RESUMEN
Superior vena cava syndrome(SVCS)is a group of clinical syndromes caused by obstruction of the superior vena cava and its major branches from various causes.Pulmonary artery stenosis(PS)is a complication of lung cancer or mediastinal tumours.SVCS combined with PS due to pulmonary metastases from bladder cancer is extremely rare and has not been reported in the literature.Here we reported an old male patient with pulmonary metastases from bladder cancer presenting with swelling of the head,neck and both upper limbs.SVCS combined with PS was clarified by pulmonary artery computed tomography angiography(CTA)and digital subtraction angiography(DSA).Endovascular stenting was used to treat SVCS.Angiography also showed that PS had not caused pulmonary hypertension and did not need to be treated.The swelling of the patient's head,neck and upper limbs was gradually reduced after the procedure.
RESUMEN
The thermotolerant bacteria which was isolated from the Apple Juice Concentrate(AJC) was investigated by comparison with the standard strain of Aliyclobacillus acidoterrestris DSM3922 using Kirin-medium acidified with malic acid.The results shows the two polluted bacteria isolated from AJC can grow under the temperature of 21?C～55?C and pH of 2.4～6.2,which was corresponded with the characteristics of the thermo-acidiphilic Alicyclobacillus spp..Further more,the cell morphology,colony morphology,cultural characteristics and physiological characteristics tests indicated the two isolated strains of thermotolerant bacteria have obviously similar characteristics with the standard strain of Aliyclobacillus acidoterrestris DSM3922.
