Objective To search,evaluate and summarise the best evidence on non-drug intervention for nipple pain or injury in breastfeeding mothers.Methods Based on the"6S pyramid"evidence model,desktop searches were conducted on databases of UpToDate,Joanna Briggs Institute evidence-based practice database(JBI),National Guideline Clearinghouse(NGC),National Institute for health and Care Excellence(NICE),Guidelines International Network(GIN),Registered Nurses'Association of Ontario(RNAO),American College of Obstetricians and Gynecologists(ACOG),Medlive,Chinese Medical Association(CMA)website,Breastfeeding Medical Association(BMA),CNKI,Wanfang Data,SinoMed,Cochrance Library,PubMed,Embase,Web of Science,and CINAHL for literature in non-drug interventions for nipple pain or injury in breastfeeding women.The literature included clinical guidelines,decisions,recommended practices,evidence summaries,expert consensus,systematic reviews and randomized controlled trials(RCTs).The searched databases spanned from 1st January,2013 to 30th April,2024.Two researchers who were trained in evidence-based nursing independently evaluated the methodological quality,extracted and integrated evidence from eligible literature.Results A total of 15 documents were included,consisting of 5 clinical guidelines,2 clinical decisions,1 expert consensus,6 systematic evaluations and 1 RCT.Thirty-one pieces of evidence were summarised across 4 categories:accurate perinatal assessment,feeding guidance,non-drug intervention and health education.Conclusion The summarised best evidence on non-drug intervention for nipple pain or injury in breastfeeding women provides an evidence-based basis for clinical healthcare professionals.

This paper provides a review on the concept, current status, assessment tools, influencing factors, and intervention strategies regarding the compliance of lymphedema prevention behaviors in postoperative breast cancer patients. The aim is to improve the compliance of lymphedema prevention behaviors in these patients, reduce the incidence of lymphedema, and provide a reference for future clinical intervention studies in this field.

Objective:To retrieve the evidence on rehabilitation functional exercise for total knee arthroplasty (TKA) patients both domestically and internationally, and summarize the best evidence to provide a basis for constructing a management plan of rehabilitation functional exercise for TKA patients.Methods:Using population, intervention, professional, outcome, setting and type of evidence (PIPOST) to construct evidence-based nursing issues, all evidence on rehabilitation functional exercise for TKA patients was searched through computers in the Joanna Briggs Institute (JBI) Evidence-Based Health Care Center in Australia, British Medical Journal (BMJ) Best Practice, Embase, UpToDate, Web of Science, Cochrane Library, PubMed, American College of Sports Medicine, National Institute for Health and Clinical Excellence, China National Knowledge Infrastructure, WanFang Data and China Biomedical Literature Database. The Chinese and English search terms were "knee replacement/knee arthroplasty" and "functional training/exercise/strength training/early mobilization/recovery/ rehabilitation". The types of literature included guidelines, systematic reviews, summary of evidence, expert consensus, clinical decision-making, and randomized controlled trials (RCTs) . The search period was from the establishment of the database to January 10, 2023. Two researchers trained in evidence-based nursing independently completed the literature quality evaluation, and combined with professional judgment, extracted and summarized evidence for literature that met quality standards.Results:A total of 11 articles were included, including 4 guidelines, 4 systematic reviews, 2 RCTs, and 1 clinical decision-making. A total of 26 best evidence pieces were summarized from 5 aspects, namely multidisciplinary organizational management, pre-rehabilitation exercise, rehabilitation functional exercise plan, continuous function exercise, and exercise compliance.Conclusions:The best evidence summarized regarding rehabilitation functional exercise for TKA patients can provide a basis for medical and nursing staff to develop management plans. Medical and nursing staff need to consider clinical practice, patient's own condition, and willingness when applying evidence, and develop targeted rehabilitation functional exercise plans.

Objective To study the molecular mechanism of injection with hepatocyte growth factor (HGF) at different doses on angiogenesis in myocardium of dogs with acute myocardial infarction (MI).Methods Sixteen 1.5-year-old male hybrid dogs,weighing 11-13 kg,were divided into 500 ?g HGF treatment group,1 000 ?g HGF treatment group,sham operation group,and no MI interference group,4 dogs in each group.Expressions of VEGF,HGF,CD31,and platelet factor Ⅷ in myocardium of dogs with MI were detected,the number of micro blood vessels was calculated,and correlation between angiogenesis and expression of HGF and VEGF was analyzed in 28 d after the model was established.Results HGF gene therapy could up-regulate the expression of CD31 and VEGF.The expression of CD31 and VEGF mRNA was 0.82 and 0.39 respectively in 1 000 ?g HGF group,and 0.47 and 0.21 respectively in 500 ?g HGF group.The expression of VEGF mRNA was 0.09 and no expression of CD31 mRNA was found in MI group.HGF could increase the angiogenesis in infracted myocardium.The microvascular density was 126.4?10.6,79.8?6.0,and 21.7?2.5/mm2,respectively,in 1 000 ?g HGF group,500 ?g HGF group,and MI group (P

Objective To detect the spores of sulfite-reducing anaerobes in water. Methods At first the assay on form of the spores was accomplished, then reducing incubation was used to observe the change of the medium color. It indicated that sodium sulfite was reduced if the color of the medium became to black and positive result was able to be determined. Results 54 specimens including pure water, mineral water, secondary drinking water, source water for drinking, swimming pool water and cooling water of air conditioner were assayed. Sulfite-reducing anaerobes were found in 5 specimens of 7 source water samples and the other specimens showed negative results. The detection rate was 9.2%. Conclusion The determination of the spores of sulfite-reducing anaerobes in water was helpful to predict the contaminative degree and situation of water resource, and provide the scientific basis for prevention and control of water pollution.

Objective To study a rapid and sensitive method for determination of virulence-associated genes in O1El Tor,O139,non-O1/non-O139Vibrio cholerae strains.Methods Five pairs of primers were designed respectively ac-cording to cholera toxin sub-unit A gene(ctxA),accessory cholera enterotoxin gene(ace),zonula occludens toxin gene(zot),toxin coregulated pilus A gene(tcpA)and toxR regulatory protein gene(toxR).Multiplex PCR(MPCR)procedures for simultaneously detecting those five genes were established.The gene information of the virulence-associated genes in the Vibrio cholerae strains was obtained through agar gel electrophoresis for products of single amplification of the MPCR.Results The five virulence-associated genes in the positive control Vibrio cholerae O139(MO45strain)could be detected and the results were correct,which could meet the designed request for the method.In the other tested strains(O1EL Tor,O139,non-O1/non-O139)could be detected1to5kinds of the virulence-associated genes.Based on the results of the variety of carried virulence-associated genes,the tested Vibrio cholerae strains could be classified as5kinds of genetypes,and the Vibrio cholerae could be distinguished between toxic and non-toxic strains.The sensitivity of the MPCR approach reached to10 2 cfu/ml.Conclusion This method is rapid,specific and sensitive,which possess great value for practical application.
