Excel summarized the data, and the mortality rate, DALYs and age-normalized rate were analyzed. Applying Joinpoint Regression Program software annual Percentage Change (APC) and Average Annual Percentage Change Rate (AAPC) .Results:Age-standardized mortality rates ranged from 2.41 in 1990 to 3.14 per 100 000 in 2019, with gender differences and a positive correlation with age. DALYs increased from 580, 000 person-years in 1990 to 1 509 900 person-years in 2019. The rate of standardized DALYs increased from 63.03 per 100 000 in 1990 to 71.65 per 100 000 in 2019. According to the annual percentage change (APC) analysis by Joinpoint Regression Program software, the age-normalized mortality and DALY rates decreased from 2011 to 2016, and the increasing trend from 2016 to 2019 was significantly lower than that before 2011. And the increase at this stage was not statistically significant. The APCC values of mortality rate, standardized mortality rate, DALYs rate and changed DALYs rate were 3.28, 0.92, 2.64 and 0.44, respectively, and the trend differences were statistically significant.Conclusion:The disease burden of occupational lung cancer is increasing from 1990 to 2019. Lung cancer screening should be carried out among high-risk populations to achieve early diagnosis and treatment.

Objective To investigate the mechanism of Guizhi Tongluo Tablets(GZTLP)on improving atherosclerosis in APOE knockout mice by regulating neutrophil extracellular trapping nets(NETs).Methods After modeling,24 APOE knockout mice aged 8 weeks were randomly divided into 4 groups:GZTLP high-dose group,low-dose group,model control group and normal control group,with 6 mice in each group.GZTLP was given 1.87 mg·g-1 and 0.47 mg·g-1 intragastric administration in high-dose group and low-dose group,respectively.The normal control group and model control group were given 0.9%sodium chloride solution intragastric administration for 6 weeks,and the lipid plaque deposition in aorta was observed by gross oil red O staining.Lipid deposition in aortic root was observed by oil red O staining.The pathological changes of lipid plaques in aortic root were observed by HE staining.The levels of interleukin-1β(IL-1β)and tumor necrosis factor α(TNF-α)in peripheral blood of mice were detected by enzyme-linked immunosorbent assay(ELISA).The expression of lymphocyte antigen 6G(Ly6G),myeloperoxidase(MPO)and citrulinated histone(Cit-H3)in plaques of the aortic arch and the colocalization of Ly6G,MPO and Cit-H3 were detected by immunofluorescence assay.Results Compared with the normal control group,the aorta of mice in the model control group showed serious lipid plaque deposition,morphological damage,and a large number of inflammatory cells infiltration,the contents of serum inflammatory factors IL-1β and TNF-α were increased,and the protein expressions of Ly6G,Cit-H3 and MPO were significantly increased.Compared with model control group,GZTLP group reduced the amount of lipid plaque deposition in aorta,the arrangement of aortic cells was more regular,the inflammatory cell infiltration was improved,and the contents of serum inflammatory factors IL-1β and TNF-α were significantly decreased(P<0.05).The colocalization and the protein expression of Ly6G,MPO and Cit-H3 were significantly decreased in aortic tissues(P<0.01).Conclusions GZTLP can improve atherosclerosis,and its mechanism may be related to the inhibition of neutrophil extracellular trapping nets.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

The loss of endothelial connective integrity and endothelial barrier dysfunction can lead to increased vascular injury, which is related to the activation of endothelial inflammasomes. There are evidences that low concentrations of aspirin can effectively prevent cardiovascular diseases. We hypothesized that low-dose aspirin could ameliorate endothelial injury by inhibiting the activation of NLRP3 inflammasomes and ultimately prevent cardiovascular diseases. Microvascular endothelial cells were stimulated by lipopolysaccharide (2 μg/mL) and administrated by 0.1-2 mmol/L aspirin. The wild type mice were stimulated with LPS (100 μg/kg/day), and 1 h later treated with aspirin (12.5, 62.5, or 125 mg/kg/day) and dexamethasone (0.0182 mg/kg/day) for 7 days. Plasma and heart were harvested for measurement of ELISA and immunofluorescence analyses. We found that aspirin could inhibit NLRP3 inflammasome formation and activation in dose-dependent manner and has correlation between the NLRP3 inflammasome and the ROS/TXNIP pathway. We also found that low-concentration aspirin could inhibit the formation and activation of NLRP3 inflammasome and restore the expression of the endothelial tight junction protein zonula occludens-1/2 (ZO1/2). We assume that aspirin can ameliorate the endothelial layer dysfunction by suppressing the activation of NLRP3 inflammasome.

Objective To observe the clinical efficacy and safety of etoposide capsule (VP16) in the treatment of recurrent small cell lung cancer. Methods Retrospective analysis 39 patients,aged≥65, with relapsed small cell lung cancer, who were at least three months after the end of the first-line treatment since January 2012 to January 2014 in Tianjin fifth central hospital.Etoposide was administered by daily oral at 100 mg/day for seven consecutive days and withdraw for 14 days,21 days as a therapeutic cycle,repeat treatment until disease progression or intolerable side effects occur, analyze the progression-free survival and overall survival.Observe the clinical benefit rate,the overall response rate and safety.Results The clinical benefit rate (DCR) and overall response rate (ORR) after the treatment were 61.5% and 30.77%.The progression-free survival (PFS) was 2.8 months, and the overall survival (OS) was 7.3 months.Neutropenia is the most common toxicities, and grade Ⅲ or Ⅳ occurred in 7.7% of the patients.No grade Ⅲ or Ⅳ thrombocytopenia, or grade Ⅲ or Ⅳ non-hematologic toxicity was occured.Conclusion Etoposide oral capsules monotherapy may be considered as one of the safe and effective choice of the second-line treatment of elderly patients with relapsed small cell lung cancer.

Objective To evaluate the diagnosis of frozen shoulder with the coracohumeral ligament on the coronal oblique plane with MRI.Methods There were 60 patients(120 shoulder joints)in control group,with 30 males and 30 females,the mean age was 50.5 years old.There were 72 shoulder joints in 72 patients of frozen shoulder group(50 femles and 22 males with a mean age of 53.5 years)with clini-cal evidence and MR imaging evidence of frozen shoulder.These were prospectively analyzed to identify the CHL visualization rate and meas-ure the maximum thickness of the CHL.Results The CHL visualization rate on the coronal oblique plane in the control group was 86.7%(104 /120),and the frozen shoulder group was 87.5%(63 /72),the difference was not significant(P >0.05).The CHL visualization rate on the axial view in the frozen shoulder group was 19.4%(14 /72)and the control group was 24.2%(29 /120),the difference was not signifi-cant(P >0.05).The CHL thickness on the coronal oblique plane (n =63)in the patients with frozen shoulder was (4.37 ±1.71)mm, which was significantly greater than (2.84 ±0.79)mm ofpatients in the control group(n =104),the difference was significant(P <0.001). The CHL thickness on the axial plane(n =14)in the patients with frozen shoulder was (3.93 ±1.49)mm,which was significantly greater than (2.29 ±0.65)mm of patients in the control group(n =29),the difference was significant(P <0.001).Conclusion A thickened CHL is highly suggestive of frozen shoulder,which is 4.37 mm on the coronal oblique plane.

Objective To investigate the expression level and clinical significance of serum IL-18 and MCP-1 in patients with Chronic Obstructive Pulmonary Disease(COPD).Methods Serum IL-18 and MCP-1 levels were measured in healthy people( control group,30 cases) and in patients with COPD (acute stage group and stable stage group,30 cases in each group).At the same time,the level of serum CRP and forced expiratory volume in one second ( FEV1 ),the forced expiratory volume in one second/forced vital capacity ( FEV1/FVC％ ) were tested in the three groups.The variation.of the level of serum IL-18 and MCP-1 and the correlation between these index with lung function and CRP were analyzed.Results The levels of serum IL-18 and MCP-1 in acute stage group ( IL-18 [ 69.29 ± 16.14 ] ng/L,MCP-1 [ 123.95 ± 32.06 ] ng/L) were significantly higher than those in stable stage group ( IL-18 [ 53.15 ± 14.74 ] ng/L,MCP-1 [ 96.46 ± 18.24 ] ng/L) ( F =10.975,P ＜0.01 ),and also significantly higher than those in control group ( IL-18 [ 37.53 ± 14.55 ] ng/L,MCP-1 [60.86 ± 17.26] ng/L) ( F =18.101,P ＜ 0.01 ).In acute stage group,positive correlations were obtained among the level of serum IL-18,MCP-1 and CRP ( r =0.688,P ＜ 0.05 ; r =0.663,P ＜ 0.05 ; r =0.825,P ＜0.01 ),and they were correlated negatively with FEV1 and FEV1/FVC％ ( r =- 0.732,P ＜ 0.01 ;r =- 0.586,P ＜0.05 ).In stable stage group,the level of serum MCP-1 was correlated positively with the level of IL-18( r =0.674,P ＜ 0.05 ) and with the level of CRP ( r =0.719,P ＜ 0.05 ),but it was correlated negatively with FEV1 and FEV1/FVC％ ( r =-0.512,P ＜ 0.05 ;r =-0.557,P ＜ 0.05 ).Conclusion The serum IL-18 and MCP-1may be one of the inflammation markers in patients with COPD and may be associated with airway inflammation and limited airflow.
