Pancreaticobiliary maljunction （PBM） is a rare congenital developmental defect of the biliary-pancreatic system characterized by a junction of the pancreatic and bile ducts outside the duodenal wall， forming an extended common channel. This anatomical anomaly compromises the normal function of Oddi’s sphincter， weakens defenses against reflux， and thus triggers a series of biliary and pancreatic complications. Although there is a relatively low incidence rate of PBM， its insidious clinical symptoms often lead to delayed diagnosis， which increases the difficulties in treatment and the risk of poor prognosis. For PBM patients with marked bile duct dilatation， surgical intervention， especially cholecystectomy combined with extrahepatic bile duct resection and bile duct-jejunum Roux-en-Y anastomosis， remains the standard treatment at present. For PBM without marked bile duct dilatation， there are still controversies over related treatment strategies， and most experts are in favor of cholecystectomy， while there is still a lack of consensus on the management of extrahepatic bile ducts， which requires further research and exploration. Endoscopic retrograde cholangiopancreatography （ERCP） is currently the gold standard for diagnosing PBM and assessing pancreaticobiliary abnormalities， and it can not only clarify the nature of lesion， but also collect the bile and biliary duct tissue for pathological examination. ERCP also has the function of interventional treatment， such as stenting， expansion， and drainage， thereby bringing benefits to patients comorbid with biliary neoplasms. However， the application of ERCP in screening is limited by its invasiveness， with increases in technique complexity and the risk of complications in the pediatric population. This article summarizes the definition， classification， pathogenesis， and epidemiological features of PBM and the research advances in current diagnosis and treatment strategies， in order to provide guidance for clinical practice.

Hydrogen-rich water (HRW) shows excellent antibacterial, anti-inflammatory, antioxidant, and wound-healing properties and plays a positive role in the treatment of various diseases, such as brain injury, kidney injury, and periodontitis. Current studies found that HRW can inhibit periodontopathogenic biofilm formation, inhibit oral connective tissue and bone tissue destruction, and show anti-inflammatory and antioxidant properties in periodontitis. Additionally, HRW can alleviate periodontal tissue damage by inhibiting oxidative stress and up-regulating the expression of antioxidant enzymes, such as glutathione peroxidase and superoxide dismutase. HRW exerts anti-inflammatory effects by regulating the nuclear factor erythroid 2-related factor 2 and mitogen-activated protein kinase pathways, which are closely associated with inflammation. Additionally, HRW inhibits the expression of inflammatory cytokines, such as interleukins, inhibits the growth and proliferation of bacterial plaque biofilms, and down-regulates glycosyltransferases and glucan-binding proteins to prevent bacterial adhesion and subsequent development of periodontitis. Furthermore, HRW has a positive effect on the expression of various cell growth factors, α-smooth muscle actin, and type I collagen, which promotes wound healing. Current clinical studies have demonstrated the biological safety of HRW (to a certain extent) and reported no adverse reactions. However, most studies on HRW in oral diseases are preclinical in vivo and in vitro studies. Therefore, further clinical studies are required to validate the therapeutic significance and optimal therapeutic regimen of HRW in human periodontitis. This article aims to review the therapeutic role and the underlying mechanisms of HRW in periodontitis.

OBJECTIVE To investigate α1-adrenergic receptors(α1-AR)distribution in mouse tissues and its function on dexmetomidine(DMED)induced toxic effects.METHODS ① Real-time fluorescence quantita-tive PCR was used to detect the relative expression of α1A-AR,α1B-AR,α1D-AR,α2A-AR,α2B-AR and α2C-AR mRNAs in the heart,apical potion of heart,lungs,apical potion of lung,liver,kidneys,abdominal aorta,prefrontal cortex,hippocampus,striatum,brainstem,thalamus,olfactory bulb,and the rest of the brain tissues of the mouse.The relative expression of mRNA were analyzed.② C57BL/6J mice were pretreated with α2 adrenergic receptor antagonist atipamezole ATI(0.005,0.010,0.020,0.025,0.040,0.050 mg·kg-1,im),orα1-adrenoceptor antagonist prazosin(1 mg·kg-1,im)for 15 min,and then DMED(0.20 mg·kg-1,iv)was given to observe the rate of the loss of righting reflex and the immobilization time in mice.③ C57BL/6J mice were treated with DMED(16.38,20.48,25.60,32.00,40.00,and 50.00 mg·kg-1,iv)to observe the lethality of the mice in 24 h.The dose-effect relationship curves of the lethality rate and the half lethal-dose(LD50)were detected.ATI(1,2,4,and 8 mg·kg-1,im)or prazosin(1 mg·kg-1,im)were pretreated 15 min followed by the administration of DMED(25.60 mg·kg-1,iv).The lethality of the mice were recorded for 24 h.HE staining to observe the lung tissue damage in the mice.RESULTS ① The mRNA expression levels of three α1-AR subtype were higher than those of α2-AR subtype.α2A-AR and α2C-AR were highly expressed in the central nervous system.α2B-AR was highly expressed in the brainstem and peripheral tissues.The mRNA expres-sion levels of α1-AR subtypes were higher than those of α2-AR subtypes in heart,apical potion of heart or lung(P＜0.05).② ATI(0.005 to 0.05 mg·kg-1,im)dose dependently antagonized the loss of righting reflex and decreased the immobilization time induced by DMED(0.20 mg·kg-1,iv).In contrast,prazosin(1 mg·kg-1,im)had no effect on the loss of righting reflex induced by DMED(0.20 mg·kg-1,iv).③ The LD50 of DMED in mice was 26.734 mg·kg-1(iv)with a 95％Cl of 23.606-30.000 mg·kg-1.DMED(25.6 mg·kg-1)was selected for subsequent toxicity.ATI(1,2,4,and 8 mg·kg-1,im)did not antagonize the lethality induced by DMED(25.6 mg·kg-1,iv).The high dose of ATI resulted in elevated death rate and accelerated mortality induced by DMED(25.6 mg·kg-1,iv)in the mice.However,prazosin(1 mg·kg-1,im)reduced the lethality of DMED(25.6 mg·kg-1,iv)(P＜0.01).After administration of DMED(25.6 mg·kg-1),the mice lungs showed significant congestion.HE staining of lung tissues revealed obvious vascular hemorrhage,alveolar rupture,and erythrocyte spillage.Prazosin(1 mg·kg-1,im)effectively attenuated the tissue damage in the lungs,but ATI(1 mg·kg-1,im)aggravated the pulmonary hemorrhage.CONCLU-SIONS In cardiopulmonary tissues,the high expression levels of α1 adrenoceptor overactivation,might related with the lethality induced by DMED.

Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronic immune-mediated disease with uncertain causes. Malnutrition in IBD patients, attributed to factors such as inadequate intake, increased consumption, poor absorption, and bacterial overgrowth in the small intestine, poses a prevalence of 23%–50%, elevating the risk of readmission and mortality while diminishing quality of life. Therefore, urgent implementation of personalized dietary interventions is crucial for enhancing adherence and rectifying malnutrition in IBD patients.

Mastitis is one of the common and prevalent diseases in dairy cows,and the natural prod-uct daidzein is a kind of natural flavonoids with a wide range of pharmacological and anti-inflam-matory effects.However,the effect of daidzein on mastitis in dairy cows has not been reported.Therefore,in this study,we explored the effects of daidzein on LPS-induced inflammatory response and tight junction damage in dairy mammary epithelial cells Firstly,we pretreated the MAC-T cell line using different concentrations of daidzein,and it was clarified that daidzein below 200 μmol/L had no effect on the cell activity.Next,we examined the production of pro-inflammatory mediators in LPS-stimulated MAC-T cell lines using qRT-PCR,and clarified that daidzein could reduce the production of pro-inflammatory mediators in a concentration-dependent manner.Subsequently,af-ter the expression of Occludin,Claudin3 and ZO-1 was detected by immunofluorescence and West-ern Blot,it was clear that daidzein could alleviate MAC-T cell intercellular tight junction injury.Fi-nally,it was demonstrated that daidzein significantly inhibited LPS-induced activation of the NF-κB signaling pathway within MAC-T using network pharmacological analysis and Western Blot.The above results suggest that daidzein can inhibit LPS-induced inflammatory response and tight junc-tion damage in mammary epithelial cells of cows by suppressing the activation of NF-κB signaling pathway.The present study provides a theoretical basis for the alleviation of mastitis by natural products and further expands the pharmacological effects of daidzein.

Objective:To investigate the characteristics of brain network reorganization in migraine patients and its relationship with the grading of right-to-left shunt (RLS) in patent foramen ovale(PFO) by integrated 3.0T structural magnetic resonance imaging (MRI),resting-state functional MRI(fMRI),and contrast-enhanced transthoracic echocardiography, thereby toexplore the mechanism underlying cognitive impairment in migraine.Methods:A total of 49 migraine patients (migraine group)and 16 demographically matched healthy subjects (healthy control group) who received diagnosis and treatment at China-Japan Union Hospital of Jilin University from September 2020 to September 2023 were selected as the study participants. Structural images (T1-weighted) and resting-state functional images were obtained from brain imaging (MRI and fMRI) data. The amplitude of low-frequency fluctuation (ALFF) algorithm was used to quantify the intensity of spontaneous neural activity in brain regions, while the Fazekas scale and the Age-Related White Matter Changes (ARWMC) scale were employed to assess white matter lesions. Participants were evaluated using the Mini-Mental State Examination (MMSE). Based on the results of contrast-enhanced transthoracic echocardiography (cTTE),the migraine group was further subdivided into A1 group (18 cases, no PFO), A2 group (17 cases, PFO with small-to-moderate RLS) and A3 group (14 case, PFO with large RLS) group, the differences in brain functional activity and cognitive function were compared among these groups.Results:By Fazekas scale scores and ARWMC scale scores, the incidence of hyperintense foci in the deep white matter regions in the migraine group were higher than those in the healthy control group: 67.3%(33/49) vs. 6/16, 61.2%(30/49) vs. 5/16, there were statistical differences ( P<0.05). Compared with the healthy control group, the migraine group exhibited higher spontaneous neural activity intensity in the brainstem,bilateral posterior cingulate cortex,left medial frontal gyrus,and left middle frontal gyrus,while showing reduced brain activity in the right angular gyrus region. The short-term delayed recall scores and total MMSE scores in the migraine group were lower than thosein the healthy control group: (1.61 ± 1.06) scores vs. (2.44 ± 0.81) scores, (25.06 ± 2.31) scores vs. (27.94 ± 1.44) scores, there were statistical differences ( P<0.05). The short-term delayed recall scores mong the A1 group, A2 group and A3 group had statistical difference( P<0.05). Conclusions:Migraine patients exhibit specific brain functional network reorganization and cognitive dysfunction, which are closely related to the degree of RLS.
