Objective To study the correlation between small intestinal bacterial overgrowth (SIBO) and plasma endotoxin,platelet-derived growth factor(PDGF)level,and levels of serum hyaluronic acid (HA),laminin(LN),N-terminal procollagen Ⅲ peptide(PⅢNP)and type Ⅳ collagen(Ⅳ.C). Methods Lactulose hydrogen breath test (LHBT) was performed in 64 patients with chronic liver disease. Plasma endotoxin was measured with Limulus test, plasma PDGF was tested with ABC-enzyme-linked immunosorbent assay,serum HA,LN,PⅢNP and Ⅳ.C were tested by radioimmunoassay(RIA) in the patients. The relationship between SIBO and plasma endotoxin, PDGF and HA,LN,PⅢNP and Ⅳ.C levels were analyzed. Results Positive LHBT suggesting the existence of SIBO were observed in 22 patients(34.4%). Plasma endotoxin[(62?19) pg/ml vs.(31?13) pg/ml] and PDGF [(211?77) pg/ml vs.(136?57) pg/ml] levels were significantly higher in patients with SIBO than those in patients without SIBO (P

Objective To evaluate the diagnostic value, patients' tolerance and complications of double-balloon enteroscopy (DBE) in the diagnosis of small intestinal diseases. Methods During May 2003 to July 2005, a total of 68 patients (36 men, 32 women; mean age of 52. 6 years, range 15-78 years) with suspected small intestinal diseases were performed double-balloon enteroscopy (36 via mouth, 25 via anus and 7 via both mouth and anus according to suspected lesion location). Among them, obscure recurrent gastrointestinal bleeding was found in 39 cases, incomplete small intestinal obstruction in 7 cases, chronic abdominal pain in 14 cases, and chronic diarrhea in 8 cases. Results Approximately one half to three-fourth of the entire small intestine was observed by each approach in all cases except for 3 cases of severe intestinal stricture. The observation of the whole small intestine was finished by the combination of both oral and anal approaches in 7 cases. The appropriate use of X-ray made the enteroscopy easier and more helpful to determine the extent and location of the lesions. The lesions were found in 41 of the 68 patients, with a total positive rate of 60. 3%. The diagnostics yields was 26/39(62. 6%) in obscure recurrent gastrointestinal bleeding, 5 in incomplete intestinal obstruction, 6/14(43%) in chronic abdominal pain and 4 in chronic diarrhea, respectively. Fifty-seven cases (83. 8%) tolerated well without anesthesia while 11 cases received propofol anesthesia. No procedure-related severe adverse events or severe complications such as hemorrhage or perforation occurred in all cases. Conclusion Double-balloon enteroscopy is a well-tolerated and safe diagnostic approach with a high diagnostic yield in small intestinal diseases.

Objective To investigate the effect of H.pylori infection and eradication on gastric parietal cell and H + K +ATPase mRNA expression in a murine model. Methods Twenty 7 week old SPF BALB/C mice (10 males and 10 females) each were fed by H.pylori strain (Sydney Strain 1,SS1) at a dose of 0.4 ml (10 9CFU) per day for consecutive 5 days. Two months after infection of H. pylori, all mice were divided into two groups, the eradication group (10 mice) and the infection group (10 mice). Mice in the eradication group were administered clarithromycin ( 13.5 mg?kg -1 ?d -1 ) twice per day for one week (one mouse was died).Meanwhile, mice in the infection group were given the same amount placebo. All mice were killed at one month after the administration.The gastric mucosa was removed for rapid urease testing (RUT) and Giemsa stainning. The expression of H + K +ATPase mRNA was detected by RT PCR. Morphological changes in parietal cells were assessed by electron microscope. Results The animals in infection group were 100% infected by H.pylori, and RUT and Giemsa staining were all positive. Meanwhile , all but one mouse in the eradcation group were negative to RUT and Giemsa staining. In the infection group, the average ratio A C to A T (A C means the area of the canaliculi, A T means the area of the parietal cells ) was ( 2.20 ? 0.06 )/10 4, significant lower than that in the eradication group [(3.20 ? 0.06 )/10 4, P

OBJECTIVE To investigate the effect of quercetin on primary cultured newborn rat cortex neuron cell which is estrogen depletion, and discuss the possible mechanism, to provide new ideas and strategies for developing a drug of neurodegenerative disease. METHODS Rat cortex neurons were isolated from one day old Sprague Dawley rats and treated with estrogen, quercetin and estrogen receptor antagonists (ICI182,780). Cell viability was determined by MTT assay, neurite outgrowth was measured by fluorescent microsope and estrogen receptors were determine by Western blot. RESULTS Quercetin functions like estrogen to increase cortex neuronal cell viability, the Que (50, 100 μmol·L-1) group compared with the control group could significantly improve the activity of the cortical neurons(P<0.05). It can also increase neurite out growth, the Que (50,100 μmol·L-1) group significantly promoted the formation of synapse, most of the neurons were full, and the synapses of neurons became thick, growth, and connect to a dense neural network. And in the Western blot experiments, Que (50, 100 μmol·L-1) group could obviously increase the expression of estrogen receptor alpha protein, in addition, the neural protective effect of quercetin can be inhibited by ICI182,780. CONCLUSION Quercetin like estrogen can protected cortex neuronal and the effect of quercetin on cortex neuronal cells was mediated by estrogen receptor alpha.

Objective To evaluate the role of interleukin-4 receptor (IL-4R) in renal fibrosis following renal ischemia-reperfusion (I/R) injury in mice.Methods Twelve male wild type BALB/C mice and 12 IL-4Rα gene-knockout mice,aged 8-10 weeks,weighing 20-30 g,were used in the study.The mice of either type were divided into 2 groups (n =6 each) using a random number table:sham operation group (group S) and group I/R.In group I/R,renal I/R was induced by occlusion of the right renal artery for 1 h with atraumatic microclips followed by 2 weeks of reperfusion.The right renal artery was only isolated in group S.At 2 weeks of reperfusion,blood samples were taken from the orbital vein for determination of the concentrations of serum blood urea nitrogen (BUN) and creatinine (Cr).The renal tissues were obtained,and the renal fibrosis area was measured by Sirius Red staining.The expression of fibronectin (FN),collagen Ⅰ (COL-Ⅰ) and α-smooth muscle actin (α-SMA) in renal tissues was detected by immunofluorescence.The expression of signal transducer and activator of transcription 6 (STAT6) and phospho-STAT6 in renal tissues was determined by Western blot.The ratio of phoshop-STAT6 to STAT6 was calculated to reflect the phosphorylation of STAT6.Results Compared with group S of wild type mice,the serum BUN and Cr concentrations and renal fibrosis area were significantly increased,the expression of FN,COL-Ⅰ and α-SMA in renal tissues was significantly up-regulated,and the phosphorylation of STAT6 in renal tissues was significantly increased in group I/R of wild type and IL-4Rα KO mice (P＜0.05).Compared with group I/R of wild type mice,the serum BUN and Cr concentrations and renal fibrosis area were significantly decreased,the expression of FN,COL-Ⅰ and α-SMA in renal tissues was significantly down-regulated,and the phosphorylation of STAT6 in renal tissues was significantly decreased in group I/R of IL-4RαKO mice (P＜0.05).Conclusion The mechanism of renal fibrosis following renal I/R injury is partially related to IL-4R,and IL-4R results in renal fibrosis through promoting activation of STAT6 signaling pathway in mice.
