ABSTRACT
Objective@#To explore the association between light intensity physical activity (LPA) and sedentary behavior (SB) with body composition, so as to provide data references for improving adolescent physical health.@*Methods@#From August 2020 to January 2021, general information of 694 students in grade one of a high school in Foshan City was collected, and the 24 hour activity behavior and body composition of the students were measured objectively by triaxial accelerometer and bioelectrical impedance tester. Dual component multivariate regression and dual compositional isotemporal substitution model were used to explore the relationship between LPA and SB and body composition.@*Results@#LPA was associated with lower fat relative dominance (FRD) (male weekends FRD=-21.44%, female weekly FRD=-17.83%, weekdays FRD=-18.27%, P <0.05), and LPA was also associated with higher muscle relative dominance (MRD) and bone relative dominance (BRD) (male weekends MRD=12.78%, BRD= 12.87 %; female weekly MRD=11.64%, BRD=9.01%; female weekdays MRD=12.02%, BRD=9.23%, P <0.05). Replacing sedentary behavior (SB) with 10 minutes of LPA could reduce fat proportion [male:weekly -0.15(-0.26--0.04), weekdays -0.12 (-0.22--0.02); female:weekly -0.18(-0.27--0.08), weekdays -0.16(-0.25--0.07)) and increase muscle proportion (male:weekly 0.14(0.03-0.24), weekdays 0.11(0.02-0.21); female:weekly 0.17(0.07-0.26), weekdays 0.15(0.07-0.24)].@*Conclusion@#Interrupting continuous SB with LPA can serve as an intervention measure to promote physical health and fitness in adolescents. School should encourage students to engage in frequent LPA during breaks and after school activities, while avoiding prolonged SB.
ABSTRACT
Objective:To investigate the acceptance of advance care planning and its influencing factors in heart failure patients.Methods:A total of 208 patients with heart failure were surveyed by general data questionnaires and advance care planning acceptance questionnaires.Results:The total score of advance care planning acceptance of heart failure patients was (44.26 ± 11.73), the score of feeling dimension was (13.67 ± 5.72), the score of attitude dimension was (30.59 ± 6.33). 53.4%(111/208) of patients were willing to accept the talking about advance care planning. Regression analysis results showed that education level, New York Heart Association (NYHA) classification, communication status with medical staff and whether they had received life-sustaining treatment were important factors influencing of the acceptance of advance care planning in patients with heart failure.Conclusion:Patients with heart failure had higher acceptance of advance care planning. In clinical work, it is necessary to strengthen the scientific popularization of advance care planning in patients with low education level, low NYHA grade and no exposure to life-sustaining treatment. And strengthen the daily communication with patients to prepare for the follow-up advance care planning related communication.
ABSTRACT
Objective@#To quantify the serum levels of apoptosis-related molecules M30 and M65 in the patients with primary biliary cholangitis (PBC) and analyze their clinical significance for PBC. @*Methods@#A total of 79 patients with PBC and 40 healthy individuals were involved in this study from January 2017 to April 2019. The levels of serum M30 and M65 were measured by enzyme-linked immunosorbent assay (ELISA) and the ratio of M30/M65 was calculated. The parameters of liver function were tested by automatic biochemical analyzer. ALT, AST and GGT were determined by rate method, ALP was assayed by the method of NPP substrate-AMP buffer and T-Bil was determined by oxidation method. Autoantibodies including AMA-M2, anti-GP210 and anti-SP100 were detected by automated multiplexed bead-based and immunoblotting assays. The correlation of M30, M65 and M30/M65 ratio with liver function items were analyzed by spearman assay. The levels of M30, M65 and M30/M65 ratio were analyzed by ROC curve to evaluate their values in PBC screening. @*Results@#M65 level in PBC group was significantly higher than that in control group (P＜0.001) with statistically significant difference and M30/M65 ratio was significantly lower than that in control group with statistically significant difference (P＜0.001). There was no significant difference for the level of M30 between the two groups (P=0.641). Among the PBC patients, 18 were anti-GP210-positive and 17 were anti-SP100-positive. In anti-GP210 positive group the levels of M30 and M65 were significantly higher than those in the negative group (P values were 0.002 and 0.001 respectively). In anti-SP100 positive group the level of M65 was significantly higher than that in the negative group (P=0.027) and M30/M65 ratio was significantly lower than that in negative group with statistically significant difference (P=0.005). Spearman correlation analysis showed that the levels of M30 and M65 were positively correlated with ALT, AST and T-Bil (P＜0.05). The cut off values of M30 and M65 were 63.62 U/L and 155.37 U/L and M30/M65 was 0.32, respectively. The screening sensitivities were 63.30%, 89.10% and 93.30%, and the specificities were 51.60%, 90.00% and 75.00%, respectively. @*Conclusion@#The level of M65 in the serum of PBC patients significantly increased and M30/M65 ratio significantly decreased, which could be used as a promising serum marker of laboratory for PBC screening.
ABSTRACT
Objective:To explore the predictive value of serum thyroglobulin autoantibody (TgAb) for recurrence / metastasisin of thyroglobulin (TG)-negative and TgAb-positive patients with differentiated thyroid carcinoma(DTC) after thyroid ablation.Methods:The clinical data of 57 patients with DTC,undergoing complete resection of thyroid tissue,TG negative and TgAb positive,who were reviewed in Liaocheng People's Hospital during April 2013 to April 2015,were selected and divided into recurrence/metastasis group (n=20) and no recurrence/metastasis group (n=37).The TG and TgAb levels in the two groups were detected and compared by the electrochemical luminescence method,the sensitivity,specificity,positive predictive value and negative predictive value of TgAb in the diagnosis of DTC recurrence / metastasis were analyzed;the independent risk factors of DTC recurrence / metastasis were analyzed by Logistic regression.Results:The TgAb levels(72～3850 IU/mL) in the recurrence/metastasis group was higher than that(18～3638 IU/mL) in the no recurrence/metastasis group,the difference was statistically significant (P＜0.05).The sensitivity,specificity,positive predictive value,negative preictive value of TgAb in the diagnosis of recurrence/metastasis of DTC were 85.71％,83.33％,75.00％,90.91％,respectively.Logistic Regression analysis showed that the 100≤ TgAb ＜204 IU/mL,204≤ TgAb≤ 1000IU/mL,and ＞ 1000IU/rnL levels of TgAb were the independent risk factors of rucurrence/metastasis ofDTC (OR=1.267,2.853,6.791,P＜0.05).Conclusion:TgAb can be used as evaluation of an important index of the recurrence/metastasis of patients with DTC when serum thyroglobulin (TG) was negative and TgAb was positive after thyroid ablation.The higher the TgAb levels,the more probability of the recurrence/metastasis.

ABSTRACT
Objective To investigate the role of interleukin-27 (IL-27) in proliferation and differentiation of CD4+ T cells in ankylosing spondylitis(AS).Methods CD4+ T cells were separated from peripheral blood which collected from AS patients and health controls(HCs).Cells proliferation was detected by CCK-8 kit,and cytokines were analyzed by ELISA.Real-time PCR was used to determine the mRNA expression of T-bet and GATA3.Results Serum IL-27 level in patients with AS was obviously higher than that in HCs(P ＜0.01).The proliferation rate of CD4+ T cells and the level of IFN-γin cultured medium in AS were higher than those in HCs group after IL-27 stimulation (P ＜ 0.01).IL-27 could induce T-bet mRNA expression in CD4+ T cells in AS (t =14.3,P ＜ 0.01),but no change was found in GATA3 mRNA expression.Conclusions IL-27 could induce the proliferation of CD4+ T cells and the activation of T-bet pathway in AS.Furthermore,Th1 immune response and related cytokines could be induced by IL-27 in AS.These implicate that IL-27 may play an important role in AS related inflammation.
ABSTRACT
Objective To investigate the immune tolerance in animal models of primary biliary cirrhosis (PBC) by determining the cell proliferation and activation induced cell death (AICD).Methods C57BL/6 mice were injected with 5 mg/kg of polyI:C to develope PBC models. The lymphocytes and CD4~+ T cells were separated from spleens and livers 16 weeks later and were stimulated by M2, conA and anti-CD3 for cell proliferation and AICD. Expression of apoptosis related genes and proteins were detected by real time polymerase chain reaction (PCR) and Western blotting, respectively. Results ① The lymphocyte proliferation was 0.1988 ± 0.0111 in blank controls and 0. 2068±0. 0115 in PBS treated mice with no significant difference (P>0.05). However, an abundant lymphocyte proliferation was found in PBC mice (0. 358 ± 0. 022), which was higher than that in controls and PBS treated mice. The proliferation of lymphocyte from liver was greater than that from spleen in PBC mice (P<0.01). ② The apoptotic rate in blank controls (74.70%±4.58%) and PBS treated mice (74.20%±4.44%) was higher than that in PBC mice (44.85%±6.47%,P<0.01),but no difference was found between blank controls and PBS treated mice (P>0.05). Furthermore, the apoptosis rate of T cells from livers were significantly lower than that from spleens in PBC mice (P<0.01). ③ The expressions of FasL and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in PBC mice were lower than those in PBS treated mice (P<0. 01), but there was no change in expression of Fas was found. ④ The expression of Fas-associated death domain-like interleukin-1-β-converting enzyme-inhibitory protein (FLIP_L) in PBC mice was higher than that in blank controls. Moreover, the expression of FLIP_L in livers was higher than that in spleens in PBC mice (P<0. 01). Conclusios The elevated expression of FLIP_L may inhibit AICD. Besides, the decreased expressions of FasL and TRAIL may also help in the enhancement of the anti-apoptotic ability in lymphocytes and in the aggravation of portal area inflammation.

The paper describes the basis, scope, and contents of the index system for assessing maternity and child care institutions in Beijing. The new system, based on the readjustment, recombination and redistribution of the original index system for assessment, has two newly added elements, viz. financial position analysis and leadership style and organization culture. In order to make a distinction between leaders' responsibilities and an institution's orientations and to reduce behavior abnormality and information bias in the process of assessment, the new system has been divided into two major parts: evaluation of the institution's conditions for survival and capabilities for development, which is jointly decided by internal and external factors, and appraisal of the institution's performance, which is decided mainly by internal factors.
