Objective To detect the expression and function of ZNRF3 in different kinds of thyroid cancer tissues and cells.Methods Immunohistochemistry was used to detect the expressions of ZNRF3 protein in 35 cases of papillary thyroid carcinoma and 10 cases of poorly differentiated thyroid carcinoma.The expressions of ZNRF3 gene in TPC-1 and 8505C were detected by RT-PCR,and the cell lines were derived from papillary thyroid carcinoma and poorly differentiated thyroid carcinoma respectively.After silenced ZNRF3 gene expression with lentivirus,the proliferation ability of TPC-1 cells were detected with CCK-8,the invasion and metastasis ability of TPC-1 cells were detected with Transwell.Results According to results of immunohistochemistry and RT-PCR,the expressions of ZNRF3 in papillary thyroid carcinoma cells and tissues were higher than those in poorly differentiated thyroid carcinoma cells and tissues,the differences were statistically significant (4.83±0.44 vs.3.13 ±0.59,t =2.20,P ＜0.05;1.01±0.06 vs.0.21±0.04,t =11.80,P＜0.01).After ZNRF3 geng silencing,according to the results of CCK8,the proliferation ability of TPC-1 cells was significantly enhanced in 72 h,the difference was statistically significant (0.96 ± 0.10 vs.0.64 ± 0.05,t =3.19,P ＜ 0.05);and according to the results of Transwell,the TPC-1 cell's invasion (0.12 ± 0.01 vs.0.09 ±0.00,t =5.48,P＜0.01) and migration (0.22 ±-0.01 vs.0.17 ±0.01,t =4.58,P ＜0.05) also increased,the differences were statistically significant.Conclusion The expression of ZNRF3 in papillary thyroid carcinoma is higher than that in poorly differentiated thyroid cancer.ZNRF3 is tumor suppressor gene in the thyroid tumors.

Multilocus sequence typing (MLST) is a molecular genotyping method based on nucleotide sequencing. The procedure of this method characterizes isolates of bacterial species using the DNA sequencing of multiple housekeeping genes(usually seven). For each housekeeping gene, the different sequences present within a bacterial species are assigned as distinct alleles.For each isolate, the alleles at each of the loci define the allelic profile or sequence type (ST). MLST has the advantages of being robust (based on genetic data) and electronically portable to generate data that allow rapid and global comparisons between different laboratories. In this paper, the principle, method, data analysis, application, advantages and flaws of MLST are introduced.

AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film.
METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively.
RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative.
CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.

This study is to investigate the protective effect of rosiglitazone (RSG) against learning and memory impairment of APP/PS1/tau transgenic mice. AD mice model was replicated by using 6-month APP/PS1/tau transgenic mice. The learning and memory ability of mice was evaluated by Morris water maze and Western blotting assays was applied to measure the phosphorylation and O-glycosylation of Tau and neurofilaments (NFs) protein. The results demonstrated that RSG could reverse the learning and memory deficits of 3 x Tg mice significantly. It was also found that RSG could suppress the hyperphosphorylation of Tau and NFs protein levels and increase the glycosylation expression of Tau and NFs proteins in 3 x Tg mice brain. Together, RSG ameliorates cognitive impairments of 3 x Tg mice via the alleviation of the hyperphosphorylated Tau and NFs proteins burden in the brain.

Objective To evaluate 18F-fluorodeoxyglucose (FDG) PET/CT in detecting occult malignancy in patients with suspected paraneoplastic neurological syndrome (PNS).Methods Twenty consecutive patients who underwent PET/CT scanning with the indication of suspected PNS were retrospectively reviewed.The gold standard of PNS was either cytology or clinical follow-up, and the final diagnosis was compared with PET/CT findings.Results Of the 20 patients, six were PNS.PET/CT detected nine cases.Six were true positive and three were false positive.The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PET/CT were 100% (6/6), 78.57% (11/14), 85.00% (17/20),66.7% (6/9) and 100.00% ( 11/11 ) respectively.The treatment plan was modified based on the PET/CT results in 4 patients.Conclusions 18F-FDG PET/CT may play a role in detecting the underlying malignancy of PNS.It is also valuable in staging of the malignancy thus providing information for therapy decision making.

Objective To explore possible associations between host polymorphism of HLA classⅡgenotypes and advanced hepatosplenic schistosomiasis japonica.Methods 45 advanced schistosomiasis patients(experimental group) and 44 age,and sex,matched patients with chronic schistosomiasis(control group) from the same area were investigated for their HLA class II gene DRB genotypes by genotyping the alleles using microarray DNA chip.The correlation of allele frequencies to advanced hepatosplenic schistosomiasis was compared for the two groups.Results HLA,DRB1*04x exhibited markedly higher frequency in advanced patients than that in control group(P

Objective To review the surgical managements of patients with traumatic false aneu- rysms in the extremities.Methods From January 1990 to April 2006,17 patients with traumatic false aneurysms in the extremities were admitted into our hospital.Fourteen patients were treated by vascular repair including vascular repair in seven cases,end to end anastomosis in one,synthetic grafting in one, autogenous vein grafting in one,and direct ligation in four.Three patients were treated nonoperatively, but with local compressive dressing.Results There were no deaths or gangrenes in all cases.The clinical manifestations vanished after the treatment.The mean follow-up period was 13.2 months.The function of the injured extremities recovered satisfactorily.Conclusion Different types of traumatic false aneurysms should be managed by different therapeutic procedures after the diagnoses is made.
