Objective To investigate the resistance to fluoroquinolones and amikacin in escherichia coti isolates. Methods ESBLs-producers were detected by CLSI phenotypic confirmatory test and susceptibilities were tested by agar dilution method. Results 33. 8% of 361 isolates were ESBLs-producers. The resistant rate of ciprofloxacin,levofloxacin, amikaxin was 93.4%, 90.9%, 13.1% in ESBLs-produeers, and that was 69.5%,68.6 %, 19.7 % in non-ESBLs-producers, respectively. Conclusion Amikaxin is active against most escherichia coli isolates; those isolates are highly resistant to fluoroquinolones, especially, in ESBLs-producers.

Objective To learn the relationship between working pressure and mental health for nurse of transfusion room in pediatric department.Methods 120 nurses of transfusion room whose working years above half a year were investigated by questionnaire from January 2010 to December 2011.Results The maximal score of working pressure was working environment and resource (3.27±0.47),while the minimum was interpersonal relationship (1.80±0.68).The score of SCL-90 of the research group was higher than domestic model.More working pressures of transfusion room in pediatric department were positive correlated with SCL-90.Conclnsions In order to keep nurse sound in body and mind,the working pressure should be desolved in many ways.

Objective:To discuss the application of water-aided colonoscopy in the enteroscopy, and compare with traditional air insufflations colonoscopy so as to analyze the efficacy and safety of clinical enteroscopy.Methods: 248 patients accepted with non-anesthesia colonoscopy were enrolled in this study and they were divided into two groups (water-aided group,n=124, air insufflations group,n=124) as the random number table. All clinical data of two groups were collected, and the bowel preparation statuses of patients was evaluated when the colonoscopes were taken out. During detection, the success rate of intubation, the entrance time of colonoscope, the withdrawal time of colonoscope and the total time of examinations were recorded. After detection, the pains score of patients were recorded and evaluated, and a series of auxiliary operation in the process, such as the change of body position, abdominal compression and the adjustment for hardness were recorded. Results: The differences of bowel preparation status scores of left colon, transverse colon, right colon and the whole colon between two groups were not statistically significant(t=0.98,t=0.85,t=1.07,t=1.51;P>0.05). The difference of success rate of intubation between two groups was no significant(x2=0.73,P>0.05). The entrance time, the withdrawal time of colonoscope and the total time of intubation of water-aided group were significantly higher than these of air insufflations group, while the VAS of water-aided group was significantly lower than that of air insufflations group(t=5.78,t=3.85,t=5.64, t=10.25;P<0.05). Besides, there were no significant differences in the usage rates of abdominal compression, hardness adjustment and total usage rate of auxiliary operation between two groups(t=0.92,t=1.58, t=2.07;P>0.05).Conclusion: The water-aided colonoscopy can relieve pain of patients, and it doesn't affect the success rate of intubation for cecum.

Objective:To analyze the clinical efficacy of POEM treating patient with achalasia of cardia and observe the risk factor of effecting curative efficacy.Methods: 66 patients with achalasia of cardia who were treated by using POEM were enrolled in this study, and series of indicators of esophagus dynamics including LESRP, LESP, LESRR and LESL were detected in pre and post operation. Clinical symptom score system(Eckardt score) of achalasia of cardia was adopted to evaluate the effect of surgical treatment for patients at the pre and post operation 7d, and the diameter of widest part of esophagus at pre and post operation 7d were detected. The incidence rate of pneumoderm, substernal ache, pulmonary infection, pleural effusion, tunnel bleeding, postoperative reflux and esophageal perforation and other complications were analyzed and the relative risk factors of effecting curative effect were observed.Results: The LESRP and LESP of patients with achalasia of cardia of post-operative 7d were significantly lower than that of pre-operative 7d(t=12.74,t=17.56,P<0.05), while the LESRR and LESL of post operative 7d were significantly higher than that of pre-operative 7d(t=9.10,t=14.86,P<0.05) , respectively. And the Eckardt score and widest diameter of post-operative 7d were significantly lower than that of pre-operation(t=19.49, t=7.83,P<0.05), respectively. Besides, the incidence rate of complication of patients in post-operation was 48.48％. As the results of Logistic regression, age, Chicago type and Ling type were the risk factors that affect curative effect of POEM for achalasia of chardia. And as the analysis, the prognosis was better when the patient's age was less than 60 years, Chicago II type and Ling type.Conclusion: POEM can significantly improve the indicators of esophagus dynamics, and the complication will be few and the curative effect will be exact in middle and short term of post-operation by using this method. Therefore, it is a safe and effective surgical mode.

Objective To investigate whether serum level of low-density lipoprotein cholesterol can predict the expan?sion of hemorrhage growth in elderly male patients with acute hypertensive intracerebral hemorrhage. Methods Patients (n=108) who visited our hospital with from June 2012 until May 2014 spontaneous hypertensive intracerebral hemorrhage with?in 6 hours of onset which is confirmed by initial computed tomography (CT) were sent to repeated CT within 24 hours of on?set. All selected patients were divided into the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. Clinical data of these 2 groups were compared and the relationships of hematoma growth and its risk factors were analyzed. Results Baseline blood pressure, the level of blood glucose, PT, APTT, FIB, PLT and hemorrhage volume did not differ significantly between the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. The ratio of hemorrhage growth in LDL-C<2.49 mmol/L group was significantly higher than that in LDL-C≥2.49 mmol/L group (34.21%vs 11.43%). Multiple logistic regres?sion analysis showed that LDL-C<2.49 mmol/L was the only risk factor contribute to hemorrhage growth. Conclusion Pa?tients with LDL-C<2.49 mmol/L in acute intracerebral hemorrhage are of high risk of hemorrhage growth so early attention and appropriate procedure are needed to prevent or slow its growth.

Objective To investigate the effects of pentoxifylline on the cell proliferation of, collagen synthesis and TGF-β1 expression by human fibroblasts derived from keloid. Methods Skin samples were obtained from the lesions of 3 patients with keloid and normal skin of 3 human controls followed by primary culture of fibroblasts. Fibroblasts of 5th to 8th generation were cultured with pentoxifylline of 0.1 to 3 g/L for various durations. Then, MTT assay was performed to detect the cell proliferation of fibroblasts, double antibody sandwich-enzyme linked immunosorbent assay (ELISA) to measure the expression of TGF-β1, and reversetranscription PCR to examine the mRNA expressions of procollagen Ⅰ and Ⅲ in these fibroblasts. Results The pentoxifylline of 0.1 to 2 g/L markedly inhibited the proliferation of fibroblasts derived from keloid lesions and normal skin, in a dose- and time-dependent manner, with the strongest effect observed in fibroblasts treated with pentoxifylline of 2 g/L. A significant reduction was induced in the TGF-β1 mRNA expression in keloidand normal skin-derived fibroblasts by pentoxifylline of 0.5 to 2 g/L (all P < 0.01), and in the mRNA expression of procollagen Ⅰ and Ⅲ by pentoxifylline of 1 and 2 g/L (P < 0.05 or 0.01). Concretely, the relative mRNA expression level of procollagen Ⅰ and Ⅲwas 0.873 ± 0.077, 0.571 ± 0.050 respectively in keloid fibroblasts respectively, and 0.473 ± 0.035, 0.370 ± 0.045 in the control fibroblasts, after treated with pentoxifylline of 1 g/L, 0.750 ± 0.036 and 0.433 ± 0.045 respectively in keloid-derived fibroblasts, 0.390 ± 0.030 and 0.250 ±0.123 respectively in the control fibroblasts, after treated with pentoxifylline of 2 g/L, significantly lower than that in the keloid-derived (1.216 ± 0.061 and 0.953 ± 0.060) and control (0.836 ± 0.080 and 0.776 ± 0.041) fibroblasts without treatment. Conclusion Pentoxifylline shows an evident suppressive effect on the cell proliferation of, as well as the expression of TGF-β1 and procollagen Ⅰ and Ⅲ in fibroblasts derived from keloid lesions and normal skin.

BACKGROUND:In recent years,pentoxifyIline has been found to have a wide range of anti-fibrosis capacity However,there are few studies explore the suppress effect of pentoxifyIline on fibroblasts in human keloid.and the maximum inhibitory concentration remains poorly understood.OBJECTIVE:To study the effect of pentoxifyIline on proliferation activity of human keloid fibroblasts and to select the maximum inhibitory concentrationMETHODS:Human keloid fibroblasts were used as original cells,passaged till the 5~(th) to the 8~(th) generations.and then divided into the experimental and control groups.PentoxifyIline with concentrations of 0.1,0.25,0.5,1.0,2.0 and 3.0 g/L were added to the experimental group.The effects of different concentrations of pentoxifylline on proliferation of keloid fibroblasts were detected by MTT chromometry.RESULT AND CONCLUSION:Compared with the control group,the inhibitory effect of pentoxifylline on the proliferation of keloid fibroblasts was more evident in the experimental group(P＜0.05)The inhibition rates of pentoxifylline on proliferation of keloid fibroblasts showed apparently time-and dose-effect relationships within the concentration of 0.1-2.0 g/L.which presented a greatest level at 96 hours after culture.The maximum inhibitory rate was 53 37%,and the concentration was 2.0 g/L in the experimental group.Consequently,pentoxifyIline plays a notable inhibitory role in the proliferation of human keloid fibroblasts with concentration of 2.0 g/L at 96 hours after culture.
