The purpose of this study was to assess the diagnostic value of main frequency of transient evoked otoacoustic emissions for Meniere's disease. The click- evoked transient otoacoustic emissions(TEOAE) in normal subjects and in patients with Meniere' s disease were examined using ILO 88 otodynamic analyzer system to observe the main frequency distrbution. The main frequeencies ranged from 1.2 to 1.6 kHz in normal ears, and from 0.8 to 1. 1 kHz in Meniere' s ears. The main frequency range of normal ears was obviously higher than that in Meniere's ears. After application of glycerol, the main frequencies in some Meniere's ears were shifted from relative low frequency range to relative high frequency range. TEOAE appeared in some Meniere's ears in which TEOAEs could not be evoked before application of glycerol. The results suggest that the TEOAE can be used in the diagnosis of Meniere's disease.

Objective To explore the value of microarousal in the diagnosis and treatment of obstructive sleep apnea-hypopnea syndrome(OSAHS). Methods 120 snorers were monitored by standard polysomnography(PSG). The overnight PSG recordings were also performed 1 year after operation in 24 patients, who had filled in the Epworth Sleep Score(ESS) before and after treatment, to evaluate the improvement of daytime sleepiness. Results After operation, obstructive sleep apnea of the 24 patients disappeared, their ODI 4 decreased from (52?26)/h to (10?8)/h, microarousal decreased from (28?16)/h to (14?6)/h, and the subjective and objective daytime sleepiness was improved. Conclusion The EEG changes of microarousal with at least 3 seconds in OSAHS patients can be recorded by computerized EEG analysis. Microarousal can serve as an index for daytime sleepiness, and be complementary to AHI in the diagnosis and treatment of OSAHS.

ObjectiveTo observe the effect of the doctor-led telephone interview on the state of anxiety for outpatients with epilepsy.Methods100 outpatients with epilepsy and state of anxiety were divided into two groups: intervention group (doctor-led telephone interview) and control group (outpatient face-to-face visit in the epileptic clinic), 50 cases in each group. Doctor-let semi-structured telephone interview was performed in the intervention group, while routine face-to-face interview in outpatient was performed in the control group for 6 months. Self-rating Anxiety Scale (SAS) was used to assess the anxiety state before and 6 months after intervention. The state of anxiety and the patients' contents in the two groups were analyzed.ResultsThe scores of SAS in two group decreased 6 months after intervention and the intervention group was better than the control group.ConclusionThe doctor-led telephone interview can improve the state of anxiety for the patients with epilepsy.

ObjectiveTo assess the relationship of filaggrin expression with atopic diathesis and disease severity in patients with alopecia areata (AA).MethodsThirty-seven patients with AA aged (26.3 ± 10.6) years were enrolled in this study.Atopic diseases were noted in 8 of these patients.Clinical data and laboratory test resuhs were reviewed.Immunohistochemical staining was performed to quantify the expression of filaggrin protein in scalp biopsy specimens from all of the 37 patients with AA and from 10 human controls,and fluorescence-based semiquantitative reverse transcription-PCR to detect the expression of filaggrin mRNA in scalp biopsy specimens from 22 patients with AA and 13 healthy controls.Data were statistically analyzed by Mann Whitney U test,chi-square test,and Spearman's rank correlation test.ResultsThe expressions of filaggrin protein and mRNA were significantly lower in patients with AA than in the controls(P < 0.05 or 0.01 ),and the decrease seemed more obvious in patients with large areas of lesions,long duration of disease,and nail abnormalities,but the degree of decrease was unrelated to the complication with atopic diseases.No significant differences were observed in sex ratio,age at onset,disease duration,area of hair loss,the prevalence of family history or incidence of nail abnormalities and increase in serum IgE and eosinophils,between patients with atopic diseases and those without.ConclusionsThe expressions of filaggrin protein and mRNA are decreased in patients with AA,suggesting that filaggrin may participate in the development of AA and is correlated with the severity of AA.

Objective To investigate the clinical,histopathological and dermoscopic features as well as treatment and prognosis of cicatricial alopecia.Methods Clinical data on 53 patients with cicatricial alopecia were retrospectively collected and studied.Pathological and dermoscopic characteristics,as well as treatment modality and prognosis of cicatricial alopecia were analyzed.Results Cicatricial alopecia was characterized by alopecia,disappearance of follicular ostia,and absence or decrease in the number of polisebaceous gland units.Pathologically,focal liquefactive degeneration of basal cells,follicular keratotic plugs,arborising telangiectasia together with a positive immunofluorescence test were usually suggestive of discoid lupus erythematosus,interface dermatitis suggestive of lichen planopilaris,inflammation and mild disruption of elastic fibers suggestive of classic pseudopelade of Brocq.Mucin deposition between hair follicles and sinking of follicular ostia were pathological and dermoscopic characteristics of alopecia mucinosa.Pustules could be visible in both folliculitis decalvans and dissecting cellulitis/folliculitis,with tufted hairs usually seen in the former,and sinus formation in the later.Lymphocytic disorders were treated with immunosuppressors,and neutrophile disorders with antibiotics and retinoids.Conclusions Histopathological examination plays a determinant role in the diagnosis of cicatricial alopecia,which can cause irreducible damage to hair follicles,and require long term treatment.Early diagnosis and appropriate use of drugs may control the development of cicatricial alopecia,and reduce the occurrence of permanent hair loss.

Objective To evaluate the value of serum procalcitonin (PCT)on antibiotic use in treatment of community acquired pneumonia (CAP) in outpatient. Methods From November 2006 to February 2008, a total of 127 patients with CAP in outpatient were randomly assigned into two groups:PCT group(n=63)and control group(n =64). PCT levels of all patients were measured after study admission. On the base of similarly normal treatment, the control group received antibiotics according to the attending physicians and the PCT group were treated with antibiotics according to serum PCT levels: antibiotic treatment was applied with PCT level ≥ 0. 25 μg/L and was discouraged with PCT level < 0.25 μg/L. Clinical efficacy, rate of antibiotics use, duration courses and costs of antibiotics were observed. Results Clinical efficacy of the PCT group was similar with the control group (92.1% vs 87.5%, P >0.05) ;rate and costs of antibiotics use was lower, antibiotic duration of the PCT group was shorter than that ofthecontroigroup(P<0.05,P<0.001,P<0.001).Conclusion PCT could be used in treatment of CAP for antibiotic use in outpatient, which may reduce antibiotic use, shorten antibiotic duration and lower costs of antibiotic.

Objective To investigate the clinical effects and advantages of flexible 3D laparoscopic surgery on rectal cancer after neoadjuvant chemoradiotherapy (nCRT). Methods The data of 152 patients who received laparoscopic rectal cancer resection after nCRT excluding the cases of high rectal cancer, cardiac and pulmonary dysfunction were analyzed from January 2015 to January 2016 in the Department of Colorectal Surgery of Liaoning Cancer Hospital. The distances from the annal edge to the inferior tumor margin were within 8 cm in these patients. Among these patients, 76 cases received the 3D laparoscopic surgery after nCRT (3D-nCRT), and 76 cases undergone the 2D laparoscopic surgery after nCRT (2D-nCRT). Results Between two groups, the number of lymph node harvest (14.8±2.1 vs. 14.3±1.7), positive rate of the distal margin [1.3 % (1/76) vs. 2.6 % (2/76)], reserving anus rate [92.1 % (70/76) vs. 81.2 % (67/76)], local recurrence rate [1.3 % (1/76) vs. 3.9 % (3/76)] and anastomotic leakage rate [2.6 % (2/76) vs. 3.9 % (3/76)] had no statistical differences (all P>0.05), while the operative time [(125.3±10.2) min vs. (136.6±12.0) min], intraoperative bleeding [(54.1±23.2) ml vs. (61.9±19.5) ml], anus exhaust time [(43.5±5.0) h vs. (45.4±5.6) h] and positive rate of circumferential resection margin (CRM) [1.3 % (1/76) vs. 9.2 % (7/76)] had statistical differences (all P< 0.05). Conclusion Flexible 3D laparoscopic surgery on rectal cancer after nCRT can shorten operative time, reduce intraoperative bleeding, alleviate the influence of intestinal peristalsis function, and improve operative quality.
