OBJECTIVES: To evaluate the efficacy of acupuncture in the treatment of postoperative gastrointestinal dysfunction(POGD) of colorectal cancer. METHODS: Randomized controlled trials of acupuncture in the treatment of POGD were retrieved from 7 databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP Chinese Journal Service Platform, WanFang Data Knowledge Service Platform, and China Biology Medicine disc. The search period ranged from the inception of the databases to November 10th, 2022. The quality of the included literature was assessed using the Cochrane bias risk assessment tool and the modified Jadad scale. Meta analysis was conducted using RevMan 5.4. Regression analysis and bias risk analysis were performed using Stata 16.0. Trial sequential analysis was conducted using TSA 0.9 software. RESULTS: A total of 27 randomized controlled trials involving 2 629 patients were included. Intervention measures included manual acupuncture, electroacupuncture, transcutaneous acupoint electrical stimulation, warm acupuncture, and thumb-tack needle. The results showed that acupuncture treatment significantly reduced time to tolerance of liquid diet after surgery (MD=-13.70, 95% CI=ï¼»-17.94, -9.46ï¼½, P<0.000 01), time to first defecation (MD=-18.20, 95% CI=ï¼»-22.62, -13.78ï¼½, P<0.000 01), time to first flatus (MD=-16.31, 95% CI=ï¼»-20.32, -12.31ï¼½, P<0.000 01), time to bowel sounds recovery (MD=-11.91, 95% CI=ï¼»-14.01, -9.81ï¼½, P<0.000 01), and length of hospital stay (MD=-1.49, 95% CI=ï¼»-2.27, -0.70ï¼½, P=0.000 2). Regression analysis indicated that cancer type, study quality and number of acupuncture were the main sources of heterogeneity. Bias analysis suggested potential publication bias risks. Trial sequential analysis indicated that the required number of cases had been met and the conclusion was reliable. CONCLUSIONS: Acupuncture is an effective intervention for promoting gastrointestinal recovery in patients undergoing colorectal cancer surgery. Further large-sample and well-designed clinical trials are still needed to compare different acupuncture techniques.

How do the main components influence the VOCs emission characteristics and formation pathways during moso bamboo heat treatment?

Bamboo heat treatment will cause plenty of release of volatile organic compounds (VOCs) into the atmosphere which are important precursors for ozone (O3) formation. In this study, dewaxed bamboo was heat-treated at 180 °C for 2 h to investigate the emission characteristics and the formation pathways of VOCs during heat treatment by removing different main components. The results showed that aldehydes (22.61%-57.54%) and esters (14.64%-38.88%) are the primary VOCs released during heat treatment. These compounds mainly originate from the degradation of hemicellulose, lignin, cellulose, and the linkage bonds between them in bamboo. During the bamboo heat treatment, the degradation of CO, CH, and CO bonds in hemicellulose results in the release of 5-hydroxymethylfurfural, 3-furfural, and 1-(+)-ascorbic acid 2,6-dihexadecanoate. The breakage of benzene ring group and the CO and CH bonds of lignin leading to the emission of VOCs including m-Formylphenol, Vanillin, and Syringaldehyde. The degradation of aliphatic CH, CC, and CO bonds in the amorphous region of cellulose contributes to an enhanced release of alcohols, olefins, and alkanes. It is calculated that acids (28.92%-59.47%), esters (10.10%-22.03%) and aldehydes (17.88%-39.91%) released during heat treatment contributed more to Ozone Formation Potential (OFP).

Knowledge domain and emerging trends in diabetic cardiomyopathy: A scientometric review based on CiteSpace analysis.

Objective: To review the literature related to diabetic cardiomyopathy (DCM), and investigate research hotspots and development trends of this field in the relevant studies based on CiteSpace software of text mining and visualization in scientific literature. Methods: The relevant literature from the last 20 years was retrieved from the Web of Science (WoS) Core Collection database. After manual selection, each document record includes title, authors, year, organization, abstract, keywords, citation, descriptors, and identifiers. We imported the downloaded data into CiteSpace V (version 5.8.R2) to draw the knowledge map and conduct cooperative network analysis, cluster analysis, burst keyword analysis, and co-citation analysis. Results: After manual screening, there were 3,547 relevant pieces of literature published in the last 18 years (from 2004 to 2021), including 2,935 articles and reviews, which contained 15,533 references, and the number was increasing year by year. The publications of DCM were dedicated by 778 authors of 512 institutions in 116 countries. The People's Republic of China dominated this field (1,117), followed by the USA (768) and Canada (176). In general, most articles were published with a focus on "oxidative stress," "heart failure," "diabetic cardiomyopathy," "dysfunction," "cardiomyopathy," "expression," "heart," "mechanism," and "insulin resistance." Then, 10 main clusters were generated with a modularity Q of 0.6442 and a weighted mean silhouette of 0.8325 by the log-likelihood ratio (LLR) algorithm, including #0 heart failure, #1 perfused heart, #2 metabolic disease, #3 protective effect, #4 diabetic patient, #5 cardiac fibrosis, #6 vascular complication, #7 mitochondrial dynamics, #8 sarcoplasmic reticulum, and #9 zinc supplementation. The top five references with the strongest citation bursts include "Boudina and Abel", "Jia et al.", "Fang et al.", "Poornima et al.", and "Aneja et al.". Conclusion: The global field of DCM has expanded in the last 20 years. The People's Republic of China contributes the most. However, there is little cooperation among authors and institutions. Overall, this bibliometric study identified the hotspots in DCM research, including "stress state," "energy metabolism," "autophagy," "apoptosis," "inflammation," "fibrosis," "PPAR," etc. Thus, further research focuses on these topics that may be more helpful to identify, prevent DCM and improve prophylaxis strategies to bring benefit to patients in the near future.

Prediction of the Active Components and Mechanism of Forsythia suspensa Leaf against Respiratory Syncytial Virus Based on Network Pharmacology.

Objective: Forsythia suspensa leaf (FSL) has been used as a health tea in China for centuries. Previous experiments have proved that FSL extract has a good effect on the antirespiratory syncytial virus (RSV) in vitro, but its exact mechanism is not clear. Therefore, this study aims to determine the active components and targets of FSL and further explore its anti-RSV mechanism. Methods: UPLC-Q-Exactive-MS was used to analyze the main chemical components of FSL. The compound disease target network, PPI, GO, and KEGG were used to obtain key targets and potential ways. Then, the molecular docking was verified by Schrödinger Maestro software. Next, the cell model of RSV infection was established, and the inhibitory effect of each drug on RSV was detected. Finally, western blotting was used to detect the effect of the active components of FSL on the expression of PI3K/AKT signaling pathway-related protein. Results: UPLC-Q-Exactive-MS analysis showed that there were 67 main chemical constituents in FSL, while network pharmacological analysis showed that there were 169 anti-RSV targets of the active components in FSL, involving 177 signal pathways, among which PI3K/AKT signal pathway played an important role in the anti-RSV process of FSL. The results of molecular docking showed that cryptochlorogenic acid, phillyrin, phillygenin, rutin, and rosmarinic acid had higher binding activities to TP53, STAT3, MAPK1, AKT1, and MAPK3, respectively. In vitro experiments showed that phillyrin and rosmarinic acid could effectively improve the survival rate of RSV-infected cells, increase the expression level of PI3K, and decrease the expression level of AKT. Conclusion: The active ingredients of FSL, phillyrin, and rosmarinic acid can play an anti-RSV role by inhibiting PI3K/AKT signaling pathway. This study provides reliable theoretical and experimental support for the anti-RSV treatment of FSL.

Treatment of Lung Cancer with Orally Administered Chinese Herbal Medicine: An Evidence Map between 1970-2020.

OBJECTIVE: Through showing the full picture of double-arm controlled clinical research and systematic review evidence in the field of orally administrated Chinese herbal medicine (CHM) for treatment of lung cancer, to provide a reference for future clinical research and to indicate a direction for future systematic reviews. METHODS: A comprehensive search of clinical controlled studies was performed regarding orally administered CHM treatment for lung cancer published from January 1970 to September 2020. The language was restricted to Chinese and English. Relevant data were extracted, the quality of systematic reviews was evaluated, and the research evidence was visually displayed. RESULTS: Randomized controlled trials were the most common type of research design. The research sample sizes were typically small. Oral CHM showed certain curative advantages in treating lung cancer. The key stages in oral CHM intervention for lung cancer are chemotherapy, radiotherapy, and late palliative treatment. The advantageous outcomes of oral CHM treatment of lung cancer are the short-term efficacy, quality of life, and adverse reactions. The perioperative stage, overall survival, pharmacoeconomic evaluation, and Chinese medicine decoctions are weak research areas. CONCLUSIONS: CHM has staged and therapeutic advantages in treating lung cancer. The overall methodological quality is poor, and the level of evidence requires improvement. It is necessary to carry out large-scale, standardized, and higher-quality research in the superior and weak areas of CHM treatment of lung cancer.
