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.

The changes of lysosomes of the hepatocytes in 27 healthy female rats aged 1, 5, 15, 30, 50, and 90 days respectively were observed on morphometry and by studying the ultrastructures with electron microscope. The results are as following:1. The volume density and numerical density of the lysosomes of rat hepatocytes are markedly increased as the age increases.2. The lysosomes originally scattered in cytoplasm gradually migrate to the periphery of bile canaliculi.3. The proportion among certain forms of secondary lysosome changes as the rats grow older and the alteration of autophagic vacuoles is more prominant than others.The significance of the lysosome changes mentioned above was discussed. The author, considering from all the results, suggests that the time around five days after the birth of the rats is a critical period for the development of the lysosomes of rat hepatocytes.

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.

Acute myeloid leukemia (AML) originates from rare leukemia stem cells (LSC).Because these chemotherapy-resistant LSC are thought to underlie disease relapse,effective therapeutic strategies specifically targeting these cells may be beneficial.With the increasing knowledge regarding the LSC,several major directions in targeted therapies with regard to LSC are being investigated.These include targeting cell surface molecules,signal pathways,and microenvironment of LSC.Since eliminating LSC-should provide an efficient,potentially curative treatment option for leukemia patients,this article reviews the recent progress of LSC targeting in AML therapy.

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.

Myeloid-derived suppressor cells (MDSCs) play an important immunosuppressive role during the tumor development process.And the progression of many tumors are always accompanied with abnormal accumulation of MDSCs.Moreover,both the accumulation and functions of MDSCs could be affected by complicated factors.Therefore,how to effectively reduce the immunosuppressive effects of MDSCs in oncotherapy has become the focus of scholars.Recent studies show that anti-tumor drugs can affect many biological behaviors of MDSCs.

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.

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.
