AlM:To compare the efficacy and safety of latanoprost and brimonidine in the treatment of open angle glaucoma, and provide reference for rational drug use.METHODS:A total of 121 cases ( 136 eyes ) who were diagnosed as primary open angle glaucoma were selected in this study, and they were randomly divided into experimental group (62 cases, 70 eyes) and control group ( 59 cases, 66 eyes) according to different drug treatment. Patients in the control group received brimonidine eye drops twice a day, while patients in the experimental group received latanoprost eye drops once a day. The intraocular pressure, visual acuity and adverse reactions were checked of the two groups in the following 3mo.RESULTS:The intraocular pressure of patients in the control group was 18. 1 ± 1. 3mmHg, while the experimental group was 17. 0 ± 0. 9mmHg after 12wk of treatment, which were both lower than before (P<0. 05). The fluctuation of intraocular pressure in the experimental group was significantly lower than that of the control group. There was no significant difference in the LogMAR visual acuity between before and after treatment in the control group, while the LogMAR visual acuity of the experimental group was significantly improved. The control group had hyperemia, burning sensation, tearing, eyelid edema and other adverse side effects, and the experimental group had little adverse reactions. CONCLUSlON: Latanoprost can significantly reduce intraocular pressure in glaucoma patients with in the follow- up time, and reduce the impact of elevated intraocular pressure in the vision of glaucoma patients, with little adverse reaction, worthy of clinical application.

OBJECTIVETo explore relationship between volume of bone cement injection and concurrent of fracture after thoracolumbar osteoporotic vertebral fracture treated by percutaneous kyphoplasty (PKP).
METHODSFrom January 2006 to December 2008,68 patients with thoracolumbar osteoporotic vertebral fracture treated by PKP were retrospectively analyzed. Among them, 30 patients with less than 3 ml bone cement injection (mean 2.5 ml, low group), including 11 males and 19 females, with an average age of (85.0 +/- 8.5) years (ranging for 60 to 91); 38 cases with over 4 ml bone cement injection (mean 4.5 ml, large group), including 15 males and 23 females,with an average age of (86.0 +/- 9.2) years (ranging for 60 to 93). Factors of concurrent vertebral fractures were observed during follow-up.
RESULTSAll patients were followed up from 3.4 to 5.1 years with an average of 3.8 years. Thirteen patients (43.3%) co-occurred fracture in low group,among which strengthened concurrent vertebral fracture occurred in 1 case,upper and lower section adjacent vertebral fracture in 8 cases,distal segment of vertebral fracture in 4 cases; while 18 patients (47.3%) co-occurred fracture in large group,among which strengthened concurrent vertebral fracture occurred in 2 cases, upper and lower section adjacent vertebral fracture in 10 cases,distal segment of vertebral fracture in 6 cases. No significant difference between two groups (P > 0.05).
CONCLUSIONBone cement injection is not main influence factors for treating concurrent of fracture after thoracolumbar osteoporotic vertebral fracture by PKP. Concurrent fracture mainly relates with progress of osteoporosis, the volume of injection volume may appropriately over the volume of balloon.

OBJECTIVETo analyze the differential protein expression of left-sided colon cancer and right-sided colon cancer.
METHODSTissue samples of left-sided colon cancer (n=7) and right-sided colon cancer (n=7) were collected. Tissue protein was abstracted and two-dimensional gel electrophoresis (2-DE) was used to examine the gel images. Peptide mass fingerprintings (PMF) was acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and the proteins were identified by data searching with bioinformatics. Immunohistochemical SP method was used for the detection of glucose regulated protein 78 kD (GRP78) and heat shock protein 20 (HSP20) in left-sided colon cancer (n=50) and right-sided colon cancer (n=50) tissues.
RESULTSSixteen differentiating protein spots were identified. Compared with right-sided colon cancer, 10 proteins including GRP78 up-regulated and 6 proteins including HSP20 down-regulated in left-sided colon cancer. Immunohistochemical detection showed that in left and right sided colon cancer, the positive expression rate of GRP78 was 78% (39/50) and 56% (28/50) and the positive expression rate of HSP20 was 34% (17/50) and 72% (36/50), respectively, and the differences were statistically significant (both P<0.05). The positive rate of GRP78 was associated with tumor differentiation, infiltration layer, TNM staging, lymph node metastasis, and liver metastasis, while the positive rate of HSP20 was associated with tumor gross morphology, TNM staging, and lymph node metastasis (P<0.05).
CONCLUSIONSThere are differentially expressed proteins between left-sided colon cancer and right-sided colon cancer, especially for GRP78 and HSP20, which may be the cause leading to the biological differences between left-sided and right-sided colon cancer.

Objective To explore the relationship between receptor of advanced glycaton end products(RAGE)gene Gly82Ser polymorphism and patients with transient ischemia attack(TIA).Methods The Gly82Ser gene at the position of RAGE gene exon 3 was identified by a polymerase chain reaction- restriction fragment length polymorphism(PCR-RFLP)method in 70 cases of TIA & Diabetes(DM), 60 of simply TIA and 66 healthy control subjects.Results The genotypes of RAGE gene Gly82Ser identified were GG, GS and SS.The frequencies of RAGE gene Gly82Ser GS heterozygous genotype of TIA & DM and control were respectively 62.9% and 43.9%, significantly higher in TIA & DM patients than in control subjects(OR 2.036, 95% CI 1.021--4.062, P=0.042), however no significant difference was found between simply TIA and control(53.3% vs 43.9%, OR 1.299,95% CI O.644--2.618, P=0.465). Significant difference of the frequency of S allele was found neither between TIA & control and control(being 34.3% and 26.5%, respectively, OR 1.446,95% CI 0.859--2.434, P=0.164), nor between simple TIA and control(28.3% vs 26.5%, OR 1.096,95%CI 0.630--1.907, P=0.746).Conclusions RAGE gene Gly82Ser GS heterozygous genotype may be associated with TIA & DM patients.RAGE gene Gly82Ser polymorphism is a risky factor for TIA & DM patients, but not for TIA patients.
