Objective To analyze the correlation between clinical compliance and peritoneal dialysis treatment outcome and quality of life on end-stage renal disease patients with high and low clinical compliance.Methods Total of 137 continuous ambulatory peritoneal dialysis (CAPD) patients of end-stage renal disease were collected in second-class hospital in Weifang by convenience sampling,and divided into high and low clinical compliance group (68 patients in each)according to ESA score.SF-36,dropout rate,fatality rate,infection rate and rehospitalization rate were used to estimated,and Cox multi-factor regression model was used to analyze correlation between therapy outcome and risk factors.Results 61 CAPD patients (44.52％) were dropout,with 23 cases (37.70％) by death.The dropout rate without death(11.8％,44.12％),fatality rate (7.4％,26.5％) and infection rate(8.8％,38.2％)had significant difference between high and low clinical compliance group (P＜0.05).The SF-36 scores of 8 dimension also had significant difference between the two groups.Cox multi-factor regression model showed that clinical compliance was an important risk factor of therapy outcome and death(HR =1.68,P＜0.05).Conclusion Clinical compliance is an important risk factor of therapy outcome,and should be listed as efficacy monitoring index of peritoneal dialysis and the target of improving the curative effect of the intervention.

ObjectiveTo explore the difference of the oxytocin Levels and cortisol levels between major depression patients and normal controls,and the relationship of symptoms severity of major depression with oxytocin levels and cortisol levels.MethodsTwenty 18 ～ 45years old major depression patients and twenty six normal controls were tested by an enzyme-linked immunosorbent assay to evaluate the oxytocin levels and cortisol levels,and the Hamilton Rating Scale for Depression-17 item was used to evaluate the symptoms severity of depression in patient group.ResultsMann-Whitney test showed there were significantly differences in oxytocin level between patients and controls ( ( 213.60 ± 164.29 ) pg/ml vs ( 112.27 ± 101.21 ) pg/ml,z =- 2.306,P =0.021 ),but there were no significantly differences in cortisol level between two groups.Within the depressive sample( (0.131± 0.089) vs (0.107 ± 0.077 ) pg/ul,z =- 0.920,P =0.358 ),the severity of depressive symptom was positive correlated to the value of oxytocin ( r=0.599,P=0.005) and cortisol( r=0.691,P=0.001 ),the value of oxytocin was also positive correlated to the value of cortisol( r =0.743,P ＜ 0.01 ),Multiple liner regression analyses showed that the value of oxytocin is an impact factor of the severity of depression.( adjusted R2 =0.358,F =11.578,P =0.003 ).ConclusionThis study indicated that the value of plasma oxytocin maybe significantly differences between depression and normal controls and the plasma oxytocin level maybe a factor which influence the severity of major depression,the relationship of the cortisol value and the severity of depression can not be confirmed.

Objective:To investigate the effects of Daidzein on behavior of chronic stress depression rats and the expression of hippocampal brain-derived neurotrophic factor ( BDNF ) , neuropeptide Y ( NPY ) and non-specific immune regulation.Methods: 40 healthy adult male SD rats with body weight(210±19)g,clean grade,were chosen and fed with 1%sucrose solution for 4 d to change drinking habits.On the fifth day rats were subjected to water deprivation for 24 h without fasting.On the sixth day rats were fed with 1%surcrose solution.4 h later, preference of 1% surcrose solution was examined.According to the 1% sucrose solution preference and weight rats were randomly divided into 4 groups,normal control group(CG),model control group,(MG),fluoxetine group(FG,10.0 mg/kg),daidzein group(DG,80.0 mg/kg).At the same time of establishing model,rats were administered orally once a day for 32 d.The depression model was established by chronic unpredictable mild stress model and separation.The behavioral changes of the rats were observed, and expression of BNDF in hippocampus and NPY was measured by Western blot technology and immunohistochemistry.It was observed the proliferation function of lymphocytes,spleen index,the number of peripheral blood leukocytes and antibody-secreting cell function.Results: Compared with the normal control group(CG),the weight of rats with chronic stress protocol was lower, 1%sucrose consumption decreased,scores of rats in the open field test dropped significantly,the immobility time in the forced swimming test prolonged,the level of expression of BNDF and NPY decreased,all the differences above were statistically sig-nificant(P<0.01).Compared with model group,weight of rats in fluoxetine treatment group(FG) and daidzein treatment group(DG)in-creased,sugar consumption,scores in the open field test and the levels of expression of BNDF and NPY significantly increased,the differences were statistically significant( P<0.05 or P<0.01 ).The number of peripheral blood leukocytes and antibody-secreting cell function and proliferation of lymphocytes force in daidzein treatment group was significantly higher than the model group,daidzein dose spleen index was significantly higher than the model group(P<0.01).Conclusion: The daidzein can antagonize depressive symptoms in chronic stress mice,daidzein may increased content of BDNF in hippocampus and NPY protein, and enhanced the role of humoral immune response and lymphocyte proliferation in rats with chronic stress model.The mechanisms of antidepressant effects of daidzein might be related to the increase of content of BDNF in hippocampus and NPY protein and non -specific immune regulation.

The relationship between bone mineral density (BMD) and Zn, Cu, Ca levels in the meal and hair of urban and rural elderly people were studied. 470 subjects above 60 years old (urban 205 and rural 265), 178 males with an average age of 65.70 +/- 3.48 and 292 females with an average age of 65.90 +/- 4.02, were inquired. The BMD and Zn, Cu, Ca levels in the meal and hair were measured. The detected BMD in urban and rural female old people was significantly lower than that of the males; The contents of Ca and Zn in the meal of the urban females were significantly lower than those of the urban males; The Ca, Zn in the meal and Zn in the hair of the rural females were significantly lower than those of rural males (P < 0.05 or 0.01). The BMD, Ca intakes, Ca and Zn in the hair of the rural old people were significantly lower than those of the urban old people (P < 0.05 or 0.01). There was a correlation between BMD with the Ca, Zn of the hair and dietary Ca, Zn, Cu or between dietary Zn with Ca, Zn in the hair and Ca, Cu intakes. The Zn, Cu and Ca levels in the meal nutrients were correlated with BMD to some degrees. Lack of Ca and Zn in the meal can cause the reduction of BMD.

Taking " harmony of body and spirit" as the theoretical core in Huangdi Neijing and the functional nature and executive structure of the five emotions system as clues, this paper explores and analyzes the relevant theories of the five emotions system in ancient Chinese medicine literature. It is found that the five emotions system is a highly ordered and integrated collection of five functional states. It often resides in the five zang viscera, it operates between the meridians and the xuanfu through the elevation and movement of the qi, and it is the pivotal point for the operation of the qi and blood of the organism, the interactive conduction of information, and the unity of form, emotion, and qi. Therefore, this paper starts from the point of view of system science. It is proposed that the primordial spirit exercises control over the five emotions and the five emotions provide nutrition to the primordial spirit, and that the two are not " islands of information" but have a dynamic and hierarchical internal connection. The executive structure of the five emotions system, namely, the meridians, the xuanfu, and the five zang viscera, is the pivot, and it is recognized that the operation of the five emotions system is a process with self-organizing characteristics and orderly and eternal motion. We think of the qi, blood, ying, and essence as the basis of occurrence, the meridian as the execution channel, and the xuanfu as the place for the spiritual mechanism to enter and exit; the five zang viscera serve as a dwelling place, and ministerial fire serves as the source of energy. This paper serves as reference for future research related to the executive structure of the five emotions system of traditional Chinese medicine.
