Objective:To explore the clinical value of dynamic posturography in the diagnosis of peripheral vertigo. Method:One hundred and sixty peripheral vertigo patients with full clinical documents in vertigo clinic of our hospital from May 2007 to May 2008 were retrospectively analyzed in this study. All the patients firstly underwent the inspection of static and dynamic posturography and then were subjected to caloric test using videonystagmogra-phy. The results were conducted a comparative analysis. Surface of the statokinesigram (SSKG) was selected as assessment parameter of static posturography. The result of sensory organization test (SOT) were selected as assessment parameters of dynamic posturography. The unilateral weakness was selected as assessment parameter of caloric test. Twenty normal subjects were selected as control. Result: Among the 160 cases with peripheral vertigo, results of SOT in dynamic posturography were abnormal in 144 cases, with a sensitivity of 90. 0%; caloric test was abnormal in 110 cases, with a sensitivity of 68. 8%; static posturography was abnormal in 76 cases, with a sensitivity of 47. 5%. There existed a statistically significant difference between dynamic posturography and caloric test or static posturography. There were 40 patients(25. 0%) who had normal caloric test results in which dynamic posturograph findings were abnormal. Among the 20 cases of normal people, results of SOT in dynamic posturography were abnormal in only one case(5. 0%). Conclusion:With its superior sensitivity and specificity, dynamic posturography has been an objective and reliable approach in the diagnosis of peripheral vertigo. It can help to confirm the presence of abnormalities in some peripheral vertigo patients whose caloric results are normal.

Objective:To determine the effects of cognitive-behavioral therapy (CBT) on resting-state brain functional changes in adults with attention-deficit/hyperactivity disorder (ADHD).Methods:Participants including 10 adults with ADHD aged 18-65 years,diagnosed with the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-Ⅳ) and 12 age-and gender-matched healthy controls.The ADHD symptoms and executives functions were assessed using the ADHD Rating Scale (ADHD-RS) and Behavior Rating Inventory of Executive Function (BRIEF) respectively and resting-state functional magnetic resonance imaging were acquired before and after 12-session,CBT for ADHD patients.The healthy controls were also scanned.We used the regional homogeneity (ReHo) to capture the changes of regional brain function between pre-and post-CBT in ADHD for measuring the effects of CBT.Results:After CBT,the total scores of ADHD-RS [(43 ± 7) vs.(31 ± 7),P ＜ 0.01],the subscale of inattention and subscale of hyperactivity/impulsivity were decreased in ADHD adults.As for the executive functions,the subs cales of monitor [(15 ± 2) vs.(11 ± 2),P ＜ 0.01] and organization [(19 ± 5) vs.(14 ± 4),P ＜ 0.01] in BRIEF were reduced significantly in adults with ADHD after CBT training.The ReHo was increased in the regions involved in default mode network and fronto-parietal network,i.e.,right parahippocampa gyrus,fight precentral gyms,fight postcentral gyms and left postcentral gyrus (Voxels with P ＜ 0.05 and cluster size ＞3051mm3,which resulted in a corrected threshold of P ＜ 0.01 determined by AlphaSim).Conclusion:These findings support that CBT could selectively modulate the regional brain function in the default mode network and fronto-parietal network which may contribute to the improvement of ADHD symptoms and executive functions.

Objective To investigate the effect of arsenic trioxide (ATO) on the growth inhibition of bcr-abl mutant cell lines in vitro and to explore its potential mechanism. Methods The growth inhibition of ATO on bcr-abl wild type cell lines (K562, KBM5 and 32Dp210) and imatinib(IM)-resistant cell lines (K562R, KBM5R, 32Dp210T315I, 32Dp210Q252H, 32Dp210Y253H, 32Dp210M351T and 32Dp210E255K) were measured by trypan blue exclusion. Apoptosis was assayed by AnnexinV and PI staining. Glutathione (CSH) levels were detected by DTNB colorimetry of Glutathione Assay Kit. Results ATO inhibited cell growth in both bcr-abl wild type and IM-resistant mutant type cells in a dose dependent manner. ATO significantly inhibited growth of bcr-abl point mutant cells compared with the corresponding wild type cells, and the IC50 of ATO in mutant cells was lower than that in wild type, while the IC50 in no point mutant cells K562R was not different compared with that in wild type cells K562. The GSH levels in bcr-abl point mutant cells were lower than that in the corresponding wild type cells(P =0.00106-0.0358) , but that in K562 was quite similar with K562R cells(P = 0.315). After depletion of intracellular GSH by using BSO, the growth inhibition of ATO in both bcr-abl point mutant cells and wild type cells was significantly enhanced. Conclusion The growth inhibition of ATO on bcr-abl point mutant cells is remarkably more effective than that on wild type cells, which may be related with intracellular GSH. ATO would be a potential therapeutic select against CML with bcr-abl point mutation including the T315I mutation.

Objective To investigate the efficacy and safety of vasopressin receptor antagonist tolvaptan for treating dilutional hyponatremia casused by decompensated liver cirrhosis.Methods Ninety-six subjects with decompensated liver cirrhosis complicated by dilutional hyponatremia were divided into test group (n =56) and control group (n =40) by double blind method.Test group were treated with a single dose of tolvaptan 15 mg orally in addition to routine therapy,while control group were treated with routine therapy plus placebo.The changes in serum sodium concentration,liver functions,ascites,and edema of lower extremities between the two groups were observed.Measurement data were compared by t test,and categorical data were compared by chisquare test.Results On day 7,36 (64.3％) patients in test group and 9 (22.5％) patients in control group reached normal serum sodium concentrations (x2 =5.241,P＜0.01).All the patients in test group and only 3 patients in control group had 24 hours' total urine volume above 3500 mL.Difference of 24 hours' total urine volume during 7-day treatment between the two groups was statistically significant (t=20.899,P＜0.01).Thirty-nine patients in test group and 15 patients in control group had reduced ascites (x2 =4.260,P=0.039),but improvement of edema in lower extremities of both groups was comparable (12 cases in test group and 7 cases in control group; x2 =0.227,P=0.634).Serum alanine aminotransferase (ALT),total bilirubin (TBil),potassium and creatinine levels of test group were improved after treatment,but were not significantly different from either baseline levels (t=1.509,0.783,1.107,1.237; both P＞0.05) or those of the control group (t=1.712,1.635,1.121,0.873; both P＞0.05).Conclusions Single dose of tolvaptan (15 mg) exerts a strong diuretic effect and is able to greatly increase serum sodium concentration,thus has distinct therapeutic effect for patients with decompensated liver cirrhosis complicated by dilutional hyponatremia.

ObjectiveAfter intratympanic gadolinium administration through the tympanic membrane,three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI) was performed to evaluate endolymphatic visualization and its diagnostic value in Meniere's disease.MethodsTwenty-four hours after intratympanic gadolinium administration through the tympanic membrane,19 patients with unilateral Meniere's disease diagnosed clinically underwent 3D-FLAIR and 3D-Balance-FFE imaging at 3.0 T MR scanner.The enhanced imaging of perilymphatic space in bilateral cochlea,vestibular and (or) canal were observed.Scala tympani and scala vestibule of bilateral cochlear basal turn were scored respectively.The enhanced range of bilateral vestibule and the signal intensity ratio (SIR) between the vestibule and the brain stem were measured. Wilcoxon tests and paired t tests were used.ResultsThe gadolinium appeared in almost all parts of the perilymph in cochlea,vestibular and (or) canal,so the endolymphatic space was clearly visualized on 3D-FLAIR imaging.The score of scala vestibuli between the affected side (3 cases scored 2,9 cases scored 1,7 cascs scored 0) and the healthy side ( 15 cases scored 2,2 cases scored 1,2 cases scored 0 ) were significantly different ( U =3.090,P ＜ 0.05 ).The area of enhanced vestibular were (5.77 ± 2.33) mm2 and (8.11 ± 3.32) mm2 for the affected side and the healthy side,which were significantly different ( U =3.090,P ＜ 0.05 and t =2.638,P ＜ 0.05 ).Conclusions According to 3D-Balance-FFE MRI and the enhancement of perilymphatic space,3D-FLAIR MRI with intratympanic gadolinium injection through the tympanic membrance can be used to show the border between the perilymph and the endolymph and confirm endolymphatic hydrops,thus providing radiographic evidence for the diagnosis of Meniere's disease.

Objective To evaluate the feasibility,safety and efficacy of ESD for precancerous lesions and early cancer of remnant stomach after partial gastrectomy.Methods ESD was performed in 11 cases of high grade intraepithelial neoplasia/early cancer of remnant stomach.The short-term and long-term indices including time of procedure,complication,En Bloc resection rate,R0resection rate,local recurrence rate as well as lymph node metastasis were recorded and analysed.Results ESD was completed in all patients with only one case of delayed massive bleeding which was controlled by endoscopy successfully.Average procedure time,En Bloc resection rate,R0 resection rate were 85.5 minutes,100％ and 90％,respectively.No local recurrence or lymph node metastasis was detected during post-ESD surveillance (15 ～ 51 months).Conclusion High grade intraepithelial neoplasia and early cancer of remnant stomach after partial gastrectomy might be indication for ESD because of its safety and definite effect.Additionally,careful management of the fibre tissue is the key to procedure success.

OBJECTIVE: To explore the factors related to the occurrence of otitis media with effusion (OME) in patients with long-term tracheal intubation. METHOD: This retrospective study included 47 cases with endotracheal intubation more than 7 days (endotracheal intubation group) and 20 cases without mechanically ventilated in the same period(control group). The relationships between secretory otitis media with age, gender, intubation method,duration of intubation, breathing patterns, consciousness, gastric tube position were analysed. RESULT: The study showed 27 out of 47 patients in endotracheal intubation group had OME, 9 cases had negative pressure in the middle ear and 11 patients were normal. No OME was found in control group, and 2 cases with negative pressure in bilateral middle ear were detected. The incidence of OME was significantly increased in patients with the application of ventilator in PEEP mode or nasotracheal tube, and with conscious disturbance or tracheal intubation using for more than 10 days. The presence of OME had a significantly higher rate in patients with nasal intake subjects than the oral intake subjects. The incidence of OME decreased significantly in patients using glucocorticoid. CONCLUSION The incidence of OME increased in patients applied with tracheal intubation for more than 7 days. Ventilator in PEEP mode, nasotracheal tube, and conscious disturbance were closely related with OME. Application of glucocorticoids reduced the incidence of OME.
