Aims and Scope

The Chinese Journal of Endocrinology and Metabolism (CJEM) was established in July 1985. It is an advanced academic journal sponsored by the Chinese Medical Association (CMA) reporting recent studies in the field of endocrinology and metabolism in China. It is dedicated to becoming the Chinese journal introducing the latest developments in international endocrinology and metabolism research.

The target readership of this journal mainly includes endocrinologists and physicians. In the more than 30 years of its development, CJEM has aimed to increase the standard of diagnosis and treatment as well as the clinical management of endocrine and metabolic disorders in China by pursuing advances and targeting hotspots, as well as prudent manuscript solicitation; reporting the latest research outcomes and clinical treatments in endocrinology and metabolism and other relevant fields, as well as basic theoretical research that guides and closely integrates clinical works in endocrinology and metabolism; initiating “Special Editorial”, inviting experts across different fields to share their insights on medical development while also extending invitations to foreign researchers to contribute and deliberate on their academic viewpoints; initiating “Selects from Foreign Journals”, translating and compiling the latest developments in the international endocrinology and metabolism field upon acquiring the copyright of the original publication; initiating a special column, “Youth Forum”, to create a platform to inspire outstanding young and middle-aged academics and increase the overall standard in the field of endocrinology and metabolism. This journal also includes columns on clinical and basic research, seminars, approach to the patients, continuing medical education for management of endocrine disorders (Endocare CME) and others. It is also actively working on the new media construction, setting up a WeChat public account and a journal app to provide readers and authors with a new reading experience.

 The Chinese Journal of Endocrinology and Metabolism has received the award for “Outstanding Chinese Scientific Journal” from the China Association for Science and Technology in 2008, 2011, 2014 and 2017.

If the author disagrees with the manuscript review outcome, he/she may send in a written appeal. For detail introduction of the review process, please read the separate introduction.

Manuscript processing time

In accordance with the “Copyright Law of the People’s Republic of China” and based on the actual circumstance of the journal, if the author has not received any notice within 3 months of issue of receipt acknowledgment of the manuscript, the manuscript is deemed to be under review. If the author wishes to submit the manuscript to another publisher, he/she must inform the Editorial Office in advance; otherwise, this will be deemed as duplicate submission and the manuscript will be rejected.
