Our department treated one case of neonatal congenital cyst of tongue in March 23, 2015. The clinical manifestation of the case is mainly laryngeal stridor after birth 10d, and when infants were associated with progressive dysphagia. Electrolaryngoscope examination showed the goitre look like the cyst of tongue. Laryngeal CT scanning showed tongue lesions, consider the possibility of large cyst. Bilateral thyroid gland showed good, and no obvious abnormality was found in the cervical ultrasonography. The children was transferred to the ear-nose-throat department for excision of cyst of tongue by low-temperature plasma knife, and postoperative pathology confirmed the diagnosis of cyst of tongue.

The α chain of hemoglobin of 615 mouse was isolated and purified on CM-Celullose-23 colomn chromatography. The N-terminal amino acid of the α chain was valine determined with DABITC/PITC method.The amino acid composition was determined and it was different from the parent(C57BL)in literature on the number of leucine residue,histine residue and valine residue.An undissoluble ‘core’ and dissoluble peptides were found when the α chain of 615 mouse was hydrolysised by trypsin and it was found that the eighth amino acid residue from N-terminal of one particular peptide fragment mutated from valine (C57BL) to leucine.

Objective:To construct pGEX-3X/hTSHa Escherichia coli(E.coli)expression system and prepare purified recombinant GST-recombinant human thyroid stimulating hormone(rhTSH)α protein.Methods:The complete coding sequence of hTSHα was obtained by RT-PCR with total RNA extracted from fresh chorial tissue as the template,and thereafter cloned into expression vector pGEX-3X by EcoRl and BamHI digestion.The recombinant plasmid was transformed into E.coli Mach1-T1 and then induced expression by WrG.The GST-rhTSHα fusion protein was identified by SDS-PAGE and its antigenicity was verified by a modified competitive ELISA.Results:A specific protein band of 36 ku,in accordance with predicted molecular weight,could be visualized in SDS-PAGE.As the result of ELISA,the recombinant GST-hTSHα protein can inhibit the intact TSH molecular binding with anti-TSHα antibody in a dose dependent manner.Conclusion:The cDNA of hTSHα was cloned and the recombinant expression vector pGEX-3X/hTSHα was constructed successfully.The recombinant GST-rhTSHα protein could be highly expressed in E.coli Machl-T1 and was approved of possessing antigenicity.

Objective:To investigate the effects of Liuweidihuang pill on the insulin levels in sera and pancreatic islets from spontaneous mouse models of human type 2 diabetes administrated with different doses .Methods:The 6-8 week-old KK-Ay mice were randomly divided into three groups including no drug control group ,low-dose group and high-dose group,in addition C57BL/6J mice were used as a genetic control group .All the animals were given with different dose Liuweidihuang pill solutions or sterile distilled water by intragastrical administration for fifteen weeks .The fasting blood glucose ,body mass and food consumption were measured weekly .The serum insulin levels were surveyed by ELISA .And the insulin levels in the pancreas islets were detected by immunofluorescence and immunohistochemistry .Results:Decreased fasting blood glucose ,controlled body mass and food consumption ,and lower levels of insulin in the sera and pancreas islets were confirmed from the KK-Ay mice administered with Liuweidihuang pill .Furthermore,the low dose program exhibits a stronger effect .Conclusion:Liuweidihuang pill has exhibited relatively therapeutic effects in the spontaneous type 2 diabetes mice including controls of hyperglycemia and body mass and relieving insulin resistance .In addition , the low-dose regimen showed even better treatment in controlling insulin levels in the sera and pancreas islets .
