OBJECTIVE: To study the relationship of distortion product in cochlea with cochlear activity and hearing. METHOD: Time variances of distortion product of basilar membrane vibration in vitro guineapig cochlea were observed by laser interferometry. RESULT: Within half hour after a cochlea was isolated from a guineapig, distortion product accompanied with two-tone inhibition in cochlea, can be observed. As time passed, distortion product and two-tone inhibition effect disappeared at the same time. After that, the membrane contiune vibrating in response to the sound stimulus, but the vibration amplitude decreased obviously and continued decreasing until it disappeared completely. CONCLUSION Distortion product in cochlea is a symbol of cochlear activity which makes the membrane respond in large amplitude vibration to sound stimulus and exhibit two-tone inhibition. The former makes the hearing highly sensitive to sound stimulus, the later makes the hearing perform information abstract well.

Objective To explore the association between rs3179060C/A polymorphism in the ex-on 1 of TNF-a gene and hyperandrogenism and polycystic ovary syndrome (PCOS). Methods One hundred thirty PCOS women and one hundred seventy five normal women as controls were enrolled in this study. The genotypes were screened by polymerase chain reaction-On/off switch and the product was isolated by e-lectrophoresis on a 2. 5% agarose gel containing ethidium bromide and visualized using an ultraviolet transil-luminator. The relationship of TNF-a alleles to serum testosterone level was analyzed in PCOS patients. Results Three genotypes were identified, corresponding to CC, CA, AA, and two alleles were screened, corresponding to C and A. The frequencies of the CC, CA, AA genotypes were 58. 4% ,23.1% ,18.5% vs. 72. 0% , 17.7% , 10. 3% in PCOS group and control group, showing statistically significant difference between two groups( P < 0.05 ). The allelic frequency was 70.0% for the C allele and 30.0% for the A in P-COS group, and 80. 9% for the C allele and 19. 1% for the A in control group, respectively, showing statistically significant between two groups ( P <0.05). The relationship was not observed between rs3179060C/ A polymorphism and serum testosterone level in PCOS patients in Han Chinese racial origin ( P >0.05). Conclusions The TNF-a gene rs3179060C/A polymorphism may be a risk factor for the pathogenesis of P-COS in Chinese women, but it was not effect on hyperandrogenism in PCOS women.

Objective To evaluate clinical application value of DWI and reservation of liver function in patients with chronic liver disease. Methods Thirty cases of healthy control group, and 60 case group with chronic liver disease,including both 30 chronic hepatitis B and 30 cirrhosis. liver function in case group was analysed by venous blood samples. Case groups were divided into three groups according to MELD score: ＜30 group in 27 cases, 30 to 36 group in 17 cases, ＞36 group in 16 cases. All cases underwent liver magnetic resonance DWI. Among the case group, 15 cases were followed-up twice of pre- and aftertreatment. DWI images were read, ADC values of liver parenchyma were measured and standardized with the cephalospinal fluid (CSF) at the same slice. Used SPSS 13.0 for windows to treat the data, group comparison of ADC values were treated by one-factor analysis of variance, interclass comparison each other by SNK method, comparison between pretherapy and post-treatment by paired-samples t test. Results Healthy liver parenchyma of the control group is homogeneous signal on DWI. ADC pseudo-color pictures showed green on the homogeneous areas. Slightly restricted area of chronic hepatitis B showed irregular scattered patchy in DWI images, 25 cases in right and left lobes, 5 cases only in right lobe of the liver. ADC pseudo-color pictures reaveled blue region in proliferation-constrained areas. Restricted areas of the liver parenchymal become more evident, also showed an irregular liver edge in 30 cases of cirrhosis. The standarized ADC average values were: the healthy group (0. 47 ±0. 02) × 10-3 mm2/s, chronic hepatitis B group (0. 37 ±0. 03) × 10-3 mm2/s, cirrhosis group (0. 36 ±0. 04) × 10-3 mm2/s( F =97.05,P ＜0. 05).The difference between healthy group and patients group was statistically significant (P ＜ 0. 05 ). No statistically significant difference between groups of chronic hepatitis B and liver cirrhosis ( P ＞ 0. 05 ).Average ADC values of MELD score among groups of ＜ 30, 30 to 36, ＞ 36 were ( 0. 38 ± 0. 02 ) ×10-3 mm2/s,(0.35 ±0.02) × 10-3 mm2/s, (0.32 ± 0.03) × 10-3 mm2/s respectively. There is a significant difference among the three groups (P ＜0. 05). After treatment, DWI of 15 patients with chronic liver disease showed reduction in restricted areas, and the average ADC value from pre-treatment (0. 33 ±0. 03) × 10-3 mm2/s increased to(0. 38 ±0. 03) × 10-3 mm2/s, MELD score from pre-treatment 36. 01 ±6. 00 reduced to 27. 83 ± 4. 86. Conclusion DWI of chronic liver disease showed patchy diffuse restricted areas; more severe of the liver cell damage was, more worse the liver function was and lower ADC values was. ADC values increased after effective treatment, liver function recoved and diffuse restricted areas of liver parenchyma reduced.
