[Relationship between programmed cell death 5 protein expression and prognosis of renal clear cell carcinoma].

Objective: To study the role of programmed cell death 5 (PDCD5) protein in the oncogenesis and development of renal clear cell carcinoma and its association with the prognosis of the malignancy.

Methods: PDCD5 expression was assayed immunohistochemically in 46 cases of human renal clear cell carcinoma, and the patients' survival was followed up.

Results: PDCD5 staining in the adjacent normal tissue of the tumor was significantly stronger than that in the tumor tissue, and PDCD5 expression was significantly correlated with the tumor grade, stage and prognosis.

[Expression of TFAR19(PDCD5) in normal human kidney, renal clear cell carcinoma, normal human bladder and bladder carcinoma].

Objective: To detect the expression of apoptosis gene PDCD5 in tissues of normal human kidney, renal clear cell carcinoma, normal bladder and bladder carcinoma, and explore the role of PDCD5 gene in renal clear cell carcinoma and bladder carcinoma.

Methods: Indirect immunohistochemistry was employed to detect PDCD5 expression in 63 kidney specimens and 42 bladder specimens. Positive expression rates and intensity of PDCD5 protein expression in the kidney tissue were investigated microscopically and by computerized image analysis.

[Isolation of Malassezia furfur from the groin abscess of a renal transplant patient].

We report here the discovery of Malassezia furfur from a groin abscess of a renal transplant patient. A 33-year-old male patient was admitted to our hospital because of a high fever and a persistent inflammatory nodule on his right groin for one week. He had received a renal transplant 3 years before and remained on immunosuppressive agents.

[Application of methylene blue staining in detection of Malassezia].

Objective: To assess the value of methylene blue and parker ink staining in the detection of Malassezia.

Methods: Detecting Malassezia in three dermatoses samples (pityriasis versicolor, Malassezia folliculitis and dandruff) stained by methylene blue (3 g/L) or parker ink. Comparing the effectiveness and the positive rates of Malassezia detection between the two staining methods.

Frequency and CT patterns of bowel wall thickening proximal to cancer of the colon.

Objective: This study was performed to determine the frequency and patterns of colon wall thickening seen on CT of patients with adenocarcinoma of the colon.

Materials And Methods: Preoperative abdominal and pelvic CT scans of 185 patients with surgically proven adenocarcinoma of the colon were retrospectively evaluated by three abdominal radiologists for the presence of colon obstruction and colon wall thickening proximal to the colon adenocarcinoma. The distributions and patterns of colon wall thickening were categorized by consensus.
