ABSTRACT
Objective To analyze the effects of curcumin combined with cisplatin on the growth and lymphatic metastasis of cervical cancer xenografts in nude mice.Methods The human cervical carcinoma Caski cells xenotransplanted tumor models were established.Inoculated mice were randomly divided into 4 groups according to random number table:control (normal saline 10 ml/kg),Cur (curcumin 100 mg/kg),Cis (cisplatin 3 mg/kg) and Cur + Cis group (100 mg/kg curcumin +3 mg/kg cisplatin).The tumor volume and anti-tumor rate were calculated.The mRNA levels of macrophage migration inhibitory factor (MIF) and vascular endothelial growth factor-C (VEGF-C) were analyzed by real-time fluorescent quantitative polymerase chain reaction (PCR).Results The inhibitory rates of Cur group,Cis group and Cur + Cis group were 40.8％,53.3％ and 60.0％.After 15 days treatment,the tumor volumes of the control group,Cur group,Cis group and Cur + Cis group were (123.44 ± 35.62),(71.72 ± 28.36),(65.47 ± 18.32),(53.44 ± 10.79) mm3.The growth rates of tumor volume in Cur group,Cis group and Cur + Cis group were slower,Cur + Cis group could more effectively inhibit tumor volume growth.The difference among the four groups had statistically significance (F =16.890,P =0.000).Real-time fluorescent quantitative PCR detection showed that compared with the control group (1.000),the MIF mRNA expressions in Cur group,Cis group and Cur + Cis group were 0.322 ±0.094,0.154 ± 0.006 and 0.136 ± 0.007,VEGF-C mRNA expressions in the three groups were 0.312 ± 0.068,0.263 ± 0.072 and 0.221 ± 0.041.The differences among groups had statistically significance (F =220.279,P =0.000;F =143.250,P =0.000).MIF mRNA was positively related with VEGF-C mRNA (r =0.815,P =0.001).Conclusion Curcumin combined with cisplatin can inhibit the growth of Carski cell xenografts in nude mice.Through the down-regulating expression of MIF mRNA and VEGF-C mRNA,cisplatin and curcumin can inhibit the lymphatic metastasis of cervical cancer,and it may be one of the important mechanisms of its anti-tumor effects.
ABSTRACT
Objective To assess the mental health status of the pregnant women with missed abor-tion, as well as related influencing factors, and to provide the basis for mental nursing. Methods 100 pregnant women with missed abortion were chosen as the observation group by convenience sampling, while other 100 normal pregnant women as the control group. The mental state of the pregnant women in both groups was evaluated by using symptom checklist-90 (SCL-90), the results of which were then studied in contrast using t test and variance analysis. Results The total scores and the average scores of pregnant women in the observation group were significantly higher than those in the control group. The mental health status of pregnant women with missed abortion was influenced by age, education degree, and the times of pregnancy. Conclusions There are significant mental health problems in pregnant women with missed abortion, to which should be paid much attention. And the psychological counseling should be carried out in time in case of detrimental influences in treatment, rehabilitation, and next pregnancy.
