RESUMO
Objective Analysis the relationship between influencing factors and self consistency among patients under maintenance hemodialysis. Methods A total of 146 patients under maintenance hemodialysis were investigated , Research tools include: the self-designed basic information questionnaire, Self Consistency and Congruence Scale, The Meaning in Life Questionnaire,and Acceptance Action Questionnaire. One-way anova, correlation analysis,multiple regression analysis were used to analyze the relationship between influencing factors and self consistency. Results The average score of self consistency and congruence was (94.34±16.13). The score of self-stereotype dimension was (21.22±5.16), higher than that of norm of college students (t=5.132,P<0.01).While there was no difference in the other 2 dimensions of self consistency. The predictors of self consistency and congruence included Duration of dialysis, education level, sense of meaning of life, and experiential avoidance of patients,and these explained 55.40% of the total variance. Conclusions Promoting sense of meaning of life and lower experiential avoidance may help to improve self consistency and congruence for patients under maintenance hemodialysis.
RESUMO
Major depression is a public health problem that seriously harms individuals and the society.But one of the major shortcomings of mainstream antidepressant is the delayed onset.Recent series of studies demonstrated that,from a variety of animal models and clinical studies,classic stagnation-removing formula Yue-Ju (Y J) pill has the advantage in rapid antidepressant efficacy,which is similar to the prototype drug ketamine.It has the mechanism of rapid and sustained enhancement of neural plasticity and individual difference in response to YJ pill.The evidence of Gardenia jasminoides (Zhi-Zi) as the monarch component of YJ pill's rapid antidepressant action has also been revealed.The further in-depth research on rapid antidepressant traditional Chinese medicine (TCM) is important for providing the scientific and reliable TCM strategies to treat depression.
RESUMO
Objective To establish a postpartum depression animal model induced by pre-pregnancy stress,assess abnormal maternal depressive-like behavior,observe the expression of disrupted-in-schizophrenia 1 (DISC1) in the hippocampus,and detect serum estradiol and corticosterone.Methods A total of 32 female Balb/c were assigned to two groups using random number table:the control group and the pre-pregnancy stressed group(model group),and the model group was subjected to 3 weeks of chronic restraint stress. After the last stressor,the control group and the model group were housed with a male. About 4 weeks later,the mice gave birth to pups. Then at 3 weeks postpartum,open field test,tail suspension test,and sucrose preference test were carried out. The expressions of DISC1 mRNA and protein of hippocampus were detected by real-time quantitative polymerase chain reaction and Western blot,respectively. The serum levels of estradiol and corticosterone were detected with enzyme linked immunosorbent assay. Results After 3 weeks of postpartum,the model mice showed depression-like behaviors. In the open field test,there was no effect on the total distance moved or time spent in the center field (P>0.05). Immobility in tail suspension test was significantly increased (t=-4.950,P<0.001) and sucrose preference was significantly reduced in model group (t=2.475,P<0.05). There was significant statistical difference between control and model group on the expression of DISC1 mRNA (t=-8.915,P<0.001) and protein (t=-5.004,P<0.01) in hippocampus. There was no significant statistical difference on estradiol and corticosterone between two groups (P>0.05). Conclusion Chronic pre-pregnancy stress can induce dams into postpartum depression.The pathogenesis of postpartum depression may be related to the regulation of DISC1 in the hippocampus.
RESUMO
This study aimed at exploring the mechanism of the rapid antidepressant effects of Yueju pill on depression of Parkinson's disease (DPD).The fast antidepressant effects of Yueju pill in this study was evaluated by behavior tests,such as open field test (OFT),tail suspension test (TST),forced swimming test (FST) and sucrose preference test (SPT) according to the modeling method of subacute DPD in the literature.In vitro experiment was implemented using PC12 cells.Moreover,the protective effects of Yueju pill on 1-methyl-4-phenylpyridinium (MPP+) induced neural injury with the engagement of cAMP response element binding protein (CREB) were expounded.As a result,it was found that the immobility time of the mice in the model group was significantly longer than that in the normal group in TST and FST tests (P ＜ 0.01),and the SPT ratio of mice in the model group remarkably decreased (P ＜ 0.01).In addition,the immobility time of DPD mice was shortened in the FST test after administering Yueju pill (P ＜ 0.05),while the SPT ratio was increased (P ＜ 0.01).Yueju pill took the effects on the third day after a single administration.The phosphorylation of CREB (p-CREB) in MPP+ induced PC12 cells was decreased in comparison with the model group,while the expression of p-CREB was up-regulated with the administration of Yueju pill (P ＜ 0.01).In conclusion,DPD was quickly mitigated after the treatment of Yueju pill,the activation of CREB signaling pathway and its neuroprotective effects may be the mechanism behind it.
RESUMO
OBJECTIVE:To study in vitro anticancer activity of conjugated linoleic acid-gemcitabine conjugate (CLA-GEM). METHODS:IC50 of different tumor cells (breast cancer MCF-7 cell,breast cancer MDA-MB-231 cell,lung cancer A549 cell, small cell lung cancer NCI-H446 cell,glioma C6 cell)were investigated after treated with different concentrations(0.001-100μmol/L)of CLA-GEM and gemcitabine(GEM)for 72 h;survival rates of MCF-7 cell were investigated after treated with above so-lution for 24,48 and 72 h. The dependence of 0.001-100 μmol/L CLA-GEM and GEM to nucleoside transporter was investigated (by IC50)through MCF-7 cells and MDA-MB-231 cells treated with nucleoside transporter inhibitors(NBMPR,100 μmol/L)and di-pyridamole(4 μg/ml). The change of MCF-7 cell cycle was investigated after treated with 1 μmol/L CLA-GEM and GEM for 24 h. RESULTS:Compared with GEM,IC50 of MCF-7,MDA-MB-231 and NCI-H446 cells became lower after treated with CLA- GEM (P0.05). Survival rate of MCF-7 cells de-creased significantly after treated with GEM for 48 h and CLA-GEM for 24 h. Survival rate of MCF-7 cells was the lowest,being 21% after treated with GEM for 72 h,while tumor cells were sacrificed by CLA-GEM completely. Compared with GEM or CLA-GEM,IC50 of MCF-7 and MDA-MB-231 cells increased significantly after treated with NBMPR,dipyridamole combined with GEM (P0.05). Compared with GEM,CLA-GEM could prolong 6% of S stage of MCF-7 cells (P<0.01). CONCLU-SIONS:Compared with GEM,CLA-GEM exhibits significant antitumor activity and rapid action,and it isn’t influenced by nucle-ic acid transportation.
RESUMO
Objective:To prepare fenofibrate PEG2000-DSPE micelles in order to improve the solubility of fenofibrate, and study the oral pharmacokinetics of the micelles in SD rats. Methods:Fenofibrate PEG2000-DSPE micelles were prepared and characterized. The rats were administrated with fenofibrate PEG2000-DSPE micelles and fenofibrate suspension, respectively. The blood samples were collected from eye socket and determined by HPLC. The compartmental pharmacokinetics was analyzed by DAS software. Results:Fenofibrate PEG2000-DSPE micelles were prepared successfully. The mean particle size was (23. 40 ± 3. 62) nm, the drug loading and the entrapment efficiency was (97. 65 ± 3. 32) % and (1. 33 ± 0. 32) %, respectively. The mean plasma concentration-time curves of fenofibric acid were both in accordance with two-compartment mode after oral administration of fenofibrate PEG2000-DSPE micelles and fenofibrate suspension in rats. After the oral administration, AUC(0-24) and Cmax of fenofibrate PEG2000-DSPE micelles was respectively 7-fold and 14-fold higher than that of fenofibrate suspension [(61. 41 ± 5. 71)μg·h·ml-1 vs (8. 49 ± 0. 66)μg·h·ml-1, and (9.67±1.65) μg·ml-1 vs (0.71 ±0.09) μg·ml-1]. The relative bioavailability of fenofibrate PEG2000-DSPE micelles was 723. 3%. Conclusion:The bioavailability and absorption rate of fenofibrate are both increased by the micelles remarkably when com-pared with those of fenofibrate suspension after oral administration. The PEG2000-DSPE micelles served as drug carrier for oral delivery present promising application perspectives.
RESUMO
Aim To identify whether the petroleum e-ther fraction of Gardenia jasminoides Ellis ( GJ-PE ) could effetive exhibit a rapid antidepressant effect and also to investigate the biological mechanism. Methods Tail suspension test ( TST ) , forced swimming test ( FST ) and novelty suppressed-feeding ( NSF ) were used to screen the rapid antidepressant potential of ef-fective fractions of GJ-PE in KM mice at 24 h post a single administration. Tail suspension test ( TST) was also used at 30 min and forced swimming test ( FST ) was used at 2 h to test the initial onset time of effective fractions of GJ-PE in KM mice. Western blot was per-formed to examine the expression of BDNF and p-eEF2 in hippocampus of KM mice at 2 h and 24 h. Results An acute administration of GJ-PE1 decreased the im-mobility time of KM mice in FST at 2 h and 24 h and decreased the latency time in NSF at 24 h. GJ-PE3 de-creased the latency time in NSF at 24 h. GJ-PE4 in-creased the unit food consumption in NSF at 24 h. At 2 h post a single GJ-PE1 treatment, the expression of BDNF was significantly up-regulated while the expres-sion of p-eEF2 was significantly down-regulated. At 24 h post a single GJ-PE1 treatment, the expression of BDNF was significantly down-regulated while p-eEF2 expression was significantly up-regulated. Conclusion GJ-PE1 has the most significant rapid antidepressant potential among the four fractions of GJ-PE. The effec-tive time of GJ-PE1 is 2 h after drug treatment. The mechanism of the rapid antidepressant effect of GJ-PE1 at 2 h is related to the up-regulation of BDNF and down-regulation of p-eEF2 . GJ-PE3 and GJ-PE4 also have some features of rapid antidepressants. GJ-PE2 doesn′t have the rapid antidepressant potential.
RESUMO
Aims To study the effects of diterpenoid pekinenal of Euphorbia pekinensis Rupr. on cell prolif-eration, cell cycle phase and apoptosis of hepatoma SMMC-7721 cells and to probe into its anti-cancer mechanisms. Methods MTT assay was used to inves-tigate the effect of pekinenal on proliferation of SMMC-7721 cells; TUNEL method, Annexin V/PI staining and electron microscopy were employed to observe the cell apoptosis; Flow cytometry was applied to analyze the distribution of cell cycle. Results Proliferation of SMMC-7721 cells was markedly inhibited by pekinenal in a dose-dependent manner; Annexin V/PI staining showed that with the increase of pekinenal concentra-tion, apoptotic rate of SMMC-7721 cells increased sig-nificantly, compared with control group, the difference has significant statistical significance ( P < 0. 01 ) . TUNEL method test results showed that different con-centrations of pekinenal in SMMC-7721 cells could in-duce liver cancer cell apoptotic and apoptotic index ( AI) increased significantly ( P <0. 01 ) with the in-crease of drug concentration. Compared with control group, electron microscope found that after the treat-ment, hepatocyte mitochondrial swelling, endoplasmic reticulum expansion, cytoplasm inclusion body forma-tion, part of the nucleus apoptosis, and the more obvi-ous apoptosis appeared with the increase of drug con-centration. Flow cytometry analysis showed that differ-ent concentrations of pekinenal could all make the cell block in S phase. Conclusion Pekinenal has an obvi-ously inhibitory effect on the human liver cancer cells, and there is significant concentration dependence; Pe-kinenal probably inhibits cancer cell DNA synthesis for the human liver cell cycle arrest in S phase and inhibits the proliferation . It plays a role in liver cancer inhibi-tion by inducing liver cancer cells apoptosis, etc.
RESUMO
Aim Using chronic pre-pregnancy stress to establish a postpartum depression animal model, given a single YG,and acute ketamine was served as control, to explore the pathology of PPD and the anti-depressive mechanism of the YG on the PPD model on AKT/mTOR signaling pathway. Methods Thirty-two fe-male Balb / c were randomly assigned to two groups, the control group ( Control, Con) and the pre-pregnancy stressed group(Model,Mod) , which was subjected to 3 weeks chronic restraint stress. After the last stressor, the pre-pregnancy stressed group was housed with a male. After about 4 weeks later, the mice gave birth to pups. Then at 3 weeks postpartum, we tested the ma-ternal tail suspension test ( TST). Both YG and Ket-amine was single administered 24 hours before behavior test, with single saline for control group and PPD mod-el group. After TST,the mouse hippocampus were ex-tracted to detect the expression of AKT and mTOR. Results After 3 weeks postpartum, the model mice showed depression-like behaviors. Immobility in TST was significantly increased in vehicle groups(P <0. 01). Acute YG improved performance in the TST (P< 0. 01), which was similar to ketamine. And the PPD model mice group showed decreased phosphorylation of AKT and mTOR (P < 0. 01,P < 0. 01), compared to control group. A single dose of YG or ketamine normal-ized AKT/ mTOR signaling in the PPD model mice(P< 0. 01,P < 0. 01),( P < 0. 01,P < 0. 01). Conclu-sions Chronic pre-pregnancy stress can induce dams into postpartum depression and its mechanism maybe associated with down-regulating AKT/ mTOR signa-ling. Acute YG exerts fast antidepressant effect on this PPD model similar to ketamine, and its mechanism may be related to up-regulating AKT/ mTOR signaling in the hippocampus.

Aim To establish a postpartum depression animal model,assess the abnormal maternal behaviors of depressive dams,and observe the rapid antidepres-sant effects of the Yuejuganmaidazaotang (YG)on the PPD model.Methods Thirty-two female Balb /c were randomly assigned to two groups,the control group (Control,con)and the pre-pregnancy stressed group (Vehicle,veh),and vehicle was subjected to 3 weeks chronic restraint stress.After the last stressor,the pre-pregnancy stressed group was housed with a male.Af-ter about 4 weeks later,the mice gave birth to pups. Then at 3 weeks postpartum,we tested the maternal depressive-like behaviors,including sucrose preference test,forced swimming test and novelty suppressed feeding test.Both YG and Ketamine were single ad-ministered 24 hours before behavior test,with single saline for control group and PPD model group.Results After 3 weeks postpartum,the vehicle mice showed depression-like behaviors.Reduced preference in drinking sucrose solution was found in SPT (P <0.01 ).Immobility in FST was significantly increased in vehicle groups (P <0.01 ).In NSFT,the vehicle group displayed a significantly increased latency and reduced unit of food intake compared with control group(P <0.01,P <0.01 ).Acute YG improved per-formance in the SPT(P <0.01),FST (P <0.01)and NSF (P <0.01,P <0.01),which was similar to ket-amine.Conclusions Chronic pre-pregnancy stress can induce dams into postpartum depression.Acute YG exert fast antidepressant effect on this PPD model simi-lar to ketamine.
RESUMO
Abstact:Aim To identify whether the petroleum e-ther fraction of Yueju pill (YJ-PE)could exhibit a po-tent rapid antidepressant effect and to investigate the underlying biological mechanism involved.Methods Fourty-four male KM mice were randomly assigned to five groups:the control group (saline group),low dosage of YJ-PE,middle dosage of YJ-PE,high dos-age of YJ-PE and ketamine.After a single drug admin-istration,we used tail suspension test (TST)to test the rapid antidepressant effect of YJ-PE in KMmice at 30 min.Another twenty-four male KM mice were ass-inged to three groups:control group,screened effective low dosage of YJ-PE group and ketamine group.We usd TST to assess these mice at 24 h post a single ad- ministration.Western blot was performed to examine the expression of BDNF and TrkB in hippocampus of KMmice at 30 min and 24 h post a single administra-tion.Results An acute administration of YJ-PE de-creased the immobility time of KMmice in TST and in-creased the expression of BDNF and TrkB as soon as 30min post a single administration and lasted at least for 24 hours.Conclusion YJ-PE (low dosage)ex-hibits a rapid antidepressant-like potent,and the po-tent rapid antidepressant effects of YJ-PE are associat-ed with the up-regulation of BDNF and TrkB.
RESUMO
OBJECTIVE: To analyze the effects of social and psychological factors on rehabilitation status of end stage renal disease (ESRD) patients under peritoneal dialysis. METHODS: From August in 2005 to March in 2007, 171 patients experienced peritoneal dialysis were diagnosed at the Center of Peritoneal Dialysis, Department of Nephrology, First Hospital, Peking University, including 66 males and 105 females, aged (60±13) years, with an average dialysis time of 22.8 months. They were studied with questionnaires and interview. Rehabilitation status was investigated from two aspects of activity and participation by Karnofsky activity index, Social Dysfunction Screening Scale. Hamilton depression and anxiety scales, Medical Coping Modes Questionnaire and Social Supporting Rating Scale were used to investigate social and psychological factors.RESULTS: A total of 200 questionnaires were handed out and 171 (85.5%) of them were drawn in. 134 patient had normal activity status, 78.4% of them had Dysfunction and 129 patients (75.4%) had normal social function status. Forty-two (24.5%) of patients had the symptom of anxiety, 15 (8.2%) had depression. The score of "Acceptance-Resignation" was significantly higher in this group than patients with other chronic diseases. There were no significant differences in scores of "Confrontation" and "Avoidance". Activity of rehabilitation outcome and participation index served as dependent variable, whereas depression and anxiety, coping mode and social supporting as independent variable. Using multiple stepwise regression analysis, factors that affected patient rehabilitation were found, including depression, utilization of social support and the facing coping mode. CONCLUSION: Depression, utilization of social support and the facing coping mode have important effects on patient rehabilitation.
