Objective:To compare the effects of manual acupuncture(MA),electroacupuncture(EA),and moxibustion on knee joint cartilage morphology,serum inflammatory factors interleukin(IL)-6 and IL-10,matrix metalloproteinase 13(MMP13),and intestinal flora composition in knee osteoarthritis(KOA)model rats.Methods:Forty male specific-pathogen-free Sprague-Dawley rats aged seven weeks were randomly divided into a normal group(n=8)and a KOA modeling group(n=32).The KOA model was established using sodium iodoacetate induction.The KOA modeling rats were further randomly divided into a model group,an MA group,an EA group,and a moxibustion group,with 8 rats in each group.In the MA,EA,and moxibustion groups,interventions targeting the right Futu(ST32)and Zusanli(ST36)were performed for 15 min,once every other day,for 14 sessions.The normal and model groups were bundled on the self-made fixation frame for 15 min.The rat knee joint diameter was measured on the 8th day of adaptive feeding,after successful modeling,and after the 14th intervention.Lequesne behavioral scoring was performed after successful modeling and after the 14th intervention.After the 14th intervention,hematoxylin-eosin(HE)staining and Masson staining were performed with the cartilage sections of the right knee joint.The pathomorphological changes of the rat joint cartilage were observed and quantified by Mankin's score.Enzyme-linked immunosorbent assay was used to detect the rat serum levels of IL-6,IL-10,and MMP13.Additionally,16S rDNA sequencing was used to detect the composition of rat fecal flora.Results:Compared to the normal group,the right knee joint diameter and the Lequesne score were significantly increased in the model group(P<0.01).Compared to the model group,the right knee joint diameter and the Lequesne score of rats in the MA,EA,and moxibustion groups were significantly reduced(P<0.01),with no significant differences among the three intervention groups(P>0.05).HE staining and Masson staining revealed disordered cartilage structure in the model group,which was improved following interventions in the MA group,EA group,and moxibustion group.Mankin's score was significantly higher in the model group versus the normal group(P<0.05)while significantly lower in the MA,EA,and moxibustion groups versus the model group(P<0.05).Serum analysis showed elevated IL-6 and MMP13 levels and reduced IL-10 level in the model group versus the normal group(P<0.05).Compared to the model group,the serum IL-6 level was significantly reduced(P<0.05),and the IL-10 level was significantly increased(P<0.05)in the MA,EA,and moxibustion groups,but without statistical differences among the three intervention groups(P>0.05);moreover,the MMP13 level in the moxibustion group was significantly lower than that in the model group(P<0.05).The alpha diversity analysis of intestinal flora showed no statistical difference in the number of operational taxonomic units(OTUs)and alpha diversity index among groups(P>0.05).Intestinal flora beta diversity analysis revealed significant differences among groups(P<0.05).Intestinal flora composition analysis showed significantly increased relative abundance of Lactobacillus(P<0.05)and significantly decreased relative abundance of Eubacterium_coprostanoligenes(P<0.05)in the model group compared to the normal group;compared to the model group,the relative abundances of Firmicutes,Lactobacillus,and Romboutsia in the MA,EA,and moxibustion groups were significantly reduced(P<0.05);the relative abundance of Bacteroidetes and Lachnospiraceae_NK4A136 in the MA group increased significantly(P<0.05);Bacteroidetes and Ruminococcaceaae_UGC-005 increased significantly in the moxibustion group(P<0.05).Conclusion:MA,EA,and moxibustion effectively reduced knee joint swelling,improved cartilage tissue morphology,optimized intestinal flora composition,down-regulated expression levels of serum pro-inflammatory factors IL-6 and MMP13,and increased expression level of anti-inflammatory factor IL-10 in KOA rats.Among them,moxibustion exhibited the most obvious regulatory effect on inflammatory factors.

Objective To summarize and analyze the clinical features,imaging manifestations,pathological characteristics,treatment approaches,and prognosis of adrenal anastomotic hemangioma(AH),so as to enhance the clinical understanding of this disease.Methods A retrospective analysis was conducted on 3 adrenal AH patients treated in Tongji Hospital during Jan.2012 and Dec.2024.Relevant literature was reviewed.Results All patients were male,aged 34-56 years,with a maximum tumor diameter of 2.0-5.0 cm.All tumors were solitary.No patients presented with special clinical manifestations.Biochemical tests indicated tumors with no endocrine function.Contrast-enhanced computed tomography showed circular mixed density shadows with uneven edge enhancement.Two patients underwent laparoscopic partial adrenal resection,and one patient received robot-assisted laparoscopic partial adrenal resection.Postoperative pathological results of all three cases indicated AH.Immunohistochemistry showed CD31(+),CD34(+),and ERG(+).No recurrence was found in a postoperative follow-up of 1-45 months.A total of 22 cases of adrenal AH were reported in the literature and our center,with onset age ranging from 34 to 83 years.The patients included 17 males and 5 females,with a maximum tumor diameter of 0.6-8.8 cm.Among them,2 cases were multifocal and the tumors were located in the kidneys,beside kidneys,or in the inferior vena cava.Two cases showed clinical manifestations of lower back pain.During the follow-up of 156 months,no recurrence or metastasis was observed.Conclusion Adrenal AH is a rare benign tumor,which mainly occurs in middle-aged and elderly people with no clinical symptoms and endocrine function.Imaging can easily mistake it for pheochromocytoma or well differentiated vascular sarcoma,and the diagnosis mainly relies on pathological examination.It should be distinguished from pheochromocytoma and well differentiated vascular sarcoma.Surgery is the main treatment method and the prognosis is good.

Objective To explore the potential categories of health risk behaviors among students aged 11 to 18 years in Minhang District,Shanghai in order to identify the influencing factors of health risk behaviors among different categories of students.Methods Using stratified cluster sampling techniques,a random selection of 1 690 middle school students from Minhang District,Shanghai,were chosen as the study sample.Data was collected using the"Shanghai Adolescent Health-Related Behavior Survey Questionnaire"to assess participants'scores on six categories of health risk behaviors.Latent profile analysis(LPA)was employed to cluster students'health risk behaviors,and a multifactorial Logistic regression model was used to analyze the related influencing factors.Results The health risk behaviors of students aged 11 to 18 in Minhang District,Shanghai,were categorized into 3 groups:Class 1,comprising 915 students(54.14%),with moderate to low scores in health risk behaviors,named"the group with moderately low levels of various health risk behaviors";Class 2,comprising 539 students(31.89%),with higher scores in psychological addiction,named"the group with psychological addiction as the prominent health risk behavior";Class 3,comprising 236 students(13.97%),with higher scores in substance addiction,named"the group with substance addiction as the prominent health risk behavior".The results of the univariate analysis for the three potential categories of student health risk behaviors show that there are statistically significant differences in the 3 potential categories of health risk behaviors among students of different schools,ages,ethnicities,and boarding situations(P<0.05).The analysis results of the multivariate Logistic regression indicate that compared to junior high school students,both senior high school students and vocational high school students have a higher risk of exhibiting unhealthy behaviors characterized by psychological addiction and substance addiction,with all differences being statistically significant(P<0.05).Conclusion The latent profile analysis reveals three distinct categories of health risk behaviors among students aged 11 to 18 years in Minhang District,Shanghai,with significant distribution differences among students from diverse backgrounds.Consequently,it is recommended that tailored health education and intervention measures be implemented for students with different school characteristics and at various educational stages.

Objective:To investigate the effects of moxibustion,filiform needle acupuncture,and electroacupuncture on synovial hypoxia and expression of synovial fibrosis markers[transforming growth factor(TGF)-β and collagen alpha-1(Ⅰ)chain(COL1A1)]in knee osteoarthritis(KOA)rats.Methods:Fifty Sprague-Dawley rats were randomly divided into a normal group,a model group,a moxibustion group,an acupuncture group,and an electroacupuncture group,with 10 rats in each group.Except for the normal group,rats in the other four groups were injected with sodium iodoacetate into the right knee joint cavity to establish KOA models.The right Futu(ST32)and Zusanli(ST36)were selected in the moxibustion,acupuncture,and electroacupuncture groups to perform the mild moxibustion with moxa sticks,filiform needle acupuncture,or electroacupuncture,respectively.Each intervention lasted 15 min,once every other day,and continued for 4 weeks,with a total of 14 interventions.The Lequesne score was used to evaluate the degree of knee dysfunction before and after intervention,and the rat's right knee joint diameter was measured to evaluate the degree of knee swelling.Morphological changes of the right knee joint synovial tissue were observed using hematoxylin-eosin staining.Hypoxia probe immunofluorescence staining was used to observe the degree of synovial hypoxia in rats.Western blotting was used to detect the protein expression levels of hypoxia-inducible factor(HIF)-1α,TGF-β,and COL1A1 in the synovial tissue of the right knee joints.Results:Before intervention,the Lequesne score and the right knee joint diameter in the other four groups increased significantly compared to the normal group(P<0.01).After intervention,the Lequesne score and the right knee joint diameter increased significantly in the model group compared to the normal group(P<0.01)together with worsened cartilage deformation and osteophytes,inflammatory cell infiltration and fibrosis in synovial tissue,and hypoxia degree,and the expression levels of HIF-1α,TGF-β,and COL1A1 proteins in the knee joint synovial tissue of rats increased(P<0.01).The Lequesne score and the right knee joint diameter decreased significantly(P<0.01 or P<0.05),the cartilage morphology was normal without obvious osteophytes,and the hypoxia degree reduced in the three intervention groups compared to the model group.Among them,the moxibustion group had the most notable improvement in hypoxia,synovial tissue fibrosis,angiogenesis,and inflammatory cell infiltration.The expression levels of HIF-1α,TGF-β,and COL1A1 proteins decreased in the moxibustion and electroacupuncture groups(P<0.01),and the expression levels of HIF-1α and TGF-β proteins were decreased in the acupuncture group(P<0.01).Conclusion:Moxibustion,filiform needle acupuncture,and electroacupuncture improve knee joint function and reduce knee joint swelling in KOA rats.The mechanism may be to improve synovial fibrosis of the knee joint by regulating HIF-1α;moxibustion has the best effect on improving hypoxia among the three interventions,but the effect of filiform needle acupuncture on COL1A1 is not significant.

ObjectiveTo develop a nomogram-based risk prediction model for chronic obstructive pulmonary disease (COPD) incidence among the community-dwelling population aged 40 years old and above, so as to provide targeted references for the screening and prevention of COPD. MethodsBased on a natural population cohort in suburban Shanghai, a total of 3 381 randomly selected participants aged ≥40 years underwent pulmonary function tests between July and October 2021. Cox stepwise regression analysis was used to develop overall and gender-specific risk prediction models, along with the construction of corresponding risk nomograms. Model predictive performance was evaluated using the C-indice, area under the curve (AUC) values, and Brier score. Stability was assessed through 10-fold cross-validation and sensitivity analysis. ResultsA total of 3 019 participants were included, with a median follow-up duration of 4.6 years. The COPD incidence density was 17.22 per 1 000 person-years, significantly higher in males (32.04/1 000 person-years) than that in females (7.38/1 000 person-years) (P<0.001). The overall risk prediction model included the variables such as gender, age, education level, BMI, smoking, passive smoking, and respiratory comorbidities. The male-specific model incorporated the variables such as age, BMI, respiratory comorbidities, and smoking, while the female-specific model included age, marital status, respiratory comorbidities, and pulmonary tuberculosis history. The C-indices for the overall, male-specific, and female-specific models were 0.829, 0.749, and 0.807, respectively. The 5-year AUC values were 0.785, 0.658, and 0.811, with Brier scores of 0.103, 0.176, and 0.059, respectively. Both 10-fold cross-validated C-indices and sensitivity analysis (excluding participants with a follow-up duration of <6 months) yielded C-indices were above 0.740. ConclusionThis study developed concise and practical overall and gender-specific COPD risk prediction models and corresponding nomograms. The models demonstrated robust performance in predicting COPD incidence, providing a valuable reference for identifying high-risk populations and formulating targeted screening and personalized management strategies.

BACKGROUND: The primary limitation to kidney transplantation is organ shortage. Recent progress in gene editing and immunosuppressive regimens has made xenotransplantation with porcine organs a possibility. However, evidence in pig-to-human xenotransplantation remains scarce, and antibody-mediated rejection (AMR) is a major obstacle to clinical applications of xenotransplantation. METHODS: We conducted a kidney xenotransplantation in a brain-dead human recipient using a porcine kidney with five gene edits (5GE) on March 25, 2024 at Xijing Hospital, China. Clinical-grade immunosuppressive regimens were employed, and the observation period lasted 22 days. We collected and analyzed the xenograft function, ultrasound findings, sequential protocol biopsies, and immune surveillance of the recipient during the observation. RESULTS: The combination of 5GE in the porcine kidney and clinical-grade immunosuppressive regimens prevented hyperacute rejection. The xenograft kidney underwent delayed graft function in the first week, but urine output increased later and the single xenograft kidney maintained electrolyte and pH homeostasis from postoperative day (POD) 12 to 19. We observed AMR at 24 h post-transplantation, due to the presence of pre-existing anti-porcine antibodies and cytotoxicity before transplantation; this AMR persisted throughout the observation period. Plasma exchange and intravenous immunoglobulin treatment mitigated the AMR. We observed activation of latent porcine cytomegalovirus toward the end of the study, which might have contributed to coagulation disorder in the recipient. CONCLUSIONS 5GE and clinical-grade immunosuppressive regimens were sufficient to prevent hyperacute rejection during pig-to-human kidney xenotransplantation. Pre-existing anti-porcine antibodies predisposed the xenograft to AMR. Plasma exchange and intravenous immunoglobulin were safe and effective in the treatment of AMR after kidney xenotransplantation.

Objective To explore the expression of epidermal growth factor and nuclear transcrip-tion factor kappa B(NF-κB)in elderly gliomas and their roles in malignant progression of the dis-ease.Methods A total of 240 elderly glioma patients undergoing surgical resection in our hospital from January 2020 to January 2023 were enrolled and served as an observation group.Another 100 patients receiving surgical treatment due to traumatic brain injury in our hospital during the same period were recruited and served as the control group.Immunohistochemical assay was used to detect the expression of epidermal growth factor and NF-κB in brain tissue.Cox regression analy-sis was employed to determine the independent influencing factors of malignant progression in the elderly glioma patients.Results The observation group had significantly higher epidermal growth factor expression score and NF-κB expression score than the control group(7.44±1.16 vs 3.68±0.51,6.49±1.02 vs 3.56±0.64,P＜0.01).The age,tumor pathological grade,surgical approach,postoperative radiotherapy,and epidermal growth factor and NF-κB expression levels were inde-pendent factors affecting the progression of elderly glioma patients(P＜0.05,P＜0.01).Conclusion The epidermal growth factor and NF-κB expression levels are independent influen-cing factors of progressive disease in elderly glioma patients,and can serve as evaluation indicators for postoperative progression in the patients.
