Silencing of SIAH1 in SH-SY5Y affects α-synuclein degradation pathway.
Seven in absentia homolog (SIAH) is a ubiquitin ligase that monoubiquitinates α-synuclein. Lewy bodies are characteristically rich in monoubiquitinated α-synuclein. We aimed to determine the effect of siRNA-SIAH1 on α-synuclein autophagy and UPS degradation in SH-SY5Y. ⋯ These data show silencing SIAH1 increased cell proliferation and inhibited apoptosis in SH-SY5Y neuroblastoma cells. SIAH1 knockdown enhanced the clearance of non-aggregated α-synuclein by UPS. SIAH1 is a potential target for treatment of Parkinson's disease.

Review Meta AnalysisEpsilon aminocaproic acid reduces blood transfusion and improves the coagulation test after pediatric open-heart surgery: a meta-analysis of 5 clinical trials.
Excessive postoperative blood loss after cardiopulmonary bypass is a common problem, especially in patients suffering from congenital heart diseases. The efficacy of epsilon aminocaproic acid (EACA) as a prophylactic treatment for postoperative bleeding after pediatric open-heart surgery has not been determined. This meta-analysis investigates the efficacy of EACA in the minimization of bleeding and blood transfusion and the maintenance of coagulation tests after pediatric open-heart surgery. ⋯ Prophylactic EACA minimizes postoperative blood transfusion and helps maintain coagulation in pediatric patients undergoing open-heart surgery. Therefore, the results of this study indicate that adjunctive EACA is a good choice for the prevention of postoperative blood transfusion following pediatric cardiac surgery.

Genetic polymorphisms of the TNF-α-308G/A are associated with metabolic syndrome in asthmatic patients from Hebei province, China.
Asthma is a complex inflammatory disease involving the critical actions of several important cytokines. Epidemiological data show that obesity could increase the risk of asthma, and insulin resistance, or metabolic syndrome are an important risk factor for obesity asthma. Some studies identified that upstream of the transcription start site within the TNF-α gene promoter region-308 polymorphism was associated insulin resistance or metabolic disorders, while this site was closely related to asthma. ⋯ After analyzing the relationship between biochemical features of patients and genotype of TNF-α-308G/A, we found levels of LDL cholesterol, TNF-α and insulin, and HOMA-IR were significantly higher in the asthmatic patients carrying the GA and AA genotypes than in the carriers of GG genotype of rs1800629 (P = 0.029, P = 0.022, P = 0.043, respectively). Thus, our data suggested that TNF-α-308G/A variation was related to metabolic phenotype in asthma patients. Furthermore, we first identified TNF-α-308 A allele was the risk factor for asthmatic patients with Mets in Hebei population, China.

Expression and mechanism of action of the SARI tumor suppressor in prostate cancer.
The objective of this study was to assess the expression of SARI (Suppressor of AP-1, Regulated by IFN) in prostate cancer (Pca) and explore the effects and possible mechanism of action of SARI in the occurrence and development of Pca. In the current study, the expression of SARI was detected using PCR in 40 patients with prostate cancer, 20 patients with prostatic hyperplasia, and prostate cancer cells (LNCaP. and DU145). In addition, the effects of the pro-inflammatory cytokine interferon (IFN)-β on the expression of SARI in DU145 prostate cancer cells and the possible potential signaling pathways activated by SARI were detected using RT-PCR. ⋯ Finally, MTT assays demonstrated that DU145 cells growth slowed down, flow cytometry demonstrated that IFN-β induced apoptosis increased from 0.0343 ± 0.0039 to 0.0612 + 0.0025 in DU145 prostate cancer cells. In conclusion, the results of the current study suggest that SARI might play an important role in the occurrence and development of prostate cancer. In addition, IFN-β might inhibit the growth of prostate cancer and promote cellular apoptosis by inducing the expression of SARI.

Case ReportsMultfocal micronodular pneumocyte hyperplasia in a Chinese man masquerading as miliary tuberculosis.
Multifocal Micronodular Pneumocyte Hyperplasia (MMPH) is a rare and histologically, distinctive pulmonary manifestation of tuberous sclerosis complex (TSC) characterized by numerous and extensive proliferative lesions of type II pneumocytes similar to atypical adenomatous hyperplasia (AAH) or non-mucinous adenocarcinoma in situ (AIS). We reported MMPH in a 38-year-old Chinese man with TSC masquerading for 16 months as miliary tuberculosis and discussed the differential diagnosis.
