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.

Objective To retrospectively study histopathologic features of ulcerous colitis (UC) and Crohn's disease (CD) by endoscopic biopsy. Methods Data of age, gender and intestinal involvement of 106 cases of CD and 180 cases of UC confirmed by pathology were reviewed. Mucosal architecture, chronic inflammation, acute inflammation and epithelial features were evaluated based on histopathological criteria.These features were compared between the two groups. Results Compared with CD cases, UC showed significantly higher percentage of architectural disorders ( P ＜ 0. 05 ), lower percentage of discontinuous chronic inflammation ( P ＜ 0. 05 ) and higher incidence of cryptitis, crypt abscesses and polymorph cells in lamina propria (P ＜0. 05 ), and higher rate of epithelium damage, flattened and less mucous cell as well. Granuloma, pseudo pylorus glands metaplasia and narrow ulcer only occurred in CD cases. Lesions of 90% (162/180) cases of UC were limited to colon, while those of 28% (30/106) of CD cases to ileocecum, and those of 56% (59/106) CD cases involved different parts of gastrointestinal tract. Conclusion Diagnosis of CD and UC needs comprehensive analysis. Diagnostic evidence for CD includes focal involvement of ileocecum, the multifocal involvement in gastrointestinal tract, granuloma, discontinuous inflammation, pyloric gland metaplasia, while that for UC includes mucosal damage limited to colon, continuous chronic inflammation, architectural disorders, or epithelial damage.

Objective To discuss the indication and safety of vaginal birth after cesarean .Methods Prospective analysis was clone the 63 cases of successful vaginal delivery from scarred uterus during Jan 2009 to Dec 2012 in this hospital .Results Intensive observation revealed 21 successful cases of vaginal delivery without occurrence of uterus rupture or neonatal suffocation .Postpartum hemorrhage occurred only once .Conclusion Vaginal birth after cesarean is safe as long as its indication is strictly controlled .

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.

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.

Objective To study the effect of anti-hypertensive therapy on the characteristics of platelet in essential hypertension(EH) patients. Methods Thirty-two healthy people(CT) and 37 patients with primary hypertension (gradeⅠ) were recruited . Blood pressure and 4 platelet parameters: platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW) and platelet hematocrit (PCT) were determined by whole blood automatic analysis apparatus. Results The 4 platelet parameters were increased in hypertension patients compared with healthy people and decreased after anti-hypertensive therapy[PLT:(before 201.8?72.9 vs after 187.1?68.6 )10~ 9 L+{-1}; MPV:(before 10.3?1.9 vs after 10.0?1.9)fL, PDW:(before 15.5?1.1 vs after 15.2?1.0)fL; PCT:(before 0.198%?0.047% vs after 0.187%?0.036%)](P
