    • 摘要: 背景:排汗可将一些溶解于汗液的代谢产物带出体外,在排泄中起辅助作用。现代医学目前还无法恢复严重创伤或烧伤患者的汗腺,如何解决皮肤汗腺的再生及如何培养具有皮肤附属物的“功能性组织工程皮肤”问题已成为当今医学研究中的热点。目的:探讨机体的新陈代谢、汗液的代谢方式,分析组织工程皮肤功能性附属物汗腺再生研究的现状。方法:收集组织工程皮肤功能性附属物再生,特别是排汗的相关研究,分析机体的新陈代谢与排泄方式,汗液代谢的物质和方式,以及目前组织工程皮肤附属物汗腺再生研究的现状。结果与结论:汗液作为排泄系统中重要的一员在维持机体内部的动态平衡,防止代谢产物对身体的损害方面具有不可忽视的地位。理想的功能性组织工程皮肤应具有分泌汗液、排泄废物、调节体温和维持皮肤动态平衡的作用,在大面积烧伤后皮肤创伤修复和重建过程中起着至关重要的作用。已有研究将干细胞与汗腺细胞进行共培养,然后移植到瘢痕创面上进行重建汗腺组织,取得了一定的成功。

    • 摘要: 背景:成骨细胞体外培养及其中药干预是研究和开发中药治疗骨质疏松症的重要手段之一。目的:观察中药对成骨细胞增殖、分化及对骨钙素合成的影响。方法:收集不同类别中药载药血清对体外成骨细胞及骨钙素分泌影响的相关研究,进行实验数据分析,从细胞分子生物学水平认识传统中药影响成骨细胞合成骨钙素的作用。结果与结论:部分单味中药和中药复方有促进成骨细胞增殖、分化及骨钙素的合成作用,并且不同中药成分对成骨细胞增殖和分化的促进作用及提高骨钙素表达水平不同,与这种中药载药血清浓度在一定范畴内呈正相关。通过对成骨细胞体外培养方法的筛选,找出促进细胞增殖和分化的药物及适宜剂量,对研制治疗骨质疏松症的药物具有积极促进作用。%BACKGROUND: In vitro culture of osteoblasts and its Chinese medicine intervention is one of the important means for the research and development of osteoporosis treated with traditional Chinese medicine. OBJECTIVE: To observe the effect of Chinese medicine on the proliferation and differentiation of osteoblasts and the synthesis of osteocalcin. METHODS: The researches on the effect of different kinds of Chinese medincine-loaded serum on the secretion of osteoblasts and osteocalcin were col ected for the data analysis. The effect of traditional Chinese medicine on osteocalcin synthesis of osteoblasts was observed from the level of molecular cel biology. RESULTS AND CONCLUSION: Some single Chinese herbs and Chinese herbal compounds could promote the proliferation and differentiation of osteoblasts and the synthesis of osteocalcin, and different Chinese medicines had different effects in promoting the proliferation and differentiation of osteoblasts and expression level of osteocalcin, which was positively correlated with the concentration of Chinese medicine-loaded serum. Through screening with the in vitro culture of osteoblasts, the drugs and appropriate dose for promoting the proliferation and differentiation were founded, which could positively promote the development of drugs used for the treatment of osteoporosis.

    • 摘要: BACKGROUND: Many congenital and acquired anomalies can lead to a defect or stenosis of the urinary tract that ultimately need to be rebuilt. Past surgical repair often utilizes skin, oral mucosa or autologous graft, which may lead to many postoperative complications. The development of tissue engineering technology has opened up a new treatment approach for urethral repair and reconstruction. OBJECTIVE: To summarize the current development of scaffold materials, cellsources, and the clinical applications of tissue engineering technology in urethral repair and reconstruction.METHODS: A computer-based online search of literatures related to urethral tissue engineering from January 1994 to may 2012 was performed by the first author in PubMed database and Wanfang database using the key words of “tissue engineering, urethra, scaffold materials, stem cells, vascularization” in English and in Chinese. Literatures published in the authorized journals or recently were preferred. A total of 57 literatures were chosen in result analysis. RESULTS AND CONCLUSION: The main goals underlying the most current research in tissue engineering remain the fol owing: the determination of the optimal scaffold for cellseeding, the best source of stem cells, and the promotion of neovascularization and nerve regeneration into the implant. Studies addressing urethral tissue engineering have demonstrated that acel ular scaffolds with or with no seed cells can be used for urethral reconstructions in clinical trials. While continued development and additional innovation are necessary before potential broad applications are realized, there is cautious optimism that tissue engineering technology wil play an increasing role in the management of urethral diseases.%  背景:多种疾病或创伤可导致尿道组织的缺损或狭窄,需用其他组织来修复与重建。传统应用包皮、口腔黏膜,或者其他自体移植物修复会带来较多并发症,而组织工程的兴起为尿道修复与重建开辟了新的治疗思路。目的:总结并探讨组织工程支架材料的选择、种子细胞的选择,以及目前组织工程在尿道修复中的临床应用情况。方法:由第一作者应用计算机检索 PubMed 数据库及万方全文数据库1994年1月至2012年5月有关尿道组织工程的文章,英文检索词为“Tissue engineering, urethra, scaffold materials, stem cel s, Vascularization”,中文检索词为“组织工程;尿道;支架材料;干细胞”。排除重复性研究,共保留57篇文献进行综述。选择文章内容主要为组织工程支架在尿道修复中的应用情况,同一领域文献则选择近期发表或发表在权威杂志文章。结果与结论:目前组织工程研究的主要目标仍旧是以下几点:选择最佳支架、最佳干细胞来源,促进移植物新生血管和神经长入。泌尿系统组织工程已经报道,在临床上,使用复合或者不复合种子细胞的脱细胞支架可以重建尿道。虽然在大规模应用于临床前,还需要进一步的研究和创新,有理由期待组织工程会在尿道疾病中发挥越来越大的作用。

    • 摘要: BACKGROUND: Osteocytes that form a three-dimensional cel ular network inside the mineralized bone matrix are a critical regulator of bone metabolism. OBJECTIVE: To explore the progress in studies of osteocytes effect on bong remodeling. METHODS: The articles on the role of osteocytes and bone remodeling were searched by computer in the PubMed and ELSEVIER databases from January 1990 to April 2012 using the key words of “osteocytes,remodeling”. Meanwhile, Wanfang database was retrieved to identify the related articles published between January 1990 and April 2012 with the keywords of “osteocytes, remodeling” in Chinese. After the ful texts on the subject were founded, 41 articles were chosen and summarized. Repetition and analogous researches were excluded. RESULTS AND CONCLUSION: Osteocytes that sense and response to mechanical stress play a critical role in bone remodeling, including initiating bone remodeling, inhibiting bone resorption and control ing bone formation. Studies have demonstrated that osteocyte synapses can serve as the direct receptor for stress-induced cel deformation. After stress stimulation, osteocytes can activate the Wnt/Lrp pathway serving as a negative regulator of hardened protein that is a negative regulator of bone formation, and osteocytes also play a role in the control of bone matrix fil ing during bone remodeling.%  背景:骨细胞在骨组织中形成遍布矿化骨基质的三维细胞网络,可以作为骨代谢重要的调节因子。目的:分析讨论骨细胞在骨重建过程中功能的研究进展。方法:应用计算机检索 PubMed 数据库、ELSEVIER 数据库1990年1月至2012年4月有关骨细胞功能及骨重建的文章,检索词“osteocytes,remodeling”。同时检索万方数据库1990年1月至2012年4月相关文章,检索词“骨细胞,骨重建”。选出有代表意义的41篇进行归纳总结,排除重复或类似的同一研究。结果与结论:骨细胞对于应力的感受与反应使得骨细胞在骨重建中发挥着重要的作用,包括骨重建的启动、骨吸收抑制以及骨形成的调节。研究表明骨细胞的突触可能作为应力造成细胞变形的直接感受器。实验证明骨细胞受应力刺激后可能激活 Wnt/Lrp 通路作为硬化蛋白的负调节因子,而硬化蛋白本身是骨形成的负调节因子,骨细胞在重建过程中可能还承担着控制骨基质填充速度的角色。

    • 摘要: BACKGROUND: Perspiration can remove some metabolites dissolved in the sweat out of the body, playing a supporting role in the excretion. Modern medicine cannot restore the sweat glands of severe trauma or burn patients, and how to solve the regeneration of the skin and sweat glands and culture tissue-engineered skin functional appendage has become a hot spot in today’s medical research. OBJECTIVE: To explore the body’s metabolism and metabolic way of the sweat, thereby analyzing the functional sweat gland regeneration of tissue-engineered skin. METHODS: Studies addressing the tissue-engineered skin functional appendage regeneration effects on perspiration and metabolism were col ected to analyze the body’s metabolism and excretion ways, sweat metabolites and metabolism methods, as wel as the regeneration of tissue-engineered skin appendages. RESULTS AND CONCLUSION: Sweat as an important member in the excretory system cannot be ignored in maintaining the dynamic equilibrium of the body and preventing the body against metabolite damages. Ideal tissue-engineered skin functional appendages have abilities of sweat secretion, excretion of waste, regulating body temperature and maintaining the dynamic equilibrium of the skin, thereby playing a vital role in skin wound repair and reconstruction after extensive burns. Studies have shown that stem cells and sweat gland cells were co-cultured, and then transplanted into the scar wound for sweat gland reconstruction, which has achieved some success.%  背景:排汗可将一些溶解于汗液的代谢产物带出体外,在排泄中起辅助作用。现代医学目前还无法恢复严重创伤或烧伤患者的汗腺,如何解决皮肤汗腺的再生及如何培养具有皮肤附属物的“功能性组织工程皮肤”问题已成为当今医学研究中的热点。目的:探讨机体的新陈代谢、汗液的代谢方式,分析组织工程皮肤功能性附属物汗腺再生研究的现状。方法:收集组织工程皮肤功能性附属物再生,特别是排汗的相关研究,分析机体的新陈代谢与排泄方式,汗液代谢的物质和方式,以及目前组织工程皮肤附属物汗腺再生研究的现状。结果与结论:汗液作为排泄系统中重要的一员在维持机体内部的动态平衡,防止代谢产物对身体的损害方面具有不可忽视的地位。理想的功能性组织工程皮肤应具有分泌汗液、排泄废物、调节体温和维持皮肤动态平衡的作用,在大面积烧伤后皮肤创伤修复和重建过程中起着至关重要的作用。已有研究将干细胞与汗腺细胞进行共培养,然后移植到瘢痕创面上进行重建汗腺组织,取得了一定的成功。
