    ABSTRACT: The ideal therapeutic agent for treatment of osteoarthritis (OA) should have not only potent anti-inflammatory effect but also favorable biological properties to restore cartilage function. Gallic acid (GA) and its derivatives are anti-inflammatory agents reported to have an effect on OA [1]. However, GA has much weaker antioxidant effects and inferior bioactivity compared with its derivatives. We modified GA with the introduction of sulfonamide to synthesize a novel sulfonamido-based gallate named sodium salt of 3,4,5-trihydroxy-N-[4-(thiazol-2-ylsulfamoyl)-phenyl]-benzamide (SZNTC) and analyzed its chondro-protective and pharmacological effects. Comparison of SZNTC with GA and sulfathiazole sodium (ST-Na) was also performed. Results showed that SZNTC could effectively inhibit the Interleukin-1 (IL-1)-mediated induction of metalloproteinase-1 (MMP-1) and MMP-3 and could induce the expression of tissue inhibitor of metalloproteinase-1 (TIMP-1), which demonstrated ability to reduce the progression of OA. SZNTC can also exert chondro-protective effects by promoting cell proliferation and maintaining the phenotype of articular chondrocytes, as evidenced by improved cell growth, enhanced synthesis of cartilage specific markers such as aggrecan, collagen II and Sox9. Expression of the collagen I gene was effectively down-regulated, revealing the inhibition of chondrocytes dedifferentiation by SZNTC. Hypertrophy that may lead to chondrocyte ossification was also undetectable in SZNTC groups. The recommended dose of SZNTC ranges from 3.91 μg/ml to 15.64 μg/ml, among which the most profound response was observed with 7.82 μg/ml. In contrast, its source products of GA and ST-Na have a weak effect in the bioactivity of chondrocytes, which indicated the significance of this modification. This study revealed SZNTC as a promising novel agent in the treatment of chondral and osteochondral lesions.

    ABSTRACT: To compare outcomes between mobile-bearing (MB) and fixed-bearing (FB) in bilateral total knee replacements. The MEDLINE, EMBASE and Cochrane Library databases were searched. Randomized controlled trials of bilateral total knee arthroplasty with one of each design implanted were identified. Weighted mean differences (WMDs) and pooled risk ratios (RRs) were calculated using fixed- or random-effects models. Twelve studies were identified with a total of 807 patients and 1614 knees. All RCTs were of high quality with a low risk of bias. No statistical difference was found between MB and FB at 2- to 5-year follow-up in terms of America Knee Society score (WMD: -1.29, 95% CI: -5.65 to 3.06), pain score (WMD: -3.26, 95% CI: -10.45 to 3.93), range of motion (WMD: -4.16, 95% CI: -9.97 to 1.66), reoperation (RR: 1.00, 95% CI: 0.28 to 3.60), and radiolucent lines (RR: 1.51, 95% CI: 0.70 to 3.24). The results were similar at 1-, 5- to 8-, or >8-year follow-up. Patient's satisfaction (RR: 0.85, 95% CI: 0.54 to 1.34), and complication (≤2-year, RR: 0.55, 95% CI: 0.29 to 1.04; >2-year, RR: 1.0, 95% CI=0.73 to 1.38) also showed no difference between two groups. Based on this meta-analysis we are unable to detect the superiority of MB as compared to FB. More randomized trials with a larger sample size and longer follow-up are needed to evaluate these two kinds of prosthesis. Therapeutic Level II.

    ABSTRACT: Myeloperoxidase (MPO) is a metabolic/oxidative lysosomal enzyme secreted by reactive neutrophils at the sites of inflamed organs and tissues during phagocytosis. MPO has been either directly or indirectly linked to neoplasia, which is a well-established risk factor for many types of cancer. A large number of studies have reported the role of MPO G-463A polymorphism regarding breast-cancer risk. However, the published findings are inconsistent. Therefore, we conducted a meta-analysis to determine more precise estimations for the relationship. Eligible studies were identified by searching several electronic databases for relevant reports published before June 2012. According to the inclusion criteria and exclusion criteria, a total of five eligible studies were included in the pooled analyses. When the five eligible studies concerning MPO G-463A polymorphism were pooled into this meta-analysis, there was no evidence found for a significant association between MPO G-463A polymorphism and breast-cancer risk in any genetic model. We also categorized by ethnicity (Caucasian or Asian) for subgroup analysis; according to this subgroup analysis, we found no significant association between MPO G-463A polymorphism and breast-cancer risk in any genetic model. However, in the stratified analysis for the premenopausal group, women carrying the AA genotype were found to have a significantly reduced risk (OR = 0.56, 95% CI 0.34-0.94, p = 0.027). Under the recessive model, there was a significant association between MPO G-463A polymorphism and breast-cancer risk (OR = 0.57, 95% CI 0.34-0.93, p = 0.025). We conclude that MPO-G463A polymorphism might not be a good predictor of breast-cancer risk, though menopausal status modified women's risk of developing breast cancer.

    ABSTRACT: The polymorphism of the plasminogen activator inhibitor-1 (PAI-1) 4G/5G gene has been correlated with susceptibility to osteonecrosis of the femoral head (ONFH), but study results are controversial. The aim of this study was to derive a more precise estimation of the relationship between the PAI-1 4G/5G Gene polymorphism and ONFH by performing a meta-analysis. The meta-analysis was based on five eligible case-control studies involving 419 cases and 969 controls and summarized data indicating the association between PAI-1 polymorphism and risk of osteonecrosis of the femoral head. Odds ratios (OR) with 95% confidence intervals (95% CI) were used to assess the strength of this association in the random-effects model or fixed-effects model. A significant association between PAI-1 4G/5G polymorphism and ONFH susceptibility was observed for 4G4G+4G5G vs. 5G5G (OR=1.766, 95% CI 1.279-2.437, P=0.001), 4G/4G vs. 4G/5G+5G/5G (OR=2.050, 95% CI 1.581-2.657, P=0.000), 4G/4G vs. 5G/5G (OR=2.553, 95% CI 1.345-4.846, P=0.004), and 4G vs. 5G (OR=1.758, 95% CI 1.236-2.500, P=0.002). No significant association between PAI-1 4G/5G polymorphism and ONFH susceptibility was observed for 4G/5G vs. 5G/5G (OR=1.327, 95% CI 0.939-1.877, P=0.109). This meta-analysis suggested that 4G/5G polymorphism of the PAI-1 gene was a risk factor for ONFH. This study also suggests that the PAI-1 4G4G genotype may indicate a risk for ONFH.

    ABSTRACT: BACKGROUND: The X-ray repair cross-complementation group 1 (XRCC1) protein plays an important role in base excision repair. AIM: To elucidate the role of XRCC1 Arg399Gln, Arg194Trp and Arg280His genotypes in esophageal cancer risk, all available studies were considered in the present meta-analysis. METHODS: Eligible studies were identified by searching several electronic databases for relevant reports published before June 2012. RESULTS: According to the inclusion criteria and exclusion criteria, a total of 21 eligible studies were included in the pooled analyses. Among the 21 studies, 18 focused on Arg399Gln polymorphism, 11 described the Arg194Trp, and 4 articles investigated on Arg280His. Our analysis suggested that there was no evidence of significant association between XRCC1 Arg399Gln polymorphism and esophageal cancer risk in any genetic model. In the stratified analysis by ethnicity for Arg399Gln polymorphism and esophageal cancer, the results showed that Arg399Gln polymorphism was not associated with esophageal cancer risk. Only 4 studies analyzed the relationship between XRCC1 Arg280His polymorphism and the risk of esophageal cancer. The Arg/His and His/His genotypes were not significantly associated with increased risk of EC. A similar negative association was maintained in dominant and recessive models. However, for XRCC1 Arg194Trp polymorphism, our study showed individuals carrying the variant genotype Trp/Trp had a significant increased risk of esophageal cancer (OR = 1.295, 95 % CI 1.053-1.591, P = 0.014). In addition, increased associations were found in recessive model (OR = 1.332, 95 % CI 1.093-1.624, P = 0.005). CONCLUSIONS: Our meta-analysis suggested that Arg194Trp Trp allele might act as a risk allele in its association with esophageal cancer.

    ABSTRACT: Interleukin-16 (IL16) as a multifunctional cytokine, plays a key role in inflammatory and autoimmune diseases as well as tumour growth and progression. Recently, genetic polymorphisms of IL16 have been reported to be associated with susceptibility to a range of cancers. This study was undertaken to investigate the IL16 gene polymorphisms and determine whether these genetic factors are related to the occurrence of hepatocellular carcinoma (HCC) in a Chinese population. We analyzed three polymorphisms of the IL16 gene (rs11556218T/G, rs4072111C/T and rs4778889T/C) in 206 patients with HBV-related HCC, 270 chronic hepatitis B patients and 264 healthy controls, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method and DNA sequencing technology. IL16 polymorphisms were not associated with risk of HCC when compared with healthy controls. However, IL16 polymorphisms were significantly associated with susceptibility to HBV-related HCC when using chronic hepatitis B patients as controls. The rs11556218T/G TG and GG genotypes were associated with significantly increased risk of HBV-related HCC compared with the TT genotype (OR = 1.96 and OR = 3.33). The data also revealed that subjects with the G allele appeared to have higher susceptibility to HBV-related HCC than those with the T allele (OR = 2.10). Under the dominant model genotype TG+GG appeared to be associated with an increased risk of HBV-related HCC (OR = 2.18). The rs4072111C/T TT genotype was associated with a significantly increased risk of HBV-related HCC compared with the CC genotype (OR = 6.67). Polymorphisms of the IL16 gene were significantly associated with susceptibility to chronic hepatitis B when using healthy subjects as controls. The rs11556218T/G TG and GG genotypes were associated with significantly decreased risk of chronic hepatitis B compared with the TT genotype (OR = 0.49 and OR = 0.29). The data also revealed that subjects with the G allele appeared to have lower susceptibility to chronic hepatitis B than those with the T allele (OR = 0.46). Under the dominant model genotype TG + GG appeared to have lower susceptibility to chronic hepatitis B (OR = 0.44). This study showed that the genotypes and allele of IL16 SNPs were associated with chronic HBV infection and HCC. However, further investigation with a larger sample size and haplotype analysis with other SNPs may be required to validate the genetic effects of the IL16 polymorphisms on chronic HBV infection and HCC.

    ABSTRACT: Whether high-flexion prostheses are superior to conventional prostheses after total knee arthroplasty (TKA) remains controversial. Therefore, this meta-analysis was conducted to evaluate the effects of these 2 different designs. After a comprehensive search, 11 trials with 1204 knees were eligible for data extraction and pooled analysis. The results demonstrated that there were no differences in range of motion of high-flexion posterior-stabilized vs standard posterior-stabilized TKA (weighted mean improvement, 0.93°; 95% confidence intervals, -0.75° to 2.60°; P = .28), range of motion of high-flexion cruciate-retaining vs cruciate-retaining TKA (2.06°; 0.06°-4.17°; P = .06), weight-bearing flexion (2.05°; 0.99°-5.08°; P = .19), Knee Society Scores (1.59 points; 0.42-3.60 points; P = .12), and Hospital for Special Surgery Scores (0.84 points; 0.37-2.04 points; P = .17) with at least 1-year follow-up. No infection, loosening, and osteolysis were found. The current evidences cannot confirm that high-flexion prostheses are superior to conventional prostheses.

    ABSTRACT: Conventional tests are not always helpful in making a diagnosis of rheumatoid arthritis (RA). This study aimed to comprehensively and quantitatively summarize the evidence on the accuracy of anti-mutated citrullinated vimentin (MCV) assay in the diagnosis of RA. A comprehensive meta-review of data on the accuracy of MCV concentrations in the diagnosis of RA were carried out from 16 published studies. Furthermore, receiver operating characteristic curves were used to summarize the overall test performance. The summary estimates for MCV in the diagnosis of RA were: sensitivity 0.77 [95% confidence interval (CI) 0.75-0.78], specificity 0.89 (95% CI 0.87-0.90), positive likelihood ratio (LR+) 7.24 (95% CI 5.60-9.36), negative likelihood ratio (LR-) 0.28 (95% CI 0.23-0.34) and diagnostic odds ratio 29.66 (95% CI 21.09-41.71). The area under the summary receiver operating characteristic curves was 0.92. Data from meta-analysis suggest the accuracy of MCV assay in the diagnosis of RA is high, but ultimately clinician must consider the results of MCV tests combing with other conventional examinations and the clinical feature.

    ABSTRACT: No satisfactory biomarkers are currently available to screen for nasopharyngeal carcinoma (NPC). We have developed and evaluated surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS) for detection and analysis of multiple proteins for distinguishing individuals with NPC from control individuals. A preliminary learning set and a classification tree of spectra derived from 24 patients with NPC and a group of 24 noncancer controls were used to develop a proteomic model that discriminated cancer from noncancer effectively. Then, the validity of the classification tree was challenged with a blind test set, which included another 20 patients with NPC and 12 noncancer controls. A panel of 3 biomarkers ranging m/z 3-20 k was selected to establish Decision Tree model by BPS with sensitivity of 91.66% and specificity of 95.83%. The ability to detect NPC patients was evaluated, a sensitivity of 95.0% and specificity of 83.33% were validated in blind testing set. This high-flux proteomic classification system will provide a highly accurate and innovative approach for the detection/diagnosis of NPC.
