Objective To study the Hainan Utstein templates used for cardiac arrest and resuscitation registries to evaluate the epidemiological characteristics and outcomes of the patients with CPR by multi-center study. Methodsccording to the Utstein templates for cardiac arrest and CPR set by International Liaison Committee on resuscitation in 2004, a Hainan Utstein CPR registry chart was designed and a prospective descriptive study was carried out to evaluate the epidemiological characteristics, impact factors and outcomes of the patients with resuscitation attempt in emergency departments of thirteen hospitals in Hainan Island between January 2007 and December 2010.Results Of 1125 patients with cardiac arrest, male accounted for 73. 8% and female was 26. 2%. The mean ( ± S. D) age of the cardiac arrest patients was 53.9 ± 13. 1 years old.Coronary heart diseases and hypertension were the most common preexisting chronic diseases in the studied patients. The ROSC rate and discharge rates after survival in 1125 patients with CPR were 23. 8% and 7.4% respectively. The ROSC rate and discharge rates after survival were 36. 3% and 11.6% in the in-hospital cardiac arrest (IHCA) group, respectively whereas 11.5% and 3. 3% in out-hospital cardiac arrest (OHCA) group. Of 188 patients with ventricular fibrillation/Pulseless ventricular tachycardia, the ROSC rate and discharge rate after survival were 58.0%and 21.8%,respectively. Of them, 448 (39. 8% ) of the cardiac arrest patients had underlying cardiac causes, and the ROSC rate and discharge rate after survival were 36. 3% and 11.5% respectively in IHCA group whereas 11.6% and 3. 3% in OHCA group. The ROSC rate and discharge rate after survival were 69. 8% and 7. 4%respectively in the tertiary hospitals whereas 30. 2% and 7. 3% in the secondary hospitals. Conclusions Patients experienced cardiac arrest were predominantly male. Coronary heart disease and hypertension were the two most common preexisting chronic diseases. The ROSC rate and discharge rate of patients with IHCA were higher than those with OHCA. ROSC rate and discharge rate after survival were higher in the ventriculat fibrillation/Pulseless ventricular tachycardia group than the other cardiac rhythms first witnessed groups. The time delayed of starting CPR after onset of cardiac arrest had a critical impact on survival and discharge rate in both IHCA and OHCA groups.

Methods A total of 608 and 622 RHTSIs with radiation health technical service qualifications from 31 provinces, autonomous regions, and municipalities in the years of 2021 and 2022 were selected as the research subjects. The data of quality monitoring of radiological health technology services, comparison of radiological health testing capabilities, and investigation of the current status of technical support institutions were collected to analyze the status of technical service items which was conducted by RHTSIs from 2021 to 2022. Results A total of 622 RHTSIs in China obtained technical service institution qualifications in 2022, an increase of 14 from 608 in 2021. While a total of 404 of 622 RHTSIs conducted radiological health technology services, a decrease of 11.4% from 456 in 2021. A total of 241 804 technical service items were conducted in 2022, an increase of 39.7% from 173 064 in 2021. The median number of technical service items by non-health system RHTSIs was higher than that of the health system RHTSIs in 2021 and 2022, (203 vs 40 items, 215 vs 55 items, all P<0.01). The number of technical service institutions and technical service items conducted in different regions from high to low were the eastern, central, and western regions in 2021. The number of technical service institutions in different regions was highest in the eastern region, followed by the central and western regions, while the number of technical service items from high to low were the eastern, western, and central regions in 2022. The number of provincial, municipal, and county-level health system RHTSIs decreased by 6.5%, 26.3%, and 27.3%, respectively, in 2022 compared with 2021. The number of technical service items conducted by provincial health system RHTSIs increased by 48.6%, while those conducted by municipal and county-level health system RHTSIs decreased by 13.8% and 21.3%, respectively. Conclusion Although the number of RHTSI conducting technical services decreases in 2022 compared with 2021, the number of technical service items conducted increases. Non-medical RHTSI undertake the majority of technical service items. Within the medical institutes, the number of technical service items conducted by provincial RHTSI is higher than that of municipal and county-level RHTSI.

OBJECTIVETo evaluate the association between chemical exposure, DNA methylation status and gene-environment interactions in the development of childhood acute leukemia (AL).
METHODSFrom January 1st 2009 to December 31st 2010, an exploratory case-control study was conducted on childhood AL among children who were less than 15 years of age in Shanghai, China. A total of 131 patients with newly diagnosed AL were recruited from 3 Shanghai children hospitals. The controls selected from the same hospital were healthy children who attended the physical check-up held by the department of Children's Healthcare, or who visited the clinic of developmental pediatrics or orthopedics (excluding blood diseases and malignant tumors). 140 controls matched with cases in gender and age were included in this study. Chemical exposure were investigated by questionnaires, methylation specific polymerase chain reaction (MSP) was adopted to analyze the methylation or deletion status of 8 genes, and gene-environment interactions were analyzed by relative excess risk of interaction (RERI), attributable proportion of interaction (API) and synergy index (S).
RESULTSThere were 131 and 140 subjects in case and control group, who were aged (6.9 ± 3.8) and (6.9 ± 3.9) years old (t = 0.01, P = 0.911), respectively. After adjusting age and other potential confounding factors, chemical substances' exposure of children/mother/father were all significantly higher in cases than that in controls (Children: OR = 3.90, 95% CI: 1.69-9.02; Mother: OR = 2.71, 95% CI: 1.12-6.52; Father: OR = 1.91, 95% CI: 1.05-3.47). For the 8 genes analyzed, the methylation status of DAPK and PTEN and P73 in case group were significantly higher than that in control group (cases: 3.1% (4 cases), 16.0% (21 cases), 7.6% (10 cases); controls: 0.7% (1 case), 2.9% (4 cases), 0.7% (1 case); χ²: 7.11, 16.90, 11.38; P value: 0.029, 0.000, 0.003). The methylation status of P16 in case group was significantly lower than that in control group (cases: 3.8% (5 cases); controls: 8.6% (12 cases), χ² = 10.33, P = 0.007). The interactions of children chemical substances' exposure and 3 genes' (PTEN, P16 and P73) methylation status were probably existed after adjusted for confounding factors (PTEN: RERI = -7.01, API = -2.14, S = 0.24; P16: RERI = 4.08, API = 0.53, S = 2.59; P73: RERI = 4.32, API = 0.48, S = 2.19), we also found the potential interaction between maternal chemical substances' exposure and PTEN, P16 gene methylation status (PTEN: RERI = -1.30, API = -0.38, S = 0.65; P16: RERI = 1.70, API = 0.38, S = 1.97).
CONCLUSIONThe study suggested the strong combined effects of chemical substances exposure of children and abnormal methylation status were risk factors of childhood AL, and there existed different interaction between them, which may indicate the important role in the pathogenesis process of childhood AL.

OBJECTIVETo investigate the association between children's and their parents' lifestyles, household environmental exposures and risk of childhood acute leukemia (AL).
METHODSA 1:2 matched case-control study of childhood AL was conducted in Shanghai between April 2011 and January 2014. The study enrolled 66 cases aged < 15, diagnosed with AL and 132 controls matched by age, gender and residence. All of the controls had no hematological diseases or previous history of malignancy. Children who had been adopted and had congenital genetic syndromes such as Down's syndrome or a positive HIV test result were not eligible as either cases or controls. Information was obtained from standardized face-to-face interviews of their parents/guardians with detailed questions on demographic characteristics, lifestyle, and household environment. Conditional logistic regression models were used to analyze effecting factors of childhood AL, odds ratios (OR) and their 95% confidence intervals (CI) were calculated.
RESULTSAmong 198 cases, 66 cases were aged (5.0 ± 3.7) years old, and 132 controls were aged (6.0 ± 3.8) years old (t = 0.48, P = 0.523). The paternal drink frequencies of cases and controls were 57.6% (38/66), and 31.1% (41/132), respectively (χ² = 4.91, P = 0.027). And the frequencies of household insecticides usage in the last year in the two groups were 78.8% (52/66), and 65.2% (86/132) (χ² = 3.87, P = 0.049). Chemical exposure during childhood (OR = 4.76, 95% CI: 1.34-16.89), maternal exposure to chemicals (OR = 4.51, 95% CI: 1.65-12.33), household insecticides use during 0-3 years of child (OR = 2.90, 95% CI: 1.31-6.39), and renovating after their children's birth (OR = 3.12, 95% CI: 1.26-7.74) were associated with an increased risk of childhood AL and these differences between the cases and the controls have statistical significance. Besides, we found that frequent contaction with other children during 0-3 years old (OR = 0.32, 95% CI: 0.15-0.69) and ventilation during sleeping in summer (OR = 0.43, 95% CI: 0.18-0.98) were associated with a decreased risk of childhood AL.
CONCLUSIONOur results support the association between children's and their parents' lifestyles, household environmental exposures and childhood AL.
