The effects of Spirulina on intestinal microflora of diarrhea model mice were observed.Diarrhea model mice were geted by gastric perfusion ampicillin,then these mice were given different doses spirulina by gavage.Selective culture media were used to culture bifidobacteria,bacterium lacticum,enteric bacilli,enterococci,bacteroid,clostridium perfringens in feces at different times.In order to find the difference of collecting samples from feces and intestine,the quantity of detection flora in different segment of intestine were compared too.The result showed that in middle dose group and high dose group spirulina can regulate and improve intestinal flora of diarrhea model mice,and effectively shorten time from disturbance to balance.Fecal sample and intestinal contents sample both manifest a same trend,that is the quantity of bifidobacteria,bacterium lacticum in treatment recovery group is significantly higher than saline group,and enteric bacilli,enterococci,bacteroid,clostridium perfringens is significantly lower than saline group,but each index flora in intestinal contents sample has a significant difference in quantity.

Objective To analyze gene expression profiles of biopsy specimens from breast cancer patients who were treated with neoadjuvant chemotherapy(NAC) after biopsies, and to identify the genes which are closely associated with the efficacy of neoadjuvant chemotherapy with T/FAC [docetaxel(Taxotere), 5-fluorouracil, doxorubicin and cyclophosphamide] or T/FEC (Taxotere, 5-fluorouracil, epirubicin and cyclophosphamide) regimen.Methods We retrieved and collected gene expression profiles from publicly available databases.Four datasets, a total of 844 samples, were finally retained because all the patients had received a uniform neoadjuvant chemotherapy regimen.Response to neoadjuvant chemotherapy was categorized as a pathological complete response (pCR) or residual invasive cancer (RD).The differentially expressed genes (adjusted P-value<0.05) and therapeutic efficacy were analyzed and explored.Results After differential analysis, genes whose expressions were higher or lower in pCR group than in RD group were identified in each of the four datasets, respectively.There were 34 and 42 genes which were simultaneously more highly expressed or more lowly expressed in pCR group than in RD group in the four datasets.The unsupervised clustering, based on the 76 intersection genes, showed that the pCR specimens tended to form one cluster and the RD tended to form the other.Conclusion The seventy-six differentially expressed genes are associated with the efficacy of neoadjuvant chemotherapy and are likely to be novel predictive biomarkers for the efficacy of neoadjuvant chemotherapy.

Objectives To search for the pathogenesis of vaseular endothelial injury and its clinical significance.Methods 36 patients with acute lower respiratory trect infection(ALRI)and 30 healthy controls were envolved. Circulating endothelial cells (CEC)and nitric oxide (NO) levels were tested.Results Circulating nitrite/nitra levels,the stable metabolic products of NO,were found to be significantly higher in the patients with ALRI (44.6?22.6umol/L) than that in the controls (24.5?14.1umoI /L, P

OBJECTIVETo investigate the relationship between Helicobacter species and hepatocellular carcinoma(HCC).
METHODSLiver samples resected during operation from 34 patients with HCC diagnosed by histopathology and 20 without primary liver carcinoma as controls were studied. The two groups of sample were cranked out pathologic slice for in situ hybridization of Helicobacter, Helicobacter pylori and Helicobacter hepaticus. Qualitative and quantitative studies were used to assess the correlation of liver tissue Helicobacter infection with HCC.
RESULTS64.71% (22/34). of the samples of HCC showed positive for Helicobacter specific 16S rRNA-mRNA gene by in situ hybridization, while none was positive in controls (P < 0.01).
CONCLUSIONHelicobacter pylori were found in the liver of patients with HCC.

INTRODUCTIONMinimally invasive surgical ablation is an emerging alternative method to catheter ablation and the full surgical maze procedure for nonpharmacologic treatment of atrial fibrillation (AF). We present a totally thoracoscopic "box lesion" radiofrequency ablation procedure in patients with paroxysmal or persistent AF.
MATERIALS AND METHODSFrom June 2011 to October 2012, 14 patients with lone paroxysmal (n = 7) or persistent AF (n = 7) were enrolled in this study. Procedures were performed through 3 5-12 mm holes on each side of the chest wall. A bipolar ablation device was used to create a box lesion in the posterior wall of the left atrium that encircled the 4 pulmonary veins (achieving bilateral pulmonary vein/posterior left atrial wall isolation). Perioperative complications were recorded for all patients. Freedom from AF was assessed by 24-hour Holter monitoring every 3 months or during symptoms of arrhythmia.
RESULTSThe ablation was successfully performed in all patients, with median operation time of 128 minutes (range, 45 to 180 minutes). No operative mortality or morbidity were noted during the study period. Freedom from AF was achieved in 12 patients (85.7%) during follow-up (median follow-up 9 months). One patient with persistent AF was shifted to paroxysmal AF. No atrial flutter or atrial tachycardia was noted during the follow-up.
CONCLUSIONThese early results show that totally thoracoscopic surgical ablation using a unique "box lesion" procedure for persistent or paroxysmal AF is a feasible and effective method with good short-term results. Further study is necessary to validate this result.
