Dry eye disease(DED)is a multifactorial disorder with an unclear pathogenesis. Advances in omics technologies have introduced a novel medical research approach, enabling the identification of global response variables from a single-factor perspective. However, multi-omics methods integrate multiple omics datasets to analyze all potential response variables, generating multidimensional and evidence-supported holistic inferences. These insights help elucidate functional impairments of ocular cells and biomolecular processes during disease progression, thereby revealing correlations between biomolecules and complex diseases. This review summarizes the application of multi-omics technologies in clarifying the pathogenesis and intricate molecular mechanisms of dry eye disease. Distinctive features from genomics, transcriptomics, proteomics, metabolomics, and microbiomics are integrated to deepen the understanding of the pathogenesis and complex molecular mechanisms underlying dry eye disease.

Thyroid nodules are a common endocrine disorder, and their early detection and accurate diagnosis are crucial for the prevention of thyroid cancer. However, the highly heterogeneous morphology and boundaries of thyroid nodules pose significant challenges to their precise identification and classification. Traditional diagnostic approaches rely heavily on physicians' experience, which increases the risk of misdiagnosis and missed diagnoses. With the rapid advancement of computer-aided diagnosis (CAD) technologies, applying deep learning algorithms to the analysis of thyroid nodule ultrasound images has shown great potential. This paper reviews the latest research progress on deep learning-based CAD methods for thyroid nodules, with a focus on their applications in image preprocessing, segmentation and classification. The advantages and limitations of current techniques are analyzed, and potential future directions are discussed. This review aims to highlight the potential of deep learning in thyroid nodule diagnosis and to provide a foundation for selecting feasible pathways for future clinical applications.

Objective To elucidate the molecular mechanism by which exosomes (Exo) derived from cancer-associated fibroblasts (CAF) carrying HOX transcript antisense intergenic RNA (lncRNA HOTAIR) promote the metastasis of esophageal squamous cell carcinoma (ESCC). Methods CAFs were collected from tumor tissues, and non-cancer associated fibroblasts (NFs) were obtained from adjacent normal tissues at least 5 cm away from the tumor. Exosomes (CAFs-Exo and NFs-Exo) were isolated from conditioned media collected from CAFs or NFs. CAFs-Exo and NFs-Exo were incubated with human ESCC cell line TE-1 for 24 hours, and CCK-8 was used to determine the cell proliferation ability. Scratch test and Transwell test were performed to determine the cell migration and invasion ability. TE-1 cells were divided into the following two groups: NC group and KD group. The NC group and KD group were transfected with control siRNAs or siRNAs targeting HOTAIR respectively. The effects of HOTAIR knock-down on cell proliferation, migration, invasion and glycolysis were determined. Results CAFs-Exo promoted the proliferation of TE-1 cells more significantly than NFs-Exo. Compared with NFs-Exo group, the migration and invasion ability of TE-1 cells treated with CAFs-Exo were improved significantly. In addition, CAFs-Exo treatment inhibited the expression of E-cadherin and enhanced the expression of N-cadherin. The expression of HOTAIR in CAFs was significantly higher than that in NFs. Compared with NFs-Exo, the expression level of HOTAIR in CAFs-Exo increased significantly. Compared with NC group, the proliferation, migration and invasion of TE-1 cells in KD group decreased significantly. Compared with NC group, hexokinase 2 (HK2), extracellular acidification rate (ECAR) and ATP/ADP ratio of TE-1 cells in KD group decreased significantly. Conclusion HOTAIR, an exosome derived from CAFs, may be involved in metastasis and EMT by regulating glycolysis in ESCC cells.

Glioma, the most prevalent primary tumor of the central nervous system (CNS), is also the most lethal primary malignant tumor. Currently, there are limited chemotherapeutics available for glioma treatment, necessitating further research to identify and develop new chemotherapeutic agents. A significant approach to discovering anti-glioma drugs involves isolating antitumor active ingredients from natural products (NPs) and optimizing their structures. Additionally, targeted drug delivery systems (TDDSs) are employed to enhance drug solubility and stability and overcome the blood-brain barrier (BBB). TDDSs can penetrate deep into the brain, increase drug concentration and retention time in the CNS, and improve the targeting efficiency of NPs, thereby reducing adverse effects and enhancing anti-glioma efficacy. This paper reviews the research progress of anti-glioma activities of NPs, including alkaloids, polyphenols, flavonoids, terpenoids, saponins, quinones, and their synthetic derivatives over the past decade. The review also summarizes anti-glioma mechanisms, such as suppression of related protein expression, regulation of reactive oxygen species (ROS) levels, control of apoptosis signaling pathways, reduction of matrix metalloproteinases (MMPs) expression, blocking of vascular endothelial growth factor (VEGF), and reversal of immunosuppression. Furthermore, the functions and advantages of NP-based TDDSs in anti-glioma therapy are examined. The key information presented in this review will be valuable for the research and development of NP-based anti-glioma drugs and related TDDSs.

Chlorobenzene contaminants (CBs) pose a threat to the eco-environment, and functional strains hold considerable potential for the remediation of CB-contaminated sites. To deeply explore the application potential of functional bacteria in the in-situ bioremediation of CBs, this study focused on the biodegradation characteristics and degradation kinetics of CB and 1, 2-dichlorobenzene (1, 2-DCB) in soil by the isolated strain Serratia marcescens TF-1. Additionally, an in-situ remediation trial was conducted with this strain at a chemical industrial site. Batch serum bottle experiments showed that the degradation rate of CB at the concentrations ranging from 20 to 200 mg/L by TF-1 was 0.22-0.66 mol/(gcell·h), following the Haldane model, with the optimal concentration at 23.12 mg/L. The results from simulated soil degradation experiments indicated that the combined use of TF-1 and sodium succinate (SS) significantly enhanced the degradation of CBs, with the maximum degradation rate of CB reaching 0.104 d-1 and a half-life of 6.66 d. For 1, 2-DCB, the maximum degradation rate constant was 0.068 7 d-1, with a half-life of 10.087 d. The in-situ remediation results at the chemically contaminated site demonstrated that the introduction of bacterial inoculant and SS significantly improved the removal of CBs, achieving the removal rates of 84.2%-100% after 10 d. CB, 1, 4-dichlorobenzene (1, 4-DCB), and benzo[a]pyrene were completely removed. Microbial diversity analysis revealed that the in-situ remediation facilitated the colonization of TF-1 and the enrichment of indigenous nitrogen-fixing Azoarcus, which may have played a key role in the degradation process. This study provides a theoretical basis and practical experience for the in situ bioremediation of CBs-contaminated sites.

The intraoperative indicators, vertebral changes before surgery and 6 months after surgery, and the occurrence of adverse reactions after surgery of the two groups of patients were compared. The visual analogue scale (VAS), activities of daily living (ADL) score, oswestry disability index (ODI), and quality of life (QOL) scale were used to compare the pain degree, activity ability, improvement of functional disability, and changes in quality of life and clinical efficacy of the two groups of patients before the operation and at 3 and 6 months after the operation. SPSS 21.0 software was conducted to analyze data. Measurement data with normal distribution were represented as mean±standard deviation( ± s), and the comparison between groups was conducted using the t-test. The comparison of count data were represented as n(%) and was conducted by χ2 test or Fisher exact probability. Between-group comparisons of different time intervals were performed with repeated-measures analysis of variance test. Results:The surgical time, cement dosage, bleeding amount, and fluoroscopy of patients in the unilateral group were (29.86±5.87) min, (2.58±0.37) mL, (22.65±4.83) mL, and 12 times, respectively, and (42.63±4.55) min, (7.12±0.61) mL, (50.31±5.84) mL, 25 times in the bilateral group, respectively. The difference between the two groups was statistically significant ( P<0.05). Preoperatively, the anterior height ratio of the vertebral body, sagittal concavity angle, and kyphosis angle of the affected vertebra in the unilateral group were (59.83±5.55)%, 13.04°±1.14°, and 18.93°±2.56°, respectively, while in the bilateral group, there were (60.28±5.79)%, 13.08°±1.13°, and 18.67°±2.69°, respectively. After the operation, the unilateral group were (90.20±5.52), 3.95°±0.57°, and 11.03°±1.21°, respectively. The bilateral group were (90.58±6.00), 3.99°±0.59°, and 10.91°±1.14°, respectively. Comparison of data before and after surgery between the two groups, the difference was statistically significant ( P<0.05). The overall complication rate of unilateral group was 13 cases (6.70%), and the overall complication rate of bilateral group was 26 cases (14.61%). The difference between the two groups was statistically significant ( P=0.013). The VAS, ADL, ODI, and QOL of the unilateral group were (3.49±1.10), (66.10±13.02), (18.22±4.81) and (62.10±10.00) points, the two-sided groups were (5.49±1.13), (56.19±10.27), (24.76±5.81) and (52.13±9.56) points, respectively. The differences between the two groups were statistical significance ( P<0.05), the overall treatment efficiency of patients in the unilateral group was 90.72%, and the overall treatment efficiency of patients in the bilateral group was 83.15%, and the difference between the two groups was statistically significant( P<0.05). Conclusions:Unilateral puncture vertebroplasty has the advantages of short operation time, less bone cement usage, low blood loss, fewer fluoroscopy times, low complication rate, better postoperative pain relief and functional recovery, and high overall treatment efficiency in the treatment of patients with osteoporotic compression fractures. It has obvious advantages over bilateral puncture vertebroplasty.

Objective:To investigate the liver-protective effect of Peipi Shugan Decoction (PSD) in rats with liver fibrosis through network pharmacology and experimental animal models.Methods:TCMSP was used to retrieve the active components of Peipi Shugan Decoction, GeneCards database was used to obtain the liver fibrosis related targets, and Venny 2.1 was used to obtain the intersection targets. A protein-protein interaction (PPI) network was constructed using the STRING 12.0 database, and Go function and KEGG pathway enrichment analysis were performed through David database. A total of 60 male Sprague-Dawley (SD) rats were divided into two groups: a blank control group ( n=10) and a model establishment group ( n=50) with random number table method. Liver fibrosis models were induced in the model group by intraperitoneal injection of a 40% CCl?- olive oil solution. After successful modeling, the rats were randomly assigned to the following groups ( n=10 per group): model group, colchicine group, and Peipi Shugan Decoction low-, medium-, and high-dosage groups. The colchicine group received colchicine suspension at 0.2 ml/kg via intragastric administration. Peipi Shugan Decoction low-, medium-, and high-dosage groups were administered the decoction at dosages of 2.81, 5.63, and 11.25 g/kg, respectively. The blank control and model groups received an equal volume of normal saline. All treatments were administered once daily for 8 consecutive weeks. HE staining and Masson staining were used to observe the morphological changes of liver tissue and the deposition of collagen fibers. he levels of GPT, GOT and ALP were detected by automatic biochemical analyzer. The expressions of JAK2/STAT1 signaling pathway related proteins, α - smooth muscle actin (α-SMA) and Collagen Ⅰ in rat liver were detected by Western blot. The expression of α-SMA protein in liver tissue was detected by immunohistochemistry. The number and ratio of CD4 + T cells and CD8 + T cells in liver tissue were analyzed by flow cytometry. The levels of IL-6, IL-1β and TNF-α in serum were detected by ELISA. Results:A total of 94 active components were screened out from Peipi Shugan Decoction; the prediction analysis results revealed that this compound formula shared 122 common targets with liver fibrosis diseases; The top five core targets with degree values in the PPI network are AKT1, TNF, IL-6, TP53, and IL-1β. GO enrichment analysis further indicated that Peipi Shugan Decoction mainly achieved anti-liver fibrosis effects by regulating JAK2/STAT1 signaling pathway and other mechanisms. Compared with the model group, the colchicine group and Peipi Shugan Decoction low-, medium-, and high-dosage groups exhibited decreased serum levels of GPT, GOT, ALP, IL-6, TNF-α, and IL-1β ( P<0.05), as well as reduced expression of α-SMA in liver tissue ( P<0.05). Peipi Shugan Decoction medium- and high-dosage groups showed increased protein expression of p-STAT1/STAT1 in liver tissue ( P<0.05), while Peipi Shugan Decoction high-dosage group demonstrated decreased α-SMA protein expression ( P<0.05). Additionally, Peipi Shugan Decoction medium- and high-dosage groups exhibited reduced expressions of CD4 + and CD8 + ( P<0.05). Conclusions:Peipi Shugan Decoction has the characteristics of multi-component, multi-target and multi-pathway in the treatment of liver fibrosis. Its mechanism is mainly related to activating the JAK2/STAT1 signaling pathway, inhibiting cellular inflammatory responses and hindering the activation of hepatic stellate cells (HSC).
