Objective To revise the manipulation tactics scale (MTS) and examine its reliability and validity. Methods 583 college students were assessed with MTS. Results ①Through item analysis and explore factor analysis, the revised MTS contained 24 items and 6 subscales which could explain 64.559% of the total variances. ②The results of confirmatory factor analysis showed that the revised MTS had good construct validities. By means of personality traits and social relationship as criteria, the results suggested the criteria incidental validity were sound. ③The Cronbach' s coefficients of the scales were 0.714,0.866, and test-retest reliabilities were 0.701,0.837. Conclusion The revised MTS has good reliability and validity.

Objective To observe the effect of MAC of the isoflurane at the general combined with epidural anesthesia with lidocaine and dicaine.Methods 78 cases of the cholecystectomy patients randomly double-blindly divided Ⅳ groups. General combined with epidural anesthesia were performed at the Ⅰ、Ⅱ、 Ⅲ groups. And general anesthesia were performed at the contronal group. The MAC of the isoflurane are checked with up-and-down method with electronic stimulation at left on C5 leveral. Results The MAC of the three observed groups of the general combined with epidural anaesthesia were 0.67?0.097%、0.68?0.084%、0.61?0.103 % differently. There is no siginificant difference.But the MAC of the general contronl group is 1.15?0.088%.There are siginificant difference with the three observed groups,The MAC of the isoflurane can be reduced with general combined with epidural anesthesia. Coinclousions The MAC the isoflurane can be reduced with general combined with epidural anaesthsia significantly compared with singal general anesthesia. And there are no significant different in the three observed groups.It is the pulsing action with lidocaine combined with dicaine at epidural anesthesia. The mechanism of anaesthesia with lidocaine or dicaine supposed to be the same.

Objective:To explore the health status of occupational benzene exposure workers, and to provide a scientific basis for the development of reasonable health monitoring and effective protective measures.Methods:In March 2019, the occupational health surveillance data were collected including blood pressure, electrocardiogram, blood routine, urine routine, liver function, etc of 7810 benzene contact workers in 150 enterprises in Jiangxi Province in 2017, to analyze and assess their health status.Results:Among the 7810 benzene workers, there were 5451 males and 2359 females; the average age was (40.5±9.9) years; and the median benzene working age was 3.5 years. The detection rate of hypertension was 17.0% (734/4317) , the abnormal rate of urine routine was 15.7% (1227/7810) , the abnormal rate of liver function was 8.6% (356/4147) , and the abnormal rate of electrocardiogram was 12.3%(963/7810). The detection rates of low count number of leukocytes, platelets, neutrophils and occupational contraindications were 4.6%(360/7810) , 1.4%(108/7810) , 4.2%(330/7810) and 1.4%(110/7810) , respectively. The detection rates of low count number of leukocytes, platelets and neutrophils in female were all higher than those in male ( P<0.05). The detection rates of low count number of platelets, neutropenia and occupational contraindications increased with age and working age ( P<0.05 ). There were significant differences in the detection rates of low count number of leukocytes, platelets, neutrophils and occupational contraindications among benzene workers in different economic types ( P<0.05) , and the highest among foreign companies, followed by private enterprise. There were statistically significant differences in the detection rates of low count number of platelets, neutrophils and occupational contraindications in benzene workers of different enterprise sizes ( P<0.05) , and the highest was found in micro enterprises, followed by small enterprises. Conclusion:In 2017, the occupational health status of workers exposed to benzene in Jiangxi province is not optimistic. It is necessary to strengthen the occupational health supervision of small and micro-sized enterprises, foreign enterprises and private enterprises, take the initiative to improve health surveillance, and effectively protect the physical and mental health of workers.
