In order to further promote friendly cooperation with developing countries, Chinese government has been committed to increasing the intensity of cooperation and human resource development among developing countries. Healthcare is one of the key areas of China’s foreign aid. This article described the general conditions and experiences of national foreign aid training projects for developing countries undertaken by the Beijing Traditional Chinese Medicine Hospital and Beijing Traditional Chinese Medicine Research Institute. From aspects of participant enrollment, training program implementation, and training feedback, the training mode of national foreign aid on traditional medicine was introduced. This article focused on the selection of teachers, preparation of professional textbooks, and evaluation of teaching quality. Training programs over the years were guided by clear training concepts and accurate goal settings, which provided a useful exploration for the personnel training mode of national foreign aid on traditional medicine.

In order to improve the speech quality and auditory perceptiveness of electronic cochlear implant under strong noise background, a speech enhancement system used for electronic cochlear implant front-end was constructed. Taking digital signal processing (DSP) as the core, the system combines its multi-channel buffered serial port (McBSP) data transmission channel with extended audio interface chip TLV320AIC10, so speech signal acquisition and output with high speed are realized. Meanwhile, due to the traditional speech enhancement method which has the problems as bad adaptability, slow convergence speed and big steady-state error, versiera function and de-correlation principle were used to improve the existing adaptive filtering algorithm, which effectively enhanced the quality of voice communications. Test results verified the stability of the system and the de-noising performance of the algorithm, and it also proved that they could provide clearer speech signals for the deaf or tinnitus patients.

BACKGROUND:Sclerostin can negatively regulate the bone metabolism, and the sclerostin monoclonal
antibody can antagonize the negative regulation effect, inhibit bone resorption and promote bone formation. OBJECTIVE:To explore the mechanism and application progress of sclerostin monoclonal antibody in the treatment of osteoporosis.
METHODS:An online search of PubMed database, CNKI database, VIP database and Wanfang database
between May 2005 and May 2013 was performed by the first author to search the related articles with the key words of“osteoporosis, antibody, sclerostin, Wnt, SOST”in both English and Chinese. Articles related to
sclerostin monoclonal antibody were included. For the articles in the same field, those published earlier or in the authorized journals were preferred.
RESULTS AND CONCLUSION:A total of 170 articles were obtained after initial search, and final y 54 articles related to sclerostin monoclonal antibody were included for review according to the inclusion criteria. The
sclerostin can block Wnt pathway through combining with low-density lipoprotein receptor-related protein 5/6, thus inhibiting the differentiation and mineralization of osteoblasts. By specifical y binding to sclerostin, the
sclerosin monoclonal antibody can indirectly promote bone formation and restrain bone absorption which has great significance in the treatment of osteoporosis. Meanwhile, compared with the other treatment method, the specific targeting of sclerostin and the binding specificity of sclerostin monoclonal antibody provide application advantages for the treatment of osteoporosis.

Sepsis is systemic inflammatory response syndrome associated with infection.Early recognition of severe sepsis or septic shock,early hemodynamic resuscitation and the immediate initiation of effective intravenous anti-infective therapy are the cornerstones in the management of patients with sepsis.The infectious microorganisms associated with sepsis in pediatric patients vary with the patient's age and immune status.Initial empirical antimicrobial therapy should include one or more drugs that have activity against all likely pathogens and that penetrate in adequate concentrations into the presumed source of sepsis.Empirically therapy should be de-escalated to the most appropriate single therapy as soon as the susceptibility agent is known.

The combination of medical humanistic spirit and medical scientific spirit is the sign of the maturity of medicine.The modern medical mode of ' biology-psychology-society-environment' sets new requirements for medical humanistic education.Clinic medical postgraduates,the front -line medical workers,play a very important role in medical work,but they show huge deficiency in interpersonal communication,humanistic knowledge and humanistic possession nowadays.The paper tried to draw some lessons from the successful education mode of George Washington university and discussed practicable methods to improve humanistic education among medical postgraduates aiming at cultivating qualified medical workers who have both noble medical ethics and perfect medical technology and ability.

Along with several decades development,the urinary and male genital system neoplasm has gained distinguished research achievements in China.The research output is being historically high.However,our ability of treatment and diagnosis cannot meet people's requirement of health due to the serious prevalent situation.It is necessary for China to take actions to keep up with the advanced world level.

Gastrointestinal motility disorders are in high incidence in children.Due to moderate prokinetic effects,poor symptomatic responses and the presence of adverse effects,there is a clear need for new classes of prokinetics.Currently available drug classes in adult include antidopami-nergic agents,serotonergic agents,and motilin-receptor while there are less available drug classes in children.The aim of the present article is to review and address the present use of promotility drugs in the treatment of different gastrointestinal motor disorders,as well as the potential for future developments.

Myeloid-derived suppressor cells (MDSCs) play an important immunosuppressive role during the tumor development process.And the progression of many tumors are always accompanied with abnormal accumulation of MDSCs.Moreover,both the accumulation and functions of MDSCs could be affected by complicated factors.Therefore,how to effectively reduce the immunosuppressive effects of MDSCs in oncotherapy has become the focus of scholars.Recent studies show that anti-tumor drugs can affect many biological behaviors of MDSCs.

BACKGROUND: Disturbance of lipid metabolism is responsible for many kinds of diseases, and to screen safe and effective prescription for lipid reduction has clinical significance.OBJECTIVE: To study the influence of puerarin-arginine composition on lipid metabolism in rats.DESIGN: Comparative observing study based on animal model.SETTING: Experimental animal center and department of biochemistry in a military hospital of Chinese PLA.MATERIALS: This study was carried out at the Experimental Animal Center and Department of Biochemistry of the General Military Hospital of Chinese PLA between May and August 2004. Eighty Wistar rats were randomly divided into high dosage, middle dosage, low dosage group and control group with 10 male and 10 female rats each.METHODS: Rats took food freely, and experimental groups were supplemented with puerarine-arginine composition of different dosage (0, 0.93,1.39 and 1.85 g/kg) for observing the influence on rats.MAIN OUTCOME MEASURES:① blood parameters; ② change of body mass and utilization rate of food; ③ parameters of vital organs;④histopathological changes.RESULTS: From onset of the second week, body mass of both male and female rats in experimental groups were found obviously lower than those in control group. The levels of blood cholesterol in female rats were(1.63 ±0.20) and (1.29 ±0.23) mmol/L in 0.93 g/kg dosage group and control group respectively, and were(1.75 ±0. 13) and(1.31 ±0. 19) mmol/L in male rats,and both have statistical significance( F = 6.43, 6. 58, P ＜ 0. 05).Fatty parameters of the three experimental groups were found obviously lower as comparing with those of control group.CONCLUSION: Such composition has been proved to be able to exert function in lipid reduction by decreasing body mass, and improving utilization rate of food and proportion of cholesterol and organic fat.
