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 observe leptin level before and after rosiglitazone administration and to explore the possible mechanism of rosiglitazone's improving insulin sensitivity.Methods A total of 30 patients newly diagnosed with type 2 diabetes were separated into three groups at random,and treated with rosiglitazone(4mg/d),metform(750mg/d) and gliclazide(160mg/d),respectively.Serum leptin,insulin and GHbA1c were measured after 12 weeks.Results After 12 weeks' treatment,the fasting glucose and GHbA1c in each group declined sharply,while free insulin did not change.The leptin level in rosiglitazone group decreased and insulin sensitivity was improved after administration,but there was no change in metformin and sulfonylureas groups.Conclusion Leptin may play a role in rosiglitazone's mediating the insulin-sensitizing effects.

OBJECTIVE: To investigate the possible stimulating mechanism of Huoxue Bushen Mixture (HXBSM), a traditional Chinese compound medicine, on hair growth of mice via measuring the variance of skin blood vessel neogenesis and vascular endothelial growth factor (VEGF) expression in the hair follicle. METHODS: Hot rosin and paraffin mixture depilation were used to induce C57BL/6 mice hair follicle to enter from telogen into anagen. Ninety C57BL/6 mice were divided into 3 groups randomly: HXBSM group, Yangxue Shengfa Capsule (YXSFC, another traditional Chinese compound medicine) group and untreated group. The mice were fed with corresponding drugs after modeling. The hair growth of the mice was observed every day. Every ten mice out of each group were executed respectively at day 4, 11 and day 17. Skin blood vessel neogenesis was counted through pathological section and VEGF expression in the hair follicle was measured via immunohistochemical method. RESULTS: The number of local blood vessel neogenisis in the HXBSM group observed was larger than that in the untreated group at day 4 (P<0.05); and evidently larger than that in the YXSFC group and the untreated group at day 11 (P<0.05). The expression of VEGF in the hair follicle was distinctively higher than that in the YXSFC group and the untreated group at day 11 and day 17 (P<0.05). CONCLUSION: HXBSM up-regulates VEGF expression to accelerate blood vessel neogenesis and hair growth.

Objective:To study the antibacterial properties of pure titanium treated with benzalkonium chloride solution.Meth-ods:10 mm ×10 mm ×1 mm titanium specimens were processed by the benzalkonium chloride solution at 1%,0.5% and 0.1%respectively followed by treatment in the cultured bacterial suspension,and then the antibacterial properties of the titanium plates were examined.Additionally,the thermal cycling test was carried out for the 1% benzalkonium chloride-treated titanium plates, and subsequently put the plates into cultured bacterial suspension,the duration of antibacterial properties was observed.Results:0.5% and 1% benzalkonium chloride solution-treated titanium plates significantly inhibited the growth of candida albicans(P <0. 05),1% solution was more effective than 0.5% solution.After 1 000 and 2 500 thermal cycling,the pure titanium still retained the antibacterial ability,but the plates treated by 5 000 cycling showed no antibacterial effect.Conclusion:A certain concentration of benzalkonium chloride can make the pure titanium obtain antibacterial properties.The treated plates may maintain the antibacte-rial properties for a minimum of 3 months.
