BECN1 regulates FADD/RIPK1/Caspase-8 complex formation via RIPK1 ubiquitination by downregulating OTUD1 in MI/R induced myocyte apoptosis.

BACKGROUND: Cardiomyocyte apoptosis plays a vital role in myocardial ischemia-reperfusion (MI/R) injury; however, the role of beclin1 (BECN1) remains unclear. This study aimed at revealing the function of BECN1 during cardiomyocyte apoptosis after MI/R injury. METHODS: In vivo, TTC and Evan's blue double staining was applied to verify the gross morphological alteration in both wild type (WT) mice and BECN1 transgene mice (BECN1-TG), and TUNEL staining and western blot were adopted to evaluate the cardiomyocyte apoptosis. In vitro, a hypoxia/reoxygenation (H/R) model was established in H9c2 cells to simulate MI/R injury. Proteomics analysis was preformed to verify if apoptosis occurs in the H/R cellular model. And apoptosis factors, RIPK1, Caspase-1, Caspase-3, and cleaved Caspase-3, were investigated using western bolting. In addition, the mRNA level were verified using RT-PCR. To further investigate the protein interactions small interfering RNA and lentiviral transfection were used. To continue investigate the protein interactions, immunofluorescence and coimmunoprecipitation were applied. RESULTS: Morphologically, BECN1 significantly attenuated the apoptosis from TTC-Evan's staining, TUNEL, and cardiac tissue western blot. After H/R, a RIPK1-induced complex (complex II) containing RIPK1, Caspase-8, and FADD was formed. Thereafter, cleaved Caspase-3 was activated, and myocyte apoptosis occurred. However, BECN1 decreased the expression of RIPK1, Caspase-8, and FADD. Nevertheless, BECN1 overexpression increased RIPK1 ubiquitination before apoptosis by inhibiting OTUD1. CONCLUSIONS: BECN1 regulates FADD/RIPK1/Caspase-8 complex formation via RIPK1 ubiquitination by downregulating OTUD1 in C-Caspase-3-induced myocyte apoptosis after MI/R injury. Therefore, BECN1 can function as a cardioprotective candidate.

Prediction of outcomes in patients with local recurrent nasopharyngeal carcinoma: development and validation of a four-factor prognostic model integrating baseline characteristics and [18F]FDG PET/CT parameters.

OBJECTIVES: To investigate the prognostic value of [18F]FDG PET/CT parameters in local recurrent nasopharyngeal carcinoma (lrNPC) and establish a prognostic tool for lrNPC patients based on these [18F]FDG PET/CT parameters. METHODS: A total of 358 lrNPC patients seen from 2010 to 2019 at Sun Yat-sen University Cancer Center with complete baseline characteristics and [18F]FDG PET/CT data were retrospectively analyzed. Maximal standardized uptake value (SUVmax), SUVmean, SUVpeak, metabolic tumor volume (MTV), total lesion glycolysis (TLG), and heterogeneity index (HI) for recurrent nasopharynx tumors were included. Cox regression analysis was performed to select candidate variables. Subsequently, a nomogram for predicting overall survival (OS) for lrNPC patients was developed and internally validated. RESULTS: Multivariate Cox analysis results suggested that age ≥ 47 years (hazard ratio (HR), 1.62 (1.18-2.24); p = 0.003)，with smoking history (HR, 1.41 (1.01-1.98); p = 0.046), recurrent T stage {[rT3 vs rT1/2: HR, 1.81 (1.04-3.12); p = 0.037]; [rT4 vs rT1/2: HR, 2.46 (1.32-4.60); p = 0.005]}, and TLG {[37.1-184.3 vs ≤ 37.1: HR, 2.26 (1.49-3.42); p < 0.001]; [>184.3 vs ≤ 37.1: HR, 4.31 (2.50-7.43); p < 0.001]) were independent predictors of OS. A 4-factor nomogram was generated to stratify patients into 3 risk groups. This novel model showed good discrimination with a high C-index (0.752, 95%CI: 0.714-0.790). In addition, the calibration curves showed good agreement between the predicted probabilities and actual observations and decision curve analysis (DCA) suggested that the nomogram was useful for clinical decision-making. CONCLUSIONS: Our study confirmed that [18F]FDG PET/CT parameters were valuable in predicting OS and PFS for lrNPC patients. The 4-factor prognostic model combing baseline patient characteristics with [18F]FDG PET/CT parameters for lrNPC patients had good discrimination, agreement, and clinical application potential. KEY POINTS: • [18F]FDG PET/CT parameters were valuable in predicting OS and PFS for lrNPC patients. • The novel 4-factor nomogram for lrNPC patients had good discrimination, agreement, and potential for clinical application.

Objective:To investigate the effects of 30% ethanol elution fraction of Artemisia absinthium extract with macroporous resin (AAEM-30%) on the dendritic cell (DC) and immunity of mice. Methods:AAEM-30% was obtained from the alcoholic extracts of A. absinthium by AB-8 macroporous resin, and its polysaccharide, flavonoid, and terpenoid contents were determined. The expressions of AAEM-30% on DC surface molecular cluster of differentiation (CD) 40, CD80 and CD86 were detected in vitro by flow cytometry, and the expressions of DC cytokines IL-6 and tumor necrosis factor-α (TNF-α) were detected by enzyme linked immunosorbent assay (ELISA). The effect of AAEM-30% on the immune function of ICR mice was measured in vivo with different doses (50 and 100 mg/kg) and different administration methods (subcutaneous injection, intraperitoneal injection, and gavage). Results:The contents of polysaccharides, flavonoids, and terpenoids in AAEM-30% were 24.30%, 22.50% and 28.19%, respectively. AAEM-30% significantly enhanced the expression of CD40, and CD86 and the secretion of IL-6 and TNF-α (all P<0.001). Compared with the control group, no statistically significant differences were found in the body mass of mice compared with the three administration methods (all P>0.05). The thymus index in the 50 and 100 mg/kg AAEM-30% intraperitoneal injection groups and the spleen index in the 50 mg/kg AAEM-30% gavage group were increased (all P<0.05). CD19 + cells increased in the 100 mg/kg AAEM-30% intraperitoneal injection group ( P<0.01) and in the 50 mg/kg AAEM-30% gavage group ( P<0.05). The CD11b + and CD11c + counts increased in the 100 mg/kg AAEM-30% gavage group ( P<0.05). The number of CD4 + and CD8 + T lymphocytes was increased by both gavage and intraperitoneal administration (all P<0.05). Conclusions:AAEM-30% can promote the maturation of DC and enhanced the immunity of mice without obvious side effects.

Effect of Artemisia absinthium L. extract on the maturation and function of dendritic cells / 国际生物医学工程杂志

Objective:To investigate the effect of silica gel column separation component of Artemisia asiatica (AEM-SC) on the maturation and immune function of mouse dendritic cells (DCs). Methods:Artemisia asiatica components were prepared by macroporous resin eluted with 70% ethanol, and then isolated by silica gel column to obtain AEM-SC. The contents of polysaccharides, flavonoids and triterpenes were quantified. Flow cytometry was used to detect the expression level of DCs surface molecules and antigen phagocytosis ability and to stimulate the proliferation of allogeneic T cells. ELISA method was used to detect the effect of DCs on cytokine secretion. Results:The contents of polysaccharides, flavonoids and triterpenes in AEM-SC were 10.12%, 5.7% and 3.62%, respectively. Functional tests showed that AEM-SC significantly reduced the expression levels of LPS-induced DCs surface molecules CD40, CD86 and MHC-II, reduced the expression levels of inflammatory cytokines IL-12p40, TNF-α and IL-6 (all P<0.05), improve the ability of phygocytosis ( P<0.01), and reduce the ability of DCs to stimulate the proliferation of CD4 +T and CD8 +T lymphocytes in the spleen of mice (all P<0.001). In the inflammatory mouse model experiment, AEM-SC significantly reduced the expression levels of DCs surface molecules CD40, CD86, CD80 (all P<0.001), and the expression levels of inflammatory cytokines TNF-α, IL-12p40 in serum (all P<0.01). Conclusions:AEM-SC can inhibit the maturation of DCs-induced LPS both in vitro and in vivo, indicating that AEM-SC has the immunosuppressive effect.

First-trimester ultrasound screening for prenatal diagnosis of fetal congenital heart disease / 中华围产医学杂志

Objective To investigate the value of standardized ultrasound screening in diagnosis of fetal congenital heart disease (CHD) during the first trimester. Methods This study retrospectively analyzed the clinical data of 8 383 fetuses who received ultrasound screening during the first trimester in the Dongguan Maternal and Child Health Hospital from September 2015 to December 2016. Standardized ultrasound was performed to observe fetal heart position, apical direction, apical four-chamber view, three vessels and trachea view and the thickness of nuchal translucency (NT). Fetuses with thickened NT or fetal CHD observed during the first and second trimester were followed up. Pregnancy outcomes and the growth of newborns within one year after birth were recorded and analyzed. Pathological results after the termination of pregnancy were compared with the results of routine karyotyping and chromosome microarray analysis (CMA). Results (1) A total of 27 cases of fetal CHD were identified during the first trimester giving a detection rate of 0.32% (27/8 383). These included ten (37.0%) of single atrium and/or single ventricle, seven (25.9%) of endocardial cushion defect (including two complicated by persistent arterial trunk), three (11.1%) of hypoplastic right heart syndrome, three (11.1%) of interventricular septal defect, two (7.4%) of hypoplastic left heart syndrome, one (3.7%) of mirror-image dextrocardia and one (3.7%) of right atrial enlargement and severe tricuspid regurgitation. Nineteen out of the 27 cases had NT thickening (NT≥3.0 mm) and 17 of them had a cystic hygroma (NT≥6.0 mm). Among the 27 cases, 22 were terminated in the first trimester which autopsy results were consistent with ultrasound and the other five were rescreened during the second trimester. Thirteen out of the 27 cases received chorionic villus sampling, and seven of them were found to have chromosomal abnormalities by karyotyping and CMA, among whom one was microdeletion of 22q11. (2) Twenty-one cases of CHD were detected in the second-trimester ultrasound screening, including five initially identified in the first trimester. These cases included four (19.0%) of complex cardiac malformations (with three or more malformations), four (19.0%) of interventricular septal defect, three (14.3%) of dextroaortic arch, left subclavian artery vagus and 'U' shaped vascular ring, three (14.3%) of hypoplastic right heart syndrome (including one complicated by coronary artery-right ventricular fistula and one by interventricular septal defect), two (9.5%) of transposition of the great arteries, two (9.5%) of tetralogy of Fallot, one (4.8%) of hypoplastic left heart syndrome, one (4.8%) of Taussig-Bing anomaly and one (4.8%) of coarctation of the aorta. Among the 16 cases first identified in the second trimester, eight had NT thickening, including one with cystic hygroma. Among the 21 cases, two were lost to follow-up after being transferred to another hospital; four with negative results in karyotype analysis and CMA were delivered vaginally at term (37-40 gestational weeks) with 1-min Apgar scores of ten points and postpartum ultrasound of the baby was consistent with the second-trimester ultrasound screening; 15 were terminated and the autopsy confirmed those findings in the second-trimester ultrasound screening. Eleven out of the 21 cases received amniocentesis and five of them were found to be abnormal according to karyotype analysis and CMA, including one of microdeletion of 22q11. Conclusions Standardized first-trimester ultrasound screening is important and of great clinical value in the diagnosis of fetal CHD. Increased NT thickness could be a key indicator of fetal CHD and chromosomal abnormalities in early pregnancy. CMA may facilitate detecting the abnormality of genetic material in fetuses with normal chromosome karyotype.

Glycyrrhiza uralensis Fisch L. crude polysaccharides enhance mouse immunity and immune responses induced by HPV-DNA vaccine / 中华微生物学和免疫学杂志

Objective To investigate the effects of Glycyrrhiza uralensis Fisch L. crude polysac-charides (GUCP) as an adjuvant on the immunity of mice and the immune responses induced by human pap-illoma virus ( HPV)-DNA vaccine. Methods ICR mice were injected with different concentrations of GUCP by different ways to detect the influences of GUCP on body weight, organ indexes and the numbers of immune cells in spleen. C57BL/ 6 mice were co-immunized with HPV-DNA vaccine and GUCP to detect the adjuvant efficacy on antigen-specific cellular and humoral immune responses. Results GUCP in all injected groups had no side effect on mouse body weight and liver, heart, lung and kidney indexes, but intraperitone-al injection of GUCP significantly increased spleen and thymus indexes and the numbers of B cells, CD4+ T cells, macrophages and dendritic cells in spleen. Subcutaneous injection of GUCP significantly increased the numbers of B cells and macrophages in spleen and intragastric administration significantly increased the num-bers of CD4+ and CD8+ T cells in spleen. Furthermore, GUCP as an adjuvant enhanced the antigen-specific CD4+ and CD8+ T cell responses and the levels of IgG, IgG1 and IgG2a induced by HPV-DNA vaccine at a certain degree. Conclusion GUCP enhanced the immunity of mice and the antigen-specific cellular and hu-moral immune responses induced by HPV-DNA vaccine. These results suggested that GUCP might be used as an adjuvant for DNA vaccine.

Adverse reactions of Nedaplatin and Cisplatin in concurrent chemoradiotherapy for locally advanced nasopharyngeal carcinoma / 现代临床护理

Objectives To analyze comparatively the adverse reactions of Nedaplatin(NDP)and Cisplatin(DDP)in concurrent chemoradiotherapy for locally advanced nasopharyngeal carcinoma and summarize the nursing points as well.Methods From March 2012 to March 2013,112 patients with locally advanced nasopharyngeal carcinoma were randomly divided into NDP group and DDP group.Besides intensity modulated radiotherapy for both groups,NDP group were treated with intravenous drop infusion of NDP by 100 mg/m2 and the control group with intravenous drop infusion of DDP by 100 mg/m2 both for three courses of once every three weeks (e.g.day one,day 22 and day 43 during the course).The two groups were compared in terms of therapeutic effects and incidences of adverse reactions.Results The complete remission rates of the NDP group and DDP group were 87.5%and 85.7%,respectively (P>0.05).The incidences of adverse reactions like gastrointestinal reactions and radioactive mucositis in the NDP group were significantly lower than those in the DDP group(P0.05). Conclusions Chemotherapy with NDP combined with radiotherapy for locally advanced nasopharyngeal carcinoma has fewer adverse effects and is easy to be accepted by patients so that their quality of life can be improved.In the application of the two kinds of chemotherapy,we should pay attention to the adverse reactions on patients in order to give pertinent care.
