Objective To analyze the disease burden of lung cancer attributable to air pollution among the Chinese population from 1990 to 2021,providing a scientific basis for the prevention and control strategies of lung cancer.Methods Data on deaths,mortality rates,disability-adjusted life years(DALY)of lung cancer,and world population data attributable to air pollution in China from 1990 to 2021 were extracted from the global burden of disease study 2021(GBD 2021).The Joinpoint regression model was used to calculate the annual percentage change(APC)and average annual percentage change(AAPC)for analysis of disease burden.The age-period-cohort model was employed to investigate the effects of age,period,and cohort on the trends in lung cancer disease burden attributable to air pollution.Results The population attributable fraction(PAF)of lung cancer in China due to air pollution has shown a trend of decrease,with an average AAPC value of-1.16%(P<0.001).The numbers of death and DALYs generally increased by years,with an AAPC value of 2.14%and 1.54%,respectively(both P<0.001).However,the standardized mortality rate and standardized DALY rate initially increased and then decreased,with an AAPC value of 0.34%and-0.14%,respectively,showing no statistical significance.The mortality rate,standardized mortality rate,DALY rate,and standardized DALY rate of lung cancer attributable to air pollution were higher in males than in females.Age-period-cohort model analysis showed that the net drifts of lung cancer mortality rates attributable to air pollution for the overall population,males,and females were-1.52%,-1.33%,and-1.88%,respectively(all P<0.001).The death risk increased with age.There are higher mortality rates in males across all age groups compared to females,especially in the population over 50 years.The period effect showed a U-shape trend from 1990 to 2004,and a decreasing trend after 2005.There was a decreasing trend of death risk with the progression of birth cohorts.Conclusion From 1990 to 2021,the relative contribution of air pollution to lung cancer in China has gradually decreased,and the risk of lung cancer death attributable to air pollution has generally shown a downward trend.The risk is higher in males than in females,higher in elderly population,and lower with the progression of birth cohorts.Increased attention should be paid to high-risk groups such as males and the elderly population,and early screening and intervention for the disease should be strengthened to reduce the risk of lung cancer.

Objective:To analyze Chinese and English literature related to Kangfuxin liquid for wound healing using CiteSpace Knowledge Graph,and to understand its research hotspots,current status,and development trend.Methods:Chinese literature on Kangfuxin Liquid in promoting wound healing was retrieved from the China National Knowledge Infrastructure(CNKI),and English literature from Web of Science(WOS),covering the period from January 1,2004,to October 1,2024.CiteSpace 6.1.R6 was used to perform visual analyses based on publication volume,institutions,authors,and keywords.Results:A total of 795 Chinese articles and 21 English articles were included.Overall publication volumes for both languages showed an upward trend,though Chinese publications slightly declined after 2017.Author collaboration network analysis revealed scattered and limited cooperation among researchers,with the field predominantly led by domestic scholars.Institutional collaboration analysis identified Chengdu University of Traditional Chinese Medicine as the most prolific institution in both Chinese and English literature.The mapping indicated closer collaboration among English literature institutions compared to Chinese counterparts.High-frequency keywords in Chinese literature included Kangfuxin liquid,pressure ulcer,and wound healing,while English keywords included expression,chitosan,and induced gastric ulcer.The representative clustering tags in the Chinese database were#0 Kangfuxin,#1 nurse,and#2 therapeutic effect.The representative English clustering tags were#0 diabetic wound,#1 marine polysaccharide,and#2 slamf 9.The research hotspot of the Chinese database before 2019 focused on Kangfuxin Liquid's role in wound healing,while post-2020 studies shifted toward the role of inflammatory factors during healing.Conclusions:Visual analysis confirms Kangfuxin Liquid in wound healing as a research hotspot.Future studies should strengthen interdisciplinary and regional collaborations,with mechanistic exploration and clinical applications prioritized.

Objective To select the appropriate batch length and quality control procedure for the blood cell analysis project of the Women and Children's Hospital of Leshan with an online calculation tool of internal quality control frequency,and explored the measurement frequency of blood cell analysis laboratory quality control. Methods The coefficient of variation of blood cell analysis internal quality control of the Women and Children's Hospital of Leshan from April to December 2023 was collected as the imprecision of the project.The results of the laboratory participating in the 2023 National Health Commission inter-laboratory quality evaluation blood count experiment were used to evaluate the bias of each item.

Objective:To investigate the clinicopathological features and genetic mutation status of pulmonary intravascular large B cell lymphoma.Methods:The clinicopathological data of eight patients diagnosed with pulmonary intravascular large B cell lymphoma, from April 2018 to May 2023, were retrospectively analyzed. The genetic profile of six patients was detected via next-generation sequencing (NGS) and followed up.Results:All patients included one male and seven females, with a median age of 64 years (ranging from 45 to 66 years). Respiratory symptoms were the most common (7 cases), B symptoms in two cases, hemophagocytic syndrome in two cases. Multiple diffuse ground-glass opacities in both lungs were observed based on the high-resolution chest CT scan. Six cases of mild to moderate ventilation or diffusion dysfunction were observed based on the pulmonary function tests. Moreover, two cases of hypoxemia and two cases with type Ⅰ respiratory failure were recorded. The serum lactate dehydrogenase level increased (7/8), β2-MG level increased (2/8), neuron-specific enolase level increased (7/8), total number of peripheral blood lymphocytes decreased (7/8), and clinical stages were all stage Ⅳ. The neoplastic lymphoid cells were lodged in the lumina of venules and capillaries of the alveolar septum; the tumor cells were large, with prominent nucleoli and frequent mitotic figures. The malignant cells were detected in the extravascular surrounding lung tissue in all cases. The tumor cells expressed mature B cell-associated antigens CD20 and CD79a, and the vascular endothelial markers CD31 and CD34 showed that the tumor cells were filled in the blood vessels, infiltrated blood vessel walls, and perivascular areas. One case was germinal center-type, seven cases were non-germinal center-type, two cases were double-expressing lymphoma, and all cases were EBER-negative. Furthermore, the top five genes with mutation frequencies detected by NGS were MYD88 (5/6), PIM1 (5/6), CD79B (4/6), TCF3 (4/6), and TP53 (3/6). Of the eight cases, seven patients received R-CHOP-based chemotherapy, six cases had complete remission after chemotherapy, one case died, and one case was lost to follow-up.Conclusions:Pulmonary vascular large B cell lymphoma is rare, which shares similar patterns with interstitial lung disease on imaging. Transbronchial lung biopsy is an effective method to confirm the diagnosis. Immunochemotherapy with BTK inhibitors can provide a survival advantage for patients in the future based on molecular typing.

The neural stimulator is a core component of animal robots. While the control effect of animal robots is influenced by various factors, the performance of the neural stimulator plays a decisive role in regulating animal robots. In order to optimize animal robots, embedded neural stimulators had been developed using flexible printed circuit board technology. This innovation not only enabled the stimulator to generate parameter-adjustable biphasic current pulses through control signals, but also optimized its carrying mode, material, and size, overcoming the disadvantages of traditional backpack or head-inserted stimulators, which have poor concealment and are prone to infection. Static, in vitro, and in vivo performance tests of the stimulator demonstrated that it not only had precise pulse waveform output capability, but also was lightweight and small in size. It had excellent in vivo performance in both laboratory and outdoor environments. Our study has high practical significance for the application of animal robots.
