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.

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).

Organophosphate pesticides(OPs)are used extensively in agriculture,it became the most heavily used insecticides in China after the use of organochlorine pesticide was restricted in 1980s in China.Recent years,with an increasing usage of organophosphate pesticides in China,much concern has been showed for the level of OPs in human body and the adverse effects of OPs on human health especially on fetuses and children have raised a great.The level of OPs in children and the adverse effects of OPs exposure on neurobehavioral development of children were reviewed in the present article.

According to the concept of sagittal spinal balance, the alternating curves of cervical and lumbar lordosis and thoracic and sacral kyphosis enable the head to be positioned over the trunk and pelvis. But the sagittal imbalance represents departure from this ideal form. Cervical kyphosis may represent the most disabling of these imbalances, for it can cause pain, postural difficulties, or neurologic deficit. A summary and discussion is reviewed regarding the anatomy, biomechanics, etiology, clinical presentation, laboratory examination and treatment of this condition.

Objective Analyse and report the diagnosis and treatment process of vulvar epithelioid sarcoma, it provides a basis for rare case in clinic. [Methods] Through the analysis of the patient's il ness, treatment, and pathology examination, and the effect of the treatment of prognosis of vulvar epithelioid sarcoma of the summary, truly record the occurrence of vulvar epithelioid sarcoma development, treatment and prognosis. [Results] The intraoperative pathologic examination in patients diagnosed the vulvar epithelioid sarcoma, and it used the removal of expanding. Now the patient is not recurred. [Conclusion] Vulvar epithelioid sarcoma is clinical y rare, needs combined with immunohistochemical examination at the time of diagnosis, removal of local expansion is the effective method to treat, it is not exactly curative effect of chemotherapy and radiotherapy.

0.05)。But the DNA,RNA content and lactase activities and maltase activity in the small intestine mucosa in I-fed piglets were significantly greater than those of P-fed piglets. Conclusions:These results show that insulin influences the enzymatic activity and the proliferation of intestinal epithelial cells of IUGR newborn piglets.

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 observe the effects of pregnancy induced hypertension on lipid metabolism and bilirubin metabolism in term neonates.Methods 200 term neonates were selected and divided into the two groups,100 cases whose mother were healthy were control group and another 100 cases whose mother had gestational hypertension were observation group.Birth weight,measured in cord blood triglyceride (TG),total cholesterol (TC) levels,high density lipoprotein (HDL-C),low density lipoprotein (LDL-C),adiponectin (APN) level were recorded.Results Birth weight of the observation group had significantly lower birth weight (2 927 ± 492) g,than the weight of the control group (3 452 ± 348) g.The incidence of lower birth weight was higher than in the observation group.TG,LDL-C levels of the observation group were (0.6 ± 0.24) mmol/L,(1.95 ± 0.25) mmol/L,were higher than those of the control group[(0.39 ± 0.17) mmol/L,(1.95 ± 0.25) mmol/L].There was a statistically significant difference between the groups (t =12.35,2.35,P ＜ 0.01 or P ＜ 0.05).HL-C and APN of the observation group were lower than those of the control group (t =1.79,7.00,all P ＜ 0.05).Bilirubin after bomed 24 hours,48 hours,72 hours and bilirubin peak of the observation group were (8.64 ± 2.17) mg/L,(11.06 ± 3.12) mg/L,(10.32 ± 2.47) mg/L,(12.04 ± 2.13) mg/L and were higher than those of the control group [(3.06 ± 0.94) mg/L,(6.98 ± 1.56) mg/L,(7.26±1.89)mg/L,(9.64±1.98)mg/L](t=23.48,11.65,9.84,8.27,allP＜0.01).Conclusion Maternal PIH may affect birth weight,lipid metabolism and bilirubin metabolism.
