0.05). However, a significant higher percentage of CD3+CD25+ T cells was found in stable liver transplantation group as compared to healthy group ( P0.05). There was not found no regular change of serum cytokine s (IL-6, TN F-?) and adhesion molecules (ICAM-1, P-selectin) in 6 liver transplanted patien ts during post-operation from day 1 to day 30, indicating that was associated wi th the different status of patients before or after transplantation. CONCLUSIONS: Our data suggesting that increased levels of ICAM-1 and P-selectin, appears to participate in the processing of immunoregulation to transplanted livers, whereas elevated concentrations of IL-6 appear to be involv ed in the repair of the injury induced by TNF-? in allo-transplanted livers.

OBJECTIVE To investigate the deafness-related gene mutation frequency and hotspots in patients of Fuzhou city with non-syndromic hearing loss (NSHL). METHODS Peripheral blood samples were obtained from 88 cases of patients with hearing loss after clinical history inquiry and clinical examination. Their genomic DNA was extracted from peripheral blood by extraction kits to undergo polymerase chain reaction, traditional capillary electrophoresis sequencing and High-throughput sequencing so as to detect the mutations of deafness-related gene. RESULTS Among the 88 patients with NSHL, the gene mutation frequency was 34.09%.In the patients, 14 cases had mitochondrial 12 S rRNA mutations, six cases had GJB2 gene mutations and three cases had SLC26A4 mutations, two cases had MYO15A mutations, the other five cases had MYO7A, OTOF, TECTA, TMC1 and ILDR1 gene mutation respectively. CONCLUSION Among the 88 patients with NSHL, the most frequent mutation causing hereditary deadness was mutation in mitochondrial 12 S rRNA, followed by GJB2 and SLC26A4, The other genes such as MYO7A, OTOF, TECTA, TMC1 and ILDR1 gene were infrequent. The study could provide theoretical reference in genetic diagnosis, prevention and cure of hearing loss.

Objective To investigate the sonographic features of follicular variant of papillary thyroid carcinoma (FV-PTC) and to decrease misdiagnosis rate. Methods Thirty-one patients with 35 FV-PTCs and 66 patients with 75 conventional PTCs (C-PTCs) were enrolled in this study. The sonographic features were reviewed retrospectively between the two groups with universally accepted standards. Results The sonographic features of 35 FV-PTCs included irregular shapes (6/35), anteroposterior to transverse diameter ratio A/T > 1 (7/35), spiculated margins (25/35), marked hypoechogenicity (0/35), hypoechogenicity (18/35), isoechogenicity (16/35), no calcification (15/35), microcalcifications (11/35), macrocalcification (9/35), color Doppler lfow patternⅠ(20/35), color Doppler lfow patternⅡ(10/35), color Doppler lfow patternⅢ(5/35). Irregular shapes, A/T>1, spiculated margins, marked hypoechogenicity, microcalciifcations, and color type Ⅱ were rarer in FV-PTCs than in C-PTCs, while isoechogenicity, no calciifcation, macrocalciifcation, and color type Ⅲwere more frequent in FV-PTCs than in C-PTCs. The differences of the above features were statistically significant [χ2=4.276, P=0.039; χ2=8.125, P=0.004; P=0.009 (Fisher′ s exact test); χ2=8.548, P=0.003;χ2=4.898, P=0.027,χ2=7.796, P=0.005;χ2=5.462, P=0.019;P=0.001 (Fisher′s exact test)] . During the preoperative ultrasonography, 20 of 35 FV-PTCs were diagnosed as malignancy, and others were misdiagnosed as benign nodules (misdiagnosis rate was 43%). The lymphatic metastasis rate of FV-PTCs was 29%(9/31), significantly lower than C-PTCs [62%(41/66),χ2=9.246, P=0.002]. In terms of the sonographic features of metastatic lymph nodes, there was no marked difference between FV-PTCs and C-PTCs. Conclusions Some FV-PTCs are lack of malignant features, and tend to be misdiagnosed frequently when coexisting with benign thyroid nodules. Observing the echogenicity, color lfow characteristics and other features of each thyroid nodule and cervical lymph node with multiple views may decrease the misdiagnosis rate.
