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 develop a health behavior guidance program for stroke rehabilitation patients based on the adaptive leadership framework (ALF) .Methods:Relevant stroke health behavior guidelines were systematically retrieved, screened, included, and recommendations extracted from domestic and international websites. The initial draft of the health behavior guidance program for stroke rehabilitation patients was developed in light of the ALF. From January to March 2022, the draft was refined through two rounds of Delphi expert consultation, resulting in the finalized health behavior guidance program.Results:A total of 10 guidelines were included, and 73 guideline recommendations were extracted. These recommendations were categorized into six dimensions and 25 specific items. In both rounds of expert consultation, 15 questionnaires were distributed and all were returned, yielding an effective recovery rate of 100.00%, with an expert authority coefficient greater than 0.8. Based on expert feedback and group discussions, the final program included eight dimensions and 31 items, adding sleep management and regular health consultations to the original six dimensions.Conclusions:The health behavior guidance program for stroke rehabilitation patients, based on the ALF, introduces a new perspective on nursing by reasonably dividing adaptive and technical problems. This approach aligns with clinical practice in China, providing scientific and practical value for promoting health behaviors and offering a new perspective for health education in stroke patients.

Objective:To explore the correlation between fasting plasma glucose (FPG) trajectory and new-onset chronic kidney disease (CKD) in elderly population (≥65 years old) in Nanjing.Methods:The study cohort was composed of 14 763 subjects who met the inclusion criteria in the population in elderly health examination in Nanjing. Based on the FPG levels detected in health examination from 2018 to 2021 (logarithm was used for normal distribution), three different FPG trajectory groups were determined using the SAS Proc Traj program, i.e. low-stable group, medium-stable group, and high-stable group. The incidence of CKD in 2022 was analyzed, and log-rank test was performed to compare the differences of cumulative incidence of new-onset CKD among different trajectory groups. Cox proportional hazards regression model was used to analyze the correlation between different FPG trajectories and new-onset CKD.Results:The mean follow-up time was (416.09±81.96) days. The follow-up time of the 500 th day was selected to analyze the cumulative incidence rate of CKD in different FPG trajectory groups, and the cumulative incidence rate of CKD in the low-stable group, the medium-stable group, and the high-stable group of FPG increased with elevated trajectory, which was 15.3%, 21.8%, and 29.3%, respectively (log-rank test χ2=151.16, P<0.001). Cox proportional hazards regression model analysis showed that compared with the low-stable group, the medium-stable group and the high-stable group were all at risk for new-onset CKD. After adjusting for multiple confounding factors, the analysis by Cox proportional hazards regression model 4 indicated that the risk for CKD in medium-stable and high-stable groups were still 1.676 (95% CI: 1.462-1.921) times and 2.007 (95% CI: 1.562-2.579) times higher than that in low-stable group. Conclusions:Elevated FPG change trajectory level is a risk factor for new-onset CKD, and persistently high level of FPG increase the risk for CKD. FPG should be monitored in elderly population by follow up, and individualized prevention and control measures for CKD should be developed for different trajectory groups.

Objective To study the tumor targeting ability and application of farnesylthiosalicylic Acid (FTS) and heptamethine carbocyanine fluorescent dye-mediated near-infrared imagine in living animals, and confirm the inhibitory effect of this compound on growth of tumor cells.Methods Human breast cancer cell line MCF-7, glioma cell line U251 and prostate cancer cell line PC3 were cultured to logarithmic growth phase, and different concentrations of FTS and FTS-IR783 were added, respectively.We observed the inhibitory effect of those two compounds on the growth of tumor cells.Under fluorescence microscopy, specific accumulation of FTS-IR783 in these tumor cells was observed.The tumor cells (1×106) were transplanted subcutaneously into nude mice.These mice were subjected to intraperitoneal injection of FTS-IR783 (10 nmol/mouse) two weeks later.In the in vivo imaging, near infrared fluorescence signal and tumor volume were measured and their correlation was analyzed.Results Compared with FTS, FTS-IR783 significantly inhibited the growth of MCF-7, U251 and PC3 cells in vitro.FTS-IR783 was specifically uptaken by these three kinds of tumor cells, showing strong near infrared fluorescence in cell agglomerates.After subcutaneous injection of FTS-IR783, the correlation between fluorescence intensity and tumor volume was 0.987, 0.998 and 0.971, respectively.Conclusions The compound of FTS conjugated with near infrared fluorescent dye IR-783 can specifically recognize tumor cells, in both in vitro and in vivo imaging.At the same time, the compound can significantly inhibit the growth of tumor cells, and may be expected to become a new potential targeted drug.

BACKGROUND:Tumor stem cels are the root of cancer recurrence and metastasis, so clinical researches should focus on the effects of different treatments on tumor stem cels.
OBJECTIVE:To explore the effects of endocrine therapy and chemotherapy on stem cels in patients with breast cancer.
METHODS:After recovery and cultivation of estrogen receptor-positive human breast cancer cel lines MCF-7, passage 3 cels in logarithmic phase were selected and divided into three groups containing control, estradiol and estradiol with tamoxifen groups. The estradiol group was divided into three subgroups: 10-7, 10-8 and 10-9 mol/L estradiol was added into the medium, respectively; the estradiol with tamoxifen group was divided into three subgroups: 10-7, 10-8 and 10-9 mol/L estradiol with 10-6 mol/L tamoxifen were added into the medium, respectively. The same amount of absolute ethyl ethanol was added into the medium of control group. Fifteen female patients with late recurrence and metastasis of breast cancer received chemotherapy as recurrence and metastasis group. Another 15 healthy volunteers were selected as healthy control group.
RESULTS AND CONCLUSION:The proportion of CD44+CD24-/lowcel subsets in the estradiol and estradiol with tamoxifen groups was significantly higher than that of the control group (P < 0.05), and the proportion of CD44+CD24-/low cel subsets in the estradiol group was significantly higher than that of the estradiol with tamoxifen group at the same concentration (P< 0.05). The proportion of CD44+CD24-/lowcel subsets had no significant differences among groups at 10 and 20 days of culture (P < 0.05). The proportion of CD44+CD24-/low cel subsets significantly increased in MCF-7 cels after 24-hour intervention with different chemotherapy drugs. But only the proportion of CD44+CD24-/low cel subsets in the paclitaxel and doxorubicin groups was significantly higher than that of the control group after 20-day intervention (P < 0.05). Besides, the proportion of CD44+CD24-/low cel subsets in the peripheral blood of healthy volunteers was significantly lower than that of the recurrence and metastasis group (P < 0.05). Among 15 patients with late recurrence and metastatic of breast cancer, 9 had stable disease, 5 had partial remission, 1 had failed chemotherapy and cancer progression. Moreover, the proportion of CD45-CD44+CD24-/low cel subsets in the peripheral blood of patients sensitive for chemotherapy was significantly lower than that before treatment (P < 0.05). In conclusion, both endocrine therapy and chemotherapy exert a certain effect on the CD44+CD24-/low cel subsets of breast cancer positive for estrogen receptor. Given that CD44+CD24-/low cel subsets in MCF-7 cels resist chemotherapy drugs, the proportion of CD45-CD44+CD24-/low cels in the peripheral blood of patients sensitive for chemotherapy is decreased.

Objective To investigate the therapeutic effect of early stage minimally invasive laparoscopic retroperitoneal approach of catheter drainage on early inflammatory response of severe acute pancreatitis ( SAP ) . Methods 37 SAP patients with peritoneal effusion were divided into the observation group (19 cases with early laparoscopic retroperitoneal approach of catheter drainage )and normal treatment group(18 cases with conventional drainage)using a random number table.All patients were given conventional therapy , such as fasting, gastroin-testinal decompression , anti-infection, fluid resuitation and using gastric acid and trypsin inhibitors .In addition to conventional therapy , the observation group received the early laparoscopic retroperitoneal approach of catheter drainage.The inflammatory indexes responding to acute inflammation such as TNF-α,IL-6,IL-8, IL-10 and C-re-active protein(CRP)were detected before and after treatment .Meanwhile, the date of resume diet, APACHEⅡscores and duration of systemic inflammatory response ( SIRS) , incidence of multiple organ dysfunction syndrome ( MODS) and the mortality were observed .Results The acute inflammatory response occurred in both groups . The plasma levels of TNF-a,IL-6,IL-8,IL-10 and CRP in the two groups decreased obviously after 3-day treat-ment.However, the plasma levels of inflammatory mediators in the normal treatment group increased while those early laparoscopic retroperitoneal approach of catheter drainage group kept decreasing after 7-day treatment .There was a significant difference between the two groups (P<0.01).Time for resuming to diets and duration of SIRS in the observation group were less than those in the normal treatment group ( P<0.01 ) , APACHEⅡscore were significantly less than those in normal treatment group also (P<0.01).The rates of MODS, overall postoperative complication rate and mortality were significantly lower in the observation group (P<0.05).Conclusions Early laparoscopic retroperitoneal approach of catheter drainage can effectively improve the prognosis in patients with SAP and decrease the production of inflammatory mediators .Early laparoscopic retroperitoneal approach of cathe-ter drainage is simple , feasible and micro-invasive with encouraging outcomes , therefore it is an effective and safe treatment option for patients with SAP .
