No intraoperative fractures occurred. One stem subsided early but remained stable and osseointegrated at final follow up. There were no stem failures due to taper corrosion or modular junctional failure. Conclusions This study reports good osseointegration and low subsidence with a novel fluted, 3-degree tapered femoral stem demonstrates at medium-term follow-up in cases with severe femoral bone deficiency. 2019 Annals of Translational Medicine.

Methods This study included patients with invasive lung adenocarcinoma confirmed by pathology from July 2016 to March 2018 after surgical pulmonectomy in Thoracic Surgery Department of Beijing Chaoyang Hospital. All enrolled patients were tested for relevant gene mutations. All patients were classified as adenocarcinoma subtypes by the 2011 International Association for the Study of Lung Cancer (IASLC), American Thoracic Society (ATS) and European Respiratory Society (ERS). Patients were divided into the VTE group and the control group according to whether VTE occurred postoperatively. Baseline data, gene test results, operative data and tumor pathology data between the two groups were compared. Results According tng adenocarcinoma, acinar dominant lung adenocarcinoma, FEV1 and difference of D-dimer (d1-pre) are independent risk factors for postoperative lung cancer complicated with VTE. Conclusions The incidence of VTE was 10.2% in patients with invasive lung adenocarcinoma without prophylactic anticoagulant therapy. EGFR gene mutation is an independent risk factor for postoperative VTE in lung cancer, and the incidence of VTE in adenocarcinoma with alveolar predominance is the highest. Other independent risk factors included the difference of D-dimer (d1-pre) and preoperative FEV1. 2019 Annals of Translational Medicine.

Up to now, the mechanism behind TNBC's activity is still unclear and no candidate drug target has been identified. Thus, it is of critical importance to elucidate the pathways in TNBC and identify the relevant biomarkers. Recent studies showed that ganglioside D3 synthase (GD3s) played a very important role in development of cancers. However, the physiological functions and associated pathways of GD3s in TNBC are still unclear. Methods In silico analysis of the expression of GD3s in TNBC was conducted using The Cancer Genome Atlas (TCGA) and Oncomine databases. The proliferation of breast cancer cells was measured by MTT assay, colony formation by the soft agar method, and migration and invasion using Boyden chamber inserts. The methylation level of the gene encoding GD3s, ST8SIA1, in specimens was assessed by qMS-PCR and in silico using the UCSC gene browser. Protein expression was examined via immunohistochemistry (IHC), qRT-PCR and Western immunoblotting. Results In silico analysis showed a higher GD3s expression in ER- than ER+ breast cancers and GD3s was also highly expressed in TNBC compared to other types of breast cancers. The elevated GD3s expression in TNBC cells and tissues was associated with hypomethylation of the ST8SIA1 gene. Overexpression of GD3s in human breast cancer cells increased their proliferation, migration, invasion and colony formation ability. GD3s expression in breast cancers was closely associated with relapse-free survival (RFS) and overall survival (OS). Conclusions In summary, these results suggest that GD3s may be a potential biomarker and drug target in treatment of TNBC. 2019 Annals of Translational Medicine.

Methods Totally 824 pregnant women were enrolled and divided into a GDM group and a normal glucose tolerance (NGT) group, whose maternal fasting serum PTX3 levels, plasma glucose and insulin were collected. The beta cell function index and quantitative insulin sensitivity check index (QUICKI) was calculated and a homeostatic model assessment of insulin resistance (HOMA-IR) was used with SPSS 22 software used for statistical analysis. Results Of all subjects, 13.59% developed GDM. Compared to the NGT group, the PTX3 level was increased in the GDM group (1.48 vs. 1.52 ng/mL, P less then 0.05), and independently associated with the prediction of GDM (4.209, 95% CI, 1.756-10.091) (P=0.001). The area under receiver operating characteristic curve (AUROC) of the combined screening of PTX3 for GDM was incremented to 0.657 by the addition of maternal characteristics, and it reached a maximum of 0.743 in further combination with biochemical markers. Conclusions Serum PTX3 levels in early pregnancy may provide a useful approach for early prediction of GDM. 2019 Annals of Translational Medicine.

Association between RFC1 A80G polymorphism and NSCL/P have been studied. The published results are conflicting. Methods A meta-analysis of the association between RFC1 A80G polymorphism and NSCL/P was carried out using Stata13.0. A systematic literature search was performed through the PubMed, EMBASE, the Cochrane Library, Web of Science, ScienceDirect, EBSCOhost, China Biology Medicine databases, China National Knowledge Infrastructure and the Wanfang databases. All relevant studies up to 9 September 2019 were identified.  https://www.selleckchem.com/products/resatorvid.html  Results Nine case-control studies including 4,229 total participants (1,334 NSCL/P children, 1,515 healthy children, 656 mothers of the NSCL/P children, and 724 mothers of healthy control children) were included in this study. The meta-analysis revealed that two genetic models of RFC1 A80G polymorphism in NSCL/P children increased risk of NSCL/P the homozygote model (GG vs.
