The effect comparison of different cleaning methods for laparoscopic in-struments / 中国现代医生

Objective To investigate the effect of laparoscopic hand and whole system cleaning method, and compare with endoscopic cleaning method for one hand before. Methods A total of 100 laparoscopic operation patients in our hospital from January 2012 to December 2013 as the research object, from January to December 2012, hand clean-ing method for cavity mirror one before the establishment group A(n=50), from January to December 2013 for hand supply one, establishment of group B (endoscopic cleaning method,n=50),group A endoscope cleaning hand forone before the group, group B for hand cleaning method for combined cavity mirror, the visual method of the two groups the rate of qualified,qualified rate of a magnifying glass,the qualified rate of occult blood test, the number of colony qualified rate, and the interval time of operation, qualified equipment package were compared between two groups. Results The visual method of group B qualification rate, magnifying glass, the rate of qualified, qualified rate of oc-cult blood test colonies qualified rate was higher than that in group A, with statistically significant difference between two groups(P<0.05). Operation time interval of the group B was significantly shorter in the group A, with statistically significant difference between two groups(P<0.05). qualified equipment package operation of group B was significantly more than group A, with significant difference between two groups (P<0.05). Conclusion The application of cleaning cleaning hands for development of management mode in laparoscopic instruments, is conducive to improving steriliza-tion quality,shorten the operationtime interval,thus greatly improve the efficiency and quality of nursing work.

Etiological analysis on bacterial ocular disease in northern China (1989-1998) / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To review the distribution and trends of bacterial culture specimens in Beijing Institute of Ophthalmology.</p><p><b>METHODS</b>A retrospective analysis of the bacterial culture-positive rate, the distribution of gram' s stain, and the distribution and change of isolates was performed on 4705 specimens during a 10-year period (1989- 1998).</p><p><b>RESULTS</b>Positive cultures numbered 1339 of the 4705 specimens, with a positive rate of 28.6%. Gram-positive cocci constituted 55.6% of the total isolates, followed by gram-positive bacilli 13.1% . Gram-negative cocci accounted for 2.8%, and gram-negative bacilli 28.5% . In the positive bacteria cultures, coagulase-negative Staphylococcus (mainly Staphylococcous epidermidis) was the most common isolate (25.3%), and followed by Pseudomonas 18.8%, Micrococcus 11.7%, Cotynbaccterium 10.1%, and Staphylococcus aureus 8.2% . During the 10-year period, the overall frequency of gram-positive cocci appeared to increase with time while the frequency of gram-negative bacilli decreased.</p><p><b>CONCLUSIONS</b>Gram-positive cocci and gram-negative bacilli are still the predominant pathogens of ocular infection in northern China. The frequency of the former increases annually whereas that of the latter decreases. It is important to comprehend the distribution and trends of ocular pathogenic bacteria for the diagnosis, prevention and treatment of bacterial infectious ocular disease.</p>
