Objective To explore the application effect of prone position ventilation combined with veno-venous extracorporeal membrane oxygenation (VV-ECMO) in the treatment of severe primary graft dysfunction (PGD) after lung transplantation. Methods The clinical data of 75 lung transplant recipients who developed severe PGD after lung transplantation and were treated with VV-ECMO from January 2021 to June 2024 at Wuxi People's Hospital Affiliated to Nanjing Medical University were collected. The patients with severe graft dysfunction after lung transplantation were divided into VV-ECMO group (control group, 45 cases) and prone position ventilation combined with VV-ECMO group (treatment group, 30 cases). The general data of the two groups of patients were compared, including the donors' clinical data (age, gender and oxygenation index, etc) and the recipients' clinical data [gender, age and body mass index (BMI), etc]. Cox regression analysis was used to analyze the influencing factors of the recipients' 30-day, 90-day and 180-day survival after surgery. The survival curves of the two groups of recipients were drawn using Kaplan-Meier method and compared using the log-rank test. Results The intensive care unit (ICU) stay time, ECMO application time and ventilator use time of control group were longer than those of treatment group. The proportion of male recipients and the BMI of control group were lower than those of treatment group. The 30-day, 90-day and 180-day survival of control group was worse than that of treatment group, and the differences were statistically significant (all P<0.05). The univariate Cox regression analysis of the recipients' 30-day survival after surgery showed that the recipients' BMI, history of diabetes, enlargement of the right atrium and right ventricle, intraoperative blood transfusion volume and intraoperative red blood cell transfusion volume were statistically significant (all P<0.05). The multivariate Cox regression analysis showed that the history of diabetes and enlargement of the right atrium and right ventricle were risk factors affecting the 30-day survival of lung transplant recipients (all P<0.05). The univariate Cox regression analysis of the recipients' 90-day survival after surgery showed that the recipients' BMI, history of diabetes, enlargement of the right atrium and right ventricle, intraoperative blood transfusion volume, intraoperative red blood cell transfusion volume and group variable were statistically significant (all P<0.05). The multivariate Cox regression analysis showed that the history of diabetes, enlargement of the right atrium and right ventricle and group variable were risk factors affecting the 90-day survival of lung transplant recipients (all P<0.05). The univariate Cox regression analysis of the recipients' 180-day survival after surgery showed that the recipients' BMI, history of diabetes, right atrium and right ventricle enlargement, intraoperative blood transfusion volume, intraoperative red blood cell transfusion volume and group variable were statistically significant (all P<0.05). The multivariate Cox regression analysis showed that the history of diabetes, enlargement of the right atrium and right ventricle and group variable were risk factors affecting the 180-day survival of lung transplant recipients (all P<0.05). The 30-day, 90-day and 180-day survival rates of control group were lower, and the differences between the two groups were statistically significant (all P<0.05), with a median survival time of 100 days in control group. Conclusions In the clinical treatment of severe PGD after lung transplantation, prone position ventilation combined with VV-ECMO may shorten ECMO application time, invasive ventilation time and ICU stay time, and improve the short-term prognosis of lung transplantation.

ObjectiveTo evaluate the effect and safety of Jiuxin Pill （救心丸） on exercise tolerance and quality of life in patients with stable angina pectoris （SAP）. MethodsA randomised， double-blind， placebo-controlled， multicentre study design was used to enroll 170 patients of SAP from nine centres， which were divided into 85 patients each in the trial group and control group with 1∶1 ratio. Both groups maintained the original western medicine treatment plan， and added Jiuxin Pill or placebo respectively， 2 pills （0.05 g） each time twicely for 28 days. The main outcomes were total exercise time （TED） in the exercise treadmill test and Seattle Angina Questionnaire （SAQ） scores including physical limitation （PL）， angina stability （AS）， angina frequency （AF）， treatment satisfaction （TS）， and disease perception （DP）. The secondary outcomes were exercise treadmill test indicators including heart rate recovery in 1 min （HRR1）， metabolic equivalents （METs）， maximum magnitude of ST-segment depression， and the Borg rating of perceived exertion scale， the average number of angina attacks per week， withdrawal and reduction rate of nitroglycerin， traditional Chinese medicine syndrome scores， incidence of major adverse cardiovascular events. Safety indicators were evaluated and the occurrence of adverse events during the trial was recorded. Data was collected before treatment， day 28±2 in treatment period， and follow-up at day 56 which is 28±2 days after treatment period finished. ResultsEighty-four and eighty-five patients respectively from trial group and control group were included to the full analysis set （FAS） and safety analysis set （SS）. Compared with the group before treatment and with the control group after treatment， the trial group had higher TED， HRR1， and METs， and lower maximum magnitude of ST-segment depression and Borg rating of perceived exertion scores after treatment （P＜0.01）. Compared with the group before treatment and with the control group after treatment and at follow-up， the total SAQ score and scores of AS， AF， TS and DP of the trial group after treatment and at follow-up elevated， while the average number of angina attacks per week and traditional Chinese medicine syndrome scores reduced （P＜0.01）. There was no statistically significant difference in the withdrawal and reduction rate of nitroglycerin between groups （P＞0.05）. Major adverse cardiovascular events occurred in 1 case （1/84， 1.19%） in the trial group and 1 case （1/85， 1.18%） in the control group， and the difference between groups was not statistically significant （P＞0.05）. A total of 3 cases of adverse events occurred in the trial group （3/84， 3.57%）， and a total of 6 cases of adverse events occurred in the control group （6/85， 7.06%）， and there was no statistically significant difference in the incidence of adverse events between groups （P＞0.05）. ConclusionIn the treatment of SAP， Jiuxin Pill combined with conventional western medicine can further enhance exercise tolerance， improve quality of life， and demonstrate great safety.

Objective:To compare the mid-term clinical effects of AngioJet rheolytic thrombectomy assisted catheter-directed thrombolysis (ART+CDT) with catheter-directed thrombolysis (CDT) in the treatment of acute deep venous thrombosis of lower extremities.Methods:Ninety-one patients admitted to the Department from Jan 2016 to Dec 2017 were placed with inferior vena cava filters and divided into ART+CDT group (30 cases)and CDT group (61 cases). Total urokinase dosge, thrombolytic time, operative cost, length of hospital stay, detumescence rate, thrombus clearance rate, cumulative patency rate of lower limb veins, Villalta score at 2 years and 5 years, thrombosis recurrence rate and chronic venous insufficiency quality of life questionnaire were compared between the two groups.Results:The success rate of surgery was 100% in both groups, there was no mortality. There were significant differences in the short-term postoperative outcomes between the two groups in terms of total dosage of urokinase, thrombolysis time, total cost of surgery, length of hospital stay, detumescence rate, venous patency scores before and after treatment, and venous patency rate (all P<0.05). For the mid- and long-term postoperative outcomes of 2 and 5 years, there were no significant differences in the incidence of PTS, recurrence rate of thrombus, chronic venous function scale, and cumulative patency rate at 2 years (all P>0.05). Conclusions:ART+CDT has a significant advantage over CDT alone in terms of early efficacy and early reopening of blood flow in patients. Both ART+CDT and CDT have a low incidence of PTS and a low recurrence rate of thrombus in the mid-term follow-up, and both have satisfactory performance in the mid- and long-term efficacy of interventional treatment of deep venous thrombosis of lower limbs.

Hepatitis C is distributed worldwide and possesses a hidden characteristic. The traditional methods of screening and diagnosis of hepatitis C infection commonly used in clinics are based on anti-HCV antibody and HCV RNA detection. Advances in HCV antigen detection technologies can apparently reduce the window period for anti-HCV antibodies, providing new clinical evidence for the early detection, diagnosis, and treatment of HCV infection. This article is a current review of HCV antigen detection methodologies, clinical applications, and detection strategies.

Eclipta prostrata L.has been used in traditional medicine and known for its liver-protective properties for centuries.Wedelolactone(WEL)and demethylwedelolactone(DWEL)are the major coumarins found in E.prostrata L.However,the comprehensive characterization of these two compounds on non-alcoholic fatty liver disease(NAFLD)still remains to be explored.Utilizing a well-established zebrafish model of thioacetamide(TAA)-induced liver injury,the present study sought to investigate the impacts and mechanisms of WEL and DWEL on NAFLD through integrative spatial metabolomics with liver-specific transcriptomics analysis.Our results showed that WEL and DWEL significantly improved liver function and reduced the accumulation of fat in the liver.The biodistributions and metabolism of these two compounds in whole-body zebrafish were successfully mapped,and the discriminatory endogenous metabolites reversely regulated by WEL and DWEL treatments were also characterized.Based on spatial metabolomics and transcriptomics,we identified that steroid biosynthesis and fatty acid metabolism are mainly involved in the hepatoprotective effects of WEL instead of DWEL.Our study unveils the distinct mechanism of WEL and DWEL in ameliorating NAFLD,and presents a"multi-omics"platform of spatial metabolomics and liver-specific transcriptomics to develop highly effective compounds for further improved therapy.

Ischemic stroke is the second leading cause of death worldwide with limited medications and neuroinflammation was recognized as a critical player in the progression of stroke, but how to control the overactive neuroinflammation is still a long-standing challenge. Here, we designed a novel SIRT6 activator MDL-811 which remarkably inhibited inflammatory response in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages and primary mouse microglia, which were abolished by silencing SIRT6. RNA-seq screening identified the forkhead box C1 (

Objective: To investigate the efficacy and safety of cuboid stereotactic aspiration of necrotic brain tissue for treating malignant middle cerebral artery infarction in the elderly patients. Methods: Sixteen elderly patients with malignant middle cerebral artery infarction were selected from June 2017 to January 2019 in our hospital. Patients were followed up for 6 months to evaluate the efficacy of stereotactic aspiration of necrotic brain tissue using the modified Rankin Scale (mRS). Results: The 30-day mortality was 18.75%. Among the 16 elderly patients, 6 (37.5%) had an mRS score of 3 (defined as moderate disability), 6 (37.5%) had an mRS score of 4 (defined as moderate to severe disability), 1 (6.25%) had an mRS score of 5 (defined as severe disability), and 3 (18.75%) had an mRS score of 6. The probability of 6-month favorable outcome, defined as an mRS score of ≤3, was 37.5%, and the 6-month mortality was 18.75%. Conclusions It is a simple, minimally invasive, effective and safe method to treat malignant middle cerebral artery infarction in the elderly patients with cuboid stereotactic aspiration of necrotic brain tissue, which needs to be confirmed by further randomized controlled studies.

OBJECTIVE： To establish a method for simultaneous determination of gallic acid， cinnamic acid and catechin in 3 processed products of Rheum officinale. METHODS： RP-HPLC method was established. The determination was performed on Thermo ScientificTM Hypersil GOLD Dim column with mobile phase consisted of methanol-0.1％ phosphoric acid solution （gradient elution） at the flow rate of 1.0 mL/min. The detection wavelength was set at 278 nm， and the column temperature was 30 ℃. The sample size was 10 μL. RESULTS： The linear range of gallic acid， cinnamic acid and catechin were 0.126 2-1.262 0 μg（r＝0.999 9）， 0.036 2-0.362 0  μg（r＝0.999 9） and 0.177 9-1.779 4 μg（r＝0.999 8）， respectively. Quantitative limits were 25.4， 28.2， 62.5 ng， and detection limits were 6.2， 3.6， 11.8 ng， respectively. RSDs of precision， stability， repeatability and durability tests were all less than 3％. The recoveries ranged from 94.64％-102.71％（RSD＝2.74％， n＝9）， 95.35％-102.49％（RSD＝2.44％， n＝9）， 93.56％-103.66％（RSD＝3.27％， n＝9）. The determination results showed that the contents of gallic acid and cinnamic acid in prepared R. officinale were higher， and the order of both were prepared R. officinale＞steamed R. officinale＞raw R. officinale. The content of catechin in raw R. officinale was higher， and the order of it was raw R. officinale＞ steamed R. officinale＞prepared R. officinale. CONCLUSIONS： The method is sensitive， reliable and reproducible. It can be used to determine the contents of gallic acid， cinnamic acid and catechins in 3 processed products of R. officinale simultaneously.

Objective To explore the effect of invasion and migration of hepatocellular carcinoma (HCC) endothelial cells (TECs) affected by overexpression of microRNA-3178 (miR-3178) through the transfection of miR-3178 mimic.Methods Real-time polymerase chain reaction (Real-time PCR) was used to identify differential expression of miR-3178 in normal hepatic sinusoidal endothelial cells (HSECs) and HCC TECs.Furthermore,HCC TECs were divided into 3 groups:control (CON) group,miRNA-3178 upregulation (Mimics,up-regulation of miR-3178 expression was achieved using miR-3178 mimics transfected into HCC TECs) group and negative control (NC,negative control sequence was transfected into HCC TECs) group.RT-PCR was used to detect expression of miR-3178 in HCC TECs before and after transfection.Transfection efficiency was observed by using an inverted fluorescence microscope.HCC TECs invasionand migration were measured by matrigel invasion and transwell migration assay.EGR3 protein expression of HCC TECs were identified by Western blotting analysis.EGR3 mRNA expression of HCC TECs were identified by RT-PCR analysis.Results The results of RT-PCR showed that miR-3178 was significantly down-regulated in HCC TECs compared to HSECs (P ＜0.05),and expression of miR-3178 was significantly increased after the transcienttransfection (P ＜ 0.05).The transfection efficiency in HCC TECs was morethan 90％.Number of migrated and invaded cells and in miR-3178 group was significantly less than those in other groups.Target gene prediction software showed EGR3 was a possible candidate target.Transfection of miR-3178 mimic significantly decreased the mRNA and protein expression levels of EGR3.Conclusion MiR-3178 was downregulated in HCC TECs and overexpression of miR-3178 can specifically inhibit migration and invasion of HCC TECsin vitro through inhibiting EGR3 expression,thus,miR-3178 might be a critical targeted therapy strategv for HCC.
