Compared to traditional suturing, lung stapling using automatic staplers offers advantages such as smaller trauma, faster wound healing, ease of operation, and lower complication rates, making it widely used in clinical practice. However, there are significant differences in bronchial tissue thickness at different anatomical locations, and the market is flooded with various types of staplers. Currently, there is a lack of recommended stapling schemes for bronchial staplers at different anatomical locations. This article reviews the development and application of automatic staplers and summarizes some types of staplers that are currently used in clinical practice, with the aim of promoting the formation of individualized stapler selection protocols for minimally invasive thoracic surgery based on the Chinese population.

Monosodium urate (MSU)-induced the gouty arthritis (GA) model was used to investigate the effect of Nod-like receptor protein 3 (NLRP3) inhibitor N14 in alleviating GA. Firstly, the effect of NLRP3 inhibitor N14 on the viability of mouse monocyte macrophage J774A.1 was examined by the cell counting kit-8 (CCK-8) assay. The expression of mature interleukin 1β (IL-1β) and cysteinyl aspartate specific proteinase-1 (caspase-1) p20 in the cell supernatant and the expression of NLRP3, caspase-1 and pro-IL-1β proteins in the cell lysates was detected by Western blot for the inhibitory effect of N14 on the MSU-induced NLRP3 inflammasome activation in J774A.1 cells. Animal behavioral tests were used to detect redness, swelling, heat and pain in mice with gouty arthritis. Hematoxylin-eosin (H&E) staining revealed pathologic changes and inflammatory infiltration in foot sections. Protein expression of NLRP3, caspase-1, and pro-IL-1β in mouse hind paw tissues were assessed by Western blot. The effect of N14 on the plasma levels of alanine transaminase (ALT), aspartate transaminase (AST), creatinine (CRE), urea, and uric acid (UA) was investigated by the MSU-induced gouty arthritis model in mice. All animal experiments in this paper were approved by the Scientific Ethics Review Board of Qingdao Marine Biomedical Research Institute (grant No. E-MBWNL-2024-20). The experimental results showed that N14 did not exhibit cytotoxicity in mouse monocyte macrophage J774A.1 cells at concentrations up to 100 μmol·L^-1, and N14 effectively prevented MSU-induced activation of NLRP3 inflammasome. In the mouse gouty arthritis model, N14 significantly ameliorated the redness, swelling, heat and pain caused by GA, and down-regulated the levels of NLRP3 inflammasome-associated proteins in mouse hind paw tissues. Meanwhile, N14 appeared to be well tolerated, as it did not significantly affect various biochemical indices in mouse plasma. In conclusion, N14 effectively alleviated GA in mice by inhibiting the NLRP3 inflammasome pathway, which is important for both prevention and treatment of related diseases.

OBJECTIVE To explore the potential of Aconiti Kusnezoffii Radix in affecting diabetes mellitus type 2(T2DM) and the potential mechanism for T2DM related symptoms based on systematic pharmacology, bioinformatics, molecular docking and in vitro and in vivo experiments. METHODS The database was used to search the related chemical components of Aconiti Kusnezoffii Radix, predict the potential targets and intervene related diseases. The differential genes of T2DM relative healthy people were retrieved from GEO database, mapped with the action target of Aconiti Kusnezoffii Radix, and placed in DAVID database for biological function enrichment. The sensitivity of the target gene to T2DM was analyzed by one-way ANOVA, binary logistic regression analysis and ROC curve. The binding position and interaction force between chemical compounds of Aconiti Kusnezoffii Radix and target proteins were analyzed by molecular docking technology. The effect of Aconiti Kusnezoffii Radix and its chemical compounds on the expression of target protein was verified by T2DM model in vivo and in vitro. RESULTS Through database retrieval and analysis, 304 kinds of target related diseases(P value<0.05, FDR<0.05) were obtained, and T2DM with the highest degree value(Degree=59) was selected and analyzed. The 43 target genes were obtained from the intersection of differential genes in T2DM relatively healthy people and potential action targets of Aconiti Kusnezoffii Radix. A total of 9 genes with significant differences were obtained by one-way ANOVA, 5 meaningful genes were obtained by binary logistic regression analysis, and 3 genes with area under ROC curve AUC>0.5 were obtained. By molecular docking (+)-Isoboldine binds to proteins APEX1, CASP1 and CBFB, Napelline binds to proteins CBX1 and EHMT2 through different forces such as hydrogen bond interaction, ligand interaction, hydrophobic interaction, ionizability and electrostatic interaction, so as to increase the ability of ligands to target proteins. After 2 weeks of treatment with Aconiti Kusnezoffii Radix aqueous extract, Aconiti Kusnezoffii Radix may alleviated the symptoms of T2DM by improving peripheral neuropathy. Moreover, Aconiti Kusnezoffii Radix could affect the protein expression of APEX1, CASP1, CBFB, CBX1 and EHMT2 in rat liver tissue. The effect of (+)-Isoboldine and Napelline chemical compounds in Aconiti Kusnezoffii Radix on the target protein of the model in vitro was consistent with that in vivo. CONCLUSION It is preliminarily revealed that Aconiti Kusnezoffii Radix can be used as a potential therapeutic drug to improve T2DM peripheral neuropathy, which lays a theoretical foundation for the research and development of Chinese Mongolian medicine and the excavation of new target drugs for the treatment of T2DM.

Objective:To evaluate the effect of sleep deprivation on the expression of sirtuin 6 (SIRT6) in the cerebellum of immature mice.Methods:Fifty SPF healthy male C57BL/6 mice, aged 4 weeks, weighing 14-16 g, were divided into 2 groups ( n=25 each) using a random number table method: control group (Con group) and sleep deprivation group (SD group). The chronic sleep deprivation model was prepared by using the multi-platform water environment method, with 20 h of sleep deprivation per day for 10 consecutive days. After sleep deprivation, a balance beam experiment was performed to test the balance and coordination ability of mice. The mice were sacrificed after anesthesia and cerebellar lobular IV-VI (4-6 cb) tissues were taken for microscopic examination of the ultrastructure (with a transmission electron microscope) and for determination of the dendritic spine density of cerebellar 4-6cb Purkinje neurons (by Golgi staining), co-expression of SIRT6 and Calbindin D-28k (CbD-28k) and expression of glucose transporter Glut3 of cerebellar 4-6cb (by immunofluorescence staining). Results:Compared with group Con, the duration of passage through the balance beam was significantly prolonged, and the number of posterior foot slips was increased, the synaptic gap of cerebellar 4-6cb neurons was increased, the thickness of postsynaptic density was increased, the density of dendritic spines of Purkinje cells and the number of positive cells co-expressing SIRT6 and CbD-28k were decreased, and the expression of Glut3 was down-regulated in group SD ( P<0.05). Conclusions:The mechanism by which sleep deprivation decreases the abilities of balance and coordination is related to down-regulating SIRT6 expression in cerebellar Purkinje cells and decreasing neuronal glucose metabolism, thus damaging the synaptic plasticity of cerebellum in immature mice.

Objective To investigate the efficacy and safety of subcutaneous immunotherapy(SCIT)using dust mites in children with allergic asthma.Methods In a prospective randomized controlled study,98 children with dust mite-induced allergic asthma were randomly divided into a control group(n=49)and an SCIT group(n=49).The control group received inhaled corticosteroid treatment,while the SCIT group additionally received a standardized three-year SCIT regimen.The two groups were compared based on peripheral blood eosinophil percentage,visual analogue score(VAS),total medication score,Asthma Control Test/Childhood Asthma Control Test scores,fractional exhaled nitric oxide(FeNO),and lung function before treatment,and at 6 months,1 year,2 years,and 3 years after treatment.Adverse reactions were recorded post-injection to evaluate the safety of SCIT.Results Compared with pre-treatment levels,the SCIT group showed a significant reduction in the percentage of peripheral blood eosinophils,VAS,total medication score,and FeNO,while lung function significantly improved,and asthma control levels were better 3 years after treatment(P<0.05).Compared with the control group,the SCIT group showed more significant improvement in all evaluated indicators 3 years after treatment(P<0.05).A total of 2 744 injections were administered,resulting in 157 cases(5.72%)of local adverse reactions and 4 cases(0.15%)of systemic adverse reactions,with no severe systemic adverse events.Conclusions SCIT is an effective and safe treatment for allergic asthma in children.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective To explore the effectiveness and safety of percutaneous coronary artery shock wave balloon angioplasty(IVL)under the guidance of intravascular ultrasound(IVUS)for the treatment of severe calcification lesions in the left main artery(LM).Methods A total of 26 patients with severe LM(mouth,body,bifurcation)calcification admitted to Jiangnan University Affiliated Hospital from October 2022 to April 2024 were included,with an average age of 72.0(61.8,75.4)years.Under the guidance of IVUS,IVL was used for pre-treatment of calcified lesions,followed by percutaneous coronary intervention(PCI)with stent/drug balloon implantation.All patients were evaluated using IVUS before and after the use of IVL and after PCI.And compare the IVUS intracavity related data before and after treatment[plaque burden(PB)、minimum lumen area(MLA)、minimum lumen diameter(MLD)]and calcification fracture number,minimum stent area(MSA),stent expansion coefficient(expansion,EXP),etc.Results There were 26 patients(2 with opening lesions,7 with body lesions,and 17 with bifurcation lesions at the end of the main trunk),including 7 with stable angina pectoris(SAP),10 with unstable angina(UA),4 with acute ST-segment elevation myocardial infarction(STEMI),and 5 with non ST-segment elevation myocardial infarction(NSTEMI).The PB at the most severe site of calcification decreased by 79.50(76.00,83.75)％compared to 80.00(76.00,83.75)％after IVL(P=0.001),MLA increased by 3.39(3.14,3.68)mm2 compared to 3.38(3.14,3.67)mm2 after IVL(P=0.039),MLD increased by 3.21(3.07,3.30)mm compared to 3.20(3.07,3.30)mm after IVL(P=0.024),and there was 100％calcification rupture(1/2 cases,2/9 cases,≥3/15 cases).The stent/drug ball was successfully implanted 100％,with EXP of(89.15±4.42)％and an MSA of 7.20(6.46,7.45)mm2.No adverse events such as death,angina or recurrent myocardial infarction occurred during the 3 months follow-up after surgery.Conclusions After evaluation by IVUS and pre-treatment with IVL,PCI was successfully completed for severe calcification lesions in LM,and IVL can be used as an option for the treatment of severe calcification in LM.

AIM:To investigate of the effect of Shenqifuzheng injection(SFI)combined with PD-L1 antibody on tumor immune microenvironment and its efficacy.METHODS:A subcutaneous transplanta-tion tumor model for B16F10-LUC melanoma was created.The expression of Ki67,CD31,CD8,CD16,CD163,FOXP3,LY6C,LY6G with labeling antibodies was used to detect CD8+T cells,Treg cells,NK cells,MDSCs cells,centrocytes,and granulocytes in the tumor tissues via immunohistochemistry.Flow cy-tometry was used to measure the ratios of CD11c+,IA/IE+,and CD80+cells in splenic tissue,as well as the ratios of CD8+T,CD4+T,and Treg cells in tumor tissue.Additionally,granulocyte count and NK cell expression were analyzed.RESULTS:The immuno-histochemistry results indicate that the drug admin-istration group effectively suppressed tumor angio-genesis and cell proliferation,while decreasing the expression level of immunosuppressive cytokines CD4+T cells,Treg cells,MDSCs and centroblasts.Ad-ditionally,CD8 and NK cell infiltration was promot-ed compared to the control group.The results of the flow analysis demonstrated a significant in-crease in the expression level of CD8+T cells within tumor tissues,as well as inhibition of CD4+T,Treg,and DC cell infiltration within the spleen in the drug administration group.Additionally,the tumor volume analysis indicated that the drug administra-tion group effectively inhibited tumor growth.The flow results illustrate that the group administering treatment exhibited significant increases in CD8+T cell expression levels in tumor tissue and DC cells in the spleen.Furthermore,the treatment effec-tively inhibited the infiltration of CD4+T and Treg cells.The results also indicate that the treatment significantly reduced tumor growth,with the tumor inhibition rate being better with PD-L1 antibody alone than with the SFI group.Additionally,combin-ing drugs resulted in superior results compared to the PD-L1 antibody group alone.CONCLUSION:SFI combined with a PD-L1 antibody can have synergis-tic anti-tumor effects,potentially enhancing DC cell infiltration and promoting T cell activation.Immu-nohistochemistry results indicate a positive impact on the tumor immune microenvironment.
