OBJECTIVE To evaluate the status of the anxiety and depression in the inpatients of the otolaryngology with hospital anxiety and depression scale(HADs). METHODS A cross-sectional study was conducted from October 2014 to September 2016 at the Department of Otolaryngology, Affiliated Hospital of Yan'an University. We recruited 624 Chinese otolaryngology's inpatients to determine the prevalence of anxiety and depression using the HADs. HADs consists of 14 items, depression(seven items) and anxiety(seven times), each with four choices numbered alphabetically. Each of the subscales' scores ranges from 0 to 21, corresponding to total scores of 0 to 42, with higher scores indicating greater distress. Psychological distress was assessed for adult inpatients among the department of otolaryngology by a standardized HADs. In addition, the nasal bone fracture patients were treated as control and compared it to other diseases. Demographic data and clinical information collected from the patients and their hospital records were reviewed. RESULTS 1. Patients with sensorineural hearing loss, secretory otitis media, sudden sensorineural hearing loss, benign paroxysmal positional vertigo, peripheral facial paralysis, chronic sinusitis, polyp of vocal cord, laryngeal paralysis, fungal sinusitis and OSAHS revealed depressive and anxiety symptoms in comparison with the control. 2. Psychological distress of patients with sensorineural hearing loss and laryngeal paralysis were significantly related to education, which the anxiety or depression scores tended to increase with the education(P<0.05). CONCLUSION Depression and anxiety disorders were common in the local population of otolaryngology's inpatients. Recognizing the predictors for psychiatric morbidity could assist clinicians to identify those patients with a predisposition to developing psychiatric complications, and refer them for appropriate treatment. We recommend screening for psychological distress in patients with some otolaryngological diseases using a simple HAD tool to identify those patients who might benefit from a more psychologically based approach to therapy.

The result for statistical data analysis showed that the difference between oscillometric and auscultatory methods are quite small, and the accuracy of them are both quite good .This paper also previews the future of the noninvasive blood pressure measurement

Objective To investigate the therapeutic effects of recombinant yeast hepatitis B virus(HBV)vaccine combined with interferon(IFN)α-1b and determine the rational dosage of HBV vaccine for the further clinical study with larger sample.Methods Two hundreds and sixteen patients with chronic hepatitis B(CHB)were enrolled in this randomized,multi-center,double-blinded and placebo-controlled clinical trial.All the subjects were not treated with antiviral drugs within 6 months and randomly divided into 90μg,60μg and placebo groups with a ratio of 1:1:1.All the patients were intramuscularly administrated with 90μg or 60μg recombinant HBV vaccine or placebo at week 0,2,6,10,14,18,22,respectively.Meanwhile,they were also treated with IFNα-1b 50μg,3 times a wcek for 24 weeks.All patients were followed up for 24 weeks after withdrawal of anti-HBV therapy.Serum HBV DNA level,HBeAg titer and liver function were monitored frequently.Interferon-γ secreting lymphoeytes were detected by Enzyme-linked immunospot(ELISPOT)in part of the patients.Results The serum HBV DNA levels were(6.03±1.79),(5.52±1.82)and(6.29±1.70)log10 copy/mL at week 24 of treatment in high dose,low dose and placebo groups,respectively (P=0.458).And the serum HBV DNA levels were(5.92±1.98),(5.49±1.99)and(6.16±1.76)log10 copy/mL at weck 24 after withdrawal of treatment,respectively(P=0.720).The rates of patients whose HBV DNA＜1×105 copy/mL in these three groups were 30.4%,39.4% and 20.8% at week 24 of treatment,respectively and there was significant difference between high dose group and low dose group(P=0.015).The rate of patients whose HBV DNA＜1×105 copy/mL at week 24 after withdrawal was highest in low dose group,but no significant differences before and after treatment in these three groups(P=0.257).The HBV DNA negative rates were 17.4%,25.4% and 6.9% in these three groups,respectively,which were significantly different(P=0.012).At week 24 of treatment and week 24 after withdrawal of treatment,the alanine aminotransferase normalization rate,HBeAg seroconversion rate were highest in low dose group,but no significant differences in these three groups.ELISPOT positive rates at week 24 of treatment and week 24 after withdrawal of treatment in high close and low dose groups were higher than that in placebo group(P＜0.05).The incidence of adverse events was similar and there was no drug related severe adverse events in each group.Conclusion Recombinant HBV vaccine maybe contribute to anti-HBV therapy and 60μg of dosage seems to be rational.

Primers were synthesized according to DNA sequence of HBV found in China, and the reverse transcriptase (RT) region in polymerase gene, HBV preC/C region and the whole genome were amplified by PCR method from the serum of 8 patients with chronic HBV infection. Then the PCR products were ligated into pGEM Teasy vectors. 27 clones were sequenced. Deduced amino acid sequences were compared, and the results showed that mutations were widely distributed in structural and non structural viral proteins. The substitution mutations occur in clones isolated from specific patients, which led to a characteristic mutation in the quasispecies group. The results indicated that the diversity of HBV gene might play an important role in the pathogenesis of chronic HBV infection.
