ABSTRACT
Abstract Introduction The Epley maneuver is useful for the otoconia to return from the long arm of the posterior semicircular canal into the utricle. To move otoconia out of the posterior semicircular canal short arm and into the utricle, we need different maneuvers. Objective To diagnose the short-arm type BPPV of the posterior semicircular canal and treat them with bow-and-yaw maneuver. Methods 171 cases were diagnosed as BPPV of the posterior semicircular canal based on a positive Dix-Hallpike maneuver. We first attempted to treat patients with the bow-and-yaw maneuver and then performed the Dix-Hallpike maneuver again. If the repeated Dix-Hallpike maneuver gave negative results, we diagnosed the patient with the short-arm type of BPPV of the posterior semicircular canal and considered the patient to have been cured by the bow-and-yaw maneuver; otherwise, probably the long-arm type BPPV of the posterior semicircular canal existed and we treated the patient with the Epley maneuver. Results Approximately 40% of the cases were cured by the bow-and-yaw maneuver, giving negative results on repeated Dix-Hallpike maneuvers, and were diagnosed with short-arm lithiasis. Conclusion The short-arm type posterior semicircular canal BPPV can be diagnosed and treated in a convenient and comfortable manner.
Resumo Introdução A manobra de Epley é útil para o retorno da otocônia do braço longo do canal semicircular posterior para o utrículo. Diferentes manobras são necessárias para mover a otocônia para fora do braço curto do canal semicircular posterior e para dentro do utrículo. Objetivo Diagnosticar a VPPB do tipo braço curto do canal semicircular posterior e tratá-la com a manobra de incline and balance. Método Foram diagnosticados 171 casos como VPPB de canal semicircular posterior com base na manobra de Dix-Hallpike positiva. Primeiro tentamos tratar os pacientes com a manobra de incline and balance e, em seguida, executamos a manobra de Dix-Hallpike novamente. Se a repetição da manobra de Dix-Hallpike desse resultados negativos, diagnosticávamos o paciente como VPPB do canal semicircular posterior do tipo braço curto e considerávamos que ele ou ela havia sido curado pela manobra de incline and balance; caso contrário, provavelmente o paciente apresentava VPPB do canal semicircular posterior do tipo braço longo e tratávamos o paciente com a manobra de Epley. Resultados Aproximadamente 40% dos casos foram curados pela manobra de incline and balance, com resultados negativos nas manobras de Dix-Hallpike repetidas, e foram diagnosticados com litíase de braço curto. Conclusão A VPPB de canal semicircular posterior do tipo braço curto pode ser diagnosticada e tratada de maneira conveniente e confortável.
ABSTRACT
ObjectiveEndobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) examination is a new bronchoscopy for early diagnosis and staging assessment of lung cancer, however it often makes patients scared and worried because of penetration and irritation brought by the operation. The article aimed to investigate the health education need of patients and analyze its influencing factors in order to provide evidence for pointed health education and successful examination.MethodsA self-designed questionnaire was used to investigate 100 patients with EBUS-TBNA at Thoracic Surgery Department in our hospital, from December 2016 to August 2017. Data were analyzed by SPSS 20.0 software.ResultsThe average score of health education need for patients undergoing EBUS-TBNA examination was (68.83±9.80). Single factor analysis showed there were differences in the scores of patients' ages, jobs, educational levels and medical insurance payment methods(P<0.05). Multiple linear regression analysis showed the influencing factors included educational level, age and medical insurance payment method, which could explain the mutation value 0.189. The average score of health education need was (13.84±1.30), including listening to professional explanation (4.64±0.58), watching operation video(4.61±0.53) and reading education brochures(4.59±0.60).ConclusionPatients have high health education need for EBUS-TBNA examinations and clinical staff should provide normalized health education pathway based on the patients' needs and improve the satisfaction of examination.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between 5-HTTLPR and/or DRD4 gene polymorphisms and the accident tendentiousness of drivers.</p><p><b>METHODS</b>A case-control study, including 42 patients and 46 controls, were performed using type-A behavior questionnaire and EPQ scale. 5-HTTLPR and DRD4 gene -521 C/T were detected by the PCR-RFLP technique.</p><p><b>RESULTS</b>The scores of type-A behavior questionnaires, such as TH and TH + CH in exposure group were significantly higher than those in control group (P < 0.05). P and N scores of EPQ questionnaires in exposure group were significantly higher than those in control group, and L score in exposure group was significantly lower than that in control group (P < 0.05 or P < 0.01). There were significant differences in the frequencies of the genotypes and alleles of 5-HTTLPR gene between the cases and the controls (P < 0.05), but there were no significant differences in the frequencies of the genotypes and alleles of DRD4 gene between the two groups (P > 0.05). In the drivers with the accident tendentiousness, P scores in the cases with homozygous genotypes of the S/S in 5-HTTLPR gene were significantly higher than those in the cases with the genotypes of S/L and L/L in 5-HTTLPR gene (P > 0.05). E scores in subjects with homozygous genotypes of the T/T in DRD4 gene were significantly higher than those in subjects with genotypes of the T/C+C/C in DRD4 gene (P > 0.05).</p><p><b>CONCLUSION</b>The driver accident tendentiousness may be associated with 5-HTTLPR gene, but not associated with DRD4 gene. The two genes are associated with the type-A behavior and personality characteristics of drivers with accident tendentiousness. However, 5-HTTLPR and DRD4 gene may not have synergism in these behaviors and personality.</p>

<p><b>OBJECTIVE</b>To evaluate the gene-chip detecting rifaman-resistance Mycobacterium tuberculosis applied in TB diagnosis and drug-resistant detection.</p><p><b>METHODS</b>Mycobacterium tuberculosis and rifaman-resistant strains among 35 rifaman-resistance isolated strains and 102 sputa specimens from TB patients, 27 sputa specimens from other patients were examined the gene-chips. Results obtained were compared with sputum examination, bacteriological culture and standard drug susceptibility test of Mycobacterium tuberculosis.</p><p><b>RESULTS</b>Thirty-five rifaman-resistance strains were detected by gene-chips and 33 were identified as rifaman-resistance strains and the concordance with the traditional drug susceptibility test of Mycobacterium tuberculosis was 94.29%. Twenty-seven sputa specimens from other patients were examined Mycobacterium tuberculosis by the gene-chips, 2 were positive, the detection specialty was 92.59%. Using three methods detecting Mycobacterium tuberculosis among 102 sputa specimens the positive rate respectively was, sputum examination 35.29% (36/102), bacteriological culture 28.43% (29/102), gene-chip 77.45% (79/102). Among 102 sputa specimens only 29 examined Mycobacterium tuberculosis by the traditional drug susceptibility test and 8 were rifaman-resistant strains. While using gene-chip, there were 20 among 102 sputa specimens identified as rifaman-resistance strains. Among total 55 rifaman-resistance strains detected by the gene-chips, the most frequent mutations were those associated with codon 531 (23 of 55; 41.8%), 526 (15 of 55; 27.27%) and 516 (9 of 55; 16.36%).</p><p><b>CONCLUSION</b>Results showed that this was a rapid, simple and highly specific method when using gene-chip to detect Mycobacterium tuberculosis and rifaman-resistant strains.</p>
