It is well known that oligosaccharides in glycoproteins and glycolipids play crucial roles in a variety of cellular functions, such as proliferation, differentiation, and intercellular communications. The oligosaccharides of cell are increasingly being recognized as one of the most prominent biochemical alterations associated with malignant transformation and tumorigenesis. Glycosylations in different cell cycle and cell growth periods are significantly distinct, and these differences affect the cell cycle progression. In the past decades, along with the advances in genomics and proteomics, the functional significance of cancer-associated changes in glycosylation has been revealed. Eukaryotic organisms depend on an intricate and evolutionary conserved cell cycle to control cell devision. Mistakes in cell cycle process lead to cancer. This review highlights the relations between cell cycle and glycosylation changes in cancer cells.

Objective To establish a rapid and accurate analysis method for food-derived ACE inhibitory peptides activity in vitro.Methods Reaction time of ACE and substrate was by measuring the hippuric acid liberated in the ACE reaction mixture at regular intervals;An optimal RP-HPLC method to measure food-derived ACE inhibitory peptides activity in vitro was set up.The hippuric acid from ACE reaction mixture(sea cucumber peptides were regarded as ACE inhibitor) was estimated by Zorbax SB-C_(18) analytical column with acetonitrile and ultrapure water as mobile phase.Results The reaction time of ACE with substrate was determined at sixty minutes;The elution was carried out with the ratio of acetonitrile to ultrapure water was 1:1(0.1%TFA) at a flow rate of 0.4 mL?min~(-1).The ahsorbance of the eluent was monitored at 228 nm,and column temperature was 25℃.The relationship between hippuric acid concentration and peak area exhibited a good linearity in the concentration ranges of 0～200?g?mL~(-1) and 200～800?g?mL~(-1).The RP-HPLC method was further validated by captopril,the oyster hydrolysate and the anchovy hydrolysate.Conclusion The method has been proved to be convenient,accurate and suitable for the analysis of foodderived ACE inhibitory peptides activity in vitro.

each group were sacrificed, respectively. Distributions of BrdU positive cels and ChAT positive cels were detected by S-P immunohistochemical method. The learning and memory abilities of rats were detected by Morris water maze system.
RESULTS AND CONCLUSION:BrdU positive cels were mainly distributed in the cortex and hippocampus, especialy around the blood vessels, and there was the presence of focal aggregation. A smal amount of BrdU positive cels were observed in the basal ganglia and thalamus as wel as in the ependyma. BrdU positive cels were counted at different time after operation. The number of BrdU positive cels decreased with time, and only a smal number of BrdU positive cels were observed at 60 days after transplantation. The number of ChAT positive cels at different time after transplantation was ranked as folows: neural stem cel transplantation group > model group > sham operated group (P < 0.05). Compared with the model group, the time for searching the platform was significantly lower in the neural stem transplantation group and sham operated group, but the number of crossing the platform was significantly higher in the neural stem cel transplantation group and sham operated group (P < 0.05). The results show that neural stem cels could be transplanted into the rats with vascular dementia, and the cels could survive and migrate in the brain of rats and significantly improve the learning and memory ability. This mechanism may be related to the differentiation and growth of cholinergic neurons in the hippocampus.

Objective To provide data evidence for brucellosis prevention by a retrospective analysis of brucellosis epidemiologic feature in Ji'nan Infectious Disease Hospital from 2010-2014.Method The brucellosis patients with confinned diagnosis from 2010 to 2014 admitted to Ji'nan Infectious Disease Hospital were included in this study,and their epidemic data were statistically analyzed,including time,age and occupation distributions.Results There were 1 010 brucellosis patients in total in Ji'nan Infectious Disease Hospital from 2010 to 2014,and 12 cases,69 cases,134 cases,274 cases and 521 cases,respectively,in each year,which showed rapid rising trend.There were two peak times,the first was from April to August,the incidence was 9.1％ (92/1 010),12.2％(123/1010),13.4％ (135/1010),11.1％ (112/1010) and 10.7％ (108/1010),respectively,in each month;the second was January,the incidence was 9.4％ (95/1010).The diagnosed rate within 1 week of onset only accounted for 13.4％ (135/1010),and 72.4％ (731/1010) patients were diagnosed for more than two weeks after the onset.The male incidence of brucellosis was higher than the female,and the sex ratio was 2.36:1.00.In terms of age distribution,40-49 and 50-59 were both peak ages,with incidence of 29.3％ (296/1 010) and 25.0％ (252/1010),respectively.The professional was given priority to farmers and herdsmen (85.6％,865/1 010),and 96.4％ (974/1010)of the patients had a clear exposure history,mainly related to sheep,cattle,pigs and other livestock,also related to pets and milk.Conclusions The brucellosis patients that received in Ji'nan Infectious Disease Hospital are increased significantly in the recent 5 years,and their transmission is closely associated with livestock breeding and processing.Most patients have failed timely diagnosis in the early days,which should catch enough of our attention.

Objective To discuss the reasons,surgical procedures and prognosis of multiple-operations for intra-and extrahepatic cholangiolithiasis.Methods The retrospective cohort study was adopted.The clinical data of 85 patients with intra-and extrahepatic cholangiolithiasis who underwent multiple-operations at the Second Affiliated Hospital of Anhui Medical University from January 2006 to January 2015 were collected.Individualized operations were determined according to the distribution of stones and liver functional reserve,including stones removal by incising bile duct and external biliary drainage,Roux-en-Y hepaticojejunostomy and hepatolobectomy or segmental hepatectomy.The treatment followed the principles as complete removal of stones,complete resection of lesions,correction of stenosis and adequate drainage.Bile was extracted during operation for bacilli culture.Patients received the postoperative symptomatic treatments,including anti-inflammation,hemostasis,liver protection,acid inhibition and nutritional support.The observation indicators included reoperation reasons,operation method,operation time,volume of intraoperative blood loss and transfusion,hepatic inflow occlusion,stone clearance rate,postoperative complications and treatments,bacilli culture of bile,results of pathological examination and duration of hospital stay,results of follow-up.The follow-up using outpatient examination and telephone interview was performed to detect postoperative living conditions and results of abdominal ultrasound once every 3 or 6 months in patients without stone residue and once every 1 month in patients with stone residue from postoperative week 6 to December 2015.Measurement data with normal distribution and with skewed distribution were represented as x ± s and M (range),respectively.Results (1) Reasons of reoperation:85 patients had stone residue or recurrence,including 7 combined with stenosis of bilioenteric anastomosis,5 with secondary malignant biliary tumors and 2 with gastrointestinal stromal tumor invading intrahepatic bile duct.(2) Intraoperative status of reoperation:of 85 patients,25 received partial hepatectomy + stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage,21 received partial hepatectomy + stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,13 received stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage,8 received stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,5 received partial hepatectomy + removal of former bilioenteric anastomosis + choledochoscopy exploration + T-tube drainage,4 received former intestinal Y-loop resection + stones removal by choledochoscopy + Roux-en-Y hepaticojejunostomy,3 received stones removal by incising intrahepatic bile duct + choledochoscopy exploration + T-tube drainage,3 received partial hepatectomy + residual gallbladder resection + stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,2 received partial hepatectomy + residual gallbladder resection + stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage and 1 received residual gallbladder resection + removal of former bilioenteric anastomosis + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy.Operation time and volume of intraoperative blood loss of the 85 patients were (259 ± 66) minutes and (180 ± 142) mL,respectively.Seven patients underwent intraoperative blood transfusion and 17 underwent first hepatic hilum occlusion.ALl the 85 patients received intraoperative choledochoscopy exploration.The immediate and final stone clearance rates were 62.4％ (53/85) and 87.0％ (67/77).(3) Postoperative status of reoperations:of 85 patients,45 had postoperative complications.Sixteen patients with incision infection were improved by wound drainage and dressing,anti-infection and supporting treatments without other treatments.Ten patients with pleural effusion were out of hospital after effective anti-infection and nutritional support treatments.Eight patients with biliary fistula were discharged from hospital after abdominal drainage.Six patients with incision infection combined with pleural effusion were discharged from hospital after wound drainage and dressing,anti-infection and nutritional support treatments.Among 5 patients with bile duct bleeding,1 was self-healing,1 underwent reoperation and 3 were improved by conservative treatment.The bacilli culture of bile in 68 patients was positive,and bacteria mainly consisted of Escherichia coli,Enterobacter cloacae,Pseudomonas aeruginosa and Klebsiella pneumoniae.Of 85 patients,78,5 and 2 patients were respectively confirmed with hepatolithiasis,bile duct cell adenocarcinoma combined with stone recurrence and choledocholithiasis combined with interstitialoma by pathological examination.Duration of hospital stay was (21 ±8)days.(4) Results of follow-up:77 patients were followed up for a median time of 32 months (range,6-108 months) with an overall follow-up rate of 90.6％ (77/85).During follow-up,50 patients had good survival,27 had poor survival including 11 with stone residue,9 with stone recurrence and 7 with bile duct canceration,and 7 died of no operation of secondary tumors.Conclusions Stone residue and recurrence are the main reasons for reoperation.The individualized surgical methods are determined according to preoperative stone distribution,with or without atrophy of liver lobe,with or without canceration and condition of liver function,which can increase the stone clerance rate,reduce the stone residue and recurrence rates and avoid reoperation.
