The development of traditional Chinese medicine (TCM) diagnosis and treatment has undergone multiple paradigms, evolving from sporadic experiential practices to systematic approaches in syndrome differentiation and treatment and further integration of disease and syndrome frameworks. TCM is a vital component of the medical system, valued alongside Western medicine. Treatment based on syndrome differentiation embodies both personalized treatment and holistic approaches; however, the inconsistency and lack of stability in syndrome differentiation limit clinical efficacy. The existing integration of diseases and syndromes primarily relies on patchwork and embedded systems, where the full advantages of synergy between Chinese and Western medicine are not fully realized. Recently, driven by the development of diagnosis and treatment concepts and advances in analytical technology, Western medicine has been rapidly transforming from a traditional biological model to a precision medicine model. TCM faces a similar need to progress beyond traditional syndrome differentiation and disease-syndrome integration toward a more precise diagnosis and treatment paradigm. Unlike the micro-level precision trend of Western medicine, precision diagnosis and treatment in TCM is primarily reflected in data-driven applications that incorporate information at various levels, including precise syndrome differentiation, medication, disease management, and efficacy evaluation. The current priority is to accelerate the development of TCM precision diagnosis and treatment technology platforms and advance discipline construction in this area.

Objective To explore the incidence rate and independent risk factors of synchronous multiple early gastric cancer (SMEGC) in patients with early gastric cancer, and to provide evidence for early screening and intervention of high-risk population. Methods A retrospective analysis was performed on 308 patients with early gastric cancer who received treatment in the hospital from March 2019 to March 2024. The incidence rate of SMEGC was counted, and the risk factors were analyzed by univariate and multivariate Logistic regression analyses. Results Among the 308 patients with early gastric cancer in this study, 23 cases were SMEGC and 285 were single early gastric cancer, which were included in the SMEGC group and the single group respectively. The incidence rate of SMEGC was 7.47% (23/308). Compared with the single group, the proportions of male, smoking history, tumor diameter≤2 mm, chronic atrophic gastritis and intestinal metaplasia degree were higher in the SMEGC group (2=4.331、8.608、4.618、6.490、4.897，P=0.037、0.003、0.032、0.001、0.027). Logistic regression analysis suggested that chronic atrophic gastritis (OR=3.133, 95%CI: 1.240-7.918) and moderate-to-severe intestinal metaplasia (OR=3.171, 95%CI: 1.252-8.029) were independent risk factors for SMEGC (P<0.05). Conclusion Some patients with early gastric cancer are SMEGC. Chronic atrophic gastritis and moderate-to-severe intestinal metaplasia are independent risk factors affecting the occurrence of SMEGC. It is recommended to regularly screen high-risk patients and optimize management strategies to reduce the risk of SMEGC.

Aim To establish the fingerprint of raw bupleurum and vinegar bupleurum,investigate the difference in their anti-liver fibrosis effects,and ex-plore the relationship between the chemical composition of raw bupleurum and vinegar bupleurum and their an-ti-liver fibrosis efficacy.Methods The fingerprints of 10 batches of raw bupleuri and 10 batches of bupleuri were established by UPLC method.The liver fibrosis cell model in vitro was established by TGF-β induced LX-2 hepatic stellate cells.The liver fibrosis cell mod-el was analyzed with collagen type Ⅰ(col1a1)and α-smoothmuscleactin.The expression of α-SMA protein was used as the pharmacodynamic index.MetaboAna-lyst5.0 was used to screen the difference markers af-fecting the quality of raw bupledges and vinegar bu-pledges with VIP value＞1 as the criterion.Orthogo-nal partial least squares discriminant analysis(OPLS-DA)was used to screen the main components of raw bupleurum and vinegar bupleurum against liver fibro-sis.Results There were 18 peaks in the UPLC fin-gerprints of raw bupleurum and vinegar bupleurum,and the analysis results showed that there were nine main differences between raw bupleurum and vinegar bupleurum,among which peaks 9,7 and 6 could be considered as bupleurin d,bupleurin a and bupleurin f.The results of spectral effect relationship showed that the main components of bupleurum anti-liver fibrosis were peaks 11,12,14,15 and 18.Conclusions The established fingerprint method of raw bupleurum and vinegar bupleurum is simple and feasible,and the important components of anti-liver fibrosis activity are screened through the spectrum effect relationship,which provides a basis for clarifying the material basis of anti-liver fibrosis effect of raw bupleurum and vine-gar bupleurum.

Aim To evaluate the effect of ricolinostat on X-ray induced myocardial fibrosis and damage to primary cilia in myocardial fibroblasts.Methods Wistar rats were subjected to a single dose of 8 Gy whole-body irradiation,followed by intraperitoneal in-jection of ricolinostat.Serum troponinT(TnT)and brain natriuretic peptide(BNP)levels were measured using ELISA.The degree of myocardial tissue fibrosis was measured using HE and Masson staining.Type Ⅰcollagen and primary cilia were detected using immuno-fluorescence.The gene and protein levels of histone deacetylase 6(HDAC6)in myocardial tissue and cells were detected using PCR and Western blot.Results Compared with the control group,X-ray radiation in-creased type Ⅰ collagen content and promoted the pro-liferation of myocardial fibroblasts in rat myocardial tis-sue.X-ray radiation slightly up-regulated the expres-sion of HDAC6 in myocardial fibroblasts(P＞0.05),and significantly increased the formation of primary cil-ia in myocardial tissue and myocardial fibroblasts.Af-ter treatment with ricolinostat,the expression of HDAC6 and primary cilia formation decreased in myo-cardial tissue and myocardial fibroblasts(P＜0.05),and acetylation in the cytoplasm significantly in-creased.The arrangement of collagen fibers in myocar-dial tissue was slightly neat,collagen volume fraction was reduced,and the levels of TnT(P＜0.01)and BNP decreased.Conclusions Ricolinostat can miti-gate X-ray induced myocardial fibrosis via the disas-sembly of primary cilia,with potential value for trea-ting radiation-induced myocardial fibrosis.

Objective To investigate the changing distribution and antibiotic resistance profiles of clinical isolates of Staphylococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Staphylococcus according to the unified protocol of CHINET(China Antimicrobial Surveillance Network)using disk diffusion method and commercial automated systems.The CHINET antimicrobial resistance surveillance data from 2015 to 2021 were interpreted according to the 2021 CLSI breakpoints and analyzed using WHONET 5.6.Results During the period from 2015 to 2021,a total of 204,771 nonduplicate strains of Staphylococcus were isolated,including 136,731(66.8％)strains of Staphylococcus aureus and 68,040(33.2％)strains of coagulase-negative Staphylococcus(CNS).The proportions of S.aureus isolates and CNS isolates did not show significant change.S.aureus strains were mainly isolated from respiratory specimens(38.9±5.1)％,wound,pus and secretions(33.6±4.2)％,and blood(11.9±1.5)％.The CNS strains were predominantly isolated from blood(73.6±4.2)％,cerebrospinal fluid(12.1±2.5)％,and pleural effusion and ascites(8.4±2.1)％.S.aureus strains were mainly isolated from the patients in ICU(17.0±7.3)％,outpatient and emergency(11.6±1.7)％,and department of surgery(11.2±0.9)％,whereas CNS strains were primarily isolated from the patients in ICU(32.2±9.7)％,outpatient and emergency(12.8±4.7)％,and department of internal medicine(11.2±1.9)％.The prevalence of methicillin-resistant strains was 32.9％in S.aureus(MRSA)and 74.1％in CNS(MRCNS).Over the 7-year period,the prevalence of MRSA decreased from 42.1％to 29.2％,and the prevalence of MRCNS decreased from 82.1％to 68.2％.MRSA showed higher resistance rates to all the antimicrobial agents tested except trimethoprim-sulfamethoxazole than methicillin-susceptible S.aureus(MSSA).Over the 7-year period,MRSA strains showed decreasing resistance rates to gentamicin,rifampicin,and levofloxacin,MRCNS showed decreasing resistance rates to gentamicin,erythromycin,rifampicin,and trimethoprim-sulfamethoxazole,but increasing resistance rate to levofloxacin.No vancomycin-resistant strains were detected.The prevalence of linezolid-resistant MRCNS increased from 0.2％to 2.3％over the 7-year period.Conclusions Staphylococcus remains the major pathogen among gram-positive bacteria.MRSA and MRCNS were still the principal antibiotic-resistant gram-positive bacteria.No S.aureus isolates were found resistant to vancomycin or linezolid,but linezolid-resistant strains have been detected in MRCNS isolates,which is an issue of concern.

As a unique gene in the genome,FLASH(FADD-like interleukin-1β-converting enzyme asso-ciated huge protein)/CASP8AP2 is involved in multiple cellular processes,including apoptosis,histone gene pre-mRNA processing,transcriptional regulation,and cell cycle progression.Clinical studies have shown that FLASH is a valuable prognostic marker for acute lymphoblastic leukemia,and a crucial factor for the survival of various cancer cells.Therefore,in-depth research into the function of FLASH may offer new perspectives for the treatment of related diseases.Our previous research identified FLASH as a bind-ing partner of p53,demonstrating that FLASH enhances the transcriptional activity of p53.Here we fur-ther investigate the molecular mechanisms of the interaction between FLASH and p53,revealing that the p53-K386R mutation(SUMOylation residue)attenuated its interaction with FLASH(aa 51-200)and FLASH-SIM(SUMO-interacting motif)(aa 1 534-1 806)significantly.However,SUMO can bind to FLASH-SIM directly,instead of FLASH(aa 51-200).Subsequent research shows that overexpression of FLASH in cells enhances global SUMO1 conjugation and p53-SUMO1 conjugation,therefore providing a plausible explanation for the underlying mechanism of FLASH enhancing the transcriptional activity of p53.Since promyelocytic leukemia protein nuclear body(PML NB)serves as subcellular reactors for SUMO conjugation within the cell,and the PML Ⅳ isoform can specifically enhance the SUMO modifica-tion of p53,we have investigated the interaction between FLASH and PML Ⅳ,and elucidated the struc-tural basis of their interaction:both FLASH-N3A(501-802)and FLASH-C2(1 807-1 981)bind to PML Ⅳ(aa 228-633).Further investigations reveal that they can synergistically enhance global SUMO1 modification as well as SUMO1 modification of p53.The interaction between FLASH and tumor suppres-sors p53 or PML Ⅳ enriches our understanding of its function and reveals the potential mechanism of FLASH in tumor development,therefore offering novel insights into cancer diagnosis and treatment.

Objective:To analyze the efficacy and influencing factors of cyclosporine(CsA)alone in the treatment of children with acquired aplastic anemia(AA).Methods:The clinical data of children diagnosed with AA and treated with CsA alone from January 1,2016 to December 31,2020 in the Children's Hospital of Chongqing Medical University were collected,and the efficacy and influencing factors of CsA treatment were evaluated.Results:Among the 119 patients,there were 62 male and 57 female,with a median age of 7 years and 1 month.There were 45 cases of very severe AA(VSAA),47 cases of severe AA(SAA),and 27 cases of non-severe AA(NSAA).At 6 months after treatment,the efficacy of VSAA was lower than that of SAA and NSAA,and there was a statistical difference(P＜0.01).6 cases died early,16 cases relapsed,2 cases progressed to AML and ALL.The results of univariate analysis showed that the high proportion of lymphocyte in the bone marrow at 6 months was an adverse factor for the efficacy of CsA,while high PLT count was a protective factor(P=0.008,P=0.002).The ROC curve showed that the cut-off values of PLT count and the proportion of bone marrow lymphocyte at 6 months were 16.5 × 109/L,68.5％,respectively.Multivariate analysis showed that the high proportion of lymphocyte in bone marrow at 6 months was an independent adverse factor for IST(P=0.020,OR=0.062),and high PLT count was a protective factor(P=0.044,OR=1.038).At 3 months of treatment,CsA response and NSAA were the risk factor for recurrence(P=0.001,0.031).Conclusion:The efficacy of NSAA was higher than that of SAA and VSAA after 6 months of treatment with CsA alone.A high PLT count at the initial diagnosis was a good factor for the effectiveness of CsA,and a high proportion of bone marrow lymphocyte was an unfavorable factor.CsA response at 3 months and NSAA were risk factors for recurrence.

Objective To investigate the status quo and its influencing factors of nurses'organizational silence in 3 Grade A general hospitals.Methods Convenient sampling method was used to investigate clinical nurses in 3 Grade A general hospitals in Xi'an from April to August 2023 by general data questionnaire,nurses'organizational silence questionnaire and hospital magnetic factor scale.Multiple linear regression was used to analyze the influencing factors of organizational silence.Results A total of 855 nurses completed the study.The total silence score of nurses was(56.33±8.55);The total score of hospital magnetic level was(107.63±12.85).There was a negative correlation between nurse tissue silence and hospital magnetic level(r=-0.318,P<0.01).Hospital magnetic level,age,job title and working time were the influential factors of nurses'organizational silence(all P<0.001),which together explained 62.60%of the variation.Conclusions The silence of nurses'tissue and the level of hospital magnetism are in the low-medium level.Nurses are younger in age,lower in professional title,shorter in nursing age and lower in hospital magnetism level,the higher the tissue age level is,the nursing managers can reduce the tissue silence of nurses by improving the hospital magnetism level.

Objective This paper intends to compare the efficacy and safety of high-dose dual regimens containing Vonoprazan and proton pump inhibitor in patients infected with Helicobacter pylori(H.pylori).Methods A prospective randomized controlled study was conducted.According to inclusion and exclusion criteria.,243 patients with H.pylori infection admitted to the Department of Gastroenterology,the First Hospital of Lanzhou University from February 2023 to December 2023 were enrolled as the research objects.They were randomly divided into two groups.The high-dose dual therapy containing Vonoprazan group(VPZ-HDDT group)was given Vonoprazan fumarate tablet 20mg twice daily plus amoxicillin 750 mg four times daily for 14 days and the high-dose combination group containing PPI(PPI-HDDT group)was given esomeprazole 40 mg twice daily plus amoxicillin 750 mg four times daily for 14 days.Patients were followed up and recorded by telephone or WeChat on the 7th and 14th day of starting treatment for drug intake and occurrence of adverse reactions.Patients were instructed to recheck the 13C or 14C urea breath test at least 1 month after the end of medication.Treatment by protocol(PP)analysis,modified intention to treat(mITT)and intention-to-treat(ITT)analysis were used for H.pylori eradication rates in both groups,and compliance and incidence of adverse reactions were compared between the two groups.Results The eradication rates of the VPZ-HDDT group and the PPI-HDDT group in the initial treatment were 94.0％and 88.5％(P=0.209)by PP analysis,and 91.8％and 87.5％(P=0.358)86.7％by mITT analysis,and 81.9％(P=0.377)by ITT analysis,respectively.In the retreated patients,the PP analysis and mITT analysis eradication rates in these two groups were consistent,87.0％and 84.2％(P=0.800),respectively,and 83.3％and 76.2％(P=0.550)by ITT analysis.For the refractory H.pylori patients,the PP analysis and mITT analysis eradication rates in these two groups were also consistent,71.4％and 50.0％(P=0.429),and the eradication rates of ITT analysis were 62.5％and 50.0％(P=0.640),respectively.In different stratifications,the eradication rates of the VPZ-HDDT group were higher than those of the PPI-HDDT group,but the differences were not statistically significant.The incidence of adverse reactions and compliance of the VPZ-HDDT group and the PPI-HDDT group were similar,with no statistically significant differences.Conclusion Both two combination regimens can achieve clinically acceptable eradication rates(＞85％)in the first-time treatment patients.For the retreated and refractory patients,the choice of vonoprazan is more beneficial.

Objective:To explore the effects of hierarchical and regional management based on multi-department as-sistance on first-aid efficiency and rescue effect in patients with acute myocardial infarction(AMI).Methods:A total of 55 AMI patients who were treated in Emergency Department of Nuclear Industry 416 Hospital between Jan-uary and June 2021 were retrospectively enrolled as routine management group,another 67 AMI patients treated in our Emergency Department between January and June 2022 were enrolled as hierarchical and regional management group.First-aid efficiency related indexes,rescue time,hospital stay,rescue success rate related indexes and prog-nosis were compared between two groups.Results:Compared with routine management group,there were signifi-cant reductions in door-to-balloon time[(55.39±5.86)min vs.(31.47±5.41)min],passage residence time[(68.16±5.82)min vs.(51.17±5.06)min],emergency room stay time[(21.83±3.07)min vs.(13.04±2.75)min],venous channel open time[(5.03±1.62)min vs.(3.34±1.21)min],waiting time[(91.66±5.34)min vs.(70.15±4.33)min],rescue time[(55.15±7.34)min vs.(25.71±5.80)min],symptom relieving time[(66.74±9.02)h vs.(46.13±8.23)h]and hospital stay[(7.58±2.16)d vs.(5.02±1.35)d]in hierarchical and regional management group(P＜0.001 all).Total satisfaction of rescue(88.06％vs.70.91％)and rescue suc-cess rate(95.52％vs.76.36％)of hierarchical and regional management group were significantly higher than those of routine management group,and total incidence rate of adverse cardiovascular events(10.45％vs.25.45％)was significantly lower than that of routine management group(P＜0.05 or＜0.01).Conclusion:The hierarchical and regional management based on multi-department assistance can significantly improve first-aid efficiency and res-cue effect in patients with acute myocardial infarction,the rescue success rate is high and prognosis is good.
