Gorham-Stout disease(GSD) is a rare osteolytic disorder characterized by spontaneous and progressive osteolysis, along with abnormal angiogenesis and lymphangiogenesis, with no new bone formation. We present a case of a 15-year-old female admitted due to " recurrent right leg pain for 5 years, 11 months after undergoing right femoral fracture surgery". Through comprehensive integration of the patient's clinical phenotype, laboratory tests, imaging findings, pathological examinations, and molecular biological test results, GSD was considered highly likely. A multidisciplinary treatment approach was conducted, including a combination of zoledronic acid and sirolimus to inhibit osteolysis, along with rehabilitation training and orthopedic intervention, providing a personalized and comprehensive treatment strategy.

The patient was a 56-year-old man who presented with abnormal urinalysis findings of over one month’s duration. Serological tests revealed an elevated serum free light chain κ/λ ratio, and immunofixation electrophoresis detected an IgG-κ monoclonal band. Renal biopsy demonstrated membranous nephropathy, with electron-dense deposits observed in the subepithelial space and mesangium on electron microscopy. Immunofluorescence confirmed glomerular deposits of IgG_1/IgG₃-κ. Based on clinical manifestation, bone marrow flow cytology, and lymph node pathology, the patient was diagnosed with small lymphocytic lymphoma (SLL), and membranous nephropathy with light chain-restricted deposition (IgG₁/IgG₃-κ) secondary to SLL. After receiving obinutuzumab treatment, the patient’s proteinuria partially remitted, the lymph nodes significantly shrank, and clinical remission was achieved.

Background: Advances in intensive care have markedly improved survival after severe brain injury, leading to a growing population of patients with prolonged disorders of consciousness (pDOC). Current management of pDOC remains largely supportive, and evidence-based neuromodulatory interventions are limited; moreover, existing guidelines provide insufficiently explicit recommendations regarding mechanisms of action and objective biomarkers of treatment response. Transcutaneous auricular vagus nerve stimulation (taVNS) has emerged as a potential noninvasive intervention; however, its modulatory effects on brain function in pDOC are not yet well characterized, and the paucity of integrative mechanistic evidence has constrained its translation into routine clinical practice. Objectives: Within a multimodal assessment framework, this study aims to systematically elucidate the neurobiological mechanisms by which taVNS modulates brain function and autonomic activity in patients with pDOC, and to evaluate its clinical potential to enhance levels of consciousness. Methods: In this randomized controlled trial, 60 patients with vegetative state/minimally conscious state will be enrolled and randomly allocated to a taVNS group, a transcutaneous nonauricular vagus nerve stimulation group (sham), or a control group (n = 20 per group) for a 4-week intervention. The primary outcome will be changes in the Coma Recovery Scale-Revised scores from baseline to weeks 1, 2, and 4 of treatment. Secondary outcomes will include functional brain activity assessed by electroencephalography and functional near-infrared spectroscopy, as well as autonomic modulation indexed by heart rate variability. Functional prognosis will be evaluated using the Glasgow Outcome Scale-Extended at the end of treatment and at a 6-month follow-up. Safety will be assessed by continuous monitoring and documentation of adverse events throughout the study period. Results and discussion: By integrating electroencephalography–functional near-infrared spectroscopy with heart rate variability, this study will characterize the effects of taVNS on functional brain networks and consciousness recovery in pDOC across complementary behavioral, electrophysiological, hemodynamic, and autonomic domains, while interrogating potential sources of clinical and neurobiological heterogeneity. The findings are expected to provide a mechanistic and evidence-based foundation for the mechanism-driven clinical implementation of taVNS and the optimization of stimulation protocols in pDOC.

Objective: To improve the efficiency of patient treatment in routine, emergency, and mass casualty scenarios (both peacetime and wartime), eliminate reliance on blood type compatibility, and promote the productization of platelet-rich plasma (PRP), this study investigated the optimal mixing ratio for developing a universal PRP formulation. Methods: PRP was prepared from donors with blood types O, A, B, and AB. Samples were mixed in varying proportions, and the optimal ratio was determined based on the trend of anti-A and anti-B antibody titers in the mixed PRP. Concentrations of the growth factors PDGF-AA, PDGF-BB, EGF, TGF-β1, and VEGF were measured by enzyme-linked immunosorbent assay (ELISA) before and after mixing. Results: A mixing ratio of A∶B∶AB=6∶2.5∶24 resulted in no detectable agglutination with either A or B cells in the microcolumn gel system, indicating the absence of immunological reactivity and confirming universal compatibility. Importantly, the levels of all measured growth factors remained unchanged following mixing, suggesting preservation of biological activity. Conclusion: These findings suggest that universal PRP can be prepared by neutralizing blood type antibodies through antigen-antibody reactions.

To study the immunoregulatory effects of lycorine on mice infected with Toxoplasma gondii(T.gondii),BALB/c mice were treated with 20 mg/kg lycorine solution after peritoneal in-fection with T.gondii RH strain.The serum and spleen of mice were collected at the 1st,3rd,5th and 7th day,respectively,and the spleen index of mice was calculated.The proportion of T lympho-cyte subtypes and NK cells were detected in mice by flow cytometry,and the changes of cytokine levels in mice were measured using ELISA kit,so as to evaluate the immunomodulatory effect of lycorine on mice infected with T.gondii.At the same time,the heart,liver,spleen,lungs,and kid-neys of mice were collected at the 7th day,and the pathological changes of the mouse organs were observed through pathological tissue sections,and the amount of the parasite in the liver,lung,kid-ney,and brain of the mice was detected by fluorescence quantitative PCR.The results showed that the survival time of the mice treated with lycorine was significantly extended,and the survival rate reached 80％.The spleen index of mice treated with lycorine was lower than that of the control group.Lycorine up-regulates the ratio of the CD4+T lymphocytes and NK cells in the spleen of mice infected with T.gondii,and helps to improve the ability of mice to resist T.gondii infection.Lycorine can up-regulate the levels of anti-inflammatory cytokine IL-4 and down-regulate the lev-els of pro-inflammatory factors IFN-γ,IL-1β,and IL-9 in serum of mice infected with T.gondii,which is conducive to reducing the damage of inflammatory response and enhancing the ability of anti-T.gondii infection.In addition,lycorine can alleviate the pathological damage of T.gondii to the liver,lungs,spleen,and kidneys of mice,and significantly reduce the amount of the parasite in the lung of mice.The results showed that lycorine could up-regulate the proportion of immune cells CD4+T lymphocytes and NK cells,inhibit the inflammatory response of mice infected with T.gondii,reduce the pathological damage of mice organs,and enhance the ability of mice to resist T.gondii infection,which is expected to become a novel anti-T.gondii drug.

Objective:To explore the effects of quality control circles (QCCs) combined with the strength concept in health education for pediatric leukemia patients.Methods:Totally 185 pediatric leukemia patients admitted to the Children's Hospital of Soochow University from January 2021 to August 2023 were selected as participants by convenience sampling. They were randomly divided into a control group ( n=92) and an observation group ( n=93) based on odd and even numbering. Patients in the control group received standard health education, while those in the observation group underwent QCC-based health education activities incorporating the strength concept. Dietary behavior improvement, treatment adherence, quality of life, and patient satisfaction with nursing care were compared between the two groups before and after the intervention. Results:After the intervention, dietary behavior scores in both groups decreased significantly, with the observation group showing significantly lower scores than the control group ( P<0.05). Treatment adherence and quality of life scores improved significantly in both groups, with the observation group scoring higher than the control group across all dimensions ( P<0.05). Moreover, the observation group demonstrated higher patient satisfaction with nursing care compared to the control group ( P<0.05) . Conclusions:The application of QCC activities combined with health education based on the strength concept effectively improves dietary behavior, treatment adherence, quality of life, and satisfaction with nursing care among pediatric leukemia patients, which is worth promoting in clinical practice.

Objective:To analyze the current status and trend of the mortality burden of cardiovascular disease in China from 2010 to 2021.Methods:Data related to cardiovascular disease mortality and disability-adjusted life year (DALY) were extracted from the Global Burden of Disease Study 2021 (GBD2021) database. The age-standardized mortality rate and DALY rate were calculated, using the 2021 world standard population estimated by GBD2021. Joinpoint 5.2.0 software was used to calculate the mortality rate, standardized mortality rate, DALY rate, standardized DALY rate, annual percent change (APC), average annual percent change (AAPC), and 95% CI of cardiovascular disease in China from 2010 to 2021. Results:The mortality rate of cardiovascular disease was 357.44/100 000, and the age-standardized mortality rate was 280.11/100 000 in China in 2021. The DALY rate was 7 043.33/100 000, and the age-standardized DALY rate was 5 120.06/100 000. From 2010 to 2021, the mortality rate and DALY rate of cardiovascular disease in China showed an upward trend (AAPC was 1.58% and 0.83%, respectively, both P<0.05), and the standardized mortality rate and standardized DALY rate showed a downward trend (AAPC was -2.13% and -2.02%, respectively, both P<0.05). The mortality burden of cardiovascular disease was higher in males (mortality rate 392.80/100 000, DALY rate 8 156.19/100 000) than in females (mortality rate 320.38/100 000, DALY rate 5 876.87/100 000). With the increase older in age, the mortality burden of cardiovascular disease in China decreased first and then increased. China ranked high in the mortality burden of cardiovascular disease among G20 member countries. Conclusions:The death burden of cardiovascular disease is serious in China. The mortality rate and DALY rate of cardiovascular disease in China showed an increasing trend from 2010 to 2021, and the standardized mortality rate and standardized DALY rate of cardiovascular disease ranked high in G20 member countries. The death burden of cardiovascular disease was more serious in men and the elderly. It is necessary to develop more comprehensive prevention, treatment, and rehabilitation measures for men and the elderly to reduce mortality and disability rates, decrease the disease burden, and improve the quality of life.

Objective To review the clinical characteristics of Slackia exigua infections for improving the diagnosis and treatment.Methods We reviewed the clinical characteristics of a case of pulmonary abscess caused by Slackia exigua.The infection cases caused by Slackia exigua were searched and retrieved from PubMed,CNKI,and Wanfang databases,for the articles published during the period from January 1,2011 to December 31,2023.Results Among the 15 cases of Slackia exigua infection,84.6％(11/13)had underlying diseases.Hypertension was the most common underlying disease,reported in 54.5％(6/11)of patients.Fever was present in 73.3％(11/15)of patients.Oral diseases and abscess caused by Slackia exigua were found in 63.6％(7/11)and 60.0％(9/15)of patients,respectively.Mixed infection was identified in 33.3％(5/15)of patients.The bacterium was susceptible to penicillin,ampicillin-sulbactam,ceftriaxone,levofloxacin and clindamycin,but mostly(2/3)resistant to metronidazole.Conclusions Slackia exigua infection often originates from oral aspiration and can cause abscess.Beta-lactam antibiotics are preferred for treatment of Slackia exigua infections.More data are required to confirm whether metronidazole is effective.

Myasthenia gravis(MG)is an autoimmune disease characterized primarily by skeletal muscle weakness and,in severe cases,respiratory involvement.Western medical treatment predominantly relies on immunosuppressants,but long-term administration often leads to notable side effects.In contrast,traditional Chinese medicine(TCM)offers the advantage of multi-target interventions.However,the pathogenesis of MG has not been fully elucidated,and the establishment of animal models that accurately reflect the clinical characteristics of both Chinese and Western medicine is essential for mechanism research and new drug development.This paper systematically reviews the etiology and pathogenesis,diagnostic criteria,and progress of animal model research for MG from both Chinese and Western medicine perspectives.In Western medicine,the pathogenesis of MG is closely related to genetic susceptibility,environmental factors,and autoantibody-mediated postsynaptic membrane damage.In TCM,MG is classified under the category of"flaccidity syndrome",attributed to congenital deficiencies and acquired malnourishment.Western diagnostic criteria involve a combination of clinical symptoms,fatigue testing,serum antibody assays,and electrophysiological evaluation.In contrast,TCM diagnosis emphasizes the integration of primary and secondary symptoms with tongue and pulse pattern differentiation.Currently available animal models mainly include experimental autoimmune myasthenia gravis(EAMG)and passive transfer myasthenia gravis(PTMG).The Toredo acetylcholine receptor(AChR)induced EAMG model aligns well with Western diagnostic criteria,but poorly matches secondary symptoms in TCM.The synthetic AChR peptide model is widely used,but shows low conformity with TCM syndromes.Models induced by muscle-specific tyrosine kinase(MuSK),low-density lipoprotein receptor-related protein 4(LRP4),and transgenic models demonstrate high innovation but exhibit low clinical conformity.Evaluation of these models requires integration of behavioral,electrophysiological,and immunological indicators.However,a systematic framework for modelling TCM syndromes is still lacking.Future research should integrate TCM-based etiological modelling methods with the Western pathological mechanisms to construct disease-syndrome combination models.Additionally,it is crucial to establish a TCM syndrome evaluation system based on"validation by prescription",as well as to improve the scientific rigor and practicality of animal models by the incorporation of emerging technologies.This review provides a theoretical foundation for optimizing MG animal model design,advancing the research on the combination of Chinese and Western medicine,and supporting efficacy assessment and mechanism exploration of Chinese herbal prescriptions.

Objective To construct an animal model of dilated cardiomyopathy(DCM)with heart failure toxin syndrome that conforms to the characteristics of traditional Chinese medicine(TCM)syndrome and identify potential biomarkers or intervention targets for DCM with heart failure toxin syndrome.Methods Fifteen male SD rats were divided into a blank control,doxorubicin,or DCM with heart failure toxin syndrome group using a random number table method,with five rats per group.The doxorubicin group received intraperitoneal injection of doxorubicin at a dose of 1.25 mg/kg,administered on the first and fourth days of each week,along with a standard diet.The DCM with heart failure toxin syndrome group,in addition to the doxorubicin treatment,was given 42％white liquor(10 mL/kg)via gavage every other day,along with a 45％high-fat feed and 10％fructose water.The blank control group received intraperitoneal injection of an equivalent volume of phosphate-buffered saline at the same time points as the doxorubicin group,along with a standard diet.The model was established for 10 weeks.At the fourth and tenth weeks of modeling,echocardiography was performed to measure left ventricular ejection fraction(LVEF),fractional shortening(FS),systolic left ventricular posterior wall thickness(LVPWs),diastolic left ventricular posterior wall thickness,systolic left ventricular internal diameter(LVIDs),and diastolic left ventricular internal diameter(LVIDd);macroscopic changes in fur color of the rats were assessed using the red-green-blue colorimetric method.After modeling,the open field test was conducted to evaluate the exercise tolerance of the rats,and the grip strength test was performed to assess changes in forelimb grip strength.Hematoxylin-eosin,Masson,and wheat germ agglutinin staining were used to evaluate pathological changes in cardiac tissue.Bulk RNA sequencing analysis was performed to identify differentially expressed genes(DEGs)in the hearts of rats between the blank control and the DCM with heart failure toxin syndrome groups.Using DCM,the Blue value of rat fur color,and forelimb grip strength as phenotypic traits,weighted gene co-expression network analysis(WGCNA)was performed to screen for characteristic module gene sets(MEs)associated with DCM with heart failure toxin syndrome.Overlapping analysis was performed on DEGs,immune-related gene sets,and MEs,and the intersecting genes were identified as potential biomarkers or intervention targets for DCM with heart failure toxin syndrome.The sensitivity and specificity of these targets were evaluated using receiver operating characteristic(ROC)curve analysis.Results Compared with the blank control group,at the tenth week of modeling,the LVEF,FS,and LVPWs of rats in the doxorubicin group and the DCM with heart failure toxin syndrome group decreased,whereas LVIDs and LVIDd increased,and the movement distance of the open field test and forelimb grip strength were reduced(P＜0.05).At the 10th week of modeling,the Blue value of fur color in the DCM with heart failure toxin syndrome group was significantly lower than that of the blank control and doxorubicin groups(P＜0.05).Compared with the blank control group,rats in the doxorubicin and DCM with heart failure toxin syndrome groups exhibited significant cardiac dilation and increased immune cell infiltration in cardiac tissue,accompanied by collagen deposition and cardiomyocyte hypertrophy.Bulk RNA sequencing identified 2,003 DEGs,including 1,082 downregulated genes and 921 upregulated genes.WGCNA results revealed that the MEturquoise module had the strongest positive correlation with DCM and the strongest negative correlation with the Blue value and forelimb grip strength.The overlapping analysis identified four intersecting genes:bone morphogenetic protein 6(Bmp6),serine-threonine-protein kinase 1(Pak1),proto-oncogene JunD(JunD),and S100 calcium-binding protein A3(S100A3).ROC curve analysis demonstrated that these four genes exhibited high sensitivity and specificity for DCM with heart failure toxin syndrome.Conclusion The rat model constructed by intraperitoneal injection of doxorubicin combined with a high-fat feed,fructose water,and white liquor gavage closely aligns with the characteristics of the DCM with heart failure toxin syndrome.Bmp6,JunD,Pak1,and S100A3 are potential biomarkers or therapeutic targets for DCM heart failure toxin syndrome.
