Objective To examine the clinical factors associated with postoperative outcome in dementia combined with cerebral amyloid angiopathy-related intracerebral hemorrhage (CAA-ICH). Methods The clinical data of 25 surgical patients of dementia combined with CAA-ICH were retrospectively analyzed. The postoperative short-term effects and long-term effects were evaluated at the 30 d and 6 months after operation according to the modified Rankin score (MRS), and the influencing factors were analyzed. Results Among the 25 patients, eusemia was in 6 cases. Age ≥ 75 years, Glasgow coma score (GCS) ≤ 8 scores on admission, hypertension, postoperative anemia, pulmonary diseases, midline shift were the influencing factors of postoperative short-term effects (P < 0.05 or <0.01). Twenty-two patients were followed up for 6 months, and ensemia was in 9 cases. Age≥75 years, GCS ≤ 8 scores on admission, hypertension, postoperative anemia, hypoproteinemia and pulmonary diseases were the influencing factors of postoperative long-term effects (P<0.01 or<0.05). Conclusions Preoperative assessment is important for the patients of dementia combined with CAA-ICH. Age ≥ 75 years, GCS ≤ 8 socres on admission, hypertension, postoperative anemia, pulmonary diseases, midline shift are associated with poor short-term effects; age ≥ 75 years, GCS ≤ 8 scores on admission,hypertension, postoperative anemia, hypoproteinemia and pulmonary diseases are associated with poor long-term effects.

Objective To investigate the differences in the biochemical and pathological features and therapeutic response between the elderly-onset autoimmune hepatitis (AIH) and young-onset AIH.Methods From October 2013 to November 2016,a total of 87 consecutive AIH patients diagnosed by liver biopsy were enrolled and divided into elderly-onset group (≥60 years) and the young-onset group (＜ 60 years).The biochemical and pathological features and therapeutic response of the two groups were compared.Mann Whitney test and chi square test were performed for statistical analysis.Results As AIH diagnosed,the proportion of liver cirrhosis detected by imaging examination of elderly-onset group and the young-onset group were 67.7％(21/31) and 35.7％(20/56),respectively,the former was higher than the latter,and the difference was statistically significant (X2 =8.214,P=0.004).The proportion of patients complicated with extrahepatic autoimmune diseases of the elderly-onset group was 9.7％ (3/31),which was lower than that of the young-onset group (28.6％,16/56),and the difference was statistically significant (X2 =4.173,P=0.041).The median levels of alanine aminotransferase (ALT) and albumin of the elderly-onset group were 50.0 U/L (22.0 U/L,193.0 U/L) and 34.8 g/L (31.3 g/L,40.5 g/L),which were lower than those of the young-onset group (146.0 U/L (43.8 U/L,390.5 U/L),39.4 g/L (35.8 g/L,44.6 g/L),and the differences were statistically significant (Z=-2.109,-2.092;both P＜ 0.05).Between the two groups,there was no statistically significant difference in inflammation grade,fibrosis stage,interface hepatitis,lymphoplasmacytic infiltration,positive rate of hepatocyte rosette pattern,positive rate of centrilobular necrosis and small bile duct injury (all P＞0.05).After treatment,among 17 patients of elderly-onset group,seven patients obtained biochemical remission and the median time to remission was 3.2 months;among 37 patients of young-onset group,18 patients (48.6％) obtained biochemical remission and the median time to remission was 2.3 months.There was no significant difference in the percentage of patients achieved biochemical remission and the median time between the two groups (both P＞0.05).Conclusion The percentage of complicated with extrahepatic autoimmune diseases of elderly-onset group is lower than that of young-onset group,which indicates that age-associated immune dysfunction may involve in the genesis and development of elderly-onset AIH.

Objective:To study the action of Xinnaotong on adhesion molecule expression by cultured endothelial cells and platelets. Methods: Tumor necrosis factor ?(TNF ?) stimulated ICAM I expression on the cell surface was studied with human umbilical vein endothelial cells(HUVEC).Thrombin stimulated expression of platelet P selectin was studied with human blood platelets. Adhesion molecule expression was measured by flow cytometry. Results: ICAM I molecule expression on HUVEC was significantly stimulated by TNF ?. The stimulatory effect of TNF ? on HUVEC was inhibited by Xinnaotong(0.25～2g/L) in a concentration dependent manner. The same dose of Xinnaotong can inhibit the p selectin expression on human blood platelets stimulated by thrombin. Conclusion: Xinnaotong inhibites expression of adhesion molecues(ICAM I, p selectin) in HUVEC and in human blood platelets.

Objective To assess differences in brain activation between active and passive movement of the right hand using blood oxygen level-dependent functional magnetic resonance imaging (BOLD-fMRI). Methods Nine healthy adult right handed volunteers were studied. fMRI was performed with active and passive finger-to-finger movement. Results Right hand active and passive movement produced significant activation in the contralateral sensorimotor cortex ( SMC ), the contralateral premotor cortex ( PMC ), bilaterally in the supplementary motor area (SMA) and in the ipsilateral cerebellum. The activated brain areas were centered on the contralateral SMC and PMC and located more forward during active movement than during passive movement. The contralateral SMC was the most strongly and the most frequently activated brain area. The contralateral posterior parietal cortex (PPC) was less relevant to the hand movements. Unlike active movement, passivemovement activated more areas in the posterior central gyrus than in the anterior central gyrus. Conclusions Both active and passive movement significantly activate the brain areas which are responsible for hand movement, but there are some differences in the locations of the cortex areas activated and in the incidence activation except in the contralateral SMC.

Objective To evaluate the value of dynamic susceptibility contrast-enhanced MR imaging (DSC)in evaluation of brain tumor after operation.Methods 41 cases with brain tumors verified histologically,including 8 cases of high-grade gliomas,16 of low-grade gliomas,7 of metastases and 10 of meningiomas underwent DSC examination.All the cases at 3.0T MR unit.All primitive data were sent to ADW4.3 workstation for post-processing.The mean maximal rCBV and rCBF ratios of tumors,1 cm and 2 cm regions of peri-tumor were obtained respectively.The relativity of MR perfusion parameters(rCBV and rCBF)between diferent tumors were statistically evaluated by using Pearson correlative analysis.Results In the　solid region of tumors,rCBV and rCBF were statistically significant differences (P<0.05)between low-grade gliomas and the other three groups of tumors; in 1 cm region of peri-tumor between high-grade gliomas and the other three groups,and between low-grade gliomas and metastases,between the solid region and both regions of 1 cm and 2 cm peri-tumors at the same tumor were all of statistically significant differences(P<0.05),between 1 cm and 2 cm region of peri-tumors at high-grade gliomas and metastases,the rCBV and rCBF were also of statistically significant differences.Pearson correlative analysis showed that there were significant positive correlations between the mean maximal rCBV and rCBF　ratios at the same region in the same tumor's group.Conclusion DSC is very valuable in evaluation of the histopathological grade and the differentiation of brain tumor.

Objective To compare the difference between GUSS swallowing evaluation and traditional evaluation as a symbol of pulling out stomach tube.Methods 60 patients with cerebral hemorrhage combined with indwelling tube were divided into two groups,the GUSS group and the traditional group,according to the symbol of pulling out the gastric tube.Each group contained 30 cases.The GUSS score ≥ 15 points was used as the symbol of pulling out the gastric tube in the GUSS group,while being able to eat 200 ml liquid without any trouble in two days was used as the symbol in the traditional group.Then we compared the incidence of gastric tube reinsertion and aspiration pneumonitis between the two groups.Results No gastric tube reinsertion and aspiration pneumonitis occurred in the GUSS group,while 7 cases accepted gastric tube reinsertion and 3 cases diagnosed as aspiration pneumonitis in the traditional group.The incidence of gastric tube reinsertion and aspiration pneumonitis in the GUSS group were obviously lower than those in the traditional group.Conclusions GUSS evaluation score ≥ 15 points could be used as a symbol of pulling out gastric tube.
