ObjectiveTo observe the effects of high mobility group box-1 protein ( HMGB1 ) on function of murine spleen IL-10-producing dendritic cells (DCs) subset CD11clowCD45RBhighDCs.MethodsSplenic CD11clowCD45RBhighDCs and CD4 +T cells in Balb/c mice were purified by magnetic beads sorting.CD11clowCD45RBhighDCs were treated with various doses of HMGB1 (0,20,100,500ng/ml).Flow cytometry was used to determine expressions of CD11clowCD45RBhighDC surface molecules including CD40,CD80,CD86,Ⅰ-a/e and Toll-like receptor (TLR) 4.IL-10 level in CD11clow CD45RBhighDC culture supernatants was determined by ELISA method.The CD4+ T cells were divided into four groups: control group (without only treatment),untreated group (HMGB1-untreated CD11clow CD45RBhigh DCs plus CD4+T cells),high-dose HMGB1-treated group (500 ng/ml HMGB1-treated CD11clowCD45RBhigh DCs plus CD4 +T cells),high-dose HMGB1-treated + antibody 1 group (500 ng/ml HMGB1-treated CD11clowCD45RBhigh DCs plus IL-10 antibody and CD4+T cells),high-dose HMGB1-treated + antibody 2 group (500 ng/ml HMGB1-treated CD11clow CD45RBhigh DCs plus homotype IL-10 antibody and CD4 +T cells).IL-4 as well as interferon( IFN-γ) contents in CD4 + T cell culture supernatants were determined by flow cytometry.ResultsHMGB1 could markedly enhance the expressions of CD40,CD86 and TLR4 on CD11clowCD45RBhigh DC surface as well as level of IL-10 secreted by CD11clow CD45RBhigh DCs as compared with the non-HMGB1 treatment.Meantime,the secretion of IL-10 was HMGB1 concentration dependent.IFN-γ level in high-dose HMGB1-treated group was (279 ± 17) pg/ml,which was markedly lower than that in the untreated group [ (963 ± 11 ) pg/ml,P ＜ 0.05 \ ].IL-4 level in high-dose HMGB1-treated group was (372 ± 14) pg/ml,which was significantly higher than that in the untreated group [ (213 ± 10) pg/ml,P ＜0.05) \].ConclusionsHMGB1 promotes IL-10 production in CD11clowCD45RBhighDCs,induces the differentiation of CD4 +T cells to Th2 cells and downregulates the immune response via activating CD11clowCD45RBhigh DCs.

Colorectal cancer is one of the most common malignancies in human.Early diagnosis is the key points in improving the prognosis of patients with colorectal cancer.The implementation of standardized operation and comprehensive treatment for advanced and late stage cancer can improve the outcome.Based on the pattern of lymph node metastasis and the concept of complete mesocolic excision,the operation of colonic cancer has entered the era of normalization and standardization.The surgical procedure of rectal cancer (especially low rectal cancer) should be individualized based on the gold standard of total mesorectal excision (TME).For hepatic metastasis of colorectal cancer,hepatectomy is currently the standard and the only potentially curative treatment method.Therefore,how to evaluate the resectability of hepatic metastasis of colorectal cancer is particularly important.Surgeons are the most important participants in the diagnosis and treatment of colorectal cancer,and standardized diagnosis and treatment is the key to improve the prognosis of patients.

Translation is a process not only concerning on the language transformation, but also concerning on the cultural communications. However, due to the diversity between cultures, translation loss is a stumbling block which has to be coped with, or a necessary process called translation compensation. This paper, employing the method of text analysis, attempts to compare two English versions ofHuangdi-Neijing by Veith and Li-Zhaoguo as study cases to discuss the translation compensation strategies from the perspective of Bassnett’s cultural translation theory, thus achieving the optimal translation effect.

Objective To compare the treament to adhesion ileus between laparoscopic surgery and traditional surgery.Methods 59 cases of patients with adhesion ileus were selected.32 patients were given laparoscopic adhesion ileus loose solution method.And the other 32 patients were given traditional surgery.Results The operation time(t =12.135,P =0.002),peristalsis recovery time (t =9.053,P =0.001),postoperative infection rate (x2 =8.346,P =0.004),obstruction again (x2 =4.863,P =0.026) and hospital stays (t =4.724,P =0.028) in laparoscopic surgery group was significantly better.The differences between both groups were statistically significant (P ＜0.05).Conclusion Compared with the traditional open surgery,laparoscopic adhesion ileus loose solution with surgical trauma is small.Operation time and the postoperative recovery time is short,It can be used as the main treatment of adhesion ileus.

Objective To investigate the protective effects of glycine on the lung injury in acute necrotizing pancreatitis(ANP). Methods Male Wistar rats were randomly divided into 4 groups: sham operation, ANP group,pretreated group and treatment group(with intravenous glycine 1g/kg). Serum TNF ? level,glutathione (GSH) and myeloperoxidase (MPO) in pulmonary homogenate were determined at 6, 12, and 24h hours after ANP induced. Pulmonary pathology and 3 day survival rate were compared between the groups.Results Compared with ANP group,in glycine pretreated group serum TNF ? level significantly reduced at 6,12, and 24h,while in glycine treatment group serum TNF ? level decreased at 24-hour . In glycine pretreated group or treatment group, the pulmonary GSH content were decreased.In both glycine pretreated group and glycine treatment group, pulmonary MPO activity decreased at 12 and 24h,and pulmonary pathologic severity significantly ameliorated and survival rate increased. Conclusions Although glycine can not increase the GSH synthesis,but giving prophylactic or therapeutic glycine may be effective in improving acute lung injury in ANP, probably through the inhibition of the infiltration and activation of leukocytes.

Dioxin,as a kind of strong carcinogenic substance,a kind of environment hormone with tremendous harm,can get into human body through food chain and accumulate in fat of animals and persons,forming serious threat to human health. Dioxin has been included in the list of monitoring objects in food part of the global environment monitoring program as a new environmental pollutant by World Health Organization. In this paper,the toxicity,the source of dioxin and its impact on human health and prevention and control measures are introduced.

Janus kinase-signal transduction and transcription activator (JAK-STAT), mitogen- activated protein kinase (MAPK) and nuclear factor ?B (NF-?B) are three important cellular signalling pathways, which play pivotal roles in regulation of cellular physiologic as well as pathophysiologic functions. Based on the elucidation of the research progress of three signalling cascades, respectively, the current review focuses on the cross-talk of these signalling transduction, and the up-to-date details are also presented on their regulation in inflammatory response.

Objective To investigate the clinical manifestations, histopathological patterns and causes of misdiagnosis of primary malignant tumor in small intestine (PMTSI). Methods The clinical data of 90 cases of PMTSI confirmed by pathology admitted from 1981 to 2002 in our hospital were retrospectively analyzed. Results The main pathological patterns of PMTSI were adenocarcinoma, leiomyosarcoma, lymphoma and malignant neurilemmoma. The common clinical manifestations were abdominal pain, anemia and hemorrhage, jaundice, weight loss and intestinal obstructions. Preoperative diagnosis rate was 22.2%(20/90). It was easily misdiagnosed as other digestive tract diseases and pelvic disorders. Preoperative misdiagnosis rate was 77.8%. Conclusions The main pathological patterns of PMTSI are adenocarcinoma, leiomyosarcoma, lymphoma and malignant neurilemmoma.Its clinical manifestations and diagnostic examination methods are not good enough, which usually leads to misdiagnosis ,so attention must be paid.
