Evaluation of Closed System Transfer Devices in Preventing Chemotherapy Agents Contamination During Compounding Process-A Single and Comparative Study in China.

Aim: We performed a comparative study to investigate the efficacy of closed system transfer devices (CSTDs) on the safe handling of injectable hazardous drugs (HDs).

Methods: The exposure assessments of cyclophosphamide and cytarabine were performed under traditional or CSTDs. For preparation activity, chemotherapy contamination samples on protective equipment (such as gloves and masks) were collected.

[Expressions of transient receptor potential A1 and related inflammatory factors in the rat model of prostatic inflammation].

Objective: To explore the molecular mechanism of pain associated with chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) in the rat model of prostatic inflammation.

Methods: Thirty-six male SD rats were equally randomized to an experimental and a control group, the former injected with 50 μl of 3% λ-carrageenan into the ventral prostate to make the model of non-bacterial prostatic inflammation, while the latter with the same volume of sterile saline solution. At 1, 2 and 4 weeks after modeling, the prostate, L6-S1 dorsal root ganglion (DRG) and spinal cord were harvested for examination of the expressions of the nerve growth factor (NGF), transient receptor potential ankyrin 1 (TRPA1), and calcitonin-gene-related peptide (CGRP) by immunohistochemistry and Western blot.

Pathologic analysis, diagnosis and treatment of adrenal myelolipoma.

With the widespread use of non-invasive imaging modalities, the incidental detection of myelolipoma has become more common. We analyze the clinical data of 4 typical cases of unilateral adrenal myelolipomas, including 1 hormonally inactive patient and 3 hormonally active cases with hyperaldosteronemia, hypercortisolism and hyperandrogenemia. Obvious differences were found in the pathological sections.

[Hormonal therapy for prostate cancer: methods and prognosis].

Objective: To search for an effective hormonal therapy for delaying the progression of prostate cancer to androgen-independent prostate cancer (AIPC).

Methods: This study included 93 cases of prostate cancer confirmed by transrectal ultrasound-guided biopsy, 22 treated by bilateral orchiectomy plus bicalutamide as a continuous androgen deprivation (CAD) therapy, and the other 71 by the intermittent androgen deprivation (IAD) therapy, the latter divided into a standard IAD group (n = 29) and a modified IAD group (n = 42) to be treated by maximum androgen blockage (MAB) until the serum PSA level decreased to less than 0.2 microg/L and the medication was maintained for 3 months.

Classification, diagnosis and treatment of ACTH-independent macronodular adrenal hyperplasia.

ACTH-independent macronodular adrenal hyperplasia (AIMAH) is a distinctive subtype of Cushing's syndrome (CS), with different clinical manifestations according to the level of serum cortisol. Based on clinical manifestations and serum cortisol, we divide AIMAH into three types, subclinical AIMAH, clinical AIMAH and high-risk AIMAH, with varied treatment methods being adapted to different subtypes. At the same time, we describe 3 patients who represent these subtypes of this disease, and review some cases of AIMAH which have been previously reported in the English literature.

[PSA-based screening for prostate cancer: a comparative analysis].

PSA-based screening has always been one of the controversial topics among urological researchers. In spite of its benefit in detecting early prostate cancer, PSA-based screening may not only result in widespread overdiagnosis and overtreatment of an often indolent disease, which is life-threatening in only a minority of patients, but also subject participators to such complications as erectile dysfunction and incontinence. Besides, whether PSA-based screening can reduce prostate cancer specific mortality has received considerable attention.
