BACKGROUND:Preliminary data showed that the application of human platelet lysate to human umbilical cord mesenchymal stem cell culture can better maintain the characteristics of stem cells than the application of serum-free medium. However, the serum-free medium can better improve the proliferation of mesenchymal stem cells in vitro than the human platelet lysate.OBJECTIVE:To screen out a better mesenchymal stem cell cultivation system that can greatly maintain the characteristics and proliferation rate of human umbilical cord mesenchymal stem cells.METHODS:Six human umbilical cord specimens were inoculated in six culture systems, and the primary culture of umbilical cord mesenchymal stem cell was performed. These six culture systems were respectively MesenCult serum-free medium with 2% human platelet lysate (group A), StemPro serum-free medium with 2% human platelet lysate (group B), MesenCult serum-free medium (group C), StemPro serum-free medium (group D), low glucose-DMEM with 10% fetal bovine serum (group E), low glucose-DMEM with 10% human platelet lysate (group F). The cells were subcultured at 14 days after inoculation to compare the effects of different culture systems on the morphology, surface markers, differentiation and proliferation of human umbilical cord mesenchymal stem cells.RESULTS AND CONCLUSION:(1) The morphology of passage 3 cells in group D was elongated and uneven in size. The morphology of passage 3 cells was flattened in groups E and F, but the cells in the other groups were spindle-shaped and uniform. There were no significant changes in morphology and size between passage 3 and 5 cells in A and B. In group C, the morphology of passage 5 cells was more flattened and uneven in size compared with passage 3 cells. In group D, the morphology of passage 5 cells was more elongated than that of passage 3 cell. In group E, the morphology of passage 5 cells was more flattened than that of passage 3 cells. There was no significant difference in morphology between passage 3 and 5 cells in group F. (2) The expression rate of cell surface markers had no significant difference at different passages in each group. (3) The adipoinduction and osteoinduction rates were relatively higher in groups A and B compared with groups E and F, and lowest in groups C and D. (4) The cell proliferation rate for each passages in group A was significantly higher than that in group C. The cell proliferation rate for each passage in group B was significantly higher than that in group D. The cell proliferation rate for each passage in groups E and F was significantly lower than that in groups A and B. To conclude, these results suggest that the combination of serum-free medium with human platelet lysate could better maintain the characteristics and the proliferation efficiency of mesenchymal stem cells.

Objective To compare the clinic characteristics, recurrences and prognosis in patients with stage Ⅰ bronchioloalveolar carcinoma (BAC) and adenocarcinoma of the lung. Methods The data of 56 patients with stage Ⅰ BAC and 169 patients with stage Ⅰ adenocarcinoma were analyzed retrospectively. Results The overall 1-, 3-, 5- year survival rates were 94.7%, 83.5% and 61.2%, respectively. Compared with adenocarcinoma of the lung, BAC showed a better survival rate(x2 =6.36, P =0.012). After surgery patients with BAC were prone to develop intrathoracic recurrence, and adenocarcinoma was equal between intrathoracic recurrence and extrathoracic metastasis. The rate of intrathoracic recurrence and extrathoracic metastasis between BAC and adenocarcinoma was significantly different (14/16 vs. 27/59, x2 =8.85, P=0.004). In both group, preoperative asymptomatic patients had better survival rate(x2 = 7.28, P = 0.007; x2 = 6.07, P = 0. 014). Univariate analysis indicated that sex, age(< 60 years and ≥60 years), location of tumor and smoking history did not significantly influence survival in patients with stage Ⅰ BAC or adenocarcinoma (P > 0.05). Conclusion The prognosis of stage Ⅰ BAC is superior to that of stage Ⅰ adenocarcinoma. BAC is prone to develop intrathoracic recurrence, and adenocarcinoma is equal between intrathoracic recurrence and extrathoracic metastasis. Early diagnosis of lung cancer could improve long-term survival.

Early upper gastrointestinal cancer screening skills teaching is the vacancy and difficulty of endoscopic teaching and training. In this study, a standardized training program was set up for endoscopic physicians who had mastered the basic gastroscopy techniques. The training period was 12 weeks, including theoretical training, early cancer awareness training, standardized gastroscopy operation technology, endoscopic diagnosis of early esophageal and gastric cancer, and theoretical and skill examination.
