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

Objective:To analyze the relationship of lipoprotein associated phospholipase A 2 (Lp-PLA2) and severity of coronary atherosclerosis, and evaluate the effects of rosuvastatin at different doses on the concentration of plasma Lp -PLA2.Methods: Totally 152 cases of patients with suspected coronary heart disease were treated with coronary angiography .According to the results of angiogra-phy, the patients were divided into the coronary heart disease group ( n=117 ) and the normal control group ( without coronary heart disease,n=35).Gensini integral scale was performed and referring to the number of diseased coronary arteries , the degree of coronary atherosclerosis was evaluated .The concentration of serum Lp-PLA2 was detected and the relationship of Lp-PLA2 and the severity of coronary plaque was evaluated .Meanwhile , the patients with coronary heart disease were divided into 2 groups and orally treated with rosuvastatin respectively at the routine dose (10 mg· d-1 ) and the loading dose (20 mg· d-1 ).The changes of the plasma concentra-tion of Lp-PLA2 before the treatment, in the 2nd, 4th,8th and 12th week after the medication were measured and the effect of atorvastatin at different doses on the plasma concentration of Lp-PLA2 was summarized .Results: The plasma Lp-PLA level in the control group was (22.22 ±1.75) μmol· ml-1, while that in the coronary heart disease group was (29.03 ±3.99) μmol· ml-1(P<0.05).The differences in Lp-PLA2 levels between the groups with different Gensini scores of coronary heart disease were statistically significant ( P<0.05).The higher scores were, the higher Lp-PLA2 levels were.The results of multivariate analysis showed that the severity of cor-onary atherosclerosis was significant and positive correlated with Lp-PLA2 level (OR=1.613,P<0.05).In the 2nd, 4th, 8th and 12th week after the medication , Lp-PLA2 levels in the loading dose group were significantly lower than those in the routine dose group ( P<0.05).In the 2nd, 4th, 8th and 12th week after the medication, the degree scores of coronary artery stenosis in the loading dose group were reduced.The decreasing range was significantly greater than that in the routine dose group (P<0.05).The incidence of adverse cardiovascular events in the routine dose group (27.12%) was significantly higher than that in the loading dose group (6.90%) ( P<0.05).The incidence of adverse drug reactions in the routine dose group was 11.86%, while that in the loading dose group was 18.97%(P>0.05).Conclusion:Lp-PLA2 is correlated with the severity of coronary plaque .High dose of rosuvastatin can reduce plasma Lp-PLA2 concentration in the patients .

Objective To evaluate the cost-effectiveness of entecavir and lamivudine in treatment of early stage acute on chronic liver failure (ACLF),and analyze the predictive factors.Methods Forty nine patients with early ACLF were enrolled.Of which,28 patients were treated with entecavir,and 21 patients were treated with lamivudine.Mortality,length of hospital stay,cost,liver function,coagulation function,and model for end-stage liver disease (MELD) score were compared between two groups.Pharmacoeconomic evaluation was taken using cost-effectiveness analysis and cost minimization analysis.Results Mortality,length of hospital stay and cost had no significant difference between two groups.Ratio of costeffectiveness in lamivudine group was higher than that in entecavir group.Cox analysis showed that primary peritonitis and MELD score at the end of the second week were the main predictive factors.Conclusions Entecavir cannot improve the survival rate of early stage ACLF compared to lamivudine,but may provide economic benefit to patients with early stage ALCF.

Genechip was applied to explore gene expression profile of islets in rats at various stages of pregnancy. Compared with the normal control group, differential expressions of hundreds of genes were detected during pregnancy. Reg3α gene expression was markedly increased during pregnancy, which may be related to islet regeneration.

In order to enhance the specificity of TNF-α monoclonal antibody to inflamed site, a bispecific antibody BsDb that targets TNF-α and the extra-domain B (ED-B) of fibronectin (FN) was constructed by covalently linking the anti-TNF-α single chain Fv antibody (TNF-scFv) and the anti-ED-B scFv L19 via a flexible peptide linker deriving from human serum albumin (HSA). ED-B is an antigen specifically expressed at the inflamed site. BsDb is expressed in E. coli, identified by immunoblot, and purified with affinity chromatography. This was followed by further examination of its bioactivities and pharmacokinetics. We demonstrated that BsDb retained the immunoreactivity of its original antibodies as it could simultaneously bind to TNF-α and ED-B and neutralize the biological action of TNF-α. In the collagen-induced arthritis mice model, BsDb selectively accumulate in the inflamed joint with a maximal uptake of (12.2 ± 1.50)% ID/g in a single inflamed paw and retain in the inflamed paw for at least 72 h. In contrast, BsDb showed a short serum half-life of (0.50 ± 0.05) h and a rapid clearance from normal tissues. The findings reported herein indicate that BsDb has good specificity to the inflamed site and low toxicity to normal tissues. BsDb is therefore likely to have greater clinical applications in the treatment of rheumatoid arthritis and other autoimmune diseases. This laid a stable basis for its preclinical study.
