PURPOSE: This study was performed for investigation of epidemiology, clinical characteristics, and serial value of cardiac troponin level of patients who had myocardial injury due to Carbon monoxide poisoning. METHODS: This study reviewed 98 cases of Carbon monoxide poisoning patients who visited Emergency Department from January 1, 2008 to October 31, 2013. We categorized them by two groups, one with elevation of cardiac troponin level and the other with normal level. We had comparison between two groups data using statistical analysis. RESULTS: Among 98 patients of Carbon monoxide poisoning who were admitted to hospital, 10 patients were excluded. 88 patients who were included to our study, 70 patients with normal value of Troponin, and 18 patients with elevated troponin level. Of all patients, Carbon monoxide inhalation due to suicided trial patients has more higher proportion in elevated troponin level group compared with normal group (40 (57.1%) vs 15 (83.3%), P=0.041). Furthermore, corrected QT interval, length of hospital stay, number of ICU admission, also were showed higher value in elevated troponin level group. CONCLUSION: Carbon monoxide induced myocardial injury is associated with subside trial, prolongation of correted QT interval, length of hospital stay, and number of ICU admission.

OBJECTIVE:
This study aimed to determine the spatiotemporal distribution and epidemiological characteristics of hospital admissions for carbon monoxide poisoning (COP) in Guangdong, China, from 2013 to 2020.
METHODS:
Data on age- and sex- specific numbers of hospital admissions due to COP in Guangdong (2013-2020) were collected. Daily temperatures were downloaded through the China Meteorological Data Sharing Service System. We analyzed temporal trends through time series decomposition and used spatial autocorrelation analysis to detect spatial clustering. The distributed lag nonlinear model was used to quantify the effects of temperature.
RESULTS:
There were 48,854 COP admissions over the study period. The sex ratio (male to female) was 1:1.74. The concentration ratios (M) ranged from 0.73-0.82. The highest risk occurred in January (season index = 3.59). Most cases were concentrated in the northern mountainous areas of Guangdong with high-high clustering. COP in the study region showed significant spatial autocorrelation, and the global Moran's Ivalue of average annual hospital admission rates for COP was 0.447 ( P < 0.05). Low temperatures were associated with high hospital admission rates for COP, with a lag lasting 7 days. With a lag of 0 days, the effects of low temperatures [5th (12 °C)] on COP were 2.24-3.81, as compared with the reference temperature [median (24 °C)].
CONCLUSION
COP in Guangdong province showed significant temporal and spatial heterogeneity. Low temperature was associated with a high risk of COP, and the influence had a lag lasting 7 days.

OBJECTIVE:
To provide references for forensic expertise by investigating the kinds of toxicant, routes of exposure and manners of poisoning deaths, etc.
METHODS:
Six hundred and seven autopsy cases of poisoning deaths from 1957 to 2008 in Department of Forensic Medicine, Tongji Medical College (Tongji Forensic Science Identification Center of Hubei), were comparatively reviewed.
RESULTS:
In 218 cases from 1999 to 2008, more than 50% of decedents were male in the ages of 30-49. The toxicants are usually taken orally and the most common manner of death was accidental. The common substances involved in poisoning death were rodenticide, poisoning gas and insecticide. Compared to the data of 1983-1998 and 1957-1982, the common toxic agents had changed significantly. The number of cases involving insecticide and cyanide poisoning decreased in recent years, and the number of cases of rodenticide, poisoning gas, alcohols poisoning displayed an increase tendency, especially for drugs abuse.
CONCLUSION
Poisoning deaths of pesticides remain a major public health problem for a long time and the awareness of prevention need to be raised, especially for the prevention of deaths from multiple poisons.

Objective: To investigate the poisonous substances and geographical distribution of poisoning in children in China. Methods: A cross-sectional study. The clinical data of 8 385 hospitalized children from January 2016 to December 2020 were extracted from the FUTang Updating Medical Records database. These children aged 0 to 18 years and were admitted due to poisoning. They were grouped according to age (newborns and infants, toddlers, preschoolers, school-age children, adolescents), place of residence (Northeast China, North China, Central China, East China, South China, Southwest China, Northwest China), and mode of discharge (discharge under medical advice, transfer to another hospital under medical advice, discharge without medical advice, death, other). The poisonous substance and causes of poisoning in different groups were analyzed. Results: Among these 8 385 children, 4 734 (56.5%) were male and 3 651 (43.5%) female, with a male-to-female ratio of 1.3∶1. The age was 3 (2, 7) years. The prevalence of poisoning was 51.8% (4 343/8 385) in toddlers, 16.5% (1 380/8 385) in adolescents, 14.8% (1 242/8 385) in preschoolers, 14.4% (1 206/8 385) in school-age children, and 2.5% (214/8 385) in newborns and infants. Drug poisoning accounted for 43.5% (3 649/8 385) and pesticide accounted for 26.8% (2 249/8 385). Drug poisoning was more common in adolescents (684/1 380, 49.6%) and toddlers (2 041/4 343, 47.0%); non-drug poisoning was more common in school-age children (891/1 206, 73.9%), of which carbon monoxide was mainly in newborns and infants (41/214, 19.2%) and food poisoning in children of school age (241/1 206, 20.0%). Regarding regional characteristics, drug poisoning was more frequent in South China (188/246, 64.2%) and non-drug poisoning was more frequent in Southwest China (815/1 123, 72.5%). For drugs, anti-epileptic drugs, sedative-hypnotic drugs and anti-Parkinson's disease drugs had a higher proportion of poisoning in North China (138/1 034, 13.0%) than that in other regions. For non-drug poisoning, pesticides (375/1 123, 33.3%), food poisoning (209/1 123, 18.6%) and contact with poisonous animals (86/1 123, 7.7%) were more common in Southwest China than in other regions; carbon monoxide poisoning was more common in North China (81/1 034, 7.6%) and Northwest China (65/1 064, 6.3%). In Central China, poisoning happened more in toddlers (792/1 295, 61.2%) and less in adolescents (115/1 295, 8.8%) than in other regions. Regarding different age groups, poisoning in adolescent happened more in Northeast China (121/457, 26.5%), North China (240/1 034, 23.2%), and Northwest China (245/1 064, 23.0%). The rate of discharge under medical advice, discharge without medical advice, and mortality rate within the 5 years were 77.0% (6 458/8 385), 20.8% (1 743/8 385), 0.5% (40/8 385), respectively. Conclusions: Poisoning is more common in male and toddlers. Poisonous substances show a regional characteristic and vary in different age groups, with drugs and insecticides as the most common substances.
