Proximal femoral nail antirotation versus hemiarthroplasty: A study for the treatment of intertrochanteric fractures

Abstract: Intertrochanteric fractures in elderly patients are always associated with poor prognosis in the functional outcome as a result of the complications and mortality. A retrospective study was performed in our institution, 303 consecutive patients were followed up with mean age of 81.7 years. 147 were treated with PFNA, and 156 were underwent hemiarthroplasty. The average follow-up period was 39.9 months. The mortality at 1 month, 1 year, 3 years and the total was 6.6%, 18.6%, 27.6% and 30.3%, respectively. There were no significant differences between the groups in terms of demographic data. There were statistical significances in the operative statistics, especially the anaesthesia, operation lasting time, blood loss, blood transfusion and the drainage. There was no significant difference in Harris Hip Score between PFNA and hemiarthroplasty group, but the detail items were quite different. Significant difference was found in the excellent-to-fine rate (PFNA 90.2% and hemiarthroplasty 79.6%). Complications occurred in 34 patients, although incidences of complications were higher in hemiarthroplasty group (14.1% vs. PFNA 8.96%), no statistical difference was found. For elderly patients with intertrochanteric fractures, PFNA was superior to hemiarthroplasty according to the operative statistics, but there were no significant differences in functional outcome.

Efficacy and safety of adalimumab in Chinese adults with active ankylosing spondylitis: results of a randomised, controlled trial

Abstract: Background and objectives Efficacy of adalimumab for ankylosing spondylitis (AS) has been established for Western populations but not in the Chinese population. This study is the first to evaluate the efficacy and safety of adalimumab in Chinese patients with AS. Methods Chinese adults with active AS who had an inadequate response or were intolerant to ≥1 non-steroidal anti-inflammatory drugs were randomised to adalimumab 40 mg (N=229) or matching placebo (N=115) subcutaneously every other week (EOW) for 12 weeks, followed by a 12-week open-label adalimumab 40 mg EOW phase. The primary efficacy endpoint was the percentage of patients meeting the Assessment in Spondyloarthritis International Society (ASAS20) response criteria at week 12. The recently developed AS Disease Activity Score (ASDAS), as well as efficacy measures of spinal mobility, disease activity, physical function and quality of life were evaluated. Results At week 12, adalimumab treatment resulted in a significantly greater percentage of ASAS20 responders than placebo (67.2% versus 30.4%, respectively; p Conclusions Adalimumab significantly reduced the signs and symptoms, improved physical function and quality of life of Chinese patients with active AS, and was generally safe and well tolerated in this population.

Phospholipids-based microbubbles sonoporation pore size and reseal of cell membrane cultured in vitro.

Abstract: Objective: To investigate phospholipids-based microbubbles induced sonoporation and cell membrane reseal in vitro under various conditions.Methods: A breast cancer cell line SK-BR-3 was used to investigate ultrasonic sonoporation under various conditions. Atomic force microscopy (AFM) scanning techniques were employed to observe the change of membrane pores.Results: Normal SK-BR-3 cells membrane pores were evenly distributed and less than 1 μm. After ultrasound exposure, membrane pores were enlarged at different degree depending on ultrasound exposure durations, filling gas species and microbubble suspension concentration. With microbubble suspension concentration being increased to 5% or ultrasound exposure reached 30 s, membrane pores in fluorocarbon (C3F8 or SF6)-filled microbubble groups exceeded 1 μm, which were significantly larger than that of air-filled microbubble group. Membrane pores were about 2–3 μm under ultrasound 60 s with 5% fluorocarbon-filled microbubble suspension. After 24 h of incuba...

CT characteristics and pathological implications of early stage (T1N0M0) lung adenocarcinoma with pure ground-glass opacity

Abstract: To analyze the CT characteristics and pathological classification of early lung adenocarcinoma (T1N0M0) with pure ground-glass opacity (pGGO). Ninety-four lesions with pGGO on CT in 88 patients with T1N0M0 lung adenocarcinoma were selected from January 2010 to December 2012. All lesions were confirmed by pathology. CT appearances were analyzed including lesion location, size, density, uniformity, shape, margin, tumour-lung interface, internal and surrounding malignant signs. Lesion size and density were compared using analysis of variance, lesion size also assessed using ROC curves. Gender of patients, lesion location and CT appearances were compared using χ2-test. There were no significant differences in gender, lesion location and density with histological invasiveness (P > 0.05). The ROC curve showed that the possibility of invasive lesion was 88.73 % when diameter of lesion was more than 10.5 mm. There was a significant difference between lesion uniformity and histological invasiveness (P = 0.01). There were significant differences in margin, tumour-lung interface, air bronchogram with histological invasiveness ( P = 0.02,P = 0.00,P = 0.048). The correlation index of lesion size and uniformity was r = 0.45 (P = 0.00). The lesion size and uniformity, tumour-lung interface and the air bronchogram can help predict invasive extent of early stage lung adenocarcinoma with pGGO. • CT characteristics and pathological classification of pGGO lung adenocarcinoma smaller than 3 cm • The optimal cut-off value for discriminating preinvasive from invasive lesions was 10.5 mm • Uniformity was significant difference between histological subtypes and correlated with lesion size • Tumour margin, tumour-lung interface and air bronchogram showed different between histological types • No significant difference in gender, lesion location and density with histological subtypes

Understanding the gut-kidney axis among biopsy-proven diabetic nephropathy, type 2 diabetes mellitus and healthy controls: an analysis of the gut microbiota composition.

Abstract: Type 2 diabetes mellitus (T2DM) has a rising prevalence and gut microbiota involvement is increasingly recognized. Diabetic nephropathy (DN) is a major complication of T2DM. The aim of the study was to understand the gut–kidney axis by an analysis of gut microbiota composition among biopsy-proven DN, T2DM without kidney disease, and healthy control. Fecal samples were collected from 14 DNs, 14 age/gender-matched T2DMs without renal diseases (DM), 14 age and gender-matched healthy controls (HC) and household contacts (HH) of DM group. The microbiota composition was analyzed by 16sRNA microbial profiling approach. Substantial differences were found in the richness of gut microbiota and the variation of bacteria population in DM compared to HC, and DN compared to DM, respectively. DM could be accurately distinguished from age/gender-matched healthy controls by the variable of genus g_Prevotella_9 (AUC = 0.9), and DN patients could be accurately distinguished from age/gender-matched DM by the variables of two genera (g_Escherichia-Shigella and g_Prevotella_9, AUC = 0.86). The microbiota composition of HH group was close to that of HC group, and was different from DM group. Under the same diet, DM could be more accurately detected by the same genus (g_Prevotella_9, AUC = 0.92). Gut microbiota composition was explored to be related to the occurrence of biopsy-proven DN from DM. DM could be distinguished from HC by detecting g_Prevotella_9 level in feces, while DN was different from DM by the variables of g_Escherichia-Shigella and g_Prevotella_9, which potentially contributed to the physiopathological diagnosis of DN from DM.
