ObjectiveTo investigate sleep disorder of patients with depression and find out the regularity.Methods78 depression cases in the east-region of Shenyang were evaluated by Pittsburgh Sleep Quality Index (PSQI) questionnaire and mental health symptom checklist-90 (SCL-90). The results were contrasted with normal control group.Results63 depression cases (80%) had sleep disorder (PSQI scores≥8) and were significantly higher than normal control group. The PSQI evaluation showed that sleep quality, enter-sleep time, sleep efficiency, sleep disorder, hypnotige drugs, function of daytime and total scores of PSQI of the depression group were significantly higher than that of normal control group (P<0.05~0.01). The SCL-90 test showed that scores of somatic, obsessive, depressive, anxiety, phobia, paranoid and mental-illness, etc. and total quota of bad-sleep quality group were significantly higher than that of the fine-sleep quality group (P<0.05~0.01).ConclusionDepression patients have significantly descent in sleep quality, latter is often closely related to the mental psychotic expressiveness of somatic, obsession, depression, anxiety, phobia, etc.

The contents of coumarins in the sulfur fumigated Angelicae Dahuricae Radix (Baizhi, ADR) were reduced significantly. To achieve the quality control of ADR, the qualitative identification of sulfur fumigated ADR and quantitative model of imperatorin content should be established. The near-infrared (NIR) spectrograms of non-sulfur and sulfur fumigated ADR were collected by NIR diffuse reflectance spectroscopy technology and pretreated by the method of first derivative derivation and vector normalization. The Ward's Algorithm method was used for the cluster analysis. The non-sulfur and sulfur fumigated ADR can be quickly identified in the range of 8,806. 0-3 811.0 cm(-1) based on the cluster analysis. The NIR quantitative model of imperatorin was established by the contents of imperatorin determined by HPLC in combination with partial least squares regression analysis. According to the calibration model established in this study, correlation coefficients (R2), the root-mean-square error of cross-validation (RMSECV), and the root-mean-square error of prediction (RMSEP) for imperatorin were 0.982 8, 0.006 8, 0.011 8, respectively. The quantitative model of imperatorin can be applied to determine the content of imperatorin in ADR accurately.

Objective To investigate the dynamic changes of glutamic acid(Glu) levels,ATP levels,free calcium ion,mitochondrial membrane potential,apoptosis related to mitochondrial pathways of apoptosis and Na+-K+-ATPase activity,and explore the mechanism of mitochondrial pathways of apoptosis in neuron injury of rats with kainite acid(KA)-induced epilepsy.Methods KA-induced epilepsy model was induced by injection of KA into the hippocampus.Forty SD rats were randomly divided into 2 groups: control group(n=8)and KA group(6 h,1 d,3 d,7 d,n=8).The concentration of Glu in hippocampus CA3 area was detected by high performance liquid chromatography.The apoptosis of hippocampus neurons and the concentration of Ca2+ were assayed by flow cytometry.The mitochondrial membrane potential was detected by JC-1.The Na+-K+-ATPase activity was examined.Results 1.The concentration of Glu in hippocampus increased at 3 d after KA injection and reached the peak after 7 d injection.2.The concentration of Ca2+ level,mitochondrial membrane potential,and the number of apoptosis neurons were significantly increased,wherase the mitochondrial membrane potential decreased after 6 h of KA injection,7 d after KA injection,and the changes were more severe.3.In the hippocampus,the activities of the Na+-K+-ATPase significantly decreased at 1 d after KA injection,and they decreased more over at 7 d after KA injection.4.The levels of ATP,mitochondrial membrane potential,and the activity of the Na+-K+-ATPase were negatively correlated with the neuron apoptosis(Pa

Objective To examine the relationship between plasma homocysteine level and status of congestive heart failure. Methods Plasma homocysteine level was determined in 106 patients with congestive heart failure(CHF).Among them,40 patients were diagnosed as having recent onset of CHF(group 1) and the remaining 66 were receiving conventional treatment(group 2).Thirty healthy subjects were served as a control group. Results(The plasma) homocysteine levels in group 1,group 2 and the control group were(14.87?5.22),(13.25?5.45) and((7.52)?1.73) ?mol/L,respectively.The plasma homocysteine level was significantly higher in group 1 and group 2 than in the control group(P
