RESUMO

Objective: To study the clinical characteristics and classification of gastric neuroendocrine neoplasm(NEN) and prognostic factors of mixed adenoneuroendocrine carcinoma (MANEC) and gastric neuroendocrine carcinoma(NEC). Methods: A total of 148 gastric NENs were divided into type Ⅰ, type Ⅱ and type Ⅲ based on the classification of European Neuroendocrine Tumor Society (ENETS). Kaplan-Meier test and Cox regression model were used in univariate and multivariate survival analysis in 108 cases with pathological G3 gastric NEN. Results: In this study, the percentages of type Ⅰ, type Ⅱ and type Ⅲ were 25.0%(37), 3.4%(5) and 71.6%(106) respectively. Among type Ⅰ patients, 28(75.7%) lesions were located in gastric fundus or body, 29(78.4%) had bumps. Lymph node involvement was found in 4 (10.8%) patients. Twenty-six (70.3%) patients received endoscopic treatment and 11 (29.7%) with surgery. All 5 type Ⅱ patients presented lesions in gastric fundus or body, including 4 with ulcers, who were all treated by endoscope. Three type Ⅱ patients had gastrinoma, and 2 combined with multiple endocrine neoplasmⅠ. In type Ⅲ patients, 56(52.8%) showed ulcerative lesions. The majority of patients (102, 96.2%) had a single lesion, 94(88.7%) with lymph node or other organ metastasis. In this study, no deaths were reported in gastric NEN with a pathological grade of G1 or G2. The mortality rate was 38.9%(42/108) in patients with G3 NEN. Survival analysis suggested that age, metastasis of tumor were associated with poor prognosis (P=0.041, 0.025). Conclusions: Patients with gastric NEN have heterogenous clinical presentations according to gender, age, endoscopic features, infiltration and metastasis, and pathological grade. Aging and metastasis are negative prognostic factors of G3 gastric NEN.

RESUMO

OBJECTIVE: To clarify the role of LINC00675 in affecting the progression of clear cell renal cell carcinoma (ccRCC) and its potential mechanism, thus providing effective hallmarks and therapeutic targets for the clinical treatment of ccRCC. MATERIALS AND METHODS: Differentially expressed long non-coding RNAs (lncRNAs) in renal epithelial tissues and ccRCC tissues were searched by analyzing the dataset downloaded from The Cancer Genome Atlas (TCGA) and LINC00675 was selected. LINC00675 level in ccRCC cell lines was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Overexpression model of LINC00675 model in 786-O and 769-P cells was constructed by the transfection of pcDNA3.1(+)-LINC00675 (LV-LINC00675). Changes in proliferative, migratory, and invasive capacities of 786-O and 769-P cells overexpressing LINC00675 were assessed. At last, relative levels of ß-catenin, Vimentin, and N-cadherin in ccRCC cells overexpressing LINC00675 were detected by qRT-PCR and Western blot. RESULTS: LINC00675 was downregulated in ccRCC tissues and cell lines. Overexpression of LINC00675 attenuated proliferative, migratory, and invasive capacities of 786-O and 769-P cells. Downregulation in ß-catenin after overexpression of LINC00675, while Vimentin and N-cadherin levels did not change. CONCLUSIONS: LINC00675 is downregulated in ccRCC. Overexpression of LINC00675 attenuates ccRCC to proliferate, migrate, and invade by activating the Wnt/ß-catenin pathway.

RESUMO

Objective: To analyze the epidemiological history, clinical manifestations, treatment and the short-term prognosis of 31 cases of 2019 novel coronavirus(2019-nCoV) infection in children from six provinces (autonomous region) in northern China. Methods: A retrospective analysis of the epidemiological history, clinical symptoms, signs, laboratory examinations, chest imaging, treatment and the short-term prognosis of 31 cases of 2019-nCoV was conducted. The patients were diagnosed between January 25th, 2020 and February 21st, 2020 in 21 hospitals in 17 cities of six provinces(autonomous region) of Shaanxi, Gansu, Ningxia, Hebei, Henan and Shandong. Results: The age of the 31 children with 2019-nCoV infection was 7 years and 1 month (6 months -17 years). Nine cases (29%) were imported cases. Other 21 cases (68%) had contact with confirmed infected adults. One case (3%) had contact with asymptomatic returnees from Wuhan. Among the 31 children, 28 patients (90%) were family cluster cases. The clinical types were asymptomatic type in 4 cases (13%), mild type in 13 cases (42%), and common type in 14 cases (45%). No severe or critical type existed. The most common symptom was fever (n=20, 65%), including 1 case of high fever, 9 cases of moderate fever, 10 cases of low fever. Fever lasted from 1 day to 9 days. The fever of fifteen cases lasted for ≤3 d, while in other 5 cases lasted > 3 d. Other symptoms included cough (n=14, 45%), fatigue (n=3, 10%) and diarrhea (n=3, 9%). Pharyngalgia, runny nose, dizziness, headache and vomiting were rare. In the early stage, the total leukocytes count in peripheral blood decreased in 2 cases (6%), the lymphocytes count decreased in 2 cases (6%), and the platelet count increased in 2 cases (6%).Elevation of C-reactive protein (10%, 3/30), erythrocyte sedimentation rate(19%,4/21), procalcitonin(4%,1/28), liver enzyme(22%, 6/27) and muscle enzyme (15%, 4/27) occurred in different proportions. Renal function and blood glucose were normal. There were abnormal chest CT changes in 14 cases, including 9 cases with patchy ground glass opacities and nodules, mostly located in the lower lobe of both lungs near the pleural area. After receiving supportive treatment, the viral nucleic acid turned negative in 25 cases within 7-23 days. Among them, 24 children (77%) recovered and were discharged from hospital. No death occurred. Conclusions: In this case series, 2019-nCoV infections in children from six provinces (autonomous region) in northern China are mainly caused by close family contact. Clinical types are asymptomatic, mild and common types. Clinical manifestations and laboratory examination results are nonspecific. Close contact history of epidemiology, nucleic acid detection and chest imaging are important bases for diagnosis. After general treatment, the short-term prognosis is good.

RESUMO

Melanogenesis, migration, and proliferation of melanocytes are important factors that determine the hair colors of mammals. MicroRNAs (miRNAs) have been shown to be closely relation to these processes. In melanocytes of alpacas, insulin-like growth factor 1 (IGF1) has been shown to improve melanogenesis through the cyclic AMP (cAMP) pathway. miR-379 was predicted to target insulin-like growth factor (IGF) receptor 1 (IGF1R), which binds to IGF1. Therefore, we hypothesized that miR-379 could mediate melanogenesis, migration, and proliferation of melanocytes. Here, we report that miR-379 was highly expressed in alpaca melanocytes. Subsequent overexpression of miR-379 in alpaca melanocytes led to the generation of the phenotype of melanogenesis, proliferation and migration. In addition, the expression of genes related to these phenotypes in melanocytes were detected. Our results showed that miR-379 targets IGF1R in melanocytes. The overexpression of miR-379 stimulated dendrite extension or elongation and limited the perinuclear distribution of melanin, but inhibited melanogenesis via cAMP response element (CRE) binding protein (CREB) /microphthalmia-associated transcription factor (MITF) pathway. miR-379 attenuated melanocyte migration by downregulating the focal adhesion kinase (FAK), and enhanced melanocyte proliferation by upregulating protein kinase B (AKT). These observations suggest the involvement of miR-379 in the physiological regulation of melanocytes, mediated by targeting IGF1R on insulin receptor (IR) compensation and subsequent crosstalk.

RESUMO

Objective: To characterize the clinical features of patients with Behcet's uveitis. Methods: Retrospective case series study. Medical records of patients who were diagnosed as Behcet's uveitis in Peking Union Medical College Hospital between January 1998 and November 2015 were retrospectively reviewed. Information about the clinical manifestation, complication, best corrected visual acuity (logarithm of the minimum angle of resolution) and medication was collected. The correlation of visual acuity and the disease course, as well as inflammation relapse times before and after biological agents applied was analyzed. Chi square test and Wilcoxon signed-rank test were applied for statistical analysis. Results: A total of 132 patients (233 eyes) with Behcet's uveitis were included, among which 104 (78.8%) were male and 28 (21.2%) were female, with statistically significant difference (χ(2)=43.76, P<0.01). The average age at the onset of uveitis was (28.9±8.7) years, with most patients at 21-40 years (102 cases, 77.3%). Oral aphthae (132 cases, 100.0%) were the most frequent extraocular manifestations, followed by dermatologic lesions (103 cases, 78.0%), genital ulcers (90 cases, 68.2%), arthritis (44 cases, 33.3%) and positive pathergy test (39 cases, 29.5%). Ocular involvement was bilateral in 76.5% (101 cases) of the patients, and panuveitis was the most common type (110 cases, 83.3%). Complications were seen in 80.7% (188/233) of the eyes, with cataract (58.8%, 137/233) and macular edema (59.1%, 114/193) being the most common anterior and posterior segment complications, respectively. At the eighth year of uveitis, best corrected visual acuity decreased to less than 0.3 in 20.9% (9/43) of the eyes, and more than 1.0 in 39.5% (17/43) of the eyes. A combination of glucocorticoids and immune modulators remained the first line therapy (97.0%, 128/132) for Behcet's uveitis. For 16 refractory cases, an addition of biological agents significantly reduced the inflammation relapse [0.5 (0.0, 1.5) times per year vs. 4.0 (1.0, 5.5) times per year, Z=-2.81, P=0.005]. Conclusions: Behcet's uveitis mainly affects working-age males and manifests as bilateral panuveitis. Complications are commonly seen in uveitic eyes. Patients' visual acuity is significantly impaired. A combination of glucocorticoids and immune modulators is effective for most patients, but for refractory cases, an addition of biological agents provides better effects.

RESUMO

OBJECTIVE: This study aimed to elucidate the role of decorin, a small leucine-rich proteoglycan, in the degradation of cartilage matrix during the progression of post-traumatic osteoarthritis (PTOA). METHODS: The destabilization of the medial meniscus (DMM) surgery was applied to 3-month-old decorin-null and inducible decorin knockout mice to induce PTOA. The resulted OA phenotype was evaluated by assessing joint morphology and sulfated glycosaminoglycan (sGAG) staining via histology (n = 6/group), surface collagen fibril nanostructure via scanning electron microscopy (n = 4), tissue modulus via atomic force microscopy-nanoindentation (n ≥ 5) and subchondral bone structure via micro-computed tomography (n = 5). Femoral head cartilage explants from wild-type and decorin-null mice were subjected to the stimuli of inflammatory cytokine interleukin-1ß (IL-1ß) in vitro (n = 6). The resulting chondrocyte response to IL-1ß and release of sGAGs were quantified. RESULTS: In both decorin-null and inducible decorin knockout mice, the absence of decorin results in accelerated sGAG loss and formation of highly aligned collagen fibrils on cartilage surface relative to the control (p < 0.05). Also, decorin-null mice developed more salient osteophytes, illustrating more severe OA. In cartilage explants, with IL-1ß treatment, loss of decorin did not alter the expression of either anabolic or catabolic genes. However, a greater proportion of sGAGs was released to the media from decorin-null explants, in both live and devitalized conditions (p < 0.05). CONCLUSION: In PTOA, decorin delays the loss of fragmented aggrecan and fibrillation of cartilage surface, and thus, plays a protective role in ameliorating cartilage degeneration.

RESUMO

Severe and critical coronavirus pneumonia 2019 (COVID-19) often occurs in elder patients with multiple comorbidities, and severe hypoxemia events are an important factor in the deterioration of some cases. The critical type of COVID-19 could progress to acute respiratory distress syndrome and multi-organ dysfunction, which are the most important causes of death. Early start with non-invasive ventilation (NIV) against the possible physiological abnormalities could be helpful to improve prognosis. Close monitoring of oxygenation, reducing patients' oxygen consumption, active psychological intervention, and rapidly dealing with severe hypoxemia events are the key factors for the successful treatment of NIV. In addition, active adjuvant therapy is also important, such as correcting coagulation dysfunction, providing proper nutritional support, accurate volume control, and safe individualized blood glucose monitoring and control.

RESUMO

BACKGROUND AND PURPOSE: Accurate differentiation between glioblastoma and solitary brain metastasis is of vital importance clinically. This study aimed to investigate the potential value of the inflow-based vascular-space-occupancy MR imaging technique, which has no need for an exogenous contrast agent, in differentiating glioblastoma and solitary brain metastasis and to compare it with DSC MR imaging. MATERIALS AND METHODS: Twenty patients with glioblastoma and 22 patients with solitary brain metastasis underwent inflow-based vascular-space-occupancy and DSC MR imaging with a 3T clinical scanner. Two neuroradiologists independently measured the maximum inflow-based vascular-space-occupancy-derived arteriolar CBV and DSC-derived CBV values in intratumoral regions and peritumoral T2-hyperintense regions, which were normalized to the contralateral white matter (relative arteriolar CBV and relative CBV, inflow-based vascular-space-occupancy relative arteriolar CBV, and DSC-relative CBV). The intraclass correlation coefficient, Student t test, or Mann-Whitney U test and receiver operating characteristic analysis were performed. RESULTS: All parameters of both regions had good or excellent interobserver reliability (0.74∼0.89). In peritumoral T2-hyperintese regions, DSC-relative CBV (P < .001), inflow-based vascular-space-occupancy arteriolar CBV (P = .001), and relative arteriolar CBV (P = .005) were significantly higher in glioblastoma than in solitary brain metastasis, with areas under the curve of 0.94, 0.83, and 0.72 for discrimination, respectively. In the intratumoral region, both inflow-based vascular-space-occupancy arteriolar CBV and relative arteriolar CBV were significantly higher in glioblastoma than in solitary brain metastasis (both P < .001), with areas under the curve of 0.91 and 0.90, respectively. Intratumoral DSC-relative CBV showed no significant difference (P = .616) between the 2 groups. CONCLUSIONS: Inflow-based vascular-space-occupancy has the potential to discriminate glioblastoma from solitary brain metastasis, especially in the intratumoral region.

RESUMO

Objective: To explore the occurrence of cognitive impairment in Chinese heart failure (HF) patients and it's impact on prognosis. Methods: In this prospective observational study, a total of 990 HF patients were enrolled from 24 hospitals in China during December 2012 to November 2014. All patients were administrated with the interview-format Montreal Cognitive Assessment (MoCA), according to which they were divided into MoCA<26 (with cognitive impairment) group and MoCA≥26 (without cognitive impairment) group. Baseline data were collected and a 1-year follow up was carried out. Univariate and multivariate logistic or Cox regression were performed for 1-year outcomes. Results: Cognitive impairment was evidenced in 628 patients (63.4%) and they were more likely to be older, female, and with higher proportion of New York Heart Association(NYHA) class Ⅲ-Ⅳ, chronic obstructive pulmonary disease (COPD), ischemic heart disease, while body mass index (BMI), education level, and medical insurance rate were lower (all P<0.05) as compared to patients in MoCA≥26 group. The rate of percutaneous intervention, device implantation, cardiac surgery and evidence-based medications were significantly lower in MoCA<26 group than in MoCA≥26 group (all P<0.05). During the 1-year follow up, patients in the MoCA<26 group had higher all-cause mortality (10.2%(64/628) vs. 2.2%(8/362), P<0.01), cardiovascular mortality (5.9%(37/628) vs. 0.8%(3/362), P<0.01) and major adverse cardiac and cerebrovascular events (MACCE) (9.6%(60/628) vs. 2.5%(8/362), P<0.01) than patients in the MoCA≥26 group. In univariate regression, MoCA<26 was associated with increased all-cause mortality (HR(95%CI):4.739(2.272-9.885), P<0.01), cardiovascular mortality (HR(95%CI):7.258(2.237-23.548), P=0.001) and MACCE (OR(95%CI):4.143(2.031-8.453), P<0.01). After adjustment by multivariate regression, MoCA<26 was indicated as an independent risk factor for all-cause mortality (HR(95%CI): 6.387(2.533-16.104), P<0.01), cardiovascular mortality (HR(95%CI): 10.848(2.586-45.506), P=0.001) and MACCE (OR(95%CI): 4.081(1.299-12.816), P=0.016), while not for re-hospitalization for HF (OR(95%CI):1.010(0.700-1.457), P=0.957). Conclusions: Cognitive impairment is common in HF patients,and it is an independent prognostic factor for 1-year outcomes. Routine cognitive function assessment and active intervention are thus recommended for HF patients.

RESUMO

Objective: To compare the difference of the clinical and laboratory characteristics between γδ T-cell large granular lymphocyte leukemia (γδT-LGLL) and αß T-cell large granular lymphocyte leukemia (αßT-LGLL) . Methods: The clinical and laboratory characteristics of 17 patients with γδT-LGLL and 91 patients with αßT-LGLL in the department of therapeutic center of anemia of enrolled in our hospital from January 2009 to January 2019 were retrospectively analyzed. Results: The median age of the 17 patients with γδT-LGLL was 54 years (range, 25-73 years) , the most common presenting symptom was anemia. In comparison with αßT-LGLL patients, splenomegaly was common (41% and 44%, respectively) , whereas hepatomegaly (12% and 5%, respectively) and lymphadenopathy (6% and 8%, respectively) were rare. The positive rates of antinuclear antibody (59% and 45%, respectively) were high, whereas the positive rates of rheumatoid factor (6% and 10%, respectively) were rare for both groups. There were no differences on peripheral blood counts between the two groups. However, γδT-LGLL patients were found to be predominantly expressed a CD4(-)/CD8(-) phenotype. Steroid therapy with prednisone was used alone as first-line therapy for 1 patient. Cyclosporin A (CsA) was used alone as first-line therapy for 3 patients. CsA in combination with steroids were administered in 13 patients. After 4 months treatment, 2 patients acquired complete response, 4 patients acquired partial response, the overall response was 35%. Conclusion: γδT-LGLL is a rare mature T-lymphocyte proliferative disease. Clinical and laboratory characteristics were quite similar for γδT-LGLL in compare with αßT-LGLL. γδT-LGLL predominantly expressed a CD4(-)/CD8(-) phenotype. The data presented here indicate the CsA is an effective option for the first-line treatment of γδT-LGLL.

RESUMO

BACKGROUND: Macrophages may be important in chronic rejection after organ transplantation. This study aimed to investigate the possibility of depleting macrophages for a certain amount of time to alleviate chronic rejection in a heart transplant model of Fischer to Lewis rats. METHODS: Clodronate liposome was injected abdominally to deplete macrophages for 2 time frames. The expression levels of ectodysplasin 1, arginase 1 (Arg1), chitinase-like lectin (Ym1), interferon gamma, tumor necrosis factor α (TNF-α), smooth muscle α-actin (α-SMA), monocyte chemoattractant protein 1 (MCP-1), and interleukin 10 (IL-10) were detected. RESULTS: 1. The expression levels of α-SMA, interferon gamma, TNF-α, and MCP-1 and the transformation of peripheral T cells were lower after macrophage depletion for 2 or 4 weeks. 2. The expression levels of α-SMA, TNF-α, and MCP-1 and the transformation of peripheral T cells were even lower after 4 weeks compared with 2 weeks, except for interferon gamma. 3. A higher level of expression of Arg1 and Ym1 after macrophage depletion for 2 weeks was observed. 4. A higher level of expression of IL-10 after macrophage depletion for 2 weeks, but not 4 weeks, was also observed. CONCLUSIONS: Macrophage clearance after heart transplantation alleviated chronic rejection probably via M2 polarization of regenerated macrophages, reduced T-lymphocyte proliferation, and changed the expression levels of interferon gamma, TNF-α, MCP-1, and IL-10.

RESUMO

Tumor-infiltrating immune cells play critical roles in immune-mediated tumor rejection and/or progression, and are key targets of immunotherapies. Estimation of different immune subsets becomes increasingly important with the decreased cost of high-throughput molecular profiling and the rapidly growing amount of cancer genomics data. Here, we present Tumor IMmune Estimation Resource (TIMER), an in silico deconvolution method for inference of tumor-infiltrating immune components. TIMER takes bulk tissue gene expression profiles measured with RNA-seq or microarray to evaluate the abundance of six immune cell types in the tumor microenvironment: B cell, CD4+ T cell, CD8+ T cell, neutrophil, macrophage, and dendritic cell. We further introduce its associated webserver for convenient, user-friendly analysis of tumor immune infiltrates across multiple cancer types.

RESUMO

Objective: To investigate the breakthrough incidence of invasive fungal disease(IFD) and side effects of posaconazole as primary prophylaxis during induction chemotherapy for acute myeloid leukemia(AML). Methods: A total of 206 newly diagnosed AML patients admitted to our department during January 2016 and December 2018 were enrolled in the study. Exclusive criteria were as followings including patients diagnosed as acute promyelocytic leukemia; those who received intravenous antifungal therapy after admission or had history of IFD one month before induction chemotherapy, or those with functional insufficiency of vital organs and those older than 65. Forty-seven patients received posaconazole (posaconazole group), 61 cases received voriconazole (voriconazole group) and 98 cases did not receive any prophylaxis (control group) during induction chemotherapy. Prophylactic efficacy and safety between posaconazole and voriconazole were compared. Results: During induction chemotherapy, five possible cases of IFD occurred in posaconazole group (10.6%); while 11 cases (18.0%) were in voriconazole group including 7 possible, 3 probable and 1 proven. Thirty-five cases (35.7%) in control group were diagnosed as IFD including 19 possible, 11 probable and 5 proven ones. The incidences of IFD in posaconazole and voriconazole group were significantly lower than that in control group (P<0.05). The difference of posaconazole group and voriconazole group was not significant (P>0.05). The reported adverse events in posaconazole group were significantly lower than those in voriconazole group [12.8%(6/47) vs. 32.8%(20/61), P<0.05]. Conclusions: Posaconazole and voriconazole decrease IFD as primary prophylaxis during induction chemotherapy in patients with AML. The prophylactic effect of IFD with posaconazole is similar as voriconazole, but posaconazole shows better safety.

RESUMO

To investigate the clinical manifestations and risk factors in patients with systemic lupus erythematosus (SLE) and cancers. From October 2010 to February 2019, 5 566 SLE patients hospitalized in the First Affiliated Hospital of Zhengzhou University were enrolled. A total of 69 cancer patients were identified, and the clinical characteristics and previous treatment were analyzed. Cervical carcinoma (21.74%, 15/69) and thyroid cancer (21.74%, 15/69) were the most common types of cancer. Most cancers were diagnosed in SLE patients with an age 40~50 years. The disease duration of SLE was from 60~120 months. SLE patients without cancers were usually diagnosed between 20~30 years with duration of symptoms less than 12 months. As to the previous treatment of SLE, the uses of glucocorticoid, cyclophosphamide, methotrexate and azathioprine were comparable between patients with cancers and without (P>0.05). However, the use of hydroxychloroquine was more frequent in SLE patients than in patients with cancers (P<0.01). Correlation analysis revealed significant correlation between disease course of SLE (OR=4.25, 95%CI 1.79~10.01,P<0.001), hydroxychloroquine (OR=0.26, 95%CI 0.12~0.59,P<0.001) and cancer risk. Long disease course may be a risk factor for SLE patients to develop cancer, whereas hydroxychloroquine could be a protective factor.
