Uveal melanoma(UM)is the most common primary intraocular malignancy in adults, characterized by high invasiveness and unique metastatic biological features. Although local treatments(such as proton beam therapy and brachytherapy)can effectively control the primary lesion, approximately 50% of patients eventually develop distant metastasis, with the liver being the primary target organ(occurring in 90% of cases). This highlights a paradigm shift in treatment focus from mere local control to systemic prevention and management. For metastatic UM(mUM), current treatment strategies encompass biomarker-guided molecular targeted therapy, immunotherapy(including Tebentafusp, vaccines, and oncolytic virus therapy), and liver-directed therapy. Focusing on the synergy between local and systemic prevention and control, this article systematically elaborates on the precision local treatment for primary UM, the decision-making pathway for systemic treatment of metastatic UM based on molecular subtyping, the integration of local and systemic therapies for liver metastases, and the translational value of nanomedicine in addressing therapeutic bottlenecks. It provides insights for optimizing clinical management of mUM and developing novel therapeutic strategies.

Cancer multidrug resistance (MDR) impairs the therapeutic efficacy of various chemotherapeutics. Novel approaches, particularly the development of MDR reversal agents, are critically needed to address this challenge. This study demonstrates that tenacissoside I (TI), a compound isolated from Marsdenia tenacissima (Roxb.) Wight et Arn, traditionally used in clinical practice as an ethnic medicine for cancer treatment, exhibits significant MDR reversal effects in ABCB1-mediated MDR cancer cells. TI reversed the resistance of SW620/AD300 and KBV200 cells to doxorubicin (DOX) and paclitaxel (PAC) by downregulating ABCB1 expression and reducing ABCB1 drug transport function. Mechanistically, protein arginine methyltransferase 1 (PRMT1), whose expression correlates with poor prognosis and shows positive association with both ABCB1 and EGFR expressions in tumor tissues, was differentially expressed in TI-treated SW620/AD300 cells. SW620/AD300 and KBV200 cells exhibited elevated levels of EGFR asymmetric dimethylarginine (aDMA) and enhanced PRMT1-EGFR interaction compared to their parental cells. Moreover, TI-induced PRMT1 downregulation impaired PRMT1-mediated aDMA of EGFR, PRMT1-EGFR interaction, and EGFR downstream signaling in SW620/AD300 and KBV200 cells. These effects were significantly reversed by PRMT1 overexpression. Additionally, TI demonstrated resistance reversal to PAC in xenograft models without detectable toxicities. This study establishes TI's MDR reversal effect in ABCB1-mediated MDR human cancer cells through inhibition of PRMT1-mediated aDMA of EGFR, suggesting TI's potential as an MDR modulator for improving chemotherapy outcomes.

Objective:To explore the effect and mechanism of Chlorfortunone A(ChlA) in the treatment of diabetic nephropathy(DN) in mice.Methods:The DN model mice were assigned to DN, low-dose ChlA(ChlAL) and high-dose ChlA(ChlAH), and the normal control groups(Ctrl). Kidney tissue was analyzed via HE and Masson staining, and urine albumin, fasting blood glucose and kidney weight were measured. Collagen1 and α-SMA proteins were detected in renal tissues. The level of GSH-px, SOD, CAT, and TGF-β were detected. The TGF-β/Smad2 pathway in kidney tissue was detected. The mechanism was verified by setting the high glucose+ ChlA+ TGF-β group in MPC-5 cells. The proliferation of the cells and DCFDA staining were detected.Results:Compared to the Ctrl group, the DN group had significantly higher UACR and kidney weight( P<0.001). High-dose ChlA reduced UACR and kidney weight( P<0.05), with no effect on blood glucose( P>0.05). Masson staining showed reduced fibrosis with ChlA treatment. Collagen I and α-SMA expressions were significantly higher in DN( P<0.001) and decreased with ChlA treatment( P<0.05). GSH-px, SOD, and CAT levels were lower in DN( P<0.001), while TGF-β was elevated( P<0.001); ChlA increased antioxidant enzymes and decreased TGF-β( P<0.05). The TGF-β/Smad2 pathway was upregulated in DN( P<0.001) and inhibited by ChlA( P<0.001). In vitro, ChlA reduced cell proliferation( P<0.05) and increased ROS levels( P<0.001). Conclusions:ChlA alleviates kidney injury and fibrosis in DN mice, reduces oxidative stress, which may be related to the inhibition of the TGF-β/Smad2 pathway.

Coagulase-negative Staphylococci(CoNS)are a group of gram-positive cocci incapable of producing co-agulase,which distinguishes them from Staphylococcus aureus.CoNS are widely distributed in natural environ-ment and are commonly found on skin,mucous membranes and other host-associated tissues.In recent years,CoNS have become one of the significant pathogenic factors for hospital-associated infections and have been partic-ularly prevalent among the patients with impaired immune function.Although the pathogenicity of CoNS is gener-ally considered lower than that of coagulase-positive Staphylococci,the widespread use of implanted medical de-vices and extensive use of antibiotics has led to increasingly serious problems of drug resistance,which has atta-ched great importance to the hospital.The databases such as PubMed,Embase and CNKI were retrieved to reveal the drug resistance mechanisms of CoNS,aiming to push forward the research and development of new drugs against drug-resistant bacteria and emerging diagnosis and treatment measures and provide scientific bases for sol-ving the problems of antibiotics resistance around the globe.

OBJECTIVES:
To investigate the clinical application of the digital-assisted reconstruction of the mandible and tumors with free fibula transplantation and immediate implantation via the intraoral approach.
METHODS:
Twelve patients with benign mandibular tumors were collected. Three-dimensional mandibular reconstruction was performed digitally before surgery to simulate mandibular tumor resection, fibula resection and reconstruction, and implant implantation. The intraoperative resection of the mandibular tumor was conducted through the intraoral approach under the guidance of a guide plate, and fibula resection, molding, reconstruction, and oral fixation were immediately performed. Implant implantation was performed during the second phase of implant surgery and denture restoration was performed 1-2 months after surgery.
RESULTS:
The types of mandibular defects were BrownⅠ (one case), Ⅰc (four cases), Ⅱ (one case), Ⅱc(three cases), and Ⅲ (three cases). The length of the fibular bone was 12-22 cm. The number of fibular molding amputations was as follows: two cases in two segments, six cases in three segments, three cases in four segments, and one case in five segments. All of these cases underwent folding fibular reconstruction of mandibular and alveolar bone defects. A total of 44 implants were implanted, and none failed after operation.
CONCLUSIONS
The intraoral approach is a reliable method for the resection of mandibular benign tumors, with few postoperative complications and the ability to position and fix accurately the reconstructed folded fibula under digital design. The immediate implantation of the transplanted fibula does not affect the blood supply and has a high success rate. It is an effective and reliable method for the resection and reconstruction of mandibular benign tumors.

ObjectiveTo investigate the impact of metabolic associated fatty liver disease (MAFLD) on metabolic markers in patients with HIV infection, and to assess the risk of new-onset MAFLD in previously untreated HIV patients. MethodsA total of 161 HIV patients who attended the outpatient service of Zhongnan Hospital of Wuhan University from April 2020 to December 2021 were enrolled, and they were treated with the lamivudine/efavirenz/tenofovir disoproxil fumarate (3TC/EFV/TDF) regimen and were followed up for more than 36 months. According to the presence or absence of MAFLD, they were divided into MAFLD group with 42 patients and non-MAFLD group with 119 patients, and metabolic markers were compared between the two groups before and after treatment. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the paired t-test was used for comparison within each group before and after treatment; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Wilcoxon signed-rank test was used for comparison within each group before and after treatment; the chi-square test was used for comparison of categorical data between groups. Hepatic steatosis index (HIS) and Zhejiang University (ZJU) index were used to assess the risk of new-onset MAFLD after antiretroviral therapy. ResultsAfter 36 months of 3TC/EFV/TDF treatment, the MAFLD group had significant increases in body mass index (BMI) [24.8 (23.2 — 25.9) kg/m2 vs 25.3 (22.8 — 27.7) kg/m2, Z=-2.540, P=0.011], total cholesterol (TC) (4.0±0.6 mmol/L vs 4.3±0.6 mmol/L, t=-2.388, P=0.022), and high-density lipoprotein cholesterol (HDL-C) [0.9 (0.8 — 1.1) mmol/L vs 1.1 (0.9 — 1.2) mmol/L, Z=-2.858, P=0.004] and a significant reduction in serum uric acid (462.1±101.6 μmol/L vs 383.3±85.2 μmol/L, t=4.361, P<0.001). There was a significant difference in BMI between the MAFLD group and the non-MAFLD group after 3TC/EFV/TDF treatment [25.3 (22.8 — 27.7) kg/m2 vs 21.6 (19.9 — 23.4) kg/m2, Z=-5.462, P<0.001], while there were no significant differences between the two groups in serum uric acid, TC, triglyceride, HDL-C, low-density lipoprotein cholesterol, lipoprotein a, and CD4+ T cell count (all P >0.05). Furthermore, for the patients in the non-MAFLD group after treatment, there was a significant increase in the proportion of patients at a high risk of MAFLD based on HSI and ZJU indices (χ²=10.829 and 5.658, P=0.001 and 0.017). ConclusionAfter 36 months of 3TC/EFV/TDF treatment, there are increases in blood lipid levels in HIV patients with MAFLD, and there is an increase in the risk of new-onset MAFLD in HIV patients without MAFLD.

Objective:
To investigate the effects of usnic acid(UA) on proliferation, cell cycle, apoptosis and autophagy of lung cancer cells A549 and NCI-H358.
Methods:
The CCK-8 method was used to detect the inhibitory effect of UA on two kinds of lung cancer cells proliferation. Flow cytometry was used to detect the cell cycle arrest effect of UA on two types of lung cancer cells. The fluorescence amount of UA-induced reactive oxygen species(ROS) in two kinds of lung cancer cells were detected by DCFH-DA probe assay and flow cytometry. Western blot was used to detect the expression of apoptosis related proteins Bax, Caspase-3, Cleaved-Caspase-3, and autophagy related proteins LC3-Ⅰ and LC3-Ⅱ in two types of lung cancer cells after treatment with UA and UA+ROS inhibition.
Results:
(1) Usnic acid reduced the survival rates of two types of cells and had a stronger ability to inhibit the proliferation of A549 cells than NCI-H358 cells.(2) Usnic acid blocked A549 cells in the G0/G1phase, while NCI-H358 cells in the G2/M and S phases.(3) Usnic acid induced an increase in ROS content in two types of cells. Compared to A549, NCI-H358 cells showed a greater increase in ROS, and the ROS inhibitor reduced the intracellular ROS increase induced by UA.(4) Usnic acid induced high expression of apoptosis-related proteins Bax and Cleaved Caspase-3 and increased the ratio of autophagy-related proteins LC3-Ⅱ/LC3-Ⅰ in both lung adenocarcinoma cells, and its pro-apoptotic and autophagic effects were stronger in A549 than in NCI-H358. After ROS inhibition, the expression levels of Bax and Cleaved Caspase-3 and the LC3-Ⅱ/LC3-Ⅰ ratio of both lung adenocarcinoma cells decreased, and the decrease was greater in NCI-H358 cells.
Conclusion
Usnic acid inhibits the proliferation of lung cancer A549 and NCI-H358 cells, induces cell cycle arrest, and induces apoptosis and autophagy in cancer cells. The inhibitory and killing effect of UA on A549 cells is stronger than that on NCI-H358 cells. In this case, the induced cell ROS are involved in the action of UA in two types of lung cancer cells. In contrast to A549 cells,ROS might play a more significant role in mediating the apoptosis and autophagy induced by usnic acid in NCI-H358 cells.

Objective:To improve the understanding of recurrent adult Langerhans cell histiocytosis complicated with diabetes insipidus.Methods:The clinical data of 1 patient with recurrent adult Langerhans cell histiocytosis complicated with diabetes insipidus admitted to the First Affiliated Hospital of Shihezi University in January 2024 was collected. Its disease characteristics, effectiveness and safety of treatment scheme were analyzed, and literatures were reviewed.Results:The 42-year-old female patient was diagnosed as Langerhans cell histiocytosis in June 2021. After treated with cytarabine, the symptoms improved and the patient achieved sustained remission. In January 2024, the patient was admitted to the hospital due to pain in the middle part of the front chest. The PET-CT results indicated disease progression, which was manifested by new bone destruction, enlarged lymph nodes, and increased nocturnal urination, with urine volume of 3-5 L within 24 h. Based on the clinical manifestations such as cranial bone lesions, periorbital soft tissue lesions, and enlarged lymph nodes at onset, multiple systems and multiple foci involvement was considered. The diagnosis of combined diabetes insipidus was confirmed through the water deprivation and pressure test. After MACOP-B regimen (doxorubicin liposome, cyclophosphamide, vincristine, bleomycin, prednisone), the patient's bone pain was completely relieved, and no serious complications occurred.Conclusions:Recurrent adult Langerhans cell histiocytosis complicated with diabetes insipidus is rare; MACOP-B regimen is safe and effective in treatment of the disease.

Objective Depression,a most common psychiatric disease,is defined in Traditional Chinese Medicine(TCM)as Yu Syndrome,i.e.,depression disorder,or Baihe Disease,i.e.,lily bulb disease,a category of emotional disorders treated with lily-based TCM preparations.In TCM,depression is managed through syndrome differentiation and treatment,which is characterized by high efficacy and safety.However,there is no unified standard for the classification of depression syndromes,which leads to a disconnection between the analysis of patients'medication patterns and their actual syndromes and hinders the study of medication patterns specific to particular syndromes.Therefore,this study is focused on investigating the medication patterns of different sub-types of depression patients based on an objective classification system of depression.Methods We searched for and retrieved clinical literature on TCM formulas for depression from relevant databases,including China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP Database,Sinomed,Web of Science,and PubMed.Information on patient symptoms and medication was standardized.Then,the symptoms and the medication frequency of depression patients were statistically analyzed.We used the K-means clustering method combined with implicit structural analysis to objectively categorize depression patients into sub-types.In addition,the main symptoms and core TCM formulas of each sub-type of depression patients were identified.On the basis of objective classification system,we also statistically analyzed the characteristics of herbs used on depression patients,including the 4 basic properties,the 5 flavors,the attributes,the therapeutic efficacy,and the co-occurrence patterns,which may help reveal the medication patterns.Results A total of 3 537 publications and 4 434 prescriptions were included in the analysis.By using the K-means algorithm and latent structure analysis methods,patients with depression were categorized into 9 sub-types,with Cluster 6 accounting for the largest proportion.The most common symptoms among depression patients were insomnia and a depressed mood.Medication frequency analysis showed that Radix Bupleuri(Chai Hu),Radix Paeoniae Alba(Bai Shao),Poria(Fu Ling),Rhizoma Chuanxiong(Chuan Xiong),and Radix Curcumae(Yu Jin)were the most commonly used TCM herbs.For the depression sub-types of Clusters 1,2,and 6,blood-activating and stasis-dissolving herbs were used most often.The depression sub-types of Clusters 3,4,5,8,and 9 were mainly treated with qi-regulating herbs,while the depression sub-type of Cluster 7 was treated with qi-supplementing herbs.Depression patients were mostly treated with herbs that were cold or warm in nature and had sweet,bitter,and pungent flavors.Moreover,treatments for Cluster 1 and Cluster 6 mainly targeted the spleen meridian,while those for Cluster 2,Cluster 3,Cluster 4 and Cluster 5 mainly targeted the heart meridian.The treatments for the other sub-types mainly targeted the liver meridian.The core TCM formulas for the 9 depression sub-types included Zishui Qinggan Decoction,Danzhi Xiaoyao Powder,Huanglian Wendan Tang,Chaihu Guizhi Tang,Modified Xiaoyao Powder,Qinggan Jieyu Tang,Xiaoyao Powder,Xuefu Zhuyu Decoction,and Bazhen Decoction.The most commonly used Chinese herbal medicinal formulas were Gan Cao-Chai Hu,Bai Shao-Chai Hu,and Chen Pi-Chai Hu.Conclusion Based on machine learning,this study reveals the scientific aspects of TCM typing and syndrome-based treatment.It clarifies the rationale for targeting different symptoms in depression treatment and provides theoretical support for clinicians to make medication prescriptions.It also presents a new perspective for investigating TCM medication patterns.
