Purpose – To purpose of this study is to describe and to demonstrate the value of a consortium purchase of the ProQuest Dissertations and Theses full-text database (PQDT) in China. Design/methodology/approach – The authors provide a first-person account based on their professional positions at the China Academic Library & Information System Administrative Center. Findings – That the PQDT database has steadily increased the use of theses in China with more institutions subscribing every year. The PQDT full-text database has become one of the most cost effective databases cooperatively purchased in China. Originality/value – One of the few in-depth studies of the use of the PQDT database.

IntroductionMild cognitive impairment (MCI) is considered the intermediate phase between normal age-related cognitive decline and dementia. Moxibustion has gained increased popularity for the management of MCI in China.This study aimed to evaluate the effects and safety of moxibustion on symptoms of MCI.Methods and analysisFour English databases and six Chinese databases will be searched from their inception to October 2019: Embase, MEDLINE, Cochrane Central Register of Controlled Trials, Allied and Complementary Medicine Database, China National Knowledge Infrastructure, Chongqing VIP Chinese Science and Technology Periodical Database, Wanfang Database, SinoMed, China Doctoral Dissertations Full-text Database and the China Master’s Theses Full-text Database. Only clinical randomised controlled trials and the first period in randomised cross-over trial related to moxibustion for MCI will be included. The primary outcomes include the improvement of cognitive function, as measured by validated assessment tools. The secondary outcomes include changes in the activity of daily living scale, effective rate and the incidences of adverse events. The selection of studies, data extraction and risk of bias assessment will be carried out by two independent reviewers. Review Manager V.5.3 software will be used for statistical analyses. Heterogeneity test, data synthesis and subgroup analysis will be performed if necessary. The risk of bias of included studies will be assessed by theCochrane Handbookrisk of bias tool. Evidence quality will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation system.Ethics and disseminationEthics approval is not required as no private information from individuals are collected. The results will be published in a peer-reviewed journal or disseminated in relevant conferences.Trial registration numberCRD42018112657.

Objective: The aim of this study was to use the Animals in Research: Reporting In Vivo Experiments (ARRIVE) guidelines to evaluate the quality of reporting of recent gastric cancer animal experiments. Materials and Methods: A literature search of studies was performed using the Chinese Biomedical Literature Database, Chinese Journal Full-text Database, Chinese Scientific Journal Full-text Database, and Wanfang Database from January 2010 to December 2012. We extracted data using pre-prepared Excel data-extraction forms. Reporting quality was evaluated based on the ARRIVE guidelines. Results: Of the 1816 studies that were identified by our search, 170 were subjected to quantitative analysis using the ARRIVE guidelines. The results of the evaluation based on the ARRIVE guidelines were that 132 studies (77.61%) provided an accurate and concise description of baseline conditions and clinical conditions. Only 2 (1.18%) papers provided relevant certificates of ethical review or institutional guidelines, and 2 (1.18%) papers provided an explanation of animal experiments requiring algorithms and formulas for sample size. Forty-seven (27.65%) studies described in detail how animals were assigned to each experimental group, including the randomization procedure, 2 (1.18%) reported whether blinding was used, and 15 (8.82%) evaluated the limitations of the study. Conclusions: The reporting quality of recent animal experiments of gastric cancer is inadequate. We should improve not only the quality of the methodology but also the reporting quality of the animal experiments.

Abstract Object:To explore the correlation between serum vitamin D level and the occurrence and pathological grade of gastric cancer.Data sources:Search the PubMed, Embase, Web of Science, Cochrane,Chinese Journal Full-text Database (CNKI), Wanfang Science and Technology Journal Full-text Database, Chinese Science and Technology Journal Full-text Database (VIP), Chinese Biomedical Literature Database (CBM), All articles about the correlation between serum vitamin D levels and gastric cancer published before July 2021.Results:10 trials with 1159 cases of gastric cancer patients and 33387 cases of normal control patients were analyzed. The serum vitamin D level of the gastric cancer group(15.56±7.46ng/ml) was lower than the control group (17.60±1.61ng/ml), and the difference was statistically significant (MD=-8.28, 95%CI: -14.32~-2.23, P <0.00001). The patients with gastric cancer clinical stage III/IV(16.19±8.04ng/ml) is lower than that of patients with stage I/II (19.61±9.61ng/ml), and the patients with low differentiation of gastric cancer is (17.5± 9.5ng/ml) is lower than that of well or moderately differentiated patients (18.04±7.92ng/ml), and the patients with lymph node metastasis (19.41±8.63ng/ml) is lower than that of patients without lymph node metastasis (20.65± 7.96ng/ml), the difference is statistically significant;Conclusions:Vitamin D levels are negatively correlated with the occurrence of gastric cancer. Vitamin D levels are significantly correlated with different clinical stages, degrees of differentiation and lymph node metastasis, suggesting that low vitamin D levels may be a predictor of poor prognosis in gastric cancer.
