Objective To investigate the effectivity of bispectral index(BIS)and auditory -evoked potentials index(AEP index)in monitoring the depth of desflurane anesthesia in the elderly. Methods Sixty patients(ASA gradeⅠ～Ⅱ)without obvious auditory and psychiatric dysfunction undergoing general anesthesia were enrolled in this study,and they were devided into the elderly group (n=30)and the non-elderly group(n=30)according to the age.After the endotracheal intubation,the lungs were ventilated with desflurane in oxygen.End-tidal concentrations of desflurane were maintained at 0.6,1.0 minimum alveolar concentrations(MAC)and 1.3 MAC for 20 minutes, respectively.The changes of BIS,AEP index,mean arterial blood pressure(MAP)and heart rate (HR)were recorded simultaneously.Results In the elderly and non-elderly groups,BIS were 94.14?6.5 and 94.5?4.6(P＞0.05),and AEP index at pre-anesthesia were 87.2?11.7 and 89.2?6.9(P＞0.05)respectively,which showed no statistic difference between two groups.BIS and AEP index decreased significantly in each time point at pre-anesthesia compared with those during anesthesia in two groups (P＜0.05).In the periods of increasing concentration of desflurane,BIS decreased gradually in two groups(P＞0.05),but BIS in the elderly group were higher than in the non-elderly group at the same end-tidal desflurane concentration(P＞0.05),and BIS negatively correlated with the end-tidal desflurane concentration in two groups.In the elderly group,AEP index decreased significantly at the concentration of 1.0 MAC and 1.3 MAC of desflurane compared with that of 0.6 MAC(P＜0.05),but there was no difference in AEP index with increasing end-tidal desflurane concentration from 1.0 MAC to 1.3 MAC(P＞0.05).At every concentration of desflurane,AEPindexintheelderlygroupwaslessthaninthenon-elderlygroup(P＜0.05).Conclusions BIS and AEP indexes correlate well with the end-tidal desflurane concentration,and are valuable for monitoring the depth of desflurane anesthesia in the elderly.AEP index can predict the difference in depth of anesthesia at the same end-tidal desflurane concentration between the elderly and the non-elderly.

OBJECTIVE To study the audiological and etiological characteristics of infants failed to pass hearing screening. METHODS 126 infants received audiological diagnostic tests,including auditory brainstem response(ABR),40 Hz auditory event related potential(40 Hz AERP),distortion product otoacoustic emissions(DPOAE),tympanometry and acoustic reflex. The degrees and types of the hearing loss,and etiological characteristics were analyzed. RESULTS Among 126 infants (252 ears),61 were diagnosed with sensorineural hearing loss(48.41%),48 were conductive hearing loss(38.09%),and 17 were found to have normal ABR thresholds(13.49%). The hearing loss was associated with various factors,including history of infection during pregnancy(21 cases),threatened abortion(9 cases),pregnancy with age at or over 35(6 cases),extension of pregnancy(7 cases),history of systematic diseases(10 cases),history of neonatal jaundice(13 cases),history of asphyxia and hypoxia(18 cases),premature and low birth weight neonates(8 cases),neonatal diseases (8 cases),family history of deafness(5 cases),craniofacial deformity(3 cases),central nervous system disorder(6 cases),and 9 cases were second child. CONCLUSION The infants who failed to pass hearing screening have various etiology characteristics in hearing loss. The infants associated with risk factors were mostly found to have sensorineural hearing loss.

In order to identify novel genes involved in spermatogenesis, testis cDNA samples from Balb/C mice of different postnatal days were hybridized with the whole mouse genome Affymetrix chip to screen the testis-specific genes. The characteristics of the selected genes were analyzed by RT-PCR as well as other bioinformatic tools. A novel differentially expressed testis-specific gene (GenBank Accession No: NM_029042) in the developmental stages of testes was identified, and named TSCPA. Cellular mapping prediction of TSCPA indicated that its protein was probably expressed in nuclei, and one putative domain (aa 332-377) was anchoring domain of cAMP-dependent type II PK. The result of subcellular localization of GFP-TSCPA fusion protein in Cos-7 cells showed that TSCPA protein was expressed in nuclei. RT-PCR analysis revealed that TSCPA was expressed specifically in mouse and human testis. TSCPA gene was expressed weakly in 21-day-old mouse testis and the expression was increased gradually from 38th day to 6th month of mouse testes. No expression of hTSCPA was found in cryptorchidism and Sertoli-cell-only syndrome patients. It was concluded that the expression profile of TSCPA in human and mice indicated that TSCPA might play an important role in spermatogenesis.

Objective To detect the expression of caveolin-1 and PY14caveolin-1 in different esophageal tissues,and study the relationships between the expressions of caveolin-1 and PY14caveolin-1 with the occurrence and development of esophageal squamous cell carcinoma.Methods The fresh surgical specimens in 60 patients with esophageal squamous cell carcinoma were collected and Western blotting were used to analyze and detect the expressions of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma,adjacent esophageal tissues and normal esophageal tissues.The expression of cav-1 and PY14caveolin-1 with esophageal squamous cell carcinoma were analyzed.Results The expressions of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma were much higher than that in adjacent tissues and normal esophageal tissues,and the difference between them was statistically significant(P＜0.05).Conclusion The expression of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma, adjacent esophageal tissues and normal esophageal tissues decreases successively,it suggests the caveolin-1 and PY14caveolin-1 may be the key of the occurrence and development of esophageal cancer cells and they could be involved in the migration and invasion of esophageal cancer.

Objective To present a medical image transmission scheme based on fast healthcare interoperability resources(FHIR) proxy gateway which can enable medical personnel to access the hospital's medical imaging system via the Internet using mobile terminals,and then raise the medical staffs' working efficiency.Methods RESTful WebServices as the interoperability mechanism of image data was used in combination with FHIR image resource model and construct an intermediate gateway to three-tier network architecture,in order to solve the problem of transmitting image data to mobile terminals through gateway via the hospital's network.Results During its half-year trial run,the Internet mobile terminal reading system based on this method ran stably and was in good condition,in the actual hospital environment.Conclusion The gateway method is simple,flexible,and can fully support the mobile terminals' access to the background image data center.

Sarcophagous beetles play an important role in estimating postmortem interval time (PMI) in the later stages decomposition of carcasses. However, the morphological similarity of beetles usually poses a challenge for forensic scientists within their routine work. As a supplementary to traditional morphological method, molecular genetics identification is simple and time-saving. A molecular identification method involving a 288-bp segment of the 16S ribosomal RNA (16S rRNA) gene from 15 beetles of Silphidae (Coleoptera), collected from 5 locations in 4 Chinese provinces, was evaluated. Phenogram analysis of the sequenced segments by the unweighted pairgroup method analysis (UPGMA) method showed that all specimens were properly assigned into four species with strong similarity, which indicated the possibility of separation congeneric species with the short 16S rRNA fragment. These results will be instrumental for implementation of the Chinese database of forensically relevant beetles
