Objective To observe the influence of early postoperative feeding in the healing of intestinal anastomosis in rabbits,and to clarify preliminarily the relationships between early postoperative feeding after gastrointestinal surgery and gastrointestinal anastomotic fistula formation and healing time in rabbits.Methods 48 rabbits were randomly divided into experimental group and control group, then they were treated with gastrointestinal anastomosis.The rabbits in experimental group were fed with liquid diet 24 h after operation,and the rabbits in control group were fed nothing after operation and supplied by total parenteral nutrition.Two rabbits of each group were selected for exploratory laparotomy on the 3rd,5th,7th,10th and 15th day after operation,and the healing rate of anastomosis,the anastomotic bursting pressure,the anastomotic breaking strength,and the hychoxyproline level of anastomosis were observed.Results The healing rate of anastomosis in control group was 91.6%(22/24), and the healing rate of anastomosis in experimental group was 95.8%(23/24),there was no significant difference between two groups(P>0.05).The anastomotic bursting pressures of the rabbits in two groups were decreased remarkably at the 72nd hour after operation,which was the lowest point,and they were increased remarkably on the 5th day after operation,but the anastomic bursting pressure in experimental group was a little lower than that in control group,and it reached the peak on the 7th day after operation in control group. On the 10th day after operation,the anastomic bursting pressure in control group was a little lower than that on the 7th day after operation,but the anastomic bursting pressure in experimental group reached the peak.There were no significant differences of anastomic bursting pressure at different time points between two groups(P>0.05).The anastomotic breaking strength had no significant difference between two groups at the 72nd hour after operation,both of them reached the lowest points,however the anastomtic breaking strengths in two groups were increased remarkably on the 10th day after operation,and reached the peaks.but there were no significant differences of anastomic breaking strength at different time points between two groups (P>0.05 ). The hychoxyproline level of anastomosis:in experimental group was a little lower than that in control group at the 72tnd hour after operation,and both of them reached the peaks on the 7th day after operation;but there were no significant differences of hychoxyproline levels of anastomosis at different time points between two groups(P>0.05).Conclusion Early postoperative feeding can not cause the increase of anasmotic healing time and the incidence rate of gastrointestinal anastomotic fistula.

Objective To evaluate the quality of Hedysari Radix from different producing areas in Gansu Province by setting Hedysari Radix from different producing areas in Gansu Province as study subjects and trace elements in Hedysari Radix as evaluation indexes; To provide the references for establishment of the quality standards of Hedysari Radix.Methods The content of Fe, Cu, Ca, Mn, Zn, Mg, Cr, Co, Na, Li, Ni and K in Hedysari Radix were detected by using flame atomic absorbption method. Data were analyzed by the factor analysis conducted by SPSS21.0 software. The common factors were extracted by principal component and analytic function for quality comprehensive ranking was established.ResultsThree common factors were extracted, namely F1, F2, and F3. The quality function was Y=0.657F1+0.119F2+0.089F3. Cr, Li, Co, Cu, Zn, Fe and Mg were the characteristic trace elements of Hedysari Radix that could affect the quality of Hedysari Radix. When the quality of Hedysari Radix was evaluated by the contents of trace elements, the quality of wild Hedysari Radix were better than cultivated Hedysari Radix and the quality rank was consistent with the idea that Longnan is the main producing area of Hedysari Radix. The quality of samples from Dingxi area was better.Conclusion The quality evaluation of Hedysari Radix based on trace elements shows the differences in Hedysari Radix from different producing areas in Gansu Province and the results are relatively reasonable.

Objective:To investigate the expression and biological significance of MicroRNA-204 in nasopharyngeal carcinoma (NPC). Methods: qRT-PCR was applied to detect the relative expression of miR-204 in 43 paired nasopharyngeal carcinoma in comparison to the normal nasal mucosa tissues. Pearson chi-square test was used to analyze the relationship between the miR-204 expression and clinical features. The expressions of Bcl-2 and SIRT1 were measured by immunohistochemistry ( IHC ) , Spearman correlation analysis was used to analyze the relationship between miR-204 and Bcl-2,as well as SIRT1. We then transfected the miR-204 mimics into CNE-2 cells,then the Western blot was used to detect the expression of Bcl-2 and SIRT1,which were considered as the potential targets of miR-204. Results:The relative expressions of miR-204 was significantly downregulated in NPC tissues compared to those of the matched normal tumor-adjacent tissues(P<0. 05). Low expression of miR-204 was significantly associated with lymphatic metastasis(P<0. 05) and advanced TNM stage(Ⅲ+Ⅳ,P<0. 05). The expressions of Bcl-2 and Sirt1 in lower miR-204 level group were both higher than in higher miR-204 level group ( P<0. 05 ) . Both the mRNA and protin expression in CNE-2 cells were down-regulated after transfection. Conclusion: Low expression of miR-204 is related to the malignant clinicopathological features in NPC tissues,and miR-204 may through down-regulate Bcl-2 and SIRT1 to suppress NPC genesis and development.

Aim To investigate the effects of indole-selenium on mice's immunological liver injury.Methods The model of immunological liver injury in mice was prepared. The activities of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were assayed by spectrophotometry; the levels of nitric oxide(NO) in serum were assayed by Griess method; tumour necrosis factor-? (TNF-?) activity was determined by ridio immunoassay method and the level of interleukin-1(IL-1) was assayed by MTT dye reduction. Results Indole-selenium (5, 10, 20 mg?kg~(-1)) significantly decreased serum transaminase (ALT, AST) levels,attenuated the area and extent of necrosis and reduced the infiltration of inflammatory cells. Furthermore, indole-selenium significantly lowered the increased TNF-? and NO levels in serum and inhibited the production of TNF-? and IL-1 by peritoneal macrophages. Conclusion Indole-selenium possesses amelioration effect on pathology of immunological liver injury in mice,which was related directly with inhibiting the production of TNF-? and NO levels in serum, decreasing the production of TNF-? and IL-1 by peritoneal macrophages.
