Objective: To investigate the effects LASS2 gene on the metastasis of human hepatocellular carcinoma cell line, HCCL3. Methods: The expression level of LASS2 mRNA in HCCLM3 cells was analyzed by northern blotting in high metastatic HCCLM3 cells and in low metastatic MHCC97-L cells. The eukaryotic expression vector pCMV-HA2-LASS2 was constructed and transfected into HCCLM3 cells. The stable clone with LASS2 overexpression was selected by G418 screening. The metastatic ability of HCCLM3 cells such as migration and invasion was observed in vitro after LASS2 overexpression. The synthesis, secretion, and activation of matrix metaloproteinase-2 (MMP-2) were examined by western blotting, zymography, and in situ zymography. Results: Northern blot analysis showed that the level of LASS2 mRNA decreased in HCCLM3 cells compared with MHCC97-L cells. LASS2 overexpression inhibited the ability of migration and invasion of HCCLM3 cells (P <0. 001 ). The synthesis of MMP-2 was not different but the secretion and activation of MMP-2 were down-regulated in HCCLM3 cells afterLASS2 overexpression. Conclusion: Overexpression of LASS2 down-regulated the secretion and activation of MMP-2 in HCCLM3 cells and inhibited the cell ability of migration and invasion indicating that LASS2 gene had inhibitory effects on the metastasis of HCCLM3 cells.

OBJECTIVE: This study aimed to explore the relationship among expression of Survivin and MRP and drug resistance in NPC. METHOD: Expression of Survivin were detected by immunohistochemistry method in 45 cases of NPC and 24 cases of normal mucous membrane of nasopharynx (NMMN). The relationship between expression of Survivin and pathological factors in NPC were analysized. Expression of Survivin and MRP were detected in 31 patients of NPC with paclitaxel resistance and 20 patients of NPC without paclitaxel resistance. The relation- ship among the expression of Survivin or MRP and paclitaxel resistance in NPC were analysized. The paclitaxel resistance cell line, 5-8F-PTX(+); was established by a step-increased method. The expression of Survivin and MRP were detected by western blot in 5-8F-PTX(+) and 5-8F. RESULT: The positive were 71. 1% (32/45) in NPC and 8.33% (2/24) in NMMN. And there were significantly differences between them (P < .05). There were relationship among expression of Survivin and differentiation degree, lymph node metastasis, distant metastasis, and clinic stages of NPC. The positive were 75.9% (31/39) in moderately differentiated NPC and 16.7% (1/6) in lowly differentiated NPC, respectively. There were significantly differences between them (P < 0.05). The positive of Survivin were 83.9% (26/31) in NPC patients with paclitaxel resistance and 45.0% (9/20) in NPC patients without Paclitaxel resistance, respectively. There were significantly differences between them (P < 0.05). The positive of MRP were 87.1% (27/31) in NPC patients with paclitaxel resistance and 40.0% (8/20) in NPC patients without paclitaxel resistance, respectively. There were significantly differences between them (P < 0.05). There were positive correlation between the expression of Survivin and MRP in NPC patients with Paclitaxel resistance. The expression of Survivin and MRP were higher in 5-8F-PTX(+) than in 5-8F. The IC50 of paclitaxel, cDDP, 5-FU and Vincristine were significantly higher in 5-8F-PTX(+) than in 5-8F. CONCLUSION There were relationship among the expression of Survivin and difference, metastasis and TNM stages of NPC. Survivin may serves as a molecular marker for development and progress in NPC. There were relationship among the high expression of Survivin and MRP and increasing of drug resistance in NPC.

Objective To explore the changes of bone metabolic markers during early stage of preterm infants, as well as the relationship with their nutrition status. Methods Preterm infants with gestational age 30-35 weeks admitted to our Hospital were collected from November 2012 to April 2013. Venous blood samples obtained within 24 hours after birth and between 8:00-9:00 AM two weeks after birth were used to determine the Serum β-CTx, osteocalcin ( OC) and propeptide of type I procollagen (PINP) levels by Electro-Chemiluminescence. Analysis of changes of these bone metabolic markers and their relationship with early stage nutrition related indicators were also performed. Results A total of 60 premature infants were collected. There was no significant correlation among serum β-CTx, OC and PINP within 24 hours after birth ( r=0. 170, P＞0. 05 ) . The Serum β-CTx within 24 hours after birth was negatively correlated with gestational age (r= -0. 603, P＜0. 05), whereas the serum OC within 24 hours after birth was positively correlated with gestational age ( r=0. 581, P＜0. 05 ) . However, PINP wasn′t correlated with gestational age significantly (r=0. 134,P＞0. 05). Serumβ-CTx, OC and PINP at 2 weeks after birth increased significantly from the baseline level detected within 24 hours after birth ( P＜0. 05 ) .Δβ-CTx was positively correlated with ΔOC (r=0. 600,P＜0. 05). There was no significant correlation between ΔPINP and Δβ-CTx (r=0. 045,P＞0. 05), as well as ΔOC and ΔPINP (r=0. 110,P＞0. 05).ΔOC was positively correlated with average daily calorie ( P＜0. 05 ) and average daily P/E ( P＜0. 05 ) , negatively correlated with cumulative loss of caloric ( P＜0. 05 ) . There was no significant correlation between Δβ-CTx or ΔPINP with nutrition related indicators of this study. Conclusions Serum OC within 24 hours after birth of preterm infants and their gestational age are positively correlated, while β-CTx detected at the same time and gestational age are negatively correlated. Vigorous metabolism of premature bone occurs during the first two weeks after birth, as the serum β-CTx, OC and PINP levels increased significantly. We suggest that reasonable calorie intake and appropriate protein calorie ratio at early stage after birth is very important for the development of bone of preterm infants.

OBJECTIVETo investigate the penile erectile function of hospitalized male patients with cardiovascular diseases, the incidence of erectile dysfunction (ED) in this cohort, and the relationship of ED with cardiovascular diseases and its risk factors.

METHODSUsing a self-designed questionnaire, we conducted an investigation among the hospitalized patients in the Department of Cardiovascular Diseases of the First and Second Affiliated Hospitals of Xi'an Jiaotong University. We measured their body height, body mass index (BMI), waist circumference, hip circumference, and blood pressure, obtained their personal data, past history, metabolic indexes, and erectile function scores by IIEF-5, and analyzed the risk factors of ED using univariate and multivariate logistic regression and OR analyses.

RESULTSTotally, 225 valid questionnaires were included in this investigation, which showed a 66.7% incidence of ED, 15.8% mild, 27.0% mild to moderate, 17.6% moderate, and 6.3% severe. The incident rates of ED in the 18-35 yr, 36-49 yr, 50-65 yr, and > 65 yr age groups were 13.6%, 39.1%, 89.2%, and 91.2%, respectively. Univariate logistic regression analysis manifested that the risk factors of ED in the patients with cardiovascular diseases included age (OR = 3.122, 95% CI 2.040-4.779), smoking (OR = 1.768, 95% CI 1.209-2.584), BMI (OR = 1.261, 95% CI 1.114-1.427), total cholesterol (OR = 1.77, 95% CI 1.339-2.340), TC/HDL (OR =1.715, 95% CI 1.349-2.181), hypertension (OR = 1.717, 95% CI 1.110-2.658), and coronary heart disease (OR = 2.235, 95% CI 1.169-4.275), while multivariate logistic regression analysis showed the risk factors to be age (OR = 4.99, 95% CI 2.264-10.998), financial condition, (OR = 2.804, 95% CI 1.127-6.976), smoking (OR = 2.109, 95% CI 1.179-3.772), BMI (OR = 1.414, 95% CI 1.136-1.760), and TC/HDL (OR = 2.001, 95% CI 1.016-3.943).

CONCLUSIONThe incidence of ED is high in hospitalized patients with cardiovascular diseases and rises with the increase of age. Age, smoking, financial condition, BMI, and TC/HDL are the risk factors of both ED and cardiovascular diseases, and financial condition is closely associated with ED.
