Long-term prognosis and quality of life in patients with early rheumatoid arthritis treated according to the 2015 ACR guideline (LELAND): protocol for a multicentre prospective observational study in Southern China.

Introduction: Rheumatoid arthritis (RA) is a chronic systemic disease and one of the most disabling diseases for patients. The American College of Rheumatology (ACR) issued a new guideline in 2015 for the treatment of RA based on the treat-to-target strategy to achieve better outcomes. This study will focus on the real-world rates of remission and low disease activity of patients with early RA in China, who will be treated according to the 2015 ACR guideline.

MicroRNA‑198 contributes to lupus nephritis progression by inhibition of phosphatase and tensin homology deleted on chromosome ten expression.

A number of short noncoding microRNAs (miRs) have been demonstrated to be highly expressed in many kidney diseases such as renal cancer and lupus nephritis (LN); however, these results have not been extensively investigated. The aim of the present study was to investigate the expression and function of miR‑198 in LN based on the previous studies. miR‑198 expression level in systemic lupus erythematosus (SLE) patients was determined to determine its clinicopathological significance and effect on glomerular cell proliferation.

[Fast edge extraction for ultrasound image of breast tumor based on fuzzy number].

An accurate edge extraction method for the ultrasound breast tumor image is useful for classifying tumors as benign or malignant. This paper refers to a fast technique to extract edge of breast tumor from ultrasound image. This method uses the triangular fuzzy number to build up a fuzzy number plane whose basic unit is the marching square.

Staurosporine-induced G2/M arrest in primary effusion lymphoma BCBL-1 cells.

Staurosporine, an inhibitor of protein kinase C, is a potential antitumor drug and its derivatives are used as anticancer drugs in clinical trials. Human herpesvirus 8 (HHV-8) is implicated in all forms of Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman's disease (MCD), indicating it to be a DNA tumor virus. It is difficult to culture cell lines derived from KS patients; we therefore used a cell line derived from PEL (BCBL-1) to investigate whether staurosporine affects the HHV-8-related tumors.
