Child inflammatory myofibroblastic tumor of the kidney misdiagnosed as Wilms' tumor: case report.

Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor with recurrent potential, most commonly occurring in the lung but rarely in the kidney with nonspecific clinical symptoms and radiographic features, thus may be misdiagnosed as primary malignant lesions. We described a 6-year-old boy with renal IMT misdiagnosed as Wilms' tumor and then treated with right nephrectomy. It should be emphasized that in addition to the most common renal tumors in children, IMT should also be taken as a differential diagnosis.

Asymptomatic adult Wilms' tumor: A case report.

Wilms' tumor, also called nephroblastoma, is an extremely uncommon kidney tumor of adulthood. We reported a adult man with a left kidney mass diagnosed as Wilms' tumor. Case presentation: A 25-year-old man was hospitalized due to injury of the anterior cruciate ligament of the right knee.

Computed Tomography and Magnetic Resonance Imaging Appearances of Abdomen and Pelvis Gossypibomas at the Varied Durations After Cesarean Section.

The incidence of gossypiboma is considerably higher in open cavity surgeries, among which cesarean section ranks number one. However, it is difficult to diagnose abdomen or pelvic gossypibomas after cesarean section. We retrospectively analyzed the clinical and imaging data of three pathologically confirmed gossypiboma patients at varied durations after cesarean section.

Cytosine 5-hydroxymethylation regulates VHL gene expression in renal clear cell carcinoma.

Cytosine5-hyxymethylation (5hmC)which is a new epigenetic modification form plays important roles in the development and progression of tumors. In the present study, we observed that levels of 5hmC in the promoter region of Von Hippel-Lindau (VHL) were lower in 97 samples of renal clear cell carcinoma tissue than in matched adjacent benign tissues. Moreover, when the cancer tissue samples were divided based on pathological staging, VHL expression and the level of 5hmC in the VHL promoter were both lower in pathological grade III tumors than in grades I or II.

TGF-beta1 reverses inhibition of COX-2 with NS398 and increases invasion in prostate cancer cells.

Bone-derived transforming growth factor (TGF)-beta1 leads to tumor growth, osteoblastic lesions and more invasion. Degradation of basement membranes caused by cyclooxygenase (COX)-2 is known as a distinctive feature of invasive cells. We investigated inhibition of COX-2 with NS398 in PC-3 and LNCaP cell lines.

[Cigarette smoking affects cyclogeny of spermatogenic cells in rats].

Objective: To determine the effects of cigarette smoking on the cyclogeny of spermatogenic cells in rats.

Methods: Rat models of passive smoking were established using a self-made smoking device, and then allocated randomly into two passive smoking groups (A and B, n = 10) and two corresponding control groups (C and D, n = 10). Groups A and B were exposed to cigarette smoke for 8 weeks, followed by the sacrifice of the rats in Groups A and C.

Expressions of voltage-gated K+ channel 2.1 and 2.2 in rat bladder with detrusor hyperreflexia.

Background: Voltage-gated K+ channel (Kv) plays a critical role in the modulation of detrusor contraction. This study was conducted to investigate the expressions of Kv2.1 and Kv2.
