Sishen Pill and its active phytochemicals in treating inflammatory bowel disease and colon cancer: an overview.

The incidence of inflammatory bowel disease (IBD) and the associated risk of colon cancer are increasing globally. Traditional Chinese medicine (TCM) treatment has unique advantages. The Sishen Pill, a common Chinese patented drug used to treat abdominal pain and diarrhea, consists mainly of Psoraleae Fructus, Myristicae Semen, Euodiae Fructus, and Schisandra Chinensis. Modern research has confirmed that Sishen Pill and its active secondary metabolites, such as psoralen, myristicin, evodiamine, and schisandrin, can improve intestinal inflammation and exert antitumor pharmacological effects. Common mechanisms in treating IBD and colon cancer mainly include regulating inflammation-related signaling pathways such as nuclear factor-kappa B, mitogen-activated protein kinase, phosphatidylinositol 3-kinase, NOD-like receptor heat protein domain-related protein 3, and wingless-type MMTV integration site family; NF-E2-related factor 2 and hypoxia-inducible factor 1α to inhibit oxidative stress; mitochondrial autophagy and endoplasmic reticulum stress; intestinal immune cell differentiation and function through the Janus kinase/signal transducer and activator of transcription pathway; and improving the gut microbiota and intestinal barrier. Overall, existing evidence suggests the potential of the Sishen pill to improve IBD and suppress inflammation-to-cancer transformation. However, large-scale randomized controlled clinical studies and research on the safety of these clinical applications are urgently required.

Contrasting effects of music therapy and aromatherapy on perioperative anxiety: A systematic review and meta-analysis.

INTRODUCTION: Music therapy and aromatherapy have been demonstrated effective for perioperative anxiety. However, the available studies have indicated discordant results about which adjunct treatment is better for perioperative anxiety. Therefore, we conducted this meta-analysis to explore the contrasting effects between them. METHODS: Six electronic databases were searched for clinical trials evaluating the efficacy of music therapy compared with aromatherapy in alleviating perioperative anxiety. The primary outcome was the postintervention anxiety level. Secondary outcomes included differences in blood pressure and heart rate before and after the intervention as well as pain scores at intraoperative and postoperative time points. The study protocol was registered on PROSPERO (CRD42021249737). RESULTS: Twelve studies (894 patients) were included. The anxiety level showed no statistically significant difference (SMD, 0.28; 95% CI: -0.12, 0.68; P =.17). The analysis of blood pressure and heart rate also did not identify statistically significant differences. Notably, the pain scores at the intraoperative time point suggested that aromatherapy was superior to music therapy (WMD, 0.29 cm; 95% CI: 0.05, 0.52; P =.02), while those at 4 hours after surgery indicated the opposite results (WMD, -0.48 cm; 95% CI: -0.60, -0.36; P <.001). CONCLUSION: Low-to-moderate quality evidence suggests that music therapy and aromatherapy have similar potential to relieve perioperative anxiety. The potential data indicates that the two therapies have different benefits in intervention duration and age distribution. More direct high-quality comparisons are encouraged in the future to verify this point.

Pharmacodynamic components and mechanisms of ginger (Zingiber officinale) in the prevention and treatment of colorectal cancer.

ETHNOPHARMACOLOGICAL RELEVANCE: Ginger is a "medicine-food homology" natural herb and has a longstanding medicinal background in treating intestinal diseases. Its remarkable bioactivities, including anti-inflammatory, antioxidant, immunoregulatory, flora regulatory, intestinal protective, and anticancer properties, make it a promising natural medicine for colorectal cancer (CRC) prevention and treatment. AIM OF THE REVIEW: The purpose is to review the relevant literature on ginger and pharmacodynamic components for CRC prevention and treatment, summarize the possible mechanisms of ginger from clinical studies and animal and in vitro experiments, to provide theoretical support for the use of ginger preparations in the daily prevention and clinical treatment of CRC. MATERIALS AND METHODS: Literatures about ginger and CRC were searched from electronic databases, such as PubMed, Web of Science, ScienceDirect, Google Scholar and China National Knowledge Infrastructure (CNKI). RESULTS: This article summarizes the molecular mechanisms of ginger and its pharmacodynamic components in the prevention and treatment of CRC, including anti-inflammatory, antioxidant, immunoregulatory, flora regulatory, intestinal protective, inhibit CRC cell proliferation, induce CRC cell cycle blockage, promote CRC cell apoptosis, suppress CRC cell invasion and migration, enhance the anticancer effect of chemotherapeutic drugs. CONCLUSIONS: Ginger has potential for daily prevention and clinical treatment of CRC.

Pharmacologic effects approach of essential oils and their components on respiratory diseases.

ETHNOPHARMACOLOGICAL RELEVANCE: Essential oils (EOs) are concentrated hydrophobic liquids with volatility and a unique aroma. Formed by aromatic plants as secondary metabolites, EOs have been used as traditional medicines to treat various health problems worldwide. Historical records show that herbs rich in EOs have been widely used to treat respiratory diseases in China, Europe, and many other regions. AIM OF THE REVIEW: This review summarizes the traditional applications and modern pharmacological mechanisms of EOs derived from aromatic herbs and their active ingredients in respiratory diseases in preclinical and clinical trials through multitarget synergy. MATERIALS AND METHODS: Information about EOs and respiratory diseases was collected from electronic databases, such as ScienceDirect, Web of Science, PubMed, Google Scholar, Baidu Scholar, and the China National Knowledge Infrastructure (CNKI). RESULTS: This review presents the preventive and therapeutic effects of EOs on respiratory diseases, including chronic obstructive pulmonary disease, bronchial asthma, acute lung injury, pulmonary infection, and pulmonary fibrosis. The molecular mechanisms of EOs in treating different lung diseases are summarized, including anti-inflammation, anti-oxidation, mucolytic, and immune regulatory mechanisms. CONCLUSIONS: EOs show potential as supplements or substitutes for treating lung diseases.

Does Inhaled Methoxyflurane Implement Fast and Efficient Pain Management in Trauma Patients? A Systematic Review and Meta-Analysis.

INTRODUCTION: Evidence on the use of inhaled methoxyflurane in the management of trauma pain is conflicting and obfuscated. This study aimed to determine the efficacy and safety of inhaled methoxyflurane for trauma pain on the basis of published randomized controlled trials (RCTs). METHODS: RCTs assessing the efficacy of methoxyflurane in adults or adolescents with acute trauma pain published in PubMed, Web of Science, Embase, Cochrane Library, and Google Scholar were searched. The control groups were those that received placebo or standard analgesic treatment (SAT). The primary outcome was the change from baseline in pain scores during the first 30 min of treatment. Secondary outcomes included time to first pain relief, the proportion of patients experiencing pain relief, rescue analgesia rate, the treatment satisfaction of patients and investigators, and the methoxyflurane-related treatment-emergent adverse events (TEAEs). RESULTS: A total of nine RCTs (1806 patients) were identified. Results revealed that methoxyflurane provided a clinically unimportant benefit by improving the mean difference of change from baseline in pain intensity (from - 0.44 to - 1.23 cm, p < 0.001) at various time points within the first 20 min compared to control treatment. Besides, methoxyflurane decreased the time of onset of pain relief (mean difference - 5.29 min; 95% CI - 6.97 to - 3.62) and the proportion of patients who needed rescue analgesic medication (risk ratio 1.41; 95% CI 1.17-1.70) despite it increasing the risk of non-severe TEAEs (risk ratio 3.09; 95% CI 1.72-5.57). Notably, the benefit of almost all secondary pain-related outcomes was rendered clinically nonsignificant between methoxyflurane and SAT strata besides the time of onset of pain relief. The quality of evidence was low or very low in all outcomes. CONCLUSIONS: In emergency situations without effective therapy, this systematic review and meta-analysis provides low-quality evidence that methoxyflurane can be used as a rapid-acting and effective treatment for acute trauma pain, although its utilization is associated a risk of non-severe TEAEs. However, the current evidence does not support the notion that inhaled methoxyflurane offered superior analgesic efficacy to SAT. CLINICAL TRIAL NUMBER: PROSPERO registration number CRD42020223000.
