Heterogeneous organ-specific responses to immunotherapy exist in lung cancer. Dissecting tumor microenvironment (TME) can provide new insights into the mechanisms of divergent responses, the process of which remains poor, partly due to the challenges associated with single-cell profiling using formalin-fixed paraffin-embedded (FFPE) materials. In this study, single-cell nuclei RNA sequencing and imaging mass cytometry (IMC) are used to dissect organ-specific cellular and spatial TME based on FFPE samples from paired primary lung adenocarcinoma (LUAD) and metastases.

However, few studies explore the impact of APOE macrophages on ICI therapy using single-cell RNA sequencing (scRNA-seq) and machine learning methods. The scRNA-seq and bulk RNA-seq data are Integrated to construct an M.

This study aimed to evaluate the surrogacy of progression-free survival (PFS) and one-year (1-yr) milestone survival for OS in HCC trials.
Methods: We systematically searched databases for randomized clinical trials that evaluated systemic treatments for advanced HCC.
Colorectal cancer (CRC) is a common malignancy involving multiple cellular components. The CRC tumor microenvironment (TME) has been characterized well at single-cell resolution. However, a spatial interaction map of the CRC TME is still elusive.

We conducted a study that combined proteomics and mutation data of CRM from a cohort of three centers over a 16-years period (2005-2021). The patients were divided into a training set consisting of two centers and a testing set comprising the other center.

TME heterogeneity makes the response to immunotherapy different in different tumors, such as "immune-cold" and "immune-hot" tumors. Tumor-associated macrophages, myeloid-derived suppressor cells, and regulatory T cells are the major suppressive immune cells and their different phenotypes interact and influence cancer cells by secreting different signaling factors, thus playing a key role in the formation of the TME as well as in the initiation, growth, and metastasis of cancer cells.

However, the efficacy in tumors with low immunogenicity requires further investigation. In this work, a water-in-oil Pickering emulsion gel is developed to deliver (1S, 3R)-RSL-3 (RSL-3), a ferroptosis inducer dissolved in iodized oil, and programmed death-1 (PD-1) antibody, the most commonly used immune checkpoint inhibitor dissolved in water, with optimal characteristics (RSL-3 + PD-1@gel).

Here we build a unified theoretical framework to describe BC's mixing states, linking dynamic processes to BC coating thickness distribution, and show its self-similarity for sites in diverse environments. The size distribution of BC-containing particles is found to follow a universal law and is independent of BC core size.

The present study aims to investigate the association between KMT2D exon 39 mutation (K-ex39) and molecular and clinical characteristics in colorectal adenocarcinoma (CRAD).
Methods: We performed profiling of KMT2D and K-ex39 via Kaplan-Meier analysis, cBioportal, Immune-related functional analysis and correlation analysis with TCGA and MSK cohorts to explore their effects on the prognosis, immune landscape, molecular characteristics and drug sensitivity in CRAD.
Airborne aerosols reduce surface solar radiation through light scattering and absorption (aerosol direct effects, ADEs), influence regional meteorology, and further affect atmospheric chemical reactions and aerosol concentrations. The inhibition of turbulence and the strengthened atmospheric stability induced by ADEs increases surface primary aerosol concentration, but the pathway of ADE impacts on secondary aerosol is still unclear. In this study, the online coupled meteorological and chemistry model (WRF-CMAQ; Weather Research and Forecasting-Community Multiscale Air Quality) with integrated process analysis was applied to explore how ADEs affect secondary aerosol formation through changes in atmospheric dynamics and photolysis processes.

Objective: This study explored the effects of urinary kallidinogenase (UK) on ischemia and necrosis of random skin flaps in rats, and the mechanisms thereof.
Methodology: Ischemia and necrosis of random skin flaps were induced by constructing a modified McFarlane flap model on the dorsa of rats. UK (0.
Objective: Batroxobin is a medicinal preparation extracted from the venom of the Fer-de-Lance snake, and is used to lower blood viscosity, promote blood fibrinogen decomposition, and inhibit thrombosis. This research is to investigate whether batroxobin can improve the survival of random skin flaps in a rat model.
Materials And Methods: Dorsal McFarlane flaps were harvested from 36 rats divided into two groups.

Senna is one of the commonly used traditional Chinese medicine at present. After the preliminary research that the drug medication history in China is not long, in our country ancient times, only "Hui prescription" in the records, other all kinds of traditional Chinese medicine literature rarely mentioned. Since modern times, the Chinese medicine in the medicine in the literature of the time and the modern western medicine books in the Chinese version of the time generally close, may be related to the introduction of Western medicine.

Through the research of the teaching material of TCM basic theory since the establishment of the People's Republic of China, it can be considered that there are 3 stages for the construction of the theory of "liver controlling conveyance and dispersion". From the 1950s to 1970s, this theory was not mentioned in any teaching materials; from the 1970s to the mid 1980s, different views about this theory can be seen in the teaching materials; after the mid 1980s, this theory in the teaching materials became gradually basically identical.
