Objective To evaluate the long-term effect of phacoemulsification (PHACO)+intraocular lens implantation (IOL) for cataract combined with primary angle closure (PAC) in the expansion phase. Methods Thirty-eight eyes of 29 patients which suffered from cataract combined PAC in the expansion phase had undergone PHACO+IOL and goniosynechialysis from June 2005 to December 2006 were retrospectively studied. Results A total of 32 eyes of 24 cases were followed up for 6 to 35 months post-operatively, meanly 19.53?8.93 months. The intraocular pressure (IOP) was significantly decreased from a preoperative mean of (31.61?9.88) mmHg without medication therapy to (16.73?2.13) mmHg in 1 month after operation and (15.61?1.94) mmHg at the end of follow-up. The differences between the untreatment and the treatment were statistically significant (P=0.000). The best corrected visual acuity (BCVA) was significantly improved in all cases (P=0.000). Although the BCVA at the end of follow-up was declined when compared with the acuity 1 month post-operatively, there was no significant difference. The mean central anterior chamber depth was increased from (2.22?0.51) mm preoperatively to (3.59?0.46) mm in 1 month after operation and (3.17?0.35) mm at the end of follow-up with significant differences (P=0.000). The angle of anterior chamber in all operated eyes became wider and the parts of angle closure opened at different degrees. All of patients had no any vision defection. Conclusion PHACO+IOL and combined with goniosynechialysis blocks primary angle-closure glaucoma course, and has better long-term effect.

Stem cells are a group of undifferentiated cells with indefinite self-renewal and pluripotent differentiation ability.They are able to differentiate into precursor/progenitor cells and a variety of cell types and further regenerate new cells to be involved in the repair and rebuilding of injured tissue.Therefore,stem cells are becoming the major research objects in the study on tissue engineering therapy and regenerative medicine.As a sense organ composed of several kinds of neurons and other cells,eyes possesse the dominant superiority in stem cell transplantation therapy because of its good operation controllability and visuality,less demand for seed cells and low rejection after transplantation.These advantages have aroused growing interesting of the fundamental research and clinical trail in stem cell transplantation for irreversible eye diseases.Some exciting advances in the field of stem cell fundamental research,several phase Ⅰ/Ⅱ clinical trials are in progress.The patients with degenerative eye diseases for phase Ⅰ clinical trials are in recruiting in China to evaluate future curative effect and security of stem cell-based therapies.Currently,several issues in stem cell-based eye disease therapies are still pending.We discuss the updated development of stem cell-based transplantation in ophthalmology and future researching direction in order to help ophthalmological researchers to understand the concepts and research strategies.

ObjectiveTo compare tongue positions at rest between normal occlusion people and patients with anterior cross-bite malocclusions,and to explore whether there is any abnormality in the tongue position of the anterior cross-bite malocclusions.Methods Twenty adults of normal bite (8 males and 12 females,with an average age of 23.8 years) and 20 adults of anterior cross-bite (1 1males and 9 females,with an average age of 24.6 years) were involved in this study.The position habits of tongue were investigated by a questionnaire.The tongue positions,which were enhanced by applying barium to tongue and palatal surface,were compared by cephalometric roentgenogram.Two groups were compared by t-test to determine the variation of anterior cross-bite. Results In normal occlusion group,the dorsum of tongues was sealed with all palatal surfaces except uvula site.In anterior cross bite group,tongues were far from palate,and were difficult to lift.The profile of tongue showed standing upright forward and up in normal occlusion group,while inclining back and low in anterior cross-bite group.The tops of tongue dorsum sites were at the border of soft and hard palate in normal occlusion group.While in anterior cross bite group,the tops of tongue dorsum sites were at the border of uvula and soft palate.In anterior cross-bite group,the tongue-to palate distance was bigger than that of normal occlusion group (P＜0.01).However,both length and height of the tongue had no significant differences between two groups (P＞0.05).ConclusionsIn anterior cross-bite patients,tongue positions were lower than that of normal occlusion people.

OBJECTIVETo investigate the effects of epigallocatechin gallate (EGCG)against exercise-induced fatigue in mice.

METHODSTotal 120 mice were randomly divided into three groups and tested separately. For each test, there were 30 mice subdivided into high dose (50 mg/kg . d EGCG) and low dose (10 mg/kg . d EGCG) groups as well as saline control group(1 ml/kg . d) with 10 in each. Burden swimming, running wheel endurance, stick climbing and hypoxia tolerance exercise were used to establish fatigue mice training model in three groups. And intraperitoneal injection with different doses of EGCG per day for consecutively 28 days and the mice in the control group were treated with normal saline. After the last each test, the blood lactic acid (BLA), blood urea nitrogen (BUN), blood lactate dehydrogenase (LDH), muscle glycogen (MG) and liver glycogen (LG) of each group of mice were determined.

RESULTSEGCG treatment groups(B and C)revealed a prolonged the mice survival time of burden swimming test, hypoxia tolerance, running wheel time and the ability of stick climbing(P < 0.05 or P <0.01), and increased LDH activity and MG and LG contents, reduced contents of BLA and BUN. High dose group had an obviously increase effect than lower dose group(P <0.05).

CONCLUSIONEGCG has significant effects against exercise-induced fatigue in mice.

Purpose To detect high mobility group protein A2 (HMGA2) expression in breast cancer, and to analyze its relationship with clinicopathological features and the levels of HMGA2 in different molecular subtypes of breast carcinomas. Methods An immu-nohistochemical study was undertaken for measuring the levels of HMGA2 in 58 breast carcinomas. Results ( 1 ) The expression of HMGA2 was 0, 62. 5%, 60. 0%, 100. 0% and 80. 0% in Lum A, Lum B, HER-2-OE, basal-like breast carcinoma (BLBC) and un-classification phenotype respectively ( triple negative breast cancer, 92. 3%) . High expression of HMGA2 was associated with the tri-ple-negative breast cancer (TNBC) subtypes (P<0. 01). (2) An association was identified between high expression of HMGA2, and high tumor grade, lymph node metastasis (P<0. 05), positive Ki-67, CK5/6 and EGFR (P<0. 05), negative ER and PR (P<0. 01), but no association was observed for tumor size and patients’age. Conclusion An association is identified between high ex-pression, and high tumor grade, lymph node metastasis, positive Ki-67, EGFR and CK5/6, negative ER and PR, that means a high expression of HMGA2 is associated with an adverse outcome in breast cancer. High expression of HMGA2 are associated with the TNBC subtypes. Thus recognizing HMGA2 as a rational target in TNBC. The results of the study have implications for therapeutic target iden-tification and the design of future clinical trials for TNBC.

Objective To explore the effect of tumor necrosis factor-alpha(TNF-α) blockade therapy on circulating Th17 cell percentage and serum interleukin (IL)-17 level in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Methods Twenty-seven RA and 22 AS patients were recruited, of which 14 cases from both diseases received 40 weeks TNF blockade therapy. Twenty-four healthy blood donors were used as controls. The frequencies of circulating Th17 cells were determined by flowcytometry, and serum IL-17 level were measured by enzyme linked immunosorbent assay(ELISA). Results Significantly higher baseline circulating Th17 cells were observed in active RA and AS patients compared with the healthy controls[RA 1.03%(0.66%,1.78%) vs controls 0.50%(0.43%,0.67%), Z=-3.236, P<0.01; AS(1.16±0.09)%vs controls (0.59 ±0.061)% , t =5.226, P <0.01]. Similarly, serum IL-17 level were significantly elevated in patients with both diseases compared with controls[RA(32.3±2.5) pg/ml vs controls(14.3±2.5) pg/ml, t=5.070, P<0.01; AS 28.98(23.84,36.14) pg/ml vs controls 11.84(5.33,22.12) pg/ml, Z=-4.103, P<0.01]. After TNF-α blockade therapy, serum IL-17 was significantly decreased in both diseases groups[RA △(-13.5± 5.0) pg/ml and AS △(-16.0±1.9) pg/ml]. In contrast, no significant differences were found in the frequencies of circulating Th17 cells[RA △(0.104 5±0.212 6)% and AS △(0.002 5±0.183 8)%]. Conclusion Th17 cells and IL-17 have been implicated in the pathogenesis of RA and AS. TNF-α blockade can partially inhibit the function of Th17 cells. However, it is unable to reduce the frequencies of these cells in the circulation after 40 weeks therapy, which may explain the reasons for the relapse.

Objective To compare recent curative effect between double Endobutton technique and clavicular hook plate (CHP) in patients with Tossy grade Ⅲ acromioclavicular separation.Methods One hundred and forty-nine patients with Tossy grade Ⅲ acromioclavicular dislocation were divided into control group (78 cases,treated with CHP) and observation group (71 cases,treated with double Endobutton technique) according to treatment method.The postoperative injured shoulder visual analogue score (VAS),abduction-rise activity and flexion-rise activity,Constant-Murley score and Karlsson grade were compared between 2 groups.Results All the patients successfully completed the operation,and the postoperative follow-up time was 9-40 (15.8 ± 5.2) months.The injured shoulder abduction-rise activity and flexion-rise activity postoperative 9 months in observation group were (100.9 ± 13.3)° and (131.6 ± 13.4)°,in control group were (81.4 ± 8.4)° and (96.7 ± 10.9)°; the injured shoulder VAS in observation group and control group were (2.2-± 0.8) and (3.0 ± 0.9) scores,and there were statistical differences between 2 groups (P ＜ 0.01).The Constant-Murley score in observation group and control group were (85.4 ± 6.4) and (82.5 ± 6.2) scores,the excellent and good rate of Karlsson grade in observation group and control group were 84.5％(60/71),91.0％ (71/78),and there were no statistical differences (P ＞ 0.05).Conclusions The recent curative effect of double Endobutton technique and CHP in patients with Tossy grade Ⅲ acromioclavicular separation is similar.
