ABSTRACT

OBJECTIVE@#To explore the clinical and genetic characteristics of a patient with hypertrophic cardiomyopathy as the initial manifestation of Mucopolysaccharidosis type Ⅲ A (MPS Ⅲ A).@*METHODS@#A female patient with MPS Ⅲ A who was admitted to the Affiliated Hospital of Jining Medical University in January 2022 and her family members (seven individuals from three generations) were selected as the study subjects. Clinical data of the proband were collected. Peripheral blood samples of the proband was collected and subjected to whole exome sequencing. Candidate variants were verified by Sanger sequencing. Heparan-N-sulfatase activity was determined for the disease associated with the variant site.@*RESULTS@#The proband was a 49-year-old woman, for whom cardiac MRI has revealed significant thickening (up to 20 mm) of left ventricular wall and delayed gadolinium enhancement at the apical myocardium. Genetic testing revealed that she has harbored compound heterozygous variants in exon 17 of the SGSH gene, namely c.545G>A (p.Arg182His) and c.703G>A (p.Asp235Asn). Based on guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be pathogenic (PM2_Supporting +PM3+PP1Strong+PP3+PP4; PS3+PM1+PM2_Supporting +PM3+PP3+PP4). Sanger sequencing confirmed that her mother was heterozygous for the c.545G>A (p.Arg182His) variant, whilst her father, sisters and her son were heterozygous for the c.703G>A (p.Asp235Asn) variant. Determination of blood leukocyte heparan-N-sulfatase activity suggested that the patient had a low level of 1.6 nmol/(g·h), whilst that of her father, elder and younger sisters and son were all in the normal range.@*CONCLUSION@#The compound heterozygous variants of the SGSH gene probably underlay the MPS ⅢA in this patient, for which hypertrophic cardiomyopathy is an associated phenotype.

ABSTRACT

Objective:To investigate the effect of Astragaloside Ⅳ on high glucose-induced cardiomyocyte pyroptosis.Methods:H9c2 cells were cultured in vitro and divided into control group(5.5 mmol/L glucose), high glucose group(33.3 mmol/L glucose), Astragaloside Ⅳ group(33.3 mmol/L glucose+ 100μmol/L Astragaloside Ⅳ), and NLRP3 inhibitor group(33.3 mmol/L glucose+ 1μmol/L MCC950). Cell counting kit 8(CCK-8)was used to detect the activity of H9c2 cells.Lactate dehydrogenase(LDH)kit was used to detect the content of LDH in cell supernatant.Superoxide anion fluorescent probe(DHE)was used to detect the level of intracellular reactive oxygen species(ROS). Real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)and Western blot were used to detect the mRNA and protein expression levels of pyroptosis-related genes.Immunofluorescence was used to detect the fluorescence intensity of NLRP3.Enzyme-linked immunosorbent assay(ELISA)was used to detect the level of inflammatory factors in cell supernatant.Results:When the concentration of Astragaloside Ⅳ was 100 μmol/L, it could significantly inhibit the decrease of cardiomyocyte viability induced by high glucose( P<0.01)and reduce LDH release( P<0.01). Compared with the control group, the level of ROS was increased( P<0.01), the mRNA and protein expressions of pyroptosis-related molecules were up-regulated( P<0.01 for all), the fluorescence intensity of NLRP3 was increased( P<0.01), and the levels of inflammatory factors in the cell supernatant were increased in the high glucose group( P<0.01). Compared with the high glucose group, the ROS level was decreased( P<0.01), the mRNA and protein expressions of pyroptosis-related molecules were down-regulated( P<0.05 or P<0.01), the fluorescence intensity of NLRP3 was decreased( P<0.01), and the levels of inflammatory factors in cell supernatant were decreased( P<0.05 or P<0.01)in Astragaloside Ⅳ group and inhibitor group. Conclusions:Astragaloside Ⅳ plays a protective role in high glucose-induced cardiomyocyte injury by inhibiting NLRP3/Caspase-1 signaling pathway and inhibiting pyroptosis.Moreover, it can improve the anti-inflammatory and antioxidant properties in cell models.

ABSTRACT

Objective:To investigate the protective effects and related mechanisms of Astragaloside Ⅳ(ASⅣ)alleviating Angiotensin II-induced cardiomyocyte hypertrophy.Methods:H9c2 cardiomyocytes were divided into six groups: normal control group, ASⅣ group(ASⅣ 100 μmol/L), AngⅡ group(AngⅡ 1 μmol/L), and three ASⅣ dose experiments(AngⅡ 1 μmol/L + ASⅣ 25 μmol/l group, AngⅡ 1 μmol/L+ ASⅣ 50 μmol/l group, AngⅡ1 μmol/L+ ASⅣ 100 μmol/L group), and simultaneously cultured for 24 hours.Cardiomyocyte viability was assessed by CCK8 assay, and surface area of culturedcardiomyocytes in each group was assessed by immunofluorescence assay.Atrial natriuretic peptide(ANP)mRNA expression was assessed by fluorescence real-time quantitative RT-PCR.And LC3 protein expression, an autophagy related protein, was assessed by Western blotting as well as immunofluorescence.Results:(1)AngⅡ decreased cardiomyocyte H9c2 viability in a dose-dependent manner( P<0.05). ASⅣ could inhibit the decrease of cardiomyocyte H9c2 viability in response to AngⅡ in a dose-dependent manner( P<0.05). (2)H9c2 cardiomyocytes induced by AngⅡ showed a significantly larger cell area and significantly higher ANP mRNA and ANP protein expression compared with controls.Different concentrations of ASⅣ intervention could reverse the increase of cardiomyocyte H9c2 area induced by AngⅡ and also decreased the expression of ANP protein induced by AngⅡ in a dose-dependent manner(all P<0.05). (3)Compared with the control group, the autophagy level and the expression of autophagy marker LC3II/I of H9c2 cardiomyocytes induced by AngⅡ were significantly increased(all P<0.05). ASⅣ could inhibit AngⅡ-activated autophagy, and the difference was statistically significant( P<0.05). ASⅣ inhibited the expression of LC3II/I in H9c2 cardiomyocytes stimulated by AngⅡ, and the difference was statistically significant( P<0.05). Conclusions:ASⅣ inhibits AngⅡ-induced cardiac hypertrophy by inhibiting autophagy of cardiomyocytes.

ABSTRACT

Stress cardiomyopathy (SCM) is a kind of clinical syndrome characterized by transient ventricular enlargement and left ventricular regional systolic dysfunction caused by strong mental stimulation or physical stress, and accompanied by electrocardiogram (ECG) changes. Its clinical symptoms and ECG manifestations are similar to those of acute coronary syndrome in the early stage of onset, which is easy to be misdiagnosed. However, patients in intensive care unit (ICU) are often in critical and severe condition, and they often preceded different degrees by emotional or physical stress. Therefore, patients in ICU are prone to complicated with SCM. Otherwise, the symptoms of SCM patients in ICU are not typical. Early diagnosis and optimal treatment are the key to improve the prognosis of patients in ICU. The etiology, epidemiology, pathophysiological mechanism, diagnosis and management of SCM in ICU are reviewed in this paper.

ABSTRACT

Objective: To study the impact of astragaloside on ventricular remodeling and peroxisome proliferator activated receptor a (PPARa) expression in pressure-overload rats and to preliminarily explore its mechanism. Methods: Pressure-overload rat's model was established by abdominal aorta constriction (AAC) in 8-week old SD rats and the result was conifrmed by echocardiography at 6 weeks later. Pressure-overload rats were divided into 4 groups with different intragastric treatment: Model control (normal saline) group, Benazepril hydrochloride [10mg/(kg.d)] group, Low-dose astragaloside [40mg/(kg·d)] group and High-dose astragaloside [80mg/(kg.d)] group; in addition, Sham operation group, the rats received intragastricnormal normal saline.n=20 in each group and all animals were treated for 8 weeks. Rat's cardiac structure and function indexes were assessed by echocardiography, hemodynamic parameter was examined by left ventricular intubation, myocardium and blood levels of free fatty acid (FFA) were determined, morphological changes of myocardial tissue was observed by HE and Masson staining, mRNA and protein expressions of PPARa were measured by qRT-PCR and Western blot analysis. Results: Compared with Sham operation group, Model control group showed increased left ventricular mass index(LVMI), collagen volume fraction (CVF) and FFA level, allP<0.05, while decreased mRNA and protein expressions of PPARa, bothP<0.05. Compared with Model control group, Low-dose and High-dose astragaloside groups presented reduced LVMI, CVF and FFA level, allP<0.05-0.01, while elevated mRNA and protein expressions of PPARa, bothP<0.01. Conclusion:Astragaloside IV mayinhibit myocardial remodeling in pressure-overload rats, which might be via up-regulating mRNA and protein expressions of PPARa, enhance myocardiumFFA utilization, and therefore improve myocardial energy metabolism.

ABSTRACT

Ventricular myocytes from hearts of the neonatal SD rats were treated with 10-7,10-6,and 10-5 mol/L simvastatin for 72 hours under high glucose condition. Compared with control group,the viability of cadiomyocyte was significantly lower in high glucose group (P<0.01 ).The activity of lactate dehydrogenase,the relative expressions of NADPH oxidase subunits p22phox,p47phox mRNA,and reactive oxygen species level in the high glucose group were higher than those of control group ( all P<0.05).lndexes mentioned above were significantly improved by simvastatin treatment in a dose-dependent manner.These results suggest that simvastatin ameliorates high glucose-induced injury of cardiomyocytes via increasing the expression of NADPH oxidase mRNA.

ABSTRACT

Objective To study the impact of depression disorder in patients after coronary stent implantation on incidence rate of in-stent restenosis (ISR) in the coronary heart disease( CHD ), and its possible pathophysiological mechanisms. Methods According to the Hamilton Depression Scale (HAMD-24) and Self-rating Depression Scale(SDS) score,95 patients with unstable angina received coronary drug-eluting stent implantation combined with depression disorder were serve as the study group; randomly selecte 246 cases without depression due to unstable angina pectoris after coronary stent implantation as the control group in the same period. The incidence rate of ISR in these two group were observed, and serum aldosterone ( ALD), high-sensitivity C-reactive protein (hs-CRP) ,Leptin levels in two groups were compared. Results The incidence rate of ISR in study group were significantly higher than that of the control group (28/95 vs 46/246, P<0. 05). Following with the aggravation of depression disorder,the incidence rate of ISR were elevated( χ2 =8. 148, P=0.017). Serum ALD,hs-CRP and Leptin levels of study group were significantly higher than the control group 7 days later after drug-eluting stent implantation ( ALD:277.4 ± 35.9 vs 258.9 ± 60.9, t= 3. 459, P= 0. 001; hs-CRP: 12.03 ± 3.06 vs 11.10 ±2. 806, t = 2.573, P = 0.008; Leptin:5.27 t 1.07 vs 4.98 ± 0.99, t= 2.323, P= 0.021 ). Pearson correlation analysis showed that its HAMA-24 score was positively correlated with serum ALD ,hs-CRP and Leptin( r=0.291,P=0.026; r=0.350, P=0.014; r=0. 312, P=0.023) ,and SDS score was positively correlated with hs-CRP( r=0. 302, P= 0. 020). Conclusion Serum ALD, hs-CRP and Leptin levels are higher in patients after coronary stent implantation combined with depression in patients, and the incidence rate of ISR is also higher in these patients, and the rates are elevated according to the aggravation of depression disorder.
