Objective To investigate the impact of Friedman family intervention model on the personal life ability and psychological status of caregivers of early Alzheimer's disease patients.Methods 66 Alzheimer's disease patients,according to the random sequence,were divided into the study group and the control group with 33 patients in each group respectively.The control group received routine geriatric care,the study group was given Friedman family intervention model on the basis of routine geriatric care.Two groups were estimated with Life Scale Index and ADL before intervention and two months after intervention respectively,and the matching caregiver were evaluated with Symptom Checklist-90 (SCL-90).Results Compared with the control group,the quality of daily life after the intervention of the study group was significantly improved,and the differences of daily living skills between two groups were statistically significant.The differences of the SCL-90 total score and depression,anxiety,somatization,interpersonal factor scores of caregivers between the two groups were statistically significant after two months of intervention.Conclusions The application of Friedman family intervention model plays a significant role in the improvement of the quality of daily life and daily living skills in patients with Alzheimer's disease,and can improve the psychological status of the caregivers of AD patients.

Hyperhomocysteinemia, which is an independent risk factor for atherosclerosis, may cause aberrant methylation and dysregulation of gene expression, but the characteristics of the aberrant methylation and its key links involved in its pathogenic mechanisms are still poorly understood. The effect of hyperhomocysteine on DNA methylation in vascular smooth muscle cells, its characteristics and the underlying mechanism of Hcy-induced changing in DNA methylation patterns were investigated. Clinical relevant concentrations of homocysteine was added into the cultured vascular smooth muscle cells of the Homo sapien umbilical vein for 24 h. The level of SAM and SAH was detected by HPLC. The activity of SAH Hydrolase was detected by real-time quantitative reverse transcription-PCR and Western blotting analysis. The level and patterns of DNA methylation were measured by endogenous C-5 DNA methyltransferase(C-5 MT-ase) activity and capacity of genomic DNA to accept methyl groups and methylation-dependent restriction analysis. The results indicated that an increased Hcy concentration induced elevated SAH, declined SAM and the ratio of SAM/SAH, reduced expression of SAH Hydrolase, but increased activity of C-5MT-ase. The methylation status of gDNA analyzed by methyl-accepting capacity of gDNA uncovered a demethylation process in gDNA, or homocysteine-caused hypomethylation in gDNA.With different methylation-dependent restriction endonucleases, the aberrant demethylation was found to prefer C↓CGG sequences to CpG islands. The impacts of different dosage of Hcy showed that the varied detrimental effects of Hcy could be attributed to different concentrations via different mechanisms. In mild and moderate hyperhomocysteinemia, the Hcy may primarily influence the epigenetic regulation of gene expression through the interference of transferring methyl-group metabolism, while in more higher Hcy concentration, the notorious impacts may be more directly caused via oxidative stress, apoptosis, inflammation etc.

The levels of low-density lipoprotein(LDL)glycation from control group,diabetic HbA1C < 7.0%,and HbA1C>7.0% groups were(17.7±2.31),(34.29±5.73),and(48.79±7.82)Glycogroups/LDL by fluorimetry.The LDL binding to its receptor in three groups were(37.65±5.20),(27.36±4.34),and(15.07± 2.23)ng/mg cell protein measured by enzyme-linked immunoreceptor assay.The glycated levels in two diabetic groups were higher than that in control group,and higher in HbA1C>7.0% group than in HbA1C<7.0% group(all P< 0.01).The results of LDL binding capacity to its receptor were just the opposite.

Objective To evaluate the role of mitochondrial permeability transition pore (mPTP) in attenuation of myocardial ischemia-reperfusion (I/R) injury by sufentanil postconditioning in rats.Methods Sixty male Sprague-Dawley rats,aged 14-15 weeks,weighing 350-420 g,were randomly divided into 4 groups (n =15 each):sham operation group (group S),group I/R,cyclosporin A group (group CP) and sufentanil postconditioning group (group SP).Myocardial I/R was produced by occlusion of left anterior descending branch of coronary artcry for 30 min followed by reperfusion.In groups CP and SP,cyclosporin A 5 mg/kg and sufentanil 1 μg/kg were injected via the jugular vein at 5 min before reperfusion respectively,while the equal volume of normal saline was injected in group I/R.At 10 min of reperfusion,hearts were excised,the myocardial mitochondria were immediately isolated and the activity of mPTP was measured by spectrophotometry.MAP and HR were recorded at 30 min of equilibration,at 30 min of ischemia and at 120 min of reperfusion and rate-pressure product (RPP) was calculated.Arterial blood samples were obtained at 120 min of reperfusion for determination of the plasma cardiac troponin Ⅰ (cTnⅠ) concentration.The animals were then sacrificed for determination of infarct size (IS) and area at risk (AAR),and IS/AAR was calculated.The mitochondrial ultra-structure was examined with electron microscope.Results Compared with group S,the mPTP activity and plasma cTnI concentration were significantly increased,and MAP and RPP were significantly decreased in the other three groups (P ＜ 0.05).Compared with group I/R,the mPTP activity,plasma cTnI concentration and IS/ARR were significantly decreased in groups CP and SP,and MAP was significantly increased in group CP (P ＜ 0.05).Compared with group CP,MAP was significantly decreased (P ＜ 0.05),while no significant change was found in the other indexes in group SP (P ＞0.05).Significant mitochondrial swelling,and disruption and disappearance of cristae were showed in I/R group.The mitochondrial structure was more complete in CP and SP groups than that in group I/R,and the disrupted cristae were found in a small number of mitochondria in CP and SP groups.Conclusion The mechanism by which sufentanil postconditioning reduces myocardial I/R injury is related to inhibition of mPTP opening in rats.

Objective To investigate the effect of type 2 diabetes mellitus (DM) on the attenuation of myocardial ischemia-reperfusion (I/R) injury by sufentanil postconditioning in rats.Methods Male pathogen-free Sprague-Dawley rats,weighing 160-180 g,were used in the study.A model for type 2 DM was established by the feeding of high-fat diet-induced insulin resistance and intraperitoneal streptozocin 35 mg/kg.DM was confirmed by blood glucose level ≥ 16.7 mmol/L one week after injection.Eighteen type 2 diabetic rats were randomly divided into 3 groups (n =6 each):DM sham operation group (DM-S group) ; DM-I/R group; DM sufentanil postconditioning group (DM-SP group).Another 18 healthy nondiabetic rats were chosen and randomly divided into 3 groups (n =6 each):nondiabetes mellitus sham operation group (NDM-S group) ; nondiabetes mellitus I/R group (NDM-I/R group) ; nondiabetes mellitus sufentanil postconditioning group (NDM-SP group).Myocardial I/R was induced by 30 min occlusion of the left anterior descending branch of coronary artery (after 30 min of equilibration) followed by 120 min of reperfusion.Sufentanil 1.0 μg/kg was injected via the right jugular vein 5 min before reperfusion in NDM-SP and DM-SP groups.MAP,SP and HR were recorded immediately before ischemia,at 30 min of ischemia and at 120 min of reperfusion and rate-pressure product (RPP) was calculated.Arterial blood samples were collected at 120 min of reperfusion for measurement of plasma cardiac troponin Ⅰ (cTnⅠ) concentration.The rats were then sacrificed for determination of the myocardial infract size.Results MAP and RPP were decreased,while the plasma cTnl concentration was increased during reperfusion in diabetic and nondiabetic rats.Sufentanil postconditioning decreased the myocardial infract size and plasma concentrations of cTnⅠ,and increased MAP and RPP during reperfusion in nondiabetic rats,but had no effect on the parameters in diabetic rats.Conclusion Type 2 DM interferes with sufentanil postconditioning-induced myocardial protection in rats.

Objective To investigate the expressions of CD147,MMP-9 and TIMP-1 in human gliomas and analyze the correlations.Methods Expressions of CD147,MMP-9 and TIMP-1 were assessed in paraffin-embedded specimens collected from 78 gliomas and 12 benign brain lesion tissues by immunohistochemistry.Real time PCR was performed to detect CD147 mRNA expression.Results The positive rates of CD147,MMP-9 and TIMP-1 expression were 62%(48/78),71%(55/78),59%(46/78) respectively.We found a significant positive correlation between CD147,MMP-9,TIMP-1 expressions and poor gliomas differentiation by Spearman analysis(rs=0.2671-0.5631,Ps＜0.01).There was also a significant positive correlation between CD147 and MMP-9 expression(rs =0.3576,P＜0.01).In addition,the expressions of CD147(47% vs.80%,x2=9.510),MMP-9(56% vs.89%,x2=10.702),and TIMP-1(49% vs.71%,x2=4.138) were significantly higher in advanced gilomas than early gliomas(Ps＜0.05).The relative expression levels of CD147 mRNA in gliomas of Ⅰ to Ⅳ pathological grades were 0.15,0.27,0.46,0.78 respectively.Conclusion The expressions of CD147,MMP-9 and TIMP-1 were important characteristic of gliomas,which may serve as biomarkers in the glioma prognostic prediction.

Objective To investigate the present situation of institutes of rehabilitation medicine in Guangxi. Methods From March to July, 2015, all 287 hospitals in Guangxi were investigated with the Human Resource Statistics of Guangxi Rehabilitation Medicine Depart-ment and the Specialist Questionnaire of Guangxi Rehabilitation Medicine Department by E-mail through the local Health and Family Plan-ning Commissions. Results There were 125 rehabilitation medicine departments with 2146 personnels in Guangxi, 0.2 therapists per bed in average. The proportion was 1∶0.725 for rehabilitative physicians to therapists;1∶1.92∶3.14 for senior, intermediate and primary title for physicians;1∶8∶63 for therapists and 1∶5.6∶18.9 for nurses. About 91.3%of the department of rehabilitation medicine was in the tertia-ry hospitals and was able to provide the services of physical therapy, occupational therapy, speech therapy, swallowing rehabilitation, cogni-tive rehabilitation, psychological therapy and rehabilitation engineering, and so on. Conclusion Rehabilitation has made a big progress com-pared with that in 2009 in Guangxi, in term of institutes, human resources and the service ability. However, the distribution of institutions and human resources remains unbalanced.

Objective To evaluate the accuracy of anesthesia index (AI) for monitoring depth of sedation induced by propofol.Methods Thirty patients of both sexes,aged 41-64 yr,with body mass index of 20-30 kg/m2,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective surgery under general anesthesia,were enrolled in the study.Propofol was given by target-controlled infusion (TCI) with the initial target effect-site concentration (Ce) of 1.2 μg/ml using Marsh pharmacokinetic model,and then the Ce of propofol was increased in 0.3 μg/ml increment,and Observer's Assessment of Alertness/Sedation (OAA/S) score was evaluated.OAA/S score was 5 before TCI of propofol.When OAA/S score reached 4,3,2 and 1 in turn during TCI of propofol,the bispectral index (BIS),AI and corresponding Ce were recorded.Results The correlation coefficients of BIS,AI and Ce levels with the OAA/S scores were rBIS-OAA/S =0.962,rAI-OAA/S =0.960 and rce-OAA/S =-0.795,respectively (P＜0.05).The correlation coefficients of BIS and AI with the Ce of propofol were rBIs-ce =-0.736 and rAI-Ce =-0.737,respectively (P＜0.05).There was no significant difference between rBIS-OAA/s and rAI-oAA/S,and between rBIS-Ce and rAI-Ce (P＞ 0.05).Conclusion AI can accurately monitor the depth of sedation induced by propofol in adult patients without noxious stimuli and there is no significant change in the accuracy in comparison with BIS.

As a widely recognized public health problem as well as prevalent and challenging to modern society, chronic insomnia is involved in wide brain areas (such as prefrontal cortex, anterior cingulate cortex, amygdala, hippocampus, and thalamus) and emotion-cognition neuro-circuit. It is closely related to the conditioned hyperarousal and the increased information process and/or the impaired inhibitory ability to withdraw from awaking state. Thus, some specific abnormal mode may exist in the emotion-cognition circuit, which is associated with abnormal cognition load, such as repeated retrieval/intrusion of aversive memories during night. Studies through the combination of multiple techniques including psychology, electrophysiology and neuroimaging methods are needed to further enhance the understanding of chronic insomnia.
