We propose a noniterative solution for the Perspective-n-Point ({\rm P}n{\rm P}) problem, which can robustly retrieve the optimum by solving a seventh order polynomial. The central idea consists of three steps: 1) to divide the reference points into 3-point subsets in order to achieve a series of fourth order polynomials, 2) to compute the sum of the square(More)
Therapeutic effects of presurgical long-acting octreotide treatment on tumor shrinkage, and short- and long-term postoperative GH and IGF-1 levels of acromegaly patients with invasive pituitary macroadenomas were investigated prospectively in Huashan Hospital, Shanghai, China. Thirty-nine untreated acromegaly patients, all with invasive pituitary(More)
Increasing evidence has suggested that dysregulation of certain microRNAs (miRNAs) may contribute to human disease including carcinogenesis and tumor metastasis in human. miR-124-3p is down-regulated in various cancers, and modulates proliferation and aggressiveness of cancer cells. However, the roles of miR-124-3p in human bladder cancer are elusive. Thus,(More)
OBJECTIVE This study aimed to better determine the salient signs and symptoms for diagnosis of a pituitary abscess as well as the determination of the most appropriate treatment. METHODS A retrospective analysis was performed using clinical presentations, imaging features, diagnosis and treatment of 29 patients with pituitary abscess in our hospital. (More)
OBJECTIVE Metaplastic meningioma is a rare subtype of benign meningiomas, classified as WHO grade I with well prognosis. Here we presented our experiences on 15 cases of metaplastic meningioma, to investigate the clinicopathological features, therapies and prognosis of these cases. METHODS 15 patients underwent surgical treatment for intracranial(More)
MicroRNAs (miRNAs) are small non-coding RNAs that play regulatory roles by repressing translation or cleaving RNA transcripts. Here, we report that the expression of microRNA-101 (miR-101) is down-regulated in human bladder cancer tissue versus normal adjacent tissue. To better characterize the role of miR-101 in bladder cancer, we conducted a(More)
It is increasingly clear that microRNAs play a crucial role in tumorigenesis. Recently, emerging evidence suggested that miR-26a is aberrantly expressed in tumor tissues. In our study, frequent down-regulation of miR-26a was observed in 10 human bladder cancer tissues. Forced expression of miR-26a in the bladder cancer cell line T24 inhibited cell(More)
A small population of TSCs, which form neurospheres and possess the capacity for self-renewal, has been recently identified in adult and pediatric brain tumors. They differentiate into phenotypically diverse populations, including neuronal, astrocytic, and oligodendroglial cells in vitro and recapitulate original tumors in vivo. The understanding of brain(More)
The difficulty of predicting the efficacy of somatostatin analogs (SSA) is not fully resolved. Here, we quantitatively evaluated the predictive value of relative signal intensity (rSI) on T1- and T2-weighted magnetic resonance imaging (MRI) for the short-term efficacy (3 months) of SSA therapy in patients with active acromegaly and assessed the correlation(More)
