ObjectiveTo assess the degree of pain in elderly patients with mechanical ventilation in ICU using critical-care pain observation tool(CPOT) and to choose the correct sedative and analgesic method.Methods 110 elderly patients in ICU after neurosurgery were divided into three assessment stages,every stage had two record points and total six points (T1-T6):the first stage (intubation and unconsciousness,T1-T2),the second stage (intubation and consciousness,T3T4 ) and the third stage(extubation and consciousness,T5-T6 ).Among them T1,T3and T5were nonnocuity assessment points of every stage,while T2,T4 and T6 were nocuity assessment points of every stage.The assessment time was one minute at every point.After recorded at every point in second and third stages,patients were asked to use the pain intensity descriptive scale (PIDS) themselves.CPOT,heart rate and mean arterial pressure (MAP) from T1 to T6 were recorded as well as PIDS from T3 to T6 in second and third stages.Results In the three stages,CPOT〔(26.8 vs.0.54,3.36 vs.1.20,2.78 vs.0.68) scores〕,HR〔(95 vs.85,94 vs.82,94 vs.84)beat/min〕 and MAP〔(95 vs.85,95 vs.87,94 vs.87)mm Hg〕 at T2,T4and T6 were higher than T1 (t=-42.89,-55.95,-55.38),T3 (t =- 5.52,- 11.33,- 11.78) and T5 ( t =- 5.54,- 9.95,- 11.33 ) ( P＜ 0.05 ).The PIDS at T4 and T6were higher than at T3and T5in the second and third stages 〔(2.52 vs.1.69,2.12 vs.1.44)scores〕 (P＜0.05).The correlation coefficient between CPOT and PIDS at T3 and T4 in the second stage were 0.49 and 0.58,respectively (P＜0.05),and between CPOT and PIDS at T5 and T6 were 0.52 and 0.59 in the third stage,respectively (P ＜ 0.05),and they both reached moderate correlation.ConclusionsCPOT may be an effective way to assess the degree of pain in elderly patients with mechanical ventilation at present.

Objective To study the change of bone ?-carboxyglutamic acid containing protein(BGP) in serum of rats at the initial stage of skeletal fluorosis caused by fluoride in coal.Methods SD rats were randomly divided into 6 groups (the number of female and male in each group was the same respectively):the control group,the low-dose fluoride group,the middle-dose fluoride added nutrition group,the middle-dose fluoride group,the high-dose fluoride added nutrition group,the high-dose fluoride group.All rats in the experimental groups were fed on the corn collected from the prevalent areas and contained different contents of fluoride respectively for 90-100 days.Content of fluoride in the urine,bone,kidney,BGP in serum,bone mineral density (BMD)and calcium in the bone and urine were determined.Results The fluorosis of the rats became more serious as fluoride intake increased.On the condition of same fluoride intake,the fluorosis could be relieved if nutrients added.BGP in serum of rats in each experimental groups had a increase trend,at the earlier stage,BGP of the high-dose group was higher than that of the control group (P

Objective To investigate the clinical characteristics,peripheral insulin sensitivity,and β-cell function in patients with ketosis-prone diabetes(KPD).Methods Thirty-one patients with newly diagnosed ketosisprone diabetes were admitted to West China Hospital from January 2004 to December 2009.They were divided into 2 groups according to their body mass index (BMI):OB-KPD (BMI ≥ 25 kg/m2,n =22) and Lean-KPD (BMI ＜ 23 kg/m2,n =9).10 patients with newly-onset type 2 diabetes free from ketosis (OB-DM:BMI ≥ 25 kg/m2,n =10) were enlisted as control.Detailed assessments of medical history and symptoms of hyperglycemia were performed.The islet cell antibody (ICA),insulin autoantibody (IAA),anti-glutamic acid decarboxylase antibody (GAD-Ab),fasting plasma glucose,serum insulin,C-peptide and free fat acids concentrations were measured.All of the subjects underwent oral and intravenous glucose tolerance tests,euglycemic-hyperinsulinemia and hyperglycemia clamp test,to evaluate the insulin secretion and insulin sensitivity respectively.Insulin sensitivity was determined by glucose disposal rate (GDR) of steady state during euglycemic clamp and acute insulin secretion was calculated by insulin area under curve(AUCins 0-10 min) during IVGTT.Maximal insulin secretion was determined by glucose infusion rate (GIR) and serum insulin concentration of steady state during hyperglycemic clamp test.Results Age,sex,duration of diabetes were matched among groups.A family history of diabetes was strongly associated with those patients with obesity,compared with lean ketosis prone diabetes(16/22 vs 1/9).GDR was (4.91 ± 1.82) mg · kg 1 · min-1 in subjects with OB-KPD,being lower than that in Lean-KPD patients[(6.26 ± 1.89) mg · kg 1 · min-1] and OB-DM group[(6.78-± 1.69) mg · kg 1 · min-1,P＜0.01].Serum insulin and C-peptide in OB-KPD patients were higher than Lean-KPD patients.Area under the insulin curve [AUCins0-10min (183.86 ± 31.1) mIU/L] and GIR[(2.65 ±1.53) mg · kg-1 · min-1] in OB-KPD patients were lower than those in OB-DM group[(697.06-± 231.9) mIU/L,(6.53 ± 2.21)mg · kg 1 · min-1,P＜0.0 1],but slightly higher than the Lean-KPD group [AUCins0 10min (92.1 ±29.8) mUU/L,GIR (2.55 ± 1.49) mg · kg 1 · min-1,P＜0.05].Glucose disposal rate (GDR) was strongly associated with casual plasma glucose (r =-0.502,P＜0.01),HbA1C(r =-0.553,P＜0.0 1) and FFA eoneentrations (r=-0.504,P＜0.01) on admission.Conclusions Insulin resistance and β-cell dysfunction coexist in all KPD patients.OB-KPD patients exhibit more severe insulin resistance,while Lean-KPD patients have lower insulin secretion.KPD patients had severe hyperglycemia,hypertriglyceridemia,and high plasma FFA levels on admission,suggesting that hyperglycemia and elevated FFA levels could result in serious insulin resistance,β-cell dysfunction,and diabetic ketosis in patients with KPD.

ObjectiveTo investigate the short-term effect of health education intervention on the recovery of new schizophrenia patients. Methods82 patients were randomly divided into observation group, in which patients accepted routine antipsychotic medication, general nursing and system health education intervention, and control group, in which patients accepted antipsychotic medication and general nursing. Brief psychiatric Rating Scale (BPRS) and Positive And Negative Syndrome Scale (PANSS) were used to assess the effects. ResultsThere was no difference in the score of every factor before intervention (P>0.05), but it became different after intervention (P<0.01 or P<0.05). ConclusionHealth education intervention can improve the effect on schizophrenia.

To solve separating problem of natural soda, fifty-seven strains screened from soil, floul water and activated mud were of flocculating activity. Two strains of bacteria, which were screened from above mentioned strains have higher activity and better steady than the whole culture liquid of bacteria was observed that its flocculating use to natural soda was strong and the mean flocculating rate of two strains were 79.80% and 87.% respectively.
