Sepsis is a systemic inflammatory response caused by severe infection or trauma, and is one of the common causes of acute lung injury(ALI) and acute respiratory distress syndrome(ARDS). Sepsis-acute lung injury(SALI) is a critical clinical condition with high morbidity and mortality. Its pathogenesis is complex and not yet fully understood, and there is currently a lack of targeted and effective treatment options. Pyroptosis, a novel form of programmed cell death, plays a key role in the pathological process of SALI by activating inflammasomes and releasing inflammatory factors, making it a potential therapeutic target. In recent years, the role of traditional Chinese medicine(TCM) in regulating signaling pathways related to pyroptosis through multi-components and multi-targets has attracted increasing attention. TCM may intervene in pyroptosis by inhibiting the activation of NLRP3 inflammasomes and regulating the expression of Caspase family proteins, thus alleviating inflammatory damage in lung tissues. This paper systematically reviews the molecular regulatory network of pyroptosis in SALI and explores the potential mechanisms and research progress on TCM intervention in cellular pyroptosis. The aim is to provide new ideas and theoretical support for basic research and clinical treatment strategies of TCM in SALI.

Objective:To investigate the changes of the epidemiology and clinical characteristics of human metapneumovirus (hMPV) among children with acute lower respiratory tract infection (ALRTI) before and after the discontinuation of non-pharmaceutical interventions (NPI) during coronavirus disease 2019 epidemic.Methods:This was a retrospective cohort study. Children hospitalized at The Second Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University between January 2021 and December 2023, who were diagnosed with ALRTI by nasopharyngeal secretion testing for respiratory pathogens nucleic acid were enrolled. Clinical and laboratory data were collected. Children admitted between January 1, 2021 and January 7, 2023 were classified as the pre-NPI withdrawal group (abbreviated as pre-withdrawal group), while those admitted from January 8, 2023 afterward were classified as the post-NPI withdrawal group (abbreviated as post-withdrawal group). Nasopharyngeal secretions from the enrolled children were tested for 13 respiratory pathogens using polymerase chain reaction-capillary electrophoresis fragment analysis, and bacterial cultures were also performed. Statistical analyses were performed using the Mann-Whitney U test or chi-square test. Results:A total of 30 855 ALRTI cases were enrolled, with 1 679 of hMPV-positive. In the pre-withdrawal group, there were 861 cases with an age of onset of 2.0(1.0, 3.0) years, and the highest proportion was in the 1 to <3 years age group, accounting for 35.3%(304/861). In the post-withdrawal group, there were 818 cases with an age of onset of 3.0(2.0, 4.0) years, and the highest proportion was in the 3 to <5 years age group, accounting for 39.2%(321/818).The age of onset in the post-withdrawal group was significantly older than that in the pre-withdrawal group ( Z=7.69, P<0.001) .The hMPV detection rate was higher in the pre-withdrawal group than that in post-withdrawal group (5.75%(861/14 984) vs 5.15%(818/15 871); χ2=5.25, P=0.022). In the pre-withdrawal group, the epidemic peaks occurred in winter and spring, with the highest rates in January 2022(25.2%(224/890)) and March 2022 (21.6%(186/860)). In the post-withdrawal group, the epidemic peak shifted to spring and summer, and the detection rate became increased since April 2023(10.8%(136/1 258)). The post-withdrawal group showed lower rates of wheezing, shortness of breath, cyanosis, respiratory support, severe pneumonia, intensive care unit admission, and shorter hospital stays compared to the pre-withdrawal group ( χ2=69.09, 31.63, 12.97, 57.96, 55.73, 5.48 and Z=7.11, respectively, all P< 0.05).In the pre-withdrawal group, 412 cases (47.9%(412/861)) had other pathogens detected, compared to 445 cases (54.4%(445/181)) in the post-withdrawal group, indicating a significantly higher rate of co-infections in the post-withdrawal group ( χ2=7.20, P<0.05). The most commonly detected pathogens in both groups were Mycoplasma pneumoniae (MP), rhinovirus, and Streptococcus pneumoniae. However, the post-withdrawal group showed significantly higher detection rates of MP and influenza virus, but lower bacterial detection rates compared to the pre-withdrawal group ( χ2=39.41, 9.70, 5.63, respectively, all P<0.05). The detection rate of Haemophilus influenzae was 2.1%(17/818) in the post-withdrawal group which lower than that (6.7%(58/861)) in the pre-withdrawal group, and the difference was statistically significant ( χ2=21.32, P<0.001). Conclusions:In 2023, following the withdrawal of NPI, the epidemic peak of hMPV in Wenzhou area is delayed to spring and summer. The age of children with hMPV-associated ALRTI increases, with the majority being 3 to <5 years old. The overall severity of the disease decreases. However, the detection of mixed pathogens increases, with MP being the most common, while bacterial detection decreases.

In recent years, the traditional Chinese medicine(TCM)industry has experienced rapid development, resulting in a significant amount of Chinese medicinal residues generated during the industrial manufacturing process. Currently, the main methods of handling Chinese medicinal residues include stacking, landfilling, and incineration, which lead to substantial resource waste and potential environmental pollution. With "carbon peak" and "carbon neutrality"( "Dual Carbon")becoming national strategic goals, the TCM industry is ushering in a new wave of "low-carbon" trends, and the high-value utilization of Chinese medicinal residues has become a breakthrough for implementing a low-carbon economy in the TCM sector. From the perspective of a low-carbon economy, this article reviewed literature in China and abroad to summarize the microbial transformation technology, enzymatic conversion technology, biomass pyrolysis, gasification, hydrothermal liquefaction, and other high-value utilization technologies for Chinese medicinal residues. It also overviewed the applications of Chinese medicinal residue in feed additives, organic fertilizers, edible mushroom cultivation substrates, preparation of activated carbon for wastewater treatment, and new energy batteries. Considering the current status of resource utilization of Chinese medicinal residues, feasible strategies and suggestions for resource development and utilization were proposed to improve the quality and efficiency of the Chinese medicinal resource industry chain and promote green development, thereby providing research ideas and theoretical basis for achieving carbon peak and carbon neutrality goals.

Traditional Chinese medicine market is a typical market with information asymmetry, which may lead to "lemons" problem. Third-Party Certification is efficient path to solve the problem of information asymmetry. For this reason geo-authentic and commodity classes certification seems to be very important. But as we know, information asymmetry happen in the stages of traditional Chinese patent medicines market. So a signaling transfer mechanism, which can deliver the quality signal, is badly needed in TCM market. This paper analysis and design of signaling transfer mechanism based on Third-Party Certification, which called quality prestige index of TCM enterprises (QPITCM). QPITCM can display quality information as a signal run through the TCM market.

A dispute about the decreasing-price problem of traditional Chinese medicine (TCM) has recently arisen. This article analyzes the statistical data of 1995-2011 in China, the results showed that the main responsibility of expensive health care has no direct relationship with the drug price. The price index of TCM rose significantly slower than the medicine prices, the production margins of TCM affected by the material prices has been diminishing since 1995, continuous price reduction will further depress profits of the TCM industry. Considering the pros and cons of raw materials vary greatly in price, decreasing medicine price behavior will force enterprises to use inferior materials in order to maintain corporate profits. The results have the guiding meaning to medicine price management.
