OBJECTIVETo compare the influence on the postoperative wound healing between inflatable pressure applicator and traditional pressure dressing.

METHODSFrom May 2009 to February 2010, 50 patients with closed femoral shaft fractures were randomly divided into group A and group B, with 25 patients in each group. There were 13 males and 12 females in group A, ranging in age from 38 to 60 years, with an average of (55.1 +/- 9.5) years; of them, road accident was in 18 cases, fall from heigh was in 6 cases, accidental falling injury was in 1 case. There were 15 males and 10 females in group B, ranging in age from 40 to 65 years, with an average of (56.5 +/- 9.2) years; of them, road accident was in 13 cases, fall from heigh was in 6 cases, accidental falling injury was in 6 cases. There was no significant difference between two groups in clinical data. The postoperative wounds of group A were binded with dressing of inflatable pressure applicator; and of group B with traditional pressure dressing. Volume of drainage at 12 h after operation, saturation of blood oxygen at 12, 24 h after operation, satisfactory rate of patients were compared between two groups.

RESULTSPostoperative volume of drainage in group A was lower than that of group B, respectively was (77.5 +/- 4.6), (94.3 +/- 3.8) ml. Saturation of blood oxygen at 12, 24 h after operation in A group was respectively (98.3 +/- 1.1)%, (98.9 +/- 0.8)%, and in group B was respectively (96.5 +/- 0.4)%, ( 97.0 +/- 0.3)%; there was significant difference between two groups at the same time. Satisfactory rate of patients in A group was better than that of group B.

CONCLUSIONInflatable pressure applicator can obviously pressurize and stop bleeding for postoperative wounds, but no affect on peripheral blood supply and can improve discomfort of patients.

Objective:To study the changes in total phenolic and flavonoid content and antioxidant enzyme activity of Polygala tenuifolia callus in MS medium with different concentrations of H₂O₂,in order to explore the physiological mechanism of Polygala tenuifolia callus in adapting to H₂O₂ environmental stress at the cellular level. Method:Five gradients of 0,5,10,15,20 mmol·L^-1 were set for H₂O₂ concentration and added to MS medium, with P. tenuifolia callus as the experimental material. Total phenols,total flavonoids and antioxidant enzyme activities of callus were determined after 5,10,15,20,25 d of culture,respectively. Result:The contents of total phenols and flavonoids were the highest when the concentration of H₂O₂ was 5 mmol·L^-1 for 15 d. The SOD activity was the highest when the callus was cultured for 5 d and the exogenous H₂O₂ concentration was 5 mmol·L^-1. POD activity was the highest at 25 d and 5 mmol·L^-1 concentration of exogenous H₂O₂.CAT activity was the highest at 25 d and 15 mmol·L^-1 concentration of exogenous H₂O₂. Conclusion:P. tenuifolia callus has the ability to adapt to the environmental stress of H₂O₂ at a certain concentration. When it is subjected to the environmental stress of H₂O₂,P. tenuifolia callus can alleviate the damage by regulating its secondary metabolites and protecting enzyme system. It can significantly promote the content of total phenols and flavonoids in secondary metabolites at 5-10 mmol·L^-1. SOD activity was significantly increased at 5 d and the concentration of exogenous H₂O₂ of 5 mmol·L^-1. POD activity was significantly increased at 25 d and the concentration of exogenous H₂O₂ of 5 mmol·L^-1. CAT activity was significantly increased at 25 d and concentration of exogenous H₂O₂ of 15 mmol·L^-1.

Objective To construct a model of Seasonal Autoregressive Integrated Moving Average (SARIMA) for forecasting the epidemic of Japanese encephalitis (JE) in Xianyang, Shaanxi, China, and provide valuable reference information for JE control and prevention. Methods Theoretically epidemiologic study was employed in the research process. Monthly incidence data on JE for the period from Jan 2005 to Sep 2014 were obtained from a passive surveillance system at the Center for Diseases Prevention and Control in Xianyang, Shaanxi province. An optimal SARIMA model was developed for JE incidence from 2005 to 2013 with the Box and Jenkins approach. This SARIMA model could predict JE incidence for the year 2014 and 2015. Results SARIMA (1, 1, 1) (2, 1, 1)was considered to be the best model with the lowest Bayesian information criterion, Akaike information criterion, Mean Absolute Error values, the highest R, and a lower Mean Absolute Percent Error. SARIMA (1, 1, 1) (2, 1, 1)was stationary and accurate for predicting JE incidence in Xianyang. The predicted incidence, around 0.3/100 000 from June to August in 2014 with low errors, was higher compared with the actual incidence. Therefore, SARIMA (1, 1, 1) (2, 1, 1)appeared to be reliable and accurate and could be applied to incidence prediction. Conclusions The proposed prediction model could provide clues to early identification of the JE incidence that is increased abnormally (≥0.4/100 000). According to the predicted Results in 2014, the JE incidence in Xianyang will decline slightly and reach its peak from June to August.

The life view of "human life is the most important" in Traditional Chinese Medicine (TCM) originates from the people-oriented theory of Chinese traditional culture, the benevolence thought of Confucianism, the rebirth thought of Taoism and the compassion thought of Buddhism. Taking the life view of "human life is the most important" as the starting point, it has formed medical ethics thoughts such as the social responsibility of saving the world, the medical practice purpose of treating all patients equally, the meticulous working attitude, the diligent and tireless learning attitude, and the exploration spirit of widely exploring the medical roots, which still has important educational significance. Therefore, the life view of "human life is the most important" should be integrated into the medical ethics education of medical students, and the medical ethics literacy of medical students should be improved through the following ways: strengthen the vocational ideal education of saving the dying and healing the wounded, and enhance the sense of social responsibility of medical students; consolidate the theme of life first classroom education and improve the professional identity of medical students; enrich and innovate the practice forms of protecting life, pay attention to the practicality of medical ethics education.
