Objective To investigate the effects of antisense oligodeoxynucleotide c-myc (c-myc ASODN) on the growth of rabbit lens epithelial cells (LECs) induced by galactose. Methods Based on the translation initiation region of the second extron of c-myc gene, oligonucleotides were synthesized and modified with phosphorothioate. Lens epithelial cells were treated with galactose and c-myc ASODN. The effects of c-myc ASODN on the growth of LECs, cultured in high concentration of galactose, were observed by cytometry and MTT. Results The results demonstrated that c-myc ASODN at the doses of 2.5-10.0 ?mol/L inhibited the growth of LECs induced by galactose in a dose-dependent manner. Conclusion These results indicate that c-myc ASODN can inhibit the growth of LEC induced by galactose.

Objective To investigate the clinical efficacy of bromhidrosis with botulinum toxin A by needle free injection.Methods A total of 40 patients with bromhidrosis were collected and divided into needle free group and needle group.A comparative study was carried out in those subjects.Patients in needle free group received needle free injection of botulinum toxin A by INJEX30;Needle group received traditional injection by 26 G needles.Results In needle free group,16 cases were cured,3 cases were effective,1 case was ineffective,no significant pain,hematomas or necrosis were found.In needle group,15 cases were cured,4 cases were effective,and 1 case was ineffective;localized hematoma occurred in 2 cases.And cases in group needle experienced pain more intensely than cases in needle free group.Conclusions The INJEX30 improves the security,comfort and therapy compliance of botulinum toxin A injection in the bromhidrosis patients,with similar efficacy with traditional injection.

The main objective of this research is to investigate the effects of astragaloside IV, calycosin separately glucoside, formononetin on oxidative stress in Chang Liver cells induced by H2O2. In the experiments, Chang Liver cells (a kind of normal human hepatocytes) were used as the research object, bifendate which has a clear hepatoprotective effect was used as the positive control drug, then the oxidative damage model of Chang Liver cells were established by H2O2. Cells were divided into six groups: blank control group, oxidative stress group, astragaloside IV group, calycosin separately glucoside group, formononetin group and positive control group. Then endogenous antioxidant system related indexes were detected by micro plate and colorimetric method; intracellular reactive oxygen species (ROS) were detected by DCFH-DA fluorescent probe; and the expressions of CYP2E1 were evaluated by liver microsomes, mRNA, and protein, respectively with spectrophotometry, Real-time PCR method, and Western blot technique. Results showed that H2O2 decreased antioxidant activity, and increased ROS level and expression of CYP2E1. The above oxidative stress status had been changed with protections of the three components of Astragalus membranaceus (compared with oxidative stress group, P < 0.05, P < 0.01), which taken as a whole had equivalent effects as the drug of positive control group( bifendate). Taken together, three Astragalus membranaceus ingredients all had significant or extremely significant inhibiting effects on oxidative damaged Chang Liver cells which were induced by H2O2, and the oxidative damage of Chang Liver cells had been relieved.

OBJECTIVETo explore various factors affecting the clinical pregnancy outcomes of artificial insemination with donor sperm (AID).

METHODSWe retrospectively analyzed 15,744 cycles of AID in 6302 women and investigated the association of the clinical pregnancy outcomes of AID with the treatment protocols, the times of insemination per cycle, the age of the infertile women, the status of the oviduct, and the number of AID cycles.

RESULTSThe pregnancy rate of AID was higher in the chlomiphene-treated women than in those of the natural cycle group (P = 0.003) but showed no significant differences either between the chloramiphene and human menopause gonadotropin (HMG) or between the HMG and natural cycle groups (P > 0.05), and so was it in the women that had received AID twice per cycle before and after ovulation (26.3%) than in those that had undergone only once before (7.0%) or after ovulation (23.7%) (P < 0.05). However, the pregnancy rate was remarkably lower in the women aged 35-40 years (16.5%), especially in those over 40 years (1.2%), than in those under 35 years (26.0%) (P < 0.05). There was no significant difference in the success rate of AID between the women with oviductal adhesion and those without (27.4% vs. 28.1%, P > 0.05). The pregnancy rate of the first cycle of AID (27.6%) was markedly higher than those of the second (24.7%), third (23.9%), and fourth (23.1%) (P < 0.01), but with no significant differences among the latter three cycles (P > 0.05), while that of the fifth cycle (19.0%) was remarkably lower than those of the first four (P < 0.01).

CONCLUSIONThe age of the infertile women is an important factor affecting the success rate of AID. AID twice per cycle is better than once only. For those without oviductal factors, at least 4 cycles of AID are required before in vitro fertilization.
