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 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.

Objective To discuss the expression and its significance of neuron specific enolase(NSE) and soluble-protein 100(S100) in Hirschsprung′s disease(HD) and its allied disease.Methods Clinicopathologic data were reviewed from 120 cases of suspected HD patients.According to the morphological characteristic of the nerve stanza cell stained with HE under the microscope.NSE and S100 immunohistochemical staining was performed in 29 cases.Then we compared the effect of the staining with analyzed the distribution.Results The number of the nerve plexus and ganglion cell of allied HD was significantly higher than that in normal control group(P

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

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.

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.

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 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.
