Objective To explore the effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage. Methods Seven eyes of 7 patients with neovascular glaucoma combined with vitreous hemorrhage underwent vitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy. The preoperative visual acuity ranged from light perception to 0.2, and the mean preoperative intraocular pressure was 54 mm Hg (38-64 mm Hg)(1 mm Hg=0.133 kPa). The mean follow-up was 8 months (6-15 months). Results The postoperative visual acuity ranged from light perception to 0.4, and the mean postoperative intraocular pressure was 17 mm Hg (10-30 mm Hg) which was significantly lower than preoperative one ( P

International Eye Science 2014;(10):1786-1789
AIM:To observed the variation regularity of corneal endothelial cells in patients with different diabetes duration after phacoemulsification, and investigate the effects of diabetes and its disease duration on corneal endothelial cells.
METHODS: Ninety-seven ( 135 eyes ) cataract patients with diabetes were selected randomly and divided into GroupⅠ( which diabetes duration ≥10a) and GroupII(which diabetes duration <10a) according to their disease duration. Additionally 62 (89 eyes) age-related cataract patients were randomly selected as the control group. The corneal endothelial cell density ( CD ) , proportion of hexagonal cell and coefficient of variation ( CV ) in the three group patients were measured respectively before phacoemulsification and after surgery. And the measurement results were statistically analyzed.
RESULTS:The corneal endothelial CD and proportion of hexagonal cell in the three group were decreased after surgery compared with preoperative. But the CV of corneal endothelial cells was increased on the 1 st wk and in 1st mo after surgery compared with the preoperative. The difference was statistically significant (P<0. 05). The corneal endothelial CD and proportion of hexagonal cell in the two diabetic groups were lower than the control group after surgery. However, the CV of corneal endothelial cells was higher than the control group. The difference was statistically significant ( P < 0.05 ) . There was no significant difference in the corneal endothelial CD, proportion of hexagonal cell and CV between the two diabetic groups before phacoemulsification (P>0. 05). The proportion of hexagonal cell in Group Ⅰ was lower than which in GroupIIafter surgery. While the CV was higher than which in Group II. The difference was statistically significant (P<0. 05).
CONCLUSION: Phacoemulsification has some damage on the corneal endothelial. Since the impact of diabetes on the morphology and function of corneal endothelial cell was related to the diabetic duration. So phacoemulsification has more obvious damage on the corneal endothelial in diabetic patients. And the diabetic duration was longer, the damage on the corneal endothelial in phacoemulsification was more easily.

OBJECTIVETo investigate the association of A260G and A386G polymorphisms of the DAZL gene with male infertility caused by oligozoospermia or azoospermia.
METHODSWe searched the PubMed, Science Direct, Wiley Online Library, CNKI, VIP, and CDDB databases up to November 30, 2013 for case-control studies evaluating the relationship of SNP260 and SNP386 polymorphisms of the DAZL gene with male infertility, and meanwhile conducted manual sourcing of the references in the identified studies and relevant articles. Two reviewers independently screened the title, abstract and keywords of each article retrieved. The StataSE12. 0 software was used for meta-analysis and other statistical analyses.
RESULTSTotally, 13 case-control studies were included (10 about A260G and 11 about A386G), involving 2 715 infertile patients (2 500 with oligozoospermia or azoospermia) and 1 835 normozoospermic men. DAZL A260G showed no statistical significance in the allele, dominant, recessive, co-dominant, or super-dominant gene model (P >0. 05). DAZL A386G exhibited a strong correlation with oligozoospermia or azoospermia in Asians in the allele gene model (OR = 0. 15, 95% CI 0.07 -0.34, P <0.05), dominant gene model (OR =0. 16, 95% CI 0.07 - 0. 35, P <0.05), co-dominant gene model (AA/AG) (OR = 0. 15, 95% CI 0. 06 - 0. 33, P < 0. 05), and super-dominant gene model (OR = 0. 15 (95% CI 0.06 - 0.33, P <0.05) , and so did it in Chinese in the four gene models ( OR = 0. 11, 95% CI 0.04 - 0. 28, P <0.05; OR =0. 11, 95% CI 0.04 - 0.28, P<0.05; OR = 0.09, 95% CI 0.03 - 0.26, P<0.05; OR = 0.09, 95% CI 0.03 - 0.26, P< 0.05).
CONCLUSIONOur study manifested that the DAZL polymorphism A386G, but not A260G, was correlated with reduced sper- matogenesis or sperm count specifically in Chinese males. More high-quality trials are required for a deeper insight into the exact relationship of DAZL A260G and A386G polymorphisms with oligozoospermia- or azoospermia-induced male infertility.

OBJECTIVE:To investigate clinical efficacy of oxaliplatin+calcium folinate+5-fluorouracil(mFOLFOX6),oxalipl-atin+capecitabine(CapeOX),irinotecan+calcium folinate+5-fluorouracil(FOLFIRI)for metastatic colorectal cancer,and to conduct cost-effectiveness analysis. METHODS:48 patients with colorectal cancer were divided into mFOLFOX6 group(30 cases),Cape-OX group(8 cases)and FOLFIRI group(10 cases). Clinical efficacy and ADR of 3 groups were analyzed,and cost-effectiveness analysis was also conducted. RESULTS:Clinical effective rates of mFOLFOX6 group,CapeOX group and FOLFIRI group were 96.67%,87.50% and 80.00%,respectively,the mFOLFX6 group was significantly higher than the other 2 groups,with statistical significance(P<0.05). mFOLFOX6 group had high incidence of gastrointestinal side effects (70.00%). FOLFIRI group had high incidence of myelosuppression (70.00%). CapeOX and mFOLFOX6 group suffered from liver injury possibly,without statistical significance (P>0.05). The C/E of mFOLFOX6 group,CapeOX group and FOLFIRI group were 11 950,15 674 and 18 397 re-spectively,to which results of sensitivity analysis were same. CONCLUSIONS:The cost-effectiveness of mFOLFOX6 regimen is superior to CapeOX and FOLFIRI regimen in the treatment of metastatic colorectal cancer,but it has the high incidence of gastroin-testinal side effects.
