ObjectiveTo investigate the complication and nursing of intestines nutrition in critical patients after operation. MethodsThe clinical states of 40 patients after operation and being brought to ICU were analyzed.ResultsPatients accepting intestines nutrition presented high incidence of gastrointestinal complications. ConclusionIt is important to pay attention to prevent gastrointestinal complications in patients accepting intestines nutrition early postoperation.

Objective To investigate the effects of sodium butyrate (SB) on fetal gastric epithelial cells (GECs) in vitro damaged by N-methyl-N’-nitro-N-nitrosoguanidine (MNNG). Methods The fetal gastric epithelial cells were isolated, cultured and identified. Then the cells of the second generation were cocultured with 10 -5 mol/L, 10 -6 mol/L, 10 -7 mol/L SB for 4 h, then added with 10 -5 mol/L MNNG culturing for another 24 h. After the treated cells were finally cultured in normal culture medium for 40 d, the unscheduled DNA synthesis (UDS), lipid peroxidation (LPO) and ras p21 were detected. The cells were only cultured with 10 -5 mol/L MNNG served as negative control and without MNNG or SB as normal control. Results The level of UDS, the contents of lipid peroxidation products and the concentrations of ras p21 in GECs treated with 10 -5 mol/L and 10 -6 mol/L SB decreased obviously, and had significant differences with that of GECs treated without SB. Conclusion SB can effectively prevent the damage of GECs induced from MNNG.

Purpose:To study the changes of t-PA ?u-PA expression and fibrinolysis molecular mark ers in patients with gastric or intestinal cancer in order to elucidate their cl inical significance. Methods:The plasma levels of t-PA ?u-PA ?u-PAR and PAP were measured by ELISA . Gen e transcription of t-PA?u-PA mRNA were detected by Real-time RT-PCR. Results:The plasma levels of u-PA?u-PAR and PAP were elevated in gastric or intestina l cancer patients ,while u-PA was markedly elevated in patients with local infi ltration?lymph node involvement or distal metastasis. u-PA mRNA was higher and t-PA was lower in gastric or intestinal cancer compared to normal tissue. Conclusions:Hyperfibrinolysis was an important factor related with m etastasis potential of gastric or intestinal cancer. t-PA may be a character of well differentiated tissue.

Objective:To construct eukaryotic expressing vector of the full length coding sequence of Bad gene and to express the gene in the basal cell carcinima A431 cells.Methods:Bad gene was amplified from Hela cell line by RT-PCR and the fragment of the cDNA was cloned into eukaryotic expressing vector pcDNA3.1-myc by ligating the fragment into XhoI and EcoRI site.The recombinant plasmid pcDNA3.1-myc-Bad was identified by DNA sequencing and restriction enzyme analysis.The gene transfection mediated by lipofectin was used to introduce the eukaryotic expressing vector of pcDNA3.1-myc-Bad into human basal cell carcinima A431 cells. After selection with G418, resistant colonies were obtained.Trasfection efficiency was identified by Western blot and SABC-FITC assay.Cell proliferation was examined by cell counting and colonogenic assay after transfection.Results:A 500 bp DNA fragment was amplified with RT-PCR.Sequence and restriction enzyme analysis showed that the recombinant plasmid pcDNA3.1-myc-Bad was constructed successfully.In human basal cell carcinima cell line A431 Bad gene was expressed.The cell proliferation was inhibited by 62.6% and colonogenesis by 39.9% by the transfection of the gene.Conclusion: Human Bad gene was successfully cloned.Transfection of basal cell carcinoma cells with the gene may inhibit the cell proliferation and colonogenesis.

OBJECTIVE: To study the change of consumption of antibacterial agents especially the ceftazidime and its effect on drug resistance of Pseudomonas aeruginosa (PA). METHODS: The consumption of the top ten antimicrobial agents in terms of cases/times of medication from 2005 to 2006 in a hospital and its correlation with the drug resistance of Pseudomonas aeruginosa were analyzed. RESULTS: A linear correlation was noted between the consumption of ceftazidime and resistance of Pseudomonas aeruginosa to ceftazidime and another seven antimicrobial agents in the next quarter (P

Henoch-Scholein purpura(HSP)is a common systemic vasculitis of the small vessel in children,with a variety of clinical manifestations.The main diagnostic criteria include palpable skin purpura.Patients who have gastrointestinal tract as the main symptoms suffer clinically abdominal pain and gastrointestinal bleeding,they are easily misdiagnosed before skin purpura,the rate of misdiagnosis can be as high as 87.5%,and the main treatment is early application-oriented glucocorticoids.This review include etiopathogenisis,pathogenesis,pathology,clinical manifestations,auxiliary examination and treatment about gastrointestinal manifestations in HSP.

Objective To evaluate lactulose breath hydrogen test in diagnosis of small intestinal bacterial overgrowth in children.Me-thods Thirty-five children,aged 3 to 13 years old with mean (7.72?3.06) years old presented with chronic diarrhea,abdominal pain and flatulence.Among them,18 cases were male and 17 cases were female.Breath hydrogen test was carried out after the administration of a 0.5 g?kg-1 or 10 g lactulose,which was 100 g?L-1 solution.After the ingestion of lactulose,the breath hydrogen was collected in every 20 minutes and up to 3 hours.Small intestinal bacterial overgrowth was diagnosed as positive when the hydrogen concentration increased more than 20 mg?m-3 in a sample.Results Eighteen cases in 35 (51.43%) children were positive and 17 cases were negative.Among these positive cases,8 cases in 18 (22.86%) patients were typically double peaks in breath hydrogen concentrations.Among the causes of small intestinal bacterial overgrowth in children,4 cases with chronic superficial gastritis,4 cases with chronic bacterial enteritis,2 cases with malnutrition and anorexia,1 case with volvulus of stomach,1 case with massive resection of small intestine,1 case with steatorrhea and 5 cases with unknown causes.Four cases of chronic bacterial enteritis were gained remission by antimicrobial agents.The other cases were treated by lac-to-and bifidbacteria probiotics.Seven patients of the clinical systems were controlled,3 cases were improved remarkably and 4 cases were failed.Conclusions The lactulose breath hydrogen test is validated as screening test in the diagnosis of small intestinal bacterial overgrowth in children.Antimicrobial agents and bifidbacteria probiotics is effective in treatment of small intestinal bacterial overgrowth.
