Objective To analyze the distribution and antimicrobial resistance of pathogens from patients with hospital infection in intensive care unit(ICU),and to discuss the corresponding strategy of prevention and treatment. Methods Clinical data of 891 patients hospitalized in the ICU of our hospital between Jan 2002 and Dec 2005 were collected.All the specimens were analyzed for pathogen distribution and resistance to antibiotics. Results Of all the isolated 1 155 strains,Gram-negative(G-)bacteria were the most popular pathogen(57.84%),whereas Gram-positive(G+) bacteria and fungi accounted for 21.39% and 20.78%,respectively.Most G-bacteria were less sensitive to imipenem(0-10.16%),and Pseudomonas aeruginosa was least sesitive to amikacin(6.89%) and cefoperazone-sulbactam(33.97%).G+ bacteria were most sensitive to vancomycin.Most fungus were Candida albicans(42.92%) and yeast species(22.90%). Conclusion Epidemiological investigation of pathogens in ICU is of great importance to the rational use of anti-biotics and may help to reduce the emergence of resistant strains.

AIM: To investigate the levels of IL-18, IL-16, IL-8, eotaxin and the chymase activity in the sputum of asthmatics. METHODS: IL-18, IL-16, IL-8 and eotaxin levels were detected with sandwich ELISA procedures and chymase activity was determined spectrophotometrically (410 nm) by the rate of hydrolysis of N-succinyl-L-Ala-L-Ala-L-Pro-L-Phe-p-nitroanilide (SAAPP). RESULTS: The specific chymase activities in the severe and moderate asthmatics were higher than that in controls. Native protease inhibitors ?_1-antitrypsin (?_1-AT) and soybean trypsin inhibitor (SBTI) inhibited 71.9% and 72.1% enzymatic chymase activity, respectively. The levels of IL-18, IL-16, IL-8 and eotaxin were significantly elevated in the sputum of patients with acute asthma. There were correlations between the levels of IL-8 and IL-16 (r=0.55, P

BACKGROUND: Acellular amniotic membrane used widely in treating ocular surface disease as well as extensive burn wounds due to its low antigenicity and excellent histocompatibility. However, it is poorly understood whether it can be used in repairing urethral defects.OBJECTIVE: To evaluate role and the feasibility of human acellular amniotic membrane (HAAM) in the rabbit urethral reconstruction.DESIGN, TIME AND SETTING: The randomized control experiment of animals was performed at the Laboratory Center of Guangxi Medical University between April and June 2007.MATERIALS: Thirty-two New Zealand rabbits were supplied by animal center of Guangxi Medical University. The human HAAM was obtained from Department of Obstetrics, First Affiliated Hospital of Guangxi Medical University.METHODS: HAAM was prepared by detergent-enzymatic approach. Firstly, the fresh amniotic membrane was protected with cross linking of 1% formaldehyde- 0.2% glutaral, digested with 0.125% trypsogen- 0.05 mol/L EDTA, followed by washing with 0.5% Triton X-100. Totally 32 New Zealand male rabbits were assigned into 3 groups: experimental group (n=12), control group (n=12) and sham operation group (n=8). Rabbits were prepared for urethral defects models in the experimental and control groups, which were repaired with HAAM or anastomosised directly. There was no urethral operation in the sham operation group.MAIN OUTCOME MEASURES: The growth of epithelial cells and smooth muscle cells, as well as inflammatory cell infiltration was observed by histopathologic examination at days 10, 21 and 42 after operation. The urethral pressure changes and urinary bladder was examined by retrograde urethrography at day 42 after operation.RESULTS: ①The prepared HAAM was translucent, there was no residual cells or fragments. ②The pathological section examination showed that in the experimental group, some epithelial cells has grown without acute rejection at day 10 after operation, and several layers of urothelium covered HAAM at day 21 with reduced inflammatory cell infiltration. At day 42, a sprinkle of smooth muscle grew in HAAM with few inflammatory cells. Urodynamic studies indicated that there were no significant difference among 3 groups in the bladder volume, maximum urethral pressure and minimum urethral pressure (P > 0.05). The weight of bladder had obvious difference between the sham operation and control groups (P < 0.05).CONCLUSION: HAAM is an ideal biomaterial with well histocompatibility, biocompatibility and low antigenicity. HAAM is a good choice for urethral reconstruction.

A central portion of nifS, designated nifS', was amplified from Azotobacter vinelandii. The nifS' was cloned into pUC18 to make pUCS. Then pUCS was integrated into Azotobacter vindandii chromosome DNA by homologous recombination. This nifS disruption mutants were generated by single cross-over event and selected by Amp resistence on BBGN medium. The nifS disruption mutant (named SU1) was affirmed by southern blot and PCR amplification. SU1 grows rapidly on BBGN, but very slowly on Burk's N-free medium. This phenomenon showes that SU1 nearly lost its nitrogen fixation ability because of the disruption of nifS. The successful construction of SU1 is helpful for further research on the effect of nifS on the structure and function of nitrogenase component-Ⅰ and Ⅱ.

Objective To investigate the clinical significance of serum omentin-1 levels in obesity and essential hypertension patients and its related influencing factors. Methods One hundred and thirty patients with obesity admitted to the Cadre Health Care Department of Navy General Hospital from Jun. 2011 to Dec. 2013 were enrolled in this study. According to the blood pressure,130 obesity patients were divided into simple obesity group( n=64 )and obesity hypertension group( n=66 ). Sixty non obesity patients with normal blood pressure were enrolled as control group. Serum omentin-1 levels were assessed by enzyme linked immunosorbent assay ( ELISA). Association between omentin-1 and biochemical parameters( including systolic blood pressure( SBP), diastolic blood pressure(DBP),body mass index(BMI),waist hip ratio(WHR),fasting blood glucose(FBG), triglyceride(TG),total cholesterol(TC),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol( HDL-C),fasting insulin( FINS),insulin resistance index( HOMA-IR)and high sensitive C reactive protein(hs-CRP))were analyzed. Results Serum omentin-1 levels in control group was(26. 7 ± 5. 1)μg/L, significantly higher than that in simple obesity group and obesity hypertension group((22. 1 ± 3. 2)μg/L,(18. 3 ± 3. 4)μg/L;F=33. 7,P﹤0. 01),and serum omentin-1 levels in obesity hypertension group was significantly lower than that in simple obesity group( t =21. 5,P ﹤0. 05). Pearson correlation analysis showed that serum omentin-1 negatively correlated with BMI,WHR,SBP and HOMA-IR( r = - 0. 447,- 0. 340,- 0. 350,-0. 397;P﹤0. 01). There were no significant relations between omentin-1 and age,DBP,FBG,FBG,TG,TC, LDL-C,HDL-C,FINS and hs-CRP( P ﹥0. 05 ). Multiple stepwise regression analysis showed that HOMA-IR, BMI and SBP were independent influencing factors of serum Omentin-1. Conclusion The serum omentin-1 level decreases in the obesity hypertension patients. Omentin-1 is negatively correlated with BMI,SBP,and HOMA-IR, which may contribute to the underlying pathophysiology of obesity and essential hypertension.

Objective To establish virtual three-dimensional instrument and cerebral aneurysm models by using three-dimensional moulding software,and to explore the effect of the models in interventional preoperative simulation.Methods The virtual individual models including cerebral arteries and aneurysms were established by using the three-dimensional moulding software of 3D Studio MAX R3 based on standard virtual cerebral aneurysm models and individual DSA image.The virtual catheter,guide wire,stent and coil were also established.The study of interventional preoperative simulation was run in personal computer,and included 3 clinical cases.Results The simulation results of the working angle and the moulding angle of the head of catheter and guide wire in 3 cases were identical with that of operation results. The simulation results of the requirement of number and size of coil in 1 case of anterior communicating aneurysm and 1 case of posterior communicating aneurysm were identical with that of operation results.The simulation results of coil for aneurysmal shape in 1 case of giant internal carotid artery aneurysm were more than 2 three-dimensional coils with size of 3mm?3 cm from the operation results,and the position of the second coil in aneurysmal neck was adjusted according to the results of real-time simulation.The results of retrospective simulation of operation procedure indicated that the simulation methods for regular and small aneurysms could become a routine simulation means but more simulation experience was needed to build up for the giant aneurysms.Conclusions The virtual three-dimensional instrument and cerebral aneurysm models established by the general software provided a new study method for neuro-interventional preoperative simulation,and it played an important guidance role in developing neuro- interventional operation.

OBJECTIVEObserve and analyze the informations of western medicine and traditional Chinese medicine in patients with coronary heart disease (CHD), in order to provide reference for clinical treatment.

METHODSelect patients with CHD in diagnosis of the first place in 17 hospitals, drug informations of these patients were analyzed using frequency method and association rules.

RESULTIn 84 697 patients,there were 47 564 males and 32 882 females. The median age was 71 years old, 76 172 patients have medicine records, including 278 kinds of western medicine and 331 kinds of traditional Chinese medicine. Aspirin was the most common used western medicine (51 132 patients, 67.08%), followed by isosorbide dinitrate, clopidogrel etc. The most common used traditional Chinese medicine was danhong injection, followed by shuxuetong injection. After classified the drugs, at the forefront of western medicine were antiplatelet drugs, nitrates drugs, statins, beta blockers, calcium antagonists, ACEI; the most used in traditional Chinese medicine was injection of blood-activating and stasis-resolving, followed by oral preparations of blood-activating and stasis-resolving medicine, Fuzheng class oral medicine, purgation medicine etc. After association rules, combination therapy among western medicine was the most common, combination of western medicine with blood-activating and stasis-resolving was very commonly, especially antiplatelet drugs and nitrates drugs.

CONCLUSIONWestern medicine in the treatment of patients with CHD was in accordance with the guidelines recommend, but with the lower utilization rate. Traditional Chinese medicine has become an important method for the treatment of CHD, promoting blood circulation and removing blood stasis is an important part of traditional Chinese medicine treatment in patients with CHD.
