成功建立了人增生性瘢痕细胞和正常皮肤成纤维细胞的原代培养,并利用热休克蛋白(HSP47)和成纤维细胞特异蛋白(FSP)标记物进行了鉴定。研究发现,经过壳聚糖衍生物处理,人增生性瘢痕成纤维细胞和正常皮肤成纤维细胞在培养中均出现了不同类型的蛋白表达。多功能转录因子蛋白(CTCF)在壳聚糖衍生物处理的增生性瘢痕成纤维细胞中出现表达上调;在聚糖衍生物处理的正常皮肤成纤维细胞中数量无变化。YB-1结合蛋白在经壳聚糖处理的正常皮肤成纤维细胞与人增生性瘢痕细胞中的表达几乎无异,但在未经壳聚糖处理的细胞中表达不同。C-MYC和P53蛋白在壳聚糖衍生物处理的增生性瘢痕纤维细胞中表达上调,但在正常皮肤成纤维细胞中,无论是否经过壳聚糖衍生物处理,这两种蛋白都没有表达。上述4种蛋白在人增生性瘢痕细胞和正常皮肤成纤维细胞中表现出不同的表达方式,这种新型壳聚糖衍生物可能在控制人增生性瘢痕细胞和正常皮肤成纤维细胞生长和增殖过程中起着重要作用。这些蛋白因子的表达机制目前还不是完全清楚,有待于进一步研究。

[Objectives] The aim was to study the effects of humic acid and DMPP on the growth of maize and explore the appropriate added concentration to provide basis for industrial production. [Methods]The pot experiment was used to study the effects of adding different concentrations of humic acid,DMPP and their compound on the growth of maize. [Results] Both humic acid and DMPP could increase plant height,stem diameter,SPAD and biomass of maize. The effect of adding 10 kg of humic acid per t was better than that adding 5 kg,and biomass increased by 5. 4% and 3. 3% compared with CK. The effect of adding 1 kg of DMPP was better than that adding 0. 5 kg,and biomass increased by 5. 7% and 2. 7% compared with CK. The compound application of the 2 improved the fertilizer efficiency. The best treatment was 5‰ humic acid ＋ 1 ‰ DMPP,which could increase plant height,stem diameter,SPAD,and dry weight by 8. 1%,12. 3%,10. 6%,and 10. 7%,respectively,and it also had lower economic costs compared with the compounding application of 10‰ humic acid ＋ 1‰ DMPP.[Conclusions]The 5‰ humic acid ＋ 1 ‰ DMPP compound fertilizer formula was more suitable for application in maize production.

2195铝锂合金在工业生产中应用广泛,不同的初始热处理状态影响其热变形行为。因此,本文旨在研究热处理状态对2195铝锂合金的组织演变和热变形行为的影响。实验在Gleeble-3800热模拟机上进行,温度范围为350~500℃,应变速率为0.01~10 s^(-1)。将热变形后各区域的微观组织进行对比,并计算出合金的本构模型和加工图。在较高的变形温度(400~500℃)下,T3和T8试样的峰值应力基本相同,同时发现热变形后合金中存在低角度晶界(LABs)和动态再结晶。由于固溶强化和形变强化作用,2195-T8铝锂合金表现出比2195-T3铝锂合金更大的形变激活能。本文确定2195-T3和2195-T8铝锂合金的最佳热加工条件均为475~500℃和0.01~0.1 s^(-1)。本文可为铝锂合金在后续热加工过程中设置热处理参数提供有益的帮助。

Osteosarcoma (OS) tissue resection with distinctive bactericidal activity, followed by regeneration of bone de-fects, is a highly demanded clinical treatment. Biodegradable Mg-based implants with desirable osteopromotive and superior mechanical properties to polymers and ceramics are promising new platforms for treating bone-related diseases. Integration of biodegradation control, osteosarcoma destruction, anti-bacteria, and bone defect regeneration abilities on Mg-based implants by applying biosafe and facile strategy is a promising and challenging topic. Here, a black Mn-containing layered double hydroxide (LDH) nanosheet-modified Mg-based implants was developed. Benefiting from the distinctive capabilities of the constructed black LDH film, including near-infrared optical absorption and reactive oxygen species (ROS) generation in a tumor-specific microenvi-ronment, the tumor cells and tissue could be effectively eliminated. Concomitant bacteria could be killed by localized hyperthermia. Furthermore, the enhanced corrosion resistance and synergistic biofunctions of Mn and Mg ions of the constructed black LDH-modified Mg implants significantly facilitated cell adhesion, spreading and proliferation and osteogenic differentiation in vitro, and accelerated bone regeneration in vivo. This work offers a new platform and feasible strategy for OS therapeutics and bone defect regeneration, which broadens the biomedical application of Mg-based alloys.

Autonomic innervation of heart is abnormal in diabetes and produces altered cardiovascular parameters. Cerebrolysin is a neurotrophic factor that improves the dendritic tree and synapses in the central nerve system after brain damage. The aim of this study was to evaluate if cerebrolysin can improve the cardiac neuropathy generated in diabetic rats. Male Sprague-Dawley rats two months old were injected with streptozotocin (70 mg/Kg/, ip). Hyperglycemia and altered cardiac rate were confirmed after eight weeks of STZ injection, and cerebrolysin treatment was started in control and diabetic rats for two months (1 ml/kg/day, ip). Body weight, heart rate, heart rate variability, arterial blood pressure, and blood glucose levels were measured. Also heart weight and levels of nitrites, NGF and VEGF were measured in left ventricle homogenates. The results show that body weight was reduced and blood glucose levels were increased significantly in diabetic rats. Cerebrolysin treatment produced no significant changes in body weight either in blood glucose level in control and diabetic rats. Cerebrolysin treatment in diabetic rats shows an improvement in the altered basal cardiac rate (306 ± 6.5 lat/min) compared to diabetic saline group (272 ± 8.9 lat/min: P treatment to prevent or reduce the cardiac autonomic alterations generated in diabetes.
