Objective To retrieve,assess and summarize the best evidence on breast milk expression of premature infants' mothers in maternal separation so as to provide high-quality evidence for medical staff to carry out breast feeding guide. Methods Guidelines,systematic reviews,recommended practices and evidence summaries were retrieved in the UpToDate,WHO,Academy of Breastfeeding Medicine(ABM), Cochrane Library,Joanna Briggs Institute Library,Registered Nurses' Association of Ontario(RNAO), National Guideline Clearinghouse(NGC),PubMed,Embase,Chinese Biological Medicine,Chinese National Knowledge Infrastructure,WanFang data,VIP and the evidence-based nursing database of Fudan University from January 2008 to December 2018. Results A total of 7 literatures were included,two guidelines,one clinical decision,two systematic reviews and two evidence summaries. A total of 19 evidences were gathered in 7 aspects,such as training for medical staff,parents' education,selection of breast pump,preparation before expression,operational skills of breast expression,measures for increasing lactation and expression effects monitor. Conclusions Clinical medical staff should lay down the individualized nursing measures for maternal women to ensure breast milk collected as soon as possible,gain enough breast milk and fill the bill of growth and development of premature infants.

Objective:To investigate the efficacy and safety of prednisone combined with standard quadruple antituberculosis therapy (HRZE) in the treatment of tuberculous pleurisy.Methods:A prospective study was conducted involving 120 patients with tuberculous pleurisy who were admitted to the Shaanxi Provincial Tuberculosis Prevention and Control Hospital from February 2021 to February 2023. The patients were randomly assigned to a study group and a control group, with 60 patients in each group, using a computer-generated randomization method. The control group received HRZE alone, while the study group received prednisone therapy and HRZE. The efficacy, clinical indicators, adverse reactions, and serum inflammatory factor levels were compared between the two groups.Results:The total response rate in the study group was significantly higher than that in the control group [93.33% (56/60) vs. 78.33% (47/60), χ2 = 5.55, P < 0.05). In the study group, the time for clinical symptom improvement was (10.34 ± 1.65) days, the time for pleural effusion absorption was (21.37 ± 4.16) days, the pleural thickness measured (2.15 ± 0.35) mm, and the duration of hospitalization was (23.19 ± 4.56) days. They were significantly shorter or smaller than those in the control group [(13.27 ± 2.30) days, (27.25 ± 4.95) days, (2.62 ± 0.40) mm, (28.42 ± 5.60) days, t = 8.02, 7.04, 6.85, 5.61, all P < 0.05]. There was no significant difference in the incidence of adverse reactions between the two groups (χ2 = 2.91, P > 0.05). After 8 weeks of treatment, all serum inflammatory factors improved in both groups compared with baseline levels. In the study group, levels of interleukin-6 [(90.37 ± 12.05) ng/L] and interleukin-18 [(270.94 ± 14.58) ng/L] were significantly lower than those in the control group [(110.59 ± 16.90) ng/L, (296.10 ± 25.29) ng/L, t = 7.55, 6.68, both P < 0.05]. Levels of interleukin-10 [(78.91 ± 8.25) ng/L] and soluble interleukin-2 receptor [(1875.82 ± 359.23) pg/L] in the study group were significantly higher than those in the control group [(70.40 ± 7.16) ng/L, (1566.87 ± 311.02) pg/L, t = -6.03, -5.04, both P < 0.05]. Conclusion:The combination of prednisone and HRZE demonstrates good efficacy and safety, and it is beneficial for improving inflammatory factors.

Objective To detect the serum levels of CC chemokine receptor 2(CCR2)and C-reactive pro-tein(CRP)in stroke patients,and analyze their relationship with the severity of stroke associated pneumonia and their clinical significance.Methods A total of 78 patients with stroke associated pneumonia who were di-agnosed and treated in the hospital from October 2022 to February 2023 were collected as the study group,ac-cording to the severity of pneumonia,the study group was divided into mild group(31 cases),moderate group(29 cases),and severe group(18 cases),78 stroke patients who did not develop pneumonia were included into control group.Pearson method was applied to analyze the correlation between serum CCR2 and CRP levels in stroke associated pneumonia patients.Multivariate Logistic regression was applied to analyze the factors influ-encing the occurrence of stroke associated pneumonia.Receiver operating characteristic(ROC)curve was ap-plied to analyze the diagnostic value of serum CCR2 and CRP for stroke associated pneumonia.Results The National Institute of Health stroke scale(NIHSS)score,serum CCR2,and CRP levels in the study group were obviously higher than those in the control group(P<0.05).The levels of serum CCR2 and CRP increased with the aggravation of pneumonia(P<0.05).The levels of serum CCR2 and CRP in the study group were positively correlated(r=0.799,P<0.05).NIHSS score,CCR2,and CRP levels were risk factors for stroke associated pneumonia in stroke patients(P<0.05).The area under the curve(AUC)for the diagnosis of stroke associated pneumonia using serum CCR2 and CRP alone was 0.873 and 0.888,respectively,and the AUC for the combined detection of the two was 0.936,the combined detection of the two was superior to the individual detection of serum CCR2 and CRP(Zcombination-CCR2=1.987,Zcombination-CRP=1.832,P=0.041,0.047).Conclusion Serum CCR2 and CRP are closely related to the severity of stroke associated pneumonia,and their combined detection has high diagnostic value for stroke associated pneumonia.

Objective To investigate the diagnostic value of serum soluble fms-like tyrosine kinase 1(sFlt-1)and soluble differentiation cluster 14(sCD14)in stroke-associated pneumonia(SAP).Methods A total of 67 SAP patients admitted to the hospital from March 2022 to January 2023 were selected as the study group,and 50 stroke patients without pneumonia during the same period were selected as the control group.Enzyme-linked immunosorbent assay was used to measure serum sFlt-1 and sCD14 levels.Pearson correlation analysis was used to analyze the correlation between serum sFlt-1,sCD14 levels and clinical data.Multivariate Logistic regression was used to analyze the influencing factors of SAP in patients with stroke.Receiver operating char-acteristic(ROC)curve was used to analyze the diagnostic value of serum sFlt-1 and sCD14 levels in predicting SAP in patients with stroke.Results The serum levels of sFlt-1 and sCD14 in SAP patients were higher than those in stroke patients without pneumonia and stroke patients with pneumonia alone(P＜0.05).SAP in stroke patients was associated with age,atrial fibrillation,heart failure,aspiration,dysphagia,brain stem stroke,proton pump inhibitor use,fever,cough,dyspnea,low-density lipoprotein cholesterol,procalcitonin(PCT),C-reactive protein,white blood cell count,national institutes of health stroke scale(NIHSS)score,clinical pulmonary infection(CPIS)score(P＜0.05).Correlation analysis showed that serum sFlt-1 level was positively correlated with sCD14(r=0.439,P＜0.001),and serum sFlt-1 and sCD14 levels were positively correlated with NIHSS score and CPIS score(P＜0.05).Multivariate Logistic regression analysis showed that sFlt-1,sCD14,proton pump inhibitor use,PCT,dysphagia,and age were the influencing factors of SAP in stroke patients(P＜0.05).ROC curve results showed that the area under the curve of serum sFlt-1 and sCD14 combined to evaluate SAP in stroke patients was higher than that of single detection(ZsFlt-1-combined=2.194,P=0.028,ZscD14-combined=2.310,P=0.002).Conclusion The serum levels of sFlt-1 and sCD14 are in-creased in SAP patients,and the combination of the two has a good diagnostic value for predicting the occur-rence of SAP.
