BACKGROUND: Non-invasive vascular ultrasound is used to assess in tima-media thickness (IMT) and atheromatous plaque, of which the result is better correlated to that of pathological examination. OBJECTIVE: Non-invasive vascular ultrasound was used to assess the hemodynamical changes of external and internal carotid in hypertensive elders, so as to investigate the relationship between pulse pressures, left ventricular mass index (LVMI), vascular resistance index (VRI) and shearing ratio. DESIGN: Randomized, controlled, correlative analyzedstudy. SETTING: Ultrasound Department of Affiliated Hospital of Jiangshu University. PARTICIPANTS: Totally 54 hypertensive elders, including 33 males and 21 females, were recruited from the Ultrasound Department of Affiliated Hospital of Jiangshu University, from September 30th 2000 to March 30th 2002. Meanwhile 26 normotensive elders (systolic pressure ＜ 130 mm Hg and/or diastolic pressure ＜ 85 mm Hg), including 16 males and 10 females, were selected as controls, METHODS: Color duplex blood flow imaging technique was used to assess the left ventricular end-diastolic diameter (LVEDD) and the interventricular septum thickness (IVST), so as to calculate the LVMI. The insiddiameter of bilateral common carotid artery (CCA) and internal carotid,IMT, the systolic peak flow velocity and resistance index were measured in order to calculate the vascular shearing ratio and atheromatous plaque index,moreover arterial pressure, LVMI, as well as resistance index and shearing ratio were subjected to linear correlative analysis,of which the results were compared with that of control group. MAIN OUTCOME MEASURES: ① Pulse pressure, LVMI and atheromatous plaque index of CCA. ② The inside diameter of bilateral CCA and internal carotid, IMT and the systolic peak flow velocity and resistance index were measured in order to calculate the atheromatous plaque index and maximum vascular shearing ratio. RESULTS: According to the experimental objective,data of all 80 cases were analyzed without loss. ① The pulse pressure and LVMI, the incidence of atheromatous plaque and plaque index of CCA in hypertensive elder group were obviously higher than that of control group [(64.36±7.44) mm Hg,(45.78±8.72) mm Hg; (131.47±18.73) g/m2, (83.28±12.34) g/m2; 5.62 ±1.78,3.44±1.10; 66.7％, 23.1％, (x2=13.37, t=5.730-13.234, P ＜ 0.01)]. ② The inside diameter of bilateral CCA and internal carotid, IMT and resistance index in hypertensive elders were significantly higher than that of control group [CCA: (8.96±1.20) mm, (8.08±0.96) mm; (1.28±0.88) mm, (0.91±0.17) mm;0.75±0.05, 0.69±0.06; ICA: (6.82±1.12) mm, (5.72±0.92) mm; (1.06±0.17) mm,(0.76±0.15) mm; 0.70±0.07, 0.64±0.06, t=2.872-10.850, P ＜ 0.01], but the systolic peak flow velocity and shearing ratio were markedly lower than that of control group [CCA: (47.44±12.85) cm/s, (60.20±14.32) cm/s;(225.78 ±95.76)/s, (300.26 ±110.42)/s. ICA: (41.22 ±10.18) cm/s,(48.64±11.58) cm/s; (268.54±112.56)/s, (324.52±121.42)/s, t=2.872-10.850, P ＜ 0.01]. ③ The pulse pressure, LVMI, the resistance index of CCA and ICA and shearing ratio were linearly correlated (r=0.30-0.36, P ＜ 0.05). CONCLUSION: Pulse pressure and LVMI were found increased in hypertensive elders, together with carotid vessels dilated, IMT and resistance index increased, as well as shearing ratio decreased, atheromatous plaque formed, vascular stiffness increased, which resulted in consequently decrease of vascular compliance.

Objective To explore the clinic value and efficacy of color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation for secondary hyperparathyroidism. Methods Fifty-six cases of secondary hyperparathyroidism who came from nephrology department of Beijing Friendship Hospital in the period of September 2012 to September 2013 were treated by color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation. One hundred and thirty-eight glands underwent this treatment and were evaluated by contrast enhanced ultrasound before, during and after operation. The levels of serum parathyroid hormone (PTH) were measured before and at 1 week, 1 month, 6 months and 1 year after treatment. Results The whole 56 cases achieved 1 month follow-up and 34 cases and 12 cases achieved 6 months and 1 year follow-up, respectively. Two special cases had been excluded. The PTH levels of 54 cases were signiifcantly different between after and before treatment [(369.5±183.4) ng/L vs (1321.6±471.4) ng/L, t=10.727, P=0.000]. The PTH levels continued to fall at the ifrst week after treatment, but there was no statistical signiifcance between the ifrst week and the ifrst day after treatment [(324.6±172.8) ng/L vs (369.5±183.4) ng/L], while there was signiifcantly different between the ifrst week after treatment and before treatment [(324.6±172.8) ng/L vs (1321.6±471.4) ng/L, t=9.364, P=0.000]. The PTH levels increased from (324.6±172.8) ng/L to (332.5±164.9) ng/L at 1 week and 1 month after ablation, while there was no signiifcant difference.But there is signiifcantly different between 1 month after treatment and before treatment (t=11.348, P=0.000). The PTH level at 6 months after treatment [(205.2±136.3) ng/L] and 1 year after treatment [(177.1±171.5) ng/L] had signiifcant difference compared with the value before treatment (t=8.737, P=0.000; t=7.655, P=0.017). Conclusion Color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation can be considered as a feasible and effective nonsurgical alternative treatment for secondary hyperparathyroidism patients.

Because of the population aging,the increase of the stroke patients and the need for rehabilitation,the treatment only in the rehabilitation department of the hospital is far from the satisfaction of people's demands of the service of rehabilitation.It is important to extend the community-based rehabilitation.Compared with the rehabilitation in hospitals,it is more economy,efficiency and convenience for stroke patients in community-based rehabilitation services,and further improve the rehabilitation effect of stroke patients.

BACKGROUND:Santoni put forward the cortical bone trajectory technology by changing the traditional pedicle screw placement for lumbar internal fixation in order to obtain better control of the screw and bone in 2009. OBJECTIVE:To analyze biomechanical stability of cortical bone trajectory system in the lumbar fusion. METHODS:Twenty fresh newborn calf L3/4, L5/6 motion segment specimens were obtained, and their ranges of motion were detected under different states, as normal controls. Subsequently, twenty samples were divided into cortical bone trajectory screw group and traditional pedicle screw group, which underwent cortical bone trajectory screw fixation combined with posterior lumbar fusion and traditional pedicle screw fixation combined with posterior lumbar fusion, respectively. Without destruction, ranges of motion were detected under different states in both groups. In the revision group, after the test in the traditional pedicle screw group, screw was withdrawn, and cortical bone trajectory screw was used to detect its range of motion under different states. RESULTS AND CONCLUSION:Ranges of motion at bending to the left and right, anteflexion, posterior extension and axial rotation were significantly lower in the cortical bone trajectory screw group and traditional pedicle screw group than in the normal control group (P<0.05). No significant difference in bending to the left and right, anteflexion, posterior extension and axial rotation was detected between the cortical bone trajectory screw and revision groups and traditional pedicle screw group (P>0.05). These results confirmed that cortical bone trajectory technology combined with posterior lumbar fusion can obtain identical stability as the traditional pedicle screw fixation combined with posterior lumbar fusion. Simultaneously, it is a new choice for revision after traditional pedicle screw fixation.

OBJECTIVETo explore methods of treating middle and distal tibia nonunion with the treatment of advanced bone graft combined with locking compression plate.

METHODSFrom January 2011 to December 2012, 12 patients with middle and distal tibia nonunion were treated with advanced bone graft combined with locking compression plate. Among patients, there were 8 males and 4 females aged from 20 to 69 with an average of 47 years old. The time from first injuries to bone nonunion was from 9 months to 5 years, avergaed 19 months. Four cases were treated with external fixation, 6 cases were treated with plate fixation, 2 cases of 12 patients occurred broken of plate and nail. Eleven patients were non-infective bone nonunion and 1 patient was infective bone nonunion. Preoperative X-ray and CT showed all patients had sequestration and formation of ossified bone with different degrees. Operative time, blood loss, wound healing were observed, fracture healing time was evaluated by postoperative X-ray. Johner-Wruhs scoring standards was used to evaluate ankle joint function after operation at 10 months.

RESULTSOperative time ranged from 90 to 185 min with an average of (125.00±20.15) min; blood loss ranged from 225 to 750 ml with an average of (415.00±120.00) ml. All patients were followed up from 10 months to 2.5 years with an average of 1.5 years. Postoperative X-ray showed bone union was formed around fracture after operation at 4 months in all patients, 3 cases obtained bone healing within 6 months after operation, 9 cases obtained from 8 to 12 months. No infection, injury of nerve and vessles, and broken of plate and nail were ocurred. According to Johner-Wruhs scoring at 10 months after operation, 10 cases obtained excellent results, 1 good and 1 moderate.

CONCLUSIONAdvanced bone graft combined with locking compression plate, which can build fracture multi-point supporting based on full compression of bone nonunion to get effective fixation, is an effective method in treating middle and distal tibia nonunion.
