OBJECTIVE To explore the effects of Polygala tenuifolia compatibility on toxicity, anti-inflammatory and analgesic efficacy of sand-ironing Strychnos nux-vomica (SS). METHODS The preparation of SS single decoction, SS-P. tenuifolia core-removed (PC) (1∶2.5) or (1∶5) combined decoction, and SS-PC (1∶5) mixture were carried out to investigate their median lethal dose (LD50). Using aspirin as positive control, the number of writhing movements, analgesic rate, pain latency, ear swelling degree and inflammation inhibition rate induced by the above-mentioned medicinal liquids in mice were compared. The contents of the active and toxic components, strychnine and brucine, in the above-mentioned medicinal liquids were also determined. RESULTS The LD50 values of SS single decoction, SS-PC (1∶2.5) combined decoction, SS-PC (1∶5) combined decoction and SS- PC (1∶5) mixture were 302.00, 614.47, 1 445.44 and 1 778.28 mg/kg, respectively. Compared with control group, the number of writhing movements and ear swelling degree in the mice of the above-mentioned medicinal liquid groups were reduced or decreased significantly (P<0.05 or P<0.01); pain latency [at 90 and 120 minutes in the SS single decoction group, at 60 and 90 minutes in the SS-PC (1∶2.5) combined decoction group, and at 60,90, 120 minutes in the SS-PC (1∶5) combined decoction group and SS-PC (1∶5) mixture group] was significantly prolonged (P<0.05 or P<0.01); analgesic rates of the respective medicinal liquids were 39.30%, 70.87%, 80.00% and 82.46%, and inflammation inhibition rates were 38.08%,TD 57.89%, 76.47% and 50.46%; analgesic and anti-inflammatory effects of combined decoction and mixture were generally better than those of the single decoction (P<0.05 or P<0.01). In the above-mentioned four medicinal liquids, the total contents of strychnine were 0.71%, 0.42%, 0.47% and 0.64%, and the total contents of brucine were 0.88%, 0.63%, 0.57% and 0.88%, respectively. CONCLUSIONS The combination of P. tenuifolia can reduce the toxicity of SS and enhance its anti-inflammatory and analgesic effects. Moreover, there is a tendency for the toxicity-reducing and efficacy-enhancing effects to increase with the increasing dosage of P. tenuifolia. Additionally, the combined decoction of SS and P. tenuifolia can reduce the contents of the active and toxic components, strychnine and brucine, in SS.

Abstract
Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

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.

ObjectiveThe human angiotensin converting enzyme2 (hACE2) transgenic mouse model was used to clarify the antiviral efficacy of BD-77 against a novel coronavirus SARS-CoV-2 and explore the action mechanism of BD-77 against SARS-CoV-2. MethodSARS-CoV-2 Omicron and Delta variant strains-infected VeroE6 cell models were established and administered with BD-77 to observe the antiviral effect of BD-77 in vitro. A kit was used to detect the effect of BD-77 in vitro on the binding of spike S protein of SARS-CoV-2 virus (Delta/Omicron) to angiotensin converting enzyme2 (ACE2). Chromatography was adopted to detect the binding of BD-77 to the S protein and N protein of the novel coronavirus. hACE2 transgenic C57BL/6 mice were divided into a blank control group, SARS-CoV-2 infection group, BD-77 administration groups of 37.5 mg·kg-1 and 75 mg·kg-1, with eight mice in each group. The pneumonia model of SARS-CoV-2-infected hACE2 transgenic mice was built to observe the survival of the mice, detect the virus titer of the lung tissue of the mice, and observe the lesions in the lung tissue. ResultBD-77 had a certain inhibitory effect on Omicron and Delta variant strains in vitro, with median inhibitory concentration (IC50) of 526.3 mg·L-1 and 653.0 mg·L-1, respectively. BD-77 had no significant inhibitory effect on the binding of the S protein of WT, Omicron, and Delta variant strains of SARS-CoV-2 to ACE2 and had no binding effect with the S protein and N protein of the novel coronavirus. No mice in the blank group died, while the mortality rate of SARS-CoV-2-infected mice was 75%. There was a large amount of virus replication in the lung tissue of the mice and large areas of inflammatory infiltration in the lung tissue and interstitium. Compared with the model group, BD-77 administration groups of 37.5 mg·kg-1 and 75 mg·kg-1 could reduce the mortality of mice, significantly lower the virus titer in the lung tissue of mice (P<0.05), and improve lung lesions. ConclusionBD-77 demonstrated significant inhibitory effects against SARS-CoV-2 virus in vitro and in vivo. However, its mechanism of action did not involve direct inhibition of the virus itself or intervention in the virus-host binding process. This finding suggests that the mechanism of action of BD-77 needs to be thoroughly investigated and elucidated by further experiments.

Cinnamomi Ramulus and Alismatis Rhizoma are commonly used in the treatment of external-contraction diseases. Cinnamomi Ramulus is pungent, sweet, and warm, with the effects of ventilating lung and dispersing cold, warming Yang and transforming Qi, and promoting water and liquid flow from Taiyang meridian to remove dampness. Alismatis Rhizoma is sweet and cold, with the effects of draining dampness and promoting urination, regulating the waterway, removing water retention in lung, and promoting urination to remove dampness and heat. Herbal pairs are extracted from the accumulated experience of medical practitioners over the ages in the use of medicines and have been proved by clinical application to be composed of simple and effective combinations for specific diseases. The herb pair Cinnamomi Ramulus-Alismatis Rhizoma is an important part in ancient classic formulas such as Wulingsan. Both herbs play a role in draining dampness and promoting urination, warming Yang and transforming Qi, being a representative herb pair used for treating external-contraction exterior syndrome and water retention inside. The review of ancient medical publications revealed that there were a large number of compound formulas containing Cinnamomi Ramulus-Alismatis Rhizoma for dispersing cold and removing dampness, which were widely used for thousands of years in clinical practice. Modern pharmacological studies have shown that the active pharmacological components of Cinnamomi Ramulus (cinnamaldehyde and cinnamic acid) and Alismatis Rhizoma (alisol A and 23-acetate alisol B) have anti-inflammatory, antiviral, and immunoregulatory effects and high safety. Qingfei Paidu decoction containing this herbal pair played an important role in fighting against COVID-19. Despite the extensive pharmacological studies on Cinnamomi Ramulus and Alismatis Rhizoma, few studies have been carried out regarding this herb pair. This paper summarizes the traditional Chinese medicine knowledge about Cinnamomi Ramulus and Alismatis Rhizoma in the treatment of external-contraction diseases and summarizes the chemical composition, pharmacological effects, toxicology and other aspects of the two herbs before and after compatibility, aiming to provide a reference for further research and clinical application.
