Objective To compare the efficacies of allogeneic hematopoietic stem cell transplantation(allo-HSCT)in the treatment of post-chronic aplastic anemia(CAA)myelodysplastic syndrome(MDS)and primary MDS.Methods A retrospective analysis was conducted on 32 patients who received allo-HSCT treatment in Department of Hematology,North China University of Science and Technology Affiliated Hospital between Feb.2012 and Feb.2022,including 12 patients with post-CAA MDS and 20 patients with primary MDS.The overall survival rate,cumulative incidence of relapse(CIR)rate,non-relapse mortality(NRM)rate,and event-free survival rate were compared between the 2 groups.Results The median follow-up time for CAA to progress to MDS was 120(72-180)months.All the patients were followed up for 36(3-79)months after allo-HSCT.The 3-year overall survival rate of the post-CAA MDS group was significantly higher than that of the primary MDS group(83.8%vs 45.0%,P=0.035).The 3-year CIR of the post-CAA MDS group was significantly lower than that of the primary MDS group(16.7%vs 55.0%,P=0.021).There was no significant difference in the event-free survival rates or NRM rates between the 2 groups(both P＞0.05).Conclusion The post-CAA MDS patients have better survival after allo-HSCT than the primary MDS patients.Early allo-HSCT treatment may improve the prognosis.

Based on the Delphi method, this study conducted an expert questionnaire survey on the diagnostic criteria of edema in TCM by integrating preliminary literature research, aiming to further standardize the revision of Edema diagnosis in Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine (ZY/T001.1－94). Relevant literature on TCM edema was comprehensively retrieved from CNKI, Wanfang Data, VIP and CBM from 1994 to July 1, 2021. The content extracted from the literature was integrated with the diagnostic criteria outlined in the 1994 Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine to establish the questionnaire item pool; two rounds of Delphi expert surveys were conducted to identify content requiring revisions. Subsequently, the degree of concentration and coordination of the expert opinions were analyzed to determine items for inclusion in the revised draft. Ultimately, the finalized revised diagnostic criteria for edema were developed through expert panel discussions. Results showed expert participation rates of 84.21% and 78.13% in respective survey rounds. The progressive increase in Kendall's coefficient of concordance (Kendall's W=0.169 in Round 1 to Kendall's W=0.368 in Round 2) quantitatively validated enhanced expert consensus (both the degree of concentration and coordination) and systematic alignment of revision proposals for diagnostic items. The study findings demonstrated an urgent need for improving the diagnostic criteria section of the the 1994 Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine, and the proposed revisions would be expected to enhance the applicability and specificity of edema diagnostic standards in clinical practice.

Objective:Applying bibliometrics to analyze the research history, hotspots and trends of Traditional Chinese Medicine (TCM) interventions in edema-related diseases, and to provide reference for the revision of diagnostic and therapeutic criteria for edema in TCM.Methods:The literature about edema treated with TCM was retrieved from CNKI, Wanfang, VIP, CBM from 1 st. Jan 1995 to 25 th. May 2022. CiteSpace and VOSviewer softwares were used to draw the knowledge map, and analyze the co-occurrence relationship and clustering characteristics of the institution, author, keywords and mechanism hotspots. Results:Totally 3 198 articles were included. The annual number of documents issued generally shows a spiral rise trend. Liaoning University of Chinese Medicine published the most articles. Core authors published the most articles were Sun Wei (13 articles); the team with the highest cooperation intensity was Yang Hongtao's team; keywords formed 7 clusters. Hotspot mechanisms included metabolic disorders, immune balance, anti-inflammation, calcium and phosphorus metabolism. Keywords in the past 7 years were membranous nephropathy, chronic heart failure, diabetes, lymphedema etc.Conclusions:The attention paid to the intervention of TCM in the field of edema is generally on the rise, and has decreased in the past two years. The research categories focus on the experience of famous doctors, clinical trials, and mechanistic studies, and nephropathy-related edema has been the focus of research; diabetic nephropathy, chronic heart failure, metabolomics, and immunotherapy are expected to be the focus of attention in the next stage.

Objective:To analyze the efficacy evaluation criteria of the existing TCM treatment for edema RCT research, and to provide reference for the construction of unified standards.Methods:The batabases CNKI, WanFang Data, VIP, CBM, Pubmed and Web of Science were retrieved. The randomized controlled trials for the treatment of edema of TCM research, from September 1, 1993 to July 31, 2022, were screened and included. The content of efficacy evaluation, performed statistics on evaluation standard, the curative effect evaluation indexes, as well as standard composition, usage were extracted. We analyzed the characteristics, application and problems of the existing efficacy evaluation criterion.Results:A total of 123 Chinese articles were included. The included literature involved nephrogenic edema, cardiogenic edema, idiopathic edema, apoplexy limb edema and other edema. In recent years, randomized controlled trials on the treatment of edema by TCM have mainly used four efficacy evaluation criteria. Of which the Guidelines for Clinical Research on New Chinese Medicines (Trial) in 2002 had the highest utilization rate of 29.27%. Secondly, the utilization rate of Standard for Diagnosis and Curative Effect of TCM Diseases and Syndromes was 21.14%. The rest of the criteria were used by less than 6%. While 39.02% of the literature did not use the standards or used self-designed standards. Among the composition of efficacy evaluation indices, the application rate of TCM syndrome or symptom efficacy index was the highest (91.87%), the utilization rate of the Minnesota Living with Heart Failure Questionnaire Indicators was only 4.88%; biochemical tests accounted for a large proportion of Western medical indicators, while the measurement of edema severity was rarely applied. Conclusions:At present, the evaluation criteria of edema curative effect are diversified and insufficiently popularized, which need to be further screened and improved. It is suggested to construct a TCM edema efficacy evaluation model based on the characteristics of edema syndrome, comprehensively evaluate the efficacy from multiple dimensions such as TCM syndromes, western medicine indicators, and quality of life, and improve the scientific indicators.

Objective To explore the specific plasma exosomal protein expression in Coronary Heart Disease(CHD)with phlegm-turbidity syndrome(PTS),so as to provide biological reference for the diagnosis of CHD with PTS.Methods A total of 20 CHD patients with PTS and 20 healthy subjects at the same period were included.Plasma exosomes were extracted from all subjects using the qEV size exclusion method.First,10 CHD cases with PTS and 10 healthy subjects were randomly selected,and differentially expressed proteins between the two groups were screened using label free non-targeted protein quantification analysis.Then,MRM targeting protein labeling technique was applied to verify the differentially expressed proteins in the remaining subjects.Results Compared with healthy controls,214 differentially expressed plasma exosomal proteins(61 up-regulated and 153 down-regulated)were found in CHD patients with PTS,mainly related to cholesterol metabolism,complement and coagulation cascade,and immune effects.ANXA6,C4BPB,F8,CFB,APOE,C9,and CLU proteins were further validated by MRM targeting protein.Conclusion CHD patients with PTS had differences in plasma exosomal protein expression from healthy controls,and the differential proteins are mainly related to cholesterol metabolism,complement,and the coagulation cascade.

Objective To observe the effect of Baduanjin on mild cognitive impairment (MCI). Methods From January to June, 2016, 60 patients with MCI in community were randomly divided into control group (n=30) and training group (n=30). The training group accepted training of Baduanjin for six months, and the control group accepted no intervention. They were assessed with Montreal Cognitive Assessment (MoCA) before and after intervention; while the blood lipid, and serum interleukin-6 (IL-6), acetylcholine (Ach), superoxide dismutase (SOD) and malondialdehyde (MDA) were detected. Results The total score, and scores of visual space and executive function, abstract and delayed memory of MoCA were more in the training group than in the control group after intervention (t>3.576, P<0.01), while the level of total cholesterol, IL-6 and MDA decreased (t>2.744, P<0.05), and the level of high density lipoprotein cholesterol, Ach and SOD increased (t>2.922, P<0.01). Conclusion Baduanjin can improve the cognitive function in MCI patients, as well as reducing blood fat, oxidation and inflammation. There may be some relationship between them.

OBJECTIVETo delineate the clinical features and potential mutation of the ATP7A gene in a family affected with Menkes disease.

METHODSClinical data of a patient and his family members were analyzed. Sanger sequencing and multiplex ligation-dependent probe amplification (MLPA) assays were performed to detect the mutation of the ATP7A gene.

RESULTSThe patient was admitted at the age of 5 months due to severe epilepsy and marked delayed psychomotor development. Significantly light complexion, pudgy cheeks and sparse fuzzy wooly hair were noted. Cranial magnetic resonance imaging and angiography revealed cortical atrophy, leukoencephalopathy and circuitous of intracranial vessels. The plasma ceruloplasmin was decreased. MLPA has identified a deletion spanning exons 8 to 12 of the ATP7A gene. His mother was found to be a heterozygous carrier of the same mutation.
