Prostate cancer is one of the most common malignant tumors in the male urinary system as well as the second leading cause of cancer death in men. Prostate specific antigen (PSA) screening is the main method for the early diagnosis of prostate cancer, but has a low specificity for its detection. In recent years, a variety of tumor markers with high sensitivity and specificity have been found. This review focuses on some of the more promising tumor biomarkers such as prostate cancer antigen 3, early prostate cancer antigen, prostate-specific membrane antigen, alpha-methylacyl-CoA racemase, and vascular endothelial growth factor.

Near infrared spectra in the range of 11501.4 ～ 6047.7 cm- 1 were used for simultaneously determination four oestrogens and progestogens: estradiol, estriol, medroxyprogesterone acetate and estrone. Constant offset elimination data pretreatment and partial least square regression method were used to resolve the spectra overlap of the four substancesas well as the tetrahydrofuran solvent. 100 samples were taken as the calibration set getting a correlation coefficient of 0. 99. The relative deviations for prediction samples were < 5 %. Some measuring factors influencing regressive accuracy like moistrue, temperature and dissolvent were discussed.

Objective To investigate the clinical outcome before and immediately after implementation of fast track surgery protocol on patients with gastric cancer.Methods One hundred and thirty patients with gastric cancer in our hospital underwent an elective,uncomplicated,open gastric surgery before (Traditional care group,n =65) and immediately after implementing fast track surgery (Fast track surgery group,n =65).Postoperative food and fluid intake,mobilization,length of hospital stay,and clinical outcome were recorded and analysed,and a interview-based assessment was performed on days 14 and 30 postoperatively.Results Patients implemented fast track surgery were associated with a significantly earlier resumption of mobilization and oral fluids and normal diet,shorter duration of intravenous infusion compared with traditional care patients 0.3 (0-1) d vs 3.3 (2-4) d,0.2(0-1) d vs 3.5(3-4) d,3.3(3-4) d vs 5.6(5-6) d,3.4(3-4) d vs 5.2(5-6) d; P=0.000,respectively.Postoperative hospital stay was also shorter in fast track surgery group 6.6 (6-8) d vs 8.6 (8-9) d ; P =0.000.Instrumental activities of daily living decreased in both groups on day 14,but significantly more in the traditional care group,despite having a higher preoperative instrumental activities of daily living level compared with the fast track surgery group 5.0 (3-6) vs 3.0 (3-5),4.0 (3-6) vs 3.0 (3-5) ; P =0.000,respectively.Preoperative fatigue score was not different between two groups,but the fatigue score was significantly increased on day 14,and returned to normal value on day 30 in the traditional care group 2.0 (1-5) vs 3.0 (1-5),2.0(1-5) vs 2.0(1-6) ; P =0.005,P =0.065.Total length of sleep on day 14 was increased significantly in the traditional care group,but not changed in the fast track surgery group compared with preoperative value 9.0 (6-11) vs 8.0(5-10) h,8.0(5-11) vs 8.0(6-10) h; P=0.000,P=0.327.Conclusions A fast track surgery protocol can lessen postoperative stress reactions and enhance recovery for patients with gastric cancer undergoing an elective,uncomplicated,open resection.

AIM:To investigate the role of heme oxygenase (HO) in AngⅡ induced proliferation and hypertrophy of cultured vascular smooth muscle cells. METHODS:(1) Western blotting analysis was carried out to detect protein level of HO-1 in the tissues. (2) [3H]-TdR,[3H]-leucine incorporation was measured in cultured vascular smooth muscle cells. (3) 2',7'-dichlorofluorescin diacetate (DCFH-DA) as an index was used to determine the cellular reactive oxygen species (ROS) level. RESULTS:(1) No significant difference in HO-1 protein expression level between AngⅡ-stimulated and control groups was observed,but HO-1 protein level in Hemin-induced group was higher than that in other two groups (P

AIM: To investigate the effect of heme oxygenase /carbon monoxide(HO/CO) system on the pathogenesis of hypertension and effect of Heme-L- Lysinate(HLL), Zine protoporphyrin-IX(ZnPPIX) on vascular tension in a two kidney one-clip model. METHODS: The changes in mean arterial pressure and heart rate as well as phenylephrine(PHE)-induced contraction in isolated aortic rings of HLL, ZnPPIX- treated rats were examined after intraperitoneal administration of HLL and carbon monoxide( CO). RESULTS: (1) Injection of exogenous CO resulted in a significant decrease in mean arterial pressure in Sham and 2K1C groups(P

Objective To investigate the effect of radiotherapy combined with interventional therapy on the changes of vascular endothelial growth factor (VEGF) in patients with advanced cervical cancer.Methods 62 cases of cervical cancer collected in the first people’s hospital of jingzhou city during January 2009 to February 2014 were randomly divided into two groups.The patients in group A were treated with radiotherapy, and the patients in group B were treated with radiotherapy combined with interventional therapy.The level of vascular endothelial growth factor in two groups after treatment was measured by enzyme-linked immunoassay.Results The level of vascular endothelial growth factor of group A was ( 241.77 ±85.86 )μg/L, significantly higher than ( 124.66 ±65.86 )μg/L of group B.The level of vascular endothelial growth factor was related with cervical deterioration degree, tumor stage and lymph nodes metastasis (P<0.05),not with the patient’s age, and the size of the tumors.The level of vascular endothelial growth can reflect the clinical efficacy of patients after therapy (P<0.05).Conclusion Vascular endothelial growth factor level has a close relationship with the degree of deterioration of cervical cancer, tumor staging, lymph node metastasis and the curative effect after the interventional therapy.

Objective To assess the role and its tecnhique superiority of 64-slice spiral CT angiography(CTA) in lower limb arterial diseases.Methods MSCT studies in 33 cases suspected diseases of lower limb arteries was performed,the helical scans covered the extent of renal artery to the artery of the lower extremity.3D reconstruction of vessel was done in Wizard workstation.The manifestations of MSCTA were compared with that of conventional angiography . Results Of the 693 segments of arteria , 683 were assessable on both DSA and CTA.Using the DSA images as the standard reference,the sensitivity,specificity and accuracy of CTA were 97.6%(95% CI,94.9%~100.7%),98.9%(95% CI,98.0%~99.8%),98.7%(95% CI,97.9%~99.5%)in detecting the segments occluded . With the regard the detection of segments that had more than moderate stenosis , the sensitivity , specificity and accuracy of MIP were 98.9% ( 95% CI , 97.4%~100.4%),99.4%( 95% CI, 98.7%~100.1%) and 99.3%(95% CI, 92.4%~99.9%).Conclusion In assessment of diseases of lower limb arteries with 64-slice spiral CT angiography is equal to DSA basically, it is a highly accurate and non-invasive angiography in diagnosing arterial diseases of the lower extremities.

Objective To investigate the effects of different thickness of cell culture dishes on fluorescent image with confocal microscope.Methods The fluorescent staining experiments of live cells and fixed cells were used to determine the differences among three dishes with different thickness coverslips of 0.085～0.13 mm,0.13～0.16 mm and 0.16～0.19 mm,while the cell appearance,fluorescence lightness and mean of fluorescence intensity were studied with confocal microscope.Results Demonstrated by the results of cytoskeleton staining experiments,the dish with 0.13～0.16 mm thickness coverslip was the best choice for confocal microscope,the dish with 0.16～0.19 mm thickness coverslip was the second one,the dish with 0.16～0.19 mmthickness coverslip was the last one.ConclusionThe dish with 0.13～0.16 mm thickness coverslip is the best choice for confocal microscope.On this type of dish,the cytoskeleton is unfolding and clear after staining.The intensity of fluorescence is the strongest,and the imaging effect is the best.
