Objective To investigate programmed death including necroptosis,apoptosis,autophagy,ferroptosis,and pyroptosis in bone marrow megakaryocytes of mice during sepsis and its impact on platelet production capacity and coagulation function in mice.Methods C57BL/6J mice were randomly divided into a sham operation group(sham group)and a sepsis model group(CLP group).Peripheral blood platelets and coagulation function were measured by abdominal aortic blood sampling at 24 h postoperatively in both sham and CLP groups.After the mice were sacrificed,long bones of both lower limbs were taken,and bone marrow megakaryocytes were extracted using megakaryocyte separation solution and immunomagnetic bead separation.Laser confocal microscopy was used to observe the activation of programmed death-related marker molecules in mouse bone marrow megakaryocytes.Flow cytometry was used to detect programmed death rate,platelet production phenotype,and platelet surface markers(CD41,CD42b,CD61)of megakaryocytes.Western blotting was used to detect the expression of programmed death-related proteins in megakaryocytes.Results Compared with the sham group,the CLP group showed significant decreases in the number of platelets during acute sepsis(24 h)(P<0.000 1),significant increases in platelet distri-bution width(PDW)and mean platelet volume(MPV)(P<0.01),significant prolonging of thrombin time(TT),prothrombin time(PT),and activated partial thromboplastin time(APTT)(P<0.000 1,P<0.001,P<0.01),and significant reduction in fibrinogen(Fib)(P<0.000 1).Compared with the Con/sham group,the LPS/CLP group exhibited significant increases in the platelet production phenotype of megakaryocyte,the number of PLP in the supernatant,and the expression levels of platelet surface markers(CD41,CD42b,CD61).The rates of megakaryocyte necroptosis/apoptosis,pyroptosis,and ferroptosis were significantly elevated at 24 h post-CLP surgery.Laser confo-cal microscopy showed significant activation of LC3,P-MLKL,Caspase-1,and Fe2+in megakaryocytes of mice after CLP surgery.Western blotting results revealed that the CLP group exhibited a significant increase in the activa-tion rate of necroptosis-related protein P-MLKL(P<0.001),a significant increase in the cleavage of pyroptosis-related proteins GSDMD and GSDMD-N(P<0.01,P<0.001,respectively),a significant increase in the expres-sion of ferroptosis-related protein ACSL4(P<0.01),and a significant decrease in the expression of GPX4(P<0.01)compared to the sham group.Additionally,the CLP group demonstrated significant increases in the expression of apoptosis-related protein Bax,the cleavage of autophagy-related protein LC3B-Ⅱ,and the expression of P62(P<0.05,P<0.001,P<0.001,respectively).Inhibition of apoptosis with programmed cell death inhibitors decreased platelet production function of megakaryocyte,while inhibition of necroptosis and pyroptosis had limited effects on platelet production function of megakaryocyte.Inhibition of ferroptosis and autophagy enhanced platelet production function of megakaryocyte.Conclusion Significant programmed death of megakaryocytes was observed during the acute phase of sepsis(24 h).Among those megakaryocytes,apoptosis is an important mechanism for the differentia-tion of platelet production phenotype and increased platelet production capacity of megakaryocyte.Overactive autophagy and ferroptosis in megakaryocytes lead to megakaryocyte dysfunction,which is an important mechanism for coagulation abnormalities in sepsis.

Autophagy is a fundamental biological metabolic process involved in immune defense, material metabolism, and homeostasis and closely linked to immune regulation. Systemic lupus erythematosus (SLE) is a widespread connective tissue disorder primarily resulting from immune system imbalance. Due to the immune system's failure to recognize its own substances, it generates autoantibodies that can affect various tissues and organs, leading to diverse clinical manifestations. The pathogenesis and treatment of SLE are currently under extensive investigation. In normal metabolic processes, autophagy engages in both innate and adaptive immunity, regulates the immune response, and is crucial for maintaining normal immune function and the body's internal homeostasis. Research has indicated that SLE patients exhibit immune dysfunction and altered autophagy levels. Modulating autophagy expression can influence immune system functionality and alleviate SLE symptoms. Additionally, autophagy aids in the innate immune response and adaptive immunity by clearing metabolites and regulating the life cycle of immune cells. Studies suggest that drugs targeting autophagy can positively influence the progression of SLE. This article reviews advancements in research regarding the impact of autophagy on the pathogenesis of SLE through the regulation of immune system functions.

【Objective】 To explore the correlation between CSAG1 expression and the prognosis and tumor-infiltrating lymphocytes in renal clear cell carcinoma (RCCC), and to predict the survival and tumor progression. 【Methods】 The gene expression profiles and clinical information of CSAG1 were downloaded from the Cancer Genome Atlas (TCGA). Based on the differential mRNA expression, GO annotation and KEGG pathway analysis were performed. The relationship between CSAG1 and tumor immune infiltration was assessed with Tumor Immunoassay Resource (Timer 2.0) database. The mRNA expression of CSAG1 in human RCCC specimens was validated with qRT-PCR. 【Results】 CSAG1 expression was significantly higher in RCCC tissues than in normal tissues (P<0.05). The qRT-PCR results revealed that the mRNA level of CSAG1 was consistent with that predicted by bioinformatic analysis. The KEGG analysis and GO annotation indicated high GSAG1 expression in RCCC was related to transmembrane transport, tricarboxylic acid cycle and lysosome. CSAG1 expression was positively related to the infiltration of pDC, aDC, CD8⁺ T cells, cytotoxic cells, TFH, TH1 cells, Tem, NK CD56^dm cells, Treg and T cells, but negatively correlated with macrophage infiltration. 【Conclusion】 CSAG1 may be associated with poor prognosis of RCCC and become a potential immunotherapy target.

Objective To study the expression of serum interleukin(IL)-17A,calcium binding protein S100A8 and S100A9 in children with severe Mycoplasma pneumoniae pneumonia(SMPP)and their prognostic significance.Methods A total of 116 children with SMPP who were diagnosed and treated in this hospital from March 2019 to March 2021 were enrolled as the SMPP group.According to the pediatric critical cases score,the SMPP children divided into non-critical group(43 cases),critial group(40 cases),extremely critical group(33 cases).According to the prognosis of 28 d after admission,the SMPP children were divided into a good prognosis group with 82 children and a poor prognosis group with 34 children.A total of 60 physical ex-amination of healthy children in the same hospital during the same period were enrolled as the control group.The levels of serum IL-17A,S100A8,S100A9,procalcitonin(PCT),C-reactive protein(CRP),IL-6 and tumor necrosis factor(TNF)-α were detected in each group.Pearson correlation analysis was used to analyze the cor-relation between serum levels of IL-17A,S100A8,S100A9 and PCT,CRP,IL-6,and TNF-α.Multivariate Lo-gistic regression analysis was used to analyze the factors affecting the poor prognosis of children with SMPP.The receiver operating characteristic(ROC)curve was used to analyze the value of each index in predicting the poor prognosis of children with SMPP.Results The SMPP group had significantly higher serum levels of IL-17A,S100A8,S100A9,PCT,CRP,IL-6,and TNF-α than the control group(P<0.05).In children with SMPP,the serum levels of IL-17A,S100A8,and S100A9 were positively correlated with PCT,CRP,IL-6,and TNF-α(P<0.05).The serum levels of IL-17A,S100A8 and S100A9 in extremely critical group were signifi-cantly higher than those in critical group and non-critical group(P<0.05).Elevated serum levels of IL-17A,S100A8 and S100A9 were independent risk factors for poor prognosis in children with SMPP.The area under the curve(AUC)of combined detection of serum IL-17A,S100A8 and S100A9 for predicting poor prognosis in children with SMPP was 0.895,which was higher than that of single detection of serum IL-17A,S100A8 and S100A9(0.833,0.764,0.810),the differences were all statistically significant(Z=3.780,6.723,5.012,P<0.059).The sensitivity and specificity of combined detection were 0.891 and 0.755,respectively.Conclu-sion The serum levels of IL-17A,S100A8 and S100A9 are increased in children with SMPP,which are related to the severity of SMPP.The combined detection of the three indicators has a high predictive value for the poor prognosis of SMPP.

Objective To observe the effect of risperidone combined with clozapine in the treatment of vagrants with schizophrenia and its influence on social function of the patients.Methods Eighty patients with vagrant schizophrenia were selected as the study objects by a prospective randomized controlled trial,and were randomly divided into control group(40 cases)and observation group(40 cases).The control group was treated with risperidone,and the observation group was treated with risperidone and clozapine.Both groups received continuous treatment for 8 weeks.The clinical effects of the two groups were observed.The activities of daily living,rehabilitation[Inpatient Psychiatric Rehabilitation Efficacy Rating Scale(IPROS)score],social function,myocardial enzyme profile[lactate dehydrogenase(LDH),creatine kinase(CK),creatine kinase isoenzyme(CK-MB)]in the two groups before treatment and eight weeks after treatment were compared.The adverse reactions of the two groups were statistically analyzed.Results The total effective rate of treatment in the obser-vation group was higher than that of the control group(90.00％versus 72.50％,P＜0.05).After eight weeks of treatment,the abilities of daily living and social function of the two groups were stron-ger than before treatment,and the observation group was stronger than the control group.At 8 weeks of treatment,IPROS scores in two groups were lower than before treatment,and observation group was lower than control group(P＜0.05).After 8 weeks of treatment,LDH,CK and CK-MB levels in two groups were higher than before treatment(P＜0.05),but there was no statistical significant between-group difference(P＞0.05).Conclusion Risperidone combined with clozapine has a significant effect in thetreatment of vagrants with schizophrenia,which can enhance the patients'daily living ability and social ability,improve the rehabilitation status,and does not increase the adverse reactions.

Objective:To investigate the influence of different degrees of facet joint arthropathy on the indirect decompression effect of crenel lumbar interbody fusion (CLIF), and the clinical outcomes of CLIF for the treatment of lumbar spinal stenosis with severe facet joint arthropathy (grade 3).Methods:This study reviewed a total of 269 surgical segments in 156 patients with lumbar spinal stenosis treated with CLIF technique from November 2016 to February 2020. According to preoperative CT images, the facet joint was graded according to Pathria classification. There are 19 segments with grade 0, 156 segments with grade 1, 67 segments with grade 2, and 27 segments with grade 3. Radiographic parameters included disc angle, anterior and posterior disc height, and bilateral intervertebral foramen height on CT, and the midsagittal canal diameter and axial central canal area. In 30 patients with at least one segment of grade 3, the clinical efficacy was assessed using visual analogue scale (VAS) and Oswestry disability index (ODI).Results:The average the anterior and posterior intervertebral space height, intervertebral space angle, height of bilateral intervertebral foramina, spinal canal sagittal diameter and spinal canal area were significantly improved after the operation of grade 3 facet joint degeneration segment compared to preoperation. The preoperative mean spinal canal sagittal diameter and spinal canal area of grade 3 facet joint degeneration segment were significantly less than grade 1 and grade 2. The average change of spinal canal area after grade 3 articular degeneration was significantly less than that of grade 1 and 2, but there was no significant difference with that of grade 0. The posterior decompression rate was 55.56% (15/27) for grade 3, 35.82% (24/67) for grade 2, 16.03% (25/156) for grade 1, and 21.05% (4/19) for grade 0. The posterior decompression rate of grade 3 articular process degeneration was significantly higher than that of other grades ( P<0.001). Severe lateral recess stenosis and 24.24% of severe intervertebral foraminal stenosis were found in 81.48% of grade 3 degenerative segment. The 23 patients were followed up with an average of 21.62±6.52 months, and the average improvement of ODI was 24.10%±11.09%; the average VAS for leg pain and back pain were improved significantly. Conclusion:The degrees of facet joint degeneration do not prevent intervertebral space distraction of CLIF. However, because segments with severe facet joint arthropathy were usually associated with severe spinal canal stenosis, CLIF had a high rate of second-stage posterior decompression in the treatment of lumbar spinal stenosis with severe facet joint arthropathy.
