Objective To study the differences of clinical and histopathologic features between ischemic colitis (IC) and ulcerative colitis (UC), which can make for the differential diagnosis and treatments. Methods Comparative analysis were focused on the clinical and histopathologic data of IC patients (20 cases) and UC patients (30 eases). Results The onset duration of IC [(5±7) d] was significantly shorter than that of UC [(953±1354) d]. IC patients tended to have history of cadiovascular diseases or abdominal surgery (65%). The typical clinical manifestations of IC were sudden onset of abdominal pain (85%), hematochezia (60%)and diarrhea (50%), but UC usually presented with abdominal pain (83%), diarrhea (63%), bloody mucopurulent stool (57%) and tenesmus (20%). Colonoscopy showed longitudinal ulceration (60%)on the mesenteric side, the segmental lesions usually involved only 1/4-1/2 of the perimeter of the lumen (80%), and the boundary of lesions was clear (75%) in IC patients. On the contrary, the ulcer of UC was usually map-like (43%), the lesions usually involved the entire lumen (90%), and the pseudopolyp (37%) was another colonoscopic feature of UC. The histopathologic study revealed that dilation and hyperaemia of vessels (90%) were common in IC. Severe edema of mucosa (95%) was usually presented in IC, and the thickened vascular wall (50%) was the histopathologic characteristic of IC.Crypt abscesses (47%) usually appeared in UC. Conclusions The histopathologic characteristics and differences of colonoscopic findings and clinical features provide strong bases for the differentialdiagnosis between IC and UC.

Objective To investigate the autophagy and apoptosis in acute myelogenous leukemia U937 cell induced by Sirolimus.Methods U937 cells were subcultured, and blank control group(normal) and Sirolimus treated groups(12 h, 24 h,48 h) were established.The Sirolimus treated groups were treated by 2 μmol/L concentration of Sirolimus for 12 h,24 h and 48 h, respectively.The cell morphology of U937 cells treated by Sirolimus was observed after 12 h,24 h and 48 h.The survival rate of cells was detected by cell counting kit-8 method.Cell apoptosis was detected by flow cytometry using Annexin V-FITC/PI double labeled.Real-time PCR was used to detect the level of mRNA expression in autophagy specific protein maker mictotubule-associated protein light chain 3 (LC3)-Ⅱ in different treated times by Sirolimus.Sirolimus LC3 protein expression levels after treatment were detected by Western blot method.Results Under inverted microscope, the cell number of Sirolimus treatment group reduced gradually after 12 h ,24 h and 48 h culture, volume of cells became smaller, cells got ruptured, and the nucleus pycnosis and cellular debris increased.With the extension of time, U937 cells survival rate was falling, and there was statistical differences compared with those of the control group(P =0.031).With Sirolimus treatment, U937 cells after 12 h,24 h and 48 h, U937 cell apoptosis rate increased, and there were statistically significances, compared with those of the control group (P =0.027).With Sirolimus treatment U937 cells after 12 h,24 h and 48 h,LC3-Ⅱ mRNA expression and protein expression were down-regulated compared with those of the control group, and there were statistically significances (P =0.029).Conclusions Sirolimus can induce autophagy and apoptosis in U937 cells.Autophagy protein LC3-Ⅱ in gene and protein expression levels were lowered, and LC3-Ⅱ may play an important role in regulating the leukemia cell autophagy.

Objective:To investigate the clinical significance of fluid-attenuated inversion recovery (FLAIR) vascular hyperintensities (FVHs) in patients with chronic atherosclerotic middle cerebral artery occlusion.Methods:From July 2016 to November 2020, patients admitted to the Department of Neurology, Jiangdu People's Hospital of Yangzhou and first found chronic atherosclerotic middle cerebral artery occlusion were enrolled. The demographic, clinical and MRI imaging data were collected. According to the presence or absence of acute cerebral infarction, they were divided into the non-acute cerebral infarction group and the acute cerebral infarction group. According to the modified Rankin Scale score at 3 months after the onset, patients with acute cerebral infarction were further divided into the good outcome group (≤2) and the poor outcome group (>2). A multivariate logistic regression model was used to analyze the independent correlation between FVHs and the risk of cerebral infarction in patients with chronic atherosclerotic middle cerebral artery occlusion and the outcome in patients with cerebral infarction. Results:A total of 94 patients with chronic atherosclerotic middle cerebral artery occlusion were enrolled, including 38 with non-acute cerebral infarction (40.4%) and 56 with acute cerebral infarction (59.6%). In patients with acute cerebral infarction, 13 (23.2%) had a poor outcome, and 43 (76.8%) had a good outcome. The fibrinogen level, the proportion of patients with FVHs and the FVHs score in the cerebral infarction group were significantly higher than those in the non-cerebral infarction group (all P<0.05). Multivariate logistic regression analysis showed that the FVHs score was significantly, independently, and positively correlated with the risk of acute cerebral infarction (odds ratio 2.524, 95% confidence interval 1.400-4.552; P=0.002). The National Institutes of Health Stroke Scale score at admission, the modified Rankin Scale score at admission, and FVHs score in the poor outcome group were significantly higher than those in the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that there was a significant independent negative correlation between the FVHs score and the outcome of patients with cerebral infarction (odds ratio 0.144, 95% confidence interval 0.045-0.459; P=0.001). Conclusions:FVHs suggest that the blood supply is in a state of decompensation. When FVHs are present, the risk of cerebral infarction in patients with chronic middle cerebral artery occlusion is significantly increased; the wider the range of FVHs, the higher the risk of poor outcome after cerebral infarction.
