Checkpoint Inhibitor Pneumonitis (CIP) is one of the irAEs that could cause mortality, thereby needs special attention from the clinical physicians. In the present manuscript, the CIP occurred in a unilateral lung in one patient case with advanced oesophageal cancer treated with anti-PD-1 was analysed. Furthermore, a literature review was conducted to investigate its pathogenesis, clinical features, associated risk factors, prevention and the correlation with ICI efficacy, providing valuable information for clinical physicians.","PeriodicalId":91561,"journal":{"name":"Journal of stem cell research and transplantation","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90654881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our previous study found that Calcium-Sensing Receptor (CaSR) is involved in pulmonary vascular remodeling in hypoxic pulmonary hypertension (HPH). However, the relationship of Pulmonary Artery Smooth Muscle Cell (PASMC) phenotypic switching, proliferation, and autophagy in CaSR-related HPH remain unclear. The purpose of this study was to detect the role of a CaSR antagonist, NPS2143, on the vascular remodeling by autophagy modulation under hypoxia. Methods: Hypoxic rat PAH model were simulated in vivo. Meanwhile, mean Pulmonary Artery Pressure (mPAP) was measured while RVI, WT%, and WA% indices were calculated. Immunohistochemistry and Western blot were used to detect phenotypic switching and cell proliferation in pulmonary arteriole. Cell viability was determined in vitro by CCK8 and cell cycle. Cell proliferation, phenotypic switching, autophagy level and PI3K/Akt/mTOR pathways were investigated in human PASMCs through mRNA or Western blot methods. Results: Rats with hypoxic-induced PAH had an increased mPAP, RVI, WT% and WA%. Moreover, expression of CaSR was significantly increased, followed by activation of autophagy (increased LC3b and decreased p62), phenotypic switching of PASMCs (reduced calponin, SMA-a and increased OPN) and pulmonary vascular remodeling. However, NPS2143 weakened these hypoxic effects. The results using hypoxic-induced human PASMCs confirmed that NPS2143 suppressed autophagy and reversed phenotypic switching in vitro by inhibiting PI3K/Akt/mTOR pathways. Conclusions: Our study demonstrates that NPS2143 was conducive to inhibit the proliferation and reverse phenotypic switching of PASMCs by regulating autophagy levels in HPH and vascular remodeling.","PeriodicalId":91561,"journal":{"name":"Journal of stem cell research and transplantation","volume":"324 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78007908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a 68-year-old Chinese woman who presented a painless swelling in right mandibular. Physical examination revealed a painless, soft, poor mobility, doughlike mass swelling which was reached to the floor of the mouth, and MRI showed a circumscribed mass of about 20.0×10.0×12.0 cm size. After complete excision of the cyst through an extraoral approach, histology diagnosed dermoid cyst. Dermoid cyst is uncommon found in the floor of the mouth, where there is a soft, painless, associated dyspnea, dysphagia and dysarthria. Imaging may assist diagnosis. Definitive diagnosis is founded on the histology specimen. According to the location and size of the cyst on each occasion, enucleation via intraoral or extraoral approach will be chosen treatment for cyst in the floor of the mouth. Although malignant degeneration of dermoid cyst of the floor of mouth is extremely rare, there are also such a situation reports. Thus, it is important to remove a cyst before the opportunity for malignancy.","PeriodicalId":91561,"journal":{"name":"Journal of stem cell research and transplantation","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80634834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individual treatments using human autologous cord blood Mononuclear Cells (hucbMNC) containing stem cells have yielded promising results. However, stroke is an entity with heterogenic etiologies including arterial ischemic stroke, hemorrhagic stroke, hemorrhagic infarction, and sinus venous thrombosis in newborns, infants, children, and adults. Hence, any attempt to examine care, non-cellular or cell-based therapies has to merit the specific characteristics of this heterogeneity as far as age, symptoms, diagnostics, pathophysiology, histopathology, clinical course and prevalence are concerned. This review describes the various etiologies of stroke for the Neonatal/Perinatal and childhood subsets of the pediatric population as a basis for established non-cellular and novel cell-based therapeutic approaches using cord blood mononuclear cells in the preclinical and clinical setting. In addition, due to its fundamental importance for cell-based therapeutic strategies for stroke, an account of brain plasticity along with blood-brain barrier function and the distinctions between the developing brain and the adult brain is provided. It is concluded that on the present balance of evidence the pathophysiological characteristics associated with plasticity of the developing brain are closely linked to the pharmacological action of hucbMNC in such a way that cell-based treatment might be more efficacious in pediatric stroke than in adult stroke.","PeriodicalId":91561,"journal":{"name":"Journal of stem cell research and transplantation","volume":"229 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78902005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
