Objective:Three-dimensional (3D) ultrasound (US) is increasingly being introduced in the clinic,both for diagnostics and image guidance.Although dedicated 3D US probes exist,because of its expensive cost,3D US can also be acquired with the still frequently used two-dimensional (2D) US probes.Methods:Obtaining 3D volumes with 2D US probes is a two-step process.First,a positioning sensor must be attached to the probe for 2D image matching;second,a reconstruction of a 3D volume can be performed into a regular voxel grid.Results:This paper presents a way to realize the 3D US in irled-based Image Guided Radiotherapy using a homemade 2D US.Conclusions:The experiments demonstrate a method of saving costs and having advantages in clinic application.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

Objective To evaluate the clinical value of 131 Ⅰ SPECT/CT in the differentiation of indeterminate 131Ⅰ uptake on planer whole body scan (WBS) for patients with DTC after 131Ⅰ treatment. Methods Fifty-six DTC patients ( male: 19, female: 37, mean age: 45 ± 15 years, ranging from 20 to 85 years) underwent 131Ⅰ treatment. 131Ⅰ WBS was performed five days after 131 Ⅰ treatment, followed by regional 131Ⅰ SPECT/CT for the indeterminate foci with abnormal uptake on 131Ⅰ WBS. The diagnostic difference of the two imaging modalities was compared by x2 test. Results There were 288 foci with abnormal uptake on 131 Ⅰ WBS, including 108 indeterminate foci (37.5%). Subsequent 131Ⅰ SPECT/CT identified 27 foci as DTC metastases (25.0%) and 71 foci as non-metastases such as benign lesions at nose, oral cavity, salivary gland, maxillary cyst, thyroid remnant, thymus, gallbladder, gastrointestinal tract, and uterus, or non-specific uptake of body contaminations (65.7%). However, the remaining 10 foci (9.3%) remained indeterminate on 131 Ⅰ SPECT/CT imaging. The diagnostic accuracy of 131 Ⅰ SPECT/CT was significantly higher than that of 131Ⅰ WBS (x2 = 102.35, P<0. 01). Conclusion 131Ⅰ SPECT/CT could significantly improve the diagnostic accuracy for the differentiation of indeterminate foci with abnormal uptake on 131Ⅰ WBS.

OBJECTIVETo investigate the effect of Uncaria rhynchophylla total alkaloids (RTA) pretreatment on the voltage-gated sodium currents of the rat hippocampal neurons after acute hypoxia.
METHODPrimary cultured hippocampal neurons were divided into RTA pre-treated and non-pretreated groups. Patch clamp whole-cell recording was used to compare the voltage-gated sodium current amplitude and threshold with those before hypoxia.
RESULTAfter acute hypoxia, sodium current amplitude was significantly decreased and its threshold was upside. RTA pretreatment could inhibit the reduction of sodium current amplitude.
CONCLUSIONRTA pretreatment alleviates the acute hypoxia-induced change of sodium currents, which may be one of the mechanisms for protective effect of RTA on cells.

OBJECTIVETo investigate characteristics of treating dislocation and fracture of sacroiliac joint through anterior and posterior approaches.
METHODSBetween January 2006 and September 2012, 39 patients with dislocations and fractures of sacroiliac joint were treated with operation. There were 28 males and 11 females, aged 12 to 64 (mean, 41.3) years old. Seventeen cases were chosen through anterior approach, 13 cases through posterior and 9 cases were combined with anterior and posterior approaches. The anterior approach were made with supine position, performed open reduction, and two plates with 4 holes were used as internal fixation for arthrodesis of sacroiliac joint after reduction; while posterior approach prone position, close or open reduction was performed, and one or two partial thread lag screws, which with 7.3 mm in diameter and 60 to 75 mm in length, were penetrated via sacroiliac joint for fixation under X-ray. Postoperative complications were observed, Matta and Majeed scoring were used to evaluated currative effects.
RESULTSAll patients were followed up from 6 to 36 months. The patient could sit on the bed 2 to 4 weeks after surgery and walk with a crane 6 weeks' later. No breakage or loosening of screw occurred during follow-up. In all but one case with old sacral iliac fractures reducted poor, others obtained good opposition. According to Matta's criteria, 30 cases got excellent results, 8 good and 1 fair. According to Majeed's funtional standard, 14 patients got excellent results, 20 good 4 fair and 1 poor.
CONCLUSIONTreating dislocation and fracture of sacroiliac joint through anterior and posterior approaches can obtain good effects. However, anatomic location, fracture types, degree of displacement, the rate of preoperational reduction, vulnerability assessment of operation and fixation strength should be considered.
