Objective To investigate the feasibility and accuracy of velocity vector imaging(VVI)to assess strain and strain rate of right ventrieule(RV)during varying myocardial functional states.Methods VVI of the longitudinal RV were recorded in 7 closed-chest anesthetized mongrel dogs from the apical 4-chamber view during 3 different inotropic states.Peak dp/dt from the RV contraction during the right cardiac catheterization,which was used as the gold standard of RV contractility,was obtained simultaneously in each inotropic state.Peak systolic velocities(V), peak systolic strain rates(SR),peak systolic strains(S)at the basal, middle and apical segments of RV free wall and septal from the longitudinal axis were quantitatively measured by using VVI software system respectively.Results The peak systolic strain and strain rate of the longitudinal RV free wall and septal were increased with the infusion of dobutamine and decreased with the infusion of metoprolol.A significant correlation was found between peak RV dp/dt and RV mean strain and mean strain rate(r=0.79, 0.75;P <0.01).Among all RV segments, the peak systolic S,SR of RV basal free wall had the most significant correlation to peak dp/dt (r=0.83,0.78;P<0.01).Conclusions Strain rate imaging drived from VVI could quantitatively and sensitively detect the longitudinal RV contractile function.Peak systolic S and SR determined at the longitudinal RV basal free wall were the strong noninvasive indices of RV contractility.

Objective To understand use of blood pressure-lowering medications and to identify factors contributing to their compliance among hypertensive patients at a community health-care service center under Huairou County Hospital, Beijing to improve community management for hypertensive therapy.Methods Medical records of hypertensive patients who visited Qiaozizhen community health-care service center in Huairou county, Beijing during June 2008 to May 2009 were analyzed and 849 of them were interviewed using a pre-tested, structured questionnaire with most closed ended questions included to understand their use of anti-hypertensive drugs and its related factors. Results In 849 hypertensive patients under community management, 78.92% percent (670/849) took anti-hypertensive drugs, 72.54%percent (486/670) in good compliance with drug treatment, and 29. 63 percent (144/486) under guidance of their general practitioners or visited secondary-care hospitals or above, 62. 14 percent (302/486) took drugs by themselves and 8. 23 percent (40/486) took drugs following advice by their relatives or other hypertensive patients. The most common used drugs in 503 hypertensive patients who could remember names of the drugs included reserpine compound tablets, reserpine and triamterene compound tablets (302/503, 60. 04% ) and calcium-channel blockers ( 181/503,35.98% ). Overall, blood pressure was under control in ( 289/849,34. 04% ) percent of those with community management, and( 189/486, 38. 89% ) percent of them kept in a good compliance, significantly higher than that in those with poor compliance (48/179,26. 82% ) (P =0. 0032). Results of multivariate logistic regression analysis showed that drug compliance associated mainly with complications of hypertension ( OR of 4. 423 and 95% CI of ORs 2. 141 - 9. 137). Conclusions Drug compliance among hypertensive patients is still poor in rural Beijing, most with reserpine compound tablets.It is necessary to pay more attention to health education among hypertensive patients, particularly about when to start drug-taking and how to take drugs in a scientific way-regularly and complying with physicians'prescription.

Objective To determine the prognosis and risk factors of neonatal cerebral infarction.Methods From January 2002 to December 2010,44 newborn infants were diagnosed with cerebral infarction by imaging examinations at Peking University First Hospital.The neurodevelopmental outcomes of these newborn infants were followed up and evaluated by clinical manifestations,Gesell development scale,cranial imaging,electroencephalogram and auditory evoked potential.Factors related to prognosis were analyzed with single and multi-factor Logistic regression analysis.Results Thirty-eight (86%) cases were followed up,and of these cases,five children died and the results of three were inconclusive due to small age (less than 6 months old).Among the remaining 30 children,neurodevelopmental outcome was normal in 15 cases and abnormal in the remaining 15 cases,thus,the incidence of sequelae was 50% (15/30) and the mortality rate was 13% (5/38).Of the 15 abnormal cases,all had cerebral palsy and movement retardation,eight cases had cognitive impairment,eight cases had epilepsy and five had visual impairment.The incidence of large cerebral infarction (more than one lobe) was 14/15,worse cranial imaging outcome (one month after treatment,cerebral infarction lesion still present or had expanded)was 13/15,and severe complications was 8/15 in the newborns with sequelae,which were higher than in those without sequelae (4/15,5/15 and 1/15,respectively) (x2=13.889,8.889 and 7.778,all P<0.05).Logistic regression analysis showed that large cerebral infarction was a risk factor for sequelae (OR=38.500,95%C1:3.749-395.407,P=0.002),however,worse cranial imaging outcome (OR=8.563,95%CI:0.909-80.683,P=0.061) and severe complications (OR=18.024,95%CI:0.516-630.163,P=0.111) were not risk factors for sequelae.Cerebral infarction with middle cerebral artery injury had a high risk of movement retardation (OR=6.000,95%CI:1.172-3.725,P=0.025),and those with a large cerebral infarction were more likely to have epilepsy (x2=7.273,P=0.010).The incidence of large cerebral infarction in the newborn infants with cognitive impairment was 8/8,which was much higher than in those without cognitive impairment (46%,10/22),thus,infarct area may be related to cognitive ability (x2=7.273,P=0.010).Conclusions Neonatal cerebral infarction might result in many types of sequelae,with motor impairment being the most common form.A large cerebral infarction is more likely to result in abnormal neurodevelopmental outcome.

Diffuse large B-cell lymphoma (DLBCL) is characterized by heterogeneity with respect to morphology, immune phenotype, molecular pathogenesis, clinical presentation and prognosis. With the development of genome and transcriptome sequencing, DLBCL was classified as four subtypes (EZB, BN2, MCD, and N1) or five subtypes (C1-C5). The new molecular pathological typing has a deeper understanding of DLBCL from the levels of genes and molecules which makes the judgment of prognosis more accurate and specific, and it is conducive to the clinical screening of more accurate targeted therapy.
