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.

Objective To study the survival,migration and differentiation of the neural stem cells which transplanted into ventral horn of spinal cord after brachial plexus avulsion.Methods Neural stem ceils isolated from spinal cord of neogenetic rats and cultured,expanded,labeled by BrdU before transplanted. Twenty adult healthy SD rats preformed as the model of brochial plexus avulsion(Roots C_(5~7)),then transplan- rod stem ceils into the C_6 ventral horn of spinal cord.On 1,2,4,8,12 weeks postoperatively,immunohisto- chemistry assay were carried out in the spinal cord.Results Transplanted into ventral horn of spinal cord after brachial plexus avulsion.Neural stem cells can survive,migrate for at least one segment of spinal cord and differentiate to neurons and astrocytes.The differentiation of stem cells were time-depends.Conclusion Neural stem cells can survive,migrate and differentiate after transplanted into ventral horn of spinal cord in the rats which suffered from brachial plexus avulsion.

AlM: To monitor long - term changes of matrix metalloproteinase-2 ( MMP-2 ) in human tears fluid after laser in situ keratomileusis ( LASlK) .
METHODS: Thirty - two myopia cases ( 64 eyes ) underwent uneventful LASlK were enrolled in the study. Tear fluid were collected and MMP-2 expression was analyzed by Western - bolt assay preoperatively and postoperatively on 15d, at 1, 3mo, and 1a.
RESULTS:LASlK increased the concentration of MMP-2 in human tear fluid. At 15d postoperatively, the magnitude of MMP-2 was 1. 4 times that of preoperative, thereafter subsided, but didn't return to preoperative level by 3mo ( P < 0. 05 ). Up to 1a after surgery, the concentration of MMP-2 almost recovered (P>0. 05).
CONCLUSlON: MMP- 2 is significantly expressed in human tear fluid after LASlK, then subsided with time, but didn't return to preoperative level by 3mo and almost recovered up to 1a, indicating wound healing of LASlK would continue up at least 3mo after surgery and almost recovered 1a postoperatively.

This study aims to investigate the change of plasma concentration of digoxin (DIG) in rats with ovariectomy. Twelve female SD rats were randomly assigned into ovariectomized group and sham group (n = 6). All rats plasma was collected after a single dose of 2 mg x kg(-1) DIG administrated orally, serum DIG concentration was determined by LC-MS/MS. The level of P-gp in the intestinal was analyzed by Western blotting. Pharmacokinetic calculations were performed on each individual using DAS 2.0 practical pharmacokinetic software. Compared with the sham group, C(max) of ovariectomized group decreased significantly (P < 0.01). There was no significant difference of AUC(0-t), and the level of P-gp was elevated in ovariectomized group. It was found that C(max) of DIG was significantly reduced after ovariectomy, and the change was associated with the decreased level of estrogen, which contributes to the increased level of P-gp.

BACKGROUND:The obesity has led to a plenty of diseases including hypertension, coronary heart disease, fatty liver, hyperlipidemia, and type 2 diabetes. Therefore, understanding the mechanism of adipocyte differentiation is of far-reaching significance to the prevention and treatment of obesity. For the current studies of the mechanism of adipocyte differentiation pay more attention to microRNA, rather than long non-coding RNAs (lncRNAs). OBJECTIVE:To obtain the lncRNAs whose fold change was apparent during adipogenic differentiation, and to further screen the lncRNAs that possibly play a crucial role in adipogenic differentiation for verification. METHODS:Subcutaneous fat was obtained from human abdomen. Adipose-derived stem cells were col ected using tissue culture method. The third passage of adipose-derived stem cells was used for adipogenic differentiation. Through microarray technology, the expression levels of lncRNAs and mRNA were analyzed at 0, 5 and 12 days in adipogenic differentiation. Combining with bioinformatics report, lncRNAs apparently presented fold change were screened and verified by qRT-PCR. RESULTS AND CONCLUSION:Fold change 1.5 (P<0.05) was considered as a criterion during adipogenic differentiation. The number of up-regulated lncRNAs was 748 for 5 days versus 0 day, 847 for 12 days versus 0 days, 593 for 12 days versus 5 days. At the same time, the down-regulated number was 828 for 5 days versus 0 day, 1 113 for 12 days versus 0 day, 750 for 12 days versus 5 days during adipogenic differentiation. In combination with bioinformatics analysis results, 3 of 28 lncRNAs were related to lipid metabolism:AK304548, BP216319 and DA852857, according to the standard that fold change in 0, 5 and 12 days was higher, and the target genes were known to be associated with adipogenesis-related genes. PCR results showed that the expression of AK304548 and BP216319 and its target gene presented an up-down trend, which is consistent with the microarray sequencing results. These results indicated that lncRNA plays a critical regulatory role in the adipogenic differentiation.

Objective To investigate protein expression of telomerase reverse transcriptase(TERT),telomerase-associated protein 1(TP1) and telomeric repeat binding factor 2(TRF2) in human fetal cadiacmyocytes.Methods Using immunohistochemical method,sections of human fetal hearts were stained with antibodies against TERT,TP1 and TRF2.Results Expression of TERT was gradually decreased with development in human fetal cadiacmyocytes nuclear.Expression of TP1 and TRF2 was gradually increased with development in human fetal cadiacmyocytes cytoplasm.Conclusion Down-regulation of TERT and up-regulation of TP1 and TRF2 may promote the permanent withdrawal of cardiomyocytes from the cell cycle and enter terminal differentiation and myocardium hypertrophy.
