Abstract Background Mucinous adenocarcinoma (MAC) is conventionally diagnosed by WHO definition when the extracellular mucin is more than 50% of the tumour area. The study is aimed at analyzing the clinicopathological characteristics, mutation spectrum, and prognosis of the colorectal adenocarcinoma (CRC) with any mucinous proportion or feature. Methods Clinical and pathological information for 50 patients were reviewed and recorded. Mutation analyses for exon 2–4 of KRAS gene and exon 15 of BRAF gene were performed by Sanger sequencing. Expression of DNA mismatch repairs (MMRs) and P53 proteins was evaluated by immunohistochemistry (IHC). Density of tumour infiltrating lymphocyte (TIL) status was scored. We also evaluated the percentage of glands producing mucin and the morphology of the different tumor cells types in mucin pools. We retrospectively analyzed prognosis of 43 patients with Stage II-III MAC. The primary outcome was progression-free survival (PFS). Results The overall frequencies of KRAS and BRAF mutations were 37.9% and 4.4%, respectively. Patients with MAC exhibiting high levels of mucin were related to the increase of tumor diameter (P = 0.038), but were not associated with any of the other clinicopathological parameters. The proportion or variable morphology of mucinous component did not stratify PFS in Stage II-III tumours. It is interesting to note that male patients had lower TIL compared with female patients (P = 0.018). TIL-low tumors were also correlated with advanced stage (P = 0.041). TIL status was a strong independent predictor of PFS in stage II-III mucinous component tumours (p < 0.001). All four IV stage patients were also classified into TIL-low case. No parameters were independently associated with outcome after adjusting for tumour stage in multivariate analysis. Conclusions TIL status could more accurately determine the biology of the MAC feature for appropriate management, irrespective of quantity or morphology of mucinous component.

Objective.To describe the onset, clinical features, prognostic factors, and treatment of adult-onset Still’s disease (AOSD) in cases from China.Methods.Sixty-one Chinese patients with AOSD were analyzed retrospectively.Results.Common clinical features were fever (100.0%), rash (88.5%), and arthritis (82.0%). The laboratory findings were as follows: leukocytosis (83.6%), increased erythrocyte sedimentation rate (100.0%), elevated transaminase concentrations (23.0%), elevated ferritin levels (79.6%), negative antinuclear antibody (88.5%), and negative rheumatoid factor (88.5%). Of the 61 patients, 44.3% exhibited a monocyclic disease pattern, 29.5% experienced disease relapse at least once, 16.4% exhibited chronic articular course, and 9.8% died; most deaths were due to pulmonary infection and respiratory failure. Based on the disease course, we divided the 61 patients into 2 groups: those with favorable outcome (cyclic disease course, n = 45) and unfavorable outcome (chronic disease course or death, n = 16). We analyzed the prognostic factors for the 2 groups, and found that pleuritis, interstitial pneumonia, elevated ferritin levels, and failure of fever to subside after 3 days of prednisolone at 1 mg/kg/day were unfavorable prognostic factors for patients with AOSD.Conclusion.Patients with AOSD had complex symptoms with no specific laboratory findings. Our results indicate that AOSD is not a relatively benign disease, especially in cases that are refractory to high doses of prednisone.

Significant Difference

Primary aldosteronism (PA) is one of the most common forms of secondary hypertension. Recent studies suggest that, compared with essential hypertension (EH), PA presents more severe disorders of glycolipid metabolism and organ damages. This case-control retrospective study aimed to ascertain clinical features and metabolic parameters between Chinese patients of PA and EH. 174 PA patients and 174 matched EH patients were recruited. Their clinical features, biochemistry parameters, the ventricular septal thickness, and left ventricular mass index (LVMI) were compared. HOMA-β% and HOMA-IR were calculated to evaluate glucose metabolism. The results showed that there was no significant difference regarding BMI, waist-to-hip ratio, and blood pressure between the two groups. The blood potassium level was significantly lower in PA patients than those in EH patients. The abnormal glucose tolerance and the incidence of diabetes in the PA group were not significantly different from those in EH group, but the insulin secretion levels at 0 min and 30 min were significantly weaker than those in the EH group, and the HOMA-β% was also lower in the PA group than those in the EH group. Left ventricular structural abnormalities in PA patients were more severe than those in EH patients. Subtype analysis indicated that patient with aldosterone-producing adenoma (APA) has more serious hypokalemia and lower levels of HOMA-β% and HOMA-IR comparing to those in the idiopathic adrenal hyperplasia (IHA) patient. These findings demonstrated that PA patients showed more impaired insulin secretion function and more severe left ventricular structural damage compared with EH patients.

Objective. This study aimed to clarify the clinical features, the serum level of autoantibodies, and cytokine of myositis patients with anti-EJ antibody, which targets glycyl tRNA-synthetase (GlyRS). Methods. Sera of 236 Chinese patients with myositis were screened for anti-EJ by a novel immunoprecipitation assay of flag-tagged GlyRS. Anti-EJ positive patients are evaluated for the clinical features and cytokine profile. Results. The sera from 4 of 236 adult myositis patients were found to carry the anti-EJ using established novel immunoprecipitation assay and immunoblotting. The prevalence of anti-EJ in our cohorts is about 1.7%. The decline of anti-EJ level was detected in two patients during disease remission. Interstitial lung disease and muscle weakness, but not skin involvement, are common clinical features of anti-EJ positive patients. Moreover, using a cytokine profile analyses, we found that the serum levels of IP-10, IL-6, MCP-1, and VEGF were significantly elevated in patients with anti-EJ and gradually decreased during disease remission of two patients, whereas IL-8 level was obviously reduced in these patients. Conclusion. The novel immunoprecipitation assay is suitable to detect and monitor the levels of anti-EJ autoantibody. The serum levels of anti-EJ, IP-10, IL-6, MCP-1, and VEGF may be related to disease activity in myositis patients with anti-EJ antibodies.
