Objective To investigate the distribution of single nucleotide polymorphisms(SNPs) on retinol binding protein 4(RBP4) genes and forkhead box O1 (FOXO1) gene, and their relationships with the occurrence of type Ⅱ diabetes mellitus (T2DM) in Chinese Han population. Methods Totally ten SNPs on RBP4 and FOXO1 were determined in 384 T2DM patients and 384 normal controls by TaqMan probe genotyping and agarose gel electrophoresis methods. And their serum level of fasting blood glucose (FBG), total cholesterol (TC) and trigly- ceride (TG) were also estimated. Results For RBP4, there was no significance for various genetypes and alleles including - 803 G > A, + 5169 C > T, and + 6969 G > C between two groups (P > 0.05). Each genotype had no relationships with T2DM (using adjusted logistic regression models). No haplotype was associated with T2DM. For FOXO1, among seven SNPs typed, significant variation was found in the frequency distribution of rs7324943 G/T in the two groups(χ~2=4.02, P = 0.044), and further stratification analysis showed that in subjects of aged 40 and non-hypertension, there was a higher risk of T2DM in GT heterozygous carriers than in GG homozygous carriers (OR = 1.47, 1.80), T allele carriers showed higher risk than non-T carriers (OR = 1.42,1.79). For rs17592236 C/T, though no significant frequency variation was found between two groups (χ~2 = 0.39, P = 0.401), but in subjects of aged ≤ 40, stratification analysis showed dramatically increased risk of T2DM in CT and TT carriers than in CC carriers (OR = 6.33,10.15), T allele carriers showed 7. 11-fold higher risk than non-T carriers. A haplotype CT related to T2DM susceptibility was also found, which could decrease the risk of its carriers by 28%. Conclusions For BBP4, the polymorphisms of - 803 G > A, + 5169 C > T, and + 6969 G > C had no relationships with T2DM in Chinese Han population. For FOXO1, the polymorphism of rs7324943 G/T,rs17592236 C/T and a haplotype CT were found related to the susceptibility of T2DM in Chinese Han population. Yet further studies are necessary to explain the impact of these polymorphisms on the disease occurrence.

Objective To study the clinical and pathologic features of chromphobe renal cell carcinoma (ChRCC) and to evaluate the conventional pathologic prognostic parameters in prognosis.Methods Seventy-five cases (42 males and 33 females) with pathological confirmed ChRCC (36 on the left and 39 on the right kidney) after nephrectomy during 1998 to 2009 were retrospectively analyzed. Patient's age ranged from 25 to 74 years, with a mean age of 56 years. Evaluation of conventional prognostic parameters was carried out. Kaplan-Meier survival curve was used to study the survival relationship. Results The mean tumor diameter was 7.3 cm. The majority of tumor macroscopic surface color was gray and yellow or gray and red. The majority of tumor cells were big polygon chromphobe cell or small round eosinophils. The TNM stages of these ChRCC were as follows: 30 cases in T1N0M0, 1 in T1N0M1, 26 in T2N0M0, 1 in T2N0M1, 11 in T3N0M0, 3 in T3N0M1, 1 in T3 N1 M0, 1 in T4 N0 M1 and 1 in T4 N1 M1. The pathologic grade of ChRCC was G1 in 3 cases, G2 in 24cases, G3 in 46 cases and G4 in 2 cases. All the 75 cases were followed up for 9 to 93 months (mean 44months), 7 patients died and others were alive without recurrence and metastasis. 3-year and 5-year survival rates were 93.3% and 90. 7%, respectively. The univariable analysis showed that tumor size (P=0. 028), TNM stage (P＜0. 001) were associated with tumor progression. The multivariable Cox regression model revealed that TNM stage was an independent predictor of aggressive ChRCC. Conclusions The ChRCC tumors are generally larger than other types of RCC and with a favorable prognosis. Fuhrman nuclear grade is not suitable for ChRCC. TNM stage is an independent predictor of aggressive ChRCC.

AIM: To explore the differentiation and the functional behavior of marrow mesenchymal stem cells (MSC) transplanted into the cerebral infarction area after cerebral middle artery ischemia in rats. METHODS: MSC were isolated from human rib marrow and cultured in L DMEM medium in vitro. The model of rat cerebral infarction by cerebra middle artery occlusion was established, and the identified MSC were transplanted intracerebrally 10 days later. Immunohistochemistry technique was used to identify the cell survivor and its differentiation to the neurogenesis in the transplantation site, and at 2 weeks and 6 weeks after transplantation, the functional tests were comparatively studied. RESULTS: The results showed that the survivor of transplanted MSC was differentiated to neural phenotype cells, and the functional behavior of the injury rats was recovered significantly after MSC transplantation (P

ABSTRACT:Objective To explore the expression of chemokine receptor CX3CR1 in severe acute pancreatitis (SAP)rats model and to estimate whether it can be a potential predictor of SAP.Methods Forty Sprague-Dawley rats were randomly divided into sham-operation (SO)group (n =20)and SAP group (n =20).Rats were killed at 6 h,12 h,24 h and 48 h after model induction.The serum level of CX3CR1 was measured by enzyme-linked immunosorbent assay (ELISA).The expression of CX3CR1 protein in the pancreas,lung and kidney were detected by immunohistochemistry.Results The serum level of CX3CR1 in SAP rats increased gradually after model induction and reached the peak at 24 h (542.4 pg/mL),which were significantly higher than those in SO group (P <0.05).The expression of CX3CR1 was found in the pancreas,lung and kidney tissues of SAP rats and higher than that in SO group.Meanwhile,the expression of CX3CR1 reached the peak at 24 h in the pancreas and lung and at 48 h in the kidney.Conclusion This study suggests that the chemokine receptor CX3CR1 may be one effective index for predicting the severity of acute pancreatitis and deserves further research.

BACKGROUND: As dental implants, pure titanium and Ti-6Al-4V has achieved broad clinical applications, but they also contain toxic vanadium and aluminum element. Moreover, their elastic modulus is so high as to produce stress shield. OBJECTIVE: To examine the micro-hardness and elastic modulus of the self-made Ti-30Nb-8Zr-2Mo titanium alloy. DESIGN, TIME AND SETTING: An observational experiment was performed at the laboratory of College of Material Science and Engineering at Hebei University of Technology between March 2003 and February 2006. MATERIALS: Titanium alloy was prepared using titanium sponge (≥ 99% purify), niobium strip (≥ 99.9% purify), molybdenum powder (≥ 99% purify) and zirconium sponge (≥ 99.4% purify).METHODS: The micro-hardness of the specimens was determined after uniformly annealing, hot-forging and solution. Compression test was conducted on post-aging samples. MAIN OUTCOME MEASURES: Hardness and stress-strain curve.RESULTS: The maximal alloy strength was obtained after solution under 800 ℃ for 0.5 hours. Post-aging alloy's hardness was improved significantly although little change occurred on solution alloy. Compressive strength of alloy samples was 1 054 MPa, while elastic modulus reached 16.5 GPa. CONCLUSION: Both micro-hardness and elastic modulus of the self-made Ti-30Nb-8Zr-2Mo titanium alloy have satisfied performance requirements for dental implant materials.

We retrospectively analyzed clinical and imaging data of 26 children with split cord malformations (SCMs). Based on Pang's classification, 14 SCMs were defined as type Ⅰ and 12 as type Ⅱ.Neural function was markedly improved in 20 patients postoperatively. Three of 4 children who did not undergo surgical treatment had neural function deteriorated. Two children lost follow-up. We suggest that Pang's Classification of SCMs may be useful in describing pathological changes and guiding surgical procedure; imaging examine (including MRI, CT and X-ray) would play a significant role in confirmed SCMs diagnosis; and surgical operation should focus on eliminate and prevent spinal cord damnification.
