Currently, due to many high-profiled benefits, clinical studies on Toujie Quwen granule (TJQW) have been increasing. The aim of the study is to assess the efficacy and safety of TJQW used with conventional western therapy for COVID-19.Methods:Relevant randomized controlled trials (RCTs) were searched in Chinese and English databases, and the search time is January 2020 to May 2021. English databases include PubMed, Embase, Web of Science, and the Cochrane Library. Chinese databases include CNKI, WF, VIP, and CBM. The international clinical trial registration platform and the Chinese clinical trial registration platform of controlled trials will be searched by us from January 2020 to May 2021. According to the inclusion and exclusion criteria, screening literature, extraction data will be conducted by 2 researchers independently. Statistical analysis will be conducted using the RevMan 5.3.5 software. After screening the literature based on the inclusion and exclusion criteria, The Recommendation, Assessment, Development, and Evaluation (GRADE) system will be used to evaluate the quality of each result.Results:This study will provide the evidence for TJQW to be used with conventional western therapy for COVID-19.Conclusion:The efficacy and safety of TJQW used with conventional western therapy for COVID-19 will be assessed.INPLASY registration number:INPLASY202150038

Expression of reg protein in rat regenerating islets and its co-localization with insulin in the Beta cell secretory granules

Summary Regenerating islets can be induced by the administration of poly(ADP-ribose) synthetase inhibitors to 90% depancreatized rats. In screening a regenerating isletderived cDNA library, we previously isolated a novel gene, reg (regenerating gene), which encodes a 165-amino acid protein with a 21-amino acid signal sequence. In the present study, we have examined the expression and localization of reg protein in the regenerating islets by immunocytochemical techniques using a monoclonal antibody against a recombinant rat reg protein of 144 amino acids without the signal sequence. Light microscopy examination showed strong immunoreactivity for reg protein in the regenerating islets of the rats at two weeks and two months after the 90% pancreatectomy, whereas reg protein was almost undetectable in normal rat islets or in the islets of the rats one year after the pancreatectomy. Almost all the reg protein-positive cells were stained for insulin. By applying the immunogold technique at the ultrastructural level, it was demonstrated that both reg protein and insulin occur in the central granular core of the regenerating Beta cell secretory granules. These results suggest that reg protein is synthesized in and secreted from the regenerating Beta cells and that its expression is closely associated with Beta-cell regeneration.
