Deletions,insertions,duplications,and complex multi-site variants,now formally termed copy number variations(CNVs),are regions larger than 1 kb that are present with variable copy numbers in comparison with the reference genome.CNVs in humans and other mammals are associated with a series of complex genetic diseases including congenital heart disease.The studies of CNVs have become hot topics.This review mainly discusses the principle of CNVs,the detection techniques and CNVs in the pathogenesis of congenital heart

Medical art are essential in consumer health education,facilitating consumers to un-derstand medical concepts,invisible body parts and complex pathology. This paper reviewed the origin and development medical arts,analyzed the characteristics of medical arts specific for consumers rather than professionals,and discussed the opportunities and challenges of medical arts in internet era.

Digoxin is the most frequently prescribed cardiac glucoside in pediatrics.Owing to its pharmacokinetics profile and narrow therapeutic index,some cases such as digoxin intoxication or dose insufficient are not rare.Recent evidence suggests that age,weight,hepatic and renal function,intestinal microbiome,drug interactions and others have influence on the pharmacokinetics of digoxin.So more attentions should be paid to the influencing factors mentioned above when digoxin concentration is monitored except observing intoxication to ensure rational drug use.

Objective To explore the application of transanal drainage tube in decompression of acute left- sided colorectum obstruction and its nursing. Methods Twenty- one cases of patients, with acute left-sided colorectal obstruction, were enrolled in this study from 2011 and 2014, Results Of the 21 cases, 5 failed to drip, 6 was difficult to drain, 2 having loose stools around the anus, 2 with the tubes out of the anus, and 6 with obstructed tubes during the drainage. Nineteen finally underwent surgery, 16 of which with 1- stage operation, and 13 of the 16 with sufficient lymph node dissection, without stoma leakage. Conclusions Transanal drainage tube plays an important part in acute left- sided colorectal obstruction, and a professional nursing work could help maintain the unobstruction of the tube, which is of much importance in the procedure of the drainage and the decompression of the obstruction.

Objective To observe the influences of Siwu Decoction on perioperative hidden hemorrhage in senile patients with intertrochanteric fractures, and to supply evidence for Chinese medicine in treating the hidden hemorrhage of senile intertrochanteric fractures patients. Methods By following the inclusion and exclusion standard, 36 patients were admitted into the study. With reference to the medication of Chinese medicine, the patients were divided into treatment group and control group. All of the patients were given conventional anti-infection medicine, symptomatic treatment and dietary guidance. In addition, the treatment group took Siwu Decoction orally, 10 days constituting a period of treatment from the third day after surgery. Before and after treatment, we observed hemoglobin (Hb) level, hematocrit (Hct) and hidden blood loss (intraoperative and postoperative) . Results Hb level was increased and hidden blood loss was decreased in the treatment group ( P<0.05 compared with those before treatment) , but the changes were not obvious in the control group (P>0.05) . The improvement of Hb level and hidden blood loss in the treatment group was superior to that in the control group (P<0.05) . Conclusion Siwu De-coction can increase Hb and Hct levels in senile patients with intertrochanteric fractures, which results into the im-provement of perioperative hidden blood hemorrhage to some extent.

Objective: To investigate the understanding of other' s mind in children with autism in Beijing.Method: The instrument of this study was experimental test story. Results: Children with autism could understand other person' s physical and social desire, and predict behavior of others in accordance with desires. They basically unerstood other' s positive and negative emotions. However, they had a special difficult in understanding other' s cognitive mental states such as false belief. Concluslon: It indicated that the development of understanding other' s mental state is much more gradual and complex. Understandding other' s false belief is not all or nothing. The difference in understanding other's false belief between children with autism is not absolute, but relative.

The present situation of data acquisition of principal diagnosis on front page were introduced and analyzed,the importance of selection and filling out the principal diagnosis on from page were expounded.Meanwhile,how to select the principal diagnosis correctly,clear and definite the definition of Principal Diagnosis,rule of selection of principal diagnosis were also introduced.Besides,some experience on how to select the principal diagnosis were presented.All of these,that analyzing the present situation and the problems of principal diagnosis,in order to assisting medical staff to select principal diagnosis correctly.

Objective To control the quality of Huoxue Quyu syrup,the content of Ferulic acid was determined by RP -HPLC.Methods Ferulic acid was separated on C18column.Methanol -water -acetic acid(40∶60∶2)was used as mobile phase and the detecting wavelength at 322nm.Results The linearity of Ferulic acid was in t he range of 10～40?g?mL -1 (r =0.9997,n=5);the average recovery was 99.52%with RSD being 0.58%(n=5).Conclusion The method is simple and rapid and can be used for controlling the quality o f Huoxue Quyu syrup.

Childhood asthma and obesity are significant public health problems all over the world.In the past decades,the prevalence of both diseases has increased considerably.Because both asthma and obesity appear to have their beginnings in early childhood,common exposures that predispose individuals to both conditions may explain how they are associated.These exposures include common genetic predictors,prenatal exposure to specific nutrients and overall maternal nutrition, colonization patterns of the neonatal and infant gut,birth weight and infant weight gain,and sedentary behaviors in early life.

Acromegaly is usually caused by excessive secretion of growth hormone(GH) for a prolonged period from a pituitary adenoma along with increased levels of insulin-like growth factor-1(IGF-1), which leads to acral and soft tissue enlargement and metabolic dysfunction, such as cardiovascular system or glucose metabolism. Its features are elevated plasma GH/IGF-1 concentrations, however the biochemical tests remain challenging.
