Objective:To determine the shear bond strength and analyze the bonding mechanism of home-made and imported nickel-based alloys to resin-veneers.Methods: Home-made and imported alloy disks were cast by lost-wax technique and embedded in acrylic resin fabricating cylinders.Sixteen specimens of each alloy were divided into 2 subgroups: thermocycling group and non-thermocycling group.Specimens in thermocycling groups were submitted to thermocycling(300 cycles) and those in non-thermocycling groups were just stored in water at 37?C for 24 h(0 cycles).Then the shear bond strength values were determined by universal testing machine.The highest shear bond strength values were recorded and metallurgical analysis was performed on the interface between alloys and resin-veneers.Results: The shear bond strength values of both alloys to resin-veneers were relatively high either before or after thermocycling.The shear bond strength values of home-made alloy+thermocycling group,imported alloy+thermocycling group,home-made alloy+non-thermocycling group and imported alloy + non-thermocycling group were(10.50?2.72),(13.12?2.82),(15.51?3.04) and(18.44?3.15) MPa,respectively.The bond strength was significantly different before and after thermocycling for both alloys(P

BACKGROUND: Human apolipoprotein H which characterizes by polymorphism is related to metabolism of triacylglycerol (TG) and function of platelet; therefore, it is suspected that it is possibly related to coronary atherosclerotic heart disease (CAHD).OBJECTIVE: To investigate the correlation among apolipoprotein H(ApoH) exon-8 polymorphism with CAHD and its effect on lipometabolism.DESIGN: Case-controlled observation.SETTING: Department of Cardiology, Haici Medical Group, Qingdao,Shangdong. PARTICIPANTS: 110 CAHD patients selected from Qingdao Haici Medical Group were regarded as CAHD group, and other 100 healthy subjects were regarded as control group.METHODS: 2 mL blood was collected from peripheral vein of all cases. Polymerase chain reaction and technique of restriction fragment length polymorphism were used to determine the genotype of ApoH exon-8; meanwhile, lipids were measured with oxidase technique.MAIN OUTCOME MEASURES: ① polymorphism of ApoH exon-8 genotype; ② gene frequency of ApoH exon-8 (Try316Ser); ③ comparisons of lipid level of cases with various genetypes.RESULTS: All 210 cases were involved in the final analysis. ① G1025C (Try316Ser) existed in ApoH exon-8, including types of GG and GC, butnot CC type. ② The frequency of GC in the CAHD group was 25.5％, and the frequency of C allele was 0.13; they were significantly higher than those in control group (10％, 0.05, P ＜0.05). ③ TG level in genotype GC of CAHD group was significantly higher than that both in GG genotype and in any genotype of control group [(1.38±0.24), (1.16±0.10),(1.09±0.78), (1.12±0.76) mmol/L, P ＜ 0.05]. Level of low-density lipoprotein cholesterol (C-LDL) was higher in CAHD group than that in control group (P＜0.05).CONCLUSION: The polymorphism of ApoH exon-8 is closely related to CAHD and TG level.

Objective To explore the effective treatment of acute deep venous thrombosis(DVT) of left lower extremity accompanied with Cockett syndrome.Methods The data of 16 patients with acute DVT of left lower extremity accompanied with Cockett syndrome,who were admitted to our hospital from August,2004 to January,2008,were analyzed retrospectively.Inferior vena caval filters were inserted and thrombectomy was done to all of the 16 patients;PTA and stent insertion were done in 13 patients and PTA only in the other 3 patients.Anticoagulation,thrombolysis and antiplatelet therapy were given postoperatively to all the patients.Results There was no death or pulmonary embolism in all 16 patients;Forteen patieats had good outcome,2 had acute DVT of left lower extremity one day after surgery,and limbs swelling subsided after anticoagulation,thrombolysis and antiplatelet treatment before their discharge.Forteen patients were followed up from 1 month to 25 months(average 11 months),and 2 patients had post-DVT syndrome,but the others had no swelling or varicose veins of the lower extremity.Conclusions Most patients with acute DVT of left lower extremity accompanied with Cockett syndrome could get satisfactory outcome with thrombectomy,PTA and stent insertion.

Objective To evaluate the diagnostic value of medical imaging for primary thyroid malignant lymphomathe(PTML). Methods The medical imaging of 45 PTML cases admitted between January 2000 and December 2014 in the First Hospital of China Medical University were ana?lyzed retrospectively. Results In ultrasound imaging,PTML exhibits a hypoechoic mass and enhancement of posterior echoes,the uninvolved thy?roid tissues also exhibit low echoes but they have clear boundaries with extremely low echo areas of PTML.CT imaging of PTML often shows homoge?neous enlargement of the lobes of the thyroid gland and isthmus with densities lower than the adjacent muscles. In contrast?enhanced CT images,le?sions are moderately enhanced,but they are obviously enhanced in the edge or internal area and the degree of enhancement remains lower than that of the adjacent muscle. Calcification is uncommon. A lesion withcold nodulecan be observed in ECT imaging. Conclusion The characteristic im?aging findings are helpful for preoperative diagnosis of PTML.

Objective To evaluate the association between the polymorphisms of BT-H4 gene and the risk of breast cancer, a case-control study was conducted in the population of Heilongjiang province, China. Methods We genotyped the single nucleotide polymorphisms of rs10754339, rs10801935 and rs3738414 in B7-H4 gene by PCR-RFLP in a Chinese population consisting of 287 breast cancer cases and 305 controls matched for age and sex, tagged all common haplotypes (frequency ≥ 1%), and analyzed the differences between patients and normal controls. Results Our data indicated that in rs10754339, the frequencies of G allele, AA genotype and AG genotype were significantly different between patients and controls (P=0.030, OR 1.359, 95 % CI 1.030-1.794; P=0.018, OR 0.671, 95 % CI 0.482-0.935; P=0.029, OR 1.455, 95 % CI 1.038-2.038, respectively). In rs3738414, the frequencies of A allele, GG genotype and AG genotype were significantly different between patients and controls (P=0.0008, OR 0.604, 95 % CI 0.455-0.803; P=0.001, OR 1.804, 95 % CI 1.289-2.253; P=0.005, OR 0.612, 95 % CI 0.435-0.862). The frequencies of AAA haplotype and GAG haplotype were significantly different between patients and controls (P=0.0015, OR 0.614, 95 % CI 0.456-0.828; P=0.0003, OR 1.954, 95 % CI 1.363-2.803). Conclusion Polymorphisms of B7-H4 gene appear to be associated with breast cancer in the population of Heilongjiang province, China.

Objective To explore the clinical features and the gene mutations in MECP 2 duplication syndrome. Methods The clinical data of a child with developmental retardation and hypophrenia accompanied with respiratory tract infection was analyzed retrospectively. Microarray analysis technique was used to detect the genes in the patient and his family. The pertinent literature was reviewed. Results A 1-year and 7-month old boy was found to have hypotonia, developmental delay, and recurrent respiratory tract infections after birth. Microarray analysis showed a duplication of 441.88kb in Xq28 area and diagnosis of MECP2 duplication syndrome was confirmed. His grandmother, mother, and two aunts were found duplication of 441.73-441.88kb in Xq28 area, all of whom were MECP2’s female carrier. Conclusions The improvement of chromosome chip technology inspection is helpful to the early diagnosis of MECP2 duplication syndrome.

Objective To investigate the characteristics and risk factors of central lymph node metastasis in clinically node negative (cN0) papillary thyroid carcinoma (PTC) (T1 or T2 stage) coexisting with Hashimoto' s thyroiditis (HT).Methods A total of 398 patients undergoing thyroidectomy with central lymph node dissection were enrolled in the study.Patients were divided into the trial group (PTC with HT)and the control group (PTC without HT).The difference of the clinicopathological characteristics between the 2 groups and risk factors for central lymph node metastasis were analyzed.Results Among the total 398 patients,98 (24.6％)had coexistent HT.Central lymph node metastasis rate was similar in the 2 groups (40.8％ vs 41.3％).The number of dissected central lymph nodes was significantly more in the trial group than in the control group (4.9 vs 2.9,P＜0.01) while the number of metastatic lymph nodes had no statistical significance between the 2 groups (1.0 vs 1.0).Univariate analysis showed that tumor size＞1 cm was significantly associated with central lymph node metastasis in the trial group (P＜0.01).Male,＜45 years,tumor size＞1 cm,and tumor located in the middle/lower third of lobe were all significantly associated with central lymph node metastasis in the control group (P＜0.01).Multivariate analysis showed that tumor size＞1 cm was independent predictor for central lymph node metastasis in the trial group,while female,＜45 years,tumor size＞1 cm,and tumor located in the middle/lower third of lobe were all independent predictors for central lymph node metastasis in the control group.Conclusions The number of central lymph nodes was larger in cN0 PTC coexisting with HT patients than that in PTC patients,but there was no statistical difference in the number of metastatic lymph nodes between cN0 PTC with and without HT.Central lymph node dissection is recommended when tumor size 1 cm in cN0 PTC coexisting with HT patients.
