ObjectiveTo investigate the effect of nursing intervention on medication compliance of patients with climacteric dysfunctional uterine bleeding. Methods84 patients with climacteric dysfunctional uterine bleeding in our hospital from April 2009 to April 2011 were treated,they were randomly divided into the control group and the observation group with 42 cases in each group.The control group was given routine care during the course of medication,the observation group was given pertinent nursing intervention based on the routine nursing.The medication compliance and treatment effect were retrospectively analyzed. ResultsAmong 42 cases in the observation group,40 cases (95.2％) followed the doctor's advice,41 cases (97.6％) visited on time,3 cases (7.1％) failed the treatment.In the control group,30 cases (71.4％) followed the doctor's advice,25 cases(59.5％) visited on time,14 cases(33.3％) failed the treatment.The observation group was better than the control group. ConclusionsHormone treatment for patients with climacteric dysfunctional uterine bleeding can obtain desired therapeutic effect,but method of medication was more complicated.Nursing intervention during medication course can significantly improve medication compliance and treatment effect,which is of great clinical significance.

Objective To investigate the effects of exercises on expressions of retinol binding protein-4 (RBP4)in serum and phosphatidylinositol 3 kinase(PI3K)in skeletal muscles of insulin-resistant(IR)rats induced by diets.Methods A total of 30 Wistar rats were randomly divided into 3 groups:normal control group fed with normal diet,IR and exercises groups with high sugar and high fat diet.After 8 weeks,the Wistar rats in exercises group took swimming training for 6 weeks and all groups kept their assigned diets.At the end of 14-week experiment,the body weight(BW)of rats were measured,the general behaviors of rats were observed and then sacrificed.Rats' blood were sampled for measuring the levels of glucose(FPC)and serum RBP4,insulin(FINS),HDL-C,LDL-C,TG,TC.The indexes of IR(HOMA-IR)were calculated.The levels of RBP4 in serum were measured with ELISA technique.The ratios of visceral fat content to BW were calculated too.Immunohistochemistry method was applied to detect the expression levels of PI3K in skeletal muscle.Results(1)The levels of RBP4,TC,TG,FPG in serum in exercises group were lower than those in IR group significantly;the visceral fat content,ratio of visceral fat content to BW,FINS,RBP4,LDL and HOMA-IR in serum increased significantly in IR group after 6 weeks feeding compared with normal control group and exercises group(P＜0.01);the levels of HDL in serum in IR group were lower than those in the other two groups.(2)The expression levels of PI3K in skeletal muscles in exercises group were significantly higher than that in IR group(P＜0.01).(3)In a multiple stepwise regression analysis,FINS,ratio of visceral fat content to BW,LDL and HOMA-IR were correlated with RBP4 positively;HDL and PI3K were correlated with RBP4 negatively.Conclusion Exercises could downregulate the level of RBP4 in serum and upregulate the level of PI3K in skeletal muscles of IR rats.This effect was important for improving the organism sensibility to insulin.

As a treatment of noninvasive,safe,effective,and easy to operate,external counterpulsation has been widely used in the treatment of ischemic heart disease.The treatment mechanism of external counterpulsation may improve collateral circulation and hemodynamics.Therefore,it can provide a new measure for the treatment of cerebrovascular disease.However,the efficacy and safety of external counterpulsation in the treatment of ischemic stroke still need to be confirmed by a large sample clinical trial.

The oxidation-reduction properties,relative to the Fe(Ⅲ)/Fe(Ⅱ) conversion,of horseradish peroxidase(HRP)in surfactant films at edge-plane pyrolytic graphite(EPG)electrode have been investigated by using direct electrochemical methods.Cyclic voltammograms for DDAB/HRP/CME(chemically modified eelctrode),DMPC/HRP/CME,DHP/HRP/CME at 2V/s in phosnhate buffer solution (pH 7.O) show one pair of reversible,reproducible redox peaks. The redox potentials (E1/2) in DDAB/HRP/CME,DMPC/HRP/CME and DHP/HRP/CME are-0.212V,-0.330V,-0.381V respectively. Experimental result indicated that the membranes,especially the positively charged one,providing special film environment,might interfere in the protein-electrode electron transfer process. The electron transfer processes of HRP were described in the absence and in the presence of hydrogen peroxide.There are good linear relationships between the currents and the H2 O2 concentration using all the three CMEs.The results obtained are of potential value for basic and applied bioelectrochemistry and represent an opportunity to build the third generation of biosensors.

Objective To investigate the changes in cortical excitability and inhibitory circuits of patients with Alzheimer's disease (AD) or behavioral variant frontotemporal dementia (bvFTD) using transcranial magnetic stimulation (TMS).Methods Forty-four patients with AD,30 patients with bvFTD and 44 healthy controls were enrolled in the study.The epidemiological data of all subjects were collected.Each participant received a neurological evaluation and neuropsychologic tests which included Mini-Mental State Examination (MMSE),Activities of Daily Living (ADL) and Hamilton Rating Scale for Depression (HAMD).Neurophysiological evaluations including resting motor threshold (rMT),active motor threshold (aMT) and cortical silent period (CSP) were conducted by means of TMS.Neurophysiological parameters were compared among groups.Results There were significant differences in MMSE,ADL and HAMD assessments among 3 groups,but no significant differences between AD and bvFTD groups.There were significant changes in left rMT(46.52％ ± 8.77％,52.00％ ± 7.30％ and 52.14％ ± 8.27％,F =6.295,P=0.003),left aMT(29.68％ ±7.01％,35.13％ ±8.46％ and 35.39％ ±7.24％,F=7.735,P=0.001) and right rMT(47.82％ ±7.94％,52.07％ ±8.77％ and 53.12％ ±8.61％,F=4.772,P=0.010) among 3 groups.AD patients showed significantly reduced left rMT and aMT comparing to bvFTD patients (P =0.017 and 0.008 respectively) and controls (P =0.005 and 0.002 respectively).In addition,AD patients had a significant decrease in right rMT comparing to controls (P =0.011).There were no statistically significant differences in TMS parameters between bvFTD patients and controls.Conclusions AD is associated with hyperexcitability of the motor cortex,whereas the lack of changes in motor cortical excitability is found in bvFTD.TMS technique may be helpful in differential diagnosis between AD and bvFTD.

Objective To verify the genes screened by the polymerase chain reaction (PCR) chip of cell cycle. Methods The colon cancer cells SW480 were randomized into two groups, the test group (with gastrin stimulation) and con-trol group (without gastrin stimulation). The method of Western blot was used to detect the expression of calcylin binding pro-tein/Siah-1 interacting protein (Cacybp/SIP) before and after gastrin stimulation. The differential expression genes, cyclin de-pendent kinase 8 (CDK8) and cyclin dependent kinase subunit (CKS2), were verified by using real-time quantitative PCR (qRT-PCR). Results It was found that before the stimulation, CacyBP/SIP was located and expressed in cytoplasm, and then in both cytoplasm and nucleus after gastrin stimulation. The qRT-PCR results of CDK8 and CKS2 genes were consis-tent with those of microarray detection. The expressions of CDK8 and CKS2 were up-regulated (P < 0.05). Conclusion The stimulation of human gastrin can lead to the nuclear translocation of CacyBP/SIP. The results of microarray are reliable, and the differentially expressed genes screened through gene chip deserve further study.
