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.

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.

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.

BACKGROUND:Integfin levels can affect cellular function,regulate bone formation and bone resorption.However,this process need activated by other factors,whether recombinant human bone morphogenetic protein 2 (rhBMP-2)has this effect is poorly understood.OBJECTIVE:To study the effects of the different concentration of rhBMP-2 on the expression of inergrin β_1 during the mandibular dfScraction in rabbits.DESIGN,TIME AND SETTING:The randomized,controlled.animal grouping experiment of histological observation was performed at the Animal ExperimentaI Center and Immunohistochemistry Center of Liaoning Medical University from May 2006 to May 2007.MATERIALS:A total of 45 Japanese white rabbits were used.rhBMP-2 was supplied by Beijing Academy of Military Medical Sciences.METHODS:The rabbits were prepared for mandibular distraction models and randomly assigned into control,1.5 mg rhBMP-2 and 3.0 mg rhBMP-2 groups.with 15 animals in each group.Collagen sponge and collagen binding proteins were implanted into mandibles of rabbits,respectively,and distraction 0.4 mm per time,twice per day for 5 days.The mandibles were lengthened 4 mm.MAIN OUTCOME MEASURES:The expression of integrin 131 was detected using immunohistochemistry at days 1,3,7,14,and 28 after distraction.RESULTS:All rabbits were included in the final analysis.The integdn β_1 mainly expressed at 7 days after distraction.At the same time point.when concenrtation rhBMP-2 was increased,the positive integrin β_1 rate and positive stained area percentage were increased(P<0.05).Compared to the same concentration,the positive integrin β_1 rate and positive stained area percentage were gradually increased as time prolonged (P<0.05).CONCLUSION:The integdn β_1 expression can be promoted by rhBMP-2 at the anaphase of mandibular distraction osteogenesis in a concentration-dependent manner.

Objective To investigate the hemodynamic characteristics of superior thyroid artery and its corresponding clinical significance with patients of Graves'hyperthyroidism.Methods Thirty patients with Graves'hyperthyroidism received Doppler ultrasonography.Patients were grouped with different serologic indices at 4 month after radioiodine therapy as relief(R),uncured(U)and hypothyroidism(H).The relationships between thyroid volume(V),superior thyroid artery peak systolic velocity(PSV),end diastolic velocity(EDV),RI,PI and systolic accelerating time(SAT)and the 4-month outcome were analyzed respectively.Results Besides the effect of 24 h-131I uptake rate on patients'short-term outcome,V,PSV and RI were of predominate prognosis value(P＜0.01).PSV and V of group R were positively correlated with 131I dose respectively(r1=0.825,r2=0.697;P＜0.001),while SAT of group R was negatively correlated with 131I dose(r=-0.489,P＜0.05).Conclusions Patients with high V,PSV and RI maybe still suffering hyperthyroidism after regular dosage of 131I therapy.Doses of 131I should be added appropriately for patients with high PSV and V,but short SAT to achieve complete remission,while it should be reduced for patients in opposite condition to avoid occurrence of hypothyroidism.

Objective To assess the diagnostic value of 3D-CE MRA for nutcracker syndrome (NCS).Methods The 3D-CE MRA appearances of 4 patients of NCS and control group ( 30 persons) were analyzed.Results The left kidney vein (LKV) crossed before abdominal aorta in 4 NCS patients and 30 controls- The average angle of the origin of the superior mesenteric artery (SMA) from the abdominal aorta was (84.50±3.60)° in control group,and became small (<30°) in 4 NCS patients.The distance of the origin of the SMA to the beginning of descent was (13.40±5.10) mm,and the SMA and abdominal aorta in the axial plane crossing the LKV was (16.40±5.10) mm in controls,and all decreased in 4 NCS patients whose LKV was obviously compressed.The average ratio of expansion to stenosis caliber of the LKV was 4,5 in 4 NCS patients,whereas 1.4 in the controls.Conclusion 3D-CE MRA can display relation between abdominal aorta,SMA and LKV,thus exactly diagnose the nutcracker syndrome.

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 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.

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.
