Objective To investigate the safety and efficacy of hepatic arterial infusion chemotherapy(HAIC)using lenvatinib plus immune checkpoint inhibitors(ICI)in the treatment of progressive advanced hepatocellular carcinoma(HCC).Methods The clinical data of 67 patients with HCC of BCLC stage C,who received HAIC treatment at the Guangdong Provincial Hospital of Traditional Chinese Medicine of China from May 2018 to March 2022 and were assessed as in disease progression(PD)status after HAIC treatment,then had to further receive second-line treatment with lenvatinib plus ICI regimen.According to modified Response Evaluation Criteria in Solid Tumors(mRECIST),the tumor responses,including overall survival(OS),progression free survival(PFS),objective response rate(ORR),and disease control rate(DCR),were evaluated.Univariate analysis and multivariate analysis based on the COX proportional hazards regression model were used to determine the prognosis-related risk factors.According to the Common Terminology Criteria for Adverse Events version 5.0(CTCAE 5.0),the treatment-related adverse effects were recorded and evaluated.Results The median OS and median PFS in the 67 patients with HCC of BCLC stage C receiving second-line treatment with lenvatinib plus ICI regimen,who were evaluated as in PD status after first-line HAIC treatment,were 18.4 months and 7.2 months respectively.The ORR and DCR were 22.4％(15/67)and 67.4％(45/67)respectively.Univariate analysis and multivariate analysis showed that Eastern Cooperative oncology Group(ECOG)score and hepatitis B virus(HBV)infection were the independent risk factors affecting OS,while AFP level was an independent risk factor affecting PFS.The main treatment-related adverse reactions included elevation of transaminase level,hypertension,and hyperbilirubinemia.No death occurred during the therapeutic course.Conclusion For patients with HCC of BCLC stage C,who become in PD status after first-line HAIC treatment,second-line treatment with lenvatinib plus ICI regimen carries satisfactory efficacy and its adverse reaction is tolerable.

The mortality rates are significantly elevated with the rapid progression of acute liver failure in the absence of timely diagnosis and treatment. Liver transplantation is an effective therapeutic approach that can halt disease progression, but transplantation timing is a crucial factor affecting prognosis. Patients with acute liver failure should be promptly transferred to hospitals equipped for liver transplantation while simultaneously preparing for the procedure during the course of treatment to avoid missing the opportunity to save lives when the condition suddenly worsens. Auxiliary liver transplantation preserves the patient's native liver while transplanting a new liver. Therefore, patients are expected to gradually reduce immunosuppressants following the regeneration of the autologous liver, so avoiding the problem of lifelong use of immunosuppressants. This is also a unique advantage, offering benefits to patients undergoing auxiliary liver transplantation therapy for acute liver failure, while simultaneously presenting challenges for clinicians in terms of technical skill and comprehensive management.

Objective:To evaluate the safety and efficacy of using small and ultra-small sized grafts for in situ auxiliary liver transplantation in the treatment of portal hypertension.Methods:A prospective single-arm cohort study was conducted. Patients who underwent liver transplantation at Beijing Friendship Hospital from December 2014 to July 2025 were included. Intraoperative portal vein pressure was routinely monitored, with the target regulation for portal vein blood flow set at<15 mmHg (1 mmHg=0.133 kPa) and follow-up continued until September 2025. The primary endpoints were the patient's status and graft survival. The secondary endpoints were small-for-size syndrome and perioperative complications. The small-for-size syndrome was graded according to the 2023 International Liver Transplantation Society consensus statement.Results:A total of 33 cases were enrolled. Among them, 22 had ultra-small size grafts, 11 had small-size grafts, 28 had living donor grafts, and five had split grafts. The graft-to-recipient weight ratio in living donor liver transplantation was 0.31%～0.79%, while in split liver transplantation it was 0.45%～1.02%. Intraoperative portal vein pressure of ≥15 mmHg was observed in 11 cases, who underwent portal vein blood flow adjustment via splenic artery ligation (2 cases), partial splenectomy (8 cases), and/or restrictive portocaval shunting (1 case), after which all patients achieved the target portal vein pressure. All cases completed at least one month of follow-up, with 28 cases following for more than one year, and the median follow-up period was 36.5 months. Early-stage postoperative small-for-size syndrome occurred in eight cases (24.2%, 8/33), all classified as grade A, with improvements following supportive treatment. Severe complications (Clavien-Dindo≥Ⅲ) occurred in three cases (9.1%, 3/33). The one-year survival rate was 92.9% (26/28). The overall survival rate at the end of follow-up was 90.9% (30/33). No patients experienced graft loss or death due to small-for-size syndrome. Graft tissue tested negative for hepatitis B core antibody and covalently closed circular DNA, and hepatitis B surface antigen seroconversion was achieved following second-stage residual liver resection and under a combined strategy of potent nucleos(t)ide analogs and hepatitis B immunoglobulin in ten cases of hepatitis B-related disease.Conclusions:With standardized portal vein blood flow monitoring and individualized portal vein blood flow adjustment, in situ auxiliary liver transplantation can safely and effectively use small and even ultra-small sized grafts, thereby significantly expanding graft sources and ensuring donor and recipient safety. These findings warrant further validation and promotion in multicenter controlled studies.

Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to an infection. It is a high-mortality syndrome that is widespread globally. In this review, we explore the evolving understanding of the immunological features of sepsis, emphasizing the simultaneous occurrence of pro-inflammatory and anti-inflammatory responses during the disease progression. Early in the disease course, the host is typically in a pro-inflammatory state, characterized by excessive inflammatory responses and vascular damage. As the disease progresses, the host tends toward an immunosuppressive state, marked by immune suppression and secondary infections. This article outlines the immunological characteristics of these two states, including the reciprocal promotion of inflammatory storms and coagulation abnormalities, as well as the death and depletion of immune cells. The heterogeneity of sepsis presents a significant challenge to targeted therapy. A key future direction in sepsis immunology diagnosis and treatment is distinguishing endotypes among sepsis patients, identifying the immunological features and pathogenic mechanisms of each endotype, and enabling focused therapeutic interventions targeting specific sepsis endotypes.

We reported a 32 years female patient in whom lung metastasis from breast cancer was presented as solitary pulmonary pure ground-glass opacity (GGO) lesion. The patient received rational preoperative examinations and surgery though the preoperative diagnosis was not accurate. Because of different therapy strategies and purposes, it is crucial to make distinction of atypical metastases from primary cancers. Thus, for patients with a history of malignancy, possible metastasis should be taken into consideration if new GGO was found on the CT. Besides this, the follow-up interval of CT should be shortened appropriately, preoperative examinations and surgical procedures should be made according to the suggestions of multidisciplinary team.

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.
