Objective To study the relationship between the type of histopathology and prognosis of contained mucous adenocarcinoma(CMAC) of stomach and its clinical significance. Methods Eighty-seven cases of CMAC of stomach were observed by means of pathomorphology, histochemistry, immunohistochemistry and follow up etc. Results The malignant behavior of the cancer was significant difference according to the nature and quantity of the CAMC and the primary pathological type of the cancer.The clinical type in simple mucous carcinoma was mainly Borrmann type I;in tubular papilla mucous adenocarcinoma was mainly Borrmman type II; in signet-ring cell mucous carcinoma was mainly Borrmman type IV,and in mixed cell mucous carcinoma was mainly Borrmman type III. There was significant difference in the lymphatic metastasis and survival rate between the 4 groups. Conclusions Correct differentiation of the pathological type of contained mucous adenocarcinoma of stomach is important for guading the treatment and predicting the prognosis.Cathepsin D expression can help for understanding the biological behavior of CMAC of the stomach.

Objective To investigate the clinical, neuroimaging and serum risk factors of cerebral microbleeds (CMBs) in patients with ischemic stroke and find the associations between these risk factors and the location and num?bers of CMBs were also analyzed. Methods One hundred and fifty-three patients with acute ischemic stroke were re?cruited in this study and their data werewas retrospectively analyzed. All of the patients underwent MRI- susceptibility weighted imaging (SWI). The location and numbers of CMBs were recordedexamined. The severity of WMLs was assessed using the Fazekas scale. Logistic regressions were performed to find the predictors of the presence of CMBs. The relation?ships between these risk factors and the location and numbers of CMBs were also analyzed. Results Fifty-nine(38.6%) cases had at least one CMB. The frequency of cortical-subcortical, deep and infratentorial CMBs were 34.0%, 24.8%and 27.5%, respectively. Multivariate logistic regression showed that male sex, hypertension and moderate-to-severe deep white matter hyperintensities (DWMH) were independent risk factors of the presence of CMBs. Adjusted with age and sex, partial correlation showed that hypertension only correlated with the numbers of deep CMBs significantly (r=0.174, P=0.032). Moderate-to-severe DWMH significantly correlated with the numbers of cortical-subcortical and deep CMBs (r=0.285, P<0.001 and r=0.258, P=0.001, respectively). Conclusion Male sex, hypertension and moderate-to-severe DWMH were are independent risk factors of CMBs in patients with ischemic stroke. Hypertension correlates with Deep deep CMBs, while Moderatemoderate-to-severe DWMH correlates with cortical-subcortical and deep CMBs.

Objective To investigate the clinical manifestation,neuroimaging characteristics and follow-up results of chorea associated with non-ketotic hyperglycemia (C-H-BG).Methods Clinical data of six patients with C-H-BG were analyzed retrospectively.Results The average age of the six patients (five female and one male) was 65.8±13.9 years,All patients had acute-subacute course.Patients presented with choreic movements involving facial muscles (n=6) and unilateral (n=5) or bilateral limbs (n=1).The average value of plasma glucose at admission was 9.21 ± 5.15 mmol/L.All patients had significantly elevated HbA1c (14.1 ±3.5％).The brain MRI T1 imaging from all patients showed hyperintensity in the basal ganglia,putamen,lenticular nucleus and caudate nucleus.SWI imaging revealed corresponding hypointensity signal in the basal ganglia in three patients.Two patients had severe stenosis of the MCA.Five patients were followed up for an average of 16.2 ±7.2 months.Three patients died.Conclusion The high T1 hypertense lesions in the basal ganglia are the mainly radiological feature of C-H-BG which may be accompanied by SWI hytointense signals in the basal ganglia.

Objective To investigate the correlation between total burden of cerebral small vessel disease (CSVD) and cognitive impairment in patients with acute basal ganglia infarction. Methods Patients with acute basal ganglia infarction for the first time were enrolled, and the general data of the enrolled patients were collected. Patients were assessed by Montreal cognitive assessment (MoCA). Based on MoCA assessment, patients were then divided into cognitive impairment (CI) group and non-cognitive impairment (NCI) group. CSVD total load scores were conducted afterwards in order to analyze the correlation between the total load of different degrees of cerebral small vessel disease and cognitive impairment. Results A total of 178 patients were enrolled in this study: 135 in the CI group and 43 in the NCI group. There were significant differences in age (t=4.11, P=0.04) but not in high-density lipoprotein (t=2.92, P=0.09), and glycosylated hemoglobin C (t=3.02, P=0.08) between the two groups. The infarct volume was larger in the CI group (CI group: 424.72±36.55, NCI group: 227.02±34.62, t=4.022, P=0.046). There were significant differences in a sing1e lentiform nucleus (χ2=19.08, P<0.01), caudal Nucleus(χ2=9.97, P<0.01), infarction at the site of internal capsule(χ2=3.85, P=0.05), the infarct site involved lentiform nucleus, internal capsule and caudate nucleus at(χ2=4.30, P=0.04), and numbers of patients with moderate-to-severe internal carotid artery stenosis (χ2=4.14, P=0.04) as well as numbers of patients with moderate-to-severe intracranial artery stenosis (χ2=4.19, P=0.04). Similarly, there were significant differences in CSVD total burden (t=3.62, P<0.01), deep white matter hyperintensity (t=9.02, P<0.01), and cerebral microbleeds (t=5.54, P=0.02) between CI group and NCI group. The comparisons on MoCA score, visuospatial and execution, attention, language, generalization and abstraction, memory and orientation but not naming were statistically significant between the two groups. The logistic regression equation showed that CSVD total burden (OR=0.316, 95%Cl: 0.185~0.541, P<0.001), age (OR=0.924, 95%Cl: 0.884~0.967, P=0.001) and infarct volume (OR=0.924, 95%Cl: 0.884~0.967, P=0.001), (95%Cl: 1.000~1.003, P=0.047) was significantly associated with cognitive impairment in patients with acute basal ganglia infarction. Conclusion High CSVD total load score, older age and larger infarct volume may be risk factors for cognitive impairment in patients with acute basal ganglia infarction.
