1.Newborn screening of inherited metabolic diseases by tandem mass spectrometry
Journal of Peking University(Health Sciences) 2006;38(1):103-106
Application of TMS technology in newborn screening has resulted in major expansion of disorder panel for metabolic diseases in recent years. This automated, multiplex testing methodology detects multiple analytes from single analysis of one blood spot, which leads to detection of 30-35 disorders of amino acids, organic acids, and fatty acids metabolism. The early identification of persons affected with inborn errors of metabolism has led to unexpected discoveries related to the natural history of the disorder or options for therapy. This article summarized (1) the basic principles of this technology and methodology. (2) Current status of application of this methodology in the United States, European countries and in China. (3) The positive impacts on the public health and advances in medical genetics. Finally (4) Challenges, issues and possible solutions. The purpose of this article aimed at introducing new technology and exploring the possibilities of implementing into developing countries where medical genetics is not developed and foreseeing the possible problems and obstacles.
2.Chemotherapy in aggressive T-cell non-Hodgkin lymphoma
Journal of International Oncology 2011;38(8):629-629
T-cell non-Hodgkin lymphoma is a group disease with unique clinical and pathological features. It is more aggressive and has lower chemotherapy sensitivity than B-cell lymphoma. In recent years, to search for effective treatment, novel agents such as gemcitabine, targeted therapy combined with chemotherapy and high-dose chemotherapy combined with hematopoietic stem cell transplantation are applied in the treatmentof T-cell non-Hodgkin lymphoma. And some progresses are achieved.
3.Radiotherapy of adult early-stage Hodgkin's disease
Chinese Journal of Radiation Oncology 2001;10(2):115-118
Objective To define the rational extent of radiation portal in adult patients with early-stage Hodgkin's disease (HD).Methods From Jan 1984 to Dec 1997,206 adult(≥15 year-old) HD patients with stage Ⅰ~Ⅱ lesions were admitted into the cancer hospital of Chimese Academy of Medical Sciences. 130 cases received radiotherapy alone (RT group). 76 cases radiotherapy combined with chemotherapy (R+C group). Involved-field (IF) was used in 7 patients (3.4%),mantle-field(MF) in 34 (16.5%) patients,subtotal nodal irradiation (STNI) in 140 (68.0%) and total nodal irradiation (TNI) in 25 (12.1%) patients. Kaplan-Meier method was used in survival analysis and log rank test for comparson.Results ①The overall 5-,10-year accumulated survival rates (ASR) were 85.1% and 73.2%. The 5-,10-year disease free survival rates (DFSR) were 68.0% and 63.6%, respectively.② The 5-year ASRs in the MF,STNI and TNI groups were 69.2%,93.3% and 94.4%,respectively (P<0.05);the 5-year DFSRs in these respective groups were 54.2%,79.2% and 79.9% (P<0.05).③ In R+C patients ,the 5-ASRs in the IF/MF and STNI/TNI groups were 75.7% and 90.6%(P<0.05); 5-year DFSRs were 43.1% and 73.3%(P<0.05).Conclusions The stage ⅠA patients with favouable prognostic factors can be cured by using mentle-field only,but patients in the other early-stages should be given subtotal nodal irradiatiion when radiotherapy is given alone. It is suggested that patients with unfavorable prognostic factors should receive radiotherapy combined with chemotherapy.
4.The clinical application of dual plane breast augmentation by areolar papillaris incision
Acta Universitatis Medicinalis Anhui 2014;(3):407-409
To analyze the effect of the treatment of dual plane breast augmentation ( one part of the implantation was located behind breast parenchyma and the other part was located behind the pectoralis majior muscle) use areo-lar papillaris incision. Using the areolar papillaris incision complete dual plane breast augmentation. For some breast potsis patients the superfluous areolar papillaris skin was removed and suspension fixation was performed at the same time. Some patients were followed up for 3-months to 2-years. All surgical outcomes were satisfactory with natural breast shapes, and there were no complications such as capsular contracture, prosthesis shift or burst. U-sing the areola papillaris incision can complete dual plane breast augmentation surgery without endoscopic guid-ance;surgery is simple under directvision.
5.Determination of 6 Kinds of Organophosphorus Pesticides in Water by Capillary Column Gas Chromatography
Journal of Environment and Health 1992;0(04):-
Objective To establish a method for simultaneous determination of 6 kinds of organophosphorus pesticides in water.Methods The liquid-liquid extraction,gas chromatography with RTX-50 capillary column and flame photometric detector were used to determine 6 kinds of organophosphorus pesticides(DDVP,dimethoate,malathion,methyl parathion,parathion,chlorpyrifos)in water.Results Chromatographic resolutions for the above 6 kinds of organophosphorus pesticides were both over 1.5.The linear range was 2.0-16.0 ?g/ml(r=0.999 2~0.999 8),the detection limits were 0.009 2~0.076 ng,RSDs were 1.5%-7.1%,the average recovery rates were 93.0%-98.7%.6 kinds of organophosphorus pesticides could be absolutely separated on RTX-50 capillary column.Conclusion This method presents an advantage in detection limit,precision and accuracy compared with that in GB13192-1991,it will meet the requirement of Sanitary Standard for Drinking Water and routine water quality analysis.
6.Comparison of the hepatic differentiation potential of human umbilical cord mesenchymal stem cells with bone marrow mesenchymal stem cells
Chinese Journal of Hepatobiliary Surgery 2016;22(1):13-16
Objective To compare the hepatic differentiation potential of human umbilical cord mesenchymal stem cells (UC-MSCs) with bone marrow mesenchymal stem cells (BM-MSCs).Methods UC-MSCs and BM-MSCs derived from passage 3 were induced by IMDM supplemented with 20 μg/L HGF and 20 mg/L α-FGF.The medium was changed twice a week.The concentrations of albumin and urea nitrogen from cultural medium were measured to compare the differentiation ability of the two cells.We also examined the expression of hepatic related genes by real-time RT-PCR.Results UC-MSCs manifested significandy stronger proliferation potential than BM-MSCs.Both UC-MSCs and BM-MSCs could be induced into hepatocyte-like cells.The morphology of UC-MSCs tended to be more mature than BM-MSCs and they had more cytoplasmic granules.After 4 weeks,the levels of albumin and urea nitrogen from the cultural medium of the UC-MSCs group were significantly higher than the BM-MSCs group (P < 0.05).Real-time PCR showed the expressions of four liver related genes CK18,G6P,HGF and ALB in the UC-MSCs group were significantly higher than the BM-MSCs group (P < 0.05).Conclusion UC-MSCs had higher hepatic differentiation potential than BM-MSCs.Thus,UC-MSCs are more suitable than BM-MSCs for tissue engineering in the treatment of end-stage liver diseases.
