Objective To evaluate the protective effects of methylprednisolone combined with dexmedetomidine of cardiac valve replacement in patients with brain cognitive function under cardiopulmonary bypass (CPB).Methods Sixty patients for heart valve replacement in Affiliated Hospital.Inner Mongolia Medical University were randomly divided into four groups (n =15 each):group A control,methylprednisolone group (group M),dexmedetomidine group (Group D) and methylprednisolone combined with dexmedetomidine group (group B).After the induction of anesthesia,the patients were endotracheally intubated and mechanically ventilated.Methylprednisolone 20mg/kg was administered to the CPB circuit prime in group M.A loading dose of dexmedetomidine 1 μg/kg was pumped intravenously over 10 minutes after induction,followed by continuous infusion at 0.05μg/(kg · h) until the end of operation in group D.A loading dose of dexmedetomidine 1 μg/kg was pumped intravenously over 10 minutes after induction,followed by continuous infusion at 0.05μ g/(kg · h) until the end of operation and methylprednisolone 20mg/kg was also administered to the CPB circuit prime in group B.At the same time the equal volume of normal saline was given in group A.After induction (T1),CPB instantly (T2),CPB 30min (T3),l0min after CPB(T4),at the end of operation(T5),6h after CPB (T6),the jugular bulb venous blood samples were taken for testing the serum concentrations of interleukin-6 (IL-6),interleukin-10 (IL-10),S100βprotein and neuron-specific enolase (NSE) using the method of ELISA.Simplified mini-mental state examination (MMSE) is used to assess the cognitive function of patients in pre-operation and 2days,3days as well as 7days after operation.Results At T1-6,IL-6,S100 protein and NSE in group M,group D and group B were significantly lower than those in control group,IL-10 was higher than that in control group,and there was significant difference (P < 0.05).In B group at all time points IL-6 、S100 protein and NSE were lower than those in other groups,IL-10 was higher than other groups,and there was significant differences (P < 0.05).The incidence of postoperative cognitive dysfunction in group M,group D and group B was higher than that in control group,and the incidence of cognitive dysfunction in B group was lowest,and there were significant differences (P < 0.05).Conclusion Methylprednisolone and dexmedetomidine can effectively reduce the concentration of IL-6,S100 protein and NSE in cardiopulmonary bypass,reduce brain injury and the incidence of postoperative cognitive dysfunction.The protective effect on cerebral injury is better when using dexmedetomidine combined with methylprednisolone under cardiopulmonary bypass (CPB).

Objective:To describe health service use and trend of treatment and rehabilitation rates among people with psychiatric disability from 2007 to 2013.Methods:Data collected by the 2006 Second China National Sample Survey and the 2007-2013 National Disability Monitoring Survey were utilized and analyzed.The 2006 National Sample Survey on Disabilities investigated 2 526 145 non-institutionalized representative civilians in 734 counties across mainland China.Psychiatric disability was diagnosed by clinical psychiatrists according to ICD-10 and WHO DAS Ⅱ criteria.The 2007 to 2013 National Disability Monitoring Survey selected 1 to 2 study sites among each of the 734 study counties that had been investigated by the Second China National Sample Survey.Information on living conditions,health service use,education and employment were recorded.Results:The data showed that treatment and rehabilitation rates for people with psychiatric disability had largely increased from 2007 to 2013 among adults aged 18 years or older,with the treatment and rehabilitation rates from 49.52% and 21.8% to 66.9% and 58.7% respectively,and the rates among those with 17 years or younger from 23.5% to 43.9%.However,with regard to the effect of the treatment and rehabilitation services,a much larger proportion of people with psychiatric disability reported that the effect was soso instead of good or very good.In addition,among those who received rehabilitation service,most received day care or psychotherapy service,only less than 8% participated work therapy,farming therapy or working skill trainings.Conclusion:The results suggest treatment and rehabilitation rates among people with psychiatric disability are largely increased from 2007 to 2013,while the quality of the service needs further attention.

AIM: To investigate the relationship between bone metabolism and serum leptin in type 2 diabetes mellitus (T2DM) postmenopausal female patients. METHODS: Totally 80 postmenopausal female inpatients with T2DM (according to the diagnostic criteria of WHO1999) aged 60-80 years from Yangpu District Central Hospital who gave informed consent were enrolled in the present study from January 2004 to January 2006. Exclusive criteria: Subjects who taking medications such as estrogen, glucocorticoid, or calcium or phosphorus metabolism, having a history of gastrointestinal surgery and other endocrine diseases were excluded. Each subject's age, duration, menopausal period, body mass index (BMI), fasting glucose (oxidation enzyme method), hemoglobin A1c (HbA1c) (microcolumn affinity chromatography) and leptin levels (ELISA) were measured. Ultrasound characteristics of the right heel bone were measured with ultrasound bone densitometer (French UPIS3000) to identify the speed of sound (SOS), broanband ultrasound attenuation (BUA) and stiffness (STI). STI was equal to 0.67?BUA+0.28?SOS-383. Linear correlation analysis was performed in ultrasound index, general index and leptin level. RESULTS: A total of 80 postmenopausal female inpatients with T2DM were involved in the result analysis. BUA, SOS and STI were negatively related with age (r =-0.342 to -0.298,P all
