Objective: To evaluate the efficacy and safety of essential oil treatment for type Ⅲ chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS). Methods: A randomized controlled trial was conducted from December 2014 to October 2015. Seventy type Ⅲ CP/CPPS patients were assigned to the essential oil group(35 cases) or almond placebo oil control group(35 cases) by a random number table. The oil was smeared by self-massage on the suprapubic and sacral region once a day for 4 weeks. The National Institutes of Health Chronic Prostatitis Syndrome Index(NIH-CPSI) and expressed prostatic secretions(EPS) were examined. The primary outcome was NIH-CPSI pain domain. The secondary outcomes included other NIH-CPSI domains and laboratory examinations of EPS. Adverse events were also observed. Results: Sixty-six subjects completed the full 4-week treatment. There was no significant difference between almond oil control and essential oil groups in terms of the total score of NIH-CPSI, pain, quality of life and urination domain scores of NIH-CPSI and EPS examinations(P0.05). In the essential oil group, pain between rectum and testicles(perineum) in the domain of pain or discomfort was significantly reduced at week 2 and week 4 compared with almond oil control group(P0.01). No serious adverse events occurred. Conclusion: The essential oil may reduce the pain or discomfort in the perineum region in patients with CP/CPPS. 相似文献

BACKGROUNDThe cardiovascular hazards of total homocysteine (tHcy) are long known. In addition, despite the acknowledgment on the importance of low ankle-brachial index (ABI) (< 0.9), borderline ABI (0.91-0.99) was once commonly overlooked. This study aims to explore the independent and joint effect of tHcy level and borderline ABI on all-cause death in hypertensive population.METHODSThis study included 10,538 participants from China H-type Hypertension Registry Study. ABI was described into two groups: normal ABI (1.00-1.40) and borderline ABI. tHcy level was also divided into two groups: < 15.02 and ≥ 15.02 μmo/L. Four groups were analyzed, using COX proportional hazard regression model, separately and pairwise to observe the independent and joint effect on all-cause death.RESULTSA total of 126 (1.2%) deaths were observed in the 1.7 years follow-up time. Borderline ABI has a higher predicted risk of death than normal ABI (HR = 1.87, 95%CI: 1.17-3.00) after adjusting for potential covariates. Compare with tHcy level < 15.02 μmo/L (low tHcy), those with tHcy ≥ 15.02 μmo/L (high tHcy) had higher risk to event outcome (HR = 1.99, 95% CI: 1.30-3.05). According to the cumulative hazard curve, group with borderline ABI and high tHcy level has significantly higher altitude and larger increasing rate over follow-up period compare to other groups. Among those with borderline ABI, participants with high tHcy had higher death risk than those with low tHcy, nevertheless, no significant different between borderline and normal ABI among those with low tHcy levels.CONCLUSIONSBorderline ABI and tHcy level both have independent predictive value on all-cause death. The combined group of borderline ABI and high tHcy has highest risk factor of outcomes, which suggested the mutual additive value of borderline ABI and tHcy. More attention should be given to the importance of borderline ABI in hypertensive population, especially with elevated tHcy level.Homocysteine (Hcy) is a sulfur-containing, non-proteinogenic amino acid synthesized through the transmethylation of amino acid methionine from one-carbon metabolism. Elevated plasma total homocysteine (tHcy) level is associated with endothelial dysfunction, increased blood coagulation, and metabolic disturbance, promoting cardiovascular diseases, stroke, and coronary artery disease.[1,2] Notably, patients with high Hcy levels and concomitant hypertension were suggested to be at particularly higher risk.[3] Moreover, increasing studies have explored a positive association between advanced Hcy level with all-cause mortality. According to a recent dose-response meta-analysis, for each 5-μmol/L increment of tHcy levels, the risk for all-cause mortality increased by 33.6%.[4]The ankle-brachial index (ABI) is an effective, well-established measure that is commonly used in the diagnosis of peripheral artery disease (PAD),[5] meanwhile was well studied as an important indicator of atherosclerosis and CVD events.[6] Although ankle-brachial index (ABI) ≤ 0.90 has been recognized as the threshold value for abnormal/low ABI, which was proven to increase the risk of all-cause mortality,[7] a study from the American Heart Association has suggested ABI between 0.91 and 1.00 should be considered as “borderline area” in terms of cardiovascular risks,[8] considering of prior probability and sensitivity of ABI calculation. Emerging studies have aimed to explore the predictive value of borderline ABI,[9-11] however, controversy remains because of limited and inconsistent data. The current study aimed to explore the individual and joint effect of borderline ABI and tHcy on all-cause mortality among hypertensive adults. Although ABI level ≤ 0.90 has been and is going to remain significant in clinical practice, we believe broader concern should be placed on borderline ABI, especially for its value in risk differentiation and identification. To the best of our knowledge, there are no similar previous studies. 相似文献

目的 探讨肾透明细胞癌中血管内皮生长因子(VEGF)表达及微血管密度(MVD)的临床病理意义.方法 应用免疫组织化学方法检测VEGF蛋白表达,通过CD34抗体标记血管内皮来计算MVD值.结果 66例肾透明细胞癌VEGF蛋白表达阳性率为54.5%(36/66),其表达强弱与肿瘤分级、大小、分期等无显著相关性.MVD值为12~96.3,与肿瘤分级(P=0.005)、分期(P=0.000)相关,分级高、分期晚的透明细胞癌MVD值比分级低、分期早的低.有转移的肾透明细胞癌MVD值低,没有转移者MVD值高,差异有统计学意义(P=0.011).肿瘤体积较大时MVD50的病例(26.7%)明显少于MVD<50的病例(73.3%).VEGF和MVD值均与肾被膜累及情况无关,二者之间亦无相关性.结论 VEGF在肾透明细胞癌中的高表达,使得其可能成为治疗的靶向分子.透明细胞癌中MVD值与分级和分期呈负相关,可能有一定预后意义. 相似文献

研究肝细胞癌组织中p27表达对细胞增殖与凋亡活性的影响.采用Elivision法检测47例肝癌及相应癌旁肝组织中p27及PCNA的表达,TUNEL法检测原位细胞凋亡.结果显示肝癌组织中细胞增殖与凋亡指数明显高于癌旁肝组织.肝癌组织中p27染色指数明显低于癌旁肝组织与正常肝组织.低分化肝癌组织中p27表达和凋亡指数均明显降低.存在肝外转移的肝癌组织中p27表达降低而增殖指数明显增高.进一步研究显示,p27高表达组肝癌组织中凋亡指数明显高于低表达组,而增殖指数却显著降低.提示p27蛋白表达降低与肝癌的发生和进展有着密切关系,并可能是导致肝癌细胞增殖凋亡失衡的因素之一. 相似文献

新版全球哮喘防治创议(GINA)方案的评价和解读 总被引:11,自引:0,他引:11
1993年美国国立卫生院心肺血液研究所(NHLBI)联合世界卫生组织(WHO)成立了"全球哮喘防治创议"专家组,并于1995年出版了一套名为《全球哮喘防治的创议》(Global Initiative for Asthma,GINA)系列丛书.这套丛书的出版为哮喘的管理和预防提供了全面和系统的方案.2002年及此后每年,专家组会对GINA内容进行更新.2006年GINA的更新是基于2005年1月以来的大量临床研究做出的.所以GINA2006提供了更多的参考信息,更为实用,更易操作. 相似文献
