Objective To study clinical characteristics of bacterial pneumonia with normal procalcitonin (PCT) and C-reactive protein (CRP) in infants and toddlers. Methods Retrospective analysis of clinical data of infants and toddlers with bacterial pneumonia was performed from January 1, 2013 to March 30, 2015. Of them, there were 92 cases with normal PCT and CRP (case groupe) and 95 cases with signiifcantly higher PCT and CRP (control group). Results The median age was 9.25 months in the case group, which was signiifcantly younger than that in the control group (16.55 months) (P<0.05). The median of the course before admission was 5.17 days in the case group, which was signiifcantly longer than that in the control group (3.5 days) (P<0.05). The proportions of fever, dyspnea, and hypoxemia were signiifcantly lower in the case group than those in the control group (P<0.05). Administration of antibiotics before admission was found in 83.69%of cases in the cases group, which was higher than that in the control group (P<0.05). The most common pathogens in the case group was Haemophilus inlfuenza, while Streptococcus pneumonia was the most common in the control group. Conclusion The possibility of bacterial infection cannot be ruled out in pneumonia with normal CRP and PCT in infants and toddlers.

At the urgent request of Artemisia annua (ART) planting, the paper gets artemisinin content (ARTC) of ART in China from literatures. The paper analyses the relationships between ARTC and ecological factors by statistical analytical methods. The paper also analyses the climate suitable rank distribution of ARTC in China by ArcGIS. The results display that first, ARTC is significantly different in China, that ART from the south regions ARTC is higher. Greatest north parts of China have not suitable climate for the growing of ART and the ARTC is lower than 0.2%, when ART grows above the 34th degree of northern latitude. ARTC is higher and ART grows well, when ART grows under the 34 degrees N and grows at the areas between 100 degrees E and 120 degrees E. Second, subtropical zone is the best suitable climate zone for the growing of ART. ART grows well and ARTC is higher than 0.5%, when ART grows in the subtropical zone. Third, temperature, sunshine duration and rainfall are the main ecological factors that affect the growth of ART and the accumulation of ARTC. That the year temperature between 13.9 degrees C and 22 degrees C, sunshine duration between 853 h and 1507 h, rainfall between 814 mm and 1518 mm, is the best climate for the accumulation of ARTC. Temperature between 13 degrees C and 29 degrees C, rainfall between 600 mm and 1300 mm is the best climate for the growth of ART. Fourth, in northwest of Guangxi, eastern of Sichuan, Guizhou and Yunnan provinces, south Chongqing and west Hunan Province, there are suitable climate for the growth of Artemisia and for the accumulating of ARTC. There are also some suitable climate areas for the growing of artemisia in the south of Hubei, Anhui and Jiangsu provinces.

Objective To evaluate the importance of factors affecting efficiency of image display quality of realtime three-dimensional echocardiography (RT-3DE) and establish an optimized method for RT-3DE examination and image processing in children. Methods Based on corresponding cardiac acoustic characteristics in children, 87 healthy children (46 boys, 41 girls, mean 36.2 ± 44.2 months) were selected. Three aspects of seven factors were selected, including acquisition windows, gain, compress, post process, smoothing, frequency fusion and 3D vision for RT-3DE examination and analysis using orthogonal test design method. The principal effectiveness analysis of orthngonal test design method and its table L_(18)3~7 were used. The efficiency rate of 3D image display quality was used as the inspection index for orthogonal test. Results According to the average deviation orders of the seven factors, the maximal average deviation was gain. The aspects with maximal average deviation of each factor were at via-subcostal and via-apical acoustic windows, 90 of gain, 60 of compress, E of post process, 5 of smoothing, F3 of frequency fusion and A to B of 3D vision, respectively. Conclusions The optimized method for RT-3DE examination and image processing could be achieved by setting acquisition windows, gain, compress, post process, etc. It is helpful to promote clinical application of RT-3DE and benefits the design of multi-parameter presetting of ultrasound system to optimize RT-3DE examination in children.

Purpose To evaluate features of the left ventricular twist in patients with atrial septal defect (ASD) using speckle tracking imaging (STI) in order to guide clinical application.Materials and Methods Fifty-eight patients with ASD confirmed by ardiac ultrasound in Shanghai Children's Medical Center from October 2015 to January 2016 were enrolled in this study as case group,which were further divided into group ASD-A with 30 cases and group ASD-B with 28 cases according to the volume of right ventricular.The volume of right ventricular was significantly increased in the group ASD-A,but the volume of right ventricular was not significantly increased in the group ASD-B.At the same time,30 normal children with matched age and sex were chosen as control group.The parameters of left ventricular twist motion in each group were measured and compared by using STI.Results In group ASD-A,The basal and apical part of 6 children rotated counterclockwise.Compared with those in the control group,the basal rotation angle and apical rotation angle of left ventricular in group ASD-A were significantly higher (P＜0.01),and the peak twist and torison of left ventricular in group ASD-A were also higher (P＜0.05).Compared with those in the control group,only the apical rotation angle in group ASD-B was higher (P＜0.05),but the rest parameters of the left ventricular twist motion in group ASD-B were not statistically significantly higher (P＞0.05).Conclusion The significant increase in the volume of right heart load in ASD impacts on the basal and apical rotation of left ventricular.

Objective To determine the feasibility and accuracy of velocity propagation within main pulmonary artery(VP)from color M-mode Doppler imaging using custom software on a personal computer for noninvasive estimation of PVR.Methods Color M-mode imaging of pulmonary flow was obtained and then transferred to computer,the velocity propagation of pulmonary flow was automatically obtained.Comparative studies among Doppler echocardiography,personal computer and cardiac catheterization for predicting PVR had been done in 20 children with congenital heart disease and 20 normal children.Results Velocity propagations of children with congenital heart disease were significant lower than those of normal children obtained by color Mmode echocardiography[(38.38±18.89)cm/s VS(80.34±15.65)cms,P＜0.01),and correlated well with invasive PVR measurements(r=-0.69,P＜0.01).The correlation and repeatability of VP obtained by the custom software were better than VP obtained by Doppler echocardiography(r=-0.78,P＜0.01).A VP cutoff value obtained by the custom software of 35.910 had a sensitivity of 92.9% and a specificity of 100% to within pulmonary artery obtained by color M-mode echocardiography using custom software on a personal computer.

Objective To reveal the character of tricuspid valve in hypoplastic right ventricular heart syndrome (HPRVHS) using 3-dimensional echocardiography(3DE). Methods Twenty eight patients with HPRVHS were included in the study, and they were divided into two groups according the degree of tricuspid regurgitation. Eighteen normal children were included as the control. Volume of right ventricle(VRV), area of tricuspid annulus(TVA),proportion of the leaflets and the distance from tips of leaflets to the nearest papillary muscle were measured with 3DE. These data was standardized by body surface area. Results The volume of right ventricle in HPRVHS was significantly less than that in normal group. The area of tricuspid annulus was significantly correlated with volume of right ventricle(r = 0. 90, P < 0. 0001). In the tricuspid regurgitation group, the proportion of area of anterior leaflet to area of tricuspid annulus was significantly higher than non-regurgitation group and normal group(P <0. 0001). Respectively,the proportion of the area of posterior leaflet to the area of tricuspid annulus in regurgitation group was significantly less than normal and non-regurgitation group. The distance from tips of leaflets was significantly shorter in HPRVHS than in normal group. Furthermore, the distance from the tip of septal leaflet to the nearest papillary muscle was shorter in regurgitation group than non-regurgitation group ( P = 0. 0023). Conclusions 3DE could be applied for evaluating the pathologic change of tricuspid valve in congenital heart disease. In HPRVHS, hypoplastic of posterior leaflet and shortness of the cords of septal leaflet could be the cause of tricuspid regurgitation.
