Background

Ginger (Zingiber officinale) is a well known and extensively used antioxidant in traditional remedies. In this study, we aimed to investigate the effects of ginger powder on ovarian folliculogenesis and implantation in rats.

Methods

There were two study groups. In the 5-day treatment group (one estrous cycle), 100 mg ginger powder, 200 mg ginger powder or distilled water was given for 5 days to the three subgroups each containing seven rats. In the 10-day treatment group, same doses were given for 10 days (two estrous cycle) to the three subgroups each containing seven rats. At the end of the 5th and 10th days, ovarian volumes, ovarian weights, primordial follicles, antral follicles, atretic follicles, and corpus luteum counts were assessed. To evaluate the angiogenic effects of ginger, vascular endothelial growth factor (VEGF) and for the antioxidant effects of ginger endothelial nitric oxide synthase (eNOS) were examined in the ovaries and in the endometrium immunohistochemically.

Results

In the 5-day treatment group, antral follicle count and ovarian stromal VEGF were significantly high in the 100 mg ginger subgroup in comparison to the control group (p < 0.05). In the 10-day treatment group, endometrial VEGF and ovarian stromal eNOS were significantly high in the 100 mg ginger subgroup in comparison to the control group (p < 0.05). There was no statistically significant difference at 200 mg ginger dose both in 5-day and 10-day treatment groups.

Conclusion

The increases in the antral follicle count and ovarian stromal VEGF in the 100 mg/5-day treatment subgroup indicate that ginger have positive effects on folliculogenesis in short term with low dose. Additionally, ginger may enhance implantation in rats in long term with low dose.  相似文献

目的 应用超声新技术及Ki67等指标研究与Graves病(GD)患者131I治疗后甲亢未愈或复发的相关因素。方法 研究2020年1月~2021年11月在我院核医学科接受131I治疗的GD患者89例。随访结局分为甲状腺功能亢进(甲亢)未愈或复发、早发甲状腺功能减退(早发甲减)和甲状腺功能正常或失随访。131I治疗后1个月为随访开始,每位患者最长随访时间为1年。治疗前应用三维超声自动测量技术、剪切波弹性成像技术和超声引导下细针穿刺抽吸技术,获取患者甲状腺容积、腺体剪切波弹性值和滤泡上皮细胞Ki67表达情况。并纳入年龄、病程、用药史、131I治疗剂量、TRAb等因素。应用竞争风险模型分析患者发生甲亢未愈或复发的相关因素并计算其调整风险比(HR)和95%置信区间(95% CI)。结果 在89例GD患者中,出现甲亢未愈或复发的患者有27例,早发甲减患者有50例,甲状腺功能恢复正常的患者1例,失随访11例。竞争风险模型分析显示Ki67表达、131I治疗剂量及甲状腺容积与治疗后甲亢未愈或复发存在独立关联,其HR(95% CI)分别为0.36(0.15,0.86)、0.81(0.68,0.96)和1.11(1.07,1.15)。结论 Graves病患者甲状腺滤泡上皮细胞Ki67表达阳性、131I治疗剂量及甲状腺容积与131I治疗后甲亢未愈或复发存在独立关联。超声新技术可以在评估GD患者131I治疗结局中发挥重要作用。  相似文献

Purpose

Cardiovascular disease (CVD) due to atherosclerosis is the leading cause of early mortality and morbidity. The current European guidelines on CVD prevention in clinical practice recommend the use of the Systematic Coronary Risk Estimation (SCORE) system. The current American Heart Association guidelines recommend the use of the new pooled cohort risk assessment equations to estimate the 10-year atherosclerotic CVD risk. The purpose of this article was to investigate the compliance of dyslipidemia guidelines in daily practice in patients with dyslipidemia or who have risk factors for CVD.

Methods

The study group consisted of 500 outpatients who had dyslipidemia or risk factors for CVD. The risk level was computed according to the European and American Heart Association guidelines. Therapeutic LDL-C targets were identified based on the calculated risk level. Therapeutic target levels were compared based on the dosage of statins used and achievement of the LDL-C goal in daily practice according to the risk levels.

Findings

According to the European dyslipidemia guidelines, 231 patients were in the very-high/high-risk group, and 106 patients (45.9%) achieved the LDL-C target (<100 mg/dL); 210 patients were in the moderate-risk group, and 156 (74.3%) patients achieved the LDL-C target (<115 mg/dL); and 59 patients were in the low-risk group, and 55 (93.2%) patients achieved the LDL-C target (<155 mg/dL). Univariate and multivariate logistic regression analyses revealed that the LDL-C level and presence of coronary artery disease were significantly reverse associated with achievement of the LDL-C goal (both, P < 0.001).

Implications

Our results showed that the majority of patients were in the very-high/high-risk group in daily practice. Although the European dyslipidemia guidelines are more likely to be used in daily practice, achievement of the guidelines-recommended treatment goals was low.  相似文献

In this report, we evaluated the cardiac findings of 15 children with polyarteritis nodosa. The age range of the patients was 4–14 years; with a mean of 10 years. All have had systemic involvement of the disease. The most common findings in cardiac evaluation were diminished left ventricular systolic functions and mild mitral and/or tricuspid valve regurgitation. One patient had pericardial thickening with no effusion. One had sinus tachycardia. There were no signs of myocardial infarction or ischemia clinically or electrocardiographically. In conclusion, we did not find cardiac complications, such as pericarditis or myocardial infarction, to be as frequent as in previous reports. However, even in asymptomatic patients, systolic dysfunction or valvular involvement were common findings in patients with polyarteritis nodosa, which were not reported previously. These findings may be due to the histological changes of the myocardium or atrioventricular valves. Although these were not severe and fatal lesions, long-term follow-up of these patients with echocardiography may help to determine the course of cardiac involvement.  相似文献

Our aim was to investigate the effects of hyaluronan on inflammatory cytokines in the synovial fluid of patients with knee osteoarthritis. The study was single blind, placebo-controlled, and randomized. We administered hyaluronan to 22 patients in the study group and placebo to 19 in the control group. Enzyme-linked immunosorbent assay was used to determine the levels of cytokines. Both HA and placebo caused a significant decrease in interleukin (IL)-6 levels (P=0.0001 and P=0.04, respectively). But it was more significant in the study group. However, IL-8 and tumor necrosis factor alpha (TNF-) levels did not change in either group (P>0.05). The amount of effusion decreased significantly in the study group (P=0.001) but not in the control group (P=0.133). It can be concluded that hyaluronan considerably decreased IL-6 levels, which correlated with clinical improvement, but had no effect on IL-8 and TNF- levels in synovial fluid. However, larger studies with longer follow-up periods are needed to explain the effect of hyaluronan on cytokines.  相似文献

Treatment with convalescent plasma has been shown to be safe in coronavirus disease in 2019 (COVID-19) infection, although efficacy reported in immunocompetent patients varies. Nevertheless, neutralizing antibodies are a key requisite in the fight against viral infections. Patients depleted of antibody-producing B cells, such as those treated with rituximab (anti-CD20) for hematological malignancies, lack a fundamental part of their adaptive immunity. Treatment with convalescent plasma appears to be of general benefit in this particularly vulnerable cohort. We analyzed clinical course and inflammation markers of three B-cell-depleted patients suffering from COVID-19 who were treated with convalescent plasma. In addition, we measured serum antibody levels as well as peripheral blood CD38/HLA-DR-positive T-cells ex vivo and CD137-positive T-cells after in vitro stimulation with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-derived peptides in these patients. We observed that therapy with convalescent plasma was effective in all three patients and analysis of CD137-positive T-cells after stimulation with SARS-CoV-2 peptides showed an increase in peptide-specific T-cells after application of convalescent plasma. In conclusion, we here demonstrate efficacy of convalescent plasma therapy in three B-cell-depleted patients and present data that suggest that while application of convalescent plasma elevates systemic antibody levels only transiently, it may also boost specific T-cell responses.  相似文献
