To address issues such as loss of detailed information, blurred target boundaries, and unclear structural hierarchy in medical image fusion, this paper proposes an adaptive feature medical image fusion network based on a full-scale diffusion model. First, a region-level feature map is generated using a kernel-based saliency map to enhance local features and boundary details. Then, a full-scale diffusion feature extraction network is employed for global feature extraction, alongside a multi-scale denoising U-shaped network designed to fully capture cross-layer information. A multi-scale feature integration module is introduced to reinforce texture details and structural information extracted by the encoder. Finally, an adaptive fusion scheme is applied to progressively fuse region-level features, global features, and source images layer by layer, enhancing the preservation of detail information. To validate the effectiveness of the proposed method, this paper validates the proposed model on the publicly available Harvard dataset and an abdominal dataset. By comparing with nine other representative image fusion methods, the proposed approach achieved improvements across seven evaluation metrics. The results demonstrate that the proposed method effectively extracts both global and local features of medical images, enhances texture details and target boundary clarity, and generates fusion image with high contrast and rich information, providing more reliable support for subsequent clinical diagnosis.

Hemoglobin A1c (HbA1c) has a unique structure that makes monoclonal antibody (mAb) preparation challenging. This study aims to develop a method for preparing HbA1c mAbs and establish a fluorescent immunochromatographic assay (FICA) for rapid detection of HbA1c. Three glycosylated peptides were synthesized and used to prepare complete antigens, which were identified by dot enzyme-linked immunosorbent assay (Dot-ELISA) and ultraviolet absorption spectroscopy. The complete antigens and natural HbA1c were used for cross-immunization of mice, and the optimal complete antigen was selected. The mouse with the highest serum titer was chosen for mAb preparation. The purity and specificity of the mAbs were verified, and a FICA method was developed. The optimal complete antigen, with a titer of 1:512 000, was successfully prepared and selected. Fusion with splenocytes resulted in four specific HbA1c antibodies (purity > 90%). The best antibody exhibited a binding constant (Ka) of 1.67×1010 L/mol with the antigen. Based on this antibody, a FICA method was successfully established, capable of producing results within 15 min. The method demonstrated a good linear range (3%-13% HbA1c, y=0.071 3x+0.005 6, R2=0.993 7), recovery rates of 98%-102%, precision < 10.00%, and no nonspecific reactions. Clinical testing of 210 samples showed positive agreement of 96.36%, negative agreement of 97.00%, and overall agreement of 96.68%. The receiver operating characteristic (ROC) curve analysis yielded an area under curve (AUC) of 0.980 9 [95% confidence interval (CI): 0.961 0-1.000 0], with high consistency verified in multicenter studies. We successfully developed a key technique for preparing HbA1c monoclonal antibodies and established a FICA method for rapid detection of HbA1c. It will provide an efficient and convenient detection method for the early diagnosis and long-term management of diabetes and its complications.

A 65-year-old male patient was admitted for recurrent lymph node enlargement for 5 years and elevated creatinine for 6 months. This patient was diagnosed with angioimmunoblastic T-cell lymphoma 5 years ago and underwent multiple lines of anti-tumor therapy, including cytotoxic chemotherapy; epigenetic modifying drugs such as chidamide and azacitidine; the immunomodulator lenalidomide; and targeted therapy such as rituximab, a CD20-targeting antibody, and brentuximab vedotin, which targets CD30. Although the tumor was considered stable, multiple virus activation (including BK virus, JC virus, and cytomegalovirus) accompanied by the corresponding organ damage (polyomavirus nephropathy, cytomegalovirus retinitis, and progressive multifocal leukoencephalopathy) occurred during anti-tumor treatment. Anti-tumor therapy was suspended and ganciclovir was used. The serum viral load decreased and organ functions were stabilized. The purpose of this report was to raise clinicians′ awareness of opportunistic virus reactivation during anti-tumor treatment.

Objective:To compare the short-term efficacy of laparoscopic sleeve gastrectomy (LSG) combined with sharp His angle reconstruction (LSG-His) versus traditional LSG.Methods:In this retrospective cohort study we collected clinical data of patients with obesity who had undergone LSG or LSG-His in the Department of General Surgery, Beijing Chaoyang Hospital, Capital Medical University, from January to June 2022. After excluding patients with incomplete follow-up data and those with hiatal hernia, 83 obese patients, of which 39 who had undergone LSG (LSG group) and 44 who had undergone LSG-His (LSG-His group), were included in the study. The basic steps in LSG-His are the same as in conventional LSG. After continuous suturing of the gastric staple line, one stitch is placed between the proximal side of the gastric greater curvature staple line and the proximal side of the gastric fundus posterior wall with the left diaphragm, and another stitch between the right side of the gastric fundus and the esophagus, reconstructing the sharp His angle. Clinical data, postoperative complications, and follow-up data on weight loss and gastroesophageal reflux disease (GERD) symptoms 1-, 3-, 6-, and 12-months post-discharge were compared between the two groups. GERD symptoms were assessed using the Gastroesophageal Reflux Disease Questionnaire and Reflux Diagnostic Questionnaire.Results:There were no significant differences between the two groups in baseline characteristics, length of hospital stay, hospitalization costs, intraoperative bleeding, postoperative nausea and vomiting, dysphagia, or postoperative complications (all P>0.05). Compared with the LSG group, the LSG-His group had significantly longer operative times (92 [80, 100] minutes vs. 80 [70, 100] minutes, U=2.227, P=0.026), higher postoperative 24-hour pain scores (5.2±1.8 vs. 4.3±1.9, t=-2.065, P=0.041), and higher rates of morphine use (70.5% [31/44] vs. 46.2% [18/39], χ2=4.519, P=0.025). The incidence of new-onset GERD 12 months postoperatively was significantly lower in the LSG-His than the LSG group (10.7% [3/28] vs. 61.3% [19/31], χ2=14.00, P<0.001). According to changes in Gastroesophageal Reflux Disease Questionnaire and Reflux Diagnostic Questionnaire scores, the LSG-His group also had significantly lower rates of exacerbation of GERD (2/16 vs. 5/8, χ2=4.27, P=0.021) and higher rates of GERD remission (12/16 vs. 2/8, χ2=3.62, P=0.032) than did the LSG group. Additionally, excess weight loss rates were significantly higher in the LSG-His group at 3 months [(54.7± 18.7)% vs. (46.5±15.0)% , t=-2.166, P=0.033], 6 months [(73.8±24.7)% vs. (64.0±19.1)% , t=-2.018, P=0.047], and 12 months [(82.9±26.7)% vs. (72.2±19.3)%, t=-2.063, P=0.042] than in the LSG group. Conclusion:Compared with LSG, LSG-His is safe and feasible and achieves better short-term control of postoperative GERD and more effective weight loss. Further large-scale, long-term, prospective studies are needed to confirm the long-term efficacy of LSG-His.
