ABSTRACT
Objective:To explore the operability of the Chinese version of the All Aspects of Health Literacy Scale (C-AAHLS) and the Brief Health Literacy Screening (BHLS) for assessing the health literacy level of surgical patients.Methods:A total of 202 surgical patients were recruited in an acute care hospital. C-AAHLS and BHLS were used simultaneously to measure the health literacy of patients, and the consistency of their measurement results was compared.Results:The total health literacy scores of 202 surgical patients measured by C-AAHLS and BHLS were respectively (23.16±2.94) and (7.50±3.58), both were at a medium level, and they are consistent in differences in the health literacy levels of different ages, occupations, and educational levels, with statistical significance; the Bland-Altman graph shows that the maximum difference between the measurement results of the two tools is 1.68 <1.824 (average value), the average value of the difference is close to 0, and the results are highly consistent (P < 0.0001).Conclusions:The results of C-AAHLS and BHLS in measuring health literacy are consistent, and clinical medical staff can choose the suitable measurement tool according to the appropriate situation.
ABSTRACT
Numerical simulation of the thyroxin producing process of a human body is presented to analyze the dynamic and static variation laws of the process. The relationship between the static value of thyroxin and the reaction coefficients of various physiologic chemical reactions upon the producing thyroxin is clarified. The simulation results provided in this paper can be utilized as some reference data for clinical pathogeny analysis of some thyroxin diseases.

The physiological feedback regulation mechanism of the heart rate variation due to the blood pressure variation is studied. The continuous closed-loop mathematical model of the heart rate feedback regulation system is constructed. Numerical simulation is completed based on the above model. The simulation results demonstrate that the regulation system has the ability to constrain the fluctuation of the blood pressure to certain extent. The results are helpful for the pathological studies of some hypertensive diseases.

Aim To establish a set of apparatus and method for the continued measurement of the oxygen consumption in mice. Methods The apparatus consists of a bottle with broad-neck for mice, basic burette, beaker containing water and some tubes for connection. Twenty mice were divided randomly into two groups and administered intragestrically propranolol 20 mg?kg -1 or equal volume of normal saline, respectively. The survival time and oxygen consumption were measured in mice subjected to normobaric and hypoxia.Results The survival time was prolonged by 43.35% (P
ABSTRACT
The pharmacokinetics of alprazolam in 18 rats was studied by using reversed-phase HPLC. The pharmacokinetic characteristics were fit to one compartment opened model after intragastric administration of alprazolam at doses of 50,20 and 2 mg ? kg-1, respectively. The absorbing and eliminating parameters between the three groups were no significant difference. Mean of Ka was 3. 3454 h-1,Ke 0. 3873h-1,T1/2Ka 0. 29 h, T1/2Ke 2.61 h, and Tmax 1.04 h. There was a positiverelationship between the serum concentration and dosage (r = 0. 6096, P
ABSTRACT
The pharmacokinetics and absolute bioavailability of 1-hexyl-carbamoyl-5-fluorouracil ( HCFU ) (10 mg/kg ) after oral and intravenous administration were studied in 5 dogs with cross-over design. The concentration of HCFU in serum was determined by reversed-phase high performanee liquid chromatography. After intravenous administration, the curve of serum HCFU concentration vs time was fit to a two-compartment opened model and the phar-macokinetic parameters were. T1/2?=1 .67 min, T1/2? = 34.55 min, Vc= 0.2525L/kg,C1 = 0.3205 L/kg?h~-1 & AUCiv =1.9375 mmol/min?L~-1. When HCFU tablets were tiken orally, the curve of concentration vs time was fit to an one-compartment opened model and its pharmacokinetie parameters were: T1/2ke=12.13 min, T1/2ke=38.51 min, Tmax=23.46 min,Cmax=8.140?10~-3mmol/L & AUCpo=1.5856 mmol/min?L~-1 . The absolute bioavailability calculated from AUCpo and AUCiv was 0.8214.
ABSTRACT
The influence of cimetidine on the pharmacokinetics of ftorafur ( FT-207 ) in 9 rats after intragastric administration were investigated with cross-over design. The concentration of ftorafur in serum was determined by reversed-phase HPLC. Its curve of concentration vs time was fit to one compartment opened model. The serum concentrations and areas under the curve ( AUC ) vs time were increased when cimetidine orally administered daily for 5d or single dose. The peak of serum and AUC of ftorafur were increased by 21 .0%(P
