acetic acid( P < 0. 05, P < 0. 01). CompoundsⅡ_3, at the concentrations of 1×10 ~(-5),1×10 ~(-6), and 1×10 ~(-7) mol/L, markedly inhibited the production of PGE_2 in macrophage, and also impeded the activity of COX-2 at 1×10 ~(-6) mol/L But the inhibition of 6-keto-PGFla in endodermis using the same settings of compounds Ⅱ_3 was found to be limited. Conclusion: CompoundsⅡ_3 has analgesic effects on the acute pain and selective inhibition on COX-2.

Objective To investigate the relationship of resting heart rate (RHR)and dyslipidemia in the elderly.Methods 3 919 cases of cerebrovascular disease risk factor screening in Renqiu permanent residents aged 60 -70 years were selected,excepted cases of atrial fibrillation and hyperthyreosis and received lipid -lowering and slowing the heart rate drugs as the research subjects,mean age 64(62,67)years,the rates of male and femal were 44.0% and 56.0% respectively.They underwent face -to -face health questionnaire,blood pressure and RHR meas-urement,anthropometric and laboratory tests.According to the RHR,they were divided into four groups:RHR1:<60 times/min,RHR2:>60 times/min and <70 times/min,RHR3:>70 times/min and <80 times/min,RHR4:>80 times/min.The effect of RHR on dyslipidemia was analyzed by multivariate logistic regression analysis.Results The high TC,TG,and the prevalence of high LDL -C increased gradually with heart rate,the differences were statisti-cally significant (all P <0.001).The prevalence low HDL -C and HDL -C levels had no obvious statistically differ-ences.TC,TG,and LDL -C and RHR were positively correlated.RHR1:<60 times/min was set as control group,the correction of gender,age,smoking,drinking,lack of physical activities,hypertension,diabetes,coronary heart disease, stroke or TIA,overweight,abdominal obesity,systolic pressure,diastolic blood pressure,fasting plasma glucose,insu-lin,uric acid,high TC in 60 -70 times/min,70 -80 times/min,and the risk of more than 80 times/min,respectively (OR =1.304,95%CI:0.983 -1.73),(OR =1.579,95%CI:1.195 -2.088),(OR =1.677,95%CI:1.258 -2.237).Conclusion The RHR and the prevalence of dyslipidemia is related,medical workers need to know the rela-tionship between RHR and dyslipidemia,increase the focus on RHR and intervention,in order to effectively control the occurrence of dyslipidemia and cardio -cerebrovascular disease,especially cholesterol heighten.

Objective To investigate the correlation between invasion ability and cytoskeleton remodeling of hepatocarcinoma cell by atomic force microscopy (AFM) and to explore mechanical properties during genesis,development and invasion of hepatocellular carcinoma (HCC).Methods Four HCC cell lines (MHCC-97H,MHCC-97L,SMMC-7721 ,Huh-7 )with different invasive ability were studied.Mechanical parameter (Young′s modulus)was measured by AFM.The pattern of cytoskeleton remodeling of HCC cell lines with different invasive ability was detected by immunofluorescent staining. The difference of cell invasive ability was tested by cell scratch experiment in other to verify mechanical data.Kruskal-Wallis H test was used to compare the differences between groups.Results The results of AFM indicated that Young′s modulus of cytoplasma area and nucleus area decreased gradually as cell invasion ability increased (χ2 =472.78,622.43,both P <0.01).According to invasive ability from low to high,Young′s modulus of cell cytoplasm area of Huh-7,SMMC-7721 ,MHCC-97L and MHCC-97H were 1 602.43 (845 .48,3 317.25)Pa,1 055 .28 (367.48,2 280.77)Pa,1 026.78 (369.20,2 019.96)Pa and 503.12 (366.11 ,700.31)Pa,respectively.Young′s modulus of cell nucleus area of Huh-7,SMMC-7721 ,MHCC-97L and MHCC-97H were 2 823.98 (1 262.78,4 440.07 )Pa,1 313.43 (590.71 , 2 678.62)Pa,1 285 .17 (583.29,1 961 .19)Pa and 655 .57 (441 .29,943.39)Pa,respectively.The results of immunofluorescent staining showed that the stronger the cell invasive ability,the worse cytoskeletal integrity and more irregular cell microfilament distribution. In cell scratch assay, the migration rate of MHCC-97H was 46.67% in 24 h and 86.47% in 48 h,that of MHCC-97L was 45 .70%in 24 h and 82.86% in 48 h,that of SMMC-7721 was 39.41 % in 24 h and 79.85 % in 48 h and that of Huh-7 was 34.60% in 24 h and 72.09% in 48 h,which showed that the cell migration orderly in creased as the cell invasion ability increased.Conclusions It seemed that HCC with higher invasive ability had lower Young′s modulus,softer cell,stronger deformability,worse cytoskeleton integrity and more irregular cell structure,and vice versa.

Objective To investigate the potential relationship between neck circumference and obesity related indexes and metabolic disorders associated with insulin resistance.Methods A random cluster sampling method was used to identify study population among the 4 412 60 -70 years old permanent residents in Renqiu region.Face to face health questionnaire,physical examination,laboratory tests were used.According to the gender group,the correlation between neck circumference and obesity related indexes and metabolic disorders associated with insulin resistance were analyzed.Results Comparing neck circumference and waist circumference,waist height ratio, and body mass index(BMI) of man and woman respondents,the differences were statistically significant.Neck circum-ference and waist circumference,waist height ratio,and BMI had positive correlation(male:r =0.752,0.695 and 0.761.W:r =0.707,0.655,0.721,all P <0.01).Increased trends of neck circumference,waist circumference,waist height ratio and BMI coincided with increased trend of thypertension,diabetes,hyperlipidemia and hyperinsulinemia and hyperlipidemia,and no gender differences.With the increase of the neck circumference,the incidence of above mentioned diseases also increased accordingly.Conclusion Neck circumference was associated with obesity related indexes and metabolic disorders associated with insulin resistance.Neck circumference measurement can be used as an effective indicator of central obesity,and had great significance for early prediction and prevention of metabolic disorders associated with clinical insulin resistance.

Objective:To analyze the relationship between self-disclosure, self-efficacy and medical coping modes in adolescent depression, and explore the mediating effect of self-efficacy between self-disclosure and medical coping modes.Methods:Using the convenience sampling method, a total of 403 adolescents with depression in a tertiary psychiatric hospital in Beijing were recruited from March 2020 to March 2021. The data of general information questionnaire, distress disclosure index scale, medical coping modes questionnaire and general self-efficacy scale were collected.SPSS 26.0 software was used to analyze the correlation between self-disclosure, self-efficacy and medical coping modes of adolescent patients with depression, and Stata 13.1 software was used to analyze the mediating effect of self-efficacy between self-disclosure and medical coping modes.Results:The scores of dimension of the medical coping modes of adolescent depression patients were(16.90±3.84) for facing, (16.34±2.88) for yielding, (12.48±4.31) for avoiding, (30.47±9.91) for self-disclosure and (19.63±6.54) for self-efficacy, respectively. Self-disclosure and self-efficacy were positively correlated with facing of medical coping modes ( r=0.301, 0.327, both P<0.01), and negatively correlated with yielding of medical coping modes ( r=-0.465, -0.487, both P<0.01). Self-disclosure was negatively correlated with avoidance of medical coping modes ( r=-0.118, P=0.018). The direct effect of self-efficacy on medical coping modes was 0.103, and the total effect was 0.365, and the mediating effect accounted for 28.22%. Conclusion:Self-efficacy partially mediates between self-disclosure and medical coping modes in adolescents with depression.
