OBJECTIVE To retrospectively analyze the clinical characteristics of the benign paroxysmal positional vertigo (BPPV) secondary to the sudden deafness (SD) and to explore the possible pathogenetic mechanism, diagnosis and treatment. METHODS 218 cases of the SD in our department were retrospectively analyzed, and 37 patients with primary BPPV during the same period were used as control group. All patients were confirmed by the examination of Dix-Hallpike and the roll check,the primary disease (sudden deafness) of secondary BPPV patients were in line with the Chinese Medical Association diagnostic criteria. RESULTS In all these patients with SD,there were 91 cases with BPPV secondary to the SD. There were 67 cases of BPPV of posterior semicircular canal and 21 cases of BPPV of lateral BPPV semicircular canal. Besides, 3 cases were of multi-semicircular canal affected. All patients with BPPV were diagnosed as the same ears as the SD. The symptoms were alleviated and initial success rate was 68.1%. During 6-22 month follow-ups, total success rate was 100%, and recurrence rate was7.7% (7/91). The hearing recovery of high frequency is worse than that of the low frequency. There were 2 cases of recurrence in lateral BPPV group, 5 cases in posterior BPPV group. All were cured by reposositioning maneuver. All patients with primary and secondary BPPV were cured with Epley maneuver or Barbecue roll maneuver, and the curative effect of them is similar. CONCLUSION The occurrence of BPPV may follow SD,and the majority of BPPV secondary to the SD occurs in the posterior semicircular canal. The canalith repositioning is an effective therapy for secondary BPPV.

Hepatitis B virus (HBV)-related liver failure is an end-stage liver disease with a high mortality.Biomarkers,which are of interest,are helpful for diagnosis and treatment of liver failure.The purpose of this review is to highlight the recent advances in this field.Although many new biomarkers can improve the prognostic efficacy,the dynamic biochemical function of liver and kidney as well as the function of coagulation are still the most practical and common indexes for the development and prognosis evaluation of liver failure.

Objective To explore the effects of low frequency electric stimulation on the clinical manifes- tation and its influence on the level of plasma Endothelin (ET),atrial natriuretic peptide (ANP),thromboxane B_2 (TXB_2),angiotensinⅡ(AngⅡ),Calcitonin Gene Related Peptide(CGRP) and Neuron-specific Enolase(NSE) and its clinical significance in the patients with vertebrobasilar insufficiency(VBI). Methods One hundred and tewenty cases of VBI patients were randomly divided into two groups:a treatment group and a control group.Both groups received routine drug treatment.The treatment group (n=60) was also treated with low frequency electric stimulation at bilateral mastoid processfes in addition.The improved rate of the clinical symptom,the plasma level of ET,ANP,TXB_2,AngⅡ,GRP and NSE were observed after treatment. Results The patients treated in the treatment group had significantly better outcome than the control group in terms of symptom relief.The effective rate was 87.93% and 67.80% in the treatment group and control group,respectively(P

?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.
