OBJECTIVETo identify risk factors of hepatocellular carcinoma (HCC) in cirrhotic patients with chronic hepatitis B (CHB).

METHODSA total of 715 cirrhotic patients with CHB were recruited from the Zhongshan Hospital Affiliated to Fudan University and enrolled in this case-control study between January 2009 and September 2014. All participants were Chinese Han residing in Shanghai and the surrounding areas. The patients were divided into a cirrhosis group (n =281) and a HCC group (n=434). History of hepatitis B infection and HCC, as well as clinical data from serological, imaging and pathological examinations were collected for analysis.SPSS software, version 19.0, was used for all statistical comparisons.

RESULTSSingle factor analysis indicated that development of HCC in cirrhotic patients with CHB was significantly associated with male sex, age of 50 years or more, family history of HCC, alcohol consumption,fatty liver, detectable levels of hepatitis B virus (HBV) DNA, and history of HBV infection without effective antiviral treatment. Multivariate logistic regression analysis indicated that age of 50 years or more (P =0.005, odds ratio [OR] =1.766), history of alcohol consumption (P =0.002, Or = 2.570), family history of HCC (P =0.014, Or = 2.268), fatty liver (P =0.023, Or = 3.390), and history of HBV infection without effective antiviral treatment (P < 0.001,Or = 5.389) were risk factors of HCC.The risk factors for development of HCC in cirrhotic patients with hepatitis B after achieving sustained virologic suppression (SVS) were family history of HBV infection (P =0.014, Or = 2.537), family history of HCC (P =0.037,Or = 3.339) and fatty liver (P =0.018, Or = 11.646).

CONCLUSIONRisk factors of HCC in cirrhotic patients with CHB include age,drinking history,family history of HCC, fatty liver, and ineffective antiviral treatment of CHB.Family history of HBV infection or HCC, and fatty liver disease, were significantly associated with HCC development after SVS in patients with hepatitis B-related cirrhosis.

Objective:To investigate expression profiles of the plasma exosomal miRNAs of the chronic hepatitis B (CHB) patients with persistently normal alamine aminotransferase (PNALT) for the first time and try to find exosomal miRNAs which could reflect liver inflammation better.Methods:Five CHB patients with liver tissue inflammation grade ≥A2 of PNALT and 5 CHB patients with liver tissue inflammation grade ＜A2 of PNALT were enrolled and their blood samples were collected.The exosomes were extracted from these blood samples and measured by electron microscope to determine the extraction effect.The exosomal miRNAs were extracted and sent for high throughput sequencing,and the expression of exosomal miRNAs in the 2 groups of patients was analyzed.Results:Under the electron microscope,exosomes were small membranous vesicles with 30-100 nm in diameter.The peak value of particle size ranged from 10 to 100 nm.High throughput sequencing showed that there were 591 differentially expressed exosomal miRNAs between the 2 groups.Compared with the control group,18 exosomal miRNAs were up-regulated and 6 exosomal miRNAs were down-regulated in PNALT patients with the liver tissue inflammation grade ≥ A2.Conclusion:Exosomal miRNAs in the CHB patients with PNALT who have the different grades of liver inflammation are differently expressed.Some of the differently expressed exosomal miRNAs are expected to be sensitive biomarkers for timely assessment of liver inflammation in the CHB patients with PNALT.

Background: Voltage-gated sodium channel 1.5 (Nav1.5) potentially promotes the migratory and invasive behaviors of colon cancer cells. Hitherto, the prognostic significance of Nav1.5 expression remains undetermined. The present study aimed to explore the associations of Nav1.5 expression with clinical outcomes and estrogen receptor-β (ER-β) expression in non-metastatic colon cancer patients receiving radical resection. Methods: A total of 269 consecutive patients with pathologically confirmed stages Ⅰ–Ⅲ colon cancer who under-went radical resection were selected. Nav1.5 and ER-β expression was detected by using immunohistochemistry (IHC) on tissue microarray constructed from paraffin-embedded specimens. IHC score was determined according to the percentage and intensity of positively stained cells. Statistical analysis was performed with the X-tile method, k coef-ficient, Chi square test or Fisher's exact test, logistic regression, log-rank test, and Cox proportional hazards models. Results: We found that Nav1.5 was commonly expressed in tumor tissues with higher mean IHC score as compared with matched tumor-adjacent normal tissues (5.1 ± 3.5 vs. 3.5 ± 2.7, P < 0.001). The high expression of Nav1.5 in colon cancer tissues was associated with high preoperative carcinoembryonic antigen level [odds ratio (OR) = 2.980;95% confidential interval (CI) 1.163–7.632; P = 0.023] and high ER-β expression (OR = 2.808; 95% CI 1.243–6.343;P = 0.013). Log-rank test results showed that high Nav1.5 expression contributed to a low 5-year disease-free survival (DFS) rate in colon cancer patients (77.2% vs. 92.1%, P = 0.048), especially in patients with high ER-β expression tumor (76.2% vs. 91.3%, P = 0.032). Analysis with Cox proportional hazards model demonstrated that high Nav1.5 expression [hazard ratio (HR) = 2.738; 95% CI 1.100–6.819; P = 0.030] and lymph node metastasis (HR = 2.633; 95% CI 1.632–4.248; P < 0.001) were prognostic factors for unfavorable DFS in colon cancer patients. Conclusions: High expression of Nav1.5 was associated with high expression of ER-β and indicated unfavorable oncologic prognosis in patients with non-metastatic colon cancer.

Objective The aim of this study was to evaluate the glioma using the variety of functional magnetic resonance imaging( fMRI) ,and to perform a more accurate preoperative diagnosis of gliomas. Methods Thirty - five patients with gliomas confirmed by pathology were examined by magnetic resonance imaging (MRI)and functional MRI. Rapid diffusion coefficient(D?),Slow diffusion coefficient(D),perfusion fraction ( f) and distribution diffusion coefficient ( DDC ) in the intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) were analyzed statistically. Results The mean values of D?,D,f and DDC in the IVIM se-quence of the patients with high-grade of gliomas were statistically significant when compared to the IVIM values of the contralateral normal brain tissues(P<0. 05). Conclusion A variety of magnetic resonance functional im-aging sequences are used to analyze gliomas,which can avoid tumor heterogeneity and improve the recognition a-bility and accuracy of magnetic resonance imaging in high grade gliomas.

Insomnia, as the most common sleep disorder in the population, is often accompanied by depression, anxiety and other mental diseases, which can lead to impaired social and occupational functions as well as decreased quality of life. There is growing evidence that insomnia may be a risk factor for stroke. On the other hand, the incidence of insomnia in stroke patients is significantly higher than that in the general population. Correctly understanding the bidirectional relationship between insomnia and stroke can make clinicians pay more attention to insomnia and its treatment, and increase clinical benefit in patients with stroke and insomnia.

Objective To investigate the relationship between daily intake of B vitamins(vitamins Bl,B2,B6 and niacin)and chronic constipation and chronic diarrhea.Methods Data of 3 durations(2005-2006,2007-2008 and 2009-2010)from National Health and Nutrition Examination Survey(NHANES)database were collected and retrospectively analyzed.For the 13 788 participants,their intake of vitamin B1,B2,B6,and niacin were assessed through a 24-hour dietary recall interview.Multivariate logistic regression analysis was employed to explore the correlation between B vitamins and chronic constipation and chronic diarrhea.Additionally,sensitivity analysis and curve fitting correlation analysis were conducted to further elucidate the observed relationships.Results Among the subjects who were enrolled in the study,2 520(18.28％)were diagnosed with chronic constipation,while 2 138(15.51％)were diagnosed with chronic diarrhea.Multivariate logistic regression analysis and sensitivity analysis indicated linear correlations between the intake of vitamin B1,niacin and vitamin B6 and the occurrence of chronic constipation and chronic diarrhea.An increase in the daily intake of these nutrients potentially reduced the risk of chronic constipation,but also increased the risk of chronic diarrhea(P＜0.05).Conclusion Daily intake of vitamins B1,B2,B6 and niacin is correlated with the occurrence of chronic constipation and chronic diarrhea.

Objective:To investigate the clinicopathological characteristics of the T cell lymphomas with CD20 expression, and to better understand this rare entity.Methods:Two-hundred cases of T-cell lymphoma diagnosed in the Department of Pathology of the Affiliated Hospital of Qingdao University from November 2016 to February 2020 were examined, and 5 cases of CD20-positive T-cell lymphomas were identified and included. Combined with clinical data and review of the literature, the clinicopathological characteristics of the disease were analyzed.Results:The five patients were all male, and had an average age of 56 years (range, 47 to 64 years). There were 2 cases of monomorphic epitheliotropic intestinal T-cell lymphoma, 2 cases of mycosis fungoides (1 case was plaque stage and the other was tumor stage) and 1 case of indolent T-cell lymphoproliferative disorder of the gastrointestinal tract. Immunohistochemistry showed that all 5 cases expressed multiple T cell markers (CD3/CD4/CD5/CD7/CD8) and only one of B cell markers (CD20). Three of the 5 cases were negative for CD20 at the first diagnosis, while CD20 was diffusely positive on the second biopsy from the recurrence or progression of the disease, without expression of CD79a or PAX5. Epstein-Barr encoding region (EBER) in situ hybridization was negative in all 5 cases. T-cell receptor gene analysis showed monoclonal rearrangement of β or/and δ chains;Ig rearrangements were all polyclonal. None of the five patients were treated with rituximab, and 4 patients survived with disease and 1 patient survived without disease at the end of follow-up. Among them, the patient with mycosis fungoides at the cancerous stage has progressed rapidly and had poor quality of life.Conclusions:CD20-positive T-cell lymphoma is extremely rare. Its prognosis is closely related to the type of T-cell lymphoma, clinical stage and initial therapeutic effect. However, the expression of CD20 indicates the recurrence or progression of the disease, and the prognosis is relatively poor. When CD3 expression is absent in T-cell lymphoma, it is easy to be misdiagnosed as B-cell lymphoma. The combination of multiple immunohistochemical antibodies and molecular detection can improve the accuracy of diagnosis.

Objective Abnormalities of lipid profile were considered as risk factors of hemorrhage after ischemic stroke. We aimed to determine the relationship between lipid levels and bleeding in minor stroke or transient ischemic attack (TIA) patients receiving antiplatelet therapy. Methods Serum total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglyceride were tested in a subgroup of 3044 consecutive patients from Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial. Patients were randomized to clopidogrel plus aspirin group or single aspirin group. The primary endpoint was any bleeding within 90 days. The secondary endpoint was severe bleeding according to the Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries (GUSTO) definition. Cox proportional hazards models were used to assess the associations of lipid levels and outcomes. Results A total of 59 (1.9％) bleeding events occurred at 90 days. High-density lipoprotein cholesterol (adjusted HR=2.16; 95％CI 1.17-4.00, P=0.014) and age (adjusted HR=1.04;95％CI 1.01-1.06, P=0.006) were significantly associated with any bleeding. High-density lipoprotein cholesterol was also associated with severe bleeding (adjusted HR=3.05;95％CI 1.39-6.68, per 1 mmol/L increase). No correlations between outcomes and levels of total cholesterol, low-density lipoprotein cholesterol and triglyceride were found. There was no interaction of any lipid component level with randomized antiplatelet therapy. Conclusions Elevated high-density lipoprotein cholesterol is independently associated with any bleeding and severe bleeding in the patients with acute minor stroke or high-risk TIA on antiplatelet therapy.

Objective: To investigate the relationship between dietary polyunsaturated fatty acid (PUFA) intake and blood lipid, C-reactive protein (CRP) and homocysteine (Hcy) in patients with acute ischemic stroke or transient ischemic attack (TIA). Methods: Patients with acute ischemic stroke or TIA were enrolled consecutively from Nanjing Stroke Registry Program. The total dietary PUFA intake level was assessed by the food semi-quantitative frequency questionnaire. Venous blood samples were collected in the morning of the day after admission to the hospital to detect the levels of serum total cholesterol, triacylglycerol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, Hcy, and CRP. According to the median level of total PUFA intake, the patients were divided into low PUFA group and high PUFA group. The relationship between PUFA intake and blood lipid, CRP and Hcy was analyzed by Spearman correlation analysis, and multiple linear regression analysis was used to determine the independent correlation. Results: A total of 170 patients (85.1%) with acute ischemic stroke and 31 patients with TIA (14.9%) were enrolled. Their age was 62.9±14.1 years, 143 were males (71.1%), and the median PUFA daily intake was 12.8 g (interquartile range: 8.05-17.5 g). Compared with the high PUFA group (n=100), patients in the low PUFA group (n=101) were older, serum high-density lipoprotein cholesterol levels were lower, and CRP and Hcy levels were higher. The above differences were statistically significant (all P<0.05). Spearman correlation analysis showed that total dietary PUFA intake was significantly negatively correlated with the serum CRP (r=-0.24, P=0.001) and Hcy (r=-0.17, P=0.013) levels, and there was no significant correlation with the blood lipid levels. Multiple linear regression analysis showed that CRP was significantly negatively correlated with PUFA intake after adjusting for confounding factors (B=-0.28, P=0.012). Conclusions Dietary PUFA intake in patients with acute ischemic stroke or TIA may affect blood metabolism index and oxidative stress index. It is necessary to adjust the dietary structure of patients with low PUFA intake to reduce the risk of stroke recurrence.
