Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

Objective:Gastric adenocarcinoma of the fundic gland type (GA-FG) is rare and often occurs in patients who are not infected with Helicobacter pylori. The current study analyzed and summarized the clinical, endoscopic, and pathological features of GA-FG, in an effort to improve its diagnosis. Methods:Patients who were diagnosed with GA-FG and treated with endoscopic submucosal dissection (ESD) resection at the Department of Gastroenterology, First Affiliated Hospital of Zhejiang Chinese Medical University from January 1st 2020 to October 1st 2022 were included in the study. Their clinical manifestations, endoscopic features, pathological immunohistochemistry, and other characteristics were analyzed.Results:A total of 14 patients with GA-FG were included in the study, 5 males and 9 females, with a mean age of 59 years. Most had no substantial clinical manifestations. Twelve patients were H. pylori-negative, all patients underwent ESD resection, and all patients survived during the follow-up period of 13±9 months. Eleven patients had postoperative endoscopic follow-up records, and no recurrence was detected. Fifteen lesions were detected (2 were present in 1 patient). Twelve were located in the upper 1/3 of the stomach, 10 were ≤ 1 cm in diameter, 12 had a morphology of type 0-Ⅱa, 8 had visible discoloration changes, and 12 had visible vasodilation on the surface. Magnified endoscopy and narrow-band imaging indicated that 12 of the lesions had enlarged marginal crypt epithelium, without any obvious microvascular pattern abnormalities and no obvious borderline. After resection the pathological specimens were all without vascular infiltration, and there was no atrophy of the mucosa at the edge of the lesion. In immunohistochemistry analyses MUC-2 was negative in all cases. MUC5AC was negative in 11 cases, MUC-6 was positive in all cases, and Ki-67 was ≤ 5% in 12 cases. Conclusions:GA-FG is a newly identified type of gastric cancer with low malignancy and a good prognosis. Characteristic discoloration and surface dilated vessels are often evident endoscopically. Enlarged marginal crypt epithelium and no visible boundary lines are often apparent in magnification endoscopy and narrow band imaging.

Due to the complexity of traditional Chinese medicine (TCM) interventions and the diversity of herbal components, single-omics technologies such as genomics, transcriptomics, proteomics, and metabolomics often cannot comprehensively elucidate the scientific connotations of TCM. Multi-omics technologies driven by system biology can analyze the theoretical connotations and application mechanisms of TCM from different levels such as genes, gene expression, proteins, and metabolites, in line with the holistic view of TCM, which helps to promote the modernization of TCM. By reviewing the literature on the application of omics technologies in the field of TCM, it is found that multi-omics technologies have been widely used in TCM for syndrome differentiation, evaluation of herbal quality, elucidation of pharmacological mechanisms, and drug toxicity assessment, providing comprehensive explanations of the mechanisms of action of TCM and overcoming the limitations of single-omics technologies, and having obtained significant achievements. However, multi-omics technologies also face challenges such as high cost, difficulties in data analysis due to large data volumes, and insufficient translation of research results. In the future, it is expected that through strengthening interdisciplinary cooperation, conducting long-term and dynamic clinical research, standardizing and normalizing data analysis processes, adopting appropriate and reasonable multi-omics integration patterns, establishing multi-omics databases for TCM, revealing the individualized characteristics, therapeutic mechanisms, and disease regulatory networks of TCM, the modernization of TCM will be promoted.

OBJECTIVE To establish characteristic chromatogram of Yao medicine Kadsura longipedunculata and the method for the content determination of its main component anwulignan, and evaluate the anti-inflammatory activity of anwulignan. METHODS HPLC method was performed with acetonitrile-0.5% phosphoric acid solution as the mobile phase for gradient elution. The characteristic chromatogram of K. longipedunculata was established and similarity was evaluated by Similarity Evaluation System for Chromatographic Fingerprint of TCM (2012 edition). The content of anwulignan in K. longipedunculata was determined. Lipopolysaccharide induced RAW264.7 macrophages were selected as inflammatory cell model to investigate the effects of anwulignan on the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6. RESULTS The similarities of characteristic chromatogram for 10 batches of K. longipedunculata ranged 0.901-0.994, and 9 common peaks were determined; 3 components were identified, such as changnan schisantherin E, kadsulactone A, anwulignan. The contents of anwulignan were (0.72±0.05)-(1.21±0.03) mg/g(n=3). Anwulignan of 0.125-0.5 μg/mL greatly decreased the levels of TNF-α, IL-1β and IL-6 in the supernatant of inflammatory model cells (P<0.05 or P<0.01). CONCLUSIONS HPLC characteristic chromatogram of K. longipedunculata and the method for the content determination of anwulignan are all established, and anwulignan may be the active ingredient of anti-inflammatory effect in K. longipedunculata.

Combining the knowledge of traditional Chinese medicine and modern medicine on glucolipid metabolism disorders, it is believed that the formation process of glycolipid metabolism disorders can be presented as five states "depression, phlegm-dampness, heat, blood stasis, and deficiency", and the turbid pathogens run through the whole process. Accordingly, the method of "regulating states and removing turbidity" is proposed, which is specifically the method of resolving depression and turbidity, dispelling phlegm-dampness and turbidity, clearing heat and turbidity, dispelling blood stasis and turbidity, and replenishing deficiency and removing turbidity. Combined with the biological basis of glycolipid metabolism disorder, through the analysis of the clinical application of each method and the related mechanism of action, it is clarified that the method of regulating states and resolving turbidity can play a role in improving glycolipid metabolism disorder by regulating lipid metabolism disorder, insulin resistance, bile acid metabolism abnormality, intestinal bacterial flora, and its metabolite abnormality and other mechanisms of action.

Objective:The causal relationship between eczema and autoimmune diseases has not been previously reported.This study aims to evaluate the causal relationship between eczema and autoimmune diseases. Methods:The two-sample Mendelian randomization(MR)method was used to assess the causal effect of eczema on autoimmune diseases.Summary data from the Genome-Wide Association Study Catalog(GWAS)were obtained from the Integrative Epidemiology Unit(IEU)database.For eczema and autoimmune diseases,genetic instrument variants(GIVs)were identified according to the significant difference(P<5×10-8).Causal effect estimates were generated using the inverse-variance weighted(IVW)method.MR Egger,maximum likelihood,MR-PRESSO,and MR-RAPS methods were used for alternative analyses.Sensitivity tests,including heterogeneity,horizontal pleiotropy,and leave-one-out analyses,were performed.Finally,reverse causality was assessed. Results:Genetic susceptibility to eczema was associated with an increased risk of Crohn's disease(OR=1.444,95%CI 1.199 to 1.738,P<0.001)and ulcerative colitis(OR=1.002,95%CI 1.001 to 1.003,P=0.002).However,no causal relationship was found for the other 6 autoimmune diseases,including systemic lupus erythematosus(SLE)(OR=0.932,P=0.401),bullous pemphigoid(BP)(OR=1.191,P=0.642),vitiligo(OR=1.000,P=0.327),multiple sclerosis(MS)(OR=1.000,P=0.965),ankylosing spondylitis(AS)(OR=1.001,P=0.121),rheumatoid arthritis(RA)(OR=1.000,P=0.460).Additionally,no reverse causal relationship was found between autoimmune diseases and eczema. Conclusion:Eczema is associated with an increased risk of Crohn's disease and ulcerative colitis.No causal relationship is found between eczema and SLE,MS,AS,RA,BP,or vitiligo.
