For the purpose of studying the diagnostic significance of the traumatic perforation of the tympanic membrane by the otologic endoscopy and video tape recording, one hundred and fourteen patients 117 ears, with ear drum injury caused by the head and facial trauma were examined and analyzed by using the Hopkin modle mult angle otologic endoscopy and the video tape recorder. The results showed that the traumatic perforation of te tympanic membrane were found in all four quadrants of the membrane,61 91% of the perforation located in the anteriorinferior quadrant,of the tense part of the membrane. The shapes of the perforation were spindle,triangular,slit, irregular and lune. The nontraumatic perforation of the tympanic membrane often located in the center or the margin of the membrane and were round or oval in shape. The otologic endoscopy and video tape recording can display the morphologic features of the traumatic and nontraumatic perforations of the tympanic membrane objectively and provide reliable diagnostic and investitgative method for the forensic practice.

Objective To study the clinical findings and audiological characteristics of auditory neuropathy. Methods Clinical findings, pure tone threshold, acoustic impedance audiometry, speech audiometry, auditory brainstem response (ABR) and distortion product otoacoustic emission( DPOAE) were analyzed in 23 cases of auditory neuropathy. Results The patients were predominantly youngster, female more than male. Pure tone audiometry revealed mainly binaural symmetric upward - sloping audiogram with mild and moderate hearing loss at low frequencies. Speech discrimination score was obviously reduced, which was disproportionately to the pure tone threshold. Ipsilateral and contralateral stapedial reflex were absent. ABR was severely abnor- mal. DPOAIE was normal or nearly normal. Conclusion Clinical findings and systemic audiometry revealed the main characteristics of auditory neuropathy, which could be used not only for the understanding, but also for the diagnosis of this disease.

BACKGROUND:The existed artificial anal sphincter cannot sense whether there are intestinal contents in the bowel and the state of intestinal contents, and the previous studies on the intestinal content signal did not included the different parts of colon and the signals of different intestinal content status.
OBJECTIVE:To compare the differences of ultrasound signals of different intestinal content status in different parts of New Zealand rabbits detected with transmission-type ultrasonic signal detection system.
METHODS:Twenty healthy New Zealand rabbits were used;the rabbits were divided into groups according to distal part of proximal colon, distal colon and distal rectum. Five positions of solid stool particles were selected randomly as the detection point in each group. The voltage signals of stool were measured under solid, fluid, gaseous, and deflation status of the lumen.
RESULTS AND CONCLUSION:In rectum, there were no significant differences in voltage signals between solid and gaseous conditions, while there were significant differences between fluid and deflation conditions (P=0.000). Multiple comparison showed there were significant differences between four conditions in distal part of proximal colon and distal colon (P=0). There were significant differences in voltage singles between rectum, distal colon and proximal colon under solid and fluid conditions (P=0). Multiple comparison showed there were significant differences in any part of large bowel for solid and fluid status (P=0). There were no significant differences in voltage singles between rectum, distal colon and proximal colon under gaseous and deflation conditions. There was interactive effect of intestinal contents between three parts of large bowel under the four conditions (P=0.000). Transmission-type ultrasonic detection system can distinguish artificial intestinal contents sensory nerves of various intestinal contents. And the application of ultrasonic detection system to detect the intestinal contents under different conditions can provide a new effective method for the research on artificial intestinal content sensory nerves.

Objective To explore the value of glypican-3(GPC-3)mRNA and paternally expressed 10(PEG10)mRNA in peripheral blood in diagnosis of metastasis in hepatocellular carcinoma(HCC). Methods With SYBR Green I as fluorescence signal,real-time fluorescent quantitative reverse transcription-polymerase chain reaction was employed to detect the expression of GPC-3 mRNA and PEG10 mRNA in peripheral blood from patients with HCC with metastasis(n=8),HCC without metastasis(n=12)and hepatic cirrhosis(n=11),and receiver operator characteristics curve(ROC)and specific parameters were adopted to analyse their value in predictive and exclusive diagnosis. Results The expression of GPC-3 mRNA and PEG10 mRNA in HCC with metastasis was significantly higher than that in HCC without metastasis and in hepatic cirrhosis(P<0.05),while there was no significant difference in the expression of GPC-3 mRNA and PEG10 mRNA between HCC without metastasis and hepatic cirrhosis.In single test,the sensitivities in the differential diagnosis between HCC with metastasis and HCC without metastasis were 66.7%for GPC-3 mRNA and 72.2%for PEG10 mRNA,and the specificities were 91.7%and 91.7%.respectively.The areas under ROC were 0.748 for GPC-3 mRNA and 0.812 for PEG10 mRNA.With two markers in parallel test,the sensitivity,specificity,negative likelihood and diagnostic accuracy were 90.7%,84.O%,0.11 and 83.3%,respectively.In serial test,the sensitivity,specificity,positive likelihood and diagnostic accuracy were 60.5%,98.7%,45.5 and 73.3%,respectively. Conclusion Detection of GPC-3 mRNA and PEG10 mRNA in peripheral blood may help to predict blood metastasis and extrahepatic metastasis of HCC,and PEG10 mRNA works better than GPC-3 mRNA.The serial test of GPC-3 mRNA and PEG10 mRNA is helpful to the predictive diagnosis of peripheral blood metastasis of HCC.
