This study was designed to examine the effects of autophagy on the lipopolysaccharide(LPS)-induced acute lung injury (ALI)and to analyze the possible mechanism.Kunming mice of clean grade were randomly divided into 6 groups:control group(saline;ip);model group(LPS 10 mg/kg;ip);RAP group(rapamycin 6 mg/kg;ip);RAP+LPS group (RAP 6 mg/kg and LPS 10 mg/kg;ip);3-MA group (3-methyladenine 300 μg/kg;ip);and 3-MA+LPS group (3-MA 300 μg/kg and LPS 10 mg/kg;ip).6 h after LPS injection;mortality was checked.Neutrophil aggregation;and the expressions of TNF-α;LC3 and P62 in lung tissue were checked by fluo-rescence microscopy and Western blot.The results revealed a higher mortality;neutrophil infiltration and TNF-αexpression and significantly increased levels of autophagy marker LC3-II and P62 in LPS group;in RAP+LPS group;pretreatment with RAP notably reversed LPS-induced neutrophil infiltration and TNF-αexpression;LC3-II were further slightly increased;while P62 was significantly decreased;in 3-MA+LPS group;pretreatment of 3-MA slightly decreased LC3-II expression;P62;neutrophil infiltration and TNF-αremained almost the same to those in LPS group.These data suggesed that;in sepsis;autophagy flux in the lung tissue is partially blocked;and RAP help to alleviate LPS-induced lung injury;which might through promoting autophagosome maturation;smoothing autophagy flux;and eventually to mitigate pulmonary inflammation.

With the development of hospital information construction,the focus has gradually changed from functions of the information system to data utilization.The utilization of medical data has great significance in health management,disease analysis,summary of treatment experience,and development of new technologies.By data mining technology,the paper extracts data related to the author's hospital,starts from intelligent diagnosis and simulates the establishment of the knowledge base for hospital clinical diagnosis.Upon verification,the relevance judged by the system is basically consistent with the clinical practice.Thus,it proposes the possibility to extend the application to hospital clinical pathways.

AIM: To study the effects of M. vaccae on eosinophil apoptosis and Bcl-2 protein expression in lung tissues of asthmatic guinea pigs. METHODS: 30 guinea pigs were divided into normal saline (NS) group, asthma group and M. vaccae treatment group at random, every group included 10 guinea pigs. Guinea pigs in M. vaccae treatment group were injected intramuscularly with 22 5 ?g M. vaccae 10 days before OVA immunization. TdT-mediated dUTP nick end labeling (TUNEL) technique was used to investigate the apoptosis of eosinophils and immunohistochemistry method was used to study the expression of Bcl-2 protein in lung tissues. RESULTS: The apoptosis index (AI) of eosinophils in lung tissues in M. vaccae treatment group was significant higher than that in asthma group (23 78?5 42)% vs (4 56?0 68)%, P

Objective To investigate the mechanism by which electro-acupuncture (EA) promotes revascularization in the brain after focal cerebral ischemia and reperfusion.Methods The Sprague-Dawley rat model of focal cerebral ischemia was made by filament occlusion. The rats were randomly divided into a control group, a model group, and an EA group. The model and EA groups were each divided into 5 subgroups receiving reperfusion 1, 3,7, 14 or 21 days after ischemia. EA was given at the bilateral Hegn point (LI 4) in the EA group. The expression of stromal cell-derived factor-1α(SDF-1α) mRNA was detected using a RT-PCR in the 3, 7 and 14 day subgroups.The immunohistochemical method was employed to detect the expression of SDF-1α protein. Results Compared with the control group, expression of SDF-1α protein increased significantly in the model and EA groups. Compared with the model group, the expression of SDF-1α mRNA increased significantly in the 3, 7 and 14 day subgroups.SDF-1α protein expression and microvessel count increased slightly but not significantly in the 1d subgroup, but the increases were significant in the 3, 7, 14 and 21 day subgroups.Conclusions EA may promote angiogenesis in an ischemic area of the cortex by increasing the expression of SDF-1αmRNA and its protein after focal cerebral ischemia and reperfusion.

Study of kidney deficiency syndrome may utilize the modern molecular biology technique, such as gene chip, representational difference analysis (RDA) and genes sequence analysis, to clone the different genes of kidney deficiency syndrome from single TCM syndrome type of the disease, to investigate the inner connection between the various phenotypes of kidney deficiency syndrome and their genes expression pattern and their function products, then to definite the related genes of kidney deficiency syndrome. The research method may also be used for the study of other TCM syndrome types.

Objective To investigate characteristics of emotional intelligence(EI)and the ways of occupational stress coping in nurses as well as the predictive validity of EI on coping strategies.Methods 464 nurses from general hospitals were collected and evaluated with psychometric instruments including:Wong's Emotional Intelligence Scale(WEIS)and Nurse Ways of Coping Questionnaire.Data were conducted by Logistic regress analysis according to key themes.Results (1)Nurses' demographic characteristics had effects to the ways of occupational stress coping and emotional intelligence.However,there was no statistical difference of El varied with education levels(P＞0.05).(2)Both problems solving and positive recognition are main coping styles of nurses towards occupational stress.Either avoidance or self-reproach was seldom coping strategies of nurses toward occupational pressures(2.60±0.55;2.60±0.75;1.37±0.69;respectively).(3)El was correlated with coping styles(r=-0.123～0.253,P＜0.05,P＜0.01).Conclusion Four dimensions of EI positively or negatively predicted six kinds of occupational stress coping strategies separately.

In order to nurture the undergraduate majors of nutrition to fit society’s need,it is necessary to establish a new market-oriented talent training mode adaptable to both the market and society. This mode can also provide reference for the talent training of other emerging professions. Exploring the argument basis,theoretical design,practical development and research plan of this mode.

In view of China's medical equipment industry has not been equipped with a sound system and strict administration, it is wise to draw on FDA recommendations and seek effective ways of solving EMI problems. Further should focus on improving the performance of medical equipment so as to adapt to the different environment. In the end, the design of healthcare facilities to meet EMC standards is put forward specifically in four parts of electronic circuits, power circuits, display device, and the mechanical shell.

Objective To manufacture the skin suction blister apparatus and observe the curative effect of autologous epidermal grafting in treating vitiligo.Methods According to the theory of local skin suction blister: local skin suction blister is decided by the two facts of the negative pressure and temperature,the skin suction blister apparatus was manufactured based on feedback principle,and was applied to autologous epidermal grafting for treating vitiligo.Results The performance of skin suction blister apparatus was stable,the operation was relative simple,and the total survival grade of autologous epidermal grafting was 98.01%.Conclusion The skin suction blister apparatus is simple to operate and its curative effect is excellent for clinical application.
