The aim of this study was to investigate the expression of Tspan-1, Jab1 and p27 in human hepatocellular carcinoma (HCC) and their clinicopathological significance. The expression of Tspan-1, Jab1 and p27 was detected in HCC tissues, the tissues around cancer (76 cases), and the normal tissues around the liver hemangiomas (10 cases). The overexpression of Tspan-1 and Jab1 was found in HCC tissues, positively correlated with clinical stage and negatively correlated with survival rate. The expression of p27 was found inversely linked to which of Tspan-1 and Jab1. In conclusion, the expression of Tspan-1, Jab1 and p27 is significantly associated with development of HCC. Overexpression of Tspan-1 and Jab1 suggests poor prognosis but overexpression of p27 may expect good prognosis for patients with HCC.

Due to the irregular of diet and overfeeding greasy and surfeit flavor closely associated with hyperuricemia disease, the lipid emulsion containing high cholesterol was used to model. To obtain a more stable and sustained animal model for the efficacy evaluation of traditional Chinese herbs, we observed the influence on the serum uric acid of rat induced by the lipid emulsion compared with high purine diet. 36 SD male rats were randomized to the normal control group, high purine diet group and lipid emulsion group respectively. The general behavior, body weight and daily food intake of rats were observed. The orbital blood was taken to separate into the serum and 24 hours urine was collected. The serum indexes such as UA, BUN, Cr, ALT, AST, TC, TG, LDL-c were determined every 2 weeks, and XOD, ADA enzyme activity were determined at the 4th week. The urine indexes such as UA, Cr and Cua/Ccr were determined at the 4th week. After stopping modeling, the serum UA were determined two weeks and four weeks later respectively. At the 2nd week, the body weight and daily food intake of rats in the lipid emulsion group reduced significantly, and the level of serum UA, BUN, Cr, TC, LDL-c, ATL, AST raised significantly meanwhile TG reduced. At the 4th week, the serum UA in high purine diet group did not raise, and the serum XOD raised obviously while ADA did not; the serum UA in lipid emulsion group was higher significantly, and the serum XOD and ADA raised while Cua/Ccr reduced obviously. At the 6th weeks, the serum UA in both the high purine diet group and lipid emulsion group raised obviously. After stopping modeling, the serum UA in lipid emulsion group still maintained a high level at the 2nd week and back to the normal level at the 4th week. Compared with high purine diet, the hyperuricemia model induced by lipid emulsion forms earlierand more stable. It maybe has great value to study the pharmacodynamics of traditional Chinese medicine treatment to hyperuricemia disease. Its mechanism may be related to increasing XOD and ADA enzyme activity which can promote uric acid synthesis, meanwhile inhibiting of uric acid excretion.

Objective To investigate the blood pressure status of preschool children in urban areas of Qingdao, and to determine the relationship between obesity and blood pressure in preschool children. Methods A stratified cluster sampling method was used to select a total of 13 kindergartens in urban districts of Qingdao. Height, weight, waist circumference, hip circumference and blood pressure of children in three classes were measured. Body mass index (BMI), waist to hip ratio and waist to height ratio were calculated and the relationship between obesity and blood pressure was analyzed. Results The mean values of systolic and diastolic blood pressure in preschool children in urban areas of Qingdao were (95.52±7.66) and (62.78±6.52) mmHg, respectively.The detection rate of hypertension in preschool children was 13.50%. The SBP and DBP were positively correlated with BMI, waist circumference, hip circumference and waist to height ratio. There was a linear regression relationship between body mass index and age and blood pressure. The risk of hypertension in overweight and obese children was 5.191 and 2.824 times of normal body weight, respectively. Conclusions The prevalence of hypertension in preschool children in Qingdao urban areas is high.Overweight and obesity are risk factors for elevated blood pressure.Therefore, while preventing preschool children from obesity, preschool children's blood pressure monitoring and blood pressure monitoring and early intervention of hypertension of preschool children should be implemented.

Comparative analysis of variable region ORF14/15 genes of white spot syndrome virus (WSSV) genome in Guangxi Penaeus vannamei (P. vannamei) could provide useful information for the evaluation of genetic diversity and genetic evolutionary relationship among WSSV isolates from Guangxi, China and other places. Based on geographical and temporal considerations, 40 WSSV-positive P. vannamei samples were collected during the period between May 2010 and July 2013 from Beihai, Qinzhou, and Fangchenggang, which were the main P. vannamei production areas in Guangxi, and the variable region ORF14/15 genes of the WSSV genome from all infected samples were amplified by PCR and then subjected to cloning and sequence analysis. Pairwise and multiple alignment analysis was then conducted to evaluate the degree of genetic divergence between different strains. The variable region ORF14/15 genes from 25 of 40 WSSV positive samples were successfully cloned and sequenced; among the ORF14/15 genes of 25 WSSV-positive strains, 22 was 619 bp in length and 3 was 620 bp. All the 25 Guangxi strains carried a 5949-bp deletion in the ORF14/15 region relative to TH-96-II, which has the longest nucleotide sequence in this region; the deletion of Guangxi strains occurred in the middle region of ORF14/15 gene, with only 190 bp and 429 bp/ 430 bp at 5' and 3' ends, respectively, which were coincident with WSSV-IN-05-I in deletion length and position. Sixteen of 25 Guangxi strains had completely identical nucleotide sequences in the variable re gion, and the homology between other strains also exceeded 97.9%. There were single nucleotide substi tution, deletion, and insertion in the ORF14/15 region of Guangxi strains compared with other strains in GenBank. In the phylogenetic tree based on WSSV variable region ORF14/15, the Guangxi strains were closely related and formed a separate branch with Indian strain IN-05-I, but far from other strains in GenBank. The ORF14/15 gene of WSSV isolates in cultured P. vannamei in Guangxi has a large deletion in the middle of the variable region, and the Guangxi WSSV strains show no significant spatio-temporal differences; the Guangxi strains are closer in genetics to Indian strain IN-05-I than other strains in GenBank.

BACKGROUNDThyroid peroxidase (TPO) is an important autoantigen in Hashimoto's thyroiditis (HT), and almost all epitopes are located in TPO ectodomain. The glycosylation of TPO might contribute to breaking self-tolerance, therefore, purified glycosylated recombinant TPO ectodomain is prerequisite of elucidating its role in the pathogenesis of HT. The aim of our study was to investigate whether the glycosylation has influence on the antigenic determinants of recombinant TPO.

METHODSBac-to-Bac baculovirus expression system was used to generate recombinant human TPO ectodomain. The antigenicity was analyzed by antigen specific enzyme-linked immunosorbant assays (ELISAs). The glycosylation of recombinant human TPO ectodomain of High Five insect cell origin was detected by lectin-ELISAs.

RESULTSTPO ectodomain was recovered from the culture media as a soluble protein, and it was fused with a hexahistidine tag which allowed purification by nickel-affinity chromatography. The recombinant TPO ectodomain could be recognized by all the 54 HT patients and three TPO monoclonal antibodies. Fucose, sialic acid and galactose were all detected on the recombinant TPO ectodomain. Sera TPOAb binding decreased slightly after non-specific deglycosylation of TPO by periodic acid.

CONCLUSIONSHigh Five insect cells derived recombinant human TPO ectodomain had N-glycosylation sites, which might have little effect on recognition by serum TPOAb.

OBJECTIVETo investigate the necessity of modification to the traditional pigtail probe and evaluate its efficiency and therapeutic effect in searching the nasal cut ends and anastomosing the lacerated lacrimal canaliculus.

METHODSEighty-seven patients (including 87 eyes) suffering from canalicular laceration were randomized into two groups: 41 patients treated with traditional pigtail probes (Group A) and 46 with modified pigtail probes (Group B). During the reconstruction of the lacerated canaliculi, the traditional pigtail probe and the modified pigtail probe were used respectively to seek for the nasal cut ends of lacerated lacrimal canaliculi. Peripherally inserted central catheter (PICCTM) silicone tube with diameter of 0.95 mm was intubated as a stent for 4-6 months. The surgical outcomes were retrospectively analyzed after stent removal.

RESULTSIn Group B, the primary success rate of searching the nasal cut ends of lacerated lacrimal canaliculi was 93.48% (43/46) and the final success rate was 97.83% (45/46). No false passage formed in Group B. Statistical significance was found between Group A and Group B as the primary success rates of searching the nasal cut ends (X(2) equal to 10.522, P less than 0.01) and the false passage forming rates were concerned (X(2)) equal to 4.704, P less than 0.05), whereas no significance was found between the two groups as the final success rates were concerned (X(2) equal to 0.007, P larger than 0.05). The mean time of searching the nasal cut ends of lacerated lacrimal canaliculi in Group B was (5.02+/-0.73) minutes and the mean time of operation was (33.90+/-4.84) minutes, and both were significantly shorter than those of Group A (t(1) equal to 9.779, t(2) equal to 10.700, P less than 0.01). The cure rate of Group B was 95.65%, though higher than that of Group A, no statistical significance was found (Z equal to -0.007, P larger than 0.05). Totally, 2 patients (2.30%) were found to be absent of common canaliculus and underwent bicanalicular nasal intubation in the two groups.

CONCLUSIONSPigtail probes are efficient and convenient apparatus for searching the nasal cut ends of the lacerated lacrimal canaliculi in the reconstruction of canalicular laceration. Necessary or proper modifications to the pigtail probes can minimize the risk of iatrogenic damages or complications and enhance the efficiency and therapeutic effect of canalicular repair.

OBJECTIVETo determine how patients with infiltrating lobular carcinoma (ILC) differ from patients with the more common infiltrating ductal carcinoma (IDC), and observe the different expression patterns of E-cadherin and p120-catenin proteins in both ILCs and IDCs.

METHODSThe patients with ILC admitted to our hospital from Jan 1999 to Dec 2006 and patients with IDC from Jan 2000 to Dec 2000 were included in this study. All their pathological slides were reviewed, and their clinical data and treatment variables were analyzed retrospectively. Then the expression patterns of E-cadherin and p120-catenin proteins in both ILCs and IDCs were detected by immunohistochemistry on tissue microarray.

RESULTSThe 5-year overall survival was 81.7% for ILCs and 79.1% for IDCs (P = 0.055). The 5-year disease-free survival was 61.8% for ILCs and 83.7% for IDCs (P < 0.001). Cytoplasmic localization of p120-catenin and loss of E-cadherin expression were more common in ILCs than in IDCs. The complete losses of E-cadherin in ILCs and IDCs were 55.6% (20/36) and 20.4% (45/221, P < 0.001), respectively. The p120-catenin showed a diffuse cytoplasmic localization in 66.7% (24/36) of ILCs and 16.3% (36/221) of IDCs (P < 0.001). Interestingly, the cytoplasmic localization of p120-catenin was clearly associated with the absence of E-cadherin expression in ILCs (P = 0.002), cytoplasmic localization of p120-catenin and absence of E-cadherin expression were observed 55.6% (20/36) in ILCs compared with 4.1% (9/221) in IDCs (P < 0.001).

CONCLUSIONILC has several specific biological and prognostic characteristics which are different in IDC. Different expression patterns of E-cadherin and p120-catenin proteins can be helpful to recognize ILC from IDC.
