Objective To obtain the effective characteristic information for the standardization of diagnosis of traditional Chinese medical(TCM) syndrome in rheumatoid arthritis(RA).Methods Fifty-four items of symptoms and signs in RA patients were input into the computer,and Mahalanobis distance discriminant analysis(DDA) was used for the selection of effective indexes.Results According to the weight value and the result of T test,17 items from 54 had the highest rate of discrimination accuracy,up to 96.5%.Conclusion The results of computerized pattern recognition for the syndrome diagnosis of RA are consistent with the clinical diagnosis,which indicates that computerized pattern recognition can be used for the standardization of syndrome diagnosis of RA.

0bjective To evaluate the changes in blood oxygen saturation and pulse rate of the nurses under abrupt highland advancing and provide the fundamentals for those nurses under abrupt highland advancing to Tibet. Methods We selected 12 nursing staffs abruptly advanced to Lhasa at an altitude of 3 650 meters for Abrupt Advancing Group then chose 12 nursing staffs over there for Highland Group from November 2017 to December 2017. To assess whether there is a difference about the change of blood oxygen saturation and pulse rate between these two groups, we measured them in 24 nurses and 360 shifts before work and at 0.5, 1.0, 3.0, 6.0 h after work. Then, we compared the changes in blood oxygen saturation and pulse rate between different ages, sexes, shifts. Results No significant difference in blood oxygen saturation was observed between the two groups before starting work (P > 0.05). Blood oxygen saturation of Abrupt Advancing Group (0.5, 1.0, 3.0, 6.0 h) after work was respectively 0.91±0.01, 0.91±0.02, 0.91±0.02, 0.91±0.01. Meanwhile, the parameters of Highland Group was separately 0.94± 0.02, 0.93 ± 0.01, 0.94 ± 0.01, 0.94 ± 0.01. There was a significant difference between the two groups (t=5.153-8.151, P<0.05 or 0.01). Before work, the pulse rate was (85.38±2.38), (91.62±2.79),(89.79±2.05), (89.12±2.29), (89.72±2.31) times/min for Abruptly Advancing Group, (93.52±2.64), (93.52±2.82), (94.52± 2.73), (94.52±2.56), (93.52±2.96) times/min for Highland Group. The difference between the two groups was statistically significant (t=3.875-10.182, P<0.01). Besides, no difference about the changes in blood oxygen saturation of Abruptly Advancing Group between different shifts was observed (t=3.561-8.321, P<0.05 or 0.01). The difference of pulse rate in Abruptly Advancing Group was statistically significant (t=1.529-4.968, P<0.05 or 0.01). There was no significant difference of blood oxygen saturation and pulse rate in Abruptly Advancing Group between the age of 21 to 30 and 31 to 40 years old, whether before or after work (P > 0.05). A positive difference between the sexes could be found about the changes in the blood oxygen saturation of Abruptly Advancing Group at 0.5, 1.0, 3.0 and 6.0 h after work. What′s more, there was a significant difference in pulse rates before and after work (t=3.283-6.719, P<0.05 or 0.01). Conclusions The nursing staff in the Abruptly Advancing Group shows decreased blood oxygen saturation and increased pulse rate compared to those in the Highland Group during working period. In addition, the changes show more significant in those working at night, but they adapted gradually. Gender and working time have a significant effect on the change in blood oxygen saturation and increased pulse rate of the nursing staff.
