Most immune-related adverse event (irAE) associated with immune checkpoint inhibitors (ICIs) resulted from excessive immune response against normal organs. The severity, timing, and organs affected by these events were often unpredictable. Adverse reactions could cause treatment delays or interruptions, in rare cases, pose a life-threatening risk. The mechanisms underlying irAE involved immune cell dysregulation, imbalances in inflammatory factor expression, alterations in autoantibodies and complement activation, even dysbiosis of intestinal microorganisms. However, the mechanisms of irAE occurrence might differ slightly among organs due to variations in their structures and the functions of resident immune cells. Future research should focus on the development of targeted drugs for the prevention or treatment of irAE based on the mechanisms by which irAE occurs in different organs. A deeper understanding of the mechanisms underlying irAE occurrence would aid clinicians in effectively utilizing ICIs and provide valuable guidance for their clinical application.
Objective To investigate the expression of aquaporin-1（AQP-1） on pleura in rats with carrageenan-induced pleural effusion and explore the role of AQP-1 in effusion formation.Methods Fifty-six healthy Wistar rats were randomly divided into a normal control group and 6 pleuritis groups（6，12，24，36，48 and 72 h groups respectively）.The rat model of inflammatory pleurisy was induced by injecting l-Carrageenan into the pleural cavity.The expression of AQP-1 on pleura was detected with immunohistochemistry.The mRNA and protein expression of AQP-1 on visceral pleura and parietal pleura were measured by RT-PCR and Western blot assay respectively.The volume of pleural effusions were measured.Results The volume of pleural effusion was 2.10±0.22，4.10±0.15，4.40±0.36，3.20±0.27，2.60±0.18，0.12±0.02 mL in the 6，12，24，36，48 and 72 h pleuritis groups respectively.AQP-1 were mainly expressed on visceral and parietal pleural mesothelial cells and capillary endothelial cells，and significantly increased in all pleuritic rats The mRNA and protein expression of AQP-1 on parietal pleura increased after 6 h and reached peak level at 24 h in pleuritic groups.The mRNA and protein expression of AQP-1 on visceral pleura increased after 12 h and reached peak level at 24 h in pleuritic groups.The expression of AQP-1 on parietal pleura at 12 h and 24 h in pleuritic groups was correlated positively with the volume of pleural effusion（r=0.857，r=0.846，all Plt;0.01）.The expression of AQP-1 on visceral pleura at 24 h in pleuritic groups was positively correlated with the volume of pleural effusion（r=0.725，Plt;0.05）.Conclusion The expression of AQP-1 on pleura were increased in rats with e carrageenan-induced pleural effusion.AQP-1 may play a role in pleural fluid transportation in pleural effusion.

Extrinsic allergic alveolitis is a general term for type Ⅲ or Ⅳ allergic pneumonia caused by repeated inhalation of various antigenic organic dusts and low molecular weight chemicals in susceptible people. The lesions involve alveolar, pulmonary interstitial, and airway. The main clinical manifestations are cough, expectoration, and dyspnea. Clinically, extrinsic allergic alveolitis is classified into acute, subacute, and chronic forms. Extrinsic allergic alveolitis has a great impact on the pulmonary function of patients. Timely treatment will improve clinical symptoms and inhibit the development of disease. The current treatment plan is mainly avoiding exposure to antigen, glucocorticoid therapy, immunosuppressive therapy, anti-fibrotic therapy, and lung transplantation.
ObjectiveTo analyze the changing trend of cancer burden in China from 2005 to 2020, so as to provide reference for the formulation of cancer prevention and control strategies. MethodBased on the report “National and subnational trends in cancer burden in China, 2005–20”, the overall changes in cancer deaths in China by gender, age, urban and rural areas, and different regions of the country were analyzed. Results① Among the whole population, the number of cancer-related deaths and years of life lost (YLLs) in China increased by 21.6% and 5.0% respectively, and the top third leading cause of cancer-related deaths ranked by mortality rate were tracheal, bronchus, and lung cancer, liver cancer, and stomach cancer. ② In different gender groups, for the males, the top five leading cause of cancer-related deaths by mortality rate remained unchanged from 2005 to 2020, they were tracheal, bronchus, and lung cancer, liver cancer, stomach cancer, oesophageal cancer, and colon and rectum cancer. The average annual percent change (AAPC) of the age-standardized mortality rate (ASMR) increased in 4 of the leading 10 cancers, followed by prostate cancer (1.70 per 100 000), pancreatic cancer (0.95 per 100 000), lymphoma (0.33 per 100 000), and colon and rectum cancer (0.31 per 100 000). For the females, the tracheal, bronchus, and lung cancer remained the first leading cancer from 2005 to 2020, the second to the fifth leading cancers by mortality rate showed evident changes, with the liver cancer moving from the third to the second position, the stomach cancer moving from the second to the third position, the colon and rectum cancers moving from the fifth to the fourth position, and the breast cancer moving from the sixth to the fifth position, the pancreatic cancer moving from the ninth to the eighth position. Among the top 10 cancers, only the pancreatic cancer had an increase in AAPC of ASMR (0.67 per 100 000). ③ Among different age groups, the cancer-related mortality in young people (18–44 years old) and middle-aged people (45–59 years old) was much lower than that of the elderly (over 60 years old). ④ The mortality and YLL rates due to cancer in rural areas were higher than those in urban areas for both sexes. The cancer mortality rates of 11 provinces or regions such as Anhui were higher than those the national average value. The mortality, ASMR, YLL rates, and age-standardized YLL rates of all cancer types in Guangxi Zhuang Autonomous Region, Hebei, Xinjiang Uygur Autonomous Region, Henan, and Qinghai decreased in the males and which in Jiangsu, Henan, Guangxi Zhuang Autonomous Region, Xinjiang Uygur Autonomous Region, and Shanghai in the females also decreased. The ASMR of the colon and rectum cancer and pancreatic cancer increased significantly in some provinces or regions.ConclusionsFrom 2005 to 2020, there are rising trends in the number of cancer-related deaths and YLLs in China, and there are differences in the gender, age, urban and rural, and regional distribution of cancer burden. The prevention and control situation is grim, there is an urgent need for a comprehensive cancer prevention and control strategy to deal with the changing cancer burden in China.
ObjectiveTo provide policy suggestions concerning the distribution of health resources between urban and rural areas and management and education of diabetes, this study depicted the current status of access to healthcare and analyzed its determinants among Chinese diabetic patients.MethodsMultivariate ordinal logistic regression and multivariate binary logistic regression were employed to analyze the effects of socioeconomic status and urban-rural disparities on health access.ResultsMultivariate results suggested that urban patients were more likely to conduct more blood glucose tests (P<0.000 1) and receive more self-care suggestions from physicians (P=0.02). After controlling all other covariates, patients graduated from secondary schools and those with vocational school degrees or above were 1.61 and 2.44 times more possible to take more blood glucose tests.Conclusions There exists significant urban-rural disparities of access to healthcare among Chinese diabetic patients. Education may be a key factor of access to healthcare among Chinese diabetic patients. It’s highly recommended to implement education programs on diabetes management in rural areas, where the education status and demographic factors should be considered. The distribution of health resource in rural areas requires more policy and governmental support.
