Objective To evaluate the relationship between thyroid autoantibodies (ATA)and pregnancy outcome of infertility women after assisted reproductive technology (ART). Methods Relevant studies were identified by searching PubMed, Cochrane library, CNKI and CBM. Results 7 studies were appropriate for meta-analyses and total 4165 patiens were included. Meta analysis shows that the pregnancy rate difference between ATA positive patients and controls have no significance, but the miscarriage rate is greater significant between them. In the meta-analyses, the presence of thyroid antibodies was associated with an increased risk of miscarriage (OR 1.85, 95%CI 1.32~2.59), compared with the absence of thyroid antibodies. Conclusion Pregnant women with thyroid antibodies have an increased risk of complications, especially miscarriage. Future research,should focus on the treatment and thyroid disease on pregnancy outcome.

AIM: To explore the long-term efficacy of Q-factor guided laser epithelial keratomleusis ( LASEK ) for myopia and astigmatism with positive Q-factor.
METHODS: There were 158 eyes which were myopia and astigmatism with positive Q- factor taken in two groups randomly: 86 eyes accepted Q - factor guided LASEK as observation group and 72 eyes accepted routine LASEK as control group. The difference between the two groups about all data was similar. The uncorrected visual acuity ( UCVA ) and the best corrected visual acuity ( BCVA ) as well as diopter, ocular tension, corneal topography, Keratometry value K, aspherical factor Q, Higher-order aberrations ( HOA ) , corneal thickness by ultrasound and, contrast sensitivity ( CS ) , Haze were examined and compared before and after surgery. All the cased were followed up for 14d, 1, 3, 6, 12mo. And there were no statistical difference among the data before surgery.
RESULTS: After 12mo there were no statistical difference between the two groups about UCVA and BCVA. But the safety index of observation group was 1.10, that of control group was 1. 07. The validity index of observation group was 1. 06, that of control group was 0.99. The HOA of observation group was 0. 45±0. 17μm, and that of control group was 0. 72±0.25μm, there was statistically significant difference (t=-8. 193,P=0. 000). Q factor of observation group was 0. 41±0. 17, that of control group was 0. 77±0. 22, there was significant difference (t=11. 377,P = 0. 028). The contrast sensitivity of 3mo post surgery of patients in the observation group returned to the level of before surgery. But in the control group the contrast sensitivity of the patients did not returned until 6mo.
CONCLUSION:Q-factor guided LASEK for myopia and astigmatism with positive Q-factor is stable, safe and effective. The operation allow for reducing the high order aberrations, maintaining the most asphericity of cornea, saving more in corneal tissue, which cause faster recovery of contrast sensitivity, less haze and better visual quality.

Objective To determine the value of complexed prostate-specific antigen (cPSA) in predicting metastasis in patients with prostate cancer.Methods From January 2012 to April 2014,the clinical data of 74 patients with newly diagnosed prostate cancer in our hospital was retrospective reviewed.The prostate cancer was diagnosed by transrectal ultrasound guided biopsy and postoperative pathologic diagnosis.The patients were divided to 2 groups according to metastases status.There were 38 patients in the group of metastasis and 36 patients in the group of without metastasis.In metastasis group,the bone metastasis was found in 36 cases.There is only one case with lung metastasis and one case with lymph node metastasis.In the group without metastasis,the T stages classification were T1-T2 in 17 cases and T3-T4 in 19 cases.While,10 cases with T1-T2 stage and 28 cases with T3-T4 stage were confirmed in the group with metastasis.There was no statistical significance of T stages and mean age in two groups (P＞0.05).The level of cPSA in the serum was detected by chemiluminescent immunoassay,the level of tPSA,fPSA were detected by electro-chemiluminescent immunoassay,fPSA/tPSA,cPSA/tPSA were evaluated and the corresponding specificity were calculated.The correlation of age with tPSA,cPSA were analysed.The differences in PSA,fPSA/tPSA,cPSA/tPSA were compared between metastasis and non-metastasis group.ROC curve analysis was used to determine the diagnostic value of cPSA and tPSA,In the meantime,area of ROC curves were compared by Z test.Results The age was not related to the value of tPSA (r=-0.09,P=0.12) and cPSA(r=-0.38,P=0.14).The median levels of tPSA,fPSA,and cPSA are 29.88μg/L,2.18 μg/L and 18.86 μg/L in the group without metastasis,respectively.The median levels of tPSA,fPSA,and cPSA were 410.05 μg/L,51.50 μ.g/L and 290.40 μg/L in the group with metastasis,respectively.Significant differences of those results could be found in two groups (P＜0.05).fPSA/tPSA was 0.07 and cPSA/tPSA was 0.79 in the group without metastasis.fPSA/tPSA was 0.08 and cPSA/tPSA was 0.80 in the group of metastasis.fPSA/tPSA (P=0.77),cPSA/tPSA (P=0.64) in patients with metastasis were not greater than in those without metastasis (P＞0.05).The area under the curve of tPSA and cPSA were 0.83 (95％ CI 0.73-0.93) and 0.82 (95％CI 0.73-0.92) respectively.Analysis of ROC curves showed that the AUC for cPSA is not significant different from tPSA (Z=1.64,P=0.10).The specificity of cPSA was 22.2％ which is higher than that of tPSA (19.4％) at a sensitivity of 92.1％ in predicting metastasis comparing with the patients without metastasis.The sensitivity could reach to 90.0％ when the cut off value of tPSA was 9μg/L or the cut off value of cPSA was 7 μg/L.Conclusions In our study,a preliminary validation that cPSA is useful for predicting the metastasis in patients with prostate cancer was made.
