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 investigate the therapeutic effect and mechanisms of live combined bifidobacterium and lactobacillus tablets on slow transit constipation(STC)rats.Methods A total of 30 SPF grade Wistar adult female rats were blinded and divided into control group,model group,live combined bifidobacterium and lactobacillus tablets low-dose(0.270g/kg),live combined bifidobacterium and lactobacillus tablets medium dose group(0.540g/kg),live combined bifidobacterium and lactobacillus tablets high-dose group(1.080g/kg),and positive drug group(prucalopride succinate tablet)(0.180mg/kg),with 5 rats in each group.A rat model of STC was established by gavage of loperamide hydrochloride.After successful modeling,medication was administered by gavage for 14 consecutive days on the basis of continued modeling.Observe the changes in general physical signs,fecal water content,and calculate intestinal motility in each group of rats.Using HE staining to observe pathological changes in colon tissue,immunohistochemical methods were used to detect the protein expression of receptor tyrosine kinase(c-Kit),5-hydroxytryptamine(5-HT),5-hydroxytryptamine 3 receptor(5-HT3R),and 5-hydroxytryptamine 4 receptor(5-HT4R)in rat colon tissue.Results Compared with control group,frequency of defecation,fecal water content and intestinal propulsion speed of STC model rats were significantly decreased.The expression levels of proteins such as c-Kit,5-HT,5-HT3R,and 5-HT4R in intestinal tissues were significantly reduced in STC model rats.Compared with STC model group,rats treated with low,medium and high doses of live combined bifidobacterium and lactobacillus tablets and positive drug groups showed a significant increase in bowel frequency,fecal water content,and intestinal motility after intervention.Compared with STC model group,frequency of defecation,fecal water content,intestinal propulsion rate and protein expression of c-Kit,5-HT,5-HT3R and 5-HT4R in rat intestinal tissues were significantly increased after intervention of live combined bifidobacterium and lactobacillus tablets low,medium and high dose groups.Conclusion This study confirms that probiotic preparation live combined bifidobacterium and lactobacillus tablets effectively improves slow transit constipation by promoting the proliferation of Cajal interstitial cells in the colon,increasing the expression of 5-HT,5-HT3R,and 5-HT4R,enhancing intestinal peristalsis,and achieving the therapeutic effect on STC rats.

OBJECTIVE: To analyze the role and significance of pepsin and pepsinogen in the pathogenesis of OME in children. METHOD: Pediatric patients with otitis media aged 2-8 years who enrolled in our department of the hospital from May of 2012 to December of 2012 were set as experimental group (38 cases, 48 ears) which should be underwent tympanic membrane puncture/tube insertion. Meanwhile, pediatric patients waiting for cochlear implant without otitis media (10 ears), were set as control group. Middle ear lavage fluid and plasma samples from the two groups were collected and detected using enzyme-linked immune method for pepsin and pepsinogen. RESULT: The concentrations of pepsin and pepsinogen in the middle ear lavage fluid of OME group [(48.8 ± 415.99) ng/ml and 676.32 ± 336.71)ng/ml] were significantly higher than those in the control group [(8.20 ± 4.59)ng/ml and (77.27 ± 50.33) ng/ml] (P < 0.01). Meanwhile, the concentration of pepsinogen in the middle ear lavage of OME patients was significantly higher than that of plasma (P < 0.01). The concentration of pepsin in the middle ear lavage fluid from the dry ear subgroup was lower than those in the serum ear and mucous ear subgroups (P < 0.01), but there was no significant difference about concentrations of pepsinogen among the dry ear, serum ear and mucous ear subgroups (P > 0.05). CONCLUSION Pepsin and pepsinogen in the middle ear cavity of OME patients maybe originated from laryngopharyngeal reflux (LPR), indicating that LPR is associated with the pathogenesis of OME in children.
