Effect of Xiaoyao pill combined with low-dose corticosteroid on serum estrogens in menopause syndrome and its clinical efficacy / 中国生化药物杂志

Objective To explore the effect of Xiaoyao pill combined with low-dose corticosteroid on serum estrogens levels in the treatment of patients with menopause syndrome and its clinical efficacy.Methods 96 patients with menopause syndrome from April 2013 to February 2015 in department of obstetrics and gynecology of Lishui second people’s hospital were selected and divided into 2 groups according to a random number table, the control group (48 cases) were treated with small dose of hormone therapy, the treatment group (48 cases) were treated with Xiaoyao pill combined with small dose of hormone therapy.The serum estrogens levels, Kupperman score, endometrial thickness and clinical efficacy were compared. Results The total effective rate of control group(79.17%) was lower than that of treatment group(93.75%)(P<0.05).Compared with control group post-treatment, the serum follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels were lower, estradiol (E2) level was higher, the Kupperman score was lower, the endometrial thickness was higher than those of control group, there were significant differences ( P <0.05 ) . Conclusion Xiaoyao pill combined with small dose of hormone could improve serum E2, FSH and LH levels in the treatment of patients with menopause syndrome with high security.

The speciifc inhibition of siRNAs targeting 5' untranslated region of the enterovirus 71 genome / 临床儿科杂志

Objective To screen and identify effective small interfering RNA (siRNAs) targeting the conserved 5’ untrans-lated region (UTR) of the enterovirus 71 (EV71) genome. Methods Double-stranded siRNAs were designed to target the 5’UTR of the EV71 genome. The cytotoxicity effect of siRNAs on rhabdomyosarcoma (RD) cells was evaluated. The cytopathic effect on EV71-infected RD cells was observed under phase-contrast microscopy and the effective siRNAs were screened out by cell viability assay and real-time TaqMan RT-PCR assay. Results All the siRNAs did not exhibit any cytotoxic effects on the viability and growth of RD cells. Transfection of si-1 and si-2 targeting the 5’ UTR in EV71 genome into RD cells signiifcantly delayed and alleviated the cytopathic effects of EV71 infection, increased cell viability and reduced the EV71 RNA transcripts. And the inhibitory effect of si-1/si-2 on EV71 replication was sequence-speciifc. Conclusions The 2 siRNAs (si-1 and si-2) targeting the conserved 5’UTR of the EV71 genome may have broad spectrum antiviral effects on many epidemic EV71 strains.
