It has been reported that prenatal undernutrition affects the development of the peripheral immune system. In this study, the effects of prenatal undernutrition on the febrile response and hypothalamic innate immune system were evaluated in male rats. Pregnant rats were divided into normally nourished (NN) and undernourished groups (UN). The febrile and anorectic responses to lipopolysaccharides (LPS) were evaluated in the offspring of NN and UN dams. The hypothalamic expression levels of pro-inflammatory cytokines, toll-like receptor 4 (TLR4), and neuropeptide Y (NPY) were also evaluated. The UN rats exhibited significantly lighter body weights than the NN rats at birth; however, their mean body weight was the same as that of the NN rats by postnatal day 10. In adulthood, the UN rats exhibited significantly stronger febrile responses than the NN rats, and the anorectic responses of the UN rats also tended to be stronger than those of the NN rats. On the other hand, no differences in hypothalamic interleukin (IL)-1β, IL-6, tumor necrosis factor-α, TLR4, or NPY mRNA expression were detected between the NN and UN rats. These results suggest that prenatal undernutrition has long-lasting effects on the febrile response to LPS. However, the precise mechanism underlying these effects and their pathophysiological significance remain unclear. 相似文献

目的观察飞秒激光小切口角膜基质透镜取出术(SMILE)术后超早期患者视觉质量变化,探讨其变化发生的可能原因。方法选取中低度近视患者23例46眼行SMILE术,术前及术后24 h超早期行主观视觉质量问卷,测量最佳矫正视力的全程视力(远视力5 m,中视力60 cm,近视力33 cm)、对比敏感度(CS)、眩光敏感度(GS)及集合近点(NPC)和调节幅度(AA)。结果视觉质量主观问卷显示术后超早期主观视觉质量较术前下降(P=0.001)。术后裸眼视力(UCVA)明显提高(P=0.0001)。术前与术后最佳矫正视力(BCVA)中远视力没有变化(P=0.096),而中视力和近视力均较术前下降(P=0.039,0.003)。术后CS、GS降低(PCS=0.0001,PGS=0.04),NPC、AA较术前无明显变化(P=0.68,0.13)。结论SMILE术后超早期患者可获得预期理想远视力,但中、近视力尚未恢复。超早期中出现的异常视觉质量改变可能与对比敏感度和眩光敏感度的改变有关。 相似文献

PurposeBreast cancer is the most common cancer diagnosed during childbearing age, and fertility preservation is becoming increasingly more essential. However, recent studies indicate a possible poorer response to controlled ovarian hyperstimulation (COH) in cancer patients than in non-cancer controls and a negative impact of BRCA mutations on female fertility. This study aims to evaluate ovarian response and the number of mature oocytes (MII) vitrified in women with breast cancer, with or without BRCA mutation, comparing them to the expected response according to an age-related nomogram.MethodsThis is a retrospective observational study involving sixty-one breast cancer patients who underwent COH for oocyte cryopreservation. The age-specific nomogram was built using 3871 patients who underwent COH due to oocyte donation, fertility preservation for non-medical reasons, or FIVET for male factor exclusively.ResultsThe mean number of oocytes retrieved was 13.03, whereas the mean number of MII oocytes was 10.00. After the application of the z-score, no statistically significant differences were found compared with the expected response in the general population, neither by dividing patients according to the presence or absence of BRCA mutation nor according to the phase in which they initiated stimulation.ConclusionThe results obtained do not support the notion of a negative impact of the BRCA mutation on the ovarian response of women with breast cancer. Women with breast cancer undergoing COH for fertility preservation can expect the ovarian response predicted for their age. 相似文献

目的:讨论普通变异型免疫缺陷病(common variable immunodeficiency disease,CVID)的发病机制、临床表现及治疗方法。方法:报道1例普通变异型免疫缺陷病合并肝硬化患者并复习相关文献。结果:普通变异型免疫缺陷病是临床少见病,易误诊,病因不清,临床表现复杂,部分患者病程中可出现肝功能异常,甚至并发肝硬化。结论:临床反复感染的患者应考虑CVID的可能,须进一步作血浆免疫球蛋白的检测确诊。对已经确诊患者定期补充静脉丙种球蛋白,同时还应定期检查肝功能。 相似文献

Epilepsy is a common neurologic disorder, which is efficiently treated with carbamazepine and valproic acid. Moreover, Saudi Ministry of Health implemented a new E-system for Poison Control Centers called Awtar to enhance technology utilization in ensuring patients’ satisfaction and to improve treatment outcomes. Therefore, we conducted this study to assess appropriateness of indication of requests and therapeutic levels of carbamazepine and valproic acid in Tabuk area, North West Saudi Arabia. This is a retrospective observational study conducted in Poison Control & Forensic Chemistry Center, Tabuk, Saudi Arabia. Patients’ data were obtained for years 2018 and 2019. The blood levels of carbamazepine and valproic acid were measured by Therapeutic Drug Monitoring (TDM) Unit. We selected patients treated with either valproic acid or carbamazepine alone without any history of drug allergy. Data of 264 patients were extracted from Awtar E-system. Serum carbamazepine levels were within therapeutic range in 114 patients (75.50%), above-therapeutic range in 13 patients (8.61%) and sub-therapeutic levels in 24 patients (15.89%). Regarding serum valproic acid, it is within therapeutic range in 62 patients (54.87%), above-therapeutic range in 11 patients (9.73%) and sub-therapeutic levels in 40 patients (35.40%). In conclusion, this study gives information about partial appropriateness of usage of carbamazepine and low level of appropriateness of valproic acid. However, more efforts are needed to improve results of appropriateness of indication of antiepileptic drugs. 相似文献
