OBJECTIVE: To study the clinical value of polysomnography (PSG) and ApneaGraph (AG200) in the diagnosis evaluation of obstructive sleep apnea hypopnea syndrome (OSAHS). METHOD: From January to December in 2012, 67 OSAHS patients diagnosed by PSG were examined by AG200. The apnea hypopnea index (AHI), hypopnea index (HI), apnea index (AI), the lowest oxygen saturation (LSaO2) was were detected and the results were analyzed statistically. RESULT: Significant differences were observed in AI, AHI, LSaO2 between AG200 and PSG (P < 0.05, respectively). No statistically significant difference was found in HI. The differences in HI between AG200 and PSG were not significant (P > 0.05). AHI, HI and LSaO2 was were significantly correlated between AG200 and PSG (r = 0.870, 0.743, 0.374, 0.716, P < 0.01). CONCLUSION AG200 could not replace PSG but could identify the level of upper airway obstruction.

Objective To investigate the effect of diabetes on clinical efficacy of transcatheter arterial chemoembolization (TACE) in the treatment of non-viral hepatitis hepatocellular carcinoma (HCC). Methods Retrospectively analyzed the clinical data of 367 non-hepatitis virus HCC patients treated by TACE, included 153 diabetes mellitus cases (test group) and blood glucose of 214 patients was normal (control group). To assess the treatment effect after 1 month of TACE based on response evaluation criteria in solid tumors, include complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), and calculate the disease control rate. Through 6 to 75 months follow-up to observed long-term efficacy, record the time to progression (TTP) and overall survival (OS) time. Survival rate were analyzed using Kaplan-Meier method and Log-rank analysis by SPSS 16.0. The single-factor analysis was used to analyze variables which variables that differed were analyzed by Cox regression. Results The disease control rate of test group was 69.9%(107/153) and control group was 74.3%(159/214), the difference was no statistically significant (P=0.125). The median time to progression (mTTP) and median overall survival (mOS) of test group were 10.0 and 15.0 months;and the mTTP and mOS of control group were 14.0 and 19.0 months, the difference were statistically significant (P=0.023 and P= 0.026). Tumor diameter ≥4.5 cm, numbers of tumor ≥3, invasion of blood vessels, α-fetoprotein≥200 μg/L, Eastern Cooperative Oncology Group score and diabetes were risk factors for OS of HCC patients. Conclusion Diabetes is unfavorable factors for overall survival of non-hepatitis HCC tread by TACE.

A UPLC-MS/MS method based on metabonomic skills was developed to study the serum metabolic changes of rats after acute liver injury induced by CCl4 and to evaluate the action mechanism of Si-Ni-San. The integrated data were exported for principal components analysis (PCA) by using SIMCA-P software, in order to find the potential biomarkers. It showed that clear separation of healthy control group, model group, silymarin group, Si-Ni-San group was achieved by using the PCA method. Nine significantly changed metabolites were identified as potential biomarkers of acute liver injury. Compared with the health control group, the model group rats showed higher levels of phenylalanine, tryptophan and GCDCA together with lower levels of LPC 16 : 0, LPC 18 : 0, LPC 18 : 1, LPC 16 : 1, LPC 20 : 4 and LPC 22 : 6. These changes of serum metabolites suggested that the disorders of amino acid metabolism, lipid metabolism, bile acid biosynthesis and anti-oxidative damage were related to acute liver injury induced by CCl4. Si-Ni-San might have the anti-liver injury effect on all these four metabolic pathways.

Objective To investigate the prevalence of and risk factors for glucocorticoid-induced diabetes mellitus (GDM) in patients with pemphigus or pemphigoid receiving glucocorticoid therapy.Methods This study included 68 hospitalized patients with pemphigus or pemphigoid receiving glucocorticoid therapy in the Institute of Dermatology,Chinese Academy of Medical Sciences and Peking Union Medical College from December 2011 to January 2013.Comparisons were carried out between patients with GDM and those without regarding multiple parameters,including age,sex,body mass index (BMI),pathological type,initial dose and maximum daily dose of glucocorticoids,family history of diabetes mellitus,immunosuppressive treatment,etc.Independent samples t test was used for intergroup comparisons,Chi-square test and Fisher exact probability test for the analysis of count data,and a logistic regression model for the determination of risk factors.Results Among the 68 patients,26 (38.2％) developed GDM during glucocorticoid therapy.Univariate logistic regression analysis showed that the initial dose of glucocorticoids (P ＜ 0.05,OR 1.023,95％ CI 1.002-1.044),maximum daily dose of glucocorticoids(P ＜ 0.01,OR 1.037,95％ CI 1.013-1.062),duration of glucocorticoid treatment (P ＜ 0.05,OR 1.143,95％ CI 1.028-1.271),BMI (P ＜ 0.01,OR 1.265,95％ CI 1.080-1.481) and dexamethasone use (P ＜ 0.01,OR 6.0,95％ CI 1.887-19.076) were risk factors for GDM in these patients.Multivariate logistic regression analysis showed that BMI (P ＜ 0.05,OR 1.223,95％ CI 1.017-1.471) and maximum daily dose of glucocorticoids (P ＜ 0.05,OR 1.037,95％ CI 1.009-1.065) were independent risk factors for GDM.Conclusions In this study,38.2％ of the patients with pemphigus or pemphigoid developed GDM during glucocorticoid therapy.BMI and maximum daily dose of glucocorticoids seem to be independent risk factors for GDM.

Objective To investigate the effective ways of improving medical students' clinical competence during the process of internship. Methods Totally 398 students of clinical medicine from 2006 and 2007 grade in Soochow University were enrolled as research objects. Forty objects distribut-ed to the First Affiliated Hospital were taken as experiment group while 358 objects distributed to other hospital as control group. In experiment group, objective structured clinical examination (OSCE) was introduced during regular internship, innovation was made on test on completion of a course and autonomous learning and clinical practice was advocated and enhanced. Traditional practice and ex-amination method was used in control group. SPSS 19.0 was used to do statistical analysis on the test scores of students. Paired sample t test and independent sample t test were employed. Measurement data is expressed as x±s and P<0.05 signifies statistically significant differences. Results Clinical practice ability of students in experiment group was enhanced to various degrees after internship com-pared with that before internship. ECG interpretation, heart and lung auscultation, interrogation tech-nique, medical and surgical operation performances of students in experiment group were promoted significantly (P<0.05). Students' overall competence in the final graduation skill test was better in ex-periment group than in control group (P<0.05). Conclusions OSCE-test on completion of a course not only make intern management more effective, but also make students' aim more definite, therefore it is conducive to enhancing clinical competence.

OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).

METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.

RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.

CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.
