The etiology of tumors is complex and influenced by multiple factors, including the host and environmental conditions. Allergy is primarily driven by the immune response of helper T cell 2 (Th2). Research has shown that the Th2 immune response is closely related to tumors, which is specifically manifested through Th2 antibodies, allergy-related effector cells and mediators within the tumors, as well as tumor immune-related functions. This internal interaction mechanism will increase the complexity and challenges associated with the clinical diagnosis and treatment of tumors and allergy. The formation of allergic constitution is shaped by both congenital and acquired factors, and its physical state is closely linked to the occurrence and progression of allergic diseases. Therefore, this paper aims to explore the relationship between tumors and allergic reactions from the perspective of traditional Chinese medicine (TCM) constitution theory. Based on the four basic principles of the TCM constitution, including endowment inheritance theory, environment constraint theory, body-spirit composition theory, and life process theory, this exploration will focus on four aspects: genetic factors and internal disease causes, inflammatory environments and functional regulation, psychological disorders and emotional pathogenesis, as well as age structure and disease risk. Furthermore, from the perspective of constitution-disease relation of chronic disease prevention, this paper will discuss the significant importance of adjusting allergic constitution to improve both subjective symptoms and objective indicators of allergic reactions in tumor patients.

AIM: To investigate the changes of microRNA-34a(miR-34a)and microRNA-29b(miR-29b)levels in lens epithelial cells of age-related cataracts(ARC)patients and their clinical significance.METHODS: A total of 65 ARC patients(study group)and 53 cases of clear lens anterior capsulorhexis(control group)who visited our hospital from February 2023 to February 2024 were gathered. Pearson was applied to test the correlation between miR-34a and miR-29b. Multifactor Logistic regression was applied to determine the factors affecting the occurrence of ARC.RESULTS: Compared with the control group, the expression levels of miR-34a and miR-29b in lens epithelial cells of the research group showed a significant decrease trend(all P<0.05). There was a positive correlation between miR-34a and miR-29b in the lens epithelial cells of ARC patients(r=0.472, P<0.05). MiR-34a and miR-29b were influence factors for ARC(all P<0.05).CONCLUSION: The levels of miR-34a and miR-29b in lens epithelial cells of ARC patients are significantly reduced, which is associated with the occurrence of ARC.

ObjectiveTo analyze the epidemiological characteristics of newly diagnosed occupational welder's pneumoconiosis (OWP) in the shipbuilding industry in Guangzhou City from 2006 to 2022. Methods Data on newly diagnosed OWP cases in the shipbuilding industry in Guangzhou City from 2006 to 2022 was collected and ananlyzed from the Health Hazard Monitoring Information System subsystem of the Chinese Disease Prevention and Control System. ResultA total of 250 cases of new welder's pneumoconiosis were diagnosed in the shipbuilding industry in Guangzhou City from 2006 to 2022. The number of new cases per year showed an initial increase followed by a rapid decline, reaching a peak in 2013 (65 cases). Most of the cases were male, accounted for 99.2%. There were 220 cases reported the OWP stage, with the stage Ⅰ and stage Ⅱ cases accounted for 93.6% and 6.4%, respectively, but no stage Ⅲ cases were reported. The median (M) age and the 25th and 75th percentiles (P₂₅, P₇₅) at diagnosis was 43.0 (39.0, 47.0) years and the dust exposure years M (P₂₅, P₇₅) was 11.2 (8.1, 14.7) years. The M of age at diagnosis of new OWP cases in 2015-2018 and 2019-2022 were higher than those in 2006-2010 and 2011-2014, respectively (all P<0.05). The M of dust exposure duration of new OWP cases from 2006-2010 and 2019-2022 was higher than that in cases from 2015-2018 and 2011-2014, respectively (all P<0.05). Most of the small shadows of the cases were circular small p shadows and distributed in the bilateral middle and lower lung zones, with a density mostly of 1/1, according to the X-ray chest films. Conclusion The hazard of welding fumes in the shipbuilding industry in Guangzhou City has been controlled, but the prevention and control of OWP among welders remains severe.

Hydration status refers to the balance between the intake and discharge of water in the body. When the ingested and discharged water are roughly equal and the body is in water balance, it is the normal hydration status, and when the water intake is too little or too much, it is the "dehydration" or "overhydration status". The hydration status of the body not only affects metabolism, but also affects the functions of the urinary system, cardiovascular system, nervous system, etc. In order to further clarify the relationship between body hydration status and decompression sickness (DCS), this paper reviewed relevant studies and analyzed the interaction between hydration and decompression safety during diving. The primary causes of dehydration in diving are "hyperbaric diuresis", "immersion diuresis", breathing dry gas, heat, and cold. Dehydration not only promotes the occurrence of DCS but also reduces the aerobic work efficiency and athletic performance of divers, as well as affects cognition and mood. A study found that appropriate rehydration before and during diving can reduce the risk of DCS, which possibly associates with the increase of blood volume, plasma surface tension, and vasoconstriction. Fluid therapy is also important for those who already have DCS. This paper analyzed the amount, nature, timing, and effect of rehydration involved in the above links, comprehensively sorted out the relationship between hydration and diving safety, summarized the existing problems, and provided reference for practical application and future research.

In order to establish a rapid,specific and sensitive detection method for Streptococcus equi subspecies zooepidemicus(SEZ)and to understand the infection status of SEZ in horses ente-ring China,specific primers were designed and synthesized based on the conserved gene comB of standard strain SEZ(ATCC 43079)in this work.Then,the pMD19-T-comB recombinant plasmid was constructed and used as a standard positive template.After that,the fluorescence-based quantitative PCR(qPCR)detection method based on SYBR Green Ⅰ dye was established.Totally,477 equine entry serum samples from 6 countries,including Netherlands,Belgium,Japan,Germa-ny,Argentina and New Zealand,during 2018 to 2023,were randomly selected and detected for SEZ by the qPCR method.Results showed that the established qPCR method had specific amplification for only SEZ,which illustrated a good specificity.Sensitivity test of the method showed that the limited detection amount was 4.58 X101 copies/μL.And the repeatability test showed that the coef-ficient of variation of intra-batch repeatability was less than 0.5％,while the inter-batch repeat-ability was less than 3.0％,which indicated good repeatability and high stability.Retrospective a-nalysis showed that totally 11 of 477 positive samples were detected,with a relatively low positive rate of 2.31％(11/477).Among them,all the 40 samples from Netherlands in 2018 were negative(0/40).In the samples of 2019,one positive was detected from Belgium(1/20),while all other 36 samples which form Japan and Germany were negative.In the samples of 2021,three samples(3/34)from Japan and one sample(1/20)from Argentina were positive,and all the other 40 samples from the Netherlands were negative.In the samples of 2022,76 samples from Netherlands were all negative.While in the 2023,5(5/126)of 126 samples from Netherlands and one(1/88)of 88 from New Zealand were found positive with SEZ.To summarize,The SYBR Green Ⅰ qPCR method for the diagnosis of SEZ was successfully established,and it could provide necessary technical support for the rapid quarantine of China's entry-exit and port departments,as well as the epidemiological investigation of the disease.

Nerve regeneration in adult mammalian spinal cord is poor because of the lack of intrinsic regeneration of neurons and extrinsic factors - the glial scar is triggered by injury and inhibits or promotes regeneration. Recent technological advances in spatial transcriptomics (ST) provide a unique opportunity to decipher most genes systematically throughout scar formation, which remains poorly understood. Here, we first constructed the tissue-wide gene expression patterns of mouse spinal cords over the course of scar formation using ST after spinal cord injury from 32 samples. Locally, we profiled gene expression gradients from the leading edge to the core of the scar areas to further understand the scar microenvironment, such as neurotransmitter disorders, activation of the pro-inflammatory response, neurotoxic saturated lipids, angiogenesis, obstructed axon extension, and extracellular structure re-organization. In addition, we described 21 cell transcriptional states during scar formation and delineated the origins, functional diversity, and possible trajectories of subpopulations of fibroblasts, glia, and immune cells. Specifically, we found some regulators in special cell types, such as Thbs1 and Col1a2 in macrophages, CD36 and Postn in fibroblasts, Plxnb2 and Nxpe3 in microglia, Clu in astrocytes, and CD74 in oligodendrocytes. Furthermore, salvianolic acid B, a blood-brain barrier permeation and CD36 inhibitor, was administered after surgery and found to remedy fibrosis. Subsequently, we described the extent of the scar boundary and profiled the bidirectional ligand-receptor interactions at the neighboring cluster boundary, contributing to maintain scar architecture during gliosis and fibrosis, and found that GPR37L1_PSAP, and GPR37_PSAP were the most significant gene-pairs among microglia, fibroblasts, and astrocytes. Last, we quantified the fraction of scar-resident cells and proposed four possible phases of scar formation: macrophage infiltration, proliferation and differentiation of scar-resident cells, scar emergence, and scar stationary. Together, these profiles delineated the spatial heterogeneity of the scar, confirmed the previous concepts about scar architecture, provided some new clues for scar formation, and served as a valuable resource for the treatment of central nervous system injury.

The chemical complexity of traditional Chinese medicines (TCMs) makes the active and functional annotation of natural compounds challenging. Herein, we developed the TCMs-Compounds Functional Annotation platform (TCMs-CFA) for large-scale predicting active compounds with potential mechanisms from TCM complex system, without isolating and activity testing every single compound one by one. The platform was established based on the integration of TCMs knowledge base, chemome profiling, and high-content imaging. It mainly included: (1) selection of herbal drugs of target based on TCMs knowledge base; (2) chemome profiling of TCMs extract library by LC‒MS; (3) cytological profiling of TCMs extract library by high-content cell-based imaging; (4) active compounds discovery by combining each mass signal and multi-parametric cell phenotypes; (5) construction of functional annotation map for predicting the potential mechanisms of lead compounds. In this stud TCMs with myocardial protection were applied as a case study, and validated for the feasibility and utility of the platform. Seven frequently used herbal drugs (Ginseng, etc.) were screened from 100,000 TCMs formulas for myocardial protection and subsequently prepared as a library of 700 extracts. By using TCMs-CFA platform, 81 lead compounds, including 10 novel bioactive ones, were quickly identified by correlating 8089 mass signals with 170,100 cytological parameters from an extract library. The TCMs-CFA platform described a new evidence-led tool for the rapid discovery process by data mining strategies, which is valuable for novel lead compounds from TCMs. All computations are done through Python and are publicly available on GitHub.

Objective:To analyze the effect of Excel tabular nutrition assessment management combined with mental awareness intervention in patients with chronic renal failure.Methods:Using the convenient sampling method, a total of 90 patients with chronic renal failure who were treated in Department of Nephrology of Huai'an Second People's Hospital in Jiangsu Province from January to December 2020 were selected. They were divided into the control group and the research group by computer random number method, with 45 cases in each group. The control group was given routine nursing and mental awareness intervention, while the research group was given Excel tabular nutrition assessment management on the basis of the control group. Self-Rating Anxiety Scale (SAS) , Self-Rating Depression Scale (SDS) , Mindful Attention Awareness Scale (MAAS) and Kidney Disease Quality of Life Short Form (KDQOL-SFTM) were respectively used to evaluate the level of adverse psychology, mental awareness and quality of life of patients in two groups. The levels of nutritional indicators, adverse psychological mood, mental awareness and quality of life were compared between the two groups.Results:SAS score and SDS score of the two groups after intervention were lower than before intervention, and that of the research group was lower than the control group. The MAAS score of the two groups after intervention was higher than before, and that of the research group was higher than the control group. Quality of life scores in both groups were higher than before intervention and those of the research group were higher than the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The application of Excel tabular nutrition assessment management combined with mental awareness intervention in patients with chronic renal failure can relieve negative emotions of patients, improve their mental awareness and improve their quality of life.

Objective:To summarize retrospectively the postoperative therapeutic effect of composite orbital fracture.Methods:587 patients with orbital fracture were assessed and diagnosed according to their clinical symptoms and 3D-CT reports before surgeries where incarcerated soft tissue is released and replaced thoroughly, with orbit reset as well as implants used to fix it, and then we evaluated the surgical outcomes by comparing the postoperative outlines of patients’ orbits, the functions of eyeballs along with their 3D-CT evidences.Results:After 10-month to 2-year postoperative follow-up, 12 cases of 587 who had apparent enophthalmos preoperatively still have slightly postoperative symptoms. Although the diplopia of 9 cases is partially recovered, their eye movement remain slightly restricted. In addition, the eye function of other patients didn’t dramatically decline in comparison with that of pre-trauma, except for those undergoing enucleation of eyeballs due to ophthalmorrhexis.Conclusions:Orbital fracture should be diagnosed and evaluated rigorously based on patients’ symptoms and 3D-CT reports, improving treatment effects by accurate reset, fixation and repair at early stage.
