Objective To investigate clinical characteristics of the multi-center breast DCIS (ductal carcinoma in situ), in order to improve the rate of early diagnosis. Methods Clinical data of 23 multi-center breast DCIS patients admitted and operated on from September 2003 to February 2009 at our department were retrospectively reviewed. Results There were 4 cases associated with nipple discharge,and 18 cases with preoperative negative physical examination (78%). In the preoperative examination within 6 months, the positive rate of mammography was 90% mainly characterized by the existence of diffuse and multiple small calcifications. The positive rate of MRI was 25%, B ultrasound had no positive findings. The patients that were confirmed multi-center breast DCIS by intraoperative frozen section examination received mastectomy and ipsilateral axillary L1, L2 lymph node dissection. Conclusion The diffuse and multiple small calcification is one of early clinical characteristics of multi-center breast DCIS. Although the disease has a wide range of lesion, it still is an early tumor, and has a favourite prognosis after comprehensive treatment.

OBJECTIVE: To introduce advances of cerebrovascular stent at home and abroad, analyze causes for complications following stenting and explore the biocompatibility of cerebrovascular stent and host.METHODS: A computer-based online search of Medline database (1989/2009) and CNKI (1989/2009) was performed to select related articles. According to inclusion and exclusion criteria, the collected articles were selected and evaluated. The treatment advances, complications, and stent biocompatibility were described and summarized to explore the current status, complication and biocompatibility of various cerebrovascular stents.RESULTS: The content of articles was summarized. Intracranial stent is commonly used in clinic. The diameter of vessels confines diameter of stent, so different diseases have different requirements for diameter of stents. The complications following stenting include retroperitoneal hematoma, carotid sinus, hypertransfusion syndrome, cerebral angio spasm and thrombosis. In various stents, polymer, eluting and drug stents have better biocompatibility compared with metal stent, and can effectively prevent restenosis.CONCLUSION: Cerebrovascutar stenting is one of the treatments for cerebrovascular diseases. During the treatment, sufficient operative preparation, appropriate stent and indication are important to avoid complications. Of various stents, polymer and drug stents have good biocompatibility, and the biocompatibility of other stents requires improvement.

Rare sugars were defined as monosaccharides and their derivatives that rarely exist in nature. They played an important role in food, health, medicine and etc A strategy for bioproduction of rare sugars, namely Izumoring, was described. By the Izumoring method, all monosaccharides and polyols could be linked, using enzymatic reaction with D-tagatose 3-epimerase, aldose isomerases and polyol dehydrogenases. Izumoring for hexoses, pentoses and tetroses were designed respectively. According to this strategy, the bioproduction routes of various rare sugars, using microbial and enzymatic reactions, could be obtained. In addition, the future research tendency of biotransformation of rare sugars was put forward.

Objective To explore a method for development of carbon tetrachloride-induced cirrhotic model in rabbit and establish a portal vein delivery system in this model.Methods Male New Zealand white rabbit was subcutaneously injected carbon tetrachloride twice weekly,and the liver pathology and hepatic hydroxyproline content were examined after 12 weeks of injection.Portal vein catheterization was introduced through the terminal branch of mesostenium vein.The injection end of the catheter was embedded subcutaneously in the abdominal wall of the animal.The portal delivery was implemented by percutaneous puncture of the injection cap.Results After 12 weeks' of carbon tetrachloride administration,the rabbit liver developed typical pseudo lobule,and the liver hydroxyproline content increased 3.5 times compared to normal control.The portal vein delivery system could be maintained as long as 12 weeks.Conclusion A successive method to induce rabbit liver cirrhosis is developed,and a simple and economic animal portal vein delivery system is introduced.
