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.

Along with the mediated society,there are the problems in students'current media literacy,such as the alienation of media using,inability to distinguish'media reality'and'objective reality',lacking of media ethics and consciousness of self-discipline.Based on the analysis of these problems,in combination with the actual college education,we put forward the realization ways and the corresponding strategies to improve the students'media literacy.

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.

BACKGROUND: Self-repairing capability of articular cartilage tissue is poor, due to lack of the distribution of vessels and lymph.OBJECTIVE: To concisely describe the research progress of autologous chondrocyte implantation (ACI), including matrix-induced autologous chondrocyte implantation (MACI), in vivo scaffolds, and related tissue engineering technologies, and to prospect the future developments.METHODS: A search across the databases of ISI Web of Knowledge and PubMed (1979 to February 2009) was performed, with key words of "articular cartilage, transplantation, stern cells, tissue engineering". As well, a search in the database of CNKI (1979 to Febraruy 2009) was performed with the key words of "articular cartilage, repair, tissue engineering". Contents referring to ACI,MACI, in vivo scaffolds and related tissue engineering technologies were included, while contents regarding to the clinical imaging of articular cartilage defects, intracellular signaling pathways in chondrocytes, or gene therapy for articular cartilage defects were excluded.RESULTS AND CONCLUSION: 824 articles were obtained from the preliminary search across the databases. Based on the nominated evaluation criterions to the outcome, analysis focusing on ACI, MACI, in vivo scaffolds and related tissue engineering technologies was performed. As the most successful treatment for articular cartilage defects in the past decade, ACI has undergone a significant development. Recent improvements of ACI include MACI, in vivo scaffolds and related tissue engineering technologies, which exhibit relatively more success in engineering and clinical practice. Nonetheless, limitations still exist and therefore, further researches are required. As a promising alternative of ACI, MACI is more and more widely used in clinical practice for treating articular cartilage defects these years. The long-term curative effect of MACI, however, requires further clinical data to confirm. In addition, other improvements of ACI, in terms of material science, cytology and molecular biology, have been also provided by the developments of in vivo scaffolds and related tissue engineering technologies.

OBJECTIVE To investigate the resistance of Staphylococcus to erythromycin and clindamycin and detect the percentage and gene for inducible resistance in Tai'an.METHODS The susceptibilities of Staphylococcus to erythromycin and clindamycin were examined by Kirby-Bauer disc agar diffusion test and the inducible erythromycin resistance to clindamycin was checked by D-test according to the standards of NCCLS,and the resistance genes msrA,Vgb,sat4,ermA,ermB and ermC were detected by using PCR technology.RESULTS Among the 326 strains,162(44.12%)were all resistant to erythromycin and clindamycin;68(20.86%)were resistant to erythromycin and sensitive to clindamycin but they were positive in D-test;42(12.88%)were resistant to erythromycin and sensitive to clindamycin but they were negative in D-test.The rates of inducible resistance of MRSA,MSSA,MRCNS and MSCNS to clindamycin were 40.00%,56.25%,63.38% and 66.67%,respectively among the Staphylococcus which were resistant to erythromycin and sensitive to clindamycin.The gene ermC was the main one for inducible erythromycin resistance to clindamycin.The percentage of gene ermC was 85.29% and that of ermC and sat4 either was 7.35%;all the others were negative.CONCLUSIONS The rate of inducible erythromycin resistance to clindamycin in our area is relatively high,and D-test in clinical microbiology laboratory should be done so that the physicians can select the reasonable MLSB antimicrobial agents.

[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.
