丹红注射液联合玻璃酸钠关节腔内注射对胫骨骨折患者血清骨性标志物水平的影响

目的:研究丹红注射液联合玻璃酸钠关节腔内注射对胫骨骨折术后血清骨性标志物水平的影响。方法:研究对象选取我院2015年5月到2016年8月间收治的胫骨骨折患者110例,所有患者均行切开复位内固定手术治疗。采用随机数字法将其分为对照组和观察组,每组各55例。对照组患者玻璃酸钠关节腔内注射治疗,观察组患者配合丹红注射液。比较两组患者的治疗疗效、治疗前后的视觉模拟评分法(VAS评分)、血清骨钙素(bone Glaprotein,BGP)、I型前胶原羧基端肽(carboxyterminal propeptide of type I procollagen,PICP)水平的变化。结果:治疗后1、3、7天患处疼痛VAS评分均明显低于对照组(P0.05),治疗后1、2、4周观察组患者关节活动度评分均明显高于对照组(P0.05),治疗后观察组患者血清BGP、PICP水平均明显高于对照组(P0.05)。结论:丹红注射液联合玻璃酸钠关节腔内注射能够促进胫骨骨折术后骨折愈合,提高临床疗效。可能与其有效提高患者血清BGP、PICP水平有关。     

The effect of the menstrual cycle on collagen metabolism,growth hormones and strength in young physically active women

This study aimed to investigate the effect of the menstrual cycle on strength, functioning of the GH/IGF-1 axis and collagen metabolism in physically active women. Twenty-four physically active and eumenorrheic women volunteered to participate in the study (body mass 60.3 ± 9.18 kg, age 21.8 ± 0.92 years). Blood samples were obtained between the 5th and 8th days (the follicular phase) and between the 19th and 22th days (the luteal phase) of the menstrual cycle to determine sex steroid concentrations (follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), oestradiol (E2) and progesterone (P)). Also insulin-like growth factor 1 (IGF-1) and collagen metabolism markers (synthesis (PICP) and breakdown (ICTP)) and maximum voluntary contraction (MVC) were measured. MVC was higher in the luteal phase 164.1 ± 34.77 [N m] (F(1.23) = 4.59; p = 0.043). The recorded collagen synthesis marker (PICP = 296.4 ± 35.61 [ng/ml]) was at the upper level of the reference range (30–300), with an insignificant decrease in the luteal phase (Z = 1.612; p = 0.107) and a significant increase in oestradiol concentration (Z = 4.286; p = 0.0001). The marker of collagen breakdown (ICTP = 4.16 ± 0.68 [μg/l]) was reduced by 6.8% in the same phase (Z = 1.764; p = 0.137). The variability of physical abilities (MVC) during the menstrual cycle showed that menstrual status should be taken into account in determination of the training loads. Increasing the load in the luteal phase seems to be favoured by a beneficial change in collagen metabolism (lower synthesis decrease, lower breakdown increase) observed in physically active women.
