International Eye Science 2017;17(7):1337-1339
AIM:To investigate the effect and safety of modified small incision cataract surgery in patients with soft core cataract.METHODS: Totally 80 cases (109 eyes) of soft cataract patients who underwent surgical treatment from January 2015 to May 2016 in ophthalmology center of our hospital, using random number table method were divided into improved group (improved manipulation of small incision cataract surgery), traditional group (traditional approach to small incision cataract surgery), 40 cases in each group.Comparison of the two groups of treatment, the incidence of complications were taken.RESULTS: There were no significant differences on uncorrected visual acuity between the two groups before and at 1d, 1wk and 1mo after operations (P>0.05).The uncorrected visual acuity of the two groups improved significantly at 1d, 1wk and 1mo after operations compared with those before operations (P<0.05).There were no significant differences on intraocular pressure(IOP) between the two groups before and at 1d, 1wk and 1mo after operations (P>0.05).The IOP of the two groups increased significantly at 1d, 1wk and 1mo after operations compared with those before operations (P<0.05).The complication rate was 9% (5/54) in the modified group, significantly lower than that in the conventional group 25% (14/55) (P<0.05).CONCLUSION: Improved small incision cataract surgery for soft cataract patients was with reliable results, less complications.
2.Study on the processing of silk biomaterial and its application in tissue engineering
International Journal of Biomedical Engineering 2008;31(3):188-191
Silk fiber,as a kind of natural polymer,has been used as surgical sutures in clinic for years.Silk fiber is composed of a filament core protein,termed fibroin and a glue-like coating called sericin proteins.Due to its unique mechanical properties,good biocompatibility and slow degradability,silk fiber has been put in variety of applications as a new kind of biomedical scaffolds in recent years.With the development of the processing technique,silk fiber can be processed through the new versatile processing method to form various forms of scaffolds and its surface could be modified for different purposes.Further more,it could be tailored through genetic recombination to form the silk fibroin-like polymers which has a promising potential in medical applications.

Objective To screen the genes related to novel gene AngReml04. Methods Gene chip was employed to detect the genes related to AngRem104 by its over-expressed constructs, which was produced by transfection of the sense- and antisense-AngReml04 into human mesangial cells, and then RT-PCR was used to confirm the up-regulated expression of related genes. Results There were 94 genes up-regulated and 2 genes down-regulated when AngRem104 was over-expression. The different expression genes were cataloged as extracellular matrix and receptor protein, DNA-binding and transcription-related protein, immune-related protein, cytoskeletal and dynamic protein, synthesis and metabolism related protein. Fibronectin (FN) and integrin beta 1 (fibronectin receptor) were dramatically over-expressed in the top of all up-regulated genes. Furthermore, the correlative expression between AngReml04 and FN was detected by RT-PCR. Conclusion Gene chip not only demonstrates the clues for further investigation of novel gene AngRem 104, but also reveals the co-expression of AngRem104 and fibronectin.

AIM: To study the expression and function of novel gene AngRem104. METHODS: Northern blot was performed to detect the distribution of AngRem104 in human multiple normal tissues as well as the effect of AngⅡ and AT1R antagonist (losartan) on AngRem104 expression. The sense and antisense eukaryotic expression vectors of AngRem104 were constructed and transfected into human mesangial cells. RT-PCR was used to detect the expression of FN when AngRem104 was over-expressed. Primary sequence and motif analysis of AngRem104 protein were performed by on-line ExPasy predictive tools. RESULTS: AngRem104 was predicted to localize at the cellular nucleus. It was widely expressed in human heart, placenta, liver, muscle, kidney and pancreas. Moreover, the up-regulated expression of AngRem104 induced by AngⅡ was inhibited by losartan in a dose-dependent manner. CONCLUSION: AngRem104 is a novel nuclear protein related to the expression of fibronectin and could be up-regulated by AngⅡ in human MC.

Aim To study the effect and investigate the underlying mechanism of astragaloside Ⅳ on contraction and relaxation in isolated rat aortic rings.Methods The relaxation effect of astragaloside Ⅳ(1~100 mg?L~(-1))on phenylephrine-preconstricted aorta ring was recorded.The effect of astragaloside Ⅳ on the contraction induced by cumulative phenylephrine,KCl or CaCl_2,was recorded respectively.Results Astragaloside Ⅳ dilated aortic vessels in a dose-dependent manner,which was partly inhibited by preincubation with non-selective nitric oxide synthase inhibitor,guanylyl cyclase inhibitor and cyclooxygenases inhibitor indomethacin.Astragaloside IV could also antagonize phenylephrine-,KCl-and CaCl_2-induced vessel contraction.Conclusion Astragaloside IV dilated aortic vessels partially though endothelium-dependent NO pathway and inhibited vessel contraction via interfering Ca~(2+) influx.

Myocardial hypertrophy is the complication of many cardiovascular diseases that induce cardiac remodeling.The molecular mechanism of cardiac remodeling involves abnormal changes in various transmembrane ionic currents in the heart.Recent studies suggest the potential involvement of volume-regulated Cl-current(ICl.Vol)in cardiac hypertrophy.Although the molecular basis of ICl.Vol remains to be elucidated,recent progress is reviewed in the potential role of ICl.Vol in cardiac remodeling.

Schistosomiasis is a neglected tropical disease that severely threatens human health and affects the socioeconomic development. The causative agent that parasitizes in humans mainly involves Schistosoma japonicum,S. mansoni,S. haematobi-um,S. intercalatum and S. mekongi. As the firstly identified schistosome,S. haematobium infection is found to strongly correlate with bladder cancer. This paper mainly reviews the discovery,morphology and life cycle of S. haematobium.

Objective To study the different curative effect between r-tPA application and urokinase in the interventional therapy for acute and severe pulmonary embolism.Methods Analyzed the clinical date of 22 cases acute and severe pulmonary embolism patients,and classified them into two groups according to the application of r-tPA and urokinase to compare the changes of their blood pressure,heart rate,arterial partial pressure of oxygen,hemachrome and pulmonary arterial pressure before and after therapy,meanwhile,record the thrombolysis time that the two groups took.Results The thrombolysis effect time adopting urokinase was remarkably longer than that thrombolysis adopting r-tPA(P<0.05); The blood pressure,heart rate,arterial partial pressure of oxygen of the two groups gained remarkable improvement after therapy(P<0.05).The pulmonary arterial pressure of the urokinase group dropped obviously after operation(P<0.05),while the r-tPA group dropped not so significantly after operation.The hemachrome of the two groups did not dropped significantly after operation.Conclusion The r-tPA and urokinase are both effective to interventional therapy for acute and severe pulmonary embolism,while r-tPA can clearly shorten the time in thrombolysis and could reduce any bleeding risk.
