Serum anti-uveal autoantigen with coiled coil domains and ankyrin repeats (UACA) antibody titer was measured using ELISA in 32 patients with thyroid-associated ophthalmopathy ( TAO ) and 20 patients with Graves' disease (GD) without ophthalmopathy.The level of anti-UACA antibody in TAO group was higher than that in GD group [ (225.91 ± 144.21 vs 187.42 ± 46.77 ) pg/ml,P＜0.05 ],and especially higher in patients with ocular myopathy [ (254.35 ± 168.29 ) pg/ml ].It seems that anti-UACA antibody is the sensitive clinical marker of ocular myopathy in TAO patients.

Objective To investigate the change of threshold of electrical sense through experiments in the presence of electrical noise according to stochastic resonance phenomenon that has been observed in somatosensory system.Method Psychophysical experiments were carried out using both single stimulus method based on random-gradient method and one-interval-forced-choice method.The glabrous skin of human fingers was choosed as the experimental objects,which was stimulated by square wave electrical signal mixed with electrical noise.Result The corresponding threshold of electrical sense can be reduced by the effect of external electrical noises.Conclusion Although electrical sense is not natural sense,stochastic resonance can occur in it, and effect of noise on enhancing this sense can be implemented by controlling external noises.

To investigate the role of ERC,6 gene in the growth rate and antifungal susceptibility,Aspergillus fumigatus strain with extra copies of ERG6 gene was constructed.Open reading frame (ORF) of putative ERG6 gene was searched in A.fumigatus genome.A PCR fragment, ERG6 ORF sandwiched by its flanking sequences (about 1 kb respectively),was amplified and was then subcloned into vector pRG-AMA1- NotI to produce a recombinant plasmid pERG6,which was further transformed into uracil auxotroph A.fumigatus strain AF293.1 to produce the transformant AF-pERG6.In the same time,empty plasmid pRG-AMA1-NotI was also transformed into A.fumigatus strain AF293.1 to produce the transformant AF-empty as a control.Radial growth of the transformants was tested on minimal medium (MM) and YAG medi- um.Antifungal susceptibilities of these resahing transformants,AF-pERG6 and AF-empty,to the common antifungal agents were performed by using both disk diffusion and broth microdillution methods.A.fumigatus genome contains a ERG6 gene,of which the ORF size is 1 256 bp.Comparing to Candida albicans and Sacchromyces cerivisiae sterol methyltransferase,A.fumigatus Erg6p had 57% and 50% identity, and had 70% and 63% similarity in amino acid sequences,respectively.Radial growth of transformant AF-pERG6 was slower than that of transformant AF-empty.The antifungal susceptibilties of transformant AF-pERG6 to the antifungal drugs itraconazole,voriconazole,terbin- aline,amphotericin B,caspofungin and grisefolvin were same to that of transformant AF-empty.In A.fumigatus,extra copies of ERG6 gene have no effect on antifungal susceptibilities to itraconazole,voriconazole,terbinafine,amphotericin B,caspofungin and grisefolvin.Radial growth of A.fumigatus harboring extra copies of ERG6 gene becomes slower compared to the control.

ObjectiveTo assesses the skeletal development of adolescent in Yantai area, and investigates the characteristics of the tendency of their skeletal development. MethodsTotally 1180 healthy adolescents ( 574 males and 606 females ) at 10 to 20 years of age living in Yantai area were randomly selected, and their left wrist were radiated at the posterior-anterior position. The bones at wrist were scored according to the Chinese Wrist Skeletal Development Standard CHN Method. The correlation among skeletal age, chronological age and the sex were analyzed. ResultsSkeletal age positively correlated with chronological age (male: r=0.943,females: r=0.942,totally: r=0.942). ConclusionThe skeletal development of adolescent in Yantai area has the characteristic of acceleration. So it is necessary to establish a new skeletal age standard for the skeletal development of adolescent.

OBJECTIVE: To investigate the serum IgE with various postmortem intervals (PMI) in guinea pigs due to sudden death from anaphylactic shock and to explore the effect of refrigeration of corpse on serum IgE level and its application value in forensic medicine. METHODS: The animal death models of anaphylactic shock were established. The corpses were preserved at room temperature (20 °C ) for 6 h and then refrigerated at 4 °C. The serum was sampled at 6, 12, 24, 36 and 48 hours after death. The IgE level of serum was detected with ELISA. The control group was also established. RESULTS: The serum IgE level had significant. difference between the experimental group and the control group (P < 0.05). There was no significant difference among the experimental groups at 6, 12, 24, 36 and 48 hours post- mortem (P > 0.05). CONCLUSION If the corpses were placed in 4 °C conditions 6 hours after anaphylactic death, the serum IgE still shows a good marker within 48 h for forensic investigation.
