目的 了解老年卧床患者营养状况及其相关因素，为临床治疗及健康宣教提供依据。 方法 采用简易营养评价精法（MNA-SF）简化量表调查2010年11月－2012年3月成都市住院老年卧床患者的营养状况，同时采用自行设计的问卷调查其相关因素。 结果 老年卧床患者82.4%营养不良，而且不同文化程度、年龄、性别及病情的患者营养状况不同，差异有统计学意义（P＜0.05），多因素分析发现，年龄、病情、卧床分级、抑郁是影响老年卧床患者营养的主要因素，病情重，年龄大、抑郁得分高、卧床分级高的老年卧床患者营养状况越差。 结论 老年卧床患者营养状况受多种因素影响，应根据患者不同情况进行营养相关知识宣教，改善患者的健康状况。
ObjectiveTo systematically review the association of body mass index (BMI) and mortality in chronic heart failure (CHF) pationts.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect cohort studies about the association of BMI and mortality in CHF patients from inception to June, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 20 cohort studies involving 91 572 CHF patients were included. The results of meta-analysis showed that, compared to patients with normal weight, underweight individuals were associated with higher mortality (HR=1.48, 95%CI 1.36 to 1.62, P<0.001), whereas overweight (HR=0.86, 95%CI 0.78 to 0.94, P=0.002) and obese (HR=0.78, 95%CI 0.68 to 0.90, P=0.001) patients were associated with lower mortality.ConclusionCurrent evidence shows that underweight is associated with a higher risk of all-cause mortality among patients with CHF, whereas overweight and obese are associated with lower risk of all-cause mortality. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
ObjectivesTo systematically review the efficacy and safety of esomeprazole versus omeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding (ANVUGIB).MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect the randomized controlled trials (RCTs) about the efficacy and safety of esomeprazole versus omeprazole in the treatment of ANVUGIB from inception to January, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 17 RCTs involving 2 086 patients were included. The results of meta-analysis showed that, the total effective rate of esomeprazole group was higher than omeprazole group (RR=1.09, 95%CI 1.04 to 1.14, P=0.000 6), the incidence of adverse reactions was lower than omeprazole group (OR=0.27, 95%CI 0.18 to 0.40, P<0.000 01), the average hemostasis time was shorter than omeprazole group (MD=−0.64, 95%CI −0.94 to −0.34, P<0.0001), and the difference were statistically significant.ConclusionsCurrent evidence shows that in the treatment of ANVUGIB, esomeprazole has rapid hemostasis, significant effect and fewer adverse reactions, which is worthy of wide application and promotion. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
Objective To study the expression of NLRP3 inflammasome and its downstream inflammatory factors in patients with chronic obstructive pulmonary disease (COPD) and healthy controls, and to reveal the effect and significance of NLRP3 inflammasome in the pathogenesis of COPD. Methods Forty patients with acute exacerbation COPD (AECOPD) who were hospitalized from November 2016 to May 2017 were recruited in the AECOPD group, and recruited in the stable COPD group when they entered the stable stage. Forty healthy individuals were recruited in the control group. General information and peripheral blood were collected from each subject. The levels of NLRP3 mRNA and caspase-1 mRNA in peripheral blood mononuclear cells were measured by real-time PCR. The levels of IL-18 and IL-1β were measured by enzyme-linked immunosorbent assay. Results The levels of NLRP3 mRNA, IL-18 and IL-1β in the AECOPD patients were significantly higher than those in the stable COPD group [2.11±0.77, 12.79 (7.10, 43.13) pg/ml, 17.02 (8.36, 52.21) pg/ml vs. 1.60±0.44, 10.66 (6.32, 18.59) pg/ml, 13.34 (7.07, 16.89) pg/ml, all P<0.05] . The levels of NLRP3 mRNA, IL-18 and IL-1β in the AECOPD patients were significantly higher than those in the control group [2.11±0.77, 12.79 (7.10, 43.13) pg/ml, 17.02 (8.36, 52.21) pg/mlvs. 1.00±0.49, 6.29 (4.73, 7.93) pg/ml, 5.93 (4.81, 9.67) pg/ml, all P<0.05]. The levels of NLRP3 mRNA, IL-18 and IL-1β were significantly higher in the stable COPD group than the control group [1.60±0.44, 10.66 (6.32, 18.59) pg/ml, 13.34 (7.07, 16.89) pg/mlvs. (1.00±0.49, 6.29 (4.73, 7.93) pg/ml, 5.93 (4.81, 9.67) pg/ml, all P<0.05]. Correlation analysis showed that the plasma IL-18 level was positive correlated with leukocyte count and neutrophil percentage in the AECOPD group (r=0.372, P<0.05;r=0.386, P<0.05). The expression of NLRP3 mRNA in the AECOPD group and stable COPD group were positively correlated with the CAT score (r=0.387, P<0.05;r=0.399, P<0.05) . Conclusion NLRP3 inflammasome is involved in the inflammatory response in COPD patients.
ObjectivesTo systematically review the association between body mass index (BMI) and mortality of chronic obstructive pulmonary disease (COPD).MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect cohort studies on the association between BMI and mortality of COPD from inception to February, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 14 cohort studies involving 494 060 COPD patients were included. The results of meta-analysis showed that, compared with patients having a normal weight, underweight individuals were associated with higher mortality (RR=1.40, 95%CI 1.15 to 1.71, P=0.000 8), whereas overweight (RR=0.65, 95%CI 0.54 to 0.79, P<0.000 1) and obese (RR=0.37, 95%CI 0.20 to 0.67, P=0.001) patients were associated with lower mortality.ConclusionsCurrent evidence shows that underweight is associated with a higher risk of all-cause mortality among patients with COPD, whereas overweight and obese are associated with lower risk of all-cause mortality in these patients. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
