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: 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.

Natural killer cells are the key effector cells in innate immune response,playing the role in pathogen clearance and tumor immunosurveillance by cytokine secretion and cytotoxicity.Hematopoietic stem cells go through developmental intermediates to generate mature NK cells under the progressive regulation of extrinsic factors and intrinsic factors.In the past thirty years, great progresses have been made in the developmental progress,niches,regulation of NK cells and the relationship between NK cells and dis-eases.In this review,we will discuss in detail the molecular mechanisms of NK cell development and the diseases caused by functional compromise of NK cells.

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.

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

Methods for the collection and processing of Lonicera japonica and comparison of the quality of the endproducts obtained by different methods were reported.

Objective The sponge of the small intestinal submucosa(SSIS) is established by the material chemistry,in order to supply the database for the scaffold of the dermic tissue engineering.Methods At the regular temperature,the SSIS was conducted firstly by the physiochemical method.Then,the SSIS was crosslinked by the 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) so as to get the three dimentional SSIS.The morphological feature was obtained by the lighting and electron microscope,ophthalmic oberservation,the embedding in the mouse of the SSIS was used to observe the adsorbing and immunology.The results were analyzed by statistic software.Results The crosslinked SSIS was regular in the structure and not loosen,the framework was equilibrium,the pore was abundant with the diameter of the 100 ～ 200μm,the difference was obvious (all P ＜ 0.05).The firstweek after embedding did not exist the adherence leukocyte infiltration,the vascularization occur in the third week.The material was completed and had no elastic degradation.Conclusion Reconstructed SSIS has completed structure,elastic with the vascularization and minor immunology,which could be used as the extracellular scaffold for the dermic tissue engineering.

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.
