Objective To investigate the early alterations of neurometabolites in the splenium of corpus callosum by proton magnetic resonance spectroscopy (~1H-MRS) in patients with diffuse axonal injury (DAI) at early stage and their prognostic value. Methods Twenty-one patients with DAI underwent 1H-MRS examination in the splenium of corpus callosum 2 to 14 d after injury, the neurometabolite alterations were evaluated and compared with those of 10 healthy subjects (normal controls). Logistic regression analysis was performed to explore the correlation among neurometabolite alterations, clinical indexes and Glasgow outcome scale (GOS) six months after injury. Results There was a significant decrease in NAA/Cr and NAA/Cho and increase in Cho/Cr in the splenium of corpus callosum in patients with DAI as compared with control group (P<0.05), and these trends tended to be more evident with the increase of injury severity. NAA/Cr and NAA/Cho in patients with poor outcomes were lower than those in patients with good outcomes (P<0.05). NAA/Cr, NAA/Cho and Cho/Cr predicted long-term outcome with 89% accuracy, and the combination with GOS provided the predictive accuracy of 94%. Conclusion ~1H-MRS examination in the splenium of corpus callosum at early stage of DAI can depict brain injury severity, and is useful in predicting outcomes.

Objective To explore the application of micro-lecture in the health education of patients with osteoporosis combined with spinal tuberculosis.Methods By convenient sampling method, 102 patients with spinal tuberculosis and osteoporosis of a tertiary hospital of Beijing were selected from January 2014 to January 2016. They were divided into the control group (n=52) and the observation group (n=50). Patients in the control group received routine health education, while patients in the observation group were given micro-lecture. Health education knowledge and satisfaction to health education of patients in two groups were compared.Results Before discharge, the score of health education questionnaire in the observation group was higher than that of the control group, in which cognition was (3.97±0.82), operation (4.03±0.78), emotion (4.04±0.79); there were statistically significant differences between two groups (t=4.295,4.996,4.732;P<0.01). The score of satisfaction to health education in the observation group was (96.88±2.14), and in the control group was (90.96±5.79) (t'=6.899,P<0.01).Conclusions Micro-lecture in health education for patients with spinal tuberculosis combined with osteoporosis get good effect, and it plays a positive role in the treatment and extended care of hospitalized patients.

OBJECTIVETo understand the epidemiological profiles of hand, foot and mouth disease (HFMD) and the major enteroviruses causing the epidemics of HFMD in Shanghai from 2010 to 2014.

METHODThe city-wide surveillance data between 2010 and 2014 were used to analyze the epidemiologic characteristics of the HFMD outbreaks in Shanghai. The annual incidence of HFMD was estimated based on the 2010 Shanghai Census data.

RESULTFrom 2010 to 2014, the reported HFMD cases were 41 080, 37 323, 51 172, 42 198, and 65 018, respectively; the severe cases (case-severity ratio) were 469 (1.14%), 456 (1.22%), 318 (0.62%), 104 (0.25%) and 248 (0.38%), respectively. Based on Shanghai census data by the end of 2010, the attack rates of HFMD in Shanghai were 0.16%-0.28% in the entire population. In terms of the proportion of HFMD cases and severe cases in the specific population, male accounted for 59.62%-61.48% and 62.26%-73.08%, migrant population accounted for 51.86%-62.40% and 72.01%-80.38%; children aged 1.0-1.9 years comprised the highest proportion, up to 22.70%-27.00% and 32.08%-36.40%. HFMD peaked from April to July, in parallel with the peak circulation of enterovirus (EV) 71, and a small peak usually occurred in autumn and winter. All the critically severe and fatal cases were caused by EV71. The detection rates of EV71 and Coxsackievirus A (CA) 16 were 73.08%-88.09% and 1.12%-2.90% in severe HFMD cases, 19.75%-48.74% and 2.02%-23.69% in uncomplicated inpatients, and 16.78%-40.08% and 8.36%-33.39% in mild community cases, respectively. The detection rates of CA6 and CA10 in the mild community cases in 2014 were 18.38% and 1.43%, respectively. In 2013 non-EV71 and non-CA16 enteroviruses comprised 74.86% in the community cases.

CONCLUSIONThe annual HFMD outbreaks occurred in Shanghai during 2010-2014. Children under 5 years of age, migrant population and male were the major susceptible population. EV71 and CA16 were the predominant pathogens causing the epidemics of HFMD except in 2013, and CA6 was prevalent in the community cases in 2014. The major peak season of HFMD usually overlapped with the peak of EV71 circulation and the majority of severe HFMD cases were associated with EV71 infection.
