Despite the knowledge of many genetic alterations present in osteosarcoma, the complexity of this disease precludes placing its biology into a simple conceptual framework. Cytotoxic T-lymphocyte antigen-4 (CTLA-4) plays important roles in downregulating T-cell activation, thereby attenuating anti-tumor responses and increasing cancer susceptibility. Polymorphisms in the CTLA-4 gene are associated with different autoimmune diseases and cancers. The current study evaluated the association of four CTLA-4 gene mutations,-1661A/G (rs4553808),-318C/T (rs5742909), +49G/A (rs231775), and CT60A/G (rs3087243), with osteosarcoma in the Chinese population. CTLA-4 polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism in 267 osteosarcoma patients and 282 age-matched healthy controls. Results showed that the CTLA-4 gene +49 AA genotype, +49 A allele, and GTAG haplotype were significantly more frequent in osteosarcoma patients than in controls (odds ratio [OR] 2.20, 95% confidence interval [CI] 1.23-2.95, p = 0.007; OR 1.32, 95% CI 1.03-1.69, p = 0.029, and OR = 1.47, 95% CI 1.03-2.09, p = 0.033, respectively). The CTLA-4 +49G/A polymorphism and GTAG haplotype are associated with increased risk of osteosarcoma. © 2011 Mary Ann Liebert, Inc.

Inflammation | Year: 2013

T cell immunoglobulin- and mucin-domain-containing molecule 3 (TIM-3) has been established as a negative regulatory molecule and plays a critical role in inflammatory diseases such as rheumatoid arthritis, hepatitis B and C, and human immunodeficiency virus (HIV)-related inflammation. Recent studies have shown that chronic inflammation may greatly affect the pathogenesis of non-Hodgkin lymphomas (NHL). The aim of this study was to investigate whether polymorphisms in the TIM-3 gene were associated with susceptibility to non-NHL and HIV-related NHL. Three polymorphisms in TIM-3 gene (-1516G/T, -574G/T, and +4259T/G) were identified by polymerase chain reaction-restriction fragment length polymorphism in 434 NHL patients, 62 HIV-related NHL cases, and 512 healthy controls. Results showed that the prevalence of -574GT genotype and +4259TG genotype were significantly increased in the NHL cases than in controls (odds ratio (OR) = 2.72, 95 % confidence interval (CI) = 1.50-4.92, p = 0.0006 and OR = 2.59, 95 % CI = 1.49-4.49, p = 0.0005, respectively). The -1516G/T polymorphism did not reveal significant difference between patients and healthy controls. When analyzing the TIM-3 polymorphisms in HIV-related NHL patients, data showed that HIV+ NHL patients had higher prevalence of -574GT or +4259TG genotypes than those cases without HIV infection (OR = 3.48, 95 % CI = 1.67-7.28, p = 0.0005 and OR = 2.92, 95 % CI = 1.42-6.01, p = 0.0026, respectively). These results suggested polymorphisms in TIM-3 gene could be new risk factors for NHL as well as HIV-related NHL and suggested a possible role of the inflammatory factor in these diseases. © 2013 Springer Science+Business Media New York.

Background To evaluate the efficacy of flow-diverting devices (FDDs) used in the treatment for intracranial aneurysms (IAs), we performed a meta-analysis of published literature on FDDs. Methods A systematic electronic database search was conducted using MEDLINE, PubMed, Springer, and EBSCO for all accessible articles on FDDs published until December 2014. Abstracts, full-text manuscripts, and the reference lists of retrieved articles were analyzed. Random effects meta-analysis was used to pool the occlusion rate outcomes across studies. Results Fifty-nine studies containing efficacy data on 2263 patients with more than 2493 treated aneurysms were included in the analysis. The overall complete occlusion rate was 82.5% (95% CI, 78.8%-86%) across studies. The success rate of FDD implantation was 97.4% (95% CI, 95.4%-99.4%). The occlusion rate for anterior circulation aneurysms was 83.3% (95% CI, 71.2%-95.4%); with regard to complete occlusion, the odds ratio for anterior circulation aneurysms was significantly higher than that of posterior circulation IAs (odds ratio, 1.93; 95% CI, 1.00-3.73). Conclusions FDDs have high technical success rates in the management of IAs. Additional studies on well-designed, multicenter, randomized controlled trials will be required to validate the findings of the present study and to identify the best therapeutic strategy for IAs depending on their size, location, and characteristics. © 2016 Elsevier Inc.

The binding properties of new complexes [Ru(L)2(3-tppp)]2 + (L = bpy, phen) towards two different forms of the human telomeric G-quadruplexes DNA have been investigated by UV–Vis spectroscopy, fluorescent indicator displacement (FID) assays, fluorescence resonance energy transfer (FRET) melting assays and molecular docking studies. The molecular docking studies indicated that both complexes interacted with 22AG with the stoichiometric ratio of 1:1, but the two complexes showed different G-quadruplexed DNA binding affinity. Complex 2 bound to the G-quadruplexes DNA more tightly than complex 1 did. Moreover, the FRET melting assay revealed that both complexes could be potential stabilizers for G-quadruplex architectures. These studies are useful not only for better understanding of the interaction between the target G-quadruplexes DNA and metal complexes but also valuable in defining the best strategy to prepare metal complexes as potential anticancer drugs. © 2016 Elsevier B.V.

Paeoniflorin (PF), a monoterpene glycoside isolated from the aqueous extract of Radix Paeoniae Alba, is widely used in Traditional Chinese Medicine (TCM) for the treatment of neurodegenerative disorders such as Alzheimer's disease (AD) and Parkinson's disease (PD). In this study, we investigated the protective mechanism of PF on glutamate-induced neurotoxicity in cultured rat pheochromocytoma (PC12) cells. PC12 cells were cultured in vitro, cell viability was assessed by MTT assay, cell apoptosis as well as mitochondrial membrane potential (MMP) were detected by flow cytometric analysis and the expression profiles of apoptosis-related proteins including Bcl-2 and Bax were investigated by western blot. The results showed that PF could protect PC12 cells against glutamate-induced injury in a concentration-dependent manner and the mechanism of neuroprotective effect of PF was closely associated with up-regulation of Bcl-2 and down-regulation of Bax. It demonstrated that PF has neuroprotective effect on glutamate-induced apoptosis in PC12 cells via regulating mitochondrial membrane potential and Bcl-2/ Bax signal pathway.

Objective: To observe the therapeutic effect of preconditioning acupuncture (PA) on the treatment of primary dysmenorrhea. Methods: Eighty patients suffered from primary dysmenorrhea were randomly assigned on the ratio of 1:1:2 into three groups, 20 in Group A, 20 in Group B, and 40 in Group C. Group A and B were treated with PA and immediate acupuncture (IA), respectively, while Group C received no acupuncture treatment and be taken as a blank control. The treatment was lasted for three menstrual cycles. The therapeutic effects were observed and compared. Results: Comparing the scores of the symptoms in the different groups, the therapeutic effect in different groups showed that the symptom scores in Group A at the second and third cycle of treatment, as well as at the first and third cycle of follow-up, were significantly lower than the scores in Group B, respectively (P<0.05 or P<0.01), and the duration of symptoms was shorter in Group A than in Group B at the third cycle of treatment and the first and third cycle of follow-up (P<0.05). Symptom scores in Groups A and B in the treatment and follow-up periods were all lowered as compared to those before treatment (P<0.01), and the scores were also lower than those in Group C measured at corresponding times (P<0.01). Conclusion: The therapeutic effect of PA, either the short-term or the long-term effect, was superior to that of IA in treating dysmenorrhea. ©The Chinese Journal of Integrated Traditional and Western Medicine Press and Springer-Verlag 2011.

Objective. To investigate the relationship between serum procalcitonin (PCT) levels and prognosis in children with bacterial meningitis. Methods. Eighty-two child patients were included in this prospective study. The diagnosis of meningitis was based on clinical features and cerebrospinal fluid findings. PCT levels were measured with a specific immunoluminometric assay. Results. (a) Patients with bacterial meningitis had significantly higher serum PCT than those with viral meningitis. (b) The PCT levels of patients with severe sepsis or septic shock were significantly higher than those who had no or mild sepsis. (c) PCT levels decreased significantly in patients who had good curative effect, whereas PCT levels did not changed in patients who had no curative effect. (d) The PCT levels were significantly higher in those who died than those who survived. Conclusions. Serum PCT is related to the severity of disease in children with bacterial meningitis. A fall in PCT after treatment may have favorable prognostic significance. © 2015 SAGE Publications.

Fed-batch culture is often used in industry, and dissolved oxygen (DO) concentration control is important in fermentation process control. DO control is often applied by using feedback (FB) control strategy. But, feedforward-feedback (FF-FB) control has the advantage in dealing with the time-varying characteristics resulting from cell growth during the fermentation process. Mathematical modeling and computer simulation is a useful tool in the analysis of the control system. In this paper, we model and simulate the FF-FB DO control and FB substrate control of repeated fed-batch culture process. The results show the feasibility of the control strategy and are useful for control system development and process analyses and optimization. © 2016, UK Simulation Society. All rights reserved.
