Effects of PC6 acupressure on acute and delayed nausea and vomiting induced by chemotherapy in patients with malignant neoplasm: a meta-analysis.

OBJECTIVE: Evaluating the intervention effect of PC6 acupressure on chemotherapy-induced acute, delayed nausea, and vomiting in malignant tumor patients. METHOD: Eleven databases had been retrieved from January 2010 through January 2022. The published meta-analysis literature was hand-searched, and the language was limited to English and Chinese. The protocol of this meta-analysis was registered with PROSPERO (registration number: CRD42022323693). Two reviewers independently selected relevant eligible articles, extracted data, and evaluated the risk of bias. Meta-analysis was statistically analyzed using software RevMan 5.3. RESULT: Ten randomized controlled trials with 975 patients were included. Only two studies were assessed as high quality; eight studies were evaluated as moderate. Meta-analysis showed that compared with the control group, PC6 acupressure reduced the occurrence number of acute (SMD = -0.39,95CI (-0.73, -0.05) P = 0.02), delayed (SMD = -0.51, 95% CI (-0.96, -0.05) P = 0.03) nausea and acute (SMD = -0.42,95% CI (-0.79, -0.06) P = 0.02), delayed (SMD = -0.37, 95% CI (-0.77, 0.03) P = 0.07) vomiting; it reduced the severity of acute (SMD = -0.34, 95% CI (-0.57, -0.11) P = 0.004), delayed (SMD = -0.79, 95% CI (-1.33, -0.25) P = 0.004) nausea and acute (SMD = -0.51, 95% CI (-0.79, -0.23) P = 0.0004), delayed (SMD = -0.50, 95% CI (-0.84, -0.17) P = 0.003) vomiting, while it did not reduced the experience time on acute and delayed CINV. CONCLUSION: The meta-analysis shows the effectiveness of PC6 acupressure in preventing and treating nausea and vomiting. Large, high-quality, well-designed randomized controlled trials are needed in the future to determine the efficacy of PC6 acupressure on chemotherapy-induced nausea and vomiting.

Effect of traditional Chinese medicine (TCM) on survival, quality of life, and immune function in patients with ovarian carcinoma: A protocol for systematic review and meta analysis.

BACKGROUND: Traditional Chinese medicine (TCM) has been widely applied as promising adjunctive drugs for ovarian carcinoma (OC) in China and other Asian countries. However, its exact clinical efficacy and safety is still not well investigated. In this study, we aimed to summarize the efficacy of TCM on survival, quality of life (QoL), and immune function in patients with OC through the meta-analysis. METHODS: Relevant clinical trials of TCM for the treatment OC patients will be searched in Cochrane Library, Web of Science, Google Scholar, PubMed, Medline, Embase, China Scientific Journal Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, and Wanfang Database from their inception to November 2020. Two researchers will perform data extraction and risk of bias assessment independently. The clinical outcomes, including overall survival (OS), QoL, immune function, tumor markers, and adverse events, were systematically evaluated by using Review Manager 5.3 and Stata 14.0 statistical software. RESULTS: The results of this study will provide high-quality evidence for the effect of TCM on survival, QoL and immune function in patients with OC. CONCLUSION: The conclusions of this meta-analysis will be published in a peer-reviewed journal, and draw an objective conclusion of the efficacy of TCM on survival, QoL, and immune function in patients with OC.

Comprehensive HILIC × RPLC with mass spectrometry detection for the analysis of saponins in Panax notoginseng.

A comprehensive off-line two-dimensional liquid chromatography (2D-LC) method coupling hydrophilic interaction liquid chromatography (HILIC) and reversed phase liquid chromatography (RPLC) was developed in this study to detect as many saponins as possible in extracts of Panax notoginseng. The orthogonality of the 2D HILIC × RPLC was up to 81%, and the peak capacity was 10200. In total, 224 saponins were found, and some of them were trace amounts. Besides, a screening table designed by adding molecular weights of possible aglycones and sugars was constructed to help rapidly characterize the saponins using MS information. Unfortunately, the structure of saponins could not be identified by using only MS information.
