OBJECTIVE:
To investigate the mechanism of the pulmonary injury in rats caused by chronic intermittent hypoxia (CIH) and to investigate the intervention effect of Edaravone.
METHOD:
Ninety-six male Wistar rats were divided into four groups randomly: the control group (NC), chronic intermittent hypoxia group (CIH), chronic intermittent hypoxia normal saline matched group (NS), chronic intermittent hypoxia edaravone treatment group (NE). The four groups were also divided into 1, 2, 3, 4 W time subgroups, and each time subgroup had 6 rats. After the experiment, sections of pulmonary were stained with hematoxylin-eosin (HE) and the level of SOD, MDA, PO2 and Ang II mRNA in rat homogenate pulmonary were measured.
RESULT:
Pulmonary histology revealed that the CIH group showed high levels of interstitial edema, alveolar atelectasis, inflammatory cell infiltration of alveolar epithelial cell, pulmonary injury were serious in 1, 2, 3, 4 W. But the pulmonary histology of the UC group and the NS group was normal. Compared with the NS group, pulmonary injury of NE group 1, 2, 3, 4 W, significantly decreased. Compared with the NC group, the levels of PO2 in the CIH group were decreased; while the compared with the NS group, the levels of PO2 in the NE group were increased. Compared with the UC group and NS group, the levels of Ang II mRNA in each time point in CIH group were increased gradually (P < 0.05), the content of MDA were increased in 1, 2, 3, 4 W (P < 0.05), they had reached the peak all at 4 W; while the SOD in each time point in CIH group were decreased gradually (P < 0.05) compared with that in UC group and NS group; The Ang II mRNA levels of CIH in pulmonary showed positive correlation with MDA [r = 0.782,P < 0.01]; while the Ang II mRNA levels of CIH in pulmonary showed negative correlation with SOD [r = - 0.904, P < 0.01].
CONCLUSION
CIH can cause pulmonary injury through oxidative stress and activating Ang II, and Edaravone could prevent pulmonary injury induced by CIH through scavenging oxygen free radicals.

OBJECTIVE:
To investigate the characteristics of tinnitus in patients with auditory neuropathy spec- trum disorder (ANSD).
METHOD:
This study recruited 14 ANSD patients with tinnitus. All the ANSD patients un- derwent detailed history taking, audiological examinations and assessments of tinnitus. This study analyzed the correlation of tinnitus status and hearing loss, and discussed the effects of sex, age, and the course of disease on tinnitus in ANSD patients.
RESULT:
(1) In the ANSD patients, tinnitus often occurred in 3 years after the onset of hearing loss; (2) Tinnitus was highly prevalent in ANSD patients, and the severity of tinnitus was mostly from mild to moderate; (3) There was no obvious correlation between the subjective grading of tinnitus and hearing loss de- gree, and the impact of curve patterns of hearing loss on the level of tinnitus need much more evidence-based proof; (4) Along with the course extension, the impact of tinnitus on the quality of life was much more obvious; (5) Some risk factors such as noise exposure could be the reasons of aggravating the degree of tinnitus.

To analyze the prevalence of motor cognitive risk syndrome (MCRS) and the decline of motor and cognitive function in elderly patients with small vessel disease (CSVD). Methods From June 2018 to August 2020,a total of 130 CSVD patients aged 60~80 years admitted in the seventh medical center of PLA General Hospital were included (46 of them were diagnosed with MCRs syndrome). A series of cognitive function and motor tests were examined,including mini mental state examination (MMSE),verbal fluency test (VFT),clock drawing test (CDT),trailmaking test Part B (TMT B),single task walking (STW),dual task walking (DTW) and dualtask cost (DTC). Univariate analysis was performed for general and clinical data. Variables with P< 0.05 were further included in the multivariate Logistic regression analysis to assess the risk factors of MCRS. Univariate analysis also was performed for the cognitive and motor function of patients with different levels of SVD. Results The incidence rate of MCRs is about 35.38% (46/130)in the study. The cognitive function of MCRS negative group was significantly better than that of MCRS positive group,VFT[( 17.695±4.069) vs. (16.083±3.319)],and MMSE[28(28.29) vs. 27(26,27)]. Compared with MCRS negative group,the motor function differences in DTW speed[(90.500±21.138) vs. (65.417±17.301)]mm/s and DTC[ 12.425( 5.845,18.985) vs. 16.190(9.605,22.925)]%. The multivariate Logistic regression analysis indicated that VFT(OR= 1.876,95%CI 1.329~2.648,P< 0.01),DTC(OR=0.900,95%CI 0.823~0.985,P=0.022),DWT speed(OR= 0.869,95%CI 0.809~0.933 P< 0.01),and MMSE(OR=0.055,95%CI 0.017~0.175,P< 0.01) was an independent risk factor of MCRs. After adjusting for age,gender,education level and coexisting diseases,VFT(OR=1.961,95%CI 1.276~3.014,P=0.002),DTW speed(OR=0.861,95%CI 0.767~0.966,P< 0.01),MMSE(OR=0.032,95%CI 0.007~ 0.146,P< 0.01)and DTC(OR=0.861,95%CI 0.767~0.966,P< 0.01)were still significant. Conclusion The cognitive and motor performance in MCRS positive group is significantly worse than that in MCRS negative group in CSVD patients. VFT,MMSE and DTW are influencing factors of MCRS. DTW is more likely to cause gait disorder,which is mainly manifested by the decrease of walking speed.

Objective:To investigate the protective mechanism of TRPV4 channel inhibitor on blood-brain barrier(BBB)damage after traumatic brain injury(TBI).Methods:The TBI rat model was established.TRPV4 channel inhibitor HC067047 or PKC-δ inhibitor Rottlerin was used to detect changes in BBB permeability,neurological function score,and the expression of microvascular endothelial tight junction proteins ZO-1 and ZO-2 in brain injury areas after TBI.Results:Compared with the Sham group,BBB permeability significantly increased,brain neurological function score significantly decreased,and the expression of ZO-1 and ZO-2 significantly decreased in TBI group(P<0.05).Compared with the TBI group,after administration of HC067047 or Rottlerin,changes in BBB permeability,brain neurological function score,the expression of ZO-1 and ZO-2 were partially reversed(P<0.05).Conclusions:TBI-induced BBB injury may be mediated by TRPV4 channel regulating PKC-δ signaling pathway to affect the expression of tight junction proteins ZO-1 and ZO-2.Inhibition of TRPV4 channel function or PKC-δ signal molecule can partially alleviate BBB damage induced by TBI.This study may provide new ideas for the treatment of clinical TBI.
