Objective:To retrospectively analyze the efficacy and feasibility of surgical management in patients with cervical dysphagia secondary to Diffuse idiopathic skeletal hyperostosis(DISH)of the cervical spine.Methods:A retrospective analysis was conducted on 6 patients who presented with dysphagia as the primary symptom, were diagnosed with cervical DISH, and underwent surgical treatment in the Department of Otorhinolaryngology Head and Neck Surgery of The Second Xiangya Hospital of Central South University from January 2018 to February 2024. There were 5 males and 1 female, aged from 65 to 78 years (70.2±4.7 years). The duration of dysphagia prior to admission was 13 to 18 months (14.7±2.2 months). All patients had the symptom of dysphagia, and at least one other clinical manifestation of cervical DISH (dyspnea, restricted neck mobility, sleep apnea, odynophagia). One patient had undergone tracheotomy due to laryngeal obstruction before surgery. Surgical intervention was performed after failure of conservative management in all patients. All patients underwent anterior cervical osteophyte resection via the Smith-Robinson approach without concomitant spinal fusion. In the patient with prior tracheotomy for airway obstruction, epiglottoplasty and right arytenoidectomy were performed simultaneously. The swallowing function was evaluated by water swallow test, FEES, M. D. Anderson Dysphagia Inventory. Clinical and imaging evaluations were conducted for follow-uppostoperatively. Preoperative and 30-day post operative data were statistically analyzed using paired samples t-test.Results:Cervical computed tomography revealed osteophyte involvement from C2 to T1 with a median of 4 vertebral segments affected. The most frequently involved vertebral segments were C4-C6 (all 6 patients were involved). The anteroposterior diameter of the most prominent osteophyte was 12.0 to 20.0 mm (16±3.1 mm). The time to resumption of a regular diet was 6 to 20 days(12.7±5.3 days), and the time to remove the nasogastric tube was 8 to 25 days(15.2±6.2 days). In the patient with prior tracheotomy, the tracheostomy tube was successfully decannulated 30 days after initial tube capping following conversion to a metal tube. All cervical DISH-related symptoms except for limited neck mobility improved postoperatively. Both water swallow test and the Rosenbek Penetration-Aspiration Scale showed significant improvement postoperatively. At 30 days postoperatively, MDADI scores significantly improved in all domains: l global (73.33±10.33), emotional (85.56±8.35), functional (83.33±5.89), and physical (82.08±6.60). No major perioperative complications occurred. and the length of hospital stay was 7 to 10 days (7.8±1.2 days). The follow-up time was 12 to 84 months (43.7±27.2 months). All patients maintained sustained symptom relief, with no evidence of osteophyte recurrence during follow-up.Conclusion:Cervical DISH is an under-recognized causes of dysphagia in elderly patients and warrants attention from otolaryngologists. For patients erefractory to conservative treatment, anterior resection of cervical osteophytes via the Smith-Robinson approach is a safe, minimally invasive procedure with favorable short-and long-term outcomes in improving swallowing function.

ObjectiveTo investigate the molecular mechanisms of Mahuang Fuzi Gancao Tang and its pungent single herbs， Ephedrae Herba and Aconiti Lateralis Radix Praeparaia， in repairing podocyte injury based on the sweat pore theory， with a focus on the podocyte cytoskeletal transient receptor potential canonical 5 （TRPC5）-Ras-related C3 botulinum toxin substrate 1 （RAC1） feedforward loop. MethodsAn animal model with puromycin aminonucleoside （PAN）-induced overexpression of TRPC5 was established. Interventions included Mahuang Fuzi Gancao Tang， Ephedrae Herba alone， and Aconiti Lateralis Radix Praeparaia alone. Biochemical parameters ， histopathological changes， and podocyte ultrastructure were analyzed. Western blotting was performed to determine the expression of cytoskeletal protein synaptopodin and mechanism-related proteins TRPC5， RAC1-GTP， and RAC1 in the kidney. Primary podocytes were isolated and cultured for three-dimensional imaging of foot processes， cytoskeletal fluorescence analysis， and TRPC5-RAC1 co-staining via immunofluorescence. ResultsCompared with the model group， Mahuang Fuzi Gancao Tang， Ephedrae Herba alone， and Aconiti Lateralis Radix Praeparaia alone increased serum albumin （ALB）， decreased UPCR， reduced podocyte foot process fusion rate， upregulated synaptopodin expression， and downregulated TRPC5， RAC1-GTP， and RAC1 expression （P<0.05）. Moreover， the interventions increased the phalloidin fluorescence area/field area ratio （P<0.01） and mean fluorescence intensity （P<0.05）， while decreasing the proportion of TRPC5-RAC1 co-stained double-positive cells/total cells per field （P<0.01） in primary podocytes. ConclusionMahuang Fuzi Gancao Tang and its pungent single herbs， Ephedrae Herba and Aconiti Lateralis Radix Praeparaia， ameliorated podocyte injury in the model with PAN-induced TRPC5 overexpression by reducing proteinuria and suppressing the TRPC5-RAC1 feedforward loop-mediated podocyte cytoskeletal damage.

The Xuanfu theory of Qi and liquid is an important theory guiding clinical practice of traditional Chinese medicine(TCM).Xuanfu and glomerular podocytes are highly consistent in terms of physiological structure,pathological phenotype,clinical characteristics,and therapeutic principles.Clinical applications of Xuanfu-opening therapy were observed to effectively mitigate podocyte injury and alleviate nephrotic syndrome due to podocytopathies.This article,based on clinical implementations of Xuanfu-opening therapy for podocytopathy,integrated evidence from Chinese and Western medical evidence to systematically establish the correlations between renal Xuanfu mechanisms and podocyte pathophysiology.Through rigorous comparative analysis,we elucidated the dynamic pathological progression spanning Xuanfu phases,including opening,constriction,obstruction,and atrophy and delineated its mechanistic association with podocyte injury cascades involving foot process effacement and apoptotic pathways.Furthermore,we proposed a therapeutic framework utilizing pungent-flavored phytochemicals as the core intervention for Xuanfu-opening therapy in podocytopathies,while constructing a preliminary theoretical model for Xuanfu-podocyte interactions.These findings provided references for TCM-based management for glomerular podocyte disorders and significantly enriched the medical connotation of the Xuanfu theory.

The"lipid nephrotoxicity"hypothesis introduces the lipid metabolism disorders into the field of kidney disease research.Fatty acids as important components of lipids can be ectopic deposition in various cells of the kidney in pathological status,and are involved in the occurrence and progression of acute kidney in-jury(AKI)and chronic kidney disease(CKD).The mechanism of abnormal fatty acid metabolism in tubular epithelial cells(TEC)and its function change are closely associated with kidney injury.This article summa-rized the relationship between fatty acid metabolism in TEC with AKI and CKD,elaborated the specific mech-anism of fatty acid metabolism disorders leading to TEC injury,and discussed the treatment strategies based on regulating fatty acid metabolism disorders to improve kidney injury.

[Objective]To discuss the pathogenesis,hierarchy,treatment and medication rules of deficiency of Yang with hyperactivity of Yin syndrome in Treatise on Febrile Diseases.[Methods]Combining with the medical theory of later physicians,this paper clarifies the pathogenesis and syndrome of deficiency of Yang with hyperactivity of Yin syndrome,explains the mechanism of Yang deficiency and Yin excess syndrome from the perspective of pathophysiology.This paper also analyzes the differences among the various versions of the text of the Shaoyin Chapter including the variations in disease location,the pathogen nature,stomach Qi and body fluid,and inducts the implicit therapeutic principles in the Shaoyin Chapter.[Results]The principle of differentiation and treatment for deficiency of Yang with hyperactivity of Yin syndrome is"protecting stomach Qi and preserving body fluids",which can be subdivided into Taiyin damp earth disease,Shaoyin monarch fire disease,and Jueyin wind wood disease.Through careful observation,questioning,smelling and palpation,combined with the pathological and physiological basis of modern medicine,it can accurately diagnose deficiency of Yang with hyperactivity of Yin syndrome.Shaoyin plays a crucial role in Treatise on Febrile Diseases.The structure of the Shaoyin Chapter is well-organized and can dynamically reflect the changes in the pathogenesis of Shaoyin syndrome,the combination of Shaoyin and Taiyin or Jueyin,or the tri-coordination syndrome of these location.From the text,it can be inferred that the location of the disease begins on the surface and gradually extends to the interior.The treatment methods will include moxibustion,warming the meridians,warming Yang and dredging Yang.The severity of the illness and the presence of phlegm-fluid determine the treatment,which may involve dispersing cold,dispersing fluids,and promoting urination.The degree of exhaustion of bodily fluids may require either reviving Yang for resuscitation or nourishing Yin.[Conclusion]From a pathological and physiological perspective,the mechanisms behind the changes in the primary symptoms of traditional Chinese medicine can be explained.When treating deficiency of Yang with hyperactivity of Yin syndrome,the selection of herbal prescriptions should be based on factors such as the disease location,the pathogen nature,stomach Qi and body fluids.The treatment principles for deficiency of Yang with hyperactivity of Yin syndrome have instructive significance for the treatment of other syndromes as well.
