ABSTRACT
Objective To explore the impact of severe weather on road traffic injuries (RTIs). Methods Relevant literature on the impact of meteorology on the occurrence and resulting casualties of road traffic injuries was searched. Meta-analysis was performed on the included literature using state16.0 software. Results A total of 28 articles were included. The results of meta-analysis showed that heat wave, cloudy day, snowy day, rainy day and other severe weather such as storm had a statistically significant impact on the occurrence of road traffic injuries. Severe weather such as storms had a statistically significant impact on RTIs casualties. Conclusion Heat wave, cloudy day, snowy day, rainy day, storm and other bad weather are independent risk factors for the occurrence of RTIs. Storm is a risk factor for accident casualties. There is not enough evidence to show that low temperature, cold wave and heavy fog are the influencing factors of road traffic accidents.
ABSTRACT
@#Objective To construct a prognostic model of esophageal squamous cell carcinoma (ESCC) based on immune checkpoint-related genes and explore the potential relationship between these genes and the tumor microenvironment (TME). Methods The transcriptome sequencing data and clinical information of immune checkpoint genes of samples from GSE53625 in GEO database were collected. The difference of gene expression between ESCC and normal paracancerous tissues was evaluated, and the drug sensitivity of differentially expressed genes in ESCC was analyzed. We then constructed a risk model based on survival-related genes and explored the prognostic characteristics, enriched pathway, immune checkpoints, immune score, immune cell infiltration, and potentially sensitive drugs of different risk groups. Results A total of 358 samples from 179 patients were enrolled, including 179 ESCC samples and 179 corresponding paracancerous tissues. There were 33 males and 146 females, including 80 patients≤60 years and 99 patients>60 years. 39 immune checkpoint genes were differentially expressed in ESCC, including 14 low expression genes and 25 high expression genes. Drug sensitivity analysis of 8 highly expressed genes (TNFRSF8, CTLA4, TNFRSF4, CD276, TNFSF4, IDO1, CD80, TNFRSF18) showed that many compounds were sensitive to these immunotherapy targets. A risk model based on three prognostic genes (NRP1, ICOSLG, HHLA2) was constructed by the least absolute shrinkage and selection operator analysis. It was found that the overall survival time of the high-risk group was significantly lower than that of the low-risk group (P<0.001). Similar results were obtained in different ESCC subtypes. The risk score based on the immune checkpoint gene was identified as an independent prognostic factor for ESCC. Different risk groups had unique enriched pathways, immune cell infiltration, TME, and sensitive drugs. Conclusion A prognostic model based on immune checkpoint gene is established, which can accurately stratify ESCC and provide potential sensitive drugs for ESCC with different risks, thus providing a possibility for personalized treatment of ESCC.
ABSTRACT
Objective@#To describe the mortality trend of major malignant tumors in Shandong province, from 1970 to 2013.@*Methods@#Data related to cancer mortality were obtained from the Shandong Death Registration System and three nationwide retrospective cause-of-death surveys. Trends of overall mortality and major causes of death were described using the indicators as: mortality rates and age-standardized mortality rates, through comparing the three large-scale mortality surveys in Shandong province. Difference decomposing method was applied to estimate the contribution of demographic and non-demographic factors for the change of mortality.@*Results@#From 1970 to 2013, the crude mortality rate of malignant tumors in Shandong was increasing. The age standard mortality rate was increasing and then decreasing. The composition of cancer deaths in the all-cause-deaths was seen increasing and then decreasing as well. Both demographic and non-demographic factors contributed to the increase of crude cancer mortality rate. With the gradual increase of the proportion of population, its role exceeded the non-demographic factors. The age-standardized mortality rate of malignant tumors in 2011-2013 was lower than that in 2004-2005. Lung cancer mortality rose from the fifth to the first place, with an increase of 6.81 times from 1970-1974 to 2011-2013. Ranking of gastric cancer mortality dropped from first to the third place, with esophageal cancer dropped from second to the fourth. After adjusted by China’s standard population in 1964, the mortality rate of lung cancer was still rapidly increasing, but the age-standardized mortality rates of esophageal cancer was gradually decreasing. The crude and age-standardized mortality rates of cervical cancer showed a rapid downward trend, reduced 87.00% and 93.00% respectively from 1970-1974 to 2011-2013.@*Conclusions@#Malignant tumors were still major threats to the residents of Shandong province. The changing trend of different malignant tumors presented an inconsistent nature which called for different intervention strategies be carried out, accordingly.
ABSTRACT
Based on the data from Shandong Province death registration system in 2015, the mortality rate was adjusted by the results of underreporting rate investigation, and the probability of premature death of non-communicable diseases was calculated by life table method. A total of 728 287 deaths caused by four main non-communicable diseases (NCDs) including cardiovascular and cerebrovascular diseases, malignant tumor, diabetes, and chronic respiratory disease, accounting for 85.83% of the total death in 2015. The death of cardiovascular and cerebrovascular diseases and malignant tumor accounted for 50.90% and 25.69% respectively. The probability of premature death was 17.84%. The probability in males was higher than that in females (23.12% vs 12.25%). The highest probability of premature death in urban was cancer, but in rural was cardiovascular and cerebrovascular diseases. The probability increased from the East areas to the West. The highest probability reached at 21.50% in the Western underdeveloped areas, and the lowest probability was in Dongying City (14.84%) and Weihai City (14.94%) in the coastal areas.

<p><b>OBJECTIVE</b>To compare the difference and correlation between dietary salt intakes assessed by 24 hours urinary Na method, food weighted record method and food frequency questionnaire method.</p><p><b>METHODS</b>All 2 184 subjects aged 18 to 69 were selected by multi stage stratified cluster random sampling method in Shandong province in June to September, 2011. Dietary salt intakes were measured by 24 hours urinary Na method, food weighted record method and food frequency questionnaire method. The information on gender, age, dining locations and labour intensity of members dining at home for 3 days were recorded. And the dietary habits were surveyed by questionnaire.</p><p><b>RESULTS</b>Salt intakes were 14.0, 12.0 and 10.5 g/d assessed by 24 hours urinary Na method, food weighted record method and food frequency questionnaire, respectively. Comparing with 24 hours urinary Na method, salt intakes assessed by food weighted record method and food frequency questionnaire method were 2.0 g (14.3% undervalued) and 3.4 g (24.3% undervalued) less, respectively. Comparing with 24 hours urinary Na method, the proportion of individuals with salt intake over-reported and under-reported were 42.4% (856/2 020) and 55.3% (1 117/2 020) by food weighted record method, and were 20.7% (418/2 020) and 16.3% (329/2 020) by food frequency questionnaire method, respectively; the proportion of individuals with salt intakes within ± 25% of 24 hours urinary Na method were 36.9% (745/2 020) and 28.4% (574/2 020), respectively. Salt intakes assessed by 24 hours urinary method correlated significantly with both salt intakes assessed by food weighted record method and food frequency questionnaire method; the correlation coefficients were 0.13 and 0.07, respectively. With the increasing of salt intakes by subjects' self-judgment, salt intakes were all rising significantly using three survey methods. Salt intakes of three group population of light, moderate and partial taste salty were 13.6, 13.6 and 14.7 g/d by 24 hours urinary Na method (F = 0.47, P < 0.05); 11.0, 12.0 and 12.7 g/d by food weighted record method (F = 5.83, P < 0.05), and 9.3, 10.2 and 11.9 g/d by food frequency questionnaire method (F = 5.83, P < 0.05), respectively.</p><p><b>CONCLUSION</b>Comparing with 24 hours urinary method, food weighted record method and food frequency questionnaire method would undervalue dietary salt intake. Salt intake status can be more accurately assessed by adjusting the underestimation rate.</p>
