Objective To evaluate the cost-effectiveness of edaravone dexborneol versus edaravone alone combined with conventional therapy in patients with acute ischemic stroke(AIS).Methods From the perspective of the healthcare systems,a decision tree model was constructed using the data from the randomized double-blind comparative trial of edaravone dexborneol in the treatment of acute ischemic stroke(TASTE trial).Cost-utility analysis was used to evaluate the health benefits of edaravone dexborneol at 1 month and 5 years.The robustness of the results was tested by single factor sensitivity analysis and probability sensitivity analysis.Results For AIS patients,the 1-month incremental cost-utility ratio was 53 212.89 yuan/quality-adjusted life-year(QALY),and the 5-year incremental cost-utility ratio was 49 631.25 yuan/QALY,both of which were smaller than China's per capita GDP in 2022(85 698 yuan).Univariate sensitivity analysis showed that the change of NIHSS score in 2 groups of improved patients,the probability of improvement in 2 groups and the probability of deterioration in edaravone group were the most influential factors on the outcome of incremental cost effectiveness.The results of probabilistic sensitivity analysis showed that edaravone dexcborneol was more economical when WTP was 1 times China's per capita GDP in 2022.Conclusion Edaravon dexborneol is a more effective and economical treatment for acute ischemic stroke patients than edaravone alone.

Objective:To investigate the construction effects of the graduate biochemistry technology courses based on the outcome-based education (OBE) concept, analyze the technical needs of graduate students, and further integrate and optimize the teaching methods.Methods:A self-compiled questionnaire with good reliability and validity was used to conduct an overall sampling survey on the graduate students who took the elective courses in Batch 2021 in a medical college in Shanghai. Excel and GraphPad Prism software were used for data analysis.Results:According to this survey, the courses gain good effects in terms of teaching framework, course facilities, teaching forms, teaching contents and comprehensive evaluation of teaching. A total of 112 students (95.2%) thought that the course was very helpful to the expansion of experimental technology and experimental operation ability. However, there were still some teaching needs, such as expanding the types of experiments and increasing experimental operations.Conclusions:Under the guidance of OBE concept, the construction of the graduate biochemistry technology courses has gradually achieved good results. Later, the online-offline hybrid teaching form will be further improved and the curriculum teaching arrangement will be optimized further.

Objective To explore the advantages and disadvantages of helicopter emergency medical services of South China in the long-distance transport for critical patients.Methods A total of 30 patients who received helicopter emergency medical services by Guangdong Generral Hospital from August 2004 to December 2014 were selected as the observation group,and the other 30 patients with similar conditions who received ground emergency medical services were selected as the control group.To analyses the difference between the two groups in the disease,transport distance,transportation time,costs and compliction by χ2-test,t-test and nonparametric test according types of data.Results There were significantly difference between two groups in transport distances (km) [578.0 (313.0,707.5)vs.214.5 (101.5,313.5),P <0.05],set-up time (min) [95.7 (56.7,133.4)vs.10.7 (6.8,15.7),P <0.05],transportation time (min) [112.3 (64.3,152.4) vs.146.8 (67.8,217.5),P <0.05],costs (yuan/h) [14378.5 (9887.0,16348.5)vs.557.0 (356.5, 787.5),P <0.05]and the distance/total time value [2.8 (1.3,4.8)vs.1.4 (0.8,2.8),P <0.05]. There was no significantly difference in the incidence of complications between two groups (χ2 =0.058,P >0.05).Conclusions Helicopter emergency medical services could shorten the transportation time of critical patients on long distance transportation,and improve the efficiency of first-aid.However,there were many disadvantages that need to be improved in the helicopter emergency medical service of China.

OBJECTIVESTo research the effects of supracondylar fractures of humerus treated by three different surgical methods.
METHODSThere were 103 patients with supracondylar fractures of humerus including 58 male and 45 female. The age was from 3 to 12 years old with the average of 7.4 years. To divide the cases into three groups by the operative approach in the humerus, the inside approach were in 37 cases (group A), the outside in 35 cases (group B) and the rear in 31 cases (group C). Comparing the reduction of the stretching and bending function of elbow joint and incidence of elbow varus.
RESULTSAll patients were followed-up for 1.5 to 8 years after operation with the average of 32 months. The reduction of stretching and bending function of elbow joint occurrenced in 6 cases in group A, 6 cases in group B and 25 cases in group C, the incidenc of group C were obvious more than group A and B (P < 0.01). The elbow varus occurred in 8 cases in group A, 17 cases in group B and 7 cases in group C, the incidence of group B were obviously more than group A and C (P < 0.05).
CONCLUSIONThere are different effects between three kinds of operative approaches in the humerus. The incidence of outside group is higher on the varus of elbow. The incidence of rear group is higher on the ability of elbow joint stretching and bending. The effect of inside group is sure on the operative approach in the humerus.

OBJECTIVE:
To observe the effects of systemic corticosteroids on the expression of Eotaxin in nasal polyps.
METHOD:
The SP immunohistochemical methods were applied to detected the expression of Eotaxin in nasal polyps before and after corticosteroids therapy. The optical density of positive cells in mucosal epithelia, vascular endothelia, inflammatory cells was measured by using HPIAS-2000 image-conduct system.
RESULT:
The expression of Eotaxin was positive in the cytoplasm of the mucosal epithelia,the inflammatory cells and the vascular endothelia in nasal polyps. The expression of Eotaxin was significantly reduced in the mucosal epithelia, the inflammatory cells and the vascular endothelia of nasal polyps after treated with corticosteroids compared with pre-treated.
CONCLUSION
Inhibiting the expression of Eotaxin in mucosal epithelia, inflammatory cells and vascular endothelia of nasal polyps, reducing recruitment and activation of eosinophil and relieving eosinophil inflammatory reaction in nasal polyps may be one of mechanisms of systemic corticosteroids therapy on the nasal polyps.

OBJECTIVETo study the relationships of experimental varicocele to the apoptosis of epididymis epithelium and changes of the contents of alpha-1,4-glucosidase and sialic acid from the unilateral epididymis in adolescent rats, and to investigate the effects of varicocele on the unilateral epididymis epithelium.
METHODSExperimental left varicocele models of 16 adult male Sprague-Dawley rats were obtained by partial ligation of the left renal vein. The epididymides were collected for detecting the apoptosis of epididymis epithelium and the contents of alpha-1,4-glucosidase and sialic acid by using spectrophotometry.
RESULTSSeven days after the establishment of the left varicocele model, the index of the apoptosis of the left epididymis epithelium was significantly higher (P < 0.001) and the contents of alpha-1,4-glucosidase and sialic acid significantly lower (P < 0.05, P < 0.005) in the experimental group than in the control.
CONCLUSIONThe results suggest that unilateral varicocele may increase the apoptosis of epididymis epithelium and the contents of alpha-1,4-glucosidase and sialic acid and subsequently affect the synthesizing and secretory function of the epididymis.
