Objective To explore the nonenhanced CT images,mechanism and clinical application of perinephric edema associated with acute ureterolithiasis.Methods Nonenhanced CT images in 73 patients with acute ureterolithiasis were retrospectively reviewed.Results Of 73 patients with acute ureterolithiasis,eight had no perinephric edema at CT,41 had limited edema and 24 had extensive edema.Conclusion Perinephric edema is a important CT finding of ureteral obstruction in patients with acute ureterolithiasis.

Objective To investigate the expression pattern of Th1 and Th2 in patients with pulmonary tuberculosis including sputum positive pulmonary tuberculosis and coinfection with human immunodeficiency viruses(HIV), and its relation to disease severity.Methods The expression pattern of CD4+T lymphocytes, Th1 and Th2 cells in peripheral blood samples from sputum positive pulmonary tuberculosis patients, coinfection with HIV patients and healthy controls were studied by flow cytometry.Results The expression of CD4+ T lymphocytes and Th1 cells in sputum positive pulmonary tuberculosis patients were significantly lower than that in healthy group(31.22?9.80)%,(9.78?3.09)% vs (43.77?10.78)%,(25.26?4.73)%; The expression of Th2 cells in culture positive pulmonary tuberculosis patients was significantly higher than that in healthy group(18.65?3.49)% vs(10.15?2.60)%; The Th2 level in severe pulmonary tuberculosis patients was significantly higher than that in the medium and mild patients(21.70?2.67)% vs (14.87?1.66)% ,(17.48?2.06)%, while the CD4+T lymphocytes and Th1 levels were significantly lower; The CD4+ T lymphocytes and Th2 cells levels in pulmonary tuberculosis patients coinfection with HIV were lower than that in tuberculosis patients without HIV coinfection(21.88?3.71)%,(8.79?2.28)% vs (31.22?9.80)%,(18.65?3.49)%.Compared with the healthy group, Th1 cells level in pulmonary tuberculosis patients with or without coinfection of HIV were lower(25.21?4.73)% vs (9.39?2.65)%,(9.78?3.09)%.Conclusion Patients with sputum positive pulmonary tuberculosis showed lower expression of Th1 and higher expression of Th2,This profile was correlated with disease severity.Patients with pulmonary tuberculosis and HIV coinfection showed both of lower expression of Th1 without enhancement of the type 2 response.

In this paper, the structure, operational principle, clinical application of a novel pulse therapeutic apparatus are introduced. Controlled though a SCM, the apparatus can output biphasic constant current and special pulses for electrostimulation.With the electrode impedance measured automatically, the apparatus can be applied to the treatment and rehabilitation of several diseases of gynecology & Obstetrics.

This paper introduces the structure and principle of a novel low-frequency electronic pulse therapeutic apparatus. Based on a novel single -chip microprocessor, the device can generate multiple special pulse signals and output bi -directional electronic pulse. At the same time, it can detect the impedance automatically and thus its security is improved.

The latest reports showed that kidney secrets a new type protein:renalase,a novel flavin adenine dinucleotide-dependent(FAD-dependent)amine oxidase which is secreted into the blood by the kidney and regulates heart function and blood pressure by metabolizing catecholamines.Kidney disease is associated with cardiovascular disease,so people pay more and more attentions to renalase.This article will introduce the structure and mechanism of renalase,and propose its future.

Objective To study the risk factors of patients with atherosclerotic renal artery stenosis (ARAS) and the relation with renal function.Methods The renal function of 64 ARAS patients was measured and compared with 36 healthy controls.Results Compared with the healthy controls, the incidence rates of morbilities of coronary artery disease, more than single-vessel, peripheral vascular disease, renal inadequacy increased significantly ( P<0.05), and the age, pulse pressure, levels of blood urea nitrogen (BUN), serum creatinine (SCr) were significantly higher ( P<0.01) in ARAS patients.Conclusion The elder, coronary artery disease, more than single-vessel, large pulse pressure, peripheral vascular disease and renal inadequacy are risk factors for ARAS. Severe renal artery stenosis may lead to renal inadequacy.

Objective:To investigate the fatigue damage mechanism of porcelain,and its relation with the microscopic defects in clinically failed all-ceramic crowns.Methods: Collecting the bilayered all-ceramic crowns failed in vivo.The fractured surfaces and occlusial surfaces of failed crowns were examined by an optical microscope followed by detailed fractography investigations using a field emission scanning electron microscope.When chemical impurities were of concern,energy-dispersive X-ray spectroscopy analysis was performed to examine chemical composition.A standard practice for fractography failure analysis of advanced ceramics is applied to disclose the fracture mode,and damage character.Results: Three types of fracture features are defined as breakdown of the entire crown,and porcelain chipping-off/delamination.Alumina crowns were usually characterized by breakdown of the entire crown,while zirconia crowns by porcelain chipping-off and delamination.The fatigue damage of porcelain was classified into surface wear,cone crack,and porcelain delamination.The observed microscopic defects in this study included air bubbles and impurity particles.Conclusion: The multi-point occlusial contacts were recommended in all-ceramic restorations clinically.The thickness of porcelain is important for the anti-fatigue ability of porcelain.Cautions have to be taken to avoid contaminations during the veneering processes.
