Objective To explore the effectiveness and safety of early feeding after intestinal resection and anastomosis in infants. Methods For this prospective randomized controlled study, clinical data were retrospectively reviewed for 86 infants undergoing stoma closure surgery from September 2018 to April 2021. They were assigned into infants with stoma due to congenital anal atresia (CAA) and infants with stoma due to neonatal necrotizing enterocolitis (NEC). And they were randomized into early feeding group (feeding at 24-48 h post-operation, n=20) and delayed feeding group (feeding at Day 5 post-operation, n=22). Age, weight, operation duration, bleeding volume, postoperative hospitalization stay, time to initial flatus/defecation and complication rate were compared between early feeding and delayed feeding groups. Results Forty-four CAA infants underwent colostomy. There were 23 in early feeding group and 21 in delayed feeding group. Mean time to initial postoperative flatus was shorter in early feeding group than that in delayed feeding group[(2. 65±0. 65) vs. (3. 24±0. 63) day, t=3. 049, P<0. 05]. Time to initial postoperative defecation was shorter in early feeding group than that in delayed feeding group[(3. 17±0. 71) vs. (4. 00±1. 00) day, t=4. 024, P<0. 05]. Average postoperative hospitalization stay became shortened[(8. 30±1. 66) vs. (11. 86±3. 86) day, t=4. 024, P<0. 05]; Average hospitalization expense declined[15 870. 68(13 536. 84-19 023. 80) vs. 18 001. 86(16 466. 08, 23 405. 25) yuan RMB, Z=-3. 072, P<0. 05]. All 42 NEC infants underwent terminal ileostomy. There were 20 in early feeding group and 22 in delayed feeding group; Mean time to initial postoperative flatus was shorter in early feeding group than that in delayed feeding group[(2. 45±0. 76) vs. (3. 95±0. 72) day, t=6. 581, P<0. 05]. Time to initial postoperative defecation was shorter in early feeding group than that in delayed feeding group[(3. 40±0. 88) vs. (4. 77±0. 42) day, t=6. 311, P<0. 05]. Average postoperative hospitalization stay became shortened[(9. 55±1. 67) vs. (12. 77±2. 56) day, t=4. 871, P<0. 05]. Average hospitalization expense decreased[17 100. 53(14 193. 25-22 249. 19) vs. 25 024. 26(19 887. 00-28 680. 01) yuan RMB, Z=-3. 072, P<0. 05]. Postoperative complication (n=1) occurred and there was no anastomotic leakage in early feeding group; postoperative complications (n=4) and anastomotic leakage (n=1) in delayed feeding group. Overall incidence of postoperative complications was not statistically significant between two groups (χ²=0. 706, P>0. 05). Feeding intolerance occurred in early feeding group (n=6) and delayed feeding group (n=1). The difference was statistically significant (χ²=4. 887, P<0. 05). Conclusion After bowel resection and anastomosis, early feeding can shorten the length of hospitalization stay and lower hospitalization expense. However, it does not increase the incidence of postoperative complications. As a result, long-term postoperative fasting is not required. However, time to start feeding should be formulated according to the specific surgical status of each child so as to lower the incidence of postoperative feeding intolerance. [ABSTRACT FROM AUTHOR]

All the living organisms can synthesize various fatty acids, which exist in different carbon chain length, configurations and biological functions. These fatty acids are involved in many important physiological activities including anabolism, energy metabolism, and signal transduction. The living organisms are also capable of degrading and utilizing fatty acids via different oxidative pathways and β-oxidation is one of the most important oxidative pathways in both prokaryotic and eukaryotic cells. Research in the model organism Escherichia coli has provided the most complete view of fatty acids β-oxidation. In this review, the progress of fatty acids β-oxidation in E. coli and other bacterial species were summarized. By taking the phytopathogen Xanthomonas as an example, this review then introduced the oxidation pathway and regulation mechanism of the diffusible signaling factor (DSF)-family quorum sensing signal (mid-chain unsaturated fatty acids). Based on current results, the specific enzymes required for β-oxidation of very-long-chain fatty acids, 3-methyl-fatty acids,Δ2 /Δ3 -unsaturated fatty acids, and polyunsaturated fatty acids were proposed. Finally, the key scientific questions to be answered in this field were prospected. This review provides a solid foundation for further study of fatty acid β-oxidation pathway and the underlying mechanisms of bacterial pathogenicity. [ABSTRACT FROM AUTHOR]

In order to obtain the relationship between the roughness parameters and the uniformity of the surface wear and the surface roughness of the friction pair, the current-carrying experiments were carried out under different experimental conditions. And the effect of contact current, contact pressure, sliding speed and running time on the roughness parameters was analyzed. When the other experimental conditions keep constant, the longer the running time and the greater the sliding speed, the greater the roughness of the contact surface, and the wear is more uneven. The greater the contact pressure, the smaller the roughness, and the wear is more uneven. The greater the contact current and the greater the contact, the surface roughness value decreases first and then increases slightly, and the wear becomes more and more uniform. [ABSTRACT FROM AUTHOR]
