Objective To investigate and compare the clinical value of the elastic grades score evaluation method and ultrasound elasticity imaging strain ratio method in identifying thyroid nodules.Methods A total of 120 cases confirmed by operation and pathology of the patients with thyroid nodules in our hospital were underwent ultrasound elasticity imaging detection,the thyroid nodules were identified with the elastic grades score evaluation method and ultrasound elasticity imaging strain ratio method respectively,and were compared with pathological results separately.Results The sensitivity,specificity and accuracy rate were 79.4％,81.3％,81％ with the elastic grades score evaluation method,the sensitivity,specificity and accuracy rate were 91.2％,90.3％,93.3％ with ultrasound elasticity imaging strain ratio method,of which was significantly higher with ultrasound elasticity imaging strain ratio method than with the elastic grades score evaluation methodby statistical analysis(x2 =28.170,P =0.000;x2 =34.219,P =0.000; x2 =17.928,P =0.000).Conclusion Ultrasound elastography strain ratio and rating score evaluation method can be used as an effective method in differentiating malignant from benign thyroid nodules,which can effectively improve the accuracy rate of the differential diagnosis of thyroid nodules and effectively remedy the diagnostic error band to cognitive differences with traditional ultrasound evaluation.The method of ultrasound elastography strain rate ratio was better with advantages of easy to operate,easy to learn and master,and easily accepted by patients,which is worthy of clinical application.

As the diagnosis and treatment levels increased, the cure rate and lifetime of the patients with breast cancer improved. In China,surgery and drug treatment received more attention, but the overall rehabilitation was ignored. This article summarized the status of breast cancer patients's rehabilitation in lymphoedema, upper limb dysfunction, psychological problem, sexual dysfunction, childbirth trouble,dystrophy, follow-up visit and family-society support, and so on.

Medical postgraduates are the future core force of clinical diagnosis and treatment,scientific research,education and sanitary administration.Therefore,to cultivate qualified professionals,the key of contemporary medical postgraduate education is to pay more attention to comprehensive quality training in order to make students adapt to the continuous development of society and medical model.The First Clinical College in Wuhan University has implemented the hospital administration internship in combination with social needs and explored the education model of contemporary medical students with comprehensive quality.

In order to study the values of MR/CT to the diagnosis, differential diagnosis, treatment and prognosis of systemic lupus erythematosis with neuropsyehiatric disorders (SLE-NP), MR/CT image changes of 22 examinations of skull/spinal cord in 16 patients with SLE-NP were analyzed. The results showed that the images of 18 examinations were abnormal (81.8%), including ischaemia/infarct (9 times), haemorrhage (3 times), focal demyelination (3 times), and cerebral atropy (6 times). The areas involved including basal ganglia (10 times), anterior horn of lateral ventricle (5 times), pons (1 time), and spinal cord (2 times). MR/CT is sensitive for the examination of lesions of SLE-NP, and the total positive rate is as high as 81.8%. Its high resolution rate can display the nature and areas of the lesions, which may provide valuable reference for the early diagnosis, differential diagnosis, treatment, evaluation of therapeutic efficacy and prognosis of SLE-NP.

Objective To construct an recombinant adenovirus vector of vascular endothelial growth factor small interfering RNA(Ad5-VEGFsi) and to observe its inhibitory effect on the cell proliferation of human leukemia K562 cells. Methods The specific human VEGF siRNA was subcloned into the shuttle plasmid pSES-HUS and then cotransfected with plasmid pAdeasy-1 to produce pAd5-VEGFsi by homologous recombination. The identified recombinant plasmid pAd5-VEGFsi was packaged and amplified in 293 cells. At 72 h after the transfection of Ad5-VEGFsi into K562 cells, VEGF mRNA expression and the protein level of VEGF in the cell culture supernatant were determined by RT-PCR and ELISA, respectively. Cell proliferation was measured by MTT assay and cell apoptosis by flow cytometry. Results The recombinant adenovirus Ad5-VEGFsi was successfully constructed. Ad5-VEGFsi with the titer of 4.6?1011 pfu/ml was harvested by CsCl gradient purification. Compared with those in the control, EGF mRNA in cells decreased by 66.55% (P

Objective To study the effects of ? carotene on rat liver fibrosis induced by carbon tetrachloride (CCl 4). Methods ① After being treated with CCl 4 for 3 weeks to induce the experimental rat liver fibrosis, rats were treated with ? carotene 250 000 U/kg body weight by oral feeding twice a week. The normal and the CCl 4 control group were also set. ② The liver pathological and ultrastructual change were studied. The content of rat liver hydrooxylproline, the expression of ? 2 (Ⅰ) collagen RNA and transforming growth facter ? 1 (TGF ? 1) were studied at the same time. Results In the treatment group, the liver fibrosis scores were fewer significantly than those in the CCl 4 group ( P

Objective To determine the effective target plasma propofol concentration required to prevent the response to fibercolonoscope examination in 50% of patients (EC50) .Methods Sixty ASA Ⅰ or Ⅱ patients aged 18-60 yrs weighing 45-70 kg undergoing fibercolonoscope examination were enrolled in this study. The initial target plasma propofol concentration was set at 5.0 ?g?ml-1 . EC50 was determined by up-and-down sequential experiment. The effect of TCI of propofol was based on the movement on the movement of the body in response to fibercolonoscope examination. If effective the target plasma propofol concentration was set at a lower concentration in the next patient and vice sersa. Each time the target plasma propofol concentration increased/decreased by 0.5 ?g?ml-1. The up-and-down sequences were analyzed by using the Dixon and Massey method to determine the EC50.Results The EC50 of propofol for fibercolonoscope examination was 4.9 ?g?ml-1 [95% confidence interval (CI) 4.5-5.4 ?g?ml-1] . Four patients developed respiratory depression during examination (6.67%). Conclusion The EC50 of propofol for fibercolonoscope examination is 4.9 ?g?ml-1.
