BACKGROUND:Umbilical cord stem cel s mainly derive from ful-term infants, and common culture methods include tissue-attached method and trypsin-digestion mehod. However, effects of different culture methods on the separation of umbilical cord mesenchymal stem cel s remain many disputes. OBJECTIVE:To observe the effects of different culture methods on umbilical cord mesenchymal stem cel s. METHODS:Umbilical cords of 30 healthy ful-term and caesarean delivery infants were selected, and cultured using tissue-attached method or trypsin-digestion method to isloate and culture human umbilical cord mesenchymal stem cel s. Meanwhile, cel growth was measured by flow cytometry. RESULTS AND CONCLUSION:The fusiform-shaped cel s began to separate from the umbilical cord tissue that was primary cultured using tissue-attached method, and 10 days later, the cel fusion reached 80%;after the umbilical cord was cultured using col agenase-trypsin digestion for 5 days, a smal amount of adherent cel s with different shapes appeared, and the fiber-like cel s reached 80%of confluence until 2-week culture. There was no significant difference in the growth of umbilical cord mesenchymal stem cel s cultured by different culture methods (P>0.05). Moreover, cel s cultured by two methods were al positive for CD13, CD29, CD44 and CD105. These results demonstrate that human umbilical cord mesenchymal stem cel s exhibit a high success rate in primary culture using tissue-attached method, which is superior to the trypsin-digestion method.

BACKGROUND:Skeletal muscle satel ite cells are totipotential stem cells with multi-directional differentiation potential, locate in skeletal muscle interstitium, have a certain tolerance to ischemia and hypoxia, and are important cells in stem cellengineering.
OBJECTIVE:To establish a thrifty, convenient culture procedure and create a simple, efficient method to transfect skeletal muscle satel ite cells, and investigate genetic expression after the transfection for cellular cardiomyoplasty.
METHODS:Skeletal muscle satel ite cells were isolated from rabbit thigh and cultured. Their growth curves were determined by CKK-8 method. Grouped by different proportions of the plasmid and liposome, skeletal muscle satel ite cells were transfered by the enhanced green fluorescent protein plasmid based on liposome. After transfection, the efficiency and character of target genetic expression was determined.
RESULTS AND CONCLUSION:Satel ite cells were isolated, cultured and transfected successful y. In suitable ratio of plasmid and liposomes, the transfection efficiency reached up to above 35%. The target protein was expressed within 12 hours after transfection, reached maximum in 48-72 hours and decreased gradual y after one week. The expression stil could be observed two weeks latter. The enhanced green fluorescent protein plasmid conducted by cationic liposome could be transfered into skeletal muscle satel ite cells efficiently. The transfection efficiency was correlated closely to the ratio of plasmid and lipofectamine. The change of target gene expression depended on time.

Objective To develop an artificial neural networks tool and use it to identify proteomic patterns in serum so as to distinguish gastric cancer from controls. Methods Serum samples from 84 gastric cancer patients and 75 controls were randomized into training set (106 samples) and test set (53 samples). At first, samples of the training set were detected using SELDI mass spectrometry and CMIO protein chips. Using a multi-layer ANN with a back propagation algorithm, a proteomic pattern that could distinguish cancer from control samples was identified in the training set. The discovered pattern was then used to determine the accuracy of the classification system in the test set. Results Totally 5 differentially expressed proteins between patients and controls were identified. The five proteins (P < 0.05, m/z at 7567,6742,5262,4869, 4256) were chosen to develop ANN based diagnostic model. The model was blindly tested in the test set for diagnosing gastric cancer. The sensitivity and specificity was 90.0% and 91.3% respectively. Conclusions Combination of SELDI with the artificial neural networks can get a high sensitivity and specificity approach to identify the gastric cancer from the controls. The method shows great potential for early diagnosis of gastric cancer and screening of new tumor biomarkers.

BACKGROUND: Previous studies have found that skeletal muscle satellite cell transplantation can induce angiogenesisin myocardial infarction area, reduce infarct size and improve cardiac function. But the overall effect is not satisfactory.OBJECTIVE: To observe the survival of basic fibroblast growth factor (bFGF) gene modified skeletal muscle satellitecells in acute myocardial infarction and to observe the expression of bFGF gene and the effect of cell transplantation onangiogenesis in myocardial infarction area.METHODS: Eighteen New Zealand white rabbits were divided into three groups by random: skeletal muscle satellite cellgroup (control group), bFGF gene enhanced skeletal muscle satellite cell group (experimental group) and blank controlgroup. The left anterior descending branch of the coronary artery of the rabbits was ligated so as to establish an animalmodel of acute myocardial infarction in the former two groups. After labeled by DAPI before transplantation, the skeletalmuscle satellite cells, bFGF gene modified skeletal muscle satellite cells and the equivalent amount of DMEM/F12 wereinjected into the local infarct myocardium correspondingly. Samples were taken 4 weeks after transplantation. Then, thesurvival of skeletal muscle satellite cells and the expression of bFGF gene were observed under light microscope andfluorescence microscope, and the neovascularization in the myocardial infarction area was examined byimmunohistochemical staining.RESULTS AND CONCLUSION: No DAPI-labeled cells were visible in the blank control group, but in the other twogroups, a large amount of DAPI-labeled skeletal muscle satellite cells were seen in the infarction area. Enhanced greenfluorescent protein was highly expressed in the experimental group. Microvessel density in the infarction area washighest in the experimental group followed by the control and blank control groups (P < 0.05). These findings indicatethat bFGF gene modified skeletal muscle satellite cells can survive and promote neovascularization in the acutemyocardial infarction area.

Objective:To analyze the use status of antibiotics and the resistance of clinic isolate bacteria against the commonly used antibiotics before and after the intervention. Methods:Using the information retrieval systems, the consumption of antibiotics in the inpatients during the 1st quarter of 2012(before the intervention) and the same period of 2013(after the intervention) was com-pared. According to the defined daily dose ( DDDs) , the antibiotics were ranked, and the resistance rate against the commonly used antibiotics was analyzed. Results:Compared with the top ten before the intervention, the top ten after the intervention was changed sig-nificantly, however, cephalosporins was still the main species. After the intervention, the overall decline in DDDs was significant, the separation rate and distribution of bacteria remained stable. ESBLs enzyme production rate of Enterobacteriaceae Escherichia coli was re-duced by 7. 61%, and that of Klebsiella pneumoniae was reduced by 1. 34%, and the resistance rate against the commonly used antibi-otics was in an overall downward trend. The resistance rate of Gram-positive staphylococci against the commonly used antibiotics was de-creased, while that of Gram-positive enterococci showed notable difference. Conclusion:The DDDs of antibiotics and bacterial resist-ance rate are in an overall downward trend in our hospital after the intervention;however, there is still exception. Therefore, the clini-cal antimicrobial susceptibility tests should be performed as soon as possible to help the choice of antibiotics.
