Tuberculosis (TB), a chronic infectious disease caused by Mycobacterium tuberculosis, is primarily airborne and remains a global health problem, especially in resource-limited countries and regions. The emergence of drug resistance in M. tuberculosis has rendered the existing means ineffective in the treatment of TB. Therefore, research in new therapeutic directions has become imperative. In this review, we outline functional peptides in terms of the mechanisms of action, anti-TB attempts, advantages and disadvantages, and latest advances, aiming to analyze the research progress in anti-TB peptides. Furthermore, we investigate the potential applications of bioactive compounds found in traditional Chinese Medicine within the context of peptides.

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.

Objective:To evaluate the value of ultrasound radiomics combined with machine learning for early diagnosis of seronegative Hashimoto’s thyroiditis (SN-HT) .Methods:This retrospective study included 164 patients from Liaoning Provincial People’s Hospital , Lixin County People’s Hospital, Linghai Dalinghe Hospital, Fengcheng Phoenix Hospital, who underwent thyroidectomy for solitary nodules with normal thyroid function between Nov. 2016 and Jan. 2024. Postoperative pathology confirmed Hashimoto’s thyroiditis (HT) in some cases, who were further categorized into antibody-positive and antibody-negative groups based on serum antibody status. Patients without Hashimoto’s thyroiditis served as the control group. A total of 298 ultrasound images were analyzed. Radiomics features were extracted from hypoechoic non-nodular areas within 0.5 cm surrounding the tumor. Two senior pathologists and two senior ultrasound physicians independently assessed lymphocytic infiltration, eosinophilic changes of follicular epithelium, and the proportion of hypoechoic areas in pathology and ultrasound images, respectively. A machine learning model, CCH-NET, was developed using linear regression and t-distributed stochastic neighbor embedding (t-SNE) techniques. The dataset was divided into a training set (80%) and a validation set (20%) to compare the diagnostic accuracy of CCH-NET with that of senior ultrasound physicians. Results:In internal validation, CCH-NET achieved a diagnostic accuracy of 88.89% for both antibody-positive and antibody-negative groups, significantly higher than the 66.67% accuracy of senior ultrasound physicians ( P<0.01). In external validation, CCH-NET achieved 75.00% and 66.67% accuracy for the two groups, compared to 50.00% by senior ultrasound physicians. For the control group, both methods achieved 93.33% accuracy. The AUC of CCH-NET was 0.848, outperforming senior ultrasound physicians (0.681) ,demonstrating superior diagnostic performance. Conclusion:The radiomics-based CCH-NET model, using non-nodular hypoechoic areas as a specific indicator, can accurately identify early SN-HT in euthyroid patients. It significantly outperforms senior ultrasound physicians, improving diagnostic accuracy and reducing missed diagnoses.

Objective To observe the effects of electroacupuncture auricular acupuncture points on depression-like behaviors and ventral dorsal tegmental area(VTA)TH,DRD1 and DRD2 induced in well acute stress disorder(ASD)mice.Methods Experiment 1:18 male C57 mice were divided into 9 control and 9 model mice.Behavioural paradigms such as forced swimming test(FST)and tail suspension test(TST)were used to detect depression-like behaviors in the mice starting on day 5 and day 36;double-labelled staining for immediate early gene protein(C-Fos)and tyrosine hydroxylase(TH)was detected in the VTA of the mice by immunofluorescence.Experiment 2:45 male C57 mice were divided into 15 mice each in the control groups,model groups and electroacupuncture groups.30 days after completion of the electroacupuncture intervention,the mice were tested for depressive behaviors using behavioural paradigms such as FST and TST;dopamine receptor D1(DRD1)and dopamine receptor D2(DRD2)was detected in the VTA of mice in each group using fluorescence quantitative PCR and Western blot techniques;the number of TH neurons in the brain area of the VTA of mice was observed by immunofluorescence.Results Experiment 1:Compared with the control group,the immobile duration of the model group increased in the TST(P<0.001)and FST(P<0.001)on day 5 and day 6,and the immobile duration of the model group increased in the TST(P<0.01)and FST(P<0.01)on day 36 and day 37;compared with the control group,the number of C-Fos and TH fluorescence double-labelled neurons in the model group increased(P<0.05).Experiment 2:At day after completion of the electroacupuncture intervention,the immobile duration of TST(P<0.01)and FST(P<0.01)were decreased in the electroacupuncture group compared with the model group;compared with the control group,DRD1 mRNA(P<0.001)and protein expression(P<0.01)were increased in the VTA of the electroacupuncture group,and DRD2 mRNA(P<0.001)and protein expression(P<0.05)were decreased,TH protein expression(P<0.05)increased,and the number of TH neurons increased(P<0.01).Conclusion Early intervention with auricular electroacupuncture points has an ameliorative effect on depression-like behaviors induced by acute stress disorder in mice,which may be achieved by modulating the activity level of dopaminergic neurons and the expression level of DRD1 and DRD2 in the VTA.

Distal transradial access(dTRA)was first applied in coronary heart disease intervention by Kiemeneij in 2017,dTRA has become an important technological advancement of coronary interventional therapy.This approach,performed by puncturing the distal radial artery within the anatomical snuffbox or Hegu point,significantly reduces the incidence of radial artery occlusion compared with conventional transradial access and shortens compression time to 2-3 hours after procedure.Clinical evidence confirms the efficacy of dTRA in facilitating complex percutaneous coronary interventions,including stenting of left main coronary artery bifurcation lesions and recanalization of chronic total occlusions.Its application has progressively expanded to neurointerventional procedures(cerebral angiography),tumor embolization(transarterial chemoembolization for hepatocellular carcinoma),and peripheral vascular interventions.Despite increasing clinical adoption,dTRA still faces challenges,including a long learning curve and relatively lower initial puncture success rates.Combined with the current paucity of robust evidence-based data,the viability of dTRA as a routine interventional access route remains a subject of debate.This article systematically reviews the anatomical landmarks,clinical advantages,limitations,and multidisciplinary applications of dTRA.This article aims to provide practical guidance for interventionalists and promote the standardization of this technique in daily clinical practice.
