Coarctation of aorta is a discrete narrowness of the aorta and most commonly occurs in the isthmus.It is a common congenital cardiovascular malformation with morbidity of 5％ ～ 8％ among all congenital heart defects.Coarctation can result in the increase of upper limb blood pressure,the decrease of limb blood pressure,and a decline in cardiac function.Treatments include surgical repair and percutaneous interventions with different complications.Long-term complications and heart functions are important indices for evaluating prognosis and should be closely evaluated postoperatively.This review focuses on progresses of therapy methods,postoperative complications and cardiac function.

Objective To explore the spatial distribution of Keshan disease(KD) in the 15 surveillance provinces(municipalities,autonomous regions ) and to provide the basis for the development of prevention and control strategies.MethodsBased on the KD surveillance data of the 15 provinces in 2007,five indicators were selected.Moreover,a comprehensive indicator score to assess KD of different areas was made through the method of principle components analysis,which was applied for regionalization of the KD areas by the subsection method of standard deviation in whole China.The KD areas were divided into mild,moderate and severe endemic areas.The spatial distribution feature of the comprehensive indicator score was displayed by using geographic information system (GIS).ResultsThe three principal components contained 88.123％ information of all the selected indicators,the first principal component had a close relationship with total KD detection rate,chronic KD detection rate and latent KD detection rate; the second principal component had a close relationship with the threatened number in KD areas,and the third principal component had a close relationship with new KD detection rate; the comprehensive indicator indicates that Gansu,Jilin,Heilongjiang,Hebei,and Liaoning provinces were serious prevalent KD areas; Inner Mongolia,Shandong,Hubei,Sichuang provinces (autonomous region) were moderate prevalent KD areas,and Shanxi,Shaanxi,Yunnan,Henan,Guizhou,Chongqing provinces(municipality)were mild prevalent KD areas.Conclusions The introduction of the GIS to Keshan disease monitoring,provides a convenient and direct method to observe the spatial distribution of the disease,and the results point out the key areas for further KD surveillance according to local conditions.

By using traditional Chinese medicine inheritance support system to analyze the dominant experience and recessive principles of the prescriptions for stranguria in the dictionary of traditional Chinese medicine prescription (DCMP), we aim to define the medication pattern and rule and to acquire new prescriptions. In dominant experience analysis, we were able to find 22 drugs used over 50 times, including drugs of clearing heat, diuresis and relieving stranguria which are the most used and drugs of clearing heat, cooling blood, benefiting Qi and nourishing Yin. In addition, drugs of activating Qi and Xue, eliminating phlegm and removing toxic are often used, including 34 herb pairs and 5 combinations of three-taste drugs are used more than 35 times. These results fully reflect the composition principles and compatibility characteristic of prescriptions for treating stranguria in DCMP. Thirteen new prescriptions by way of recessive principle excavating were acquired. These new prescriptions might be suitable to clinical treatments of variable syndromes. This article provides an useful clue to research and produce new drugs.

Objective To explore the influence of cerebral hemorrhage stress on endothelial progenitor cells(EPCs) proliferation and senescence. Methods Mononuclear cells from peripheral blood of patients with cerebral hemorrhage (CH group) and patients with the same underling diseases (control group) as the front were isolated and induced to EPCs. Proliferation, numbers of colonies and cells, senescence of EPCs were checked and compared between the two groups. Results Compared with control group, proliferation (0.270 ± 0. 074 vs 0. 185 ±0.050, t=3.802) ,numbers of colonies( (5. l0 ±0.79) cell/HPF vs ( 1.90 ±0.41 ) cell/HPF, t= 14.407) and cells( (75.15 ± 10.48) cell/HPF vs(57.10 ± 9.28 ) cell/HPF, t = 5. 157 ) of EPCs in CH group on the stress of cerebral hemorrhage were increased significantly (P ＜ 0.01 ), but senescence of EPCs ( (45.54 ± 5.74 ) cells/100 cells vs ( 46.86 ± 5.06 ) cells/100 cells, t = 0. 686 ) in two groups were not different (P ＞ 0.05 ). Conclusion Cerebral hemorrhage stress can increase proliferation of EPCs,but can not change the senescence destiny of EPCs.

Objective To understand the perception of health status in people with prehypertension. Methods Using the phenomenological method, 15 people with prehypertension were interviewed; the interview results were analyzed deeply. Results Five themes were extracted about health status:obscured perception about prehypertension and hypertension;absence of noticeable symptoms;necessity to change life-style, but lack of effective health self-management; many factors hindering effective health self-management; desire for professional help. Conclusions Perception of health status in people with prehypertension indicated deficiencies in health self-management. What they need were accessible professional support and intervention program that pay attention to people′s health belief and behavioral motivation.

The fracture of the axis arch is a rare uppercervical vertebrae fracture. It is easy to misdiag-nose. From 1971 to 1989, 7 cases of the fracturewere admitted to our hospital. Diagnoses were con-firmed by injury history, clinical features and X-ray films. The treatment results were as follows:six patients were in excellent condition and one pa-tient was in good one. The three following prob-lems were discussed: ①The mechanism of injury.②The misdiagnosis causes and its preventivemethods. ③Most patients can be treated conserva-tively and can be up. Only a few Type III fractureswill require operation after the failure of non-oper-ative treatment or at the time of conplicated injuryof the spinal cord occurring lately.

[Objective]To study the influence of hydroxypropyl methyl cellulose(HPMC) on injectability of calcium phosphate cements(CPC).[Method]Calcium phosphate cement(ICPC) with different content of HPMC(0～4%) was prepared.Injectability coefficient and consistency were tested to evaluate the injectability of the cements.[Result]Injectability increased as HPMC content increased.CPC injectability coefficient reached to 95% with lowest consistency when HPMC increased to 2%.CPC with 2% HPMC could be injected from syringe completely.Injectability began decrease when HPMC beyond 3%.Injectability decreased to 90% as HPMC increased to 4%,2% HPMC increased the injectability and decreased the consistency significantly,without any influence of setting time.[Conclusion]Rheology and injectability of CPC can be improved by HPMC significantly,Injection of CPC with 2% HPMC can be used for mini-invasive orthopedic surgery.
