500 ng/ml. Spiral-CT pulmonary arteriography(CTPA) was the main diagnostic method. Nineteen patients received thrombolytic therapy, Twenty-nine patients received anticoagulative therapy, 2 patients didn't receive any therapy because of bleeding. Five(10%) patients were cured, 43 (86%) patients got better, 2(4%) patients were dead. Conclusions The clinical manifestations of pulmonary embolism in the elderly were varied. CTPA is the main diagnostic method and ventilation-perfusion lung scan or pulmonary angiography can be done when it is necessary. Thrombolytic treatment can improve the survival rate of patients with acute pulmonary embolism.

Objective To study the clinical significance of sernm CA153,CA125 and CEA test in breast cancer.Methods The levels of CA153,CA125,carcinoembryonic antigen(CEA)and ferritin were measured in 60 patients with breast cancer(breast cancer group),36 patients with benign breast diseases(benign breast diseases group)and 40 healthy people(control group)by chemiluminometry.The four indices were compared and analyzed for their complementary diagnostic value to breast cancer.Results The levels of CA153,CA125,CEA,SF[(52.8±21.3)u/ml,(44.2±20.1)ng/ml,(8.9±5.2)ng/ml,(350.5±113.8)ng/ml]in breast cancer group were significantly higher than that of benign breast disease group[(17.3±8.8)u/ml,(15.6±8.5)u/ml,(2.0±0.8)u/ml,(1220.7±46.91)ng/ml](t=2.671,t=2.684,t=2.898,t=2.844,P＜0.01);The levels of CA153,CA125,CEA and SF pretreatment in breast cancer group were significantly higher than that after treatment[(25.5±3.7)u/ml,(15.0±8.4)u/ml,(4.6±3.3)ng/ml,(98.5±58.6)ng/ml](t=2.210,t=2.165,t=2.224,t=2.234,P＜0.05);The positive rate of 53.3%in breast cancer group for CA153+CA125+CEA+SF were lower than that CA153(56.7%),CA125(58.3%),CEA(63.3%),SF(68.3%)(χ~2=2.52,χ~2=2.652,P＞0.05;χ~2=3.85,χ~2=3.90,χ~2=3.98,P＜0.05);joint determination of CA153+CEA+SF experimental efficient 89.0%higher than the other four groups of the joint determination,but had no signiflcanle(χ~2=2.78,χ~2=3.10,χ~2=2.99,χ~2=3.01,P＞0.05).Conclusion The positive rate may be increased by combining test of serum CA153,CA125,CEA and ferritin in breast cancer.Thus the combined test might be of high value for the early diagnosis,improving the therapeutic effect and prognosis of breast cancer.

As important adhesion molecule on cell surface,integrin is a kind of important receptor family. It′s im- portant role is to mediate intercellular adhesion and adhesion between cells and extracellular matrix,also regulate proliferation,differentiation,migration of cells and tissue remodeling,and plays an important role in maintaining cellular form and growth.The present article made a short review about research progress of integrin β1 effect in cardiovascular diseases in recent years.

Objective To provide references for enhancing the connection between the need of society and the training mode of in-service postgraduates who major in health service management by analyzing the existing and potential in-service postgraduates' potential trainingwishes andexpectations.Methods Questionnaire surveys,which involved basic information,motivations and aspirations on the advanced studies,understandings and suggestions on the cultivating mode,were conducted among in-service postgraduates(Grade 2010 through Grade 2012) who major in health service management in BUCM and staffs in the departments of corresponding postgraduates.Data including 128 validated questionnaires were analyzed using descriptive statistics in excel.Results The data indicated that further education was welcomed by 87 in-service postgraduates(85.3％ of the survey samples),who had astrong willing to further study.Specifically,the following tendencies were obtained:interdisciplinary training combining research and practice was approved by 71 in-service postgraduates (55.5％ of the samples); career-oriented talent training mode was accepted by 90 in-service postgraduates(70.2％ of the samples); 79 in-service postgraduates (61.7％ of the samples) believed courses should include both theory and practice educations; flexible educational system was welcomed by 77 in-service postgraduates(60.0％ of the samples) ; 61(47.7％) in-service postgraduates wished to attend class on week-ends while 45 (35.0％) wished to attend class in evenings; group instruction method was recommended by 73(57.0％) in-service postgraduates; 104(81.3％) believed double-tutors system should be applied to academic dissertation,and the academic dissertation could be all kinds of research papers such as investigation report,which was approved by 97 (75.6％) in-service postgraduates.Conclusions Through the above analysis,it can be validated that education on in-service postgraduates who major in health service management is worthy of further development.Finally,colleges and universities are suggested to optimize the training mode in four aspects including training objective,curriculum provi-sion,teaching methods and graduation thesis.

OBJECTIVE To investigate the antimicrobial-resistant profile of Staphylococcus aureus isolated from clinical specimens. METHODS The isolates of S.aureus were obtained from all kinds of clinical specimens by routine methods.The identification and susceptibility test of the isolates were determined by Automated Microbiology Analyzer.Disk-diffusion was used for detecting meticillin-resistant Staphylococcus aureus(MRSA). RESULTS The isolates were mainly isolated from sputa and urines.62.1% of isolates were referred as MRSA.All isolates of MRSA were resistant to ampicillin/sulbactam,penicillin G and cefazolin.No isolates of MSSA were resistant to above drugs.All isolates were susceptible to nitrofurantoin and vancomycin.The resistant rates of the isolates of MRSA to clindamycin,erythromycin,gentamicin,tetracycline,rifampin,sulfamethoxazole and levofloxacin were 70.7%,86.6%,87.8%,82.9%,42.7%,30.5% and 91.5%,respectively,those of MSSA were 31.3%,41.7%,20.8%,20.8%,10.4%,29.2% and 6.3%. CONCLUSIONS The antimicrobial resistance of MRSA is serious,but the antibiotics have high activity to the isolates of MSSA except penicillin G in vitro.Vancomycin has very high activity to the isolates of MRSA in vitro.

AIM:By optical coherence tomography to observe macular thickness change characteristics and foveal images of patients with retinitis pigmentosa (RP).METHODS: From September 2014 to September 2016, 74 patients (148 eyes) with retinitis pigmentosa diagnosed in our hospital were selected, and 50 healthy subjects (100 eyes) as normal controls;two groups received optical coherence tomography and fundus camera detection.The images of the macular were obtained to observe and measure the thickness of the macular fovea and at 4mm temporal side, the center of papillo macular bundle.RESULTS:The results showed that: the thickness of the macular fovea and at 4mm temporal side of RP patients were the same as normal controls without statistically significant(P>0.05);the thickness of the center of papillo macular bundle was less than that of normal control with statistically significant (P<0.05).There were five types characteristics in OCT imges in RP patients: macular edema in 19 patients 38 eyes;retinal pigment epithelium and choroidal capillary thinning in 18 patients 36 eyes;retinal pigment epithelium atrophy in 12 patients 24 eyes;normal in 12 patients 24 eyes;different thickness of pigment epithelium layer in 13 patients 26 eyes.CONCLUSION: Optical coherence tomography (OCT) can be used to detect the macular lesions in a timely manner, to help understanding the development of the disease, and provide the clinical basis for the early diagnosis and treatment of patients.
