AIM:To compare the effect of 1,2-propanediol (PROH) and ethylene glycol (EG) on apoptosis and expressions of P53,Bcl-2 of follicles in human ovarian tissue,in order to offer experimental foundation for selecting the best cryoprotectant. METHODS:Biopsies of ovarian tissue obtained from 12 women were cryopreserved,and ovarian tissue slice from each woman was divided into three groups:fresh control group,ethylene glycol group and 1,2-propanediol group. The slow-freezing /rapid-thawing protocol was used to freeze and thaw the slice of ovarian cortex. Apoptosis of follicles in fresh and frozen-thawed ovarian cortical tissue was detected by TUNEL experiment,and expressions of P53 and Bcl-2 were detected by immuno-histochemistry. RESULTS:The percentages of apoptosis follicles were 14.58%,23.08%,30.43% in fresh control group,PROH group and EG group,respectively,and the percentage of apoptosis follicles in EG group was higher than that in fresh control group (P0.05). The percentages of P53 positive follicles were 13.48%,25.00% and 33.93%,respectively. There was significant difference between fresh control and EG group (P0.05). CONCLUSION:The results of this study indicate that 1.5 mol/L PROH is more suitable for cryopreservation of human ovarian tissue rather than 1.5 mol/L EG in slow-freezing /rapid-thawing protocol. The protocol of slow-freezing/ rapid-thawing may preserve oocytes well,but it is not ideal for cryopreservation of granulosa cells. Cryopreservation may influence on apoptosis of follicles in human ovarian tissue.

To improve the solubility of quercetin ( QT) , one of flavonoids that can inhibit the proliferation of vari-ous types of cancer cells, the novel amphiphilic polymer N-( 4-methylimidazole)-hydroxyethyl-chitosan ( MHC) , synthetized by chemical derivatization from chitosan, was used as the self-assembly micelles of QT. The formed polymer was characterized by 1 H NMR, elemental analysis and pyrene fluorescence spectrometry. The formulation of MHC micelles loading quercetin was optimized through single factor experiment. Then the optimized formulation was obtained as follows:the concentration of MHC was 0. 67% and the ratio of drug and carrier was 1 ∶10. The micelles particle size was ( 99. 21 ± 1. 71) nm, Zeta potential was +( 20. 01 ± 0. 72) mV and drug loading was ( 5. 42 ± 0. 32 )%. The in vitro release curve was investigated and was found to conform to Higuchi equation of Q=0. 1101 t1/2 -0. 064. The results of in vivo experiment showed that the mean rentention time and bioavail-ability of the MHC-QT micelles were 21. 42 h and 57. 49 μg h/mL, respectively, compared to 0. 30 h and 2. 50 μg h/mL of the free QT solution. These indicated that the MHC micelles could significantly improve the solubility of QT, the drug sustained-release effect and bioavailability, which would used as carrier for the anti-tumor drugs.
