Objective To evaluate a combination therapy for huge tumors in the buttocks.Methods A total of 11 patients from our hospital were collected,among them 5 cases were of hemangioma,4 cases of neurofibroma,2 cases of soft tissue sarcoma.Before definite surgical resection all cases received tumor embolization with silk thread and gelatin-sponge article using Seldinger's technic.Subsequently,all patients underwent a successful tumor resection. Results Superselective embolization for all the cases'feeding arteries resulted in recession of the tumors and relatively well-demarcated margins,and all the lumps became softer.and the local pain was alleviated.Surgical resection could be radical with avoidance of fatal intraoperative hemorrhage.The 5 cases of hemangioma had a average operative bleeding of 450 ml,4 cases of neurofibroma had 420 ml,2 cases of soft tissue sarcoma had 150 ml.No patients needed intraoperative and postoperative blood transfusion.The operation time was about 2-3 hours,the normal tissues were preserved and the contour and function of the diseased limbs were very good.One case had a delayed incision healing,and the others had a healing by the first intention.There was no recurrence and other complications (like deep venous thrombosis)during a follow-up period of 4-8 months. Conclusions Surgical resection combined with interventional embolism for the treatment of huge tumors in the buttocks can reduce the risk of bleeding effectively during operation.It can improve the success rate of operation leading to satisfactory results.

OBJECTIVETo investigate the level of tumor necrosis factor alpha (TNF-alpha) and epidermal growth factor (EGF) in patients with medicament-like dermatitis by trichloroethylene (DMLT).

METHODSUsing radioimmunoassay methods, serum TNF-alpha, EGF were measured in 39 patients with DMLT and in 20 controls.

RESULTSThe levels of serum TNF-alpha, EGF in patients with DMLT [(0.278 +/- 0.092) ng/L, (6.71 +/- 2.28) microg/L, respectively] were significantly higher than those of the controls [(0.128 +/- 0.029) ng/L, (4.31 +/- 1.13) microg/L respectively, P<0.05, P<0.01].

CONCLUSIONThe increased levels of serum TNF-alpha, EGF in patients with DMLT may be related to the following causes: (1) Trichloroethylene and its metabolite may irritate the macrophagocyte and monocyte in human body to release TNF-alpha into blood stream; (2) Severe damage of epithelial tissue in patients with DMLT may promote more EGF synthesis to accelerate the regeneration and repair of epithelial tissue.

OBJECTIVETo study the best observation time for drug administration and withdrawal in the treatment of children with transient congenital hypothyroidism,seeking an objective basis for the safe drug withdrawal.

METHODSLevothyroxine was prescribed for 1 144 children diagnosed with congenital hypothyroidism (CH) and according to the results levothyroxine was adjusted to a maintenance dosage. Examinations were performed periodically including physical and mental development, thyroid ultrasonography,and blood levels of T3, T4, TSH. For the patients with a small maintenance dosage of levothyroxine (15.0 - 16.6 g/d) and all the examinations normal, levothyroxine was withdrawn at 2 - 3 years, and the children were followed up and reexamined after 1 month, 2 months, and 10 months, respectively. Permanent drug withdrawal was determined for children with all the examinations normal. Once abnormal TSH occurred, levothyroxine was prescribed again, and followed up continuously.

RESULTLevothyroxine was withdrawn from 157 children. During the follow up, for 15 children (9.55%) levothyroxine were prescribed continuously, and for 142 children permanent drug withdrawal (confirmed with transient CH) was determined. Abnormal TSH of various degrees was detected in 48 cases: 25.48 % (40/157),4.46 % (7/157), and 0.64 % (1/157) were detected at 1, 2 and 10 months after drug withdrawal, respectively. In 15 children levothyroxine was prescribed again for the remarkably high TSH, and the other 33 with mildly abnormal TSH finished the treatment since TSH normalized during follow-up.

CONCLUSIONAfter 2 - 3 years of regular treatment, levothyroxine can be withdrawn from children with normal T3, T4, TSH, physical and mental development, and thyroid function. The best observation time for drug withdrawal should be 2 - 3 months. If T3, T4 and TSH levels are in the normal range, drug can be withdrawn safely. Once abnormal results were detected during follow-up, levothyroxine should be administrated continuously.

OBJECTIVETo study the effects of noise on bioactivity of norepinephrine (NE) and cardiovascular system.

METHODSA total of 130 workers exposed to the occupational noise in one enterprise were selected as noise exposure group, and 134 workers not exposed to the occupational noise and other poisons served as control group. Fasting venous blood was drawn to determine the content of NE in peripheral blood with ELISA. According to Occupational Health Surveillance Manage regulations, the occupational noise exposures crowd was examined.

RESULTSThe average of NE in exposure group was (0.1387 +/- 0.099) ng/ml, and (0.1019 +/- 0.080) ng/ml in control group. There was significant difference in NE between exposure and control group. There was significant difference in the detection rate of BP, HR and ECG between exposure and control group.

CONCLUSIONThe occupation noise can increase the NE in peripheral blood, and maybe affects the cardiovascular system in this way.

U251 cell is a sensitive cell line to serum, which stops at G0 phase of cell cycle in no-serum medium, and recovers growth when the serum is added into no-serum medium. The cell can express corresponding proteins in different phase of cell cycle. Therefore it is very signification for the study of cell cycle regulation mechanism that explores these proteins. In this paper, the mouse antibody phage display library was added into the bottle in which the serum starvation U251 cells had been cultured, and the special antibody phages were absorbed. Then the absorbed antibody phages were amplified by adding E. coli TG1 and helper phage M13K07. Amplified antibody phages were added into bottle in which the serum cultured cell after serum starvation (follow named as serum recovered cells) were incubated, so that the cell absorbed the no-special antibody phages for the serum starvation cell and the special antibody phages were in supernatant. The remaining no-special antibody phages in the supernatant were discarded by repeating above program 3-4 times. The pure special antibody phages were gotten, and amplified by adding the host cell E. coli TG1 and helper phage M13K07. Then the host bacterium infected special antibody phage was spread on the plate medium with ampicillin, and the monoclonal antibody phages were gotten. Using same as above program, the monoclonal antibody phages absorbed specially for serum recovered U251 cells were obtained when the serum recovered cells instead of serum starvation cells and serum starvation cells instead of serum recovered cells. In this study, ninety-six positive monoclonal antibody phages that absorbed specially the serum starvation cells and eighty-two positive monoclonal antibody phages that absorbed specially the serum recovered cells were obtained. By using cell immunochemistry assay, two special signification antibodies were obtained. one (No.11) was the strong response in serum starvation cells, the other (No.2) was the strong response in serum recovered cells. The antibody No.2 had the distinctive response to the serum recovered cells in different incubation time (15min, 30min, 1h, 2h, 4h, 8h, 12h and 48h) after serum starvation. The results showed that No.2 antibody would be useful to research the factors of cell cycle regulation and apply to tumor diagnosis.
