Objective To explore the relative importance of factors of sleep quality in predicting the anxiety and depression emotion. Methods Sleep quality and emotional condition of 112 patients with coronary heart disease were investigated with Pittsburgh sleep quality index(PSQI), self-rating anxiety scale (SAS)and self-rating depression scale (SDS). The relation between sleep quality and emotional condition was analyzed deeply by dominance regression analysis. Results After controlling the demographic vari-able of the sex,factors of the sleep quality such as sleep efficiency and function in the daytime had predict-ing effect on depression emotion;factors such as function in the daytime, sleep quality, sleep efficiency and sleep time possessed predicting effect on anxiety emotion. Conclusions According to different contribu-tion of various factors of sleep quality to anxiety and depression emotion, we should implement selective medical and nursing intervention during clinical work.

Objective Based on active monitoring MRSA carriage for hospitalized patients, the relationship between colonization pressure and MRSA cross transmission in wards without rigorous contactisolation measures was analyzed, and the role of colonization pressure in predicting MRSA cross transmission was further evaluated. Methods From March to December 2009, active MRSA colonization screening was performed for 240 hospitalized patients in emergency ward and 94 cases in RICU in our hospital. rep-PCR method was employed to do homology analysis on MRSA strains obtained in this study. MRSA weekly colonization pressure, threshold colonization pressure ,cross transmission rate were calculated respectively. RR of MRSA cross transmission under higher level of colonization pressure and lower level of colonization pressure was analyzed. Results MRSA carriage rates on admission for patients in emergency wards and RICU were 6. 25% (15/2A0) and 13. 83 % (13/94) ,and MRSA cross transmission occurred in 13 weeks and 14 weeks in above two units, respectively. Threshold colonization pressures for above two units were 6. 49%and 17. 66%, respectively. For emergency ward, the MRSA cross transmission rate under higher level of colonization pressure was significantly higher than that under lower level of colonization pressure (x2 = 7. 10,P＜0. 01), the RR of MRSA transmission was 9. 61 (95% CI:1. 25-74.00). For RICU, the MRSA cross transmission rate under higher level of colonization pressure was significantly higher than that under lower level of colonization pressure(x2 = 12. 60, P＜0. 01 ), the RR of MRSA transmission was 15.87 (95% CI:2. 06-122. 10). Conclusions Higher level of colonization pressure is an important risk factor for MRSA transmission, and average colonization pressure can be used as a prediction index for MRSA transmission and strengthening prevention and control measures.

Aim To explore the effect of pharmacolog-ical activation of serotonin 5-HT2C receptor (5-HT2C R) on naloxone-precipitated withdrawal in morphine-de-pendent mice. Method EthoVision Noldus video tracking system was used to record the effect of 5-HT2C R agonist WAY on locomotor activities and behavioral performances in mice.Results Selective 5-HT2C R ag-onist WAY (0.5,0.75 or 1 .0 mg·kg -1 ,i.p.)a-lone did not alter the locomotor activities as determined by distance traveled and velocity (all P values >0.05).Chronic morphine treatment induced depend-ence in mice as demonstrated by increases in distance traveled,velocity and jumping behavior.WAY (0.5, 0.75 or 1 .0 mg·kg -1 ,i.p.)and clonidine (0.2 mg ·kg -1 ,i.p.)significantly ameliorated naloxone-pre-cipitated withdrawal symptoms,including burrowing, jumping,body grooming,rearing,“wet dog”shakes, head shakes,face grooming,penile grooming,scratch (all P values <0.05).Conclusion Pharmacological activation of 5-HT2C R ameliorates naloxone-precipitated withdrawal symptoms in morphine-dependent mice.5-HT2C R may be a novel target to develop therapeutic ap-proach against morphine physical dependence,craving and relapsing.

Aim To study the apoptotic inducing effects of deguelin on SH-SY5Y cells.Methods SH-SY5Y cells were treated with 0,0.625,1.25,2.5,5,10 and 20 μmol·L-1 deguelin for different time(24,48,72 h);cell viability was detected by CCK-8 assay.SH-SY5Y cells were treated with 0,8,20,50 μmol·L-1 deguelin for 24 h;light microscope and AO/EB double stained method were employed for observing the morphology and apoptotic morphology of treated cells.Apoptotic rate of treated cells was determined by flow cytometry.Cells were stained by DCFH-DA,and the whole reactive oxygen species(ROS)was determined by flow cytometry.Spectrophotometry was employed to determine the activation degree of caspase-3.Results Deguelin inhibited cell growth in a time-and dose-dependent manner,and the IC50 value of deguelin was(26.07±2.18),(18.33±0.94),(12.5±1.49)μmol·L-1 when treated with 24,48,72 h respectively.After treated with 8,20,50 μmol·L-1 deguelin for 24 h,cell apoptotic rate,ROS and activation rate of caspase-3 increased markedly(P<0.05),all of which performed a dose related effect.Conclusion Deguelin can inhibit SH-SY5Y cell proliferation and induce cell apoptosis,and the mechanism may be concerned with the elevated ROS and activated caspase-3.

Objective The experiment was designed to study the therapeutic mechanism of "Tong Tiao" acupuncture in the treatment of mammary gland hyperplasia (MGH) on the rat model.Methods A total of 75 healthy unpregnant female SD rats were randomly divided into six groups: blank, model, control group, vagus cutting therapy, sham operation, and vagus cutting with non-treatment group. All the groups except the blank group were prepared by MGH rat model. The vagus cutting therapy and vagus cutting with non-treatment group were treated by cutting the right cervical vagus nerve, while the sham operation group was treated by exposing the vagus nerve without any operation. All the treatment groups were treated with "Tong Tiao". The rat papillary height was measured. The breast tissue morphology and breast ultrastructure were observated. And the flow cytometry in rat peripheral blood T lymphocyte subsets CD3+, CD4+, CD8+, CD4+/CD8+ were calculated. Results Compared with the model group, the papillary height (1.22 mm ± 0.21 mm,1.24 mm ± 0.20 mmvs. 1.53 mm ± 0.16 mm) in the normal treatment and the sham treatment group decreased significantly the vagus cutting therapy and vagus cutting non-treatment group showed no difference (P>0.05). Compared with the model group, the Mammary gland morphology and ultrastructure in the normal treatment group, the sham operation group and the vagus cutting therapy groups were improved, but the vagus cutting non-treatment group showed on improvement. Compared with model group, the serum CD3+(61.5％ ± 10.5％, 61.1％ ± 12.4％, 59.8％ ± 11.8％vs. 57.7％ ± 9.4％), CD4+(37.2％ ± 8.9％, 37.9％ ± 10.9％, 36.1％ ± 12.2％ vs. 34.6％ ± 6.9％), CD4+/CD8+(1.59 ± 0.8, 1.58 ± 0.8, 1.38 ± 0.6vs. 1.23 ± 0.7) in the normal treatment group, the sham treatment group and vagus cutting therapy group, elevated significantly (P<0.01,P<0.05), while the vagus cutting non-treatment group showed no difference (P>0.05). Compared with model group, the serum CD8+ (24.2％ ± 11.3％, 24.5％ ± 10.6％,25.5％ ± 8.8％vs. 27.7％ ± 9.9％) in the normal treatment group, sham treatment group and vagus cutting therapy group decreased significantly lower (P<0.01,P<0.05), but vagus cutting non treatment group showed no difference (P>0.05). Conclusions the mechanism of acupuncture treatment for MGH may be related to the vagus nerve by regulating the CD3+, CD4+, CD8+ and CD4+/CD8+ levels of T lymphocytes.
