The most common metastatic site of prostate cancer is the bone, followed by the lung, bladder, liver, and adrenal gland. We report on a rare case of pancreatic metastasis from prostate cancer. A 52-year-old patient was admitted to the hospital with epigastric pain for 20 days. PET-CT showed malignant lesions in the prostate and pancreas, and prostate and pancreas puncture biopsies were performed, respectively. The patient was diagnosed as prostate cancer with pancreatic metastasis according to the pathological findings. After undergoing androgen deprivation therapy and docetaxel chemotherapy for 6 cycles, reexamination revealed that the pancreatic metastases had disappeared.

OBJECTIVETo investigate the effect of astragaloside IV (As IV) on the activation of rennin-angiotensin system in rats with pressure-overload induced cardiac hypertrophy.
METHODLeft ventricle hypertrophy was induced by abdominal aorta banding between bilateral renal aortas for 12 weeks. Rats were given astragaloside IV 1.0 mg x kg(-1) and 3.3 mg x kg(-1) for 12 weeks, respectively. After treatment, the left ventricular mass index (LVMI)was calculated by morphometry methods. Plasma and cardiac tissue angiotensin II, and plasma aldosterone were measured by ELISA method. Gene expressions of ACE, AT1 and AT2 in cardiac tissue were detected by real time PCR. Protein expressions of AT1 and AT2 in cardiac tissue were detected by Western blot.
RESULTCompared with model rats, LVMI was decreased by astragaloside IV treatment. Biochemical results indicated that the contents of angiotensin II in plasma and cardiac tissue as well as aldosterone in plasma were all increased in abdominal aorta banding rats comparing with sham-operated rats, then, decreased by astragaloside IV treatment. Gene expressions of cardiac ACE was downregulated by astragaloside IV, however, gene and protein expressions of cardiac AT2 were upregulated by astragaloside IV. Both elevated gene and protein expressions of AT1 were not attenuated by astragaloside IV.
CONCLUSIONExcessive activated rennin-angiotensin system in rats with pressure-overload induced cardiac hypertrophy is inhibited by astragaloside IV treatment.
