METHODS: We searched PubMed up to September 1, 2010 to identify eligible studies. A total of 10 casecontrol studies including 2288 cases and 4096 controls were included in the meta-analysis. Statistical analysis was performed with Review Manage version 4.2. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of the association.RESULTS: The results suggested that there is no significant association between XPD Lys751Gln polymorphism and esophageal cancer susceptibility in the overall population. However, in subgroup analysis by histology type, a significant association was found between XPD Lys751Gln polymorphism and esophageal adenocarcinoma (for CC vs AA: OR = 1.25, 95% CI = 1.01-1.55, P = 0.05 for heterogeneity). CONCLUSION: Our meta-analysis suggested that XPD Lys751Gln polymorphism may be associated with increased risk of esophageal adenocarcinoma.展开更多

METHODS: According to age, 403 patients operated on for CRC in our department were divided into group A (< 70 years old) and group B (≥ 70 years old) and analyzed statistically. RESULTS: Rectal localization prevailed in group A (31.6% vs 19.7%, P = 0.027), whereas the percentage of R0 resections was 77% in the two groups. Comorbidity rate was 46.2% and 69.1% for group A and B, respectively (P < 0.001), with a huge difference as regards cardiovascular diseases. Overall, postoperative morbidity was 16.9% and 20.8% in group A and B, respectively (P = 0.367), whereas mortality was limited to group B (4.5%, P = 0.001). In both groups, patients who suffered from postoperative complications had a higher overall comorbidity rate, with preexisting cardiovascular diseases prevailing in group B (P = 0.003). Overall 5-year survival rate was significantly betterfor group A (75.2% vs 55%, P = 0.006), whereas no signif icant difference was observed considering disease-specif ic survival (76.3% vs 76.9%, P = 0.674). CONCLUSION: In spite of an increase in postoperative mortality and a lower overall long-term survival for patients aged ≥ 70 years old, it should be considered that, even in the elderly group, a signif icant number of patients is alive 5 years after CRC resection.展开更多

Methods： Statistical analysis was applied between before and after the implementation of PDCA-cycle in the management of high-alert Medications. Results： After PDCA- cycle, the rate of management of high-alert Medications increased from 59.5% to 94.6% （P〈0.01）, Conclusion： Our study suggested that the PDCA-cycle play an important role in the management of high-alert Medications, and then can increase the level of safety on management and utilization of medicine.展开更多

The analysis indicates the emphasis reason that result in the accidents in coal mines are artificial cause explosion of mash gas and coal dust, water flood, fire hazard. The accidents mostly happened on stope which is more often than other places, following by the driving work face. This not only supplies the managers with basic reference about safe administration, but also suggests the countermeasures in reducing accidents： improve the disposition of person, perfect all kinds of rules and regulations, severely investigate, analyze and deal with the accidents.展开更多

As always said, that young Gulf inherently consumerist element of first degree because of abundant liquidity and reasonable level of income compared to others of non - Gulf societies. Therefore, this research aims to study and analyze the impact of consumer awareness among the students of the Faculty of Business Administration in consumer protection in terms of the current role and hoped to guide consumption and its relationship to some economic and social characteristics of the consumers. In particular it has been studying the impact of some of the qualifications for heads of Kuwaiti families, their total monthly income and their place of residency inhabited by the expressive factors of consumer awareness in college students as well as their impact on the degree of preference for quality of consumer goods in being a low-price, median-price or expensive-price. In addition, it has been studying the relationship of these social variables noted with the role of government and consumer protection associations through what they are doing to develop laws and policies directed to develop and educate consumers. To achieve these goals, a special questionnaire has been prepared especially for this purpose has been met from a random sample of students from the University of Kuwait. I have been using the appropriate statistical analysis to study these goals. Thus, some of the appropriate suggestions and recommendations are obtained to achieve the objectives of this research.展开更多

The system can manage medical ultrasonic image by collecting, saving and transferring, and realize that section offices of ultrasonic image in hospital network manage. The system use network technology in transferring image between ultrasonic equipments to share patient data in ultrasonic equipments. And doctors can input patient diagnostic report,saved by text file and case history, digitally managed. The system can be realized by Visual C++ which make windows applied. The system can be brought forward because PACS prevail with various hospitals,but PACS is expensive. In view of this status, we put forward to the analysis and management system of digital ultrasonic image,which is similar to PACS.展开更多
