[Objective]To analyze the clinical and biological characteristics of suspected malignant thyroid nodules associated with Hashimoto thyroiditis .To summarize different characteristics of benign and malignant nodules,diagnosis and treatment of suspected malignant nodules associated with Hashimoto's thy-roiditis. [Methods]Surgical y and pathological y confirmed, 58 cases of suspected malignant thyroid nodules associated with Hashimoto's thyroiditis were retro-spectively analyzed with clinical and pathological data. The differences of gender, age, number of nodules, calcification, and thyroid hormone and thyroid an-tibodies levels between malignant and benign nodules were compared from January 2009 to December 2011 .[Results] The average age of malignant thyroid nodules coexisting with HT group was significantly lower than that of benign nodules coexisting with HT group( P<0.05). The proportion of nodular calcifi-cation in malignant thyroid nodules coexisting with HT group was significantly higher than that in benign nodules coexisting with HT group( P<0.05). Pre-operative TSH and anti-TG levels in malignant thyroid nodules coexisting with HT group were significantly higher than that in benign nodules coexisting with HT group. Preoperative FT3, FT4, anti-TPO levels, sex ratio and number of lesions between the two groups were not statistical y significant. [Conclu-sions] The key point of preoperative diagnosis:patients of malignant thyroid nodules coexisting with HT are associated with youth, calcified nodules, elevated serum TSH and anti-TG levels.

To illustrate the location of HSP-70 (heat\|shock protein\|70)correlative response in acute stage between middle and inner ear when mammalian middle ear infected by bacteria, and investigate the possibility to cause autoimmune inner ear injure by HSP-70 that induced by otitis media. An animal model of acute otitis media was established by inoculating Klebsiella pneumoniae (K.p) into middle ear of guinea pigs. Animals were sacrificed 1,3,5 and 7days after inoculation.Investigation of the locations of HSP-70 in middle ear mucosa and cochlea structures were detected by immunocytochemical technique .The results showed that light stain of HSP-70 existed in the superficial epithelium cells of normal mucosa and cochlea structures such as stria vascularis, spiral ligament and Corti′s organ.Heavy stain appeared in the same sites in the infected ears . No different positive sites was observed in all animals.Our findings suggested that HSP-70 were expressed in middle ear mucosa and inner ear structures during acute middle ear infective stage.The HSP-70 provide a material base for causing autoimmune inner ear injure during middle ear bacteria infection.

Objective To explore the accuracy and clinical application of Pyrosequencing for detection of drug resistant relevant mutation in the polymerase gene of Hepatitis B virus (HBV).Methods Compared with Sanger sequencing,the accuracy and sensitivity of Pyrosequencing were assessed.Pyrosequencing was used to determine the serum of 1164 patients with chronic Hepatitis B and its results were analyzed.Results The sensitivity of Pyrosequencing was 1 × 103 KIU/L,the same as Sanger sequencing.But Pyrosequencing was more stable and specific than Sanger sequencing to detect low rate of mutation with over 10％ mutation.The mutations couldn't be detected in 248 patients with chronic Hepatitis B,but positive results occurred in 919 patients,among them,61.5 ％ without mutation,38.5 ％ with mutation (including 47.5％ of the single locus mutation and 52.5％ of the combined mutation).Other sites had different degree of mutations except the sites of rtI169T and rtA194T; the main mutation sites in patients with chronic Hepatitis B were rtM204V/I (32.1％),rtL180M (19.8％),rtA181V/T (6.7％) and rtN236T (5.3％),in which fractional mutation had high ratio in the sites of rtA181V/T (6.7％) and rtN236T (5.3％).Conclusions Pyrosequencing has good sensitivity,specificity and accuracy and can early detect the drug resistant relevant mutation in the polymerase gene of HBV,which is suitable for monitoring patients with chronic Hepatitis B for the treatment of nucleoside analogues (acid).The different sites and frequencies of mutations may be associated with different habits of doctors for using different anti-HBV drugs.
