Lung cancer remains one of the leading causes of cancer-related morbidity and mortality worldwide, and its treatment continues to face major challenges such as therapeutic resistance and tumor recurrence. Pyroptosis, a newly characterized form of programmed cell death, induces tumor cell death through gasdermin-mediated membrane pore formation and is accompanied by the release of inflammatory mediators, thereby playing complex roles in lung cancer initiation, progression, and modulation of the tumor microenvironment. Active components and herbal formulas derived from traditional Chinese medicine can modulate pyroptosis-related signaling pathways through multi-target mechanisms, showing potential advantages in inducing lung cancer cell death, inhibiting proliferation and migration, and reversing chemoresistance. This review systematically summarizes relevant studies from domestic and international sources, focusing on the molecular mechanisms of pyroptosis, its roles in lung cancer development and tumor microenvironment remodeling, and the current research progress on traditional Chinese medicine-based interventions targeting pyroptosis, with the aim of providing references for the prevention and treatment of lung cancer using traditional Chinese medicine.

Objective:To investigate the clinical features and prognosis of male with anti-melanoma differentiation-associated gene 5 (MDA5) autoantibody.Methods:The clinical data of 246 patients with DM and anti-MDA5 autoantibodies hospitalized by Jiangsu Myositis Cooperation Group from 2017 to 2020 were collected and retrospectively analyzed. Chi-square test was performed to compared between counting data groups; Quantitative data were expressed by M ( Q1, Q3), and rank sum test was used for comparison between groups; Single factor survival analysis was performed by Kaplan-Meier method and Log rank test; Cox regression analysis were used for multivariate survival analysis. Results:①The male group had a higher proportion of rash at the sun exposure area [67.1%(47/70) vs 52.8%(93/176), χ2=4.18, P=0.041] and V-sign [50.0%(35/70) vs 30.7%(54/176), χ2=8.09, P=0.004] than the female group. The male group had higher levels of creatine kinase [112(18, 981)U/L vs 57 (13.6, 1 433)U/L, Z=-3.50, P<0.001] and ferritin [1 500 (166, 32 716)ng/ml vs 569 (18, 14 839)ng/ml, Z=-5.85, P<0.001] than the female group. The proportion of ILD [40.0%(28/70) vs 59.7%(105/176), χ2=7.82, P=0.020] patients and the red blood cell sedimentation rate[31.0(4.0, 101.5)mm/1 h vs 43.4(5.0, 126.5)mm/1 h, Z=-2.22, P=0.026] in the male group was lower than that of the female group, but the proportion of rapidly progressive interstitial lung disease (PR-ILD) [47.1%(33/70) vs 31.3%(55/176), χ2=5.51, P=0.019] was higher than that of the female group. ②In male patients with positive anti-MDA5 antibodies,the death group had a shorter course of disease[1.0(1.0, 3.0) month vs 2.5(0.5,84) month, Z=-3.07, P=0.002], the incidence of arthritis [16.7%(4/24) vs 42.2%(19/45), χ2=4.60, P=0.032] were low than those in survival group,while aspartate aminotransferase (AST)[64(22.1, 565)U/L vs 51(14,601)U/L, Z=-2.42, P=0.016], lactate dehydrogenase (LDH) [485(24,1 464)U/L vs 352(170, 1 213)U/L, Z=-3.38, P=0.001], C-reactive protein (CRP) [11.6(2.9, 61.7) mg/L vs 4.95(0.6, 86.4) mg/L, Z=-1.96, P=0.050], and ferritin levels [2 000(681, 7 676) vs 1 125 (166, 32 716)ng/ml, Z=-3.18, P=0.001] were higher than those in the survival group, and RP-ILD [95.8%(23/24) vs 22.2%(10/45), χ2=33.99, P<0.001] occurred at a significantly higher rate. ③Cox regression analysis indicated that the course of disease LDH level, and RP-ILD were related factors for the prognosis of male anti-MDA5 antibodies [ HR (95% CI)=0.203(0.077, 0.534), P=0.001; HR (95% CI)=1.002(1.001, 1.004), P=0.003; HR (95% CI)=95.674 (10.872, 841.904), P<0.001]. Conclusion:The clinical manifestations of male anti-MDA5 antibody-positive patients are different from those of female. The incidence of ILD is low, but the proportion of PR-ILD is high. The course of disease, serum LDH level, and RP-ILD are prognostic factors of male anti-MDA5 antibody-positive patients.

Artificial intelligence (AI) has important significance and great promise in the pathological diagnosis,imaging diagnosis,prognosis prediction,and molecular subtyping of prostate cancer (PCa). This review focuses on the progress of AI for the diagnosis and molecular classification of PCa,and briefly introduces the application of AI in the pathological diagnosis of needle biopsy and Gleason grading,pathological diagnosis and grading after prostatectomy,and prognosis prediction of PCa patients based on pathological sections. For the pathological diagnosis of needle biopsy and Gleason grading,AI has already comparable to general pathologists;for the pathological diagnosis and grading after prostatectomy,AI can accurately grade and classify tumors;and for the prognosis prediction of PCa patients,AI can directly extract relevant prognostic information from pathological tissue sections for prognosis prediction. In addition,AI can also predict gene mutations in PCa patients and suggest the probability of gene mutation by analyzing the pathological sections.

ObjectiveTo establish a model of inflammasome activation induced by psoralidin based on bone marrow-derived macrophages （BMDM） in mice， and to explore the immunomodulatory effects of psoralidin combined with echinatin. MethodLipopolysaccharide （LPS） and psoralidin were used to activate inflammasomes， and after 4 h LPS stimulation， echinatin （40 μmol·L^-1） was administered for pre-protection for 1 h， followed by stimulation with psoralidin （10， 20， 40 μmol·L^-1） for 4 h. The protein expression of Caspase-1 p20 in cell supernatant and precursor （pro）-Caspase-1 and pro-interleukin（IL）-1β in cell lysate were simultaneously detected by Western blot. Enzyme-linked immunosorbent assay （ELISA） was adopted to determine the content of IL-β and TNF-α in the supernatant of BMDM. ResultWestern blot revealed that compared with the conditions in the control group， the maturation of psoralidin-induced pro-Caspase-1 and the secretion of IL-1β was inhibited by echinatin （P<0.05，P<0.01）. ELISA showed that the production of IL-1β and TNF-α was enhanced by psoralidin of different concentrations （P<0.05，P<0.01） compared with the condition in the control group. In addition， compared with the psoralidin group， the psoralidin combined with echinatin group reduced the secretion of IL-1β and TNF-α （P<0.01）. ConclusionEchinatin could significantly inhibited the excessive immune-inflammatory response mediated by psoralidin， and thus achieve the effect of toxicity reduction. The present study explored the toxicity-reducing effect of psoralidin combined with echiantin， providing a basis for safe clinical application.

Objective To compare the efficacy and safety of percutaneous nephrolithotomy ( PCNL) in modified supine Valdivia and traditional prone positions for the treatment of renal stones.Methods Clinical data of 80 consecutive patients with renal calculi who accepted PCNL from December 2012 to September 2014 were retrospectively reviewed.They were divided into modified supine Valdivia group ( n=44) and prone position group (n=36) according to the position during surgery.There was no significant difference between the 2 groups in age, sex, ASA class, stone location and size (P>0.05).Total operative time, ratio of multi-access, blood loss, perioperative complications and stone-free rate were compared between the 2 groups.Results All punctures were performed successfully.No case was converted to open surgery.No severe complications such as colon injury, pleura or peritoneum perforation, or death occurred intra-and post-operatively.In prone position, 1 patient was found to develop high intra-trachea pressure because of large stone burden and prolonged operative time (130 min).This procedure was stopped and the patient received the second session of PCNL 1 week later.The mean total operative time was significantly shorter in the modified supine than in the prone position ( 67.7 ±24.5 min versus 91.5 ±29.8 min, P<0.05).There were no significant differences in ratio of multi-access (14% versus 22%), mean blood loss (1.3 ±0.2 g/L versus 1.4 ±0.7 g/L), incidence of complications (18% versus 19%), and stone clearance rate ( 80% versus 86%) between the 2 groups ( P >0.05 ) .Conclusion PCNL in modified supine Valdivia is as safe and effective as that of prone position for the treatment of renal stones, but the former is more time-saving than the latter.

Objective Wnt signaling plays an important role in the development and progression of renal cell carcinoma (RCC).This study aimed to evaluate the effects of the Wnt signaling inhibitor 15-oxospiramilactone on the proliferation , migration, cell apoptosis, and cycles of the human RCC cell line 786-0, and to investigate the possible mechanisms of this small molecule acting on RCC in ivtro. Methods We treated 786-0 cells with DMSO ( blank control group ) and 15-oxospiramilactone at the concentrations of1.25μmol/L (low 15 -OSL), 2.5μmol/L (medium 15-OSL), and 5μmol/L (high 15-OSL), respectively, for 72 hours.Then we observed the changes in the proliferation and migration of the 786-0 cells by MTT and scratch-wound assay and determined their apopto-sis and cycles by Annexin V-FITC/PI assay and flow cytometry . Results 15-oxospiramilactone significantly inhibited the growth of the 7860-cells, with the IC 50of 1.088 μmol/L at 72 hours, and decreased their migration distance (P<0.05).After 36 hours of treatment, the apoptosis rates of the 786-0 cells in the low, medium, and high 15-OSL groups were (12.17 ±0.56), (18.54 ± 1.07), and (50.74 ±1.28) %, respectively, significantly increased as compared with (7.85 ±0.42) %in the blank control group (P<0.05), and in an obviously concentration-dependent manner.15-oxospiramilactone remarkably reduced the number of cells in the G0/G1 phase and increased that in the G 2/M phase (P<0.05). Conclusion 15-oxospiramilactone can significantly inhibit the pro -liferation and migration and induce the apoptosis of 786-0cells in vitro.It may be a potential anti-RCC agent.
