Purpose To study the expression of HK2 in human prostate cancer (PCa) tissues and its effect on malignant phenotype of prostate cancer cells.Methods HK2 expression in PCa tissues was determined by microarray database and immunohistochemical staining.Subsequently,the change of cellular phenotype was detected by glycometabolism kit,CCK-8 kit,and flow cytometry after HK2 knockdown.Results HK2 expression was elevated followed by prostate cancer development.HK2 depletion inhibited cellular proliferation and aerobic glycolysis,and increased the ratio of early apoptosis.Conclusion HK2 expression increases in the process of PCa malignant progression.It plays a critical role in cellular proliferation,glycometabolism,and apoptosis,the mechanism of which needs further exploration.

Objective To investigate the effect of obesity on physical stamina of college students.Methods The physical stamina and obese status of 7353 college students were measured. The relationship between obese degrees and the scores of step trial, vital capacity, grip, standing long jump was analyzed.Results The male's and female's vital capacity score was obesity students > pre-obesity students > normal students > thin students ( P<0.01). The male's step trail score was the normal body weight students and pre-obesity students > obese students ( P<0.05). The male and female's standing long jump score was normal students > pre-obesity students > obesity students ( P<0.05). The male and female's grip score was obesity students > pre-obesity students > normal students > thin students ( P< 0.05 ).Conclusion The lung function and the arm power of college students are increasing with the rise of obese degrees. The heart function and breakout force are decreasing with the rise of obese degrees.

Objective To investigate the role of intestinal fatty acid binding protein(I-FABP)in evaluating intestinal dysfunction of septic rats and the effect of glutamine on I-FABP expression.Methods Rats were divided into 3 groups,control group were only fed with Peptisorb,model group were fed with Peptisorb after intraperitoneal injection with E.coli endotoxin lipopolysaccharidegiven and glutamine group were added glutamine on basis of model group.The correlation between serum I-FABP level and intestinal mucosa damage index were analyzed and the concentrations of serum I-FABP in each group were observed and compared. Results The serum level of I-FABP in rats were correlated with the Chiu’s score of intestinal mucosa,mucosa thickness and villus length(P<0.05 ).Compared with control group,the concentration of serum I-FABP in model group and glutamine group were significantly increased(P<0.05),but which in glutamine group was lower than that in model group(P<0.05).Conclusions Serum I-FABP could be an non-invasive diagnosis index for evaluating acute intestinal dysfunction in septic rats.In addition,dietary glutamine supplementation may ameliorate sepsis-induced intestinal epithelial injury in rats.

Co-processed excipients withgelatinized or non-gelatinized starch were prepared by spray drying. Powder and tablet properties of corocessed excipients prepared were compared with those of physical mixtures and spray-dried lactose. Their applicability in traditional Chinese medicine (TCM) powder tableting was tested on two TCM extracts, i.e., the gardenia extract and the Herba Sedi extract. It was shown that gelatinizing starch before co-spray drying with lactose could improve the performance and efficiency of starch as a binder, resulting in remarkable improvement in physicomechanical properties of co-processed excipients prepared. Conpared to self-made and commercially available spray-dried lactose, co-processed excipients achieved better compactability and higher drug loading for TCM extracts. In conclusion, the lactose-gelatinized starch co-processed excipient, with excellent physicomechanical properties, is promising to be explored as a new excipient for direct tableting.

Objective To establish a uremic apoE-/- mouse model to observe serum biochemical parameters and features of aortic root atherosclerosis (AS) in the model. Methods A uremic model was induced surgically in apoE-/- mice: electrocautery of the right kidney at 8 weeks of age and nephrectomy (NX) of the left one 2 weeks later. Control mice were sham-operated. Two weeks after NX, renal functions were detected in the uremic and control mice to evaluate the efficiency of the model. After 10 weeks of NX, blood samples were taken to determine serum biochemical parameters, and aortic root was collected for frozen sections to investigate the lesion features of AS. Results Two weeks after NX, renal functions declined significantly in the uremic mice compared with the control ones, and remained stable 8 weeks later either in males or in females. Ten weeks after NX, serum levels of TCH, TG and LDL-C were dramatically higher in the uremic mice than in the controls, whereas no differences in serum HDL-C or glucose concentration were found between the two groups. Aortic root plaque relative area increased significantly in the uremic mice compared with the controls either in males or in females; more-over, the lesion area was larger in female mice than in male ones. Conclusion We established a uremic apoE-/- mouse model successfully, and this model is characterized by accelerated atherogenesis which is associated with an increase in serum lipid profile. This experimental model can be a useful tool to study the pathogenesis and therapeutic strategies of uremic AS.

Objective To assess the reliability and validity of the Chinese version of the neuropsychiatric inventory (CNPI). Methods The CNPI was administered to 219 caregivers of patients with Alzheimer's disease (AD). Each caregiver was retested 4 weeks after initial testing. Results The Cronbach a coefficient of the total symptom scale was 0.69. The Cronbach α coefficient of the total caregiver distress subscale was 0.72. The Cronbach α coefficient of the entire inventory was 0. 82. The test-retest coefficients ranged from 0.66 to 0.98 (P < 0.01). Principal axis factoring analysis of the symptom subscale yielded a five-factor solution which contributed to 67.0% of the cumulative variance. Factor 1, which included aberrant motor behavior, hallucinations, delusion and irritability had the most significant contribution to the cumulative variance. Principal axis factoring analysis of the caregiver distress subscale also yielded a five-factor solution which contributed to 70.2% of the cumulative variance. Factor 1, which included depression, delusion, sleep/night behavior, aberrant motor behavior, and irritability had the most significant contribution to the cumulative variance. Conclusion This Chinese version of NPI is a reliable and valid tool for measuring neuropsychiatric disturbances in patients with AD.

Objective To assess the risk factors of the in-hospital mortality of acute type A aortic dissection after operation. Method From January 2003 to June 2008,185 patients, 144 males and 41 females, with acute type A aortic dissection operated on were enrolled. The average age of patients was (49.46 ± 11.04 ) years old.The patients' demographics, history, clinical features, and some laboratory examinations were reviewed. Univariate and multivariate analysis followed by logistic regression analysis were carried out to identify the predictors of inhospital mortality. Results The in-hospital mortality rate was 9.1%. The results of univariate and multivariate analyses as follows: pre-operation positive neurological symptom (Univariate OR = 5.084,95%CI:1.792 -14.426, P = 0.002; Multivariate OR = 5.538,95%CI: 1.834 - 16.721, P = 0.002, respectively), hypotension (Univariate OR = 6.986,95%CI:1.510- 32.323,P =0.013; multivariate OR = 1.998,95%CI:0.315-12.679,P = 0.463, respectively) and renal failure (Univariate OR = 3.594,95%CI:1.237 - 10.438,P =0.019; Multivariate OR = 3.254,95%CI:1.034- 10.242, P= 0.044, respectively). Conclusions There are two predictors, pre-operation positive neurological symptom and renal failure, of pre-hospital mortality found in current analyses. Our results may improve the regimen made by cardiac surgeons and emergency doctors so as to help patients and their relatives to make correct decision.
