Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

Objectives:We aimed to compare the impact of dissection and re-entry(DR)recanalizing pattern with non-DR on the in-hospital results and prognostic outcomes of patients treated successfully by percutaneous coronary intervention(PCI)of chronic total occlusion(CTO)and examine the benefit of DR in CTO PCI. Methods:A total of 815 consecutive patients with CTO meeting the inclusion criteria in the Department of Cardiology of the First Affiliated Hospital of PLA Air Force Military Medical University from January 2018 to December 2020 were enrolled and divided into DR group(n=239)and non-DR group(n=576)according to whether DR recanalizing pattern was used in the procedure.The clinical characteristics,coronary angiographic characteristics,procedure results,and complications were collected,and the prognostic outcomes within one year after the procedure were observed.Propensity score matching by the clinical and coronary angiographic characteristics was performed and results were compared with 208 matched patients in each group.The endpoints were the major adverse cardiovascular events(MACE)consisting of all-cause death and myocardial infarction,clinically driven target vessel revascularization(TVR)one year after the procedure,and in-hospital outcomes. Results:The mean age of all patients was(60.9±10.9)years old,and 87.4%were male.As compared with the non-DR group,the proportion of blunt cap,ambiguous,calcification,angle＞45°,and diseased landing zone,as well as mean J-CTO score was higher in the DR group(all P＜0.05).The mean stent length and median procedure time were longer in the DR group,median guidewires and consumed contrast volume was also higher in the DR group(all P＜0.001).Incidence of in-hospital death,myocardial infarction,perforation,side branch loss,bleeding of BARC 3rd grade and above,and contrast-related impairment of renal function were similar between the two groups(all P＞0.05).However,peripheral vascular complications occurred more frequently in the DR group(P=0.007).One year after the procedure,the incidence of MACE(2.9%vs.2.4%,log-rank P=0.750)and clinically driven TVR(5.8%vs.3.9%,log-rank P=0.365)as well as all-cause death(2.9%vs.1.0%,log-rank P=0.154)and myocardial infarction(0.5%vs.1.9%,log-rank P=0.184)were similar between the two matched groups.Multivariate Cox regression analysis showed no significant association between DR and MACE(HR=1.129,95%CI:0.427-2.979,P=0.807)and TVR(HR=0.606,95%CI:0.213-1.722,P=0.347).LVEF≤40%(HR=2.775,95%CI:1.137-6.774,P=0.025)and elevated residual SYNTAX score(HR=1.089,95%CI:1.032-1.150,P=0.002)were risk factors for MACE,and diseased landing zone(HR=2.144,95%CI:1.019-4.513,P=0.045),rescued ADR(HR=3.479,95%CI:1.109-10.919,P=0.033),and prolonged procedure time(HR=1.007,95%CI:1.002-1.013,P=0.007)were risk factors for TVR. Conclusions:CTO lesion recanalized with PCI utilizing DR operation pattern was associated with more complex characteristics,more devices and time consumed,and longer stent length,while no significant association was observed between DR operation pattern and MACE and TVR one year after the procedure,as well as in-hospital complication..

An integrated evaluation model based on the combination of traditional trait identification and modern chemical analysis was used for the identification of key indexes of grade classification and the establishment of grade quality standard of Lycium barbarum fruits (LBF) from Ningxia genuine producing area. Under the guidance of herbal examination and market survey, particle size, skin color and imperfection were taken as the external trait indicators; focusing on the comprehensiveness and validity of the quality evaluation, 2-O-β-D-glucopyranosyl-L-ascorbic acid (AA-2βG), zeaxanthin dipalmitate (ZD) and volatile ether extractives were used as important parameters involving in quality evaluation in addition to the pharmacopoeia test items and determination indicators such as moisture, ash, water-soluble extractives, Lycium barbarum polysaccharide (LBP) and betaine. The quality differences between different traits and grades of LBF as well as the relevance between character and quality were further investigated by mathematical and statistical means such as t-test analysis, correlation analysis and principal component analysis (PCA). Furthermore, the activities of extractives from different grades of LBF were compared at cellular level. The results showed that LBF were mainly preferred for large and red ones; except for betaine, the other index components were relatively high (moisture and ash were low) in the first-grade and samples with bright-red skin color. Besides, there was a significant correlation between skin color and moisture, water-soluble extractives, LBP, AA-2βG and ZD contents. Considering the results of the study and the market situation, the present study took the grain size and skin color of LBF as the core of evaluation, and at the same time introduced the multi-indicator components including LBP, AA-2βG, ZD, water-soluble extractives and moisture to further guide the grading, and established the quality standard of LBF grades combining the trait indexes and the chemical composition. More importantly, in vitro cell models both preliminarily confirmed that the first-grade LBF played a more significant "nourishing liver and kidney" effect, which provided an experimental basis for the quality control of LBF and promoted the realization of high quality and good price.

On the basis of the qualitative preparation quality markers of Zhibao Sanbian Wan (ZBSBW), we screened out the quantitative markers and evaluated the content consistency of ZBSBW. A method capable of simultaneously determining 34 compounds in ZBSBW was established based on HPLC-MS/MS, and 16 batches of ZBSBW were simultaneously analyzed by this method. Furthermore, we explored a general strategy for analyzing the component migration in preparation, plasma, brain tissue and cerebrospinal fluid. The methodological investigation was confirmed by linear range, recovery (85.10%-105.07%), precision (RSD: 1.37%-4.58%), stability, and repeatability (3.00%-12.45%), the established method was suitable for the detection and quantification of the compounds in ZBSBW. The contents of compounds in ZBSBW were all lower than 1 mg·g^-1, and the contents and daily dose of nystose were the highest, followed by echinacoside, paeoniflorin, osthole and paeonol. The results of systematic clustering showed that the contents were consistent for ordinary preparations of ZBSBW. The principal component analysis showed that the components of berberine, ginsenoside Re, ginsenoside Rg1, pinoresinol diglucoside and tenuifolin had large variation, which contributed significantly to the grouping. The contents of echinacoside, verbascoside, polygalaxanthone Ⅲ, β-ecdysterone, osthole, alisol B 23-acetate, liquiritin and glycyrrhizic acid were stable from batch to batch. The animal experiment results showed that osthole, paeonol and liquiritin in ZBSBW could be absorbed into the blood and enter the brain tissue by passing through the blood-brain barrier. All animal studies were reviewed and approved by the Institutional Animal Care and Use Committee at Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences (No. 2020B071). The above compounds contributed the quantitative preparation quality markers of ZBSBW. In conclusion, the HPLC-MS/MS method established in this study was sensitive, accurate and rapid, and could be used for simultaneous quantification of 34 compounds and content consistency evaluation of multiple batches of preparations in ZBSBW. The result provided a methodological basis for the screening of quantitative preparation quality markers and material basis research of ZBSBW.

【Objective】 To explore a new treatment of primary bilateral macronodular adrenal hyperplasia (PBMAH) and its efficacy. 【Methods】 Clinical data of 20 PBMAH patients treated in our hospital during Mar.2010 and Apr.2021 were retrospectively analyzed. All patients underwent laparoscopic subcutaneous displacement of vascularized adrenal. The clinical symptoms, plasma free cortisol, adrenocorticotrophic hormone (ACTH), and 24 h urinary free cortisol were regularly monitored after surgery. 【Results】 Of all 20 patients, 19 were followed up for 18 to 120 months (median 60 months). Three months after surgery, reexamination showed 1 patient had decreased plasma free cortisol and increased ACTH, but had no symptoms of low corticosteroids. After another 3 months, the plasma free cortisol and ACTH returned to normal. After 4 to 48 months, the parameters recovered in all patients and the clinical symptoms disappeared. 【Conclusion】 Laparoscopic vascularized adrenal displacement is a new and effective method for the treatment of PBMAH. It can alleviate the Cushing syndrome with no obvious adverse reactions.
