目的 探讨全人/整体护理对晚期癌症患者生活质量的影响。 方法 将2007年11月－2008年7月60例确诊为晚期癌症的患者随机分为试验组和对照组，均规范接受阿片类药物镇痛和针对其他痛苦症状的药物控制治疗。在此基础上，试验组再增加躯体照护、心理疏导、灵性关怀等全人/整体护理，并就两组在疼痛缓解、活动能力和生活质量改善等方面的效果进行比较。 结果 观察期内，试验组在疼痛缓解、活动能力及生活质量改善方面明显优于对照组，两组比较差异均有统计学意义（P＜0.05）。 结论 在药物治疗基础上，运用全人/整体护理能够明显提高晚期癌症患者及其家属的生活质量。
In order to solve imperfection of heart rate extraction by method of traditional ballistocardiogram (BCG), this paper proposes an improved method for detecting heart rate by BCG. First, weak cardiac activity signals are acquired in real time by embedded sensors. Local BCG beats are obtained by signal filtering and signal conversion. Second, the heart rate is estimated directly from the BCG beat without the use of a heartbeat template. Compared with other methods, the proposed method has strong advantages in heart rate data accuracy and anti-interference, and it also realizes non-contact online detection. Finally, by analyzing the data of more than 20,000 heart rates of 13 subjects, the average beat error was 0.86% and the coverage was 96.71%. It provides a new way to estimate heart rate for hospital clinical and home care.
ObjectiveTo compare the clinicopathological characteristics and prognosis of young early breast cancer patients with different human epidermal growth factor receptor 2 (HER2) expression levels, and to analyze the clinicopathological characteristics and prognosis of young early breast cancer patients with low HER2 expression. MethodsA total of 1 723 breast cancer patients who were treated in the Department of Breast Surgery of the First Affiliated Hospital of Xi’an Jiaotong University between June 2016 and June 2018 were collected and divided into three groups: HER2-negative, low-expression, and high-expression. The clinicopathological characteristics of the three groups were compared, and the relationship between HER2 expression and patients’ prognosis was analyzed. ResultsThere were 512 HER2-negative patients, 748 HER2-low expression patients, and 463 HER2-high expression patients. The results of the clinical pathological characteristics analysis of the three groups of patients showed that there were no statistical differences in marital status, menopausal status, family history, single T stage (tumor size), single M stage (distant metastasis), affected side, vascular tumor thrombus, and radiotherapy in the three groups of breast cancer patients with different HER2 expression levels (P>0.05). However, there were statistical differences in age, Ki-67 expression level, N stage, TNM stage, surgical method, estrogen receptor and progesterone receptor status, histological type, histological grade, whether to receive neoadjuvant therapy and adjuvant chemotherapy in breast cancer patients with different HER2 expression levels (P<0.05). The results of survival analysis showed that the prognosis of early breast cancer patients may not be significantly correlated with the HER2 expression level, and the prognosis of young early breast cancer patients may also not be statistically correlated with the HER2 expression status. ConclusionsBreast cancer patients with different HER2 expression levels differ in multiple clinicopathological characteristics, but these differences do not significantly affect the prognosis of the patients. Especially for early-stage breast cancer, HER2 expression levels do not seem to have a significant impact on prognosis. This suggests that HER2 status may not be a decisive factor in treatment and prognosis assessment, and other pathological characteristics and treatment methods need to be considered comprehensively. The prognosis of young breast cancer patients in early stage may also not be statistically correlated with HER2 expression status.
Objective To evaluate the effectiveness of terazosin, tamsulosin and finasteride for benign prostatic hyperplasia (BPH). Methods We searched the related original studies all over the world, and only included randomized controlled trials (RCT) and quasi-randomized controlled trials (CCT). MEDLINE (1966 to Dec. 2004), EMBASE (1984 to Dec. 2004), The Cochrane Library (Issue 4, 2004) and four Chinese databases were electronically searched and 10 related journals were handsearched. The studies included in the references of eligible studies were additionally searched. Two reviewers independently screened the studies for eligibility, evaluated the quality and extracted the data from the eligible studies, with confirmation by cross-checking. Divergences of opinion were consulted by a third party. Meta-analysis was performed by using RevMan 4.2 software. Results Twelve original studies involving 2 471 participants met inclusion criteria. Compared with terazosin, tamsulosin could improve international prostatic symptom score, with WMD 0.75, 95% confidence interval (CI) 0.03 to 1.46, P=0.04. There was no statistical difference between terazosin and tamsulosin in improving the average rate of urine flow (WMD 0.23, 95%CI -0.39 to 0.85, P=0.46), the residual urine volume (WMD 0.82, 95%CI -2.92 to 4.57, P=0.67) and in diminishing the volume of prostate (WMD 2.20, 95%CI -3.99 to 8.39, P=0.49). There was no statistical difference between finasteride and tamsulosin in improving the international prostatic symptom score (WMD 0.65, 95%CI -0.45 to 1.75, P=0.25) or the max rate of urine flow (WMD 0.39, 95%CI -0.72 to 1.51, P=0.49). Only two studies compared finasteride with terazosin and had different conclusions. Only one study compared finasteride or terazosin with a combination of these drugs suggested that the combination had higher effective power than finasteride alone but no difference with terazosin alone. Conclusions Although the effectiveness in some aspects is higher in the tamsulosin group, there is not enough evidence to show which one is the best among these three drugs. The combination of finasteride and terazosin does not show more effectiveness than terazosin alone. This review suggests that tamsulosin alone should be used for the treatment of BPH and the combination needs to be identified by better evidence. It is important to improve the quality of original studies.
