Objective To compare the difference and rationalities between Harmm and Zhou' s formulae for expected acid-base compensation in acid-base imbalance. Methods 745 cases of arterial blood gas analysis results of acid-base disorder were evaluated respectively by Hamm and Zhou' s formulae, and the concordance was judged. Results For metabolic acidosis ( 108 cases), the concordance rate was 70. 4% between Hamm and Zhou's( Kappa value =0. 41 ,P ＜0. 01 ) ;for metabolic alkalosis ( 132 cases) ,the concordance rate was 59. 1% ( Kappa value =0. 18 ,P ＜0. 05) ;for acute respiratory acidosis(81 cases) ,the concordance rate was 65.43% ( Kappa value = 0. 31, P ＜ 0. 01 ) ;for acute respiratory alkalosis ( 168 cases), the concordance rate was 54. 8% ( Kappa value = 0. 24%, P ＜ 0. 01 ); for chronic respiratory acidosis ( 119 cases ), the concordance rate was 67.2% ( Kappa value = 0. 41, P ＜ 0. 01 ) ;for chronic respiratory alkalosis( 137 cases), the concordance rate was 66. 6% ( Kappa value = 0. 43, P ＜ 0. 01 ). Conclusion The difference between Hamm and Zhou' s formulae for expected acid-base compensation in acid-base imbalance was obvious. The Zhou' s expected max compensation coefficient were slightly higher than the primary adopted compensation coefficient.

Objective To investigate the effect of persistent hypoglycemia on the cerebral oxidative stress and matrix metalloproteinase-2 (MMP-2) activity of newborn rats and to explore the potential mechanism of hypoglycemia-induced brain injury of newborn.MethodsSeven-day-old rats were injected insulin subcutaneously to induce persistent hypoglycemia.Cerebral cortex,hippocampus and thalamus were collected after 36 hours' observation and stored in -80 ℃.Glutathione (GSH)and glutathione disulfide (GSSG) were detected by commercial kit and GSSG/GSH was calculated.MMP-2 activity was detected by gelatin zymography. The data were analyzed by t test,one or two-wayanalysis of variance and Pearson correlation analysis.Six rats were set as the normal glucose group. ResultsThirty-six hours after induction of hypoglycemia, the cerebral GSSG and GSSG/GSH of hypoglycemic pups elevated about 1.5 times higher than those of control group [GSSG:(15.89 ± 5.46) vs (6.15 ± 3.42) mg/g protein,t =3.704,P =0.004; GSSG/GSH:(5.58± 1.79) ％ vs (2.79±1.76) ％,t =2.712,P=0.022].The GSSG and GSSG/GSH in thalamus of hypoglycemia were significantly higher than those of control [GSSG:(15.93 ± 5.75) mg/g protein vs (5.03±5.14)mg/g protein,P＜0.05; GSSG/GSH:(6.50±3.25) ％ vs (2.41±3.12) ％,P＜0.05],whereas there were no significant differences in the cortex ard hippocampus.The total MMP-2 activity of hypoglycemic animals (2.22±0.59) was significantly higher than that of control (1.21± 0.17)(t=4.064,P=0.002),and significant differences were found between the two groups in cortex (2.14 ± 0.5 vs 1.17± 0.27),hippocampus (2.31± 0.72 vs 1.22 ± 0.37) and thalamus (2.22±0.68 vs 1.24±0.18) with all P＜0.01].The activity of MMP-2 was positively related to GSSG (r=0.575,P=0.0002) and GSSG/GSH (r=0.484,P=0.0003).ConclusionsOxidative stress might play an important role in the persistent hypoglycemia induced brain injury of 7-day-old rat pups and thalamus might be most vulnerable to hypoglycemia.Hypoglycemia might also elevate MMP-2 activity which is positively related to GSSG level and GSSG/GSH of the brain.

OBJECTIVE To investigate nosocomial infection and antibiotic resistance of Pseudomonas aeruginosa among geriatrics patients and to instruct clinical monitoring and control infection.METHODS P.aeruginosa isolates from geriatrics patients were identified and the resistance to antibiotics was determined by K-B method.RESULTS The risk factors of nosocomial infection were underlying diseases,low immunological function,long time hospitalization,invasive treatment,and prolonged antibiotic therapy.The resistant rates to trimethoprim/sulfamethoxazole and cefotaxime in PA were 74.8% and 60.2%,respectively.The resistance rate to imipenem was 3.9%.CONCLUSIONS It is suggested to carry out proper measurement to control the spread of multiresistant strains in order to improve the treatment of PAE infection in geriatrics patients.
