In conclusion, high-fat diet can lead to IL17A upregulation, VICs myofibroblastic transition and inflammatory cells infiltration in the aortic value of ApoE-/- mice. Blocking IL17A with IL17A mAb can alleviate aortic valve inflammatory states.Cancer testis (CT) antigens have received particular attention in cancer immunotherapy. OY-TES-1 is a member of CT antigens. This study was to evaluate OY-TES-1 expression and immunogenicity in hepatocelluar carcinoma (HCC). OY-TES-1 mRNA expression was detected in 56 HCC tissues and 5 normal liver tissues by reverse transcriptase PCR (RT-PCR). Of the 56 cases of HCC tissues tested, 37 cases had tumor and matched adjacent non-cancer tissues and were subjected to both RT-PCR and quantitative real-time PCR. OY-TES-1 protein was subsequently observed on a panel of tissue microarrays. Sera from patients were tested for OY-TES-1 antibody by ELISA. To identify OY-TES-1 capable of inducing cellular immune response, OY-TES-1 protein was used to sensitize dentritic cells and the cytotoxicity effect was measured in vitro. The results showed that OY-TES-1 mRNA was highly expressed in 41 of the 56 (73.21%) HCC tissues, whereas none in 5 normal liver tissues. OY-TES-1 mRNA was frequently expressed not only in HCC tissues (72.97%, 27/37), but also in paired adjacent non-cancer tissues (64.86%, 24/37). But the mean expression level of OY-TES-1 mRNA in HCC tissues was significantly higher than that in adjacent non-cancer tissues (0.76854 vs. 0.09834, P=0.021). Immunohistochemistry showed that OY-TES-1 protein expression was detected in 6 of the 49 cases of HCC tissues, and absent in 9 cases of normal liver and 6 cases of cirrhosis tissues. Seropositivity was detected in 10 of the 45 HCC patients, but not detected in 17 cirrhosis patients and 76 healthy donors. The specific cytotoxic T cells elicited by OY-TES-1 could kill HLA-A2+ HCC cell line which expressed OY-TES-1. click here The target lysis was mainly HLA class I -dependent and could be blocked by antibodies against monomorphic HLA class I but not HLA class II molecule. In summary, OY-TES-1 expression is up-regulated in HCC tissues and can be recognized by humoral and cellular responses, which suggests that OY-TES-1 is an attractive target for tumor immunotherapy in HCC.Several studies have indicated that stroke survivors with multiple lesions or with larger lesion volumes have a higher risk of stroke recurrence. However, the relationship between lesion locations and stroke recurrence is unclear. We conducted a prospective cohort study of first-ever ischemic stroke survivors who were consecutively enrolled from January 2010 to December 2015. Stroke recurrence was assessed every 3 months after post-discharge via telephone interviews by trained interviewers. Lesion locations were obtained from hospital-based MRI or CT scans and classified using two classification systems that were based on cerebral hemisphere or vascular territory and brain anatomical structures. Flexible parametric survival models using the proportional hazards scale (PH model) were used to analyze the time-to-event data. Among 633 survivors, 63.51% (n=402) had anterior circulation ischemia (ACI), and more than half of all ACIs occurred in the subcortex. After a median follow-up of 2.5 years, 117 (18.48%) survivors developed a recurrent stroke. The results of the multivariate PH model showed that survivors with non-brain lesions were at higher risk of recurrence than those with right-side lesions (HR, 2.79; 95%CI, 1.53, 5.08; P=0.001). There was no increase in risk among survivors with left-side lesions (HR, 0.97; 95%CI, 0.53, 1.75; P=0.914) or both-side lesions (HR, 1.24; 95%CI, 0.75, 2.07; P=0.401) compared to those with right-side lesions. Additionally, there were no associations between stroke recurrence and lesion locations that were classified based on vascular territory and brain anatomical structures. It was concluded that first-ever ischemic stroke survivors with non-brain lesion had higher recurrence risk than those with right-side lesion, although no significant associations were found when the lesion locations were classified by vascular territory and brain anatomical structures.Dexmedetomidine (DEX), a potent and highly selective agonist for α2-adrenergic receptors (α2AR), exerts neuroprotective effects by reducing apoptosis through decreased neuronal Ca2+ influx. However, the exact action mechanism of DEX and its effects on oxygen-glucose deprivation-reoxygenation (OGD/R) injury in vitro are unknown. We demonstrate that DEX pretreatment reduced OGD/R injury in PC12 cells, as evidenced by decreased oxidative stress, autophagy, and neuronal apoptosis. Specifically, DEX pretreatment decreased the expression levels of stromal interaction molecule 1 (STIM1) and calcium release-activated calcium channel protein 1 (Orai1), and reduced the concentration of intracellular calcium pools. In addition, variations in cytosolic calcium concentration altered apoptosis rate of PC12 cells after exposure to hypoxic conditions, which were modulated through STIM1/Orai1 signaling. Moreover, DEX pretreatment decreased the expression levels of Beclin-1 and microtubule-associated protein 1A/1B-light chain 3 (LC3), hallmark markers of autophagy, and the formation of autophagosomes. In conclusion, these results suggested that DEX exerts neuroprotective effects against oxidative stress, autophagy, and neuronal apoptosis after OGD/R injury via modulation of Ca2+-STIM1/Orai1 signaling. Our results offer insights into the molecular mechanisms of DEX in protecting against neuronal ischemia-reperfusion injury.It has been identified that malnutrition can influence the immune system and time of engraftment, and it's also associated with increased incidence of complications, prolonged length of hospital stays, and transplant mortality and morbidity in patients undergoing hematopoietic stem cell transplantation (HSCT), so dynamic nutrition care is highly important. The aim of this study was to better understand the differences between clinical nutrition practices and international recommendations as well as possible barriers to the use of nutrition support in HSCT patients. An evidence-based nutrition support pathway was constructed through a systematic literature review to identify evidence and recommendations relating to the relevant issues. Then, a questionnaire consisting of 28 questions that focused on the 4 topics, namely, assessment and screening for malnutrition, nutrition support interventions, nutrition support in gastrointestinal graft-versus-host disease (GVHD) and neutropenic diet was developed by the study authors and used for data collection.
