Lung transplantation is the optimal treatment for end-stage lung diseases and can significantly improve prognosis of the patients. However, postoperative complications such as infection, rejection, ischemia-reperfusion injury, and other challenges (like shortage of donor lungs) , limit the practical application of lung transplantation in clinical practice. Chinese research teams have been making continuous efforts and have achieved breakthroughs in basic research on lung transplantation by integrating emerging technologies and cutting-edge achievements from interdisciplinary fields, which has strongly propelled the development of this field. This article will comprehensively review the academic progress made by Chinese research teams in the field of lung transplantation in 2024, with a focus on the achievements of Chinese teams in basic research on lung transplantation. It aims to provide innovative ideas and strategies for key issues in the basic field of lung transplantation and to help China's lung transplantation cause reach a higher level.

Hepatocellular carcinoma(HCC)is one of the most common malignant tumors globally.Programmed death protein-1(PD-1)/programmed death protein ligand-1(PD-L1)inhibitors promote the reactivation of anti-tumor immune response by bloc-king the negative modulatory signaling pathway of T cells'activa-tion and inhibiting the immune escape pathway of tumor cells.PD-1/PD-L1 inhibitors become a novel therapeutic strategy to treat HCC.However,long-term clinical outcomes show that HCC patients treated with anti-PD-1/PD-L1 monotherapy still have high rates of recurrence and metastasis.Combination immuno-therapy is a novel therapeutic strategy to treat advanced HCC pa-tients,among which PD-1/PD-L1 inhibitors in combination with anti-vascular endothelial growth factor(VEGF)agents have showed promising efficacy and better safety.PD-1/PD-L1 inhib-itors plus anti-VEGF agents combined therapy inhibit the growth of hepatoma cells by participating in the cancer immunity cycle pathway.This review focuses on the research progress of PD-1/PD-L1 inhibitors,anti-VEGF agents and their combined therapy in the clinical treatment of HCC.

Objective:To investigate the effect of genetic polymorphism of MTHFR C677T (rs1801133) on methotrexate (MTX) related toxicity in pediatric mature B-cell lymphoma patients. Methods:Fifty-eight intermediate and high risk patients under 18 years of age with mature B-cell lymphoma who received 5 g/m2 MTX (24 h intravenous infusion) in Sun Yat-sen University Cancer Center from August 2014 to December 2021 were included,and their toxicity of high-dose MTX (HD-MTX) were monitored and analyzed. Results:Among the 58 pediatric patients,the number of CC,CT,and TT genotypes for MTHFR C677T was 33,19 and 6,respectively. A total of 101 courses of HD-MTX therapy were counted,of which plasma MTX level>0.2 μmol/L at 48 h post-MTX infusion were observed in 35 courses,≤0.2 μmol/L in 66 courses. Inter-group comparison showed that plasma MTX level>0.2 μmol/L at 48 h post-MTX infusion increased the risk of developing oral mucositis (P<0.05). Compared with wild-type (CC genotype),patients in the mutant group (CT+TT genotype) were more likely to develop myelosuppression,manifested as anemia,leucopenia,neutropenia and thrombocytopenia. However,plasma MTX level at 48 h was not associated with MTHFR C677T gene polymorphism. Conclusion:The risk of developing oral mucositis in children with mature B-cell lymphoma is associated with plasma MTX concentration. Polymorphism of MTHFR C677T gene is not related to plasma MTX concentration in children with mature B-cell lymphoma,but is related to grade Ⅲ to Ⅳ hematological toxicity.

Objective To identify the factors associated with frailty in lung transplant patients by a meta-analysis.Methods Computerized search was performed for studies on the influencing factors of frailty in lung transplant patients in the CNKI,WanFangData,VIP,CBM,PubMed,Web of Science,Embase,Elsevier ScienceDirect and CINAHL databases.The search was conducted from the time of database construction to November 2023.Literature screening,quality assessment,and data extraction were performed independently by 2 investigators,and Meta-analysis was performed using Stata 17.0 software.Results 10 cohort studies,including 1 999 patients,were finally included,and 13 influencing factors were extracted,including advanced age(OR=1.05),female(OR=2.50),BMI(OR=0.38),diagnosis of primary pulmonary disease(OR=2.90),6MWD(OR=0.34),and lung allocation score(OR=0.69),FVC(OR=0.60),pre-transplant frailty(OR=0.81),hypoproteinemia(OR=4.12),hemoglobin(OR=0.50),anemia(OR=4.37),length of ICU stay(OR=1.24),and total length of stay(OR=1.05).Short Physical Performance Battery is an assessment tool for frailty in lung transplant patients,with an incidence of frailty in 24％before transplantation and 50％in post-transplantation.Fried Frailty Phenotype is an assessment tool for frailty in lung transplant patients,with a pre-transplant frailty incidence of 30％.Conclusion There are many factors involved in the incidence of frailty in lung transplant patients,and nursing staff should dynamically evaluate the frailty of lung transplant patients,and give individualized and precise interventions in combination with a multidisciplinary model to improve or delay the progression of frailty.

Objective To evaluate the effect of remote interventions with digital health technologies in lung transplant patients.Methods Databases,including CKNI,Wangfang,VIP,CMB,Cochrane Library,PubMed,Embase,Web of Science,Scopus and BMJ Best Practice were searched from their inception to July 2023.There were 2 researchers who independently screened and extracted the literature,and then evaluated quality of the included studies.Meta-analysis was performed using RevMan 5.2.Results 10 studies with 1 262 patients were included.The results of meta-analysis showed that compared with conventional intervention,remote intervention based on digital health technology could improve self-monitoring compliance of lung transplant patients[0R=0.64,95％CI(0.46,0.88),P=0.006],improve quality of life including mental health status[OR=3.08,95％CI(0.41,5.74),P=0.020]and physical health status[OR=3.81,95％CI(1.19,6.43),P=0.004].In terms of the intervention forms,the application-based remote intervention had better self-monitoring compliance,and the difference was statistically significant(P=0.007).However,in terms of the comparison of readmission rate[OR=1.73,95％CI(0.98,3.04),P=0.060],anxiety[OR=-0.12,95％CI(-1.36,1.11),P=0.850],and depression[OR=0.62,95％CI(-0.80,2.03),P=0.390],the effect of intervention was unclear.Conclusion Remote intervention based on digital health technology can improve self-monitoring compliance and quality of life in lung transplant patients;applications are the optimal form of intervention.Limited by the quality and quantity of included studies and the heterogeneity of study results,more high-quality studies are needed to further verify the effects of digital health technology on readmission rates,anxiety and depression of lung transplant patients.

Objective To explore and implement a differentiated management strategy for multi-campus hospitals to improve patient experience and satisfaction,and achieve the goal of homogenized management.Methods In December 2021,the Picker Patient Experience Questionnaire was used to survey the patient experience at 3 campuses of a tertiary A hospital in Hangzhou,and the reasons for the differences were analyzed.Based on policy document reviews,special group discussions,and expert meetings,differentiated management strategy for multi-campus hospitals was formulated.The patient experience and satisfaction before(December 2021)and after(December 2023)the implementation were compared.Results After the application of the one-hospital multi-campus difference management strategy,the overall medical experience score of the patients in the 3 campus was(58.54±2.36)points,which was higher than(58.13±3.24)points before the application(t=-3.223,P=0.001),and there was no statistically significant differences among the patients in the 3 campuses(F=0.781,P=0.458).After the application of the management strategy,the overall satisfaction score of the patients in the 3 campus was(98.44±6.22)points,which was higher than(97.98±6.87)points before the application of the management strategy(t=-2.490,P=0.013),and there was no statistical significance among the patients in the 3 campus(F=1.128,P=0.324).The number of banners and letters of commendation received by the 3 campuses increased from 1 661 before the application to 2 190 after the application,with a growth rate of 31.85％.Conclusion Differentiated management in a multi-campus hospital,aiming at homogenized quality through differentiated strategies,is practicable and can significantly improve the patient experience and satisfaction across different campuses.

Objective To investigate the incidence and risk factors of post-transplant diabetes mellitus(PTDM)in adult lung transplant recipients.Methods Conducting a convenience sampling method,we retrospectively analyzed the clinical data of lung transplant recipients from January 2020 to December 2022 at a tertiary A hospital in Hangzhou,Zhejiang Province.According to the PTDM diagnostic criteria,lung transplant recipients are divided into a PTDM group and a non-PTDM group.The incidence rate of PTDM is calculated,and the influencing factors for PTDM occurrence are analyzed using both univariate and multivariate logistic regression methods.Results A total of 140 patients were included in this study,and 54 lung transplant recipients developed PTDM within 6 months,with an incidence of 38.57％.Univariate analysis showed that there were significant differences in age,gender,BMI,smoking history,pre-operative glycated albumin,pre-operative fasting blood glucose,early post-operative blood glucose and pre-operative creatinine between the 2 groups(P＜0.05).Multivariate Logistic analysis showed that gender(OR=5.283),BMI(OR=6.122),pre-operative glycated albumin(OR=1.330),and early post-operative blood glucose(0R=1.444)were the influencing factors.Conclusion Lung transplant recipients who were male,BMI ≥24.0,with high levels of glycated albumin before surgery,and high blood sugar early after surgery had a higher risk of developing PTDM.Clinical nurses can formulate relevant nursing measures according to the influencing factors to prevent the occurrence of PTDM.

Objective To analyze and discuss the medication rule of professor Ruan Yan in the treatment of children with allergic rhinitis by using data mining method,and to provide reference for the clinical research and patented drugs development for the treatment of children with allergic rhinitis.Methods The outpatient medical records of professor Ruan Yan for the treatment of children with allergic rhinitis were collected.Microsoft Excel 2010 software was used for frequency statistics.SPSS Clementine 12.0 software was used for association rule analysis,cluster analysis and factor analysis to obtain the data.The frequency of use of various drugs and the association rules between drugs were obtained.Then the medication rules in professor Ruan Yan's prescription were analyzed.Results A total of 308 Chinese medicine compounds were included,involving 80 kinds of Chinese medicines,among which relieving drugs and qi-invigorating herbs were high-frequently used.The distribution of traditional Chinese medicine syndrome types was mainly characterized by lung-qi deficiency-cold syndrome and lung-spleen qi deficiency syndrome.The medicinal properties were mainly spicy,warm and sweet,and most of them belonged to the lung,spleen and stomach meridians.Five core prescriptions were extracted by factor analysis.Four drug combinations were obtained by systematic cluster analysis.Conclusion Ventilating lung and opening the orifices,expelling wind and removing cold,strengthening the spleen and replenishing qi are basic therapeutic principles for professor Ruan Yan in the treatment of children with allergic rhinitis.The treatment mainly focused on dispelling evil,ventilating lung and opening the orifices,expelling wind and removing cold during the acute stage of allergic rhinitis.In the remission period,according to the principle of"treating disease must be based on its origin",the treatment should enhance children's physical fitness,tonify lung and strengthen spleen,thereby reducing recurrence.

Objective To investigate the improving effect and mechanism of the traditional Chinese herbal medicine Glabridin(GLA)on cognitive impairment in Parkinson's disease(PD)mice induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP),and its protective effect on the cerebral cortex and hippocampus through affecting the extracellular regulated protein kinases(ERK)signaling pathway involved in the regulation of neural plasticity.Methods A total of 120 C57BL//6N mice were randomly divided into control group,model group,GLA control group and MPTP+GLA low,medium and high-dose groups,with 20 mice in each group.The mouse PD model was established by intraperitoneal injection of MPTP 20 mg/kg,and the control group was injected with the same dose of normal saline.The GLA control group was given 50 mg/kg GLA by gavage;the MPTP+GLA low,medium and high dose groups were given 20,30 and 50 mg/kg GLA by gavage 1 hour after each MPTP administration,once a day for 7 consecutive days.The learning and memory abilities of the mice in each group and the pathological changes of hippocampal tissue were observed,as well as the changes in the contents of tumor necrosis factor-α(TNF-α),interleukin-18(IL-18),malondialdehyde(MDA),superoxide dismutase(SOD),tyrosine hydroxylase(TH)and protein expression levels of phosphorylated-ERK 1/2(p-ERK1/2)in the cerebral cortex.Results Compared with the control group,the levels of MDA and TNF-α,IL-18 in the cerebral cortex of the model group were significantly increased[MDA(nmol/mg):4.68±0.51 vs.2.05±0.22,TNF-α(μg/L):116.87±15.65 vs.48.52±7.83,IL-18(μg/L):57.52±6.89 vs.24.26±1.89,all P<0.05],while the activity of SOD was significantly decreased(U/mg:77.84±7.84 vs.130.89±18.56,P<0.05).Compared with the model group,the contents of TNF-α,IL-18,and MDA in each MPTP+GLA group were significantly decreased,while the activity of SOD was significantly increased(all P<0.05),and the change in the high-dose MPTP+GLA group was more obvious.The learning and memory ability of the high-dose MPTP+GLA group was significantly improved,the number of neurons in the hippocampus tissue decreased,the neurodegeneration was improved,and the glial cell proliferation was reduced.The results of immunohistochemistry showed that compared with the model group,the loss of TH positive cells in the high-dose MPTP+GLA group was significantly reduced[absorbance(A value):cerebral cortex was 39.14±3.25 vs.23.14±3.1,hippocampus was 72.14±4.25 vs.52.16±3.32,both P<0.05],and the expression of p-ERK1/2 positive cells was significantly inhibited(A value:cerebral cortex was 63.91±3.55 vs.88.35±6.41,hippocampus was 73.36±3.52 vs.93.25±6.73,both P<0.05).Western blotting showed that compared with the model group,the protein expression level of cerebral cortex and hippocampus TH in the high-dose MPTP+GLA group was significantly increased(gray value:cerebral cortex was 0.71±0.09 vs.0.53±0.06,hippocampus was 0.68±0.06 vs.0.45±0.03,both P<0.05),and the protein expression level of p-ERK1/2 was significantly inhibited(gray value:cerebral cortex was 0.76±0.10 vs.0.96±0.08,hippocampus was 0.74±0.06 vs.0.96±0.12,both P<0.05).Conclusions The traditional Chinese medicine GLA can improve the learning and memory ability of MPTP-induced PD mice,as well as prevent and treat MPTP-induced neuronal damage and glial cell proliferation.The ERK signaling pathway is associated with neural damage in PD brain tissue.GLA protects the learning and memory ability of MPTP-induced PD mice by inhibiting the ERK signaling pathway.

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.
