The calculation of the shock tube parameter by Excel is introduced, the work was done with one dimension inviscid simulation. In the calculation, the driver gases were H
2
, He, Ar and their mixtures, and the experimental gases were N
2
and Ar. Additionally, the double diaphragm effect of the main diaphragm was considered, respectively obtained the operation parameters matching relationship, the best length ratio of driving section and driven section, the maximum test time under tailored interface condition.The study showed that, the parameter of the shock tube could be calculated by the software of Excel, the results could be shown in the designed table obviously, and they could be further processed to be a curve figure. The primary calculation results indicated that, compared to the ideal gas model, the shockwave was weaker and the test time was shorter with the real gas model. And the shockwave was strengthened by the diaphragm breaking with deflating gas between diaphragms.

Objective:
To investigate the effect of alcohol on the induction of long-term potentiation(LTP)in lateral perforant pathway(LPP)-CA3 area of rats and its possible mechanism.
Methods
Taking the method of electro-physiology record in vivo, through micro-injection of alcohol,naloxone and bicuculline respectively to hippocampal CA3 area, using the slope coefficient chang of field excitory postsynaptic potentials(fEPSP) as index,to observe the LTP induction change caused by high frequency stimulation.
Results
(1) Single application of alcohol into CA3 area inhibited the induction of LTP in a dose-dependent manner.(2)Micro-injection of naloxone or bicuculline before administration of alcohol into CA3 area partially reduced the inhibitory effect of alcohol on the induction of LTP.
Conclusion
The inhibition of alcohol on the induction of LTP in hippocampal CA3 area may be mediated by GABA energic system and endogenous opium system.

Objective
Arterial blood gas analyser and electrolyte analyser were used to measure arterial blood and venous plasma potassium and sodium ion concentration, the experimental data were statistically compared the differences between them and derived the linear relationship, discussed the clinical significance.
Methods
Using American production of GEM PREMIER 3000 blood gas analyser and Roche production of ROCHE 9180 electrolyte analyser, detected in 85 cases with arterial blood and venous plasma the potassium and sodium concentration, compared arterial blood and venous plasma potassium, sodium and relevance.
Results
Arterial blood and venous plasma potassium concentration were significantly different(
P
<0.05), arterial blood, arterial plasma and venous plasma sodium concentration were not significant differences(
P
>0.05),arterial plasma and venous plasma potassium or sodium concentration were not significantly different(
P
>0.05); and arterial blood and venous plasma potassium concentration in a certain linear relationship existed.
Conclusion
arterial blood potassium concentration is not the same with venous plasma potassium concentration, but according to the experimental data, can roughly calculate the linear regression equation of venous plasma and arterial blood potassium ion concentrationvenous plasma potassium ion(
A
) =1.445×artery blood potassium ion(
V
)-1.273(mmol/L), so when the doctor know the potassium concentration in arterial blood,can roughly calculate the potassium concentration in venous plasma, the doctor can comprehensively judge the potassium situation in patient.

Objective
To analyse the drug resistance rate of
Pseudomonas aeruginosa
in the Affiliated Hospital of Jianghan University, to provide direction for clinical drug application.
Methods:
To analyse the drug resistance of 138 cases which clinically isolated
Pseudomonas aeruginosa
from Jan., 2009 to Dec., 2010, and obtained the rate of antibiotic-resistance by WHONET5.4 software.
Results:
The highest detection rate of
Pseudomonas aeruginosa
came from the specimen of respiratory tract, which was 86.9%; These
Pseudomonas aeruginosa
were more sensitive to amikacin(87.0%)、sulbactam and cefopcrazone(83.8%),cefepime(79.4%), and then to ceftazidime(76.3%),aztreonam(68.5%); the resistance rates of
Pseudomonas aeruginosa
to cefotaxime(86.4%),levofloxacin(32.8%)were higher than other antibiotics.
Conclusion:
For the special drug-fast mechanism of
Pseudomonas aeruginosa
and the wide use of the broad-spectrum antibiotic, the resistance rate of
Pseudomonas aeruginosa
to antibiotic is higher and higher, and there are samples of
Pseudomonas aeruginosa
which are multi-drug-resistance, the infection always can not be cured by single antibiotic. The most effective method for preventing the fast development of resistance of
Pseudomonas aeruginosa
to antibiotic is early drug combination, strengthening the monitoring to the resistance rate of
Pseudomonas aeruginosa
, and analysis of drug sensitive test.

Objective:
To investigate the status of knowledge, attitude and behaviour of tuberculosis control among suspected tuberculosis in Wuhan city, and to provide the reference to tuberculosis education.
Methods:
The outpatient who with continuous cough, sputum more than two weeks or hemoptysis, sputum with blood were selected in the Wuhan Institute for Tuberculosis Control and the Tongji Hospital from Jul., 2010 to Sep., 2010.
Results:
The total awareness rate of key messages on tuberculosis control among surveyed people was 63.9%, the awareness rate of transmission was higher(78.8%), while the awareness rate of national policies on examination and cure on tuberculosis for free was lower(44.8%). Univariate and multivariate analysis showed that, household registration(OR=3.511, 95%CI1.579～7.805), education level (OR=2.302, 95%CI1.027～5.16), marriage status (OR=4.135, 95%CI1.832～9.337) were the main impact factors on the key messages awareness. About the attitude and behaviour of tuberculosis control, 38.7% had stigma of tuberculosis, 34.0% were afraid of tuberculosis.
Conclusion
The awareness rate of tuberculosis control is low among suspected tuberculosis outpatient in Wuhan city, it is necessary to conduct health education according to household registration, education level, and marriage status.
