To summarize the present situation of research on amylolytic lactic acid bacteria and its amylase,and the fermentation technology of amylolytic lactic acid bacteria.The amylolytic lactic acid bacteria have the ability of secreting amylase,can direct ferment starchy material into lactic acid without hydrolysising processes,simplify the production process,and saving the equipment investment,thereby,decrease the cost of production.Amylolytic lactic acid bacteria isolated from traditional fermented food,or from organic waste and kitchen waste.The mechanism of direct utilize starch raw materials by the amylolytic lactic acid bacteria were introduced,the fermentation technology of amylolytic lactic acid bacteria were compared.Meanwhile it was pointed out that through mutation breeding and genetic engineering methods gain the potent amylolytic lactic acid bacteria,and use the advanced fermentation and separation technology can improve the productivity of lactic acid.

Objective To explore the values of CT virtual gastroscopy (CTVG), three dimensional (3D) and axial imaging by multi slice spiral CT (MSCT) in the preoperative assessment of gastric carcinoma. Methods Fifty two patients with gastric carcinoma proven by means of biopsy underwent CTVG, 3D imaging using the surface shaded display (SSD) and Raysum, and axial imaging. MSCT was first performed after the ingestion of gas, and a second tri phase MSCT scan was performed after the ingestion of water. The results were compared with those of fibrous gastroscopy (FG) and surgical pathological findings. Results The detection rates of gastric lesions with CTVG, 3D and axial imaging by MSCT were 98.1%, 96.2%, and 96.2%, respectively. The accuracy of judging gross type of advanced gastric carcinoma using CTVG combined with 3D imaging, FG,and axial imaging was 92.5% , 82.5%, and 75.0%, respectively.Statistical difference existed in CTVG combined with 3D imaging and axial imaging (P

Electronic case report forms (eCRFs) instead of the traditional paper case report forms (pCRFs) are increasingly used by investigators and sponsors of clinical research. We include a total of 14 phase III studies (8 pCRF, 6 eCRF) to compare paper and electronic data documentation both quantitatively and qualitatively in clinical studies. The result suggests that adaptions of electronic data capture (EDC) in clinical trials have the advantages in optimization of data capture process, improvement of data quality and earlier clinical decision compared to paper-based methods. Furthermore, the successful implementation of EDC requires accouplements with corresponding data management processes and reallocation of resources.

AngiotensinⅡ( AngⅡ) is the main functional bioac-tive peptide of the renin angiotensin system,and its basic function is to regulate salt-water homeostasis and blood pressure. Howev-er,recent studies have shown that AngⅡ plays a very important role in tumor formation and angiogenesis by acting on its type 1 receptor (AT1R) as a kind of potential growth factor. This arti-cle is a brief overview of the research on effects of AngⅡ-AT1R system in the process of tumor angiogenesis in recent years.
