RESUMEN
ObjectiveTo investigate effect of conducting training of autism spectrum disorder (ASD) early screening skill on improving the ability to early identify ASD of medical staffs in primary care hospitals. MethodsIn September 2021, the training of ASD early screening skills was carried out for medical staffs from 20 primary care hospitals in Chengdu. After training, the training effect was evaluated. The numbers of referrals from primary care hospitals to superior hospitals, confirmed ASD as well as their average diagnostic age of children with ASD before and after training were used as evaluation indicators. ResultsAfter training, the number of children with suspected ASD referred by primary care hospitals was more than that before training [(16.65±11.60) vs. (3.40±2.23), t=5.431, P<0.01], the number of children diagnosed with ASD was more than that before training[(6.85±4.93) vs. (2.45±1.67), t=4.171, P<0.01], and the differences were statistically significant. As for the diagnosed age of ASD children, after training, the average age was lower than that before training [(34.95±11.67) vs. (42.2±14.64), t=-2.553, P=0.019]. ConclusionTraining of ASD early screening skills for medical staffs in primary care hospitals may help to improve their ability to early screening ASD children.

Objective@#The main purpose of this study was to explore the health effects of occupational exposure to lead exceeded.@*Methods@#We collected 114 inpatients who exposure to lead, and diagnosed lead toxicity by No. 5 Suzhou People's Hospital from January 2011 to May 2018. Samples were selected according to 1:4 of the lead exceeded group and the control group. The age and gender of the lead exce eded group were matchied, and balanced between the two groups. Lead exceeded group: 84 inpatients occupational exposure to lead, whose blood or urinary lead exceeded. Control group: 336 healthy checkup persons who did not contact with any toxic or hazardous substances.@*Results@#The diastolic blood pressure of lead exceeded group was significantly higher than control group (P<0.05) . The red blood cell count, hemoglobin, mean red blood cell volume, mean hemoglobin content, mean hemoglobin concentration, the platelet count, and the lymphocyte count levels of lead exceeded group were significantly lower than control group (P<0.05) , while the average platelet volume level of lead exceeded group was significantly higher than control group (P<0.05) . The aspartate aminotransferase, glucose and the urea nitrogen levels of lead exceeded group were significantly higher than control group, while the creatinine of lead exceeded group was significantly lower than control group (P<0.05) . The total protein, albumin, cholesterol and low density lipoprotein levels of lead exceeded group were significantly lower than control group (P<0.05) . The abnormal rate of electrocardiogram and spleen B (24.4%, 8.33%) in lead exceeded group were significantly higher than control group (11.04%, 0.6%) (P<0.05) . The abnormal rate of liver B ultrasound, and gallbladder B ultrasound (23.81%、8.32%) in lead exceeded group were significantly lower than control group (41.32%、21.06%) (P<0.05) .@*Conclusion@#Occupational exposure to lead exceeded not only has a significant impact on red blood cell related indicators, but also has a certain impact on cardiac function and liver and kidney functions. It is suggested that lead exprsure may have some effect on health of occupational population.

Objective To investigate the correlations between plasma indoxyl sulfate and p-cresyl sulfate in the pathogenesis of cardiovascular complications in maintenance hemodialysispatients.Methods A total of 145 maintenance hemodialysis patients were selected.The researchers measured the physiological parameters of the subjects,including pre albumin,albumin,hemoglobin,blood urea nitrogen,creatinine,uric acid,calcium,phosphorus,alkaline phosphatase,total cholesterol,triglyceride,low-density lipoprotein cholesterol,high-density fat cholesterol,intact parathyroid hormone,C-reactive protein,apolipoprotein,lipoprotein,homocysteine,beta 2-microglobulin,sulfuric acid indoxyl,sulfuric acid cresol,serum iron,transferrin,ferritin,and N-terminal pro brain natriuretic peptide carrier.Subjects underwent cardiac ultrasound examination.Results The researchers used heart structure and function as the dependent variable.The single factor Cox regression analysis showed that the risk of heart structure and function changes increased with the increase of systolic blood pressure,N-terminal B-type natriuretic peptide,and left ventricular mass index.This study also showed that the risk of heart structure and function changes in patients with previous history of coronary heart disease also increased.The researchers took the systolic blood pressure,coronary heart disease history,N-terminal brain natriuretic peptide,and the left ventricular mass index as the dependent variables.Multifactor Cox regression analysis showed that the history of coronary heart disease,the high left ventricular mass index and the change of the heart structure and function of the patients with acute coronary heart disease were the independent predictors of the change of heart structure and function.The researchers used cardiovascular complications as the dependent variable.Cox regression analysis showed that,with the increase in patient's age,dialysis duration,elevated high C-reactive protein and sulfuric acid p-cresol,patients suffering from the risk of fatal cardiovascular complications rise.The researchers used the complications of cardiovascular deaths as dependent variable,age,duration of dialysis,C-reactive protein,and sulfuric acid p-cresol as covariates,multivariate Cox regression analysis of the results showed that with increasing age,dialysis duration increased,high sulfate of cresol and C-reactive protein,patients suffering from the risk of death from cardiovascular complications rise.Conclusions The history of coronary heart disease,left ventricular mass index,systolic blood pressure,indoxyl sulfate,Nterminal brain natriuretic peptide,age,dialysis age,high C-reaction protein,and p-cresol sulfate are the independent risk factors for cardiovascular complications.The relationship between indoxyl sulfate and sulfuric acid serum concentration of p-cresol and adverse cardiovascular events is most closely.
RESUMEN
Objective To determine whether pyloric measurements with ultrasound, that muscle thickness and channel of pyloric, correlated with weight and age in patients with hypertrophic pyloric stenosis (HPS). Methods A retrospective analysis was conducted on 111 cases diagnosed with HPS by operation from 2008 to 2012. Pearson correlation and linear regression analyses were used to determine if there were sta?tistically signiifcant associations between these combinations of factors:age and pyloric muscle thickness, weight and pyloric muscle thickness, age and pyloric length, and weight and pyloric length. Results Patients’mean age was 39.1 d (8-92 days). Their mean weight was 4.3 kg (2.2-7.9 kg). Mean pyloric muscle thickness was 4.8 mm (2-4.6 mm), and mean pyloric length was 17.5 mm (12-23.5 mm). Pearson correlation coefifcient analysis showed a signiifcant correlation between age and muscle thickness (r=0.6, P<0.001) as well as weight and muscle thickness (r=0.486, P<0.001). No signiifcant correlation was found be?tween pyloric length and age or weight. Linear regression analysis demonstrated similar results. Conclusions In patients with HPS, pyloric muscle thickness was directly related to age and weight. Smaller and younger infants with suspected diagnosis of HPS should be followed up even though the minimum diagnostic criterion for muscle thickness or length was not found on ultrasound.
