BACKGROUND:Percutaneous vertebroplasty is mainly used to treat senile osteoporotic compressive fractures,while for young patients,pedicle screw internal fixation is usually applied,but heavy trauma,nail broken,secondary surgery and other problems can be found occasionally.OBJECTIVE:To investigate the clinical efficacy of percutaneous vertebroplasty combined with granulated allogeneic bone grafting for thoracolumbar compressive fractures.METHODS:Twenty-one patients suffering thoracolumbar compressive fractures were recruited,and underwent percutaneous vertebroplasty combined with granulated allogeneic bone grafting.The Visual Analogue Scale scores,height ratio of fractured vertebrae and Cobb angle were detected before and after surgery.RESULTS AND CONCLUSION:(1) Compared with baseline,the Visual Analogue Scale scores were improved significantly at 1 day and 6 months postoperatively (P ＜ 0.05).(2) The height ratio of fractured vertebrae at 1 day and 6 months postoperatively was significantly higher than that before treatment (P ＜ 0.05).(3) The Cobb angle of fractured vertebrae at 1 day and 6 months postoperatively was significantly less than that before treatment (P ＜ 0.05).(4) The mean operation time was (52±12.3) minutes,and the mean blood loss was (11.5±1.5) mL.(5) These results suggest that percutaneous vertebroplasty combined with granulated allogeneic bone grafting can effectively restore the anterior fractured vertebral height,eliminate the cavity in the fractured vertebrae,renew the completeness and stabilization of the fractured vertebrae,which keep the spinal range of motion;therefore,it is a minimal invasive method in the treatment of thoracolumbar fractures.

Objective To investigate the value of radionuclide bone imaging in the diagnosis and localization of osteoporotic vertebral compressive fracture.Methods Percutaneous vertebroplasty was applied to 40 patients suffering from osteoporotic vertebral compressive fracture.Responsible vertebral bodys located according to the radionuclide bone imaging was involved as bone scan group,and responsible vertebral bodys located according to the physical examination,X-ray,CT and MRI as standard group.Then the Kappa test was carried out.Result In bone scan group,56 vertebrae were located by radionuclide bone imaging,and in standard group,58 vertebrae were located by X-ray,54 vertebrae by CT and 52 vertebrae by MRI.The Kappa value was 0.76,indicating essentially excellent agreement and statistical significance.Conclusion Radionuclide bone imaging was another good choice for the diagnosis of osteoporotic vertebral compressive fracture.Especially for cases with contraindication of MRI,it offers a reliable choice.

With the rapid development of medical imaging equipment, the higher requirement for the practice skills of the medical imaging professionals has been put forward. The traditional “CT and MR diagnostics” experimental teaching has some disadvantages, such as poor quality of images, imbalance of teaching resources, students' lack of practical skills training, no reflection of the practi-cal skills in the course examination and so on. They are not conducive to the cultivation of talents. Aimed to improve the experimental teaching quality of the course and students' practical skills, the reformative teaching method and means have been carried out, such as improving the laboratory facil-ities , composing experimental guidance , encouraging students to learn actively , strengthening the examination of practical skills, cultivating teachers in many different ways and so on. Through the survey, 92.9% of the students expressed satisfaction with the experimental course teaching reform. These measures will also be used in the teaching of all the sub courses of medical imaging diagnostics to promote the medical imaging professional training.

Objective To observe the influences on NO, NOS, ET of the Therapy of Tonifying the Kidney in patients with angina pectoris. Methods 50 patients with angina pectoris were treated by Chinese medicine of tonifying the kindey and the NO, NOS, ET, symptoms, ECG (ischemic ST-T changes), holter ECG, blood viscosity and blood fat were recorded. Results Obvious rise of NO, NOS and drop of ET.

Objective To observe the effect of the therapy of tonifying the kidney on plasma NO and ET in dog with myocardial ischemia. Methods 20 dogs of myocarclial ischemia were divided into the model group control group, isosorbide mononitrate group and the therapy of tonifying the kidney group by random. The NO and ET of serum were measured before and after treatment. Results The level of NO was higher and the level of ET was lower than that of the isosorbide mononitrate group. There was significant difference between the control group and the therapy of tonifying the kidney group (P

OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.

METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.

RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).

CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.

Objective: To observe the effect of the acupuncture plus medication on the expression of silent information regulator of transcription 1 (SIRT1) and transcription factor forkhead box protein O3a (FOXO3a) in the hippocampus, the malondialdehyde (MDA) content, and the superoxide dismutase (SOD) activity of rats with Alzheimer disease (AD), and to explore the possible mechanism of combining acupuncture and medication in improving AD-related neurological symptoms. Methods: Sixty male Sprague-Dawley rats were divided into a normal group, a model group, an electroacupuncture (EA) group, a drug group, and an acupuncture-medication combined group by the random number table method, with 12 rats in each group. The model was established by micro-injection of streptozotocin into the bilateral lateral ventricles. After successful modeling, rats in the EA group received EA at Zusanli (ST36) and Dazhui (GV14), those in the drug group received intragastric administration of resveratrol at a dose of 44 mg/(kg·bw), and those in the acupuncture- medication combined group received the combined intervention of EA and resveratrol. Rats in each group received intervention once a day for 4 consecutive weeks. Morris water maze was used to detect the rat behavioral changes. Nissl staining method was used to observe the cell morphology and changes in the number of rat hippocampal neurons. Western blotting and immunohistochemical staining methods were used to observe the expression changes of SIRT1 and FOXO3a. The thiobarbituric acid method was used to detect the MDA content. SOD activity was determined by the hydroxylamine method. Results: Compared with the normal group, the escape latency was significantly prolonged (P<0.05); the percentage of stay in the target quadrant was reduced (P<0.05), the hippocampal neuronal cells were shrunken, nucleoli were unclear, and cell number was reduced (P<0.05); the SIRT1 expression and SIRT1 positive cell number were decreased, while the FOXO3a expression and FOXO3a positive cell number were increased significantly (P<0.05); the MDA content was increased significantly, and the SOD activity was decreased significantly (P<0.05) in the model group. Compared with the model group, the escape latency was shortened (P<0.05); the percentage of stay in the target quadrant was increased (P<0.05); the shape and number of hippocampal neurons tended to be normal (P<0.05); the SIRT1 protein expression and the SIRT1 positive cell numbers were increased, the FOXO3a protein expression and the FOXO3a positive cell number were decreased (P<0.05); the MDA content was significantly decreased, and the SOD activity was significantly increased (P<0.05) in the EA group, the drug group, and the acupuncture-medication combined group. The changes in the acupuncture-medication combined group were more obvious (P<0.05). Conclusion: Both EA and resveratrol improve the learning and memory ability of AD rats by regulating the expression of SIRT1 and FOXO3a and improving the levels of MDA and SOD in the hippocampus and protect the hippocampal neurons, while the combined use of EA and medication is more effective than EA or resveratrol alone, suggesting that this combined treatment is more effective in AD treatment.

Objective To search for a procedure for correction of square face. Methods 68 patients with square face (aged from 21～40 years, with 65 females and 3 males) underwent osteetomy combined mandibular angle triangle resection with lateral cortex around the mandibular angle-splitting by intraoral approach. The mandible outer cortex was splited with bone chisel and mandible angle was resected by the high-speed pneumatic drill. The bulky masseter muscle and the enbonpoint buecal fat-pad were scissored. Results The application of high-speed pneumatic drill and bone chisel facilitated resection of the mandibular angle with lateral cortex splitting osteetomy. The operative effects were satisfactory in 56 patients during 3-24 months of follow-up. The bigonial distance was effectively re-duced, and facial shape became ellipse. The gross asymmetry and mandibular fracture were not conse-quences. The lateral contour of the mandibular angle was natural. Conclusion Ostectomy of mandible angle and lateral cortex of the mandible allows the reduction of the mandibular contour of the frontal view and the lateral contour of mandibular angle becomes soft, giving a more natural appearance. This new method is worthy to be applied widely because of the good result with effective reduction of the mandibular width.

Objective: To evaluate the effect of high-intensity interval somatosensory training combined with neuromuscular acupoint electrical stimulation on blood glucose and motor function among patients with type 2 diabetes mellitus (T2DM), so as to provide insights into prevention of daily life disability among T2DM patients. Methods: T2DM patients treated in Zhejiang Hospital during the period from January 2019 to October 2021 were enrolled and randomly assigned into four groups. Patients in the K group received Kinect somatosensory interaction technology-assisted high-intensity interval training, patients in the N group received neuromuscular acupoint electrical stimulation, and patients in the KN group received high-intensity interval somatosensory training combined with neuromuscular acupoint electrical stimulation, while patients in the C group were given no interventions. The 2 h postprandial plasma glucose and glycated haemoglobin (HbA1c) levels were measured prior to interventions and 4 and 12 weeks post-interventions, and seven physical fitness tests were performed. The blood glucose levels and motor activity were compared among four groups using generalized estimating equations to evaluate the effectiveness of interventions. Results: Totally 199 T2DM patients were enrolled, including 51 patients in the KN group, 49 patients in the K group, 52 patients in the N group and 47 patients in the C group. There were no significant differences in gender, age, course of disease, duration of daily exercises, waist-to-hip ratio, vital capacity or maximal oxygen uptake among the four groups prior to interventions (all P>0.05). There were time-group interaction effects in blood glucose and exercise parameters among the four groups post-interventions (all P>0.05), with the largest changes seen in the KN group. The HbA1c, 2 h postprandial plasma glucose, 2.4 m standing and detour test and back scratch test results reduced by 17.06%, 27.01%, 36.52% and 20.94% 12 weeks post-interventions as compared to those prior to interventions, while 2 min stepping test, 30 s sit-ups, 30 s loading and elbow flexion test, 6 min walking test and sit and reach test results increased by 18.85%, 34.69%, 15.41%, 7.22% and 112.37%, respectively. Conclusion High-intensity interval somatosensory training combined with neuromuscular acupoint electrical stimulation may improve the blood glucose and motor activity among patients with T2DM.

OBJECTIVETo introduce a new measuring tool for measuring postoperative limb length exactly, and to provide a convenient and effective method to control limb length after total hip replacement.

METHODSFrom January 2013 to September 2014, 102 patients undergoing primary unilateral hip replacement were divided into two groups: experimental group and control group. There were 51 patients in the experimental group, including 25 males and 26 females, ranging in age from 37 to 92 years old, with an average of 60.41 years old. The patients in experimental group were treated with new method to control limb length. Other 51 patients in the control group, including 27 males and 24 females, ranging in age from 35 to 87 years old, with an average of 61.00 years old. The patients in the control group were treated with normal methods such as shuck test or limb touching. All the patients were operated by the same experienced surgeon. In the experimental group,total hip arthroplasties (THA) were performed on 35 patients with avascular necrosis of the femoral head or femoral neck fracture, and 16 patients were treated with hemiarthroplasty (HA). In the control group, 38 patients received THA and 13 patients received HA. On the anterior-posterior X-ray radiograph, several indexes were measured as follows: the distance of bilateral femoral offset (a), the height from tip of great trochanter to the rotation center of the femoral head (b) and the vertical distance between the top of the minor trochanter and the two tear drops line (c). The leg length discrepancy can be assessed with three parameters as follows: d1, the absolute value of the difference between the bilateral a values; d2, the difference between the bilateral b values; d3, the difference between the bilateral c values. The SPSS 21.0 was applied for the statistical analysis.

RESULTSIn the experimental and control groups, d1 were 4.49 mm and 7.32 mm (P = 0.013); d2 were 2.37 mm and 4.32 mm (P = 0.033); d3 were 3.32 mm and 6.08 mm (P = 0.031). The values of d1, d2 and d3 in the experimental group were significant smaller than those in the control group.

CONCLUSIONThe new measuring tool and method can be used to control the limb length and offset effectively during operation.
