Restrictive cardiomyopathy (RCM) is a rare cardiomyopathy characterized by diastolic dysfunction, which affects cardiac systolic function. We successfully established induced pluripotent stem cells (hiPSCs) from peripheral blood mononuclear cells of 24-year-old male with restrictive cardiomyopathy (RCM). The patient-derived hiPSCs carried heterozygous mutation of CRYAB gene (c.326A > G, p.D109G), which was consistent with clinical whole exon sequencing results. We confirmed the pluripotency, multipotential differentiation and karyotype of hiPSCs. The hiPSCs will be useful for studying the pathogenesis of RCM caused by CRYAB (c.326A > G) mutation.
The MediSim system extends virtual environment technology to allow medical personnel to interact with and train on simulated casualties. The casualty model employs a three-dimensional animated human body that displays appropriate physical and behavioral responses to injury and/or treatment. Medical corpsmen behaviors were developed to allow the actions of simulated medical personnel to conform to both military practice and medical protocols during patient assessment and stabilization. A trainee may initiate medic actions through a mouse and menu interface; a VR interface has also been created by Stansfield’s research group at Sandia National Labs.
Abstract Objective To analyze the efficacy and safety of Liushen Pill combined with basic treatment on patients with COVID-19. Methods One-hundred-eighty-one patients hospitalized with COVID-19, classified as asymptomatic, mild type, were randomly separated into the experimental (n=91) and control (n=90) groups. The control group was given placebo (Maizao decoction), while the experimental group was given Maizao decoction and Liushen pill, in addition to standard care. The negative conversion rate of nucleic acid (Day 7), hospital discharge rate (Day 8, 10, 14), symptom disappearance rate (Day 3, 5, 7), inflammatory cytokines and adverse events between the two groups were compared. Results The negative viral conversion rate in the experimental group was significantly higher than that in the control group (48.35% vs 31.11%, P＜0.05). Subgroup analysis showed a similar significant trend when the Ct value was ≤ 30 at baseline. After 10 days, the hospital discharge rate was significantly higher in the experimental than the control group (69.23% vs 53.33%, P＜0.05). After 3 days of medication, the headache symptoms significantly disappeared in the experimental group (88.57%) compared to the control group (63.33%) (P＜0.05). After 5 days, symptom disappearance rate of headache in the experimental group (97.14%) was still significantly higher than that in the control group (80.00%) (P＜0.05), as was the symptom disappearance rate of cough (82.65% vs 58.93%, P＜0.01). After treatment, the PCT level was significantly lower in the experimental than the control group (0.09±0.00 ng/L vs 0.14±0.05 ng/L) (P＜0.05). There were no significant between-groups differences in clinical safety test indexes. Conclusion Early intervention with Liushen Pill could improve the symptoms of cough and headache, and increase negative viral conversion and discharge rate.Trial registration Chinese Clinical Trial Registry, No. ChiCTR2200058859.

Abstract Background Sufentanil-induced cough is common during the induction of anesthesia. The objective of this study was to determine whether pretreatment with a small dose of esketamine is effective in treating sufentanil-induced cough. Methods 220 patients were screened, and 200 patients who had scheduled elective surgery and were between 18 and 70 years old were randomly divided into two groups. Before sufentanil was administered, esketamine group (group K) was injected with 0.15 mg/kg esketamine at 5 s, and control group (group C) was administered with the same volume. Within 1 min after sufentanil(0.4ug/kg) injection during induction, cough incidence and severity were evaluated. After sufentanil was injected, we recorded its hemodynamic changes and side effects. Results In the esketamine group (group K) and control group (group C), there was an incidence of cough of 5 and 34%, respectively. The esketamine group (group K) had a significantly lower incidence and severity of cough compared to the control group (group C) immediately after sufentanil injection ( P < 0.05). MAP and HR did not differ significantly between the two groups during three different times of general anesthesia induction ( P > 0.05). Conclusion In our study, we found that sufentanil-induced cough was significantly reduced by pretreatment with 0.15 mg/kg esketamine, but with no significant changes in the hemodynamic status.

Ephrin B2 (EFNB2) is the first identified and most widely used marker for arterial endothelial cells (AECs). We generated a heterozygous EFNB2-2A-mCherry reporter H1 cell line, H1-EFNB2-2A-mCherry+/- (WAe001-A-57), by CRISPR/Cas9-mediated insertion of 2A-mCherry cassette into the EFNB2 gene locus, immediately before the translation stop codon. The H1-EFNB2-2A-mCherry reporter cells were pluripotent and could differentiate into all three germ layer lineages. Simultaneous expression of mCherry was observed when expression of EFNB2 was increased during endothelial cell differentiation. Thus, the generated reporter cells enable live identification of EFNB2-positive AECs, and screening of small molecule compound and target genes that promote AEC differentiation.
Abstract Background Psoriasis is a chronic inflammatory dermatosis with complex genetic basis supported by family investigation. Renal involvement in psoriasis is sparsely studied and its pathogenesis is still unclear. Methods and Results We describe the case of a 7‐year‐old boy presented new onset of nephropathy two weeks after a flare‐up of psoriasis. His mother had a long history of psoriasis without abnormal urinalysis records. The case showed non‐nephrotic range proteinuria, microscopic hematuria without any other abnormal results including renal function, complement cascade, and ultrasound. Renal pathological demonstrated the diagnosis of C3 glomerulonephritis (C3GN) showing mesangial proliferative glomerulonephritis with C3 staining only, effacement of podocyte process and intramembranous electron dense deposit by electric microscopy. Parent‐child trio WES performed to screening the common variants of psoriasis susceptibility locus and also the rare variants associated with C3GN. We identified a missense single nucleotide polymorphism of CARD14 (*607211, rs34367357, p.Val585Ile) carried by the proband and his mother. Meta‐analysis proved the association of rs34367357 and psoriasis ( p = 0.006, OR = 1.23). A hemizygouse mutation of CLCN5 (*300008, c.1904A＞G,p.Asn635Ser) was identified for diagnosis of Dent disease (*300009). Conclusion The case highlights the genetic study is necessary to facilitate disease differentiation in new onset of nephropathy with psoriasis in children.
In the past decades, researchers discovered the contribution of genetic defects to the pathogenesis of primary cardiomyopathy and tried to explain the pathogenesis of these diseases by establishing a variety of disease models. Although human heart tissues and primary cardiomyocytes have advantages in modeling human heart diseases, they are difficult to obtain and culture in vitro . Defects developed in genetically modified animal models are notably different from human diseases at the molecular level. The advent of human induced pluripotent stem cells (hiPSCs) provides an unprecedented opportunity to further investigate the pathogenic mechanisms of inherited cardiomyopathies in vitro using patient-specific hiPSC-derived cardiomyocytes. In this review, we will make a summary of recent advances in in vitro inherited cardiomyopathy modeling using hiPSCs.
