Objective To investigate the prevalence of excessive daytime sleepiness and explore the associated factors in university teachers and staffs in Kunming.Methods Epworth sleepiness scale was used as the tool of diagnosis. We consecutively collected the data of teachers and staffs on duty in Yunnan Nationalities University,Yunnan Agricultural University,Yunnan Normal University,Kunming Medical University and Yunnan University of Finance and Economics within 8 months.Results The prevalence of excessive daytime sleepiness in university teachers and staffs was 12.45%, the prevalence of male was 16.82% and female was 7.70%, respectively. The results of Logistic regression showed that the main associated factors of excessive daytime sleepiness were male (OR=1.898),age (30 years and less was as control group,the ORs of 31-40 year group, 41-50 years group and more than 51 years group were 1.480, 2.366 and 2.719, respectively), family history of snoring (OR=3.371), consumption sedative (OR=1.815), memory failing (OR=2.044), dizzy and feeble (OR=2. 076),choking (OR=2.143),report apnea (OR=2.684),etc. Conclusions The prevalence of excessive daytime sleepiness is high in the university teachers and staffs that can partially represent the residents of Kunming city. The associated factors of excessive daytime sleepiness hint that excessive daytime sleepiness may be caused by sleep apnea/hyperpnoea syndrome in the sample population,hence the people with excessive sleepiness need further sleep monitoring .

Objective To evaluate the prognostic value of iASPP for nasopharyngeal carcinoma (NPC).Methods One hundred and thirty patients with nasopharyngeal carcinoma were initially diagnosed and treated between January and December 2012 in Department of Radiation Oncology of the First Affiliated Hospital of Guangxi Medical University.The clinical staging was classified according to the cancer staging criteria 2009 AJCC/UICC.All patients were treated by IMRT.Cisplatin-based concurrent chemotherapy was given to patients with stages Ⅲ-ⅣB disease.Immunohistochemistry was used to detect the expression of iASPP in the carcinoma tissues,and the clinicopathological features were compared among the patients with different expressions of iASPP.Furthermore,the relationship between the expression of iASPP and the efficacy in patients was explored.Results Of 130 patients,positive expression of iASPP was observed in 86 patients (66.2％),and negative expression in 44 patients (33.8％).There was significant difference in the positive expression rate of iASPP among the patients with different N-stage and clinical stages(x2 =7.565,4.947,P ＜ 0.01).At three months after treatment,no significant difference was found in the response rate of tumor with different expression of iASPP.In univariate analysis,the expression of iASPP was significant predictor of 3 year-DMFS (x2 =4.335,P =0.037) and PFS (x2 =6.640,P =0.01).Furthermore,N-stage was significant predictor of 3y-DMFS (x2 =8.058,P =0.005),PFS (x2 =9.554,P =0.002) and OS (x2 =6.987,P =0.008),respectively.By using multivariate Cox analysis,the expression of iASPP and N-stage was independent prognostic factors for PFS (x2 =4.336,5.228,P ＜ 0.05),respectively.Conclusions Positive expression of iASPP may be a poor prognostic factor for NPC patients.

Purpose:The efficacy of evaluation of changes of tumoral uptake of 3'-deoxy-3'-[~(18)F] fluorothymidine (FLT) was comparatively analyzed with that of ~(18)F-FDG at early stage after anticancer chemotherapy.Materials and Methods:Cells derived from human lung adenocarcinoma were incubated with cisplatin (CDDP),5-fluorouracil(5-FU),doxorubicin (Dox),for 1,4,24 and 72h.The doses(CD-DP: 67 μM; 5-FU 1,540 μM;MTX: 440 μM;) were determined corresponding to a estimated 10% - 95% proliferation inhibition.The cells were allowed to recover before FLT or FDG being added into the culture media for 60 min.Cell counts,viability,estimated by MTT method,were used to evaluate the cytotoxic effects of chemotherapy.Results: FLT uptake was increased significantly at 1 and 4 h after treatment with 5-FU( 145 ± 12%,150 ± 14%,P <0.01).decreased at 24 h and 72 h.In contrast,FLT accumulation was significantly reduced at cytostatic concentrations of CDDP at different time.The uptake of FDG did not change significantly at early time points after treatment,but decreased at 72 h.Conclusion: The tumor cell uptake of FLT revealed specific changes depending on the auti-cancer drug used at much earlier time than FDG after chemotherpay.

Objective To evaluate the short-term therapeutic effects of DNA immunoadsorbent (IA) combined with glucocorticoid and immune depressant on patients with severe systemic lupus erythematosus(SLE). Methods 32 patients with severe SLE were selected to undergo DNA IA treatment combined with glucocorticoid plus cyclophosphamide therapy, and each patient received IA therapy 3 times, once 2.5 hours, with an interval of 24-48 hours to take another two times of IA. The changes in SLE disease activity index(SLEDAI)score, health status evaluation indexes〔 physiologic functional( PF) and emotional health( MH) scores〕,renal function indexes〔 blood urea nitrogen(BUN)and serum creatinine(SCr)〕 were observed; and anti-double stranded DNA antibody( ds-DNA), immunoglobulin (IgA, IgG, IgM), complements(C3 and C4)and high-sensitivity C-reactive protein (hs-CRP) were examined before and after IA treatment for 2 weeks. Results Two weeks after the combination therapy, the SLEDAI score, BUN, SCr, dsDNA, IgA, IgG, IgM, hs-CRP were significantly lower than those before treatment 〔SLEDAI score : 14.38±3.85 vs. 15.69±1.40, BUN (mmol/L): 11.22±4.78 vs. 16.31±7.90, SCr (μmol/L): 127.02±38.17 vs. 167.25±45.63, dsDNA( U/L): 1.36±0.12 vs. 1.43±0.18, IgA( g/L): 2.41±0.73 vs. 2.59±0.86, IgG( g/L): 16.82±4.83 vs. 21.01±4.84, IgM( g/L): 1.64±0.45 vs. 1.75±0.58, hs-CRP( mg/L): 14.41±2.20 vs. 14.94±2.60, P<0.05 or P<0.01〕; PF score, MH score, complement C3 were increased〔 PF score : 71.19±17.53 vs. 56.66±22.41, MH score : 74.01±15.72 vs. 61.50±17.98, C3( g/L): 0.56±0.09 vs. 0.52±0.10, all P<0.05〕; clinical symptoms were improved significantly, and no significant adverse reactions were found. Conclusion IA combined with medical treatment has shown that it has significant therapeutic effect for treatment of patients with severe SLE, and it may decrease the levels of dsDNA, IgA, IgG, IgM,hs-CRP, and increase the level of complement C3.

Accurate judgment of conditions and prognosis has important clinical significance in improving survival rate and optimal distribution of liver source in patients with liver failure. This article reviews the current application of prognostic markers for liver failure such as alanine aminotransferase, aspartate aminotransferase, total bilirubin, prothrombin time, prothrombin time activity, and international normalized ratio and summarizes the new markers discovered in recent years, such as inflammatory response-related markers, neutrophil gelatinase-associated lipocalin, immune response-related markers, keratin, intestinal flora, microRNAs, liver failure autoantigen and autoantibody, and hemodynamic disorder. It is pointed out that the prognosis of liver failure is affected by many factors and there is still a lack of more sensitive and effective markers and a standardized prognostic scoring system. The new markers used alone or in combination with traditional markers may help to improve the sensitivity and specificity of prognostic evaluation of liver failure.

OBJECTIVE: To determine the effect of lung protection mechanical ventilation on respiratory function in the elderly undergoing spinal fusion. METHODS: Sixty 70-85 year old patients, ASA class II or III, undergoing spinal fusion were randomly assigned into 2 groups (30 in each group): a protection mechanical ventilation group (group P) and a conventional mechanical ventilation group (group C). Low VT and low level positive end expiratory pressure (PEEP) mechanical ventilation were applied in group P (VT=6mL/kg, RR=12-18 b/min, I:E=1:2, PEEP=10 cmH2O, alveolar recruitment performed once every 15 min), while traditional ventilation was used in group C ( VT=10-12 mL/kg, RR=12 b/min, I:E=1:2). Arterial blood samples were taken and pH, PaO2, PaCO2, PaO2/FiO2, A-aDO2, HR, SBP, DBP and CVP were recorded before the operation (T0), 1 h after tracheal intubation (T1), tracheal extubation immediately (T2), 1 h after tracheal extubation (T3), 1 d, 2 d, and 3 d after the operation (T4, T5, and T6). The pulmonary complication was also examined 1 d after the operation. RESULTS: At T1, T2, T3, T4 and T5, PaO2 and PaO2/FiO2 in group P were higher than those in group C, but A-aDO2 in group P was lower than that in group C. Five patients had bronchitis, 5 had hyoxemia, and 3 had atelectasis in group C, but 2 bronchitis in group P. The incidence of pulmonary complication was 43.3% in group C and 6.6% in group P. There was no significant difference in HR, SBP, DBP and CVP between the 2 groups. CONCLUSION Lung protection mechanical ventilation improves the arterial oxygenation and accelerates the recovery of respiratory functions in elderly patients after spinal fusion operation, with no influence on hemodynamics.

Background/Aims: To investigate the autoantibody against fumarate hydratase (FH), which is a specific liver failure-associated antigen (LFAA) and determine whether it can be used as a biomarker to evaluate the prognosis of acute-on-chronic liver failure (ACLF). Methods: An immunoproteomic approach was applied to screen specific LFAAs related to differential prognosis of ACLF (n=60). Enzyme-linked immunosorbent assay (ELISA) technology was employed for the validation of the frequency and titer of autoantibodies against FH in ACLF patients with different prognoses (n=82). Moreover, we clarified the expression of autoantibodies against FH in patients with chronic hepatitis B (n=60) and hepatitis B virus-related liver cirrhosis (n=60). The dynamic changes in the titers of autoantibodies against FH were analyzed by sample collection at multiple time points during the clinical course of eight ACLF patients with different prognoses. Results: Ultimately, 15 LFAAs were screened and identified by the immunoproteomic approach.Based on ELISA-based verification, anti-FH/Fumarate hydratase protein autoantibody was chosen to verify its expression in ACLF patients. ACLF patients had a much higher anti-FH autoantibody frequency (76.8%) than patients with liver cirrhosis (10%, p=0.000), patients with chronic hepatitis B (6.7%, p=0.022), and normal humans (0%, p=0.000). More importantly, the frequency and titer of anti-FH protein autoantibodies in the serum of ACLF patients with a good prognosis were much higher than that of patients with a poor prognosis (83.9% vs 61.5%, p=0.019; 1.41±0.85 vs 0.94±0.56, p=0.017, respectively). The titer of anti-FH autoantibodies showed dynamic changes in the clinical course of ACLF. Conclusions The anti-FH autoantibody in serum may be a potential biomarker for predicting the prognosis of ACLF.
