Objective:To retrieve and summarize evidence for prevention of hypothermia at birth in newborn.Methods:Databases such as Up To Date, BMJ Best Practice, National Institute for Health and Care Excellence(NICE), Joanna Briggs Institute (JBI), Cochrane Library, Registered Nurses′Association of Ontario (RNAO), American Heart Association(AHA), Web of Science, PubMed, Chinese Biology Medical Literature database, Wanfang Med Online were searched to collect relevant evidence for prevention of hypothermia at birth in newborn, including guidelines, systematic reviews, evidence summaries and expert consensus. Two researchers independently evaluated the quality of the literature and extracted the data of the literature which met the criteria.Results:Six articles were selected, including 1 clinical decision support system, 2 guidelines, 1 systematic review and 2 expert consensuses. Nineteen pieces of best evidence were summarized.Conclusions:This study summarized the best evidence for the prevention of hypothermia at birth in newborn, and provided evidence-based support for clinical practice.

Objective To investigate the correlation and clinical significance between the serum 25-hydrovitamin D3[25-(OH)D3] level and bronchiolitis in children. Methods Sixty-one children with bronchiolitis diagnosed by Xiamen Children′s Hospital between September 2016 and June 2017 were enrolled in the study. Forty-one healthy children were used as the healthy control group. All the children were tested by enzyme-linked immunosorbent assay for serum 25-(OH)D3levels and serum IgE,IgG,IgA and IgM content. The clinical data of children with bronchiolitis group were recorded in the meanwhile. Results (1) Com-paredwiththehealthycontrolgroup,theserumlevelsof25-(OH)D3[(59.47±23.66)nmol/Lvs.(69.94± 25.19)nmol/L],IgM[(1.27±0.49)g/Lvs.(1.56±0.43)g/L]andIgA[(1.38±0.83)g/Lvs.(1.71± 0. 61)g/L] were significantly lower in children with bronchiolitis;while the serum IgE[(106. 59 ± 67. 74) IU/L vs. (75. 95 ± 35. 27)IU/L] was significantly higher(P<0. 05). (2)The serum levels of IgE,IgG and IgA in children diagnosed bronchiolitis with vitamin D deficiency [( 177. 37 ± 82. 72 ) IU/L, ( 5. 46 ± 1. 95)g/L and(0. 68 ± 0. 24) g/L] were obviously different from those of children diagnosed bronchiolitis with vitamin D inadequate[(94.21 ±44.21)IU/L,(7.14 ±2.82)g/L and(1.35 ±0.72)g/L] and vitamin D normal group[(79. 60 ± 44. 30)IU/L,(8. 03 ± 2. 49)g/L and(1. 57 ± 0. 78)g/L](P<0. 05). There was no significant difference about serum levels of IgE,IgG,IgA and IgM between vitamin D inadequate and vita- min D normal group(P>0. 05). (3)The wheeze time was higher in bronchiolitis children with vitamin D deficiency[(3. 97 ± 1. 01) d] than those of patients with vitamin D inadequate[(2. 41 ± 0. 79) d] and vitamin D normal group[(2. 27 ± 0. 88)d](P<0. 05). The level of venous glucocorticoid utilization was higher in bronchiolitis children with vitamin D deficiency than that of patients with vitamin D normal group (58. 82% vs. 29. 03%)(P<0. 05). There was no significant difference about clinical data between vitamin D inadequate and vitamin D normal group(P>0. 05). Conclusion The serum 25-(OH)D3levels are lower in children with bronchiolitis than those in healthy children. The lower the level of vitamin D,the more severe the children with bronchiolitis. Vitamin D deficiency is an important cause of bronchiolitis in children,which may be related to immune dysfunction effected by vitamin D deficiency.

Objective:To evaluate the potential effects of serum lipid levels, appendicular skeletal muscle mass index (ASMI) and body mass index (BMI), together with its dynamic changes, on tumor progression in renal clear cell carcinoma patients, so as to inform body weight management.Methods:This prospective cohort study included a total of 100 patients with high-risk clear cell renal cell carcinoma. Serum lipid levels were detected, ASMI and BMI were measured using bioelectrical impedance analysis and the dynamic changes of BMI were tracked. The effects of BMI, ASMI and serum lipid levels on tumor progression within 2 years were explored.Results:Patients with normal BMI and low ASMI had 5.248 (95% CI: 1.946 to 14.153, P = 0.001) times higher risk of tumor progression than those who were overweight or obese. For every 0.1-unit increase in pre-operative HDL-C, the risk of tumor progression decreased by 0.771 (95% CI: 0.631 to 0.942, P = 0.011) times. Patients who experienced more than 5% decrease in BMI compared with baseline had 5.165 (95% CI: 1.735 to 15.370, P = 0.003) times the progression risk of patients whose BMI changed within ±5% from baseline. Conclusions:The advantage of obese clear cell carcinoma patients over normal-weight patients in tumor progression-free survival may be influenced by ASMI, pre-onset involuntary weight loss and lipid levels. Therefore, patient weight management should not merely focus on absolute BMI but tailor to individual characteristics, including cancer stage, body composition and metabolic status.

Gastrointestinal mucositis is one of the most debilitating side effects of the chemotherapeutic agent irinotecan (CPT-11). Andrographolide, a natural bicyclic diterpenoid lactone, has been reported to possess anti-colitis activity. In this study, andrographolide treatment was found to significantly relieve CPT-11-induced colitis in tumor-bearing mice without decreasing the tumor suppression effect of CPT-11. CPT-11 causes DNA damage and the release of double-stranded DNA (dsDNA) from the intestine, leading to cyclic-GMP-AMP synthase (cGAS)‒stimulator of interferon genes (STING)-mediated colitis, which was significantly decreased by andrographolide both in vivo and in vitro. Mechanistic studies revealed that andrographolide could promote homologous recombination (HR) repair and downregulate dsDNA‒cGAS‒STING signaling and contribute to the improvement of CPT-11-induced gastrointestinal mucositis. These results suggest that andrographolide may be a novel agent to relieve gastrointestinal mucositis caused by CPT-11.
