Angiogenesis is one of the important pathological characteristics in the development of tumor growth. Hence ,an?ti-angiogenes is has become a hot topic in the field of cancer research. The current strategy for anti-angiogenesis therapy is to restore the angiogenic balance which is broken in the tumor via either block of proangiogenic factorsor application of angiogenic inhibitors. Endogenous angiogenic inhibitors show more promising prospects compared with proangiogenic factor antagonists. However ,the un?derlying mechanisms for the angiogenic inhibitors remain to be thoroughly elucidated. There are two kinds of endogenous angiogenic inhibitors,one is the hydrolyzed fragments of precursor protein,such as plasminogen Kringle 5(K5),angiostatin/kringle 1~4,end?ostatin,etc;the other is cell secreted proteins,such as pigment epithelium-derived factor(PEDF),kallikrein-binding protein (KBP/kallistatin),antithrombin,etc. Here we summarized the research progresses on the biological functions,underlying mecha?nisms of tumor angiogenesis and application prospects of K5,PEDF,and KBP,so as to provide insights into the antiangiogenic ther?apies of tumor in the future.

Issues of Chinese medical health reform are analyzed and approached associated with the US federal medical health system. We made the suggestions that establish the public health service system covering both urban and country residents, push on the reform of medical insurance, drug circulation and medical system. We advocate that implement the scientific development view and hold the opportunity, impel the medical health reform in general.

Cognitive behavior therapy (CBT) has been proved to be an effective psychological treatment method for depression,especially for mild-to-moderate depression,however,due to the influence of various factors,its application in patients with depression is limited.Studies abroad have confirmed self-help intervention based on CBT has good effects on patients with depression.By reviewing efficacy of self-help interventions based on CBT on depression,it can be known that most of the literatures support that self-help interventions based on CBT has good effects on depression.Related researches abroad have been more mature,but few similar studies have been conducted in our country.So self-help CBT for depression has broad prospects in our country,which can play an important role in the prevention and therapy of depression,alleviating the shortage of medical resources,and reducing the patients' medical expenses,etc.Based on bibliotherapy (a major form of self-help interventions based on CBT),future studies need to learn from foreign practice to expand the audience to the clinic,community and non-clinical patients,in order to provide advice for interventions for depression in China.

[Summary] Poorly controlled hyperglycemia is closely associated with adverse outcomes during pregnancy. As the prevalence of diabetes rapidly increases ,the management of diabetes during pregnancy has been a significant and urgent need in clinical practice. This article reviewed the hot spots in the research field of gestational diabetes mellitus (GDM ) and pregnancy with diabetes mellitus ,including progresses on the risk factors for GDM and the long term effects of diabetes during pregnancy on mothers and offspring. This was followed by a body of evidences on the clinical benefits of improved glycemic control during pregnancy ,current therapeutic strategy using insulin as the golden standard as well as the potential advantage of insulin determir due to its unique pharmacokinetic‐pharmacodynamic (PK‐PD ) profile in this therapeutic area. Finally ,the authors summarized data from clinical trials on the usage of insulin detemir in pregnancy and in particular went over the designs and results of two randomly controlled trials investigating the efficacy and safety of insulin detemir in pregnancy patients with T1DM. Currently available data proved that insulin detemir was effective in improving glycemic control with a good safety profile in diabetic pregnant patients ,which may serve as an ideal choice in the management of diabetes during pregnancy.

Chronic kidney disease-mineral and bone disorder (CKD-MBD) refers to a series of clinical symptoms and biochemical and imaging abnormalities caused by minerals and calcium phosphorus metabolic disorder,which is associated with chronic kidney disease (CKD).Since 2006 ,the concept of CKD-MBD was put forward for the first time,doctors are increasingly paying more attention to it.This review introduces the epidemiological characteristics, clinical manifestation, examination methods, diagnostic criteria and the research progress of treatment and prevention of CKD-MBD.

Objective To study the effect of probiotics on the change of intestinal permeability and inflammatory reaction after surgery of colorectal cancer.Methods Sixty patients who underwent colonic surgery were randomly divided into two groups:probiotic group and control group,with 30 cases in each group.Each group received nutritional support of the same nitrogen and calorie from day 3 to day 7 after operation.The patients in probiotic group were orally administrated probiotic(2 g/d)from the first day after surgery for 7 days.Every patient's body temperature and heart rate were observed after operation,and white blood cell counts were observed before operation and on day 1,5,8 after operation.The levels of microbial DNA in whole blood and plasma D-lactate,and urine lactulose/mannito(L/M)ratio were measured before operation and on day 1 and day 8 after operation,respectively.In addition,the occurrence of postoperative systemic inflammatory response syndrome(SIRS)and complications of inflammation were closely observed.Results The average heart rate in postoperative 5 days was significantly lower in probiotics group than that in control group(P0.05).Conclusion Probiotics can decrease intestinal permeability and maintain the intestinal barrier function after operation.It may be helpful for the recovery of patients with early inflammatory response after surgery of colorectal cancer.

Carbon nantubes composites draws more and more attention these days. Its application provides new potential for the reinforcement and toughness of dental ceramic. In this paper, the properties of carbon nanotube, carbon nanotube based ceramic composites and its mechanics of toughness, and the future trend of carbon nanotube in dental ceramic material, have been reviewed.

The effect of artrial natriuretic polypeptides on the intracellular free. calcium concentration of immune cells of spontaneously hypertensive rats has been investigated. It was found that artrial natriuretic polypeptides could raise directly the intracellular free calcium concentration of thymocytes, splenocytes and lymphonode cell, or cooperate with Con A in increasing the intracellular free calcium concentration of rat lymphocytes and T lymphocytes except for B cells. It was also found that artrial natriuretic polypeptides could cooperate with IL-2 in increasing the intracellular free calcium concentration of rat lymphoblast induced by Con A. The extent of increased intracellular free calcium concentration induced by artrial natriuretic polypeptides in immune cells of spontaneously hypertensive rats was lower than that of WKA rats.

BACKGROUND:3D printing, a rapid prototyping technology, is considered to be one of the symbols of the third industrial revolution. There are many kinds of 3D printed materials, which have a wide range of clinical applications.OBJECTIVE: To systematically introduce 3D printed biological materials, to summarize the application advances of 3D printing technology in the printing and production of bone, artificial limbs, dentures, skin, blood vessels, stent, implant prosthesis, and tumor models, as well as to investigate the performance conditions of 3D printed biomaterials based on the advantages and disadvantages of the currently used biomaterials, in order to provide reference for future research.METHODS:A computer-based search of CNKI, Wanfang, VIP, CBM, PubMed was performed to search relevant articles published from 2010 to 2016, using the keywords of three-dimensional printing/3D printing/3-D printing; biomaterials; clinical application in Chinese and English, respectively.RESULTS AND CONCLUSION: Great progress in 3D printed biomaterials has been made. However, there are some defects in the existing printed materials, such as high cost, low printing precision and poor biodegradability. Only if the problem of materials is solved, can we continue to develop 3D printing technology. New breakthroughs in 3D printing in the field of medicine have been made, and new technologies and new materials have been applied in clinical practice. Systemic summarization of these application achievements of 3D printing in the field of medicine can provide reference for future medical research.
