The blood products industry,both domestically and internationally,exhibits distinct features in product research,development,and technological innovation.International companies possess extensive expertise in developing immunoglobulins,coagulation factors,and recombinant plasma protein products,demonstrating continuous advancements-particularly in specific immunoglobulin development,long-acting formulation optimization,and manufacturing process improvements.In recent years,Chinese enterprises have also achieved notable progress in related fields,especially in immunoglobulin process refinement and the development of novel recombinant coagulation factor products.However,there remains significant scope for improvement in areas such as the application of recombinant protein technologies,efficient utilization of plasma resources,and the adoption of advanced manufacturing techniques.Additional challenges include the accumulation of patented technologies,the supply of critical raw materials,and access to comprehensive epidemiological data.Driven by ongoing advances in gene recombination technologies,innovations in drug delivery systems,digital transformation,and the rise of personalized medicine,the blood products industry is poised for broader development prospects.To foster sustained and stable domestic industry growth and enhance global competitiveness,Chinese blood product enterprises should intensify their technological accumulation,upgrade manufacturing processes,and optimize plasma resource utilization.

Aim To explore the mechanisms of PM2.5 exposure exacerbating bleomycin(BLM)-induced idio-pathic pulmonary fibrosis(IFP)by regulating ferropto-sis via nuclear factor 2 related factor 2(Nrf2)/solute carrier family 7 member 11(SLC7A11)/glutathione peroxidase(GPX)4 axis.Methods Forty C57BL/6J mice were randomized into the control,BLM,PM2.5,BLM+PM2.5 and sulforaphane(SFN,Nrf2 agonist)groups,with eight mice in each group.PM2.5 expo-sures were conducted to the BLM-induced IPF mice for two weeks.The lung function was measured,and the content of hydroxyproline(HYP)in lung tissue and the pathomorphology of lungs were observed.Reactive oxygen species(ROS),malondialdehyde(MDA),ferrous ion(Fe2+)and glutathione(GSH)of the lung tissue were measured by ELISA.The mRNA and pro-teins levels of Nrf2,SLC7A11,GPX4,collagen typeⅠ(COL-1),α-smooth muscle actin(α-SMA)were measured by quantitative polymerase chain reaction(qPCR)and Western blot.Results Compared with the control group,the lung function of mice was signif-icantly reduced(P＜0.01)in the BLM and PM2.5 groups,while lung tissue showed the characteristic pathological changes of pulmonary fibrosis such as a large number of inflammatory cell infiltration,alveolar wall fracture,thickening,collagen deposition,and sig-nificantly increased HYP,Fe2+,ROS,MDA(P＜0.05,P＜0.01),genes and proteins of COL-1,α-SMA(P＜0.01);and decreased GSH,Nrf2,SLC7A11,GPX4 genes and proteins(P＜0.05,P＜0.01).The above-mentioned lesions were markedly aggravated in the BLM+PM2.5 group compared with the BLM(P＜0.05)and PM2.5 groups(P＜0.01),and were also improved in the SFN group(P＜0.05,P＜0.01).Conclusions PM2.5 exposures can exac-erbate IPF-induced IPF in mice,and the regulating of Nrf2/SLC7 A1 1/GPX4 axis and ferroptosis might be in-volved in the related mechanisms.

Objective To explore the clinical efficacy of applying exoskeleton robots in lower limb functional rehabilitation for patients after minimally invasive surgery for cervical spondylotic myelopathy(CSM).Methods A retrospective analysis was conducted on the clinical data of 56 patients who underwent spinal endoscopic minimally invasive surgery between April 2021 and October 2022.Based on the rehabilitation methods,patients were divided into the observation group(robot-assisted rehabilitation group)and the control group(conventional rehabilitation group).The Japanese Orthopaedic Association(JOA)scores for cervical spinal cord function,lower limb somatosensory evoked potential amplitudes,and gait analysis indicators(step frequency,walking speed,and stance phase ratio)were assessed preoperatively,4 weeks postoperatively,and 8 weeks postoperatively.Results In 4 and 8 weeks after surgery,both groups showed significant improvements in JOA scores,lower-limb somatosensory evoked potential amplitudes,and gait parameters(step frequency,walking speed,and stance phase ratio)com-pared with preoperative data(P<0.05).Furthermore,the improvements in JOA scores,somatosensory evoked potential amplitudes,and gait parameters in the observation group were significantly greater than those in the control group at both 4 and 8 weeks postoperatively(P<0.05).However,at the 2-year follow-up,there were no statistically significant differences(P>0.05)between the two groups in any of these measures.Conclusions Rehabilitation using lower limb exoskeleton robots can accelerate spinal cord function recovery and improve lower limb walking ability in patients after minimally invasive surgery for CSM,demonstrating superior short-term clinical efficacy com-pared to conventional rehabilitation.However,no significant differences were observed between the two methods during long-term follow-up.

The incidence rate of kidney diseases in China has always remained high.At present,the clinical treat-ment mainly focuses on symptomatic treatment to delay the progression of the disease,and there is a lack of eco-nomical and effective treatment methods.MicroRNA plays an important regulatory role in the occurrence and devel-opment of diseases.This study aims to explore the role and regulatory mechanism of miR-142a-3p in adriamycin(ADR)-induced renal tubular epithelial cell(TCMK-1)injury,with a focus on its potential as a therapeutic target for ADR nephropathy.First,cell viability was assessed using the CCK-8 kit,and a mouse renal tubular epithelial cell model induced by ADR was established.Subsequently,alterations in miR-142a-3p and its target gene ATG16L1 mRNA levels were quantified using RT-qPCR.Western blotting was used to detect the protein levels of autophagy marker proteins and pyroptosis marker proteins.Monodansylcadaverin(MDC)staining was performed and the autophagy of cells was detected by flow cytometry.The results showed that the relative expression of miR-142a-3p in TCMK-1 cells induced by ADR was increased and the relative expression of its target gene ATG16L1 was decreased(P＜0.0001).Western blotting results showed that the levels of p62(P＜0.001)and pyroptosis-related proteins(P＜0.001)were increased,while the protein levels of autophagy-related proteins were decreased(P＜0.05).The flow cytometry results showed that there was no difference in the mean fluorescence intensity of autoph-agosomes between the ADR group and the autophagosome inhibitor group(3-MA group)(P＞0.05),indicating that after ADR induction,cell autophagy was inhibited and pyroptosis was enhanced.When the expression of miR-142a-3p was inhibited by transfecting miR-142a-3p inhibitor,the relative expression level of the target gene ATG16L1 was restored(P＜0.001).Western blotting showed that the protein level of p62(P＜0.01)and pyropto-sis-related proteins(P＜0.01)were decreased,and the protein level of autophagy-related proteins was restored(P＜0.001).Flow cytometry results further indicated that cell autophagy was restored(P＜0.0001).In conclusion,ADR targets A TG1 6L1 through miR-142a-3p to reduce the autophagy level of TCMK-1,and simultaneously activates GSDMD-mediated pyroptosis.

AIM:To investigate the mechanism through which aerobic exercise improves inflammatory senes-cence in SAMP8 mice via Janus kinase 3(JAK3)-signal transducer and activator of transcription 5α(STAT5α)signaling pathway and to provide novel insights for anti-inflammatory aging interventions.METHODS:Sixteen 28-week-old SAMP8 mice were randomly divided into model(Mod)group and exercise(Exe)group,with 8 mice in each group.Addi-tionally,8 senile SAMR1 mice served as control(Con)group.The mice in Exe group underwent an 8-week aerobic training regimen on a treadmill.We monitored the changes in hair quality and body weight,immune organ indexes,histomorpho-logical alterations in immune organs,the expression levels of spleen aging marker P16,and the serum and spleen levels of inflammatory factors[tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)]and aging indicator IL-2.Moreover,we examined the alterations in the mRNA and protein expression of IL-2,JAK3 and STAT5α in the spleen.RESULTS:(1)Compared with Con group,the mice in Mod group exhibited decreased hair luster and volume,with some instances of alopecia areata,increased body weight,markedly reduced spleen and thymus indexes,evident atrophy and senescence of immune organs,and markedly decreased concentration of IL-2 in the serum and spleen.The expression of P16 in the spleen,and the serum and spleen levels of inflammatory factors TNF-α and IL-1β were significantly increased.The mRNA expression of IL-2 and IL-2 receptor subunit gamma(IL-2RG)in the spleen was markedly decreased,whereas that of JAK3 and STAT5α was markedly increased.Furthermore,the protein expression of IL-2 in the spleen was markedly de-creased,whereas that of STAT5α and JAK3 was markedly increased.(2)Compared with Mod group,the mice in Exe group showed relatively vigorous hair growth and better hair luster,lower body weight,markedly increased spleen and thy-mus indexes,and delayed immune organ aging.The concentration of IL-2 in the serum and spleen was markedly in-creased,while the expression of P16 in the spleen was markedly decreased.The levels of TNF-α and IL-1β in the serum and spleen were markedly decreased.The mRNA expression of IL-2 and IL-2RG in the spleen was markedly increased,whereas that of JAK3 and STAT5α was markedly decreased.The protein levels of IL-2 were markedly increased,whereas those of STAT5α and JAK3 were markedly decreased.CONCLUSION:Aerobic exercise can delay inflammatory aging in mice possibly through the JAK3-STAT5α signaling pathway.
