Objective:To review and summarize the experience of robot-assisted laparoscopic trans-plant nephrectomy,share the surgical steps and technical key points,and provide a reference for clinical practice.Methods:A retrospective analysis was conducted on the perioperative data of 5 patients who underwent robot-assisted laparoscopic donor nephrectomy at Peking University Third Hospital from August 2023 to December 2024.The surgical steps and key points were summarized.The continuous variables were described by medians(ranges).Results:A total of 5 patients were included in the analysis,of whom 2 were male and 3 were female.The median age of the patients was 37(31-68)years.The me-dian time from kidney transplantation to donor nephrectomy was 10(3-22)years.The indications for donor nephrectomy included recurrent hematuria,abdominal pain,malignant tumor of the transplanted kidney,and recurrent infection with hydronephrosis of the transplanted kidney.The excised transplanted kidneys from all the 5 patients had a single renal artery and a single renal vein.The median operation time was 212(145-351)min,the median blood loss was 300(20-500)mL,and the median post-operative hospital stay was 7(4-25)days.Only 1 patient experienced intraoperative complications,who experienced an external iliac artery injury during the operation and underwent suture repair.No pa-tient died during the perioperative period.Postoperative pathological results showed that 3 patients had end-stage non-functional kidneys,1 patient had BK virus-associated urothelial carcinoma,and 1 patient had chronic pyelonephritis with renal parenchymal atrophy.Conclusion:Robot-assisted laparoscopic transplant nephrectomy as a new surgical approach is feasible and safe.Compared with traditional open transplant nephrectomy,its advantage lies in the ability to directly observe and prioritize the management of the renal pedicle of the transplanted kidney,while completely freeing and removing the transplanted kidney outside the renal capsule.With the continuous accumulation of experience,this surgical technique is expected to become a powerful alternative to traditional open transplant nephrectomy.

To provide in-service medical technicians and nurses with convenient access to continuing education resources in transfusion medicine, reduce transfusion-related adverse events, and ensure the safety, rationalization, and effectiveness of clinical transfusion, we designed and developed an online transfusion continuing education platform. The platform was based on the new managed code programming model.NET Core and the powerful functions of hypertext preprocessor PHP 7.4, addressing current issues in transfusion online continuing education. Through in-depth analysis of student attributes, learning behaviors, and teaching behaviors, a comprehensive online continuous teaching quality evaluation index system was established. This system not only facilitates the quantitative assessment of teaching quality but also successfully integrates the two core functions of teaching and management, thereby achieving unified online teaching.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Acute lung injury (ALI), as a common clinical emergency, is pulmonary edema and diffuse lung infiltration caused by inflammation. The lack of non-invasive alert strategy, resulting in failure to carry out preventive treatment, means high mortality and poor prognosis. Stimulator of interferon genes (STING) is a key molecular biomarker of innate immunity in response to inflammation, but there is still a lack of STING-targeted strategy. In this study, a novel STING-targeted PET tracer, [¹⁸F]FBTA, was labeled with high radiochemical yield (79.7 ± 4.3%) and molar activity (32.5 ± 2.9 GBq/μmol). We confirmed that [¹⁸F]FBTA has a strong STING binding affinity (K_d = 26.86 ± 6.79 nmol/L) and can be used for PET imaging in ALI mice to alert early lung inflammation and to assess the efficacy of drug therapy. Our STING-targeted strategy also reveals that [¹⁸F]FBTA can trace ALI before reaching the computed tomography (CT) diagnostic criteria, and demonstrates its better specificity and distribution than [¹⁸F]fluorodeoxyglucose ([¹⁸F]FDG).

Sepsis-induced liver injury (SILI) is an important cause of septicemia deaths. BaWeiBaiDuSan (BWBDS) was extracted from a formula of Panax ginseng C. A. Meyer, Lilium brownie F. E. Brown ex Miellez var. viridulum Baker, Polygonatum sibiricum Delar. ex Redoute, Lonicera japonica Thunb., Hippophae rhamnoides Linn., Amygdalus Communis Vas, Platycodon grandiflorus (Jacq.) A. DC., and Cortex Phelloderdri. Herein, we investigated whether the BWBDS treatment could reverse SILI by the mechanism of modulating gut microbiota. BWBDS protected mice against SILI, which was associated with promoting macrophage anti-inflammatory activity and enhancing intestinal integrity. BWBDS selectively promoted the growth of Lactobacillus johnsonii (L. johnsonii) in cecal ligation and puncture treated mice. Fecal microbiota transplantation treatment indicated that gut bacteria correlated with sepsis and was required for BWBDS anti-sepsis effects. Notably, L. johnsonii significantly reduced SILI by promoting macrophage anti-inflammatory activity, increasing interleukin-10⁺ M2 macrophage production and enhancing intestinal integrity. Furthermore, heat inactivation L. johnsonii (HI-L. johnsonii) treatment promoted macrophage anti-inflammatory activity and alleviated SILI. Our findings revealed BWBDS and gut microbiota L. johnsonii as novel prebiotic and probiotic that may be used to treat SILI. The potential underlying mechanism was at least in part, via L. johnsonii-dependent immune regulation and interleukin-10⁺ M2 macrophage production.

Objective To investigate the potential role of CXC chemokine ligand 16 (CXCL16)/CXC chemokine receptor 6 (CXCR6) pathway in the progression of diabetic nephropathy (DN). Methods 8?week old male db/db mice were randomly divided into DN group and DN inflamed group. 10% casein was subcutaneously injected to induce the DN mouse model with inflammation. In vitro, HK?2 cells were treated with high glucose (HG), and IL?1β+HG to investigate the effect of inflammatory stress on HK?2 cells. Further knockdown CXCL16 was mediated by RNA interference to determine the effects of CXCl16, then cells were divided into HG+IL?1βgroup, HG+IL?1β + siCXCL16 group and HG + IL?1β + vehicle group. Changes of renal function in mice were assessed by 24 h proteinuria and N?acetyl?β?D?glucosaminidase (NAG) during 8 weeks. The ultra?microstructure was checked by electron microscopy at 8th week. Lipid accumulation in kidneys and HK?2 were observed by Filipin staining and quantitative assay of intracellular free cholesterol. The protein expressions of CXCl16, CXCR6, a disintegrin and metalloproteinase?10 (ADAM10), fibronectin and α smooth muscle actin (α?SMA) in renal tissue were detected by immunohistochemistry and Western blotting. The mRNA and protein expressions of CXCl16, CXCR6, ADAM10, fibronectin andα?SMA in HK?2 cells were detected by real?time PCR and Western blotting, and protein expressions of CXCl16, CXCR6 and ADAM10 in HK?2 cells were also tested by cell immunofluorescence. Results Mice in DN inflamed group had higher 24 h proteinuria and NAG than those in DN group, and the differences between two groups shown statistical significance at 8th week (all P<0.05). Compared with DN mice, DN inflamed mice had more vacuoles within renal tubular cells, with mitochondrial swelling, deformation and decrease. Lipid accumulation and protein expressions of fibronectin and α?SMA were increased in DN inflamed group when compared with DN group (all P<0.05). Further, the expressions of CXCL16, CXCR6, ADAM10 were significantly increased in DN inflamed group (all P<0.05). In vitro, the mRNA and protein expressions of CXCL16, CXCR6, ADAM10, fibronectin and α?SMA, and lipid accumulation were increased in high glucose plus IL?1βgroup when compared with high glucose group (all P<0.05). However, after siRNA of CXCL16 transfection, the mRNA and protein expressions of CXCL16, CXCR6, ADAM10, fibronectin andα?SMA were down?regulated in HG+IL?1β+siCXCL16 group as compared with high glucose+IL?1βgroup (all P<0.05). Furthermore, lipid accumulation was decreased (P<0.05). Conclusion Inflammation accelerates tubulointerstitial injury in DN partly through the activation of CXCL16 pathway, which may facilitate the lipid accumulation in tubular epithelial cells.
