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 analyze epidemiological characteristics of influenza-like illness outbreaks in mainland China during 2017-2018 surveillance season, and to provide scientific evidence for developing influenza prevention and control strategies. Methods: We collected the data on reported influenza outbreaks in 2017-2018 surveillance season from China Influenza Surveillance Information System and China Public Health Emergency Management Information System and analyzed the data of laboratory-confirmed influenza-like illness outbreaks by descriptive epidemiological methods. Results: During the surveillance season, a total of 2 398 influenza-like illness outbreaks (with 10 or more incidences in an outbreak) in mainland China were reported, involving 87 084 patients, of which 2 323 were influenza outbreaks, involving 85 531 patients. The reported influenza-like illness outbreaks occurred most frequently from November 2017 to January 2018 in both the southern and northern regions and the highest peaks were in December 2017. During the period 1 850 influenza-like illness outbreaks (77.15%) were reported in the southern region, and 548 influenza-like illness outbreaks (22.85%) were reported in the northern region. The most of the outbreaks occurred in primary, secondary schools and nursery care schools, with a total of 2 210 reports (92.16%). And the majority of the outbreaks involved 10-29 incident cases. The dominant isolated virus strains for the outbreaks were influenza B (1 505 outbreaks, 62.76% of all the outbreaks). Conclusion Seasonality of influenza outbreaks were observed in mainland China during 2017-2018 surveillance season and the reported influenza outbreaks were most frequently occurred in autumn-winter season and in southern China. Primary, secondary schools and nursery care schools are high-risk places for outbreaks, and the dominant isolated virus strains for the outbreaks were influenza B.

Objective To investigate the clinico-pathological features and renal outcomes of primary IgA nephropathy (IgAN) with glomerular IgM deposition.Methods Primary IgAN diagnosed with biopsy from January 2006 to December 2011 were recruited.Patients were divided into groups according to IgM deposition (Group A) and without IgM deposition (Group B).In addition,Group A was subdivided into two groups based on the position of IgM deposits as the mesangium (Group A1) and both mesangium and capillary wall (Group A2).Renal outcomes were defined as end stage renal disease (ESRD) and/or the doubling of baseline serum creatinine.Clinico-pathological features were retrospectively compared.Kaplan-Meier was conducted for renal outcomes,and Cox regression model was used to analyze the prognostic value of IgM deposition and the position of IgM deposition in the progression of nephropathy in IgAN patients.Results 939 patients were enrolled with 422 (44.9％) having IgM deposition (Group A).Of the 422 patients,382 patients were divided as Group A 1,whereas 40 patients were noted as Group A2.Compared to Group B,hemoglobin,serum protein,albumin and serum IgG levels in group A were significantly lower,and the cholesterol and serum IgM levels were significantly higher (all P ＜ 0.05).There was no significant difference in serum creatinine,estimated glomerular filtration rate (eGFR),urinary protein,blood pressure and uric acid between group A and B.In terms of pathological manifestations,patients in Group A exhibited more severe histological lesions including glomerular sclerosis,S1,M1 and interstitial inflammatory cell infiltration (all P＜0.05).Immunofluorescence showed that the proportion of IgG,C1q and Fg deposition in group A was significantly higher than that in group B (all P ＜ 0.05).By Kaplan-Meier,cumulative renal survival rate has no significant difference between Group A and B (Log-rank test x2=0.019,P=0.891).Univariate and muhivariable Cox regression analysis showed that IgM deposition had no significant effect on the renal progression in IgAN patients.Subgroup analysis showed that patients in Group A2 exhibited higher urine protein,creatinine and blood pressure,and lower eGFR and serum albumin,also had worse histological lesions including M1,E1 and T1-2 of Oxford classification (all P＜0.05),Immunofluorescencc showed that the proportion of IgG,C1q and Fg deposition in group A2 was significantly higher than that in group A1 (all P ＜ 0.05).By Kaplan-Meier,renal survival rates calculated from outcomes were lower in Group A2 (Log-rank test x2=1 8.207,P ＜ 0.001).In addition,IgM deposited both in the mesangium and capillary wall was a risk factor for renal progression of IgAN patients with IgM deposition by a univariate Cox hazards regression mode and multivariable-adjusted Cox models (HR=3.621,95％CI 1.924-6.814,P＜ 0.001;HR=2.309,95％CI 1.176-4.533,P=0.015respectively).Conclusions The IgAN patients with IgM deposition relatively had more severe clinicopathological changes,especially those with IgM deposited both in the mesangium and capillary wall.In this study,IgM deposition was not found to be an independent risk factor for the prognosis of kidney in IgAN patients.However,IgM deposited both in the mesangium and capillary wall was an independent risk factor for renal prognosis in IgAN patients with IgM deposition.

Objective To explore the clinicopathological features and renal outcomes of primary IgA nephropathy (IgAN) patients with chronic tonsillitis.Methods Patients with biopsyproven primary IgAN admitted to The First Affiliated Hospital,Sun Yat-sen University from January 2006 to December 2011 were enrolled.The clinicopathological features and renal outcomes of patients with and without chronic tonsillitis were retrospectively compared.The primary outcome was progression to end stage renal diseases and/or doubling of serum creatinine.Results A total of 981 primary IgAN patients were enrolled and 98 patients (9.99％) had a history of chronic tonsillitis.Compared with patients without chronic tonsillitis,IgAN patients with chronic tonsillitis exhibited significantly higher prevalence of acute episodes of tonsillitis as a predisposition (P ＜ 0.001),higher serum IgA levels (P=0.012),and higher prevalence of macrohematuria (P=0.006).No significant difference in renal pathological features was observed in patients with and without chronic tonsillitis.Moreover,the renal outcomes were similar as regards IgAN patients with and without chronic tonsillitis.Conclusion IgAN patients with chronic tonsillitis had higher prevalence of acute episodes of tonsillitis and macrohematuria as well as higher serum IgA levels.However,IgAN patients with and without chronic tonsillitis showed no significant difference in renal pathological features and renal outcomes.
