OBJECTIVETo explore the diagnostic value of pulse transit time (PTT) in children with sleep disordered breathing(SDB).
METHODSForty eight randomly selected snorers (2 - 13 years) with SDB were examined by PSG and PTT in the same time. Data obtained were analyzed by different technicians respectively. Statistics and analysis of the data were performed.
RESULTSApnea hypopnea index (AHI), obstructive apnea index (OAI), the lowest oxygen and micro-arousal index were obtained by PSG and PTT. The results was described as M [25 percentile; 75 percentile]: 4.9[1.3;10.1], 4.6[1.5;11.8]; 1.2[0.7;4.9], 1.3[0.6;5.0]; 0.93[0.85;0.95], 0.93[0.84;0.95]; 14.5[12.6;16.4], 26.0[17.4;30.6]. The difference of AHI, OAI, and the lowest oxygen were not significant (P > 0.05), while the PTT arousal index detection rate was higher than PSG (Z = -5.19, P < 0.01). There was no significant difference in the diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS) and determination of degree of patient's condition (P > 0.05). PTT could identify upper airway resistance syndrome in children without OASHS.
CONCLUSIONSBoth methods can be used to diagnose SDB. However, PTT is easy to use and suitable for the diagnosis of SDB in children, especially for UARS.

OBJECTIVEUsing olfactory event related potentials (OERP) and magnetic resonance to evaluate olfactory function in patients with posttraumatic anosmia.
METHODSTwenty four patients with posttraumatic anosmia were reviewed retrospectively. A thorough medical history, physical examination, nasal endoscopy, T&T olfactory testing, olfactory event-related potentials, brain computed tomography scan and magnetic resonance image of olfactory pathway were performed in all patients.
RESULTSSubjective olfactory testing indicated 20 of 24 patients were birhinal anosmia, 2 with right nostril anosmia and left impairment, 2 with left anosmia and right normal. No OERP were obtained in 24 (20 were birhinal, 4 was monorhinal), except 4 cases with single nostril. Magnetic resonance imaging revealed the injures to the olfactory bulbs (100%), rectus gyrus (91.7%), orbital gyrus (67%), olfactory tracts (8%) and temporal lobes (8%).
CONCLUSIONSOERP can objectively evaluate posttraumatic olfactory function, and magnetic resonance of olfactory pathway can precisely identify the location and extent of injures.

OBJECTIVETo analyze the similarities and differences of the clinical manifestations between the children with upper airway resistance syndrome (UARS) and obstructive sleep apnea-hypopnea syndrome (OSAHS), and to explore the clinical features and characteristics of sleep respiratory parameters.
METHODSUsing the double-blind method, all children were diagnosed as UARS or OSAHS through the polysomnography test and the results of all children were analyzed by a sleep technician and an otolaryngologist. Another ENT doctor recorded their clinical and physical examination in detail.
RESULTSPolysomnography showed that the apnea-hypopnea index (AHI) and the lowest oxygen in 253 children with OSAHS were 3.60[2.00;7.55] times/h and 0.90[0.85;0.91], and were 0.90[0.50;1.10] times/h and 0.95[0.92;0.96] in 102 children with UARS, the difference of the two groups by rank test was statistically significant. The proportion of UARS and OSAHS was more common during preschool period than during school-age period. The chief complaint in two groups was sleep snoring, and the main symptoms were sleep restless, attention deficit/hyperactivity and breath with mouth open. The incidence rate of above symptoms were as follows, 94.1%, 72.5%, 62.7% and 37.3% in children with UARS, 92.9%, 78.7%, 57.7% and 45.5% in children with OSAHS. The difference was not significant by chi-square test (P>0.05). Tonsil and adenoid hypertrophy were also observed in the two groups, the difference was not significant (chi2 = 0.27, P= 0.87). However, the children with OSAHS were more apt to have the sleep apnea than with UARS, the difference was statistically significant (chi2 = 34.07, P<0.001).
CONCLUSIONSThe clinical manifestations of two groups are similar, the difference between UARS and OSAHS can not be determined by the patient's clinical performance. Sleep apnea can be more easily observed in children with OSAHS than that in UARS, the final diagnosis is based on polysomnography.

To investigate JAK2V617F mutation and its clinical significance in patients with idiopathic myelofibrosis (IMF), genomic DNA was extracted from peripheral blood cell samples of 12 IMF cases. Allele-specific PCR (AS-PCR) was performed to identify JAK2V617F mutation, and the results were confirmed by sequence analysis. A retrospective study was performed to explore the correlation between JAK2V617F mutation and the clinical, hematologic features. The results showed that in follow-up for 2 to 15 months, the occurrence of the positive point mutation in 12 patients with IMF was 50%, and the half of these positive patients had thrombosis. Patients with JAK2V617F point mutation had a higher counts of platelets and megakaryocytes in bone marrow than those in patients without JAK2V617F point mutation. Out of other 6 IMF patients without JAK2V617F point mutation only 1 patient had thrombosis, and lower counts of platelets in peripheral blood and megakaryocytes in bone marrow. It is concluded that majority of IMF patients with positive JAK2V617F point mutation have typical clinical and hematologic features, higher incidence of thrombosis, and higher counts of platelets in peripheral blood and megakaryocytes in bone marrow.

OBJECTIVETo investigate the value of incidental focal (18)F-FDG uptake in the colon and rectum and characteristics of functional anatomic form for differential diagnosis of colorectal benign or malignant diseases.
METHODSClinical data and images of incidental focal hypermetabolism focus in colon and rectum of 37 individuals undergoing (18)F-FDG PET-CT were analyzed retrospectively. According to the eventual outcomes of pathological examination and clinical follow-up, these cases were divided into four subgroups: malignant disease, benign tumor (including precancerous change), inflammation and physiological uptake. Radioactive uptake level (SUVmax) and change of delayed imaging (RI) of focal hypermetabolism focus were compared between groups. The data analysis was performed using variance analysis.
RESULTSThe average SUVmax was 6.3±3.7, 8.8±6.5, 5.2±1.4, and 3.8±0.9 in malignant disease (n=11), benign (precancerous) tumor (n=9), inflammation (n=9) and physiological uptaking (n=8) respectively. The average SUVmax was 7.6±5.6 in benign and malignant tumor, and 4.7±1.5 in inflammation and physiological uptake. The distinction of average SUVmax was not statistically significant between benign and malignant tumor or inflammation and physiological uptake. But it was higher in tumors as compared to inflammation or physiological uptake with a statistically difference (P<0.05). The RI was 0.3±0.2, 0.4±0.1, 0.3±0.2, 0.4±0.2 in above 4 groups respectively, and the differences were not statistically significant.
CONCLUSIONSThe incidental focal hypermetabolism focus in the colon the rectum during (18)F-FDG PET-CT may indicate potential colorectal malignant diseases and precancerous lesions. SUVmax value in focal hypermetabolism focus in the colon and rectum can help to distinguish tumor from inflammation or physiological uptake. But there is no diagnostic value for distinguishing malignant disease from benign tumor.

OBJECTIVETo investigate the effect of water extracts of Coptidis Rhizoma and Evodiae Fructus (CREF) on the proliferation and apoptosis of human gastric carcinoma cells (SGC-7901) and determine the optimal proportion of Coptidis rhizoma to Evodiae fructus.
METHODSThe growth inhibition of SGC-7901 cells treated with the water extracts of CREF of varying proportions was tested with MTT assay. The cell apoptotic rate and mitochondrial membrane potential were analyzed with flow cytometry.
RESULTSThe water extract of CREF with Coptidis Rhizoma: Evodiae Fructus proportions at 1:6, 2:5, 3:4, 4:3, 5:2, and 6:1 all significantly inhibited the growth of SGC-7901 cells after a 24-h or 48-h treatment (P<0.05). The growth inhibition and cell death ratio both exhibited a dose-dependent pattern of Coptidis Rhizoma. Flow cytometry analysis showed that, after treatment of the cells with CREF at the proportions of 1:6, 2:5, 3:4, 4:3, 5:2, and 6:1, the apoptotic rate were (8.50 ∓ 1.59)%, (9.90 ∓ 1.01)%, (17.15∓1.68)%, (21.55 ∓ 1.97)%, (34.10 ∓ 1.06)% and (34.40 ∓ 1.02)%, respectively, all significantly higher than that in the control group [(1.69 ∓ 1.91)%, P<0.05]. JC-1 Kit staining showed that mitochondrial membrane potential of SGC-7901 cells was decreased and the ratio of green to red fluorescence increased significantly after incubation with CREF.
CONCLUSIONCREF can inhibit the growth and induce apoptosis of SGC-7901 cells, and the strongest effect is achieved at the optimal proportion of Coptidis Rhizoma and Evodiae Fructus at 6:1.
