BACKGROUND: Double-stranded RNA-specific adenosine deaminase 1 (ADAR1) binds to double-stranded RNA and catalyzes the deamination of adenosine (A) to inosine (I). The functional mechanism of ADAR1 in non-small cell lung cancer (NSCLC) remains incompletely understood. This study aimed to investigate the prognostic significance of ADAR1 in NSCLC and to elucidate its potential role in regulating tumor cell proliferation and migration. METHODS: Data from The Cancer Genome Atlas (TCGA) and cBioPortal were analyzed to assess the correlation between high ADAR1 expression and clinicopathological features as well as prognosis in lung cancer. We performed Western blot (WB), cell proliferation assays, Transwell invasion/migration assays, and nude mouse xenograft modeling to examine the phenotypic changes and molecular mechanisms induced by ADAR1 knockdown. Furthermore, the ADAR1 p150 overexpression model was utilized to validate the proposed mechanism. RESULTS: ADAR1 expression was significantly elevated in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) tissues compared with adjacent non-tumor tissues (LUAD: P=3.70×10-15, LUSC: P=0.016). High ADAR1 expression was associated with poor prognosis (LUAD: P=2.03×10-2, LUSC: P=2.81×10-2) and distant metastasis (P=0.003). Gene Set Enrichment Analysis (GSEA) indicated that elevated ADAR1 was associated with mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathway activation, matrix metalloproteinase-9 (MMP-9) expression, and cell adhesion. ADAR1 and MMP-9 levels showed a strongly positive correlation (P=6.45×10-34) in 10 lung cancer cell lines, highest in H1581. Knockdown of ADAR1 in H1581 cells induced a rounded cellular morphology with reduced pseudopodia. Concomitantly, it suppressed cell proliferation, invasion, migration, and in vivo tumorigenesis. It also suppressed ERK phosphorylation and downregulated cellular Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog (c-FOS), MMP-9, N-cadherin, and Vimentin. Conversely, ADAR1 p150 overexpression in PC9 cells enhanced ERK phosphorylation and increased c-FOS and MMP-9 expression. CONCLUSIONS High ADAR1 expression is closely associated with poor prognosis and distant metastasis in NSCLC patients. Mechanistically, ADAR1 may promote proliferation, invasion, migration, and tumorigenesis in lung cancer cells via the ERK/c-FOS/MMP-9 axis.

This paper explores the therapeutic approach for glaucoma based on the concept of "jueyin （厥阴） as the closing phase" from the perspectives of time and space. In traditional Chinese medicine， jueyin governs inward， converging aspect of qi， representing the crucial turning point between the end of yin and the emergence of yang， as well as the transformation between yin and yang. When the closing and descending function of jueyin operates smoothly， it promotes the inward convergence and smooth descent of qi， enabling the internal retention of blood， spirit， and emotions， which nourishes the internal organs and moistens the meridian-sinews. Conversely， dysfunction of this "closing" mechanism results in a disturbance of yin and yang， a mixture of cold and heat， and disharmony of qi and blood. It is proposed that "failure of jueyin to properly close and descend" is a core pathomechanism of glaucoma. From the perspective of spatiotemporal theory， clinical treatment should focus on "regulating the closing function of jueyin and harmonizing yin and yang". The modified Wumei Pill （乌梅丸） is recommended to adjust the ascending-descending and entering-exiting dynamics of jueyin qi transformation， thereby restoring its free flow， achieving yin and yang balance， and ensuring nourishment to the ocular system.

The theory of “rhythmic equilibrium” is developed based on the idea of sharing the same laws between nature and human， and by integrating with the medical concept of homeostasis of calm yin and sound yang. "Rhythmic instability" runs through the entire process of the occurrence and development of myopia， covering four aspects including imbalance of rhythm （high-risk period of myopia）， imbalance of qi and blood （premyopia）， imbalance of sinew-membranes （low myopia）， and imbalance of essence and blood （high myopia）. The treatment should focus on adjusting the rhythm and harmonizing situation， which can help balance yin and yang， and nourish the eye system. For high-risk period of myopia， adjusting sleeping time and increasing outdoor activities are stressed to adjust the rhythm in a timely manner. In the stage of premyopia， appropriate techniques of traditional Chinese medicine （TCM） such as pressing needles can be added to harmonize qi and blood. In the period of low myopia， appropriate TCM techniques such as pressing needles and ear acupuncture are mainly used， supplemented by modified Danggui Buxue Decoction （当归补血汤） to soften tendons and unblock collaterals. During the period of high myopia， it is recommended to control the development of existing disease and put focus on nourishing essence and blood， usually with Zhujing Pill （驻景丸） or modified Siwu Wuzi Decoction （四物五子汤） to restore the stability of the eyes and the whole body.

Objective:To investigate the clinical and pathological features and improve the acknowledgement of intraductal tubulopapillary neoplasm (ITPN) of pancreas.Methods:Six cases with ITPN in the Shandong Provincial Hospital Affiliated to Shandong First Medical University combined with 40 cases from PubMed and CNKI were retrospectively analyzed. There were 25 males and 21 females, aged (58.6±16.0) years. The clinical manifestations, pathological features, treatment and so on were analyzed.Results:All cases were treated with surgery. The main clinical symptoms were upper abdominal pain and discomfort (23 cases, 50.0%), followed by jaundice (9 cases, 19.6%). Seven cases (15.2%) had no clinical symptoms. Three cases (6.5%) had low back discomfort, chills and other rare symptoms, and 4 cases (8.7%) had no clinical symptoms mentioned in the literature. Tumors of 27 cases (58.7%) located in the head of the pancreas, 9 cases (19.6%) in the body and tail, 4 cases (8.7%) in the whole pancreas, 3 cases (6.5%) in the body, 2 cases (4.3%) in ampulla and 1 case (2.2%) in head and body. Most of the tumors located in the main pancreatic duct. Microscopically, back-to-back tubular glands were densely arranged, parts of them with papillary structure, with obvious cell atypia and many mitoses. Twenty-two cases (47.8%) of ITPN were completely confined to the pancreatic duct, and 24 cases (52.2%) were with associated invasive carcinoma. Tumor cells were positive for cytokeratin 7 and mucin 1, but negative for cytokeratin 20, synaptophysin, chromogranin and trypsin. Mucin 2, mucin 5AC and mucin 6 were negative in most cases. Ki-67 ranged from 10% to 70%.Conclusion:Pancreatic ITPNs were mostly located in the pancreatic head, confined to the main pancreatic duct, and were mostly manifested as pain and discomfort in the upper abdomen. Surgery was the main treatment. Tumors cells of ITPN were arranged in tubular and papillary, with severe epithelial atypia and special immunophenotype, parts of cases accompanied with associated invasive carcinoma.

Background Nitrosamines (NAms) are highly carcinogenic and frequently detected in drinking water systems in China, indicating potential human health risk through drinking water. Objective To analyze the distribution of NAms in drinking water in Shanghai and to evaluate relevant human health risk. Methods A total of 94 samples of source water and 120 samples of finished water were collected in February (dry period) and August (wet period) of 2021 from 30 drinking water plants in Shanghai, and eight NAms were quantitatively analyzed by gas chromatography tandem mass spectrometry after solid phase extraction. Cancer risks for different age groups caused by NAms exposure through water were evaluated using Monte Carlo probabilistic method and carcinogens risk assessment model recommended by the United States Environmental Protection Agency. Results The concentrations of total NAms in source and finished water were 12.56-65.86 ng·L⁻¹ and 8.52-57.38 ng·L⁻¹, respectively. The average concentration of total NAms was higher in source water (33.50 ng·L⁻¹) than in finished water (22.07 ng·L⁻¹, P<0.05) during dry season, and lower in source water (16.90 ng·L⁻¹) than in finished water (21.02 ng·L⁻¹, P<0.05) during wet season. The average concentration of total NAms in source water during dry season was twice of that during wet season. The positive rate of N-nitrosodimethylamine (NDMA) was the highest (100%) among the eight NAms. The cancer risk of exposure to NAms in finished water in Shanghai was mainly from the ingestion route, which was mostly caused by NDMA. The cancer risk from exposure to NAms in water for children (median=4.32×10⁻⁵) was slightly higher than that for adults (median=3.34×10⁻⁵) and adolescents (median=2.27×10⁻⁵). The cancer risks of exposure to NAms in water for people of different ages were mainly (80% - 95%) at an acceptable level (1×10⁻⁶ - 1×10⁻⁴). Conclusion NAms contamination is positive in Shanghai’s drinking water and NDMA is the main contaminant. The removal of NAms in water by current water treatment process is season-dependent. The cancer risk of children exposed to NAms in water was slightly higher than that of adults and adolescents, but all at acceptable levels.

Objective: To observe changes in the molecular expression of the NLR Family Pyrin Domain Containing Protein 3 (NLRP3) pathway in depressed rats after treatment with Xiaoyaosan, and identify the regu-latory mechanism of this compound. Methods: Male Sprague-Dawley rats were randomly divided into five groups with 12 rats in each group, including the control group, model group, Fluoxetine group, Xiaoyaosan group, and MCC950 group. A depression model was generated by chronic immobilization stress (induced by 3 h of restraint immo-bilization every day), and the drugs were administered at the same time in each group for 21 days. The effects of Xiaoyaosan on behavioral changes of depressed rats were observed through macroscopic characterization, body mass, open field experiments, and a sucrose preference test. The mRNA and protein expression of the NLRP3 signaling pathway was examined by fluorescence real-time quantitative PCR and Western blot assays. Results: The Xiaoyaosan group, Fluoxetine group, and MCC950 group rats showed improved depressive behavior and an increased weight of sucrose water consumption. The protein and mRNA expression levels of NLRP3, Caspase-1, and IL-1β were also decreased in the Fluoxetine, Xiaoyaosan, and MCC950 groups. Conclusion: NLRP3, Caspase-1, and IL-1β protein and mRNA expression levels were increased in the cortex of depressed rats, while Xiaoyaosan protected cortical tissue in these rats by decreasing NLRP3, Caspase-1, and IL-1βprotein and mRNA expression.
