[ABSTRACT]OBJECTIVETo assess the upper airway and related structures in different patterns of the upper airway obstruction on cine magnetic resonance (CMR) imaging in patients with obstructive sleep apnea hypopnea syndrome (OSAHS).METHODSCMR images of upper airway were obtained in 30 male patients with severe OSAHS during waking state and natural sleep. The midsagittal plane images were obtained. Patients were classified into 3 groups based on the upper airway obstruction patterns at apnea events and the reference data of the upper airway were measured.RESULTSDuring natural sleep, the diameter of retropalatal region, retroglossal region, retroepiglottic region and the length of suprahyoid muscles were significantly shorter than those during waking state (P<0.01). The maximum angle between the suprahyoid muscles and the apex of the tongue during natural sleep was significantly larger than that during waking state (P<0.01). During wakefulness, there was a significantly difference in the diameter of retropalatal region among 3 obstruction patterns (P<0.01). During natural sleep, there were statistical difference in the diameter of retropalatal region and the upper tongue, the angle between the hard palate and soft palate, the maximum angle between the suprahyoid muscles and the apex of the tongue, and their change values among 3 obstruction patterns (P<0.05). CONCLUSIONThe measurements of the upper airway and related structures on CMR imaging in OSAHS patients could provide useful information in assessing upper airway.

Objective To study the genotyping of clarithromycin-resistant Helicobacter pylori(Hp) isolates.Methods From March 2007 to October 2007,247 gastric mucosa specimens were collected by the endoscopy from the patients with peptic ulcer or gastritis at the affiliated hospital of Youjiang Medical College for Nationalities.A total of 126 Hp strains were isolated.Resistance to clarithromycin in Hp was determined by E-test.All of the resistant isolates were genotyped with REP-PCR and further clustered with NTsys_2 software.The clinical data was collected for these patients with clarithromycin-resistant Hp.Results The 26 clarithromycin-resistant isolates from the west of Guangxi were divided into six genotypea including Group Ⅰ,Group Ⅱ,Group Ⅲ,Group Ⅲ,Group Ⅳ,Group Ⅴ and Group Ⅵ according to the homology of 78%.Every group have 2,11,1,8,3,1 strains Hp,respectively.Strains of group Ⅱ were isolated from patients with peptic ulcer and most of them from Chuang patients.All strains of group Ⅳ were isolated from patients with gastritis.Conclusions The clarithromycin-resistant isolates were divided into six groups by REP-PCR Disease type.nationality of patients and family history of stomach diseases were associated with the genotypes.

OBJECTIVE To recognize the frontal recess cells and analyze their distributional characteristics during image navigation assisted endoscopic sinus surgery. METHODS 20 cases(39 sides)of chronic sinusitis with nasal polyps were observed in this study. The fontal recess cells and frontal sinus were opened under the endoscope and the distributional characteristics were observed and recorded, and then confirmed by the image navigation system. RESULTS Centred on frontal sinus ostium, frontal recess cells were divided into three areas: the agger nasi cell(ANC)and frontal cells(FC)are located in front of frontal sinus ostium(FS); frontal septum cells(IFSSC)and terminal cells(RT)are located at the same plane of FS; supra-ethmoidal bulla recess(SBR), frontal bulla cell(FBC)and super-obital cells(SOEC)are in the posterior area. The coincidence of identification for ANC, FCI and II, SBR, FBC and IFSSC under endoscope and image navigation is 100%, the coincidence of identification for FS is 89.7%, SOEC 80%, RT 71.4% and FC III and IV 60%. CONCLUSION The distribution of the frontal recess cells around the frontal ostium showed a fixed pattern.It would well benefit the orientation of frontal ostium and the opening of frontal sinus. Furthermore, it is significant for the orientation and opening of the frontal recess cells.

Objective To study the value of magnetic resonance vessel wall imaging in assessing the atherosclerotic plaque burden of rabbit model.Methods We built up abdominal atherosclerotic animal model in 30 New Zealand rabbits by high lipid diet combined with abdominal artery denudation.The animals were divided into 3 groups randomly,which were the 1-week group,1-month group and 2-months group.The MRI and histology examination were carried out at relative time points.The correlations of area or thickness of vessel wall by MRI with histology examination were analyzed.Results Among the 30 rabbits,3 died due to anesthesia or surgery,one rabbit model failed because of the thin vessel,and another 3 died of diarrhea or inflammation during the high lipid diet feeding.Eventually,totally 23 rabbits fulfilled the examinations (7 in 1-week group,7 in 1-month group and 9 in 2-months group).The vessel wall area of histology examination grew larger along with the post-surgery duration,from 1.7663 mm2of 1-week group to 2.4371 mm2 of the 1-month group till 3.5978 mm2 of 2-months group,with statistic significant difference among 3 groups (F=5.052,P=0.017).There were strong correlations of area or thickness vessel wall resulted from MRI with histology examination(r=0.688,0.642;P=0.001,0.002).Conclusions High resolution MR vessel wall imaging technique may evaluate and follow up the plaque burden in the early stage of atherosclerosis.

Objective To evaluate the clinical significance of bone marrow minimal residual disease (MRD) monitoring by multi-parameter flow cytometry (FCM) regularly after the first complete remission (CR1) in patients with acute myeloid leukemia (AML).Methods A total of 63 paitents with AML who had got CR1 after chemotherapy were regularly monitored for MRD in bone marrow by FCM,and MRD ≥ 10-4 was positive.According to the latest standards of National Comprehensive Cancer Network (NCCN) for disease risks,they were categorized into three groups:better risk group (20 cases),intermediate risk group (27 cases) and poor risk group (16 cases).The probability of continuous complete remission (CCR) was calculated by KaplanMeier formula,and the statistical difference between MRD positivc and MRD negative CCR probabilities was evaluated by log-rank test.Results The positive rates of MRD were 20％(4/20),30％(8/27) and 10/16 in better risk group,intermediate risk group and poor risk group respectively.The difference between better risk group and intermediate risk group had no statistical significance (P=0.454),and the difference between poor risk group and intermediate risk group had statistical significance (P =0.035).Twenty-two cases showed positive MRD,and 41 cases showed negative MRD.The probability of CCR at 24 and 36 months in MRD positive patients were 18％ (4/22),18％ (4/22),in MRD negative patients were 83％ (34/41),80％ (33/41),and there were significant differences (P ＜ 0.01).Conclusions The dynamic detection of MRD by FCM can be used to evaluate the therapeutic effect and prognosis of AML.MRD monitoring has important clinical significance and can help to adjust the intensity of chemotherapy,carry out individualized treatment,predict prognosis,and choose appropriate therapy.

Objective To study the risk factors of mortality in severe sepsis and septic shock patients. Methods 142 patients with severe sepsis and septic shock in ICU were observed and divided into alive group (98 patients)and dead group (44 patients)by using hospital mortality.The risk factors of mortality in severe sepsis and septic shock patients were assessed by binary logistic regression.Results Independent mortality risk factors were inotropic agents (OR =4.329,95%CI:1.045 -17.937,P =0.043),blood glucose >10 mmol/L (OR =3.771,95%CI:1.214 -11.710,P =0.022)and APACHE Ⅱ score (OR =3.098,95%CI:2.012 -4.760,P =0.000),while PaO2 /FiO2 after early goal -directed therapy (EGDT)was protective factor (OR =0.682,95%CI:0.500 -0.930, P =0.016).Conclusion Severe sepsis and septic shock patients with inotropic agents,blood glucose >10mmol/L, high APACHE Ⅱ score and decreased PaO2 /FiO2 after EGDT indicate poorly prognosis.

OBJECTIVETo investigate the mortality rates of hepatocellular carcinoma (HCC) in Nantong,China from 1999 to 2011, in order to uncover dynamic trends and provide reasoned advice on intervention strategies to decrease HCC incidence and mortality in Nantong in the future.

METHODSVersions 10 and 9 of the WHO International Classification of Diseases (ICD-10 and ICD-9) were used to determine the number of HCC deaths in Nantong,China for the study's range of years. Thex2 test was applied to compare the HCC mortality rates according to sex and age. The Grey system GM(1,1) model was used to predict the next-5-year HCC mortality for Nantong.

RESULTSAnalysis of the standardized mortality in Nantong showed a slight decreasing trend from 1999 to 2011 (x2=57 545.98, P less than 0.001),with males showing a steeper decrease than females. The total mortality of HCC during these years was 53.41 per 100,000 people,with mortality among males being significantly higher than that among females (80.81 per 100,000 people vs. 26.94 per 100,000 people; x2=13 625.42, P less than 0.001). In general, HCC mortality increased with increase in age (general trend:x2=57 545.98, P less than 0.001; male trend: x2=39 878.8, P less than 0.001; female trend: x2=20 105.3, P less than 0.001). However,HCC mortality increased significantly in women after the age of 40 and in men after the age of 35. The GM(1,1) equation was: Yt=-1265.28e(-0.0375t)+1315.5, which predicted that the HCC mortality will decrease to 25.56 per 100,000 people in 2016.

CONCLUSIONAlthough HCC mortality generally decreased from 1999 to 2011, the rate remained high. Public health intervention strategies may be more effective if they focus on males over the age of 35 and females over the age of 40.
