RESUMO
OBJECTIVE: To investigate the subjective symptoms of eyes induced by laser radiation in workers and its related influencing factors. METHODS: A total of 82 workers exposed to laser radiation were taken as exposure group, and 71 workers without laser radiation exposure as control group by judgment sampling method. The questionnaire survey and subjective symptoms of eyes were surveyed in these two groups. The work-site surveys of laser radiation job posts and laser irradiation testing were conducted to evaluate the exposure level of laser radiation on each post. The basic eye use and eye discomfort symptoms were investigated. RESULTS: The median of the laser radiation in 12 workplaces was 2.18×10~(-5) W/cm~2, and it was below occupational exposure limit(2.22×10~(-3) W/cm~2). The total detection rate of subjective discomfort of eyes in the exposed group was significantly higher than that in the control group(35.4% vs 15.5%, P<0.05). The results of multivariate logistic regression analysis indicated that laser exposure and smoking were the risk factors of subjective symptoms of eyes(P<0.05). CONCLUSION: Laser radiation operation has the risk of causing the subjective symptoms of eyes in exposed workers.
RESUMO
Objective To observe the effect of acupoint application of Chinese medicine on preventing constipation after stroke. Methods By means of randomized, double-blind, controlled study design, 96 patients of yang-syndrome stroke were randomly divided into observation group and control group, 48 cases in each group. Both groups were given conventional treatment for stroke and routine nursing for preventing constipation, and additionally, the control group was given acupoint application of placebo while the observation group was given acupoint application of self-made umbilical paste of Radix et Rhizoma Rhei(Dahuang) and Natrii Sulfas (Mangxiao). The incidence of constipation, frequency of laxative usage and adverse reactions of the two groups were observed. Results (1) The incidence of constipation of the observation group was lower than the control group on treatment day 7 and 14 , the difference being statistical significant(P 0.05). The observation group had better effect on improving stool properties(P 0.05). The adverse reaction of both groups was mild, and had no effect on the accomplishment of the treatment. Conclusion Acupoint application of Chinese medicine is effective and safe on preventing constipation after stroke, showing good prospects for clinical application.
