Objective To evaluate the diagnostic value of tissue Doppler imaging (TDI) in classification of fetal arrhythmias, and conclude characters of each type of arrhythmias by analyzing wave forms of TDI. Methods Fifty-five fetuses suffered arrhythmia were included in study group. By comparing the results with control standard(M and PW), the sensitivity, specificity and reliability of TDI in diagnosis of fetal arrhythmias was calculated. At last, the character of waves by TDI of each type of arrhythmia was concluded. Fetal kinetocardiogram was made to identify the origin of arrhythmias. All cases were asked to perform electrocardiography and echocardiography examination after birth. Results The sensitivity, specificity and reliability of TDI was 98%, 100% and 100%, respectively. The character of atrioventricular waves and kinetocardiogram of 8 types fetal arrhythmias were conclude. Conclusions TDI has great value in classification of fetal arrhythmias.

Objective To provide basis for routine fetal cardiac screening by comparing the ultrasound detection rate of fetal heart defects between the high-risk and low-risk population.Methods According to the questionnaire about maternal risk factors,all 7165 pregnant women were divided into two groups.The high-risk group included 2147 cases and the remained 5018 were considered as low-risk population.Routine fetal heart screening was performed by the four-chamber view,left and right outflow tract views.If some cardiac malformations were found,the detailed fetal echocardiography would be performed.Both the detection rate of fetal cardiac defects and distribution of the relevant risk factors were analyzed.Results Ninty-five(1.33%)cases of congenital heart disease were found in our study,32(1.49%)cases from highrisk group and 63(1.26%)cases from low-risk group.No significant was found between the two groups (X2=0.635,P＞0.05).Karyotyping were performed prenatally in 23 of 95 fetal congenital defects cases by cordocentesis and chorionbiopsy,and 11(47.83%)cases of concomitant chromosomal abnormality were found.Conclusions Routine fetal screening for congenital fetal diseases should be performed in non-selected population for the similar detection rate of fetal defect in high-risk and low-risk group.

Objective To explore the efficacy and safety of recombinant human brain natriuretic peptide (rhBNP) in the patients with severe heart failure (HF). Methods A prospective multicenter study was conducted. Patients whose age > 18 years old, and with the New York Heart Association (NYHA) cardiac function grade overⅢ - Ⅳ , acute cardiac insufficiency and the acute exacerbation of chronic cardiac insufficiency admitted to intensive care unit/cardiovascular care unit (ICU/CCU) of 58 Hospitals in China were enrolled. On the basis of the conventional treatment, all patients would be given rhBNP (neo adjuvant) with a loading dose of 1.5 μg/kg for 3-5 minutes, and followed by a maintenance dose of 0.010-0.015 μg·kg-1·min-1 for 3-7 days. Before the treatment and 1, 3, 7 days after treatment, researchers detected indexes of cardiac and renal function, the levels of N-terminal B-type natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF), cardiac output (CO), pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), urea nitrogen (BUN), serum creatinine (SCr), and urine output; the renal function index was re-evaluated at 30 days after administration, and the time entering ICU again, re-admission, cardiovascular events were recorded. Results 408 patients were enrolled, with 241 males and 167 females. Age range was 28-95 years, the average age was (63.0±15.8) years, and 50-70 years old accounted for 46.8%. Compared with the data before treatment, NT-proBNP, PCWP and CVP significantly decreased at 6 hours after treatment [NT-proBNP (μg·kg-1·min-1): 4378.58±4082.29 vs. 6403.41±5759.48, PCWP (mmHg, 1 mmHg = 0.133 kPa):12.41±2.21 vs. 14.26±2.85 , CVP (mmHg): 10.63±2.62 vs. 11.45±3.45, all P < 0.05], and with the prolongation of injection, NT-proBNP, PCWP and CVP were gradually declined; CO 1 day after treatment (mL: 4.89±0.81 vs. 4.40±0.92) and LVEF 3 days after treatment (0.465±0.100 vs. 0.431±0.107) were significantly increased (both P < 0.05), and with the prolongation of injection, CO and LVEF were gradually increased. There were no obvious changes in BUN and SCr during the treatment, but 30 days after treatment, SCr was significantly lower than that pre-treatment (μmol/L: 110.98±47.40 vs. 132.62±75.60, P < 0.01). Compared with the data pre-treatment, urine output per hour was significantly increased at 3 hours after treatment (mL: 129.59±82.16 vs. 89.60±53.49, P =0.000); urine output every 24 hours was significantly increased at day 1 and day 2 after administration (mL: 2676.54± 1006.83, 2678.74±975.97 vs. 2150.36±283.76, both P < 0.01). In 7 days, the re-entry ICU rate was 2.7%, and the re-hospitalization rate was 2.88% within 30 days, re-cardiac failure rate was 1.43% in 30 days, and the overall fatality rate was 9.55% in 30 days. Conclusions The rhBNP can significantly improve heart function in patients with HF. And, it has a certain effect on renal function. The rhBNP is effective and safe for the treatment of cardiac insufficiency.

Objective:To explore whether apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin can be cross-presented by dendritic cells(DCs) and enhance immune responses.Methods:DCs were induced from peripheral blood monocytes cells by GM-CSF/IL-4 for 6 d,then they were stimulated with either apoptotic ovarian cancer HO8910 cells,frozen-thawed HO8910 cells or control cells for 4 h.Their surface markers and phagocytotic ability were detected by flow cytometry and confocal microscopic scanning assay,respectively.DCs of different groups were cultured with CD8+ T cells isolated by magnetic cell sorting,and the ability of DCs to activate CD8+ T cells was evaluated by 3H-TdR,the activity of CTL to kill tumor cells was evaluated by LDH.Production of IFN-? by CD8+ T cells was measured by ELISPOT.Results:Apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin could be phagocytized by DCs,which subsequently promoted the maturation and antigen presenting ability of DCs.Apoptotic ovarian cancer cells implused DCs significantly promoted proliferation of CD8+ T cells compared with that of control cells(P

Objectives To investigate the effects of Apelin 13 on myocardial metabolism in diabetic rats.Methods A total of 40 male Wister rats were randomly divided into normal control group (NC,n=8) and experimental group (n =32).Diabetic rats model were induced by high-sugar and high-fat diet combined with low-dose intraperitoneal injection of streptozotocin (STZ).The wellestablished 28 diabetic model rats were randomly divided into diabetic model group (DM,n=14) and apelin-13 treated group (n=14).In the Apelin-13 group,diabetic rats were administered Apelin-13 [0.1 μmol/(kg · d)]by intraperitoneal injection for 10 weeks,while the control group and diabetic model group were given an equal volume of 0.9％ NaCl.At the end of the 10th week,all rats were sacrificed after fasting glucose measurement.Levels of serum free fatty acids (FFA) and myocardial FFA were measured by ELISA.Expression of myocardial glucose transporter member 4 (GLUT4) were detected by immunohistochemistry.The mRNA expressions of myocardial PPARα,CD36 and CPT-1 were detected by real-time fluorescence quantitative PCR.Results Fasting blood glucose,serum FFA and myocardial FFA were significantly higher in DM group than in NC group (all P＜ 0.05).The level of plasma glucose and myocardial FFA were significant lower(P＞0.05) in Apelin-13 treated group than in DM group;but serum FFA was not significantly lower(P＜0.05).The mRNA expressions of PPARα,CD36,CPT-1 in cardiac myocyte were higher in DM group and Apelin-13 treated group than in control(P＜0.05),and lower in Apelin-13 treated group than in DM group(P＜ 0.05).The expression of myocardial GLUT4 was significantly lower in DM group(1.138±0.316)and in Apelin-13-treated group (4.631 ± 1.832) than in NC group(9.132 ± 2.156),(F=65.507,P＜ 0.05),and higher in Apelin-13-treated group than in DM group(P＜0.05).Conclusions Apelin-13 increases myocardial expression of GLUT4,improves utilization of FFA,and it can effectively reduce the expression of PPARα,CD36 and CPT-1.Therefore,it may play a vital role in the improvement of myocardial metabolism in diabetic rats.

Objective To explore the reasons for disharmony between medical staff and medical staff because of electronic clinical ordering,to specificate electronic medical order in ward in order to create a harmonious relationship between doctors and nurses. Methods The methods of qualitative research conducted in-depth interviews of 12 medical staff, field recordings and transcripts, and the method of content analysis were used. Results Two themes were sublimated:medical staff reasons:lack of communication between the medical staff;new doctors didn't have a good command of medical norms of specialist electronic orders; on the responsibility of checking the doctor's advice problems may lead to potential adverse events occurrence. System equipment reason: the electronic doctor's advice system set up the problem; the office computer quantity is insufficient. Conclusions Nonstandard electronic medical management leads to the disharmony of health care. It is suggested to standardize the management of electronic medical advice by implementation of the responsibility to avoid medical coupling errors. The health care workers need to strengthen communication, mutual understanding and forgiveness, in order to create a harmonious medical environment.
