Young women affected by education and career delay the childbearing period,which results in reduced fertility.With the two-child policy completely opening,more and more elderly women have demands for pregnancy and the need of assisted reproductive technology (ART) increases day by day.However,the ART treatment faces with a series of medical and ethical problems.For example,the pregnancy rate of aged women is low but the abortion rate is high;and the incidence of pregnancy complications and fetal chromosomal abnormality increases significantly.In this regard,it can solve these problems through limiting the women's age,choosing the donated eggs,strengthening the counseling for elderly infertile women before ART treatment,paying attention to the psychological problems and applying the genetic screening technology before implantation.

Objective To explore the method and effect of computer simulative model of lying-in women in the teaching of gynecological nursing. Methods We separated 171 nursing students in grade 2005 into the control group (85 students) and the experimental group (86 students). For the experimental group the teaching method of computer simulative model of lying-in women was used. For the control group we used the traditional teaching method. The effects of two teaching methods were compared. Results The examination achievement of the experimental group was more than that of the control group and 93% nursing students of grade 2005 approbated this teaching method. Conclusions Introducing computer simulative model of lying-in women into the teaching of gynecological nursing can not only improve the effect of teaching, stimulate studying interest and cultivate unity and cooperation ability.

OBJECTIVE:To study antioxidant activities of ethanol extract of Paeonia lactiflora (CREt) and different polar parts in vitro. METHODS:CREt was prepared with 95% ethanol. CREt (extracted by 50% ethanal) was extracted with aether petrolei,acetic ether and n-butyl alcohol to obtain aether petrolei part (CRP part),acetic ether part (CRE part),n-butyl alcohol part(CRB part)and water part(CRW part). The ability of CREt and different polar parts eliminating DPPH·,O2-· and ·OH were investigated (mass concentrations of CREt and different polar parts were respectively 0.75-12,0.5-6,1.25-15 mg/ml in above 3 tests) and compared with ascorbic acid (VC,0.2 mg/ml) group. RESULTS:The maximum elimination rate of CREt to DPPH·, ·OH and O2-· were(97.55±0.25)%,(81.45±0.20)% and(75.28±0.41)%,IC50 were 1.629,1.789 and 5.268 mg/ml;those of CRE part to those radicals were (82.54 ± 0.36)%,(77.74 ± 0.42)% and (72.16 ± 0.73)%,IC50 were 2.481,1.918 and 6.005 mg/ml;that of CRB part to ·OH reached to(62.53±0.83)%,IC50 was 7.232 mg/ml,but to DPPH·、O2-· were less than 45%;those of CRP part and CRW part to those radicals were all lower than 40%. Each part could eliminate 3 radicals in dose-dependent manner,but were all poorer than VC group,with statistical significance (P<0.01). CONCLUSIONS:The CREt and CRE part show strongest antioxidant activities in vitro,and other parts have weak antioxidant effect.

Methylmalonic aciduria (MMA) is a common inherited autosomal recessive disorder resulting from defects in the enzyme methylmalonyl CoA mutase (MCM, mut complementation group) or in the synthesis of the MCM cofactor adenosylcobalamin (cbl complementation groups). The defects in the mut complementation group accounts for the largest number of patients with isolated MMA. At least 200 mutations in the MUT gene on chromosome 6p12 have been identified in MMA patients until now. This study aimed to investigate the clinical characteristics of MMA and genomic variations in the MUT gene of Chinese patients. Genomic DNA was extracted from 18 patients who were diagnosed as having isolated MMA by gas chromatography/mass spectrometry (GC-MS), and from some of their parents as well. Amplification and direct sequencing of the MUT coding regions (exon 2-13) and their adjacent intronic consensus splice sites were performed in order to identify the disease causing mutations. In this group, six novel mutations in the MUT gene, c.424A>G (p.T142A), c.786T>G (p.S262R), c.808G>C (p.G270R), c.1323_1324insA, c.1445-1G>A and c.1676+77A>C were identified. p.T142A and p.G270R were respectively detected at a heterozygous level in one patient. Two previously reported mutations, c.682C>T (p.R228X) and c.323G>A (p.R108H) were also found in this study. In addition, six previously described single nucleotide polymorphism (SNP), c.636A>G (p.K212K), c.1495G>A (p.A499T), c.1595A>G (p.H532R), c.1992G>A (p.A664A), c.2011G>A (p.V671I) and c.1677-53A>G were identified. In this study, we updated the spectrum of MUT mutations and identified the main MMA-causing mutations in Chinese MMA patients.

Objective To investigate the effects of telmisartan on the expression of angiotensin converting enzyme2 (ACE2) mRNA in monocyte-derived macrophages of hypertensive patients companied with diabetes.Methods 62 essential hypertensive patients companied with diabetes were randomly divided into two groups:regular treatment group,and telmisartan group.Then the content of ACE and ACE2 in serum was detected by ELISA,and the expression of ACE mRNA and ACE2 mRNA in monocyte-derived macrophages of patients was detected by RT-PCR before and after having been treated.Results (1) After having been treated for 4 weeks and 12 weeks,the blood pressure of the patients in two groups were decreased significantly,Comparing with regular group,telmisartan group seemed to have more obvious therapeutic effect (P < 0.05) ; (2) After having been treated for 12 weeks,glycosylated hemoglobin diseased in both group,but there was no significant difference between the two group (P > 0.05) ; (3) In telmisartan group,the content of ACE2 in serum was increased after having been treated for 12 weeks than that in regular treatment group,[(23.9 ± 8.2) U/L vs (16.3 ± 8.9) U/L,P < 0.05] ; and the expression of ACE2 mRNA in monocyte-derived macrophages in telmisartan group was obviously increased after 12 weeks comparing with regular treatment group (0.73 ±0.06 vs 0.51 ±0.04,P <0.01).Conclusion The role of telmisartan in decreasing blood pressure and it's advantage to the metabolism of glucose are partly related with the up-regulation of ACE2 mRNA.
