In this paper the investigation of using a new method-ABC-ELISA in assay of Autoimmune Thyroid Disease are presented. The sensitivity of ABC-ELISA is compared with that of standard ELISA; Its reliability is proven by the methods of detecting TSAb with FRTL-5. TRAb is detected by ABC-ELISA in 91% of untreated Graves'. TRAb is detected by Standard ELISA in 70% of untreated Graves'. The results of ABC-ELISA in 26 untreated Graves' are equal to that of the method of detecting TSAb with FRTL-5. Therefore, we consider that ABC-ELISA is a sensitive, reproducible, convenient method applicable to clinical practice.

Objective: To investigate the protective effect of adenosine on hearing in acute acoustic trauma and its modulatory action in the cochlea. Methods:Guinea pigs were exposed to 118 dB SPL white noise for 30 min. During the process of exposure, artificial perilymph or artificial perilymph containing 1 mmol/L adenosine was infused into the cochlea through perilymphatic perfusion. Thresholds of compound action potentials (CAP) evoked by click and tone burst were measured before and after noise exposure. Results: Immediately after exposure, the mean threshold shifts evoked by click of the control group and adenosine treated group were (40?6.68) dB and (20?5.70) dB respectively. The threshold shifts evoked by tone burst at 2 8 kHz in the control animals were 32 50 dB, while in the adenosine treated animals, 20 35 dB. There were significant differences between the 2 groups except that at 6 kHz. Two hours after exposure, there was an increase of 4 8 dB at all frequencies in the control group; no changes in the adenosine treated group were found. There were significant differences in threshold shifts between the 2 groups at all test frequencies. Conclusion: Adenosine has protective effect on temporary threshold shift in acute acoustic trauma in guinea pigs. [

Objective To determine the minimum alveolar concentration(MAC) of sevoflurane without body movement during laryngeal mask airway(LMA)intubation in premature infants less than 37 weeks of corrected gestational age undergoing total inhalation general anesthesia induction.Methods Twenty-one ASA Ⅰ or Ⅱ premature infants less than 37 weeks of corrected gestational age undergoing elective inhalation general anesthesia were enrolled in this study.At first,the general anesthesia induction was started by inhaling 6 ％ sevoflurane.After the premature infant lost consciousness,the end tidal sevoflurane concentration(ET-sev)was adjusted to the predetermined concentration and maintained stable for 15 min.After that,LMA was inserted.The up-anddown sequential allocation was used to determine MAC.The initial ETsev was 2 ％,which was increased or decreased by 1 gradient concentration in the next case according to the LMA insertion body movement response.The adjacent concentration gradient was 0.2％.The midpoint from th body movement response to non-body movement response was set as the balance point and the mean value of the concentrations of sevoflurane at all the balance points were calculated as MAC.Results The end tidal sevoflurane con centration without the body movement responses to LMA insertion was 1.71％.Conclusion The MAC of sevoflurane without the body movement responses to LMA insertion in premature infants less than 37 weeks of corrected gestational age is 1.71％,which is lower than that in the normal children and probably because imperfect central nervous system development in premature infants.

Objective: To investigate the biological behavior and prognosis factors of type B3 thymoma, and evaluate the efficacy of radiotherapy in patients with type B3 thymoma. Methods: A total of 188 consecutive patients with pathologically confirmed type B3 thymoma were treated in Shanghai Chest Hospital from January 2001 to December 2010. According to Masaoka stageing criteria, 35 (20%) were stage, 20 (11%) were stage, 78 (44%) were stage, and 44 (25%) were stage. Myasthenia gravis coexisted in 54 patients. Results: After a median follow-up of 49 months (7-135 months), the 5-year overall survival rate was 84% (100.0%, 89.0%, 86.1% and 59.8% of stages and respectively), and the 5-year progression-free survival rate was 65% (100.0%, 94.0%, 67.3%, and 33.0% of stages, and respectively).The reccurence rate was 22% and the metastatic rate was 7%. In the univariate analysis, tumor size, Masaoka stage, resection margin, radiotherapy and chemotherapy were significantly associated with 5-year overall survival and progression-free survival (P < 0.05). In the multivariate analysis, Masaoka stage, resection margin and radiotherapy were independent prognostic factors of 5-year progression-free survival (P < 0.05). Radiotherapy could improve the regional control rate and the overall survival of Masaoka stages ?-? patients. The intensity-modulated radiation therapy of pleure could probably improve the overall survival of recurrent patients. Conclusion: The major failure mode for type B3 thymoma is the recurrence of pleure. Radiotherapy can improve the regional control rate and the overall survival of the advanced patients. The intensity-modulated radiation therapy may be the best therapy for the postoperative recurrence of pleure. Copyright © 2013 by TUMOR.

Objective:To investigate the clinical features of patients with ankylosing spondylitis ( AS) and malignancies. Methods: In the study, 31 AS patients with malignancies in Peking University First Hospital from January 2006 to July 2014 were enrolled, and their clinical features were compared with AS patients without malignancies at the same time in the hospital. Then their general characteristics, clinical and imaging findings of AS, characteristics of malignancies and prognosis were retrospectively analyzed. Results:The 31 cases of AS with malignacies accounted for 11 . 8% of all AS patients admitted to the hos-pital in the same period. They comprised of 27 males (87%) and 4 females (13%) . Their mean ages at diagnosis of AS were 43 ± 17 years ( range:16-76 years) , and their mean ages at diagnosis of malig-nancy were 60 ± 12 years ( range:31-87 years) respectively. Malignancy was diagnosed after the estab-lishment of AS in 27 of our patients. Furthermore, imaging changes typical of AS were found in all the 31 patients at the diagnosis of AS, but the majority of them had never received any proper treatment for AS. The malignancies of 31 AS patients included bladder cancer (7 cases) , hematological malignancy (6 ca-ses), lung cancer (5 cases), renal cancer (5 cases), prostate cancer (2 cases), carcinoma of renal pelvis (2 cases) , breast cancer (2 cases) , gastric carcinoma (2 cases) , rectal cancer (2 cases) , neu-roendocrine carcinoma (2 cases) , colon carcinoma (1 case) , and esophagus cancer (1 case) . Conclu-sion:There is risk of malignancy in AS. Malignancy is not rare in patients with AS. Bladder cancer is the most common one followed by hematological malignancy. In consequence, close attention should be paied to the conditon of AS with malignancy in clinical practice.
