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 application of three-dimensional visualization in interventional treatment of Budd-Chiari syndrome (BCS) with the hepatic vein occlusion type.Methods A retrospective study was conducted on 15 patients with BCS of the hepatic vein occlusion type who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2017 to June 2018.The study included 8 males and 7 females with a mean age of (36.7±14.4) years.All patients were examined with MRI enhanced scanning and the original MRI data of the DICOM format were extracted.The digital data were then extracted and reconstructed by the Mimics software to obtain a three-dimensional visualization model.The hepatic vein was recanalized under the guidance of the three-dimensional visualization model.Results The three-dimensional visualization model was successfully constructed.Of all the 15 three-dimensional visualization models,right hepatic vein ostial stenosis occurred in 4 patients and occlusion in 11 patients.The middle hepatic vein and the left hepatic vein formed a common trunk in 15 patients,and ostial stenosis and occlusion of the common trunk occurred in 3 and 12 patients,respectively.Communicating branches between the right and middle hepatic veins occurred in 6 patients.Accessory hepatic veins occurred in 3 of 15 patients,and the accessory hepatic vein ostium was stenosed in 3 patients.Communicating branches between the accessory hepatic vein and the right hepatic vein occurred in 2 patients,and communicating branches between the accessory hepatic vein and the middle hepatic vein occurred in 1 patient.All patients were treated successfully with interventional treatment without any complications.One,2,and 3 hepatic veins were recanalized in 7,5 and 3 patients,respectively.Conclusion The three-dimensional visualization was valuable in displaying the location,pattern and collateral vessels of the hepatic veins in BCS patients with the hepatic vein occlusion type.It was helpful for accurate preoperative assessment and to make individualized interventional treatment plans.

Ohjective To evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of sinusoidal obstruction syndrome (SOS) caused by gynura segetum.Methods The clinical data of 9 patients with SOS caused by gynura segetum (5 males and 4 females) who underwent TIPS were retrospectively analyzed from February 2017 to June 2018.The Child-Pugh scores were (9.5 ± 1.3) and the MELD scores were (12.5 ± 5.0).The success rates,complications and follow-up results were evaluated.Results TIPS was performed successfully in all the 9 patients.The portal venous pressure gradient dropped from (22.4 ± 2.7) mmHg to (10.4 ± 3.2) mmHg (P ＜ 0.05).There was no complication such as abdominal hemorrhage and biliary peritonitis.Nine patients were followed-up for 1 ～17months,mean 7.8 ± 6.0 months.One month after treatment,the Child-Pugh scores were (7.1 ± 1.8),compared with that of the preoperative scores,the difference was statistically significant (P ＜ 0.05).The MELD scores were (5.3 ± 4.6),compared with that of the preoperative scores,the difference was also statistically significant (P ＜ 0.05).At the end point of the follow-up,color Doppler ultrasound and portal CTA showed that the TIPS shunt was patent and hepatic congestion was relieved in all the 9 patients.All patients were alive.Conclusion TIPS was a safe and efficacious treatment for SOS caused by gynura segetum.

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.
