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.

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.

Objective To find antigens related with hepatocellular carcinoma(HCC).Methods Human Zinc Finger Protein 216(ZNF216) was identified by SEREX(serological analysis of recombinant cDNA expression libraries,SEREX).The 6His fusion protein of ZNF216 was expressed by bacteria and purified with a nickel affinity chromatography column.The level of anti-ZNF216 antibody in the sera was detected by ELISA,andZNF216 mRNA level in HCC tissue and its peripheral normal tissue was detected by RT-PCR.Results The level of anti-ZNF216 antibody in the sera of HCC patients was higher than that of healthy individuals.ZNF216 mRNA level in HCC tissue is evidently higher than peripheral normal tissue.Conclusion The over-expression of ZNF216 in the HCC sera and tissue indicates that ZNF216 perhaps plays a role in HCC.

Objective To establish a HPLC method to detect the propofol concentration of plasma in children undergoing cardiopulmonary bypass. Methods RP-HPLC with fluorescence detector was used in the study. Plasma samples were precipitated by the thymol-methanol solution, and centrifugated. 20?l of supernatant fluid was injected for analysis and separated by Dikma Diamonsil C18 column. The mobile phase was composed of acetonitril:water =56:44(V/V), flo rate was 1.0ml/min. Fluorescence detective wave lengths were ?ex= 276nm, ?em=312nm. HPLC machine was Agilent1100 series. Main column was Diamonsil C18(150?4.6nm,5um),guard column was Phenomenex Security(4mm?3mm). Results There was a good linear relationship within the range of 0.02～8.0mg/L(r=0.9993, n =9),the limit of detection was 5?g/L,average recovery was 96.99%,intra RSD(relative standard deviation )was between0.810% and 5.73%,inter RSD was between 0.932% and 7.337%. Conclusions The method is sensitive, simple, rapid, good linear relationship and precise. The experiment can be used for determination of propofol concentration in child undergoing cardiopulmonary bypass.

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.

[Summary] From November 2013 to March 2014, 3D laparoscopic operations were carried out in 14 cases in the department of urology of our hospital .The operation went smoothly , without conversions to laparotomy .The operation time was 54-466 min, with an average of 180 min.The intraoperative blood loss was 5 -400 ml, with an average of 70 ml.No pressure sores or operation complications occurred.The medical staff participating in the operation generally felt a good 3D vision, without sense of vertigo.We deem that during urological operations which have different operation postures , it is very important to protect both laparoscopic system and operation area from pollution .Timely and properly wearing 3D glasses, application of one-eye-detection method for lens sharpness , and the switching between 2D and 3D modes can reduce and relieve visual fatigue .

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.

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.
