Objective To investigate the changes of antibiotic resistance and its correlations with antibiotics use density (AUD) in intensive care unit (ICU) after implementation of antimicrobial stewardship. Methods Data on AUDs and synchronous antibiotic resistance in ICU of the Affiliated Hospital of Taishan Medical University during 2010 and 2014 were retrospectively reviewed.Autoregressive integrated moving average ( ARIMA) model was used to identify the correlation between AUDs and antibiotic resistance.Results The total AUD which stood at 163.46 DDDs· 100 person-1 · d-1 in the year 2010 decreased to 68.20 DDDs · 100 person-1 · d-1 in 2014, and the most significant decreases were found in quinolones, imidazole, carbapenems, aminoglycosides, other beta lactam and macrolides. Synchronously, a wide range of improvements in antibiotic resistance of major pathogens were also observed from 2010 to 2014, and the improvements were positively correlated with the decrease of AUDs.However, antibiotic resistance in 2014 was not significantly improved compared with that in 2013. The rate of ciprofloxacin resistance in Pseudomonas aeruginosa and the resistant rates of amikacin, imipenem, and meropenem in Acinetobacter baumannii even increased in 2014.Conclusions With the implementation of antimicrobial stewardship, antibiotic consumption in ICU was decreasing, and antibiotic resistance rate in major pathogenic bacteria was decreasing.But the rebound in antibiotic resistance in some types of bacteria was also observed and should be put on enough caution.

BACKGROUND: Practice has proved that organic material and inorganic materials used alone are not ideal scaffold materials. Polylactic acid (PLA) possessing excellent biocompatibility, degradability and absorbability, PLAs composites will be one of the most important biocomposite in the 21~(st) century. OBJECTIVE: To observe the effects of PLA-chitosan fiber (CF)/hydrexyapatite-calcium silicate (HA-CS) on adhesion, proliferation and differentiation of osteoblasts. METHODS: The rat osteoblasts were obtained from the cranium of newborn Wistar rats within 24 hours, and primarily cultured using modified collagenase digestion. The cells were generated and their biological characteristic was examined by inverted phase-contrast microscope, hematoxylin-eosin staining, alkaline phosphatase (ALP) staining and mineralized nodules staining. Then the cells at passage 3 were co-cultured with PLA-CF, PLA-CF/CS and PLA-CF/HA-CS in vitro. At 3, 6 and 9 days of the culture, cell morphology was observed by inverted phase contrast microscopy. In addition, MTT assay and ALP activity test were used to observe the effects of three kinds of materials on cell differentiation and proliferation. RESULTS AND CONCLUSION: Osteoblasts attached on all three scaffold materials can adhere, grow, differentiate and proliferate. The effect of three materials on cell activity was PLA-CF/HA-CS>PLA-CF/CS>PLA-CF. The composite scaffold PLA-CF/HA-CS has a good compatibility, indicating that the material has a great potential for application in bone tissue engineering.

Objective To investigate the risk factors,clinical characteristics and outcomes in patients with acute myocardial infarction and history of stroke. Methods A total of 771 patients with acute myocardial infarction diagnosed and admitted to Xuanwu Hospital,Capital Medical University from January 2005 to March 2012 were analyzed retrospectively. They were divided into either a stroke group (n=387)or a control group (n=384)according to whether they had previous ischemic stroke or not. The risk factors for cardiovascular disease,clinical characteristics of the disease,and clinical outcomes of the patients in both groups were compared through the case control analysis. The endpoint events observed were acute ischemic stroke,cerebral hemorrhage,and cause of death during hospitalization. Results (1)The median age of the patients in both stroke and control groups was 71 (37-91 )and 62 (29-90 )years respectively. The female patients in the stroke group were more than those in the control group (n=125 vs. n=91). The incidence of complicated with hypertension (72. 9%[n=282]and 47. 6%[n=183]) and type 2 diabetes mellitus (39. 0%[n=151]and 20. 8%[n=80]respectively)were high. There was significant difference between the two groups (P<0. 01). (2)The time from the onset to admission in patients of the stroke group was longer than that in patients of the control group (median 11 h vs. 4 h). The incidence of non-ST segment elevation myocardial infarction (16. 0%[n = 62 ]and 1. 8%[n = 7 ] respectively)was higher. The incidences of complicated with gastric stress ulcer (7. 0%[n =27 ]and 2. 1%[n=8]respectively),atrial fibrillation (10. 6%[n=41]and 3. 9%[n=15]respectively),and acute pulmonary edema-cardiac function Killip class≥Ⅱ(51. 9%[n =201 ]and 37. 8%[n =145 ] respectively)were more higher. The findings of coronary angiography in patients of the stroke group were that the incidence of left main coronary artery or 3 -branch lesion higher than that of the control group (52. 9%[126/238]and 32. 4%[97/299]respectively). There was significant difference (P <0. 05). (3)The incidence of new stroke in patients of the stroke group (5. 7%[n =22 ]and 1. 8%[n =7 ] respectively)and in hospital mortality (13. 7%[n=53]and 7. 6%[n=29]respectively)were higher than those of the control group. There were significant differences (P<0. 01). Conclusion The age of the patients with acute myocardial infarction with previous identified history of stroke is older. The incidence of female patients is higher than that of the non-stroke patients,and most of them have risk factors that complicated with hypertension and diabetes mellitus. These patients often have the complications with peptic ulcer disease and heart failure,and their coronary angiography often show multi-branch lesions,and they are more prone to ischemic cardio-cerebrovascular events during the hospitalization.
