子宫内膜异位症的激素治疗对卵巢纤维化和卵巢储备的影响

摘要 目的：探讨子宫内膜异位症的激素治疗对卵巢纤维化和卵巢储备的影响。方法：选取2019年9月-2021年8月西安国际医学中心医院收治的86例子宫内膜异位症患者,将其随机分为四组（A、B1、B2、C）,A组未接受任何激素治疗,B1组和B2组接受炔诺酮孕激素治疗,C组接受促性腺激素释放激素（GnRH）治疗。比较四组24个月复发率、复发期间肿瘤直径大小、抗苗勒激素（AMH）和促卵泡激素（FSH）水平以及血清转化生长因子-β1（TGF-β1）和平滑肌肌动蛋白（α-SMA）的表达。结果：与治疗前相比,A组斑点样出血以及痛经情况未发生变化（P>0.05）,B1、B2和C组斑点样出血升高,痛经情况降低（P<0.05）;治疗后,B1、B2和C组较A组斑点样出血升高、痛经情况降低,C组较B1、B2组升高（P<0.05）。与治疗期间对比,四组子宫内膜异位症复发率均发生变化（P<0.05）。在治疗期间,与A组相比,B1组、B2组和C组子宫内膜异位症复发率降低,且B1组、B2组较C组降低;在随访期间,B1组、B2组复发率低于C组（P<0.05）。与治疗期间相比,A组随访期间子宫内膜瘤直径比较无差异（P>0.05）,B1、B2和C组增大（P<0.05）。B1、B2和C组较A组子宫内膜瘤直径减小（P<0.05）,而C组较B1、B2组增大（P<0.05）。与治疗前相比,四组治疗后血清FSH水平升高,血清AMH水平降低（P<0.05）;治疗后,B1、B2和C组较A组血清FSH水平降低,AMH水平升高（P<0.05）。各组治疗后较治疗前TGF-β1和α-SMA的蛋白表达降低（P<0.05）;治疗后B1、B2和C组较A组TGF-β1和α-SMA蛋白表达水平降低（P<0.05）。结论：与GnRH相比,孕激素可能是子宫内膜异位症术后卵巢储备和纤维治疗的更好选择。     

Preparation and Standardisation of Smoke-Water for Seed Germination and Plant Growth Stimulation

Smoke-water (SW) has a positive effect on seed germination in many plant species and its application in various fields of plant science has become popular. The method of preparing SW is relatively easy and inexpensive. However, many researchers working in the field of smoke biology are still unfamiliar with preparing SW and testing it for bioactivity. Thus, the aim of this study was to develop a low-cost efficient apparatus to produce SW using grasses, its standardisation and quantification of major active biomolecules. The prepared crude SW was diluted with distilled water (SW:DW) to 75:25, 50:50 and 25:75 (v/v) and these sub-dilutions were further diluted to 1:500; 1:1000; 1:1500; 1:2000; 1:2500; 1:3000 and 1:3500 (v/v). For the standardisation of SW, lettuce seeds (Lactuca sativa L. cv. Grand Rapids) were tested to determine the best working concentration. The ratio 1:2500 (v/v) from the sub-dilution 25:75 (v/v) of SW was the best for germination of lettuce seeds in the dark, achieving 91% germination against the water control that had only 7–10% germination. This is the first study which reports the levels of stimulatory (karrikinolide 1, KAR₁ and karrikinolide 2, KAR₂) and inhibitory (trimethylbutenolide, TMB) compounds present in SW using ultrahigh-performance liquid chromatography–electrospray positive ionisation tandem mass spectrometry (UHPLC-ESI(+)-MS/MS).

     

Observations upon rhinoceros cervical lymphatics

As an initial contribution to rhinoceros lymphangiology observations are presented upon the disposition of the lymphatic vessels and nodes associated with the larynx, thyroid gland and parathyroid glands of an adult male Indian rhinoceros (Rhinoceros unicornis). A detailed account is given of the topography and connexions of the anterior and intermediate groups of cervical lymph nodes and of the lymph drainage of certain cervical organs. The presence is reported, upon inter-nodal afferent pathways, of specialised and hitherto undescribed formations of a lympho-haemal nature and the functional significance of these is suggested.     

Further Observations on the Effect of Synthetic Thyrotrophin-releasing Hormone in Man

Synthetic thyrotrophin-releasing hormone (TRH) given intravenously in doses of 50 μg or more causes a significant rise in serum thyroid-stimulating hormone (TSH) levels but has no effect on serum growth hormone, plasma luteinizing hormone, or plasma 11-hydroxycorticosteroids under carefully controlled basal conditions.The peak TSH response to intravenous TRH occurs at 20 minutes. The mild and transient side effects, which occur only after intravenous TRH, include nausea, a flushing sensation, a desire to micturate, a peculiar taste, and tightness in the chest. There is considerable variability in response to a given dose of TRH in the same subject on different occasions and in different subjects. Oral administration of TRH in doses of 1 mg and above causes a rise in serum TSH, maximal at two hours, a consistent response being obtained at doses of 20 mg and above. A rise in serum protein-bound iodine (P.B.I.) follows that of TSH, a consistent response being observed at 40-mg doses of TRH orally. Measurements of serum TSH after intravenous administration of TRH or of serum TSH or serum P.B.I. after oral TRH should prove useful tests of pituitary TSH reserve.     

不同年龄大鼠血清抗中肾旁管激素水平与卵巢储备功能的关系

目的探讨不同年龄组雌性大鼠血清抗中肾旁管激素（AMH）变化的规律和原因,探讨AMH在预测卵巢储备功能方面的作用。方法SD雌性大鼠分为幼年组、成年组和老年组。运用ELISA和免疫荧光化学方法,检测血清和卵巢中AMH的表达。结果血清AMH水平,幼年组5.26±0.13 ng/mL,成年组2.34±0.11 ng/mL,老年组0.69±0.04 ng/mL,随年龄增长显著降低（P〈0.001）。卵巢中AMH阳性卵泡的数量,幼年组19.5±1.3,成年组10.8±1.5,老年组3.8±0.6,随年龄增长显著降低（P〈0.001）。结论随着大鼠年龄增长,卵巢中分泌AMH的生长卵泡数量减少,使血清AMH水平下降,提示卵巢储备功能下降。AMH是一个较好的检测卵巢储备功能的指标。
