Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P＜0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.

Objective To assess the effects of low-dose esketamine on the median effective dose(ED50)of ciprofol for anesthesia induction in painless gastrointestinal endoscopy.Methods Fifty-nine pa-tients underwent elective painless gastrointestinal endoscopy,26 males and 33 females,aged 18-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ,were divided into two groups by random number table method:esketamine combined with ciprofol group(group EC,n = 29)and ciprofol group(group C,n = 30).Group EC received intravenous injection of esketamine 0.3 mg/kg and group C received the same amount of normal saline 2 minutes before administration of ciprofol.The initial anesthesia induction dose of ciprofol was 0.4 mg/kg.If a positive reaction occurs during the examination,the next patient will receive an increase dose of propofol 0.04 mg/kg,otherwise will decrease by propofol 0.04 mg/kg.The positive reaction was defined that the patient's BIS can not be decreased to 60 2 minutes after anesthesia induction,or the cough or body movement reaction occur at level 2 or above when entering the mirror.The dosage of ciprofol,recovery time,discharge time,the occurrence of intraoperative and postoperative adverse reactions were recorded.The ED50,95%effective dose(ED95)and 95%confidence interval(CI)of the two groups were calculated by Probit probability regression analysis.Results Compared with group C,the dosage of ciprofol,the incidence of hypotension and frequency of administration of vasoactive drugs during the exami-nation process in group EC were significantly reduced(P＜0.05).The ED50 of ciprofol for anesthesia in-duction in painless gastrointestinal endoscopy in group EC was 0.21 mg/kg(95%CI 0.12-0.25 mg/kg)and the ED95 was 0.32 mg/kg(95%CI 0.26-0.39 mg/kg).The ED50 of ciprofol for anesthesia induction in painless gastrointestinal endoscopy in group C was 0.37 mg/kg(95%CI 0.32-0.40 mg/kg)and the ED95 was 0.48 mg/kg(95%CI 0.43-0.54 mg/kg).The ED50 and ED95 of ciprofol for anesthesia induction in painless gastrointestinal endoscopy in group EC was significantly lower than that in group C(P＜0.05).There was no significant difference in other frequency of adverse events between the two groups.Conclusion Esketamine 0.3 mg/kg can reduce the ED50 of ciprofol in painless gastrointestinal endoscopy and reduce the dosage of ciprofol during the examination process,which is safe for painless gastrointestinal endoscopy with stable intraoperative circulation.

BACKGROUND: The benefits of healthy lifestyles are well recognized. However, the extent to which improving unhealthy lifestyles reduces cardiovascular disease (CVD) risk needs to be discussed. We evaluated the impact of lifestyle improvement on CVD incidence using data from the China-PAR project (Prediction for Atherosclerotic Cardiovascular Disease Risk in China). METHODS: A total of 12,588 participants free of CVD were followed up for three visits after the baseline examination. Changes in four lifestyle factors (LFs) (smoking, diet, physical activity, and alcohol consumption) were assessed through questionnaires from the baseline to the first follow-up visit. Cox proportional hazard models were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). The risk advancement periods (RAPs: the age difference between exposed and unexposed participants reaching the same incident CVD risk) and population-attributable risk percentage (PAR%) were also calculated. RESULTS: A total of 909 incident CVD cases occurred over a median follow-up of 11.14 years. Compared with maintaining 0-1 healthy LFs, maintaining 3-4 healthy LFs was associated with a 40% risk reduction of incident CVD (HR = 0.60, 95% CI: 0.45-0.79) and delayed CVD risk by 6.31 years (RAP: -6.31 [-9.92, -2.70] years). The PAR% of maintaining 3-4 unhealthy LFs was 22.0% compared to maintaining 0-1 unhealthy LFs. Besides, compared with maintaining two healthy LFs, improving healthy LFs from 2 to 3-4 was associated with a 23% lower risk of CVD (HR = 0.77, 95% CI: 0.60-0.98). CONCLUSIONS Long-term sustenance of healthy lifestyles or improving unhealthy lifestyles can reduce and delay CVD risk.

Background: The association of serum retinol-binding protein (RBP) levels with nonalcoholic fatty liver disease (NAFLD) remains controversial. Furthermore, few studies have investigated their relationship in type 2 diabetes mellitus (T2DM) patients. Therefore, the aim of the present study was to explore the association between serum RBP levels and NAFLD in Chinese inpatients with T2DM. Methods: This cross-sectional, real-world study included 2,263 Chinese T2DM inpatients. NAFLD was diagnosed by abdominal ultrasonography. The subjects were divided into four groups based on RBP quartiles, and clinical characteristics were compared among the four groups. The associations of both RBP levels and quartiles with the presence of NAFLD were also analyzed. Results: After adjustment for sex, age, and diabetes duration, there was a significant increase in the prevalence of NAFLD from the lowest to the highest RBP quartiles (30.4%, 40.0%, 42.4%, and 44.7% for the first, second, third, and fourth quartiles, respectively, P<0.001 for trend). Fully adjusted multiple logistic regression analysis revealed that both increased RBP levels (odds ratio, 1.155; 95% confidence interval, 1.012 to 1.318; P=0.033) and quartiles (P=0.014 for trend) were independently associated with the presence of NAFLD in T2DM patients. Conclusion Increased serum RBP levels were independently associated with the presence of NAFLD in Chinese T2DM inpatients. Serum RBP levels may be used as one of the indicators to assess the risk of NAFLD in T2DM patients.

Objective:To investigate anticoagulant effects of mechanical methods in obese patients undergoing laparoscopic sleeve gastrectomy (LSG).Methods:In this prospective study, 54 obese patients receiving LSG were enrolled . All patients were given post-op mechanical methods for thrombogenic interventions. BMI and the operation-related factors were recorded. Venous blood specimens were taken from each patient before surgery, at the end of pneumoperitoneum (i.e., 0 h after surgery), at 24 hours after surgery for prothrombin time (PT) and activated partial thromboplastin time (APTT), fibrinogen (FIB) and D-dimer (D-D).Results:All 54 obese patients successfully underwent LSG. No severe complications were observed. Before operation, the mean BMI was (43.49±8.29) kg/m 2. DVT-2600 device was applied in all patients for 3 consecutive days after surgery. The PT values increased at 0 h, 24 h after surgery [(12.4±1.2) s, (12.4±0.8) s vs. (11.2±0.8) s, P=0, 0]. The APTT values at 0 h, 24 h after surgery decreased [(29.7±3.6) s, (29.0±3.1) s vs.(31.2±3.3) s, P=0.020, 0.001]. However, the D-D values increased at 0 h,24 h after operation [(213±143) ng/ml ,(445±237) ng/ml vs. (85±108) ng/ml, P=0, 0]. All patients were followed up for 1 month, and no thrombosis -related complications were observed. Conclusion:Mechanical methods for obese patients after LSG can help decrease the risk of deep venous thrombosis.

OBJECTIVE: To identify traditional Chinese drugs that contain active ingredients for treatment of myocardial infarction (MI) and explore their therapeutic mechanisms using network pharmacology and molecular docking technology. METHODS: The TCMSP database was used for screening the traditional Chinese drugs containing active ingredients for treating MI, and the related targets of MI and the candidate drugs were obtained from Genecards, OMIM, PharmGkb and PharmMapper databases. The common target network of the drug targets and disease targets was established using Venny2.1.0 software. GO and KEGG signal pathway enrichment analysis of the common targets was performed, and the protein-protein interaction (PPI) network was constructed for the targets. The targets in the PPI network were analyzed to identify the key targets, for which GO and KEGG pathway enrichment analyses were performed. Molecular docking was performed for the candidate ingredients and the key targets, and a total score ≥6 was used as the criteria for screening the therapeutic ingredients and their docking binding with key targets was verified. A human umbilical vein endothelial cell (HUVEC) model of oxygen-glucose deprivation (OGD) was used to validate the candidate ingredients and the key therapeutic targets for MI by Western blotting. RESULTS: Our analysis identified Salvia miltiorrhiza and Dalbergiae odoriferae as the candidate drugs rich in active ingredients for treatment of MI. These ingredients involved 16 key therapeutic targets for MI, which participated in such biological processes as inflammatory response, angiogenesis, energy metabolism and oxidative stress and the pathways including HIF-1, VEGF, and TNF pathways. Sclareol and PTGS2 in Salvia miltiorrhiza and formononetin and KDR in Dalbergiae odoriferae all had high docking total scores. Western blotting showed that at medium and high doses, sclareol significantly inhibited PTGS2 expression and formononetin promoted KDR expressions in the cell models in a dose-dependent manner (P < 0.05). CONCLUSION Both Salvia miltiorrhiza and Dalbergiae odoriferae have good therapeutic effects on MI. Sclareol in Salvia miltiorrhiza and formononetin in Dalbergiae odoriferae regulate the expressions of KDR and PTGS2, respectively, to modulate the inflammatory response, angiogenesis, oxidative stress and energy metabolism and thus produce myocardial protective effects.
