A field transfusion device without support is designed.It is in shape of cuboid,and the idler wheels of mean axis disc are driven by motor to push transfusion liquid into human body.A disc with 6 idler wheels on the edge is set in the motor axis.When motor starts,idler wheels take turns to extrude liquid from transfusion pipe to human body with transfusion speed decided by motor rotate speed.Besides,an adjustable transfusion controller,sensor for liquid pressure and transfusion alarm system are equipped.When the set transfusion volume is finished,it gives alarm.

In this study, radioimmunoassay (RIA) was perfomed to measure the contents of opiate peptide in plasma in control group and essential hypertension (EH) group before and after treatment. The relationship between the changes in opiate peptide content and mean artery pressure (MAP) was analysed. The results showed that the contents of ?-endorphin (?-EP) and leuenkephalin (LEK.) in the EH group were lower significantly (P

Objective To analyze the therapy method and the therapeutic effect of Jones fracture by using hollow screw internal fixation.Methods All the Jones fractures were treated by open reduction hollow screw internal fixation and the plaster external fixation were not used after operation.Results The 32 cases with Jones fractures got excellent 25 cases,good 6cases and poor 1 case which used by Maryland foot score system to appraisal.All the cases were followed up for 6 months to 30 months and the average follow-up time is 18 months.Conclusion The treatment of hollow screw internal fixation was a satisfactory method to cure Jones fracture,which had get advantages of simple operation,small wound,short operation time,not external fixation,quick recovery and few complications.

ObjectiveTo search a proper method for calculating the energy requirement in the patients with diabetes.MethodsBased on the energy metabolic characteristic of the patients with diabetes and main effective factors of energy requirement,such as age (A),height (H),weight (W),activity factor (AF)and climate factor (CF),we have established a formula:E(kcal)=[(H-A)×6+500÷WI2]×AF×CF.ResultsThis formula is of accuracy and applicabi-lity,compared with traditional method for calculating energy requirement.ConclusionIt is available that this method is used in dietotherapy of patients with diabetes.

Objective: To investigate the interaction between ciprofloxacin (CIP) and ferric-ion binding protein (FBP) from pathogenic bacteria, so as to determine whether FBP is the target of CIP. Methods: Reactions between ciprofloxacin and FBP from N. gonorrhoeae, which was expressed in E. coli, were monitored by UV-visible and NMR spectroscopy. Results: Fe3+ was removed from holo-FBP by CIP in 10 mmol/L Tris-Cl buffer, pH 7.40, at 298 K, and half of the loaded Fe3+ was taken off when 50 molar equivalence of CIP was present. Conclusion: CIP can remove Fe3+ from holo-FBP, indicating that CIP can interfere with the Fe3+ capture of the bacteria and influence the growth and virulence of the bacteria.

Objective To construct the recombinant adenovirus of Angiotensin Ⅱ type 2 receptor (AT2R), and study the effect of AT2R on prevention of neointimal hyperplasia in rat carotid arteries after balloon angioplasty. Methods The recombinant adenovirus of AT2R with green fluorescent protein was constructed by using the method of homogenous recombination in bacteria. AT2R gene was transduced into rat carotid arteries with pAdCMV/AT2R after the reproduction of rat carotid balloon injury restenosis model. The expression and the transfection efficiency of AT2R gene were evaluated by RT-PCR, immunofluorescence staining, and confocal microscope. The intimal/medial area ratio was measured by digital analysis system. Results The titre of purified recombinant adenovirus was 1.5?10 12pfu/ml, and it was proved by PCR. pAdCMV/AT2R transfection efficiency in carotid artery was about 40% at day14, and localized to the neointima, as well as to the media and the adventitia. pAdCMV/AT2R delivered into injured rat carotid arteries significantly up-regulated AT2RmRNA and protein expression in neointima from day 7 to 21 after injury. Compared with pAd-GFP transfection group, pAdCMV/AT2R transfection reduced I/M ratio significantly on day 21(0.78?0.06 vs. 1.36?0.21 respectively, P

The application of Standardized patient(SP) in Chinese clinical teaching is still in its infancy.The experience of SP in respiratory medicine teaching is also very limited.This article discusses the experience in applying SP in respiratory medicine teaching and several issues of SP training that should he paid attention to,and hrings forward our expectation in SP training in China.
