Objective To develop a sensitive,specific, simple and rapid quantitative real-time PCR (Q-PCR) assay for detection of Staphylococcus aureus with SmartCycler.Methods According to the nuc gene sequences specific to S.aureus, a pair of primers and one TaqMan probe were designed. An internal amplification control (IAC) which is a chimeric double-stranded DNA constructed from a fragment of the Listeria monocytogenes hly gene flanked by the nuc-specific target sequences was added to the reaction system. This IAC was detected using a second TaqMan probe labeled with a different fluorophore. The performance of the nuc-IAC Q-PCR was evaluated using artificially contaminated drinking water and commercial UTH whole milk samples spiked with ATCC 6538.Results The nuc-IAC assay could be used reliably for detection with a sensitivity of 5 copies of linear plasmid DNA per reaction, 10 fg of genomic DNA in 62.5% of the reactions or 50 cfu/ml S.aureus cells with 50% probability. The quantification was linear (r~2≥0.998) over a 6-log dynamic range, with a PCR efficiency over 0.967. The 5×10~2 CFU per 25 ml mimic sample of drinking water or milk could be detected by this assay consistently and quantifiably.Conclusion The nuc-IAC Q-PCR assay for S.aureus is developed. It could not only be applied for the quantitative detection of S.aureus, but also prevent the false negatives and underestimations of contamination loads due to PCR failure.

Objective To assess the influence of laparoscopic sleeve gastrectomy (LSG) on the nutritional status in patients with obesity.Methods From August 2014 to July 2015, 24 obese patients underwent LSG in Dongfang Hospital Affiliated to Tongji University.Weight and nutritional status of these patients were measured pre-operatively and 3, 6, and 12 months after surgery.Results The mean body weight of the 24 obesity patients was (81.94±21.39) kg, (78.83±24.49) kg, (62.67±10.79) kg 3, 6, and 12 months after surgery, respectively, which were significantly lower than the preoperative body weight [(99.02±23.92)kg] (P=0.004).The serum levels of albumin, hemoglobin, and trace elements (including calcium, iron, zinc, magnesium, and copper) showed no significant change after surgery (all P>0.05).Plasma vitamin D[25(OH)D] increased significantly from (13.1±4.1)μg/L preoperatively to (19.8±5.3)μg/L 12 months after surgery (P=0.031).Folic acid was (6.2±3.9)μg/L before LSG and significantly increased to (14.2±9.2) μg/L 3 months later surgery (P=0.009);the folic acid level gradually decreased 6 and 12 months after LSG but was still higher than the preoperative level.Conclusion Vitamin D deficiency is present in obese patients before LSG.After surgery, while the serum albumin and trace elements have no obvious change, the vitamin D and folic acid levels remarkably increase.

Objective To investigate the effects of Dihuangyinzi(DHYZ) on behaviors and RAGE/p38 pathway in APP/PS1 mice.MethodTwenty APP/PS1 dementia mice were randomly divided into model group(n=10) and Chinese medicine group(n=10).The blank group was C57 BL/6 J normal mouse(n=10).The mice in Chinese medicine group were intragastric administration with DHYZ (9.75 g·kg-1·d-1).The mice in model group and blank group were treated with distilled water.After 30 days,the abilities of learning and memory of mice were detected by Morris water maze.The expression of amyloid-beta1-42(Aβ1-42) in the hippocampus and cortex was detected by immunohistochemistry.Reactive oxygen species of brain tissue were detected by DCFH-DA Methods in the brain of APP/PS1 mice.Gene expression level of receptor for advanced glycation end products(RAGE) was measured by real-time polymerase chain reaction (RT-PCR) in the cortex and hippocampus of APP/PS1 mice.The expression of phospho-mitogen-activated protein kinases (p38) was analyzed with Western blot and immunofluorescence analysis in the cortex and hippocampus of APP/PS1 mice.Results Behavioral Results showed that DHYZ significantly increased the distance((23.088±7.083)cm) and residence time((1.961±1.230)s)of effective area in Morris water maze on the fifth day(P<0.05,P<0.01)and remarkably increased the number of effective area crossings((1.607±0.405) times) and plats((0.893±0.283) times) in Morris water maze on the fifth day(P<0.01,P<0.05).DHYZ also significantly reduced the intracelluar ROS level(122.611±7.630) in the brain(P<0.01),and DHYZ could depress the expression of RAGE(1.467±0.081,7.983±0.136) and phosphorylation of p38 (0.376±0.026,0.538±0.016)in the cortex and hippocampus of APP/PS1 mice(P<0.01,P<0.05).Conclusions The Results demonstrate that DHYZ can partly improve memory impairment of APP/PS1 mice by the inhibition of RAGE/p38 pathway.

Objective:To investigate the effect of intermittent hormonal therapy(IHT) for patients with different stage/grade prostate cancer(PCa).Methods:The number of cycles and the duration of ON/OFF therapy for 45 PCa patients receiving IHT were observed.Maximal androgen blockade(MAB) the-rapies were used for six to nine months,and then stopped until the serum prostate specific antigen(PSA) was decreased below 0.2 ?g/L,which lasted for three months.It was decided whether MAB went on according to the level of PSA.Results:The average follow-up time was 40.7?13.4 months.Forty-one patients started the second cycle of treatment,of whom,8 became androgen-independent and 7 were at T3-4M0 or M1 stages and the Gleason scores were above 8.Sixteen patients entered the third cycle,of whom,14 were at lower than stage Ⅲ and 13 had the Gleason scores below 7.From the first to the fourth courses of treatment,the average intervals were 8.7?5.4(47.1%),8.4?4.9(49.3%),7.0?3.4(43.7%),and 3.7?0.6(42.5%)months respectively.Five patients developed bone metastasis.No one died up to now.According to the evaluation criteria,patients were divided into tolerance(n=16) and intolerance groups(n=29).Compared with the intolerance group,the patients who tolerated the treatment well had lower Gleason scores(P=0.002),lower PSA levels(P=0.053) and lower tumor stages(P=0.001).There was no evidence that age,lymph node metastasis,bone metastasis and the state of recurrence were associated with an increased risk of the outcome.Non-conditional Logistic regression analysis showed that the proportion of patients at stage Ⅳ was the only independent risk factor for the tolerance of the treatment(OR=12.113,95%CI 1.330-110.312,P=0.027).Conclusion:Intermittent hormonal therapy is more effective and proper for the patient with highly differentiated tumor and at lower stages(≤Ⅲ).The patients who progressed to hormone-independence are mostly at stage Ⅳ with poorly differentiated tumor.Intermittent hormone therapy could be more adaptive for the patients at lower than stage Ⅲ.

Background and purpose:The chemokine,CXCL12 and its receptor,CXCR4,have recently been shown to play an important role in the metastasis of several kinds of carcinoma. It also has been demonstrated that VEGF regulates both the expression of CXCR4 and invasiveness in cancer cell. Our aim was to study the expression of CXCR4,VEGF in osteosarcoma and the correlation between these two factors and distant metastasis. Methods: The immunohistochemical staining SP method was used to detect the expression of CXCR4 and VEGF in 56 cases of osteosarcoma. We analyzed the correlation between the expression of CXCR4 and VEGF,and the correlation between the expression of CXCR4,VEGF and clinical stage,the level of ALP. The patients were followed up for 2 years. Results:There was signifi cant correlation between the expression of CXCR4 and VEGF in 56 cases(r=5.678,P=0.02). Univariate analysis showed a signifi cant correlation between the expression of CXCR4,VEGF and clinical tumor stage(P=0.026),and no correlation between the expression of these two factors and age,sex and serum ALP level. 31 cases had metastasis in two years in a total of 56 follow-up cases,and the expression of CXCR4 and VEGF was associate with metastasis(P=0.018 and P=0.022,respectively). Conclusion:VEGF can upregulate tumor angiogenesis and promote tumor metastasis to specific organ by increasing expression of CXCR4.The increasing expression of CXCR4 and VEGF is useful to predict metastasis and prognosis of osteosarcoma.

Objective To evaluate the effects of impaired glucose tolerance (IGT) on ventricular remodeling. Methods Parameters of every subject including left ventricular mass ( LVM), left ventricular mass index (LVMI), E/A ratio, 75 g oral glucose tolerance test (OGTT), ambulatory blood pressure monitoring(ABPM) data including 24-hour mean systolic blood pressure(mSBP) and 24-hour mean diastolic blood pressure(mDBP) were collected. Then the relationship of IGT and myocardial remodeling related parameters were analyzed. Results The rate of diastolic dysfunction was higher in the IGT combined with hypertensive group(74% ) compared with the hypertensive group( 39% )( x2 = 6. 5, P ＜ 0. 05 ). The rate of diastolic dysfunction was higher in the IGT group( 34% ) compared with the normal group( 10% ) (x2 = 5.2,P ＜0. 05). The rate of Left Ventricular Hypertrophy (LVH)in the IGT combined with hypertensive group (24%) was higher than the other three groups (Hypertension group 7%, IGT group 0, Normal group 0) (x2 =4.561,P ＜0.05), and there was no significance between the rest three groups (P ＞0.05).Stepwise multiple regression showed age and 2 Hours' Postprandial Blood Glucose were independent risk factors of E/A ratio. Conclusions These results suggested that IGT is a possible contributor to left ventricular hypertrophy and diastolic dysfunction, and is one of the histopathology of left ventricular remodeling.
