Objective: To investigate the inhibitory effect of neoeriocitrin (Neo) on ligature-induced experimental periodontitis in mice and evaluate its biosafety, providing experimental evidence for novel candidate drugs in periodontitis treatment. Methods: This study has been approved by the Animal Welfare and Ethical Safety Committee. A periodontitis model was established in C57BL/6J mice using silk ligation. The mice were divided into control, periodontitis model, and three Neo treatment groups (5, 10, 20 mg/kg Neo). After 2 weeks of intervention, alveolar bone resorption was analyzed by micro-computed tomography (micro-CT); periodontal tissue pathological changes were observed via hematoxylin-eosin (HE) and Masson staining; osteoclasts were counted using tartrate-resistant acid phosphatase staining; serum inflammatory factor levels [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), interleukin-10 (IL-10)] were detected by enzyme-linked immunosorbent assay; gut microbiota changes were analyzed by 16S rRNA sequencing; and biosafety was assessed through HE staining of the heart, liver, spleen, lung, kidney, and colon, as well as zonula occludens-1 (ZO-1) immunohistochemical staining of the colon. Results: Compared with the periodontitis model group, the 10 mg/kg Neo treatment group showed significantly alleviated alveolar bone resorption, manifested as reduced cementoenamel junction to alveolar bone crest distance, increased bone mineral density, bone volume fraction, and trabecular thickness. Additionally, reduced inflammatory cell infiltration, improved collagen fiber arrangement, and a significantly decreased number of osteoclasts were observed in periodontal tissues. Serum levels of pro-inflammatory factors TNF-α and IL-6 were also reduced. Furthermore, 10 mg/kg Neo intervention modulated the gut microbiota structure without causing significant multi-organ toxicity or impairing intestinal barrier function. Conclusion Neo can effectively mitigate the progression of experimental periodontitis by inhibiting alveolar bone resorption, reducing periodontal tissue inflammation, modulating systemic immunity, and improving gut microbiota. With good biosafety, Neo is a promising candidate drug for the treatment of periodontitis.

As a type of non-Hodgkin lymphoma,Burkitt lymphoma is characterized by unfixed location of disease,rapid progression,diverse symptoms,and clinical complexity in diagnosis and treatment.Professor Wang Xixing posits that Burkitt lymphoma manifests as a tangible mass,and its formation is associated with the invasion of exogenous pathogens,internal injury induced by seven emotions,and deficiency of healthy qi.The fundamental pathogenesis involves dysfunction of the liver,spleen and kidney,leading to liver qi stagnation,spleen-stomach deficiency in the middle energizer,and liver-kidney disharmony.The secondary manifestations were caused by the binding of phlegm-damp,toxin,and stasis.In general,the pathogenesis of Burkitt lymphoma presented deficiency in the origin and excess in the superficiality,and deficiency interweaved with excess.In clinical practice,Professor Wang emphasizes the regulation of the functions of liver,spleen and kidney,and maintains the body's yin-yang balance on the basis of the combination of disease differentiation and syndrome differentiation.Therapeutic strategies focus on soothing liver qi,replenishing qi to strengthen the spleen,and tonifying the kidney to regulate the liver,separately through the utilization of Chaihu Sanjie Decoction,Buzhong Yiqi Decoction,and Bushen Tiaogan Decoction.In this way,significant clinical efficacy is usually achieved.

Objective To investigate the distribution and evolutionary patterns of traditional Chinese medicine(TCM)syndromes and syndrome elements during the malignant transformation from chronic pancreatitis(CP)to pancreatic intraepithelial neoplasia(Pan IN)and pancreatic ductal adenocarcinoma(PDAC).Methods A retrospective analysis was conducted on 710 patients(330 of CP,104 of Pan IN,276 of PDAC)diagnosed pathologically or clinically at Shanxi Institute of Traditional Chinese Medicine from January 2021 to June 2024.Data including demographics,laboratory results,and TCM diagnostic information were recorded using EpiData 3.1.Syndrome and syndrome-element patterns were determined via factor analysis and K-means clustering using SPSS 27.0.Results The study identifies seven TCM syndrome types in CP,Pan IN,and PDAC.Among CP patients,the syndrome distribution was primarily liver-gallbladder damp-heat syndrome(22.42％)and gastrointestinal excess-heat syndrome(20.91％),with excess syndromes accounting for a higher proportion(43.33％);the syndrome elements were mainly heat(51.52％)and dampness(35.15％),with the disease location in the pancreas,related to the liver,spleen,and stomach.In Pan IN patients,the syndrome distribution was mainly spleen deficiency with dampness obstruction(23.08％)and liver-gallbladder damp-heat syndrome(17.31％),with mixed deficiency-excess syndrome accounting for a higher proportion(30.00％);the syndrome elements were mainly heat(41.35％),dampness(40.38％),and qi deficiency(37.50％),with the disease location in the pancreas,related to the spleen and liver.In PDAC patients,the syndrome distribution was mainly spleen deficiency with dampness obstruction(29.71％)and qi-blood deficiency syndrome(20.29％),with deficiency syndromes accounting for a higher proportion(49.82％);the syndrome elements were mainly qi deficiency(50.00％)and dampness(36.23％),with the disease location in the pancreas,related to the spleen,kidney,and liver.Chi-square tests revealed significant differences in syndrome types(TCM syndromes:x2=100.419,P＜0.001;deficiency-excess syndromes:x2=73.722,P＜0.001),syndrome elements(x2=117.384,P＜0.001),and disease locations(x2=127.191,P＜0.001)across different stages of CP malignant transformation.During CP malignant progression,the proportion of excess syndromes gradually decreased(43.33％→12.32％),while deficiency syndromes increased(26.67％→49.82％).Excess syndrome elements(fire,heat,qi stagnation,blood stasis)decreased(53.48％→25.36％),whereas deficiency syndrome elements(qi deficiency,yin deficiency,yang deficiency,blood deficiency)increased(25.15％→49.64％).The disease location shifted from primarily the liver,spleen,and stomach in the inflammatory stage to the spleen and kidney in the cancerous stage.Conclusion The malignant transformation of CP basically involves the pancreas,is correlated early with liver and spleen-stomach and later with kidney,and exhibits a progression from excess to deficiency in the pattern of"deficiency interweaved with excess syndrome,transition from excess to deficiency,and progressive spleen deficiency".

Periodontitis is a chronic inflammatory and immune reactive disease induced by the subgingival biofilm.The therapeutic effect for susceptible patients is often unsatisfactory due to excessive inflammatory response and oxidative stress.Sinensetin(Sin)is a nature polymethoxylated flavonoid with anti-inflammatory and antioxidant activities.Our study aimed to explore the beneficial effect of Sin on periodontitis and the specific molecular mechanisms.We found that Sin attenuated oxidative stress and inflammatory levels of periodontal ligament cells(PDLCs)under inflammatory conditions.Administered Sin to rats with ligation-induced periodontitis models exhibited a protective effect against periodontitis in vivo.By molecular docking,we identified Bach1 as a strong binding target of Sin,and this binding was further verified by cellular thermal displacement assay and immunofluorescence assays.Chromatin immunoprecipitation-quantitative polymerase chain reaction results also revealed that Sin obstructed the binding of Bach1 to the HMOX1 promoter,subsequently upregulating the expression of the key antioxidant factor HO-1.Further functional experiments with Bach1 knocked down and overexpressed verified Bach1 as a key target for Sin to exert its antioxidant effects.Additionally,we demonstrated that Sin prompted the reduction of Bach1 by potentiating the ubiquitination degradation of Bach1,thereby inducing HO-1 expression and inhibiting oxidative stress.Overall,Sin could be a promising drug candidate for the treatment of periodontitis by targeting binding to Bach1.

Objective:To develop multiplex cytokine detection reagents to analyze expression levels of cytokines,angiogene-sis and bone remodeling proteins in relapse/refractory multiple myeloma(RRMM).Methods:Multiplex bead-based immunoassay by flow cytometry was used to develop quantitative detection reagents of multiplex cytokines,which were applied to detect serum samples from 55 RRMM patients and 22 healthy controls.Expression levels of cytokines,angiogenesis,and bone remodeling proteins in pa-tients,and their correlation with clinical characteristics were analyzed.Results:Detection reagents of 10-plex cytokine immunoassay were successfully developed in this study,with average sensitivity of 7.1 pg/ml,average recovery rate of 97.4%,average intra-assay CV of 4.8%,and average inter-assay CV of 9.0%.In addition,results of RRMM samples found that levels of IL-2,IL-17,DKK1,RANKL and OPG were positively correlated with the level of IgG monoclonal protein,and TIMP1 was positively correlated with levels of IgG and IgA monoclonal protein.Conclusion:In this study,ten kinds of cytokine detection reagents with high sensitivity and speci-ficity are developed,and we found that IL-2,IL-17,DKK1,RANKL,OPG and TIMP1 have potential value in tracking disease pro-gression in RRMM.The established development process of multiplex cytokine reagents has important reference significance for ex-panding the development and application of multiplex detection reagents for protein markers in the future.

Objective:To summarize the clinical and imaging features of pediatric neuroglial heterotopia (NGH) in different locations.Methods:The clinical and preoperative imaging data of 9 patients (6 boys and 3 girls, median age 3 months, range from 1 to13 months) with NGH confirmed by pathology were retrospectively reviewed in Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science and Technology from October 2009 to December 2020. All patients underwent preoperative CT or/and MR examination. Follow-up was performed in 12 to 60 months after operation, with a median follow-up time of 24 months. The location, range, size, density/signal intensity of the lesions were reviewed.Results:Of all 9 cases, three cases were located in nose (2 extranasal type and 1 mixed type), with the maximum diameter of 13, 13 and 15 mm; there were 3 lesions in tongue, all of which were located on the dorsum of tongue, with the maximum diameter of 13, 18 and 23 mm; there were also 2 cases located in nasopharynx, maximum diameter of 15 and 22 mm, respectively. One case was in sacrococcygeal area, with the maximum diameter as 18 mm. All lesions presented as solid masses with well-defined margins, displaying slightly low density compared to grey matter. The CT value ranged from 25 to 47 HU. Compared to grey matter or spinal cord, MRI demonstrated isointense or slight hypointense on T 1WI and slight hyperintense on T 2WI. All masses presented homogenous density or signal intensity, with mild homogenous enhancement. During postoperative follow-up, no recurrence was found in 8 cases. One case of nasal NGH with gradeⅡcleft lip recurred at 1 month follow-up after surgery, and no recurrence was found after the second surgery. Conclusions:The NGH in children has typical imaging features, and is mostly located at the extracranial midline structure.It presents as solid mass, with quasi-circular morphology, well-defined margins and homogeneous density or signal intensity similar to gray matter or spinal cord. The postoperative recurrence rate is low.

Objective:To study the effects of conservative treatment versus percutaneous interventional treatment(PCI)on symptoms and prognosis of chronic coronary syndrome patients aged over 75 years with fractional flow reserve(FFR)in the grey zone(0.75≤FFR≤0.80).Methods:A total of 96 coronary heart disease(CHD)patients aged over 75 years undergone FFR examination in our hospital from January 2011 to December 2017 were retrospectively selected.All patients showed stenosis of 50%-90% in at least one main coronary artery and had FFR values within the range of 0.75-0.80(0.75≤FFR≤0.80). According to the treatment, patients were divided into the optimized medication group(OMT group, n=35)and the PCI group(n=61). The degree of angina alleviation assessed by the Seattle Angina Questionnaire(SAQ)and the incidence of major adverse cardiovascular endpoints(death, myocardial infarction, stroke, and repeated revascularization)were recorded during the one-year follow-up after treatment.Results:There was no significant difference in baseline data including age, gender and comorbidities between the OMT and PCI groups( P>0.05). The incidence of previous myocardial infarction, and the basal level of low-density lipoprotein cholesterol(LDL-C)were higher in the PCI group than in the OMT group( P<0.05). One-year follow-up showed that there was no significant difference between the OMT and PCI groups in the score of SAQ(77.6 ± 19.5 vs. 83.1 ± 22.8, P>0.05)and the incidence of composite MACEs(11.4% or 4 / 35 vs. 9.8% or 6/61, P>0.05). However, the incidence of repeated target vessel revascularization was lower in the PCI group than in the OMT group(1.6% or 1 case vs. 5.8% or 2 cases, P<0.05). Conclusions:In elderly CHD patients aged over 75 years with FFR values between 0.75-0.8 in the grey zone, optimal medication treatment has similar effects as the PCI on symptom alleviation, and no significant increase in composite MACEs is found at one-year follow-up.

Isolated cortical vein thrombosis (ICoVT) is very rare and its clinical symptoms lack specificity.Unlike cerebral venous sinus thrombosis,ICoVT rarely presents increased intracranial pressure and optic disc edema.Imaging examination,especially MRI examination,is very important for the diagnosis of this disease.T2 *-weighted gradient echo sequence and susceptibility-weighted imaging contribute to the early diagnosis of the disease.This article reviews the clinical symptoms,diagnosis,and treatment of ICoVT.
