2Early intrajejunal nutrition: bacterial translocation and gut barrier function of severe acute pancreatitis in dogs显示文摘Objective: To evaluate the effect of early intrajejunalnutrition in attenuating bacterial and/or endotoxintranslocation and improving gut barrier function ofsevere acute pancreatitis (SAP) in dogs.Methods: 15 dogs were divided into parenteral nutrition(PN) group(7 dogs)and early intrajejunal nutrition(EIN) group(8). EIN was delivered nutrients via a nee-dle jejunostomy catheter feeding at 48h after operation.SAP model was induced by injecting 1 ml/kg of com-bined solution of 5% sodium taurocholate and 8000-10000 BAEE units trypsin/ml into the pancreas via thepancreatic duct. Systemic blood samples were ob-tained before and 1, 3, 5, 7 d following SAP, and culturedby aerobic as well as anaerobic bacterial growth. Systemicplasma and portal vein endotoxin levels were quantifiedby the chromogenic limulus amebocyte lysate (LAL)technique. Portal vein blood and specimens of tissuefrom the mesenteriolum and mesocolon lymph nodes,lung, pulmonary portal lymph nodes, pancreatitis tissueand periopancreas tissue were adopted before the experi-ment was finished. Aliquots of the homogenata were cul-tured as blood mentioned above to determine the magnitudeof the bacteria DNA, protein and the villi, the thickness ofmucosa, and the whole bowel wall of the ileum and trans-verse colon were measured.Results: The study showed that the levels of systemicplasma endotoxin and the magnitude of bacterialtranslocation to the portal and systemic blood and dis-tant organ were reduced significantly in the EINgroup as compared with the TPN group. The contentsof protein and DNA, the height of villi, the thicknessof mucosa and whole bowel wall of the ileum andtransverse colon in the EIN group were higher thanthose in the PN group.Conclusion: Our results suggested that EIN is safe andeffective to be adopted by intrajejunal delivery of nu-trients in SAP, decreases the occurrence of gut bacterialtranslocation, and improves the gut barrier function.Huan-Long Qin Zhen-Dong Su Qi Gao Qing-Tian Lin From the Department of Surgery, Shanghai Sixth People’s Hospital, Shanghai, 200233, China 2002Hepatobiliary & Pancreatic Diseases International2002,1,1:20
3Symmetric-key cryptosystem with DNA technology显示文摘DNA cryptography is a new field which has emerged with progress in the research of DNA computing. In our study, a symmetric-key cryptosystem was designed by applying a modern DNA biotechnology, microarray, into cryptographic technologies. This is referred to as DNA symmetric-key cryptosystem (DNASC). In DNASC, both encryption and decryption keys are formed by DNA probes, while its ciphertext is embedded in a specially designed DNA chip (microarray). The security of this system is mainly rooted in difficult biology processes and problems, rather than conventional computing technology, thus it is unaffected by changes from the attack of the coming quantum computer. The encryption process is a fabrication of a specially designed DNA chip and the decryption process is the DNA hybridization. In DNASC, billions of DNA probes are hybridized and identified at the same time, thus the decryption process is conducted in a massive, parallel way. The great potential in vast parallelism computation and the extraordinary information density of DNA are displayed in DNASC to some degree.LU MingXin1,2*, LAI XueJia3*, XIAO GuoZhen4,2 & QIN Lei5 1 Department of Information Management, Nanjing University, Nanjing 210093, China 2 State Key Lab of Information Security, Institute of Software of Chinese Academy of Science, Beijing 100049, China 3 Department of Computer Science & Engineer, Shanghai Jiao Tong University, Shanghai 200030, China 4 State Key Lab of ISN, Xidian University, Xi’an 710071, China 5 Cancer Research Institute, Queen’s University, Kingston, Ontario, K7L3N6, Canada 2007Science in China(Series F)2007,50,3:14

5Factors predicting survival in patients with proximal gastric carcinoma involving the esophagus显示文摘AIM:To investigate the clinicopathologic features which predict surgical overall survival in patients with proximal gastric carcinoma involving the esophagus (PGCE).METHODS:Electronic pathology database established in the Department of Pathology of the Nanjing Drum Tower Hospital was searched for consecutive resection cases of proximal gastric carcinoma over the period from May 2004 through July 2009.Each retrieved pathology report was reviewed and the cases with tumors crossing the gastroesophageal junction line were selected as PGCE.Each tumor was re-staged,following the guidelines on esophageal adenocarcinoma,according to the 7th edition of the American Joint Commission on Cancer Staging Manual.All histology slides were studied along with the pathology report for a retrospective analysis of 13 clinicopathologic features,i.e.,age,gender,Helicobacter pylori (H.pylori ) infection,surgical modality,Siewert type,tumor Bormann's type,size,differentiation,histology type,surgical margin,lymphovascular and perineural invasion,and pathologic stage in relation to survival after surgical resection.Prognostic factors for overall survival were assessed with uniand multi-variate analyses.RESULTS:Patients' mean age was 65 years (range:47-90 years).The male:female ratio was 3.3.The 1-,3and 5-year overall survival rates were 87%,61% and 32%,respectively.By univariate analysis,age,male gender,H.pylori ,tumor Bormann's type,size,histology type,surgical modality,positive surgical margin,lymphovascular invasion,and pT stage were not predictive for overall survival;in contrast,perineural invasion (P = 0.003),poor differentiation (P = 0.0003),> 15 total lymph nodes retrieved (P = 0.008),positive lymph nodes (P = 0.001),and distant metastasis (P = 0.005) predicted poor post-operative overall survival.Celiac axis nodal metastasis was associated with significantly worse overall survival (P = 0.007).By multivariate analysis,≥ 16 positive nodes (P = 0.018),lymph node ratio > 0.2 (P = 0.003),and overall pathologic stage (P = 0.002) were independent predictors for poor overall survival after resection.CONCLUSION:Patients with PGCE showed worse overall survival in elderly,high nodal burden and advanced pathologic stage.This cancer may be more accurately staged as gastric,than esophageal,cancer.Yi-Fen Zhang Jiong Shi Hui-Ping Yu An-Ning Feng Xiang-Shan Fan Gregory Y Lauwers Hiroshi Mashimo Jason S Gold Gang Chen Qin Huang 2012World Journal of Gastroenterology2012,18,27:12

7Effects of Dan-Shao-Hua-Xian on the expression of collagen type I and III in rats with hepatic fibrosis显示文摘BACKGROUND: Hepatic fibrosis is the common patholo gical change in various chronic liver diseases,and its major cause is the imbalance between the production and degra dation of the extracellular matrix, which is mainly com posed of collagens. Dan-Shao-Hua-Xian ( DSHX) cap sule, a traditional Chinese herbal compound, has shown marked preventive effects on hepatic fibrosis in rats in our previous studies. The present study was designed to further investigate its therapeutic actions on hepatic fibrosis in rats and its possible mechanisms. METHODS: Eighty male Wistar rats were randomly divid- ed into normal control group, hepatic fibrosis group, non DSHX-treated group, low-dose-treated group, and high dose-treated group. The rat models of hepatic fibrosis were established by subcutaneous injecton of CC14 , drinking al- cohol , giving diet of hyperliprosis and hypoprotein for 8 weeks. The two DSHX-treated groups were treated respec- tively with low dose (0.5 g/kg) and high dose (1.0 g/kg) of DSHX capsule p. o. everyday for 8 weeks. At the end of the experiment, liver indexes were calculated in each group in addition to the levels of the serum hyaluronic acid and alanine aminotransferase. Their degree of hepatic fibrosis and urinary excretion of hydroxyproline and expression of collagen , were detected. RESULTS: Comparison of the indexes of the hepatic fibro- sis group and non-DSHX-treated group revealed that the liver indexes, levels of serum hyaluronic acid and alanine aminotransferase, and stage of hepatic fibrosis were all sig- nificantly reduced in the two DSHX treated groups. The urinary excretion of hydroxyproline was increased and the expression of collagen I and HI in liver tissue was lessened. These alterations were more obviously observed in the high-dose-treated group. CONCLUSION: DSHX capsule has certain therapeutic effect on hepatic fibrosis in rats.Xiao-Xia Geng, Qin Yang, Ru-Jia Xie, Xin-Hua Luo, Cheng-Xiu Li and Ming-Liang Cheng Guizhou, China Department of Infectious Diseases, Affiliated Hospital of Guiyang Medical College Department of Pathophysiology, Guiyang Medical College Depart- ment of Infectious Diseases, People’ s Hospital of Guizhou Province and Department of Pharmacology, Guiyang Medical College 2004Hepatobiliary & Pancreatic Diseases International2004,3,4:4
8Molecular and Epidemiological Characterization of Infant Botulism in Beijing, China显示文摘Laboratory-based pathogen isolation, identification, and toxicity determination were performed on samples from a suspected case of infant botulism. Mice injected with cultures generated from the enema sample and ingested Powered infant formula(PIF) presented typical signs of botulism. Antitoxins to polyvalent botulinum neurotoxins(BoNTs) and monovalent BoNT type B antitoxin had protective effects. Clostridium botulinum isolated from the enema and residual PIF samples were positive for type B toxin. Pulsed-field gel electrophoresis(PFGE) revealed that the two strains of C. botulinum isolated from the two samples produced indistinguishable pulsotypes. These findings confirmed this case of type B infant botulism associated with the ingestion of PIF contaminated by type B C. botulinum spores.DONG Yin Ping WANG Wei JIANG Tao XU Jin HAN Chun Hui YAN Shao Fei Séamus Fanning LI Ying MA Xiao Chen ZHANG Di ZHAO Yao ZENG Biao LI Feng Qin 2017Biomedical and Environmental Sciences2017,30,6:4

10Common non-synonymous polymorphisms in the BRCA1 Associated RING Domain (BARD1) gene are associated with breast cancer susceptibility:a case-control analysis显示文摘The BRCA1 Associated RING Domain(BARD1) gene has been identified as a high penetrance gene for breast cancer, whose germline and somatic mutations were reported in both non-BRCA1/2 hereditary site-specific and sporadic breast cancer cases. BARD1 plays a crucial role in tumor repression, along with its heterodimeric partner BRCA1. In the current study, we tested the hypothesis that common non-synonymous polymorphisms in BARD1 are associated with breast cancer susceptibility in a case-control study of 507 patients with incident breast cancer and 539 frequency-matched cancer-free controls in Chinese women. We genotyped all three common(minor allele frequency (MAF) > 0.10) non-synonymous polymorphisms(Pro24Ser, Arg378Ser, and Val507Met) in BARD1. We found that the BARD1 Pro24Ser variant genotypes(24Pro/Ser and 24Ser/Ser) and Arg378Ser variant homozygote 378Ser/Ser were associated with a significantly decreased breast cancer risk, compared with their wild-type homozygotes, respectively. Furthermore, a significant locus-locus interaction was evident between Pro24Ser and Arg378Ser (P-int = 0.032). Among the 378Ser variant allele carriers, the 24Pro/Pro wild-type homozygote was associated with a significantly increased breast cancer risk (adjusted OR = 1.81, 95% CI = 1.11-2.95), but the subjects having 24Pro/Ser or Ser/Ser variant genotypes had a significantly decreased risk(adjusted OR = 0.74, 95% CI = 0.56-0.99). In stratified analysis, this locus-locus interaction was more evident among subjects without family cancer history, those with positive estrogen receptor (ER) and individuals with negative progesterone receptor(PR). These findings indicate that the potentially functional polymorphisms Pro24Ser and Arg378Ser in BARD1 may jointly contribute to the susceptibility of breast cancer.Huo, X Hu, Z. B Zhai, X.

12The reconstruction and interpretations of lake status at 6 ka and 18 ka B.P.in inland mainland Asia显示文摘By means of survey of literature through compilations of sedimentological, biogeological and geomorphologic data, the inland lake level changes in arid or semi arid mainland Asia at 6 and 18 ka B.P. have been reconstructed. The results showed that the lakes from western and northwestern Asia were characterized by very high water levels at 18 ka B.P., but low or intermediate water stands at 6 ka B.P. The high lake level in this region was associated with the southward displacement of westerlies, therefore, the extent of the high lake stand indicated the southern flank of westerlies during the glaciation. Conversely, the lakes from the eastern and southern Asia registered comparative low levels at 18 ka B.P. and significantly high one at 6 ka B.P. The lowering of lake level at 18 ka B.P. was caused by the weakened summer monsoon and the high lake level at 6 ka B.P. by the enhanced summer monsoon induced by the enlarged thermal contrast between land and ocean. The extent of high lake levels indicated the northern boundary of monsoon expansion. Between the above two regions, there is a climatic transitional zone in the Central Asia where the lake behavior was close to that in southeastern Asia at 6 ka B.P. but became similar to that in northwestern Asia at 18 ka B.P. Thus this zone became a transitional sector from the monsoon to the westerlies.QIN Boqiang 1, SHI Yafeng 1 and YU Ge 2, 3 1.

13Parenteral versus early intrajejunal nutrition:Effect on pancreatitic natural course,entero-hormones release and its efficacy on dogs with acute pancreatitis显示文摘AIM: To evaluate the effect of early intrajejunal nutrition (EIN) on the natural course, entero-hormone secretion and its efficacy on dogs with acute pancreatitis.METHODS: An acute pancreatitis model was induced by injecting 1 ml/kg of combined solution (2.5% sodium taurocholate and 8 000-10 000 BAEE units trypsin/mi) into the pancreas via pancreatic duct. Fifteen dogs were divided into parenteral nutrition (PN) group and EIN group. Two groups were isonitrogenous and isocaloric. EIN was used at postoperative 24 h. Serum glucose, calcium, amylase and lysosomal enzymes were determined before and 1, 4, 7 d after acute pancreatitis was induced. All the dogs were injected 50 uCi 125I-BSA 4 h before sacrificed on the 7th day.The 125I -BSA index of the pancreas/muscle, pancreas/blood,and pancreas pathology score (PPS) were determined. The peripheral plasma cholecystokinin (CCK), secretin (SEC) and gastrin were measured by ELISA and RIA, and was quantitative analysis of pancreatic juice and amylase,pancreatolipase and HCO3-, Cl-, Na+ and K+ performed by an autochemical analyzer at 30, 60, 120 and 180 min after beginning PN or EIN on the first day.RESULTS: There was no difference between two groups in the contents of serum calcium, amylase and lysosomal enzymes, 125I-BSA index of pancreas/muscle and pancreas/blood and PPS. The contents of CCK and gastrin in EIN were higher than those in PN group at 60 and 120 min (P<0.05).The content of SEC post-infusion of nutrition solution was higher than that of pre-infusion of nutrition solution in both groups, and only at 60 min SEC in EIN group was higher than that in PN group. The content of gastrin in EIN was higher than that in PN group at 120 and 180 min (P<0.05).The changes of pancreatic juice, amylase, pancreatolipase and HCO3-, Cl-, Na+ and K+ between two groups did not reach significantly statistical difference (P>0.05).CONCLUSION: EIN does not stimulate entero-hormone and pancreatic juice secretion, and enzyme-protein synthesis and release. EIN has no effect on the natural course of acute pancreatitis.Huan-Long Qin Zhen-Dong Su Lei-Guang Hu Zai-Xian Ding Qing-Tian Lin, Department of Surgery, Sixth People’s Hospital, Shanghai Jiaotong University Shanghai 200233, China 2003World Journal of Gastroenterology2003,9,10:2
