Relationship between Autophagy and Repair of Spinal Cord Injury Based on Pathogenesis of Stasis Obstructing Meridian (review) / 中国康复理论与实践

Spinal cord injury is a kind of central nervous system injury disease caused by trauma. It was found that the up-regulation of autophagy after spinal cord injury could promote the repair of spinal cord injury. Under the condition of stress, autophagy can reduce the number of misfolded proteins and damaged organelles in cells to maintain the stability of intracellular environment. Chinese medicine with Huoxue Quyu Tongluo (against stasis obstructing meridian) efficacy has attracted much attention in the treatment of spinal cord injury, which may associate with the role of regulation of autophagy.

The Prevalence of BPPV in Patients with Meniere’s Disease / 听力学及言语疾病杂志

Objective To investigate the prevalence of BPPV in patients with Meniere’s Disease(MD),and to investigate the diagnostic and predictive values of VEMP in patients with MD and BPPV.Methods A total of 1 1 6 patients previously diagnosed MD were followed up through telephone about their BPPV-like attacks.We recorded the detailed history of BPPV-like attacks,and provided them with complete Dix-Hallpike and roll tests if patients were on their BPPV-like attacks.Results In all,4 patients'histories supported BPPV,and 4 patients were found with BPPV.The prevalence of BPPV in patients with MD was 3 .4%(4/1 1 6 ).Meniere's symptoms preceded the on-set of BPPV in 8 patients.In 4 confirmed BPPV patients with Meniere's disease,BPPV was limited to the same ear as the MD in 2 cases,and 1 had contralateral BPPV,and 1 was uncertain.Six histories supported or confirmed BP-PVpatients with high abnormal oVEMP rates (5/6).Four in this 5 (80%)had abnormal oVEMP of the same MD ear.The single repositioning procedures can improve vertigo and eliminated positional nystagmus in cases of BPPV associated with MD.Conclusion In the present study,the prevalence of BPPV in patients with MD was 3 .45%.De-tailed medical histories combined with Dix-Hallpike and roll tests and VEMP tests can identify BPPV in patients with MD.

Prevalence of bilateral abnormalities of unilateral Meniére disease / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To analyze the abnormal conditions of the affected ear and the contralateral ear of patients with unilateral Meniere's disease and the prevalence of bilateral abnormalities among these unilateral Meniere disease population, providing reference for the clinical treatment strategies for Meniére disease.@*METHOD@#A retrospective analysis of 106 Meni6re disease cases was performed, the abnormal incidence of the affected ears, the contralateral ears and the bilateral abnormalities were calculated, and the disease characteristics were analyzed.@*RESULT@#The bilateral ears abnormal incidence of unilateral Meniére disease was 35. 85% (38/106); the cochlear symptoms of the contralateral ears often occurred 2. 25 years later of the symptoms of Meni6re disease; contralateral cochlear symptoms included at least two symptoms of tinnitus, deafness and ear fullness; 39. 47%(15/38) patients with bilateral abnormalities would appear binaural hearing impairment.@*CONCLUSION@#This study showed that about one-third of unilateral Meniére diseases have binaural symptoms, among which about one-third would occur bilateral hearing loss. Therefore, it is necessary to consider the course of disease and the symptoms of the contralateral ear before taking damage or destructive method for treating Meniére's disease clinically.

The roles of otolith organs in the recurrence primary benign paroxysmal positional vertigo / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the roles of otolith organs in the occurrence and recurrence of primary benign paroxysmal positional vertigo (BPPV) by vestibular evoked myogenic potential (VEMP) test.@*METHOD@#We enrolled 17 recurrent primary BPPV patients and 42 non-recurrent primary BPPV patients between September 2014 and November 2014. All patients underwent VEMP tests, including cervical vestibular evoked myogenic potential (cVEMP and ocular vestibular evoked myogenic potential (oVEMP) tests. The abnormal case was defined as non-elicitation or asymmetry rate between bilateral sides is larger than 29%.@*RESULT@#Significant difference was found in abnormal rate between cVEMP and oVEMP (P 0.05). No significant difference was found in sex and age between recurrent and non-recurrent groups (P > 0.05).@*CONCLUSION@#The impairment of otolith organs, especially the utricle, is related to primary BPPV. Dysfunction of utricle may play a role in recurrence of BPPV. Recurrence of BPPV is not correlated with sex and age.

The hearing and vestibular evoked myogenic potentials test in patients with primary benign paroxysmal positional vertigo / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the result of vestibular evoked myogenic potentials (VEMP) of primary benign paroxysmal positional vertigo(BPPV)and to identify the characteristics in VEMP examination of the primary BPPV and to observe the relevance of patients with primary BPPV and abnormal VEMP with hearing loss.@*METHOD@#Patients with primary BPPV were tested with pure tone audiometry, videonystagmograph and VEMPs test. We analyzed the difference in the two groups with normal hearing and hearing loss, discussed the etiology and pathogenesis.@*RESULT@#Primary BPPV comprised 23.0% with hearing lost, 77.0% hearing normal. The results of oVEMP were abnormal in 79. 7% (59/74) of the cases; and the results of cVEMP were abnormal in 66. 2% (49/74) of the cases; oVEMP and cVEMP differences to the diagnosis of primary BPPV (P<0. 05); oVEMP and cVEMP differences to the diagnosis primary BPPV with hearing lost (P<0. 05).@*CONCLUSION@#oVEMP detection positive rate of primary BPPV is higher than cVEMP,which may be due to otolithic particles falling from the utricle; positive rate of cVEMP in primary BPPV with hearing loss is higher than that of oVEMP, which may related to the cochlear and sacculus occured in the same embryonic tissue structure.

THE EFFECTS OF SODIUM SELENITE ON THE FUNCTION OF DENDRITIC CELLS FROM PERIPHERAL BLOOD OF CHRONIC HEPATITIS PATIENTS / 解剖学报

Objective To explore the methods of improving the immune function of dendritic cells(DCs) from patients with chronic type B hepatitis in vitro. Methods Monocytes from type B hepatitis patients and healthy controls were incubated with GMCSF and IL-4 and IFN-? to induce dendritic cells(DCs) generation.Then the nutrien-concentration sodium selenite was added for co-culture before the maturity of DCs.The samples were separated into three groups: hepatitis-B patients (group A),hepatitis-B patients with Se(group B),healthy control(group C).The phenotypes of DCs including CD80,CD86 were characterized by flow cytometry(FCM) and the response of allogeneic lymphocytes was detected by MTT assay.The concentration of cytokines in the supernatant such as IL-12 was tested by ELISA assay. Results After the nutrien-concentration Se was added for co-culture,the proliferation ability of isotype xenoma lymphocyte stimulated by DCs was obviously streng thened compared with group A,and the excretion level of IL-12 also increased(P
