OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.

METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.

RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).

CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.

Recent epidemiologic data indicate that metfomin has an anti-tumor effect.However,the underlying anti-tumor mechanisms remain unclear.MicroRNAs (miRNAs)can exhibit pro-oncogenic or anti-oncogenic effects by regulating the differentiation and proliferation of cells.In vitro studies show that metformin can regulate the expressions of multiple miRNAs which are closely associated with tumor development,a process possibly relating to the anti-cancer roles of metformin.

Objective To investigate the safety, feasibility and results of laparoscopic assisted distal radical gastrectomy for gastric cancer. Methods Twenty-three cases of gastric cancer were subjected to laparoscopic assisted distal radical gastrectomy, D_(1+α)/D_(1+β) lymphadenectomy on 3 cases and D_2 lymphadenectomy on 20 cases. All cases received Billroth I reconstruction. Results Laparoscopic assisted distal radical gastrectomy was carried out in all cases successfully. The mean operative time was (205 ±38 )min, mean blood loss was (105 ± 66) ml and mean number of lymph nodes dissected was 19.7 ± 6.2 each case. The mean postoperative time of recovery of bowel function was (3.5 ±1.2) d,mean postoperative time of liquid intake was (4.9 ±0.9) d and mean hospitalization was (10.2 ± 2.7) d. No postoperative death or anastomotic fistula was found. Postoperative upper gastrointestinal bleeding occurred in 1 case and was cured by conservative treatment. Follow-up for 1-12 months revealed no recurrence or metastasis. Conclusions Laparoscopic assisted distal radical gastrectomy is a safe and feasible procedure with satisfactory short-term outcomes.Moreover,the short-term outcomes may be improved if the patients are treated under the notion of fast track surgery.

OBJECTIVETo investigate the diagnostic significance of D2-40 and annexin-1 in the ependymal tumors.

METHODSTo analyses the expression of D2-40, annexin-1, EMA and Ki-67 by immunohistochemistry in 52 cases of ependymal tumors (48 cases of ependymomas, 4 cases of choroid plexus papilloma) from Xuanwu Hospital from 2005 to 2009. Ten cases of corresponding normal brain tissue were also obtained as control.

RESULTSThirty-two of forty-eight (66.7%) cases of ependymomas were positive for D2-40. "Dot-like" and "ring-like" structures were commonly observed in ependymomas (55.3%, 21 of 38 cases) and anaplastic ependymomas (5 of 6 cases) with D2-40 staining. There was no difference in the expression between D2-40 and Ki-67 (r(s) = -0.013, P = 0.931). For annexin-1, 87.5% (42 of 48 cases) of the ependymomas were positive. The specific "granular structures" and cilium were observed in ependymomas (1 of 4 cases of myxopapillary ependymomas and 11 of 38 cases of ependymomas respectively) for annexin-1. The difference in expression between annexin-1 and Ki-67 was statistically significant (r(s) = -0.405, P = 0.005). D2-40 in combination of EMA and annexin-1 increased the positive rate to 100% in ependymomas. Choroid plexus papillomas were all positive for D2-40 and annexin-1. The control tissue was negative for D2-40 but positive for annexin-1 in the capillaries.

CONCLUSIONSThe specific structures are valuable in diagnosing of ependymal-genetic tumors, and are highlighted by D2-40 and annexin-1. D2-40 in combination of EMA and annexin-1 is a useful diagnostic marker for ependymal tumors.

Background and purpose:The chemokine,CXCL12 and its receptor,CXCR4,have recently been shown to play an important role in the metastasis of several kinds of carcinoma. It also has been demonstrated that VEGF regulates both the expression of CXCR4 and invasiveness in cancer cell. Our aim was to study the expression of CXCR4,VEGF in osteosarcoma and the correlation between these two factors and distant metastasis. Methods: The immunohistochemical staining SP method was used to detect the expression of CXCR4 and VEGF in 56 cases of osteosarcoma. We analyzed the correlation between the expression of CXCR4 and VEGF,and the correlation between the expression of CXCR4,VEGF and clinical stage,the level of ALP. The patients were followed up for 2 years. Results:There was signifi cant correlation between the expression of CXCR4 and VEGF in 56 cases(r=5.678,P=0.02). Univariate analysis showed a signifi cant correlation between the expression of CXCR4,VEGF and clinical tumor stage(P=0.026),and no correlation between the expression of these two factors and age,sex and serum ALP level. 31 cases had metastasis in two years in a total of 56 follow-up cases,and the expression of CXCR4 and VEGF was associate with metastasis(P=0.018 and P=0.022,respectively). Conclusion:VEGF can upregulate tumor angiogenesis and promote tumor metastasis to specific organ by increasing expression of CXCR4.The increasing expression of CXCR4 and VEGF is useful to predict metastasis and prognosis of osteosarcoma.
