0.05). Conclusions The detections of survivin and MCM5 in urine sediments are sensitive and non-invasive diagnostic tests for bladder cancer.The combination of survivin and MCM5 may be more effective than either of them alone.

BACKGROUND: Animal experiments demonstrated that adding ultraviolet blood irradiation and oxygenation (UBIO) in cardioplegic solutions has myocardial protection during cardiopulmonary bypass (CPB).OBJECTIVE: To investigate the myocardial protective effect of UBIO as cardiac arresting solution in the process of CPB in old patients undergoing valve replacement.DESIGN, TIME AND SETTING: The randomized controlled trial of biochemistry level was performed at Department of Cardiac Surgery, Guizhou Provincial People's Hospital, from October 2006 to April 2008.PARTICIPANTS: A total of 46 old patients scheduled for heart valve replacement were randomly divided into test group and control group, with 23 patients in each group.METHODS: The test group was infuoed with the UBIO blood as a cardiac arresting solution via the ascending aorta. The UBIO blood accumulated from the subclavian vein (10 mL/kg) was heparinized and dealt with the ultraviolet irradiation (wave length 240-300 nm) and oxygenation. And then it was infused for the first antegrade coronary perfusion when the ascending aorta was cross-clamped, when the UBIO blood was produced, the equivalent quantitative saline was infused from another vein. The 4:1 cold oxygenated blood hyperhalemia cardioplegia was perfused and then maintained for 30 minutes. The control group was the same as the test group except that the cardiac arresting solution presented without the 4:1 cold oxygenated blood.MAIN OUTCOME MEASURES: Blood samples were withdrawn from coronary venous sinus before cross-clamping and at minutes 5 and 10 after aorta declamping, to measure the levels of superoxide dismutase (SOD) and the content of malondialdehyde (MDA). Before the beginning of CPB, and at hours 4, 24, and 48 after the end of CPB, venous blood was drawn to test the serum cardiac troponin I(cTnI) and creatine kinase isozyme (CK-MB).RESULTS: MDA levels of plasma were less in the test group than that of the control group after aorta declamping (P < 0.05),while the SOD activity was obvious greater than the control group (P < 0.05). At hours 4-48 after CPB, CK-MB and cTnl levels were lower in the test group than the control group (P< 0.05).CONCLUSION: Antegrade coronary first perfusion with UBIO during CPB has evident cardiac protective in old patients undergoing valve replacement by elevating SOD activity, decreasing MDA level, relieving myocardial reperfusion injury, as well as decreasing myocardial damage markers levels.

BACKGROUND:Traditionally, forced expiratory volume in one second (FEV1) was used to evaluate exercise response of patients with asthma; however, patients obviously had panting after exercise, so FEV1 was affected commonly. Impulse oscillometry (IOS) is a new technique for measuring respiratory impedance that do not require maximal inspiration and forced expiration.OBJECTIVE: To study airway resistance with IOS before and after exercise in healthy and asthmatic patients and investigate the significance of exercise excitation and IOS assessment.DESIGN: Synchronically non-randomized case contrast study.SETTING: Department of Respiratory Medicine, East Hospital Affiliated to Tongji University.PARTICIPANTS: A total of 14 male patients with bronchial asthma who were regarded as the asthmatic group were selected from Department of Respiratory Medicine of Shanghai East Hospital from January to October 2006. They were in a clinical stationary phase. Another 14 male healthy subjects were selected as the control group and ages of all subjects ranged from 29 to 50 years. All subjects provided the confirmed consent.METHODS: IOS was used to measure basic value of respiratory resistance, and then subjects underwent exercise challenge. Nose of subjects was clipped breathing through mouth. Within 3-4 minutes, heart rate was increased to 90% and maintained for 6 minutes during challenge. Respiratory resistance was repeatedly measured at 1, 5, 10, 15 and 20 minutes after exercise, including airway hyperresponse (AHR), total respiratory resistance, central resistance, peripheral resistance and resonance frequency at 5, 20 and 35 Hz of pulse frequency, elasrtic resistance and inertia resistance (X5 and X35) at 5 and 10 Hz of pulse frequency. In addition, difference of AHR at 5 and 35 Hz was calculated, and change ratios of both Rcentral and Rperipheral were calculated as (highest value after exercise-baseline value)/baseline value × 100%.MAIN OUTCOME MEASURES: Basic value of respiratory resistance by using IOS and exercise challenge test.RESULTS: All 14 patients with bronchial asthma and 14 healthy subjects were involved in the final analysis. Peripheral resistance (Rperiphera) was significantly higher than central resistance (Rcentral) in asthmatic patients (P ＜ 0.01). The maximal increase of respiratory impedance occurred from 5 minutes to 10 minutes after exercise in asthmatics. Resonance frequency (Fres) of asthmatics before and after exercise was significantly increased than that of controls (P ＜ 0.01).Change ratios of Fres from asthmatics were higher than that from control group (P ＜ 0.01). After challenge, R5, R5-R20,Zrespir and X5 from asthmatics changed significantly than that from controls (P ＜ 0.01). The increment change value of After exercise Zrespir increased significantly, because obstruction of small bronchi during expiration and impedance increased abruptly. Air trapping was expressed in VT-Zrespir graph in 57.1% patients. There was no difference in the VT-Zrespir graph of controls before and after exercise.CONCLUSION: The main site of airflow obstruction was in small airways in asthmatics after exercise challenge. The general acceptance of IOS method was good among the asthmatic patients. The airway response of exercise challenge may be assessed more accurately with IOS that do not require a maximal inspiration and forced expiration.

Objective To investigate the influence of motor impersistence on functional recovery and prog- nosis of patients with left hemiplegia. Methods A total of 64 in-patients with left side hemiplegia who were able to understand the oral instructions were assigned into a motor impersistence group (n = 31 ) and a control group (n = 34) , respectively, according to the assessment with Scale of Motor Impersistence developed by Joynt. Both groups were comparable in terms of the basic clinical characteristic and motor function of patients except motor impersis- tence. The conventional rehabilitation training programs were adopted for all patients in this study. Brunnstrom func- tional category, Ueda Satoshi hemiplegic finger function assessment scale, upper limb function assessment scale, Berg balance scale, Functional ambulatory category, Modified Barthel Index were employed to evaluate the subjects before and after 1 and 2 months of treatment, with regard to the motor function of their upper limbs, walking ability, activities of daily living performance and balance ability. Results After 1 month of treatment, the patients in the M1 group were significantly improved with regard to the motor function of upper limbs, hand function, standing ba- lance and activity of daily living performance( P0.05 ) , while those in the control group were improved with all the parameters except the lower limb function. After 2 months of treatment, patients in both groups were all significantly improved ( P

Objective To investigate the feasibility of high?resolution microendoscopy( HRME) im?aging for animal gastrointestinal mucosa. Methods Mucosal tissues were harvested from the stomach, small intestine, and large intestine of Japanese big?ear white rabbits. The effects of HRME imaging of different lo?cations such as the gastric antrum and fundus, small intestine and large intestine were observed, and those of different exposure time were compared.Accuracy of HRME imaging was compared with pathology. Results The specific tissues of the gastrointestinal mucosa could be clearly distinguished from the HRME images. In the superficial layer of the fundic mucosa, numerous closely arranged glands as well as oval or elongated branched openings of the gastric pits and linear peripheral cracks were visible;the nuclei were arranged reg?ularly. In the superficial layer of the antral mucosa, irregular or tubular openings of the gastric pits and cracked glandular cavities were visible, with the cells surrounding the gastric pits regularly arranged and the nuclei small and densely distributed. In the superficial layer of the small intestine mucosa, stereoscopic thick?finger?shaped villi cluster was visible. The intervillous spaces were crack?like, and the surface was cov?ered by regularly arranged reflective, absorptive cells. In the superficial layer of the large intestine mucosa, many regularly arranged daisy?like round crypts of uniform size, as well as reflective, goblet cells surrounding the crypt and the interval space between crypts were visible. When the exposure time increased, the nuclei became brighter. An excellent correlation was noted between the results of histologic examination and those obtained by using HRME. Conclusion HRME can produce accurate images of the animal gastro?intestinal mucosae and may be a novel technique for further studies of human gastrointestinal pathology.
