Objective The purpose of this study was to investigate the expression of mitochondrial motility-related gene mirol and mitochondrial energy metabolism during an acute bout of prolonged exercise. Methods CS7 BL/6 mice underwent a moderate intensity treadmill running with the slope of 0° and at the speed of 13m/min, and they were randomly divided into 5 groups:resting group(R),exercise groups running for 30min(E30),60min(E60),90min (E90) and 120min(E120),respectively. Respiratory control index and ATP synthesis activity in isolated mitochondria were detected. Skeletal muscle H_2O_2 concentration,mirol mRNA expressions were also measured. Results (1)mirol mRNA contents were significantly increased in groups E30 to E120,as compared with the group R;and mirol mRNA expression increased 32.8%, 107.6%,63.8% and 44.8% respectively in groups E30 to E120. (2)H_2O_2 contents of skeletal muscle were clearly increased in group s E30 to E120. (3)ATP synthesis activity elevated at 30 min of exercise and returned to the baseline thereafter,whereas respiratory control index without remarkable change in groups E30 to E120. Conclusion Muscular mirol mRNA expression significantly increased during 120min of exercise as compared with the resting status and thus facilitated the mitochondrial respiratory and ATP synthesis for matching the energy demand during exercise.

Objective To investigate the difference of amplitude of low-frequency fluctuation (ALFF) and fraction of amplitude of low-frequency fluctuation(fALFF) between Alzheimer's disease (AD)patients and normal aging (NA) controls by voxel-based analysis.Methods Thirty-one AD patients and 44 NA controls were enrolled in the study.Blood oxygen level dependent functional (BOLD) EPI data were obtained during resting-state by using 32-channel head coil.Data were realigned,normalized and then smoothed with 8 mm FWHM kernel.Resting-state fMRI toolkit(version 1.6) was used to generate ALFF and fALFF images.Independent two sample t-test was performed with SPM5 to compare ALFF and fALFF of AD and NA controls.Pearson correlation analysis was performed to examine the relationship between MMSE score and ALFF,fALFF parameters.The significance level was set to be uncorrected O.001 on the voxel level and 0.05 on the cluster level.Results AD patients showed increased ALFF in left temporal lobe (0.492 ±0.119) and right cingulated cortex (0.434 ± 0.093) of AD patients,which were 0.443 ± 0.068 and 0.380 ±0.081 in NA controls (t =2.658,2.227,P ＜ 0.05).Decreased fALFF was found in bilateral posterior cingulate cortices (1.167 ± 0.203) and increased fALFF was found in bilateral temporal lobes (left 1.226 ±0.127,right 1.146 ±0.214) with left side dominance,which were 1.453 ±0.269,1.134 ±0.088,1.014 ± O.132 in NA controls (t =5.001,3.695,3.285,P ＜ 0.05).Bilateral temporal ALFF and fALFF correlated with MMSE positively (r =0.768—0.909,P ＜ 0.05) with left dominance.Conclusion AD patients showed increased resting-state functional MRI changes correlated with MMSE score in the temporal lobes with left dominance,which indicated left temporal lobe may be the best location for the observation of disease progression in AD patients.

Objective: To study the relationship between dilated cardiomyopathy and nuclear lamina protein (LMNA) gene mutation in Kazak ethnics at Xinjiang area.
Methods: A Kazak familial dilated cardiomyopathy (FDCM) with 31 members was studied. In addition, 160 patients with idiopathic dilated cardiomyopathy (IDCM) with 160 healthy controls were enrolled in our study, and they were divided into 4 groups: IDCM-Kazak, IDCM-Han and Control-Kazak, Control-Han.n=80 in each group. Peripheral blood DNA were extracted, 12 exons with nearby introns of LMNA gene were detected by PCR and the ampliifed products were sequenced and compared with the standard template of CHROMAS and BLAST software to identify mutation sites. LMNA mutation in both Kazak and Han IDCM patients were investigated.
Results: A novel LMNA mutation (insC, CGG→CCG) at exon 7 was identiifed in a FDCM proband, it caused an amino acid substitution as Arg to Pro, and a known LMNA polymorphism loci rs4641 (c.1362C>T His454His) was fund at exon 10. In addition, LMNA polymorphism loci rs4641 genotype distribution (χ2=5.16,P=0.036) and allele frequency (χ2=4.50,P=0.034) were statistically different between IDCM-Kazak group and Control-Kazak group; while such differences were no statistic meaning between IDCM-Han group and Control-Han group. Logistic regression analysis indicated that LMNA polymorphism loci rs4641 was related to IDCM occurrence in Kazak ethnics (P=0.025, OR=0.412, 95% CI 0.189-0.896).
Conclusion: LMNA polymorphism loci rs4641 was related to IDCM in Kazak ethnics at Xinjiang area, which might be susceptible loci for IDCM occurrence.

OBJECTIVE To explore the outcomes of CO2 laser assisted stapedotomy with artificial stapes prostheses in the treatment of advanced otosclerosis. METHODS Between January 2010 and January 2014, 15 patients (16 ears) diagnosed as advanced otosclerosis accepted CO2 laser assisted stapedotomy with artificial stapes implantation in our department. The averaged preoperative air conduction threshold of the speech frequency was 70.21 dB HL, the averaged bone conduction threshold was 38.49 dB HL, the averaged air-bone gap (ABG) was 31.72 dB HL. All cases were followed up for more than 6 months after operation. RESULTS All cases accepted auditory follow up after 6 months postoperatively. The speech frequency average air conduction threshold was 43.7 dB HL, the average bone conduction threshold was 28.95 dB HL, the average ABG was 14.75 dB HL. The ABG≤20 dB was achieved in 9 ears (56.3%) and ABG closure (≤10 dB) was achieved in 6 ears (37.5%). No cases appeared intractable vertigo, sensorineural hearing loss, secondary facial paralysis and other serious complications. CONCLUSION CO2 laser assisted technique reduced the probability of serious complications of stapedotomy, most patients with hearing level improved significantly. It's a safe, practical, relatively economical choice for advanced otosclerosis.
