Objective: To evaluate the methodological quality and reporting quality of clinical practice guidelines or expert consensus on blood transfusion and blood use (BTBU) in China (hereinafter referred to as "guidelines/consensus"), providing reference for the development and updating of future BTBU guidelines/consensus. Methods: A systematic search was conducted in Chinese databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Data-base, relevant guideline release platforms, and professional association websites. BTBU-related guidelines/consensus published between January 2006 and December 2025 were included. According to the inclusion and exclusion criteria, after completing literature screening and data extraction, three evaluators independently assessed the quality of the included literature using the Scientificity, Transparency, and Applicability of Guidelines Rating Tool (STAR), the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), and the International Practice Guideline Reporting Standards (RIGHT). Results: A total of 29 documents were included, including 5 guidelines, 22 consensus statements, and 2 protocols. The results of the STAR assessment showed that the total score was (21.7±8.8)%. The domain score ratios for registration, research protocol, funding, working group, conflict of interest, clinical question, evidence, consensus method, recommendation, accessibility and other domains were (2.2±12.1)%, 0, (36.7±25.1)%, (18.3±7.6)%, (19.2±15.3)%, (16.6±23.1)%, (15.1±6.3)%, (9.6±21.2)%, (54.3±18.4)%, (31.7±10.4)% and (10.3±31.0)%, respectively. For the AGREE Ⅱ assessment, the methodological quality of 26 articles was rated Grade B and 3 articles Grade C. The results of the RIGHT assessment indicated that the overall reporting rate of all guidelines/consensuses was (65.3±4.0)%. Conclusion: The methodological and reporting quality of current expert guidelines/consensus on BTBU in China still need improvement, and guidelines and consensus should be strictly formulated and standardized according to the standards of STAR, AGREE II and RIGHT.

Chloasma is a common pigmentation on facial skin among middle-aged or young women. The characteris-tic of chloasma is acquired brown spots on exposed facial regions. Modern traditional Chinese medicine (TCM) clini-cal treatment mostly follows syndrome differentiation and treatment as well as prescriptions of TCM doctors from pre-vious dynasties. On the basis of different facial location of chloasma, the author explored the correlation between the facial lesion location and five zang-organ under the guidance of TCM holism concept. The creativeness of combining division differentiation and channel pattern differentiation, and the application of channel tropism medicine, provide new ideas for chloasma treatment.

Traditional Chinese medicine (TCM) diagnostic methods contain inspection, auscultation-olfaction, inter-rogation and palpation. The clinical doctor collects information through the four diagnostic methods. Various symp-toms of the disease are especially used as the main evidence to determine different diseases and to identify the syndrome. Therefore, the TCM four diagnostic methods are the basic means of disease understanding in TCM. This article collected and analyzed clinical data in order to summarize the unique features and focused aspects of TCM four diagnostic methods application on TCM surgery and dermatology. This article was aimed to provide new ideas for TCM four diagnostic methods in the clinical diagnosis of dermatological diseases.
