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.

OBJECTIVES: To evaluate the protective effect of Schistosoma japonicum cystatin (rSj-Cystatin) in a mouse mode of "two-hit" sepsis. METHODS: Sixty male C57BL/6 mice randomized equally into sham-operated group, protein group, "two-hit" modeling group, and protein intervention group. In the former two groups, the mice received an intraperitoneal injection of 100 μL PBS followed by exposure of the cecum and then by intraperitoneal injection of 100 μL PBS or 25 μg rSj-Cystatin 30 min later; In the latter two groups, 100 μL PBS containing LPS (5 mg/kg) was injected intraperitoneally 24 h before cecal ligation and puncture (CLP), and 100 μL PBS or 25 μg rSj-Cystatin were injected 30 min after CLP. At 12 h after rSj-Cystatin treatment, 6 mice from each group were sacrificed for detection of TNF-α, IL-6, IL-10, TGF-β, iNOS and Arg-1 in the serum, spleen, liver, lung and kidney tissues using ELISA, for examinations of liver, lung and kidney pathologies with HE staining, and for analysis of CD3⁺CD4⁺CD25⁺Foxp3⁺ T cell percentage in the spleen using flow cytometry. The remaining mice were observed for general condition and 72-h survival. RESULTS: The 72-h survival rates in the 4 groups were 100%, 100%, 0% and 20%, respectively, showing significant differences between the latter two groups. The mouse models of "two-hit" sepsis exhibited obvious tissue pathologies and significant elevations of TNF-α and IL-6 in both the serum and tissue homogenate, which were significantly ameliorated by rSj-Cystatin treatment. Treatment with rSj-Cystatin also increased IL-10 and TGF-β levels and spleen CD3⁺CD4⁺CD25⁺Foxp3⁺ T cell percentage. The septic mouse models also showed increased iNOS levels in all the detected tissues and a decreased Arg-1 level in the kidney, and these changes were obviously improved by rSj-Cystatin treatment. CONCLUSIONS rSj-Cystatin has a protective effect against "two-hit" sepsis in mice by regulating the inflammatory microenvironment.

Objective To compare the short-term efficacy and safety of low temperature plasma radiofre-quence ablation(LA)vs.high voltage long duration pulsed radiofrequency(HL-PRF)in the treatment of cervico-genic headache(CEH).Methods Eighty patients with cervicogenic headache were divided two groups:one treated with low temperature plasma radiofrequence ablation group as group L(n = 50)and the other treated with high voltage long duration pulsed radiofrequency group as group H(n = 30).The two groups were compared in terms of the score by the Visual Analog Scale,score by the Range of Motion Scale,postoperative pain relief rate,postop-erative complication incidence,1,4,12,and 24 weeks after the operation,as well as the therapeutic effectiveness and safety.Results Both groups showed significantly lower VAS and ROM scores after operation(P<0.05).Compared with group L,group H had significantly lower VAS(all P<0.05)but insignificantly lower ROM scores(all P>0.05)at each time point.At T4,group H had significantly higher therapeutic effectiveness rate(P<0.05)and higher incidence of scalp numbness at T3,as compared to group L(P<0.05).Conclusion The low tempera-ture plasma radiofrequency ablation and high voltage long duration pulsed radiofrequency both are effective and safe in the treatment of CEH,the latter approach can achieve better therapeutic effectiveness 24 weeks after the operation than the former.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective To investigate the relationship between serum levels of E-cadherin and β-catenin and calcium phosphorus metabolism and carotid artery calcification in patients with diabetic nephropathy.Methods A total of 112 patients with diabetic nephropathy admitted to the hospital from May 2019 to No-vember 2022 were selected as the study group,and were divided into a carotid artery calcification group(n=44)and a non-carotid artery calcification group(n=68)according to the results of bilateral carotid artery col-or Doppler ultrasound.In addition,90 healthy people who underwent physical examination in the hospital dur-ing the same period were selected as the control group.Serum E-cadherin,β-catenin,calcium phosphorus me-tabolism levels were detected and compared.Pearson correlation analysis was used to explore the relationship between serum E-cadherin,β-catenin and calcium phosphorus metabolism in patients with diabetic nephropa-thy.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of serum E-cad-herin and β-catenin for carotid artery calcification in patients with diabetic nephropathy.Multivariate Logistic regression analysis was used to explore the influencing factors of carotid artery calcification in patients with di-abetic nephropathy.Results The levels of glycosylated hemoglobin,serum phosphorus,calcium-phosphorus product,parathyroid hormone(iPTH),creatinine,alkaline phosphatase and β-catenin in the study group were higher than those in the control group,and the level of E-cadherin was lower than that in the control group(P＜0.05).The levels of serum phosphorus,serum calcium,calcium phosphorus product,iPTH,creatinine,al-kaline phosphatase and β-catenin in the carotid artery calcification group were higher than those in the non-ca-rotid artery calcification group,and the level of E-cadherin was lower than that in the non-carotid artery calci-fication group(P＜0.05).Pearson correlation analysis showed that serum E-cadherin level in patients with di-abetic nephropathy was negatively correlated with serum phosphorus,serum calcium,calcium phosphorus product,iPTH,creatinine and alkaline phosphatase(r=-0.453,-0.654,-0.365,-0.490,-0.411,-0.377,all P＜0.001).The level of serum β-catenin was positively correlated with serum phosphorus,serum calcium,calcium phosphorus product,iPTH,creatinine,and alkaline phosphatase(r=0.444,0.345,0.421,0.398,0.651,0.622,all P＜0.001).ROC curve analysis showed that the area under the curve of serum E-cad-herin,β-catenin and their combination for predicting carotid artery calcification in diabetic nephropathy were 0.844(95％CI 0.795-0.894),0.853(95％CI 0.801-0.901)and 0.901(95％CI 0.801-0.901),respec-tively.Multivariate Logistic regression analysis showed that serum E-cadherin(OR=3.789,95％CI 2.055-6.983),β-catenin(OR=4.104,95％CI 1.795-9.385),calcium phosphorus product(OR=2.998,95％CI 1.895-4.743)and iPTH(OR=2.713,95％CI 1.787-4.118)were the influencing factors of carotid artery calcification in patients with diabetic nephropathy(P＜0.05).Conclusion The level of β-catenin is increased and the level of E-cadherin is decreased in patients with diabetic nephropathy.β-catenin and E-cadherin are closely related to calcium phosphorus metabolism and carotid artery calcification,which could be used as effec-tive indicators to evaluate carotid artery calcification in patients with diabetic nephropathy.The combination ofβ-catenin and E-cadherin has a higher predictive value for carotid artery calcification.

Objective To investigate the relationship between serum levels of growth differentiation factor-11(GDF-11)and S100 calcium binding protein A4(S100A4)and the severity and disease outcome in diabetic nephropathy(DN)patients.Methods A total of 95 DN patients admitted to the hospital from May 2021 to January 2023 were selected as the study group,and 110 healthy people were selected as the healthy group.The DN patients were divided into mild group(n=66)and severe group(n=29)according to the severity of the disease.The patients were followed up for half a year after discharge,and were divided into good prognosis group(n=64)and poor prognosis group(n=31)according to the prognosis.Serum GDF-11 and S100A4 lev-els were detected by enzyme-linked immunosorbent assay.Spearman rank correlation analysis was used to ex-plore the relationship between serum GDF-11,S100A4 levels and the severity of the disease.Receiver operat-ing characteristic(ROC)curve was used to evaluate the predictive value of serum GDF-11 and S100A4 for dis-ease outcome in DN patients,and multivariate Logistic regression was used to analyze the influencing factors of disease outcome in DN patients.Results The levels of serum GDF-11 and S100A4 in mild group and severe group were higher than those in healthy group,and those in severe group were higher than those in mild group(P＜0.05).Serum GDF-11 and S100A4 levels were positively correlated with the severity of DN patients(P＜0.05).The good prognosis group had significantly lower serum levels of GDF-11 and S100A4 than the poor prognosis group(P＜0.05).The area under the curve(AUC)of serum GDF-11 and S100A4 in predicting the outcome of DN patients was 0.785 and 0.839,respectively,and the AUC of combined prediction was 0.902.The proportion of type 2 diabetes(T2DM)duration,glomerular grade Ⅲ-Ⅳ,interstitial inflammation score 2,interstitial fibrosis and tubular atrophy(IFTA)score 2-3 points,estimate glomerular filtration rate＜60 mL/(min·1.73 m2)and the levels of total cholesterol,triglyceride,low-density lipoprotein choles-terol,24 h urinary protein,glycosylated hemoglobin,C-peptide,hematocrit,and erythrocyte sedimentation rate in the good prognosis group were higher than those in the good prognosis group(P＜0.05).Multivariate Lo-gistic regression analysis showed that the duration of T2DM ≥12.0 years,IFTA score ≥2 points,GDF-11≥700.82 ng/mL,S100A4 ≥ 211.53 ng/L were risk factors for poor prognosis in DN patients(P＜0.05).Conclusion The levels of serum S100A4 and GDF-11 are highly expressed in patients with diabetes mellitus,and are related to the severity and outcome of the disease,which are expected to be potential markers for eval-uating the condition and prognosis of diabetes mellitus.

Objective To assess the effect of platycodin D(PD)for alleviating pulmonary fibrosis in mice and explore the underlying mechanism.Methods C57BL/6J mouse models of pulmonary fibrosis induced by bleomycin injection into the airway were treated with daily intragastric administration of 10 mg/kg PD for 28 days.The changes of pulmonary fibrosis and the expression and distribution of transient receptor potential cation channel subfamily C member 6(TRPC6)were evaluated with immunohistochemistry,HE staining and Sirius Red staining.Western blotting was used to detect α-SMA expression in the lung tissues of the mice.Primary cultures of mouse lung fibroblasts were pretreated with PD(2.5,5.0,and 10 μmol/L)or larixyl acetate(LA;10 μmol/L)before exposure to 10 ng/mL transforming growth factor-β1(TGF-β1),and the changes in cell survival rate,expressions of collagen I,α-SMA and TRPC6,reactive oxygen species(ROS)production,mitochondrial membrane potential,and cell proliferation capacity were assessed.Network pharmacology analysis was performed to explore the mechanism by which PD alleviated pulmonary fibrosis.Results PD treatment significantly alleviated pulmonary fibrosis and reduced α-SMA expression in BLM-induced mouse models(P<0.05).In TGF-β1-induced primary mouse lung fibroblasts,PD effectively inhibited the cell proliferation,reduced ROS production(P<0.0001),rescued the reduction of mitochondrial membrane potential(P<0.001),and inhibited the expressions of α-SMA and collagenⅠ(P<0.05).Network pharmacology analysis suggested that TRPC6 mediated the effect of PD for alleviating pulmonary fibrosis.Immunohistochemistry showed that PD significantly reduced TRPC6 expression in the lung tissues of BLM-induced mice.In primary mouse lung fibroblasts,PD significantly inhibited TGF-β1-induced TRPC6 expression(P<0.05),and LA treatment obviously lowered the expression levels of TRPC6,α-SMA and collagenⅠ(P<0.05).Conclusion PD alleviated pulmonary fibrosis in mice possibly by down-regulating TRPC6 and reducing ROS production.
