Effects of Mobile Text Advertising on Consumer Purchase Intention: A Moderated Mediation Analysis.

Mobile shopping is increasing in prevalence and has become a necessary part of many people's daily lives. However, one main channel for mobile shopping, mobile shopping applications (apps), has not been thoroughly investigated. This study focused on mobile text advertising delivered from mobile shopping apps using the intention to purchase as the dependent variable for testing its marketing effect. In the context of a promotion focus vs. a prevention focus, we used Higgins' regulatory focus theory combined with Ajzen's TPB and Herzog's U&G to analyze the mechanism by which consumers formulate an intention to purchase in a mobile advertising context. This empirical study surveyed 320 consumers who had made a purchase using a mobile shopping app in the previous month. The results showed that infotainment, irritation, and subjective norms were significantly associated with attitudes; in turn, attitudes mediated the impact of these three factors on the intention to purchase. Moreover, a high promotion focus not only strengthened the positive effect of infotainment on attitudes but also intensified the mediation effect of attitudes between infotainment and the intention to purchase. A high prevention focus also consolidated the negative effect of irritation on attitudes as well as reinforced the mediation effect of attitudes between irritation and the intention to purchase. Furthermore, attitudes, subjective norms, and perceived behavioral control collectively impacted the intention to purchase. These findings shed light on ways to customize goods information in mobile advertising and have strong theoretical and practical implications.

Simulation of the spatial and temporal changes of complex non-point source loads in a lake watershed of central China.

In this study, a coupling model of agricultural and urban non-point source (AUNPS) is established in order to estimate complex non-point source (NPS) pollutant loads in the urban-rural fringe. Furthermore, a spatial-temporal change model of non-point source (CA-AUNPS) is established by the coupling of AUNPS and cellular automata (CA) models. The total nitrogen (TN) and total phosphorus (TP) loads in Tangxun watershed were simulated during 1991-2020, and the results show that: (1) the CA-AUNPS model is an effective tool to simulate the spatial-temporal changes of NPS pollutant loads in urban-rural fringe; (2) in terms of the spatial changes, the TN and TP loads generally showed as rural/urban construction land > farmland > forest/green land, and the high-value areas of NPS pollutant loads expanded from north to south with the increase of construction land; with regard to temporal changes, the TN and TP loads generally displayed an increasing tendency during 1991-2020, and by 2020 the TN and TP loads will increase to 370.06 and 33.89 t yr(-1), respectively; (3) the spatial-temporal changes of TN and TP loads in Tangxun watershed correlate strongly with the land-use, slope, and rainfall.

The effect of butylphthalide on plasma brain-type creatine kinase isoenzyme,endothelin and calcitonin gene related peptide in patients with acute cerebral infarction / 中国医师进修杂志

ObjectiveTo explore the correlation between butylphthalide and plasma brain-type creatine kinase isoenzyme (CK-BB),endothelin (ET),calcitonin gene related peptide (CGRP) in patients with acute cerebral infarction (ACI).MethodsSixty patients with ACI were divided into treatment group and control group with 30 cases each by random digits table method.Both groups received normal treatment continuously for 7 days,and butylphthalide of 200 mg was added to treatment group for 3 times per day.The levels of plasma CK-BB,ET and CGRP of two groups before and after treatment were measured and compared.ResultsThe levels of plasma CK-BB,ET of two groups both decreased significantly after treatment,but CGRP rose obviously.It showed significant differences before and after treatment of both groups (P ＜0.01 or ＜ 0.05).The levels of plasma CK-BB,ET of treatment group after treatment were lower than those of control group in the same period [(216.48±36.95) U/L vs.(333.07±54.03) U/L,(83.33±26.48)ng/L vs.(98.46±31.46) ng/L,P ＜ 0.05 ].The level of plasma CGRP of treatment group after treatment was significantly higher than that of control group in the same period [ (44.16±13.28 ) ng/L vs.(36.42±12.31 )ng/L,P ＜ 0.05 ].ConclusionButylphthalide can reduce the plasma enzyme activity,balance ET and CGRP,extend the cerebral arteries to antagonize ET,improve cerebral ischemia and cerebral hypoxia,which can protect brain cells and endothelial cells.

Impact Factors on Nosocomial Respiratory Tract Infections after Operations under General Anesthesia with Tracheal Intubation / 中华医院感染学杂志

OBJECTIVE To probe into the impact factors of the nosocomial respiratory tract infections after the operations with tracheal intubation under general anesthesia in order to establish the prevention and treatment strategies and provide the scientific basis.METHODS By descriptive epidemiological method and case-control study method,80 cases with nosocomial respiratory tract infections in nearly 3 years who had tracheal intubation under general anesthesia were selected,and another 180 patients with non-nosocomial respiratory tract infections with tracheal intubation under general anesthesia were selected as the control.RESULTS The incidence of the nosocomial infections from 5923 patients of the operation with tracheal intubation under general anesthesia from 2005 to 2007 accounted for 10.1%.The incidence of the respiratory tract infections of operations under general anesthesia accounted for 5.25%.The nosocomial respiratory tract infection from the tracheal intubation under general anesthesia toped the list and accounted for 52.0%.It showed seven impact factors on the nosocomial respiratory tract infection after the operation with tracheal intubation under general anesthesia by the multi-factorial Logistic regression,respectively,with significant differences(P1).CONCLUSIONS There are many impact factors that the nosocomial respiratory tract infection(especially lower respiratory tract infection) resulting from the operation with tracheal intubation under general anesthesia.The study shows the main risk factors: age,the complications of the disease,surgical condition,the ventilation time of tracheal intubationunder the anesthesia,post-operative recovery time,smoking status,the time that the operated patients start coughing after the operation.Therefore,the prevention is especially important.

Antibiotics Clinical Usage in General Hospital / 中华医院感染学杂志

OBJECTIVE To investigate the usage of antibiotics for improving the management and proper clinical utilization. METHODS The data of 781 inpatients had been analyzed by field survey in our hospital in July 27,2005.The data were analyzed by computer. RESULTS The rate of antibiotic usage was 56.98%,and the rate of preventive antibiotic usage was 20.74%.Cephalosporins were the first,quinolones were the next and then penicillins in the antibiotics usage.Only 33.57% infectious patients were made bacteria culture and antibiotics drug sensitive test.Most antibiotics were used according to clinical experience. CONCLUSIONS Most of the doctors can use antibiotics properly.The strengthening control and rational antibiotics usage in prevention are the key means to decrease the numbers of irrational application.

Changes of Antibiotic Resistance Spectra of 3 Non-fermental G~- Bacteria in Recent 4 Years in Our Hospital / 中国药房

OBJECTIVE:To study the change of antibacterial resistance spectra of3non-fermental G - bacteria in our hospital during recent4years,so as to guide the rational use of antibacterial.METHODS:Pseudomonas aeruginosa,acineto?bacter baumanii,stenotrophomonas maltophilia were isolated from clinical samples in our hospital from July2001to June2005,the susceptibility of these isolates were tested by Kirby-Bauer agar diffusion method,data were analyzed by WHONET5.RESULTS:598strains of P.aeruginosa,281strains of A.baumanii and209strains of S.maltophilia were obtained during4years.Now the resistance rates of ceftazidime,amikacin,cefoperazone/sulbactam and imipenem to P.aeruginosa were lower than30%;A.baumanii were sensitive to imipenem,the other antibiotic resistance rates were more than50%;The antibiotic resistance rate of S.maltophilia to ofloxacin and trimethoprim/sulfamethoxazole was relatively low?er.CONCLUSIONS:The antibiotic resistance rates of non-fermental G - bacteria are high and display multiple-resistant.It's important to monitor the antibiotic resistance periodically to guide clinical antibiotics use.
