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.

Endoscopic full-thickness resection (EFTR) is a minimally invasive technique that is increasingly used for gastrointestinal stromal tumors (GISTs) originating from the muscularis propria. Despite its advantages over conventional surgery, such as complete tumor resection and faster recovery, EFTR faces challenges related to its efficacy, safety, and feasibility, particularly in gastric GISTs. By summarizing the literature published over the past decade, this review provides a comprehensive overview of the clinical outcomes of EFTR and the evolution of defect closure devices.

ObjectiveThe quality of fresh Gastrodiae Rhizoma directly determines the efficacy of its terminal products. According to the theory of excellent shape， high quality， and superior effect of authentic medicinal materials， this study aimed to develop a novel quality evaluation system for fresh Gastrodiae Rhizoma by systematically quantifying and integrating appearance traits with bioactive components. MethodsFresh Gastrodiae Rhizoma samples were collected from four major producing regions. After herbal textural research and a literature review， tuber weight， width， length， and aspect ratio were selected as quantitative indicators of appearance， and they were measured by an electronic balance and a digital vernier caliper. Key active components， including gastrodin， p-hydroxybenzyl alcohol， parishins， and total polysaccharides， were quantified via ultra performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） and the phenol-sulfuric acid method. Descriptive statistics and K-means clustering analysis were employed to establish the threshold ranges for the excellent shape and high quality indicators. ResultsTwo specific quantitative evaluation systems for characterizing the excellent shape and high quality of fresh Gastrodiae Rhizoma were established. System 1： tuber weight > 83.90 g， tuber width > 3.50 cm， total gastrodin and p-hydroxybenzyl alcohol content > 0.277%， and total parishin content > 0.561%. System 2： tuber length < 9.89 cm， aspect ratio < 3.41， and total polysaccharide content > 195.274 mg·g^-1. The verification results showed that the systems effectively identified fresh Gastrodiae Rhizoma samples with both excellent appearance features and stable bioactive components. ConclusionThis study establishes a multi-dimensional evaluation and grading system for fresh Gastrodiae Rhizoma based on the correlation between shape and quality. This framework provides a scientific basis for the quality control and resource grading of fresh Gastrodiae Rhizoma and lays a methodological foundation for the efficient utilization of both the medicinal and edible value of this herbal medicine.

A 44-year-old male presented with a 19-year history of urinary calculi and a 1-year history of polydipsia and weight loss. Laboratory tests revealed hyperparathyroidism and evidence of glucagonoma-associated diabetes. Imaging studies identified masses in the pancreatic head and body/tail, suggestive of glucagonoma and a parathyroid adenoma. Furthermore, the patient exhibited hypercalcitoninemia and elevated cortisol and adrenocorticotropic hormone levels. Genetic testing revealed a heterozygous MEN1 mutation [c.65T>G (p.Leu22Arg)], confirming the diagnosis of multiple endocrine neoplasia type 1 (MEN-1). The patient subsequently underwent near-total parathyroidectomy and total pancreatectomy. Postoperative immunohistochemical staining of the pancreatic tail tumor was positive for glucagon and calcitonin. The patient′s postoperative hormone levels (calcitonin, glucagon, adrenocorticotropic hormone, cortisol) normalized, suggesting a rare pancreatic neuroendocrine tumor (pNET) that was co-secreting multiple hormones. Postoperative management included pancreatic enzyme supplementation, calcium supplementation, vitamin D supplementation, and insulin for glycemic control. Follow-up evaluations at 10 months demonstrated a stable clinical condition, well-controlled blood glucose and biochemical parameters, and an acceptable quality of life. This case study highlights that the presence of pNETs should be considered in patients with MEN-1 and multiple abnormal hormone levels. Timely surgical management of the involved glands and postoperative complications can effectively improve prognosis.

As population aging intensifies,stroke incidence is rising yearly.Complicated with neurological impairment,this condition often leads to motor dysfunction,affecting walking stability and coordination and severely impacting the patient's daily life and mental state.In recent years,digital technology-assisted walking rehabilitation training has shown great potential in post-stroke rehabilitation.By integrating modern digital technolo-gies such as virtual reality,intelligent feedback systems,and remote rehabilitation,this approach not only provides personalized rehabilitation plans but also promotes the recovery of walking function through immersive training,real-time feedback,and remote monitoring.This article reviews the application status,effectiveness,and limita-tions of digital-technology-assisted walking rehabilitation for post-stroke hemiplegic patients.It aims to clarify the new direction of post-stroke walking training and explore more effective rehabilitation methods to help patients regain their walking ability.

Objective:To investigate the enhancement effect of deep progressive reconstruction (DPR) algorithm on image quality and standardized uptake value (SUV) of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in obese patients. Methods:The images of a total of 27 obese patients,who underwent 18F-FDG PET/CT in Affiliated Nanjing Hospital of Nanjing Medical University from September 2023 to May 2024,were retrospectively enrolled. The images of all patients were collected by using uMI 780 PET/CT. Ordered subset expectation maximization (OSEM) iterative algorithm and DPR algorithm were adopted to reconstruct PET images,and measure counting rate of scattering coincidence of PET/CT images,counting rate of true coincidence,noise equivalent counting rate (NECR) and scattering fraction (SF). The quality indicators of PET images included signal-to-noise ratio (SNR),the maximum SUV (SUVmax) of lesions,the tumor-to-background ratio (TBR),the contrast-to-noise ratio (CNR) and the visual scores of 18F-FDG PET/CT images on livers were evaluated. The differences and consistency of various indicators between DPR and OSEM reconstruction algorithms were further analyzed. Results:The average 18F-FDG PET/CT injection activity of 27 patients was (0.12±0.01) mCi (1 mCi=37 MBq)/kg,and the counting rate of true coincidence,NECR and SF of PET images were respectively (153.73±25.09),(44.81±8.47) kcps and (36.77±1.91)％. The SNR of liver obtained by DPR algorithm was (15.83±3.60),which was significantly higher than that (9.06±1.87) of OSEM algorithm,with statistically significant (t=20.6,P<0.05),and there was significantly correlation in liver SNR between two algorithms (R2=0.91,P<0.05). In 27 uptake 18F-FDG PET/CT lesions,the SUVmax,TBR and CNR of lesions that were obtained from OSEM algorithm were respectively (5.86±1.49),(1.95±0.49) and (17.74±4.77),which were lower than corresponding those of DPR algorithm,and the differences were significant (t=9.03,8.79,15.49,P<0.05),respectively. There were significant correlations in SUVmax,TBR and CNR between the two algorithms (R2=0.71,0.70,0.76,P<0.05),respectively. The visual scores of PET images obtained from the DPR algorithm was 4 (3,5) scores,which was significantly higher than 3 (2,4) scores of OSEM algorithm,and the difference of that between two algorithms was significant (U=396,P<0.05). Conclusion:The scattering effect of 18F-FDG PET/CT imaging is stronger in obese patients,whose counting rate of equivalent effect of noise is lower. The DPR reconstruction algorithm can significantly improve the SNR and lesion contrast of PET images than the OSEM algorithm,which has significant gain effect on the SUVmax of lesions,and it can significantly improve the quality of 18F-FDG PET/PET images in obese patients.

Objective:To explore the value of serum P-selectin,Interleukin-18(IL-18),and Homocysteine(Hcy)levels in predicting the adverse outcomes of interventional therapy in elderly patients with deep vein thrombosis(DVT)in the lower extremities.Methods:A total of 165 elderly patients with DVT from January 2020 to August 2023 were se-lected.All patients underwent transcatheter intervention thrombolysis therapy.Patients were divided into good outcome group and poor outcome group according to the clinical treatment outcome.Serum P-selectin,IL-18,and Hcy levels were compared between the two groups.The correlation between serum P-selectin,IL-18,and Hcy levels and disease indicators,as well as the outcomes of interventional therapy was analyzed.The predictive value of serum P-selectin,IL-18,and Hcy levels for the outcomes of interventional therapy was evaluated.Results:The total effective rate of catheter-based interventional thrombolysis in 165 patients was 81.82%(135/165).The patients with good outcomes were included in the good outcome group,and the patients with poor outcomes were included in the poor outcome group.The difference in circumference between the affected side and the healthy side of the thigh and the difference in circumference between the affected side and the healthy side of the calf in the poor outcome group were greater than those in the good outcome group(P<0.05).The levels of serum P-selectin,IL-18,and Hcy in the poor outcome group were higher than those in the good outcome group(P<0.05).The levels of serum P-selectin,IL-18,and Hcy were posi-tively correlated with the difference in circumference between the affected and healthy thighs and the difference in cir-cumference between the affected and healthy calves,and negatively correlated with the outcome of interventional therapy(P<0.05).Before and after correcting other factors,serum P-selectin,IL-18,and Hcy were all independent risk factors for the outcome of interventional therapy in elderly patients with DVT(P<0.05).The area under the curve(AUC)of serum P-selectin,IL-18,and Hcy for predicting the outcome of interventional therapy for elderly DVT was 0.789(95%CI:0.718-0.848),0.812(95%CI:0.744-0.868),and 0.792(95%CI:0.722-0.851),respectively.The cutoff values were 44.21 ng/mL,185.73 ng/L,and 23.60 μmol/L,with sensitivities of 70.00%,70.00%,and 80.00%,and specificities of 82.22%,82.96%,and 68.15%,respectively.The AUC of the combined prediction of the outcomes of interventional therapy for elderly DVT was 0.935(95%CI:0.886-0.967),with a cutoff value of 44.08 ng/mL,185.16 ng/L,and 23.37 μmol/L for the three variables,with a sensitivity of 86.67%and a specificity of 88.15%.This was significantly better than the individual prediction values of the three variables(Z=5.817,4.753,5.206,all P<0.001).Conclusion:Serum P-selectin,IL-18,and Hcy are significantly correlated with disease indicators and interventional treatment outcomes in el-derly patients with DVT,and can effectively predict the outcome of interventional treatment,with a high combined pre-dictive value.

Objective:To analyze the epidemiological characteristics of mumps in China under the immunization strategies of different doses of mumps-containing vaccines(MuCV) by analyzing the national mumps surveillance data from 2020 to 2023.Methods:Based on the national mumps surveillance data from 2020 to 2023, a comparative analysis was conducted on the mumps incidence and the distribution characteristics of mumps cases in time, region and population in the three different periods of 2004-2007 (without MuCV implementation), 2008-2019 (one-dose MuCV implementation) and 2020-2023 (two-dose MuCV implementation) in China.Results:From 2020 to 2023, the annual incidence rate of mumps was 6.48-9.20/100 000, and the annual number of reported cases was 91 303-129 120 cases. After the implementation of the 2-dose MuCV immunization strategy, the epidemiological characteristics of mumps in China have changed to some extent. Compared with the period of 2004-2007 and 2008-2019, the traditional seasonal epidemic pattern of mumps disappeared from 2020 to 2023, with no obvious epidemic peak throughout the year. There was no significant regional difference in the incidence of mumps. Children and adolescents under 15 years of age were the main population of mumps (accounting for 85.46%), of which children aged 5-9 years accounted for 45.07%. Compared with the period of 2004-2007 and 2008-2019, the proportion of mumps cases in the 0-4 years old group showed an increasing trend, the proportion of mumps cases in the 10-14 years old group showed a decreasing trend, and the proportion of adult cases over 40 years old also increased from 2020 to 2023. The age group with the highest incidence of mumps was found to have shifted from 7 years old to 4 years old.Conclusions:The 2-dose MuCV immunization strategy has effectively reduced the incidence of mumps in China. It is necessary to strengthen the surveillance of mumps in kindergartens and primary school children.
