Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Microwave thermotherapy(MWTT),as a treatment for tumors,lacks specificity and requires sensitizers.Most reported microwave sensitizers are single metal-organic frameworks(MOFs),which must be loaded with ionic liquids to enhance the performance in MWTT.Meanwhile,MWTT is rarely combined with other treatment modalities.Here,we synthesized a novel Fe-Cu bimetallic organic framework FeCuMOF(FCM)by applying a hydrothermal method and further modified it with methyl polyethylene glycol(mPEG).The obtained FCM@PEG(FCMP)showed remarkable heating performance under low-power microwave irradiation;it also acted as a novel nanospheres enzyme to catalyze H2O2 decompo-sition,producing abundant reactive oxygen species(ROS)to deplete glutathione(GSH)and prevent ROS clearance from tumor cells during chemodynamic treatment.The FCMP was biodegradable and demonstrated excellent biocompatibility,allowing it to be readily metabolized without causing toxic effects.Finally,it was shown to act as a suitable agent for T2 magnetic resonance imaging(MRI)in vitro and in vivo.This new bimetallic nanostructure could successfully realize two tumor treatment modalities(MWTTand chemodynamic therapy)and dual imaging modes(T2 MRI and microwave thermal imaging).Our findings represent a breakthrough for integrating the diagnosis and treatment of tumors and pro-vides a reference for developing new microwave sensitizers.

This study aims to explore the effect of tryptanthrin on potential metabolic biomarkers in the serum of mice with ulcerative colitis(UC) induced by dextran sulfate sodium(DSS) based on liquid chromatography-mass spectrometry(LC-MS) and predict the related metabolic pathways. C57BL/6 mice were randomly assigned into a tryptanthrin group, a sulfasalazine group, a control group, and a model group. The mouse model of UC was established by free drinking of 3% DSS solution for 11 days, and corresponding drugs were adminsitrated at the same time. The signs of mice were observed and the disease activity index(DAI) score was recorded from the first day. Colon tissue samples were collected after the experiment and observed by hematoxylin-eosin(HE) staining. The levels of interleukin-4(IL-4), interleukin-10(IL-10), tumor necrosis factor-α(TNF-α), interleukin-6(IL-6), and interleukin-8(IL-8) in the serum were measured by enzyme linked immunosorbent assay(ELISA). The serum samples were collected from 6 mice in each group for widely targeted metabolomics. The metabolic pathways were enriched by MetaboAnalyst 5.0. The results showed that compared with the model group, tryptanthrin treatment decreased the DAI score(P<0.05), alleviated the injury of the colon tissue and the infiltration of inflammatory cells, lowered the levels of proinflammatory cytokines, and elevated the levels of anti-inflammatory cytokines in the serum. The metabolomic analysis revealed 28 differential metabolites which were involved in 3 metabolic pathways including purine metabolism, arachidonic acid metabolism, and tryptophan metabolism. Tryptanthrin may restore the metabolism of the mice with UC induced by DSS to the normal level by regulating the purine metabolism, arachidonic acid metabolism, and tryptophan metabolism. This study employed metabolomics to analyze the mechanism of tryptanthrin in the treatment of UC, providing an experimental basis for the utilization and development of tryptanthrin.

Dead heart is an important trait of pith-decayed Scutellariae Radix. The purpose of this study was to clarify the scientific connotation of the dead heart using multi-omics. Metabolomics and transcriptomics combined with multivariate statistical analysis such as principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA) were used to systematically compare the differences in chemical composition and gene expression among phloem, outer xylem and near-dead xylem of pith-decayed Scutella-riae Radix. The results revealed significant differences in the contents of flavonoid glycosides and aglycones among the three parts. Compared with phloem and outer xylem, near-dead xylem had markedly lowered content of flavonoid glycosides(including baicalin, norwogonin-7-O-β-D-glucuronide, oroxylin A-7-O-β-D-glucuronide, and wogonoside) while markedly increased content of aglycones(including 3,5,7,2',6'-pentahydroxy dihydroflavone, baicalin, wogonin, and oroxylin A). The differentially expressed genes were mainly concentrated in KEGG pathways such as phenylpropanoid metabolism, flavonoid biosynthesis, ABC transporter, and plant MAPK signal transduction pathway. This study systematically elucidated the material basis of the dead heart of pith-decayed Scutellariae Radix with multiple growing years. Specifically, the content of flavonoid aglycones was significantly increased in the near-dead xylem, and the gene expression of metabolic pathways such as flavonoid glycoside hydrolysis, interxylary cork development and programmed apoptosis was significantly up-regulated. This study provided a theoretical basis for guiding the high-quality production of pith-decayed Scutellariae Radix.

【Objective:】 To understand the current situation of nurses’ professional quality of life in China and its correlation with benefit findings, so as to provide reference for formulating targeted measures to improve nurses’ professional quality of life in China. 【Methods:】 Questionnaire star was used to conduct a cross-sectional survey of 11 924 registered nurses in China from January 2022 to April 2022 using the General Information Questionnaire, the Professional Quality of Life Scale (ProQOL) and the General Benefit Discovery Scale (GBFS). SPSS 22.0 software was used for data analysis. 【Results:】 The scores of various dimensions of nurses’ ProQOL scale were: compassion satisfaction was (32.71±6.81) points, burnout was (27.38±5.20) points, secondary traumatic stress was (28.44±6.67) points, and the total score of GBFS was (100.90±18.04) points. The results of multiple linear stepwise regression showed that the main influencing factors of compassion satisfaction were marital status, position, work unit level and educational background (P<0.05). The main influencing factors of burnout were position, professional title, work unit level and whether there were children to be taken care of at home (P<0.05). The main influencing factors of secondary traumatic stress were education background, marital status, professional title, whether there was an old person to be taken care of at home, whether to take care of COVID-19 patients, whether to be an epidemic support staff and position (P<0.05). Benefit finding independently predicted the three dimensions of nurses’ professional quality of life (P<0.001). 【Conclusions:】 Chinese nurses’ professional quality of life was at a moderate level and it was significantly affected by benefit finding. Attention should be paid to factors such as marital status, work unit level, position, professional title, education background, whether there was an old person to be taken care of at home, whether to take care of COVID-19 patients, so as to improve the level of nurses’ benefit finding, promote their personal growth, provide good job guarantee, and improve Chinese nurses’ professional quality of life.

"Healthy China 2030" states that health is a necessary requirement for all-round human development and a basic condition for economic and social development. Achieving national health and longevity is an important symbol of national prosperity and rejuvenation, and also the common aspiration of the people of all ethnic groups in China. Traditional Chinese medicine (TCM) health preservation has been fully integrated into the construction of "Healthy China", and the development of TCM health preservation culture and thought has a profound historical origin. Starting from the development of TCM health preservation culture thought and ethical principles, this paper analyzed the TCM health preservation thought contained in Master Lyu’s Spring and Autumn Annals, and further discussed and summarized the ethical principles contained in them, with a view to comprehensively and systematically promoting the development of TCM health preservation culture and providing a theoretical basis for people to use health preservation ethical principles to achieve physical fitness, disease prevention and longevity.

Asiatic acid (AA) is a ursane pentacyclic triterpenoids, which possesses a wide range of pharmacological activities, such as anti-tumor, hypoglycemic, anti-inflammatory, anti-bacterial. Due to poor solubility and low bioavailability, clinical application of asiatic acid is limited. To address these defects, the structural modifications of AA have been carried out, and large numbers of AA-based derivatives with novel structure and eximious biological activity have been developed. In this paper, the research progress of structural modifications, biological activity, structure-activity relationship and mechanism studies in recent twenty years are reviewed, which provides reference for development of AA-related drugs.

Objective To analyze the basic characteristics, drug features, prescription rules, and drug-symptom relationships of patients in the splenic deficiency and impairment stage, by data mining of medical records under the New Theory on Spleen Dampness Syndrome (Pi Dan Xin Lun, 《脾瘅新论》). Methods Medical records listed in the “New Theory on Spleen Dampness Syndrome – Understanding and Treatment of Metabolic Syndrome from the Perspective of Traditional Chinese Medicine”, and which were diagnosed with the spleen dampness syndrome at the splenic deficiency and impairment stage, during January 2004 and December 2016 were selected. These patients’ data, including basic information, clinical symptoms, laboratory examination results, traditional Chinese medicine (TCM) and western medicine diagnoses, treatment methods, prescriptions, etc., were collected. The collected data were subsequently compiled into a medical record database using the Epidata 3.1 data management software, followed by the use of Apriori algorithm provided in the SPSS Modeler 14.2 statistical software to investigate the association rules between drug-drug, drug-symptom, and drug-western medicine indices. Results (i) A total of 51 medical records were included, involving 17 types of syndromes. Among them, the top three with frequency ≥ 3 included “Phlegm and blood stasis, and thoracic obstruction” “Deficiency-weakness of the spleen Qi, and static blood blocking collaterals”, and “Deficiency-weakness of the spleen Qi, and static blood blocking collaterals”. Alternatively, of the 14 treatment methods, the top three treatments with frequency of ≥ 3 included “Activating Yang and eliminating turbidity, and removing phlegm and dredging channel blockage” “Strengthening the spleen and benefiting Qi, and eliminating phlegm to activate the channels”, and “Warming Yang and benefiting Qi, and expelling cold to remove obstructions”. Among the 15 prescriptions, the top three used with frequency ≥ 3 included Huangqi Guizhi Wuwu Tang (黄芪桂枝五物汤), Gualou Xiebai Banxia Tang (瓜蒌薤白半夏汤), and Ganjiang Huangqin Huanglian Renshen Tang (干姜黄芩黄连人参汤). Lastly, of the 83 drugs used for a total of 476 times, those with frequency ≥ 15 included Huanglian (Coptidis Rhizoma), Huangqi (Astragali Radix), Jiudahuang (Wine-processed Rhei Radix et Rhizoma), Jixueteng (Spatholobi Caulis), Shengjiang (Zingiberis Rhizoma Recens), Huangqin (Scutellariae Radix), and Guizhi (Cinnamomi Ramulus). (ii) For the drug-drug associations, under the criteria of support ≥ 15% and confidence = 100%, seven second-order association rules, seven third-order rules, and six fourth-order roles were identified. The top-ranking rule of each was “Huangqin (Scutellariae Radix) → Huanglian (Coptidis Rhizoma)” “Ganjiang (Zingiberis Rhizoma) + Huangqin (Scutellariae Radix) → Huanglian (Coptidis Rhizoma)”, and “Baishao (Paeoniae Radix Alba) + Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) → Huangqin (Scutellariae Radix)”, respectively. Alternatively, the drug-symptom associations were analyzed under the criteria of support ≥ 5% and confidence = 100%, which derived eight second-order association rules, 31 third-order rules, and 30 fourth-order rules. The top-ranking association rule of each order was “Huangqi (Astragali Radix) → Limb edema” “Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) → Limb numbness and pain”, and “Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) + Huangqi (Astragali Radix) → Limb numbness and pain”, respectively. Similarly, the drug-western medicine index associations were investigated under the criteria of support ≥ 5% and confidence = 100%, and five second-order association rules, 16 third-order rules, and 16 fourth-order rules were identified. In this category, the top-ranking association rule of each order was “Qinpi (Fraxini Cortex) → Uric acid” “Huanglian (Coptidis Rhizoma) + Ganjiang (Zingiberis Rhizoma) → Glycated hemoglobin”, and “Huanglian (Coptidis Rhizoma) + Ganjiang (Zingiberis Rhizoma) + Huangqin (Scutellariae Radix) → Glycated hemoglobin”, respectively. Conclusion Through association rule mining, this study objectively and quantitatively demonstrated the drug-drug, drug-symptom, and drug-physicochemical index associations of patients with the spleen dampness syndrome at the splenic deficiency and impairment stage treated by Academician TONG Xiaolin. The results indicated that treatment for these patients adopted the “state-target” syndrome differentiation method. The drug combination was characterized by “small prescriptions”, targeting both the patient’s symptoms and signs (syndrome target) and western medicine indices (treatment target). This study could provide references for future research on the academic thoughts and medical experience of Academician TONG Xiaolin.

This study is to identify Chinese medicinal materials Rhizoma et Radix Heraclei, Angelicae Sinensis, Radix Angelicae Pubescentis and Rhizoma et Radix Notopterygii based on ITS2 and its secondary structure. Total 26 ITS sequences of 7 species were downloaded from GenBank, the ITS2 sequences were annotated by HMMer method. The NJ phylogenetic tree was built by MEGA software, the intraspecific and interspecific K2P genetic distance were analyzed by MEGA as well. The ITS2 secondary structures of all taxa were predicted by ITS2 database. Sequence matrix of primary structure and secondary structure was aligned by 4Sale software. And the profile neighbor joining (PNJ) phylogenetic tree was constructed via the the ProfDistS software based on the distance method. The results show that, the average interspecific genetic distance was far greater than the average intraspecific genetic distance, an obvious barcoding gap was noted among all taxa; NJ tree showed that all species were clustered into seperate branches; each species had different secondary structures; the PNJ tree showed higher resolution than NJ tree. Therefore, ITS2 is suggested to be used as a barcode for distinguishing the original plants of Rhizoma et Radix Heraclei, Radix Angelicae Sinensis, Radix Angelicae Pubescentis and Rhizoma et Radix Notopterygii in this study, this provides some scientific basis for classification and accurate identification of these Chinese medicinal materials.
