护患交流在整体护理中的应用

不论是责任制护理还是整体护理，均以护理程序作为核心，而护患交流在护理程序中起着重要的作用。随着医学模式的转变和护理观念的更新，以病人为中心的整体护理模式正逐步地取代原有的护理模式。护患交流使护士了解病人的身心状况，促进护患间的理解与支持，提高护理质量。护患交流包括以下几方面。     

前列通瘀提取液对前列腺平滑肌细胞增殖与凋亡的作用

目的:研究前列通瘀提取液对体外培养前列腺基质平滑肌细胞增殖与凋亡的作用。方法:分别以1、2、10、50、100×10-5g/L 5种不同浓度前列通瘀提取液作用体外培养前列腺基质平滑肌细胞,采用MTT和TUNEL法分别测定抗增殖指数和凋亡指数。结果:5种不同浓度前列通瘀提取液作用48 h后抗增殖指数分别为50.61%、53.52%、56.92%、65.53%、72.94%,抗增殖效果随着浓度增大而增大。100×10-5g/L前列通瘀提取液作用24、48、72 h后凋亡指数与对照组比较差异无显著性。结论:(1~100)×10-5g/L前列通瘀提取液体外作用前列腺基质平滑肌细胞具有显著的抗增殖作用。     

New imaging techniques in prostate cancer

Correct staging of prostate cancer at initial diagnosis, as well as accurate staging and tumor localization with biochemical recurrence, remains generally inaccurate with current imaging techniques. Newer modalities are being investigated to accurately identify patients with prostate cancer at different stages of disease. Identification of locally recurrent disease or distant metastasis at the time of biochemical failure after local therapy will help guide treatment options and avoid potentially toxic salvage therapies in patients who will not benefit. A review of prostate cancer imaging literature over the past 12 months was performed to identify emerging imaging modalities that may be beneficial in the management of prostate cancer. Enhanced transrectal ultrasonography modalities, including ultrasound contrast agents, color and power Doppler, and elastrography, have demonstrated incremental benefit when combined with standard grayscale ultrasonography to accurately target and diagnose prostate cancer. Endorectal MRI, with contrast enhancement and spectroscopic imaging, shows promise in the initial staging of prostate cancer prior to local therapy. The use of positron-emission tomography scan for prostate cancer remains to be defined, but may help delineate the site of recurrence with biochemical failure after local therapy. Several new imaging modalities show promise for the evaluation of the patient with prostate cancer. Enhanced ultrasonography techniques may prove to be more accurate in diagnosing prostate cancer over standard gray-scale ultrasonography. Accumulating evidence supports the use of endorectal MRI and spectroscopy to help treatment planning with either surgical or radiotherapeutic approaches. Although intriguing, the available data for positron-emission tomography in prostate cancer remains too shallow to advocate routine use.     

Management of the complications of external beam radiotherapy and brachytherapy

External beam radiation therapy (EBRT) and brachytherapy are common treatment modalities for newly diagnosed prostate cancer. What complications can patients and physicians expect following these therapies? How are these conditions diagnosed and treated? In this article, we examine several of the most common acute and delayed complications of radiation therapy for prostate cancer. In addition, we discuss appropriate follow-up diagnostics for these patients and our suggestions for management of the main complications that may develop.     

Chronic prostatitis/chronic pelvic pain syndrome and interstitial cystitis: Are they related?

Interstitial cystitis and chronic prostatitis/chronic pelvic pain syndrome are clinical syndromes characterized by pelvic pain with or without voiding symptoms such as urgency and frequency. There are many similarities in their epidemiology, adverse effect on quality of life, etiology/pathophysiology, natural history, and response to similar treatments. However, overlapping clinical definitions and similar entrance criteria for large-scale cohort studies make comparisons problematic. Newer efforts to classify pelvic pain syndromes should help in our recognition that interstitial cystitis and chronic prostatitis/chronic pelvic pain syndrome likely are not organ-specific syndromes but urogenital manifestations of regional or systemic abnormalities.
