Objective To evaluate the image deformation and measurement error of rotational DSA by model experiment. Methods Five steel balls (diameter: 20 mm) were placed in a horizontal space of 30 mm, the middle of which was as the isocenter for rotational DSA acquisition. Another 5 steel balls (diameter: 10 mm) were placed in a vertical space of 30 mm with the same alignment for rotational DSA acquisition. The screen was divided into five regions and the morphological changes of the ball image were observed at each rotation angle. The experimental images of the left anterior oblique ball images at 20°, 40°and 60° among each two groups were selected and measured by automatic isocenter calibration and sphere calibration respectively, and compared with the actual diameters of balls to calculate the image magnification. Results Except the center one, other balls were of deformation at different rotation angles due to the distance to the detector leading to enlargement and reduction. With automatic isocenter calibration, only the diameter of the center ball corresponded with the actual one, the distance away from the center or the rotation angle was inversely proportional to measurement error (maximum magnification 12.42%).With sphere calibration, the measurement results in various regions at different rotation angle were basically the same, with smaller measurement error (maximum magnification 3.41%). Conclusion Placing the organ of interest in the center area can reduce image distortion in rotational DSA imaging. Selecting reasonable measuring technology according to the lesion location is helpful to control measurement errors.

Objective To explore the effect of low intensity pulsed ultrasound stimulation (LI-PUS) on the maturation of regenerate bone in a rabbit limb lengthening model. Methods Sixty skeletal mature female New Zealand white rabbits were randomly divided into an LIPUS treatment group and a control group. All rabbits were underwent mid-diaphyseal tibial osteotomy and immobilized in an Orthofix M103 Mini lengther. Gradual distraction at 0. 5 mm every 12 h for 10 d was performed at day 7 postoperatively. A 4-week course of LIPUS treatment group was applied over the distraction site for 20 min daily starting immediately after the completion of the distraction only for the treatment group. Rabbits were euthanized and the mid-diaphyseal tibia was harvested for evaluation at 4, 8, and 12 wk after the completion of the bone lengthening protocol. Radiographic analysis was performed to study the formation of bone callus using the ImageJ software at 12 wk after the completion of the bone lengthening protocol. Bone mineral density (BMD) of regenerate bone was measured by Dual energy X-ray absorptiometry (DEXA) . Torsional testing to failure was performed on the tibia specimens at 8 and 12 wk after the completion of the bone lengthening protocol. Results Radio-graphic measurement showed higher relative gray scale of bone callus in the LIPUS group than that in the control group at 12 wk (P ＜ 0. 05) . BMD in the LIPUS group was significantly higher than that in control group at 8 and 12 wk (P ＜ 0. 05). Biomechanical testing showed that the ultimate torque, ultimate torsional stiffness, and energy absorption at failure of regenerated bone at 8 and 12 wk in the LIPUS treatment group were better than those in the control group (P ＜ 0. 05) Conclusion LIPUS as a biophysical stimulation may accelerate the formation and maturation of regenerate bone in rabbit tibia lengthening model.

Many somatic cell typos were obtained by in vitro differentiation or teratoma formation of human embryonic stem ceLls (hESCs). However, it is unclear whether specific cell types can be obtained from hESCs-derived teratoma. It was reported that many kinds of cells, including neural progetfitor/precursor cells (NPCs) and mesenchymal stem cells (MSCs) were isolated efficiently from the teratoma of hESCs through in vitro selection. The teratoma-derived NPCs and MSCs showed specific characteristics of molecular markers similar to the primary NPCs and MSCs. Moreover, these teratoma-induced NPCs and MSCs can be further induced to differentiate into neurons, astrocytes, or adipose and bone cells, reflecting their inherent multi-potencies. Given that teratoma normally contains a mixture of ectoderm, mesodenn, and endoderm lineage cells at different differentiation stage, it was suggested that hESCs-derived teratoma could be an alternative source to generate a variety of uncommitted progenitor cells or terminally differentiated somatic cells, which may be otherwise difficult to obtain through direct in vitro differentiation.

BACKGROUND: Experiments has demonstrated that low-intensity pulse ultrasound stimulations(LIPUS) can accelerate bone healing. However, Its affect mechanisms on maturation of regenerated bone remain unclear.OBJECTIVE: The hypothesis that LIPUS has positive effect on maturation of regenerate bone was put forward creatively, and wants to vedfy the hypothesis by compare the difference between LIPUS intervention and no intervention.METHODS: Thlrty-six adult, healthy, New Zealand White rabbits were randomly assigned to LIPUS treatment group and control.group, with 18 animals in each group.All animals were undergone mid-diaphyeaal tibia ostactomy and were immobilized in Orthofix M103 Mini lengtheners. After a eaven-day latency period, gradual distraction of 0.5 mm per twelve hours for 10 days to produce 10 mm distraction. A 4-weeks course of LIPUS treatment was applled over the distraction site for twenty minutes daily starting immediately after the completion of distraction. At weeks 4, 8, 12 after distraction, the bone healing was evaluated by X-ray film, and total mineralized areas were measured by Image J software. The newly formed bone In the lerigthening field was harvested and stained with haematoxylin-eosin, Masson's tdchroma end VG. Thearaas of newly formed bone were measured to calculate a percentage of the total callus area.RESULTS AND CONCLUSION: Thirty-six rabbits ware included in the final analysis, At week 4 after distraction, the maturation of newly formed bone in LIPUS treatment group appeared eadier than that in the control groups. The bona callus image presented in the marginal and center region of experimental defect, increased greatly and had higher density until filled of the lengthening fields. Many bone-like masses appeared in the newly formed tissues and the tissues surrounding the bone granules partially changed Into bone-like tissues, and the rate of callus production was increased (P ＜ 0.05). There was no significant difference between two groups at weeks 8 and 12 after distraction. Histological results showed that that new bone formation of the LIPUS group was earlier than the control group at weeks 4, 8, and 12 after distraction. The percentage of new bona on total callus area of the LIPUS group was greater than that of the control group at weak 4, but there was no obvious difference at weeks 8 and 12 after distraction. LIPUS accelerates new bone formation, increases the size of the distraction callus, exhibits highly effective in achieving maturation of bone in the animal modal with distraction osteogenesis.

Objective: To explore the value of real-time three-dimensional echocardiography (RT-3DE) combined with myocardial contrast echocardiography (MCE) in evaluating myocardial dysfunction in type 2 diabetes mellitus (T2DM) patients. Methods: Totally 58 T2DM patients were divided into group (T2DM isolated ) and group Ⅱ (T2DM associated with microvascular complications, each n=29). Group C included 32 normal individuals. The standard deviation (Tmsv16-SD, Tmsv12-SD, Tmsv6-SD) and the maximum time difference (Tmsv16-Dif, Tmsv12-Dif, Tmsv6-Dif) of the time to the minimum systolic volume of left ventricle were measured with RT-3DE. MCE was performed to obtain perfusion measurement of each segment of ventricular wall, including the acoustic intensity (A), microvascular flow velocity (β) and A•β. Results: There were statistically significant differences in all synchronize measurements except Tmsv6-Dif between group Ⅱ and group C (all P<0.05). Tmsv12-Dif, Tmsv12-SD, Tmsv12-Dif% and Tmsv12-SD% of group prolonged comparing with group C (all P<0.05). All the parameters of A, β and A•β showed a gradually decreasing trend in group C, group and group Ⅱ, while those in group Ⅱ were lower than group C (all P<0.05). The parameters of β and A•β in group Ⅱ were lower than those in group (both P<0.05). Compared with group C, the values of β and A•β in group decreased (both P<0.05). There was no significant difference of the same measurement in segments among three groups (all P>0.05). Conclusion: Left ventricular desynchrony can be observed in T2DM patients with or without microvascular complications. Myocardial perfusion reduce in T2DM patients presenting as diffuse damage, which aggravated with microvascular complications in other organs.

OBJECTIVETo study the predictive factors that are associated with intraoperative identification of the sentinel lymph node (SLN).

METHODSLymphatic mapping using blue dye was performed in 108 patients with stage I and II operable primary breast cancer. Subsequently the patients received operations of breast cancer including axillary dissection. Clinical and histological factors were assessed to determine those that were associated with intraoperative identification of the SLN.

RESULTSThe sentinel node was identified at the time of surgery in 84 patients (77.78%). Of the clinical factors assessed, age(y) < 50 (chi(2) = 7.447, P < 0.01), tumour in the upper quadrant (chi(2) = 6.330, P < 0.05), diagnosis by preoperative biopsy (chi(2) = 5.509, P < 0.05), successful mapping of the lymphatic duct (chi(2) = 13.125, P < 0.01) were significant in identifying the sentinel node at operation. No histological factor was associated with intraoperative identification of the sentinel node.

CONCLUSIONThere are the possibility of failure of SLN identification at sentinel lymph node biopsy. Our results suggest that the best predictor of intraoperative sentinel node identification is the visualization of the lymphatic duct on mapping by blue dye. Other factors such as age, tumour site as well as diagnostic method are also important in determining the success of the procedure.
