Objective Using hypothyroid,hyperthyroid and normol control rats model,we investigated mRNA expression of the nerve-growth-factor and its receptor TrkA in hippocampus and parietal cortex at 14,21,28days of ages,to offer a possible neurobiological explanation about mechanism of thyroid hormone modulating NGF and its receptor TrkA.Methods For hypothyroid group,rats were reared with 0.02% methimazol water from 5~6 day of gestation to the day when they were sacrificed;for hyperthyroid group,rats were daily intraperitoneal injected of 0.4?g/g body weight tiiodothyronin from beginning of delivery;for normal control rats were reared a normol diet and water.NGF mRNA and TrkAmRNA were measured by in site hybridization.Results The peak of mRNA expression of NGF and TrkA is at P21and P28 respectively,.The mRNA expression of NGF and TrkA in hypothyroid rats was significantly lower than that in age-matched euthyroid at P14,P21,P28(P

Objective Changes of thyroid stimulating antibody(TSAb) and thyroid stimulating blocking antibody(TSBAb) in the treatment of anti-thyroid drugs(ATDs), and the effect of ATDs combining with levothyrocine(LT4) on TSAb and TSBAb were analyzed. Methods Using recombinant Trxfus. TSHRn protein and Trxfus. TSHRc protein as antigens, and TSH receptor antibody(TRAb)-N(TSAb binding hot spots), TRAb-C(TSBAb binding hot spots)in the serum of thyroid disease patients were measured with ELISA. The changes of TRAb-N, TRAb-C over 36 months in 117 TRAb-N positive Graves′ patients with hyperthyroidism were analyzed retrospectively. In the course of treatment, 41 cases as A group with ATDs and LT4 treatment, 76 cases as B group with only ATDs, The changes of TRAb-N and TRAb-C were observed in the two groups. Results (1)According to the change of TRAb-N, 117 TRAb-N positive Graves′ patients with hyperthyroidism were different. In group Ⅰ, 10 patients continued to have persistently positive TSAb and continued to have hyperthyroidism, remission rate 0%. In group Ⅱ, 17 patients showed complicated TRAb-N changes, 12 of 17 patients got relapse, 5 of 17 patients got remission, remission rate 29.4%. And in group Ⅲ, with TRAb-N dropping gradually, 15 of 89 patients got relapse, 74 of the 89 patients got remission, remission rate 83.1%. Three groups were significantly different with x2 test(P<0.01). One of the 117 TRAb-N positive Graves′ patients with hyperthyroidism developed TRAb-C positive hypothyroidism. (2)According to combining with and without LT4 during the treatment of ATDs,the patients were divided into 2 groups(Group A: ATDs combined with LT4; Group B: only ATDs). These 2 groups were significantly different in TRAb-N at baseline and 3 months(P<0.01), TRAb-C between two groups were not significantly different in all times(P>0.05). Conclusion TSAb and TSBAb can be used to document TRAb-function, which is significant for us to predict the changes of thyroid function. During ATDs treatment, the temporary early low-dose application of LT4 did not significantly affect TSAb and TSBAb.

Objective To select and express a human thyrotrophin receptor antibody (TRAb) Fab fragment from phage antibody library constructed with phage display technology. Methods With immobilized antigen, the reconstructed humanized TRAb Fab library was enriched by five rounds panning (adsorption-elution-amplification). The TSAb Fab and TBAb Fab fragment were selected by coated fusion proteins of hTSHRn and hTSHRc. The positive clones were identified and selected by Phage-ELISA. TRAb positive clones were identified by PCR and double restriction enzyme digestion. The soluble TRAb (TSAb, TBAb) Fab fragments were expressed. TRAb (TSAb, TBAb) Fab fragments were identified by Western blotting assay. The DNA fragment was sequenced from the positive clones. Results Following five rounds of biopanning, TRAb (TSAb,TBAb) Fab phage antibody was screened. The enrichment effect reached to 77 times and 94 times. The soluble TRAb (TSAb,TBAb) Fab antibodies were expressed from positive clones and identified by phage ELISA. Western blotting analysis showed that the phage displaying Fab had significant binding activity with antigens. These sequence analysis showed that all of the heavy chain Fd gene and light chain gene were derived from human immunoglobulin variable region. The light chain variable region of the monoclonal 48 was homologous to the immunoglobulin light chain Vλ homology of 94.4%, and the heavy chain variable region of the monoclonal 48 was homologous to the immunoglobulin heavy Fd chain VH4 homology of 88.9%. The light chain variable region of the monoclonal 56 was homologous to the immunoglobulin light chain Vλ homology of 95.6%, and the heavy chain variable region of the monoclonal 56 was homologous to the immunoglobulin heavy Fd chain VH3 homology of 84.6%. Conclusion We have successfully selected TRAb (TSAb, TBAb) Fab fragment from a human phage display immune antibody library.

Objective To compare the effect of electrode positions o n multifocal visual evoked potential(mf-VEP). Methods Ten healt hy individuals were tested with RETIscan multifocal VEP system 3.20, each indiv idual was tested with four electrode positions: the active and reference electro de were placed 2.0 cm above and below the inion in Ch1;3.0 cm above and 4.5 cm below the inion in Ch2;2.0 cm on both right and left side of the inion in C h3 and 4.0 cm on both right and left side of the inion in Ch4. The summed ampli tudes of hemifield mf-VEP were analyzed and compared according to different ele ctrode positions. Results The difference among summed amplitud es of the upper or lower hemifield mf-VEP recorded with Ch1、Ch2、Ch3 and Ch4 w as statistically significant;and the difference between Ch2 and the other chann els was statistically significant too. The difference among summed amplitudes of the horizontal sites whose amplitudes were small when recorded with Ch2 and sum med amplitudes of the corresponding sites recorded with Ch3 and Ch4 were statist ically significant;and the difference between Ch4 and the other channels was st atistically significant too. Conclusions compared to Ch1、Ch3 and Ch4, Ch2 can make a better recording of mf-VEP. As for some sites, especi ally those along horizontal line, horizontal electrodes could improve the amplit udes of mf-VEP recorded with vertical electrodes,and Ch4 could do better to im prove the mf-VEP recorded with Ch2 than Ch3.

Objective To inverstigate the efficiency and safety of transcatheter uterine artery embolization (TUAE) as well as the pathological changes and it′s significance after embolization. Methods 44 cases of uterine fibroids were treated by TUAE using lipiodol pingyangmycin emulsion (LPE) and Gelfoam sponge paeticles. Seven of 44 cases underwent hysterectomy or myomectomy from 1 to 6 weeks after TUAE.The specimens were studied to observe pathological changes of fibroids and myometrium. 37 of 44 patients were followed up for 1 to 6 months to observe the changes of fibroid size and uterine volume. The changes of ovarian function and myometrium after TUAE were found out by observation on mensis, test of ovarian hormone, premenstrual diagnostic curettage and pathology of the resected specimens. Results Total improvement of symptams occurred in 91.9%(34/37), including control of menorrhagia in 91.4%(32/35), disappearance of lumbago and lower abdominal pain in 85 3%(29/34),relief of freguency and urgency of micturition in 50.0%(7/14). Average decrease of fibroid and uterine volume at 6 months after TUAE was 61.3% and 50.6% respectively. No amenorrhea happened. Premenstrual diagnostic curettage showed secretory endomtrium. There was no significant difference in ovarian hormon level befor and after embolization. Pathological study showed that lipiodol was found to deposit in fibroids and was not seen in myometrium. Spotty necrosis 2 weeks occurred in fibroid and extensive patchy necrosis 3 weeks after embolization. The necrotic area became larger with elapse of time postoperative. Necrosis was not seen in myometrium. Conclusion TUAE is a new ,and effective procedure for uterine fibroid and LPE as an embolizing agent is safe without damage on myometrium.

Objective To investigate the effect of flurbiprofen administration time on inflammatory factors in patients with acute suppurative appendicitis after laparoscopic resection. Methods 60 patients with acute suppurative appendicitis resection treated in our hospital from January 2015 to March 2017 were divided into two groups according to the different administration time. The control group received flurbiprofen at the time of operation, and the observation group received flurbiprofen before operation induction; The changes of the indexes of operation and inflammatory factors before and after the operation were compared between the two groups. Results There were no significant differences between the two groups in each operation index; The level of inflammatory factors in the observation group was better than that in the control group 24 hours after the operation, the difference was statistically significant (P<0.05). Conclusion The effect of flurbiprofen is significant before the induction of anesthesia, and the control effect of inflammatory factors is good after the operation, and the time will not affect the postoperative analgesia.
