Objective To explore the predictive value of cholinesterase (ChE) in the prognosis of gerontal patients with systemic inflammatory response syndrome. Methods The clinical data of 124 elderly patients with systemic inflammatory response syndrome collected from September 2009 through September 2010 were retrospectively analyzed. All patients were divided into death group and survival group according to the outcome of patients. The cholinesterase ( ChE), albumin, D-Dime, lactic acid and C-reactive protein (CRP) were detected, and the APACHE Ⅱ and GCS scores were documented in the first 24 hours in the ICU. Results There were no significant differences in age, gender, APACHE Ⅱ score and GCS score of patients between death group and survival group ( all P ＞ 0. 05 ), but there were significant differences in lactic acid, D-Dime, albumin, CRP and ChE between two groups ( theP values were 0.011,0.011, 0. 007,0. 008, 0. 000, respectively) . The results of multiple factors regression analysis showed that age, gender,lactic acid, D-Dime, albumin, CRP, APACHE Ⅱ score, and GCS score were not the independent risk factors of prognosis of gerontal patients with SIRS ( the P = 0. 401, 0. 165, 0. 446, 0. 841,0. 615, 0. 120,0. 502, 0. 184, respectively) except ChE ( P = 0. 000) . The receiver operating characteristic curve (ROC) of ChE in the gerontal patients with SIRS showed the area under curve (AUC) = 0.797, SE =0.04, P=0. 000, and the ChE = 103.00 U/L could be a diagnosis point with sensitivity = 0.793, 1-specificity = 0. 258. The correlation analysis showed that the APACHE Ⅱ score, CRP, and albumin were poorly correlated with ChE ( Kendall coefficients were 0. 061, 0. 231, and -0. 090, and theP = 0. 161,0. 000, and 0. 069, respectively ) . Conclusions ChE maybe played a important role in the gerontal patients with SIRS, and could be a predictive index for the prognosis of gerontal patients with systemic inflammatory response syndrome.

ObjectiveTo investigate the value of urinary BNP for diagnosis of chronic heart failure (CHF). MethodsThe levels of Urinary BNP and plasma BNP were measured by microparticle enzyme immunoassay (MEIA) in 83 patients with CHF and 30 control subjects. The heart function was classified according totheNYHAcriteria. Leftventricularejectionfractions(LVEF)weremeasuredby echocardiology. ResultsThe level of urinary BNP in patients with CHF was[90. 0(38. 3 -209. 5 )]ng/L and the level of plasma BNP was[680. 0 ( 289. 7 - 1543.5)]ng/L, both of them were much higher than those in healthy subjects,[17. 0 ( 13.0 - 33. 0)]ng/L and[84. 5 ( 56. 0 - 158.0 )]ng/L, respectively (P＜0. 01 ). The concentrations of urinary BNP increased gradually with more severe symptoms ( NYHA cl ass Ⅰ -ⅣV ). The level of urinary BNP was positively correlated with NYHA class ( r = 0. 742, P ＜ 0. 01 )and the level of plasma BNP (r =0. 842,P ＜0. 01 ) while negatively related with LVEF (r = -0. 801 ,P ＜0. 01 ). The level of urinary BNP in patients with LVEF ＜ 40％ was[143.0 ( 85. 0 - 258.0)]ng/L , which was much higher than that in patients with LVEF≥40％ ,[31.5( 17.3 -38. 8)]ng/L, (P ＜0. 01 ). At a decision threshold of 36. 5 ng/L, the urine BNP assay demonstrated a clinical sensitivity and specificity of 84％ and 80％ ,respectively. In this study,the area under the curve(AUC) was 0. 905. ConclusionUrinary BNP is a new candidate marker for the diagnosis of CHF,it provides a similar accuracy with plasma BNP.

OBJECTIVE: To investigate the effects of Naohuandan Recipe on learning and memory abilities of SAM-P/8 mice and its role in anti-oxidation and anti-apoptosis. METHODS: Forty SAM-P/8 mice were randomly divided into four groups, which were untreated (normal saline-treated) group, Yinkeluo Tablets (extracts of gingko leaf)-treated group, low-dose Naohuandan Recipe-treated group and high-dose Naohuandan Recipe-treated group. Mice in these groups were given corresponding drugs orally for 105 days. Then the performances of learning and memory of mice were tested by a step-down passive avoidance task and a Y-maze test. The serum levels of superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) were detected. The expression level of bcl-xl mRNA in cerebral cortex and hippocampus of mice was detected by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The performances of learning and memory in the Yinkeluo Tablets-treated group, low- and high-dose Naohuandan Recipe-treated groups were significantly improved as compared with those in the untreated group (P<0.05 or P<0.01), and such performance was the best in the high-dose Naohuandan Recipe-treated group among these four groups (P<0.01). The serum levels of SOD and GSH-Px and the expression of bcl-xl mRNA in cerebral cortex and hippocampus of mice in the Yinkeluo Tablets-treated group, low- and high-dose Naohuandan Recipe-treated groups were also significantly higher than those in the untreated group (P<0.05 or P<0.01), while the serum level of MDA in the untreated group was higher than that in the other three groups (P<0.01). CONCLUSION: Naohuandan Recipe can improve learning and memory abilities of SAM-P/8 mice, and this effect may be related to its anti-oxidation efficacy and enhancement of expression level of bcl-xl mRNA.

ObjectiveTo explore the relationship between sleep quality and glucose level,diabetic complications in elderly type 2 diabetes mellitus.Methods A total of 130 hospitalized elderly type 2 diabetes in our hospital were included in the study. Questionnaires and other related clinical data were collected within one week after admission.Patients were divided into two groups:poor-sleeper group and good-sleeper group according to Pittsburgh Sleep Quality Index(PSQI).ResultsSixty percent (78/130) of these patients were poor sleepers. The following parameters differed in the two groups:the duration of diabetes [ (7.9 ± 1.8 ) years vs ( 7.2 ± 1.5 ) years,t =2.318 ],systolic blood pressure [ ( 148 ± 30 ) mm Hg ( 1 mm Hg =0.133 kPa) vs ( 138 ± 23 ) mm Hg,t =2.037 ],fasting plasma glucose (FPG) [ ( 10.7 ± 2.2) mmol/Lvs ( 9.8±1.9)mmol/L,t =2.410],hemoglobin A1c (HbA1c) [(8.6 ±2.2)％ vs (7.8±2.1 ) ％,t =2.068],high-sensitive C-reactive protein (hs-CRP) [ (5.27 ± 2.34) mg/L vs (4.44 ± 1.76)mg/L,t =2.179 ],ratio of diabetic complications ( 61％ vs 32％,x2 ＝ 4.257 ),percentage of depression ( 20％ vs 8％,x2 =3.722 ),score of life quality [ ( 98 ± 19 ) scores vs ( 89 ± 13 ) scores,t ＝ 2.980 ],and proportion of patients treated with insulin (32％ vs 12％,x2 =4.489). All the above parameters were significantly higher in poor-sleeper group than the good-sleeper group (all P value＜ 0.05 ). Multiple correlation analysis showed that the factors affecting sleep quality were FPG,HbA1c,duration of diabetes,diabetic complications,depression,life quality and insulin application (r =0.213,0.257,0.223,0.335,0.422,0.3451,0.231,respectively ; all P value ＜ 0.05 ).By multivariate logistic regression analysis,the followings were found:FPG (β =1.29,P ＜ 0.05 ) and PSQI (β =1.07,P ＜ 0.05 ) were found to be correlated with HbA1c.With increasing of PSQI,FPG,HbA1c,diabetic complications and life quality were changed significantly( all P value ＜ 0.05 ).The indcpcndcnt risk factors of diabetic complications were duration of diabetes ( OR ＝ 1.32,95％ CI 1.01-2.01 ),HbA1c ( OR =2.01,95％ CI 1.63-2.67 ),hs-CRP( OR =1.12,95％ CI 1.08-1.21 ) and PSQI ( OR =1.71,95％ CI 1.58-2.02).ConclusionsElderly type 2 diabetes mellitus are usually poor sleepers. Sleep quality probably affects blood glucoseregulation, and is closely correlated with the occurrence of complications.In addition,poor sleep quality results in poor life quality.
