On the basis that Panax Tonifying Soup Mix can effectively improve and postpone cytoarchitecture impairment in hepatic and brain tissues in subacute senile mice, in order to approach the dependablity between postponing anaplasia of senile tissue cells and the ability of cleaning oxygen free radicals, lipid peroxidatic conditions, degree of cell injury of the recipe-medicine, serum SOD activity and MDA content were selected as quantitative indexes for objectively evaluating the antioxidation of this recipe-medicine.

在明确人参养荣汤有效改善、延缓D-半乳糖所致亚急性衰老鼠肝、脑组织与细胞结构损伤的基础上，为探讨该方药延缓衰老组织细胞退行性改变与清除氧自由基能力、脂质过氧化状态，细胞损伤程度的相关性，选择血清SOD活性、MDA含量作为定量指标，旨在对该方药抗氧化作用给予客观地评价。

The reasons of RA focus on disbalance of immunity net, the effect of so many cytokines and MMPs , and the tumor-like proliferation of fibroblast-like synovicytes in joints, though the cause of developing disease is unknow.

RA的发病过程中，免疫网络失衡，加上成纤维样滑膜细胞(fibroblast-like synoviocytes，FLS)的类肿瘤样生长及所分泌的大量促炎性细胞因子、趋化因子和金属蛋白酶，是导致关节内炎性细胞聚集，滑膜细胞增生和向周围组织侵蚀及基质降解和破坏的主要因素。

By means of stereotaxis instrument, 1×105 BMSCs (2 μL) of passage 3 stained with Hochest33324 for 24 hours were transplanted into the left hippocampus at 24 hours, 72 hours and 7 day after induction of HIBD in the corresponding groups.

在脑立体定位仪下，24 h，72 h，7 d细胞移植组分别于造模后对应时间点，将体外培养3~5代且经Hochest33324标记24 h的鼠骨髓基质细胞2 μL脑内移植于左侧海马，约105个细胞。

The process of osteoarthritis mesochondrium degradation is possibly attributed to the synergistical consequence of MMPs and other factors. Pilose antler peptide can promote the proliferation of OA chondrocytes of rabbits ,inhibit the overexpression of MMPs of OA chondrocytes.It can possibly play a effective role in the treatment of OA.

结论骨性关节炎软骨细胞在骨性关节炎发病过程中，软骨细胞正常分化及增殖发生改变；骨性关节炎软骨基质降解过程可能是金属蛋白酶与其它因子协同作用的结果；鹿茸多肽可促进骨性关节炎软骨细胞增殖，并可抑制骨性关节炎软骨细胞中金属蛋白酶的过度表达，可能对治疗骨性关节炎有较好的作用。

Cytology revealed 3-dimensional groups of ductal cells in a background of myoepithelial cells and stromal cells, consistent with a fibroadenoma.

对该肿块进行细针抽吸活检，细胞学显示以肌上皮细胞和基质细胞为背景的三维导管细胞结构，与纤维腺瘤结构一致。

These nonmalignant cells, such as stromal fibroblasts and bone marrow-derived cells, have been shown to be capable of promoting tumor growth and metastasis.

这些非恶性细胞如基质成纤维细胞和骨髓源性细胞已被证明能够促进肿瘤的生长和转移。

The toxicity and the osteogenous ability on the surface of PCHA: Cytotoxicity tests demonstrated that PCHA has excellent biocompatibility, and cells grow normally on the surface of PCHA.

CHA毒性检测和表面细胞活性的观察：PCHA浸出液与骨髓基质细胞共培养，MTT检测细胞生长曲线与空白对照组无差异，表明材料无毒性。

The experimental group corneas were preserved by organ culture for 4 weeks, the corneal thickness was measured with ultrasonic corneal pachymeter. Then every corneas were divided into half -chip, there are 48 half-chip total. It was divided into 4 groups, there are 12 half-chip in every groups. The corneal endothelial cell density of 12 half-chip were counted through Alizarin Red-Trypan blue staining; 12 half-clip corneas were fixed with 4% neutral formalin solution, HE staining was performed, the expression of AQP-1 in corneal stroma and corneal endothelial cell were detected through immunohistochemical staining; Na~+-K~+-ATPase activities in 12 half-clip corneas were examined with Na~+-K~+-ATPase kit; the expression of AQP-1 mRNA were detected through real-time fluorescent quantitation PCR.

实验组经器官培养保存4周后以角膜测厚仪测量角膜厚度，然后每个角膜被分成两半，共48个半片角膜，再分成4组，每组12个半片。12个半片用茜素红-台盼蓝染色染色行角膜内皮细胞计数；12个半片角膜用4%中性福尔马林溶液固定行HE染色、应用免疫组化染色检测AQP-1在角膜基质和内皮细胞表达的改变；12个半片角膜用Na~+-K~+-ATP酶试剂盒测量角膜内皮细胞Na~+-K~+-ATP酶活性；12个半片角膜用实时荧光定量PCR检测AQP-1mRNA表达改变。

SPARC (secreted protein, acidic and rich in cysteine) is a multifunctional glycoprotein, which influences many important physiological and pathological processes, such as modulating cellular interaction with the extracellular matrix, abrogating cell focal adhesions, inhibiting cellular proli-feration, and regulating the activity of growth factors.

SPARC (secreted protein， acidic and rich in cysteine)即富含半胱氨酸的酸性蛋白，为一种多功能糖蛋白，在各种生理与病理过程中发挥作用，如调节细胞与细胞外基质(extracellular matrix， ECM)相互作用、溶解黏着斑完成抗黏附反应；抑制细胞增殖及调节生长因子活性等。

Results SDF-1/CXCR4 was present in the basal epithelial cells of normal conjunctiva. Of 20 pterygia cases, 17 expressed SDF-1/CXCR4 in the full thickness of the epithelium and CXCR4 was also found in the inflamed cells and vascular endothelial cells in the tissues; 3 primary pterygium cases showed the same staining pattern as that in normal conjunctiva.

结果 在正常结膜组织中SDF-1/CXCR4仅表达于基底部上皮细胞；胬肉组织中有17例，全层上皮细胞均有SDF-1/CXCR4的表达，胬肉基质层中浸润的炎性细胞、血管内皮细胞均有CXCR4的蛋白表达；3例初发性翼状胬肉表达方式与正常结膜相似。
