Breast cancer metastasis suppressor 1(BRMS1)can suppress the tumor cells metastasis. and significantly reduces the metastasis without affecting tumor growth. The relevant mechanism(s)may be related to intercellular communication, phosphoinositide signal transduction and interaction with NF-KB, and so on. Therefore, exploring the mechanisms of inhibition of tumor metastasis might be helpful for use of BRMS1 as tumor gene therapy.

Totally digitalized B-ultrasonography is the tendency of the development of ultrasonic medical instruments. Its basic technical characteristic is realizing real-time processing of the extremely huge ultrasonic data with digital electric circuit. This paper summarized the tendency of development and the primary techniques of signal processing, which including dynamic filtering, log amplification, envelope detection and secondary sampling. Furthermore, various techniques in different procedure of signal processing are introduced in detail.

Objective:To establish hospital infection data sharing and service platform for collecting and issuing the hospital infection data. Methods:The relational database was used to realize data storage and J2EE light structure was employed to enhance the development and the operating efficiency and flexibility of the system according to the principles of Web information system.Results and Conclusion:An open and sharing hospital infection data platform for data processing, retrieving and analyzing was established. The established hospital infection data set and surgery infection data set contained more than 20 000 records. The system provided an effective software platform support for the utilization of hospital infection data and the prevention and control of hospital infection. This article introduces key technologies of the design and realization of the system.

Objective To investigate the expression and significance of Peripheral blood of Toll-like receptor-4 and cytotoxic T lymphocyte-associated antigen-4 in patients with essential hypertension. Methods We selected 35 patients with hypertension and 20 healthy people.We used flow cytometry to investigate TLR4 expression levels, and ELISA to detect the expression of CTLA-4. Results TLR4 expression in peripheral blood of patients with hypertension was (8.63 ±1.16)%, significantly higher (5.27 ± 1.25)%.The difference was statistically significant (t = 6.16,P < 0.05); CTLA-4 expression in peripheral blood of patients with hypertension was significantly higher (P<0.05); Hypertensive patients with CTLA-4 positive rate and TC, LDL-C was positively correlated (P<0.05); TLR4 and CTLA-4 was positive correlation (r = 0.886,P < 0.05). Conclusions TLR4 and CTLA-4 were high expression in hypertensive patients with hypertension,and related to hypertension.

The paper described the building of a nursing team in a newly built hospital.The process consists of setting up the nursing department in advance and developing rules and regulations;enhancing nurse rotations and training to enhance their professionalism; building a seamless communication to make a supportive environment and sense of belongings; enhancing education of professional spirit to train the nurses to respect their career.All these provide the hospital with solid support of nursing team building.

Zn. Conclusion Human activities developed along the Huaihe River does not influence the concentration of heavy metals in the sediment, no serious contamination of heavy metals in the sediment is found in the present investigation.
