Objectives To investigate whether genetic variants in methylenetetrahydrofolate reductase (MTHFR) and methylenetetrahydrofolate dehydrogenase (MTHFD) genes are associated with risk of congenital cardiac disease.Background Accumulative evidence suggests that hyperhomocysteinaemia is associated with risk of congenital cardiac disease. Inherited polymorphisms in key folate metabolic pathway genes, MTHFR and MTHFD, may influence the efficiency of folate metabolism and plasma level of homocysteine.Methods A two-stage case-control study of congenital cardiac disease was conducted by genotyping MTHFR c.1793G>A and four other variants - MTHFR c.677C>T, c.1298A>C, and MTHFD c.1958G>A, c.401C>T - in a Chinese population consisting of 1033 congenital cardiac disease patients and 1067 non-congenital cardiac disease patients.Results The variant genotypes of MTHFR c.1793GA/AA were associated with a significantly decreased risk of congenital cardiac disease in two stages combined, with an adjusted odds ratio of 0.67 and a 95% confidence interval of 0.54-0.84 (p = 0.0004). In comparison with wild-type homozygote c.1793GG, the effect was significant in isolated perimembranous ventricular septal defect patients with an adjusted odds ratio of 0.60 and a 95% confidence interval of 0.43-0.83 (p = 0.0003).Conclusion These findings indicate that MTHFR c.1793G>A may have a role in susceptibility to sporadic congenital cardiac disease.

Objective: To evaluate the efficacy and safety of combined treatment with angiotensin II receptor blocker (ARB) and angiotensin converting enzyme inhibitor (ACEI) on diabetic kidney disease. Methods: Randomized controlled trials (RCTs) were identified from CoChrane library, PubMed, EMbase, CNKI and VIP. Eleven RCTs involving 602 patients were included and analyzed with Rev Man 5.1 software. Results: Compared with ACEI alone, combined treatment with ARB and ACEI was more effective on decreasing 24 h albuminuria, systolic pressure, average 24 h systolic pressure, diastolic pressure, and average 24 h diastolic pressure but with a high level of serum potassium. Compared with ARB alone, combined treatment with ARB and ACEI was more effective on decreasing systolic pressure and diastolic pressure. Compared with ACEI or ARB alone, we didn't get a definite conclusion that whether combined treatment with ARB and ACEI was more effective on decreasing 24 h proteinuria. Conclusion: Based on this Meta analysis, combined treatment with ARB and ACEI is safer and has positive effect on diabetic kidney disease. However, small sample size and low methodological quality appeared in most of the trials included in this systematic review. Therefore, available evidence is insufficient to recommend a routine clinical application of combined treatment with ARB and ACEI on diabetic kidney disease. Source

The glucagon-like peptide-1 is secreted by intestinal L cells in response to nutrient ingestion. It regulates the secretion and sensitivity of insulin while suppressing glucagon secretion and decreasing postprandial glucose levels. It also improves beta-cell proliferation and prevents beta-cell apoptosis induced by cytotoxic agents. Additionally, glucagon-like peptide-1 delays gastric emptying and suppresses appetite. The impaired secretion of glucagon-like peptide-1 has negative influence on diabetes, hyperlipidemia, and insulin resistance related diseases. Thus, glucagon-like peptide-1-based therapies (glucagon-like peptide-1 receptor agonists and dipeptidyl peptidase-4 inhibitors) are now well accepted in the management of type 2 diabetes. The levels of glucagon-like peptide-1 are influenced by multiple factors including a variety of nutrients. The component of a meal acts as potent stimulants of glucagon-like peptide-1 secretion. The levels of its secretion change with the intake of different nutrients. Some drugs also have influence on GLP-1 secretion. Bariatric surgery may improve metabolism through the action on GLP-1 levels. In recent years, there has been a great interest in developing effective methods to regulate glucagon-like peptide-1 secretion. This review summarizes the literature on glucagon-like peptide-1 and related factors affecting its levels. © 2015 XingChun Wang et al. Source

Primary spinal melanoma is a rare lesion, which occurs throughout the cranial and spinal regions, however, is primarily observed in the middle or lower thoracic spine. The clinical features of primary spinal melanoma are complex and unspecific, resulting in a high misdiagnosis rate. In the present case report, a rare case of spinal melanoma exhibiting the dural tail sign and mimicking spinal meningioma is reported. The initial diagnosis, using magnetic resonance imaging (MRI), was unclear. Thus, melanin-containing tumors and spinal meningioma should have been considered in the differential diagnosis. The tumor was completely resected using a standard posterior midline approach, which was followed by chemotherapy. Subsequent to the surgery, the patient was discharged with improved motor capacity and a follow-up MRI scan showed no recurrence after six months. The present study demonstrates that it is critical for neurosurgeons to focus on increasing the accuracy of initial diagnoses in order to make informed decisions regarding the requirement for surgical resection. The present case report presents the clinical, radiological and pathological features of primary extramedullary spinal melanoma mimicking spinal meningioma to emphasize the importance of early identification and diagnosis.

Purpose: Several molecular epidemiological studies have investigated the association between OPN rs11730582 C>T polymorphism and cancer risk, but the results are inconsistent. Hence, a meta-analysis was conducted to determine the association of this polymorphism with cancer risk. Materials and methods: The related articles were searched in PubMed, Embase, and Chinese National Knowledge Infrastructure databases. Pooled odds ratios and 95% confidence intervals were calculated to evaluate the strength of the associations. A random-effects model or fixed-effects model was employed depending on the heterogeneity. Results: A total of ten case-control studies involving 2,749 cancer cases and 3,398 controls were included in the meta-analysis. In overall analysis, OPN rs11730582 C>T polymorphism was not associated with cancer risk. In a stratified analysis by cancer type, no significant association was found between OPN rs11730582 C>T polymorphism and the risk of glioma, gastric cancer, and other cancers. Conclusion: This meta-analysis suggests that OPN rs11730582 C>T polymorphism is not associated with cancer susceptibility. © 2016 He and Wang. Source
