After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.

Radiotherapy-induced late effects(RILE)or delayed reactions have significant impacts on patients'long-term quality of life.However,current understanding of their developmental mechanisms remains limited,with a lack of effective risk prediction models and preventive interventions.Radiobiological studies and radiation-induced senescence models have revealed that radiotherapy can alter the epigenetic characteristics in late-responding tissue cells,leading to derepression of retrotransposable elements(particularly endogenous retroviral elements),subsequent activation of cytoplasmic nucleic acid sensor systems(cGAS-STING,MDA5/RIG-I-MAVS)and type Ⅰ interferon-mediated immune-inflammatory responses.This review summarized relevant research findings,proposing that the autoimmune-like inflammatory response induced by the'radiotherapy-epigenetic alteration-retrotransposable element activation'cascade is an underinvestigated mechanistic basis in the development of RILE.Constructing risk prediction models for late effects based on epigenetic signatures,cell type,and radiation dose,along with developing strategies to epigenetically suppress retrotransposable element expression,holds promise for preventing or mitigating RILE.

Objective:To analyze the trend of infertility disease burden from 1990 to 2019 and predict the age-standardized prevalence rate (ASPR) and age-standardized disability-adjusted life-year (DALY) rate of male and female infertility for 2020—2029, providing a certain reference for the prevention and treatment of infertility diseases.Methods:Based on the Global Burden of Disease 2019, prevalence, ASPR, DALY rate, and age-standardized DALY rate were used to evaluate the global burden of infertility comprehensively. The estimated annual percentage change was used to describe trends in the disease burden of infertility in 21 regions worldwide. The Bayesian age period cohort model was used to predict the ASPR and age-standardized DALY rate for male and female infertility in 204 countries and regions from 2020 to 2029. Sensitivity analysis was performed using the autoregressive integrated moving average model.Results:The prevalence, DALY rate, ASPR and age-standardized DALY rate of global male infertility increased from 319.52 per 100 000,1.82 per 100 000, 2 856.53 per 100 000, and 16.19 per 100 000 in 1990 to 565.30 per 100 000, 3.22 per 100 000, 3 398.53 per 100 000, and 19.36 per 100 000 in 2019, respectively. The prevalence, DALY rate, ASPR, and age-standardized DALY rate of global female infertility increased from 656.67 per 100 000, 3.53 per 100 000, 6 036.36 per 100 000, and 32.27 per 100 000 in 1990 to 1 223.78 per 100 000, 6.59 per 10 000, 7 483.12 per 100 000, and 40.33 per 100 000 in 2019, respectively. The burden of infertility disease was the highest in men and women aged 30-34 years, and the ASPR and age-standardized DALY rates were 4 407.47 per 100 000, 25.08 per 100 000, 10 270.55 per 100 000 and 55.65 per 100 000, respectively. Only in 45-49 years of age, the prevalence of infertility (11.31 per 100 000) and DALY rate (0.06 per 100 000) in women were lower than those in men (15.68 per 100 000 and 0.08 per 100 000). In addition, the burden of infertility was the lowest in high socio-demographic index regions. Cameroon had the highest ASPR (7 652.40 per 100 000) and age-standardized DALY rate (43.94 per 100 000) for male infertility. Chinese women had the highest ASPR (20 402.30 per 100 000) and age-standardized DALY rate (106.16 per 100 000) of infertility. The forecast results show that the burden of male and female infertility diseases will increase in 204 countries and regions from 2020 to 2029.Conclusion:The burden of infertility diseases in men and women increased in 204 countries and regions from 1990 to 2019, and it is predicted that the global burden of infertility diseases will continue to rise in 2020—2029. Preliminary screening of infertility should be carried out as soon as possible, health education should be strengthened and effective prevention and treatment strategies should be formulated.

Objective:To investigate the protective effect of moxibustion on joints and its influence on the expression levels of S100 calcium binding protein A8(S100A8),S100 calcium binding protein A9(S100A9),serum amyloid A1(SAA1),and related inflammatory factors in rats with adjuvant arthritis(AA).Methods:Forty Wistar rats were randomly divided into a normal group,a model group,a moxibustion group,and a medication group,with 10 rats in each group.Except for the normal group,AA models were established in the other three groups by exposing rats to wind-cold-dampness environmental conditions combined with complete Freund's adjuvant.After successful modeling,the moxibustion group received moxibustion intervention,while the medication group was administered tripterygium glycosides tablets via oral gavage.The normal and model groups underwent similar handling and fixation without additional interventions.After 15 d of intervention,hematoxylin-eosin staining was used to assess pathological changes in the knee joint synovial membrane.Western blotting was performed to detect the protein expression of S100A8,S100A9,and SAA1 in the synovial tissue.Enzyme-linked immunosorbent assay was used to measure the serum levels of interferon(IFN)-γ,interleukin(IL)-6,and IL-23.Results:Compared to the normal group,the model group exhibited significantly increased protein expression of S100A8,S100A9,and SAA1 in the knee joint synovial tissue,as well as elevated serum levels of IFN-γ,IL-6,and IL-23(P<0.01).Histopathological analysis revealed marked synovial hyperplasia and extensive infiltration of inflammatory cells in the model group.Compared to the model group,both the moxibustion and medication groups showed significant reductions in the protein expression of S100A8,S100A9,and SAA1 in the synovial tissue,as well as decreased serum levels of IFN-γ,IL-6,and IL-23(P<0.01).Additionally,synovial tissue in these two groups displayed minimal hyperplasia and only mild inflammatory cell infiltration.Notably,compared to the moxibustion group,the medication group exhibited significantly higher protein expression of S100A9 in the synovial tissue(P<0.05),while no significant differences were observed in the expression of S100A8,SAA1,or serum levels of IFN-γ,IL-6,and IL-23(P>0.05).Both intervention groups showed comparable degrees of synovial inflammation,clear tissue structure,and no obvious hyperplasia.Conclusion:Moxibustion can alleviate joint swelling and reduce inflammatory responses in AA rats.Its mechanism may involve regulating the protein expression of S100A8,S100A9,and SAA1 in the knee joint synovial tissue.

There are different views on the theory of “spleen governs time”， which is still a hot spot in the study of Zangxiang （藏象） theory. Based on Zangxiang time-space view， it is found that the thinking mode of the spleen governing time theory follows space-time logic. It is believed that the different time views of the spleen governing time are all formed based on the space view that the spleen belongs to earth and resides in the center， and the zang time theory is developed with the unified time and space logic. Guided by Zangxiang time-space view， the origin of the spleen belonging to earth and residing in the center is traced， and the theoretical connotation and its clinical application of spleen governing time under different time-space logic are explored with reference to the four season and five zang theory， five season and five zang theory， six season and six zang theory， and eight season and eight zang theory.

AIM:To investigate the effect of Bushen formulae(BHF)on bone metabolism and its possible mechanism in ovariectomized rats with high salt intake.METHODS:According to the random number table method,80 SPF-grade Sprague-Dawley rats were divided into sham group,ovariectomy(OVX)group,medium-high-salt diet(MSD)group,high-salt diet(HSD)group,BHF group,BHF with normal saline(BHF+NS)group,BHF+MSD group,and BHF+ HSD group,with 10 rats in each group.After modeling,different diets and BHF formula interventions were administered,and the concentrations of sodium chloride added to MSD group and HSD group were 2%(w/w)and 8%(w/w),respective-ly.The dose of BHF was 7.8 g·kg-1·d-1,once a day,and the treatment lasted for 12 weeks.Bone density,bone microar-chitecture,bone parameters,bone metabolism biomarkers,bone histopathological changes,the expression of epithelial sodium channel α(ENaCα),Na-Cl cotransporter(NCC),and voltage-gated chloride channel 3(ClC-3)proteins in bone tissue were detected in each group.RESULTS:Compared with sham group,the rats in OVX group had reduced bone density and destroyed bone microstructure.Compared with OVX group,the bone microstructure in MSD and HSD groups was more significantly damaged,while the levels of bone formation markers,bone glycoprotein(BGP)and type Ⅰ procolla-gen N-terminal peptide(PINP),were significantly increased in HSD group(P<0.05).Moreover,the levels of bone re-sorption markers,such as amino-terminal cross-linked telopeptides of type Ⅰ collagen(NTX),carboxy-terminal cross-linked telopeptides of type Ⅰ collagen(CTX)and tartrate-resistant acid phosphatase(TRACP),were significantly in-creased(P<0.05),indicating that bone metabolism was in high-conversion state.High-salt diet accelerated the structural destruction of bone trabeculae,and Western blot results showed that high-salt diet caused decreases in the protein expres-sion levels of ENaCα and ClC-3 and an increase in the protein expression level of NCC in femoral tissues(P<0.05).After BHF intervention,the expression of relevant ion channels caused by high salt could be regulated to different degrees.CONCLUSION:Bushen formulae could differentially regulate the expression of relevant ion channels ENaCα,ClC-3,and NCC induced by high salt to different degrees,which has certain ameliorative and therapeutic effects on the imbalance of bone metabolism.
