Objective:To compare the dissolution results of doxazosin mesylate extended release tablets determined by a fiber-optic method and the imported drug registration standard method. Methods:The drug release process was determined directly with a FODT-601 fiber-optic medicine dissolution/ release rate process monitoring system. Aqueous solution of hydrochloric acid and sodium chloride was used as the dissolution medium, the paddle rotation rate was 75 r·min-1 , the detection wavelength was set at 246 nm while the reference wavelength was 550 nm. The detection length was 5 mm. Results:The standard curve of doxazosin mesylate was linear within the concentration range of 0. 468 1-11. 700 0μg·ml-1 and r values were greater than 0. 999 0. The intra-and inter-day RSD (n=6) was 1. 6% and 2. 0%, respectively. The recovery of doxazosin mesylate was 99. 0% and RSD was 1. 4(n=9). The results determined by the fiber-optic method were generally higher than those determined by the standard method, and there were some differences in the measurement results. Conclusion:Fiber-optic method shows the whole dissolution process objectively. It is particularly prominent in the research on the dissolution of rapid, extended and controlled release preparations. However, it can not replace the standard method yet.

Fully mobilize the working enthusiasm of staff, make them pay attention to the normative operation, and change the values of medical equipment for medical staffs, by using the appropriate rewards and punishment system.Results: The medical equipment operation of operating personnel who participate the appropriate training and grade evaluation could conform to the assessment standards. Conclusion: The safety and effectiveness of medical equipment can be effectively improved by upgrade the operating levels of using staffs, it is effectively extending the medical equipment service life and saving the medical equipment cost while upgrading the overall quality of medical cared by the hospital. It makes further sustainable development of hospital.

Objective: To introduce the centralized management method for the conventional medical equipment and its utilization benefits and economic benefits to hospital and clinical department through scientific management pattern. Methods: Through several parts such as utilization ratio, usage cost, daily maintenance, measure control and data analysis, they could explain the advantage and convenience after proceeding centralized management. Results:Reasonable and scientific centralized management pattern could reduce or wipeout the idle and waste phenomenon for conventional medical equipment, reduce the department's expenditure of equipment depreciation, enhance the economic efficiency to hospital and clinical department. Through timely preventive maintenance and measure control, not only could save the precious time for the service staff to share personal experience, enhance the equipment repair time and repair rate effectively, but also could guarantee the equipment operation status and operation stability, protect the safety of patient medical device's usage. Conclusion:By making full use of various valuable data, it could be the reference point for these device's analysis and evaluation. As a result, concluded from economic, safety and scientific research part, it is necessary to promote centralized management for the conventional medical equipment.

This study is based on the application of the medical simulator and the multimedia technology to the medical English teaching for overseas students during their clinical practice in surgical department.It shows that this teaching model is effective by delivering a good studying surroundings and various language carriers.

The RhD antigen is expressed only in human red blood cells (RBC).Its immunogenicity and clinical application are only next to ABO blood group system, and is widely used both for blood typing and prevention of hemolytic disease of the newborn. The traditional anti-Rh(D) is derived by fractionation of plasma from individuals who have been sensitized by pregnancy or transfusion, or have been deliberately immunized to produce anti-Rh(D). Because of the limited source of plasma, researchers began the study of monoclonal and recombinant antibody. Monoclonal and recombinant anti-Rh(D) antibodies may provide alternatives to the current plasma derived polyclonal IgG anti-Rh(D), but up to now,none of them have yet proved effective in humans for prevention of RhD immunity and hemolytic disease of the newborn.

Recently, a benign variant of scleroderma, called the C.R.S. T, syndrome, has ben ibed by Winterbauer. Patients with this disorder have skin changes such as Cermal and subr,utaneous calcinosis, Raynauds phenomenon, sclerodactyly, and te1angiectasia. With the passible exception. of the gastroirgestinal syaterh, involvernent of other organs is uncommon, and affected. individuals have a Iong clinical cgurse. A case of C.R.S.T. syndrome in 25-year-old femala in reported with brief reviev of literatures. The patient showed miultiple pea sized nodular depoaits on dermal and subcuta.neous layers of both elbow and. knee joints, Rayaauds phenamenon, sclerrodactyly with acroselerosis and sclerodermatous change on both hands and forearm and telangiectasia on face and both palms On eeophagogram, slight disturhance of passage at the cardioesophageal junetion area was noted.

Subungual exostosis is a solitary fibrus nodule on the inner border of the terminal phalanx of the great toe. Rarely, the terminal phalanges of other toes, particularly the little toe, or even the fingers are involved. The first appearance is a small pinkish growth projecting slightly beyond the inner free edge of the nail, which pushes upward and backward. A case of Subungual exostosis affecting 20 year old man, who has been suffering from bean sized nolule on subungual area of terminal phalanx of left 5th toe. The skin iesion developed 1 year ago, and increased size insidiously and tendemess on pressure or tight shoes was noted. Diagnosis was confirmed by histopathologic and radiologic studies, and treated witb complete excision of tumor mass.

In this paper a new type of cerebral circulation is introduced, including the basic principal, parameter algorithms and equipment design. The analyzer is developed on the basis of previous cerebral circulation analyzer and combined with the latest development of hemodynamics. It has the advantages of previous analyzer and overcomes its shortcomings frequently encountered in clinical that unable to finish the analysis without detection of all the intracranial vessels. It provides new functional module and adds indices such as hydraulic power, carotidshear stress, comprehensive index etc. This analyzer can be used for cerebral circulation dynamic analysis and auxiliary diagnosis of cerebrovascular diseases.

Objective To study the relationship between urinary laminin(LN) and diabetic nephropathy.Methods Using the method for concentrating urinary laminin based on precipitation with PEG-4 000 and γ-globulin.The concentration of LN in the urine of 83 diabetics was measured by RIA.The concentration of micro-albumin and Ccr in the urine and the levels of plasma glucose and HbA1c were also measured.Results The choice of 150g/L of PEG-4 000 and 0.5 g/L of γ-globulin was the best method for concentrating urinary LN.The urinary LN in all groups was significantly higher than that in control group.Conclusion Urinary LN is an indicator in the diagnosis of the early diabetic nephropathy.

BACKGROUND: Most of evidence-based studies include both adult degenerative scoliosis and adult idiopathic scoliosis, which lead to indirectness in the results, and suppress the promotion of the evidence.OBJECTIVE: To systematically analyze the current clinical researches, and to review the curative efficacy of lateral lumbar interbody fusion for adult degenerative scoliosis.METHODS: A computer-based research of Medline, EMBASE, CENTRAL, WanFang and CNKI databases from December 2015 to December 2016, was performed with the key words of lateral lumbar interbody fusion, direct lumbar interbody fusion, extreme lateral interbody fusion, minimal invasive surgery, adult scoliosis. The articles were screened based on the inclusion criteria, and the clinical symptom improvement and radiological changes were analyzed.RESULTS AND CONCLUSION: Totally 13 articles were included. In the treatment of adult degenerative scoliosis, lateral lumbar interbody fusion shows less blood loss, short hospitalization time, significantly improved symptoms, satisfactory correction at the coronal plane, and low incidence of long-term complications. However, it has the poor correction at the sagittal plane and high incidence of short-term postoperative complications. Therefore, intraoperative neurologic monitoring is necessary and the combination with internal fixation has obtained good effectiveness.
