Hematopoietic Stem Cell Transplantation in Vietnam： Current Status and Future Directions

引用

Journal of Pharmacy and Pharmacology 2018年第8期6卷 765-771页

作者： Phu Duc vinh Huynh Man Van Huynh Nam Duy Hoang Ngon thien Huynh Tuan Xuan Ma Thu Hanh Nguyen Dung Chi Phu Binh Tan Nguyen Blood Transfusion Hematology Hospital Hochiminh city700000 Vietnam University of Medicine and Pharmacy Hochiminh city 700000 Vietnam

In recent years, there have been an increasing number of hematologic patients in Vietnam. Hematopoietic stem cell transplantation （HSCT） is fast becoming an effective method to cure many benign and malignant blood disorders. Nine transplant centers are operating throughout Vietnam. HCMC Blood Transfusion Hematology Hospital （BTH） is one of these centers where bone marrow, peripheral blood and cord blood stem cell transplantation were first conducted in our country. At BTH, half of the patients received allogeneic HSCT, mainly from matched sibling donors due to lack of a national bone marrow donor registry. While acute myeloid leukemia was a common indication of allogeneic HSCT, most of the patients undergoing autologous HSCT had multiple myeloma. One major issue we encountered concerned bacterial and fungal infections during neutropenia period. Because of an endemic area, CMV reactivation frequently occurred. Five-year overall survival （OS） and event-free survival （EFS） were 47% and 46%, respectively. To create more opportunities for patients, our future directions will focus on some new transplant procedures, such as haploidentical, unrelated and cord blood transplantation.

Journal of Environmental Protection 2016年第8期7卷 1113-1118页

作者： Vo thi Anh Tran Khanh Minh Trinh Van Giap Ha Lan Anh Nguyen Thanh Cong Nguyen Hong thinh Vu Hoai Institute for Nuclear Science and Technology Hanoi Vietnam vinh University Vinh Vietnam

The surface water in the southern of Hanoi capital is researched by identifying δ2H and δ18O stable isotopes together with EC, DO, BOD5, COD, TSS. Surface water samples for studying include the Red river, Nhue river and Kim Nguu river, Thanh Nhan lake, Yen So lake and Van Quan lake were collected in the dry season (April) and the rainy season (August) in 2015. The stable isotope analysis results showed that the δ18O values is a range from -42.53‰ to -64.05‰ and, the δ2H values is the range from -5.09‰ to -8.79‰ under global meteoric waterline (in the water vapor region). The δ2H results of the rivers and lakes in the dry season are more negative than the rainy season with a small difference. The δ18O results of lakes in the dry season are more negative than the rainy season, but the δ18O results of river in the dry season are more positive than the rainy season. The results of the EC, BOD, COD, DO, TSS analysis showed that surface water environment has changed clearly in the two seasons and the contamination level in the dry season is usually higher than the rainy season. The lakes and rivers strongly influenced by human activities led to seriously pollution are Van Quan lake and Yen So lake, Nhue river and Kim Nguu river.

Essential oils obtained from hydrodistillation of three medicinal plants grown in Vietnam were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). The monoterpene hydrocarbons, α-pinene (50.2%), β-pinene (23.6%) and limonene (5.3%) were the most abundant constituents of the rhizome oil of Zingiber collinsii Mood & Theilade (Zingiberaceae). The main compounds of the stem oil of Croton kongensis Gagnep., (Euphorbiaceae) were benzyl benzoate (12.7%), β-selinene (9.8%), bulnesol (8.0%) and 5,6,7,8-tetrahydroquinoxaline (7.4%). The leaf oil of Goniothalamus albiflous Ban., consisted mainly of α-pinene (26.2%), caryophyllene oxide (10.6%) and 1,8-cineole (9.7%). The composition of the oils of Zingiber collinsii and Croton kongensis was being reported for the first time.

AIM To investigate rates of distant metastases(DM) detected with [18]fluorodeoxyglucose-positron emissiontomography/computed tomography(^(18)FDG-PET/CT) in early stage invasive breast *** We searched the English language literature databases of PubM ed, EMBASE, ISI Web of Knowledge, Web of Science and Google Scholar, for publications on DM detected in patients who had ^(18)FDG-PET/CT scans as part of the staging for early stages of breast cancer(stage Ⅰ?and Ⅱ), prior to or immediately following surgery. Reports published between 2011 and 2017 were considered. The systematic review was conducted according to the PRISMA *** Among the 18 total studies included in the analysis, the risk of DM ranged from 0% to 8.3% and 0% to 12.9% for stage Ⅰ?and Ⅱ invasive breast cancer, respectively. Among the patients with clinical stage Ⅱ, the rate of occult metastases diagnosed by ^(18)FDG-PET/CT was 7.2%(range, 0%-19.6%) for stage ⅡA and 15.8%(range, 0%-40.8%) for stage ⅡB. In young patients(lence of DM at the time of diagnosis for those with aggressive histology(i.e., triple-negative receptors and poorly differentiated grade).CONCLUSION Young patients with poorly differentiated tumors and stage ⅡB triple-negative breast cancer may benefit from ^(18)FDG-PET/CT at initial staging to detect occult DM prior to surgery.

试验旨在利用4种类型的方法,即显微镜观察、滚管法、实时PCR和PCR-DGGE法研究4头安装有瘤胃瘘管的沼泽地水牛(Bubalus bulalis)瘤胃微生物数量及其多样性。所有的水牛随机分组,试验为2因子2水平,利用4×4拉丁方设计,试验处理日粮为4种。因子A为2种粗料日粮(稻草、尿素和2%石灰处理的稻草),因子B为精料中添加2种水平的尿素(0和4%尿素)。另外,通过评价瘤胃的发酵参数来估算瘤胃微生物变化和瘤胃发酵效率之间的关系。试验结果表明,尿素和石灰处理的稻草和含有4%尿素精料混合物物组中的总瘤胃细菌、***,***和真菌的数量大于其他处理组,然而***和原虫数量显著降低(P<0.05),所有处理组中淀粉降解菌、蛋白降解菌和总细菌数量无显著差异。瘤胃产甲烷菌的数量随处理而减少但其多样性在每个泳道的18个不同条带间无明显变化。瘤胃pH、NH3-N,BUN浓度、乙酸和丙酸的含量随牛采食尿素和石灰处理的日粮及含4%尿素精料而显著升高(P<0.05)。基于以上研究可以说明,尿素和石灰处理的稻草和含4%尿素的精料的混合日粮会提高水牛瘤胃发酵效率、瘤胃降解纤维微生物的数量,从而瘤胃生态环境。
