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 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.

Objective:To observe the application of pulse indicator continuous cardiac output (PICCO) system monitoring in the treatment of patients with severe thoracic trauma with the complication of acute respiratory distress syndrome (ARDS).Methods: 60 patients with severe thoracic trauma with complication of ARDS were randomly divided into the PICCO group (30cases) and the PAC group (30cases). The differences of PaO2/FiO2 score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, mortality, mechanical ventilation time, ICU stay time and total treatment cost between the two groups were observed.Results: The PaO2/FiO2 of PICCO group in 1d, 3d and 7d were significantly higher than that of PAC group, respectively (t=4.46,t=3.87, t=5.15,P<0.05). In the 7th day, the APACHE II of PICCO group was significantly lower than that of PAC group (t=1.94,P<0.05). Besides, the mechanical ventilation time, ICU stay time and total treatment cost of PICCO group were significantly lower than these of PAC group, respectively (t=3.36, t=2.58,t=5.53,P<0.05). While there was no difference for mortality between the two groups (x2=0,P>0.05). Conclusion: In the treatment for patients with severe thoracic trauma with ARDS, PICCO system monitoring could reduce the mechanical ventilation time, ICU stay time and total treatment costs of patients, and enhance the treatment effect of patients.

Objective To investigate the effects of Xinnaoxuemianning combined with statins on carotid atherosclerotic plaque in patients with cerebral infarction. Methods 180 cerebral infarction patients were divided into the observation group (90cases) and the control group (90cases) by random number table method. The control group was given atorvastatin calcium tablets and the observation group was given additionally Xinnaoxuemianning. The changes and prognosis of carotid atherosclerotic plaques were evaluated before and after treatment, and the incidence of adverse reactions was counted. Results There were no differences in the carotid atherosclerotic plaque, TCM syndrome score and neurological deficit severity between the two groups before treatment. After treatment, the above indexes were significantly improved, and the increasing degree of the observation group was better than that of the control group. The incidence rate of adverse reactions was lower in the observation group than that in the control group (5.56％ vs.13.33％) (P<0.05). Conclusion Xinnaoxuemianning can reduce the carotid atherosclerotic plaque area and correct the unstable plaques in patients with cerebral infarction.

Objective To investigate the clinical value of vaginal myomectomy. Methods From March 2005 to May 2008,78 women with abnormal uterine bleeding were diagnosed with submucous myoma by hysteroscopy combined with ultrasonography. All the myomas were located in the lower uterine segment,and the diameter of the tumor ranged from 30 mm to 63 mm. The patients were divided into two groups to underwent vaginal myomectomy (vaginal group,36 cases) or abdominal electrotomy (open group,42 cases). The operation time,intraoperative blood loss,postoperative hospital stay and recovery of the two groups were compared. Results The vaginal operation was accomplished in all of the 36 cases. Compared with the open group,the vaginal group had significantly shorter operation time [(64.7?10.4) min vs (71.1?11.3) min,t=-2.599,P=0.011],less intraoperative blood loss [(200.0?38.4) ml vs (253.6?47.6) ml,t=-5.412,P=0.000],quicker recovery of bowel movement [(18.5?4.3) h vs (30.9?4.7) h,t=-12.078,P=0.000],and shorter postoperative hospital stay [(4.9?1.2) d vs (7.0?1.3) d,t=-7.368,P=0.000]. Follow-up was available in all of the 78 cases for 3 to 40 months (mean,28 months),during which no relapse occurred,and no statistical differences in pregnancy rate between the two groups was revealed [2.8% (1/36) vs 4.8% (2/42),?2=0.000,P=1.000]. The operation satisfaction rates in both of the two groups were up to 100%. Conclusions Vaginal myomectomy has advantages in less hemorrhage,fast recovery,short postoperative hospital stay,and low complication rate. For the tumors located in the lower uterine segment or those larger than 30 mm in diameter,vaginal myomectomy is an alternative to hysteroscopic electrotomy.

OBJECTIVE To investigate the changes in and clinical significance of C-reactive protein(CRP) and endotoxin in patients who are firstly examined in fever clinic.METHODS To review and study the results of CRP and endotoxin from 81 patients(including 48 patients who were diagnosed as bacterial pneumonia and 33 patients who were diagnosed as a cold) in fever clinic of our hospital in 2005.RESULTS In 81 bacterial infection patients, the analysis indicated the levels of endotoxin between the pneumonia patients and the patients with a cold had significant difference.And the levels in the first group were significantly higher than in the latter one.The levels of CRP had no difference in two groups.CONCLUSIONS The result indicates plasma endotoxin detection helps to determine the early diagnosis of serious infection.It is also of significance to select antibacterial rationally and handle syndrome in time.In fever clinic,the levels of endotoxin may be a method to help diagnosis and treatment.CRP could be help to estimate the bacterial infection or virus infection,but it could not adjudge the seriousness in bacterial infection.

AIM: To establish the co-culture mode of tissue-engineered tracheal seeding cells, and compare with the routine culture, so as to provide the fundament of tissue-engineered trachea construction by cell compound materials. METHODS: The experiment was completed at the laboratory, Department of Respiratory Diseases, Tangdu Hospital, the Fourth Military Medical University of Chinese PLA from May 2006 to May 2007.①Three healthy New Zealand male rabbits, weighed (250.00?0.75) g, were used in this study.②Co-culture mode: The tracheal epithelial cells and fibroblasts were isolated and then co-cultured for 7-10 days. The two kinds of cells were distinguished according to their different tolerances to trypsin. Subsequently, A hole received 0.5 g/L trypsinization, cells were suspended in DMEM medium containing 0.05 volume fraction of CO2 and then transplanted into B hole (fibroblasts); again, A hole was added with 2.5 g/L trypsin for digestion, afterwards cells were suspended with K-FSM medium and transplanted into C hole (tracheal epithelial cells). Routine culture: after isolation, tracheal epithelial cells were cultured and fibroblasts were purified, respectively.③The co-cultured cells and the traditionally cultured cells were compared via cell growth curve and cell proliferation detected by 3-(4,5-dimethylthiazo-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay. RESULTS: ①Cell growth: Co-cultured cells grew well, those in A hole increased intercellular apace after trypsinization, while cells in B hole were shaped as fusiform, without the manifestation of typical road stone-like cells, and cells in C hole were apposite, showing lamellar road stone-like morphology.②Cell growth curve: The growth curve of co-cultured cells was identical with that of cells by routine culture method.③Cell proliferation: MTT detection revealed no significant difference in the proliferation of co-cultured cells and cells cultured by traditional method (P
