Objective Health belief model and theory of reasoned action or theory of planned behavior have been used widely in studies of health behavior and combined to use in many studies to explain and predict definite health behaviors.A systematic review was conducted to analyze how two theories combined in the studies related to health behaviors,to explore general factors influencing different health behaviors,and so that to provide evidence for future health promotion and health education strategies.Methods Nine databases were searched using predetermined search strategies and 322 indexes were identified.Key information of included studies was extracted and the quality of each one was assessed according to Strobe Checklist and Cochrane Handbook for Systematic Reviews of Interventions.Results 40 papers including 37 studies were finally included in this review.6 studies were of high quality,while others were of medium quality.Most studies were cross-sectional survey.Two theories were usually as the framework basis and used to develop research instruments in the included studies.Some researchers used behavioral intention as an outcome variable instead of actual behavior.Subjective norms,perceived susceptibility,and perceived behavior control were the most influencing factors for behavioral intention;perceived barriers,behavioral intention,and perceived behavior control were the most influencing factors for behavior.Conclusions There are some limitations need to avoid in the future studies synthetically using HBM and TRA/TPB.Improving individuals' perceived susceptibility and subjective norms by extending the target population can serve as the common intervention to change health behaviors;further studies should identify individuals' perceived barriers and control beliefs of specific behaviors,and make responding interventions.

Methods:Chinese hamster lung(CHL) cell culture was carried out in vitro.Cells were exposed to extracts of dominant indoor airborne fungal culture,then MTT method and CHL colonies assay were performed to detect their cytotoxicity.The release of cytosolic enzyme Lactate Dehydrogenase(LDH) and the fluidity of K~+,Ca~(2+) were analysed. Results:With the increase of the dose,the LDH levels in culture medium increased and the Ca~(2+) concentration inside cells increased while the K~+ concentration inside cells decreased accordingly. Conclusion:The extracts of dominant indoor airborne fungal culture could damage cell membrane,and have cytotoxicity.

Objective To observe the relationship between the levels of plasma VEGF,PAI-1 and the severity of the diabetic retinopathy in type 2 diabetic patients.Methods ELISA method was used to measure the levels of VEGF and PAI-1.Results The level of VEGF was increased in all diabetic patients compared with the normal control group[(17.86?12.25)ng/L],and that of the patients with BDR[(93.41?54.69)ng/L]was higher than that of the patients with NDR[(52.17?21.81)ng/L]and PDR[(61.24?37.55)ng/L].The level of PAI-1 was also increased in all diabetic patients.The increase tendency was more obvious in patients with BDR[(58.29?20.53)?g/L]and PDR[(66.84?23.81)?g/L].Conclusion The damage of the vascular endothelial cell and the impaired fibrinolysis state exist in diabetic retinopathy.So it is very important to measure the levels of VEGF and PAI-1 for the early diagnosis and intervention treatment of diabetic retinopathy.

Plague is an animal-sourced infectious disease of caused by Yersinia pestis, listed asa Class A notifiable infectious disease in China and an international quarantine infectious disease. It has caused three plague world pandemics in human history. Currently, the natural plague foci are distributed in all continents except Antarctica and Oceania. Madagascar and the Democratic Republic of the Congo (DRC) currently have the highest level of human plague epidemic in the world. In the middle of 20th century, human plague was prevalent in China, with an average of 1 400.8 reported cases per year from 1950 to 1954. After 1955, large-scale outbreaks of human plague were effectively controlled, with an average of 24.7 reported cases per year from 1955 to 1999. From 2000 to the present, human cases have not yet disappeared with a cumulative total of 514 cases had been reported. The plague control strategy based on the One Health concept is a more optimal solution, mainly reflected in the "ecological animal surveillance" and "early diagnosis and disposal of human cases" dual approach. Effective animal surveillance can provide accurate prediction and early warning of the risk that may be spread to humans, while early diagnosis and early treatment of human cases can availably control the spread of the epidemic and effectively reduce the case fatality rate simultaneously.

Objective To study the clinical value of bedside ultrasound in predicting the fluid responsiveness in pa?tients with septic shock in intensive care unit (ICU). Methods Forty-two mechanically ventilated patients with septic shock who admitted to ICU of the Affiliated Hospital of North China University of Science and Technology from January 2015 to April 2015 were included in this study. All patients were treated with volume expansion (VE) text. Hemodynamics in?dexes were obtained by ultrasound before and after each test, including stroke volume (SV), aortic peak blood flow velocity variation rate of breathing (△VpeakAO), inferior vena cava expansion index (△IVC) and brachial artery maximum speed vari?ation rate (△VpeakBA). Clinical data and central venous pressure (CVP) were recorded. Based on the responsiveness of SV, patients were divided into responsive group (R) and non-responsive group (NR), respectively. The differences of the above in?dexes were compared between two groups. The correlation of△IVC,△VpeakAO,△VpeakBA and△SV was determined. The role of the hemodynamic index for predicting volume responsiveness was evaluated by receiver operating characteristic ROC curves. Results A total of 47 VE tests were performed in 42 patients, 25 in R group and 22 in NR group. Before VE test, the hemodynamics indicators of△IVC,△VpeakAO and△VpeakBA were significantly higher in R group compared with those of NR group (P<0.05). The values of△IVC,△VpeakAO and△VpeakBA were positively correlated with△SV in two groups. The areas under the ROC curve of the hemodynamics indicators were 0.825, 0.853 and 0.866 for △IVC, △VpeakAO and△VpeakBA, and they all showed high sensitivity and specificity. Conclusion The hemodynamic index measured by bedside ultrasound can predict the volume responsiveness in mechanically ventilated patients with septic shock fluid therapy, and which can be used to fluid therapy with a high degree of specific and sensitivity in clinical practice.

Objective: To investigate the ultrasound evaluation on lfuid responsiveness in patients with septic shock. Methods: There 42 septic shock patients treated by mechanical ventilation in our hospital from 2015-01 to 2015-04 were studied. All patients received volume expansion (VE) text, ultrasound examination was conducted to measure hemodynamic parameters of inferior vena cava variation rate of breathing (ΔIVC), aortic peak blood lfow velocity variation rate of breathing (ΔVpeakAO), brachial artery maximum speed variation rate (ΔVpeakBA) and stroke volume (ΔSV) at before and after text. Based on the response to VE text, the patients were divided into 2 groups as Responsive group and Non-responsive group, the above indexes and their correlations to ΔSV were analyzed. The clinical values of those parameters for predicting volume responsiveness were evaluated by ROC curves. Results: A total of 47 VE tests were conducted in 42 patients including 25 cases in Responsive group and 22 cases in Non-responsive group. Before VE test, the parameters of ΔIVC, ΔVpeakAO and ΔVpeakBA were higher in Responsive group than Non-responsive group; ΔIVC, ΔVpeakAO and ΔVpeakBA were obviously related to ΔSV (r=0.631, 0.668 and 0.619). The area of ΔIVC, ΔVpeakAO and ΔVpeakBA under ROC curves were 0.817, 0.853 and 0.866 respectively, they were all with the high sensitivity and speciifcity. Conclusion: Ultrasound monitored hemodynamic parameters may predict the volume responsiveness in septic shock patients with mechanical ventilation, it could be used for guiding liquid treatment in relevant patients.

The literature analysis and case analysis were used to analyze the current situation and problems of the patent protection of Chinese medicine.The patent of artemisinin was registered abroad as the failure case, while Tasly developed the construction of the patent net overseas as a successful case. The intellectual property right of traditional Chinese medicine has started late in China, so the Chinese pharmaceutical enterprises lacked awareness of the intellectual property protection of Chinese medicine, and it is difficult for us to have comprehensive intellectual propertyright protection in traditional Chinese medicine. The intellectual property system of Chinese medicine in China needs improvement.
