Objective: To evaluate clinical, Quality of Life (QoL) and medical cost outcomes in patients with symptomatic reflux esophagitis (RE) receiving different ″triple combination therapy″. Methods: A multicenter medical effectiveness trial conducted in 10 hospitals of 5 regions in Zhejiang Province. 248 patient-volunteers were assigned to 8 weeks of ″ triple combination therapy″ with Lansoprazole plus Cisapride and Sucralfate or Ranitidine plus Cisapride and Sucralfate. Main outcomes assessment included symptoms scale scores, RE severity, QoL at baseline and 8 weeks. Medical cost data were collected with cost analysis questionnaire. Results: (1)More Lansoprazole group patients noted RE symptoms resolution than Ranitidine group(92.3% vs 78.4%, P<0.01). There was no striking difference between two groups in RE healing rate (90.8% vs 82.9%, P>0.05). (2)RE significantly impaired QoL of patients(P<0.001).Compared with Ranitidine group, QoL in Lansoprazole group had significant improvement (rate of ″good″ QoL 64.5% vs 45.6%, P<0.01). (3)There was close correlation between symptomic effectiveness and QoL rating scale in both the Lansoprazole and Ranitidine group(P<0.01, r=0.235 and 0.353 respectively). There were no statistical difference of medical cost between the two groups (P>0.05). Conclusion: RE significantly impaired QoL of patients. ″Triple combination therapies″ can significantly improve RE symptoms and QoL. Lansoprazole combination therapy was more cost-effective than Ranitidine combination group.  相似文献

The study of gross Anatomy through the use of cadaveric dissections in medical schools is an essential part of the comprehensive learning of human Anatomy, and unsurprisingly, 90% of the surveyed medical schools in Africa used cadaveric dissections. Donated cadavers now make up 80% of the total cadavers in North American medical schools and all the cadavers used for dissection in the United Kingdom are donated. Because the sources of cadavers used in Africa are not clearly known, a questionnaire to gather information on cadavers used at medical schools was designed from the relevant literature and was sent by electronic mail to 123 Anatomy lecturers in 23 African countries (48 medical schools). Fourteen lecturers from 14 medical schools in ten countries responded to the questionnaires. The results indicate that, in most countries, the cadavers are unclaimed bodies from the hospitals and prisons, and the bodies of dead bandits. In South Africa and Zimbabwe, the donations are mostly from the white community, and medical school in the Islamic country of Libya is importing cadavers from India. The lack of knowledge about body donation programes and firmly held cultural and religious burial traditions may explain the lack of bequests from black communities. The use of unclaimed bodies may disproportionally affect people who were homeless and poor, criminals, people with fewer social links, and social outcasts. The Anatomy lecturers felt that there should be broader national awareness programes for body donations, although the benefits of this could take decades to materialize.

宋代解额分配制度历经数代的改革,使解额本身的价值与唐代相比发生质变,使科举的政治功能明显强化,特别是解额分配在地区间坚持相对均衡的原则及在士庶阶层采取分流的原则,既体现了公正、公平的理性原则,也是权力资源分配面向诸社会阶层,减少各阶层之间在追逐权力时的矛盾,是巩固政权、安定社会的重大举措。因此,宋代的解额分配制度对后世的选才制度多有启迪。  相似文献

Research on information spillover effects between financial markets remains active in the economic community. A Granger-type model has recently been used to investigate the spillover between London Metal Exchange(LME) and Shanghai Futures Exchange(SHFE) ,however,possible correlation between the future price and return on different time scales have been ignored. In this paper,wavelet multiresolution decomposition is used to investigate the spillover effects of copper future returns between the two markets. The daily return time series are decomposed on 2n(n=1,…,6) frequency bands through wavelet mul-tiresolution analysis. The correlation between the two markets is studied with decomposed data. It is shown that high frequency detail components represent much more energy than low-frequency smooth components. The relation between copper future daily returns in LME and that in SHFE are different on different time scales. The fluctuations of the copper future daily returns in LME have large effect on that in SHFE in 32-day scale,but small effect in high frequency scales. It also has evidence that strong effects exist between LME and SHFE for monthly responses of the copper futures but not for daily responses.  相似文献

Background: The specialty of allergy developed quickly in western countries because of the rapid increase of allergic diseases, whereas it developed relatively slowly in China. The prevalence of allergen sensitization and allergic diseases in Zhejiang Province of China is high and improving the medical services for these diseases is critically needed. Objective: To investigate the working status of the diagnosis and treatment of allergic diseases, including doctor resources, diagnostic methods, and allergen-specific immunotherapy in patients of Zhejiang Province, and to provide instructions for the strategic development of subspecialties of allergic diseases. Methods: First we defined the doctors who treat allergic diseases, and designed a comprehensive questionnaire to collect personal and hospital information for these doctors. The questionnaires were distributed to hospitals with different ranks and from different areas in the province. The general condition of doctor’s resources, carryout of diagnostic methods, and allergen-specific immunotherapy were described and variations in the different specialties, hospitals, and areas were further analyzed. Results: Doctors in their thirties with bachelor’s degrees were the mainstream for diagnosing and treating allergic diseases. The main specialties of the doctor resources were the specialties of Ear, Nose and Throat (ENT), Respirology, Pediatrics, and Dermatology. The Pediatrics specialty had a more reasonable infrastructure of doctor resources with more young doctors working in this subspecialty. The development of allergy subspecialty varied within hospitals at different levels or from different areas. The carryout of the skin prick test (SPT), serum specific IgE (ssIgE), and subcutaneous immunotherapy (SCIT) was best performed in provincial hospitals, while sublingual immunotherapy (SLIT) was prescribed most commonly in municipal hospitals. The performance of SPT and ssIgE in Hangzhou, Jiaxing, and Wenzhou areas was much better than that in other places. The performance of SCIT and SLIT was best in Wenzhou. Conclusions: Our survey revealed a very initial and unbalanced development for the allergy subspecialty in Zhejiang Province. Doctor resources for allergic diseases were mainly from the specialties of ENT, Respirology, and Pediatrics, and the performance of diagnosis and treatment was mainly focused on provincial and municipal hospitals. Continuous education of allergies could be extended to primary healthcare centers and more efforts should be directed to those areas with poor medical resources.  相似文献

For many years, medical students at the University of Sydney undertook their clinical clerkships in traditional metropolitan teaching hospitals, which were regarded as the ‘gold standard’ for clinical training. In 2001 the university established a rural clinical school at which increasing numbers of students now complete a significant proportion of their medical education. The aim of the study reported here is to examine students’ perceptions of what facilitates their learning in clinical settings and to compare their perceptions across rural and metropolitan settings. Focus groups were conducted to collect students’ views on their experiences of learning in clinical settings. The findings were used to generate a questionnaire with items designed directly from focus‐group data ensuring content validity. The questionnaire was sent to all students in the 2004 cohort. Exploratory factor analysis was used to provide evidence of construct validity. The internal consistency reliability of the questionnaire was assessed using Cronbach’s alpha. Factor scores were computed to compare students’ perceptions across the two settings. Four factors were extracted: (1) clinical teachers’ orientation to teaching; (2) opportunities to develop clinical skills; (3) supportiveness of the clinical setting; and (4) student confidence and sense of self‐efficacy. Students rated the rural experience more highly and positively than the metropolitan hospital experience with regard to all four factors. This study highlights the positive role that rural attachments can play in providing an educationally sound learning experience. The findings are important in the context of both the drive, among medical programs worldwide, to seek out additional and alternative settings for clinical education and the national agenda to foster student interest in rural careers through positive rural training experiences.  相似文献

The Ethernet passive optical network (EPON) is the next generation of broad-band network technique. A crucial issue in EPONs is the sharing of uplink bandwidth among optical network units (ONUs). This article provides a novel dynamic bandwidth allocation algorithm, i.e. threshold dynamic bandwidth allocation (TDBA), which is based on adaptive threshold, to increase resource utilization. The algorithm uses ONU data-transmitting rate to adjust optical line terminal (OLT) receiving data threshold from an ONU. Simulation results show that this algorithm can decrease average packet delay and increase network throughput in a 10G EPON system.  相似文献

Learners of all ages face complex decisions about how to study effectively. Here we investigated three such decisions made in concert—time allocation, ordering, and spacing. First, college students were presented with, and made judgments of learning about, 16 word-synonym pairs. Then, when presented with all 16 pairs, they created their own study schedule by choosing when and how long to study each item. The results indicated that (a) the most study time was allocated to difficult items, (b) relatively easy items tended to be studied first, and (c) participants spaced their study at a rate significantly greater than chance. The spacing data, which are of particular interest, differ from previous findings that have suggested that people, including adults, believe massing is more effective than spacing.  相似文献
