A systematic review of auricular therapy for poststroke cognitive impairment and dementia: A protocol for systematic review and meta-analysis.

BACKGROUND: Post-stroke cognitive impairment and dementia (PSCID) is the main source of morbidity and mortality after stroke worldwide. It is one consequence of ischemic stroke, intracerebral hemorrhage, or subarachnoid hemorrhage. Cognitive impairment and dementia after the clinical stroke may contribute to the clinical expression of PSCID, which are prevalent clinical symptoms, especially in the elderly. Current problems in the field of PSCID are related to a lack of harmonization of the classification and definition, deficiency of well-defined diagnosis, deficiency of standardized and objective treatment plans, etc. Auricular therapy can effectively improve the symptoms of patients with PSCID. However, there has been no systematic review of auricular therapy for PSCID. This study aimed to evaluate the efficacy and safety of auricular therapy in patients with PSCID. METHODS: Before December 2022, a systematic literature search was conducted using the following databases: PubMed, Embase, SinoMed (previously called the Chinese Biomedical Database), Web of Science, Chinese National Knowledge Infrastructure, and Wanfang Database. Review Manager software (version 5.3) will be used for statistical analysis; otherwise, descriptive analysis or subgroup analysis will be conducted. The quality of evidence for outcomes will be assessed with the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: This meta-analysis further confirmed the beneficial effects of auricular therapy in patients with PSCID. CONCLUSION: This study investigated the efficacy and safety of auricular therapy in patients with PSCID, providing clinicians and patients with additional options for this disease.

Acupuncture for diabetic neuropathic pain: A protocol for systematic review and meta analysis.

BACKGROUND: Diabetic neuropathic pain (DNP) is a common complication of diabetes mellitus, it severely affects the quality of life of Diabetic patients. Acupuncture is proofed to have favorable effects in treating DNP, however, evidence needs to be gathered and interpreted. We will make a comprehensive review of clinical trials concerning acupuncture in treating DNP and do meta-analysis if possible. METHOD: The following databases will be searched from the inception to September 2020: PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wan-Fang Database, and Chinese Scientific Journal Database. RCTs that evaluated acupuncture for patients with DNP will be included. The primary outcome will be patient-reported pain intensity using validated scales or verbal reporting. The secondary outcomes including the Toronto clinical scoring system, Sensory Nerve Conduction Velocity, Motor Nerve Conduction Velocity, and quality of life. The study selection, data extraction, and study quality evaluation will be performed independently by 2 researchers. A meta-analysis will be performed using RevMan V5.3 statistical software if possible; otherwise, descriptive analysis or subgroup analysis will be conducted. The quality of evidence for outcomes will be assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: This study will evaluate the effect and safety of acupuncture in treating DNP. CONCLUSIONS: The evidence we generated from the present study will provide more options for DNP management in clinical practice. SYSTEMATIC REVIEW REGISTRATION: INPLASY202090043.

A new 5(6→7)abeo-sterol from Podocarpus fleuryi.

A new 5(6→7)abeo-sterol, podosterol (1), together with 20 known compounds, were isolated from the leaves of Podocarpus fleuryi. Their structures were elucidated by means of extensive spectroscopic analysis. Podosterol was assessed for its cytotoxicity against five human tumor cell lines (HL-60, SMMC-7721, A-549, MCF-7, and SW-480), and the result showed that it had no activity.
