Objective To investigate the prognostic value of optic nerve sheath diameter(ONSD)measured by critical care ultrasound combined with serum biomarkers[S100 calcium-binding protein β(S100β)and neuron-specific enolase(NSE)]in patients with severe traumatic brain injury.Methods A total of 103 adult severe traumatic brain injury patients admitted to the intensive care unit of this hospital from A-pril 1,2023,to April 1,2024 were enrolled.All patients underwent invasive intracranial pressure monitoring after admission,alongside bedside critical care ultrasound measurement of ONSD at 3 mm behind the globe and serum biomarker testing.Baseline data and Glasgow outcome scale(GOS)scores at 90 days after dis-charge were recorded.Patients were divided into the survival and the non-survival groups based on GOS scores.Receiver operating characteristic(ROC)curve analysis and area under the curve(AUC)were used to evaluate the predictive performance of ONSD and serum biomarkers for poor prognosis in severe traumatic brain injury patients.Results Ninety-six patients were ultimately included,with 52(54.1％)in the survival group and 44(45.9％)in the non-survival group.Significant differences were observed in blood glucose,Glas-gow coma scale(GCS)score,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score,ONSD,NSE,and S100β levels(P＜0.05)between the two groups.Multivariate analysis identified ONSD(OR=4.962,95％CI:3.473-6.254),NSE(OR=2.704,95％CI:1.987-3.033),S100β(OR=2.983,95％CI:1.843-4.571),and APACHE Ⅱ score(OR=3.726,95％CI:2.837-4.592)as independent predictors of mortality in severe traumatic brain injury patients(P＜0.05).The combination of ONSD,NSE,and S100β yielded an AUC of 0.840 for predicting poor prognosis,with a specificity of 88.3％and sensitivity of 98.6％.Conclusion ONSD and serum brain injury biomarkers(NSE,S100β)are associated with in-hospital prognosis in severe traumatic brain injury patients.Their combined detection can effectively predict a poor outcome.

Inflammation is involved in the development of various acute and chronic diseases in the body. Sustained inflammatory responses are key driving factors for diseases such as cancer， neurodegenerative diseases， cardiovascular diseases， metabolic syndrome， inflammatory bowel disease， and arthritis. Therefore， finding anti-inflammatory drugs is crucial for the prevention and treatment of various diseases. In recent years， there has been increasing attention to finding natural drugs with minimal toxic side effects. Lonicerae Japonicae Flos and Lonicerae Flos， as traditional Chinese medicines potent in clearing heat and removing toxins， have strong biological activity and multiple pharmacological effects. They are widely distributed in the plant world and have significant medicinal value. With the continuous advancement of the research on Lonicerae Japonicae Flos and Lonicerae Flos， they have been widely used in the medical field and possess great development potential. Currently， research mainly focuses on the anti-inflammatory mechanisms of Lonicerae Japonicae Flos and Lonicerae Flos， while systematic summaries of their anti-inflammatory active ingredients are rare. Therefore， this paper focuses on the differential analysis of the anti-inflammatory active components of Lonicerae Japonicae Flos and Lonicerae Flos. In addition， it reviewed the possible mechanisms by which extracts and active ingredients of Lonicerae Japonicae Flos and Lonicerae Flos may exert anti-inflammatory effects through various pathways， such as influencing the release of cellular inflammatory factors， regulating inflammatory signaling pathways such as nuclear factor-κB （NF-κB）， mitogen-activated protein kinase （MAPK）， signal transducer and activator of transcription 3 （STAT3）， MAPK/extracellular signal-regulated kinase （ERK）/c-Jun N-terminal kinase （JNK）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/NF-κB， and Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathways， increasing antioxidant stress capacity， enhancing immune defense capabilities， and improving intestinal microbiota， aiming to provide a theoretical basis for the rational clinical application of Lonicerae Japonicae Flos and Lonicerae Flos.

Basic research and interdisciplinary application of traditional Chinese medicine （TCM） have been continuously extended and rapidly developed with the continuous funding and promotion of basic research on TCM supported by the National Natural Science Foundation of China （NSFC）， and the overall level of basic research on TCM has been significantly improved， which has made important contributions to the diagnosis and treatment mechanism of TCM by "clarifying， identifying， and interpreting"， providing benchmark guarantees for basic research and industry development of TCM. This article focused on the application and funded projects of NSFC in 2023 under the H31 application code of TCM. It analyzed the project types， branch codes， research question categories， supporting units and regions， research directions， and keywords and summarized the characteristics of the currently funded projects in H31. At the same time， it analyzed the relevant problems in the project application process and put forward several suggestions， so as to provide a reference for scholars in the field of TCM. In 2023， a total of 8 334 applications for three types of projects （general projects， projects for young scholars， and regional projects） under the H31 code have been received by NSFC， which is the highest number in the past five years. However， the proportion of funding is still on a downward trend， and there is fierce competition among applicants. Finally， 804 projects for the three categories under the H31 code have been funded. The total funding decreased in 2022， and the average funding amount of the general project and the regional project has dropped to the lowest in the past five years. It is found that the development of branch research and the research questions under the H31 code is unbalanced. Few projects have focused on the original theory of TCM. Some projects are detached from the characteristics and research laws of TCM. Most researchers lack innovative research ideas， and the applications they write are filled with routines and patterns. In addition， the issue of scientific integrity remains a primary principle for project applicants.

Objective:To analyze the clinical characteristics and influencing factors of vascular involvement in Beh?et′s Disease (BD) to improve and provideunderstanding of insights for clinicians to better understand this condition.Methods:Clinical data from 220 BD patients admitted to the First Affiliated Hospital of Guangxi Medical University from January 2012 to May 2022 were collected. Clinical manifestations and laboratory findings were compared between BD patients with and without vascular involvement, as well as between those with improved conditions and those with progressive conditions. Binary logistic regression was used to analyze the influencing factors.Results:①The average age of the 220 BD patients was 36.5±15.3 years. Among them, 23 patients (10.5%) had vascular involvement, including 20 males (87.0%).②Compared to BD patients without vascular involvement, those with vascular involvement had significantly higher rates of smoking [6.1%(12/197) vs.34.8%(8/23), χ2=17.19, P<0.001], cardiac involvement [1.5%(3/197) vs. 13.0%(9/23), χ2=6.42, P=0.011], and elevated C-reactive protein(CRP) levels (78.3% vs. 56.3%, χ2=4.08, P=0.043).③ Among BD patients with vascular involvement, 11 cases (47.8%) had venous lesions, and 20 cases (87.0%) had arterial lesions, with 8 cases (34.8%) having both venous and arterial involvement. The most common type of vascular involvement was arterial dilatation (11 cases), mainly aneurysms (10 cases), and deep venous thrombosis of the lower extremities (7 cases).④The 23 BD patients with vascular involvement were followed up for an average of 18.3 months. Among them, 16 patients (69.6%) showed stable improvement, while 7 patients (30.4%) experienced disease progression, including 4 deaths (1 male and 3 females). A total of 91.3% (21/23) of the patients received glucocorticoid therapy. Immunosuppressive therapy was administered to 82.6% (19/23) of the patients, with 65.2% (10/23) receiving with cyclophosphamide and 43.5% receiving with thalidomide. Additionally, 13% (3/23) of the patients were treated with cyclosporine and methotrexate, respectively, and 8.7% (2/23) were treated with received mycophenolate mofetil. Anticoagulant therapy was given to 21.7% (5/23) of the patients, using either warfarin or low molecular weight heparin. Biologic therapy was administered to 17.4% (4/23) of the patients, and surgical intervention was performed in 43.5% (10/23) of the patients. ⑤Binary logistic regression analysis identified male gender [ OR(95% CI)=5.70(1.60, 20.90), P=0.009] as an indepe-ndent risk factor for vascular involvement in BD. Conclusion:The incidence of vascular involvement in BD is 10.5%, with a higher prevalence in males. Arterial involvement is more common than venous involvement, with arterial aneurysms being the most common manifestation. Clinicians should pay attention to CRP and total cholesterol levels in BD patients.

ObjectiveTo explore the mechanism of Gancao Fuzitang （GCFZ）in inhibiting the bone destruction of collagen-induced arthritis （CIA） model in mice. MethodThirty male DBa/1J mice were randomly divided into normal group， CIA group， low-dose GCFZ group （GCFZ-L， 2.4 g·kg^-1）， high-dose GCFZ group （GCFZ-H， 4.8 g·kg^-1）， and methotrexate group （MTX， 1 mg·kg^-1）， with six mice in each group. The CIA model was induced by secondary immunization method. The arthritis index of mice in each group was observed and recorded， and the histopathological changes in ankle joint were observed by hematoxylin-eosin （HE） staining. The damage to ankle cartilage was detected by safranin O-fast green staining. Micro-CT scanning was used to detect the bone destruction of ankle joint， and the expression of nuclear factor-κB p65 （NF-κB p65）， p-NF-κB p65， inhibitory-κB kinase α/β （IKKα/β）， and p-IKKα/β was observed by immunohistochemical staining. ResultCompared with the normal group， the CIA group showed manifest joint swelling and increased arthritis index score （P<0.01）. Compared with the CIA group， the groups with drug intervention could inhibit joint swelling and reduce arthritis index score （P<0.05， P<0.01）. As revealed by HE staining and safranine O-green staining， compared with the CIA group， the groups with drug intervention could inhibit synovial invasion and reduce the destruction of articular cartilage. Micro-CT scanning analysis showed that compared with the CIA group， the GCFZ-H group and the MTX group showed reduced bone destruction scores （P<0.01）. The immunohistochemical results showed that compared with the normal group， the CIA group showed increased optical density values of NF-κB p65， p-NF-κB p65， IKKα/β， and p-IKKα/β（P<0.01）. Compared with the CIA group， the GCFZ-H group and the MTX group showed reduced optical density values of NF-κB p65， p-NF-κB p65， IKKα/β， and p-IKKα/β（P<0.05，P<0.01）. In the GCFZ-L group， only the NF-κB p65 optical density value decreased（P<0.01）. ConclusionGCFZ may inhibit bone destruction in CIA mice by regulating the NF-κB signaling pathway.

Objective:To study the effect of matrine on the expression of transcription factor Snail2 in peritoneal mesothelial cells epithelial-mesenchymal transition (EMT) induced by transforming growth factor-β1 (TGF-β1).Methods:Human peritoneal mesothelial cells were stimulated by TGF-β1 and treated with matrine. The experiment was divided into six groups (control group, TGF-β1-induced group (5 ng/ml), TGF-β1+0.4 mg/ml matrine intervention group, TGF-β1+0.6 mg/ml matrine intervention group, TGF-β1+0.8 mg/ml matrine intervention group and TGF-β1+1.0 mg/ml matrine intervention group). The expressions of Snail2, E-cadherin, α-smooth muscle actin (α-SMA), Fibronectin and collagen (Col)Ⅲ were detected by real-time fluorescence quantitative PCR and Western blotting. The protein phosphorylation levels of Smad2, Smad3 and extracellular signal-regulated kinase (ERK)1/2 were detected by Western blotting.Results:The mRNA and protein expressions of Snail2, α-SMA, Fibronectin and ColⅢ were up-regulated after being stimulated by TGF-β1 (5 ng/ml) in human peritoneal mesothelial cells, while the mRNA and protein expression of E-cadherin was down-regulated. TGF-β1 (5 ng/ml) could up-regulate the protein phosphorylation levels of Smad2, Smad3 and ERK1/2. Matrine (0.4, 0.6, 0.8, 1.0 mg/ml) could down-regulate the mRNA and protein expression levels of Snail2, α-SMA, Fibronectin and ColⅢ after being stimulated by TGF-β1 in human peritoneal mesothelial cells. Matrine could down-regulate the protein phosphorylation of ERK1/2, and up-regulate the mRNA and protein expression levels of E-cadherin with treatment of TGF-β1 in human peritoneal mesothelial cells.Conclusions:TGF-β1 can induce EMT of human peritoneal mesothelial cells. Matrine may inhibit TGF-β1-induced EMT of human peritoneal mesothelial cells by down-regulating the expression of Snail2 through the ERK1/2 signaling pathway.
