Purpose: Due to the preservation of the entire stomach after endoscopic resection, the occurrence of metachronous gastric cancer (MGC) remains a possibility. In this study, we investigated the incidence and risk factors for MGC in patients with early gastric cancer who underwent endoscopic submucosal dissection (ESD) and successfully eradicatedHelicobacter pylori. Materials and Methods: A retrospective analysis was conducted of 1,191 patients who underwent ESD and successfully eradicated H. pylori at the Affiliated Drum Tower Hospital of Nanjing University. Endoscopic surveillance was performed at 3, 6, and 12 months post-resection, and annually thereafter. MGC was defined as the development of a new cancer at a site other than the primary gastric cancer site, at least 1 year after the initial endoscopic resection. Results: A total of 77 patients were diagnosed with MGC during a median follow-up of 41.5 months. Kaplan-Meier analysis showed a 5-year cumulative incidence of MGC of 9.4% after successful H. pylori eradication. Multivariate analysis of the training set using Cox proportional hazards models identified male sex, severe atrophic gastritis, multiple gastric cancers before H. pylori eradication, and smoking history as independent risk factors for MGC.The nomogram exhibited favorable discrimination, with area under the curves of 0.767 and 0.822 in the training set and 0.724 and 0.745 in the testing set at 3 and 5 years, respectively. Conclusions Patients with gastric cancer who undergo endoscopic resection, even after successful H. pylori eradication, should undergo annual and continuous endoscopic surveillance for MGC.

By analyzing the connotation of "kenang （窠囊）" and its relationship with adenoid hypertrophy （AH） in children， this paper suggests that kenang plays a significant role in the development process of pediatric AH， from the initial accumulation of phlegm-dampness in the early stage， to the binding of phlegm and stasis in the middle stage， and finally the healthy qi deficiency with phlegm stagnation in the late stage， and may also serve as a key entry point for the diagnosis and treatment. From the perspective of "kenang"， and in combination with the core pathogenesis of pediatric AH characterized by lung heat and phlegm stasis， this paper proposes that the key therapeutic principles include clearing heat to resolve phlegm， activating blood to remove stasis， and reducing swelling to dissipate nodules. A staged treatment strategy based on the self-formulated Bizhi Formula （鼻窒方） with modifications is used. In the early stage of the disease， the treatment should be soothing the wind and relieving the exterior， resolving phlegm and dredging the orifices to prevent the initial knot of kenang， for which Bizhi Formula and Cangerzi Powder （苍耳子散） with modifications can be used. In the middle stage， the treatment should be dissolving phlegm and expelling stasis， dispersing knots and unblocking orifices to break down the establishment of kenang， and Bizhi Formula combined with Haizao Yuhu Decoction （海藻玉壶汤） with modifications is suggested. In the late stage， the treatment emphasizes reinforcing healthy qi and consolidating the root， resolving phlegm and dredging collaterals in order to prevent recurrence of kenang， and the suggested prescription is modified Bizhi Formula combined with Shenling Baizhu Powder （参苓白术散）.

ObjectiveTo observe the clinical efficacy of Anzi Tiaochong decoction combined with aspirin and the effects of this therapy on the peripheral blood phospholipid antibody titers， coagulation function， and CD19⁺CD24^hiCD27⁺regulatory B （Breg） cells in patients with obstetric antiphospholipid syndrome （OAPS） （pattern of kidney deficiency and blood stasis）. MethodsPatients who meet the inclusion criteria were randomly allocated into an observation group （50 patients， with 4 patients dropped out and 46 patients completed） and a control group （50 patients， with 2 patients dropped out， 1 patient excluded， and 47 patients completed） through a random number table method. The control group was treated with aspirin enteric-coated tablets， 75 mg/time， once a day， and the observation group with Anzi Tiaochong decoction， 1 bag/day on the basis of the therapy in the control group. The treatment course for both groups was 8 weeks， and the patients were followed up for 4 weeks. The traditional Chinese medicine （TCM） symptom scores， titers of peripheral blood phospholipid antibodies ［anti-cardiolipin antibody IgM （ACA IgM）， anti-cardiolipin antibody IgG （ACA IgG）， anti-β₂-glycoprotein 1 antibody IgM （β₂GP1-IgM）， and anti-β₂-glycoprotein 1 antibody IgG （β₂GP1-IgG）］， D-dimer （D-D）， thromboelastography parameters ［clotting factor activity （R）， platelet function maximum amplitude （MA）， coagulation composite index （CI）， and clot strength （G）］， CD19⁺CD24^hiCD27⁺ Breg expression rate， and adverse drug reactions were recorded for the two groups before and after treatment. ResultsAfter treatment， both groups showed decreased ACA IgM， ACA IgG， β₂GP1-IgM， β₂GP1-IgG， D-D， MA， and G （P<0.05） and increased R （P<0.05）. There was no statistically significant difference in CI. Compared with the control group， the observation group showed more significant decreases in TCM symptom scores and phospholipid antibody titers （P<0.05）. After treatment， the expression rate of Breg in the observation group was higher than that before treatment （P<0.05）.There was no significant difference in Breg expression rate before and after treatment in the control group. Neither group experienced significant adverse reactions. ConclusionAnzi Tiaochong decoction combined with aspirin can alleviate the symptoms， reduce the phospholipid antibody titers， and restore the coagulation status of patients with obstetric antiphospholipid syndrome （pattern kidney deficiency and blood stasis）. It may exert the therapeutic effects by regulating Breg to maintain the patient's immune balance.

Currently, transcatheter intervention is the preferred treatment for patients with anatomically suitable atrial septal defects. However, the use of nickel-titanium alloy occluders in interventional procedures results in lifelong presence of the implant in the body, leading to complications such as metal allergies and arrhythmias in some patients. To overcome the short-term and long-term complications associated with the presence of metal, and to avoid radiation exposure and metal toxicity, this paper reports a case of successful transcatheter closure of atrial septal defect in a pediatric patient with metal allergies using fully biodegradable occluder under ultrasound guidance, achieving excellent results by interventional therapy.

Objective:To develop an artificial intelligence (AI)-based automatic scoring model for magnetic resonance imaging-detected extramural vascular invasion (AI-mrEMVI) and evaluate its performance and prognostic value in patients with rectal cancer.Methods:In this multicenter retrospective cohort study, a total of 2 501 rectal cancer patients from seven centers between November 2012 and December 2020 were included and divided into completely independent training ( n=1 830) and validation ( n=671) cohorts. A nnUNet-based AI-mrEMVI scoring model was constructed. Manual mrEMVI scores assigned by two radiologists served as the reference standard for accessing the accuracy of the AI-mrEMVI scoring. Kaplan-Meier survival analysis and Cox regression were used to evaluate the prognostic stratification ability of the AI-mrEMVI scores. The concordance index (C-index) was calculated to evaluate prognostic performance. Results:In the validation cohort, the manual mrEMVI scores were 0-2 in 425 patients (63.3%), 3 in 89 (13.4%), and 4 in 157 (23.4%). The AI-mrEMVI model identified 0-2 in 375 patients (55.9%), 3 in 95 (14.2%), and 4 in 201 (30.0%), with an overall accuracy of 81.1% (544/671, 95% CI 77.9%-84.0%). The 3-year disease-free survival (DFS) rates for patients with AI-mrEMVI scores of 0-2, 3, and 4 were 85.2%, 70.0%, and 58.2%, respectively, and the 5-year overall survival (OS) rates were 87.2%, 81.6%, and 62.6%, respectively (DFS: χ2=48.74, P<0.001; OS: χ2=30.04, P<0.001). Multivariable Cox regression showed that for DFS, AI-mrEMVI scores of 3 and 4 were associated with hazard ratios ( HR) of 1.75 (95% CI 1.11-2.77, P=0.016) and 2.65 (95% CI 1.86-3.78, P<0.001), respectively. For OS, an AI-mrEMVI score of 4 was associated with an HR of 2.56 (95% CI 1.62-4.03, P<0.001). The C-index values of the AI-mrEMVI scoring model for predicting DFS and OS were 0.647 (95% CI 0.608-0.686) and 0.650 (95% CI 0.598-0.702), respectively. Conclusion:The proposed AI-mrEMVI automatic scoring model demonstrated high diagnostic accuracy and performed favorably in predicting DFS and OS prognostic risk in patients with rectal cancer.

Objective To study the changes of lipid peroxidation and antioxidant capacity in patients with hypercholesterolemia.Methods A total of 100 patients with elevated cholesterol treated in the People's Hospital of Qitaihe from January to May 2024 were included in hypercholesterolemia group,and another 80 people with normal blood lipid in the hospital during the same period were included in control group.Malondialdehyde(MDA),glutathione(GSH),glutathione reductase(GR)and total antioxidant capacity(TAC)were determined in all subjects.Results The levels of total cholesterol,low density lipoprotein-cholesterol and MDA in hypercholesterolemia group were significantly higher than those in control group,while the levels of GSH,GR and TAC were significantly lower than those in control group(P＜0.05).Conclusion Patients with hypercholesterolemia have severe lipid peroxidation,which may cause vascular endothelial cell damage.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To perform routine plasma test, SARS-CoV-2 nucleic acid test, and respiratory pathogenic microorganism nucleic acid test on plasma samples collected from 1 040 healthy plasma donors in winter.Methods:Plasma samples were collected from 1 040 healthy plasma donors at Yunmeng Plasma Collection Station in the winter of 2020. Routine plasma test, HBV/HCV/HIV nucleic acid test, SARS-CoV-2 nucleic acid test, and 22 respiratory pathogenic microorganism nucleic acid test were performed to analyze the quality of blood plasmas.Results:All plasma samples were qualified in the routine tests, meeting the requirements of the Chinese Pharmacopoeia, and tested negative for SARS-CoV-2 nucleic acid. Respiratory pathogenic microorganism nucleic acids were detected in 29 samples with a positive rate of 2.79% (29/1 040). There were 21 cases of simple virus infections, including 17 cases of coronavirus subtype infection, three cases of parainfluenza virus type 2 infection, and one case of human bocavirus infection. Eight cases were mixed infections of viruses and bacteria, four of which were viral infection combined with Bordetella pertussis. The 29 positive samples were collected from people of different age groups, including two from 31-40 years old (1.96%, 2/102 ), three from 41-50 years old (1.59%, 3/189), five from 51-55 years old (1.94%, 5/257), and 19 from 56-60 years old (4.59%, 19/414). Samples from the people aged 56-60 years accounted for the most (39.81%, 414/1 040), as well as the infection rate in this age group. Conclusions:In autumn and winter, respiratory pathogenic microorganism nucleic acid test should be performed when collecting plasma samples from donors aged 56-60 years in addition to meeting the requirements of the Chinese Pharmacopoeia. It is also suggested to conduct respiratory pathogenic microorganism nucleic acid test on pooled plasma and blood products.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
