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.

Conclusion:The ventilation facilities of the inspection workshop are set up in the airflow organization mode of sending up and down the exhaust, and the ventilation pipes are scientifically designed through the calculation of ventilation hydraulic balance, which can effectively control the concentration of harmful gases in the inspection workshop.

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.

Objective:To investigate the diagnostic value of magnetically controlled capsule gastroscope in elderly patients with suspected upper gastrointestinal bleeding.Methods:A total of 102 patients with suspected upper gastrointestinal bleeding who underwent magnetically controlled capsule gastroscopy (MCCG) in General Hospital of Ningxia Medical University from October 2020 to September 2022 were enrolled. Patients were divided into two groups according to age: 38 patients in group A (≤65 years old) and 64 patients in group B (> 65 years old). The case data, changes of vital signs, detection of lesions and adverse reactions of the two groups were compared.Results:There were significant differences in combined diseases between group A and group B. The stomach examination time in group A was significantly shorter than that of group B (15.49±2.04 min VS 16.61±2.02 min, t=-2.685, P=0.009). There was significant difference in small intestine examination time between the two groups (331.69±14.96 min VS 337.83±14.28 min, t=-1.229, P=0.227). The incidence of adverse reactions in group A was significantly lower than that in group B [0.00%(0/38) VS 6.25%(4/64), χ2=6.186, P=0.013]. The changes of vital signs before, during and after examination were not statistically different. The detection rates of upper gastrointestinal lesions were 92.1% (35/38) and 98.4% (63/64), respectively. The positive rates of upper gastrointestinal bleeding under MCCG were 60.0% (21/35) and 50.8% (32/63), respectively. Patients with unexplained upper gastrointestinal bleeding under MCCG received small intestine examination. The detection rates of small intestinal lesions by small intestine examination were 84.6% (11/13) and 91.7% (22/24), respectively. Conclusion:MCCG demonstrates excellent diagnostic accuracy in elderly patients with suspected upper gastrointestinal bleeding. Additionally, it is safe and suitable for use in elderly patients with multiple comorbidities, allowing for concurrent small intestine examination.

Objective:This study aims to evaluate the performance of digital PCR (dPCR) detecting multiple and single copies genes of the Epstein-Barr virus (EBV) for nucleic acid quantification and explore their applicability in clinical settings.Methods:Compared the sensitivity, specificity, precision, lower limit of detection (LoD), and linearity for multicopy BamHI-W dPCR and single-copy EBNA1 dPCR systems. Linear regression analysis using the least squares method was employed to evaluate the linearity. Additionally, we analyzed plasma samples from 182 patients with suspected EBV-related diseases between January and July 2022 at the Southern Medical University Southern Hospital, using both dPCR and quantitative PCR (qPCR) for EBV DNA quantification. Linear regression analysis using the least squares method was conducted to assess their quantitative correlation.Results:The dPCR systems for both multicopy and single-copy genes showed excellent linearity ( R 2 values of 0.992 and 0.997, respectively, both P<0.001). The LoD were 188 IU/ml for BamHI-W gene and 358 IU/ml for EBNA1 gene dPCR systems. The logarithmic coefficient of variation ( CV) values for high-concentration samples (1 000 000 IU/ml) were 0.34% and 0.21% for the BamHI-W gene and EBNA1 gene dPCR assays, respectively, while for low-concentration samples (5 000 IU/ml) were 0.98% and 0.64%, respectively. In the detection of seven common clinical infectious pathogens and EBV positive samples, only EBV-positive samples yielded positive signals in the dPCR detection system, with no cross-reaction with other pathogens. In 182 samples, the positive detection rates were 47.80% (87/182) for BamHI-W gene and 35.16% (64/182) for EBNA1 gene dPCR, compared to 43.41% (79/182) for qPCR. Linear correlation analysis with qPCR showed R2 values of 0.837 for BamHI-W gene and 0.763 for EBNA1 gene dPCR (both P<0.001). The BamHI-W gene copy number ranged from 3 to 18 copies per clinical sample, with patient-specific variations. There was a high consistency in viral load trends between the multicopy BamHI-W gene and single-copy EBNA1 gene dPCR systems within individual patients. Conclusions:The dPCR methods detecting EBV multiple and single copies genes showed high sensitivity, specificity, precision, and quantitative accuracy, suitable for clinical sample analysis. The multicopy BamHI-W gene dPCR method notably enhances detection sensitivity and can be used as a supplement to current EBV DNA load detection methods, especially in low-concentration samples. For within-patient EBV DNA monitoring, the multicopy gene method proves more effective, while inter-patient comparisons might necessitate single-copy gene methods or normalize them using the same standard.

Purpose To investigate the expression of TRPS1 in synovial sarcoma(SS)and its significance.Methods Twenty-one cases of synovial sarcoma diagnosed by SS1 8(18q11)(SYT)fluorescence in situ hybridization(FISH)or SS18-SSX immunohistochemistry were collected.The expression of TRPS1 was detected by immunohistochemistry EnVision two-step staining,and the relevant literature was reviewed.Results There were 21 cases of synovial sarcoma,including 9 females and 12 males,aged 17-79 years,with a median age of 50 years and an average age of 47.1 years.The tumors occurred in the lung(3 cases),legs(3 cases),kidney(3 cases),feet(2 cases),psoas major muscle(2 cases),rectum(1 case),tho-racic cavity(1 case),ankle canal(1 case),inguinal area(1 case),knee(1 case),palm(1 case),nasal cavity(1 case),and forearm(1 case).The maximum diameter of the tumor was 1.2-13 cm.Grossly,the tumor section was grayish-white,grayish-yellowish solid,and the lesion with hemorrhage was dark red.Microscopically,there were monophasic fibrous SS(16/21,76.2％),poorly differential SS(small cell)(3/21,14.3％),and biphasic SS(2/21,9.5％).Immunophenotypi-cally,tumor cells expressed SS18-SSX(18/18,100％),TLE1(12/12,100％),BCL2(18/18,100％),partially expressed EMA(10/16,62.5％),CK(12/18,66.7％),CD99(4/10,40.0％),SMA(3/16,18.6％),S-100(3/19,15.8％),and desmin(0/21).The proliferation index of Ki67 ranged from 3％-80％,with an average of 39.9％.FISH test showed that all 11 cases were positive for SS18(18q11)split-ting.All 21 cases of SS expressed TRPS1 to varying degrees and intensities(21/21,100％),of which 19 cases(19/21,90.5％)had a positive range of＞50％.There were 19 cases(19/21,90.5％)with a positive intensity of 2+or above.All the 21 patients underwent surgical resection of the tumor,and 20 patients received follow-up visits.3 patients treated with postop-erative combination of radiotherapy and chemotherapy,18 pa-tients treated with postoperative chemotherapy,and 7 patients showed different degrees of recurrence or metastasis,and 9 pa-tients who received follow-up visits died(45％,9/20).Con-clusion Although TRPS1 is regarded as a highly sensitive and specific marker of breast tumor origin,it is also highly expressed in synovial sarcoma,and it is necessary to be vigilant at its pit-falls in the pathological diagnosis.

Objective:To evaluate the prognosis of patients with primary thyroid malignant lymphoma (PTL) treated with total thyroidectomy alone or in combination with R-CHOP chemotherapy, and analyze the factors influencing their prognosis.Methods:A retrospective analysis was conducted on 62 patients with PTL admitted to the Hematology Department of Shanxi Provincial Cancer Hospital from Jan. 2009 to Jan. 2020. The patients were with an average age of (63.51±9.83) years, with 20 males and 42 females. According to Ann Arbor staging and patients' wishes, 10 cases received simple thyroidectomy, 47 cases received total thyroidectomy +R-CHOP, and 5 cases received total thyroidectomy +R-CHOP+ radiotherapy. After 3 months of treatment, the short-term curative effect was collected. According to the prognosis of patients after 24 months of follow-up, the dead cases were classified into bad group and the surviving cases into good group. Single factor and LASSO regression dimensionality reduction were used to screen the influencing factors, and Logistic regression analysis was used to analyze the influencing factors of PTL prognosis.Results:Among 62 patients with PTL, 21 (33.87%) had complete response (CR), 27 (43.55%) had partial response (PR), 9 (14.52%) had stable disease (SD), and 5 (8.06%) had progressive disease (PD). After a follow-up of 24 months, the mortality rate among 10 patients who underwent surgical treatment alone was 90% (9/10), the mortality rate among those who underwent surgical treatment combined with R-CHOP therapy was 19.15% (9/47) ,18 deaths were categorized as having a poor prognosis, while 44 survivors were classified as having a favorable prognosis.Univariate, LASSO regression screening, and Logistic regression analysis showed that Ann Arbor staging ( OR=5.105), pathological type ( OR=3.622), international prognostic index (IPI) score ( OR=2.709), treatment method ( OR=0.730), hemoglobin ( OR=0.392), and lactate dehydrogenase (LDH) ( OR=6.469) were factors affecting the prognosis of PTL (all P<0.05) . Conclusions:The combined use of total resection and R-CHOP treatment for patients has a superior prognosis compared to patients undergoing total resection alone. Furthermore, the prognosis of patients is also influenced by factors such as Ann Arbor staging and IPI scoring. Based on this, clinical care plans can be refined to improve the prognosis.

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.

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.
