Abstract
OBJECTIVE To investigate the efficacy and safety of intravascular ultrasound (IVUS)-guided rotational atherectomy (RA) combined with cutting balloon for pretreatment of severe calcified lesions in the coronary artery before stent placement. METHODS A total of 120 patients with severe coronary artery calcifications detected by IVUS that required percutaneous coronary intervention (PCI) were recruited from our hospital between January, 2016 to January, 2019. The patients were randomized into two groups for pretreatment of the lesions with semicompliant balloon (SB group, 60 cases) or RA combined with CB (RA+CB group, 60 cases), and drug-eluting stents were implanted after the procedure. The immediate success rate of PCI, vascular parameters detected by IVUS after PCI, and the rates of residual stenosis < 10% were compared between the two groups. The incidences of intraoperative complications and major adverse cardiac events (MACE) within 24 months after the surgery were also observed in the two groups. RESULTS The immediate success rate was significantly higher in RA+CB group than in SB group (P=0.032). After pretreatment and stent placement, the minimum stent lumen diameter (P=0.035), minimum stent lumen cross-sectional area (P=0.029), immediate lumen acquisition, immediate lumen cross-sectional area acquisition and the rate of residual stenosis < 10% were all significantly higher in RA+CB group than in SB group (P < 0.001). The patients in RA+ CB group showed obviously less residual stenosis of lumen cross-sectional area than those in SB group after the surgery (χ2= 7.859, P=0.005). The incidences of intraoperative complications (χ2=5.997, P=0.014) and MACE within 24 months after the operation (χ2=4.285, P=0.038) were significantly lower in RA+CB group than in SB group. CONCLUSION For patients with severe coronary artery calcifications eligible for PCI, RA combined with CB angioplasty can significantly improve the success rate of immediate PCI, expand the lumen diameter and cross-sectional area of the stent after PCI, enhance immediate lumen gain, and reduce the incidence of intraoperative complications and MACE after the operation.

Curcumin improves experimentally induced colitis in mice by regulating follicular helper T cells and follicular regulatory T cells by inhibiting interleukin-21. JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY 2021; 72. [PMID: 34272350 DOI: 10.26402/jpp.2021.1.14] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Accepted: 02/26/2021] [Indexed: 11/03/2022]
Abstract
To determine whether curcumin (Cur) can treat mice with experimentally-induced colitis by regulating follicular helper T cells (Tfh) and follicular regulatory T cells (Tfr) by inhibiting interleukin (IL)-21. In this study, 40 male C57BL/6 mice were randomly grouped into four groups, i.e., normal, trinitrobenzene sulfonic acid (TNBS), TNBS + curcumin, and TNBS + anti-IL-21. Mice with experimental colitis were induced by 100 mg/kg TNBS. The mice in the TNBS + Cur group were treated with 100 mg/kg curcumin for seven days, and mice in the TNBS + anti-IL-21 group were treated with anti-IL-21 (150 μg/mouse) once per week, intraperitoneally, starting on the second day after establishing the experimental colitis model. On day eight, the therapeutic effect of curcumin was evaluated by colon mucosa damage index (CMDI), histological examination, and disease activity index (DAI). Furthermore, the number of CD4 + CXCR5 + PD-1 + Tfh and CD4 + CXCR5 + FoxP3 + Tfr cells were measured by flow cytometry. The mRNA and protein expression of IL-21, Bcl-6, FOXP3, ICOS, and PD-1 in colonic mucosa was detected by reverse transcription polymerase chain reaction and the Western blot technique. Compared with the TNBS group, the DAI, CMDI, histological score, the number of CD4 + CXCR5 + PD-1 + Tfh cells, the expression of IL-21, Bcl-6, ICOS, and PD-1 were significantly decreased in the TNBS + curcumin group and TNBS + anti-IL-21 group; body weight, number of CD4 + CXCR5 + FoxP3 + Tfr cells, and the expression of FoxP3 were observably elevated in the TNBS + curcumin group (all P < 0.05). Curcumin may have a potential therapeutic effect on mice with colitis treated experimentally through regulation of the balance of Tfh and Tfr cells via inhibiting the synthesis of IL-21.

Abstract
BACKGROUND Myasthenia gravis (MG) can occur as a paraneoplastic phenomenon associated with thymoma. The association of MG with renal cell carcinoma (RCC) is not clear. Herein, we describe six cases of MG associated with RCC. METHODS There were 283 patients diagnosed with MG admitted to our hospital from 2014 to 2019. Among them, 6 patients also had RCC. None of them had immune checkpoint inhibitor therapies. We performed a retrospective clinical data collection and follow-up studies of these 6 patients. RESULTS These 6 patients with an average MG onset age of 61.3 ± 13.3 years, were all positive for anti-acetylcholine receptor antibodies. MG symptoms appeared after RCC resection in 3 cases. RCC was discovered after the onset of MG in 2 cases, and synchronously with MG in 1 case. After nephrectomy, the MG symptoms showed a stable complete remission in 1 case. Among them, four patients met the diagnostic criteria of possible paraneoplastic neurological syndromes. CONCLUSIONS Except for thymoma, patients with MG should pay attention to other tumors including RCC. MG may be a paraneoplastic syndrome of RCC, and further studies are needed to elucidate the relationship.

Abstract
OBJECTIVE To investigate the value of quantitative detection of ITGA4 and SFRP2 gene methylation in stool DNA for the early diagnosis and prognostic evaluation of colorectal tumors. OBJECTIVE Real-time PCR was used for quantitative assessment of ITGA4 and SFRP2 gene methylation levels in stool samples of 85 patients with colorectal cancer, 65 patients with colorectal adenoma and 40 healthy subjects. OBJECTIVE The 3 groups were comparable for age and gender composition. Methylated ITGA4 and SFRP2 promoters were detected in 48.2% and 62.4% of patients with colorectal cancer, respectively, with a combined positivity of 81.2%. ITGA4 and SFRP2 promoter methylation was detected in 23.1% and 43.1% of patients with colorectal adenoma, respectively, with a combined positivity of 69.2%. The positivity rates of ITGA4 and SFRP2 methylation were significantly higher in patients with colorectal cancer than in those with colorectal adenoma (P < 0.001; P= 0.001) and healthy subjects (P < 0.001; P < 0.001). In colorectal cancer group, ITGA4 and SFRP2 promoter methylation levels were correlated with postoperative tumor recurrence in colorectal cancer group, and the relapse-free survival rate was significantly lower in positive patients for ITGA4 and SFRP2 promoter methylation than in the negative patients (P=0.0002; P=0.007). Multivariate analysis with the COX proportional hazard regression model showed that methylation of ITGA4 and SFRP2 gene promoters (P=0.01) and the degree of tumor differentiation (P=0.03) were associated with the recurrence of colorectal cancer, and were independent risk factors for the recurrence of colorectal cancer. OBJECTIVE Combined detection of ITGA4 and SFRP2 gene methylation levels in stool DNA can improve the early diagnosis rate of colorectal tumor. ITGA4 and SFRP2 promoter methylation and the degree of tumor differentiation are independent risk factors for colorectal cancer recurrence.

Abstract
Aims Atherosclerotic plaque hypoxia is detrimental for macrophage function. Prolyl hydroxylases (PHDs) initiate cellular hypoxic responses, possibly influencing macrophage function in plaque hypoxia. Thus, we aimed to elucidate the role of myeloid PHDs in atherosclerosis. Methods and results Myeloid-specific PHD knockout (PHDko) mice were obtained via bone marrow transplantation (PHD1ko, PHD3ko) or conditional knockdown through lysozyme M-driven Cre recombinase (PHD2cko). Mice were fed high cholesterol diet for 6–12 weeks to induce atherosclerosis. Aortic root plaque size was significantly augmented 2.6-fold in PHD2cko, and 1.4-fold in PHD3ko compared to controls but was unchanged in PHD1ko mice. Macrophage apoptosis was promoted in PHD2cko and PHD3ko mice in vitro and in vivo, via the hypoxia-inducible factor (HIF) 1α/BNIP3 axis. Bulk and single-cell RNA data of PHD2cko bone marrow-derived macrophages (BMDMs) and plaque macrophages, respectively, showed enhanced HIF1α/BNIP3 signalling, which was validated in vitro by siRNA silencing. Human plaque BNIP3 mRNA was positively associated with plaque necrotic core size, suggesting similar pro-apoptotic effects in human. Furthermore, PHD2cko plaques displayed enhanced fibrosis, while macrophage collagen breakdown by matrix metalloproteinases, collagen production, and proliferation were unaltered. Instead, PHD2cko BMDMs enhanced fibroblast collagen secretion in a paracrine manner. In silico analysis of macrophage-fibroblast communication predicted SPP1 (osteopontin) signalling as regulator, which was corroborated by enhanced plaque SPP1 protein in vivo. Increased SPP1 mRNA expression upon PHD2cko was preferentially observed in foamy plaque macrophages expressing ‘triggering receptor expressed on myeloid cells-2’ (TREM2hi) evidenced by single-cell RNA, but not in neutrophils. This confirmed enhanced fibrotic signalling by PHD2cko macrophages to fibroblasts, in vitro as well as in vivo. Conclusion Myeloid PHD2cko and PHD3ko enhanced atherosclerotic plaque growth and macrophage apoptosis, while PHD2cko macrophages further activated collagen secretion by fibroblasts in vitro, likely via paracrine SPP1 signalling through TREM2hi macrophages.

Abstract
There are many causes of bilateral thalamic lesions, but few cases of dural arteriovenous fistula (DAVF) associated with such lesions have been reported previously. Here, we describe an adult man with reversible rapid progressive dementia (RPD) in whom bilateral thalamic lesions were caused by a DAVF that had six supply arteries and drained into both the venous sinus and cortical veins. A 53-year-old man presented with memory decline and abnormal behavior. Head computed tomography (CT) revealed insignificant low density in the bilateral thalami and high density in the right occipital lobe. Brain magnetic resonance imaging showed hyperintensities in the thalami on T2-weighted images. Magnetic resonance venogram revealed no sign of the straight sinus, but multiple tortuous vessels in the cistern of the vein of Galen. Digital subtraction angiography revealed DAVFs near the tentorium cerebelli draining into the vein of Galen, which caused the vasogenic oedema of the thalami. The patient was then treated by transarterial embolization of the feeders. He gradually recovered after the surgery. RPD with bithalamic lesions caused by DAVF is rare but reversible. Therefore, the early recognition and intervention of DAVFs is crucial for the good prognosis of patients so that fistulas can be embolized in time.

Abstract
OBJECTIVE Osteosarcoma (OS) is a frequent bone malignancy. Long non-coding RNA myocardial infarction associated transcript (MIAT) has been reported to be involved in the development of human cancers, including OS. However, the mechanism underlying MIAT in OS progression remains largely unclear. PATIENTS AND METHODS The expression levels of MIAT and sineoculis homeobox homolog 1 (SIX1) in OS tissues and cells were detected by quantitative real-time polymerase chain reaction and Western blot. Cell viability, apoptosis, migration and invasion of OS cells were determined by MTT, flow cytometry and trans-well assays, respectively. The target interaction among MIAT, miR-141-3p and SIX1 was analyzed by bioinformatics analysis and luciferase reporter assay. Phosphatidylinositide 3-kinases (PI3K)/protein kinase B (AKT) pathway was evaluated by Western blot. RESULTS MIAT and SIX1 expression levels were enhanced in OS tissues and cells. Knockdown of MIAT or SIX1 repressed cell viability, migration and invasion but promoted apoptosis in OS cells. Moreover, overexpression of SIX1 reversed the inhibitive role of MIAT silence in OS progression. Furthermore, MIAT could increase SIX1 expression by competitively sponging miR-141-3p. Besides, inhibition of MIAT blocked PI3K/AKT pathway by decreasing SIX1 in OS cells. CONCLUSIONS MIAT silence suppresses OS progression through inactivating PI3K/AKT signaling by sponging miR-141-3p to regulate SIX1, indicating a novel target for the treatment of OS.

Abstract
Stroke is the leading cause of adult disability and death worldwide. Mitochondrial dysfunction has been recognized as a marker of neuronal death during ischemic stroke. Maintaining the function of mitochondria is important for improving the survival of neurons and maintaining neuronal function. Damaged mitochondria induce neuronal cell apoptosis by releasing reactive oxygen species (ROS) and pro-apoptotic factors. Mitochondrial fission and fusion processes and mitophagy are of great importance to mitochondrial quality control. This paper reviews the dynamic changes in mitochondria, the roles of mitochondria in different cell types, and related signaling pathways in ischemic stroke. This review describes in detail the role of mitochondria in the process of neuronal injury and protection in cerebral ischemia, and integrates neuroprotective drugs targeting mitochondria in recent years, which may provide a theoretical basis for the progress of treatment of ischemic stroke. The potential of mitochondrial-targeted therapy is also emphasized, which provides valuable insights for clinical research.

Abstract
OBJECTIVES Alzheimer's disease (AD) is a well-known neurodegenerative disease, of which the hallmark is the disposition of β-amyloid (Aβ) in the form of plaque in the brain. Neprilysin (NEP) is the major enzyme to degrade Aβ and prevent accumulation of Aβ. The present study was undertaken to elucidate the correlation between the NEP gene polymorphisms and AD in Chinese Tibetan population. METHODS Ninety-nine sporadic AD Tibetan patients and 113 healthy Tibetan controls were enrolled in this study. The genotype frequencies and allele frequencies of multiple NEP gene loci were analyzed using the case-control association analysis. RESULTS No significant correlation was found between polymorphisms of NEP gene loci (rs9829757, rs1816558, rs6776185, rs3736187, rs701109, rs989692) and the occurrence of AD in Tibetan population. However, allele C of NEP gene locus (rs701109) and allele T of gene locus (rs3736187) were possible risk factors of male AD patients in Tibetan population. CONCLUSIONS NEP gene loci (rs701109, rs989692, rs9829757, rs3736187, rs1816558, rs6776185) were polymorphic in Tibetan population. No difference was found between these loci but for that male gender combined with allele C of NEP gene locus (rs701109) and T of gene locus (rs3736187) might be risk factors for AD in Tibet.

Abstract
BACKGROUND Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) syndrome is an immune-mediated, treatable and inflammatory central nervous system (CNS) disease with unknown pathogenesis and polymorphic clinical and radiological manifestations. However, juxtacortical lesions have scarcely reported in patients with CLIPPERS. CASE PRESENTATION In this study, we report 32 year old man with complaint of intermittent dizziness, disordered fluency and walking difficulties for 2 weeks. The neuroimaging revealed multiple punctuate hyperintensities on T2-weighted images, with pepper-like gadolinium enhancement in the typical lesions of brainstem, cerebellum, periventricular as well as untypical lesions of juxtacortical area. After other similar diseases were carefully ruled out, the patient was diagnosed as CLIPPERS and exhibited a good response to immunosuppressive therapy on the acute phase and after 6 months of follow up. CONCLUSIONS The results reported here broaden the known radiologic features for this rare disorder. A long-term follow-up to rule out other potential differential diseases is essential.

Abstract
OBJECTIVE Recently, long noncoding RNAs (lncRNAs) have attracted much attention for their roles in tumor progression. The aim of this study was to investigate the exact role of lncRNA UCA1 in the development of thyroid cancer (TC) and to explore the possible underlying mechanism. PATIENTS AND METHODS UCA1 expression in both TC cells and tissues was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Colony formation assay, cell proliferation, and transwell assay were conducted in vitro. Subsequent luciferase reporter gene assay was applied to investigate the underlying mechanism. Furthermore, the function of UCA1 in vivo was monitored as well. RESULTS UCA1 expression level in TC samples was significantly higher than that of corresponding normal tissues. After UCA1 was knocked down in vitro and in vivo, the proliferation, migration, and invasion of TC cells were significantly inhibited. Moreover, the expression of miR-497-3p was repressed after the knockdown of UCA1. Furthermore, miR-497-3p was directly targeted by UCA1. CONCLUSIONS Knockdown of UCA1 could inhibit TC cell proliferation and metastasis via sponging miR-497-3p. Our findings might offer a new therapeutic intervention for TC patients.

Abstract
Alzheimer's disease (AD), a progressive neurodegenerative disorder, is a leading global health concern for individuals and society. However, the potential mechanisms underlying the pathogenesis of AD have not yet been elucidated. Currently, the most widely acknowledged hypothesis is amyloid cascade owing to the brain characteristics of AD patients, including great quantities of extracellular β-amyloid (Aβ) plaques and intracellular neurofibrillary tangles (NFTs). Nevertheless, the amyloid cascade hypothesis cannot address certain pathologies that precede Aβ deposition and NFTs formation in AD, such as aberrant calcium homeostasis, abnormal lipid metabolism, mitochondrial dysfunction and autophagy. Notably, these earlier pathologies are closely associated with mitochondria-associated membranes (MAMs), the physical structures connecting the endoplasmic reticulum (ER) and mitochondria, which mediate the communication between these two organelles. It is plausible that MAMs might be involved in a critical step in the cascade of earlier events, ultimately inducing neurodegeneration in AD. In this review, we focus on the role of MAMs in the regulation of AD pathologies and the potential molecular mechanisms related to MAM-mediated pathological changes in AD. An enhanced recognition of the preclinical pathogenesis in AD could provide new therapeutic strategies, shifting the modality from treatment to prevention.

Abstract
Vascular endothelial cell (EC) and blood–brain barrier (BBB) dysfunction is the core pathogenesis of cerebral small vessel disease (CSVD). Moreover, animal experiments have shown the importance of connexin (Cx)-43 in EC and BBB function. In this study, we recruited 200 patients diagnosed with sporadic CSVD. Initially, we examined imaging scores of white matter hyperintensities (WMH), lacunar infarction (LI), and cerebral microbleeds (CMB). Additionally, we performed next-generation sequencing of the GJA1 gene (Cx43 coding gene) to examine correlation between these single-nucleotide polymorphisms and the burden and distribution of CSVD. Fourteen target loci were chosen. Of these, 13 loci (92.9%) contributed toward risk for cerebellar LI, one locus (7.1%) was shown to be a protective factor for lobar CMB after FDR adjustment. In conclusion, single-nucleotide polymorphisms in the GJA1 gene appear to affect the distribution but not severity of CSVD.

Abstract
The design and fabrication of a vertically stacked red-green-blue (RGB) light-emitting diode (LED) with novel, to the best of our knowledge, wavelength-selective distributed Bragg reflectors (DBRs) are demonstrated. The two DBRs are optimized to achieve selective reflectance in the RGB spectral region through theoretical calculations and simulation modeling. The insertion of optimal DBRs into the stack structure can effectively reflect downward emission from the upper chip without filtering the emission from the lower chips, thereby increasing the luminous efficiency for white emission with a color temperature range of 3000-8000 K by 1.6-7.4%. The optical performances of stacked devices with and without DBRs are thoroughly studied, verifying the effectiveness of the proposed wavelength-selective DBR structure.

Abstract
OBJECTIVE Tongue cancer is a common malignant tumor in the oral and maxillofacial region, most of which is squamous cell carcinoma. Cisplatin (DDP) is one of the chemotherapy drugs for patients with tongue squamous cell carcinoma (TSCC). However, DDP resistance has become a major obstacle to its clinical application. Our study aimed to investigate the effects of long non-coding RNA (lncRNA) KCNQ1 overlapping transcript 1 (KCNQ1OT1) on DDP resistance of tongue cancer and the underlying mechanism. PATIENTS AND METHODS The levels of KCNQ1OT1, miR-124-3p, and tripartite motif containing 14 (TRIM14) were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The maximum size of tumor (MTS) assay was used to detect the cell survival rates. Furthermore, the cell proliferation was detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. Transwell assay was performed to detect the cell migration and invasion. Western blot assay was used to detect the protein levels of Vimentin, N-cadherin, E-cadherin, and TRIM14. The functional targets of KCNQ1OT1 and miR-124-3p, miR-124-3p and TRIM14 were predicted by starBase 3.0 and TargetScan. The relationship between KCNQ1OT1 and miR-124-3p was confirmed by Dual-Luciferase reporter assay, RNA immunoprecipitation (RIP) and RNA pull-down. Further, the relationship between miR-124-3p and TRIM14 was verified by Dual-Luciferase reporter assay. Animal experiment revealed the effect of KCNQ1OT1 on DDP resistance of tongue cancer cells in vivo. RESULTS KCNQ1OT1 was upregulated in DDP-resistant tongue cancer tissues and cells, and mainly expressed in cytoplasm. Functionally, the knockdown of KCNQ1OT1 inhibited the survival rate, proliferation, migration, invasion, and EMT of the DDP-resistant tongue cancer cells. Of note, miR-124-3p acted as a target of KCNQ1OT1 and KCNQ1OT1 could reduce the expression of miR-124-3p. Moreover, miR-124-3p targeted TRIM14 and the downregulation of TRIM14 reduced the DDP resistance of tongue cancer cells. Importantly, KCNQ1OT1 regulated the TRIM14 expression by targeting miR-124-3p. Furthermore, KCNQ1OT1 knockdown reduced the DDP-resistant tumor growth and weight through the miR-124-3p/TRIM14 axis in vivo. CONCLUSIONS LncRNA KCNQ1OT1 promotes the DDP resistance of tongue cancer by sponging miR-124-3p to regulate TRIM14 expression.

Abstract
Abstract
Purpose
Cardiac amyloidosis (CA) is a major cause of mortality in patients with amyloidosis because it leads to heart failure and lethal arrhythmia. The present study was aimed to evaluate left ventricular (LV) global myocardial deformation in patients with CA of transmural late gadolinium enhancement (LGE) using tissue tracking MRI.
Materials and methods
Thirty-nine patients with CA, confirmed by cardiac MRI, and a biopsy of at least one involved organ were enrolled. According to LV ejection fraction (LVEF), they were divided into reduced LVEF (CArEF) and preserved EF (CApEF) groups. Thirty-nine normal controls were recruited (NC). Tissue tracking analysis was done based on cine MRI sequences. LV global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) were computed.
Results
GLS [CArEF vs. CApEF vs. NC: (−5.82±2.42) % vs. (−8.44±4.15) % vs. (−14.74±2.93)%], GCS [CArEF vs. CApEF vs. NC: (−9.47±2.96) % vs. (−15.01±1.81) % vs. (−19.86±2.30) %], and GRS [CArEF vs. CApEF vs. NC: (11.37±4.68) % vs. (20.61±6.27) % vs. (39.02±8.98) %] were all reduced in the CArEF and CApEF groups compared with healthy control subjects (all P<0.01). GCS and GRS in the CArEF group were reduced compared with the CApEF group (P<0.01). GLS, GCS, and GRS were also strongly correlated with LVEF (r=−0.77, −0.88, and 0.83, respectively; P<0.01). Furthermore, the optimal cutoff values to predict LVEF reduction were −9.31% (sensitivity 88%, specificity 97%) for GLS, −14.13% (sensitivity 96%, specificity 97%) for GCS, and 20.11% (sensitivity 90%, specificity 97%) for GRS.
Conclusion
MRI-based LV global deformation parameters could be a useful method to assess LV myocardial systolic function and predict LVEF reduction in patients with CA of transmural enhancement on LGE. The differences of GCS and GRS between the CArEF and CApEF groups may also reflect preserved contractile function of the mid- or/and subepicardial myocardium.

Abstract
BACKGROUND Numerous studies on acute ischemic stroke (AIS) have been conducted at low-altitude regions, and the related findings have been used to guide clinical management. However, corresponding studies at high altitude are few. This study aimed to analyse the clinical characteristics of AIS patients at high-altitude regions through a hospital-based comparative study between Tibet and Beijing. METHODS This study included the diagnoses of AIS patients from People's Hospital of Tibet Autonomous Region (PHOTAR) and Peking University First Hospital (PUFH) between 1 January 2014 and 31 December 2017, where data including patient demographics, treatment time, onset season, risk factors, infarction location, laboratory data, image examination results, treatments, and AIS subtype were collected and compared. Continuous and categorical variables were analysed with a two-sample t-test or Wilcoxon rank sum test and chi-square test, respectively. Significant risk factors were examined with binary logistic regression analysis. RESULTS In total, 236 and 1021 inpatients from PHOTAR and PUFH were included, respectively. The PHOTAR patients were younger than the PUFH patients (P < 0.001). Young adult stroke, erythrocytosis, and hyperhomocysteinemia were more frequent in PHOTAR patients (all P < 0.001). Other vascular risk factors, including hypertension, diabetes mellitus, hyperlipidaemia, smoking and alcohol consumption history, were less prevalent in PHOTAR patients than in PUFH patients. The rate of intravenous thrombolysis and the rate of within intravenous thrombolysis window time were also lower in PHOTAR patients (both P < 0.001). The PHOTAR group also tended to have anterior circulation infarction. Erythrocytosis and hyperhomocysteinemia were independent risk factors in PHOTAR, and young adults accounted for a larger proportion of stroke cases. CONCLUSION In Tibet, AIS patients were relatively younger, and anterior circulation infarctions were more common. Erythrocytosis and hyperhomocysteinemia may contribute to these differences. Here, young adult stroke also accounted for a higher proportion, and this may be associated with erythrocytosis. Our findings present the first hospital-based comparative study in Tibet and may contribute to policies for stroke prevention in this region.

Abstract
OBJECTIVE To explore the role of long noncoding ribonucleic acid (lncRNA) KCNQ1OT1 in the proliferation, apoptosis, and migration of ovarian cancer cells via Wnt/β-catenin. MATERIALS AND METHODS Ovarian cancer A2780 cells were divided into three groups, namely control group, KCNQ1OT1 overexpression group, and KCNQ1OT1 knockdown group. Next, the effect of KCNQ1OT1 on the proliferation of ovarian cancer A2780 cells was detected by cell counting kit-8 (CCK-8) assay. Wound healing assay and transwell assay were carried out to determine the influence of KCNQ1OT1 on the migration ability of ovarian cancer A2780 cells. The role of KCNQ1OT1 in the cell cycle of ovarian cancer A2780 cells was detected via flow cytometry. The impact of KCNQ1OT1 on the expression level of β-catenin protein in ovarian cancer A2780 cells was determined through Western blotting and fluorescence immunoassay. RESULTS The proliferation rate of cells was overtly decreased in KCNQ1OT1 knockdown group but significantly increased in KCNQ1OT1 overexpression group. The results of both wound healing and transwell assays showed that the migration ability of cells was reduced in KCNQ1OT1 knockdown group but raised in KCNQ1OT1 overexpression group. According to flow cytometry, the cell cycle was clearly arrested in the G0/G1 phase in KCNQ1OT1 knockdown group. The results of Western blotting and fluorescence immunoassay revealed that compared with that in control group, the expression level of β-catenin protein evidently declined in KCNQ1OT1 knockdown group, but it was notably elevated in KCNQ1OT1 overexpression group. CONCLUSIONS Increased lncRNA KCNQ1OT1 in ovarian cancer cells promotes the expression of β-catenin, thereby facilitating the proliferation and migration of ovarian cancer cells.

Abstract
BACKGROUND Sphingolipids mainly consist of ceramides (Cer), sphingomyelins (SM) and glycosphingolipids. Sphingolipids are related with coronary heart disease and metabolic disease, but there're few studies about cerebrovascular disease. The purpose was to detect sphingolipids in plasma of patients with large artery atherosclerosis (LAA) cerebrovascular disease and cerebral small vessel disease (CSVD) to explore the similarities and differences of pathogenesis of the two subtypes. METHODS 20 patients with LAA cerebrovascular disease, 20 patients with age-related CSVD, 10 patients with Fabry disease and 14 controls were enrolled from October 2017 to January 2019. Ultra-high performance liquid chromatography-quadruple-time-of-flight mass spectrometry/mass spectrometry was used to determine sphingolipids. Univariate combined with multivariate analysis was used for comparison. Receiver operating characteristic curves were used to determine sensitivities and specificities. RESULTS 276 sphingolipids were detected, including 39 Cer, 3 ceramide phosphates, 72 glycosphingolipids and 162 SM. (1) Cer (d36:3), Cer (d34:2), Cer (d38:6), Cer (d36:4) and Cer (d16:0/18:1) were increased in LAA; SM (d34:1), Cer (d34:2), Cer (d36:4), Cer (d16:0/18:1), Cer (d38:6), Cer (d36:3) and Cer (d32:0) were increased in age-related CSVD. (2) Cer (d36:4) and SM (d34:1) were increased in age-related CSVD compared with LAA. (3) Total trihexosyl ceramides were increased in Fabry group compared with control (P<0.05); SM (d34:1) was increased in Fabry group. CONCLUSIONS Ceramides are increased in both LAA and age-related CSVD, which may be related to similar risk factors and pathophysiological process of arteriosclerosis; SM is increased in both age-related CSVD and Fabry disease, suggesting that increased SM may be associated with CSVD. Glycosphingolipids, trihexosylceramides in particular, are increased in Fabry disease.

Abstract
AIMS To compare the cost-effectiveness of stereotactic ablative body radiation therapy (SABR) with radiofrequency ablation and surgery in adult patients with metastatic liver cancer and hepatocellular carcinoma (HCC). MATERIALS AND METHODS Two patient cohorts were assessed: liver oligometastases and HCC. For each patient cohort, a decision analytic model was constructed to assess the cost-effectiveness of interventions over a 5-year horizon. A Markov process was embedded in the decision model to simulate the possible prognosis of cancer. Data on transition probabilities, survival, side-effects, quality of life and costs were obtained from published sources and the SABR Commissioning through Evaluation (CtE) scheme. The primary outcome was the incremental cost-effectiveness ratio with respect to quality-adjusted life-years. The robustness of the results was examined in a sensitivity analysis. Analyses were conducted from a National Health Service and Personal Social Services perspective. RESULTS In the base case analysis, which assumed that all three interventions were associated with the same cancer progression rates and mortality rates, SABR was the most cost-effective intervention for both patient cohorts. This conclusion was sensitive to the cancer progression rate, mortality rate and cost of interventions. Assuming a willingness-to-pay threshold of £20 000 per quality-adjusted life-year, the probability that SABR is cost-effective was 57% and 50% in liver oligometastases and HCC, respectively. CONCLUSIONS Our results indicate a potential for SABR to be cost-effective for patients with liver oligometastases and HCC. This finding supports further investigation in clinical trials directly comparing SABR with surgery and radiofrequency ablation.

Abstract
UNLABELLED Caution is necessary when using symptom or physical examination findings to localize the osteoporotic vertebral fractures (VFs) attributable to the discrepant colocalized relationship. INTRODUCTION Whether the location of symptoms or physical examination findings delineates the appropriate spinal range for imaging has not been thoroughly investigated for VFs. The present study aims to analyze the consistency between the fractural vertebrae location and the location suggested by patient-reported pain or physical examination findings. METHODS This observational study, following a prospective design, enrolled 358 patients with VFs. The locations of two symptoms (patient-reported back pain [P-RBP], radiating pain [RP]) and findings from two physical examinations (spinal palpation tenderness [SPT], axial spinal percussion pain [ASPP]) were used to locate the VF segments identified using whole-spine magnetic resonance imaging (MRI). The percentage of agreements and kappa coefficient were calculated. RESULTS In 20.7% (74/358), the P-RBP site and VF segments were in the same location (kappa = 0.153); 21.2% (76/358) presented with concomitant RP in 93.4% (71/76) of whom the RP dermatome was colocalized with the VF segments (kappa = 0.924); 55.0% (197/358) and 23.2% (83/358) of patients presented with positive SPT and ASPP, respectively; and in 49.2% (97/197) and 96.4% (80/83) of patients with positive SPT (kappa = 0.435) and ASPP (kappa = 0.963), the positive finding and the VF segments were consistently colocalized. CONCLUSIONS The positive finding of RP or ASPP is useful in determining the spinal range for imaging tests, while an MRI scan covering the whole thoracic and lumbar spine is necessary in VF-suspected patients with P-RBP or positive SPT, indicating that caution is necessary when using symptoms or physical examination findings to localize VFs.

Abstract
BACKGROUND Extraventricular neurocytoma (EVN) is a rare neurocytoma occurring in the brain parenchyma outside the ventricular system that shares similar biological behaviors and histopathologic characteristics with central neurocytoma. Reports of EVN localized in the brainstem and cerebellum are relatively uncommon. In addition, few cases with radiotherapy as the only treatment have been reported and their outcomes were unclear. CASE DESCRIPTION We report a case of pathologically confirmed EVN of the brainstem and cerebellum in a 43-year-old male who presented with unprovoked nausea and dizziness. The patient received radiotherapy only and showed a favorable outcome during the 2-year follow-up period. CONCLUSIONS These results suggest that patients with EVN who are treated with radiotherapy without surgery may have a favorable prognosis.

Abstract
Background Hereditary spastic paraplegia is a heterogeneous group of clinically and genetically neurodegenerative diseases characterized by progressive gait disorder. Hereditary spastic paraplegia can be inherited in various ways, and all modes of inheritance are associated with multiple genes or loci. At present, more than 76 disease-causing loci have been identified in hereditary spastic paraplegia patients. Here, we report a novel mutation in SPAST gene associated with hereditary spastic paraplegia in a Chinese family, further enriching the hereditary spastic paraplegia spectrum. Methods Whole genomic DNA was extracted from peripheral blood of the 15 subjects from a Chinese family using DNA Isolation Kit. The Whole Exome Sequencing of the proband was analyzed and the result was identified in the rest individuals. RaptorX prediction tool and Protein Variation Effect Analyzer were used to predict the effects of the mutation on protein tertiary structure and function. Results Spastic paraplegia has been inherited across at least four generations in this family, during which only four HSP patients were alive. The results obtained by analyzing the Whole Exome Sequencing of the proband exhibited a novel disease-associated in-frame deletion in the SPAST gene, and this mutation also existed in the rest three HSP patients in this family. This in-frame deletion consists of three nucleotides deletion (c.1710_1712delGAA) within the exon 16, resulting in lysine deficiency at the position 570 of the protein (p.K570del). This novel mutation was also predicted to result in the synthesis of misfolded SPAST protein and have the deleterious effect on the function of SPAST protein. Conclusion In this case, we reported a novel mutation in the known SPAST gene that segregated with HSP disease, which can be inherited in each generation. Simultaneously, this novel discovery significantly enriches the mutation spectrum, which provides an opportunity for further investigation of genetic pathogenesis of HSP.

Abstract
The striped rice stem borer, Chilo suppressalis Walker, is one of the most destructive rice pests in Asia. Insecticidal crystal proteins (Cry toxins) produced by Bacillus thuringiensis are widely used as biopesticides or in developing transgenic crops for pest management. In this study, we tested the involvement of two newly cloned C. suppressalis cadherins (CsCAD3 and CsCAD4) in the toxicity of Cry1Ab/Ac, Cry2Aa and Cry1Ca. Our results showed that CsCAD4 was expressed highest in the midgut, whereas CsCAD3 was expressed highest in the epidermis. The feeding of double-stranded RNA specific to CsCAD3 and CsCAD4 respectively significantly suppressed the expressions of target gene. The knockdown of CsCAD3 significantly reduced the mortality of larvae to Cry1Ab/Ac, whereas knockdown of CsCAD4 significantly decreased the larval susceptibility to Cry2Aa. In contrast, reduced expressions of CsCAD3 or CsCAD4 were not interacted with larval susceptibility to Cry1Ca. Our results suggest that CsCAD3 and CsCAD4 function in Cry toxin toxicity and these findings will help us to better understand the action mechanism of Cry toxins in C. suppressalis.

Abstract
Extracellular vesicles (EVs) are small, double-membrane vesicles derived from erythrocytes, leukocytes, platelets, and cells of multiple tissues under physiologic or pathologic conditions. The role of EVs in stored RBC units is of great interest with respect to transfusion-related immunomodulation. The current study focuses on the quantity of EVs isolated from stored RBC units and their action on B cell-mediated immune responses. The in vitro experiment demonstrated that EVs exhibited a negative role in B cell survival, plasmacytic differentiation, and class switch recombination under LPS stimulation. Furthermore, LPS-induced antibody production was significantly decreased after EVs injection in vivo. Biochemical analysis revealed that EVs hampered the expression of Blimp-1 and IRF4 and the activation of NF-κB pathway in LPS-primed B cells. Overall, these data imply a vital role for EVs isolated from RBC units in B cell-mediated immune responses.

Abstract
Sensing-actuation systems can assist a bladder with lost sensation and weak muscle control. Here, we advance the relevant technology by integrating a soft and thin capacitive sensor with a shape memory alloy-based actuator to achieve a high-performance closed-loop configuration. In our design, sensors capable of continuous bladder volume detection and actuators with strong emptying force have been used. This integration has previously hindered performance due to large bladder volume changes. Our solution integrates sensing-actuation elements that are bladder compatible but do not interfere with one another, achieving real-time bladder management. The system attains a highly desirable voiding target of 71 to 100% of a rat's bladder with a volume sensitivity of 0.7 μF/liter. Our system represents an efficient voiding solution that avoids overfilling and represents a technological solution to bladder impairment treatment, serving as a model for similar soft sensor-actuator integration with other organs.

Abstract
pH-sensitive polyethylene glycol-conjugated urokinase nanogels (PEG-UK) is a new form of urokinase (UK) nanogels that could release UK at certain pH values. In our former study, we demonstrated that the pH value in the infarcted brain significantly declined to the level that could trigger the delivery of UK from PEG-UK. Thrombolysis is recommended as the first choice for ischemic stroke within the time window. However, it is common for the patients to miss the thrombolysis time window, which is one of the major causes of bad prognosis from ischemic stroke. It remains promising for seeking therapeutic approaches for ischemic stroke by investigating potential protective reagents delivered out of the usually thrombolysis time window. In this study, the protective effect of administration of PEG-UK outside the usual time window and the underlying mechanisms were investigated. PEG-UK was administrated 2 h and a half after ischemic stroke Delayed administration of PEG-UK significantly ameliorated the severity of neurological deficits of permanent middle cerebral occlusion (pMCAO) rats and reduced the infiltration of inflammatory cells and the concentration of interleukin 1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the brain tissues. The content of water and the leakage of Evans Blue (EB) in the PEG-UK group were also decreased. Maintenance of the expression of platelet-derived growth factor-C (PDGF-C) and inhibition of the upregulation of metalloproteinase proteins, low-density lipoprotein receptor-related protein (LRP), nuclear factor κB (NF-κB) p65 and cyclooxygenase-2 (Cox-2) were observed through western blotting and realtime PCR in the PEG-UK group. Besides, delayed administration of PEG-UK attenuated the up regulation of Caspase8 and Caspase9 and the cleavage of Caspase3 and poly (ADP-ribose) polymerase 1 (PARP1) in ischemic lesion sites. Moreover, PEG-UK treatment also inhibited the upregulation and phosphorylation of N-methyl-D-aspartic acid receptors (NMDARs), which has been revealed to play a vital role in mediating excito-neurotoxicity in ischemic stroke. In conclusion, through the inhibition of LRP/NF-κB/Cox-2 pathway, the Caspase cascade and activation of NMDARs, administration of PEG-UK outside the usual time window could still exert protective effects in pMCAO rats through the maintenance of the integrity of BBB and the inhibition of apoptosis and excito-neurotoxicity.

Abstract
Background and Purpose—
Studies on the prevalence and risk factors of white matter lesions (WMLs) in Tibetans living at high altitudes are scarce. We conducted this study to determine the prevalence and risks of WMLs in Tibetan patients without or with nonacute stroke.
Methods—
We undertook a retrospective analysis of medical records of patients treated at the People’s Hospital of Tibetan Autonomous Region and identified a total of 301 Tibetan patients without acute stroke. WML severity was graded by the Fazekas Scale. We assessed the overall and age-specific prevalence of WMLs and analyzed associations between WMLs and related factors with univariate and multivariate methods.
Results—
Of the 301 patients, 87 (28.9%) had peripheral vertigo, 83 (27.3%) had primary headache, 52 (17.3%) had a history of stroke, 36 (12.0%) had an anxiety disorder, 29 (9.6%) had epilepsy, 12 (4.0%) had infections of the central nervous system, and 3 (1.0%) had undetermined diseases. WMLs were present in 245 (81.4%) patients, and 54 (17.9%) were younger than 40 years. Univariate analysis showed that age, history of cerebral infarction, hypertension, the thickness of the common carotid artery intima, and plaque within the intracarotid artery were related risks for WMLs. Ordered logistic analysis showed that age, history of cerebral ischemic stroke, hypertension, male sex, and atrial fibrillation were associated with WML severity.
Conclusions—
Risk factors for WMLs appear similar for Tibetans residing at high altitudes and individuals living in the plains. Further investigations are needed to determine whether Tibetans residing at high altitudes have a higher burden of WMLs than inhabitants of the plains.

Abstract
Objective: To evaluate the cost-utility of different immunization strategies for rabies in China, and to provide a reference for determining the optimal immunization strategy. Methods: The system dynamics model was used to simulate the epidemic of canine rabies and a decision tree model was conducted to analysis different immune strategies. Relevant probabilities were obtained through literature search and on-site investigation. Sensitivity analysis was used to explore the important influenced factors. Results: At baseline, from a social perspective, 70% vaccination of dogs was the optimal strategy compared to current vaccination strategy (43% vaccination in dogs, human category-Ⅱ exposure vaccination/category-Ⅲ exposure vaccination combined with RIG). The total cost was 14 084 354 CNY, and the total utility value was 22 078 616.23 QALYs, and the incremental cost-utility ratio was-62 148 147 CNY/QALY; if human vaccination was considered, 55% vaccination of dogs combined with strategy one was the optimal strategy, its incremental cost-utility ratio was-444 620 557 CNY/QALY. The probability that an injured dog carries rabies virus was the most sensitive parameter. When it was greater than 0.005 03, strategy four was the optimal strategy. When it was less than 82/100 000, strategy one was the optimal strategy; when it was between 82/100 000 and 120/100 000, strategy two was the optimal strategy; when it was between 120/100 000 and 503/100 000, strategy two was the optimal strategy. Conclusion: It was conducive to increase the vaccination coverage of canine for the prevention and control of rabies.
