Objective To determine the optimal volume proportion of iodize d oil (Lipiodol)-ethanol mixture by comparing the clinical efficacy of transhepatic arterial embolization-ablation therapy using different volume proportion of Lipiodol-ethanol mixture in treating experimental rabbit models with VX 2 liver cancer. Methods VX2 tumor was implanted in eighteen adult male New Zealand white rabbits. The 18 VX 2 rabbit models were randomly and equally divided into the following six groups according to the Lipiodol-ethanol volume ratio ∶ group A (3 ∶ 1), group B (2 ∶ 1), group C (1 ∶ 1), group D (1 ∶ 2), group E (1 ∶ 3) and group F (1 ∶ 4). One week after the treatment, all the rabbits were sacrificed and their livers were removed and sent for pathologic examination. The tumor growth rate, the microvascular density, the apoptosis index (AI) of tumor tissues and the injury of the hepatic tissue adjacent to the tumor were evaluated. Results After the treatment, the tumor’s size was increased in group A, E and F. The tumor growth rate of group A was significantly higher than that of the other five groups , and the difference was statistically significant (P<0.05). The tumor’s size of groups B, C and D was decreased, although the difference was not significant when compared with the tumor’s size of groups E and F (P > 0.05). The proportion of ethanol in Lipiodol ∶ethanol mixture bore a negative relationship to the microvascular density counts (R2= 0.840, F = 89.432, P < 0.001). AI of group A was strikingly lower than that of groups C, D, E and F (P < 0.05). The difference in AI between group A and group B was not significant (P > 0.05), while the difference in AI between group B and group C or between group B and group F was statistically significant (P<0.05), and no significant difference in AI existed between each other among other groups (P > 0.05). The injury extent of the hepatic tissue adjacent to the tumor in group A and B was remarkably milder than that of other groups (P < 0.05). Conclusion When considered in terms of safety, the optimal volume proportion of Lipiodol-ethanol mixture should be 2 ∶ 1. Successful super-selective catheterization of the tumor feeding artery, strict and close fluoroscopic monitoring of the injection and proper increase in the proportion of ethanol can definitely improve the therapeutic efficacy.

Methods A total of 80 elderly patients with rheumatoid arthritis were enrolled in the first Affiliated Hospital of Kunming Medical University from December 2014 to October 2016. The quality of life SF-36 score was used to measure the physical health, mental health, daily activities and social health to assess the overall health status of patients. The factors influencing the comprehensive health function of the patients were analyzed by univariate analysis and multivariate linear regression analysis. Results The univariate and multivariate analysis showed that the low level of education, general occupation, marital misfortune, poor economic condition and self-treatment expense were the risk factors affecting the comprehensive health function in elderly patients with rheumatoid arthritis ( P<0.05). Conclusion Elderly patients with rheumatoid arthritis have problems of the functions of daily life, physical health, mental health and social health. To alleviate the high medical costs, improve the level of medical treatment, improve the people 's health and education level and maintain a good mood are the key to improve the overall health in patients with rheumatoid arthritis.

Through morphological observation, HE staining, TRAP staining and toluidine blue staining of bone resorption pits to identify osteoclasts which obtained by 1α, 25-(OH)2 VitD3 inducing rabbit bone marrow cells. Three indicators-TRAP staining, TRAP enzyme activity detecting and the number and area of bone resorption pits were adapted to detect the effect of Sargentodoxae caulis on the activity of osteoclasts. Culturing MC3T3-E1 Subclong 14 cells and detecting the effect of S. caulis on differentiation and proliferation of them by MTT and detecting the alkaline phosphatase in cells. The results show that all of the low, middle and high doses of water and alcohol extracts of S. caulis have significant inhibition on osteoclast differentiation and bone resorption ability in a dose-dependent manner. The low and middle doses of water and alcohol extracts of S. caulis can stimulate differentiation and proliferation of MC3T3-ElSubclone 14 cells, which indicates S. caulis can prevent osteoporosis and the function could be achieved by inhibiting osteoclast activity and promoting the proliferation and differentiation of osteoblasts.

Objective To investigate the expression of serum soluble cytotoxic T lymphocyte associated antigen 4 (sCTLA4), the association of sCTLA4 level with erythrocyte sedimentation rate (ESR) and C reactive protein (CRP), as well as its role in patients with Crohn's disease (CD). The relationship-1661A/G and -1722T/C polymorphisms of CTLA4 gene and between disease susceptibility and phenotype of CD was analyzed. Methods A total of 126 CD patients and 300 healthy controls were enrolled in the study. Serum sCTLA4 level was determined by enzyme-linked immunosorbent assay. The concentrations of ESR and CRP were analyzed by automatic ESR Analyzer SRS 100/Ⅱ and rate nephelometry, respectively. The polymorphisms of CTLA4-1661A/G and -1722 T/C were genotyped by DNA sequencing. Results Serum sCTLA4 level was higher in CD patients than in healthy controls [(18. 70±3. 72) ng/ml vs (1.72±0. 32) ng/ml, P＜0. 01)]. Among CD patients, sCTLA4 level was higher in patients with active disease when compared to those with inactive disease [(19.83±4.35) ng/ml vs (18. 02±3.14) ng/ml, P=0. 015)]. sCTLA4 level was positively correlated with ESR and CRP levels (r=0. 267, P=0. 003; r=0. 524 P ＜0.01, respectively). In CD patients, serum sCTLA4 level was significantly higher in those with stricturing disease behavior than that in those without stricturing and penetrating or with penetrating disease behavior (P= 0.021; P=0. 015, respectively). Detection of CTLA4 -1661A/G and -1722T/C polymorphisms showed no significant difference between CD patients and healthy controls. Conclusions The high level of serum sCTLA4 in CD patients is correlated with disease activity, CRP levels and disease behavior. It suggests that sCTLA4 may play an important role in pathogenesis of CD.
