Purpose:To study the value of high frequency color doppler ultrasound diagnosis for breast intraductal papilloma.Methods:50 patients with breast intraductal papilloma,all confirmed by surgical and pathology,and examined by ultrasound before surgery,all had symptoms of excreting blood or liquid from nipple or palpable mass. The probe were placed on the surface of the breast to scan radially from nipple,after finding the enlarged duct,try to detect the neoplasm in it carefully. The two dimensional images were observed and the color Doppler flow codes were detected.Results:The detection rate and the diagnostic accuracy rate of breast intraductal papilloma by ultrasound are 62.0% and 38.0% respectively,ultrasonography is better than mammography and near infrared light scanning.The images were divided into four types:one type of no unusual finding(7 cases),one type of finding both the enlarged duct and the tumor(19 cases),one type of finding the enlarged duct only(12 cases),one type of finding the tumor only(12 cases),the images of the type of finding both the enlarged duct and the tumor are typical. The detection rate of flow by color doppler ultrasound is low(5/50).Conclusions:The high frequency color doppler ultrasound is valuable in diagnosis of breast intraductal papilloma,and the special symptom ,the accurate detection method and the typical images are the key of ultrasound diagnosis.

Tort Liability Law set tougher requirements on the validity and authenticity of medical records,featuring explicit protection of patient rights of informed consent.Based on the changes in the law since its enforcement,the authors studied existing deficiencies of electronic medical records and came up with the following suggestions.Establish sound legal accreditation system for electronic medical records; perfect related laws and regulations to ensure standard application of the electronic medical records; and work out regulations to make medical staff aware of their legal responsibilities when applying electronic medical records.These recommendations will enable electronic medical records better fit the current legal environment onto the track of healthier development.

Objective To study the neuroprotective role of TFP5 in a MPTP-induced mouse model of Parkinson's disease (PD).Methods C57BL/6 mice were used as experimental animals.Briefly, 5 consecutive days of intraperitoneal injection of 25 mg/Kg 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was applied to induce mouse PD model.The mice were randomized into 5 groups including control group,model group, scrambled TFP5 peptide (Scb) group, TFP5 group and roscovitine group.On the 7th day after the first injection of MPTP,behavior tests were performed, and then western blot method was employed to detect the expression of p25 and phosphorylated MEF2D in substantia nigra.Tyrosine hydroxylase (TH) immunohistochemical staining was performed to observe the apoptosis of dopaminergic neurons in substantia nigra pars compacta (SNpc) 28 days after the first injection of MPTP.Results MPTP increased the expression of p25 (0.48±0.10 vs 0.26±0.02, P<0.05) and phosphorylated MEF2D (0.81±0.10 vs 0.22±0.02, P<0.05) in substantia nigra, but decreased the number of dopaminergic neurons in SNpc (348.67±24.40 vs 463.29± 19.61, P<0.05),resulting in motor impairment in the model mice (P<0.05).Intraperitoneal injection of 30mg/Kg of TFP5 for 3 days effectively reduced the excessive phosphorylation of MEF2D (0.25 ± 0.12 vs 0.81 ± 0.10, P< 0.05) in substantia nigra, rescued dopaminergic neuron reduction of SNpc (422.92±8.41 vs 348.67±24.40, P<0.05), and improved the motor ability of the model mice (P <0.05).Roscovitine exerted almost same neuroprotective role as TFP5 ,while Scb had no protective effect.Conclusion TFP5 can rescue MPTP-induced damage of dopaminergic neurons in substantia nigra, and thus improve motor impairment of model mice,which may be mediated by the inhibition of Cdk5/p25 activity.

Objective To evaluate the effects of dietary intervention with low glycemic index (LGI) and low glycemic load (LGL) on dietary knowledge and dietary modification of patients with type 2 diabetes mellitus (T2DM).Methods This study was a cluster randomized controlled study.From June to September 2010,105 T2DM patients were randomly sampled from 3 residential areas (n =35 in each) in Jin Pen Ling community,Changsha,Hunan province and divided into three groups with a random number table:whole-day dietary intervention group (group A,n =35),breakfast dietary intervention group (group B,n =35),and control group (group C,n =35).Interventions included 3-month health education and dietary intervention.Dietary knowledge,dietary oils,glycemic index (GI),and glycemic load (GL) of the three groups were compared before and after intervention.Results Before intervention,all the three groups showed a low level of knowledge about GI (57.7 %),and high levels of average GI value of each meal (69.71 ± 8.55),GL value per day (132.45 ± 16.25),and daily cooking oil intake [(39.95 ± 20.64)g].The average knowledge level about GI increased after intervention in both group A (96.3% vs.57.1%,P <0.05) and group B (94.5% vs.60.5%,P<0.05),but not in group C (54.8% vs.55.3%,P>0.05).The reduction of daily cooking oilintake in group A was larger than those in group B and group C [(7.81 ± 3.91) g vs.(-5.12 ± 1.37) g,(7.81 ± 3.91) g vs.(-3.45 ± 5.95) g,both P < 0.05];so was the average GI value of each meal [group A,(5.95±2.27);groupB (-0.85±1.87);groupC,(-2.87±1.93);allP<0.05].The changes of GL values in group A (11.31 ±4.31) was better than in group B (1.23 ±27.82) and group C (-0.43 ± 18.40)(both P <0.05).Conclusions The average GI value,GL value,and daily cooking oil intake of T2DM patients were all at a high level before intervention,while the level of knowledge about GI was at a low level.Health education providing GI knowledge may effectively improve the knowledge about GI in T2DM patients,while LGI and LGL dietary intervention may promote diet modification.Whole-day dietary intervention may be more effective than breakfast intervention.

One hundred and seventy six consecutive patients with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator ( rt-PA ) in 4.5 hours from symptom onset during February 2009 to July 2013 were included in the study.Modified Rankin Scale was used to evaluate the recovery of neurological functions.Patients were divided into good ( 0 -1 ) or poor ( 2 -6 ) outcome groups according modified Rankin Scale score.Univariate analysis and multivariate logistic regression analysis were used to determine the differences of clinical data between the two groups.The age of patients with good outcome was significantly lower than that of poor outcome group [ ( 61.4 ±11.5 ) vs.( 69.0 ± 13.2) years,P =0.000].Compared to patients with poor outcomes, patients with good outcome group showed lower rate of diabetes [ 13%( 12/93 ) vs.29%( 24/83 ) , P =0.009 ] , lower blood glucose level [(5.05 ±0.97) vs.(5.83 ±1.72) mmol/L,P=0.020], higher uric acid level[(404.4 ±151.7) vs.(345.6 ±107.5) μmol/L,P=0.028],shorter onset to treatment time [(1.92 ±0.94) vs.(2.30 ±1.01) h, P=0.019],lower baseline National Institute of Health Stroke Scale score [(14.0 ±5.2) vs.(16.0 ± 6.2),P=0.025],lower systolic blood pressure level at 2 h[(140.8 ±18.3) vs.(149.0 ±18.9) mmHg (1 mmHg=0.133 kPa),P=0.005]and 24 h [(137.6 ±21.9) vs.(147.1 ±17.4) mmHg,P=0.009] after thrombolysis.Logistic regression analysis showed that uric acid levels were not related to hemorrhagic transformation independently (P =0.172,OR =0.965,95%CI:0.917 -1.016), but were related to outcome independently (P=0.047,OR=0.957,95%CI:0.916-0.999).
