Objective To identify the potential correlation of serum 25-hydroxyvitamin D3 [25 (OH)D3]and C-reactive protein (CRP) with coronary artery disease.Methods We measured the serum 25 (OH)D3 and CRP levels in 416 suspected coronary heart disease patients who underwent coronary angiography.Gensini scores were used to assess the severity of coronary stenosis.Based on the results of coronary angiography,the 416 patients were divided into normal group (n =246),stable angina group (n =110),and acute coronary syndrome (ACS) group (n =60).Results The serum levels of 25 (OH) D3 in the normal group and stable angina group were significantly higher than that in the ACS gropu [(33.15 ± 20.95) nmol/L vs.(15.55 ±5.7) nmol/L,(28.93 ± 16.45) nmol/Lvs.(15.55 ± 5.7) nmol/L,bothP＜0.001].TheCRPlevelin the normal group was significantly lower than those in the stable angina group and the ACS group [(4.33 ± 0.12) rng/Lvs.(5.68 ± 0.25) mg/L,(4.33 ± 0.12) mg/Lvs.(5.73 ± 0.31) mg/L,bothP＜0.001].The serum 25 (OH)D3 was not correlated with CRP or Gensini score in the normal group.In the ACS group,the serum 25 (OH) D3 was negatively correlated with CRP level and Gensini score (r =-0.026,P =0.045 ; r =-0.256,P =0.048),while CRP level was positively correlated with Gensini score (r =0.459,P ＜0.001).Inthe stable angina group,the serum 25 (OH)D3 was also negatively correlated with CRP level and Gensini score (r =-0.211,P =0.027; r =-0.208,P =0.029),and the latter two were positively correlated (r =0.574,P ＜ 0.001).Conclusions Low serum 25 (OH) D3 levels are associated with coronary artery stenosis.Combining with CRP,it may be involved in the pathogenesis of coronary heart disease through inflammatory mechanism.

OBJECTIVE:To investigate the effects of Astragalus injection combined with Salmeterol propionate powder inhala-tion on pulmonary function,cytokines and blood rheology indexes of Chronic obsrnctine pulmonary disease (COPD) patients. METHODS:104 COPD patients were divided into observation group and control group according to the randorn number table meth-od,with 52 cases in each group. Control group was given routine symptomatic treatment+Salmeterol propionate powder inhalation 1 dose,bid;observation group was additionally given Astragalus injection 30 ml added into 5% Glucose injection 250 ml,ivgtt, qd,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. Clinical efficacy,pulmonary function indexes [forced expiratory volume in one second(FEV1),forced vital capacity(FVC),FEV1/FVC],CRP,cytokine [IL-6,IL-8,TNF-α] levels,blood rheology indexes (whole blood high-shear viscosity,whole blood low-shear viscosity,fibrinogen,hematokrit and plasma viscosity),and the occurrence of ADR were observed in 2 groups. RESULTS:The total effective rate of observation group (94.23%)was significantly higher than that of control group(75.00%);compared with before treatment,FEV1,FVC and FEV1/FVC of 2 groups were significantly increased after treatment,and those of observation group were significantly higher than those of control group;CRP,IL-6,IL-8 and TNF-α of 2 groups were significantly decreased,and those of observation group were signifi-cantly lower than those of control group. The whole blood high-shear viscosity,whole blood low-shear viscosity,fibrinogen,hema-tocrit and plasma viscosity of observation group were decreased significantly after treatment,and the observation group was signifi-cantly lower than the control group,with statistical significance(P<0.05). No significant ADR was found in 2 groups. CONCLU-SIONS:Astragalus injection combined with Salmeterol propionate powder inhalation is significantly effective for COPD,improves pulmonary function of patients,improves micro inflammatory state and decreases blood rheology indexes with good safety.

Aim To investigate the role of mitochondrial aldehyde dehydrogenase 2 ( ALDH2) in the cardio-protection of ischemic postconditioning in isolated rat hearts. Methods Hearts isolated from male Sprague-Dawley rats were perfused on a langendorff apparatus and subjected to 30 min of regional ischemia( occlusion of left anterior descending artery) followed by 120 min reperfusion. Ischemic postconditioning was achieved by 6 cycles of 10 s reperfusion/10 s global ischemia starting at the beginning of reperfusion. The ventricular hemodynamic parameters and lactate dehydrogenase ( LDH) release during reperfusion were measured. The infarct size was measured by TTC staining method. The expressions of ALDH2,Bcl-2 and Bax at mRNA level of left anterior myocardium were detected by RT-PCR analysis. Results In contrast to ischemia and reperfusion,ischemic postconditioning improved the recovery of left ventricular developed pressure,rate pressure product during reperfusion,and reduced LDH release and infarct size. The expressions of ALDH2 mRNA level and the ratio of Bcl-2 /Bax were increased. Adminis-tration of ALDH2 antagonist cyanamide at the beginning of reperfusion attentuated the role of ischemic postconditioning. Conclusion Ischemic postconditioning plays a role in the cardioprotection partially through increasing mitochondrial ALDH2 mRNA expression.

OBJECTIVETo understand the epidemiological characteristics of head injuries in children.

METHODSData was derived from the Chinese National Injury Surveillance System (NISS) in 2014. Method on descriptive analysis was applied to depict general information, injuries events and clinical characteristics of head injuries among children under 18 years of age.

RESULTSA total number of 47 690 cases with child head injuries in 2014 were collected, including 32 542 males and 15 148 females. 43.47% of them were under 1-4 years of age. In October, 06:00 PM appeared the peak time for the injuries to happen. The three leading causes responsible for child head injuries were falls (69.57%), hit by blunt force (14.23%) or road traffic (11.01%). Main locations responsible for the head injuries to happen were:at home (44.98%), at public places (19.65%) or on roads/streets (15.81%). Recreation activates (77.88%), driving (7.32%), sports (5.72%) were the three major activities causing the injuries to take place. Majority of the cases happened unintentionally (95.35%), with bruise (71.69%) or mild injuries (85.27%) and went back home after treatment (90.25%).

CONCLUSIONSIn 2014, child head injuries were seen more in males than in females and mostly occured at home. The leading causes for head injuries would include falls, hit by blunt stuff or road traffic .

The number of articles in anesthesia nursing field was relatively small in first 30 years,increasing year by year since 1970s and speeding up since 1990s.The average number of articles from 2012-2017 was all above 150.The 5,041 articles distributed in 1,260 journals.The top 10 journals accounted for 24.36% of the total number (1228/5041).The articles were mainly published in the developed countries in Europe and America.The hot spots in anesthesia nursing research included anesthesia management and pain management,professional skills of anesthesia nurses and medical team collaboration,intervention on psychological status and complications among perioperative patients. Conclusions The research of anesthesia nursing aboard has attracted more and more attention and formed several research highlights.Domestic research in the field is still at the early stage and in the future,domestic scholars can draw on foreign research highlights to carry out relevant research.

Objective: To analyze and compare the disease burden of falls in Chinese population aged 0-19, in 1990 and 2017. Methods: Indicators including number of deaths, mortality rates, years of life lost due to premature mortality (YLL), years lived with disability (YLD) and disability-adjusted of life years (DALY), on falls, were gathered from the Global Burden of Disease (GBD) 2017 and used to describe the disease burden and corresponding parameters on falls, between 1990 and 2017, in China. Results: In 2017, number of death, YLLs, YLDs, DALYs caused by falls were 5 321, 0.43 million person years, 0.14 million person years and 0.57 million person years respectively, among aged 0-19 group. Rates on standardized mortality, YLLs, YLDs and DALYs on falls were 1.76/100 000, 141.49/100 000, 46.99/100 000, and 188.48/100 000, respectively. The burden of falls decreased with the increase of age. Compared with 1990, disease burden of falls decreased in all age groups, both in male and female, with more seen in the lower age groups. Compared with 1990, the number of deaths, rates on YLLs, YLDs and DALYs caused by falls decreased by 65.08%, 46.63%, 47.38% and 36.33% respectively, in 2017. However, the YLDs rate increased by 73.31% between 1990 and 2017. The ratio of YLLs to DALYs decreased from 90.84% in 1990 to 75.07% in 2017, with a proportion as 17.36%. Conclusion Compared with 1990, although the disease burden of falls among aged 0-19 group showed a decreasing trend, falls still caused serious disease burden for the aged 0-19 group. Research that targeting prevention on falls, should be continued.

Objective: To understand the current situation of road traffic injuries among primary and secondary school students in Mengzi city. Methods: Using the cluster random sampling method, more than 9 000 primary and secondary school students from 20 primary and secondary schools in Mengzi city, were randomly sampled. A questionnaire survey was conducted on the occurrence of road traffic injuries in school students. Results: A total of 9 197 students were surveyed, including 150 from road traffic injuries. The incidence rates of road traffic injuries was 1.63% among students in Mengzi city and 2.85% among junior high school students, with the high incidence in May. The leading places of injuries were village roads (38.00%), city roads (33.33%) and district roads (12.67%), respectively. 26.67% of the traffic injuries occurred on the way to or from schools, with riding on electric bicycle (52.00%) as the major cause and contusion/abrasion (75.33%) appeared as the major signs. Both lower and upper limbs plus multiple parts were accounting for 45.51%, 22.16% and 16.17%, respectively of all the injuries. 70.67% of all the cases with road traffic injuries in children, recovered after treatment. Children with road traffic injuries would stay in the hospital for up to 90 days but spent less than 30 000 Yuan. Conclusion The incidence of road traffic injuries among students in Mengzi city seemed relatively high, with junior high school students reached the highest. Riding electric bicycle appeared as the leading cause for traffic injuries in children in Mengzi city of Yunnan province.
