Objective To evaluate the effect of lidocaine and tramadol on remifentanil combined general anesthesia. Methods Eighty patients undergoing abdominal hysterectomy were divided into group LT,L,T and C by random digits table,each with 20 cases .In group LT,during induction,the patients were intravenously. In group L,only used lidocaine as introduced in group LT. In group T,only used tramadol as shown in group LT. In group C,used the same volume of saline solution. The changes of mean arterial pressure (M A P) and heart rate during the operation, dysphoria grade (RS), Ramsay score (RSS), pain score (VAS),extubation time(ET),medication and dose,complications were recorded. Results In group LT,the dosage of propofol [(450 ± 178) mg] was less (P < 0.05), ET [(15.0 ± 4.8) min] was shorter (P < 0.05),during recovery time, RS was lower, RSS was higher,the cases needad fentanyl (1 case), 48 h after operation, only 1 case needed pethidine to relieve pain was less than those in other groups (P < 0.05). In group L there was a tend that its RS and the cases needed fentanyl and fentanyl dosage were more, RSS was less than those in group T during recovery time,but 48 h after operation,the cases needed pethidine was less than that in group T. Conclusions Using lidocaine during operation may relieve pain after operation, reduce the dosage of analgesic;giving tramadol may alleviate the acute pain and lower dysphoria incidence rate after remifentanil anesthesia. Combining them will get a better effect.

BACKGROUND:Three dimensional finite element analysis is widely used in orthopedics, but research in the knee flexion movement is not much. OBJECTIVE:To analyze biomechanical properties of knee flexion using finite element analysis.METHODS:Three dimensional finite element models and models of knee flexion at 30 degrees, 60 degrees and 120 degrees were established. Femoral forward movement, femur inward movement, tibia internal rotation and tibia vara were analyzed at different flexion angles. RESULTS AND CONCLUSION:(1) When knee flexion was at 30 degrees, 60 degrees and 120 degrees, the femur had backward movement. The backward movement value was larger at 60 degrees than at 30 and 120 degrees (P<0.05). The backward movement value was larger at 120 degrees than at 30 degrees (P>0.05). (2) The femur had outward movement at 30 degrees, and inward movement at 120 degrees. The inward movement value was significantly larger at 120 degrees than at 30 and 60 degrees (P<0.05). No significant difference in outward movement was determined between the 30 and 60 degrees (P>0.05). (3) Tibia internal rotation was not significantly different at 30, 60 and 120 degrees of flexion (P>0.05). (4) Tibia vara was found at 30, 60 and 120 degrees of flexion, but the tibia vara was not obvious at 120 degrees. The tibia vara was maximum at 60 degrees, and significantly higher than that at 120 degrees (P<0.05). The tibia vara was larger at 30 degrees than at 120 degrees (P>0.05). (5) These findings verify that backward movement was most obvious at 60 degrees. Femur inward movement was most large at 120 degrees. Tibia internal rotation was noticeable at 30 and 120 degrees. Tibia vara was remarkable at 60 degrees.

To investigate the health impacts of crystalline silica mixed dust and other potential occupational hazards on workers in ceramic factories, a cohort study of 4851 workers registered in the employment records in 3 ceramic factories in Jingdezhen city of China between 1972 and 1974 was identified. The cohort mortality was traced throughout 2003 with an accumulation of 128970.2 person-years, revealed 1542 deaths. Standardized mortality ratios (SMRs) were calculated for the main causes of death by using Chinese national mortality rates as reference. The mortality from all causes in three ceramic factories was 12.0 per thousand and the cumulative mortality was 31.8%. Malignant neoplasm, cardiovascular diseases, respiratory diseases, infectious diseases were the first four illnesses that threaten workers' life, and they accounted for 73.2% of all deaths. The results of this study showed that the standardized mortality ratio for all subjects was 1.02, which is very close to that expected on the basis of the China national mortality rates. Statistically significant mortality excesses for respiratory disease (SMR=1.36), pneumoconiosis (SMR=37.34), infectious disease (SMR=5.70) and pulmonary tuberculosis (SMR=3.88) were observed. The mortality of 2938 dust-exposed workers was higher than that of 1913 non dust-exposed workers. Except for pneumoconiosis, the mortality from lung cancer, non-malignant respiratory diseases and pulmonary tuberculosis in dust-exposed workers were significantly increased as compared with that in non-exposed workers, and the relative risks (RRs) were 1.86 (1.16-2.99), 2.50 (1.84-3.40), 1.81 (1.34-2.45). The exposure-response relationships between cumulative dust exposure level and mortality from all causes, colorectal cancer, lung cancer, respiratory diseases, and pulmonary tuberculosis were also identified. The findings indicated that silica mixed dust in ceramic factories has harmful impact on the workers' health and life span in ceramic factory.
