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.

Objective Studies on the expression and location of zinc finger protein A20 (A20) and connective tissue growth factor (CTGF) in liver tissues of patients with chronic hepatitis B were conducted, and the relationship between them and liver fibrosis was determined by FibroScan. Methods Studies on A20 and CTGF in liver tissues of 160 patients with chronic hepatitis B were conducted in accordance with the stage of pathological fibrosis and inflammation of the liver, and quantitative immunohistochemistry test was conducted, and statistical analysis was conducted by FibroScan. Results The expressions of A20 and CTGF in liver tissues increased with the aggravation of liver pathological fibrosis and inflammation, and there were significant differences between each stage and the control group (P<0.05), and there were significant differences between adjacent groups (P<0.05). Studies have shown that FibroScan increases along with pathological fibrosis and inflammation in the liver. There are significant differences between the stage and the control group (P<0.05), and no significant differences between the adjacent groups (P>0.05). There was positive correlation between liver A20 and CTGF, r=0.796 (P<0.05). Conclusions In patients with chronic hepatitis B, A20, CTGF and FibroScan are positively correlated with the degree of liver fibrosis, and A20 and CTGF are also positively correlated with the degree of liver inflammation, which can be used as indicators to evaluate the degree of liver inflammation and fibrosis, and further guide the anti-inflammatory and anti-fibrosis treatment of patients.

Osteoarthritis （OA） is characterized by articular cartilage degeneration， synovial hyperplasia， hyperosteogeny， and narrowing of joint space， which can be caused by trauma， inflammation， and other factors. With the increasing global population aging， the incidence of OA is rising year by year， making it a major public health problem that urgently needs to be addressed. Exploring effective treatment schemes is particularly important. The pathogenesis of OA is complex， including oxidative stress， autophagy， and apoptosis. Recent studies have found that ferroptosis， a new type of cell death， is also an important pathogenic factor in OA， characterized by a series of complex changes such as iron ion accumulation， glutathione （GSH） depletion， and mitochondrial dysfunction. Research shows that inhibiting ferroptosis in chondrocytes can promote chondrocyte proliferation， delay extracellular matrix （ECM） degradation， and reduce synovial hyperplasia and inflammation. Targeting ferroptosis is a new direction in the treatment of OA. OA treatment includes intra-articular injections of steroids or hyaluronic acid and artificial joint replacement， but there are limitations. Traditional Chinese medicine （TCM） has been widely used in the treatment of various diseases because of its low cost， low drug resistance， and few side effects. Cell and animal experiments have further confirmed that TCM can intervene in the treatment of OA with ferroptosis from multiple targets， multiple levels， and aspects， but the mechanism of its treatment of OA based on ferroptosis has not been clarified. This paper discussed iron metabolism， lipid peroxidation， cysteine/glutamate transporter system Xc^- （system Xc^-）/GSH/glutathione peroxidase 4 （GPX4） pathway， nicotinamide adenine dinucleotide phosphate（NADPH）/ferroptosis suppressor protein 1 （FSP1）/coenzyme Q₁₀ （CoQ₁₀） pathway， tumor protein p53 in OA， and related molecular targets of Chinese medicine monomers and compounds on ferroptosis inhibition. Their potential therapeutic mechanisms were further analyzed to provide theoretical guidance for the treatment of OA by TCM and useful reference for the research and development of related drugs.

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.

OBJECTIVE To characterize paclitaxel nanoparticles （PTX-PLGA-NPs） and evaluate their in vitro inhibitory effect on Lewis lung cancer cells. METHODS The PTX-PLGA-NPs prepared by the emulsion-solvent evaporation method were characterized in terms of particle size， polydispersity index （PDI）， Zeta potential， microscopic morphology， encapsulation efficiency， drug loading， ultraviolet-visible absorption characteristics and stability. Using mouse Lewis lung cancer cells as the subjects and paclitaxel reference substance as the control， the cytotoxicity and in vitro killing activity of PTX-PLGA-NPs were detected using CCK-8 method and Calcein-AM/PI double staining method， respectively. The effects of PTX-PLGA-NPs on cell apoptosis and cell cycle were assessed by Annexin Ⅴ-FITC/PI staining method and PI staining method， respectively. RESULTS PTX-PLGA-NPs were spherical with an average particle size of （172.03±0.95） nm， PDI of 0.098±0.012， and Zeta potential of （－1.76±0.02） mV. The encapsulation efficiency and drug loading were （52.32±0.66）% and （7.07±0.18）%， respectively， and the ultraviolet-visible absorption characteristics were not affected by the carrier polylactic-co-glycolic acid. When stored in the dark at 4 °C for 7 days， no significant change was noted in particle size， and the average PDI （after 1， 2， 4 and 7 days of storage） was under 0.3. Compared with the paclitaxel reference substance group， the PTX-PLGA-NPs group had more cells in a state of death， the survival rate （at the PTX concentration of 11.2 μg/mL） was significantly decreased， and both the apoptosis rate and the proportion of G2 phase cells were significantly increased （P＜0.05）. CONCLUSIONS The prepared PTX-PLGA-NPs indicate homogeneity in particle size， uniform dispersion， stable properties， and stronger in vitro killing effect on lung cancer cells than PTX.

Objective To investigate the expression level and clinical application value of serum resistin in patients with systemic lu-pus erythematosus(SLE).Methods Forty-five SLE patients visited Nanjing Drum Tower Hospital,Clinical College of Nanjing Uni-versity of Chinese Medicine from January to August 2023 were enrolled in the study.The patients were scored and grouped according to the SLE disease activity index(SLEDAI),with SLEDAI＜9 score in the inactive group(n=32)and SLEDAI≥9 score in the active group(n=13).Thirty-four healthy individuals who underwent physical examination in our hospital were recruited as healthy controls.The clinical data and laboratory related indicators such as urine protein and serum complement C3 levels were collected from SLE pa-tients and healthy controls.Serum resistin levels were detected by enzyme-linked immunosorbent assay(ELISA).The clinical screening value of serum resistin for SLE was evaluated with the receiver operating characteristic(ROC)curve.The correlations of serum resistin levels with different laboratory indicators were determined by Pearson correlation analysis.Results The serum resistin levels in SLE patients([7.64±0.64]ng/mL)were significantly higher than that in healthy controls([2.56±0.43]ng/mL),and the difference was statistically significant(t=6.195,P＜0.01).The serum resistin levels in active SLE patients([10.10±1.45]ng/mL)were significant-ly higher than that in inactive SLE patients([6.64±0.60]ng/mL),and the difference was statistically significant(t=2.632,P＜0.05).The area under the ROC curve(AUCROC)of serum resistin for screening SLE was 0.897.When the cut-off value was 5.893 ng/mL,the sensitivity was 86.67%and the specificity was 82.35%.The serum resistin level in SLE patients was positively correlated with urine protein(r=0.692,P＜0.01),while negatively correlated with serum complement C3(r=-0.354,P＜0.05).Conclusion The expression levels of serum resistin in SLE patients are significantly increased and positively correlated with SLE disease activity and urine protein.Serum resistin may become a novel biomarker for the diagnosis and therapeutic effect assessment of SLE.

Background Suicidal ideation serves as a sensitive predictive indicator for non-suicidal self-injury(NSSI)behavior,and NSSI behavior brings profound effects to both mental and physical health of senior high school students.Existing studies have made exploration on the relationship among insomnia,anxiety and NSSI behavior in the general population,but the internal mechanism of NSSI behavior in senior high school students with suicidal ideation requires further study.Objective To explore the pathway of anxiety between insomnia and NSSI behavior in senior high school students,so as to provide references for the intervention on NSSI behavior in such demographic.Methods From December 10 to 15,2021,cluster sampling was adopted to select 2 572 senior high school students across three senior high schools in Hubei Province as the research objects.Assessment was conducted by using Insomnia Severity Index(ISI),Generalized Anxiety Disorder Scale-7 item(GAD-7)and Adolescents Self-Harm Scale.Spearman correlation analysis was conducted to examine the correlation among scores of scales finished by senior high school students with suicidal ideation.Model 4 from the SPSS 20.0 Process 4.2 was employed to test the mediating path of anxiety between insomnia and NSSI behavior.Results A total of 2 421 valid questionnaires(94.13%)were recovered,which revealed 554 cases(22.88%)with suicidal ideation and 408 cases(16.85%)with NSSI behavior.The scores of ISI,GAD-7 and Adolescents Self-Harm Scale of senior high school students with suicidal ideation were higher than those of students without suicidal ideation(Z=17.124,20.611,21.314,P<0.01).As correlation analysis showed,the ISI score of senior high school students with suicidal ideation was positively correlated with scores of GAD-7 and Adolescents Self-Harm Scale(r=0.646,0.354,P<0.01),and GAD-7 score was positively correlated with the score of Adolescents Self-Harm Scale(r=0.375,P<0.01).Among senior high school students with suicide ideation,anxiety acted in a mediating role between insomnia and NSSI behavior,with effect value of 0.111(95%CI:0.053～0.185),accounting for 53.88%of the total effect.Conclusion Insomnia of senior high school students with suicidal ideation can not only directly affect NSSI behavior,but also indirectly affect NSSI behavior through anxiety.

Background::There is a need for effective and safe therapies for psoriasis that provide sustained benefits. The aim of this study was to assess the efficacy and safety of tildrakizumab, an anti-interleukin-23p19 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in Chinese patients.Methods::In this multi-center, double-blind, phase III trial, patients with moderate-to-severe plaque psoriasis were enrolled and randomly assigned (1:1) to receive subcutaneous tildrakizumab 100 mg or placebo at weeks 0 and 4. Patients initially assigned to placebo were switched to receive tildrakizumab at weeks 12, 16, and every 12 weeks thereafter. Patients in the tildrakizumab group continued with tildrakizumab at week 16, and every 12 weeks until week 52. The primary endpoint was the Psoriasis Area and Severity Index (PASI 75) response rate at week 12.Results::At week 12, tildrakizumab demonstrated significantly higher PASI 75 response rates (66.4% [73/110] vs. 12.7% [14/110]; difference, 51.4% [95% confidence interval (CI), 40.72, 62.13]; P <0.001) and Physician’s Global Assessment (60.9% [67/110] vs. 10.0% [11/110]; difference, 49.1% [95% CI, 38.64, 59.62]; P <0.001) compared to placebo. PASI 75 response continued to improve over time in both tildrakizumab and placebo-switching to tildrakizumab groups, reaching maximal efficacy after 28 weeks (86.8% [92/106] vs. 82.4% [89/108]) and maintained up to 52 weeks (91.3% [95/104] vs. 87.4% [90/103]). Most treatment-emergent adverse events were mild and not related to tildrakizumab. Conclusion::Tildrakizumab demonstrated durable efficacy through week 52 and was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis.Trial registration::ClinicalTrials.gov, NCT05108766.

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.
