Objective To observe the effects of different collagenase digestions on isolating human umbilical cord mesenchymal stromal cells (MSC) from Wharton’s jelly, to exam their differentiation ability and to investigate their passage effect on the immune phenotype. Methods Human umbilical cord samples were digested by collagenaseⅠorⅡorⅣfor 4-18 hours then were passed through sieves . Cells were collected by centrifugation then inoculated in DMEM/F12 medium at concentration within range of 4.8×103-1×104/cm2 to compare the effect of different digestions on MSC. Von kossa staining and tetracycline fluorescence was used to label the osteogenic differentiation capacity of MSC. Also RT-PCR was employed to identify the differentiate capacity of MSC into myocardial-like cells. The immunophenotype of MSCs were detected by flow cytometry after subculture. Results Using collagenaseⅠdigestion, the number of MSCs isolated from human umbilical cord in Wharton’s jelly and their vitality were much higher while the period to show cell extension and primary culture time were shorter than those using collagenaseⅡorⅣdigestions. The analysis of surface marker revealed that the expression of positive markers include CD29, CD44, CD73, CD90 and CD105 did not change with passages while the negative markers such as CD31, CD34 and HLA-DR increased significantly with passages;Differential experiments induced in vitro show that human umbilical cord MSC in wharton’s jelly had the ability to differentiate into osteoblasts and myocardial-like cells. Con?clusion The human umbilical cord MSC in Wharton’s jelly was successfully isolated by collagenaseⅠdigestion. This meth?od was simple with a high success rate while cell loss and damage were minimum. This makes large-scale cultivation possi? ble. Negative markers increased with cell passages. This phenomenon revealed that MSC showed directional differentiation.

Objective To understand multidrug-resistant organism (MDRO) healthcare-associated infection(HAI) in patients with malignant tumor, so as to provide basis for making HAI prevention and control measures.Methods Targeted surveillance method was used to survey MDRO HAI in patients with malignant tumor in a hospital from January 1 to December 31, 2014, WHONET 5.3 software was used to analyze the data.Results A total of 54 056 patients with malignant tumor were surveyed, HAI occurred in 3 542 (6.55%) patients, 847(23.91%)of which were MDRO HAI.Most patients(54.55%) with MDRO HAI were >60 years old.A total of 2 606 bacterial strains were isolated from patients with HAI, 847 (32.50%) of which were MDROs, and most were extended-spectrum beta-lactamases (ESBLs)-producing Escherichia coli (n=459, 54.19%).The major site of MDRO HAI was lower respiratory tract (47.34%).The top 3 departments of detection of MDROs were departments of thoracic surgery(17.12%), colorectal and anal surgery(9.92%), and general surgery (8.26%).Conclusion Incidence of MDRO HAI is higher in patients with malignant tumor, surveillance of high risk population and monitoring of antimicrobial resistance of pathogens should be strengthened, so as to reduce the occurrence of HAI.

Objective To investigate the relationship of nitric oxide with nitric oxide synthase system in fetal rat kidney and the mechanism of renal injury after acute intrauterine ischemia(hypoxia)/reperfusion ischemia(hypoxia)/reperfusion. Methods Wistar rats of 21 gestational days were selected and divided into seven groups according to the different ischemia(hypoxia)/reperfusion time. The level of nitric oxide and the expression of nitric oxide synthase system were detected by biochemistry, immunohistochemistry and RT PCR. Results The NO level was decreased gradually with extension of ischemia, which was significantly different from sham group ( P

AIM: To study the roles of endotoxemia in the occurence and development of cirrhosis. METHODS: The cirrhosis of rats were made by oral intake of thioacetamide (TAA-treated rats). A separate group of rats were subjected to a injection of small dosage of lipopolisaccharride (LPS) in the period of thiocetamide treatment in order to observe the possible effect of LPS on the forming of cirrhosis. RESULTS:Both plasma endotoxin levels and hepatic collagen contents were increased in TAA-treated rats,and there was a linear correlation between them ;Plasma and hepatic tumor necrosis factor (TNF?)、endothelin-1(ET-1)、nitric oxide(NO)、and MDA levels were all increased,and plasma endotoxin was correlated with all of their plasma contents;Only TNF? levels and hepatic collagen contents of TAA+LPS group were increased significantly compared with TAA group. CONCLUSION: These results suggest that endotoxemia (ETM) could play an important role in the development of cirrhosis mainly through activating Kupffer cells, which secrete TNF?, ET-1, NO and free radicals could be involved in the process.

AIM: To explore the effect of endotoxemia on hepatocarcinoma course induced by TAA. METHODS: The rat cirrhosis was induced by intaking TAA (0.03%) for four months, hepatocarcinom for six months. Lipoplysaccharide (100 ?g/kg) was administered subcutaneously every two days from the fifth month to the end of sixth month in TAA-treated rats. The plasma endotoxin content, ?-glutamyl transpeptidase(?-GT) activity, DNA index and aneuploidy index were determined, the point mutation of N-ras, p53 gene was detected in hepatocarcinoma rats. RESULTS: Endotoxin increased protein overexpression of p53, bcl-2 and N-ras , p53 gene mutation point and free radical production, reduced antioxidase activity and aggravated DNA damage in hepatocarcinoma rats. CONCLUSION: Endotoxin could accelerate hepatocarcinogenesis promoted by TAA.
