Effects of kidney-tonifying and blood circulation-promoting recipes and platelet-rich plasma on the activity and expression of type I collagen

Objective:To observe the effects of kidney-tonifying and blood circulation-promoting recipes and platelet-rich plasma(PRP)on the activity and expression of type I collagen in co-culture system.Methods:The subcutaneous adipose tissue and degenerative nucleus pulposus tissue of patients with nucleus pulposus removal under lumbar intervertebral disc degeneration were isolated and cultured by multiple enzyme digestion methods to establish a co-culture system of ADSCs/NPCs.Patients with lumbar intervertebral disc degeneration were enrolled for 2 weeks.The venous blood was taken 50mL before the first dose and one hour after the last dose.Platelet-rich plasma was prepared by secondary centrifugation and cultured with different plasma.The experiment was divided into five groups:platelet-rich plasma group(PRP),platelet-poor plasma group(PPP),drug-rich platelet-rich plasma group(M-PRP)and drug-poor platelet plasma group(M-PPP),fetal bovine serum group(FBS).The morphological changes of the cells in each group were observed under an inverted microscope.The changes of type I collagen activity were detected by immunofluorescence assay.The expression of CCOL1A1 gene was detected by RT-PCR two weeks after the intervention.Results:In this study,the results of kidney-tonifying and blood circulation-promoting recipes and PRP group intervention were shown.The results of the group intervention showed that the M-PRP group and the PRP group had clearer cell contours and better refractive index than the other groups,and there was no significant difference between the two groups.The results of immunofluorescence staining showed that the number of cells in PRP group and M-PRP group was higher,but the staining intensity of single cells was significantly lower than that in FBS group.RT-PCR results showed that the expression of COL1A1 mRNA in PPP group,PRP group,M-PRP group and M-PPP group was significantly down-regulated(P<0.05),respectively:0.343±0.040,0.294±0.018,0.310±0.022,0.430±0.020.Conclusions:Kidney-tonifying and blood circulation-promoting recipes combined with platelet-rich plasma can decrease the activity and exhibit a tendency to inhibit the expression of type I collagen.

补肾健脾方药对老年大鼠肝脏衰老有关基因表达的影响

目的:比较补肾、健脾方药对老年大鼠肝脏衰老有关基因表达的调控作用。方法:以自然衰老大鼠为衰老模型,随机分为老年对照组、老年补肾组、老年健脾组,并设青年大鼠对照组。予药物干预4个月后,采用RT-PCR和Western blot方法检测大鼠肝脏抑癌基因p16、抑癌基因p21、细胞周期素D1(Cyclin D1)、增殖细胞核抗原(PCNA)、细胞周期素E(CyclinE) mRNA转录和蛋白的表达。结果:老年大鼠肝脏p16、p21和Cyclin D1 mRNA/蛋白的表达明显增高,而PCNA和Cyclin E mRNA/蛋白的表达明显降低。补肾方药可明显下调肝脏p16和Cyclin D1,上调PCNA和Cyclin E基因mRNA与蛋白的表达;健脾方药能明显下调肝脏Cyclin D1,上调PCNA和Cyclin E基因mRNA与蛋白表达,但对p16作用不明显。结论:补肾、健脾方药均能不同程度调控肝脏衰老有关基因表达,促进老年大鼠肝细胞增殖,但补肾方药作用似更明显。

活血疏风止痒中药外洗联合血液灌流对维持性血液透析患者皮肤瘙痒改善及血液透析充分性指标的影响

目的探讨活血疏风止痒中药外洗联合血液灌流对维持性血液透析患者皮肤瘙痒改善及血液透析充分性指标的影响。方法将2019年8月-2021年8月收治的60例尿毒症期皮肤瘙痒症患者随机分成对照组和观察组,对照组采用血液灌流联合血液透析治疗,观察组在此基础上,联合活血疏风止痒方外洗治疗,2组均连续治疗12周。观察比较2组治疗前后DirkR.Kuypers评分、视觉模拟评分(VAS)、钙磷代谢指标[钙(Ca)、磷(P)、甲状旁腺激素(PTH)]、血液透析充分性指标[尿素氮(Bun)、β2-微球蛋白(β2-MG)、血肌酐(Scr)、Kt/v]变化,并对比2组总有效率和不良反应事件情况。结果治疗后,2组DirkR.Kuypers评分、VAS评分,P、PTH水平,Bun、β2-MG、Scr水平均明显降低(P<0.05),且观察组上述评分和指标水平均明显低于对照组(P<0.05);治疗后,2组Ca水平,Kt/v均明显升高(P<0.05),且观察组该两项指标水平均明显高于对照组(P<0.05);治疗期间及治疗前后2组患者肝功能指标(AST、ALT)、血常规(PLT、HG、WBC)均未发生异常,也均未发生不良反应事件。结论活血疏风止痒中药外洗联合血液灌流能够显著缓解尿毒症皮肤瘙痒症患者临床症状,提高血液透析充分性,促进Bun、Scr、β2-MG等中小分子毒素得到更好的净化,有助于改善本病患者生存质量。
