Objective To investigate the effect of extraction of radix isatidis on the expression of transforming growth factor(TGF-β)in lung tissues of rats with radioactive lung injury.Methods 72 female Wistar rats were randomly divided into 3 groups,blank control group(groupA,n=24),simple irradiation group(group B,n=24),irradiation with Chinese medicine group(group C,n=24).Rats in group A and group B were given distilled water 2 mL/200g by gavage for one week,the rats in group C were given extraction of radix isatidis 2 mL/200g(1.6 g/200 g)per day for one week,then the rats received irradiation,during irradiation,the rats' weight was measured once a week,to illuminate the end.After 10-time irradiation(the 30th day), and at 60 days and at 120 days after irradiation,the expression levels of TGF-βin lung tissue were detected;In addition each rat lung tissue morphology was observed.Results The expression levels of TGF-βprotein in group B reached peak at the 30 days after irradiation,which at different time points in group A and group C was significantly lower than that in group B(P<0.01).Rats of group A had no significant change in lung tissue.Rats of group B were observed inflammatory cells in interstitial pulmonary alveolar,alveolar structural damaging,interstitial pulmonary edema,interstitial hemorrhage and inflammatory pulmonary with alveolar cavity;Rats of group C pulmonary interstitial fewer inflammatory cells in alveolar damage were not obvious, with no-pulmonary interstitial edema, hemorrhage and no inflammatory symptoms, comparison between group B and C was not obvious. Conclusion Extraction of radix isatidis could reduce the expression levels of transforming growth factor(TGF-β)in lung tissues of rats with radioactive lung injury ,has better preventive effect on radioactive lung injury,could protect lungtissue from damaging,inhibite alveolar permeability,and present the effect of pulmonary edema.

Objective To observe the effect of functional training combined with Chinese medicine hot pack-electrotherapy on knee osteoarthritis. Methods60 patients with knee osteoarthritis were divided into two groups. The treatment group was treated with functional training combined with Chinese medicine hot pack-electrotherapy; the control group was treated with Chinese medicine herbs hot pack-electrotherapy only. They were assessed with Lysholm Knee Scale. ResultsAfter treatment, the scores of Lysholm Knee Scale improved significantly in both groups (P=0.000), and more in the treatment group than in the control group (P=0.013). ConclusionFunctional training combined with Chinese medicine hot pack-electrotherapy is an effective and safe treatment for knee osteoarthritis.

Stray light is a physical phenomenon that degrades visual quality when light scattering occurs in the human eye.It is a main cause of the disabling glare.Stray light originates in cornea,iris,sclera,lens and retina,and these ocular tissues contribute to the total amount of stray light in a normal eye.The light scattering intensity increases when the transparency of any optical element mentioned above reduces.Stray light can be measured by several different methods,but the measurements still lacks a standardized procedure and outcome.Further clinical study is necessary to quantify and standardize the measuring method of stray light.This article aims to introduce the concept,source and clinical significance of stray light,and to provide its advanced measurement techniques and methods.

Objective To study the correlation between organizational commitment of nurses and their intention to drop out. Methods Toally 304 contract nurses were recruited in this investigation. The questionnaires including demographic data, scale of organizational commitment and intention to drop out scale were used. Results The score of intention to drop out was 16.94 ± 2.16. The score on organizational commitment was 71.19 ± 6.65. There was a positive correlation between intention to drop out and organizational commitment among the contract nurses. Conclusions Improving contract nurses′organizational commitment can be an effective mean to reduce contract nurses′intention to drop out. It is an important means to promote the development of the nurse team and provide a reference for the scientific development of nursing.

OBJECTIVE:To investigate the study of traditional Chinese medicine (TCM) in the treatment of chloasma,and to provide reference for clinical treatment and study of chloasma. METHODS:Retrieved from CBM,Wanfang database,CNKI and VIP,usingchloasmaas subject,the literatures of TCM therapy were collected during Jan. 2003-Dec. 2012. Bibliometric meth-od was adopted to analyze included literatures statistically in respects of publication amount,periodicals,research institution,litera-ture types,citing references,other periodicals citatien times,fund support,distribution of provinces and cities. RESULTS:During 2005-2012,the amount of the literatures increased slowly. Among top 10 journals in the list of publication amount,only Chinese Journal of Aesthetic Medicine was not TCM journal and took up the first place. Among top 7 research institutions in the list of publi-cation amount,TCM colleges took up predominant place,followed by TCM hospitals. The types of the literatures were mainly case report,contrastive study before and after treatment,group-divided control study;the amount of group-divided control studies increased gradually year by year. The references cited were mainly English literatures. There were 82 literatures which were cited by other periodicals more than 10 times;the highest time of other periodical citation per literature was 47 times;only 11 literatures were supported by fund. The institutions of literatures authors were distributed in 32 provinces,cities and autonomous regions of China,mainly in the eastern coastal areas. CONCLUSIONS:More and more attention has being paid to TCM therapy for chloas-ma,but the scope and depth of the studies were inadequate. From the point of view of modern medicine,we can explore the patho-logical TCM mechanism and the treatment method of shortening the course of disease.

OBJECTIVETo assess the predict value of European system for cardiac operative risk evaluation (EuroSCORE) II on early death in patients with severe coronary artery disease undergoing active treatment.

METHODSConsecutive 2 240 patients with three-vessel disease ( with or without left main disease) diagnosed by elevtive coronary angiogram between July 2011 and September 2012 were screened for this study, data from 1 892 patients who underwent active treatments (percutaneous coronary intervention or coronary artery bypass grafting) were analyzed retrospectivly. The predicted 30 days operative mortality calculated with EuroSCORE II was compared with the actual one. The calibration and discrimination of EuroSCORE II were tested with Hosmer-Lemeshow χ2 test and area under receiver operating characteristic (ROC) curve respectively.

RESULTSAge was 61.0 (54.0-68.0) years old and 75.8% (1,435/1,892) were male in this cohort, 58.0% (1,097/1,892) patients received percutaneous coronary intervention and 42.0% (795/1,892) patients received coronary artery bypass grafting. The overall 30 days operative mortality was 0.53% (10/1,892), 30 days operative mortality predicted by EuroSCORE II was 0.85% (95% CI:0. 44%-1.26%). The calibration (χ2 = 3.47 and P > 0.10) and discrimination (area under ROC curve was 0.75) of EuroSCORE II were satisfactory.

CONCLUSIONEuroSCORE II could precisely predict 30 days operative mortality for three-vessel disease patients with or without left main disease undergoing active treatments.
