Prostate cancer treated with reduced-volume intensity-modulated radiation therapy: Report on the 5-year outcome of a prospective series.

How to define a clinical target volume (CTV) as small as possible for prostate cancer to reduce the dose received by normal organs is an interesting study. We conduct a research to analyze the clinical efficacy of intensity modulated radiotherapy (IMRT) using reduced CTV in the treatment of prostate cancer. From January 2006 to June 2010, 78 patients with prostate cancer were treated with IMRT according to this institutional protocol.

Effect of CYP3A4 and CYP3A5 Genetic Polymorphisms on the Pharmacokinetics of Sirolimus in Healthy Chinese Volunteers.

Background: Sirolimus is a promising immunosuppressive drug for preventing the rejection of organ transplants. However, inter-individual variability in sirolimus pharmacokinetics causes adverse drug reactions, compromising therapeutic efficacy. Sirolimus is primarily metabolized by cytochrome CYP3A4 and CYP3A5.

Preparation and Characterization of Silymarin Synchronized and Sustained Release Dropping Pill.

Purpose: This study aimed to develop a synchronized and sustained-release silymarin dropping pill, and to evaluate its pharmacokinetic characteristics.

Method: Polyoxyethylene stearate, glyceryl monostearate, and stearic acid were used to prepare the dropping pills. X-ray powder diffraction, differential scanning calorimetry, and release were used to evaluate its physicochemical properties.

Long-term cancer-related fatigue outcomes in patients with locally advanced prostate cancer after intensity-modulated radiotherapy combined with hormonal therapy.

The aim of our study was to investigate the relationship between cancer-related fatigue and clinical parameters, and the effect factors of fatigue for the prostate cancer patients. Long-term follow-up is performed using the Fatigue Symptom Inventory before treatment (A), at the end of intensity-modulated radiotherapy (B), and 3 months (C), 12 months (D), 24 months (E), 36 months (F), and 48 months (G) after the end of intensity-modulated radiotherapy. Three dimensions of fatigue are assessed during follow-up: severity, perceived interference with quality of life, and duration in the past week.

Olive oil exhibits osteoprotection in ovariectomized rats without estrogenic effects.

The present study was designed to evaluate the effect of olive oil on bone and uterus in ovariectomized rats. A total of 34 surgically ovariectomized or sham-operated virgin Sprague-Dawley rats were divided into four groups: i) Sham-operated control rats (sham group); ii) Ovariectomized rats (OVX group); iii) Olive oil-supplemented ovariectomized rats (olive group); and iv) Diethylstilbestrol-supplemented ovariectomized rats (E group). At 12 weeks following left ventricular blood sacrificed to detect plasma estradiol (E), interleukin-1β (IL-1β) and IL-6 levels.

Preparation and characterization of silymarin synchronized-release microporous osmotic pump tablets.

The pharmacological activity of herbal medicine is an overall action of each component in accordance with their original proportion. An efficient, sustained, and controlled-release drug delivery system of herbal medicine should ensure the synchronized drug release of each active component during the entire release procedure. In this study, silymarin (SM), a poorly soluble herbal medicine, was selected as a model drug to develop a synchronized-release drug delivery system: an SM microporous osmotic pump (MPOP) tablet.

Relationships of related genetic polymorphisms and individualized medication of tacrolimus in patients with renal transplantation.

The aim of this study was to establish clinical and genetic factors-based individual administration model of tacrolimus for Chinese Han patients after renal transplantation (RT). The genetic polymorphisms of CYP3A4, CYP3A5 and MDR1 in 216 RT patients were detected by PCR-RFLP, the genetic and clinical factors and blood concentration/dose × body weight (C/D) values of tacrolimus were performed the single factor correlation analysis, and established the dose prediction algorithm of tacrolimus by stepwise multiple regression analysis. CYP3A5*3, hematocrit and albumin were correlated with the C/D values of tacrolimus, the best regression model could explain 28.

A missense mutation in TMEM67 causes Meckel-Gruber syndrome type 3 (MKS3): a family from China.

Meckel-Gruber syndrome (MKS) is a lethal autosomal recessive condition characterized by renal cysts and variably associated features, including developmental anomalies of the central nervous system (typically encephalocele), hepatic ductal dysplasia and cysts, and polydactyly. Genetic heterogeneity has been demonstrated at eleven loci, MKS1-11. Here, we present the clinical and molecular characteristics of a Chinese MKS3 family with occipital encephalocele and kidney enlargement.

CYP3A4∗18B and CYP3A5∗3 polymorphisms contribute to pharmacokinetic variability of cyclosporine among healthy Chinese subjects.

Aim: Cyclosporine is an immunosuppressant drug used to prevent allograft rejection. It is metabolized by CYP3A4 and CYP3A5, has a narrow therapeutic index, and variable pharmacokinetics. Here, we investigated whether CYP3A5∗3 and CYP3A4∗18B polymorphisms contribute to inter-individual pharmacokinetic variability in healthy subjects.

Single-stage posterior vertebral column resection and internal fixation for old fracture-dislocations of thoracolumbar spine: a case series and systematic review.

Purpose: To evaluate the efficacy of single-stage posterior vertebral column resection for old thoracolumbar fracture-dislocations with spinal cord injury.

Methods: From January 2007 to June 2013, twelve male patients (average age, 32.6 years; range 19-57 years) with old fracture-dislocations of the thoracolumbar spine and spinal cord injury underwent single-stage posterior vertebral column resection and internal fixation.

Long-term quality of life outcomes in patients with locally advanced prostate cancer after intensity-modulated radiotherapy combined with androgen deprivation.

With great improvements in survival in patients with locally advanced prostate cancer, quality of life (QOL) is becoming an important factor in the selection of treatment. The aim of this study was to evaluate changes in health-related QOL in patients with locally advanced prostate cancer after intensity-modulated radiotherapy (IMRT) combined with androgen deprivation therapy. Patients were treated with IMRT combined with androgen deprivation.
