BACKGROUND:It has been reported that treatment with granulocyte-colony stimulating factor (G-CSF) increases the abundance of circulating CD34+ cells in rats. Data from the study, more important, suggested that mobilized by G-CSF may enhance rapid reendothelization and reduce neointimal formation after vascular injury.OBJECTIVE: To evaluate whether BM-derived CD34+ cells could enhance rapid reendothelization and reduce neointimal formation after balloon-injured carotid artery in an intact rat model.DESIGN: Randomized control animal study.SETTING: Nanjing First Hospital Affiliated to Nanjing Medical University.MATERIALS: The experiment was carried out in Nanjing First Hospital from December 2005 to April 2006. A total of 40 male Sprague-Dawley rats, weighing 200-250 g and of SPF grade, were purchased from National Rodent Laboratory Animal Resources, Shanghai Branch. The recombinant human G-CSF was purchased from Qilu Pharmaceutical. The 2F Fogarty arterial embolectomy catheters were purchased from Edwards Lifesciences. Anti-human CD34 and anti-human CD45 were purchased from Multi Sciences.METHODS: SD rats were divided randomly into treated group (n =20) and control group (n =20). Subcutaneous injection of recombinant human G-CSF (100 μg/kg/day) once daily for 8 days for treated group. Control group as treated with subcutaneous injection of saline. Five days after initiation of G-CSF treatment or saline, the rats were anesthetized by intraperitoneal injection with ketamine. The left common carotid artery was exposed through a midline incision of the ventral side of the neck. A 2F Fogarty arterial embolectomy catheter was inserted through the external carotid artery,inflated with 200 μL air, and passed 3 times along the length of the segment, which was defined proximally by the carotid bifurcation and distally by the edge of the omohyoid muscle. After removal of the catheter, the proximal ligature of the external carotid artery was tied off. ① An average of 1 mL venous blood per rat was collected for enumeration of the white blood wells (WBCs) and CD34+ cells before and 5 days after initiating G-CSF or saline treatment. ② Ten rats in each group were killed with overdose ketamine at 14 and 28 days after balloon injury and left common carotid arteries were harvested. The luminal surface of carotid arteries (n =5, each group) was exposed to calculate the reendothelialized area, which was manually traced with software (Image ProPlus). Reendothelialized area = non-stained with Evans blue area/the total area of balloon-injuried. The cross sections of carotid arteries (n =5, each group) were stained with hematoxylin and eosin (HE) and calculated intima-to-media area ratio (I/M) with software (Image ProPlus) to assess the extent of neointimal thickening. ③ To evaluate the extent of reendothelialization of arteries injury, sections were stained with CD31 and vWF by immunohistochemistry analysis.MAIN OUTCOME MEASURES: ① The number of WBCs and CD34+ cells; ② the extent of reendothelialization of arteries injury; ③ the extent of neointimal hyperplasia (I/M); ④ CD31 + and vWF+ endothelial cells.RESULTS: A total of 40 rats were involved in the final analysis. ① The number of WBCs and CD34+ cells: After 5 days of treatment, the number of WBCs in the treated rats increased more than 2.7-fold compared with control group [(27.60±2.45) ×109 L-1, (10.11±1.81) ×109 L-1, P ＜ 0.01], CD34+ cells increased more than 12.2-fold compared with control group (38.31×107 L-1, 3.14×107 L-1, P ＜ 0.01). ② The extent of reendothelialization: At 14 and 28 days after balloon injury,carotid artery of reendothelialization in the treated group were (68.3±8.3)％ and (97.6±4.1)％, superior than the control group (33.8±6.3)％ and (76.1±5.2)％ (P ＜ 0.01). ③ The extent of neointimal hyperplasia: At 14 and 28 days after balloon injury, the neointima-media (I/M) ratios in the treated rats were 0.39±0.11 and 0.45±0.09, less than the control group 0.87±0.15,1.26±0.16 (P ＜ 0.01). A highly significant inhibition of neointimal hyperplasia was observed in the treated group. ④ CD31+ and vWF+ endothelial cells: At 28 days after injury, sections from G-CSF treated group showed almost complete and continuous monolayer of CD31 and vWF positive cells.In contrast, a patchy and interrupted CD31 and vWF positive cells were found lining the lumen of control group.CONCLUSION:Treatment with G-CSF significantly increases the number of CD34+ cells and accelerates the rate of reendothelialization of injured vessels, leading to marked inhibition of neointimal formation after vascular injury in rats.

ObjectiveTo explore the relationship between the mRNA and protein expressions of NIX and the pulmonary alveolus apoptosis following severe acute lung injury (ALI).Methods Rat models of severe collision injury on the chest were built.The mRNA and protein expressions of NIX in the alveolar cells at 6,12,24,48,72 and 96 hours after injury were detected using immunohistochemistry,immunoblotting and RT-PCR.Meanwhile,apoptosis of the alveolar cells was checked at different time points with Tunel assay.ResultsThe protein expression of NIX in the alveolar cells was observed both in experimental and control groups,which increased at 6 h post injury,peaked at 48 h and then declined till approaching the pre-injury level at 96 h.In the meantime,NIX showed a high expression both in the vascular endothelial cells (VECs) and the renal interstitial fibroblasts.The apoptosis of alveolar cells mainly presented in bronchi,blood vessel endothelium (BVE) and alveolar epithelium at 24 h post injury.The post-injury apoptosis rate of the alveolar cells was significantly higher than the pre-injury rate ( P ＜ 0.01 ),which reached the peak at 72 h and then decreased gradually.The changes of NIX protein in lung tissue showed a positive correlation with the apoptosis rate of alveolar cells after injury (r =0.303,P ＜ 0.01 ).ConclusionsThe up-regulated expression of NIX takes part in the pathophysiological process of apoptosis of the alveolar cells and shows consistency with the apoptosis rate change of the alveolar cells,as may be the molecular basis for apoptosis of the alveolar cells after ALI.

BACKGROUND: Treatment for acetabular fracture becomes a hot point in orthopaedic trauma, but ignorance of rehabilitative treatment that effect therapeutic efficacy is to be seen repeatedly. Normative rehabilitation therapy is one indispensable procedure of acetabular fracture treatment.OBJECTIVE: To investigate the effect of early rehabilitation on the hip joint function in patients with comminuted posterior wall fractures of the acetabulum after internal fixation.METHODS: Forty patients of comminuted posterior wall fractures of the acetabulum at the Department of Orthopedics, Third Hospital of Hebei Medical University, were selected, including 36 males and 4 females, aged 23-61 years, mean aged 35.3 years. All patients were randomly divided into rehabilitation and control group, with 20 patients in each group. All the patients were fixed with reconstruction plate, the patients in the rehabilitation group received early standard rehabilitation exercises intervention and those in control group received usual care. The clinical result was evaluated with the scores of Merle d'Aubigne and Postel.RESULTS AND CONCLUSION: The scores of Merle d'Aubigne and Postel of the rehabilitation group were (13.10±2.05),(14.50±1.32), and (15.80±1.36) points at months 3, 6, and 12 after operation, which were greater than those of the control group (11.20±2.80), (13.00±2.10), and (14.25±1.74) points, respectively (P<0.05). The early rehabilitation exercises may improve the hip joint function for patients of the comminuted posterior wall fractures of the acetabulum after surgery.
