AIM: To evaluate the clinical effect and the rotational stability of AcrySof Toric intraocular lens ( IOL ) implantation to correct preexisting corneal astigmatism in cataract surgery.
METHODS: Twenty-three patients ( 28 eyes ) were enrolled from the department of ophthalmology in the first Affiliated Hospital of Nanjing Medical University. All patients underwent similar phacoemulsification procedure combined with AcrySof Toric IOL implantation from June 2012 to December 2013. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA ) , anticipated residual astigmatism, postoperative residual astigmatism, and Toric IOL axis were detected and measured.
RESULTS:Three months after operation, the UCVA of all eyes were 0. 75±0. 16 and the BCVA were 0. 84±0. 15, there was no significant difference between UCVA and BCVA ( t = 1. 036, P>0. 05 ). The anticipated residual astigmatism was ( 0. 28±0. 12 ) D. The actual residual astigmatism after 3mo of the operation was (0. 42±0. 17) D. There was no significant difference between anticipated and actual residual astigmatism (t=1. 259, P>0. 05). The mean axis rotation of Toric IOL was 3. 02o±1.56o (0o-7o) after 1d of operation and 3. 28o±1. 85o (0o-7o) after 3mo. Among all the eyes, 25 eyes ( 89%) rotated <5o, in 3 eyes (11%) rotated 5o-7o.
CONCLUSION: The AcrySof Toric IOL implantation shows good effectiveness, predictability and stability in correcting pre-existing astigmatism in cataract patients.

Minichromosome maintenance protein 7 (MCM7) is an important regulator of DNA replication,and plays an important role in replication initiation and elongation steps.Recent studies show that MCM7 is closely related with the formation and growth of digestive tumors.The detection of MCM7 protein can provide new ideas for the early diagnosis,treatment and prognosis of the digestive tumors.

Objective To develop the human colon carcinoma(HT-29) liver metastasis model in nude mice,and to detect the expression of human telomerase reverse transcriptases(hTERT) mRNA in liver of nude mice. Methods Liver metastases were established in 30 Balb/c nude mice by intrasplenic injection of colonic cancer cells(HT-29),and the spleens were resected.After being sacrificed,the tumor growth was observed,and the pathological examinations were performed.The expression of hTERT mRNA in the livers of nude mice was detected by RT-PCR technique. ResultsHuman colon carcinoma(HT-29) liver metastasis model was developed in all the 30 nude mice,with the liver metastasis rate of 100%.The pathological results revealed the occurrence of liver metastases,and the expression of hTERT mRNA was positive in the liver tissues. Conclusion Intrasplenic injection of HT-29 cell is a reliable way for producing colonic cancer liver metastasis model,and the positive expression of hTERT mRNA in liver tissues indicates the significance of hTERT in the early diagnosis and treatment of colon carcinoma liver metastasis.
