We describe a case of bilateral thyroid carcinoma in a 48-year-old woman. She was admitted to our hospital as a case of cervical nodular goiter. Multifocality of the thyroid nodules were evaluated by preoperative ultrasonography. The patient received bilateral thyroid lobe total resection and bilateral IV lymph node dissection. Medullary thyroid cancer was confirmed by intraoperative frozen pathology in the right lobe of thyroid gland and papillary thyroid microcarcinoma in the left lobe of thyroid gland. No tumor recurrence and metastasis were found after 3-months follow-up.

Objective To investigate the effect of Xing-Zhi-Yi-Nao (XZYN) particles on the expressions of Nogo and OMgp proteins in brain of rats after acute carbon monoxide (CO) poisoning.Methods A total of 120 Sprague-Dawley rats were randomly divided into normal group,CO poisoning group and XZYN particles treatment group (40 rats in each group).The rats in CO poisoning group and treatment group of acute CO poisoning were established by using an animal chamber,and then received hyperbaric oxygen therapy.Meanwhile,rats in treatment group were further given additional XZYN particles twice a day by gavage.At 1 day,1 week,1 month and 2 months after CO poisoning,the neurobehavioral score of rats was evaluated by a Morris water maze test and a shuttle box test,and the expressions of neurite outgrowth inhibitor (Nogo) and oligodendrocyte-myelin glycoprotein (OMgp) were investigated in rat brain tissue by immunohistochemistry staining and western blotting assay,respectively.Results Compared with those in normal control group((11.6±8.4)s,(41.8±4.4)%,(16.1±2.3)s,and (1.2±0.2)s),the escape latency in CO group was significantly prolonged ((14.1±6.1)s),and the T1/ T total was obviously decreased (23.6±2.4) %,the escape time ((26.3±3.8)s),the active escape latency ((2.3±0.3)s) were notably extended at 1 d (P<0.05).The cognitive dysfunction caused by CO poisoning was more obvious in the later stage of poisoning (from 1 week to 2 months,P<0.05).Compared with those in CO group,the escape latency was significantly shortened (from (3.5±0.6)s to (3.1±0.5)s),the T1/ T total was gradually increased (from (29.7±3.2)% to (36.7±3.2)%),the escape time (from (39.7±5.4)s to (18.1±2.0)s) and the active escape latency were obviously decreased (from (4.3±0.4)s to (2.1±0.2)s) in the later stage (>1 week) in Xing-Zhi-Yi-Nao treatment group (P<0.05).The expressions of Nogo and Omgp proteins in brain tissue in CO poisoning group were gradually increased as time went by.The increased expressions of Nogo and Omgp proteins were still observed at 1 month after CO poisoning.By contrast,XZYN particles could significantly improve cognitive function,reduce the expression of Nogo protein,and there was statistical difference compared with the poisoning group (P<0.05).However,the level of Omgp protein in XZYN treatment group was slightly lower than that in CO poisoning group,but there was no difference between the two groups (P>0.05).Conclusion The expression of Nogo and Omgp proteins may be associated with brain injury and demyelination in rats induced by CO poisoning.XZYN particles can down-regulate the expression of Nogo,and pave a way for the treatment of acute brain damage and delayed encephalopathy after CO poisoning.
