Objective:To control the maintenance cost of medical equipment and improve the efficiency and service level for maintenance, and to research the management about classification maintenance for medical equipment based on analytic hierarchy process (AHP).Methods: 69 clinical department and 14 engineers were involved in the questionnaire survey and the evaluated factors were obtained from their questionnaires. The (AHP) was used to determine what is the factor weight of maintenance for the medical equipment, and then calculate the maintenance scores of the equipment. Finally, the weight scores were applied to ABC classification method and the equipments will be divided into three types (A\B\C) as this method, and they will be managed by different mode.Results: Depended on the sixth order analysis data from 6 factors of evaluation (price, frequency, stability, running time, standby factor and difficulty of maintenance) that were compared between any two factors by using AHP, through comprehensive scores ratio to got A\B\C classification and work out relative implement countermeasure of maintenance. The new classification management mode has achieved planning and preventive maintenance for key equipment, regular maintenance for major equipment, and maintenance after event for general equipment. After the method was applied, the fault rate of second half of 2016 year was decrease 30% compared with same time of 2015 year. The total cost of maintenance of 2016 year decreased 10% compared with that of 2015 year. And the satisfaction of clinical department for department of equipment was enhanced.Conclusion: The AHP is applied to classified manage medical equipment and maintain them as weight of factor. This method has resolved many problems on maintenance of equipment, such as confused primary and secondary, and formalism and so on. According to the factor weight of maintenance to manage medical equipment at classification mode, hospital can catch key point of maintenance of equipment, and the maintenance cost can be efficiently controlled, and the work efficiency and clinical service level of equipment department can be improved and enhanced.

Objective: To investigate the safety and effectiveness of transvenous embolization of cavernous sinus dural arteriovenous fistula with Onxy or in combination with detachable coils. Methods: Twelve patients with cavernous sinus dural arteriovenous fistula treated by transvenous embolization from February 2007 to December 2010 were analyzed retrospectively. Ten patients were treated via the inferior petrosal sinus approach, 2 were treated via the vein-superior ophthalmic vein approach. Eight patients used Onyx alone, and 4 used Onxy in combination with detachable coils. Results: Circled digit oneAngiography showed complete occlusion in 10 patients immediately after treatment, small amount of residues remained in 2 patients. Six patients were cured with Onyx embolization alone, 2 were improved, 2 were cured with Onyx in combination with detachable coils embolization, and 2 were improved. The total effective rate was 100%, the total cure rate was 66.7%, and none of the patients worsened or died. Circled digit twoTwo patients had intraoperative bradycardia, 3 had postoperative orbital ache. Circled digit threeAll patients received clinical follow-up for 6 to 32 months and no recurrent and worsened were found. Conclusion: The clinical efficacy of transvenous embolization of cavernous sinus dural arteriovenous fistula with Onxy or in combination with detachable coils is effective and safe.

Trials in public hospital reforms bear special significance for rational deployment of health resources and exploring the separation of hospital management from routine operations. The paper identified such setbacks in the present trials as easy technology measures, numerous models of separations, difficulty in setting pharmaceutical service fees, and inadequate governance. Authors also recommended such measures as searching for appropriate reforms for public hospitals locally, greater financial resources for completing the compensation mechanism of public hospitals, streamlining their management system for separation of management from operations, and improving governance. All these efforts are designed to enhance the public benefit nature of public hospitals.

Study of traditional Chinese medicine (TCM) syndromes is a key to the research of TCM modernization, and the core is the classification and diagnostic criteria of syndromes. The purpose of this article is to review the usage of classification algorithms of data mining in TCM syndrome researches, and comprehensively analyze the main features of algorithms and their applications. The appropriate classification algorithm should be chosen according to different research purposes. Rough sets and cluster analysis are suitable for exploratory research without requiring a prior knowledge. Fuzzy sets theory, neural networks and decision tree are suitable for syndrome diagnostic criteria research when the classification goal is clear, because they require a prior knowledge. Among them, fuzzy sets theory could be used in combination with other classification algorithms. Thus, some new methods such as fuzzy clustering, fuzzy rough sets or fuzzy decision tree might be more suitable for TCM algorithm classification research. It is suggested that some novel classification algorithms need to be developed to fit the condition of TCM syndrome, based on the interdisciplinary theories and technologies.

Objective:To investigate the effects of pristimerin therapy on the functions of Th17 and Treg cells in patients with allergic asthma,and expore the function of immune factors in therapy on allergic asthma. Methods:Extracted mononuclear cells in pe-ripheral blood of patients with allergic asthma,and given pristimerin intervention in vitro. Then used fluorescence-activated cell sorting analysis to detect the contect of Th17 and Treg,enzyme-linked immunosorbent assay to detect cytokine production of IL-17 and TGF-β, and Real-time PCR to detect the contect of RORγT and Foxp3. Results: Compared with the control group, experimental group had reduced expression of CD4+IL-17+T cells ( Th17 cells) ,and increased expression of CD4+CD25+Foxp3+T cells ( Treg cells) ,which all had the statistical significance (P<0. 05);displayed decreased level of IL-17,and increased level of TGF-β,which all had the statistical significance (P<0. 05);had reduced expression of RORγT,and increased expression of Foxp3,which all had the statistical significance (P<0. 05). Conclusion: Pristimerin therapy can remit the unbalance of Th17/Treg in vitro,hinting this drug may regulate allergic asthma by influencing immunologic balance,which offers the theoretical support for pristimerin in clinical application.

Symptom score, uroflowmetry and post voiding residual urine were recorded and analyzed. Results After 4 weeks of treatment, the IPSS, uroflowmetry and residual volume were improved significantly, P 0.1. Conclusions Reduction of symptoms and improvements of uroflowmetry in BPH patients treated with ? blocker.might be initiated through different mechanisms.

ObjectiveThe possibility of the hyperplasi a of prostatic outer gland was studied with transrectal ultrasound (TRUS) guided biopsies. MethodsTwenty-seven prostatic outer glands in patients suspicious for prostatic cancer (PCA) were biopsied by TRUS guided, the total sites were 47. The same site was biopsied in sagittal and longitudinal section respectively. The hypoechoic lesion was biopsied 2 times if it was discovered in the outer gland. The histological results were diagnosed in double blind. Results Twenty prostatic inner glands looked symmetrical hyperplasia; 9 outer glands became thin because of the compression, there was no compressive sign in 18 patients; there was a hypoechoic lesion in outer gland of 3 patients. Benign prostatic hyperplasia was diagnosed in the specimens of 47 sites. ConclusionsThe hyperplasia of prostatic outer gland can occur like inner gland because it is glandular tissue.
