RESUMEN

OBJECTIVE To evaluate the cost-utility of as-needed inhaled budesonide/formoterol versus budesonide maintenance therapy combined with as-needed inhaled terbutaline (hereinafter referred to as budesonide maintenance therapy) in patients with mild asthma from the perspective of the Chinese health service system. METHODS A Markov model of mild asthma was established based on an international multicenter randomized controlled clinical study (SYGMA 2 study); the model cycle was one week, and the model had a whole horizon of 60 years. The cost only included direct medical cost, and utility value was derived from the data of EuroQol 5-Dimension 5-Level in the SYGMA 2 study and published literature. The total cost and total output of the above two inhalation therapies for patients with mild asthma were calculated, with discount rate of 5%. The stability of the model was evaluated by sensitivity analysis. RESULTS The total cost of as-needed inhaled budesonide/formoterol and budesonide maintenance therapy were 25 884 yuan and 45 822 yuan, respectively, and the effectiveness were 30.51 quality- adjusted life years (QALYs) and 30.50 QALYs, respectively. The former scheme was an absolute advantage. One-way sensitivity analyses showed that the price of drug (terbutaline and budesonide/formoterol) and average number of inhalations per day were the main influencing parameters, but they had little influence on the results of basic analysis. Probabilistic sensitivity analysis showed that the probability of as-needed budesonide/formoterol being cost-effective was 100%. CONCLUSIONS Compared with budesonide maintenance therapy, as-needed inhalation of budesonide/formoterol in mild asthma patients is more cost-effective.

RESUMEN

This paper adopted UG8.0 to bulid the stent and blood vessel models. The models were then imported into the finite element analysis software ANSYS. The simulation results of ANSYS software showed that after endothelial stent implantation, the velocity of the blood was slow and the fluctuation of velocity was small, which meant the flow was relatively stable. When blood flowed through the endothelial stent, the pressure gradually became smaller, and the range of the pressure was not wide. The endothelial shear stress basically unchanged. In general, it can be concluded that the endothelial stents have little impact on the flow of blood and can fully realize its function.

RESUMEN

Objective To investigate a reproducible model of severe crush injury (CI) in rats.Methods A total of 50 clean grade male SD rats were randomly (random number) divided into 5 groups.Both hindlimbs of anesthetized rats were compressed by blocks weighing 3.5 kg,for 6 hours and followed by 3 hours of reperfusion on a specially notched device (group SP,n =10),ordinary compression (group NM,n =10) and simple control (group SHAM,n =10).Arterial tension,serum lactate,and potassium (K+),serum myoglobin (MB),aspartate transferase (AST) and alanine transferase (ALT),BUN and Cr were measured at 10 minutes after cannulaton,and 3 hours after release from compression.Muscles and kidneys were evaluated morphologically.Group D and E were treated in the same way and were observed for 72 h to get the survival rate of the NM group and the specially notched compression group.The SPSS 17.0 statistical software was used for statistical analysis,repeated-measures ANOVA analysis for the differences between groups,Kaplan Meier-estimator for survival analysis.Results The Specially notched compression produced a greater increase in serum lactate (F =39.626,P < 0.05),AST (F =24.965,P < 0.05),ALT (F =19.096,P<0.05),BUN (F=7.938,P<0.05),CR (F=14.787,P<0.05) and MB (F=16.840,P <0.05) by the end of experiment than NM group and simple control group.The direct cellular damage and ischemia-reperfusion injury were found under microscope.In crush injury caused by specially notched compression there was acute tubular necrosis found at 24 hours after injury.Mortality rate in the NM group was 20%,whereas mortality rate reached 90% in rats with specially notched compression (P <0.05).Conclusions It successfully developed a severe crush injury model in experimental rats,suggesting it is worthwhile to popularization.

RESUMEN

Retrospective analysis was conducted for the results of first-aid competitions so as to understand the present status of how emergency doctors of Hubei Province grasp the skills and consciousnesses of cervical immobilization.From 6 out of 19 teams,38 participating doctors from grade 3A hospitals provided patient cervical immobilization while 2 teams offered no cervical protection.It is necessary to intensify the skills and consciousnesses of cervical immobilization in clinical practice.

RESUMEN

Objective To evaluate the efficacy of multiple injection of morphine combined with phloroglucinol in the treatment of renal colic. Methods One hundred and twenty patients with severe renal colic were equally divided into three groups by random digits table,with 40 cases each group. The group A was administrated with physiological saline 100 ml and phloroglucinol 80 mg intervenous drop infusion combined with morphine 9 mg intravenous injection fractionated into three times, and the group B was administrated with physiological saline 100 ml and phloroglucinol 80 mg intervenous drop infusion,and the group C was administrated with physiological saline 100 ml intervenous drop infusion and morphine 9 mg intravenous injection fractionated into three times. At 10,20 and 40 min after administration, the antalgic efficacy of three groups were analyzed as well as the side effect. Results At 20 min and 40 min both of the total efficacy rates in group A[82.5%(33/40),95.0%(38/40)] were higher than those in group B [62.5%(25/40),80.0%(32/40)] and group C [60.0%(24/40),77.5%(31/40)] (P< 0.05),and the colic-exclusion rate in group A was also higher than that in group B and group C (P < 0.05). The difference of the efficacy rates in group A in these two time-points had no statistical significance (P >0.05). No increased pain occurred in group A except 1 case of vomiting. Conclusion Multiple injection of morphine combined with phloroglucinol is quick, effective and safe in the early treatment of renal colic.
