RESUMO

BACKGROUND: Viral pneumonia is a common respiratory disease that leads to high mortality around the world. Tanreqing (TRQ) injection has been widely used to treat viral pneumonia in China. However, the efficiency and safety of TRQ injection for viral pneumonia have not been scientifically and methodically evaluated up to now. Thus, this protocol describes a plan of performing a systematic review and meta-analysis to evaluate the efficacy and safety of TRQ injection on patients with viral pneumonia. METHODS: Only randomized controlled trials will be enrolled in our study, and we will search eligible studies in the following electronic databases: PubMed, Embase, Cochrane Central Register of Controlled Trials, Clinical Trials, China National Knowledge Infrastructure, the Wanfang database, the Chinese Scientific Journal Database, and the Sinomed. The total effective rate of clinical efficacy will be used as primary outcome. Time to relieve symptoms, incidence of adverse reactions, and the laboratory parameters will be used as secondary outcomes. Any side effects and adverse events will be recorded and assessed as safety outcomes. Study inclusion, data extraction, and quality assessment will be performed independently by 2 reviewers, and any disagreement will be resolved by a third reviewer. After that, data synthesis and subgroup analysis will be conducted with the Review Manager V.5.3.3 software. RESULTS: This review will provide a high-quality synthesis to assess the effectiveness and safety of TRQ injection for viral pneumonia patients. CONCLUSION: Our study will provide comprehensive evidence to decide whether TRQ injection is effective and safe for viral pneumonia patients. PROSPERO REGISTRATION NUMBER: PROSPERO CRD42020164164.

RESUMO

A Gram-stain-negative, strictly aerobic, non-flagellated, gliding, rod-shaped bacterium, designated C1T was isolated from the coastal sediment of Xiaoshi Island, Weihai, China. Phylogenetic analysis of the 16S rRNA gene and the genome sequence of the newly isolated strain revealed that it belonged to the genus Psychroflexus within the family Flavobacteriaceae. The 16S rRNA gene sequence similarities between strain C1T and the type strains of Psychroflexus members ranged from 91.6 to 94.9%. The AAI, POCP, ANI and dDDH values between strain C1T and Psychroflexus torquis ATCC 700755T were 67.0%, 53.1%, 70.5% and 20.2%, respectively. The DNA G+C content was 34.0 mol%. Strain C1T grows optimally at 28-30 â„ƒ, at pH 7.5-8.0 and with 3.0-5.0% (w/v) NaCl, and its colonies were orange-colored, convex and circular on the MA plate. Positive for hydrolysis of Tween 20 and catalase activities. The dominant respiratory quinone was menaquinone-6, and the major fatty acids were iso-C17:0 3-OH and iso-C15:0. The polar lipids of strain C1T consisted of phosphatidylethanolamine and three unidentified lipids. On the basis of phylogenetic, phenotypic and chemotaxonomic data, it is considered that strain C1T represents a novel species within the genus Psychroflexus, for which, the name Psychroflexus maritimus sp. nov., is proposed. The type strain is C1T (= MCCC 1H00415T = KCTC 72796T).

RESUMO

Endophytic fungi were isolated from Macleaya cordata growing in Dabie Mountain by agar-block method, and then the endophytic fungi were grouped into different types based on their morphological characteristics, and thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) were employed to determine whether the metabolic substances contained sanguinarine or not, and then preliminarily identified by morphological method. The results showed that the leaves hosted the largest number of endophytes (96 isolates) followed by the stems (57 isolates) and finally the roots (28 isolates), respectively. Based on morphological characteristics the endophytic fungi were grouped into 26 types in our study. TLC and HPLC results showed that there was sanguinarine in the metabolic substances of BLH 51 strain. According to the morphological characteristic, the BLH 51 strain was identified as Fusarium proliferatum. All these indicated that the medicinal plant M. cordata harbors abundant endophytes, which could be a new source for the search of active secondary metabolites.
