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 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.

Objective To explore the value of ultrasonography in the diagnosis and identification of Obstetrics and Gynecology in accident and emergency.Methods A retrospective method was taken to 80 cases of obstetrics and gynecology emergency patients with ultrasound diagnosis data analysis in the hospital from June 2014 to June 2015,and compared to surgical and pathological diagnosis,to observe the ultrasonic diagnosis value.Results The correct rate of the ultrasound diagnosis of ectopic pregnancy,ovarian cyst torsion,inevitable abortion,threatened abortion,corpus luteum rupture,trophoblastic disease,and acute pelvic inflammatory disease was 90.9％,94.1％,100.0％,100.0％,85.7％,75.0％,and 100.0％,and the overall diagnostic accuracy was 93.8％.Conclusions The Emergency Department of obstetrics and gynecology patients used ultrasound has a better diagnosis effect,and high diagnostic accuracy.At the same time,the ultrasound examination is gynecology and obstetrics emergency check the preferred way,strong repeatability,and better observed lesions,high application value.

[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 .

The measures taken by Library of Southern Medical University to improve the use of its electronic re-sources were described according to the major problems in use of electronic resources in domestic college and uni-versity libraries from resources assessment, resources integration and revealing, resources popularization and librarians support, with certain rational suggestions proposed for increasing the utilization ratio of electronic resources, inclu-ding popularization of resources, training of user information literacy, and improvement of users ability.

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.

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.

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.

The incidence of breast cancer has markedly increased in recent years.Breast cancer has become a major cause of death of adult females.Many studies have shown that glucose metabolism disorders and its connected factors have been closely related to occurrence and development of breast cancer.Regulation of glucose metabolism and related factors may become an important way in prevention and treatment of breast cancer.

Objective: To observe the role of nutritional support in treatment of chylous leakage after thyroid carcinoma operation.Methods: The parenteral nutrition combined with somatostatin and re-operation was used in treatment of 2 cases of chylous leakage after thyroid carcinoma operation.Fluid volume from neck drainage catheter and plasma albumin concentration were determined in 2 cases.Results: Fluid volume from neck drainage catheter rapidly reduced in 2 cases after using somatostatin and parenteral nutrition.1case was cured after conservative treatment.1 case was cured after re-operation combined with nutrition support.Conclusion: By using nutrition support,fluid volume from neck drainage catheter can be obviously reduced and serum albumin or nutritional state improved in chylous leakage patients after thyroid carcinoma operation.
