Chinese Journal of Interventional Cardiology 2014;(9):563-566
Objective To investigate the risk factors for heart failure in pregnant women with heart disease. Methods A retrospective analysis was made from 340 cases of pregnant women with heart disease in our hospital from January 2008 to December 2013. The pregnant women who presented heart failure were categorized in the observation group (n=65), and others were in the control group (n=275). Data was used to analyze by univariate and multivariate logistic regression for heart failure in pregnant women with heart disease. Results The total 340 cases of heart disease included 132(38.8%) of congenital heart disease, 86(25.3%) of rheumatic heart disease, 63(18.5%) of arrhythmia, 33(9.7%) of hypertensive heart disease and 26(7.6%) of peripartum cardiomyopathy. 65 cases (65/340, 19.1%) presented with heart failure, there were 4 cases resulted in death (1.2%). Multivariate logistic regression analysis showed that age≥35, the baseline parameters of New York Heart Academy (NYHA)≥Ⅱ, pulmonary artery pressure>50 mmHg (1 mmHg=0.133 kPa), baseline heart rate>100 bpm, cardiac events occurred before pregnancy were the independent risk factors for heart failure. Prenatal counseling and antenatal examination were the protective factors for heart failure. Conclusions There are a variety of influencing factors for the heart failure in pregnant women with heart disease. It is necessary to take targeted intervention measures in response to the influencing factors so as to reduce the development of heart failure.

Four fresh corpses of infant are used in this research. Three-dimensional microvasculatures of the sinoatrial node and atrioventricular node were studied by means of the observation of vascular casts with SEM. The results showed that the vascular bed of the sinoatrial node was consisted of the microvascular networks. It was oval in shape. The central artery penetrated this node, through its longitudinal axis and divided progressively into arterioles and precapillary arterioles and finally, they branched into capillary networks at the superficial part of the node. The postcapillary venules were characterized by draining blood in accordance with area. The microvascular construction of atrioventricular node was an oblate microvascular network in shape. There was a layer of delicate capillary networks at its superficial part. In the depth of the capillary networks, the venous plexus which was thick and sinusoidal in shape was observed through the meshes. The artery of atrioventricular node entered the node from one side of it. In the node, the artery ramified by degrees to periphery into precapillary arterioles, which penetrated venous plexus and connected with capillary networks in the superficial part of the node. There were evidently narrow rings, whick were impression of the muscle sphincters at the origin of thep ostcapillary venules.

Shenfukang is an effective formula for glomerulonephritis applied in the first affiliated hospital of Guangzhou University of TCM. It is composed of Radix Folium seu Flos Tripterygii wilfordii, Radix Astragali seu Hedysari, Radix Notoginseng, Herba Leonuri, etc.. Glomerulonephritis rat model was induced by cationized bovine serum albumin (C-BSA) according to Border's method and was used to observe the pharmacological action of Shenfukang. The results showed that Shenfukang can eliminate urine protein, increase the levels of serum protein, albumin (A), globulin (G) and A/G ratio, and decrease the contents of serum cholesterol, creatinine and urea nitrogen. It can also counteract the increase of plasma TXB 2 and the decrease of plasma 6-keto-PGF 1? . LD 50 of Shenfukang for mice is 174.34?36.74?g/kg which is much larger than that of Tripterygium wilfordii (29.73?6.46?g/kg for female mice and 101.74?10.93?g/kg for male mice). It is indicated that Shenfukang exerts a protective effect on renal function and reduces toxicity of Tripterygium wilfordii.

Objective To enhance the awareness of diagnose and treatment of venous thrombus in premature infants. MethodsThe clinical features, treatment and prognosis of lower limb vein thrombus in three case of premature infants were retrospectively analyzed.ResultsThree premature infants of gestational age 29-36 weeks were found thrombosis in 1-57 days after birth. One case received peripherally inserted central cathete (PICC). All of three cases had infection signs and trauma. One case received thrombolytic and anticoagulant therapy, one case received high dose thrombolytic therapy, and both of them were treated successfully without bleeding complication. However, another case was deteriorated after giving up treatment.ConclusionsCritically ill premature infants are at high risk of thrombosis. Infection, indwelling tube, thrombophilia constitution, and maternal risk factors were the high risk factors of thrombosis. Early detection, early diagnosis, and effective individualized treatment can improve the prognosis.

Objective To demonstrate the histology in acellular dermal matrix(ADM)after being transplanted in vivo over time. Methods Forty male SD rats were recruited for the experiment. Subcutaneous implantation of an 1 cm × 1 cm ADM was given in the left sides on the back of the rat for the experimental group, while only dissection and suturing were performed in right side of the back for the control group. All the animals will be sacrificed at appointed time after operation, Five ADM samples were harvested in each time point. The content and proportion of collagen type were examined with HE staining, Picrosirius staining, Masson′s trichrome staining, and Immunohistochemical staining (targets: pan macrophage, M1 macrophage and M2 macrophage). Results All rats survived after operative without any complications. Significant differences of thickness were not observed at the end of 5 months; HE scores suggested that ADM increased in cell infiltration scores in 2 weeks before the plateau , vascularity also showed a similar trend; Collagen trichrome staining showed a substantial increase in density of collagen bundles with time. The comparison of the proportion of collagen among days showed significant differences (P < 0.05). Immunohistochemical staining of M1 and M2 showed that macrophages had distinct polarization profiles in materials. Furthermore, the comparison of M1 vs M2 response associated with different materials showed significant differences in all time points (P < 0.05). Conclusions The chemically cross-linked ADM could keep long time in the body; ADM significantly stimulated proinflammatory of M2 differentiation from M1 in constructive remodeling.
