Objective:To explore the effects of staged thematic painting therapy on positive emotions, alexithymia and self-efficacy in children with emotional disorders.Methods:This was a quasi-experimental study. By convenient sampling, 61 children with emotional disorders admitted from January 2022 to December 2022 to the Department of Child and Adolescent Psychology, Affiliated Psychological Hospital of Anhui Medical University were selected as the research objects, 31 patients admitted from January 2022 to June 2022 were listed as the control group and 30 patients admitted from July 2022 to December 2022 were listed as the observation group according to the time of admission.The control group was given routine psychiatric care, and the observation group was given staged thematic painting therapy on this basis. The intervention time was 6 weeks. The intervention effect was evaluated by Positive and Negative Affect Scale,Toronto Alexithymia Scale, and General Self-Efficacy Scale.Results:There were 15 males and 16 females in the control group, aged (14.19 ± 1.79) years old. There were 13 males and 17 females in the observation group, aged (14.47 ± 1.55) years old. The difference in baseline data between the two groups was not statistically significant ( P>0.05) and was comparable. There was no significant difference in the score of positive emotions, alexithymia and self-efficacy before intervention between the two groups (all P>0.05). After intervention, the scores of positive emotions and self-efficacy in the observation group were (43.20±7.41), (31.88 ± 5.42) points, which were higher than those in the control group (33.81 ± 6.92), (21.24 ± 5.41) points, the differences were statistically significant ( t=-6.19, -5.63, both P<0.05). After intervention, the scores of alexithymia in the observation group was (53.44 ± 4.68) points, which was lower than that in the control group (60.44 ± 5.52) points, the difference was statistically significant ( t=-8.72, P<0.05). Conclusions:Staged thematic painting therapy can effectively improve the positive emotions, self-efficacy and alexithymia level of children with emotional disorders, help the patients establish confidence to overcome the disease. It is valuable in clinical practice.

Objective:To investigate the correlation between the variability of blood uric acid level and the progression of type 2 diabetic nephropathy and retinopathy.Methods:A total of 240 patients with type 2 diabetic nephropathy were selected from a cohort established in Pinggu District Hospital of Beijing in 2015 for retrospective analysis. The blood uric acid level of the patients was measured, the variability of uric acid level was calculated, and the patients were divided into group A, group B, group C and group D according to the quartile of uric acid variability, with 60 cases in each group. The subjects were followed up, and their general information, biochemical indicators, diabetic nephropathy and diabetic retinopathy were collected. According to the diabetic nephropathy and retinopathy during follow-up, the subjects were divided into progressive group and non-progressive group, so as to further clarify the correlation between the variability of blood uric acid level and the progression of diabetic nephropathy and retinopathy.Results:Up to the last follow-up date in July 2022, a total of 24 cases were lost to follow-up in group A, 27 cases in group B, 20 cases in group C, and 22 cases in group D. Finally, 36 cases were included in group A, 33 cases in group B, 40 cases in group C, and 38 cases in group D. There was no significant difference in age, gender, body mass index, systolic blood pressure, diastolic blood pressure, cholesterol, triglyceride, low density lipoprotein cholesterol, fasting blood glucose, glycated hemoglobin and serum creatinine among four groups ( P>0.05). Univariate analysis showed that the incidence of diabetic nephropathy and retinopathy progression increased with the increase of the quartile of uric acid variability in patients with type 2 diabetes (the incidences of progression in A, B, C and D groups were 16%, 49%, 63% and 79%, F = 0.95, P<0.05). Pearson correlation analysis showed that blood uric acid variability was positively correlated with the progression of diabetic nephropathy and retinopathy ( r = 0.482 and 0.501, P<0.05). Logistics regression analysis showed that with the increase of the quartile of uric acid variability, the progression risk of diabetic nephropathy ( OR = 3.521, 5.226 and 6.548; P<0.05) and retinopathy ( OR = 3.733, 4.844 and 5.872; P<0.05) in type 2 diabetes patients increased gradually. Conclusions:The variability of blood uric acid level is positively correlated with the progression of type 2 diabetic nephropathy and retinopathy. The higher the risk of progression of diabetic nephropathy and retinopathy with the increase of quartile of blood uric acid level variability, the more important it is to regularly monitor the blood uric acid level of type 2 diabetic patients.

Objective To evaluate the clinical screening value of the Epworth sleepiness scale(ESS)for patients with type 2 diabetes mellitus(T2DM)and obstructive sleep apnea hypopnea syndrome(OSAHS).Methods A total of 399 hospitalized T2DM patients were selected for portable monitoring(PM)and ESS assessment.Based on the presence or absence of OSAHS,the study was divided into a simple T2DM group(T2DM,n=143)and a group with comorbid OSAHS(OSAHS,n=256).According to the apnea-hypopnea index(AHI),the study participants were categorized into a normal group(AHI<5 times/h,n=143),a mild OSAHS group(AHI 5～15 times/h,n=147),a moderate OSAHS group(AHI>15～30 times/h,n=69),and a severe OSAHS group(AHI>30 times/h,n=40).Differences in ESS scores across various OSAHS severity groups were compared.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate the screening value of ESS for OSAHS.Results Body mass index,proportion of obesity,proportion of central obesity,serum creatinine and fasting C-peptide were significantly higher the OSAHS group compared to the non-OSAHS group(P<0.05).Significant statistical differences in ESS scores were observed between the severe and mild OSAHS groups(P=0.006).When an ESS score of≥9 was used as the threshold for screening OSAHS,the concordance rate with PM diagnosis was 40.6%.ROC curve analysis revealed that the area under the curve(AUC)for ESS screening for OSAHS,moderate-to-severe OSAHS,and severe OSAHS,and their respective optimal thresholds(95%CI),were as follows 0.518(95%CI 0.459～0.577,P=0.545),0.571(95%CI 0.507～0.635,P=0.029)and 0.624(95%CI 0.531～0.718,P=0.010),with cutoffs of≥2 points,≥3 points,and≥4 points,respectively.Conclusions An increased ESS score in T2DM patients significantly indicates the likelihood of severe OSAHS.Using an ESS score of≥9 as a threshold to screen for OSAHS is ineffective,whereas an ESS score of≥3 for screening moderate-to-severe OSAHS and≥4 for severe OSAHS has some reference value.

Objective:To evaluate the effect of ionizing radiation on chromosome aberration of peripheral blood lymphocytes in children with vascular interventional procedure.Methods:The chromosome aberration of peripheral blood lymphocytes was analyzed before and after vascular interventional procedure to assess the effect of low-dose ionizing radiation on chromosomes. Peripheral blood (PB) was collected using heparin as an anticoagulant from 26 patients before and after (within 10 minutes) vascular interventional surgery. Informed consent was obtained from the patients′ parents.Results:Dicentric + centric ring (dic+ r) formation increased significantly ( U=647, P<0.01) in peripheral blood lymphocytes of children after interventional operation. No correlation was observed between the rate of dic+ r and the cumulative dose (CD), dose area product (DAP), age, body weight, gender and the estimated effective dose E ( P>0.05). There was no significant difference in dic+ r rate of children between different genders, ages and lesion sites ( P>0.05). The dic+ r rate after interventional operation exceeded 40×10 -3 in 4 of 26 cases with the highest of 95.83×10 -3. Conclusions:The ionizing radiation during children′s vascular interventional procedure might lead to the increase of chromosome aberration of peripheral blood lymphocytes and some children are abnormally sensitive. Great attention should be paid to the justification and radiation protection during interventional procedure for children.

Objective To explore the relationship and influencing factors between pre‐diabetes mellitus (pre‐DM) and hypertension, providing evidence for formulating strategies for cardiovascular disease prevention and control. Methods We conducted this study from June 2013 to September 2014. Using stratified multistage random sampling, participants were administered a questionnaire survey, their height, weight, waist circumference, hip circumference, other physical attributes, blood pressure and blood lipids were measured. They also underwent the 75‐g glucose tolerance test and other laboratory examinations. A logistic regression model was used to analyze the relationship between pre‐DM and hypertension and its influencing factors. Results A total of 4 002 participants completed the survey. Participants'mean age was 50.3 ± 11.8 years. Of the total participants, 1 962 (49.0%) were males, while 2 039 (51.0%) were females; 1 participant had missing gender data. Further, 2 188 participants had normal glucose metabolism, 1 066 had pre‐DM, and 748 had diabetes. The prevalence of hypertension in participants with normal glucose metabolism, impaired fasting glucose, impaired glucose tolerance, both impaired fasting glucose and impaired glucose tolerance, and DM was 28.3%, 46.5%, 46.3%, 62.0%, and 61.2%, respectively. The prevalence of hypertension varied among people with different glucose metabolism (χ2=306.672, P<0.001). The prevalence of hypertension in the pre‐DM population increased with the aggravation of abnormal glucose metabolism compared to the normal glucose metabolism population, with a linear trend (χ2=299.009, P<0.001). Among those with abnormal glucose metabolism, there were differences in age, cholesterol, triglycerides, low‐density lipoproteins, body mass index, and waist circumference compared to those without hypertension (P<0.05). The risk of hypertension in the pre‐diabetic population was 1.5 times higher than that in the normal glucose metabolism population (OR=2.510, 95% CI: 2.156-2.922, P<0.001). There was no difference in the correlation intensity between pre‐DM and hypertension when gender was taken into account. Age and lipid abnormalities slightly decreased the correlation intensity between abnormal glucose metabolism and hypertension. Considering body mass index and centripetal obesity, the correlation intensity between abnormal glucose metabolism and hypertension could be reduced by controlling these factors. Conclusion The prevalence of hypertension is high in people with pre‐DM. There is a correlation between pre‐DM and hypertension, even when considering factors such as age, dyslipidemia, body mass index, and centripetal obesity. Therefore, it is necessary to strengthen the management of blood pressure in the pre‐diabetic population; improve early intervention for risk factors such as dyslipidemia, body mass index, and centripetal obesity; and reduce the occurrence of hypertension.

Hematopoietic stem cell ( HSCs) injury induced by ionizing radiation ( IR) is the primary cause of death after exposure to ionizing radiation .The mechanisms of inducing HSCs damage include induction of HSCs apoptosis via the P53-Puma pathway;promotion of HSCs differentiation via the activation of the G-CSF/Stat3/BATF-depend-ent differentiation checkpoint;induction of HSCs senescence via the ROS-P38 pathway; and damage to the HSCs niche.Recent researches provide a basis for the prevention and treatment of bone marrow suppression caused by ionizing radiation .
