Key Targets and Molecular Mechanisms of Active Volatile Components of Rabdosia rubescens in Gastric Cancer Cells.

OBJECTIVE: To examine the effect and mechanism of volatile components of Rabdosia rubescens on gastric cancer. METHODS: Gas chromatography-mass spectrometry was used to detect and identify the volatile components of R. rubescens. The network pharmacology method was used to analyze the targets of volatile components of R. rubescens in gastric cancer and to reveal their molecular mechanisms. The effects of volatile components of R. rubescens on gastric cancer cells were verified by biological experiments. RESULTS: Thirteen volatile components of R. rubescens were selected as pharmacologically active components. The 13 active components had 83 targets in gastric cancer, and a Traditional Chinese Medicine-component-targets gastric cancer network was successfully constructed. Five core targets were obtained: TNF, IL1B, MMP9, PTGS2 and CECL8. The volatile components inhibited the proliferation of gastric cancer cells in a concentration-dependent manner and promoted the apoptosis of gastric cancer cells. The volatile components reduced the levels of TNF, IL1B, MPP9, and PTGS2 in a concentration-dependent manner. CONCLUSION: Our study demonstrates the effects of volatile components in R. rubescens on gastric cancer and provides preliminary findings on their mechanisms of action.

Assessment of the efficacy of tuina on treating cervicogenic headache: A protocol for systematic review and meta-analysis.

BACKGROUND: Cervicogenic headache is a secondary headache characterized by unilateral headache, symptoms, and signs of neck involvement. It is often worsened by neck movement, sustained awkward head position, or external pressure over the upper cervical or occipital region on the symptomatic side. In this systematic review, we aimed to evaluate the efficacy and safety of massage therapy for the treatment of cervicogenic headache. METHODS: We searched the China National Knowledge Infrastructure, Chinese Scientific Journal Database, Wanfang Database, China Doctoral Dissertations Full-Text Database, China Master's Theses Full-Text Database, Cochrane Central Register of Controlled Trials, PubMed, and Embase. We will select all eligible studies published on or before April 1, 2021. We will use Review Manager 5.4, provided by the Cochrane Collaborative Network for statistical analysis. We then assessed the quality and risk of the included studies and observed the outcome measures. RESULTS: This meta-analysis further confirmed the benefits of tuina in the treatment of cervicogenic headache. CONCLUSION: The purpose of this meta-analysis was to explore the effect of tuina on patients with cervicogenic headache and to provide more options for clinicians and patients to treat cervicogenic headache. ETHICS AND DISSEMINATION: This systematic review will evaluate the efficacy and safety of tuina in the treatment of cervicogenic headache. Since all the data included were published, the systematic review did not require ethical approval. REGISTRATION NUMBER: INPLASY202150053.

Acupuncture combine with Tuina for diabetic peripheral neuropathy: A protocol for a systematic review and meta-analysis.

BACKGROUND: Diabetic peripheral neuropathy (DPN) is one of the most common microvascular complications of diabetes mellitus, with an incidence ranging from 60% to 90%. With the change in modern dietary structure, the incidence of diabetes is increasing year by year, and DPN is also on the rise. Acupuncture and Tuina treatments are often combined to treat DPN; however, there has been no meta-analysis on their synergistic effect; therefore, we aimed to perform a systematic review and meta-analysis to estimate the effectiveness of acupuncture combined with Tuina in DPN treatment. METHODS: Nine electronic databases were retrieved for this study. The English databases mainly retrieved PubMed, Web of Science, Embase, AMED, and the Cochrane Library, while the CNKI, VIP, CBM, and Wanfang databases were used to retrieve the Chinese literature; there was no definite time limit for the retrieval literature, and the languages were limited to Chinese and English. We will consider articles published between database initiation and November 2021. We used Review Manager 5.4 software provided by the Cochrane Collaborative Network for statistical analysis. We then assessed the quality and risk of the included studies and observed the outcome measures. RESULTS: This study provides a high-quality synthesis to assess the effectiveness and safety of acupuncture combined with Tuina for treating DPN. CONCLUSION: This systematic review provided evidence to determine whether acupuncture combined with Tuina is an effective and safe intervention for patients with DPN. ETHICS AND DISSEMINATION: The protocol for this systematic review does not require ethical approval because it does not involve humans. This article will be published in peer-reviewed journals and presented at relevant conferences. SYSTEMATIC REVIEW REGISTRATION: INPLASY2021110017.

Feasible conversion of solid waste bauxite tailings into highly crystalline 4A zeolite with valuable application.

Bauxite tailings are a major type of solid wastes generated in the flotation process. The waste by-products caused significant environmental impact. To lessen this hazardous effect from poisonous mine tailings, a feasible and cost-effective solution was conceived and implemented. Our approach focused on reutilization of the bauxite tailings by converting it to 4A zeolite for reuse in diverse applications. Three steps were involved in the bauxite conversion: wet-chemistry, alkali fusion, and crystallization to remove impurities and to prepare porous 4A zeolite. It was found that the cubic 4A zeolite was single phase, in high purity, with high crystallinity and well-defined structure. Importantly, the 4A zeolite displayed maximum calcium ion exchange capacity averaged at 296 mg CaCO3/g, comparable to commercially-available zeolite (310 mg CaCO3/g) exchange capacity. Base on the optimal synthesis condition, the reaction yield of zeolite 4A from bauxite tailings achieved to about 38.43%, hence, this study will provide a new paradigm for remediation of bauxite tailings, further mitigating the environmental and health care concerns, particularly in the mainland of PR China.

Low concentrations of lidocaine for inguinal hernia repair under local infiltration anaesthesia.

OBJECTIVE: A randomized, double-blind, prospective, controlled study to determine the lowest concentration of lidocaine that provides satisfactory anaesthesia and analgesia for inguinal hernia repair. METHODS: Patients with inguinal hernia undergoing tension-free mesh repair under local infiltration anaesthesia were randomized to receive 0.25% (Group A), 0.33% (Group B) or 0.5% (Group C) lidocaine. Total dose and volume of lidocaine consumed and intraoperative visual analogue scale (VAS) pain scores were recorded for each patient. Each patient's degree of satisfaction and the incidence of anaesthesia- and procedure-related complications were recorded and assessed. RESULTS: A total of 120 patients were randomized. There were no between-group differences in median VAS scores, degree of satisfaction, volume of lidocaine consumed or incidence of complications. Patients in group A consumed significantly lower doses of lidocaine than those in both other groups. CONCLUSIONS: The mean dose of lidocaine consumed in group A was significantly lower but exerted similar efficacy to that in the other groups, and may lead to a lower risk of local anaesthetic toxicity.

[Multi-central clinical evaluation of ginger-partitioned moxibustion for treatment of leukopenia induced by chemotherapy].

OBJECTIVE: To prove the therapeutic effect of ginger-partitioned moxibustion on leukopenia induced by chemotherapy and effect on life quality of the patient with tumor after chemotherapy. METHODS: Randomized, controlled, multi-central cooperative method was used and the patients confirmed to the enrolled criteria were divided in-to two groups. The test group were treated with ginger-partitioned moxibustion at Dazhui (GV 14), Geshu (BL 17), Pishu (BL 20), etc.; and the control group with oral administration of Chinese patent medicine. RESULTS: Out of the 221 cases confirmed to program analysis, 113 cases were in the test group and 108 cases in the control group. After 10 days, the cured rate and the effective rate were 84.1% and 66.4% in the test group and 35.2% and 33.3% in the control group, respectively, with very significant differences between the two groups (both P < 0.01); fifteen days later, the therapeutic effects in the two groups were maintained. The two methods could improve clinical symptoms, with the test group being better than the control group. Any adverse response was not found in the two groups, and the injuries of functions of the heart, lung and kidney induced by chemotherapy had some improvement. CONCLUSION: The therapeutic effect of ginger-partitioned moxibustion on luekopenia induced by chemotherapy is reliable and is better than oral administration of Chinese patent medicine, with a better duplication.
