In the era of evidence-based medicine， the progress of medical science and technology has enriched medical diagnostic tools and treatment methods， but it has also led to the loss of medical warmth and the alienation of the doctor-patient relationships. William Osler emphasized that while medical technology advances， attention should also be paid to the practice of narrative medicine and the development of physician’s narrative literacy. The view of the physician he advocated reminds us that the core of medicine still lies in the narrative connection between doctors and patients， as well as a deep understanding of human nature. By exploring the relationship between Osler’s view of the physician and narrative medicine as well as physician’s narrative literacy， this paper analyzed the methods of cultivating physician’s narrative literacy， providing references for modern medical education and practice， and assisting in the harmony and unity of science and technology and humanity.

Purpose To evaluate the diagnostic value of three-dimensional amide proton transfer weighted imaging(APTWI)in distinguishing benign from malignant bone tumors and the diagnostic efficacy of APTWI combined with diffusion-weighted imaging(DWI).Materials and Methods Sixty-nine patients with pelvic and lower extremity bone tumors,confirmed by puncture or surgical pathology at the First Affiliated Hospital of Zhengzhou University,were prospectively collected from April 2022 to July 2023.On the relevant parameter maps of APTWI and DWI,the asymmetric magnetization transfer rate at a chemical shift of 3.5 ppm[MTRasym(3.5 ppm)]and apparent diffusion coefficient(ADC)values corresponding to the lesions were measured,respectively.Comparative analysis of differences in each parameter was conducted,and the diagnostic efficacy of these parameters alone and in combination was compared.Results Among 69 bone tumor,24 were benign cases and 45 malignant cases.MTRasym(3.5 ppm)of malignant bone tumors was higher than that of benign tumors[(2.974±0.630)%vs.(2.215±0.963)%],while ADC values of malignant bone tumors were lower than those of benign tumors[(1.143±0.406)×10-3 s/mm2 vs.(1.757±0.449)×10-3 s/mm2],with significant differences between the two groups(t=3.532,-5.645;P<0.001).Receiver operating characteristic curve showed that MTRasym(3.5 ppm),ADC values,and their combination exhibited good performance in the differential diagnosis of benign and malignant bone tumors,with the area under the curve being 0.765,0.841 and 0.874,respectively.There were no statistically significant differences in the area under the curve between the combined APTWI-DWI and either APTWI or DWI alone in diagnosing benign and malignant bone tumors(combined vs.APTWI:Z=1.873,P=0.064;combined vs.DWI:Z=1.333,P=0.167).The diagnostic specificity of combined APTWI-DWI was significantly higher than that of APTWI alone(96%vs.56%,P=0.001),but there was no statistically significant difference compared with DWI alone(96%vs.80%,P=0.189).Conclusion APTWI and DWI,either alone or in combination,could serve as effective imaging indicators for distinguishing benign from malignant bone tumors.The combination of APTWI and DWI shows a trend of achieving higher diagnostic efficacy and diagnostic specificity in differentiating benign from malignant bone tumors,thus holding potential clinical application value.

ObjectiveTo evaluate the effect of Suanzaoren Tang on the rat model of depression established by solitary culture combined with chronic unpredictable mild stress by reshaping the inflammatory microenvironment and mediating changes in hippocampal synaptic plasticity. MethodsSeventy-two male SD rats were randomized by a random number table into six groups： control group， model group， fluoxetine group （0.003 6 g·kg^-1）， and high-（10 g·kg^-1）， medium-（5 g·kg^-1）， low-dose （2.5 g·kg^-1）Suanzaoren Tang groups， with 12 rats per group. The sucrose preference rate and open field test scores of rats in each group were observed. Western blot was employed to determine the expression levels of the key proteins in the specificity protein 1 （SP1）/sphingosine kinase 1 （SK1）/sphingosine-1-phosphate receptor 1 （S1PR1） signaling pathway， as well as hippocampal proteins synaptophysin Ⅰ （SYNⅠ）， postsynaptic density protein-95 （PSD-95）， and family with sequence similarity 19， member A5 （FAM19A5）. Immunohistochemistry was employed to detect the positive expression of SP1， PSD-95， SYNⅠ， interleukin （IL）-10， and IL-6. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA levels of SP1 and S1PR1. Finally， transmission electron microscopy was employed to observe the ultrastructural changes of hippocampal synapses. ResultsCompared with the control group， the model group exhibited a decrease in sucrose preference index （P<0.01） and reduced total scores for horizontal and vertical movements in the open field test （P<0.01）， which indicated the successful modeling of depression. Moreover， the model group showed reduced synaptic vesicles in the hippocampus （P<0.01）， up-regulated expression of SP1， SK1， S1PR1， and IL-6 （P<0.01）， and down-regulated expression of SYNⅠ， PSD-95， FAM19A5， and IL-10 （P<0.01）. Compared with the model group， high- and medium-dose Suanzaoren Tang and fluoxetine increased the sucrose preference index and the total scores for horizontal and vertical movements in the open field test （P<0.01）. All Suanzaoren Tang groups and the fluoxetine group demonstrated reductions in SP1， SK1， S1PR1， and IL-6 expression （P<0.05， P<0.01）， alongside restored synaptic vesicles in the hippocampus （P<0.05， P<0.01）. ConclusionSuanzaoren Tang modulates hippocampal expression of FAM19A5， SYNⅠ， PSD-95， IL-10， IL-6， and the SP1/SK1/S1PR1 pathway in the rat model of depression. The antidepressant effects may be related to the ability of reducing neuroinflammation and enhancing synaptic plasticity.

Pancreatic cancer is among the most malignant cancers,and thus early intervention is the key to better survival outcomes.However,no methods have been derived that can reliably identify early precursors of development into malignancy.Therefore,it is urgent to discover early molecular changes during pancreatic tumorigenesis.As aberrant glycosylation is closely associated with cancer progression,numerous efforts have been made to mine glycosylation changes as biomarkers for diagnosis;however,detailed glycoproteomic information,especially site-specific N-glycosylation changes in pancreatic cancer with and without drug treatment,needs to be further explored.Herein,we used comprehensive solid-phase chemoenzymatic glycoproteomics to analyze glycans,glycosites,and intact glycopeptides in pancreatic cancer cells and patient sera.The profiling of N-glycans in cancer cells revealed an increase in the secreted glycoproteins from the primary tumor of MIA PaCa-2 cells,whereas human sera,which contain many secreted glycoproteins,had significant changes of glycans at their specific glycosites.These results indicated the potential role for tumor-specific glycosylation as disease biomarkers.We also found that AMG-510,a small molecule inhibitor against Kirsten rat sarcoma viral oncogene homolog(KRAS)G12C mutation,profoundly reduced the glycosylation level in MIA PaCa-2 cells,suggesting that KRAS plays a role in the cellular glycosylation process,and thus glycosylation inhibition contributes to the anti-tumor effect of AMG-510.

Objective To explore the value of 3D amide proton transfer weighted imaging(APTWI),diffusion weighted imaging(DWI)and the combination for differentiating benign and malignant bone and soft tissue tumors.Methods Non-contrast MRI,APTWI and DWI of pelvis or lower extremity were prospectively acquired in 96 patients with bone and soft tissue tumors.MTRasym and ADC maps were obtained based on APTWI and DWI calculation with an offset of 3.5 ppm,respectively,and the maximum asymmetric magnetization transfer rate(MTRasym)(MTRasymmax),the mean MTRasym(MTRasymmean)and the minimum MTRasym(MTRasymmin),as well as the maximum apparent diffusion coefficient(ADC)(ADCmax),the mean ADC(ADCmean)and the minimum ADC(ADCmin)values were measured.The above parameters were compared between benign and malignant tumors.Then receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficacy of APTWI,DWI and the combination.Results Among 96 patients,there were 41 benign and 55 malignant pelvic or lower limb bone and soft tissue tumors.In benign tumors,MTRasym(3.5 ppm)values,including MTRasymmax.MTRasymmean and MTRasymmin were significantly higher,whereas ADC values including ADCmax,ADCmeanand ADCmin were significantly lower than those in malignant tumors(all P＜0.05).AUC of MTRasymmax and ADCmin for differentiating benign and malignant bone and soft tissue tumors was 0.791 and 0.873,respectively,being not statistically different(P=0.122),but both lower than that of their combination(AUC=0.944,P＜0.001,P=0.041).Conclusion APTWI combined with DWI had high efficacy for differentiating benign and malignant bone and soft tissue tumors.

Objective:To analyze the reinfection rates in people previously infected with SARS-CoV-2 in Zhengzhou and Yuzhou cities (first infected with Delta/B.1.617.2 variant), and Anyang city (first infected with Omicron/BA.1.1 variant) in January 2022 and the population characteristics, and compare the differences in antibody levels among different populations.Methods:Serum samples were collected from 371 previously infected, 134 reinfected and 19 uninfected people for IgG antibody detection. Among them, serum samples from 45 previously infected, 44 reinfected and 19 uninfected people were tested with different novel coronavirus variants (early original strain, BA.5.2 variant, XBB.1.5 variant) for neutralizing antibody detection.Results:The rate of reinfection was 32.82% (85/259) in Zhengzhou and Yuzhou cities, and 19.92% (49/246) in Anyang city. The IgG antibody level in reinfected people was higher than that in previously infected and uninfected people ( P<0.05). The IgG antibody level in uninfected group was higher in people vaccinated within three months than in those vaccinated six months ago ( P<0.05). The IgG antibody level in the group receiving four doses of vaccine was higher than that in the group receiving three doses of vaccine ( P<0.05). The results of true virus neutralization antibody detection showed that in the Zhengzhou and Yuzhou cases, the level of neutralization antibody against the early original strain was higher than those against the BA.5.2 variant and the XBB.1.5 variant ( P<0.05), and the level of neutralizing antibody against BA.5.2 variant was higher than that against XBB.1.5 variant ( P<0.05). In Anyang city cases, the level of neutralizing antibody against the early original strain was higher than those against BA.5.2 variant and XBB.1.5 variant ( P<0.05); in the reinfected population, the level of neutralizing antibody against the early original strain was higher than that against the XBB.1.5 variant ( P<0.05). In addition, the levels of all neutralizing antibodies in both previously infected and reinfected people were higher than those in uninfected people ( P<0.05). The level of neutralizing antibody in the infected population in Zhengzhou and Yuzhou cities was higher than that in the infected population in Anyang city and in uninfected population ( P<0.05). The levels of antibodies against BA.5.2 and anti-XBB.1.5 variants in infected people in Zhengzhou and Yuzhou cities were higher than those in uninfected people ( P<0.05). The level of neutralizing antibody against BA.5.2 variants in the previously infected population in Anyang city was higher than that in the uninfected population ( P<0.05), and the level of neutralizing antibody against XBB.1.5 variants in the infected population in Anyang city was higher than that in the uninfected population ( P<0.05). Conclusions:After infection with SARS-CoV-2, the neutralizing antibodies produced in the human body have a certain cross-protection effect on other variants, but the antibody level will gradually decrease over time. Protection from a previous early SARS-CoV-2 variants infection against the current main circulating Omicron variants (such as XBB variants) is low, and the immunity conferred by pervious infection or booster vaccination may not be able to provide sufficient protection against new variants.
