Objective To investigate the prevalence of hypertension in patients with obstructive sleep apnea hypopnea syndrome (OSA) and the relationship between blood pressure (BP) with respiratory ventilation function. Methods Patients with OSA (n=3 607) were included in this study and divided into 4 groups based on their apnea-hypopnea index (AHI) scores:control group (control, n=354) with AHI<5;mild OSAHS (mild, n=658) with 5≤AHI<15;moderate OSAHS (moder?ate, n=753) with 15≤AHI<30;and severe OSA (severe, n=1 842) with AHI≥30. BP were measured at 4 time points (daytime, evening, midnight, and morning). The midnight/ daytime average BP (RN/D) and morning/evening average BP (RM/E) ratios were calculated. Finally, the general profiles, prevalence of hypertension and average BP of 4 time points were compared among 4 groups. The correlations of MBP with AHI and LSaO2 were also analyzed. Results The prevalence of hypertension as well as MBP at daytime and in the morning in the mild group (34.65%), moderate group (39.04%) and severe group (55.37%) were all higher than that in control group (22.32%)(all P<0.05). The prevalence of hypertension as well as MBP at daytime and in the morning were both higher in severe group than those in mild and moderate groups. MPB in the evening and at midnight was higher in severe group than that in moderate group than that in mild group than in control group (P<0.05). Average MBP of all four time points rise with increasing AHI (all P<0.05). The ratios of nighttime to daytime MBP (RN/D) and of morning to evening MBP (RM/E) increased with the severity of the illness (F=9.821, 18.957;P<0.001). The day? time BP correlated well with AHI and lowest oxygen saturation (LSaO2;systolic BP, r=0.195,-0.206;diastolic BP, r=0.248,-0.251, P<0.01). Daytime MBP increased gradually with increasing AHI until MPB reached 61-65, at which point it either plateaued or dropped slightly. Conclusion OSA patients have a significant increase in midnight and morning BP and lose normal BP nycterohemeral rhythm. OSA is an independent risk factor for hypertension.

ObjectiveTo observe the effect of occupational therapy (OT) on activities of daily living (ADL) of the children with cerebral palsy (CP).MethodsSixty-two CP children were treated with OT. The ADL scores of all children were assessed within one week after admission and training goal and plan were made according to evaluated result. The therapeutic effect was assessed before discharge.ResultsAfter OT treatment, the ADL scores of the children increased significantly ( P<0.01) and disable grades decreased (χ2=10.48, P< 0.01). The total effect rate was 87.1%.ConclusionOT training can improve ADL of the children with CP significantly.

Objective To explore the changes of serum nitric oxide(NO) and trace element Zinc in children with pneumonia and their clinical significance.Methods The observing group contained 48 patients with pneumonia in our hospital from Oct.2005 to May 2006,who were collected 3 mL of blood sample on empty stomach on the second day.Twenty-six of them had been collected serum during their convalescence stage.The control group contained 20 children,who were healthy in the same stage.The levels of NO of 48 pneumonia,26 convalescence stage(recovery group) and 20 healthy patients were determined by UV-2100 spectrophotometer.The Zinc in serum was determined by P-E503-mode atomic absorption spectrophotometric analysis antigenic in those patients.Blood viscosity was measured and analyzed with the statistic analysis SPSS 10.0 software.Results The levels of NO in pneumonia children[(57.76?19.41) ?mol/L] were significantly higher than that in control group [(25.09?5.51) ?mol/L] and recovery group[(30.08?8.05) ?mol/L](P_a

objective To investigate the ability of insulin sensitivity index HOMA2-%S and secretion function index HOMA2-%B calculated by HOMA2,the new homeostasis model assessment,in clinical application. Methods Eighty female volunteers with polycystic ovary syndrome in Chongqing area [50 subjects with normal glucose tolerance(NGT group)and 30 subjects with impaired glucose regulation(IGR group)]were involved in this study.Thev underwent a 75 g oral glucose tolerance test(OGTF)and the Botnia clamp test. From the data of faming blood samples in OGTF,insulin sensitivity index HOMAI-ISI,secretion function index HOMAl-β and disposal index DI-HOMA1 were calculated by the old homeostasis model assessment(HOMA I),meanwhile insulin sensitivity index HOMA2-%S,secretion function index HOMA2-%B and disposal index(DI-HOMA2) were caleulated by the new homeostasis model assessment (HOMA2).Correlation coefficients between insulin sensitivity index and GIR (the glucose infusion rate at steady state of Botnia clamp test),and between insulin secretion function index and AIR(the acute insulin response in Botnia clamp test),were studied.Results The Pearson's linear correlation coefficient between HOMA2-%S and GIR(r=0.503),HOMA1-ISI and HOMA2-%S (r= 0.990).HOMA2-%B and AIR(r=0.382),HOMA1-B and HOMA2-%B(r=0.976) were all statistically significant(a11 P<0.01).The glucose disposal indexes calculated from the HOMA2 and HOMA1 of 1GR group were significantly lower than those from the NGT group(t=2.825,P<0.Ol;t=2.222,P<0.05). Conclusion The HOMA2 is a better model in evaluating the insulin sensitivity and secretion function and is recommended to be widely used in clinical evaluation.

A mAb T2-2 was generated using hybridoma techniques, and its target was identified as a 46 ku-cytokeratin (CK), based on biochemical study and a completely overlapped binding pattern of mAb T2-2 with anti-pan-CKs antibodies. An epithelia-specificity of the mAb T2-2 was determined by screening 68 human normal and 65 tumor tissues using immunohistochemistry. Unlike most of anti-CKs antibodies, the mAb T2-2 recognized a mono-specific epitope only expressed on the 46 ku CK, suggesting that mAb T2-2 is superior to most anti-CKs antibodies that cross-reacted with many different kinds of CKs. In addition, it was found that the mAb T2-2 was multipurpose with a broad applicability to ELISA, immunohistochemistry, immunofluorescence, Western blotting, and was also compatible with various fixation reagents. These results strongly indicate that the mAb T2-2 has potential applications for studying CKs function and for diagnosis of tumor and other disorders.

Objective To study the role of OIf-1/EBF associated zinc finger protein (OAZ),a transcription factor encoded by a positional systemic lupus erythematosus (SLE) candidate gene,in the function of mesenchymal stem cells (MSC) of SLE patients by silencing this gene.Methods OAZ mRNA levels of bone marrow MSC obtained from 5 SLE patients and 5 healthy controls were detected by real-time PCR.Bone marrow MSC obtained from 6 SLE patients were incubated with specific siRNAs for 3 days,then cells were harvested for OAZ measurement,Idl-3 and CCL2 mRNA levels were tested by real-time PCR,and levels of CCL2 were detected in culture supernatants using ELISA.Differences between groups were analyzed using t-test or MannWhitney test.Results ① OAZ mRNA levels of bone marrow MSC were significantly elevated in SLE patients (0.013±0.016) compared to healthy controls (0.001±0.000,P=0.009).② After OAZ silencing,the expression levels of OAZ,Id1,Id2 and ld3 mRNA were significantly decreased (△Ct 10.3±0.7,15.2±1.6,8.1±1.4,10.5±0.6 vs 8.7±0.7,14.1±1.2,7.1±1.5,9.8±0.6) (P all ＜0.05).③ Both the expression levels of CCL2 mRNA (△Ct 2.2±1.1 vs 3.0±1.1 ) and the levels of CCL2 protein in culture supernatants [(341±29) pg/ml vs (304±19) pg/ml] were significantly increased in OAZ silencing group comparing to those in the control group (P all ＜0.05).Conclusion OAZ gene expression is significantly elevated in bone marrow MSC of SLE patients.OAZ may affect autoantibody production in SLE patients by regulating CCL2 expression.

objective To study the role of anti-EBV antibody in the development of systemic lupus erythematosus(SLE).Methods Peripheral blood was obtained from 55 SLE patients and 29 normal controls,and anti-EBV-VCA IgG,IgA,IgM antibody was detected by enzyme-linked immunosorbent assay[ELISA).Totat RNA was extracted from peripheral blood of 33 SLE patients and 26 normal controls and then reverse transcribed into complementary DNA.Real-time PCR technique was used to determine gene expressions at the transcription level.Comparison of anti-EBV antibody level and interferon inducible gene expression was made between SLE Datients and normal controls by t-test.The associations between anti-EBV antibody level,lupus activitv and IFN inducible gene expression were analyzed by Spearman's correlation analysis.Results (1)The levels of anti-EBV antibodies in SLE patients were significantly increased as compared to those in the normal controls[IgG(41±6)vs(19±6)U/ml,IgA(15.4±1.8)vs(8.3±2.1)U/ml,IgM(7.8±1.0)vs(3.7±1.2)U/ml]cantly elevated in SLE Datients as compared to normal controls[IFN scores 11±13 vs 0±3](all P<0.05),but not correlated with the levels of anti-EBV antibody in patients(all P>0.05).Conclusion Anti-EBV antibody is overproduced in SLE patients but not associated with disease activity as well as the expression level of several major types of I IFN inducible genes,suggesting that EBV infection may not be a major factor mediating the activation of IFN pathway and consequently the exacerbation of SLE.

Sleep is a common physiological phenomenon of animals.We may have different kinds of sleep disorders in our daily life,such as difficulty falling asleep,insomnia,hypersomnia and changes of sleep patterns,etc.Pain is a subjective response of the body to stimuli of certain degrees.Sleep disorders are closely related to pain:pain can interfere with people's normal physiology and psychology conditions and affect individual's sleep;different kinds of sleep disorders can affect the body' s sensitivity to pain.The relationship between pain and sleep disorders has become one of the most common causality in clinical research.In this paper we summarizes the pathophysiological relation and mutual influence between pain and sleep disorders.
