Vascular smooth muscle cells (VSMCs) proliferation is the critical pathological process of in-stent restenosis (ISR). Recent researches indicate that the traditional Chinese medicine curcuma zedoary (E’zhu) can inhibit VSMCs proliferation, with a potential value in preventing and treating ISR. The major ac-tive components of curcuma zedoary are curcuma and β-elemene. The underlying mechanisms involve the inhibition of hemeoxygen-ase-1 expression, blockade of extracellular signal-regulated ki-nase – MAPK and Akt pathways, and subsequent cell cycle ar-rest. This article reviews the recent progress on curcuma zedoary extracts regulating VSMCs proliferation in ISR.

Objective:To investigate the CT features of lung injury induced by paraquat poisoning and its relationship with prognosis, and to provide reference for the judgment of the condition and prognosis of paraquat poisoning.Methods:146 cases of paraquat poisoning patients were treated in the Third People's Hospital of Xuzhou City from January 2013 to April 2016. The cases were divided into mild group, moderate-severe group and fulminant group according to the concentration of paraquat in urine. The clinical data and CT imaging findings were analyzed and reconstructed in three-dimensional reconstruction. The extent of the lesion was observed and the relationship between CT and prognosis was explored.Results:Paraquat lung injury has many manifestations on CT images, and it's performance can be intersecting at the same time. Early lesions lighter cases, late CT imaging lesions can be completely absorbed or residual fibrosis, the prognosis was good; the early lesion was pulmonary consolidation, pleural effusion cases, the late CT image was usually pleural thickening and bronchiectasis, the prognosis was relatively good; early lesions were large patches of ground glass opacity cases, finally, pulmonary fibrosis was common, the mortality rate of 56.57%. There were significant differences in the extent of lung injury between different groups ( P<0.001) , and the difference in mortality was statistically significant when the lung injury was different ( P<0.001) . Multivariate stepwise Logistic regression analysis showed that ground-glass opacity ( OR value=2.013) , interstitial lung fibrosis ( OR=3.779) and mediastinal emphysema ( OR=33.118) were risk factors for death of lung injury caused by paraquat poisoning ( P<0.05) . Conclusion:There were many manifestations on CT images of paraquat lung injury, and the manifestations of paraquat lung injury can be intersecting at the same time. The pulmonary manifestations and outcomes of different paraquat types were different. The CT manifestations of lung injury in paraquat poisoning were mainly exudative changes at early stage, and can be gradually absorbed or evolved into interstitial changes at later stage. The cumulative damage range can be used as a reference for evaluating the prognosis. Ground-glass opacity, interstitial pulmonary fibrosis and mediastinal emphysema are the risk factors for death of lung injury caused by paraquat poisoning.

【Objective】 To investigate the correlation between perioperative zero red blood cell(RBC) transfusion and the prognosis of patients with acute Stanford type A aortic dissection. 【Methods】 A retrospective analysis was made on 96 patients who underwent one-stop Hybrid surgery for acute Stanford type A aortic dissection in our hospital from May 2021 to May 2022. The patients were divided into two groups according to whether they received perioperative RBC transfusion: zero RBC transfusion group (group A, n=26) and RBC transfusion group (group B, n=70). The preoperative general data and laboratory indexes were recorded and the propensity score matching method was used to screen the patients with the same preoperative baseline data, with comparison of operation-related indicators, intraoperative and postoperative blood component dosage and prognostic indicators. 【Results】 With BMI index, hemoglobin, platelet count, and troponin T as co variables, 48 patients were included in the study after matching according to 1∶1 propensity score: Group A (n=24) and Group B (n=24). Compared with group A, hemoglobin and hematocrit in group B decreased significantly at the end of operation and 24 h after operation, with a statistically significant difference (P<0.05). There was no significant difference between the two groups in operation-related indicators, intraoperative and postoperative blood component dosage, in-hospital mortality, continuous renal replacement therapy, incidence of infection and cerebral infarction (P>0.05). 【Conclusion】 The perioperative hemoglobin of patients with acute Stanford type A aortic dissection with zero RBC transfusion did not significantly decrease, and the postoperative complications and mortality did not increase.

Objective:To explore the active ingredients of shengxian and jinshuiliujun decoction with the method of network pharmacology, and to verify the experimental mechanism of its treatment of silicosis.Methods:In May 2023, the active ingredients and targets of drugs in shengxian and jinshuiliujun decoction were obtained through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database. The target of silicosis disease was screened by databases such as Genecards, Disease Gene Network (DisGeNET), Comparative Toxicogenomics Database (CTD), etc. The screened drug targets and disease targets were intersected to obtain the target set of shengxian and jinshuiliujun decoction for the treatment of silicosis. Protein-protein interaction (PPI) network analysis was performed on the target set through STRING database, and core target genes were screened. GO enrichment analysis and KEGG pathway analysis of intersection genes were performed based on Metascape database, and molecular docking verification of key components and targets of shengxian and jinshuiliujun decoction was carried out. Twenty-four adult male SD rats with SPF grade were randomly divided into control group, model group and TCM intervention group, with 8 rats in each group. The dust-stained rat model was prepared by non-tracheal exposure of 1 ml silica suspension (50 mg/ml) in one go, and TCM intervention group was given shengxian and jinshuiliujun decoction[6 g/ (kg·d) ] on the second day. The CT of the lungs of each group was observed 28 days after the dust-stained rat model. Paraffin sections of rat lung tissues were prepared and stained with Hematoxylin-Eosin (HE) and Masson. Western blot was used to verify the expression of core target-related proteins in rat lung tissues after the intervention of shengxian and jinshuiliujun decoction for 28 days, and the differences in protein expression between groups were compared by one-way analysis of variance.Results:A total of 205 active ingredients and 3345 active compounds were selected from shengxian and jinshuiliujun decoction, corresponding to 281 targets, among which 240 targets were related to silicosis. Serine/threonine kinase 1 (AKT1), tumor protein p53 (TP53), tumor necrosis factor (TNF) and interleukin (IL) 6 may be the key targets of shengxian and jinshuiliujun decoction in the treatment of silicosis. Through enrichment analysis, 30 GO entries and 20 potential signaling pathways were screened according to P-value, including nuclear factor κB (NF-κB), mitogen-activated protein kinase (MAPK) and cancer signaling pathways. Molecular docking showed that the active compounds of shengxian and jinshuiliujun decoction had good binding with the core target proteins, and the strongest binding properties were beta-sitosterol and TNF-α (-10.45 kcal/mol). In animal experiments, the inflammatory infiltration and fibrosis of lung tissue of rats in TCM intervention group were significantly improved. Compared with control group, the levels of TNF-α, IL-1β, IL-6 and NF-κB in lung tissue of model group were significantly increased ( P<0.05). Compared with model group, the lung injury of rats in TCM intervention group was significantly improved, and the expressions of TNF-α, IL-1β, IL-6 and NF-κB were significantly decreased ( P<0.05) . Conclusion:Shengxian and jinshuiliujun decoction in the treatment of silicosis may play an anti-fibrosis role by inhibiting the NF-κB signal transduction pathway mediated by inflammatory factors such as TNF-α and IL-1β, which provides a reference for further exploring the material basis and mechanism of its action.
