RÉSUMÉ
We applied literature review and the Delphi method to develop technical operation of manual lactation technique. The databases and websites were systematically searched, such as UpToDate, the Cochrane Library, CNKI, VIP, Wanfang, and SinoMed. The evidence related to the technique was evaluated by Appraisal of Guidelines for Research and Evaluation (AGREE Ⅱ), and A Measure Tool to Assess Systematic Reviews 2 (AMSTAR 2). the included evidence was classified and summarized to form the preliminary draft of the technical operation specification. A total of 26 experts were selected to evaluate the draft, and some recommendations were deleted and modified according to the screening criteria and expert opinions, resulting in the final technical specifications for manual lactation technique applicable to health care professionals. The study included 4 guidelines, 5 expert consensus articles, 2 clinical decisions, and 3 systematic reviews, and the overall quality of the evidence was fair. A total of 26 questionnaires were collected in each of 2 rounds of expert consultation, with a 100% return rate and an overall authority coefficient of 0.91. The technical practice specification was formed in 11 aspects, including assessment content, indications, contraindications, operation methods, adverse events, and treatment methods, with a total of 50 recommendations. The technical operation specification is comprehensive, and the recommendations are clearly expressed, which is in line with the real clinical situation and can provide effective reference for the clinical practice of this technique.
RÉSUMÉ
Objective:To retrieve, evaluate, integrate the evidence of Traditional Chinese Medicine (TCM) nursing appropriate technology for chemotherapy-induced nausea and vomiting at home and abroad, and summarized the relevant best evidence to provide evidence-based basis practice for the clinical standard management of chemotherapy-induced nausea and vomiting and improved the treatment efficiency of patients' symptoms.Methods:The study evidence on TCM nursing appropriate technology for chemotherapy-induced nausea and vomiting systemically retrieved in the websites and databases,included13 guidelines and evidence summary websites, namely National Guideline Clearinghouse, New Zealand Guidelines Group, Medlive, etc; 6 Oncology Professional Association Websites, namely British Columbia Cancer Agency, Cancer Care Ontario, National Comprehensive Cancer Network, Oncology Nursing Society, European Society for Medical Oncology, American Society of Clinical Oncology;11 electronic databases, namely CNKI, VIP, WanFang, CBM, PubMed, Web of Science, Embase, etc; supplementary searched expert consensus and practice guidelines for cancer diagnosis and treatment including evidence-based decision-making, guidelines, evidence summaries, best/recommended practices, systematic reviews, expert consensus, and government documents. The literature retrieval period was from the database construction to January, 2023. The guidelines individually evaluated by 3 researchers, and the remaining literature independently evaluated by 2 researchers. The literature that met the criteria extracted and graded. Finally, the expert group integrated the evidence and summarized the evidence topics.Results:A total of 12 articles were involved, included 2guidelines,2 evidence summaries,3 expert consensuses, and 5 systematic reviews. Finally,4 evidence topics and 20 pieces of best evidence were formed, included applicable population, efficacy, safety and intervention measure .Conclusions:The best evidence of TCM nursing appropriate technology treatment of chemotherapy-induced nausea and vomiting provided evidence resources for clinical transformation, for traditional Chinese medicine and integrated Chinese and western medicine nursing group to provide clinical decision-making basis, and according to the principle of syndrome differentiation to form personalized practice scheme, effectively improved patients' symptoms, promote the recovery of patients.
RÉSUMÉ
Objective The aim of this study is to explore the hypoglycemic effect of active components of Anoectochilus roxburghii on zebrafish models. Methods Anoectochilus roxburghii components were extracted and separated into three groups: the alcohol extraction group, macromolecular polysaccharide group (≥ 5 ×103) and small molecular polysaccharide group (＜5×103). Zebrafish embryos were exposed to 2% glucose solution (2% Glu) at 24 h to imitate acute hyperglycemia phenotype, and then treated with the three Anoectochilus roxburghii components. Based on this high-glucose model, the zebrafish embryos at 72 h were collected to detect the whole tissue glucose value. Furthermore, semi-quantitative PCR and whole mount in situ hybridization were performed to detect the expression of mRNA levels of glycometabolism-related genes. Results An acute diabetic zebrafish model was induced by high glucose stress. In this model, some key factors during glycometabolism such as insulin, pck-1 and pdx-1 were significantly affected, while the alcohol extracts of Anoectochilus roxburghii obviously reversed these abnormalities induced by high glucose stress, even to normal levels. Conclusions The alcohol extracts of Anoectochilus roxburghii has obvious hypoglycemic effect on diabetic zebrafish model. Our result suggest that Anoectochilus roxburghii has a potential application in the hypoglycemic drug screening.

Objective The aim of this study was to explore the inhibitory effect of alcohol extracts of Narcissus bulb on melanogenesis in zebrafish embryos.Methods Zebrafish embryos were exposed to different concentrations of alcohol extracts of Narcissus (0, 50, 100, 200, and 500 μg/mL), and then the formation of melanin was observed.Furthermore, we measured the enzyme activity of tyrosinase (TYR), which plays a pivotal role in melanogenesis.Meanwhile, the spatial and temporal pattern of melanin-specific marker genes were detected.Arbutin (Ar) was used as a positive control in all these experiments.Results The treatment of alcohol extracts of Narcissus bulb inhibited melanogenesis in the zebrafish embryos in a dose-dependent manner.Furthermore, the mRNA expression levels of melanin-related genes such as tyrosinase (TYR), silver (SILV) and Mitfa were significantly reduced after treatment with different concentrations of Narcissus extracts by in-situ and semi-quantitative PCR.Finally, the enzyme activity of tyrosinase was also gradually decreased with increasing concentrations of the alcohol extracts.Conclusions Narcissus alcohol extracts can effectively inhibit the production of melanin in zebrafish embryos.This study provides potential evidence and approaches for the screening of natural whitening compounds using zebrafish models.
