Objective:To study the mechanism of anti-proliferative effect of lupeol on highly metastatic human hepatocellular car-cinoma HCCLM3 cells. Methods:CCK-8 assay was performed to evaluate the effects of lupeol at different concentration on cell viability in 12-48 h. Caspase inhibitors were used to identify the subtypes of caspases activated during lupeol-induced cell death. The effects of lupeol on the mRNA expression of caspase family and Bcl-2 related genes were detected by real-time PCR. The effects of lupeol on HC-CLM3 cell phase distribution were investigated by flow cytometry. Results:Compared with the control group, lupeol could inhibit HC-CLM3 cell proliferation in a concentration-dependent manner with IC50 of 93 μmol·L-1 in 24h. The number of HCCLM3 cells in the period of G2/M was increased by 1-fold when the lupeol concentration was within 60-100 μmol·L-1 . Lupeol could activate the path-way of caspase, and the mRNA expression of caspase-3 was elevated by 50%-150% when compared with that in the control group. Mo-reover, the mRNA expression of p53 and Bax were increased above 1-fold by lupeol at 100 μmol·L-1 , and the Bcl-2 and PARP ex-pression were significantly suppressed by lupeol at 60-100 μmol·L-1(P<0. 05 or P<0. 01). Conclusion:The results indicate that lupeol has anti-proliferative effect on the liver cancer cells, which is beneficial to the prevention and treatment of liver cancer.

Objective:To discuss the results interpretation and clinical significance of Acinetobacter Baumanni ( AB) positive spu-tum samples .Methods:The anti-infection treatment of one patient with lung infection after colon cancer surgery in ICU was analyzed , and the results interpretation and clinical significance of AB positive sputum samples were discussed .Results:Although the culture re-sults of sputum samples were positive , the quality of sputum samples was low and the credibility was poor .The possibility of multiple drug resistance AB ( XDR-AB) screened by antibiotics selective stress was small .Meanwhile, the clinical infection symptoms were mild, and the treatment with imipenem was effective .Although the patient had high risk factors for the colonization of Baumanni infec-tion, XDR-AB was not a pathogen .Conclusion:When respiratory samples are AB positive , the quality of samples should be evaluated by smear results firstly , especially the existence of white blood cell phagocytosis or accompanying should be paid attention to , and then the possibility of AB screened by antibiotics selective stress and high risk factors for colonization should be analyzed .Finally, combined with the clinical symptoms of patients and the treatment efficacy before drug sensitivity tests , whether XDR-AB is pathogenic bacteria should be judged , and then the corresponding anti-infection treatment plan should be determined .

Objective To evaluate the feasibility of using stroke volume variation (SVV) as the left ventricular preload to draw the cardiac function curve.Methods Twenty-seven patients of both sexes,aged 18-64 yr,with body mass index of 18-30 kg/m2,of American Society of Anesthesiologists physical status Ⅱ (New York Heart Association Ⅱ),with abnormal cardiac function,scheduled for elective offpany coronary artery byp grafting,were enrolled in this study.Twenty-five patients,aged 18-64 yr,with body mass index of 18-30 kg/m2,of American Society of Anesthesiologists physical status Ⅰ (New York Heart Association Ⅰ),with normal cardiac function,scheduled for elective non-cardiac surgery,were also enrolled in this study.SVV and SV were monitored by using a FloTrac/VigileoTM system.The patients were in the supine position from the end of anesthesia induction to the beginning of surgery.After the hemodynamics was kept stable for 5 min,SVV and SV were recorded.6% hydroxyethyl starch 130/0.4 500 ml was intravenously infused over 20 min.SVV and SV were recorded after volume expansion.Spearman rank-order correlation was used to analyze the relationship between SVV and SV.The quadratic regression analysis was used to draw the SVV-SV curve,and the SVV-SV curve was compared with the Frank-Starling curve.Results Compared with the value before volume expansion,SVV and HR were significantly decreased,and SV was increased after volume expansion in the patients with normal cardiac function,and SVV was decreased after volume expansion in the patients with abnormal cardiac function (P<0.01).SVV was negatively correlated with SV in the patients with normal cardiac function,and r=-0.467 (P<0.05).SVV was negatively correlated with SV in the patients with abnormal cardiac function,and r=-0.378 (P<0.05).The mirror symmetry was found between the SVV-SV curve in the patients with normal cardiac function and the normal Frank-Starling curve,and the general trend was close.The symmetry was not detected between the SVV-SV curve in the patients with abnormal cardiac function and the Frank-Starling curve in the patients with decreased myocardial contractility,and the general trend was not close.Conclusion For the patients with normal cardiac function,SVV can be used as the left ventricular preload to draw the cardiac function curve.

The abdominal visceral fat content in obese SD rats induced by high fat diet for 10 weeks was significantly higher than that in control group [(26±6 vs 13±3)g,P<0.01] ,along with increased CRP mRNA expression in abdominal visceral fat (0.901±0.085 vs O. 402±0.036, P<0.01). As compared with normal control group, in the high fat group the concentrations of CRP in portal vein [(743.8±95.8 vs 558.3 ±118.3) mg/L, P<0.01] and peripheral vein[(596.3±38.9 vs 485.8±30.2) mg/L,P<0. 05] were higher. The concentration of CRP in portal vein was significantly higher than that in peripheral vein in high fat diet group(P<0.01) ,but this was not evident in control group. These results suggest that the increased CRP expression in visceral adipose tissue may partially account for the elevation of serum CRP in obesity.

Objective To summarize the characteristics of nosocomial infections in the patients treated in intensive care unit (ICU).Methods The incidence of nosocomial infections was monitored in ICU from March 2012 to August 2012.The incidence rate of infection was adjusted with Average Severity of Illness Score (ASIS)score and analyzed in relation to three invasive pro-cedures.Pathogen distribution of nosocomial infections in ICU was also analyzed.Results Nosocomial infection was identified in 357 of the 3 700 ICU patients (9.65%).The overall daily infection rate was 30.34‰,specifically,49.10‰ for ventilator asso-ciated pneumonia (VAP),13.86‰ for catheter-related bloodstream infections (CRBSI),and 1.09‰ for catheter-associated urinary tract infections (CAUTI).Of the 688 bacterial isolates,gram negative bacteria accounted for 82.70%.The top three bacterial species were Acinetobacter baumanii ,Pseudomonas aeruginosa ,and Klebsiella pneumoniae .Conclusions ICU is the focus for surveillance of nosocomial infections.Objective investigation is critical for nosocomial infection surveillance.

Objective To explore the value of shear wave elastrography (SWE) in diagnosis of prostate cancer.Methods SWE quantitative elastography was preformed in 55 patients with suspected prostate cancer,to obtain the elastic modulus (mean,maximum).Each patient underwent sonography-guided prostatic biopsy on the same day.With the pathologic results as reference,ROC curves were used to assess diagnostic performance.Results ①Pathological tests showed that 39 lesions were benign(hyperplasia) and 16 lesions were malignant.The mean elasticity value of benign lesions was (39.04 ± 8.22) kPa,and the maximum value was (54.10 ± 9.18)kPa,whereas of malignant ones were (53.31 ± 3.92)kPa and (68.71 ±2.57)kPa,respectively (P <0.05).② The area under the ROC curve (AZ) of the maximum and mean elasticity value was 0.951 and 0.944.Taking 48.07 kPa as the threshold of the mean elasticity value,the sensitivity was 91.8% and the specificity was 89.7%.Then taking 65.50 kPa as the threshold of the maximum elasticity value,the sensitivity was 92.1% and the specificity was 87.5%.Conclusions SWE is helpful to diagnose and differentiate prostate diseases by measuring elastic modulus.

Objective To study the characteristics of ? cell function change and to explore the predictive value of glutamic acid decarboxylase (GAD)-Ab and other factors for ? cell function in the patients with latent autoimmune diabetes of adults (LADA). Methods Sixteen LADA patients (positive GAD-Ab) and 24 type 2 diabetic patients (negative GAD-Ab) were followed-up at 0, 6th, 12th, 30th, 36th, 42th and 48th months respectively. Their fasting and postprandial 2h C-peptide and glycemic control were measured. GAD-Ab was determined by radioimmunoprecipitation assay and C-peptide by RIA. Results Decreased fasting C peptide (FCP) levels (Month 30, 36, 42, 48 compared with Month 0, P
