OBJECTIVE:
To analysis the short-term medicinal treating effects in senile sudden deafness.
METHOD:
According the age. The sudden deafness patients were divided into to groups, older age-group (age > or = 60, a total of 70 cases), control group (age < 60, a total of 70 cases), period of treatment was 7 days, the result of pure tone test were reviewed, compared the improvement before and after treatment.
RESULT:
After treatment, the average hearing threshold of the older age-patients was improved. There was statistical difference (P < 0.05); effective rate of the senile sudden deafness patients (disease time < or = 7 days) was 61.76%, (disease time > 7 days) was 38.89%. There was statistical difference (P < 0.05); the total effective rate of the senile sudden deafness patients was 49.9%; the senile sudden deafness patients which following moderate deafness (hearing threshold < 55 dB), effective rate was 52%, control group was 84.62%. There was statistical difference (P < 0.05), but there was no significant difference in the patients with severe hearing loss.
CONCLUSION
The Course of disease has important significance for the prognosis of the senile sudden deafness patients. As soon as possible to improve peripheral vascular microcirculation, the prognosis could be improve conspicuously the prognosis of the senile sudden deafness patients were worse than the young patients.

MicroRNA (miRNA),sharing the character of regulating the transcriptional level and expression level of mRNAs,is one kind of small non-coded RNAs.At present,innate immune has become one of the hot topics for researchers,and miRNAs as a sort of bioactive substance greatly take part in the whole regulation progress.In detailed,miRNAs can influence the immune state of immune cells during innate immune period and further regulate inflammatory conditions in whole body.By systematically summarizing miRNA function during innate immunity,this present review may provide a reference for peer researchers.

OBJECTIVE:
To compare the CT scan results in patients with deviation of nasal septum and normal adults and to explore its values in evaluating the state of nasal ventilation.
METHOD:
Twenty-six patients with deviation of nasal septum and 15 normal people were recruited in the study. The nasal airway from anterior nostril to posterior nostril was evaluated with PhlipsTomos scan AV Expander Elspiral scanner. The indexes of nasal ventilation was measured with the image-analysis software. The results of CT scan between patients with deviation of nasal septum and normal people was compared.
RESULT:
(1) There was obvious difference between patients with deviation of nasal septum and normal people in the NMCSA, IMCSA, DNCAT and DICAT. There was obvious difference between patients with deviation of nasal septum with obstruction in the opposite side and normal people in the ONMCSA and ODNCAT. There was obvious difference between patients with deviation of nasal septum without obstruction in the opposite side and normal people in the ODNCAT. (2) In the patients with deviation of nasal septum, between nasal minimal cross sectional area and inferior turbinate's maximum cross sectional area, there is obvious relation, r = -0.394, P < 0.05.
CONCLUSION
CT is one kind of objective inspection method in evaluating the state of nasal ventilation. With the measurement of the nasal morphology and functional index, we can understand the state of nasal ventilation more comprehensively. And with this, the treatment and diagnosis of disease with nasal obstruction will be more scientific.

Objective:To evaluate the diagnostic value of spectral CT calcium suppression (CaSupp) technique in acute and chronic thoracolumbar compression fractures.Methods:A total of 31 patients with thoracolumbar compression fractures were given spectral CT and MR scans from March to October 2020 in the Second Hospital of Shanxi Medical University. Acute and chronic vertebral fractures were diagnosed by doctor A and B based on CaSupp diagram, and the consistency between the two doctors was evaluated by Kappa test. CT values of fractured vertebra and adjacent normal vertebra were measured on conventional CT and CaSupp graphs respectively, and the CT value difference between fractured vertebra and adjacent vertebra was calculated. Independent sample t-test was used to compare the conventional CT value and CT value difference, CaSupp CT value and CT value difference between acute and chronic fractured vertebra. Using MRI as the gold standard, the ROC curves were drawn to evaluate the subjective diagnostic efficacy of physicians and the diagnostic efficacy of each quantitative parameter. DeLong test was used to compare the area under the curve (AUC) of each quantitative parameter in pairs. Results:The number of vertebral bodies in acute and chronic compression fractures diagnosed by MRI was 48 and 11 respectively. The Kappa value of subjective diagnosis of acute and chronic vertebral fractures by doctors A and B was 0.782, and the AUC, sensitivity, specificity were 0.882 and 0.857, 85.4% and 89.6%, 90.9% and 81.8%, respectively. The differences of conventional CT value, CaSupp CT value and CaSupp CT value difference between acute and chronic compression fractures were statistically significant (all P<0.05), and the AUC values of conventional CT value, CaSupp CT value, conventional CT value difference and CaSupp CT value difference were 0.824, 0.930, 0.706 and 0.934, respectively. Pair comparison showed that the AUC of the CaSupp CT value and CaSupp CT value difference was greater than that of conventional CT value difference, with statistically significant differences ( Z=2.014, P=0.044, Z=2.028, P=0.043), while there were no statistically significant differences between other AUC values (all P>0.05). Conclusion:The dual-layer detector spectral CT CaSupp technique has high value in differentiating acute and chronic thoracolumbar compression fractures, and the CaSupp CT value and CaSupp CT value difference are recommended for diagnosis.
