Objective To assess clinical results between proximal-first sequential anastomosis technique (POPCAB) and conventional technique off-pump coronary artery bypass grafting(COPCAB) in 72 patients over 65 years old.Methods Between Jan 2008 and Oct 2012,72 patients with multiple vessel coronary artery disease underwent off-pump coronary artery bypass grofting.They were divided into two groups,POPCAB and COPCAB groups.Preoperative and postoperative variables of two groups were compared.Results There were no significant difference in sex,age,history of acute myocardium infarction,hypertension,diabetes and number of bypass grafts between two groups.The ICU stay time in POPCAB group was less than in COPCAB group(P <0.05).There were lower creatine kinase MB and cardiac trop I after operation in POPCAB group compared with COPCAB group(P < 0.05).Conclusion The results confirm that promixal-first sequential anastomosis technique remains a valuable option of surgical myocardial revascularization,and may optimize the outcome in the aged.

A method for determination of seleninm in foods by hydride generation -atomic absorption spectrometry was described. Food samples were digested by heating with a mixture of nitric, perchloric, and sulfuric acids. After addition of 4ml of 6mol/L HC1, the digests were heated in a boiling water bath to reduce selenate to selenite. The hydride of selenium was evolved by reduction with 1% KBH4 from a system of 2mol/L HC1-1% K3Fe(CN)6 and then atomized in a laboratory-constructed electrically heated silica absorption tube. Absolute detection limit of the method was 2ng and the linear range was from 0 to 10 ng/mlSe. Recoveries of inorganic selenium added to a variety of foods ranged from 83% to 112%. Accuracies checked with standard materials of pig liver and brassica oleraca were within the certified values. The loss and pollution of selenium during the sample pretreatment were also studied.

Objective To understand the distribution and antimicrobial resistance of pathogens isolated from patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)in Ordos area,so as to provide guidance for rational antimicrobial use.Methods Sputum culture and antimicrobial susceptibility testing results of 372 patients with AECOPD in Ordos area in 2013-2015 were analyzed,and the quality of life before acute exacerbation was assessed.Results A total of 296 strains of pathogens were isolated from 372 patients,252(85.14%)of which were gram-negative bacteria,the major were Pseudomonas aeruginosa(n=58,19.59%),Klebsiella pneumoniae(n=51,17.23%),Acinetobacter baumannii(n=50,16.89%),Stenotrophomonas maltophilia(n=22,7.43%),Escherichia coli(n=19,6.42%),and Enterobacter cloacae(n=16,5.41%);27(9.12%)were fungi,the major was Candida albicans(n=19,6.42%);17(5.74%)were gram-positive bacteria,the predominant species was Staphylococcus aureus.Patients with CAT(COPD assement test)score≥10 had higher proportion of isolating Pseudomonas aeruginosa and Acinetobacter baumannii than those with CAT score<10.Conclusion The main pathogens from patients with AECOPD are gram-negative strains,CAT score prior to exacerbation may be related to the emergence of pathogens at AECOPD.

Emphysematous cystitis is a rare inflammation of the bladder, which can be life-threatening in severe cases. A senior gentleman with emphysematous cystitis was recently admitted to our hospital. He got bilateral renal hydronephrosis and bilateral terminal pneumatosis of the ureter. The comorbidity was prostatic hyperplasia and diabetes. After indwelling catheter , glucose levels control and anti-infection treatment for 3 days, the repeated CT showed the gas inside the bladder the end of ureter decreased significantly. The blood routine, urine routine, renal function was better than before. The patient was instructed to continue anti-infection treatment. The above laboratory examination indicators returned to normal after a week's re-examination.

Objective To measure the displacement of the silver clips guided by kV-plain film at state of moderate deep inspiration hold(mDIBH) assisted by active breathing control(ABC) and to explore the margin of clinical target volume(CTV) to planning target volume(PTV) for breast cancer patients treated with three-dimensional conformal external-beam partial breast irradiation (EB-PBI) assisted by ABC. Methods The patients undertook CT simulation assisted by ABC to get the CT images on the respiratory condition of mDIBH. Four selected silver clips in breast cavity were delineated and the cavity based on all of the clips were delineated as gross tumor volume (GTV). Before each irradiation, two orthogonal kV-plain films were taken for the patients in the respiratory condition of mDIBH assisted by ABC device. 2D-2D auto-matie registration was performed based on pixel between the kV-plain films and the digital reconstructed radi-ographs(DRR). Then manual registration was undertook to get the shifts of the four clips separately at LAT, LNG,and VRT directions. Based on the shift data,the margins of CTV to PTV at LAT,LNG and VRT direc-tions were calculated. Results The margins from CTV to PTV were 5.00 mm,7.78 mm and 9.30 mm at LAT,LNG and VRT directions based on the clip at cephal border of the cavity. The corresponding margins were 4.40 mm,6.43 mm and 6.73 mm based on the clip at bottom of the cavity;5.04 mm,8.63 mm and 10.54 mm based on the clip at lateral border of the cavity;5.40 mm,8.59 ram and 10.81 mm based on the clip at pedal border of the cavity. Conclusions The silver clips in breast cavity can be clearly showed on the kV-plain film. The displacement of the clips can be exactly measured by registration of kV-plain film and planning DRR in condition of mDIBH assisted by ABC. The margins from CTV to PTV for EB-PBI can be calculated based on the displacement of the clips.

Objective To explore the influence of different delineators and different delineating time on target determination of the whole breast and to explore intrafraction and interaction target displacements of the breast on moderate deep inspiration breathing hold (mDIBH) assisted by active breathing control (ABC) after breast conservative surgery. Methods Twenty patients received primary CT-simulation assisted by ABC to get five sets of CT image on the three breathing condition which included one set from free breath ( FB), two sets from mDIBH and two sets from deep expiration breathing control (DEBH). After radiotherapy with ten to fifteen fractions, the repeat CT-simulation was carried out to get the same five sets of CT image as the primary CT-simulation. The whole breast target were delineated at different time by the same delineator and delineated respectively by five delineators on the first set of CT images got with mDIBH from the primary CT-simulation,and to compare the influence of delineator and delineating time on the whole breast target. The total silver clips in the cavity were marked respectively on the two sets of CT images got with mDIBH from the primary CT-simulation, and to compare the intrafraction displacement of geometric body structured by the total of silver clips. The two ribs near the isocentric plane of the breast target were delineated respectively on two sets of the mDIBH CT image from the primary CT-simulation and on one set of the mDIBH CT image from the repeat CT-simulation, and comparing the movement of the point of interest (POI) of the ribs delineated to get the value of intrafraction and interfraction thoracic expansion. Results There was not statistically significant between the four volumes of whole breast targets delineated by the same delineator at different time, but with statistics significant between the volumes of whole breast target delineated by the different delineators(F = 19.681, P = 0.000). There was not statistically significant between the intrafraction displacements of the POI of the geometric body at each direction, and with no statistically significant between intrafraction displacements of the POI of the ribs delineated on the same mDIBH condition. There was not statistically significant between the interfraction displacements of the POI of the ribs delineated. Conclusions The influence of different delineators on the whole breast target is statistically significant. The difference of displacement of the breast target with the same mDIBH eondition assisted by ABC at the different direction is not statistically significant.
