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.

Recent researches revealed that intestinal flora contribute to the development of metabolic syndrome, espe?cially to the disorder of their targeted cardiovascular system. Blood cholesterol level is affected by the metabolism of intesti?nal flora in cholesterol and bile acid. At the same time, the blood cholesterol level is the key player in development of athero?sclerosis. This review mainly discussed the relationship between the intestinal flora dependent metabolite trimethylamine ox?ide (Trimetlylamine oxide, TMAO) and atherosclerosis.

Objective To observe the change of peripheral blood lymphocytes subsets in patients with active ulcerative colitis (UC) and explore its clinical significance. Methods The clinical data and lymphocyte subsets of 40 active UC patients who admitted to the Department of Gastroenterology, Peking University First Hospital,from June 2007 to January 2010 were retrospectively analyzed. Patients who had previously used immunosuppressants or tumor necrosis factor monoclonal antibody were excluded. Seventy-nine subjects with health examination served as controls. Peripheral blood lymphocyte subsets detected included total T cells, CD4 + T cells, CD8 + T cells, B cells, and NK cells. Only the first detection results of UC patients were used for analysis. Results The proportion of total T cells for UC patients (73.60% ± 8.35% ) was significantly higher than the controls (69. 76% ±7.37%) (P =0.012). CD8+T cell ratio (35.53% ± 10.99%) was significantly higher than the controls ( 30. 56% ± 6. 75 % ) ( P = 0. 011 ). When the UC patients were stratified according to inflammatory involvement,the total T cells, CD8 +T cell, and NK cell ratio were significantly different among pancolitis, non-pancolitis, and the controls ( all P ＜ 0. 05 ). When the UC patients were stratified according to the disease course, the total T cells and CD8 + T cell ratio were significantly different among chronic recurrent/persistent, onset, and the controls ( both P ＜ 0.05 ). When the UC patients were stratified according to the extraintestinal manifestations, the total T cells and CD8 + T cell ratio were significantly different among those with extraintestinal manifestations, those without extraintestinal manifestations, and the controls ( both P ＜ 0.05 ). Conclusions The proportion of total T cells and CD8 + T cells increase in UC patients. Such immune abnormalities are even more distinctive in those UC patients who suffer from pancolitis or chronic recurrent/persistent type or those with extraintestinal manifestations.

Objective To study on extraction and characteristics of ?-glucosidase inhibitor from Chlorella vulgaris.Methods The extracts were prepared by drying,degreasing and silica gel columniation washing with different organic solvents,and its pure degree and components were identified.The activities of the inhibitor and its effects on ?-glucosidase under different conditions were studied.Results The results showed that ?-glucosidase inhibitor from Chlorella vilgaris may be a kind of substance of hydroxybenzene.Conclusion The inhibitor showed potent inhibitive effection on ?-glucosidase,and belong to a mechanism of noncompetitive inhibition

Objective To investigate the efficacy of conservative treatment with laparoscopy for patients with ectopic pregnancy.Methods From January 2000 to December 2005,76 patients with ectopic pregnancy received conservative treatment by laparoscopy in our hospital.The data of the patients were analyzed retrospectively.Results In this series,fenestration of the Fallopian tube was performed on 42 cases,salpingostomy on 21,fimbrial expression on 8,and segmental resection and end-to-end anastomosis on 5.Salpingography showed that the Fallopian tube was patent after the operation in all of the patients.The mean operation time was(58.5?19.4) minutes(ranged from 35 to 105).The serum level of ?-hCG decreased to a normal range in 3 weeks postoperation.Follow-up was available in 61 cases for 1 year,during which 35 of the cases(57.4%,35/61) had intrauterine pregnancy;2(3.3%) had spontaneous abortion,and 2(3.3%) showed ectopic pregnancy;the other 22(36.1%) had no pregnancy.Conclusions Conservative treatment by laparoscopy is safe and effective for ectopic pregnancy.To avoid repeated ectopic pregnancy,?-hCG monitoring after the operation is necessary.

Through the network medical teaching and guidance system,the live video of clinical medicine activity can be multicast by MPEG2 code and MPEG4 code simultaneously on the LAN or WAN.It may meet the request of different network bandwidth,realize the bidirectional audio or video frequency at the same time,and satisfy the clinical teaching or guidance need.The client port can be deployed in the random terminal on LAN or WAN,while the user with the authorization can see the high clear surgery image in real time at any place,make communication through the bidirectional audio and video system,and even remotely control the camera's lens angle and focus for perfect video effect.

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.

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.
