RESUMEN
OBJECTIVE: To identify specific Chinese medicines (CMs) that may benefit patients with gastroesophageal reflux disease (GERD), and explore the action mechanism. METHODS: Domestic and foreign literature on the treatment of GERD with CMs was searched and selected from China National Knowledge Infrastructure, China Science and Technology Journal Database, Wanfang Database, and PubMed from October 1, 2011 to October 1, 2021. Data from all eligible articles were extracted to establish the database of CMs for GERD. Apriori algorithm of data mining techniques was used to analyze the rules of herbs selection and core Chinese medicine formulas were identified. A system pharmacology approach was used to explore the action mechanism of these medicines. RESULTS: A total of 278 prescriptions for GERD were analyzed, including 192 CMs. Results of Apriori algorithm indicated that Evodiae Fructus and Coptidis Rhizoma were the highest confidence combination. A total of 32 active ingredients and 66 targets were screened for the treatment of GERD. Enrichment analysis showed that the mechanisms of action mainly involved pathways in cancer, fluid shear stress and atherosclerosis, advanced glycation end product (AGE), the receptor for AGE signaling pathway in diabetic complications, bladder cancer, and rheumatoid arthritis. CONCLUSION: Evodiae Fructus and Coptidis Rhizoma are the core drugs in the treatment of GERD and the potential mechanism of action of these medicines includes potential target and pathways.

The current study analysed concentrations of furan and its derivatives in coffee products commercially available in China based on an improved headspace gas chromatography-mass spectrometry (HS-GC-MS) method and estimated health risks. A total of 101 samples of coffee products on the Chinese market was analysed. Furan (98%, ND-6569 µg/kg) and 2-methylfuran (100%, 2-29639 µg/kg) were the compounds with the highest concentrations and detection rates in coffee products. The mean dietary exposure of Chinese consumers to furan and the sum of furan, 2-methylfuran and 3-methylfuran in coffee products was 0.09 and 0.46 µg/kg bw/day, respectively. For the neoplastic effects of furan, the margin of exposure (MOE) was 14,556 for the mean dietary exposure of consumers. For the non-neoplastic effects of furan, MOEs were 711 and 139 for furan and the sum of furan, 2-methylfuran and 3-methylfuran, respectively. Overall, a health concern is indicated for coffee consumers with MOEs below 10000.

BACKGROUND: Canaloplasty has been reported to manage primary open-angle glaucoma (POAG) effectively. However, no study has specifically and systematically investigated the efficacy and safety of canaloplasty for the treatment of POAG. Thus, this study will systematically and comprehensively appraise the efficacy and safety of canaloplasty for the treatment of POAG. METHODS: MEDLINE, EMBASE, Cochrane Library, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure will be sought from the construction to the February 29, 2020. Only randomized controlled trials (RCTs) focusing on canaloplasty for the treatment of POAG will be included. Two reviewers will independently undertake selection of study, data extraction, and risk of bias assessment. Any doubts between 2 reviewers will be resolved through discussion with another experienced reviewer. RevMan 5.3 software will be employed for data analysis. RESULTS: This study will summarize high-quality RCTs on investigating efficacy and safety of canaloplasty for the treatment of POAG. CONCLUSION: The findings of this study will help to determine whether canaloplasty is effective and safety for the treatment of POAG.Systematic review registration: INPLASY202040119.

BACKGROUND: Optic atrophy (OPA) is a very tricky disorder. Presently, no effective management is available for this condition. Previous studies have reported that acupuncture may be effective for the treatment of OPA. However, its effectiveness is still inconclusive. Thus, this study will aim to assess the effectiveness and safety of acupuncture for OPA. METHODS: A comprehensive literature search for relevant studies will be performed from the databases of PUMBED, EMBASE, CINAHI, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Cochrane Library, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, and other literature sources from inception up to the present. No language limitations will be applied to all literature searches. We will consider all randomized controlled trials (RCTs) and case-controlled trials (CCTs) for assessing the effectiveness and safety of acupuncture for OPA. The primary outcomes include the rates of vision improvement and visual field improvement. The secondary outcomes consist of the increased visual field average sensitivity, pattern visual evoked potential (PVEP) amplitude, and shortened PVEP latency, as well as any expected and unexpected adverse reactions. Risk of bias assessment will be performed by Cochrane risk of bias for RCTs and Newcastle-Ottawa Scale for CCTs. RESULTS: In this study, we will outline details of the aims and methods on the effectiveness and safety of acupuncture for the treatment of OPA. CONCLUSION: The results of this study will summarize the most current evidence of acupuncture for the treatment of patients with OPA. DISSEMINATION AND ETHICS: The results of this study are expected to be published on peer-reviewed journals. This is a literature-based study; therefore, no ethical approval is necessary.

BACKGROUND: Omega-3 and ranibizumab (O3R) has been reported to treat age-related macular degeneration (ARMD) effectively. However, up to the present, no systematic review specifically addressed the efficacy of O3R for the treatment of ARMD. Therefore, in this study, we will propose to assess the efficacy and safety of O3R for the treatment of ARMD. METHODS: We will search PUMBED, EMBASE, CINAHI, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Cochrane Library, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Information, Wanfang Data, as well as the gray literature from inception up to the present. We will accept randomized controlled trials for assessing the efficacy and safety of O3R for ARMD. The primary outcomes include change in best corrected visual acuity and central retinal thickness. The secondary outcomes consist of changes in subfoveal choroidal thickness, macular atrophy, retinal average sensitivity, contrast sensitivity, glare disability, and quality of life. In addition, incidence and severity of adverse events will also be evaluated. Cochrane Collaboration tool will be used to assess the risk of bias for each included study. In addition, Grading of Recommendations Assessment, Development, and Evaluation tool will be utilized to assess the overall strength of the evidence. Two authors will independently carry out all procedures and any divergences will be solved through discussion with a third author. If it is possible, we will conduct meta-analysis and subgroup analysis concerning different interventions, risk of bias, and outcome measurements. RESULTS: In this proposed study, we outline details of the aims and methods of efficacy and safety of O3R for the treatment of ARMD. CONCLUSION: The findings of this systematic review will summarize current evidence of O3R for the treatment of patients with ARMD. DISSEMINATION AND ETHICS: The results of the present study are expected to be published by peer-reviewed journals. This is a literature-based study. Thus, ethical approval is unnecessary for this study. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019121177.

OBJECTIVE: To explore regulatory mechanism of Ginkgo-dipyridamolum (GD) for calcium homeostasis on cardioprotective effect during ischemia reperfusion injury in the isolated rat heart. METHODS: 40 male SD-rats were randomly divided into five groups (n = 8): normal control group (NC), ischemia reperfusion group (IR), GD precondition group (GD + IR), Nicardipine and GD precondition group( Nic + GD + IR), and LaCl3 and GD precondition group (LaCl, + GD +IR). The hearts of rats were isolated after anesthesia and performed to profuse with Langendorff equipment. The heart functional indexes (HR, LVSP and ± dp/dt(max)) were detected at the five time points (stabilize point, ischemia 30 min, reperfusion 5 min, reperfusion 30 min, and reperfusion 60 min). The coronary effluents were also collected at the five time points. The activities of LDH and CK were measured, respectively, as well as the Ca2+ contents. After the experiments were finished,the myocardial mitochondria were isolated, homogenated and then the Ca2+ concentrations, the activities of IDH and α-OGDH were detected. The pathologic changes in myocardial tissues were also observed by histologic section. RESULTS: Compared with IR group, the heart functional indexes ( LVSP x HR and ± dp/dt(max)) of GD + IR group were improved at the five time points; the enzymes (LDH and CK) release, the Ca2+ concentrations, the activities of IDH and α-OGDH were reduced in mitochondrion. However, the protective effects above could be inhibited by Nic and LaCl3. Histologic sections showed that the myocardial tissue in IR group was damaged obviously, the damaged myocardial tissues were repaired in GD + IR, Nic + GD + IR and LaCl, + GD + IR) groups, especially in GD + IR group. CONCLUSION: Ginkgo-dipyridamolum can alleviate the myocardial ischemia reperfusion injury, the mechanism is probobaly related to maintaining calcium homeostasis and mitochondrial energy metabolism function.
