Rhizoma coptidis (CR) is traditionally used for treating gastrointestinal diseases. Wine-processed CR (wCR), zingiber-processed CR (zCR), and evodia-processed CR (eCR) are its major processed products. However, the related study of their specific mechanisms is very limited, and they need to be further clarified. The aim of this study is to compare the intervening mechanism of wCR/zCR/eCR on rats via faecal metabolomics and 16S rDNA gene sequencing analysis. First, faecal samples were collected from the control and CR/wCR/zCR/eCR groups. Then, a metabolomics analysis was performed using UHPLC-Q/TOF-MS to obtain the metabolic profile and significantly altered metabolites. The 16S rDNA gene sequencing analysis was carried out to analyze the composition of gut microbiota and screen out the significantly altered microbiota at the genus level. Finally, a pathway enrichment analysis of the significantly altered metabolites via the KEGG database and a functional prediction of relevant gut microbes based on PICRUSt2 software were performed in combination. Together with the correlation analysis between metabolites and gut microbiota, the potential intervening mechanism of wCR/zCR/eCR was explored. The results suggested that wCR played a good role in maintaining immune homeostasis, promoting glycolysis, and reducing cholesterol; zCR had a better effect on protecting the integrity of the intestinal mucus barrier, preventing gastric ulcers, and reducing body cholesterol; eCR was good at protecting the integrity of the intestinal mucus barrier and promoting glycolysis. This study scientifically elucidated the intervening mechanism of wCR/zCR/eCR from the perspective of faecal metabolites and gut microbiota, providing a new insight into the processing mechanism research of Chinese herbs.

Purpose: The purpose of this study was to explore the pharmacokinetics (PK) characteristics and safety of continuous lidocaine infusion during hepatectomy in liver cancer patients. Methods: This study included thirty-five patients undergoing laparoscopic hepatectomy from January 2021 to December 2021. Patients received a short infusion of 1% lidocaine at a dose of 1.5 mg/kg based on ideal body weight, followed by a continuous infusion of 1 mg/kg/h during the operation. The plasma concentrations of lidocaine and its active metabolites were measured using validated ultra-performance liquid chromatography-tandem mass spectrometry. Safety was evaluated by monitoring and recording all adverse events (AEs). Results: The concentrations of lidocaine were within the safe range, except one patient's concentration of lidocaine which reached the toxic range (> 5 μg/mL). The mean half-life (T1/2), the mean time to maximum observed concentration (Tmax), and the mean maximum observed concentration (Cmax) of lidocaine were 3.96 h, 2.85 h, and 2030 ng/mL, respectively; the mean T1/2, Tmax, and Cmax (n = 32) of MEGX were 6.59 h, 5.05 h, and 333.28 ng/mL, respectively; and the mean T1/2, Tmax, and Cmax of GX (n = 18) were 25.98 h, 7.33 h, and 75.81 ng/mL. Although eight subjects with AEs were reported, there were no serious AEs or deaths. No patients had serious postoperative complications. No deaths occurred within 30 days after the operation. Conclusions: Under the administration regimen of this study, intravenous infusion of lidocaine is safe and tolerable for liver cancer patients with laparoscopic hepatectomy. Fine safety and PK characteristics support the application of lidocaine in such patients and further clinical research. Trial registration: China Clinical Trial Registration Center (ChiCTR2100042730), Registered 27 January 2021. [ABSTRACT FROM AUTHOR]

Objectives: To investigate public awareness of colorectal cancer (three components: total knowledge, confidence and anticipated delay) in the Chinese population, to explore factors associated with total knowledge and to elucidate relationships among three components of public awareness of colorectal cancer. Methods: We recruited 562 adult Chinese participants with no history of colorectal cancer between March and May 2020 by convenience sampling method. Data were collected online using a self‐designed demographic questionnaire and a simplified Chinese version of the Bowel Cancer Awareness Measure. Univariate analysis and multivariate linear regression were applied. Results: The mean score for total knowledge was 10.56 (SD: 5.89). Over half of the participants (58.2%) lacked confidence about detecting warning signs. For 42.7% of participants, the anticipated delay was not within the acceptable range (2 weeks). Totally eight demographic variables were identified as significant predictors of total knowledge, accounting for 36.2% of the variance. Total knowledge was positively correlated with confidence (r = 0.126, p < 0.01) and negatively associated with anticipated delay (F = 8.891, p < 0.01). Conclusion: Public awareness of colorectal cancer was low in the Chinese population. Hence, educational interventions targeted for improving knowledge, enhancing individuals' confidence in detecting symptoms and reducing barriers to seeking medical help may be urgently required.

Aims and objectives: To reveal nurses’ self‐reported practice of managing chest tubes and to define decision‐makers for these practices. Background: No consensus exists regarding ideal chest‐tube management strategy, and there are wide variations of practice based on local policies and individual preferences, rather than standardised evidence‐based protocols. Design: This article describes a cross‐sectional study. Methods: Questionnaires were emailed to 31 hospitals in Tianjin, and the sample consisted of 296 clinical nurses whose work included nursing management of chest drains. The questionnaire, which was prepared by the authors of this research, consisted of three sections, including a total of 22 questions that asked for demographic information, answers regarding nursing management that reflected the practice they actually performed and who the decision‐makers were regarding eight chest‐drain management procedures. McNemar's test was used to analyse the data. Results: The results indicated that most respondents thought that it was necessary to manipulate chest tubes to remove clots impeding unobstructed drainage (91.2%). Most respondents indicated that dressings would be changed when the dressing was dysfunctional. At the same time, more than half of respondents approved of changing dressings routinely, and the frequency of changing dressings varied. When drainage was employed for pleural effusion and for a pneumothorax, 64.6% and 94.5% of respondents, respectively, considered that underwater seal‐drainage bottles should be changed routinely, and the frequency of changing bottles both varied. The results indicated that nurses were the primary decision‐makers in the replacement of chest tubes, manipulation of chest tubes and monitoring of drainage fluid. Conclusions: There was considerable variation in respondents’ self‐reported clinical nursing practice regarding management of chest drains. The rationale on which respondents’ practices were based also varied greatly. This study indicated that nurses were the primary decision‐makers for three of eight procedures regarding management of chest drains, which reflects that clinical nurses’ decision‐making power regarding management of chest drains was weak. Relevance to clinical practice: This study describes the nurse‐reported practices of Chinese nurses from Tianjin, including changing and selecting dressing types, manipulating chest tubes, clamping drains and replacing drainage bottles, and the study defines who the decision‐makers were for these interventions. By focusing on nurses’ self‐report of behaviours in managing chest drains (actual nursing practice vs. nursing knowledge), this article also relates the literature to the research findings and denotes the gaps in knowledge for future research.

Implementation of clinical practice guidelines (CPG) is a complex and challenging task. Computer technology, including artificial intelligence (AI), has been explored to promote the CPG implementation. This study has reviewed the main domains where computer technology and AI has been applied to CPG implementation. PubMed, Embase, Web of science, the Cochrane Library, China National Knowledge Infrastructure database, WanFang DATA, VIP database, and China Biology Medicine disc database were searched from inception to December 2021. Studies involving the utilization of computer technology and AI to promote the implementation of CPGs were eligible for review. A total of 10429 published articles were identified, 117 met the inclusion criteria. 21 (17.9%) focused on the utilization of AI techniques to classify or extract the relative content of CPGs, such as recommendation sentence, condition-action sentences. 47 (40.2%) focused on the utilization of computer technology to represent guideline knowledge to make it understandable by computer. 15 (12.8%) focused on the utilization of AI techniques to verify the relative content of CPGs, such as conciliation of multiple single-disease guidelines for comorbid patients. 34 (29.1%) focused on the utilization of AI techniques to integrate guideline knowledge into different resources, such as clinical decision support systems. We conclude that the application of computer technology and AI to CPG implementation mainly concentrated on the guideline content classification and extraction, guideline knowledge representation, guideline knowledge verification, and guideline knowledge integration. The AI methods used for guideline content classification and extraction were pattern-based algorithm and machine learning. In guideline knowledge representation, guideline knowledge verification, and guideline knowledge integration, computer techniques of knowledge representation were the most used.

A phytochemical study on a 70% EtOH extract of dried roots of Polygonum multiflorum resulted in the isolation of four undescribed stilbene glucosides, namely multiflorumisides H K (1 – 4). The structures of the natural products were elucidated by 1D and 2D nuclear magnetic resonance (NMR) as well as mass spectroscopy analyses. Among them, multiflorumiside J (3) and multiflorumiside K (4) belong to rare tetramer stilbene glucosides. Moreover, the in vitro inhibitory activities against protein tyrosine phosphatase 1B (PTP1B) were evaluated and the putative biosynthetic pathway was proposed. Notably, compounds 1 – 4 showed the inhibitory activity against PTP1B with the IC 50 values of 1.2, 1.7, 1.5 and 4.6 μm, respectively. Based on the obtained results, stilbene glucosides could be the potential PTP1B inhibitors of P. multiflorum. Unlabelled Image • Four previously undescribed stilbene glucosides were isolated from P. multiflorum. • Multiflorumiside J (3) and multiflorumiside K (4) belong to rare tetramer stilbene glucosides. • Structures were determined by extensive spectroscopic analyses. • Multiflorumisides H K (1 – 4) exhibited potent PTP1B inhibitory activities.
