Objective:To discuss the relationship between the serum level of interleukin-6 (IL-6) and the presence of an intrauterine contraceptive device (IUCD). Methods:The experimentalgroup was subdivided into the bleeding and the non-bleeding groups which consisted of 64 womenwith IUCD. There were 60 healthy women in the control group. The serum levels of IL-6 and C-reactive protein (CRP) were detected by enzyme-linked immunosorbent assay (ELISA) in bothgroups. Results :In the experimental group,the serum levels of IL-6 in 3 cases were increased,andthere was a significant difference in comparison with those of the control group (P＜0. 01),butthere were no statistical differences between the bleeding group and the non-bleeding group withIUCD (P＞0． 05). Serum CRP was negative both in the experimental groups and in the controlgroup. Conclusion:The non-bacterial endometrial inflammation induced by IUCD causes the in-crease of serum level of IL-6 in some women. It is suggested that IL-6 may play an important rolein the contraceptive mechanism of IUCD.

Objective To explore the impact on survivors's health and to determine the risk factors involved in the typhoon in order to investigate the characteristics of traumatic symptoms of casualties in the aftermath of the Saomai Typhoon sweeping over the rural area of Zhejiang province in 2006. Method A cluster sampling study was carried out and a total of 389 survivors were assessed. Data were analyzed by univariate and multivariate Logistic analysis to clarify the characteristics and the risk factors of getting traumatize. Results Of 389, there were 113 (29.1% ) victims suffered from a variety of injuries mainly crush trauma (24.4 % ) and wounded by hard object (23.1% ). Moreover, the combined injuries accounted for 9.2%. The risk factors causing injuries in the residential area were the building collapse, glass fragments from broken windows, flying debris as well as fall from high place. Condclusions Outdoor activity and the crumbled building are the leading causes for injuries during the sweeping of typhoon. Meanwhile, we should make more effort to publicize the precautions against typhoon to the local residents.

Objective:To compare the steam distillation( SD) and supercritical CO2 ( SFE-CO2 ) method in the extraction of vola-tile constituents from such 3 traditional Chinese drugs as cnidium monnieri, radix sileris and atractylodes lancea in compound Kuhuang prescription. Methods:Essential oil was extracted from the 3 traditional Chinese drugs by SD and SFE-CO2 method, respectively. The components were identified by GC-MS, and their relative contents were calculated with peak area normalization method. Results:To-tally 36 components were isolated and identified using SD extraction and 31 components were identified using SFE-CO2 extraction, a-mong them, 22 components were the same and their relative molecular weight mainly concentrated within 200-230. Conclusion: SFE-CO2 method can extract effective components from the 3 traditional Chinese drugs in compound Kuhuang prescription with higher selec-tivity, which is the more suitable extraction method for essential oil from the prescription.

OBJECTIVE To investigate the radiological findings of labyrinthitis and evaluate the diagnosis value of HRCT and MRI. METHODS The HRCT and MR images of 27 cases ( 31 ears) with labyrinthitis,suggested by clinical examinations and abnormal changes on images coexisting,were studied. RESULTS In the 22 ears which underwent HRCT examinations,6 ears showed increase of the density of one or more structures of inner ear,8 ears showed increase of the density of structure as well as change of the shape of the inner ear,1 ear showed change of the shape only. Labyrinth inner cavity appeared local or total sclerosis and disappearance in 7 ears. Among the 22 ears,there was bony incompleteness in 4 besides the changes mentioned above. In the 9 ears which accepted HRCT and MR scanning,7 ears showed abnormal changes of different degree in the inner ear on HRCT images and the other 2 appeared normal. On MR images,all 9 ears showed decrease or disappearance of the signal of T2WI in one or more structures of membranous labyrinth. Among the 6 ears which performed contrast scanning,markedly enhancement was seen in 4 and no enhancement in 2 ears. Of all the 31 ears,cochlea was involved in 30,of which only basal turn involved in 5,upper and second turns in 2 and all turns in 23,semicircular canal involved in 26,vestibule in 20,oval window in 18 and round window in 19. CONCLUSION HRCT can demonstrate the abnormal changes of bony labyrinth,and MRI is helpful to detect the changes of labyrinth inner cavity. They have important value in the detection and diagnosis of labyrinthitis.
