Excellent mutilmedia courseware is the base to ensure teaching effect. Making excellent mutilmedia courseware by Director can make mutilmedia courseware more beautiful and have much more interaction and expressive force.

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.

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.

Acute myeloid leukemia (AML) originates from rare leukemia stem cells (LSC).Because these chemotherapy-resistant LSC are thought to underlie disease relapse,effective therapeutic strategies specifically targeting these cells may be beneficial.With the increasing knowledge regarding the LSC,several major directions in targeted therapies with regard to LSC are being investigated.These include targeting cell surface molecules,signal pathways,and microenvironment of LSC.Since eliminating LSC-should provide an efficient,potentially curative treatment option for leukemia patients,this article reviews the recent progress of LSC targeting in AML therapy.

Objective To investigate the role of zenapax in the prevention of acute rejection in renal transplant recipients.Methods The medical records of 50 renal transplant recipients treated with one dose of zenapax(study group) and simultaneously 30 renal transplant recipients without treatment of zenapax(control group) were retrospectively analyzed.The follow-up was six months.The incidence of acute rejection,renal allograft function,infection,and adverse effects of zenapax were comparatively analyzed between the 2 groups.Results Acute rejection rate was lower in study group(13/50,26%) compared with that in control group(17/30,57%;P)(0.05)).Conclusions One dose regimen of zenapax as part of immunosuppressive therapy is effective in the prevention of acute rejection in renal transplant recipients.It has less side effects and contributes to the improvement of renal allograft function.

Ultra-wide-field fluorescein angiography (UWFA) is a novel breakthrough in ocular fundus imaging technology, which can capture a single, high-resolution, 200° wide image of the ocular fundus that traditional fluorescein angiography cannot reach. This technology has important impacts on the screening, diagnosis, staging, treatment and follow-up of vascular diseases involving peripheral retina (such as diabetic retinopathy, age-related macular degeneration, retinal vein occlusion, uveitis and so on).

Fasting free fatty acids (FFA), plasma cortisol (F) were determined in newly diagnosed patients with type 2 diabetes. The results show that FFA, F and HOMA-IR are significantly higher in patients with type 2 diabetes than those in controls(all P

Objective To investigate the relationship between Pre-S1 antigen and hepatic function of the patients with chronic hepatitis B.Methods Serum samples of 300 cases with chronic hepatitis B patients were collected,Pre-S1 antigen and alanine aminotransferase (ALT),aspartate aminotransferase (AST) were checked,and the correlation were analyzed.Results Among 300 cases,patients with positive Pre-S1 antigen were 58.33％(175/300).In patients with positive Pre-S1 antigen,the abnormal ALT(＞40 U/L) detection rate was 78.75％ (138/175),the abnormal AST(＞40 U/L) detection rate was 77.17％ (136/175),Pre-S1 antigen negative patients ALT abnormal detection rate was 51.20％ (64/125),AST anomaly detection rate was 42.40％ (53/125).There was significant difference between two groups(x2 =2.875,5.223;P＜0.05).Conclusion In patients with chronic hepatitis B,Pre-S1 antigens can be used as a marker of hepatitis B virus infection,copy and hepatic cell injury.

Objective To evaluate the expressions of Survivin and Caspase-3 in patients with colorectal carcinoma and their association with tumor cell apoptosis.Methods The TdT-mediated dUTP nick end labelling(TUNEL) and immunohistochemistry were used to study cell apoptosis and expression of Survivin and Caspase-3 in 68 cases of colorectal cancer tissues and 20 normal controls.Results Survivin was expressed in 36 of 68(52.9%) cases of colorectal carcinoma and was not expressed in normal tissues.The expression of Survivin was significantly correlated with lymph node metastasis and histological type(P
