OBJECTIVETo study the bonding capability when Ni-Cr porcelain alloy was added with Ti, compound rare earth metals and removed the element of Be.

METHODSNi-Cr-Ti porcelain alloys manufactured by Institute of Metal Research of Chinese Academy of Sciences were tested. The test alloys were divided into three groups according to whether containing Be and compound rare earth metals or not. And HI BOND Ni-Cr base-metal alloy was chosen as control. The metal-ceramic specimens were prepared for shear test, scanning electron microscope (SEM) and energy spectrum analysis.

RESULTSThe shear bond strength of the four groups were analyzed. No significant difference were observed among them (P > 0.05). No crackle was found and they were contacted tightly between the porcelain and metal. The composition and contents of the four groups' interfaces were closed.

CONCLUSIONThe shear bond strength of the self-made Ni-Cr-Ti porcelain alloys all can satisfy the clinical requirements. Experimental groups containing Ti, compound rare earth metals and removing the element of Be can be used as better recommendation for clinical practice.

OBJECTIVETo evaluate the application of ultrasonography in diagnosis and treatment of the upper arm radial neuritis.

METHODSFrom 2005.12 to 2011.7, 10 patients of the upper arm radial neuritis were selected and included 6 males and 4 females with an average age of 32 years old ranging from 20 to 40 years. The course of disease ranged from 4 months to 2 years. All patients feel pain on the outside of upper arm. Medical examination showed Tinel's sign masculine, and the muscle force included extension of wrist and fingers were reduced. Upper arm radial neuritis were diagnosed by clinical sign and medical examination. All patients underwent ultrasonography examination, electrophysiology examination and operation. The ultrasonography were compared to the results of electrophysiology examination,and ultrasonography were compared to intra-operative findings and pathology examination.

RESULTSThe ultrasound images showed average diameter of affected limb radial nerve were (0.29+/-0.04) cm, average area were (0.23+/-0.05) cm2, and all of these were greater than uninjured side. Ultrasonograghic findings and orientation of radial neuritis were consistent with intra-operative findings,and the results of ultrasonography were consistent with the results of pathology examination.

CONCLUSIONUltrasonography examination provide morphological evidence for the diagnosis and treatment of the upper arm radial neuritis.

Objective To study the genotypes of 102 strains of methicillin-resistant Staphylococcus aureus(MRSA)collected consecutively in 2002 in our hospital Method Multiplex PCR was used to genotype Staphylococcal chromosomal cassette mec(SCCmec)element and its variants.Results Among 102 strains of MRSA,the genotypes were as follows:SCCmec-Ⅲ(94 strains),SCCmec-ⅢA(4 strains), SCCmec-Ⅳ(2 stains),SCCmec-Ⅰ(2 stains).Conclusion The predominant genotype of MRSA circulating in this hospital in 2002 was SCCmec-Ⅲ by multiplex PCR.

OBJECTIVETo investigate whether Hantavirus (HV) and Orientia tsutsugamushi ( OT) can naturally infect and coexist in their host and role.

METHODSBy field epidemiological study, Leptotrombidium scutellare (3829) was collected and separated from mice(166) in epidemic areas. The cells of mites separated from their host and role were cultured. PCR was used to detect HV-RNA and OT-DNA in the cell culture.

RESULTSIn 105 Apodemus agrarius, 3 HV-RNA positive, 2 OT-DNA positive and 2 coinfection with HV and OT were detected;in 41 Brown rattus, 2 HV-RNA positive, 1 OT-DNA positive and 1 co-infection with HV and OT were detected. From 15 mites co-infected with HV and OT, 2 strains of HV pathogen, 2 strains of OT pathogen were separated and 1 HV and OT pathogen in the same mite were separate.

CONCLUSIONThe study demonstrates that co-infection of HV and OT did simultaneously exist in wild Leptotrombidium scutellare. This theory has some significance to the epidemic and precaution of HV and OT.

BACKGROUND AND OBJECTIVEColorectal cancer is one of the most common malignant cancers in the world. Although the clinicopathologic staging is the golden criterion for the prognosis at present, the optimum prognostic criteria for colorectal cancer should be a combination of the clinicopathologic staging and the molecular markers. However, there are currently no molecular markers available for the prognosis of colorectal cancer. Several tumor-suppressor genes associated with colorectal cancer have been mapped at the 18q21-23 region. In this study we detected the frequency of loss of heterozygosity (LOH) at chromosome 18q and investigated the relationship between LOH and clinicopathologic features and its prognostic value for patients with stage II colon cancer.

METHODSA total of 106 samples of tumor tissues and corresponding normal mucosa from patients with sporadic stage-II colon cancer were included in this study. All the samples were formalin-fixed and paraffin-embedded. DNA was extracted from tumor tissues and LOH of D18S474, D18S55, D18S58, D18S61 and D18S64 at chromosome 18q was analyzed using polymerase chain reaction (PCR), polyacrylamide gel-electrophoresis, and DNA sequencing method. Multivariate analysis for association between LOH and prognosis in colon cancer patients was performed with Cox proportional hazards regression model.

RESULTSThe median follow-up time was 68 months. For 106 patients, 5-year survival rate was 83.6%, which was associated with age and gross tumor type (P = 0.011 and 0.034, respectively). Among 102 patients who were eligible for LOH information, the overall frequency of LOH is 49.0% (50/102), and that of LOH at 5 microsatellite loci of D18S474, D18S55, D18S58, D18S61, and D18S64 was 30.2% (26/86), 23.4% (18/77), 28.6% (20/70), 35.0% (28/80), and 20.8%(15/72), respectively. The occurrence of LOH was significantly associated with tumor location and histopathologic grade (P = 0.023, 0.016 and 0.005, respectively). LOH was more frequent on the left-side, poorly-differentiated adenocarcinoma, and nonmucinous colon cancers. The occurrence of 18q-LOH was significantly associated with 5-year overall survival rate and disease free survival rate (P = 0.008 and 0.006, respectively). The occurrence of 18q-LOH at the loci of D18S474 and D18S61 was significantly associated with 5-year overall survival rate (P = 0.010 and 0.005, respectively). The multivariate analysis showed that only the occurrence of 18q-LOH was significantly associated with prognosis (P = 0.021).

CONCLUSIONSThere is a high occurrence of LOH at the loci of 18q. The expression of LOH is significantly associated with tumor location and histopathologic grade. The occurrence of 18q-LOH is an independent poor prognostic factor for the patients with stage-II colon cancer.

PURPOSE: Urapidil is putatively effective for patients with hypertension and acute heart failure, although randomized controlled trials thereon are lacking. We investigated the efficacy and safety of intravenous urapidil relative to that of nitroglycerin in older patients with hypertension and heart failure in a randomized controlled trial. MATERIALS AND METHODS: Patients (>60 y) with hypertension and heart failure were randomly assigned to receive intravenous urapidil (n=89) or nitroglycerin (n=91) for 7 days. Hemodynamic parameters, cardiac function, and safety outcomes were compared. RESULTS: Patients in the urapidil group had significantly lower mean systolic blood pressure (110.1±6.5 mm Hg) than those given nitroglycerin (126.4±8.1 mm Hg, p=0.022), without changes in heart rate. Urapidil was associated with improved cardiac function as reflected by lower N terminal-pro B type natriuretic peptide after 7 days (3311.4±546.1 ng/mL vs. 4879.1±325.7 ng/mL, p=0.027) and improved left ventricular ejection fraction (62.2±3.4% vs. 51.0±2.4%, p=0.032). Patients given urapidil had fewer associated adverse events, specifically headache (p=0.025) and tachycardia (p=0.004). The one-month rehospitalization and all-cause mortality rates were similar. CONCLUSION: Intravenous administration of urapidil, compared with nitroglycerin, was associated with better control of blood pressure and preserved cardiac function, as well as fewer adverse events, for elderly patients with hypertension and acute heart failure.
