OBJECTIVE Through researching the ABR threshold, the cochlear morphology and miR-96 expression in the cochlear of BALB/c mice at different month's age, to find out if the miR-96 can regulate the age related hearing loss of BALB/c mice.METHODS ABR testing, AO/PI staining and scanning electron microscope were used to observe the ABR threshold and cochlear morphology of the BALB/c mice at the ages of 3 months, 6 months, 12 months and 18 months. Real-time PCR was used to detect the expression of miR-96 in the cochlea of BALB/c mice at the ages of 3 months, 6 months, 12 months and 18 months.RESULTS The ABR thresholds of BALB/c mice were (18.5±8.3), (45.8±7.8), and (85.6±15.6) dB SPL separately at the age of 3, 6 and 12 months. At the age of 18 months, no response was observed in the ABR testing with 120 dB SPL acoustic stimulation. In the AO/PI staining, we found that the outer hair cells was apparently lost since the age of 6 months and the loss of hair cells aggravated as the month's age increased. At the age of 12 months, no outer hair cells was left, inner hair cells was lost apparently too. With the scanning electron microscope, we found the changes of deficiency, lodging, fusion, shortening and inversion in the hair cell cilia. And these changes were aggravated as the month's ages increased. At the age of 3 months, the relative expression of miR-96 (2-△CT) was 0.0225±0.0073. The relative expression of miR-96 (2-△CT) in the cochlea were 0.0162±0.0048, 0.0116±0.0048, and 0.0050±0.0014 at the age of 6 months, 12 months and 18 months separately, comparing with the relative expression of miR-96 at the age of 3 months, the differences were significant(P<0.05).CONCLUSION The hearing loss, hair cells loss, and cilia damage aggravated as the month's age increased, but the miR-96 expression in the cochlea decreased. Which suggest that miR-96 might play an important role in the age related hearing loss.

Objective To assess clinical significance of the right side lymph node dissection behind recurrent laryngeal nerve (RLN) in papillary thyroid carcinoma (PTC).Methods Clinical data of 111 cases of PTC adimitted in our hospital (Department of Vascular and Thyroid Surgery,the Union Hospital of Fujian Medical University) from Feb.2013 to Mar.2014 were retrospectively analyzed.Central lymph node metastasis was analyzed.Univariate and multivariate analysis were made to analyze relations between the right side lymph node (Ⅵ b2) metastasis behind RLN and gender,age,tumor size,capsule infiltration and so on.Results Among 111 cases of PTC,71 had central lymph node metastasis (63.96％).Total metastasis number of the right side lymph node behind recurrent laryngeal nerve (Ⅵ b2) was 2.720±2.037,and the transfer rate was 27.03％ (30/111) (P＜0.05),all lower than those of Ⅵ bl.The one-way ANOVA results showed that metastasis of the right side lymph node behind RLN (Ⅵ b2) was related with age,lateral neck dissection,and Ⅵ b1 lymph node metastasis (P＜0.05) while Ⅵ bl lymph node metastasis was the only independent risk factor for metastasis of the right side lymph node behind RLN(Ⅵ b2) in PTC.Conclusion For patients with right PTC,the metastasis rate of Ⅵ b2 is high,thus dissection of this area is favorable and can accurately reflect lymph node metastasis and further to guide tumor staging and postoperative treatment.

Objective To assess the clinical significance of reverse trendelenburg position in preventing postoperative nausea and vomiting(PONV)in thyroid surgery.Methods 110 patients with papillary thyroid carcinoma(PTC) admitted from Feb.2013 to Mar.2014 were prospectively divided into experimental group and the control group according to whether reserve trendelenburg position was adopted.Univariate and multivariate method were used to analyze relations between PONV and surgical position,gender,age,body mass index,hypertension,surgical time,ASA classification,anesthesia,and motion sickness.Results Of the 110 cases of PTC,the incidence of PONV was 16.28％ (7/43) in the experimental group while it was 37.31％ (25/67) in the control group.The difference had statistical significance(P ＜ 0.05).Statistical analysis showed that PONV was related to patients'gender,surgical position,surgical time,and motion sickness,while only surgical position and motion sickness was the independent risk factors.Conclusion Reverse trendelenburg position surgery can help to prevent PONV and promote recovery.

The autonomic nervous function, blood pressure, coordinate motor and blood alcohol Concentration (BAG) of twenty-one healthy Han volunteers were examined before and after alcohol intake. The purpose was to assess the acute effects of low and moderate doses of alcohol on their coordinate motor and autonomic nervous function. The results showed that after alcohol intake the subjects' heart rate increased and the total power value (TPV) decreased significantly. After the intake of alcohol at low dose, the parasympathetic nervous function of the subjects lying supoine was inhibited significantly. After the intake of alcohol at moderate dose, both the parasympathetic and the sympathetic nervous functions were inhibited. After the intake of alcohol at low dose, both the systolic pressure and the diastolic pressure of the subjects standing up-right were decreased and the diastolic pressure of those lying supine were also decreased. After the intake of alcohol at moderate dose, the systolic and diastolic pressures of the subjects, either lying supine or standing up-right, were decreased. Some subjects showed ataxia after the intake of alcohol at low dose ,and some showed aggravated ataxia after intake of alcohol at moderate dose of alcohol. There was no relationship of BAG with the degree of changes in autonomic nervous function, blood pressure and ataxia. The results indicated that ataxia was induced to come on and the autonomic nervous function was inhibited in some subjects who had taken low and moderate doses of alcohol ,and the cardiovascular regulation was affected too. These suggested that the increase of alcohol intake is adverse to human body's adaptation to the sharp change of circumstance.
