Objective To evaluate the value and clinical application of cardiac structure Z scores in children with preoperative tetralogy of Fallot (TOF) by echocardiography. Methods Considering the result of 31 patients who underwent echocardiography in Shenzhen Children’s Hospital before TOF repair from January 2011 to September 2013, the median age was 10 months (range:3 days to 14 years). Other 31 normal children were selected as normal control group with age-and sex-matched, the median age was 10 months (range: 6 days to 13 years). Echocardiographic measurements included the diameter of right ventricular outflow tract (RVOT), pulmonary valve diameter (PVD), left pulmonary artery diameter (LPAD), right pulmonary artery diameter (RPAD), pulmonary valve peak velocity (PV-Vmax), tricuspid annulus diameter (TVD), mitral annulus diameter (MAD), left ventricular end-diastolic volume (LVEDV) and left ventricular mass (LVmass). Shenzhen Children’s Hospital pediatric echocardiography normal reference values and the regression equation are applied to obtain the forecast average, and using the Z-score formula into the standard value (Z=[M-y]/ MSE ). Results There was no significant difference in body surface area between the TOF group and control group (P>0.05). Compared with control group, the true value of RVOT reduced significantly in TOF group, its Z-score showed negative values increase (-4.87±1.86 vs 0.33±0.93, t=-13.90, P<0.05). PVD, LPAD and RPAD reduced significantly in TOF group, those Z scores showed a negative value increase (-4.15±2.93 vs 0.11±0.85, t=-7.76;-1.35±2.38 vs 0.66±1.17, t=-4.24;-1.47±2.03 vs 0.59±1.04, t=-4.94;all P<0.05). While PV-Vmax increased significantly, and it’s Z score showed a positive value increase (8.38±0.19 vs 0.24±0.98, t=29.50, P<0.05). TVD of TOF patients was slightly larger than the control group (P=0.10), but the Z score was significant greater than the control group (1.00±1.17 vs 0.29±0.52, t=3.06, P<0.05). MV-D, LVEDV and LVmass of TOF patients were slightly decreased than the control group (all P>0.05), but the Z scores of TOF were significantly reduced than the control group (0.25±0.78 vs 0.76±0.65, t=-2.75;-0.92±1.94 vs 0.03±1.01, t=-2.41;-0.83±1.59 vs 0.67±0.69, t=-4.71; all P<0.05). The Z scores of RVOT, PVD, LPAD and RPAD had no significant difference between transannular patch surgery and pulmonary valve-sparing repair patients (-4.89±2.03 vs -4.84±1.67, t=-0.08; -4.73±3.49 vs -3.34±1.75, t=-1.31; -1.88±2.54 vs -0.62±2.00, t=-1.49;-1.89±1.90 vs-0.84±2.15, t=-1.41;all P>0.05). For the Z scores of PV-Vmax, there were no significant difference between transannular patch surgery and pulmonary valve-sparing repair (8.58±1.20 vs 8.12±1.16, t=1.07, P>0.05). Conclusions The Z scores value of cardiac structure can be used in quantitative analysis of RVOT obstruction and development of left ventricular backward of TOF. The Z score of transannular patch surgery is more lower than pulmonary valve-sparing repair patients. The normalized Z score by body surface area correction is important for the preoperative diagnosis and the surgical planning.

Objective To investigate the cognition and behaviors of sun-protection and the facial photoaging in a Nanjing population, and to analyze the relationships between them. Methods The objects being investigated in Nanjing (n=974) were divided into 10 groups according to age. The ordinary information, knowledge and behavior of sun-protection and Glogau photoageing type of face were studied by questionnaires. The results were analyzed by a logistic regression model to select the related factors to photoageing. Results The risk of skin photoageing increased with age. Most of the 46-65 years old crowds were type Ⅲ photoageing. Most of the objects being investigated had some knowledge and active awareness of sun-protection and could use some ways to protect themselves from sun. However, most people did not use the sunscreen correctly. Those who had higher level awareness and knowledge of sunprotection suffered less risk from skin photoageing. Sunbath without sunscreen for a long time outside activity was a high risk factor of development to skin photoageing. Shade, broad-brimmed hat and sun-protection in autumn were the protective factors. Conclusion Active awareness and correct methods could help prevent skin photoageing. In order to avoid the damages to skin from ultraviolet efficiently, the accurate ways of using sunscreens should be well understood.

Objective To screen genes differentially expressed between dermal papilla cells from occipital and vertex scalp of patients with androgenic alopecia (AGA) through a 3D culture system.Methods Dermal papilla cells isolated from the occipital scalp tissue of patients with AGA were cultured in a 2D system for several days.Then,the third-passage dermal papilla cells were subjected to a 3D culture with the presence of dihydrotestosterone (DHT) for 72 hours (experimental group).The dermal papilla cells isolated from the vertex scalp tissue of patients with AGA,which were cultured in a 3D system with dimethyl sulfoxide,but not DHT,served as the control group.Subsequently,total RNA was extracted from the cells and reversely transcribed into cDNA followed by labeling with Cy3 and hybridization to a NimbleGen microarray.Gene ontology (GO) and pathway analysis was carried out to screen differentially expressed genes between the experimental and control group.Real time PCR was conducted to validate the results of microarray analysis.Results As the genome-wide expression profile analysis showed,there were 622 genes differentially expressed between the experimental group and control group,of which,359 were up-regulated and 263 were down-regulated in the experimental group compared with the control group.The above results were corffirmed by real time PCR.GO analysis revealed that the up-regulated genes,such as the CHEK1 and Tobl genes,were mainly involved in the inhibition of cell proliferation and promotion of cell apoptosis,while the down-regulated genes,such as the BAMBI,EFNA3,Dlx3 and UCGC genes,were associated with the acceleration of cell proliferation as well as the growth and development of epidermis.Pathway analysis showed that cell circle-controlling molecules were the most abundant molecules.Conclusions Numerous signalling molecules and pathways are involved in the development of AGA,which are mainly responsible for the modulation of cell circle,proliferation and apoptosis.
