| 2 | Hydrogen Sulfide Promotes Wheat Seed Germination and Alleviates Oxidative Damage against Copper Stress显示文摘With the enhancement of copper(Cu) stress,the germination percentage of wheat seeds decreased gradually. Pretreatment with sodium hydrosulfide(NaHS),hydrogen sulfide(H2S) donor alleviated the inhibitory effect of Cu stress in a dose-dependent manner; whereas little visible symptom was observed in germinating seeds and radicle tips cultured in NaHS solutions. It was verified that H2S or HS-rather than other sulfur-containing components derived from NaHS attribute to the potential role in promoting seed germination against Cu stress. Further studies showed that NaHS could promote amylase and esterase activities,reduce Cu-induced disturbance of plasma membrane integrity in the radicle tips,and sustain lower levels of malondialdehyde and H2O2 in germinating seeds. Furthermore,NaHS pretreatment increased activities of superoxide dismutase and catalase and decreased that of lipoxygenase,but showed no significant effect on ascorbate peroxidase. Alternatively,NaHS prevented uptake of Cu and promoted the accumulation of free amino acids in seeds exposed to Cu. In addition,a rapid accumulation of endogenous H2S in seeds was observed at the early stage of germination,and higher level of H2S in NaHS-pretreated seeds. These data indicated that H2S was involved in the mechanism of germinating seeds' responses to Cu stress. | Hua Zhang Lan-Ying Hu Kang-Di Hu Yun-Dong He Song-Hua Wang Jian-Ping Luo | 2008 | Journal of Integrative Plant Biology2008,50,12: | 93 |

| 6 | Analysis of in vivo patterns of caspase 3 gene expression in primary hepatocellular carcinoma and its relationship to p21^(WAF1) expression and hepatic apoptosis显示文摘AIM To detect the expression of caspase 3gene in primary human hepatocellular carcinoma(HCC)and investigate its relationship to p21WAF1gene expression and HCC apoptosis.METHODS In situ hybridization was employedto determine caspase 3 and p21WAF1expression inHCC.In situ end-labeling was used to detecthepatocytic apoptosis in HCC.RESULTS Twenty-one of 39(53.8%)cases ofHCC were found to express caspase 3transcripts,while 45.2% of HCC failed toexpress caspase 3.Non-cancerous adjacent livertissues showed more positive caspase 3(87.5%,7/8)as compared with HCC(P<0.05).The expression of caspase 3 is correlated withHCC differentiation,72.2%(13/18)ofmoderately to highly differentiated HCC showedcaspase 3 transcripts positive,while only 38.1%of poorly differentiated HCC harbored caspase 3transcripts(P<0.05).No relationship wasfound between caspase 3 expression and tumorsize or grade or metastasis,although 52.5%(5/8)of HCC with metastasis were caspase 3positive and a little higher than that with nometastasis(51.6%,P>0.05).Expression of caspase 3 alone did not affect the apoptosisindex(AI)of HCC.The AI was 7.12%o in caspase3-positive tumors(n=21),while in caspase 3-negative cases(n=18)6.59%0(P>0.05).Expression of caspase 3 clearly segregated withp21WAF1positive tumors as compared withp21WAF1-negative cases(16 of 23,69.6% versus5 of 16,31.3%)with statistical significance(P=0.017).In the cases with positive caspase 3and negative p21WAF1,the Al was found slightlyhigher,but with no statistical significance,thanthat with expression of p21WAF1and caspase 3(7.21‰ vs 6.98‰,P>0.05).CONCLUSION Loss of caspase 3 expressionmay contribute to HCC carcinogenesis,althoughthe expression of caspase 3 does not correlatewell with cell apoptosis in HCC.p21WAF1may bemerely one of the inhibitors which can reducecaspase 3 mediated cell apoptosis in HCCs. | Bao Hua Sun Jun Zhang Bao JǜWang Xi Ping Zhao You Kun Wang Zhi Qun Yu Dong Liang Yang Lian Jie Hao Department of Clinical Immunology,Tongji Hospital,Tongji Medical University,Wuhan 430030,Hubei Province,China | 2000 | World Journal of Gastroenterology2000,6,3: | 65 |
| 7 | Expression of vascular endothelial growth factor and its receptors KDR and Fit-1 in gastric cancer cells显示文摘AIM: The expression of vascular endothelial growth factor (VEGF) and its receptors KDR and Flt-1 by gastric carcinoma tissues and different gastric carcinoma cell lines was detected to elucidate the molecular mechanism of this growth factor in promoting tumor growth.METHODS: The expression of VEGF, Flt-1 and KDR was determined by reverse transcription-polymerase chain reaction (RT-PCR) in gastric cancer cell lines RF-1, RF-48,AGS-1, NCI-N87, NCI-SNU-1, NCI-SNU-5, NCI-SNU-16 and KATO-Ⅲ. The expression of Flt-1 and KDR in paraffinembedded specimens of gastric cancer was determined by immunohistochemistry. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to assess the role of VEGF in tumor cell proliferation.RESULTS: All 8 gastric cancer cell lines analyzed expressed VEGF121 and VEGF16s and six of them expressed both Flt-1 and KDR, while cell line NCI-SNU-5 expressed Flt-1 only and cell line KATOⅢ expressed neither Flt-1 nor KDR. The gastric carcinoma tissues expressed Flt-1 and KDR widely,with the positive rate of expression of Flt-1 and KDR being 84.6 % and 70 % respectively. The exogenous VEGF stimulated the growth of KDR-positive cell lines NCI-N87 and AGS-1 in a dose-dependent manner but exhibited no effect on the growth of KDR-negative cell line NCI-N87.CONCLUSION: VEGF and its receptors KDR and Flt-1 were expressed widely in gastric carcinoma cells and the VEGF stimulated KDR-positive tumor cell growth directly. These results suggest that VEGF may play a role in promoting tumor growth and metastasis by participating in both paracrine and autocrine pathways. | Hua Zhang Jian Wu Lin Meng Cheng-Chao Shou,Peking University School ofOncology,Beij ing Institute for Cancer Research,Beijing 100034,China | 2002 | World Journal of Gastroenterology2002,8,6: | 69 |
| 8 | Animal experiment and clinical study of effect of gamma-interferon on hepatic fibrosis显示文摘AIM To evaluate the antifibrotic effect ofdifferent doses of recombinant human Gamma-Interferon (IFN-γ) intwo rat models of hepaticfibrosis, and to observe its effect on moderatechronic hepatitis B virus fibrosis.METNODS Hepatic fibrosis was successfullyinduced in 150 and 196 rats by subcutaneousinjection of carbon tetrachloride (CCl4) andintraperitoneal injection of dimethylnitrosamine(DMN), respectively. Each of the two modeldose IFN-γ group (15 MU/kg per day, i.m. for 8group (1.67 MU/kg daily, i.m. for 8 weeks).Another group of 10 rats without any treatmentwas used as normal controls. At the end of theexperiment, semi-quantitative histopathologicalscores of inflammation and fibrosis, liver (αsmooth muscle actin (α-SMA) expression level,liver hydroxyl proline content and serumhyaluronic acid levels were compared. And 47medium chronic hepatitis B viral fibrosispatients were studied. They were given IFN-γtreatment, 100MU/day i.m. for the first threemonths and 100MU qod i.m. for the next sixmonths. Semi-quantitative pathological scoresof inflammation and fibrosis and serum hepaticfibrosis indices were compared within the 9months.RESULTS In animal experiment, thepathological fibrosis scores and liver hydroxylproline content were found to be significantlylower in rats treated with different doses of IFN-γ as compared with rats in fibrotic model groupinduced by either CCI4 or DMN, in a dose-dependent manner. For CCI4-induced model,pathological fibrosis scores in high, medium andIow doses IFN-γ groups were 5.10 ± 2.88, 7.70 ±3.53 and 8.00 ± 3.30, respectively, but the scorewas 14.60 ± 7.82 in fibrotic model group.Hydroxyl proline contents were 2.83 ± 1.18, 3.59± 1.22 and 4.80 ± 1.62, in the three IFN-γgroups, and 10.01 ± 3.23 in fibrotic model group.The difference was statistically significant(P<0.01). Similar results were found in DMN-induced model. Pathological fibrosis scoreswere 6.30±0.48, 8.10 ±2.72 and 8.30 ±2.58, inhigh, medium and Iow doses IFN-γ groups, and12.60 ± 3.57 in fibrotic model group. Hydroxylproline contents were 2.72 ± 0.58, 3.14 ± 0.71and 3.62 ± 1.02, in the three IFN-γ groups, and12.79 ± 1.54 in fibrotic model group. Thedifference was statistically significant(P<0.01). Serum hepatic fibrosis indicesdecreased significantly in the 47 patients afterIFN-γ treatment (HA: 433.38 ± 373.00 vs 281.57± 220.48; LN: 161.22± 41.02 vs 146.35 ± 44.67;PCⅢ: 192.59 ± 89.95 vs 156.98 ± 49.22; C-Ⅳ:156.30 ± 44.01 vs 139.14 ± 34.47) and thedifferences between the four indices weresignificant (P<0.05).

| 9 | Inhibition of signal transducer and activator of transcription 3 expression by RNA interference suppresses invasion through inducing anoikis in human colon cancer cells显示文摘AIM:To investigate the roles and mechanism of signal transducer and activator of transcription 3 (STAT3) in invasion of human colon cancer cells by RNA interference. METHODS: Small interfering RNA (siRNA) targeting Signal transducer and activator of transcription 3 (STAT3) was transfected into HT29 colon cancer cells. STAT3 protein level and DNA-binding activity of STAT3 was evaluated by western blotting and electrophoretic mobility shift assay (EMSA), respectively. We studied the anchorage-independent growth using colony formation in soft agar, and invasion using the boyden chamber model, anoikis using DNA fragmentation assay and terminal deoxynucleotidyltransferase-mediated dUTP nick-end labeling (TUNEL), respectively. Western blot assay was used to observe the protein expression of Bcl-xL and survivin in colon cancer HT29 cells. RESULTS: RNA interference (RNAi) mediated by siRNA leads to suppression of STAT3 expression in colon cancer cell lines. Suppression of STAT3 expression by siRNA could inhibit anchorage-independent growth, and invasion ability, and induces anoikis in the colon cancer cell line HT29. It has been shown that knockdown of STAT3 expression by siRNA results in a reduction in expression of Bcl-xL and survivin in HT29 cells. CONCLUSION: These results suggest that STAT3 siRNA can inhibit the invasion ability of colon cancer cells through inducing anoikis, which antiapoptotic genes survivin and Bcl-xL contribute to regulation of anoikis.These studies indicate STAT3 siRNA could be a useful therapeutic tool for the treatment of colon cancer. | Yu Fan You-Li Zhang Ying Wu Wei Zhang Yin-Huan Wang Zhao-Ming Cheng Hua Li | 2008 | World Journal of Gastroenterology2008,14,3: | 51 |
| 10 | Hydrogen Sulfide Promotes Root Organogenesis in Ipomoea batatas, Salix matsudana and Glycine max显示文摘In this report, we demonstrate that sodium hydrosulfide (NaHS), a hydrogen sulfide (H2S) donor, promoted adventitious root formation mediated by auxin and nitric oxide (NO). Application of the H2S donor to seedling cuttings of sweet potato (Ipomoea batatas L.) promoted the number and length of adventitious roots in a dose-dependent manner. It was also verified that H2S or HS- rather than other sulfur-containing components derived from NaHS could be attributed to the stimulation of adventitious root formation. A rapid increase in endogenous H2S, indole acetic acid (IAA) and NO were sequentially observed in shoot tips of sweet potato seedlings treated with HaHS. Further investigation showed that H2S-mediated root formation was alleviated by N-1-naphthylphthalamic acid (NPA), an IAA transport inhibitor, and 2-(4-carboxyphenyl)- 4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), an NO scavenger. Similar phenomena in H2S donor-dependent root organogenesis were observed in both excised willow (Salix matsudana var. tortuosa Vilm) shoots and soybean (Glycine max L.) seedlings. These results indicated that the process of H2S-induced adventitious root formation was likely mediated by IAA and NO, and that H2S acts upstream of IAA and NO signal transduction pathways. | Hua Zhang Jun Tang Xiao-Ping Liu Yun Wang Wei Yu Wei-Yan Peng Fang Fang Dai-Fu Ma Zhao-Jun Wei Lan-Ying Hu | 2009 | Journal of Integrative Plant Biology2009,51,12: | 58 |

| 13 | Moxibustion inhibits interleukin-12 and tumor necrosis factor alpha and modulates intestinal flora in rat with ulcerative colitis显示文摘AIM: To investigate the effect of moxibustion on intestinal flora and release of interleukin-12 (IL-12) and tumor necrosis factor-α (TNF-α) from the colon in rat with ulcerative colitis (UC). METHODS: A rat model of UC was established by local stimulation of the intestine with supernatant from colonic contents harvested from human UC patients. A total of 40 male Sprague-Dawley rats were randomly divided into the following groups: normal (sham), model (UC), herb-partition moxibustion (HPM-treated), and positive control sulfasalazine (SA-treated). Rats treated with HPM received HPM at acupuncture points ST25 and RN6, once a day for 15 min, for a total of 8 d. Rats in the SA group were perfused with SA twice a day for 8 d. The colonic histopathology was observed by hematoxylin-eosin. The levels of intestinal flora, including Bifidobacterium, Lactobacillus, Escherichia coli (E. coli), and Bacteroides fragilis (B. fragilis), were tested by real-time quantitative polymerase chain reaction to detect bacterial 16S rRNA/DNA in order to determine DNA copy numbers of each specific species. Immunohistochemical assays were used to observe the expression of TNF-α and IL-12 in the rat colons. RESULTS: HPM treatment inhibited immunopathology in colonic tissues of UC rats; the general morphological score and the immunopathological score were significantly decreased in the HPM and SA groups compared with the model group [3.5 (2.0-4.0), 3.0 (1.5-3.5) vs 6.0 (5.5-7.0), P < 0.05 for the general morphological score, and 3.00 (2.00-3.50), 3.00 (2.50-3.50) vs 5.00 (4.50-5.50), P < 0.01 for the immunopathological score]. As measured by DNA copy number, we found that Bifidobacterium and Lactobacillus, which are associated with a healthy colon, were significantly higher in the HPM and SA groups than in the model group (1.395 ± 1.339, 1.461 ± 1.152 vs 0.045 ± 0.036, P < 0.01 for Bifidobacterium, and 0.395 ± 0.325, 0.851 ± 0.651 vs 0.0015 ± 0.0014, P < 0.01 for Lactobacillus). On the other hand, E. coli and B. fragilis, which are associated with an inflamed colon, were significantly lower in the HPM and SA groups than in the model group (0.244 ± 0.107, 0.628 ± 0.257 vs 1.691 ± 0.683, P < 0.01 for E. coli, and 0.351 ± 0.181, 0.416 ± 0.329 vs 1.285 ± 1.039, P < 0.01 for B. fragilis). The expression of TNF-α and IL-12 was decreased after HPM and SA treatment as compared to UC model alone (4970.81 ± 959.78, 6635.45 ± 1135.16 vs 12333.81 ± 680.79, P < 0.01 for TNF-α, and 5528.75 ± 1245.72, 7477.38 ± 1259.16 vs 12550.29 ± 1973.30, P < 0.01 for IL-12). CONCLUSION: HPM treatment can regulate intestinal flora and inhibit the expression of TNF-α and IL-12 in the colon tissues of UC rats, indicating that HPM can improve colonic immune response. | Xiao-Mei Wang Yuan Lu Lu-Yi Wu Shu-Guang Yu Bai-Xiao Zhao Hong-Yi Hu Huan-Gan Wu Chun-Hui Bao Hui-Rong Liu Jin-Hai Wang Yi Yao Xue-Gui Hua Hui-Ying Guo Li-Rong Shen | 2012 | World Journal of Gastroenterology2012,18,46: | 57 |

| 17 | Apoptosis,proliferation and p53 gene expression of H.pylori associated gastric epithelial lesions显示文摘AIM: To study the relationship between Helicobacter pylori (H. Pylori) and gastric carcinoma and its possible pathogenesis by H. Pylori.METHODS: DNEL technique and immunohistochemical technique were used to study the state of apoptosis,proliferation and p53 gene expression. A total of 100 gastric mucosal biopsy specimens, including 20 normal mucosa, 30H. Pylori-negative and 30 H. Pylorf-positive gastric precancerous lesions along with 20 gastric carcinomas were studied.RESULTS: There were several apoptotic cells in the superficial epithelium and a few proliferative cells within the neck of gastric glands, and no p53 protein expression in normal mucosa. In gastric carcinoma, there were few apoptotic cells, while there were a large number of proliferative cells, and expression of p53 protein significantly was increased. In the phase of metaplasia, the apoptotic index (Al, 4.36% ± 1.95%), proliferative index (PI, 19.11% ± 6.79%) and positivity of p53 expression (46.7%) in H. Pylori-positive group were higher than those in normal mucosa (P< 0.01). Al in H. Pylori-positive group was higher than that in H. Pylori-negative group (3.81% ±1.76%), PI in H. Pylori-positive group was higher than that in H. Pylori-negative group (12.25% ±5.63%, P<0.01 ). In the phase of dysplasia, Al (2.31% ± 1.10%) in H. Pylori-positive group was lower (3.05% ± 1.29%) than that in H. Pylori-negative group, but PI (33.89% ± 11.65%)wassignificantly higher(22.09± 8018%, P< 0.01). In phases of metaplasia, dysplasia and gastric cancer in the H. Pylori-positive group, Als had an evidently graduall decreasing trend (P < 0.01 ), while Pis had an evidently gradual increasing trend (P< 0.05 or P< 0.01), and there was also a trend of gradual increase in the expression of p53 gene.CONCLUSION: In the course of the formation of gastric carcinoma, proliferation of gastric mucosa can be greatly increased by H. Pylori, and H. Pylori can induce apoptosis in the phase of metaplasia but in the phase of dysplasia H.pylori can inhibit cellular apoptosis. And H. Pylori infection can strengthen the expression of mutated p53 gene. | Zhong Zhang~1 Yuan Yuan Hua Gao Ming Dong Lan Wang Yue-Hua Gong 1 Department of Pathology,Shenyang Medical College,Shenyang 110031 Liaoning Province,China | 2001 | World Journal of Gastroenterology2001,7,6: | 46 |
| 18 | Study of the mechanisms of acupuncture and moxibustion treatmentfor ulcerative colitis ratsinview of the gene expression of cytokines显示文摘AIM To observe the effect of acupuncture and moxibustion on the expression of IL 1β and IL 6 mRNA in ulcerative colitis rats. METHODS The SD rat ulcerative colitis model was created by immunological method associated with local stimulation. Colonic mucosa was prepared from human fresh surgical colonic specimens, homogenized by adding appropriate amount of normal saline and centrifuged at 3000*!r/*!min . The supernatant was collected for measurement of protein conentration and then mixed with Freund adjuvant. This antigen fluid was first injected into the plantae of the model group rats, and then into their plantae, dorsa, inguina and abdominal cavities (no Freund adjuvant for the last injection) again on the 10th, 17th, 24th and 31st day. When a certain titer of serum anti colonic antibody was reached, 2% formalin and antigen fluid (no Freund adjuvant) were administered separately by enema. The ulcerative colitis rat model was thus set up. The animals were randomly divided into four groups: model control group (MC, n =8), electro acupuncture group (EA, n =8), herbs partition moxibustion group (HPM 8), normal control group (NC, n =8). HPM: Moxa cones made of refined mugwort floss were placed on the medicinal pad (medicinal pad dispensing: Radix Aconiti praeparata, cortex Cinnamomi, etc ) for Qihai (RN 6) and Tianshu (ST 25, bilateral) and ignited. Two moxa cones were used for each acupoint once a day and 14 times in all. EA: Tianshu (bilateral) and Qihai were stimulated by the intermittent pulse with 2Hz frequency, 4mA intensity for 20 minutes once a day and 14 times in all. After treatment, rats of all four groups were killed simultaneously. The spleen was separated and the distal colon was dissected. Total tissue RNA was isolated by the guanidinium thiocyanate phenol chloroform extraction method. RT PCR technique was used to study the expression of IL 1β and IL 6 mRNA. RESULTS IL 1β and IL 6 mRNAs were not detected in the spleen and colonic mucosa of the NC rats, whereas they were significantly expressed in that of the MC rats. IL 1β and IL 6 mRNAs were markedly lower in the EA and HPM rats than that in MC rats. There was no significant difference between the levels of IL 1β and IL 6 mRNAs in the EA and HPM rats. The expressions of IL 1β and IL 6 mRNAs were nearly the same in the spleen and colon of all groups. CONCLUSION Acupuncture and moxibustion greatly inhibited the expression of IL 1β and IL 6 mRNA in the experimental ulcerative colitis rats. | Wu HG Zhou LB Pan YY Huang C Chen HP Shi Z Hua XG | 1999 | World Journal of Gastroenterology1999,5,6: | 45 |
