Objective To study the relativity between virtual touch tissue quantification(VTQ)and collagen percentage assay in the stiffness of primary liver cancer(PLC).Methods Forty patients with PLC were examined with virtual touch tissue quantification (VTQ)to obtain the shear wave velocity(SWV) before operation.These parameters were compared with collagen percentage assay counted with immunohistochemistry,and the correlation was statistically studied.Results Significant differences in mean SWV appeared between tumor tissues and background liver tissues of these PLC [2.82 ± 0.68 )m/s vs (1 .66±0.47)m/s,P <0.05].The collagen percentage assay of tumor tissues was significantly higher than that of background liver tissues [Sirius red group:(74.68 ± 1 1 .29)% vs (41 .59 ± 1 7.85 )%,P < 0.05;Masson group:(75.47 ± 1 1 .1 1 )% vs (40.41 ± 1 7.12 )%,P < 0.05 ].The SWV before operation was correlated positively to collagen percentage assay (Sirius red group:r =0.70,P <0.05;Masson group:r =0.73,P < 0.05 )of histological section after operation.Conclusions SWV value calculated by VTQ has reasonable correlation with collagen percentage assay of tumors,it is a valuable index for quantitative evaluation of the stiffness of liver cancer.

ObjectiveTo observe the effect of probucol combined with atorvastatin in treatment of stenosis carotid atherosclerosis.MethodsEighty-six patients with stenosis carotid atherosclerosis were separated into two groups with 43 cases each by random digits table.The patients were treated with probucol combined with atorvastatin in observation group and atorvastatin only in control group.The changes of arteriosclerotic plaque and blood fat pre- and poet-treatment were observed.Results There was no significant difference in the levels of lumen area (LN) and intima-media thickness (IMT) pre-treatment between two groups (P＞ 0.05).Compared with pre-treatment,the levels of LN and IMT post-treatment were significantly decreased in observation group(P ＜ 0.05 ),while no significant difference in control group (P ＞0.05).There was significant difference in the levels of LN and IMT post-treatment between two groups [(0.59 ±0.19) cm2 vs.(0.72 ±0.28) cm2,(2.76 ±0.41 ) mm vs.(3.27 ±0.57) mm](P＜ 0.05).There was no significant difference in the levels of total cholesterol (TC),triacylglycerol (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) pre-treatment between two groups (P ＞0.05).Compared with pre-treatment,the levels of TC,TG,LDL-C post-treatment were decreased,HDL-C was increased,there were significant differences (P ＜ 0.05 ).Post-treatment,the levels of TC,TG,LDL-C in observation group were lower and HDL-C was higher than those in control group (P ＜ 0.05).Conclusion Probucol combined with atorvastatin in treatment of stenosis carotid atherosclerosis can improve arteriosclerotic plaque and low blood fat,which can be applied in clinic.

Objective To discuss the application of ice-breaking action in the construction of nurse team, strengthen the cohesion of nurse team, therefore, to improve nursing quality. Methods First, let all nurses working in the same ward area to participate an action, namely ice-breaking action or secret angel action, in which every nurse chose secretly one of other nurses by drawing cards, then she often cared for that nurse secretly, namely she became a secret angel for that nurse. In return, she was also chosen and cared by one of others secretly. That means every nurse would become a secret angel, and owned a secret angel in the same time. Second, to test the change of happiness index of every nurse, the change of team's cohesion, and the change of patients' contentment indexes, before and after the secret-angel action was taken. Results Happiness indexes of 37 participants improved distinctly, and so did the contentment indexes of their patients after the secret-angel action was taken. Conclusions The secret-angel action can strengthen the cohesion of nurse team, improve happiness indexes of nurses, contentment indexes of their patients, and improve nursing quality.

Objective To explore the relationships among psychological empower, role stressors and job burnout in nurses.Methods From February to October of 2014, by random sampling method, 420 nurses from three hospitals of Jinzhou city of Liaoning province were selected and assessed with the psycho-logical empower questionnaires,the job burnout questionnaire,role stressors questionnaire.The data were ana-lyzed using pearson correlation analysis and logical multiple linear regression analysis.Results The average score of job burnout was (59.58±18.30) points, the average score of psychological empower was (38.87±7. 05) points.Job burnout and each dimension were negative correlated with self-determination of the psycho-logical empower ( r=-0.25--0.34, P<0.05) and self-efficacy ( r=-0.08--0.53, P<0.05).The scores of role stressors were positively correlated with the scores of emotional exhaustion( r=0.17-0.43, P<0.05) and cynicism ( r=0.07-0.46, P<0.05) .Multiple regression analysis showed that age(β=-0.104) ,education lev-el(β=-0.237),seniority(β=-0.334),self-determination(β=-0.152),self-efficacy(β=0.127),role am-biguity(β=0.284),role overload(β=0.325) were influencing factors of nursing burnout.Conclusion -Nurses role stressors and psychological empower can predict nurses’ burnout, so nurse managers can in-crease the level of authority to relieve psychological job burnout by reducing caregiver stress source.

Objective To investigate the level of self-management behaviors and the quality of life with gastro esophageal reflux disease(GERD) patients,and analyze the correlation between self-management level and quality of life.Methods A total of 372 GERD patients were investigated by using Self-management Behavior Scale and Mos 36-item Short Form (SF-36) Health Survey.Results The level of self-management behaviors in GERD patients was relatively low.The total score of quality of life was (48.75±7.59) and the scores of the level of self-management behaviors was (5.13±0.59).Correlation analysis showed that there was positive correlation between quality of life and self-management behaviors(r=0.423,P＜0.01).Conclusion To promote the patients' health status,nursing staff should take measures to strengthen patient health education on the level of self-management behaviors for GERD patients.

Objective To evaluate factors associated with labor pain and delivery outcomes.Methods From Jul.to Dec.2009,111 normal singleton cephalic presentation pregnancies (including 5 elderly parturient) who delivered at the Department of Obstetrics and Gynecology,Second Affiliated Hospital,Zhejiang Chinese Medical University were enrolled in this study to evaluate the relationship between factors of labor pain and delivery outcomes.The labor pain of latent phase and active phase were scored by the visual analogue scale (VAS).Factors associated with pain included the age of parturient,the number of gravidity and parity,occupation,education profile,dwell location,etc.The questionnaire was designed by ourselves.Childbirth awareness,psychological preparation of delivery,emotional controllability,couple relationship,the relationship of parturient and mother-in-law,the relationship of parturient and parents,family economic status,use of sedative during the labor process and delivery outcomes were collected and analyzed.Results (1)Factors associated with pain:in the latent phase,the rate of moderate labour pain of 1/5 in women with more than 35 years old was statistically lower than 76.4％ ( 81/106 ) in suitable age group (P＜0.05 ).The women with a good understanding about delivery had a statistically lower rate of moderate pain of 64.7％( 44/68 ) than 88.4％ ( 38/43 ) of those having a poor understanding( P＜0.05 ).The women who had a better couple relationship had a significandy higher rate of moderate pain of 77.2％ (78/101) than 4/10 of those who had a general couple relationship ( P＜0.05 ).There was significant difference in rate of moderate pain between pluripara group ( 50.0％,11/22) and primipara group(79.8％,71/89;P＜0.01 ).In the active phase,women with tense,scared or a poor emotion control expressed significantly severe labour pain(59.0％,36/61 ) than 35.6％ ( 16/45 ) in well-prepared group.The rate of severe labour pain in good control of emotion group of 44.8％ (43/96) was a statistically lower than 9/10 in poor control group.There was a statistically lower severe labour pain in women given by sedatives ( 29.2％,7/24 ) than 54.9％ (45/82) in women without sedatives treatment (P ＜ 0.05).(2) Delivery outcomes:in latent phase,the rates of fetal distress and cesarean section were 36.6％ (30/82) and 39.0％ (32/82) in moderate pain group,which were significantly higher than 13.8％ (4/29) and 17.2％ (5/29) in mild pain group.In active phase,the rate of fetal distress,cesarean section and postpartum hemorrhage were 36.5％ ( 19/52),40.4％ (21/52) and 13.5％ (7/52) in severe pain group,which were significantly higher than [18.5％ (10/54) ;20.4％ (11/54) ;0] in moderate pain group (P＜0.05).Conclusions Women with poor understanding of delivery,tense,scared,poor emotion control,young age and uniparous have severe labour pain.Sedative use could alleviate pain in active phase.Women with mild labour pain have good delivery outcomes.

Objective:To investigate the clinical value of neck vascular ultrasound and homocysteine (Hcy) level in patients with cerebral infarction and carotid stenosis.
Methods: Our research included 2 groups. Cerebral infarction group, n=115 patient who were treated in our hospital from 2012-01 to 2013-12, and Control group, n=110 healthy subjects from physical check-up. Neck vascular ultrasound was conducted to classify the degree of carotid stenosis as ①no stenosis, ②mild degree, the stenosis rate≤29%, ③moderate degree, the stenosis rate at 30%~69%,③severe degree, the stenosis rate at 70%~99%,④complete occlusion. Carotid plaque formation and vascular intima-media thickness (IMT) were examined by neck ultrasound. Blood levels of Hcy and triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) were
measured in clinical laboratory.
Results: Compared with Control group, Cerebral infarction group had the higher rate of carotid stenosis 89.56%vs 10.91%, more plaque formation 73.91%vs 6.08%and increased IMT (1.85 ± 0.42) mm vs (0.75 ± 0.21) mm;higher blood levels of Hcy (42.32 ± 12.02) μmol/L vs (6.32 ± 2.45) μmol/L and higher rate of high blood Hcy syndrome 71.30%vs 3.63%;higher levels of TC (4.25 ± 1.12) mmol/L vs (1.63 ± 0.74) mmol/L and LDL-C (5.96 ± 1.36) mmol/L vs (2.32 ± 0.82) mmol/L, P<0.05. In Cerebral infarction group, the patients with complete carotid occlusion and severe stenosis had the higher rate of plaque formation and increased IMT;higher levels of Hcy and more high blood Hcy syndrome;higher levels of TG and LDL-C than the patients with mild and moderate carotid stenosis, P<0.05. Logistic analysis indicated that the levels of IMT, Hcy and LDL-C were the independent risk factors for cerebral infarction and carotid stenosis.
Conclusion: The patients with cerebral infarction and carotid stenosis have obviously increased blood level of Hcy. Hcy may predict various degree of carotid stenosis in relevant patients.

Objective:To study the prognosis factors of idiopathic sudden hearing loss. Method:The clinical data of 165 patients with idiopathic sudden hearing loss were retrospectively studied and the computer software was used to investigate the relevant effects on prognosis. Result:The prognosis of patients who had been treated within 14 days under the age of 55 were better. The prognosis of the elderly and the patients with vertigo and high hearing loss were not satisfied. Sex, tinnitus, cardiac or cerebral vascular diseases, diabetic and the medicine or the duration of treatment have no statistical points on prognosis. Conclusion:The prognosis of idiopathic sudden hearing loss related with the treatment time and coverage and extent of the damaged inner ear.

Objective To investigate the relationship between abnormal bone mineral density (BMD) and subclinical thyroid dysfunction. Methods Thyroid function, biochemical indicators of bone metabolism and BMD were reviewed retrospectively in the subjects who received health checkups from July 1, 2009 to January 31, 2017 in the Health Check-up Department of Peking Union Medical College Hospital. People who had thyroid dysfunction, recognized risk factors for osteoporosis, and medication history were excluded. A cross-sectional analysis of thyroid status and biochemical indicators of bone metabolism was performed by the standard methods. BMD at the lumbar spine and femoral neck was measured using dual energy X-ray absorptiometry. Results A total of 6884 subjects (3726 women and 3158 men) were enrolled in the study, with an average age of (50.74 ± 10.41) years. They were divided into three groups:subclinical hyperthyroid, subclinical hypothyroid, and euthyroidism. The alkaline phosphatase in subclinical hyperthyroid group was higher than that in the euthyroidism group[ (67.95±20.64)U/L vs. (63.88±18.99)U/L]. Calcium and phosphorus in blood were higher in both subclinical hyperthyroid and subclinical hypothyroid groups. The rate of abnormal BMD in male euthyroidism, subclinical hyperthyroid and subclinical hypothyroid groups were 36.10％(1049/2906), 29.27％(12/41) and 27.01％(57/211), respectively. The rate of abnormal BMD showed no difference between subclinical hyperthyroid group and euthyroidism group (P>0.05). The rate of abnormal BMD was lower in subclinical hypothyroid group than in euthyroidism group (χ2=7.0901, P<0.01), especially in the males aged 40-49 years (χ2=10.4618, P<0.01). The rate of abnormal BMD in female euthyroidism, subclinical hyperthyroid and subclinical hypothyroid groups was 38.81％(1286/3314), 45.83％ (33/72) and 40.88％ (139/340), respectively. The rate of abnormal BMD showed no difference among the three groups (P>0.05). Conclusion There is no significant difference in the rate of abnormal BMD between subclinical thyroid dysfunction group and euthyroidism group, possibly because abnormal serum biochemical indicators preceded the presence of low BMD. More sensitive methods used to determine the status of bone metabolism await to be developed.
