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.

ObjectiveStarting from the etiology， pathogenesis， and treatment strategies of endometriosis and adenomyosis， to integrate and sort out the academic characteristics of contemporary renowned experts and schools in the field of traditional Chinese medicine gynecology. MethodsAccording to the systematic review of text and opinion （SrTO） process developed by the Joanna Briggs Institute （JBI） in Australia， this paper determined literature screening criteria by searching China National Knowledge Infrastructure （CNKI）， VIP， Wanfang， and China Biomedical Literature Database. Information was extracted after literature screening， and quality evaluation was conducted using the JBI Narrative， Text， and Opinion Systematic Review Strict Evaluation Checklist. The JBI Narrative， Opinion， Text Evaluation， and Review Tool Summary Table was used for information synthesis， and data analysis and display were conducted in the form of text and charts. ResultsThe 146 articles related to 39 renowned experts and 19 articles related to 10 schools of thought were included. Research has found that contemporary experts and schools in traditional Chinese medicine gynecology consider blood stasis as the core pathogenesis in understanding the etiology and pathogenesis of two diseases and related infertility. Their viewpoints varied from multiple aspects such as clinical symptom characteristics， meridian circulation location， pathological product evolution， disease duration， emotional psychology， lifestyle habits， preference for food and drink， innate endowment， and acquired injury. In terms of treatment， it was advocated to divide the stage， treat according to different types， adapt to the times， integrate nature and humans， and combine multiple methods to treat comprehensively when necessary. It was also recommended to skillfully use insects， make good use of classic formulas and small prescriptions， pay attention to protecting the spleen and stomach and regulating emotions， and make good use of self-formulated empirical formulas for internal or external use. Besides， individualized long-term management of patients was also advocated. ConclusionThis study applies the SrTO process to systematically summarize the academic ideas of contemporary renowned experts and schools in traditional Chinese medicine gynecology regarding the causes， mechanisms， diagnosis， and treatments of endometriosis， providing a scientific and standardized reference for future theoretical exploration.

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.

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.

Objective To explore the predictive value of combined serum soluble hemoglobin scavenger receptor 163(sCD163),hypersensitive C-reactive protein(hs-CRP),and procalcitonin(PCT)for stroke-associated pneumonia(SAP).Methods A total of 100 patients with acute ische-mic stroke admitted to the First Hospital of Zhangjiakou from October 2021 to January 2023 were se-lected as the study subjects.According to whether they developed SPA within 7 days of admission,they were divided into SAP group(n=64)and non-SAP group(n=36).Based on pneumonia se-verity index(PSI),patients in the SAP group were further divided into mild SAP group and severe SAP group.Enzyme-linked immunosorbent assay(ELISA)was used to detect the serum levels of sCD163,hs-CRP,and PCT.The clinical data of the patients were collected and compared.Pearson's method was used to analyze the correlation between the PSI score and the serum levels of sCD163,hs-CRP,and PCT in SAP patients.Multivariate Logistic regression analysis was employed to screen for factors influencing the occurrence of SAP.Receiver operating characteristic(ROC)curve analy-sis was used to evaluate the predictive efficacy of serum sCD163,hs-CRP,and PCT for the occur-rence of SAP.Results The proportion of patients with dysphagia and the National Institutes of Health Stroke Scale(NIHSS)score in the SAP group were significantly higher than those in the non-SAP group(P＜0.05).The serum levels of sCD163,hs-CRP,and PCT in the SAP group were significantly higher than those in the non-SAP group(P＜0.05).The serum levels of sCD163,hs-CRP,and PCT in the severe SAP group were significantly higher than those in the mild SAP group(P＜0.05).Pearson's correlation analysis showed that the PSI score was positively correlated with the serum levels of sCD163,hs-CRP and PCT in SAP patients(r=0.356,0.413,0.391,P＜0.001).Logistic regression analysis revealed that serum sCD163,hs-CRP,PCT,NIHSS score,and dysphagia were all influencing factors for the occurrence of SAP(P＜0.05).The areas under the curve(AUC)for predicting SAP using serum sCD163,hs-CRP,PCT and their combina-tion were 0.842,0.924,0.866 and 0.973,respectively,with sensitivities of 73.44％,84.37％,67.19％and 90.62％,and specificities of 88.89％,83.33％,97.22％and 94.44％,respectively.The predictive value of the combined detection was superior to that of the individual detection of ser-um sCD163,hs-CRP and PCT(P＜0.05).Conclusion The serum levels of sCD163,hs-CRP,and PCT are elevated in SAP patients,and their changes are closely related to the severity of the disease.The combined detection of these three indicators has a high value in predicting the occur-rence of SAP and may serve as auxiliary markers for predicting early SAP.

Objective To compare the efficacy of trastuzumab plus pertuzumab(HP)combined with either nab-paclitaxel plus carboplatin or docetaxel plus carboplatin as neoadjuvant therapy for HER2-positive breast cancer in real-world clinical practice.Methods Clinical data of HER2-positive breast cancer patients who received neoadjuvant therapy with either HP combined with nab-paclitaxel plus carboplatin or HP combined with docetaxel plus carboplatin and subsequently underwent surgery were retrospectively collected from 11 tertiary grade-A hospitals in Hebei Province from June 2019 to December 2021.The total pathological complete response(tpCR)rates of the two groups were compared.Results A total of 76 patients were included in the study,with 47 in the nab-paclitaxel group and 29 in the docetaxel group.The tpCR rate was significantly higher in the nab-paclitaxel group than that in the docetaxel group(72.3%vs.48.3%,χ2=4.463,P=0.035).Subgroup analysis indicated that patients older than 40 years,with cN2-3,cTNM stage Ⅲ,hormone receptor-positive status,and Ki67>30%had significantly higher tpCR rates in the nab-paclitaxel group than those in the docetaxel group(P<0.05).Conclusion In real-world clinical practice,the efficacy of HP combined with nab-paclitaxel plus carboplatin as neoadjuvant therapy for HER2-positive breast cancer is superior to that of HP combined with docetaxel plus carboplatin.
