To correlate the ultrasound and MR imaging of carotid atherosclerotic plaque with its histologic compositions,20 patients(22 lesions) scheduled for carotid endarterectomy were examined by B mode ultrasound and MRI preoperatively. The specimens were also examined postoperatively and the images of carotid plaque were recorded. The transverse pathological sections of plaques were made and matched with images of ultrasound and MRI. 256 gray scale ultrasound densitometric analysis of carotid plaque compositions was performed. Ultrasonic density of calcium, fibrous tissue, hemorrage/thrombus and lipid deposits was (89?12), (53?8), (37?6) and (39?3) respectively in vivo , and was (168?11), (136?12), (85?12) and (89?10) respectively in vitro . In vivo relative signal intensities of calcium, fibrous tissue, old hemorrhage/thrombus and lipid deposits were low, equal, equal and very high respectively on T 1 W MR image, and very low, equal, high and high respectively on PDW MR image, and low, equal or slightly high, high and high respectively on T 2 W MR image. Signal intensities of plaque contents ex vivo were correlated to signal intensities in vivo. Densitometric analysis of ultrasound images of carotid plaques can quantify possible components of plaque, and MRI has the feasibility to identify the components of plaque.

To study the distribution of two different phenotype mast cells in atherosclerotic lesions of human carotid arteries, 32 samples of endarterectomy and 10 autopsies of normal carotid specimens were fixed and embeded in paraffin, sections were stained with hematoxylin-eosin, toluidine blue,monoclonal antibodies against the two major proteases of mast cells(tryptase and chymase) and monoclonal antibodies against CD-3 of T lymphocytes and CD-68 of macrophages. The quantity,distribution and degranule of two different phenotype mast cells in atherosclerotic lesions of human carotid arteries were investigated,and the ratio of mast cells to T lymphocytes and macrophages in atherosclerotic lesions was calculated. The density(cells/mm 2 ) of mast cells in shoulder region of plaque(6 3?4 0) was much higher than that in normal intima,cap and core region(1 3?2 3,2 3?2 6,2 2?3 7) .The proportion of chymase-containing mast cells to tryptase-containing mast cells was 0 36,0 51,0 47 and 0 39 respectively in normal intima,cap,core and shoulder region of plaque.The propotion of degranulated mast cells was the highest in shoulder region of plaque(65%).The ratios of mast cells to T lymphocytes and to macrophages were 0 25 and 0 14 respectively in shoulder region of plaques.Light microscopic studies of mast cells revealed that mast cells were more commonly observed in thrombus and around calcification and blood vessels of plaque.Mast cells play a role in the formation of plaque,and participate in the destabilization of plaque.

Objective To compare the serum index after colonoscopy high-frequency electric snare combined with nylon cord ligation and high-frequency electric resection in treating broad pedicle polyps. Methods 70 cases of broad pedicle polyps patients from July 2012 to May 2016 were chosen as research object. The operation methods and laboratory examination results of all the patients were reviewed. All patients were divided into observation group (n = 37) and control group (n = 33). Patients in observation group were treated by colonoscopy high-frequency electric snare combined with nylon loop ligation, while patients in control group were treated by high-frequency electric resection only. The blood loss and related indexes of the two groups were recorded. Before and after operation, stress hormones and acute phase proteins in serum was determined. Results Intraoperative blood loss of observation group was less than that in control group, postoperative hemoglobin levels was higher than that in control group, postoperative early bleeding rate, postoperative delayed bleeding rate of observation group were lower than that in control group (P < 0.05); 1 hour after surgery, Cor, ACTH, AT II, NE, CRP, SAA, AAT in serum were lower than those in control group (P < 0.05). Conclusion Through colonoscopy high-frequency electric snare combined with nylon cord ligation can reduce bleeding during and after surgery, relieve stress and inflammation.

Objective To observe the effects of labor analgesia on maternal and neonatal outcome by epidural application of 0.125% bupivacaine combined with anisodamine on the labor stage, and modes of delivery and neonatal Apgar's score. Methods A total of 220 primiparaes with full-term pregnancy, monocyesis and fetal head presentation without any obstetrical or systematic complications were chosen and divided into analgesic group and control group (110 in each group). The mixture of bupivaeaine and anisodamine was injected into the epidural space of the parturients in the analgesic group while those patients in the control group did not receive any analgesics. Results The analgesic effect was satisfactory (91.8 %), and no side effects occurred in the second stage of labor. The instrument delivery rate was lower in the analgesic group, and there was no significant difference between the two groups in neonatal Apgar's score. Conclusion The method is feasible in clinic for labor pain relief without increasing the rate of dystocla and complications of delivery.

Osteopontin (OPN) is a secreted O-glycosylated phosphoprotein that exists in a variety of tissues and body fluids, with a variety of biological activity. Integrin α_vβ_3 is the main receptor. OPN mainly involves in cell proliferation, differentiation, migration and adhesion. The study of OPN at home and abroad mainly focuses on the bone resorption, angiogenesis, atherosclerosis, digestive system, urinary system, wound healing, skin fibrosis, liver fibrosis, kidney fibrosis, etc.But reports about OPN in pulmonary fibrosis are much less, now the relationships between OPN and pulmonary fibrosis are reviewed.

Objective To detect whether and where brain functional connectivity exists in the resting state of patients with early-onset schizophrenia by using functional magnetic resonance imaging (fMRI). Methods Nineteen early-onset schizophrenic patients were diagnosed with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) of American Psychiatric Association. The 19 early-onset schizophrenic patients and another 19 healthy volunteers underwent fMRI in resting state. Cingulate gyrus was selected as region of interest and the difference was analyzed in the cingulate gyrus functional connectivity pattern between the 19 patients with early-onset schizophrenia (EOS) and 19 matched controls using resting-state fMRI. A two-sample t test was performed on the individual in a voxel by voxel manner. Results Statistical map was set a combined threshold of P＜0.005 and the number of voxel>20. Functional connectivity in the resting state was abnormal in the patients,including decreased functional connectivity and increased functional connectivity. The abnormal area was distributed all over the brain. The brain area with decreased functional connectivity included bilateral posterior cerebellar lobes, superior frontal gyrus, middle frontal gyrus, gyrus rectus,hippocampus, cuneus gyrus,fusiform gyrus,middle occipital gyrus,inferior occipital gyrus, right inferior temporal gyrus,right middle temporal gyrus, and right angular gyrus. The brain area with increased functional connectivity included left middle temporal and left inferior temporal gyrus. Conclusion Abnormal cingulate gyrus functional connectivity of schizophrenia might exist in the resting state. Resting state fMRI is important for the research of schizophrenia.

Objective To evaluate clinical effect of accurate pedicle subtraction osteotomy (PSO) using osteotomes in the treatment of thoracolumbar kyphosis (TLK).Methods From June 2007 to October 2010,18 patients with TLK underwent accurate PSO using osteotomes under X-ray fluoroscopy,including 13 males and 5 females,with an average age of 48.6 years.The primary causes of TLK included old fracture (11cases),chronic tuberculosis (4 cases) and hemivertebra (3 cases).Deformity apex occurred at T12 (5 cases),L1 (9 cases),and L2 (4 cases).Radiological assessment for sagittal balance was performed by measuring Cobb angle.The Frankel grade,visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate pre-and post-operative neurological status,back pain and function.Results The mean operative time,mean blood loss and mean postoperative drainage volume were 247.0±29.3 minutes,708.5±34.5 ml and 337.3±74.6 ml,respectively.All patients were followed up for 1 to 4.5 years (average,2.8 years).Solid fusion was achieved in all patients.Cobb angle was corrected from preoperative 42.3°±5.7° to 2.2°±1.9° three months postoperatively and 2.7°±2.1 ° at final follow-up.VAS and ODI scores decreased from preoperative 8.5±1.0 and 72.8％±8.3％ to 2.1±0.7 and 21.6％±9.2％ three months postoperatively,and 1.9±0.6 and 19.3％±8.6％ at final follow-up,respectively.With regard to Frankel grade,a 1-grade and 2-grade improvement was observed in 7 cases and 2 cases 3 months postoperatively,respectively.At final follow-up,a 1-grade and 2-grade improvement was observed in 5 cases and 4 cases,respectively.Two patients had transient neurological symptoms postoperatively,which recovered after drug treatment for 2 weeks.No other complications occurred.Conclusion It is safe and effective to correct TLK through accurate PSO using osteotomes,which has some advantages,such as less blood loss,higher fusion rate and fewer complications.
