AIM:To discuss the application effect of adjustable sutures in glaucoma filtering operation after trabecular resection.
METHODS: Seventy-eight cases ( 101 eyes ) suffered from glaucoma were randomly divided into two groups, observation group and control group. Thirty-nine cases ( 51 eyes ) in the observation group underwent trabeculectomy with adjustable sutures, the control group (39 cases, 50 eyes) only adopted trabeculectomy.RESULTS: Compared Preoperative IOP in two groups, the difference was not statistically significant (P>0. 05). After 6mo, IOP were decreased compared with preoperative in two groups, and that in observation group was lower than control group, the difference was statistically significant ( P < 0. 05 ). Six months after operation, there were 1 eye with shallow anterior chamber Ⅰ and 2 eyes with non- functional bleb in observation group, and the complication rate was 5. 9%. While there were of 6 eyes with shallow anterior chamber, in which 4 eyes at gradeⅠ, each one at gradeII and Ⅲ. Non-functional blebs in 5 eyes and a scleral flap adhesion complications rate in the control group was 24. 0%, significantly higher than that in the observation group, the difference was statistically significant ( P<0.01).
CONCLUSION: The adjustable sutures combined with trabeculectomy for glaucoma can significantly reduce the postoperative complications. The curative effect is exact and clinically applicable.

Eukaryotic DNA element called Matrix Attachment Regions (MARs) can function on regulating the structure and activity of chromosome. Traditional quantitation in vitro and indirect functional analysis can not always reflect MAR-involved physiological state. In order to study transcription regulation and make a try in methodism,? 1-antitrypsin MAR (?1-AT MAR) is cloned and incorporated into pEGFP-C1 vector. Non-MAR-containing and MAR-containing plasmids were then transfected into HEK-293 cells with LipofectamineTM 2000 respectively. Positive cell clones were assayed after 20 days of selection by G418. Semiquantitative RT-PCR and fluorescence microscope analysis show that this MAR has a positive effect on modulating nearby gene expression. Further, co-localization with newly CMV promoter and RNA polymeraseⅡ(RNAPⅡ) was detected by chromatin immunoprecipitation (ChIP), The PCR result demonstrates that more RNAPⅡwas recruited to the CMV promoter to initiate transcription in presence of MAR. ChIP can be used to confirm the MAR-mediated transcriptional activation and provide more reliable information than RT-PCR in real time. The technology is also providing a platform for our research in gene expression regulation.

To investigate the relationship between diabetic macular edema (DME) and serum E-selectin level.
●METHODS: Totally 90 patients with diabetic retinopathy in our hospital from October 2009 to October 2013 were observed. Retrospective analysis of the correlation between macular edema degree and serum soluble E -selectin ( sE - sel ). Ninety patients with diabetic retinopathy were divided into two groups: DME group and non - DME group. The level of sE - sel and microalbuminuria (MA) of two groups were determined and compared.
●RESULTS: There was significant difference in MA, sE-sel levels of groups ( P < 0. 05). The value of diabetic retinopathy patients with sE - sel and MA, FBG were positively correlated ( r = 0. 728, P < 0. 05; r = 0. 651, P <0. 05).
●CONCLUSlON: Elevated levels of sE-sel is a risk factor for diabetic macular edema, and sE-sel was involved in the pathogenesis of diabetic microangiopathy.

Glyoxalase system,a most effective defence system is present in cytosol of cells to scavenge ?-oxoaldehydes,which are reactive intermediates of AGEs formation.Glyoxalase Ⅰ is the key enzyme of this system.?-oxoaldehydes and AGEs are involved in the development of Alzheimer′s disease (AD). Therefore,the expression level and activity of glyoxalase I are essential to pathogenesis of AD.

After an account of the background to the practice of letting patients pick their doctors in the Third Central Hospital of Tianjin, the paper points out the positive impact of the practice, comments on the specific measures, and narrates the results that have been achieved. These include: ①enhanced awareness of self management on the part of the staff; ②increased cohesion of the hospital; ③higher efficiency; ④greater initiative on the part of the scientific and technical personnel as a result of the reform; ⑤social recognition of the reform; and ⑥a higher level of professional ethics building. Lastly the paper discusses the hospitals experience in adopting the practice of letting patients pick their doctors.

[Objective]To compare the outcome and complication rates following nonoperative and those after ptate fixation of displaced midshaft clavicular fractures.[Method]Between March 2001 and December 2005,the data of 110 patients with a displaced midshaft fracture of clavicle were retrospective analyzed.Among them,62 patients were treated with plate fixation,including 53 male and 9 female patients aged 33.5 years old averagely.48 patients were treated with closed reduction and a figure-of-eight bandage applied,including 33 male and 15 female patients aged 33 years old averagely.Following enrollment in the study,the patients were seen at six weeks and at three,six,and twelve months.Assessment included standardized clinical evaluation,completion of the Constant shoulder score,complication and plain radiographs.Radiographic union was defined as complete cortical bridging between proximal and distal fragments on radiograph.[Result]All patients completed one year of follow-up.Constant shoulder score were significantly improved in the operative fixation group at all time-points(P

Objective: To investigate the effect of all trans retinoid acid (ATRA) on bone cell proliferation and differentiation. Methods: Newborn rat calvarial osteoblastic cells were isolated and the metabolism of the osteoblastic cells were determined by MTT, Goldens method and immunocytohistologic method. Results: 10 -5 , 10 -6 , 10 -7 , 10 -8 , 10 -9 mol/L ATRA could increase osteoblastic cells proliferation after 72 h culture; 10 -5 , 10 -6 , 10 -7 mol/L ATRA could increase ALP activity. The expression of cyclin D 1 was decreased. Conclusion: ATRA stimulates the proliferation and differentiation of rat calvarial osteoblastic cells in vitro. Cell cycle relative proteins may play an important role in control of cell proliferation and differentiation induced by retinoic acid and derivatives.

There is immense interest in the long-chain polyunsaturated fatty acids(LC-PUFAs) on account of their health-beneficial properties.There has been considerable interest in the production of LC-PUFAs in transgenic plants to provide a cheap,sustainable and clean source of these fatty acids.Several main LC-PUFAs,their roles and metabolic pathway in plant are introducedbriefly,progresses on biosynthesis of LC-PUFAs in transgenic plant are reviewed,and strategies for improving the yields of LC-PUFAs in plant are also discussed.
