0.05).Frequencies of P12A12 genotype and A12 allele in DN group were significantly decreased respectively,when compared with DN-0 group(for P12A12 genotype,9.1% vs 18.1%,P=0.034,OR=0.453;for A12 allele,4.5% vs 9.0%,P=0.041,OR=0.479). Conclusion The observations suggest that P12A polymorphism of PPAR?2 gene is associated with Chinese type 2 diabetic nephropathy,and A12 allele may protect the development of diabetic nephropathy in type 2 diabetic patients of Chinese.

Objective To explore the relationship between Arg913Gln(G→A) polymorphism of solute carrier family 12 member 3 (SLC12A3) gene and diabetic nephropathy (DN) in type 2 diabetes mellitus (T2DM) in Han population of Shanghai. Methods Two hundred and fifty-eight Han ethnic people in Shanghai with T2DM (T2DM group) were divided into non-DN group (DN0 group, n=95) and DN group (n=163) according to 24 h urine albumin excretion rate (AER), and those in DN group were subdivided into microalbuminuria group (DN1 group, n=95) and macroalbuminuria group (DN2 group, n=68). Besides, 82 people with normal results of oral glucose tolerance test (OGTT), without diabetes mellitus and nephropathy were served as controls. PCR-sequencing was used to detect the genotypes of Arg913Gln polymorphism of SLC12A3 gene. Genotypic and allelic frequencies and clinical characteristics were compared among groups. Results Three genotypes (GG, GA and AA) were detected. The frequencies of GA+AA genotype and A allele in T2DM group were higher than those in control group, while there was no significant difference between groups (P>0.05). There was no significant difference in genotypic or allelic frequencies among subgroups of T2DM group (P>0.05). The level of triglyeeride (TG), AER, level of fasting insulin (FINS) and HOMA-IR in patients with GA+AA genotype were significantly higher than those in patients with GG genotype in T2DM group (P<0.05). Conclusion Arg913Gln(G→A) polymorphism of SLC12A3 gene is not significantly associated with T2DM and DN in Han population of Shanghai. The AER of people with GA+AA genotype is significantly higher than that with GG genotype. Arg913Gln (G→A) polymorphism of SLC12A3 gene may predict the risk of increase of albuminuria in patients with T2DM in Han population of Shanghai.

Objective To investigate the effect of proteasome inhibitor MG132 on the proliferation of human lens epithelial cells SRA01/04. Methods The SRA01/04 cells were treated with MG132 by different concentrations (0, 0. 1, 0. 5, 1. 0, 2. 5, 5.0, 10. 0μmol/L) for 36 hours. The cell viability in all groups was determined using methylthiazoltetrazolium (MTT) test. The effect of MG132 on the apoptosis and regulation of cell cycle about SRA01/04 cells were detected by flow cytometry (FCM). The SRA01/04 cells treated with MG132 were observed after Annexin V/FITC-PI staining by fluorescence microscope. Results The inhibitory effect of MG132 on SRA01/04 cells proliferation was enhanced with the increase of MG132 concentration. The 50% inhibiting concentration ( IC50 ) of MG132 was 2. 50μmol/L after SRA01/04 cells were treated with MG132 for 36 hours. The apoptosis index of the cells treated by MG132 at 2. 5μmol/L and 5 μmol/L for 36 hours was 6. 55 ± 0. 35% and 13.75 ± 3.18%, and 0. 75 ± 0. 21% for 5.0μmol/L for 36 hours in control group. After cells were treated with MG132 for 48h, the percentages of cells at G0/G1 phase were (42. 57 ± 0. 64) %, (73.42 ± 3.10) %, ( 80. 95 ± 3.83 ) % 0, 2. 5,5.0 μmol/Lgroups respectively, and those at S phase were (49. 44±1.36)%, ( 17. 40 ± 1.50)%, ( 19. 57 ± 1.29)%.Annexin V/FITC-PI staining was used, and MG132 was found to result to apoptosis. Conclusions MG132 could inhibit the proliferation of SRA01/04 cells by the effect of inducing apoptosis and regulation of cell cycle. The proteasome inhibitor-might play a key role in the prevention of posterior capsular opacification.

Objective To study the clinical value of ~(18)F-fluorodeoxyglucose(~(18)F-FDG) coincidence SPECT imaging in the therapy of malignant lymphoma. Methods Serial ~(18)F-FDG SPECT imaging were performed on 42 patients with malignant lymphoma before and after treatment.The results were compared with other conventional imaging.Patients were divided into two groups. Twenty-seven new-diagnosed patients(group Ⅰ) and 15 operated patients(group Ⅱ) had ~(18)F-FDG imaging pre-and post-chemotherapy. Results(In group Ⅰ,) 15 cases(achieved) clinical remission,five cases relapsed and one case progressed.In group Ⅱ,tumor residues were detected in four patients,and one patient relapsed. Conclusion Serial ~(18)F-FDG imaging during treatment is very useful for therapeutic evaluation in malignant lymphoma.

Objective To investigate the correlation between ADAM33 T1, S2 gene polymorphism and Bronchial asthma risk in china. Methods We retrived the relevant published studies about ADAM33 T1, S2 gene polymorphism and bronchial asthma risk. Then we divided the population into Chinese and other Asian population. Odds ratio (OR) of Case group and control group was selected as the effect index. Stata 11.0 software was used to calculate heterogeneity test, ORs and 95%CI of two areas, and gave the forest plot and funnel plot of meta results. Results A total of 27 studies were included in this analysis,18 studies in ADAM33 T1 site were 3881 cases in case group, and 3780 cases in control group;and 14 studies in ADAM33 S2 site were 3222 cases in case group, and 3513 cases in control group. Additive model, dominant model, recessive model of ADAM33 T1 in Chinese had association with the susceptibility of bronchial asthma. The results were OR=1.488, 95% CI:1.002-2.167 in Additive model, OR=1.619, 95%CI:1.059-2.475 in dominant model;OR=2.523, 95%CI:1.910-3.333 in recessive model. Three models of ADAM33 T1 in other Asian country had no association with the susceptibility of Bronchial Asthma. Three gene model of ADAM33 S2 in Asian had no association with bronchial asthma susceptibility. Except ADAM33 T1 polymorphism in recessive model, other mode of T1, S2 had no publication bias in Chinese population. Conclusion There are association between ADAM33 T1 gene polymorphism and bronchial asthma, but ADAM33 S2 gene polymorphism and bronchial asthma have no association in Chinese population.

BACKGROUND:There are many ways for surgical treatment of distal radius fractures. Both volar locking plates and Kirschner wires are common methods. Doctors have considerable flexibility in the choice of the ways of fixation, but both at home and abroad there is no comparison between the effects of the two operations for treating distal radius fractures. OBJECTIVE:To systematicaly review the differences in effectiveness and safety of volar locking plates versusKirschner wires for distal radial fracture. METHODS:Databases such as CBM, CNKI, VIP, PubMed and Cochrane Library were electronicaly searched.Chinese Journal of Orthopaedics,Chinese Journal of Orthopaedic Trauma,Chinese Journal of Trauma andJournal of Practical Orthopaedics were searched by hand. In strict accordance with inclusion and exclusion criteria, articles were screened. Methodological quality of included studies was evaluated according to Cochrane Handbook. Data were extracted, and then analyzed with RevMan 5.2 software. RESULTS AND CONCLUSION:Nine randomized controled trials were included. Meta-analysis results demonstrated that upper limb function scores were better in the volar locking plate group than in the Kirschner wire group [MD=-4.55(-7.89,-1.21),P=0.008] at 3 months of folow-up and [MD=-3.13(-6.08,-0.18),P=0.004] at 12 months. The incidence of infection was lower in the volar locking plate group than in the Kirschner wire group [OR= 0.42(0.23, 0.79),P=0.007]. No significant difference in incidence of complex regional pain syndrome [OR=0.28(0.05, 1.38),P=0.12], incidence of carpal tunnel syndrome [OR=0.75(0.20, 2.76),P=0.66] and tendon injury [OR= 1.66(0.51, 5.41),P=0.64] was detected between the volar locking plate group and Kirschner wire group. These results indicated that compared with the Kirschner wire, volar locking plate fixation for the repair of distal radial fracture is safe and effective. In the permission of economic circumstances, it is suggested that elder osteoporosis patients with distal radial fracture should receive plate fixation.

0.05). Conclusion Preproghrelin-Leu72Met is not significantly associated with T2DM and DN in Shanghai Han populations,while T2DM with AA genotype is characterized by significant declination in urine microalbumin when compared with CA and CC genotypes.Leu72Met polymorphism(C→A)may postpone the development of microalbuminuria in T2DM subjects.

To investigate the principal metabolites of 1-(1-(6-methoxyl-2-naphthyl) ethyl)-2-(4-nitrobenzyl)-6,7-dimethoxyl-1,2,3,4-tetrahydroisoquinoline hydrobromide (code designation: P91024) in rats after ig administration by LC-MS/MS, the phase I metabolites were discovered by comparing the fullscan and SIM chromatograms of the test samples with the corresponding blanks. The structures of phase I metabolites were identified by ESI-MS spectra and the product spectra of the corresponding adduct ions. The phase II metabolites were identified in the test samples after the phase I metabolites were completely removed with solvent extraction and then treated with glucuronidase for enzymolysis of phase II glucuronide conjugates and the hydrolysates. Two phase I metabolites of P91024 were identified in rat feces, one phase I and five phase II in bile, one phase I and three phase II in urine, and four phase I and one phase II in plasma. Their structures were elucidated, separately. P91024 was extensively metabolized in rat. The metabolites can be easily screened and identified by LC-MS/MS method.
