Purpose To explore the correlation between whole body magnetic resonance diffusion-weighted imaging (WB-DWI) quantitative parameters of healthy adults' bone marrow with gender, age, height, weight, body mass index, and sex hormone levels. Materials and Methods 108 healthy adult subjects in different age groups underwent WB-DWI scan using GE 1.5T MR scanner, among them estradiol and progesterone levels were measured in 60 subjects within 48 hours before or after the scan. Apparent diffusion coefficient (ADC) values of bone marrow and the signal to noise ratio (SNR) were compared among different gender and age groups. Partial correlation analysis was used to evaluate the correlation of skeletal system ADC values and SNR with sex, age, height, weight, body mass index, estradiol and progesterone levels in 60 subjects. Results ADC values and SNR of the female subjects were significantly higher than males (P<0.01);there were significantly differences for skeletal system ADC values and SNR in different age groups (P<0.01). Skeletal system ADC values was significantly negatively correlated (r=-0.642, P<0.01) with age, and were mildly positively correlated (r=0.278, 0.271, P<0.05) with estradiol and progesterone levels;SNR was significantly negatively correlated (r=-0.709, P<0.01) with age, and was mildly positively correlated (r=0.293, P<0.05) with estradiol levels;ADC values and SNR had no significant correlation with height, weight and body mass index. Conclusion Skeletal system ADC values are effected by gender, age and sex hormone levels, the skeletal system WB-DWI manifestations are different in different gender and age groups.

0bjective To evaluate the application of whole body MR diffusion weighted imaging (DWI)in the detection of bone metastasis using skeletal scintigraphy as the referenee.Methods Fonv.two healthy volunteers and 38 patients with malignant tumors were enrolled in our studv.A11 the patients received MR examination and skeletal scintigraphy within one week.MR examination was performed on GE signa 3.0T MR scanner using a build.in body coil.The skeletal system Was divided into eight regons and the images of the whole body MR DWI and skeletal seintigraphy were reviewed to compare the two modalities patient by patient and region by region.The images were reviewed separately by two radiologists and two nuclear medicine physicians,who were blinded to the results of another imaging modality.Results A total of 169 metastatic lesions in 69 regions of 30 patients were detected by whole body MR DWI while 156 lesions in 68 regions of 29 patients were identified by skeletal seintigraphy.There were two cases negative in scintigraphy but positive in whole body MR DWI and one case positive in scintigraphy only.There were eight lesions negative in scintigraphy but positive in whole body MR DWI,mainly located in the spine.pelvis and femur.Seven 1esions were only detected by scintigraphy,mainly located in the skull.sternum.clavicle and scapula.Conclusion The whole body MR DWI reveals excellent consistency with skeletal scintigraphy regarding bone metastasis.and the two modalities are complementary for each Other.

In order to summarize and perfect the basic skill practicing method in acupuncture teaching and form a characteristic teaching, the research on skill training and technique improving of acupuncture and tuina major was carried out. The undergraduate students in acupuncture and tuina major from College of Acupuncture-Moxibustion and Tuina were randomly divided into an experimental group and a control group. Students from both groups received the basic courses of acupuncture-moxibustion and tuina as requested in the syllabus and the special teaching was added to the experimental group, namely "three practice" (strength practice, coordination practice, targeted practice of acupuncture basic skills) and "three enlightenment" (technique enlightenment, mind and qi enlightenment, efficacy enlightenment). During and after the courses, the teaching effectiveness was evaluated on the basis of needling manipulation. The peacetime score in the experimental group was superior to that in the control group (38.03 +/- 1.14 vs 33.25 +/- 1.31, P < 0.05), the total score in the experimental group was superior to that in the control group (84.03 +/- 6.30 vs 78.05 +/- 6.55, P < 0.05). The special teaching method of "three practice" and "three enlightenment" can improve the effect of skill training teaching method. It highlights the unique feature of central plains by integrating the essence of Shaolin internal qigong and Chen-style Taiji, it can also provide new ideas for the practical teaching of TCM professional courses and the construction of characteristic professionals.

AIM:To observe the pathological changes of the lower segment of nasolacrimal duct mucosa in rabbits at different stages after retrograde lachrymal dilated drainage tube implantation.
METHODS:Totally 14 New Zealand rabbits were used in the present study. One side of nasolacrimal duct was obstructed to produce an experimental model and operated the reverse implantation of nasolacrimal duct intubation. Histological changes of the lower segment of nasolacrimal duct mucosa were observed by routine light microscope at 2, 4, 6, 8, 10, 12 and 14wk after the operation.
RESULTS: Compared with the control side, the group of 2 and 4wk after surgery presented the inflammatory cytokine. The group of 12wk after the operation presented isolated granuloma. Group 12 and 14wk presented scattered granuloma. The size of the granulomas was smaller and the density of epithelioid cell and fibroblast were lower in group 12wk than those in group 14wk by HE and Masson trichrome stain.
CONCLUSION:Recurrent Silicone Tube is used to treat nasolacrymal duct obstruction. Nasolacrimal duct can be narrowed and blocked again by granuloma, progressive fibrosis and adhesion of surrounding tissues when tube is in the duct more than 12wk.

Objective To translate the English version of the Intuitive Eating scale-2( IES-2) into Chinese,and test the reliability and validity of the Chinese version of IES-2(IES-2-CHI) in college students. Methods The reliability and validity of the Chinese version of IES-2 were tested among 1 309 college students in Liaoning province. All data were analyzed by SPSS 20. 0 and AMOS 21. 0. Results The Chi-nese version of IES-2-CHI, all inter-items and item-to-total correlation coefficients ranged from 0. 444 to 0. 759. The IES-2-CHI had a total Cronbach’s α of 0. 933 and the test-retest correlation was 0. 831. The i-tem-level content validity index(I-CVI)ranged from 0. 830 to 1. 000,the scale-level content validity index(S-CVI/UA)was 0. 870,and the content validity index at the average scale level(S-CVI/Ave)was 0. 978. Four-factors(unconditional permission to eat,eating for physical rather than emotional reasons,reliance on hunger and satiety cues,body-food choice congruence) model were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 58. 974%. The confirmatory factor analysis results showed that χ2/df=2. 941,CFI=0. 959,GFI=0. 920,TLI=0. 954,PGFI=0. 747,RMSEA=0. 055,and the model was basically adaptable. Conclusion The Chinese version of IES-2-CHI scale is reliable and valid instrument, which can be used to measure the level of intuitive eating among the college students in Liaoning province.

Objective To explore the best time point for the ipsilateral hepatocellular apoptosis and the contralateraI hepatic hypertrophy after selective portal vein embolization(SPVE)in rabbit.Methods In a randomized study design,forty rabbits were divided into 5 groups with 8 rabbits per-group,including one as the control and the other 4 were treated with SPVE during open surgery.The rabbits were killed postoperatively,in 3,7,14,21 days respectively after the embolization.The hepatic lobes volume,the ipsilateral hepatocellular necrosis rates and apoptosis index,and liver functions were determined as well. Results In the treatment groups,the average amount of the right liver volumes decreased from 46.4 cm~3 preoperatively to 46.0,44.4,42.0,39.7 cm~3 in groups of 3,7,14,21 days postoperatively;meanwhile,the left liver volumes increased from 54.0 cm~3 preoperatively to 54.5,56.3,61.7,63.9 cm~3 respectively during 3, 7,14,21 days after the procedures.The rates of future remaining live volumes(FRLV)increased from 53.8% preoperatively to 54.2%,55.9%,59.0%,61.0% at 3,7,14,21 days postoperatively.The apoptosis indexes of hepatocells from group A to E were 8.1%,12.2%,19.4%,20.1%,14.2% respectively.Conclusions SPVE leads to atrophy of the ipsilateral hepatic lobe and hypertrophy of contralateral lobe,indicating that hepatocytes undergone apoptosis,rather than necrosis.The time point is 7 to 14 days.

OBJECTIVETo analyze the influence of intravesical Pirarubicin (THP) instillation on the prediction results of European Organization for Research and Treatment of Cancer (EORTC) risk tables and to discuss the efficacy of EORTC risk tables in clinical application.

METHODSWe retrospectively reviewed the clinical data of 389 patients with non-muscle invasive bladder cancer after TURBT treated with intravesical pirarubicin instillation. According to the EORTC Scoring System, all the cases were divided into low risk group, intermediate risk group and high risk group. The 1-year and 5-year recurrence and progression rates of each group were calculated and compared with the prediction results of the EORTC risk tables.

RESULTSThe 1-year recurrence and progression rates of the low risk group were 8.0% and 0, those of the intermediate risk group were 31.0% and 2.8%, and those of the high risk group were 52.5% and 18.6%, respectively. The 5-year recurrence and progression rates of low risk group were 16.0% and 5.3%, those of the intermediate risk group were 42.6% and 10.7%, and those of the high risk group were 63.9% and 41.9%, respectively. The prediction results of progression rate were similar to that of the EORTC risk tables while the overall recurrence rate was lower.

CONCLUSIONSThe EORTC risk tables can be effectively used to predict the recurrence rate and progression rate of non-muscle invasive bladder cancer. However, the EORTC risk tables have a tendency to overestimate the recurrence rate. Intravesical pirarubicin instillation is helpful to reduce the recurrence rate, yet has no obvious influence on the tumor progression.
