ABSTRACT
A lot of evidence have proved that low level of cardiopulmonary fitness (i.e.functional capacity ) is related to high risk of cardiovascular diseases (CVD) ,high all‐cause mortality and high mortality of cancer .Cardiopulmonary fitness low level combined traditional risk factors can improve risk prediction for CVD .The present article aimed at reviewing cur‐rent knowledge about correlation among CVD ,other diseases and cardiopulmonary fitness ,improving people＇s consciousness for impact of cardiopulmonary fitness on risk prediction in order to optimize prevention and treatment of diseases .
ABSTRACT
Objective To explore the chain mediating effect of mastery and self-efficacy between optimism and resilience of breast cancer patients.Methods Totally 262 breast cancer patients were investigated with general information questionnaire,resilience scale (RS-14),mastery scale for Chinese version (MSC),general self-efficacy scale (GSES) and revised life orientation test (LOT-R).Causual steps and Bootstrap method were used to test the chain mediating effect of mastery and self-efficacy between optimism and resilience.Results The media score of the participants was 18 for optimism,and the average score of the participants was 27.1±4.6 for mastery,26.0±5.9 for self-efficacy,76.6± 13.9 for resilience.There existed a significant difference in RS-14 scores among the patients with different family relationships,family income,and form of payment (all P＜0.05).Correlation analysis showed that optimism,mastery,self-efficacy,and resilience were positively correlated with each other(r=0.57-0.74,all P＜ 0.01).Mediation modeling analysis showed that optimism had a direct effect on resilience.The effect value was 0.361,and the effect was 49.7％.Mastery and self-efficacy mediation effect value were 0.123 and 0.162,and the mediation effect were 16.9％ and 22.3％.While chain mediating effect of mastery-self-effcacy was also significant,and the mediation effect value was 0.081 and the mediation effect was 11.1％.Conclusion Optimism influences breast cancer patients' resilience,not only through the direct path,but also through the indirect path of mastery and self-efficacy,as well as the chain mediating path between these two variables.
ABSTRACT
Objective:To systematically review the resilience intervention in patients with cancer, so as to evaluate its effectiveness. Methods: Studies published until March 2017 were searched in CNKI, VIP, WanFang Data, CBM, PubMed, Cochrane library, Wiley Online Library, Elsevier ScienceDirect, Springer Link and EBSCO. The randomized controlled trials(RCTs) about resilience intervention in patients with cancer were included. Two reviewers independently performed screening, quality assessment and data extraction Qualitative synthesis was adopted to review the resilience intervention and to evaluate its effectiveness of included studies. Results: Totally 14 studies were included for the analysis. Eight studies evaluated the effectiveness of individuation intervention, and 6 studies evaluated the effectiveness of group intervention. Thirteen studies suggested that individuation intervention and group intervention might significantly improve the resilience in cancer patients. Conclusion: The results suggest individuation or group intervention may improve the resilience in patients with cancer. Current studies on resilience intervention are limited, and the measure has been taken seems lacks of high-quality research design.
ABSTRACT
Objective: To explore regulating effect of protosappanin A (PrA) on dendritic cell (DC) maturation.Methods: SPF male Wistar rats and SD rats were selected as subjects.During DC maturation induced by lipopolysaccharide (LPS), methyl thiazolyl tetrazolium (MTT) method was used to screen proper concentrations of PrA.Different concentrations of PrA were used to pretreat LPS-induced DC, difference of DC surface molecule CD80 and CD86 expressions were analyzed;DC's ability in activating T cell proliferation, expression levels of CD4, CD25 and Foxp3 on surface of regulatory T cells (Treg), and levels of interleukin (IL)-10 and IL-12 secreted by DC in supernatant were measured.Results: Compared with immature DC (imDC) group, there were significant rise in expressions of DC surface molecule CD80[(31.50±29.04)% vs.(63.80±14.03)%] and CD86[(36.10±27.21)% vs.(62.60±12.37)%] in LPS-DC group, P<0.01 both;compared with LPS-DC group, there were significant reductions in expressions of CD80[(63.80±14.03)% vs.(39.70±26.60)] and CD86[(62.60±12.37)% vs.((37.90±26.93)] in 20-DC group (DC cultured with 20nmol/L PrA), P<0.05 both.Compared with LPS-DC group, there were significant reductions in DC-activated T cell proliferation capacity [(0.39±0.06) vs.(0.32±0.46) vs.(0.28±0.08)] and IL-12 level [(250.00±89.81) pg/ml vs.(176.80±49.89) pg/ml vs.(134.30±60.64) pg/ml], and significant rise in expression of Treg [(0.42±0.23) vs.(0.76±0.20) vs.(0.93±0.52)] and IL-10 level [(145.80±70.28) pg/ml vs.(274.00±131.93) pg/ml vs.(354.00±146.22) pg/ml] in 5-DC group and 20-DC group (P<0.05 all for 5-DC group, P<0.01 all for 20-DC group).Conclusion: PrA can inhibit LPS-induced DC maturation, including reducing expressions of surface molecule CD80 and CD86, suppressing the capacity to activate allogeneic T lymphocyte proliferation, inducing Treg proliferation and affecting levels of relative cytokines.
ABSTRACT
Objective To explore the related pelvic floor anatomy to the pathological vaginal relaxation and key points of the vaginal tightening surgery.Methods The vaginal tightening surgery was performed in 24 cases of vaginal relaxation.The key points of this operation included levator ani muscle suturation and perineal body reconstruction,and anal sphincter reconstruction as in case of the muscle injury grade Ⅲ.Results The degree of levator ani muscle separation was positively correlated with that of vaginal relaxation in all the 24 cases.18 cases were followed up from 6 months to 2 years,and had no complications of rectovaginal fistula and infections.The average level of perineal body was increased from 2.3 cm to 3.5 cm.Vaginal length of 6 cm from vaginal orifice was proper with good tightness.The patients felt strong anal contraction,enhanced ability of vaginal tightening and improved quality of sex life.There were no more infections of genitourinary tract.Conclusions Through levator ani muscle suturation and perineal body reconstruction,it can get the vaginal tightening effect.
