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.

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.

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 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 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 summarize and analyze the clinical effect of allogeneic hematopoietic stem cell transplantation(alloHSCT) for treating acute myeloid leukemia(AML) in this center.Methods The clinical data of 87 patients with AML receiving allo-HSCT in this hospital from January 2008 to June 2015 were retrospectively analyzed on the overall survival rate(OS) after transplantation,leukemia-free survival rate (LFS) and relapse rate (RR),transplant-related mortality (TRM),moreover the efficacies of HLA-matched (kinship and unrelated) and haploidentical transplantation were compared.Meanwhile the influence of different transplantation of pre-leukemia remission status on transplantation curative effect was analyzed.Results Among 87 cases,OS after 2 years was (73.6±4.7)％ and 2-year LFS was (62.1±5.8)％.During the follow-up period,27 cases (31.3％) relapsed and 23 cases (26.4％) died.The 2-year OS in HLA-matched (kinship and unrelated) and haploidentical transplantation were (76.3± 5.3)％ and (68.5±7.2)％ respectively(P＜0.05) and the 2-year LFS were (60.2±4.8)％ and (56.3±5.7)％ respectively (P＜ 0.05).The incidence rate of aGVHD and infection in haploidentical transplantation group was significantly higher than that in the HLA matched group (kinship and unrelated),but their RR were 26.9 ％ and 29.2 ％ respectively (P＞0.05).The transplantation effect analysis in different leukemia remission state showed that RR in the unreaching CR before transplantation group,reaching CR but minimal residual(MRD) positive group and negative group were 68.7 ％,34.7 ％ and 16.6 ％ respectively.The 2-year LFS were (18.7±5.2)％,(56.5± 6.3)％ and (79.2％ ±5.7)％ respectively (P＜0.05).The 2-year OS were (31.2± 5.3)％,(69.6± 7.2) ％ and (89.6±5.3)％ respectively (P＜0.05).Conclusion allo-HSCT is an effective method for treating AML.Recurrence is the main cause of failure after transplantation therapy.

Objective To explore the clinical value of sagittal CT scan in the diagnosis of congenital esophageal atresia and tracheoesophageal fistula(CEA-TEF).Methods Sagittal CT scanning was performed in 1 7 neonates with clinically suspected CEA-TEF preoperatively. Post-processing methods included multiple planar reconstruction(MPR)and volume rendering(VR).The CT manifestations were compared with the surgical findings.Paired-samples t test and Kappa identity analysis were used to analyze the consistency between two esophageal pouches and position of fistula.Results Among 1 7 cases,sagittal CT images clearly showed the distance between two esophageal pouches and position of fistula.Based on Gross classification,2 cases were included in type ⅢA(11.8%),and 15 cases in type ⅢB(88.2%).The results were satisfactory with the surgical findings with 100% accuracy.The distance between two esophageal pouches determined by VR and MPR had no remarkable differences(t=0.991,P>0.05).The position of fistula determined by VR and MPR had high consistency with the surgical findings (Kappa≥0.75).Conclusion Sagittal CT scanning can significantly limit scanning range and reduce the radiation dose as well as improve image quality,and accurately display and assess the distance between two esophageal pouches and position of fistula in CEA-TEF.It has important application value in diagnosing CEA-TEF in neonates.
