Poly(U)-binding-splicing factor 60 KDa (PUF60), a U2-related splicing factor that facilitates 3′splice-site recognition at the early stage of spliceosome assembly.High expression of PUF60 is related to the occurrence of multiple tumors, such as colorectal cancer, ovarian cancer, gastric cancer, liver cancer, et al.PUF60 can regulate the expression of c-myc through the core-human transcription factor Ⅱ basal transcription factor.Anti-PUF60 antibodies are detected in the sera of patients with early-stage and recurrent tumor, and the levels are significantly decreased after the operation.PUF60 can be used as a combined or independent test index for the diagnosis of cancer, which can be a potential new target for gene therapy.

Objective:To provide some suggestions for improving the pharmaceutical advertisement supervision system and standardizing the pharmaceutical advertisement market. Methods: Literature reviews, statistical analysis and interviews were adopted to study the status quo and difficulties of pharmaceutical advertisement supervision and pharmaceutical advertisement trends. Results:The top-level design of pharmaceutical advertisements supervision sys-tem has two defects:the separation between approval and penalty and the obstacles to cooperation at all levels of the drug administration. The worsening status quo of illegal drug advertising has elicited concern from scholars and regu-lators. However, there are still some difficulties in the supervision of drug advertisers, advertising agents, and pub-lishers. Conclusion:It is suggested that the drug advertising regulation system should be perfected by strengthening information supervision, establishing a coordination mechanism and consolidating self-discipline consciousness. Addi-tionally, laws and regulations should be promptly revised as an essential way to improve the effects of supervision.

Breast cancer stem cells (BCSC) are group of cells exhibiting self-renewal and multi-directional differentiation potentials. These cells have an important role in the occurrence, development, metastasis, and recurrence of breast cancer. In normal circumstances, the ability of mammary stem cells to differentiate and undergo self-renewal is governed by related signaling pathways. After this mechanism is destroyed, breast stem cells undergo abnormal differentiation, forming breast cancer stem cells that unlimitedly proliferate to develop into breast cancer. As research on BCSC increasingly deepens, regulation of BCSC by notch signaling and its crosstalk with several signaling pathways have drawn a great deal of attention in this field. This paper reports the signaling pathways of breast cancer stem cells and latest studies on this field to better understand the essential role of notch signaling pathway in the occurrence and development of breast cancer and corresponding clinical targeted therapy.

The presence and persistence of systemic and lung inflammation in children with acute respiratory distress syndrome (ARDS) is the basis for the use of corticosteroids as a therapeutic agent.The trial of ARDS treated with high-dose short-course corticosteroids showed no benefit,even increase motality.At present,the results of randomized controlled trial and meta-analysis suggested that low-dose and replacement-dose methylprednisolone [1-2 mg/(kg· d)] or equivalent types of corticosteroids may decrease the fatality rate,reduce staying days in ICU and the duration of mechanical ventilation.Use of corticosteroids for ARDS in children is still lack of multicenter randomized controlled trial.

Objective To study the expressions and correlation of nuclear factor kappa B ( NF-B) p65 and trefoil factor family-3(TFF3) in gastric cancer,in order to evaluate the roles of NF-Bp65 and TFF3 in the occurrence and development of gastric cancer,and their correlation with Helicobacter pylori (Hp) infection.Methods The expressions of NF-Bp65 and TFF3 were detected by immunohistochemistey in 30 normal gastric mucosa specimens ,32 dysplasia specimens and 70 gastric cancer specimens .At the same time,the infection of Hp was detected .Results In normal gastric mucosa ,dysplasia and gastric cancer ,the expression of NF-Bp65 had a increasing tendency ( compared with the normal gastric mucosa group ,χ2 =18.632,44.291,all P<0.01).The expression of NF-Bp65 in gastric cancer group was higher than that in dysplasia group (χ2 =5.205,P<0.05).The expression of TFF3 in three groups also had a increasing tendency (compared with the normal gastric mucosa group ,χ2 =16.944,22.917,all P <0.01).The expression of TFF3 in gastric cancer group was higher than dysplasia group ,but there was no significant difference between the two groups (χ2 =0.162,P>0.05).In dysplasia group,the expressions of TFF3 and NF-κBp65 in Hp positive patients were significantly higher than those in Hp negative patients (P<0.01 or P<0.05).There was significantly positive correlation between expression of NF-Bp65 and TFF3 in gastric cancer group ( r=0.350,P=0.003).Conclusion High expressions of NF-Bp65 and TFF3 may be involved in an early event of gastric cancer . NF-Bp65 expression is positively correlated with the abnormal expression of TFF 3,both of which may be involved in the development and progression of gastric cancer .

This paper analyzes the cultural features in the titles of ancient traditional Chinese medical works and how do they affect the translation of these titles into English.explores the methods with which culture-rich titles of these works are rendered based on culture translating skills including transplantation.annotation,paraphrase and substitution with examples,and finally concludes several principles for translation of ancient traditional Chinese medical works into English.

With the development of funcgonal laboratory teaching,the advantages of integrating laboratory resources have been embodied in someway,improving the students'experiment level and their comprehensive analysis ability.But many new problems have also shown up such as unreasonable curriculum,construction of teaching staff.By reinstalling experiment courses,integrating the experiment teaching staff,and exploring the solution to the existing problems,the teaching quality of functional experiment can be promoted

0 05).Conclusion:Intraoperative lymphatic mapping with methylene blue is easily performed in early breast cancer patients.To determine the sentinel lymph node and status of axillary lymph node metastasis by pathological examination of the stained lymph nodes,there was hight false negative rate and unacceptable rate of misdiagnosis.So,its feasibility need further evaluation.[
