To study the dynamic relationship of total health expenditure and economic growth so as to provide references for designing health economic policies. Methods: Using the regression models with multiple structural changes to estimate the structural change point of model parameter. Results: Compared to the elastic coefficient of economic growth, the total health expenditure and social health expenditure remained stably, the elasticity coefficient of government spending on health increased after decreased while elastic coefficient of personal spending health costs decreased after increased. Conclusion:In the early years of 1990s, the responsibility of government in health care financing funding weakened, which led to the increasing personal expenses. The situation began to reverse since 2004.

In recent years, many studies have claimed that the intrauterine infection is one of the most common causes of cerebral palsy. Cerebral palsy is associated with the brain injury directly or indirectly. With the direct mechanisms including breakdown of infected nerve cells of the mouse by intrauterine infection,hydrocephalus, dilation of the cerebral ventricles and ependymitis being illuminated uninterruptedly, researches of the indirect mechanism in cerebral palsy caused by intrauterine infection become the hot issue in the domain.Besides the inflammation mediators theory and down-regulated expression of development of the nervous system related factors, there were still several important elements which can cause brain damage such as placental excretive hormone imbalance, change of activity of Notch signaling and gene mutation/deletion and so on.Mechanisms and the interaction between them built up network effect.

[Objective]Combing the application of ginseng in the past physicians to make readers understand the efficacy of ginseng,and to be flexible in order to better serve human health.[Methods]Through consulting the ancient books of materia medica,the understanding of the ancient physicians and the application of hanren formulae were summarized and analyzed.[Results]Although the ancient physicians of the past believed that ginseng was subject to tonify five organs,quiet spirt,set soul,stop fright,remove pathogen,in addition to bright eye,happy,educational. long taking makes people fit and live longer,but with the development of the times,the Han dynasty in to nifying Qi torelieve thirst,tonify Qi for deficiency,the Tang dynasty in tonifying heart Qi,benefiting heart spirit,the Song dynasty in complement,benefiting Qi,the Ming dynasty in benefiting qi,Qing dynasty in tonifying Qi and Yin,modern in emergency first aid application.[Conclusion]Through the analysis of the application of ginseng in past dynasties,the complement ginseng can be more widely used in clinic,and better serve human health.

Rectal cancer is one of the common malignant tumors in China,and the incidence rate is rising year by year.Comprehensive treatment based on surgical operation is the major treatment of low rectal cancer.The treatment concept requires not only radical resection of tumor,but also preservation of the anal and urogenital function,to improve the quality of patients' life.By improving the accuracy of preoperative staging of rectal cancer,neoadjuvant therapy,and following the principle of total mesorectal excision,patients can benefit in terms of increased resection rate,decreased operation complication incidence,increased sphincter preservation,decreased local recurrence and increased overall survival rate.With the development of medical technology,minimally invasive surgery of low rectal cancer has been developed rapidly.In this paper,new progress in the surgical treatment of low rectal cancer will be reviewed.

BACKGROUND:Unicompartment knee replacement is more popular for smal trauma, rapid recovery, low complication and almost normal knee mechanics, and has been more and more used in clinic to repair single compartment knee disease. At present, there is no report about the influence of the angle of the single condyle prosthesis on the survival rate. OBJECTIVE:To evaluate the effectiveness of unicompartmental knee replacement for medial compartmental osteoarthritis of the knee in 4-6 years of fol ow-up. METHODS:Thirty patients with medial compartmental osteoarthritis of the knee were treated by unicompartmental knee replacement with Oxford system. Complication occurrence was observed. Curative effects were evaluated with Hospital for Special Surgery score before and 3 months, 6 months and 1 year after surgery. On anteroposterior view, the varus/valgus alignments of the tibial components were measured relative to the long axis of the tibia. On lateral view, flexion/extension of the femoral component was measured relative to the posterior femoral cortex. RESULTS AND CONCLUSION:(1) Primary healing of incision was obtained in al patients, and no infection or lower limb deep venous thrombosis occurred. (2) Al of the patients were fol owed up for 48-72 months. There was no prosthetic loosening, dislocation or revision for contralateral compartment and patel ofemoral joint symptoms. (3) Hospital for Special Surgery score was significantly increased to (90.47±4.05) (P=0.00). (4) Tibial placement angle of single condyle prosthesis:The axis of the prosthesis was perpendicular to the axis of the tibia in 21 cases. Varus placement:2° in 1 case, 4° in 3 cases, 5° in 2 cases, 6° in 2 cases, and 10° in 1 case. No valgus occurred in the tibial side. (5) Femoral prosthesis placement angle:The axis of the femoral prosthesis was paral el to the posterior edge of the femoral cortex in 22 cases, on the flexed position:4° in 2 cases, 5° in 1 case, 6° in 1 case and 7° in 1 case;in the extension position:3° in 1 case, 4° in 1 case and 5° in 1 case. (6) Results suggested that the unilateral condylar replacement for the repair of medial compartment osteoarthritis of the knee has a good initial effect. The middle-term and long-term efficacy needs longer fol ow-up study.

P300/CBP is one of the most important high molecular weight protein histone acetyltransferase ( HAT) Although it is encoded by multiple different genes , P300/CBP is highly homologous , Because they have the similar amino acid sequence and functions ,and belong to the same class of proteins ,normolly they are all called P300/CBP.P300/CBP is involved in the activation of many kinds of transcription factors ,the protein itself alsohas acetyltransferase activity ,and is capable of acetylation of 4 core histones and transcription factor .More and more studies have confirmed the relationship of P 300/CBP variation withmultiple human diseases , including in-flammation,diabetes,heart disease and especially cancer .In tumor P300/CBP is associated with some pathways , and these pathways play a different roles in the tumor .Although P300/CBP is usually regarded as a tumor sup-pressor factor ,is plays different roles in different tumors ,This review mainly introduces the relationship of P 300/CBP with some solid tumor disease genes ,related transcription factors and their signaling pathways .
