Objective To investigate the incidence of postoperative hepatic metastasis,clinicolpathological characteristics and the prognosis for pancreatic cancer. Methods Totally 83 cases with pancreatic cancer admitted in our hospital during January 2007 to September 2012 was retro?spectively analyzed according to clinicolpathological data. Results Postoperative liver metastasis occurred in 31 cases with a metastatic rate of 37.3%. The size(χ2=9.606;P=0.002),vascular invasion(χ2=4.794,P=0.029)and UICC stage(χ2=5.318,P=0.021)were correlated with he?patic metastasis. Univariate analysis revealed the poor prognosis in pancreatic cancer patient with hepatic metastasis(χ2=9.967,P=0.002). Cox re?gression analysis revealed hepatic metastasis as an independent prognostic factor(P=0.001). Conclusion Pancreatic cancer has a high possibility of hepatic metastasis. Postoperative hepatic metastasis was one of the independent factors for the prognosis of pancreatic cancer. Tumor size,vascular invasion and UICC stages were risk factors for postoperative liver metastasis of pancreatic cancer.

Objective To compare the short-term clinical outcomes of hand-assisted laparoscopic surgery(HALS),laparoscopic-assisted surgery (LAS)and open surgery(OS)for colorectal cancer treatment. Methods The clinical data of 74 patients underwent HALS,LAS and OS for colorectal cancer treatment between October 2011 and December 2015 were assessed retrospectively. All the surgeries were performed by the same surgical team. The intraoperative details,postoperative recovery,postoperative complications,oncologic results and cost were compared among the three groups. Results A total of 24 patients in HALS group,25 patients in LAS group and 25 patients in OS group were finally included. The gen-eral data and oncologic baseline were comparable among the three groups. The comparative results showed that the operative time increase d and in-cision length shortened gradually in OS group,HALS group and LAS group(P<0.05). HALS group was favor of less number of trocars used com-pared with LAS group(P<0.05),but there was no statistical difference of the conversion rate between the two groups(P>0.05). In terms of post-operative recovery,postoperative complications and oncologic results,there was no statistical difference between the three groups(P>0.05). As for cost,the total cost and operative cost of OS group were lower than HALS group and LAS group(P<0.05),but there was no significant differ-ence between HALS group and LAS group(P>0.05). The material cost increase gradually in OS group ,HALS group and LAS group(P<0.05), and there was no significant difference on the part of other cost among the three groups(P>0.05). Conclusion HALS,LAS and OS are compen-satory with each other,and clinicians can choose the reasonable procedure according to personal proficiency and situation of patients.

We present an unusual case of an unstable pelvic fracture during pregnancy period, who suffered fetal death and splenic rupture simultaneously which developed massive delayed hemorrhage in abdomen. When considering potential causes of fetal death, direct trauma to the uterus, placenta, or fetus was not associated with a higher fetal mortality rate, compared with maternal hemorrhage. A cesarean section and splenectomy could rescue the maternal life from the hemorrhage situation. Successful treatment of these rare cases is possible with careful pre-, peri-, and post-operative evaluation of the mother and fetus by a multidisciplinary team.

Background Oxidative damage plays an important role in pathogenesis of age-related macular degeneration( AMD ),and its mechanism is the destroy of blood-retinal barrier.Müller cells is a primary component to stabilize the inner barrier of the blood-retina.Researches showed that epidermal growth factor(EGF) can promote the proliferation and migration of animal Müller cells,but less study was found in the effect of EGF on human Müller cells. Objective The present study was to investigate the effects of EGF on the proliferation and migration of human Müller cells and its molecular mechanism. Methods Human Müller cell line MIO-M1 cells were cultured and incubated,and cultured cells were identified using glial fibrillory acidic protein (GFAP),factor Ⅷ,α-smooth muscle actin( α-SMA ),keratin and S-100.Different concentrations of EGF( 0,1,10,30,100 mg/L)was added in freeserum DMEM,and the positive rate of the cells was calculated using 5-bromo-2-deoxyuridine(BrdU) method.The cells were divided into EGF group,H2 O2 group,EGF + H2 O2 group,glucose oxidase ( GO ) group,GO + EGF group,EGF + LY294002+H2O2 group according to the different intervention,and the effects of LY294002 on the proliferation of Müller cells (A590 )were detected by colorimetric assay for cellular growth and survival( MTT assay).The scratch test of Müller cells was used to assess the influence of EGF(0,1,10,30,100 mg/L)on H2 O2-induced damage of human Müller cell.Western blot was used to detect the cell proliferation under the protection of EGF on co-cultured cells using LY294002 and H2O2 and the activation of Akt signal pathways. Results The proliferative rates of the cells were 28.0%,32.9%,39.0% in 10,30,100 mg/L EGF groups respectively and obviously higher than those in 0,1 mg/L EGF groups (24.5 %,26.2 % ).Under the H2O2 culture,GO culture,respectively,the A570 value of the Müller cell in high concentrations of EGF groups was significantly increased in comparison with lower concentrations EGF groups with the statistical significance among the groups( F=23.582,P=0.000).Compared with EGF+H2O2 group,the A570value of the Müller cells was lowed in EGF+LY294002+H2O2 group.The maximum migration rate of Müller cells was found in 10 mg/L EGF group.Western blot revealed that the presence of H2O2 reinforced the expression of Akt in Müller cells,however,pretreatment with 100 mg/L EGF antagonized the harmful effect of H2O2 on Müller cells.Meanwhile,pretreatment with EGF and LY294002 reduced the expression of Akt in Müller cells. Conclusions EGF can induce the proliferation and migration of human Müller cells with the strongest effect in 10 mg/L.100 mg/L exogenous EGF has a stronger protection to the Müiller cells against H2O2-induced cell damage by activating the PI3KAkt cell survival pathway.
