Objective To determine the predictive factors for lateral lymph node metastasis (LNM) in papillary thyroid microcarcinoma (PTMC). Methods From January 2002 to December 2009,77 patients with PTMC were treated by modified radical neck dissection. We analyzed the association between lateral LNM and clinical factors, US features, hematological parameters and pathologic features of PTMC. Results The rate of lateral LNM was 39% in 77 PTMCs (30/77). We found a statistically significant association between lateral LNM and age, pathologic features ( extrathyroid invasion and central LNM), higher platelet counts and US features of PTMC (upper pole location,contacting area of the tumor with the capsule of throid gland > 25% of the perimeter of the tumor) in univariate analysis (statistic values were 2.425,6. 392,12. 584,2. 143,8.755 and 6.89,respectively,Ps< 0.05). Age,pathologic features (central LNM) and US features of PTMC (upper pole location) were found to be independent predictive factors for lateral LNM in multivariate analysis ( OR and 95%C/ was 0.942(0.889 -0.998) ,4. 396( 1. 241 - 15. 573) and 4.436( 1. 194 - 16. 482) ,P was 0. 042, 0.022 and 0.026,respectively). Conclusion In patients with PTMC,independent factors in predicting lateral LNM were age, US features of PTMC ( upper pole location) and pathologic features (central LNM ). These patients should receive relatively aggressive initial treatments and vigilant follow-up.

Objective To report a Chinese pedigree with benign familial chronic pemphigus (BFCP),and to screen mutations of ATP2C 1 gene in this family.Methods A 39-year-old male patient with BFCP andhis family members underwent a clinical investigation.Blood samples were collected from all the members in this family and from 50 unrelated healthy controls.Genomic DNA was extracted from the blood samples,and PCR was performed to amplify all the 28 exons and flanking sequences of the ATP2C1 gene followed by DNA direct sequencing.The resulted DNA sequences were compared with the reported sequences of APT2C1 gene in Genbank (Number:NM_014382.2 and NC_000003.9).Results There were 24 family members in the four-generation pedigree,with 8 members affected by BFCP.A single-nucleotide substitution,c(1696C→T),in exon 17 of the ATP2C1 gene was identified in all of the members with BFCP,but not in unaffected third-or second-generation members or unrelated healthy controls.This substitution was also found in 1 out of 4 family members of fourth-generation.Conclusions The nonsense mutation c(1696C→T) in the ATP2C1 gene,is likely to be responsible for BFCP in this Chinese four-generation pedigree.The underage family member of fourth-generation who carried the mutation c(1696C→T) but had no clinical symptoms of BFCP,should be closely followed.

Objective To investigate the relationship between the expression of MIF mRNA and TNF-α in the lung tissue of rats with acute necrotizing pancreatitis (ANP) and explore their mechanism of action in acute lung injury during the course of ANP. Methods A total of 40 Sprague-Dawley rats were randomly divided into four groups (n = 10 in each group) : the sham operation (SO) group, ANP 3h group, 6h group, 12h group. The model of ANP was induced by retrograde injection of 5% sodium tanrocholate (0. 1 ml/100 g) into the biliary and pancreatic duct. The level of serum amylase was determined;pancreatic and lung tissues were harvested for pathological examination, and wet/dry weight ratios were estimated. Intrapulmonary expression of MIF mRNA was assayed by semi-quantitative RT-PCR. TNF-α in pulmonary homogenate was measured by immunoradiometric assay. Results Serum amylase, wet/dry weight ratios of pancreatic and lung tissues all significantly increased, and pathological injuries aggravated with time in ANP groups. Levels of TNF-α in ANP 3h, 6h, 12h group were (0.69 ± 0. 107) ng/ml, (1.64 ± 0. 10) ng/ml and (0.92 ± 0.11) ng/ml, and expression of MIF mRNA were 1.97±0.09, 2.55±0.23, 3.29±0.26, which were significantly higher than those in control group [(0. 19±0.06)ng/ml, 1.21±0.34, P<0.01]. lntrapulmonary expression of MIF mRNA was positively associated with lung pathological injuries, wet/dry weight ratio, and TNF-α(r = 0. 637, r = 0.684, r = 0.858, P < 0.01). Intrapulmonary levels of TNF-α was positively associated with lung pathological injuries, wet/dry weight ratio (r=0.540, r=0.421, P<0.01). Conclusions MIF mRNA was over- expressed and level of TNF-α was significantly increased in pulmonary tissue in rats with ANP, and this may be one of the mechanisms in the pathogenesis of lung injury in ANP.
