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.

OBJECTIVETo investigate the influence of the rate of morphologically normal sperm (MNS) on the clinical outcomes of conventional in vitro fertilization (IVF) in patients with one retrieved oocyte.

METHODSFrom January 2013 to January 2015, a total of 256 couples with one retrieved oocyte underwent conventional IVF in our center. According to the rate of MNS, the patients were divided into two groups: MNS < 4% (134 cycles) and MNS ≥ 4% (122 cycles). We compared the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo between the two groups. A total of 75 fresh embryo transfer cycles were performed, 43 in the MNS < 4% group and the other 32 in the MNS ≥ 4% group. We also compared the rates of implantation, clinical pregnancy and abortion between the two groups.

RESULTSThere were no statistically significant differences between the two groups in the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo (P > 0.05). The rates of implantation, clinical pregnancy and abortion exhibited no remarkable differences either in the fresh embryo transfer cycles between the two groups (P > 0.05).

CONCLUSIONThe rate of MNS does not affect the clinical outcomes of conventional IVF in patients with one retrieved oocyte.

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.
