Objective To summarize the nursing experience of combination therapy of highly agglutinative staphylococcin (HASL) with cisplatin for patients with malignant pleural effusions. Methods After fully draining of pleural fluid in 62 cases with malignant pleural effusion through pleural puncture through central venous catheters and simply suction bottles, we injected HASL and cisplatin into the patients' pleural cavities. During the therapeutic process, firstly, we drained the pleural fluid fully before injection, secondly, we directed the patients to cooperate well and alter the positions properly, and thirdly, we closely observed the patients' condition and adverse reactions. Results 54 of 62 cases were effective after the therapies. The effective rate was 87.1%.Conclusions In order to achieve a satisfled curative effect and reduce the adverse reactions, we need the cooperation of the patients, fully draining of the pleural fluid before injection and proper alternation of the patients' positions during the treatment process.

Objective To study the effect of using handhold magnifier on reading speed in patients with low vision and normal-sighted people. Design Prospective,control study. Participants Low vision (13 patients)and normal-sighted readers (37 persons) who use handhold magnifiers or the first time. Method Nine-point text was read by normal vision subjects without magnifier and then with two magnifiers with different magnification (+10 D,+20 D) in different eye-to-magnifier distance (10 cm,35 cm). Nine-point text was also read by low vision people with magnifiers. The big printed text under the same magnification without magnifier was also read by low vision group. Reading speed was recorded. Main Outcome Measures Reading speed (words per minute). Result For normal vision subjects,reading speed without magnifier (194.6?45.2 words/min) is faster than that with a 10D magnifier in an eye-to-magnifier distance of 10cm (159.7?44.7 words/min) (P=0.001),and distance of 35cm (162.5?46.7words/min) (P=0.002),respectively. Reading speed without magnifier is also faster than that with a 20D magnifier in an eye-to-magnifier distance of 10cm (150.3?43.3 words/min) (P

Objective To analyze the clinical significance and features of patient s' with inconsistent antineutrophil cytoplasmic antibodies (ANCA) test results between indirect immune fluorescence (IIF) and enzyme-linked immunosorbent assay (ELISA).Methods ANCA were detected with IIF and ELISA method jointly among 12 386 in-patients and a retrospective analysis on the proportion of clinical features and significance was made in 589 cases with inconsistent results using Microsoft Excel 2007 statistical software.Results Among the 589 patients,68 (11.5％) were diagnosed as vasculitis,in which 51 cases as ANCA-associated vasculitis,and 521(88.4％) were diagnosed as non-vasculitis including 181 connective disease and 340 non-connective diseases in which hypertension and cardiopathy were common.The common inconsistent results of ANCA were p-ANCA/ELISA (-),IIF (-)/anti-MPO (+),IIF (-)/anti-PR3 (+),IIF (-)/anti-PR3 (+) anti-MPO (+) accounted for 24.4％ (144/589),29.5％ (174/589),15.9％ (94/589),18.5％ (108/589) respectively,these accounted for 88.3％(520/589) of total inconsistency.Conclusion The spectrum of diseases and clinical characteristics varies widely and often presents with multiorgan involvement in patients with inconsistent ANCA results.These reasons make it easy to be misdiagnosed.Attention should be paid to identify and different these inconsistency.
