Due to the high degradation rate, nano-β-tricalcium phosphate is not conducive for the biological tissue to attach on the material in vivo, which is not conducive to osteogenic induction. OBJECTIVE: To observe the bone formation and degradation performances of nano-hydroxyapatite/ nano-β-tricalcium phosphate biphasic ceramic artificial bone. METHODS: Thirty-six Chinchil a rabbits were randomly divided into experimental group, control group and blank group, and the rabbits were used to establish the left radius bone defect model. The rabbits in the experimental group and the control group were implanted with nano-hydroxyapatiteano-β-tricalcium phosphate biphasic ceramic artificial bone and nano-hydroxyapatite artificial bone respectively, and the blank group was not implanted with any materials. The bone formation and degradation performances were observed at 4, 8 and 12 weeks after implantation. RESULTS AND CONCLUSION: X-ray film at 12 weeks after operation showed that the materials in the experimental group were basical y degraded, the continuity cal us grew through the bone defect site; the materials in the control group were not degraded obviously, and there was cal us at the bone defect site; the bone defect in the blank group was not repaired. Histological observation at 12 weeks after operation showed that the material pores in the experimental group were fil ed with bone cells and osteoblasts, as wel as a smal amount of chondrocytes, the scattered cancel ous bone appeared and the materials were completely degraded; the material pores in the control group were fil ed with bone cells, as wel as a smal amount of osteoblasts and chondrocytes, and the materials were not degraded completely; fibrous connective tissue and col agen fibers could be seen in the blank group. Scanning electron microscope observation at 12 weeks after operation showed that in the experimental group, the materials were degraded, and the bone defect sites were replaced with new bone cancel ous bone; materials in the control group were not degraded, and most of the bone defect sites were replaced with new cancel ous bone; no obvious bone reconstruction could be seen in the blank group. The results indicate that nano-hydroxyapatiteano-β-tricalcium phosphate biphasic ceramic artificial bone has good degradation performances.

摘要： BACKGROUND: Heterogeneous tendon is an ideal method to repair tendon defects, but the post-transplantation rejection limits the application of heterogeneous tendons. OBJECTIVE: To investigate the effect of transplantation of 1-ethy1-3-(3-dimethylaminopropy1) carbodi mide hydrochloride cross-linking acel ular tendon of Banna inbred-lines miniature pig for repairing the rabbit Achil es tendon defects. METHODS: Lateral resection of bilateral Achil es tendons from 40 Japanese rabbits was performed, and then the tendons were divided into experimental group and control group. The experimental group was repaired with transplantation of 1-ethy1-3-(3-dimethylaminopropy1) carbodi mide hydrochloride cross-linking acel ular treated tendon of Banna mini-pig inbred-lines, and the control group was repaired with autologous tendon graft. RESULTS AND CONCLUSION: Histological observation showed that the cells in the new tissue of two groups were mainly the mononuclear fibroblast and fibrocytes, and the cells were oval or circular fibroblasts at 1-4 weeks after operation; new col agen formation could be seen around the cells in the cel aggregation area, and the col agen represented disorderly; focal cord-like mature col agen was distributed in island shape and formed the so-cal ed “col agen island”; at 12 weeks after operation, the cells were increasingly elongated and became spindle-shaped and long strip fibroblasts. Laboratory testing showed that there were no significant differences in white blood cells, C-reactive protein levels, hydroxyproline content and tensile strength between two groups. The results show that 1-ethy1-3-(3-dimethylaminopropy1) carbodi mide hydrochloride cross-linking acel ular tendon from Banna mini-pig inbred-lines can repair rabbit Achil es tendon defects successful y with good histocompatibility, less transplant rejection and strong biomechanical performance.%　　背景：异体肌腱移植是目前修复肌腱缺损的理想方法，但移植后的排斥反应使其使用受到限制。目的：观察碳化二亚胺交联改性脱细胞处理的版纳近交系微型猪肌腱移植修复兔跟腱缺损的效果。方法：横向切除40只日本大白兔双侧跟腱，随机分组：实验组以碳化二亚胺交联改性脱细胞版纳近交系微型猪肌腱移植修复，对照组以自体肌腱移植修复。结果与结论：①组织学观察：两组新生组织内细胞主要都是单核的成纤维细胞和纤维细胞，术后1-4周主要是呈椭圆形或圆形的成纤维细胞，细胞聚集区的细胞周围有新生胶原形成，这些胶原的走向较紊乱；局灶性条索状成熟胶原呈岛状分布，形成所谓“胶原岛”；术后12周时细胞越来越拉长，成为梭形和长条形的纤维细胞。②实验室检测：两组白细胞、C-反应蛋白水平、羟脯氨酸含量及抗拉强度差异均无显著性意义。说明碳化二亚胺交联改性的脱细胞版纳近交系微型猪肌腱能成功修复兔跟腱缺损，且具有组织相容性好、移植排斥反应轻、生物力学性能强的优点。

OBJECTIVE: To examine the potential application of a non-viral gene carrier, water soluble lipopolymer (WSLP) for delivering siRNA targeting NR1 in vitro and in vivo and to determine whether WSLP-NR1siRNA complexes can be a new method for neuropathic pain treatment. METHODS: PC12 cells were randomly divided into three groups: group WSLP-negative NR1 siRNA (negative group), group polyethylenimine-NR1 siRNA (control transfection group) and group WSLP- NR1 siRNA (group WS). NR1 expressions were detected using reverse transcription-PCR and western blot analysis. Forty-eight healthy male Sprague-Dawley rats were randomly divided into four groups (n=12 in each group): sham operation group (sham group), neuropathic pain group (model group), group polyethylenimine-NR1 siRNA (group PEI) and group WSLP- NR1 siRNA (group WSLP). Neuropathic pain models were established in the latter three groups. Normal saline, PEI-NR1 siRNA complex and WSLP-NR1 siRNA were injected intrathecal y in model, PEI and WSLP groups, respectively, at 1 day after operation. Only the sciatic nerve was exposed in the sham group. RESULTS AND CONCLUSION: NR1 mRNA and protein expression significantly decreased in group WS as compared with negative and control transfection groups (P 0.05). These results demonstrate that WSLP not only efficiently delivers NR1 siRNA targeting NR1 in vivo and inhibits the expression of NR1, but also reduces neuropathic pain in rats.

摘要： BACKGROUND: Isoleucine-lysine-valine-alanine-valine has good biological activity, and under certain conditions, it can self-assemble into isoleucine-lysine-valine-alanine-valine nanofiber hydrogel scaffold which is a natural biomimetic material for the spinal cord matrix. OBJECTIVE: To observe the effects of self-assembled isoleucine-lysine-valine-alanine-valine nanofiber gel on proliferation and differentiation of bone marrow derived neural stem cells in vitro. METHODS: Passage 2 bone marrow derived neural stem cells were co-cultured with isoleucine-lysine-valine-alanine-valine as experimental group, neural stem cells cultured alone counted as control group, and isoleucine-lysine-valine-alanine-valine was set as blank control group. Cel proliferation rate and differentiation proportion of neural stem cells into neurons were measured at 1, 3, 5, 7, 10, 14 days after culture using Cel Counting Kit-8 and flow cytometry, respectively. 3-(4,5-Dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide assay was used for detecting cytotoxicity of passage 2 bone marrow derived neural stem cells from new born Sprague-Dawley rats. RESULTS AND CONCLUSION: Cel proliferation rate and differentiation proportion of neural stem cells into neurons were significantly higher in the experimental group than in the control groups at each time (P < 0.05). Cel proliferation in the experimental and control groups peaked at day 7. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay detected no cytotoxicity of the isoleucine-lysine-valine-alanine-valine. Taken together, isoleucine-lysine-valine-alanine-valine nanofiber gel has a better biological activity, and can increase the differentiation proportion of neural stem cells into neurons.%　　背景：异亮氨酸-赖氨酸-缬氨酸-丙氨酸-缬氨酸具有良好的生物活性，在特定条件下可自组装成含IKVAV 纳米纤维凝胶支架，是一种天然的脊髓基质仿生材料。目的：进一步观察体外自组装异亮氨酸-赖氨酸-缬氨酸-丙氨酸-缬氨酸纳米纤维凝胶对骨髓源性神经干细胞增殖及向神经元分化的影响。方法：取第2代新生 SD 大鼠骨髓源性神经干细胞与自组装异亮氨酸-赖氨酸-缬氨酸-丙氨酸-缬氨酸纳米纤维凝胶共培养作为实验组，设置神经干细胞单独培养为对照组、单独自组装异亮氨酸-赖氨酸-缬氨酸-丙氨酸-缬氨酸纳米纤维凝胶为空白对照组，CCK-8法及流式细胞仪检测培养1，3，5，7，10，14 d 的细胞增殖与神经干细胞向神经元分化的比例；MTT 法检测自组装异亮氨酸-赖氨酸-缬氨酸-丙氨酸-缬氨酸纳米纤维凝胶对第2代新生 SD 大鼠骨髓源性神经干细胞的毒性。结果与结论：实验组不同时间点细胞增殖率及向神经元分化的细胞比例均高于对照组(P <0.05)，两组细胞增殖均于第7天达峰值。MTT 法检测结果显示自组装异亮氨酸-赖氨酸-缬氨酸-丙氨酸-缬氨酸纳米纤维凝胶无细胞毒性。表明异亮氨酸-赖氨酸-缬氨酸-丙氨酸-缬氨酸纳米纤维凝胶有较好的生物活性，可促进神经干细胞的增殖，提高神经干细胞向神经元分化的比例。

METHODS: (1) 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay: the cel proliferation of 293T cells incubated with acetylated polyamidoamine under 0, 0.125, 0.25, 0.5, 1, 2, 4 μmol/L concentrations was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. (2) Cel morphology: the cel morphology of 293T cells incubated with 4 μmol/L acetylated polyamidoamine was observed by inverted fluorescence microscope. (3) Cel cycle: the cel cycle of 293T cells incubated with acetylatedpolyamidoamine under 0, 5, 10, 15, 20 mg/L concentrations was detected by flow cytometry. RESULTS AND CONCLUSION: Polyamidoamine had cytotoxicity to 293T cells. The cel viability at 4 μmol/L concentration after 48 hours incubation was only 52%, and the acetylation could significantly decrease the cytotoxicity of polyamidoamine (P < 0.01). 293T cells incubated with polyamidoamine shrank and had bad stretching, while 293T cells incubated with acetylated polyamidoamine had good stretching. Acetylated polyamidoamine had no significant effect on the cel cycle, but polyamidoamine at 20 mg/L could block the cel cycle at S stage. Al the results show that acetylation can decrease the cytotoxicity of polyamidoamine.
