Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

Background and Aims:Totally implantable venous access port(TIVAP)are widely used for chemotherapy,blood transfusion,and nutritional support in patients with malignancies.Among them,upper arm port(UAP)are increasingly recommended in clinical practice due to their advantages in avoiding thoracic complications and providing more concealed incisions.Currently,two main implantation techniques are used for UAP:the tunnel needle-transverse incision technique and the puncture point-transverse incision technique.This study aims to compare the clinical outcomes of these two techniques in patients with hematological malignancies,focusing on safety and cosmetic appearance,to provide evidence for clinical decision-making.Methods:A retrospective analysis was conducted on 412 patients with hematological malignancies who underwent UAP implantation at Xiangya Hospital of Central South University between December 2021 and December 2024.Based on the implantation method,patients were divided into the tunnel needle-transverse incision group(n=200)and the puncture point-transverse incision group(n=212).Intraoperative variables(operative time,intraoperative pain score,catheter kinking at the pocket,intraoperative blood loss)and postoperative indicators(incidence of complications and incision aesthetic satisfaction)were compared between the two groups.Results:There were no significant differences in baseline characteristics between the two groups(all P>0.05),indicating comparability.The puncture point-transverse incision group showed superior performance in operative time[(32.99±4.91)min vs.(41.42±5.35)min],catheter kinking rate(1.4％vs.8.5％),and incision aesthetic satisfaction(7.99±0.58 vs.6.26±0.86)compared with the tunnel needle-transverse incision group(all P<0.05).Although the puncture point group had slightly more intraoperative bleeding[(4.52±1.02)mL vs.(4.16±0.83)mL],the difference,while statistically significant,was of limited clinical relevance.No significant differences were observed between the two groups in intraoperative pain scores or incidence of postoperative complications(both P>0.05).Conclusion:The puncture point-transverse incision technique offers significant advantages in terms of operative efficiency,reduced catheter kinking,and improved incision aesthetics,without compromising safety.It represents a promising alternative to the traditional tunnel needle-transverse incision method and has strong potential for broader clinical adoption.The puncture point-transverse incision technique offers advantages such as shorter operative time,lower catheter kinking rate,and higher incision aesthetic satisfaction.It is a promising alternative to the traditional tunnel needle-transverse incision technique and has good potential for clinical application and promotion.

Background and Aims:Totally implantable venous access ports(TIVAP)are widely used in patients requiring long-term intravenous therapy.Traditional butterfly needle puncture fixation methods have limitations,including low success rates,increased pain,and risk of needle-stick injury.This study aimed to design an adjustable puncture protection kit for butterfly needles and evaluate its clinical utility using a simulated device.Methods:A prospective randomized controlled trial was conducted with 70 patients implanted with upper arm ports in the Hematology Department of Xiangya Hospital,Central South University,from January to December 2024.The patients were divided into a study group and a control group,with 35 cases in each,using a randomized block design.The study group underwent puncture with the simulated adjustable protection kit,while the control group used the traditional finger fixation method.Outcomes compared included first-attempt success rate,vertical puncture rate,pain score,puncture time,and complication rate.Results:The baseline characteristics of the two groups were balanced.The study group had significantly higher first-attempt puncture success rate and vertical puncture rate than the control group(94.3%vs.77.1%;91.4%vs.57.1%,both P<0.05).In the experimental group compared with the control group,pain scores were lower(1.80±1.13 vs.2.94±1.33,P<0.05),and puncture time was shorter[(31.31±9.05)s vs.(41.80±23.97)s,P<0.05].There was no significant difference in the incidence of puncture-related complications between the two groups(2.9%vs.14.3%,P>0.05).Conclusion:The simulated adjustable butterfly needle puncture protection kit effectively improves puncture success,enhances efficiency,reduces patient pain,and demonstrates good clinical safety.This innovative design provides a promising solution for reducing needle-stick injury risks and optimizing port puncture procedures,although larger,multicenter,and long-term studies are warranted.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective To explore the feasibility and safety of non-anticoagulation veno-venous extracorporeal membrane oxygenation(VV-ECMO)in patients with severe chest trauma.Methods A retrospective cohort study method was used.A total of 19 patients with severe chest trauma who received VV-ECMO with a delayed anticoagulation strategy at Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2018 to October 2021 were included in the delayed anticoagulation group,and 20 patients with severe chest trauma who received VV-ECMO with a non-anticoagulation strategy from November 2021 to October 2024 were included in the non-anticoagulation group.The overall clinical characteristics of the patients were statistically analyzed,including gender,age,injury severity score(ISS),acute physiology and chronic health evaluationⅡ(APACHEⅡ),reason for VV-ECMO,use of vasoactive drugs,oxygenation index(PaO2/FiO2),and interval from injury to VV-ECMO.The primary outcomes were hemorrhagic and thrombotic complications.The secondary outcomes were blood transfusion during VV-ECMO,VV-ECMO time,mechanical ventilation time,intensive care unit(ICU)length of stay,and 28-day mortality.Results There was no significant difference in gender,age,ISS score,APACHEⅡscore,reason for VV-ECMO,use of vasoactive drugs,PaO2/FiO2,and interval from injury to VV-ECMO between the non-anticoagulation group and the delayed anticoagulation group.There was no significant difference in overall incidence of hemorrhagic and thrombotic between the two groups[incidence of hemorrhagic complications:15.0%(3/20)vs.31.6%(6/19),incidence of thrombotic:15.0%(3/20)vs.5.3%(1/19),both P>0.05].The infusion rate of 4 or more paked red blood cell(PRBC)within 24 hours during VV-ECMO in the non-anticoagulation group was significantly lower than that in the delayed anticoagulation group[5.0%(1/20)vs.31.6%(6/19),P<0.05].The amount of PRBC and platelet transfusion and the time on VV-ECMO in the non-anticoagulation group during VV-ECMO were significantly lower than those in the delayed anticoagulation group[PRBC(U):5.8±3.8 vs.8.1±3.1,platelets(U):1(0,1)vs.2(1,3),time on VV-ECMO(hours):71.55±24.37 vs.114.21±34.08,all P<0.05].There were no statistically significant differences in the amount of plasma and cryoprecipitate transfusion during VV-ECMO,mechanical ventilation time,ICU hospitalization time,and 28-day mortality between the two groups.Conclusion For patients with severe chest trauma receiving VV-ECMO withholding routine systemic anticoagulation did not result in thrombotic complications or higher mortality and required less PRBC and platelet transfusions.Non-anticoagulant VV-ECMO is safe and feasible for patients with severe chest trauma with high risk of bleeding.

Objective:Explore the protective effect and mechanism of methyl badosolone (CDDO-Me) on rats with traumatic brain injury (TBI).Methods:A total of 72 SPF-grade SD rats aged 8 weeks were randomly (random number) divided into 4 groups ( n=18) using the random number table method: Sham, TBI, TBI+Vehicle, and TBI+CDDO-Me. The rat TBI model was established using the hydraulic impact head injury method. The TBI+CDDO-Me group was administered CDDO-Me (dissolved in 1% DMSO, at a dose of 10 mg/kg) via intraperitoneal injection 30 minutes after modeling, twice a day for a total of 3 days. On the third day after modeling, brain tissue was collected for pathological and water content detection after mNSS scoring. Immunofluorescence double staining was used to detect the expression of nuclear factor erythroid2 related factor 2 (Nrf2); immunohistochemical staining was used to detect the expression of ionized calcium binding adapter molecule-1(Iba-1); ELISA was used to detect the levels of tumor necrosis factor-α(TNF-α), interleukin (IL)-1β, and IL-18 in serum; kits were used to detect the levels of malondialdehyde (MDA) and reactive oxygen species (ROS); Western blot was used to detect the expression of the Nrf2 pathway, B-cell lymphoma-2 (BCL-2), and BCL-2 associated X protein (BAX). Results:(1) Compared with the Sham group, the mNSS scores and water content in the injured cortex of the TBI group rats were significantly increased (both P<0.05), and both significantly decreased after CDDO-Me intervention (both P<0.05). (2) Compared with the Sham group, the proportion of Nissl-stained injured neurons and apoptotic positive cells in the TBI group rats were significantly increased (both P<0.05), and both significantly decreased after CDDO-Me intervention (both P<0.05), accompanied by a decrease in BAX protein expression and upregulation of BCL-2 protein expression (both P<0.05). (3) Immunofluorescence and Western blot results showed that compared with the Sham group, the expression of total Nrf2, nuclear Nrf2, HO-1, and NQO1 proteins in the TBI group were all increased (all P<0.05), and the increase was more significant after CDDO-Me intervention (all P<0.05). (4) Immunohistochemistry and ELISA results showed that compared with the Sham group, the levels of MDA, ROS, Iba-1 in brain tissue and the levels of TNF-α, IL-1β, and IL-18 in serum in the TBI group rats were all significantly increased (all P<0.05), and all significantly decreased after CDDO-Me intervention (all P<0.05). Conclusion:CDDO-Me helps to reduce oxidative stress and inflammatory responses in TBI rats, and the mechanism may be related to the activation of the Nrf2/HO-1 antioxidant stress pathway.
