Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

【Objective】 To investigate the expression level of B7-H6 in peripheral blood and bone marrow of patient with chronic myeloid leukemia (CML), and to analyze its association with clinicopathological characteristics and prognosis. 【Methods】 A total of 120 CML patients from January 2010 to May 2013 were selected as study subjects. The expression of B7-H6 mRNA in CML peripheral blood and bone marrow pre- and 3-, 6-, 12-month-posttreatment was detected by quantitative real time PCR, and its correlation between prognosis and clinicopathological factors was analyzed. 【Results】 The expression level of B7-H6 mRNA in the PB, BMMCs of CML patients was lower than that of the normal population (P<0.05). B7-H6 mRNA in PB at 3-, 6-, 12-month-posttreatment increased as compared with that of pre-treatment (P < 0.05). As treatment time prolonged, the expression level of B7-H6 mRNA increased gradually (P < 0.05). B7-H6 levels in BM samples from CML with BCR-ABL1/ABL≤0.1%, CCR were significantly higher than that in patients with BCR-ABL1/ABL>0.1%(P<0.0001) or without CCR (P<0.001). The expression level of B7-H6 in BMMCs was negatively correlated with the BCR-ABL1/ABL level (r=–0.260, P<0.05). Signifiant difference in PFS was observed between patients with high expression level of B7-H6 (not reached, HR: 0.06, 95% CI =0.03-0.37) and low expression level (81 months, HR: 15.58, 95% CI =2.68-30.23) in BM (P<0.05). 【Conclusion】 The low expression of the B7-H6 gene in CML is correlated with BCR-ABL1 copy number and responsiveness to treatment, and monitoring of B7-H6 expression may be used to evaluate CML prognosis, progression and treatment efficacy.

Objective To explore the genetic mechanism of Yang-deficiency constitution by detecting genomic copy number variations (CNVs). Methods Thirty cases of Yang-deficiency constitution and 30 cases of balanced constitution were included according to the standards of Classification and Determination of Constitution in Traditional Chinese Medicine. DNA was extracted from white blood cells in peripheral blood. A genome-wide association study was conducted by using Affymetrix SNP 6.0 platform. CNVs of each sample were analyzed using PennyCNV software. The Yang-deficiency constitution-specific copy number variation regions (CNVRs) of each autosome were identified. CNVR-related genes and their annotations were searched at online Human Genome Browser. Results The mean number of CNVs in balanced constitution group was 12.63±3.39, ranging from 8 to 20. After stepwise elimination of two Yang-deficiency constitution subjects, the mean number of CNVs in Yang-deficiency constitution group was 15.04±8.95, ranging from 2 to 38. A total of 26 CNVRs were identified from 28 Yang-deficiency constitution subjects, including 19 duplicated CNVRs, 6 deleted CNVRs, and 1 mixed type CNVR. Most CNVRs were shared by a few Yang-deficiency constitution subjects, and only 7 CNVRs were shared by more than 5 Yang-deficiency constitution subjects. The functions of representative genes in Yang-deficiency constitution-specific CNVRs were related with extracellular and intracellular signal transduction, metabolic regulation, and immune response, etc. Conclusion Yang-deficiency constitution subjects have some specific genomic CNVs, which might result in Yang-deficiency constitution phenotypes by influencing the expression of genes associated with extracellular and intracellular signal transduction, material metabolism (energy metabolism), and immune response, etc.

Objective To summarize the clinical experiences in liver transplantation from donation after cardiac death donors. Methods The clinical data of 20 recipients who underwent liver transplantation from donation after cardiac death of 20 donors at the Guangzhou General Hospital of Guangzhou Military Area from July 2006 to May 2011 were retrospectively analyzed.Extracorporeal membrane oxygenation (ECMO) was applied to donors with brain and cardiac death to avoid warm ischemia.Donors in type Ⅲ according to the Maastricht classification did not receive ECMO.Liver grafts were obtained 5 minutes after the stop of heartbeat of the donors.Orthotopic liver transplantation was performed on recipients.Seventeen recipients received end-to-end bile duct anastomosis and 3 received cholangioenterostomy.All the recipients were followed up regularly.The survival curve was drawn by Kaplan-Meier method.Results Of the 20 donors,2 ( 10％ ) were in the type of Maastricht Ⅲ and 18 (90％) were donation after brain and cardiac death donors.Liver transplantation was successfully performed on all recipients,and the mean operation time,duration of anhepatic phase,mean volume of blood loss and duration of postoperative intensive care unit stay were (6.2 ± 2.7 ) hours,( 54 ± 13 ) minutes,( 2305 ± 1311 ) ml and (44 ±35) hours,respectively.There was no mortality during operation,and no recovering delay and non-function of the transplanted liver occurred.One recipient died of sepsis and 1 died of pulmonary infection at 1 month after operation,the other 18 recipients all survived.The longest survival time was 58 months.Conclusions Donation after cardiac death is the main source of liver grafts in China currently,and donation after brain and cardiac death is the main type.Establishment of rational flow-sheets of the donation after cardiac death and liver transplantation,rational application of ECMO for protecting the liver grafts are helpful for the work of organ donation after brain and cardiac death.
