Objective To investigate the diagnostic value of breast MRI in patients presenting with microcalcifications on mammography.Methods Eight four patients were retrospectively analyzed,who had mammographically detected BI-RADS (breast imaging reporting and data system) 3 to 5 microcalcifications and underwent breast MRI before surgical biopsy.All mammography and MR images were reviewed with BI-RADS.With histopathological diagnosis as golden standard,the sensitivity,specificity and accuracy of the two methods were calculated and compared with x2 test or Fisher exact test.The diagnostic efficacy of the two methods was compared with ROC curve.Results Pathologic examination revealed 91 lesions in 84 patients including 49 benign lesions and 42 malignant lesions.For 21 lesions of category 3 microcalcifications,the specificity of mammography and MR was 100.0％ (21/21) and 95.2％ (20/21),which had no significant difference (P=1.000).For 51 lesious of category 4,sensitivity,specificity and accuracy of mammography were 100.0％(23/23),0 and 45.1％(23/51).The corresponding values for MR were 91.3％(21/23),82.1％ (23/28) and 86.3％ (44/51).The difference for specificity and accuracy between the two methods was statistical significant(x2 value was 30.030 and 19.182,respectively,with P＜0.01),but not for sensitivity(x2=0.523,P=0.470).Nineteen lesions of category 5 were all correctly diagnosed on mammography and MRI.For all the 91 lesions,the sensitivity,specificity and accuracy of mammography were 100.0％(42/42),42.9％(21/49) and 69.2％(63/91),respectively.The corresponding values for MRI were 95.2 ％(40/42),87.8％(43/49) and 91.2％(83/91).There was significant difference for specificity and accuracy between the two methods (x2 value was 21.798 and 13.851,respectively,with P＜0.05),but not for sensitivity (x2=0.512,P=0.474).The areas under ROC curve for mammography and MR were 0.844,0.945(P＜0.01),for the estimation of the benign and the malignent.Conclusions Compared with mammography,breast MRI significantly improved the diagnosis of category 4 microcalcifications with increased specificity and accuracy.But for microcalcifications of category 3 and 5,MR didn't improve the diagnostic effect.

Objective To improve the effects of health education(HE)and satisfaction degree on HE of inpatients by executing hierarchical full-responsibility nursing. Methods Fourteen wards were randomly chosen form the hospital and divided into the control group and the experimental group, each group having 7 wards. The control group carried out routine holistic nursing model, and the experimental group carried out a new hierarchical full-responsibility nursing system. Reforming nursing scheduling and diminishing the nursing unit to assure that the patients acquired the continous and stable nursing service when they were in hospital. The effect and the degree of satisfaction of HE were compared between two groups after 6 months. Results The effects of HE in the experimental group were significantly better than those in the control group, and the degree of satisfaction on HE in the experimental group was much higher than in the control group. Conclusions The hierarchical full-responsibility nursing system can give patients systematic and normalized HE. It can significantly improve the effects and the degree of satisfaction on HE.

Objective To assess whether the plaque volume of carotid artery evaluated by three-dimensional ultrasound can predict the risk of cardiovascular events earlier in patients with coronary heart disease, in comparison with plaque thickness.Methods A total of 99 patients were enrolled, including 66 patients with asymptomatic carotid plaque and 33 patients with coronary heart disease (CHD) and carotid plaque.Three-dimensional ultrasound was performed in all the patients.Coronary angiography was performed in all the patients in CHD group.Coronary artery Gensini score was calculated.Plaque thickness, plaque area and plaque volume were compared between the two groups.We analyzed the relationship of plaque volume with Gensini score and other cardiovascular risk factors.Results Plaque volume was significantly higher in CHD group [(1312.38±513.70)mm3] than in asymptomatic group [(947.54±321.41)mm3] (P=0.023).However, plaque thickness and plaque area were not significantly different between the two groups (P>0.05).Plaque volume was positively correlated with Gensini score (r=0.519, P=0.002), homocysteine (r=0.569, P=0.002), and cardiovascular risk factors such as diabetes, blood glucose and glycosylated hemoglobin.There was a negative correlation between plaque volume and high-density lipoprotein (HDL), a factor protecting against cardiovascular events (r=-0.387, P=0.038).Conclusion Compared with plaque thickness, the volume of carotid plaques assessed by three-dimensional imaging technique may be a better predictor of the risk of cardiovascular events in patients with coronary heart disease.

In recent years, the number of ICU survivor is ever-growing with the increase of cure rate. The survivors′ outcome has aroused more and more attentions from medical personnel. ICU survivors tend to experience lasting physical, psychological and cognitive injuries, the post-traumatic stress disorder is one kind of significant psychological injury associated with patients′ critical experience. This review aims to summarize relevant literatures, introduces the prevalence, risk factors, complications, and interventions of ICU survivors′ post-traumatic stress disorder symptom, in order to prevent ICU survivors from post-ICU psychological injury and improve their long-term outcome.

Objective To investigate the clinical characteristics and treatments of endometrioid carcinoma patients with preoperative diagnosis of endometrial hyperplasia.Methods From 2005 to 2010, 404 patients were diagnosed with endometrioid carcinoma after hysterectomy.Among these patients,44 of them were diagnosed atypical endometrial hyperplasia(AEH) preoperatively.Retrospectively analysis the characteristics of these patients with SPSS13.0.Results Among the 44 cases, all of them were grade G1 disease, and 39 of them received comprehensive staging surgery.14(32%)young cases preserved bilateral ovaries.9 cases(20%) were given adjuvant radiology.No recurrence was detected during the median follow up of 52 months.Compared to the premenstrual group, although no statistical difference was detected, more patients with risk factors of deep myometrium invasion(4/22 vs 1/22) and lymph-vascular space invasion(LVSI, 3/22 vs 0/22) in the postmenstrual group.Compared to the patients who diagnosed with endometrioid cancer(EC) preoperatively, there are more patients with grade G1(P=0.000), fewer patients received adjuvant chemotherapy(P=0.003) and fewer recurrence(P=0.019) in AEH group.Conclusions The endomtrioid cancer patients who diagnosed with atypical hyperplasia preoperatively have better prognosis.Hysterectomy with bilateral ovaries preserved is acceptable in young patients.Post menopause patients have more risk factors of deep myometrium invasion and LVSI.

Objective To evaluate whether susceptibility weighted imaging (SWI) can be used in definition of penumbra during acute stage of cerebral infarction,compared with perfusion weighted imaging (PWI).Methods Ischemic stroke patients within 3 days after onset were included.They adopted multimodal magnetic resonance imaging examination,including regular magnetic resonance imaging sequence (T1 WI,T2 WI and T2-weight fast fluid-attenuated inversion-recovery),diffusion weighted imaging (DWI),PWI and SWI.Alberta Stroke Programme Early CT Score was done on DWI,SWI and PWI.The mismatch of SWI-DWI (minimal indensity projection (mIP)-DWI) was compared with that of PWI-DWI (mean transit time (MTT)-DWI) and analyzed statistically.The application of prominent vein (PV) on SWI as a sort of alternation of cerebral blood volume (CBV) and direct observation of thrombosis in arteries on SWI were done.Results The SWI-DWI (2.39 ± 1.42) and the MTT-DWI (2.72 ± 1.49) mismatch showed no statistically significant difference (r =0.726,P ＞ 0.05).The grade of PV was positively related with the CBV of the ipsilateral brain tissue on admission (r =0.564,P ＜ 0.05).SWI showed the similar ability with magnetic resonance angiography to judge responsible blood vessels with susceptibility vessel sign.Conclusion SWI-DWI can evaluate the ischemic penumbra.PV may reflect the increased blood volume of the lesion side of the brain tissue.SWI can reveal the thrombosis of the responsible vessels.

Objective To analyze the operative effect of fracture of ulna coronoid process and evalu- ate the repairing effect of reconstruction of combined injury of ligamental structure or radius head.Methods During 2001 to 2004,16 cases(14 males and 2 females)of fractures of ulna coronoid process,aged 18-54 years(mean 36.6 years),were treated operatively in our department.Routine medial approach on the elbow or anterior trance-joint approach was used.Once reduction was achieved,screws or Kirschner wires were used to fix the fracture and the capsule was repaired at the same time.If there was combined fracture of the radius head or rupture of the collateral ligament,simultaneous repair or resection was applied.Functional exercise was requested in all patients.Results The follow-up was 8 to 24 months.Fracture union needed 4 to 6 weeks. Average Mayo elbow score was 80.Conclusion Ulna coronoid process fractures need active therapy. The radius head should be reserved as complete as possible during treatment.It is necessary to work out a standard management plan,and a notice should be taken to ligamental structure examination.
