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 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 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.

A set of central composite design experiments were designed by using four factors which were ethanol amount, ethanol concentration, refrigeration temperature and refrigeration time. The relation between these factors with the target variables of the retention rate of schizandrol A, the soluble solids content, the removal rate of fructose and the removal rate of glucose were analyzed with Bayesian networks, and ethanol amount and ethanol concentration were found as the critical process parameters. Then a network model was built with 2 inputs and 4 outputs using back propagation artificial neural networks which was optimized by genetic algorithms. The R2 and MSE from the training set were 0.983 8 and 0.001 1. The R2 and MSE from the test set were 0.975 9 and 0.001 8. The results showed that network analysis method could be used for modeling of Schisandrae Chinensis Fructus ethanol precipitation process and identify critical operating parameters.

The efficacy of ~(131)I treatment of hyperthyroidism in children and adolescents was evaluated. Being unsuitable for medical therapy,31 patients (aged 11-18 years) with hyperthyroidism received ~(131)I treatment with a dose of 0.925-3.33 MBq/g of thyroid and were followed-up for 20 to 76 months.Fifteen patients were euthyroid,5 suffered from late-onset hypothyroidism,and 11 were still hyperthyroid,but their symptoms and signs of hyperthyroidism were markedly improved.Of the 18 patients with thyroid-associated ophthalmopathy (TAO),8 patients recovered,4 were improved,TAO in 1 patients deteriorated and in S patients remained unchanged.~(131)I is a relative safe and effective treatment for children and adolescents above 10 years old with hyperthyroidism,being unsuitable for medical therapy.
