Neurological diseases have high morbidity and disability rates， posing a severe threat to human health. Cli nical manifestations include motor， sensory， cognitive and conscious disorders. Chaihu jia longgu muli decoction is derived from Treatise on Febrile Diseases ， with the effects of harmonizing Shaoyang， activating Yang and clearing heat， and tranquilizing the mind. This paper systematically reviews the research progress in clinical application and mechanism of Chaihu jia longgu muli decoction in the field of neurological diseases. It has been found that the decoction shows favorable efficacy in various neurological diseases such as insomnia， depression， epilepsy， vertigo， migraine and vascular dementia. The specific mechanisms are related to regulating neurotransmitter levels， repairing neuronal function， alleviating neuroinflammation， improving mitochondrial dysfunction and regulating intestinal flora. In the future， standardized prospective follow-up cohorts should be established， and core outcome indicators should be clearly defined to strengthen the evidence base. Furthermore， multidisciplinary research should be leveraged to expand the therapeutic value of Chaihu jia longgu muli decoction in the management of neurological diseases.

Objective To explore the roles of the mechanoreceptor Yes-associated protein 1(YAP1)and piezo type mechanosensitive ion channel component 2(PIEZO2)in mechanotransduction in mouse bladder urothelial cells.Methods Mouse bladder urothelial cells were subjected to mechanical stretching using the FX-6000T cell stretching system and treated with the YAP1-specific inhibitor verteporfin(VP).The expressions of PIEZO2,YAP1 and connective tissue growth factor(CTGF)at the mRNA and protein levels,as well as changes in cellular adenosine triphosphatase(ATP)concentration,were detected using reverse transcription quantitative PCR(RT-qPCR)and Western blotting(WB).Results After stretching stimulation,under the fluorescence microscope,it was observed that the diameter length of the stretched cells were longer than that before stretching,and the difference was statistically significant(P＜0.05).The expressions of YAP1,PIEZO2 and CTGF at the mRNA and protein levels were increased in the stretched group compared to those of the non-stretched group(P＜0.05).VP effectively reduced the expressions of YAP1,PIEZO2 and CTGF at the mRNA and protein levels after stretching stimulation(P＜0.05).Stretching stimulation significantly increased the intracellular ATP concentration,while VP was able to inhibit the increase in ATP concentration,with a statistically significant difference(P＜0.000 1).Conclusion Stretching stimulation increased the expressions of YAP1 and PIEZO2 in bladder urothelial cells and promoted the release of ATP;verteporfin inhibited the increase in YAP1 activity and the overexpression of PIEZO2 caused by stretching,thereby reducing the release of ATP.It is suggested that mouse bladder urothelial cells may primarily sense mechanical signals through the YAP1-PIEZO2-ATP pathway.

Objective To study the impact of tympanic membrane opening on respiratory-driven middle ear pressure in patients with patulous eustachian tube(PET),using a simplified in vitro model.Methods CT imaging data from a PET patient(with full-length eustachian tube opening observed during a Valsalva maneuver followed by breath-holding)were used to design a simplified eustachian tube model.Two simplified in vitro models of the eusta-chian tube were constructed using silicone-based 3D printing technology and connected to a pressure controller and pressure sensors.The pressure controller was activated to introduce negative-pressure airflow into the nasopharyn-geal model to simulate respiratory-induced middle ear pressure fluctuations.A hemostat was used to alternately open and close the external interface of the middle ear chamber,simulating conditions of an open and intact tympanic membrane,while middle ear pressure was continuously monitored using pressure sensors.Results In the first mod-el,with-800 mbar negative pressure applied at the nasopharynx,the middle ear pressure stabilized between-3.9 mbar and-4.3 mbar with tympanic membrane opening,and between-7.9 mbar and-8.2 mbar with intact tym-panic membrane.In the second model,under the same pressure setting,middle ear pressure stabilized between-2.7 mbar and-3.1 mbar with tympanic membrane opening,and between-5.0 mbar and-7.7 mbar with intact tympanic membrane.Conclusion This study,based on a simplified in vitro model,demonstrates that tympanic membrane opening can effectively reduce respiratory-driven pressure in the middle ear.This phenomenon may partly explain the clinical efficacy of tympanostomy tube insertion in certain PET patients.

Objective To observe the value of deep learning image reconstruction(DLIR)algorithm in brain CT perfusion(CTP)using a protocol of 70 kVp and 40 ml contrast agent dose.Methods Totally 105 patients with suspected acute ischemic stroke(AIS)were prospectively enrolled and randomly divided into 3 groups,who underwent standard dose CTP scanning with 80 kVp and 150 mA combined with reconstruction as adaptive statistic iterative reconstruction V(ASIR-V)at 50％level(CN group,n=35),low dose(LD)scanning with 70 kVp and 100 mA combined with DLIR reconstruction at the highest level(DLIR-H)(LD group,n=35),or ultra-low dose(ULD)scanning with 70 kVp and 70 mA combined with DLIR-H reconstruction(ULD group,n=35).Radiation doses were compared among 3 groups.CT values and standard deviations(SDCT)of ROI of gray matter and white matter in the frontal,parietal and temporal lobes were measured.Signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)between gray and white matter were calculated and compared among groups.Then pseudo-color images of cerebral blood volume(CBV),cerebral blood flow(CBF),mean transit time(MTT)and time to maximum of the tissue residual function(Tmax)were generated.The imaging quality of CTP pseudo-color images was evaluated,and the compatibility of the subjective scores within every kind of CTP pseudo-color images were assessed using Kappa test.Quantitative perfusion parameters were measured and compared among groups.Results Compared with CN group,both LD and ULD groups demonstrated significantly reduced volume CT dose index(CTDIvol),dose-length product(DLP)and effective dose(ED)(all adjusted P＜0.05).In ULD group,SDCT of white matter in frontal,parietal and temporal lobes were higher than those in CN group,and SDCT of white matter in parietal lobe was also higher than that in LD group(all adjusted P＜0.05).No significant difference of SDCT of gray matter was observed among groups(all P＞0.05).SNR of white matter in parietal and temporal lobes in both LD and ULD groups were lower than those in CN group(all P＜0.05),while no significant difference of SNR of white matter in frontal lobe,nor of gray matter in frontal,parietal and temporal lobes was found among groups(all P＞0.05).CNR of gray and white matter in the frontal,parietal and temporal lobes were not significantly different among groups(all P＞0.05).High consistency of inter-observer subjective scores of CBV maps,CBF maps and Tmax maps(Kappa of 0.623,0.644 and 0.638,respectively)were noticed,which of MTT maps had moderate consistency(Kappa=0.560).No significant difference of intra-obsever subjective scores of CTP pseudo-color images was found among groups(all P＞0.05).CBV,CBF,MTT and Tmax values of gray and white matter in frontal,parietal and temporal lobes were not significantly different among groups(all P＞0.05).Conclusion DLIR algorithm applicated in low radiation dose and reduced contrast agent dosage might ensure imaging quality.

Objective To investigate the correlation between hemoglobin A1c(HbA1c)levels and excessive daytime sleepiness(EDS)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 132 T2DM patients and 40 healthy people(NC group)who were treated in the outpatient department of Nanjing Meishan Hospital from December 2020 to December 2022 were selected.General clinical data of the subjects were collected,and their Epworth sleepiness scale(ESS)scores,Pittsburgh sleep quality index(PSQI),and apnea-hypopnea index(AHI)were measured.Based on ESS scores,T2DM patients were divided into simple T2DM group(ESS score<9,n=99)and EDS group(ESS score≥9,n=33)according to ESS score.The baseline data were compared for each group.Spearman correlation analysis and multivariate logistic regression model were used to evaluate the correlation between HbA1c levels and EDS.The receiver operating characteristic(ROC)curve was used to calculate the area under the curve(AUC)to evaluate the predictive value of HbA1c levels for EDS.Results HbA1c,fasting plasma glucose,AHI index and PSQI score in EDS group were higher than those in T2DM and NC group(P<0.05).Spearman correlation analysis showed that ESS score was positively correlated with HbA1c in T2DM patients(P<0.05).Multivariate logistic regression analysis revealed that elevated HbA1c levels emerged as a significant and independent risk factor for the onset of EDS.The ROC curve indicated that the AUC of HbA1c for predicting EDS was 0.736.Conclusions There is an independent positive correlation between HbA1c levels and EDS in T2DM patients,which provides clues for early identification and treatment of EDS in clinical practice.

Objective To analyze the respective abnormal brain regions and commonly altered brain regions of spontaneous brain ac-tivity in post-stroke aphasia(PSA)and post-stroke depression(PSD),and to explore the potential pathological mechanisms underlying single disease and comorbidity.Methods Literatures were retrieved from PubMed,Embase,Web of Science,Cochrane Library,CNKI,Wanfang data,VIP and SinoMed,from establishment to April 19th,2025.Resting-state functional magnetic resonance imaging(fMRI)studies were included if they focused on patients with PSA or PSD,with healthy controls(HC)serving as control group,and amplitude of low-frequency fluctuation(ALFF),fractional amplitude of low-frequency fluctu-ation(fALFF)and regional homogeneity(ReHo)were adopted as outcome indicator.Data regarding differential brain regions were extracted from the original studies,and a neuroimaging meta-analysis was conducted using SDM-PSI V6.23 beta.Results A total of 17 articles on PSA(339 patients and 351 HC)and five articles on PSD(102 patients and 149 HC)were included.The spontaneous brain activity in the left cerebellar area 9,right middle temporal gyrus and right insula was significantly higher in PSA patients than in HC(P<0.05),while activity in the right cerebellar area 6,left medial superior frontal gyrus(SFGmed),left middle frontal gyrus and right anterior cingulate/paracingulate gyrus was lower(P<0.05).For PSD,spontaneous brain activity was elevated in the right cuneus gyrus and right superior occipital gyrus compared to HC(P<0.05),while it was reduced in the left SFGmed and left inferior pa-rietal lobe(P<0.05).Additionally,spontaneous brain activity in the left medial superior frontal gyrus was lower in both diseases compared to HC(P<0.05).Conclusion The pathological mechanism of PSA may involve a pattern of right-sided compensatory hyperfunction and left-sided inhibitory damage within the language-related network,accompanied by cross-hemispheric synergistic activity of the cerebellum.The occurrence of PSD may be attributed to hyperactivity of the right occipital net-work,and functional inhibition involving the left inferior parietal lobe.The inhibition observed in the left SFG-med(MNI coordinates x=0,y=26,z=44)likely represents the language-emotion integration hub,mediating the co-occurrence of PSA and PSD.
