Chinese Journal of Digestion 2012;32(4):245-248
ObjectiveThrough the examination of Clostridium difficile (Cd) in the stool of inflammatory bowel disease (IBD) patients to investigate its infection status in IBD patients and the relationship with IBD.MethodsFrom December 2009 to January 2011,a total of 130 diagnosed IBD patients were collected in the Department of Gastroenterology,Ruijin Hospital,Shanghai Jiaotong University School of medicine,including 60 ulcerative colitis (UC) patients and 70 Crohn's disease (CD) patients.At same time.60 irritable bowel syndrome patients and 60 healthy volunteers were collected as control.Stool samples were tested by PCR and Cd toxin A/B test kit (CDTK).SPSS statistical software was used for statistical analysis.ResultsIn 130 enrolled IBD patients,16 cases (12.3%) were Cd infected,of which 10 were UC cases (16.7%) and 6 were CD cases (8.6%).No Cd infection was found positive in control group (x2 =15.779,P=0.000).The infection rate of Cd in the patients of active stage was higher than that in the patients of inactive stage (x2 =10.092,P=0.001).The infection rate of coion-type CD patients was 4/14,which was significantly higher than those of other types CD patients (x2 =13.125,P=0.001).The infection rate of Cd was 4.5% in mild UC patients,14.3% in moderate and 6/17 in severe (x2 =6.667,P=0.037) ; the infection rate were 0% in mild CD patients,4.2% in moderate and 5/16 in severe.The infection rate increased along with the increase of The disease severity (x2 =13.907,P=0.000).There was no significant difference in the infection rate of Cd between broad-spectrum antibiotics used and not used patients (x2 =1.414,P =0.378), or between patients with broad-spectrum antibioticsused aloneand combinedwith immunosuppressant (x2 =0.330,P=0.962).ConclusionsThere was certain infection rate of Cd in IBD patients,especially the patients in active stage. The infection rate increased along with the increase of the IBD severity.

Objective To study the photodynamic therapeutical efficacy of a novel photosensitizer DTP on sensitive gastric cancer cells (SGC7901) and vincristine-resistant gastric cancer cells (SGC7901/VCR).Methods The P-gp expression on the SGC7901 and SGC7901/VCR cell membrane was indirectly confirmed by fluorescence microscopy.The survival rates of SGC7901 and SGC7901/VCR cells were evaluated by cell counting kit (CCK-8) after photodynamic therapy with DTP.The intracellular DTP uptake levels of two types of cell were determined using a fluorescence spectrophotometer,and the intracellular DTP distributions were observed by laser scanning confocal microscopy.Results The novel photosensitizer DTP has considerable photodynamic cytotoxic effect on SGC7901 and SGC7901/VCR cells.However,this effect on the SGC7901NCR cells was relatively weak (P<0.05),and could not be enhanced by P-gp inhibitor verapamil or cyclosporine A(P>0.05).The DTP uptake level in SGC7901 cells was higher than that in SGC7901/VCR cells (P<0.05),and could not be enhanced by P-gp inhibitor verapamil and cyclosporin A (P>0.05).It was found that DTP distributed in the lysosomes of SGC7901 cells and in the lysosomes and mitochondria of SGC7901/VCR cells.Conclusions The novel photosensitizer DTP is not the substrate of multidrug transporter P-gp,and its weaker photodynamic cytotoxic effect on SGC7901/VCR cells is independent of the P-gp overexpression on its cell membrane,which may be related to the distribution of intracellular DTP in the two types of cell.

BACKGROUND:The mechanical environment of skin tissue and spreading state of epithelial cels are closely related with the wound healing and scar formation process. OBJECTIVE:To analyze the effect of extracelular mechanical stimulation on cel spreading, to test the cel proliferation in order to analyze the effect of spreading form on cel proliferation and other physiological activities. METHODS: Cyclic sine wave mechanical stretching was exerted on immortalized human keratinocyte by using FX-4000 flexible substrate loading system, on the condition of 0.2 Hz and at frequency of 10% amplitudes. The spreading form was compared at 0, 24 and 48 hours, the cel proliferation was analyzed with flow cytometry, and the distribution of vinculin was analyzed with immunofluorescence staining. RESULTS AND CONCLUSION: human keratinocyte would keep the spreading state and could induce more cel proliferation by 24 hours mechanical stretching stimulation. Conversely, after stimulated for 48 hours, the morphology of the human keratinocyte was significantly changed, and the number of human keratinocyte in the division stage was larger than that in the static control group; under tensile stress, the distribution of vinculin was transformed from the surrounding nucleus membrane area to the cel edge. The results indicate that proper mechanical stimulate can increase cel proliferation with keeping cel spreading and adhesion state; the stimulating time of continuous cyclic stretching is the major factor to determine cel spreading morphology and adhesion regions of immortalized human keratinocyte.

Objective To investigate the clinical application of rhythmic abdominal lifting and compression cardiopulmonary resuscitation (ALC-CPR) in cardiac arrest (CA) patients with conventional cardiopulmonary resuscitation (CPR) contraindication (chest rib fracture, chest trauma, etc.).Methods The clinical data of patients with CA in emergency department of Hefei Second People's Hospital from June 2015 to December 2016 were analyzed retrospectively, and the patients with weights 40-150 kg and CA≤20 minutes, and resuscitated with ALC-CPR were selected. The vital signs and blood gas analysis indexes of patients before resuscitation and 30 minutes after return of spontaneous circulation (ROSC, after successful resuscitation) were recorded.Results A total of 19 patients with CA were treated with CPR-LW1000 type ALC-CPR apparatus for resuscitation, and with 12 males, 7 females; the age ranged from 43 to 87 years, and the average age was (70.32±13.49) years; there were 4 cases of heart disease, and 15 cases of non-heart disease. Compared with before resuscitation, the heart rate [HR (bpm): 115.05±21.70 vs. 0], mean arterial pressure [MAP (mmHg, 1 mmHg = 0.133 kPa): 66.05±11.69 vs. 0], pulse oxygen saturation (SpO2: 0.928±0.057 vs. 0.417±0.118), pH value (7.05±0.23 vs. 6.80±0.28), arterial oxygen partial pressure [PaO2 (mmHg): 65.42±19.11 vs. 42.42±10.78], HCO3- (mmol/L: 19.22±2.77 vs. 17.18±3.76) were significantly improved after successful resuscitation (allP < 0.05), and arterial blood carbon dioxide partial pressure (PaCO2) was decreased after successful resuscitation (mmHg: 53.72±13.23 vs. 57.66±14.86,P > 0.05).Conclusion Rhythmic ALC-CPR has obvious clinical value for CA patients with conventional CPR contraindication.
