With the increasing perfection and improvement of microsurgery technique in modern ophthalmology, especially the popularization of micro-incision cataract extraction and the rise of femtosecond-laser-assisted cataract extraction, the cataract extraction and intraocular lens implantation is gradually transformed from vision rehabilitation surgery into refractive surgery and people also pursue better postoperative visual experiences. However, the preoperative and postoperative corneal astigmatism is always the main factor affecting the postoperative visual effect. ln recent years, the development of design and materials of the intraocular lens ( lOL) provided necessary basic conditions for clinical application of the Toric lOL. The Toric lOL is primarily characterized by effective correction of cataract patients′postoperative corneal astigmatism, which results in the enhancement of patients′postoperative visual function. ln this paper, the design, classification and clinical application of Toric lOL were analyzed, and current problems and prospect were discussed.

In order to investigate the impact of fulvic acid (FA) on the hydroxylysyl glycosylation in collagen bio-synthesis, 40 NMRI mice were divided into two groups (n = 20 in each group, consisting 10 females and 10 males). The animal was maintained for two generations by different diets: control group with normal water and food and study group with water containing 30 mg/L FA and normal food. The second generation of the animal was slaughtered, and the biochemical parameters of collagen content and the degree of collagen hydroxylysyl glycosylation in skin, rib and tibia were detected by biochemical methods. The mean value of collagen in the study group was increased slightly, and no significant difference between study group and control group was found (P > 0.05), but the content of glucose-glactose-hydroxylysine (GGH) was significantly decreased in the study group in comparison with the control group (P<0.01). It was suggested that through the decrease of GGH 30 mg/L FA could inhibit the activity of galactosyl-hydroxylysylglucosyl-transferase and further disturb the post-translational modification of collagen intracellularly.

AlM:To study the treatment effect of traditional Chinese medicine in the treatment of high myopia macular hemorrhage, using Chinese medicine etiology and pathogenesis, syndrome differentiation treatment, and provide the basis for the clinical treatment. METHODS: Eighty patients ( 135 eyes ) with high myopia macular hemorrhage were selected in the hospital from January 2012 to september 2014 as treatment group, and applied traditional Chinese medicine treatment. Forty-five patients (64 eyes) with the same period, as the control group, received routine western medicine treatment. After 1mo treatement, the treatment effect and vision improvement situation of two groups were observed, and after 6mo follow-up, the relapse was observed.RESULTS: The total effective rate of treatment group was 85. 19% (115/135), higher than the control group 78. 13% (50/64) (P<0. 05). The average corrected visual acuity of treatment group was 0. 48±0. 11, higher than the control group 0. 36 ± 0. 09, the difference was statistically significant (P<0. 05). The average diopter and macular bleeding scope of the treatment group were -9. 81±0. 85D and 0. 51 ± 0. 27PD, lower than the control group -10. 76 ± 0. 91D and 0. 78 ± 0. 23PD, the differences were statistically significant ( P < 0. 05 ). The eye ground hemorrhage absorption time of treatment group was 25. 34±2. 28d, less than the control group 29. 72 ± 2. 13d, the difference was statistically significant (P<0. 05). The bleeding again of the control group 7. 81% ( 5/64 ), higher than the treatment group was 5. 19% (7/135), the difference was statistically significant (P<0. 05).CONCLUSlON: Evidence-based treatment of traditional Chinese medicine for high myopia macular hemorrhage has good clinical effect, can shorten the treatment time, and is beneficial to the recovery of postoperative vision, worthy of clinical popularization and application.

OBJECTIVETo explore the effect of Dandi Tablet (DDT), a TCM preparation for tonifying Shen and activating blood circulation, on blood lipids and sex hormones in women of postmenopausal stage.
METHODSSeventy-three women were randomly divided into two groups. The 46 subjects in the DDT group were treated with DDT (consisted of prepared Rehmannia Root 24 g, Dogwood Fruit 9 g, Poria 9 g, Water-plantain 9 g, Tuber Peony bark 9 g, Chinese Yam 12 g and Red Sage 15 g, etc.) twice a day, 4 tablets each time. The 27 subjects in the control group were treated with nylestriol (each tablet contains 2.5 mg of 17 alpha-ethynylestriol-3-cyclopentyl ether) 5 mg every month, for 3 successive months. Levels of blood lipids, including total cholesterol (TC), triglyceride (TG), high and low density lipoprotein cholesterol (HDL-C, LDL-C), apoprotein A and B (apoA, apoB) and sex hormones, including follicular stimulating hormone (FSH) and estradiol (E2) were determined before and after treatment.
RESULTSCompared with pre-treatment, after treatment, levels of TC/HDL-C and FSH significantly lowered, HDL-C and E2 increased in both groups (P < 0.05 or P < 0.01), levels of TG lowered and apoA increased significantly in the DDT group (P < 0.05).
CONCLUSIONDDT has the effect of elevating levels of estrogen and improving blood lipid metabolism, therefore shows a coronary heart disease preventive effect in women of postmenopausal stage.

OBJECTIVETo verify the existence and significance of calcium/calmodulin dependent serine protein kinase/inhibitors of differentiation 1 (CASK/Id1) pathway in fibroblasts of human keloid.
METHODSImmunofluorescence laser was used to confirm CASK and Id1 protein expression and localization in fibroblasts of the keloid and normal skin. RT-PCR and Western-blot were adopted to analysis the CASK and Id1 expression and differences between keloid and normal skin fibroblasts. The natural combination of CASK and Id1 protein of keloid fibroblasts was tested by immunoprecipitation.
RESULTSCASK and Id1 protein expression were both found in fibroblast cells of keloid and normal skin under normal circumstances. Most of CASK and Id1 were distributed in the cytoplasm and nucleus of fibroblasts. The results of RT-PCR showed that the expression of CASK mRNA in the keloid group was 0.658 +/- 0.024, which was lower than that in the normal control group (1.076 +/- 0.008, t = 11.159, P < 0.05). The expression of Id1 mRNA was 0.497 +/- 0.014, which was higher than that in the normal control group (0.307 +/- 0.017, t = 15.148, P < 0.05). The results of Western-blot showed that the expression level for CASK protein in the keloid group was 0.057 +/- 0.006, which was lower than that in the normal control group (0.168 +/- 0.012, t = 13.524, P < 0.05); the expression of Id1 protein was 0.812 +/- 0.035, which was higher than that in the normal control group (0.368 +/- 0.031, t = 16.356, P < 0.05). The results of immunoprecipitation showed that Id1 could be detected in the CASK precipitate, while CASK also could be detected in the Id1 precipitate. There was a natural binding of CASK and Id1 in keloid fibroblasts.
CONCLUSIONCASK/Id1 signal pathway may be existed and involved in the proliferation of keloid fibroblasts, which is related with the occurrence of keloid.

Objective To study the normal angiographic anatomy and variations of rabbit hepatic vessels,and explore the optimal method for hepatic artery catheterization.Methods 30 rabbits were divided into two groups randomly.Modified surgical method and interventional method were used to catheterize hepatic artery respectively,and followed by angiography to demonstrate the normal anatomy and variations of rabbit celiac artery,hepatic artery and portal vein.Results The route and distribution of rabbit celiac artery and hepatic artery were very different from human's.The commonly seen variation showed the differences in branching bifurcation of hepatic-gastric artery,with the incidence of 13.3%.The rates of successfully hepatic artery catheterization with surgical and interventional methods were 86.6%(13/15)and 80%(12/15)respectively (P>0.05).The surgical method will not be successful,whenever there's variation.Conclusion The normal anatomy and variation of rabbit celiac artery and hepatic artery are quite different from human's.Both surgical and interventional catheterizations could be rather successful but possessing advantages and disadvantages of each its own.
