Urid acid is one of the terminal metabolites of human body.More and more attention was paid to its metabolic mechanisms in intestinal tract;however, few studies were seen so far.This study aims to illuminate the metabolic mechanism of uric acid in intestinal tract by two ways:one is the transporters associated with intestinal epithelium, including ABCG2 and SLC2A9, the other is decomposition of uric acid by intestinal flora.We hope this review can provide new insights to decrease blood uric acid and treat urate-related diseases, and also provide a new way to alleviate drug-induced kidney damage.

Objective To investigate the influence of anti-depression therapy on inflammatory cytokines and quality of life(QOL) in patients with acute coronary syndrome(ACS) complicating depression.Methods Ninety-four patients with ACS complicating depression(HAMD total score ≥8) were randomly divided into the treatment group and control group,47 cases in each group.The control group was given the conventional drug therapy,pantoprazole 40 mg /d,on this basis the treatment group was given sertraline 50 mg/d.The treatment course in the two groups was 6 months.The change of HAMD score,inflammatory cytokines,QOL and incidence of adverse cardiovascular events were observed and compared between the two groups.Results The HAMD score after 3-,6-month treatment in the treatment group was significantly lower than that in the control group (P<0.05).The levels of inflammatory cytokines after treatment in the two groups were all reduced,while the IL-6 and TNF-α levels in the treatment group were lower than those in the control group (P<0.05);the scores of all dimensions and total scores of SAQ after 6-month treatment in the treatment group were significantly improved,and the anginal attack situation,treatment satisfaction degree and total score were significantly higher than those in the control group (P<0.05).During 12-month follow-up,the incidence rate of major and minor cardiovascular events,alimentary tract hemorrhage events and total events had no statistical difference between the two groups(P>0.05).Conclusion The antidepressant therapy is safe and effective for treating ACS patients,can effectively improve the depression emotion,inhibits inflammatory reaction,relieves somatic symptoms,and improves QOL.

Objective To assess the safety and feasibility of hybrid trans-gastric endoscopic and laparoscopic cholecystectomy in a porcine model.Methods A total of 6 pigs underwent hybrid trans-gastric endoscopic and laparoscopic cholecystectomy from July to October,2010 under general anesthesia.The operation time and complications during the procedure were recorded,as well as post-operative changes of eating habits and weight.Animals underwent autopsies on post-operative days(POD)14 for evaluation of infection,abscesses and adhesion.Results All procedures were successfully performed and all dogs survived.There was no severe complication except for hemorrhage in one porcine,which was successfully managed under laparoscopy.The mean operation time was 87mins(ranging from 69-124 mins).After the operation,there was no change in eating habits or weight.At autopsy on POD 14,no abscess or hemorrhage was found.Sites of gastric closure were found to be completely healed.Conclusion The hybrid approach increases the safety of initial gastric puncture and gastric wall incision,simplifies peroral trans-gastric cholecystectomy,and decreases invasiveness of laparoscopic surgery.It is a bridge between laparoscopic and transluminal surgery.

Objective To prepare dual-targeted microbubbles carrying both anti-CD34 monoclonal antibody and anti-ICAM-1 monoclonal antibody,to identify its basic characteristics,and to investigate its targeting performance in vitro.Methods ICAM-1-targeted microbubbles (MgIcAM-1),CD34-targeted microbubbles(MBcD34) and dual-targeted (with both monoclonal antibodies) microbubbles (MBD) were prepared by biotin-avidin bridging chemistry method.The targeted microbubbles were observed under light microscrope and characterized by a Mastersizer 3000,DFY software,laser confocal microscopy,and flow cytometry.The targeting specificity and attachment capability of dual-targeted microbubbles to endothelial progenitor cells (EPCs) and damaged human umbilical vein endothelial cells (HUVECs) were assessed in vitro.Results The morphous,diameter,surface potential,concentration,and the antibody-binding rates of microbubbles were not statistically significant in MBIcAM-1,MBCD34,and MBD (P ＞0.05).Echo intensity in MBD significantly increased compared with MBICAM1,MBCD34,and MBiotin (P ＜ 0.01).The targeting experiment in vitro showed that the attachment rate of MBD to EPCs and damaged HUVECs significantly increased compared with MBiotin (P ＜0.01),while no remarkable difference in attachment rate was found between MBD and MBcD34 in EPCs,and between MBD and MBIcAM-1 in damaged HUVECs (P ＞0.05).Conclusions Dual-targeted microbubbles carrying both anti-CD34 monoclonal antibody and anti-ICAM-1 monoclonal antibody are prepared successfully.The study in vitro has proved that the dual-targeted microbubbles can specifically bind to both EPCs and damaged HUVECs.

OBJECTIVETo establish the quality standard of Entadae Semen, and provide scientific basis for its quality control.

METHODTLC and HPLC were used for qualitative identification and quantitative analysis of phaseoloidin and entadamide A-O-β-D-glucopyranoside in Entadae Semen. The test of water content, ash and ethanol-soluble extractives of Entadae Semen was carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition).

RESULTThe TLC was well separated with clear spots. The linear range of phaseoloidin was between 0.014 to 2.747 g x L(-1) (r = 0.999 6, n = 9) with an average recovery rate of 101.06% (RSD 0.90%, n = 6); the linear range of entadamide A-O-β-D-glucopyranoside was between 0.002 to 0.452 g x L(-1) (r = 0.999 7, n = 9) withan average recovery rate of 101.52% (RSD 1.09%, n = 6). The content of phaseoloidin in sample is between 5.12% to 9.24%, entadamide A-O-β-D-glucopyranoside is between 0.55% to 2.17%, alcohol-soluble extracts is between 30.9% to 45.2%, water is between 6.6% to 8.6%, and total ash is between 2.4% to 2.9%.

CONCLUSIONThe established standard is acceptable for quality control of Entadae Semen.

Objective To determine the serum level of pepsinogenⅠ,Ⅱ(PGⅠ,PGⅡ) and PGⅠ/Ⅱin the residents from Zhuanghe county,a high risk area of gastric cancer in North China,and to explore their distribution as well as related factors.Methods Serum PGⅠand PGⅡlevels were detec- ted with ELISA method in 6990 subjects.Gastric diseases were diagnosed by endoscopy and histopatho- logic examination.Serum H.pylori-IgG antibody was determined by ELISA method.Results The me- dian values for PGⅠ,PGⅡ,PGⅠ/Ⅱwere 86.9/?g/L,10.6/zg/L and 8.1 respectively.Serum PGⅠand PGⅡin male(95.2?g/L,12.1?g/L) were significantly higher than those in female(79.7?g/L, 9.4?g/L;P=0.000),PGⅠ/Ⅱratio(7.9) was significantly lower in male (8.3,P=0.000).There were significantly decrease in PGⅠ/Ⅱratio along with age increase.PGⅠ/Ⅱratio decreased signifi- cantly following with progression of gastric mucosa from normal (10.4) to non-atrophic lesions(8.8) and to atrophic lesions (6.6).Serum PGⅠand PGⅡin H. pylori positive subjects (88.7?g/L,11.4?g/L) were significantly higher than those in H.pylori negative subjects (81.4?g/L,8.4?g/L;P= 0.000),PGⅠ/Ⅱratio(7.7) was significantly lower in H.pylori positive subjects (9.6,P=0.000). For patients with atrophic lesions,the area under the PGⅠ/ⅡROC curve was 0.622.The best cut-off point for PGⅠ/Ⅱwas 6.9,with sensitivity of 53.2%,and specificity of 67.5%.Factors linked to PGⅠ/Ⅱwere identified using multinomial logistic regression:male (OR:1.151,95% CI:1.042—1.272, P=0.006),age=61(OR:1.358,95% CI:1.188—1.553,P=0.000),atrophic lesion(OR:2.075,95% CI:1.870—2.302,P=0.000),and H.pylori infection (OR:1.546,95% CI:1.368—1.748,P= 0.000).Conclusions The serum PG levels are significantly skewed from normal distrubition in the residents of Zhuanghe county,and affected by age and gender,as well as associated with gastric diseases and H.pylori in- fection.Compared with PGⅠand PGⅡalone,PGⅠ/Ⅱis more suitable for screening gastric cancer.
