Methods Bacterial identification and antimicrobial susceptibility testing were?performed?with?MicroScan?WalkAway?96?PLUS?bacterial?identification?system.?All?the?data?were?analyzed?by?WHONET5.6?software. Results A total of 1499 clinical isolates were collected during 2015, of which gram positive organisms and gram negative organisms accounted for 24.7% and 75.3%, respectively. Prevalence of MRSA among S. aureus was 37.0% and MRCNS among CNS 86.3%. All (100%) Staphylococcus and E. faecalis isolates were susceptible to vancomycin, daptomycin and linezolid. About 2.8% of the E. faecium isolates were resistant to vancomycin. All the Streptococcus pneumoniae isolates were penicillin-susceptible, mainly isolated from children. The prevalence of extended-spectrum beta-lactamases (ESBLs) positive strains was 52.9% in E. coli, 30.8% in Klebsiella spp. (K. pneumoniae and K. oxytoca) and 25.0% in P. mirabilis. The ESBLs-positive strains showed higher resistance rate than ESBLs-negative strains to most antibiotics. The percentage of the P. aeruginosa isolates resistant to meropenem and imipenem was all 29.4%. The percentage of the Acinetobacter spp. (A. baumannii accounted for 85.5%) strains resistant to imipenem and meropenem was 63.0% and 64.5%, respectively. Conclusions Antibiotic resistance is still serious in Chuzhou First Hospital in 2015, especially the emerging carbapenem-resistant Enterobacteriaceae, which is of great concern.

Objective To investigate the effectiveness of early minimal enteral feeding′s prevention and cure of feeding intolerance of very low birth weight infants (VLBWs).Methods A total of 45 VLBWs from the neonatal intensive care unit(NICU) of the second people′s hospital of Shantou,were included,from 2011 Jan to 2012 Dec. 23 infants in the intervention group which were hospitalized in 2012,received early minimal enteral feeding (MEF), while 22 infants in the control group which were hospitalized in 2011,received routine feeding .The incidence of feed-ing intolerance of the two groups was observed .Results The incidence rate of feeding intolerance was 21.74%(5 cases) in the intervention group and 72.73%(16 cases) in the control group.The incidence rate of feeding intol-erance of the intervention group was lower than that of the control group obviously and the difference was statistical significance(P<0.05).The time to achieve full enteral feeding of the intervention group [(28.22 ±1.97)days] was significantly shorter than that of the control group [(34.23 ±3.10)days](P<0.05).Conclusion An early MEF is beneficial to reduce the occurrence rate of feeding intolerance ,achieve full enteral feeding sooner ,decrease the length of hospital stay and improve the life quality of VLBWs .

Objective: To study the effects of procyanidins extract from the lotus seedpod (LSPC) on active oxygen radicals and lipid peroxidation. Methods: (1) The scavenging effects of LSPC on O ?- 2 and ?OH was investigated by using chemiluminescence method; (2) The effects of different concentrations of LSPC on RBC auto oxidation and LPO formation of rat liver mitochondria in vitro were observed; (3) The LPO level of liver homogenates incubated with Fe 2+ and H 2O 2 in vitro were determined; (4) the mice were treated with a single intragastric feeding of 5% CCl 4 soya bean oil solution (10ml/kg bw) after seven days supplementation of LSPC 100, 200, 400 mg/(kg bw?d). The activities of SOD, GST and the level of LPO in liver and plasma of CCl 4 toxic mice were determined. Results: In vitro, LSPC 169.0mg/L or 105.3mg/L was shown to markedly scavenge O ?- 2 produced in xanthine/xanthine oxidase and ?OH in Fenton systems respectively, and could significantly inhibit the formation of liver LPO. In vivo, LSPC (100,200mg/kg) evidently reduced the level of LPO and increase the activities of SOD and GST. Conclusion: It suggests that LSPC may be used as an antioxidant and might effectively protect liver from the injury due to lipid peroxidation.

Iron is an essential nutrient element for human, but has potential toxicity. Under physiological conditions, the processes of iron absorption, transportation, cellular uptake and utilization, storage, release, excretion as well as regulation of iron metabolism maintain the iron homeostasis. However under pathological conditions, the iron metabolism changes and is associated with the pathological states. In order to realize the relationship between the critical illness status and the iron metabolism, we start with an analysis of the basic processes of iron metabolism in human and the toxicity of iron, followed by summary on the alteration of iron metabolism in the settings of pathological conditions, such as inflammation, infection and anemia, which often occur in critical illness. Then, we discuss the relationship between the prognosis and the parameters of iron metabolism. Moreover, we review the current researches on treatments related to iron metabolism, which involve the iron supplementation, iron chelation and agents regulating iron metabolism.
