Abstract
BACKGROUND Episodic memory loss is a prominent clinical manifestation of Alzheimer's disease (AD), which is closely related to tau pathology and hippocampal impairment. Due to the heterogeneity of brain neurons, the specific roles of different brain neurons in terms of their sensitivity to tau accumulation and their contribution to AD-like social memory loss remain unclear. Therefore, further investigation is necessary. METHODS We investigated the effects of AD-like tau pathology by Tandem mass tag proteomic and phosphoproteomic analysis, social behavioural tests, hippocampal electrophysiology, immunofluorescence staining and in vivo optical fibre recording of GCaMP6f and iGABASnFR. Additionally, we utilized optogenetics and administered ursolic acid (UA) via oral gavage to examine the effects of these agents on social memory in mice. RESULTS The results of proteomic and phosphoproteomic analyses revealed the characteristics of ventral hippocampal CA1 (vCA1) under both physiological conditions and AD-like tau pathology. As tau progressively accumulated, vCA1, especially its excitatory and parvalbumin (PV) neurons, were fully filled with mislocated and phosphorylated tau (p-Tau). This finding was not observed for dorsal hippocampal CA1 (dCA1). The overexpression of human tau (hTau) in excitatory and PV neurons mimicked AD-like tau accumulation, significantly inhibited neuronal excitability and suppressed distinct discrimination-associated firings of these neurons within vCA1. Photoactivating excitatory and PV neurons in vCA1 at specific rhythms and time windows efficiently ameliorated tau-impaired social memory. Notably, 1 month of UA administration efficiently decreased tau accumulation via autophagy in a transcription factor EB (TFEB)-dependent manner and restored the vCA1 microcircuit to ameliorate tau-impaired social memory. CONCLUSION This study elucidated distinct protein and phosphoprotein networks between dCA1 and vCA1 and highlighted the susceptibility of the vCA1 microcircuit to AD-like tau accumulation. Notably, our novel findings regarding the efficacy of UA in reducing tau load and targeting the vCA1 microcircuit may provide a promising strategy for treating AD in the future.

Abstract
Objective:To assess the efficiency and safety of balloon dilation tracheoplasty technique in the management of acquired subglottic stenosis in children. Method:Twenty-three cases were diagnosed as acquired subglottic stenosis by chest CT scan and bronchoscpy,and received the treatment of the balloon dilatation tracheoplasty.The data about the efficiency,complication and prognosis of the treatment were collected. Result:In the 23 cases,6 of All 11 patients with tracheotomy were decannulated,11 patients were successfully managed without tracheotomy,1 patients received laryngotracheal reconstruction(LTR) surgery, 5 cases were still under observation. The overall response rate was 73.91%.All cases were divided into three stages according to Cotton stage system:1 cases were stage Ⅰ stenosis,6 cases were stage Ⅱ and 16 cases were stage Ⅲ. The response rate was 100.00%,83.33%,and 68.75% respectively. The most common complication in the balloon dilatation tracheoplasty was restenosis. Restenosis occurs in 12(52.17%) cases who received more than 1 dilation procedures in this study. Over all average dilation times is 1.87. Eight cases(88.9%) of 9 in fresh leision group were recoverd, the average dilation time is 1.22; 8 cases (57.14%) of 14 in old leision group were recoverd, the average dilation time is 2.23. The average dilation time between two group is significant(P<0.05). Conclusion:Subglottic stenosis in pediatric patients can be successfully managed with balloon dilation tracheoplasty. In patients without prior tracheotomy, tracheotomy can often be safely avoided with appropriate postoperative management.
