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.

Objective To explore the regulatory effect of astragalus polysaccharide ( APS) on immune function in immunosuppressed mice, and to establish a set of feasible indexes of immunological regulation and evaluation system of pol-ysaccharides.Methods Both Cytoxan ( CTX)-induced immunosuppressed mice and normal mice were treated with astrag-alus polysaccharide ( APS) .Spleen index, thymus index, phagocytosis rate and phagocytic index of peritoneal macrophages were assessed, and the spleen and thymus tissues were examined by histology.The percentage of CD3 +, CD4 +, and CD8 +cells in peripheral blood were determined by flow cytometry.Results APS significantly increased the thymus and spleen indexes in both immunosuppressed mice and normal mice, promoted the histological development of spleen and thy-mus in normal mice, enhanced the recovery of histological structures in the spleen and thymus in the CTX-induced immuno-suppressed mice.APS also enhanced the phagocytosis rate and phagocytic index of peritoneal macrophages in both immuno-suppressed mice and normal mice.In addition, the percentage of CD3 +and CD4 +cells,the ratio of CD4 +/CD8 +in pe-ripheral blood of both CTX-induced immunosuppressed mice and normal mice were increased while CD8 +cells were de-creased.Conclusions The results of this study suggest that astragalus polysaccharide can improve the non-specific immu-nity and cellular immunity in mice, and indicate that we established comprehensive evaluation indexes of immunoregulatory effects of polysaccharides.

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.

The superior cervical ganglia (SCG) were dissected from neonatal rats.Dissoci-ated cell cultures were grown in Eagle's MEM supplemented with 20% calf serumwhich contain nerve growth factor (NGF).The cultures were divided into two groups:laser irradiation group and control.The former was exposed to lower dose of Helium-Neon laser (power:4 milliwatt)5 minutes every two hours.Two groups cultured for 20,22,24 and 28 hoursrespectively.Then the length of neurites of neurons were measured.At 22 hours,RNA and DNA synthesis of neurons labeled by ~3H-uridine and ~3H-thymidine wereobserved.The results showed that lower dose of Helium-Neon laser irradiation not onlypromotes growth of neurite but also enhances RNA synthesis of neurons in culture.However DNA synthesis in neurons does not promote in this experiment.
