BACKGROUND: The reaction of osteoblasts is important role in the reconstruction of osteocytes, and the mechanism of bone remodeling can be known from the cytological level through analyzing the mechanical reaction of osteoblasts under different loading.OBJECTIVE: To analyze the effects of low frequency vibration on the proliferation and differentiation as well as the matrix excretion of cultured human osteoblasts.DESIGN: A comparative observation.SETTING: Department of Orthopaedics, Nanfang Hospital of Southern Medical University.MATERIALS: The experiment was carried out in the laboratory of Nanfang Hospital from January to December in 2002. Human osteoblasts were isolated from the iliac cancellous bone of adults.METHODS: The osteoblasts were cultured for 48 hours, and then treated with low frequency vibration of 0.1, 0.2, 0.5, 2 and 5 Hz. The proliferation of the osteoblasts was detected with flow cytometry, and the activity of alkaline phosphatase (ALP) and content of osteocalcin were assayed by spectrophotometric methods and radioimmunoassay respectively.MAIN OUTCOME MEASURES: ① Effects of low frequency vibration on the ALP activity and osteocalcin excretion of osteoblasts; ② Effects of low frequency vibration on the proliferation of osteoblasts detected with flow cytometry.RESULTS: ① 0.2 and 0.5 Hz vibrations could markedly increase the ALP activity of osteoblast (P ＜ 0.01), but that of 5 Hz obviously decreased the ALP activity (P ＜ 0.01). 0.1 and 2 Hz vibrations had no obvious effects on the ALP activity of osteoblasts. ② 0.2 and 0.5 Hz vibration could significantly increase number of osteoblasts at S phase from 10.4% to 12.45% and 16.12%, and the proliferative index increased from 20.14% to 26.21% and 28.75%; 0.1 and 2 Hz vibration has not obvious effects in osteoblast proliferation index; 5 Hz vibration obviously decreased the proliferative index value to 13.22% (P ＜ 0.05). 0.1 and 2 Hz vibrations had no obvious effects on the proliferative index of osteoblasts (P ＞ 0.05). ③ 0.2 and 0.5 Hz vibrations could obviously increase the amount of osteocalcin excretion to 1.87 μg/L and 2.47 μg/L(P ＜ 0.05), but 2 and 5 Hz vibrations decrease the amount of osteocalcin excretion (P ＜ 0.05), and that of 0.1 Hz had no obvious effect on amount of osteocalcin excretion (P ＞ 0.05).CONCLUSION: Low frequency vibrations of 0.2-0.5 Hz could accelerate the proliferation and differentiation as well as the excretions of active materials of osteoblasts, and it plays an instructive role for low frequency vibration to treat fracture.

BACKGROUND: Using low-intensity pulsed ultrasound (LIPU) to promote the repair of articular cartilage injury is very common,and we also have more options to choose the cytoskeleton, but the application conditions of LIPU and the appropriate cytoskeleton have not reached any consensus yet.OBJECTIVE: To investigate the feasibility of establishing tissue-engineered cartilage by cell-free allograft demineralized bone matrix (CFDBM) co-cultured with rabbit cartilage cells and bone marrow mesenchymal stem cells (BMSCs) in vitro, and to investigate the effect of LIPU on the cells in CFDBM.DESIGN, TIME AND SETTING: Multiple sample observation was performed at the Institute of Biomedical Engineering, Second Military Medical University of Chinese PLAfrom May to August 2009.MATERIALS: The CFDBM was prepared as modified Urist's method; the cartilage cells were obtained using mechanical disintegration and enzyme digestion; the BMSCs were separated using whole bone marrow rinsing method, purified, and amplified layer by layer.METHODS: As CFDBM With a composite of different cellular components, and whether applying LIPU stimulation, the samples were divided into four groups: chondrocyte group, BMSCs group, compound group (CFDBM was compounded with chondrocytes,BMSCs, and chondrocytes/BMSCs, respectively, without LIPU stimulation), and LIPU group (CFDBM was compounded with chondrocytes/BMSCs, and then the samples were stimulated with LIPU on the second day, 1.0 MHz frequency, 10 mW/cm~2 transient spatial intension, 20 min/d).MAIN OUTCOME MEASURES: ① the 2~(nd)-generation of cartilage cells and BMSCs were examined by immunohistochemical method; ② The CFDBM prepared as modified Urist's method was examined as HE staining; ③ The samples of four groups were examined by collagen II immunohistochemical staining on the 21~(st) day.RESULTS: ① The collagen II immunohistochemical staining of the second generation of the articular cartilage cells showed that the morphostructure was polygon, star or round, and pseudopodia extended, and the cells were rich in cytoplasm; the cytoplasm was brownish yellow, and the cell nuclear was round. ② The result of immunohistochemical staining of BMSCs showed that,CD34 was negative, CD44 and CD105 were positive. ③ In the center of CFDBM prepared as modified Urist's method, there was no obvious cell-like structure and the gap size was uniform. ④ On the 21~(st) day after combining CFDBM with cells, collagen II immunohistochemical staining demonstrated that BMSCs group was negative, chondrocyte group was weak positive, compoundgroup was positive, and the LIPU group was strongly positive.CONCLUSION: ① Biological property of the 1~(st)-3~(rd)-passage chondrocytes and BMSCs was similar to primary-cultured cells. ②Both chondrocytes and BMSCs had a highly proliferative ability in CFDBM. ③ 10 mW/cm~2 LIPU could not affect activity of BMSCs but could promote differentiation Into articular cartilage cells, and it also could not promote celt proliferation.

Objective To investigate the feasibility and safety of percutaneous interstitial implantation of ~(125)I seeds into the pancreas of pig under CT-guidance. Methods Twelve healthy pigs were equally divided into 6 groups.~(125)I seed implantation into the pancreatic tail under CT-guidance was performed in pigs of study groups (group A-E), while ghost seeds that contained no radioactive materials were used in the control group (group F). Imaging examination and laboratory tests, including serum amylase, hepatic and renal functions, were conducted before and 1, 7, 15, 21, 30, 60 days after the procedure. Every two pigs (group A-E) were sacrificed each time at 15, 30, 45, 60, and 75 days after treatment, and specimens of pancreas, duodenum, liver, kidney, etc. were collected and sent for pathologic examination. Results The ~(125)I seeds were successfully implanted in all pigs. During the follow-up period, no severe complications occurred. Imaging and pathologic studies demonstrated that in study groups necrosis of pancreatic tissue appeared around the implanted ~(125)I seeds in 15 days, the necrosis area increased significantly in 45 and 60 days, and in 75 days the necrosis size remained quite the same as seen in 60 days. No necrosis was found in the control group (group F) 60 days after treatment. No serious complications, such as effusions, hemorrhage or necrosis of the adjacent duodenum, stomach, liver or kidney, occurred 75 days after the treatment. Conclusion Percutaneous interstitial implantation of ~(125)I seeds into the pig's pancreas under CT-guidance is safe and feasible.
