Objective To observe the effects of mirtazapine to improve the life quality of malignant tumor patients with moderate or severe depres-sion. Methods Patients with mood disorders screened by the physician were then graded by the Hamilton Depression Scale(HAMD)under the tu-telage of ward psychological consultant. Fifty patients with moderate or severe depression were selected by psychological doctors and recruited for the study. After obtaining consent,the patients received 15-60 mg/d mirtazapine every night for 9 weeks. According to the Quality of Life Rating Scale (QOL),the scores of these patients were evaluated at the pretreatment,the 3rd week and the 9th week of the post-treatment. Then,the life quality conditions before and after treatment were revaluated. Results The scores of HAMD were 33.16±7.25,28.74±6.24,and 22.58±6.71 at the pretreat-ment,the 3rd week and the 9th week of the post-treatment,respectively. There were significantly different among the HAMD scores at the pretreat-ment,the 3rd week and the 9th week of the post-treatment.(F=30.99,P<0.01). The scores of HAMD were improved significantly between the pre-treatment and the 3rd week of the post-treatment(P<0.05). The scores of HAMD were also improved significantly between the 3rd week and the 9th week of the post-treatment(P<0.05). After treatment by mirtazapine,the appetite,spirit,sleep,fatigue,pain,the reorganization of cancer,the attitude towards treatment,the side effect of treatment and the facial expression were significantly improved(P<0.01). Conclusion Mirtazapine could improve the life quality of malignant tumor patients with moderate or severe depression.

OBJECTIVE:To explore the effects of Haikangling Mixture on immunological function in immunosuppressed mice induced by cyclophosphamide. METHODS: Mice were given Haikangling Mixture intragastrically for 14d, and the level of hemolysin was determined by sheep erythrocyte (SRBC) immunization to exploer the influence of Haikangling on humoral immunity in mice; splenic lymphocytes were measured by MTT to observe the influence on cell immunity; the clearance of macrophage were measured by carbon particle clearance method to explore the influence on non-specificity immunity. RESULTS: The level of hemolysin, the cell reproductive activity, splenic lymphocytes and the phagotrophy of mononuclear macrophage were improved obviously by Haikangling Mixture in immunosuppressed mice induced by cyclophosphamide. CONCLUSION: Haikangling Mixture can enhance the immunological function in immunosuppressed mice induced by cyclophosphamide.

Objective To evaluate the prognostic factors of elderly patients with noscomial Candidemia in intensive care unit. Methods A retrospective study was carried out in 75 elderly patients with noscomial Candidemia from 2001 to 2008. Multivariate logistic regression analysis was performed to find the correlations of prognosis with clinical and biochemical parameters. Results A total of 75 Candida strains were isolated from blood. The proportion of non-albicans species reached to 70.7%. Fluconazole-resistant candidiasis was increased. Overall mortality rate was 48.0%.Multivariate logistic regression analysis showed that septic shock, comorbid bacteremia, higher serum creatinine and sequential organ failure assessment (SOFA) score more than 10 were independent predictors for in-hospital mortality (Ward=6.34, 5.15, 8.04, 6.82, all P＞0.05). Conclusions Noscomical Candidemia in elderly critical illness patients leads a high mortality, the proportion of nonalbicans species and fluconazole-resistant candidiasis increase. The blood culture and drug sensitive test should be performed routinely to provide proper evidence for antifungal therapy. Monitoring the high risk factors, effective and reasonable therapeutics are the guarantee for reducing the mortality induced by Candidemia.

Objective To evaluate effects of different laparoscopic procedures for hydrosalpinx on ovarian responses to superovulation induction during in vitro fertilization-embryo transfer(IVF-ET).Methods A total of 65 patients with infertility derived from hydrosalpinx underwent 67 cycles of IVF-ET from January 2002 to January 2005.Before the IVF-ET,the patients were given bilateral laparosocpic salpingectomy(Group A,n=47,48 cycles) or laparosocpic proximal tubal ligation and distal tubal salpingostomy(Group B,n=18,19 cycles).Another 58 patients with proximal tubal occlusion without hydrosalpinx were simultaneously included for 58 cycles of IVF-ET(Group C).Results The fertilization rates,cleavage rates,implantation rates,and clinical pregnancy rates were 85%?21%,95%?17%,49%(55/113),and 79%(38/48) in the Group A,83%?17%,98%?7%,47%(21/45),and 68%(13/19) in the Group B,and 81%?22%,92%?16%,41%(57/140),and 66%(38/58) in the Group C,respectively,without statistically significant difference among the 3 groups(F=0.48,P=0.620;F=1.22,(P=0.297);?~2=1.691,P=0.429;?~2=2.471,P=0.291).The doses of gonadotrophin,the duration of stimulation,and the number of retrieved oocytes were 29.4?10.3 vials,9.4?1.7 d,and 11.4?5.6 in the Group A,24.7?7.7 vials,9.0?1.8 d,and 12.8?6.1 in the Group B,and 28.4?8.8 vials,9.1?1.8 d,and 11.4?5.3 in the Group C,respectively,without statistically significant difference among the 3 groups(F=1.77,P=0.174;F=0.52,P=0.593;F=0.51,P=0.599).Conclusions Laparosocpic salpingectomy or laparosocpic proximal tubal ligation with distal tubal salpingostomy for hydrosalpinx does not impair ovarian responses to the superovulation induction.Both of the procedures may be considered for the treatment of hydrosalpinx prior to IVF-ET.
