OBJECTIVE:To evaluate the perioperative utilization of antibacterial drugs in patients undergoing modified radical mastectomy. METHODS: In this retrospective study, the perioperative utilization of antibacterial drugs in patients who underwent modified radical mastectomy during 2006 and 2006 were analyzed statistically. RESULTS: 100% of the patients received antibacterial drugs preventively. The problems involved in the preventive use of antibacterials manifested as medication without indications, irrational application of broad-spectrum antibacterials, frequent change of drugs, blind drug combination, inappropriate time of initial administration and prolonged drug use etc. CONCLUSION: The perioperative use of antibacterial drugs in patients undergoing modified radical mastectomy in our hospital is far from rational. The Clinicians' medication behavior should be standardized and supervision on rational drug use should be strengthened.

OBJECTIVE: To discuss the clinical characteristics and the patterns of allergic reaction(ADR) caused by aminoglycosides.METHODS: 98 ADR cases induced by aminoglycosides were retrieved from domestic journals reported from Jan.1990 to June 2007 for a statistical analysis.RESULTS: The ADR of aminoglycosides was closely related to route of administration,unreasonable application,allergic history,etc.CONCLUSION: The ADR of aminoglycosides and rational use of aminoglycosides should be strengthened further in the clinical practice.

Objective To study the CT and MRI findings of ganglioneuroma and compare with pathology . Methods Clinical data of 12 patients with ganglioneuroma confirmed by surgical pathology were retrospectively ana -lyzed.All patients underwent CT and MRI , and the results were compared with pathological results .Results The average size of the lesion was (4.7 ±1.2)cm,CT scan was uneven or uniform density.In MRI plain scan,T1WI showed heterogeneous low signal ,T2 WI showed uneven contour signal ,the middle part of the strip of low signal .12 cases received enhanced MRI scan ,there were four cases of non-enhanced,mild enhancement in 3 cases,uniformity progres-sive strength enhanced with two cases ,uneven progressive enhancement in 3 cases,there was 1 patient with edge of the annular reinforcing ,in accordance with CT scan results .Conclusion When CT and MRI used as the detection means of ganglioneuroma ,its performance has a certain characteristic ,and that reflects in large part the tumor shape ,size and tis-sue composition .And pathological tumor is rich in a lot of mucus matrix has a certain relationship .

Objective To investigate the prevention effect of Ezetimibe with loaded dose on hematologic parameters and re-infarction in patients undergoing PCI.Methods 240 cases of patients with non ST segment elevation myocardial infarction performed PCI from October 2012 to October 2014 were selected and randomly divided into two groups,the control group received conventional dose Ezetimibe 10 mg every time,qd,the study group received loading dose ezetimibe 20 mg every time, qd, both two groups treatment 30 days.The inflammatory factors, myocardial injury and vascular endothelial function were compared before, 24 h and 30 d after the operation, and patients were followed up for two years,record adverse reactions. Results Compared with before treatment,levels of serum inflammatory factor,myocardial injury and vascular endothelial function index in different time points had differences by single factor analysis of variance(P<0.05),and compared with the control group, levels of serum hs-CRP,TNF-α,IFN-γand IL-6 in the study group were lower, levels of serum CK-MB,cTnI and BNP were lower,the contents of ET in serum were lower,and the contents of NO were higher(P<0.05).The improvement degree in the study group of myocardial microcirculation perfusion after treatment was higher(P<0.05).No case shedding phenomenon occurred during the two year follow-up, and there was no statistical significance in the incidence of cardiovascular events between two groups.Conclusion Loading dose of ezetimibe can protect myocardium,and it can inhibit the inflammatory reaction and vascular endothelial injury caused by operation,it also can improve myocardial microcirculation.

Congenital anorectal malformation(CAM) is one of the most common colorectal diseases in children. Anoplasty has been the only treatment. Because of the fact that anorectal malformation is constantly complicated with congenital defect in the nerve and musculature, postoperative difficulty in defecation is common. Poor long-term quality of life of these affected children is a burden to the children, family, and society. With the advance of modern medicine, emphasizing the functional recovery after anatomical reconstruction of anorectum and conduction of individualized biofeedback training program to improve the defecatory function and long-term quality of life are the new treatment concepts and important progress. Novel methods for the prevention and treatment of CAM are still under exploration.

Diffuse alveolar hemorrhage (DAH) is a life threatening clinical syndrome caused by a variety of causes.Early identification and etiological diagnosis of DAH in children are challenging.Despite some advances have been made in the identification and management of DAH,the mortality rate is still high.This article aims to raise the cognition of clinicians on DAH by providing a general review of some recent researches.

This paper first explains the contextual theory,then it analyses the contextual characteristics under network environment with multimedia.At last,according to systematic functional linguistics,it discusses the implications of how to take advantage of the contextual characteristics in College English teaching and learning.

AIM: To quantitatively detect the expression level of transforming growth factor-β1 (TGF-β1) and transforming growth factor-β2 (TGF-β2) genes in the retina of normal rat in order to determine the expression difference of TGF-β1 and TGF-β2 in retina.METHODS: The total RNA was isolated from which the first strand of cDNA was prepared. The mRNA levels of TGF-β1 and TGF-β2 were detected quantitatively by real time polymerase chain reaction (PCR).RESULTS: The mRNA levels of TGF-β1 and TGF-β2 were 0.0008±0.0003 and 0.0378±0.009, respectively. Expression of TGF-β2 was obviously higher than that of TGF-β1 in rat retina with statistical significance (t=12.37, P<0.001). The ratio of TGF-β2/TG-β1 was 55.00±26.61.CONCLUSION: QRT-PCR could specifically and accurately detect gene expression level in rat retina. In retina the TGF-β2 gene was expressed more abundantly than TGF-β1. It is suggested that TGF-β2 play an important role in retina diseases.

AIM: To quantitatively investigate transforming growth factor-β type Ⅰ receptor (TβRⅠ) and transforming growth factor-β type Ⅱ receptor (TβRⅡ) gene expressions in rat retina.METHODS: Sprague-Dawley rats were chosen in this research. Gene expression was detected quantitatively by reverse transcription polymerase chain reaction (RT-PCR) analysis. RESULTS: The expression level of TβRⅠ and TβRⅡ were 0.00034±0.00013 and 0.0001±0.00005, respectively. The expression level of TβRⅠ was obviously higher than that of TβRⅡ in the rat retina with statistical significance (P<0.01). The ratio of TβRⅠ/TβRⅡ was 3.9±1.7.CONCLUSION: Real time quantitative RT-PCR is an effective method to detect differential expression genes in retina. The change of TβRⅠ/TβRⅡ expression may play an important role in the pathogenesis of retinopathy, which could be further investigated in its significance in the development of proliferation retinopathy.
