Objective To investigate the risk factors of postoperative complications of delayed hemorrhage,perforation and digestive tract stenosis after endoscopic submucosal dissection (ESD).Methods The complete data of 793 patients with digestive tract disease who underwent the endoscopic submucosal dissection in the Department of Digestive Surgery in our hospital from January 2011 to December 2014 were retrospectively analyzed.All of the patients were divided into delayed hemorrhage group (n =67) and nonbleeding group (n =726);perforation group (n =47) and non-perforation group (n =746);and digestive tract stenosis group (n =38) and non-stenosis group (n =755).The clinical basic data,lesion related data,and operation related data were independent risk factor and analyzed by single factor analysis and Logistic multiple factor regression analysis.Results The incidence of delayed bleeding,perforation and stenosis in patients with ESD were 8.45%,5.93%,and 4.79%,respectively.The results of single factor analysis:the risk factors for delayed bleeding were long-term use of anticoagulant drugs,gastric sinus disease,lesion diameter,and lesion excision (P < 0.05).The risk factors for postoperative perforation were the diameter of the lesion and the time of operation (P < 0.05).The risk factors of digestive tract stenosis were the esophageal lesions,the diameter of the lesion,and the depth of the lesion to the intrinsic muscle layer (P < 0.05).The results of multi factor Logistic regression analysis:the risk ranking of risk factors for delayed bleeding was gastric antrum occurrence lesion > lesions graded resection > long-term use of anticoagulants > lesion diameter (≥5 mm).The risk ranking of risk factors for perforation was operation time (≥90 mm) > lesion diameter (≥5 mm).The risk ranking of risk factors for digestive tract stenosis was esophageal lesion > lesion diameter (≥ 5 mm) > lesions depth to the muscularis propria.Conclusions For long-term anticoagulation,gastric antrum and fractional resection lesions of patients should pay attention to delayed bleeding.Patients with long operation time are easy to cause postoperative perforation.For long-term anticoagulation,gastric antrum and fractional resection lesions of patients should pay attention to delayed bleeding.

The text has isolated 267 strains LAB from the traditional fermentative food in Sichuan. Using agar plate proliferation experiment and double-layer agar plate proliferation experiment (eliminating the effects of organic acid and H_2O_2, decreased after treatment with trypsin and papain) to screen a LAB of Bacteriocins P158 which has antibacterial action to Escherichia coli, Staphylococcus aureus, Micrococcus luteus, Pseudomonas aeruginosa, Bacillus subtilis. P158 was isolated from fermented glutinous rice. Through detection of its appearance, physiological and biochemical characteristics and 16S rDNA gene sequence homology analysis, it was identified as Lactobacillus plantarum.

Protamex,flavorzyme and neutrase were used for bienzyme hydrolysis of Mytilus edulis.Protamex and flavorzyme were determined as the optimal hydrolases by analysis of hydrolysis effects.After bienzyme hydrolysis,ester forming yeast fermentation was used to prepare seasoner.The effects of fermentation of single or compound strains on the value of FAN were detected by formaldehyde titration method.The results showed that the value of FAN was 0.65% when the conditions of ester forming yeast 1274 were as follows:inoculation volume 5%(v/v),fermentation temperature 28℃ and culture time 72h after bienzyme hydrolysis;the value of FAN was 0.78% when the hydrolytic solution was fermented by compound strains including ester forming yeast 1274 and 1202 under the same fermentation conditions.After fermentation of ester forming yeast,the seasoner gave a full-bodied smell of ester with fermentation flavour.

Objective To observe the expression of matrix metalloproteinases(MMP)-1,MMP-3 and iNOS in cartilage of experimental rabbit osteoarthritis at different time intervals after anterior cruciate ligament transection(ACLT)operation.The aim of this study is to provide the theoritical evidence for using ACLT rabbit model in Osteoarthritis(OA)research.Methods Unilateral ACLT was performed on 27 randomly selected while rabbits and underwent unilateral arthrotomy was performed on the other 9 white rabbits as the control group.Nine randomly selected white rabbits in experimental group were killed and 3 white rabbits in the control group at 4th,8th and 12th week respectively.Cartilage degradation of femoral condyles was evaluated macr-oscopically,mRNA expression level and protein expression level of MMP-1,MMP-3 and iNOS was measured by reverse transcription-polymerase chain reaction(RT-PCR)and immunohistochemistry respectively.Results Forepart OA cartilage degradation was observed at the 4th week and became more severe at the 8th week after ACLF.Afterpart cartilage degradation was evident at the 12th week after ACLT while cartilage still remained normal in the control group,mRNA expression level and protein expression level of MMP-1.MMP-3 and iNOS were increased at the 4th week and became higher gradually at the 8th,12th week after ACLT compared with the control group.Expression distribution of MMP-1,MMP-3 and iNOS bad different patterns respectively.Conclusion It is suggested that the process of OA cartilage degradation can be simulated by ACLT model and MMP-1,MMP-3 and iNOS may be good markers in therapeutical research of OA.

Objective To investigate the prevalence of adult osteofluomsis in the endemic fluomsis areas in Tianjin and to provide scientific foundation for endemic fluorosis.Methods Stratified sampling in 55 villages were selected in 3 areas with slight,moderate and severe fluorosis regions in Tianjin from April to June in 2008.Water fluorine were tested and clinical osteofluorosis examinations were conducted to the population aging 16 and above in the villages.Tweenty villages were selected randomly in the slight,moderate and severe fluorosis regions.X-ray osteofluorosis examination were conducted to patients and suspected patients in these 20 villages.Results The geometric mean fluoride content in the water for the 3 areas were 1.35 mg/L,3.44 mg/L,5.49 mg/L,respectively.The prevalence of osteofluorosis were 36.7%(44/120),20.6%(33/160),39.4%(43/109),respectively.The prevalence of osteofluorosis Was increased gradually(r=0.534,P<0.01)and the symptoms and signs of the disease were more serious(H=84.813,P<0.01).The prevalence of X-ray diagnosis Was increased gradually(r=0.990,P<0.01)and signs of the disease were more severe(H=25.169,P<0.01)with an increase in age.There was no statistical significance of prevalence rate of osteofluorosis between males and females,regardless if it Was a clinical diagnosis(X2=0.343,P>0.05)or an X-ray diagnosis(X2=3.532,P>0.05).Conclusions Adult osteofluorosis to a certain extent is still prevalent in the fluorosis areas in Tianjin.Endemic fluorosis is still rampant.Improving water in fulorosis areas should be mandatory.

This study is to investigate the anti-tumor activities of a novel cyclophosphamide derivate 4, 6-diphenyl cyclophosphamide (9b) in vivo and in vitro, and its possible mechanism of action. The inhibitory effects of 9b on human hepatoma cell line HepG2, human breast carcinoma cell line MCF-7 and human myeloid leukemia cell line K562 were measured by MTT assay in vitro. Cell cycle distribution and apoptotic rate were evaluated by flow cytometry. To evaluate the anti-tumor effect of 9b in vivo, mouse model bearing inoculated H22 tumor was established. The results indicated that 9b could inhibit the proliferation of HepG2, MCF-7 and K562 cells in a dose and time dependent manner. The ICo50 values of 9b were 32.34 micromol.L-1 to HepG2 cells, 87.07 micromol.L-1 to MCF-7 cells and 149.10 micromol.L-1 to K562 cells after incubation for 48 h. The results of flow cytometry indicated that after being treated for 48 h with different concentrations of 9b, the ratios of HepG2, MCF-7 cells at the Go/G1 phase and K562 cells at the G0/Gl phase and G2/M phase increased significantly compared with control group, and the apoptotic rate increased with the increase of the concentration of 9b. 9b could significantly reduce tumor weight of H22 solid tumor mouse model in vivo. To summarize, 9b showed significantly anti-tumor activity in vivo and in vitro, of which the mechanism might be associated with the change of cell cycle distribution and induction of tumor cell apoptosis.
