Immunoglobulin A (IgA) nephropathy is a globally prevalent type of primary glomerulonephritis, characterized by complex symptoms and diverse clinical manifestations. The internationally recognized " multiple hit hypothesis" explains the systemic immune disease features of IgA nephropathy. However, current treatment strategies primarily focus on local pathological changes, inadequately addressing its complex systemic mechanisms. The " qi cycle in round" theory, an integral concept of the academic thought of HUANG Yuanyu, a prominent medical expert from the Qing Dynasty, offers a concise and insightful framework for understanding complex pathologies. For example, this theory provides valuable insights for elucidating the pathogenesis of IgA nephropathy and guiding its clinical management by simplifying intricate systemic processes. This study applies the " qi cycle in round" theory to postulate that patients with IgA nephropathy experience disrupted qi flow owing to spleen-stomach qi deficiency and dampness-heat accumulation. These imbalances manifest as internal symptoms, such as diarrhea; external vulnerability to illness; upper body symptoms, like sore throat; and lower body symptoms, such as hematuria and proteinuria. Pathologically, the condition is characterized by immune complex deposition. This article also emphasizes strategies that prioritize tonifying spleen-stomach qi to enhance the pivotal functions of transportation and transformation. Regulating qi and relieving stagnation are emphasized to harmonize ascending and descending dynamics. Additionally, eliminating turbidity and unblocking collaterals are highlighted to promote qi transformation. These approaches aim to restore the harmonious operation of organ qi dynamics and harmonious qi transformation functions. This study aims to provide a reference for syndrome differentiation and IgA nephropathy treatment using traditional Chinese medicine based on the " qi cycle in round" theory.

Diabetic retinopathy(DR)is one of the most common and severe microvascular complications in diabetic patients and has become one of the leading causes of blindness worldwide. With the continuous rise in the prevalence of diabetes, in-depth exploration of the pathogenesis of DR and effective intervention measures is of great clinical significance. The mechanistic target of rapamycin(mTOR), as a protein kinase, is widely involved in cellular processes such as growth, metabolism, and autophagy. Research indicates that the mTOR signaling pathway plays a crucial regulatory role in the pathological progression of DR, and its abnormal activity can disrupt retinal cell autophagy function, thereby accelerating cellular damage and disease progression. Autophagy, as an important regulatory mechanism for cellular homeostasis, maintains cellular functional balance by clearing damaged organelles and protein aggregates. This article provides a systematic review of the structural and functional aspects of the mTOR signaling pathway, the molecular regulatory mechanisms of autophagy, and their roles in retinal pathological changes. By summarizing current research findings, the article aims to clarify the key regulatory role of the mTOR-autophagy axis in DR, providing theoretical support for elucidating the molecular pathogenesis of DR and offering potential targets and research directions for developing novel targeted therapeutic strategies, thereby holding significant scientific and clinical value.

Due to the increasingly severe situation of pathogen resistance, the efficacy of classical antibiotics has declined, and the difficulty of treating community-acquired pneumonia (CAP) has gradually increased. Omadacycline was approved for marketing in China in December 2021 and has been approved for treating community-acquired bacterial pneumonia and acute bacterial skin and skin structure infection in adults. Based on introducing the pathogen resistance of CAP, this article systematically reviews the antibacterial activity and resistance, pharmacokinetic characteristics, and clinical efficacy of omadacycline. It is found that its antibacterial spectrum is wide, its bioavailability is high, and its safety is good. Its pharmacokinetic parameters are not affected by the patients’ age, gender, liver and kidney function, or drug interactions, and it is effective against multiple drug-resistant bacteria, Gram-negative bacteria producing extended-spectrum β-lactases, atypical pathogens, etc. It can be used as one of the treatment options for CAP. However, due to limited clinical research data and the short clinical application time of the drug, more clinical studies are still needed to verify its efficacy as a monotherapy or in combination with other antibiotics for severe pneumonia patients.

Tingli Dazao Xiefeitang is a classic formula for treating lung abscesses and thoracic fluid retention, recognized throughout history and included in the Catalogue of Ancient Classic Formulas (Second Batch). This article employs bibliometric methods to investigate and analyze the source, origin, and key information of Tingli Dazao Xiefeitang, providing a theoretical basis for the development and application of this renowned formula. The results show that Tingli Dazao Xiefeitang first appears in Synopsis of the Golden Chamber (Jin Kui Yao Lue), where three clinical applications are recorded. The original text clearly states that this formula is used to treat lung abscesses and thoracic fluid retention, with symptoms such as inability to lie down due to wheezing, chest and rib fullness, facial edema, inability to rest due to thoracic fluid retention, and cough inversion. This aligns with findings from ancient application research. In later generations, the methods proposed by ZHANG Zhongjing were predominantly used for medication and formulation. Modern applications of Tingli Dazao Xiefeitang focus primarily on the respiratory system, with pleural effusion being the most common condition. For the preparation and decoction, a single dose of 5 g of Descurainiae Semen Lepidii Semen (dried and mature seeds of Lepidium apetalum) processed as stir-fried seeds and 36 g of Jujubae Fructus (dried and mature fruit of Ziziphus jujuba) prepared as raw materials were recommended. Then 600 mL of water was added and Jujubae Fructus was first boiled until the volume reduced to 400 mL. After filtering out the residue, the supernatant was retained and mixed with stir-fried Descurainiae Semen Lepidii Semen, followed by boiling to 200 mL, which should be consumed all at once. This research provides a theoretical basis for the development and application of this formula.

Diabetic retinopathy(DR)is one of the common causes of visual impairment and blindness in adults, which is caused by various pathogenesis. Although the mechanism of DR has not been elucidated yet, the destruction of blood-retinal barrier is a key process. As a highly endothelial-specific factor in promoting the growth of vascular endothelial cell, vascular endothelial growth factor(VEGF)plays a crucial role in the formation of pathological retinal neovascularization and the destruction of blood-retinal barrier. Therefore, a comprehensive understanding of the etiology and pathogenesis of blood-retinal barrier damage promoted by VEGF is critical for exploring the pathogenesis of DR. In this study, the underlying relationship between VEGF and the mechanism of blood-retinal barrier damage, including retinal vascular endothelial cell permeability, vascular inflammatory response, apoptosis, oxidative stress, mitochondrial damage and endoplasmic reticulum stress, with a view to providing a reference for the study in VEGF in the pathogenesis of blood-retinal barrier damage in DR.

Objective:To analyze the depressive symptoms of physical and mental workers and the impact of their behavior and lifestyle on their depressive symptoms.Methods:In August 2022, a cross-sectional study design was adopted to select 553 workers as research subjects using cluster sampling. General demographic information, health-related behaviors and lifestyles were collected, and their depressive symptoms were evaluated using the Chinese version of the Patient Health Questionnaire 9 (PHQ-9). The differences in general demographic information, health-related behaviors and lifestyles between physical and mental workers were analyzed, and logistic regression was used to analyze the influencing factors of depressive symptoms in occupational populations.Results:Among the 553 subjects, 317 were physical workers (57.32%) and 236 were mental workers (42.68%). Statistically significant differences were observed between the two groups in terms of education level, monthly income, smoking rate, regular physical exercise rate and appropriate sleep time rate ( P<0.05). The score and the detection rate of depression symptoms among physical workers were (9.67±2.75) points and 20.82% (66/317), respectively, which were higher than those of mental workers [(8.34±2.18) points, 12.71% (30/236) ] ( t=6.13, χ 2=6.20, P<0.05). The results of logistic regression analysis showed that smoking, regular physical exercise, appropriate sleep time and mental work were influencing factors of depressive symptoms among the occupational population ( OR=1.592, 95% CI: 1.316-1.825; OR=0.659, 95% CI: 0.416-0.830; OR=0.502, 95% CI: 0.257-0.717; OR=0.839, 95% CI: 0.522-0.967; P<0.05) . Conclusion:The depressive symptoms of physical workers are more serious than those of mental workers. Low education level, not frequently participating in physical exercise, smoking and sleep disorder are potential risk factors that affect the depressive symptoms of the occupational population.

To explore the biological characteristics related to the pathogenesis and severity of respiratory syncytial virus (RSV) bronchiolitis by RNA sequencing of white blood cells in children with RSV bronchiolitis. This study is a case-control study. A total of 87 children diagnosed with bronchiolitis and RSV antigen positive and/or RSV nucleic acid positive in the pediatric respiratory department of the Second Affiliated Hospital of Wenzhou Medical University from October 2019 to April 2022 were selected as the case group. The case group was divided into three groups based on the condition: mild, moderate, and severe, and there were two groups according to the presence or absence of atopic symptoms: the atopic group and the non -atopic group, forty healthy children in the same period were selected as the control group. The whole blood leukocyte RNA of the children in the case group and the control group was extracted for RNA sequencing, and the data were analyzed to obtain differentially expressed genes (DEGs). Then, the immunobiological pathways and genes related to the pathogenesis, disease condition, and atopy were screened through Gene Ontology (GO) annotation, Kyoto Gene and Genome Encyclopedia (KEGG) annotation, and protein interaction network (PPI) construction methods. Construct the weighted gene co-expression network analysis (WGCNA) module to identify potential biological indicators related to disease severity.Compared with the control group, the case group had a total of 1 782 DEGs, including 1 586 upregulated genes and 196 downregulated genes. The GO pathway enrichment of DEGs is mainly enriched in molecular functions such as peroxidase activity and oxidoreductase activity. In the cytological components, it is mainly enriched in cytoplasmic vesicle lumen and secretory granule lumen. In biological processes, it is mainly enriched in processes such as neutrophil activation involved in immune responses, neutrophil degranulation, and neutrophil activation. KEGG analysis is mainly concentrated in the signal pathway of the viral protein interaction with cytokine and cytokine receptor. A PPI network was constructed to screen four genes at the core position, including CCL2, IL-10, MMP9 and JUN. The DEGs obtained by comparing different disease groups with the control group are mainly enriched in retrograde endocannabinoid signaling and cell apoptosis pathways. WGCNA analysis showed that the brown module related to oxygen saturation was most closely related to the disease, and its gene was mainly enriched in the RNA helicase retinoic acid inducible gene-I (RIG-I) like receptor signal pathway. There are 230 specific DEGs in the atopic group and 444 in the non -atopic group. KEGG enrichment analysis results show that both groups are enriched to NF-κB signaling pathway, the characteristic does not cause significant changes in immune response and transcriptome characteristics in children with RSV bronchiolitis. In conclusion, neutrophil activation, degranulation pathway and signal pathway of interaction between viral protein and cytokine and cytokine receptor are involved in the immune response of RSV bronchiolitis host. CCL2, IL-10, MMP9 and JUN genes may be associated with the pathogenesis. They might be potential biomarkers related to disease severity in RIG-I like receptors, cell apoptosis, and endogenous cannabinoid related signaling pathways.
