Objective To assess the agreement of preoperative ultrasonography (US), CT, intraoperative ultrasonography(IOUS) and intraoperative palpation in the diagnosis of liver tumors. Methods The results of preoperative US,CT, IOUS and intraoperative palpation in the diagnosis of liver tumors in 70 patients were reviewed,and the agreement of them were evaluated. Results There was a moderate level of agreement between US and the pathology and follow-up in the diagnosis of liver tumors (Kappa = 0.63). There was a high level of agreement among CT, IOUS and the pathology and follow-up(CT vs the pathology and follow-up, Kappa = 0.72;IOUS vs pathology and follow-up, Kappa = 0. 89;CT vs IOUS, Kappa =0.53), whereas the level of agreement between intraoperative palpation and the pathology and follow-up (Kappa =0.38), US and intraoperative palpation (Kappa = 0.23), US and IOUS (Kappa = 0.23) was low. Conclusions In the assessment of liver tumors,CT and IOUS have a high agreement. Although the agreement of US and intraoperative palpation were low, they were still indispensable. Four methods were integrated, will contribute to the diagnosis and treatment of liver tumors.

Objective To explore the role of receptor-interaction proteins(RIP) in phenethylisothiocyanate(PEITC)-induced apoptosis in human leukemia cells.Methods U937 cells were exposed to PEITC at various concentrations of 0,2,4,6 and 8 ?mol/L for 3 and 6 h,or at 8 ?mol/L for different time intervals of 1,3,6,9,12 and 24 h.Cells were stained with Annexin V/PI,and apoptosis was determined by using flow cytometry.Total protein extracts were prepared and subjected to Western blot assay using antibodies against poly(ADP-ribose)polymerase(PARP),Caspase-3,Caspase-8,and RIP.?-actin was used to ensure equivalent loading.Results After exposure to PEITC at concentrations of 2,4,6 and 8 ?mol/L for 3 h,U937 cells showed an increase in cell apoptosis(9% ,25% ,44% and 56% respectively).While when the time expanded to 6 h,the amount of apoptotic cells was increased to 16% ,28% ,51% and 82% respectively.A dose-dependent manner was seen when U937 cells were exposure to PEITC at different concentrations.When U937 cells were treated by PEITC at concentration of 8 ?mol/L for 1,3,6,9,12,and 24 h,the apoptotic cells covered 12% ,57% ,79% ,86% ,90% ,and 91% of all cells respectively,indicating a time-dependent manner.Western blot assay showed that PEITC caused the activation/cleavage of Caspase-3 and-8,and improved the PARP cleavage,and also decreased the expression of RIP.PEITC-induced apoptosis was proceeded by degradation of RIP.Conclusion Our results indicate that PEITC induces the apoptosis in human leukemia cells through a process that involves death receptor pathway,and RIP may play an important role in the apoptosis.

The binding complex of chemokine receptor CXCR4 and its specific ligand CXCL12 triggers the downstream signaling pathway to form biological axis of CXCR4/CXCL12. The axis plays an important role in homing, repopulation of hematopoietic stem cells, as well as maintenance of normal hematopoiesis and homeostasis of hematopoietic microenvironment. Meanwhile, CXCR4/CXCL12 axis is also closely related with relapsed leukemia, since it may promote survival, proliferation, metastasis and drug resistance in leukemic cells.The expression level of CXCR4 could be treated as an important marker for predicting prognosis in patients wizh leukemia, therefore, the combination of CXCR4 inhibitors with routine chemotherapy may represent a powerful approach for the treatment of leukemia.

BACKGROUND:Aclear understanding on the characteristics of contraceptive materials, techniques and effects on reproductive health is of great significance to reduce unwanted pregnancies and the abortion rate. OBJECTIVE: To summarize the progress, current situation and usage of the contraceptive materials, and to comprehensively analyze the characteristics, effects and adverse effects of intrauterine devices, subcutaneous contraceptive implants and tubal contraception materials, so as to provide the basis for women of childbearing age to choose safe and reliable contraceptive materials. METHODS:The related articles were retrieved from China National Knowledge Infrastructure and PubMed database during 1985 to 2015 by taking “intrauterine device, subcutaneous contraceptive implant, tubal contraceptive material, reproduction, health, contraceptive method” as the Chinese key words and taking “intrauterine contraceptive device, subcutaneous contraceptive implants, oviduct contraceptive, materials, reproductive health, influences” as the English key words. Finaly 44 articles were included in result analysis. RESULTS AND CONCLUSION:Intrauterine devices have a rapid development and wide audience, which are reliable, and mature to have a higher awareness and usage rate among females who have bred children. Subcutaneous contraceptive implants are characterized as strong affinity, constant release, good release effect, simple and convenient operation. Oviduct contraceptive suppository materials have strong biological nature, memory and tolerability, as wel as possess non-invasive, reusable, safe, long-term advantages. To seek safe, reliable contraceptive materials and methods with no adverse reactions is of great significance to ensure women’s reproductive health.

Objective To investigate the expressions of STAT3 and HIF-1α in esophageal squamous cell carcinoma (ESCC) and its relationships with clinical pathological characteristics and prognosis. Methods The expressions of STAT3 and HIF-1α protein were examined via immunohistochemistry in 50 cases of ESCC and normal esophageal mucosa tissue. Results In the immunohistochemistry of 50 ESCC , the positive expression rates of STAT3 and HIF-1α were 70% and 58%, respectively , significantly higher than those at the adjacent normal mucosa (P < 0.05). The expression of STAT3 in ESCC patients was significantly related to the lymph node metastasis, depth of invasion and TNM stage. The 30-month survival rates were positively correlated with the positive expression of STAT3 (P < 0.05). The expression of HIF-1α in ESCC patients was significantly related to the degree of differentiation and lymph node metastasis. The patients with HIF-1α negative had a higher cumulative survival rate than those with HIF-1α positive (P < 0.05), but the difference was not significant. STAT3 and HIF-1α were positively correlation with statistical significance (r = 0.362,P < 0.05). Conclusion STAT3 and HIF-1α are frequently expressed in ESCC. High expressions of STAT3 and HIF-1αmay contribute to the poor prognosis of human esophageal squamous cell carcinoma.
