Objection To study the effect of letrozole on EM rat models and influence on the reproductive system. Methods Surgically transplanted autologous uterine tissues to ectopic site beside the uterines in rats were used as animal models to study endometriosis. 20 EM model rats were random divided into letrozole-treated group and saline solution-treated control group. The change of ectopic lesion volume in each group was compared before and after treatment. Apoptotic cells were assessed by the terminal deoxynucleotidyl transferase-mediated deoxy-UTP nick-end labeling (TUNEL) assay, and the uterian horn and ovary were weighted and observed by optical microscopy to study the change of morphology. Results The volumes of the endometriotic tissues of letrozole group reduced more than that in control group[ ( 28. 75 ± 2.28 )mm3 vs ( 108.39 ±9. 98)mm3, P <0.01 ]. The apoptotic rate in letrozole group [ (5.52 ±2. 81 )% ]was higher than control group[ (2.11 ± 1.70)%, P <0. 01 ]. The ovarian weights in letrozole-treated group increased significantly[ (25.25 ± 9. 89) mg/100g vs ( 13. 10 ± 2. 70 ) mg/100g, P < 0. 01 ], arid the ovaries showed polycyst. The uterian weights in letrozole-treated group[ (41.46 ± 15.81 ) mg/100g vs (94. 81 ±18.00) mg/100g, P <0. 05 ] significantly decreased, and the endometriums presented atrophy. Conclusion Letrozole treated EM by means of increasing the apoptosis of the ectopic tissues. Letrozole would give ovarian over stimulating and the uterian weighting decreased as well as endometriums atrophy.

Objective To investigate the distribution of weak D and Del phenotype in unrelated blood donors with negative Rh (D). Methods Four hundred and nineRhD (-) unrelated donors were screened by the saline agglutination method. Type weak D was detected by the indirect antiglobulin test, and type Del was detected by absorb radiation method. Results In 409 RhD (-) samples, 27 cases (6.61%) of type weak D were checked out, and 61 cases (14.91%) were type Del and 321 cases (78.48%) were corroborate for RhD (-), In the confirmed RhD (-) blood donors, phenotype ccee was most (49.14%), followed by Ccee (23.47%), People with phenotype ccEe accounted for 4.16%in type weak D, followed by Ccee (1.71%). Ccee accounted for 10.02%in type Del, and Ccee accounted for 1.71%. Conclusion RhD (-) donors screened by regular testing should adopt a more sensitive test for verifing type weak D or Del. In order to ensure the security of blood transfusion, people with type weak D and Del should be regarded as RhD positive blood donors, and the RhD negative people deemed to be recipients.

Objective To investigate the relationship between Toxoplasma gondii(TOX)infection and abnormal pregnancy outcomes. Methods A total of 126 cases of abnormal pregnancy women in the Department of Obstetrics and Gynecology,the Fourth People’s Hospital of Langfang from March to December 2013 were chosen as an experimental group,and 263 cases of normal pregnancy women of childbearing age as a control group. The TOX-IgM and-IgG antibodies were detected by ELISA. The data in the two groups were processed and analyzed by SPSS13.0. Results The positive rates of TOX-IgM,-IgG in 126 cases of abnormal pregnancy women were 7.94%and 19.84%respectively,and 1.90%and 8.75%in the control group respectively,and there were significant differences between them(χ2IgM=6.82,χ2IgG=9.70,both P<0.01). The positive rates of TOX-IgM,-IgG in the normal pregnancy women were lower than those in 4 sub-groups of abnormal pregnancy women,and all the differences were statistically significant(χ2spontaneous abortion = 10.40,χ2premature delivery = 9.03,χ2embryo damage =4.32,χ2birth defect = 4.04,all P<0.05). However,the TOX-IgM,-IgG positive rates in the 4 sub-groups of abnormal pregnancy women had no statistically signifi-cant difference(P > 0.05). Conclusions TOX infection could cause serious abnormal pregnancy outcomes. Therefore,the comprehensive control measures should be strengthened.
