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.

Human papillomavirus is an oncogenic DNA virus and has more than 90 subtypes. High risk types (HPV 16, 18, 33) are associated with many kinds of malignant neoplasms of head and neck. The HPV DNA can induce mutations of p53, RB genes and increase cell transformation and over proliferation. The frequences of HPV positive are different in malignant neoplasms from different head and neck sites. HPV was more often detected in squamous cell carcinoma of oral cavity, oropharynx and larynx. In nasopharyngeal carcinoma, adenocarcinoma or lymphoma, the expression of HPV was quite low. The detection of HPV in cervical metastatic lymph nodes can improve diagnosis of primary sites.

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 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.

With the rapid development of critical care medicine (CCM) in China, there are increases in the number of intensive care units (ICUs), the scale of one center ICU and the team. Subspecialty construction of CCM is of great concerns for personnel training as well as discipline development, and is currently one of the urgent problems that need to be resolved. Experience of CCM subspecialty construction from Europe and the United States is lacking and it is necessary to propose some opinions on innovation to construct CCM subspecialties with Chinese characteristics. We believe that CCM sub-specialties construction should be based on the core knowledge (pathophysiology) and skill (organ monitoring and support). The following 7 sub-specialties can be set up: ① acute lung injury and mechanical ventilation; ② shock, hemodynamic monitoring and treatment; ③ acute kidney injury and blood purification; ④ sepsis and anti-infective therapy; ⑤ stress, sedation and analgesia; ⑥ nutrition and metabolic support; ⑦ coagulation, immune and inflammation. The core knowledge and skills of critical care medicine will constantly be updated and enriched. Therefore, sub-specialty settings should be constantly updated as well.

Objective To study on the correlation between plasma homocysteine (Hcy),folate acid(FA) and vitamin B12(VitB12) levels and vascular dementia (VD).Methods To measure plasma Hcy, FA and vitamin B12 in 96 patients with VD ,in 152 non-dementia cerebrovascular disease ( NDCVD ) and in 80 normal controls re-spectively,and results werw compared between each two groups by using student test .Cognitive status was evaluar by using mini mentai state examination(MMSE).The effect of Hcy,FA and VitB12 on VD and its cognitive function were analyzed.Results The levels of plasma Hcy in VD and NDCVD were higher than those in normal control grop ,and there was significantly difference (t=3.26,3.14,all P<0.01),and the best high one is VD;The levels of plasma FA and VitB12 in VD and NDCVD were lower than those in normal control grop ,and there was significantly difference ( t=3.16,2.98,3.21,2.91,all P<0.01),and the best low one is VD.The levels of plasma Hcy concentrations were in-creased and MMSE scores were decreased with severity of dementia , and there were negative correlation between MMSE scores and plasma Hcy concentrations (r=-0.69,P<0.05).Conclusion The levels of plasma Hcy corre-lated with VD.High-Hcy is one of possible rise factor for VD in senior .Both low-FA and low-VitB12 were indirect fac-tors for VD.

Neonatal respiratory distress syndrome (RDS) is most common in premature infants,the smaller the gestational age,the higher the incidence.Continuous positive airway pressure (CPAP) started in the delivery room has been shown in multicentre randomized controlled trials to reduce the need for mechanical ventilation (MV) and surfactant.The European Consensus Guidelines on the Management of Neonatal Respiratory Distress Syndrome in Preterm Infants-2013 Update recommended that CPAP should be started from birth in all babies at risk of RDS and a starting pressure of at least 6 cmH2O(1 cmH2O =0.098 kPa)should be applied.CPAP with early rescue surfactant should be considered the optimal management for babies with RDS.Using CPAP immediately after birth with subsequent selective surfactant administration may be considered as an alternative to routine intubation with prophylactic or early surfactant administration in preterm infants.If endotracheal intubation is needed,early administration of surfactant is preferable.Nasal intermittent positive pressure ventilation may reduce the risk of extubation failure in babies failing on CPAP.Several strategies have been employed specifically to improve the success of noninvasive ventilation and shorten the duration of MV.Caffeine should be used to facilitate weaning from MV and to reduce bronchopulmonary dysplasia.A short tapering course of low-or very low-dose dexamethasone should be considered to facilitate extubation in babies who remain on MV after 1 ～ 2 weeks.Very early steroid treatment and treatment with high doses cannot be recommended.
