ABSTRACT
OBJECTIVE@#This paper used plantar pressure analysis equipment to discuss the plantar pressure distribution pattern and balance ability of patients with the knee joint injury under static standing.@*METHODS@#Zebris FDM-S plantar pressure analysis equipment was used to collect plantar pressure data from subjects with the knee joint injury and healthy control subjects. We compared the pressure values in each region of pelma, and then assessing the balance ability of the subjects based on the trajectory of the overall pressure center movement.@*RESULTS@#Compared with the healthy control group, patients with knee joint injury have a significantly lower pressure in the heel areas and a significantly higher pressure in the middle foot area. And the total pressure of the injured limb foot in the patient group is lower than that in the contralateral foot. In addition, there is a significant increase in the parameters of the balance ability index in the patient group.@*CONCLUSIONS@#The plantar pressure distribution pattern of patients with knee joint injury is different from that of normal people in static standing, and the balance ability is poor. Therefore, this method has a positive guiding significance in the evaluation and application of knee joint injury.

OBJECTIVE To investigate the distribution and drug resistance of pathogenic bacteria from lower respiratory tract infection in elderly patients.METHODS A total of 1739 strains of bacteria isolated from sputum and lower respiration secretion culture of the elderly patients were identified and their drug resistance was tested by K-B method.RESULTS From 1739 strains of pathogens isolated,Gram-negative bacilli accounted for 63.8%.The main Gram-negative bacilli were Escherichia coli and Pseudomonas aeruginosa,Acinetobacter baumannii,Enterobacter cloacae and Klebsiella pneumoniae.Gram-positive cocci accounted for 22.9% and Candida albicans accounted for 13.3%,respectively.The resistance rates of Gram-negative bailli to imipenem,cefoperazone/sulbactam and amikacine were relatively low.And all Gram-positive cocci were sensitive to vancomycin.CONCLUSIONS The antimicrobial resistance of pathogens in elderly patients with lower respiratory tract infection is serious.It is important to mornitor the antimicrobial resistance.
ABSTRACT
OBJECTIVE To study the distribution and drug resistance of pathogens in urinary tract infection from elderly patients.METHODS A total of 406 strains isolated from urine culture of the elderly patients were identified and their drug resistance was tested by K-B method.RESULTS Among 406 strains the Gram-negative bacilli accounted for 67.0%.The majority of Gram-negative bacilli were Escherichia coli(156 strains),Proteus,Klebsiella pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii.Grampositive cocci accounted for 29.1% and Candida albicans accounted for 4.0%,respectively.The resistance rate of the main Gram-negative bacilli to imipenem,cefoperazone/sulbactam and amikacin was relatively low.And all Gram-positive cocci were sensitive to vancomycin.CONCLUSIONS The antimicrobial resistance of pathogens in elderly patients with urinary tract infection is serious.So it is important to monitor the antimicrobial resistance.
