Objective To discuss the effects of health management model on mental health of undergraduates. Methods A total of 2244 freshmen from a college were randomly assigned to the study group (n =824) and the control group (n = 1420) in 2009. Chinese College Students Mental Health Scale (CCSMHS) was used to investigate the changes of the participants in the study group after receiving the health management and analyze psychological differences between 2 groups. Results In CCSMHS,all P was found to be less than 0. 05, except for anxiety ( t = 1.90, P = 0. 058 ), reliance ( t = 1.27, P = 0. 206), and impulse (t = -0. 60, P = 0. 551 ). In 8 dimensionalities with significant differences, scores were decreased after health management when compared with baselines. Instead of body ( t = - 1.38, P = 0. 168 ), all the other scores showed statistically significant differences between the 2 groups. Conclusion Mental health of those who received health management was better than those who didn't. However, anxiety, reliant, and impulse did not improve as a result of shorter intervention time, and the challenge facing psychology intervenion.

Objective To apply the virtual reality training in clinical education of rehabilitation therapy. Methods 26 undergraduate students majored in rehabilitation therapy were randomly divided into 2 groups during clinical education of physiotherapy. The experimental group (n=14) received virtual reality training first, and then with routine teaching, while the control group (n=12) learnt with routine teaching only. Self-assessment and physiotherapy test were conducted after training. Results The experimental group reported more interested, initiative and positive in training than those of the control group. The experimental group achieved higher scores in practical tests than the control group (P<0.05), while no significant difference in the theoretical examination between the groups. Conclusion Application of virtual reality training may improve the teaching of physiotherapy.

This paper briefly introduced the characteristics, some kinds of equipment, and the advantages of virtual reality technology in rehabilitation, especially in upper limb function rehabilitation, and its mechanism of motor function recovery after stroke. Some assessment tools commonly used for motor function were summarized.

Objective To analyze the characteristics of breast medullary carcinoma in CEUS and to compare with pathologic features.Methods Morphologic characteristics of 13 breast medullary carcinomas in CEUS were analyzed.The diameter of mass before and after CEUS were compared.Parameters from time-intensity curves of masses were analyzed in contrast with peripheral breast parenchyma.All the results from CEUS analysis were compared with pathological manifestations.Results Breast medullary carcinoma was characterized as irregular shape (n=10),clear margins (n=11) and uniform enhancement (n=11) in CEUS.These characteristics were in accordance with their morphologic characters in pathology.The diameter of mass before and after CEUS had no significant defference (P=0.61),which was in accordance with expansive growth in pathology.In contrast with peripheral breast parenchyma,the arrival time and time to peak of breast medullary carcinoma were significantly shorter (P=0.034,0.021),and peak enhancement intensity was significantly stronger (P=0.005),which were in accordance with the increased vascular density and their uniform distribution,big arteries at the margin of masses in pathology.Conclusion Breast medullary carcinoma has distinguished characteristics in CEUS,which are in accordance with characters in pathology,and can be used as the basis in clinical diagnosis and differential diagnosis of breast medullary carcinoma.

The existing problems in the construction of standardization of TCM information were discussed and suggestions were proposed to solve problems: to build the basic framework of standard system of TCM information; to cultivate professionals for the researches on the international standards of TCM information; to further explore the theories and methods about standardization of TCM information.

Objective To analyze the clinical features,epidemiologic information and outcome in confirmed cases of human infection with a highly pathogenic influenza A(H5N1).Methods The clinical features and epidemiologic findings in 2 confirmed cases of avian influenza A(H5N1)in Anhui province,in November 2005.Clinical data on vital signs,physical findings,laboratory tests and roentgenology were obtained by means of retrospective review of the hospital records.Epidemiologic data were collected through interviews of the patients and their relatives.Results In both cases,the diagnosis of influenza A(H5N1)was confirmed by means of viral culture and real-time polymerase chain reaction with specific primers for H5 and N1 in samples obtained from tracheal aspiration.All patients were previously healthy young women and resided in village.They had a clear history of di- rect contact with sick/dead poultry and prepared dead chickens at home for eating(removed feathers, washed,cut)hut no report of confirmed HSN1 animals in the village.The time between exposure and onset of illness were 5 days,no one else in family sick.The time between the onset of illness and hos- pitalization were 5 days and 6 days,respectively.Two patients have initial symptoms of high fever (typically a temperature more than 38℃).The prominent clinical features were those of influenza syndrome,including fever,cough,and shortness of breath.Upper respiratory tract symptoms were absent.The platelet counts were decreased.In both patients,there were marked abnormalities on chest radiography,radiographic changes include bilateral and unilateral lobular consolidations with air bronchograms,and had dramatic worsening of findings.Two patients developed acute respiratory dis- tress syndrome(ARDS)complicated multiple organ dysfunction syndrome(MODS)and died of pro- gressive respiratory failure.Conclusions Exposure to dead poultry within a week before the onset of illness was associated with Influenza A(H5N1)infection in humans,but no definitive evidence of hu man-to-human transmission has been found yet.Influenza A(HSNI)infection,characterized by fe- ver,an influenza-like illness with lower respiratory tract symptoms,carries a high risk of death.

AIM: To investigate the effect of ecdysterone (EDS) on H9c2 cardiomyocytes after oxidative stress.METHODS:H9c2 cells were cultured in vitro and divided into control group, high dose (2 μmol/L) of EDS group, middle dose (1.5 μmol/L) of EDS group, low dose (1 μmol/L) of EDS group, and H2O2 group.H9c2 cardio-myocytes in H 2 O2 group and high , middle and low doses of EDS groups were exposed to H 2 O2 for 6 h to establish the model of oxidative stress.The viability of the H9c2 cells was detected by CCK-8 assay.The apoptosis of H9c2 cells was analyzed by flow cytometry.The levels of lactate dehydogenase (LDH) and creatine kinase-MB (CK-MB) in the culture medium, and the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in the H9c2 cells were measured by colorime-try.The generation of reactive oxygen species (ROS) and the mitochondrial membrane potential were evaluated by flow cy-tometry and confocal laser scanning microscopy .The protein levels of Bax , Bcl-2 and cleaved caspase-3 in the H9c2 cells were determined by Western blot .RESULTS:Ecdysterone at the selected concentrations had no effect on the viability of H9c2 cells.Compared with control group, the levels of LDH, CK-MB, ROS and MDA, and the apoptotic rates of the H9c2 cells were significantly increased after treated with H 2 O2 , but were decreased by EDS treatment in a dose-dependent man-ner.The levels of SOD and mitochondrial membrane potential of the H 9c2 cells in H2 O2 group were reduced significantly compared with control group , but high, middle and low doses of EDS treatments up-regulated the levels of SOD and mito-chondrial membrane potential in H 2 O2-treated H9c2 cells.The protein levels of Bax and cleaved caspase-3 in the H9c2 cells in H2 O2 group showed significant elevation in comparison with control group , and the protein expression of Bcl-2 de-clined in H2 O2 group compared with control group , but high, middle and low doses of ecdysterone treatments down-regula-ted the protein levels of Bax , cleaved caspase-3 and up-regulated the expression of Bcl-2 in H2 O2-treated H9c2 cells. CONCLUSION:Ecdysterone attenuates the effect of H 2O2-induced oxidative stress on H9c2 cardiomyocytes.The mecha-nism may be involved in scavenging oxidative stress products , increasing antioxidant enzyme activity and improving mito-chondrial function .
