Objective To investigate the influence on the behavior of withdrawal and relapse after deep brain stimulation of bilateral nucleus accumbens in morphine-dependent rats. Methods The rats with a strong unconditioned preference were discarded in preconditioning test, the selected rats were distributed into five groups randomly. After operation,morphine hydrochloride was injected subcutaneously into SD rats for 12 days (once every day,initial 5 mg/kg,increasing by 5 mg/kg per time,stable in 20 mg/kg ). A modified electrical circuit was used to procedure the DBS,the parameter was 130 Hz,150 A,60 s,l h/d,14 d. CPP test was used to exam the effect of DBS. A minor morphine dose (3 mg/kg) was injected to induce the behavior of relapse, and CPP was tested again after 24 h. Two-way ANOVA was performed on the data with Bonferroni posttest. Result ①After CPP training,CPP score of group morphine, morphine + sham and morphine + DBS was ( 155. 87 ± 20. 45 ) s, (107.33 ± 18.10)s,(135.45 ±22.09)s,and had significant difference with group of control( ( -70.34 ± 15.40) s)(t = 9.45,P<0.01; t = 6.94,P<0.01;t = 8.04,P<0.01).②After 7 days' DBS,the CPP score in group of morphine + DBS reduced significantly compared to group of morphine( t = 4.21, P<0.01) and morphine + sham( t=1.10, P<0.05).0n the 14th day,there was more pronounced reduction ( t = 5. 15, P<0.01; t = 3.92, P< 0.01). ③ 24 hours after the minor morphine dose was injected,the CPP score in morphine + DBS didn't increase significantly, and had significant difference with group of morphine ( t = 4.04, P<0.01) and morphine + sham ( t= 4. 13, P<0.01). Conclusion DBS bilateral nucleus accumbens in morphine-dependent rats can interfere the behavior of morphine-induced CPP and relapse.

Objective This study is to discuss the effects of cognitive therapy on life quality of rural breast cancer patients during chemotherapy in order to offer evidence for choosing the appropriate therapeutic measures.Methods 120 rural breast cancer patients were equally divided into the intervention group and the control group at random.The usual care plus cognitive treatment was given to the patients in the intervention group for 6 months,while only the usual care after chemotherapy was given to the control group.The quality of life assessments were carried out to both groups on the 5th day during hospitalization,and the first,third and 6th month during recheck period of time,respectively.The treatment effect was observed.Results There were statistical significant difference of the total scire of life quality assessment on the 5th day,the first,third and 6th month,respectively,between the intervention group and the control one after cognitive intervention.The downtrend of total score of quality of life in the intervention group after cognitive intervention was more significant than the control group,which indicated the quality of life of the intervention group was better than the control group. Conclusions Cognitive therapy is an efficient method to enhance the quality of life of rural breast cancer patients during chemotherapy.

AIM:To compare the reliability and plaque area between using high-cholesterol diet and high-cho-lesterol diet with corn oil to establish a rabbit atherosclerotic model .METHODS:Eighteen New Zealand rabbits were ran-domly divided into 3 groups (6 rabbits each):normal diet group (group C), high-cholesterol diet group (group H1) and high-cholesterol diet containing 6%corn oil group (group H2).All rabbits were fed for 12 weeks, and their body mea-sured was weighed at the end of every weeks .The serum levels of high-density lipoprotein cholesterol ( HDL-C) , low-den-sity lipoprotein cholesterol ( LDL-C) , total cholesterol ( TC) and triglyceride ( TG) were measured by automatic chemistry analyzer at 0 week and 12 weeks.At the end of 12 weeks, the thoracic aorta of 8-cm length since aortic root was isolated from the rabbit after anesthesia , and stained with Sudan IV or oil red O to verify the existence of plaque .The percentage of plaque area (PA/IA) in the intima area was further calculated by ImageJ 2x software.RESULTS:At the end of 12-week feeding, the serum levels of HDL-C, LDL-C and TC in both group H1 and group H2 were significantly higher than those in group C, and serum TG in group H2 was significantly higher than that in group C .Serum HDL-C in group H2 was signifi-cantly higher than that in group H1, but no significant difference of serum LDL-C, TC and TG between group H1 and group H2 was found .There was no plaque in the intima in group C , and plaques were observed in the intima of all rabbits in group H1 and group H2.Rabbit atherosclerotic models in both group H 1 and group H2 were established with a success rate of 100%.The values of PA/IA in group H1 [(49.74 ±18.78)%] and group H2 [(56.95 ±26.74)%] were both sig-nificantly higher than that in group C (0%), and no significant difference of PA/IA between group H1 and group H2 was observed.CONCLUSION:High-cholesterol diet with or without corn oil can establish a rabbit atherosclerotic model with a success rate of 100%after 12-week feeding , and the percentage of plaque area in the total aortic intimal area is not differ-ent in the 2 feeding methods .

Aim To observe the protective effect of quercetin on rat cardiomyocyte apoptosis induced by adriamycin and explore its possible mechanism.Methods Cultured neonatal rat cardiomyocytes were randomly divided into six groups:normal control group, adriamycin group,quercetin control group, adriamycin+quercetin(25,50,100 ?mol?L-1)groups. The activity of LDH was detected by chromatometry, the cardiomyocyte viability was measured by MTT, the ultrastructure of cardiomyocyte was observed by electron microscope, the expression of protein Bcl-2 and Bax was analyzed by immunocytochemical, and the mRNA and protein of caspase-3 were detected by RT-PCR and Western blot respectively.Results Compared with the control group, the activity of LDH was increased but the viability of cardiomyocyte was decreased; the expression of Bax and caspase-3 was up-regulated while Bcl-2 was down-regulated in ADR group.Compared with ADR group, the above changes were lightened in adriamycin+quercetin groups. But the quercetin control group, in which cultured myocardial cells only exposed to quercetin without ADR, had no obvious changes.Conclusions Quercetin significantly inhibits the apoptosis induced by ADR in the cultured myocardial cells. Its mechanism is involved in the apoptosis-related pathways, including caspase-3, Bax and Bcl-2.

OBJECTIVETo investigate the cardiac effect of QT interval prolongation in the treatment of acute promyelocytic leukemia (APL) with arsenic trioxide (As(2)O(3)), and the relationship between QT and serum arsenic concentration.
METHODSBlood serum arsenic concentrations of thirty APL patients were determined at 2 hours, 4 hours, 8 hours, and 24 hours after As(2)O(3) injection using atomic fluorophotometry. Cardiac functions were measured simultaneously using a 12-lead body-surface electrocardiogram (ECG). Q-T intervals were manually measured, and then corrected using Bazett's formula (QTc). QT dispersion (QTd) was also calculated. In order to assess the effects of arsenic on the symptoms of anemia, twenty-four anemia patients were divided into two groups on the basis hemoglobin concentration: Group 1 (Hb > or = 90 g/L), and Group 2 (60 g/L < or = Hb < 90 g/L). QTc and QTd of these patients were also manually measured.
RESULTSAll QT intervals of APL patients treated with As(2)O(3) injection were prolonged [32.2 ms (27, 41 ms); P < 0.05], but the changes of QTd were not prominent [3 ms (-8, 7 ms), P > 0.05]. There was a delay of 2 hours in maximum QTc following peaks in serum arsenic concentration. Changes in QTc and QTd of the two anemic groups were not prominent.
CONCLUSIONSAs(2)O(3) can prolong QTc intervals in APL patients, but the effects are delayed compared to peak serum arsenic concentrations. As(2)O(3) has no prolongation effect on QTd. Mild and moderate anemia do not effect QTc and QTd.
