Narrative is the cornerstone of interpersonal relationships and life safety. However， its important value in daily life， school education， health management， personal happiness， career development， and other aspects has been ignored. The narrative ecology of families， schools， hospitals， workplaces， and elderly care institutions is worrying， the narrative connection between parent-child and intergenerational is broken， the narrative nature of adolescents is ignored， the narrative demands of patients are neglected， narrative relationships in the workplace are indifferent， and the narrative capital of the elderly is idle. These issues have resulted in serious social problems， such as depression and suicide among adolescents， conflicts between doctors and patients， workplace and life burnout among middle-aged people， and the inability of the elderly to achieve healthy aging， which have become a “stumbling block” to the realization of holistic health. Advocating the construction of narrative ecology and interpersonal narrative connections is an important measure of achieving holistic health. Taking the “narrative concept” as the overall framework， and based on the research， education， and practice carried out by the Alliance of Narrative Medicine in Higher Education Institutions， this paper proposed that actively build China’s narrative system of life and health， to enable narrative play an active and dynamic role in the construction of narrative ecology in different spaces， such as the families， the schools， the hospitals， the workplaces， and the elderly care institutions， as well as practically improve the quality of life of the people.

Objective:To investigate the impact of BMI1 expression in OSCC on the recruitment and differentiation of tumor-associat-ed macrophages(TAMs).Methods:BMI1 expression in 519 cases of OSCC tissues and 44 normal controls was analyzed using online datasets of GEPIA 2.0,and validated in 3 cases of OSCC samples and controls by qRT-PCR and western blotting.The function of BMI1/NF-κB axis during OSCC carcinogenesis was investigated by CCK8 assays,wound healing test and transwell assays.Macrophage phenotypes and recruitment were determined using qRT-PCR and western blotting following coculture of the cells with human monocyte cells(THP-1)by OSCC conditioned medium.Moreover,a cell line-derived xenograft(CDX)model was used to detect the effect of BMI1 on tumor growth in vivo.Results:Compared with the normal tissues and cells,the expression level of BMI1 in OSCC tissues and cells was significantly upregulated.BMI1 knockdown impaired the proliferation,migration,and invasion abilities of OSCC cell lines in NF-κB-dependent manner.Furthermore,OSCC cells with high BMI1 expression inhibited the migration of THP-1 cells,promoted M2-like macrophage polarization through NF-κB pathway in vitro.Xenograft experiments further confirmed the inhibitory effect of BMI1 knockdown on the tumorigenesis ability of OSCC cells in vivo.Conclusion:BMI1 promotes M2-like polarization by regulating NF-κB and may be used as a potential therapeutic target for antitumor immunity.

Objective To explore the prognostic value of hs-cTnⅠ in patients with suspected acute coronary syndrome(ACS)in emergency department.Methods A large-scale,prospective observa-tional study was conducted on totally 966 patients with suspected ACS admitted in Fuwai Hospi-tal from January 2017 to October 2020.Their baseline serum/plasma hs-cTnⅠ level was detected at admission,conventional treatment was performed,and relevant data were collected.Logistic regression analysis was used to predict the risk of primary and secondary endpoint events within 30 d by hs-TnⅠ concentration,and subgroup analysis was performed.Results Among the 966 patients,the time from chest pain to visit was 5.0(2.5,13.0)h,and 284 patients had primary end-point events within 30 d,including 283 cases of myocardial infarction(99.6％)at the first visit,1 case of recurrent myocardial infarction(0.4％),5 cases of cardiovascular death(1.8％),and 1 case of unplanned revascularization(0.4％).When hs-cTnⅠ was at the minimum detection limit of 2 ng/L,the incidence of adverse events was 5.8％,when the limit of 70 ng/L,the incidence was 49.2％,and when of 316 ng/L,the incidence reached 100％.The model could correctly classify 92.3％of the patients.Conclusion The hs-cTn sequence has a good predictive effect for the risk of short-term cardiovascular adverse events in Chinese population.

Objective:To investigate the genomic profiles and immune microenvironment of olfactory neuroblastoma (ONB).Methods:Nineteen ONB cases diagnosed in the Beijing Tongren Hospital from May 2018 to October 2022 were divided into low-grade and high-grade groups according to the Hyams grading system, including 7 low-grade and 12 high-grade ONB. Whole exome sequencing and multiplex immunofluorescence analyses were performed on tissue samples of these ONB.Results:A total of 929 nonsynonymous alterations were identified in 18 of the 19 ONB (18/19) cases. The most commonly altered cancer-related genes were CTNNB1 (3/19) and ZNRF3 (3/19). The most mutated oncogenic pathways were the WNT and RAS pathways. The median tumor mutation burden (TMB) was 0.45/Mb, ranging from 0 to 3.25. The median tumor neoantigen load (TNB) was 9.39 neoantigens/Mb, ranging from 0 to 38.30. The median allelic mutation tumor heterogeneity (MATH) score was 16.95, ranging from 3.05 to 117.47. Only one of the 19 cases expressed PD-L1 (composite positive score, CPS>1) in the tumor cells. The median percentage of CD8 + tumor-infiltrating lymphocyte (TIL) in the tumor region was 1.08%. No significant differences were observed between the low-and high-grade groups for mutant genes, mutant pathways, TMB, TNB, MATH, PD-L1 expression levels, or CD8 + TILs percentage( P>0.05). However, the low-grade group showed significantly more CD68 + macrophages in both the tumor and total region than the high-grade group. Notably, CD68 +CD163 - macrophages accounted for an average of 80.52% of CD68 + macrophages. Conclusions:CTNNB1 and ZNRF3 are the most commonly altered cancer-related genes. The low expression of PD-L1 and the low percentage of CD8 + TIL indicate that ONB might not be sensitive to immunotherapy. The percentage of M1-type macrophages in low-grade ONB is significantly higher than that in high-grade ONB, suggesting that M1-type macrophages may be involved in the progression of ONB from low-grade to high-grade.

Objectives:To compare the diagnostic efficacy of non-ST-segment elevation myocardial infarction (NSTEMI) and the predictive value for major adverse cardiovascular events (MACE) of the 0/3-hour algorithm for high-sensitivity cardiac troponin (hs-cTn) recommended by the 2015 European Society of Cardiology (ESC) guidelines for the management of non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and the 2021 "Chinese Expert Consensus on Laboratory Testing and Clinical Application of Cardiac Troponin" in suspected acute coronary syndrome (ACS) patients in the Chinese population. Methods:This is a multicenter prospective observational study,including 1527 patients with suspected ACS from three clinical centers from January 2017 to September 2020.Plasma hs-cTnI levels were measured using the ARCHITECT assay at the time of presentation and 3 hours later in patients with suspected ACS (test determination).Clinical judgment (independent clinical judgment by cardiac experts,independent of the test results) was used as the gold standard to compare the sensitivity,specificity,and consistency of the two diagnostic algorithms,and to analyze their predictive value for MACE at 30 days and 180 days.MACE in this study was defined as a composite event of cardiovascular death,myocardial infarction,and unplanned coronary revascularization. Results:According to clinical judgment,there were 400 patients with NSTEMI and 1127 patients without NSTEMI.The 0/3-hour algorithm recommended by the 2021 Chinese Expert Consensus showed higher sensitivity in diagnosing NSTEMI than the 2015 ESC guidelines (91.50％[95％ CI:88.32％-94.04％]vs.87.75％[95％ CI:84.13％-90.80％]),but slightly lower specificity (93.88％[95％ CI:92.32％-95.21％]vs.95.56％[95％ CI:94.19％-96.69％]),with both differences being statistically significant (both P<0.001).In the follow-up at 30 days and 180 days,the incidence of MACE in patients diagnosed with NSTEMI by both algorithms was higher than in those without NSTEMI (P<0.001).The incidence of MACE at 30 days and 180 days for the group excluded from the diagnosis of NSTEMI by 2015 ESC guidelines was 0.19％ and 1.120％,respectively,and for the NSTEMI group was 2.89％ and 3.68％,respectively;for the group excluded from NSTEMI by the 2021 Chinese Expert Consensus,the incidence was 0.096％ and 0.770％,respectively,and for the NSTEMI group was 2.91％ and 4.36％,respectively.Cox analysis showed that the HR ratio for MACE at 180 days in the NSTEMI group diagnosed by both algorithms was 3.418 and 5.892,respectively,significantly higher than the group excluded from NSTEMI. Conclusions:The 0/3-hour algorithm recommended by the 2021 Chinese Expert Consensus has superior diagnostic sensitivity compared to the 2015 ESC NSTE-ACS guidelines,at the cost of slightly lower specificity.Both algorithms can effectively predict MACE within 180 days,but based on the data from this study,the algorithm recommended by the 2021 Chinese Expert Consensus is more sensitive in predicting the risk of MACE,and patients excluded from the diagnosis of NSTEMI by this method have a lower incidence of MACE,suggesting that its application in clinical practice may be more helpful in terms of long-term safe management of patients.

Objective:This study aims to demonstrate the feasibility of using Bio-layer Interferometry (BLI) for label-free detection of peripheral blood biomarkers, using C-reactive protein (CRP) as a model molecule.Methods:A total of 85 clinical remnant serum samples from routine laboratory tests were collected from Fuwai Hospital, Chinese Academy of Medical Sciences, from July 2021 to May 2022. The biotinylated anti-CRP antibody was immobilized onto streptavidin-functionalized BLI probes. The GatorPrime BLI system was used to detect series of diluted CRP standards in real-time, and to generate dynamic binding curves for establishing standard curves based on the relationship between concentration and initial binding rates. The sensitivity of the method, including the limit of blank (LoB), limit of detection (LoD), and limit of quantitation (LoQ), was evaluated according to Clinical & Laboratory Standards Institute (CLSI) guidelines. Serum samples and third-party quality control materials were used to evaluate the precision, while linearity was verified through the dilution of a high-concentration serum series. Method comparison between the label-free BLI assay and conventional clinical laboratory immunoassays was conducted using Passing-Bablok regression and Spearman correlation analysis.Results:The GatorPrime BLI system demonstrated a dynamic detection range of 0.6-300 mg/L for CRP standards, and the linearity within this range was validated using serum samples. The LoB, LoD, and LoQ for this method were determined to be 0.246 mg/L, 0.573 mg/L, and 2.158 mg/L, respectively. Precision analysis showed that the total laboratory imprecision of the four levels of quality control materials (21.15-57.26 mg/L) ranged from 5.8% to 9.0%, and the total imprecision of the two serum samples (2.32 mg/L and 100.06 mg/L) was 22.3% and 7.4%, respectively. Methodological comparison with two commonly used clinical laboratory immunoassays revealed a strong correlation with our method(Passing-Bablok regression: Y=?1.065+1.119 X and Y=?0.452+1.034 X, r=0.993 and r=0.976, P<0.001). Conclusions:The label-free BLI immunoassay method enables the detection of CRP across a broad concentration range in blood samples, with analytical performance meeting the requirements for laboratory testing. This method shows potential as a reliable and efficient alternative for CRP measurement in clinical practice.

Background There is a lack of research evidence on the association between sugar-sweetened beverage (SSB) consumption and gestational diabetes mellitus (GDM) in China. Objective To explore the association between frequency of SSB consumption before pregnancy and risk of GDM in pregnant women in Shaanxi Province, and to provide a scientific basis for targeted interventions to control maternal blood glucose. Methods The recruitment to the China Birth Cohort study started in October 2020. Pregnant women at 6-16 weeks who had their first prenatal examination at five hospitals in Shaanxi Province were recruited. A maternal health questionnaire was used to collect basic information about pregnant women. A semi-quantitative food frequency questionnaire was used to collect the consumption of carbonated beverages, fruit and vegetable juice beverages, coffee beverages, and milk tea beverages in one year before pregnancy, which were summed to obtain the SSB consumption. Pregnant women were divided into three groups according to SSB consumption, namely <1 serving·week⁻¹, 1-4 servings·week⁻¹, and ≥5 servings·week⁻¹. GDM was confirmed by oral glucose tolerance test (OGTT) between 24-28 weeks of gestation. A binary logistic regression model was applied to explore the association between SSB consumption and risk of GDM. Multiple linear regression was applied to investigate the associations between SSB consumption (per 1-serving·d⁻¹ increase) and OGTT fasting plasma glucose, 1-hour glucose, and 2-hour glucose. Results A total of 3811 pregnant women were finally enrolled in this study, of which 752 developed GDM, with an incidence rate of 19.7%. The incidence rates of GDM in pregnant women with SSB consumption frequency of <1 serving·week⁻¹, 1-4 servings·week⁻¹, and ≥5 servings·week⁻¹ were 18.0%, 21.1%, and 26.8%, respectively. After adjusting for maternal age, pre-pregnancy body mass index (BMI), education, number of children born, family history of diabetes, smoking, alcohol consumption, physical activity level, and total energy intake, the risk of GDM increased by 26% (OR=1.26, 95%CI: 1.05, 1.50) in the 1-4 servings·week⁻¹ group and by 76% (OR=1.76, 95%CI: 1.31, 2.38) in the ≥5 servings·week⁻¹ group compared to the <1 serving·week⁻¹ SSB consumption group, respectively. Further stratified analysis revealed no interaction effect (P_interaction>0.05) between SSB consumption and maternal age, pre-pregnancy BMI, or first labor or not. For each additional SSB consumption per day, the risk of GDM increased by 94% (OR=1.94, 95%CI: 1.37, 2.75); and the maternal OGTT 1-hour glucose and 2-hour glucose increased by 0.33 mmol·L⁻¹ and 0.18 mmol·L⁻¹, respectively (P<0.05), and no significant increase in fasting plasma glucose was found (P>0.05). Conclusion Higher SSB consumption before pregnancy increases the risk of GDM in pregnant women.

Objective:To explore the consistency between modified 12+ X prostate biopsy under transrectal interventional ultrasound and postoperative Gleason score in prostate cancer patients.Methods:A retrospective study was conducted on 312 patients diagnosed with prostate cancer and underwent radical resection at Zhongshan People′s Hospital from January 2020 to December 2022. All patients underwent modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound before surgery. Using the Gleason score of postoperative pathological specimens as the " gold standard", the detection rates of prostate cancer and clinically significant prostate cancer using modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound were compared, and the consistency between the two methods alone or in combination and postoperative Gleason score was compared.Results:Among 312 patients, the positive detection rate of the improved 12+ X puncture biopsy combined with the system puncture biopsy was significantly higher than that of the individual detection (95.51% vs 80.77% vs 76.92%), with a statistically significant difference ( P<0.05). The improved 12+ X puncture biopsy combined with system puncture biopsy showed a clinically significant higher detection rate of prostate cancer in positive patients compared to the two tests alone (94.63% vs 77.78% vs 80.00%), with a statistically significant difference ( P<0.05). There was no statistically significant difference in the detection rate of clinically significant prostate cancer among patients who missed diagnosis, either alone or in combination with biopsy ( P>0.05). The upgrade rate of Gleason score after prostate improvement 12+ X puncture biopsy (25.00%) was significantly lower than that of prostate system puncture (44.17%), which was significantly higher than combined puncture biopsy (11.74%), with a statistically significant difference ( P<0.05). After 312 patients received combined puncture biopsy, urinary retention was found in 14 cases (4.49%), hematuria in 30 cases (9.62%), fever in 28 cases (8.97%), and blood in stool in 18 cases (5.77%). After symptomatic treatment, they basically improved within 3 days after puncture. Conclusions:The combination of modified 12+ X prostate biopsy with systematic biopsy under transrectal interventional ultrasound can improve the detection rate of prostate cancer, and has good consistency with the postoperative Gleason score of prostate cancer patients, which has good clinical application value.

Objective:To investigate the effects and mechanisms of copper transporter 1 (CTR1) in radiation induced intestinal injury in vitro. Methods:Human small intestinal epithelial cells (HIEC) were irradiated with 2, 4, 6, 8 Gy of X-rays and rat intestinal epithelial cells (IEC-6) were irradiated with 5, 10, 15, 20 Gy of X-rays. At 2, 4, 8, 24, and 48 h after irradiation, the expression of CTR1 was detected by Western blot assay. In some experiments, HIEC and IEC-6 cells were transfected with CTR1 shRNA and then exposed to X-rays. Copper levels were detected by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The radiosensitivity of cells was verified by colonogenic assay, the cellular reactive oxygen species (ROS) level and DNA damage were detected to further explore the related mechanism. In addition, Western blot was applied to detect the expressions of antioxidants and cuproptosis associated proteins in enterocytes after silencing CTR1 or irradiation.Results:The expression of CTR1 was increased by X-ray irradiation in a dose-dependent manner ( t=3.53, 3.45, 6.37, 11.11, 11.13, P<0.05). CTR1 expression was successfully diminished by CTR1 shRNA adenovirus vectors. According to the survival curves, the enhancement ratios of the radiosensitivity of HIEC and IEC-6 cells with CTR1 knocking-down were 1.146 and 1.201, respectively. Radiation-induced copper accumulation was alleviated after CTR1 silencing in IEC-6 cells ( t=3.10, P<0.05). At 0.5 h after irradiation, the ROS production in the CTR1 knockdown group was significantly lower than that in the control group ( t=5.23, 2.96, P<0.05). At 1 h after irradiation, the protein expression of γ-H2AX in the CTR1 knockdown group was obviously lower than that in the control group ( t=7.50, 4.29, P<0.05). The expressions of Nrf2 and HO-1 were increased after irradiation, which could be further increased after CTR1 silencing. In addition, cuproptosis associated protein DLAT, LIAS and FDX1 were reduced post-irradiation, which were recovered after CTR1 silencing. Conclusions:The radioresistance of HIEC and IEC-6 cells was enhanced after CTR1 silencing, possibly through the intracellular ROS and cuproptosis pathway.
