Patients with sudden deafness encounter greater psychological challenges and communication barriers after experiencing sudden hearing loss， and traditional medical models often fail to adequately address their unique needs. This paper analyzed the current situation of emotional and behavioral changes in patients with sudden deafness， and the gap between their expectations and the reality of medical care. From the perspective of narrative medicine， the theory and characteristics of the reconstruction of the doctor-patient relationships in patients with sudden deafness were explored. The results showed that narrative medicine can enhance patients’ emotional resonance and understanding， improve the efficiency and quality of doctor-patient communication， promote the formulation of personalized treatment plans， and enhance treatment adherence and satisfaction. Based on these results， strategies and pathways for the reconstruction of doctor-patient relationships for patients with sudden deafness were proposed， including building empathetic bridges and tapping into mechanisms of emotional resonance within narrative medicine； optimizing communication strategies and promoting the application of narrative techniques in doctor-patient dialogues； connecting narrative pathways and advocating the exploration of stories and strategies in personalized treatments； as well as facilitating treatment adherence and making full use of the psychodynamic effects of narrative medicine. Narrative medicine， as a patient-centered medical practice， can effectively promote the reconstruction of doctor-patient relationships， enhance treatment effectiveness， and offer a more humane treatment experience for patients.

【Objective】 To explore the clinicopathological characteristics and comprehensive treatment strategies of prostate mucosa adenocarcinoma under multidisciplinary diagnosis and treatment (MDT) mode. 【Methods】 Data of two patients with typical prostate mucosa adenocarcinoma treated in our hospital during Sep.2020 and Apr.2023 were retrospectively analyzed. 【Results】 In case 1, the clinical manifestation was macroscopic hematuria; multiparametric magnetic resonance imaging (mpMRI) indicated solid prostatic nodules, clinical stage T4N1Mx; initial prostate specific antigen (PSA) was 1.2 ng/mL; ⁶⁸68Ga-prostate specific membrane antigen PET/CT (⁶⁸Ga-PSMA PET/CT) suggested abnormal uptake of nuclear lesions in the prostate (SUV4.2-5.3); biopsy results indicated invasive mucinous adenocarcinoma.After prostate and pelvic field radiotherapy + androgen deprivation therapy (ADT) + antihypertensive treatment, lesions were significantly reduced, and hematuria symptoms were relieved.In case 2, the clinical manifestation was dysuria; initial PSA was 91.78 ng/mL; mpMRI suggested invasion of prostate mass into the bladder and clinical stage of T4N1M1b; ⁶⁸Ga-PSMA PET/CT indicated prostate and pelvic lymph nodes, and multiple bone lesions showed increased nuclide uptake; biopsy results indicated prostate adenocarcinoma with mucinous adenocarcinoma.Initial endocrine treatment was performed.After 3 months, PSA was reduced to 0.083 ng/mL, and imaging showed the tumor was significantly reduced.Robotic-assisted laparoscopic tumor prostatectomy with extended pelvic lymph node dissection was performed, and endocrine adjuvant therapy was continued after surgery. 【Conclusion】 Prostate mucosa adenocarcinoma has different clinicopathological characteristics and prognosis from conventional acinar adenocarcinoma, and the whole-process management under MDT mode is of great value in the diagnosis and treatment of this disease.

Stress urinary incontinence (SUI) and underactive bladder (UAB) are common types of lower urinary tract dysfunction in women.As the treatment mechanisms of the two conditions are contradictory, the treatment of SUI patients complicated with UAB remains a difficult clinical problem.In order to improve the treatment rate of such patients and promote research, this paper reviews the latest domestic and overseas diagnostic criteria of UAB, summarizes the treatment experience of conventional midurethral sling (tension-free vaginal tape or outside-in transobturator tape) and adjustable sling procedures (transobturator adjustable tape or Remeex system) combined with medication or intermittent catheterization, and the application prospects of cutting-edge technologies such as stem cell injection, cytokine therapy and gene therapy, so as to provide reference for clinicians and researchers.

Objective:To correlate serum Nesfatin-1, N-terminal pro-brain natriuretic peptide (NT-proBNP), and cystatin C (CysC) levels with myocardial enzymes and cardiac function in patients with acute ST-elevation myocardial infarction (STEMI).Methods:This is a case-control study. A total of 100 patients with acute STEMI who received treatment at Lishui People's Hospital from January 2020 to December 2022 were included in the STEMI group. An additional 80 healthy controls who concurrently received physical examinations in the same hospital were included in the control group. Serum levels of Nesfatin-1, NT-proBNP, CysC, creatine kinase-MB (CK-MB), and cardiac troponin I (cTnI) levels were determined in each group. Left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVDD), and left ventricular end-systolic diameter (LVDS) were measured using color Doppler ultrasound. Correlation analysis was performed.Results:Serum Nesfatin-1 level in the STEMI group was (89.96 ± 15.25) ng/L, which was significantly lower than (226.36 ± 37.47) ng/L in the control group ( t = 33.15, P < 0.05). Serum levels of NT-proBNP and CysC in the STEMI group were (1 325.12 ± 378.48) ng/L and (1.37 ± 0.24) mg/L, which were significantly higher than (78.95 ± 13.42) ng/L and (0.79 ± 0.16) mg/L in the control group ( t = -29.42, -18.56, both P < 0.05). Serum CK-MB and cTnI levels in the STEMI group were (46.51 ± 12.14) U/L and (1.13 ± 0.25) U/L, respectively, which were significantly higher than (12.23 ± 4.01) U/L and (0.09 ± 0.02) U/L in the control group ( t = -24.06, -37.09, both P < 0.05). The LVEF in the STEMI group was (37.84 ± 5.45)%, which was significantly lower than (72.41 ± 4.26)% in the control group ( t = 46.49, P < 0.05). The LVDD and LVDS in the STEMI group were (40.92 ± 5.25) mm and (58.98 ± 6.25) mm, which were significantly higher than (19.86 ± 3.36) mm and (34.21 ± 4.38) mm in the control group ( t = -31.13, -30.03, both P < 0.05). Serum Nesfatin-1 level was positively correlated with LVEF ( r = 0.572), but it was negatively correlated with serum CK-MB and cTnI levels, LVDD, and LVDS ( r = -0.498, -0.617, -0.506, -0.534, all P < 0.05). Serum NT-proBNP and CysC levels were negatively correlated with LVEF ( r = -0.653, -0.607), but they were positively correlated with serum CK-MB and cTnI levels, LVDD, and LVDS ( r = 0.582, 0.526, 0.712, 0.565, 0.631, 0.578, 0.659, 0.635, all P < 0.05). Conclusion:Serum Nesfatin-1 levels decrease, while serum NT-proBNP and CysC levels increase in patients with acute STEMI. Serum Nesfatin-1, NT-proBNP, and CysC levels are closely related to myocardial enzymes and cardiac function.

Objective:To design and evaluate the application value of intracavitary-interstitial brachytherapy (IC-ISBT) applicator template for locally advanced cervical cancer.Methods:MRI data of 100 patients with ⅡB-ⅣA stage cervical cancer (International Federation of Gynecology and Obstetrics 2018 staging system) before and after external beam radiation therapy (EBRT) admitted to Sun Yat-sen University Cancer Center from March 2019 to September 2020 were collected. The range of primary cervical lesions was retrospectively analyzed and compared. Based on the residual mass of patients, the corresponding high-risk clinical target volume (HR-CTV) was delineated, and the IC-ISBT applicator template was designed and initially applied to cervical cancer patients. Dosimetry analysis and efficacy evaluation were compared between the applicator template-guided ( n=37) and free-hand implantation groups ( n=63). Chi-square test or Fisher exact test was performed for categorical variables, and t-test or U-test for continuous variables. Results:The median distance between the residual tumor margin (clockwise 3, 6, 9, 12 o'clock) and the center of 100 patients with ⅡB-ⅣA stage cervical cancer after EBRT was 16.5, 14.0, 17.0 and 13.0 mm, respectively. The corresponding HR-CTV was superimposed to reconstruct the three-dimensional diagram, and the cylindrical IC-ISBT applicator template with mushroom-like head was designed and manufactured: the longest and shortest diameter of the head was 35 and 20 mm, respectively; the central channel was adapted to the uterine tube, the C1-C12 channels was arranged in inner circle, and the peripheral B1-B5 and A1-A4 pin channels were expanded bilaterally. In terms of dose coverage, there was no significant difference between the HR-CTV D 90% [(635.12±22.65) vs. (635.80±25.84) cGy], bladder D 2 cm3 [(473.79±44.78) vs. (463.55±66.43) cGy)], rectum D 2 cm3 [(396.99±73.54) vs. (408.00±73.94) cGy] and sigmoid colon D 2 cm3 [(293.07±152.72) vs. (311.31±135.77) cGy] between the template-guided and free-hand implantation groups (all P>0.05), but the HR-CTV D 98% was significantly higher [(544.78±32.07) vs. (536.78±32.04) cGy, P=0.007] and the rectum D 1 cm3 and D 0.1 cm3 were significantly lower [(438.62±69.65) vs. (453.97±67.89) cGy, P=0.016; (519.46±70.67) vs. (543.82±81.24) cGy, P=0.001] in the template-guided implantation group. In addition, there was no significant difference in the complete response rate between two groups (86% vs. 83%, P>0.05). Conclusions:This IC-ISBT applicator template is reasonably designed, and the therapeutic efficacy of the template-guided implantation is equivalent to that of free-hand implantation. The dose coverage of the target area meets the clinical demand with a better protection of the organs at risk. The applicator template has the potential to be widely used as a conventional template in clinical practice as the applicator-guided implantation is convenient to operate and repeat.

Objective·To investigate the pathological and physiological changes underlying noise-induced cochlear nucleus damage and the regulating function of astrocytes on the damage,using a combination of morphological analysis,and molecular biology techniques.Methods·Forty-eight male C57BL/6J mice were randomly divided into two groups and exposed to 110 dB SPL(sound pressure level)broadband noise for 2 hours.Auditory brainstem response(ABR)tests were performed on the mice on days 1,7,14,30,and 90 after the noise exposure.Immunofluorescence staining of cochlear nuclear tissue was conducted to observe cochlear nuclear neurons and auditory synapses,as well as astrocyte activation levels.In addition,the damage to the cochlear nuclear neurons and synapses caused by noise was verified through Western blotting.Results·A significant decrease in cochlear nuclear Bushy cells after noise exposure was observed.The Western blotting results showed that there was severe loss of nerve fibers in cochlear nuclear neurons,indicating that noise caused significant damage to cochlear nucleus neurons.Moreover,a significant loss of auditory synapses labeled with vesicular glutamate transporter 1(Vglutl)was observed,which was the severest on day 14 after noise exposure and slowly recovered on day 90.Interestingly,astrocytes in the cochlear nucleus displayed obvious clustering and activation after noise exposure.By staining with glial fibrillary acidic protein(GFAP),most astrocytes were distributed around the cochlear nucleus,granule cell area,and auditory nerve root before noise exposure,and they had a small size.However,on day 14 after noise exposure,a large number of activated astrocytes aggregated in the ventral cochlear nucleus,and they all showed a pattern of growth around the synapses.Conclusion·Noise exposure leads to significant damage in the cochlear nucleus,and it is possible that astrocytes are involved in its damage and repair processes.These findings will provide a crucial foundation for further understanding the mechanisms of sound signal analysis,integration,and neural plasticity in the cochlear nucleus.

Objective:To summarize the genotype and clinical characteristics of chylomicron retention disease (CMRD) caused by secretion associated Ras related GTPase 1B (SAR1B) gene variations.Methods:Clinical data and genetic testing results of 2 children with CMRD treated at Children′s Hospital of Fudan University and Jiangxi Provincial Children′s Hospital from May 2022 to July 2023 were summarized. To provide an overview of the clinical and genetic characteristics of CMRD caused by SAR1B gene variations, all of the literature was searched and reviewed from China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, China VIP database, China Biology Medicine disc and PubMed database (up to January 2024) with "chylomicron retention disease" "Anderson disease" or "Anderson syndrome" as the search terms. All relevant literatures were reviewed to summarize the clinical and genetic features of CMRD caused by SAR1B gene variations.Results:One 11-year-old boy and one 4-month-old girl with CMRD. Both patients had lipid malabsorption, failure to thrive, decreased cholesterol, elevated transaminase and creatine kinase, and Vitamin E deficiency, with homozygous variations (c.224A>G) and compound heterozygous variations (c.224A>G and c.554G>T) in SAR1B gene, respectively. Case 1 was followed up for over a month, and he still occasionally experienced lower limb muscle pain. Case 2 was followed up for more than a year, and her had caught up to normal levels. Both patients had no other significant discomfort. Literature search retrieved 0 Chinese literature and 22 English literatures. In addition to the 2 cases reported in this study, a total of 51 patients were identified as CMRD caused by SAR1B gene variations. Twenty-one types of SAR1B variants 10 missense, 4 nonsense, 3 frameshift, 1 in-frame deletion, 1 splice, 1 gross deletion, and 1 gross insertion-deletion were found among the 51 CMRD cases. Among all the patients, 49 cases had lipid malabsorption (43 cases had diarrhea or fatty diarrhea, 17 cases had vomiting, and 12 cases had abdominal distension), 45 cases had lipid soluble Vitamin deficiency (43 cases had Vitamin E deficiency, 10 cases had Vitamin A deficiency, 9 case had Vitamin D deficiency, and 5 cases had Vitamin K deficiency), 35 cases had failure to thrive, 32 cases had liver involvement (32 cases had elevated transaminases, 5 cases had fatty liver, and 3 cases had hepatomegaly), 29 cases had white small intestinal mucosa under endoscopy, and 17 cases had elevated creatine kinase, 14 cases had neuropathy, 5 cases had ocular lesions, 2 cases had acanthocytosis, 1 case had decreased cardiac ejection fraction, and 1 case was symptom-free.Conclusions:Early infancy failure to thrive and lipid malabsorption are common issues for CMRD patients. The laboratory tests are characterized by hypocholesterolemia with or without fat-soluble Vitamin deficiency, elevated liver enzymes and (or) creatine kinase. Currently, missense variations are frequent among the primarily homozygous SAR1B genotypes that have been described.

Objective To investigate the related factor underlying the differential vulnerability of inner hair cell(IHC)ribbon synapses to noise exposure.Methods Twenty-eight C57BL/6J mice were randomly divided into the noise exposure group(NED1)and the control group(CTR)with 14 mice in each group.The noise exposure group was exposed to bandpass noise of 2～20 kHz at 103 dB SPL for two hours while the control group was bred in a quiet environment.Before and after noise exposure,auditory brainstem response was conducted to detect the audi-tory function,whole-mount immunofluorescence staining was used to observe the number of inner hair cell ribbon synapses in different turns.The calcium influx of inner hair cells in the apical and middle turn using whole-cell patch clamp recording was analyzed.Furthermore,the immunofluorescence intensity of calpain in inner hair cells from dif-ferent mouse cochlear turns using whole-mount immunofluorescence staining was compared.Western blotting was used to verify that CtBP2 was degraded by calpain.Results After noise exposure,the ABR threshold of 11.3,16.0,22.6,32.0 kHz increased significantly and the number of ribbon synapses of inner hair cells at the middle turn and basal turn of the cochlea decreased significantly.However,whole-cell patch clamp recordings showed that calcium ion channels were fewer but single-channel current was higher at the apical turn of the cochlea.The open probability of calcium ion channels in IHCs showed no significant difference between the apical turn and the middle turn of the cochlea.But the expression level of calpain of the inner hair cells at the middle and basal turn of the basi-lar membrane was significantly higher than that at the apical turn after noise exposure.The western blotting results also showed that CtBP2 was cleaved in a Ca2+-dependent manner by calpain.Conclusion Calpain may be the main related factor that accounts for the vulnerability of ribbon synapses in inner hair cells in the high frequency region of basal membrane.

African swine fever virus(ASFV)I177L gene deletion vaccine is one of the key directions of African swine fever(ASF)live attenuated vaccine research and development.In order to effec-tively distinguish between the wild-type ASFV strain and the I177L gene-deleted strain,specific primers and probes were designed based on ASFV B646L and I177L genes,respectively.After screening and optimization,a duplex real-time PCR method was developed that can simultaneously detect these two genes.The results showed that ASFV B646L and I177L genes were detected spe-cifically and simultaneously by the method developed without cross-reactions with porcine circovir-us type 2,Seneca virus A,classical swine fever virus,foot-and-mouth disease virus,porcine respira-tory and reproductive syndrome virus.The detection limits of the duplex real-time PCR for recom-binant plasmids pUC57-B646L and pUC57-I177L were 1×103 copies/mL.The intra-and inter-as-say coefficients of variation were less than 4％,respectively.Detection of 122 pork and pork prod-ucts using the duplex real-time PCR developed and the real-time PCR recommended by WOAH showed that the coincidence rates of the two methods for B646L gene detection was 100％with two amplification curves appeared in the positive results of the established methods.The method established in this study can be used for the detection of ASFV I177L gene deletion strains,which provides technical support for ASF surveillance and epidemiological investigation.
