Background In the context of global warming, the impact of meteorological factors on human health has gradually become a research hotspot at home and abroad. Objective To describe the distribution of children's bronchopneumonia in Huzhou City, and explore the influence of diurnal temperature range (DTR) on children with bronchopneumonia, so as to provide guidance for identifying vulnerable populations and developing targeted measures. Methods A distributed lag nonlinear model (DLNM) was used to explore the potential nonlinear lag effect of DTR on admission of children with bronchopneumonia in Huzhou City from 2014 to 2019. Then a generalized additive model (GAM) was used to calculate the hospital admission risk of exposure to DTR in total population and sex-, age-, season-stratified populations. Results A total of 17658 hospitalized children with bronchopneumonia were included in the study. When DTR exceeded 7.5 ℃, the relative risk rose abruptly. When DTR reached 17 ℃, the risk of admission to hospital of children with bronchopneumonia was the greatest. In terms of the single-day lag effect, the admission risk of DTR for bronchopneumonia in children began on the same day and persisted until lag day 2; it peaked on the same day, and RR was 1.353 (95%CI: 1.220-1.502). The cumulative lag effect occurred from lag0 to lag0-6, and the highest RR value was at lag0-3, which was 1.938 (95%CI:1.483-2.533). The results of stratified analysis showed that the maximum effect values for boys and girls appeared at lag0-3 (RR_boys=2.301, 95%CI: 1.671-3.169) and lag0-2(RR_girls=1.566, 95%CI: 1.152-2.129) respectively, and the effect value and duration of DTR in boys were higher and longer than those in girls. Among different age groups, both children of 0-3 years old and 4-14 years old had the maximum effect value at lag 0-3, the RR values were 1.734 (95%CI: 1.454-2.572) and 1.998 (95%CI: 1.226-2.254) respectively, and the effect value and duration of DTR on the children of 4-14 years old were higher and longer than those of the children of 0-3 years old. As to seasons, no significant increase was found in cumulative effect in summer and autumn (P>0.05); in winter and spring, the maximum effect value appeared at lag0-10, and the RR value was 4.164 (95%CI:1.191-14.561). Conclusion The impact of DTR on bronchopneumonia in children is acute. Boys and children aged 4-14 years old are more sensitive to DTR changes. Therefore, we should be alert to severe DTR changes and take protective measures in advance

Objective:To explore the effect of exercise therapy on the exercise capacity and quality of life of maintenance hemodialysis patients.Methods:A total of 90 patients who underwent regular dialysis in Henan Provincial People′s Hospital, People′s Hospital of Zhengzhou University from April to December, 2020 were selected as the research objects by convienient sampling method. They were divided into experimental group and control group by random number table method, with 45 cases in each group. The control group was given routine nursing, and the experimental group took exercise therapy on the basis of routine nursing. The intervention lasted for 12 weeks. The changes in the exercise capacity and quality of life of the two groups before and after the intervention were observed.Results:Finally, 43 patients were included in the control group and 41 patients in the experimental group. There was no significant difference in the exercise capacity and quality of life before the intervention between the two groups( P>0.05). After the intervention, the maximum oxygen uptake, anaerobic threshold, 6MWT distance were (15.22 ± 3.08) ml·kg -1·min -1, (620.70 ± 53.56) ml·kg -1·min -1, (475.36 ± 50.51) m in the experimental group, and (12.22 ± 2.46) ml·kg -1·min -1, (590.18 ± 52.07) ml·kg -1·min -1, (444.50 ± 46.09) m in the control group, the differences were statistically significant between the two groups( t=3.32, 2.68, 296, all P<0.05). After the intervention, the scores of physiological function, physiological intelligence, physical pain, overall health, vitality, social function, emotional function and mental health dimensions of the quality of life were (84.32 ± 18.53), (84.61 ± 25.80), (76.40 ± 18.15), (59.02 ± 15.38), (52.22 ± 13.68), (69.56 ± 17.29), (94.24 ± 29.47), (73.44 ± 12.86) points in the experimental group, and (76.25 ± 17.35) (66.37 ± 27.63), (65.68 ± 17.54), (47.26 ± 15.45), (44.86 ± 13.14), (61.82 ± 16.51), (76.30 ± 26.14), (64.17 ± 13.36) points in the control group, the differences were statistically significant between the two groups( t values were 2.08-3.54, all P<0.05). Conclusions:Exercise therapy during dialysis can enhance exercise capacity and improve quality of life in maintenance hemodialysis patients.

Objective:To study the personality development of obsessive-compulsive disorder (OCD) from the perspective of memory-tracing.Methods:From January 2016 to May 2017, totally 103 patients with OCD (patient group) and 88 normal subjects (control group) matched with age, gender, and educational level in the national urban population norm database of Wang Weidong memory-tracing personality developmental inventory (WMPI) were included.WMPI was used to evaluate and compare all subjects.SPSS 22.0 software and nonparametric test were used for statistically analysis, and independent sample t-test and nonparametric test were used for data camparison. Results:1.In terms of external influencing factors of personality development: on the part of life events, the score of family affair in the patient group was higher than that in the control group( P<0.05) in childhood.In terms of upbringing, the scores of strictness (5.637±3.463) and punishment (6.275±4.565) in the patient group were higher than those ((4.341±3.092), (5.000±3.698)) in the control group in childhood( t=-2.703, -2.093, both P<0.05). 2.In the aspect of personality elements: (1) Among courage subscales, the scores of natural fear (7.686±3.441) and adaptability (15.000±5.321) in the patient group were higher than those((6.023±3.991), (12.841±6.070)) in the control group in childhood ( t=-3.085, -2.613, both P<0.05) .For all three stages, interpersonal fear scores in the patient group ((20.284±8.255), (22.804±7.458), (22.725±7.145))were all higher than those ((16.205±7.937), (19.841±6.319), (18.364±6.277))in the control group( t=-3.458, -2.929, -4.437, P<0.01). (2) Among interpersonal relationship, the dependence dimension scores were higher in the patient group (10.804±3.621) than those (8.830±4.850) in the control group during childhood( t=-3.205, P<0.01). (3) Among sex development, the scores of heterosexual communications (11.941±4.878), love concept (15.098±4.180) and sexual concept (8.892±2.988) were higher in the patient group than those ((9.125±5.040), (11.761±5.202), (6.943±3.288)) in the control group in adolescence(all P<0.01). (4) Among ego, the score of self-care dimension in the patient group (6.465±2.890) was higher than that in the control group(4.239±2.861) in childhood ( P<0.01). In the dimension of autonomy, the scores of the patient group ((10.772±2.694), (11.347±2.621)) were higher than those in the control group ((8.011±4.039), (9.818±2.693)) in childhood and adolescence (both P<0.01). (5) Among the way of thinking, the score of absolute thinking dimension in the patient group was higher than that in control group in childhood ( P<0.01). In the dimension of cautious, the scores of patient group were higher than those in the control group in childhood and adolescence (both P<0.01). (6)Among volition, the scores of decisive dimension in the patient group were higher than those in the control group in adolescence and youth (both P<0.01). In the dimension of consciousness, the score of patient group was higher than that in the control group in youth( P<0.01). In the dimension of insistence, the score of the patient group were higher than those in the control group in childhood and youth (both P<0.01). (7) Among worldviews, the scores of motivations, perspective of career and perspective of friendship in the patient group were higher than those in the control group in adolescence (all P<0.01). The score of value dimension in patient group was lower than that in the control group in the youth ( P<0.01). Conclusion:Patients with OCD have more strictness and punishment during their childhood in terms of upbringing.This leads to a lack of courage, poor interpersonal relationships, low self-care or autonomy, high attachment, absolutization of thinking and suppressing themself more in their childhood.In their adolescence and youth, their lack of courage, poor self-care or autonomy and the way of thinking cautious and stubborn will further aggravate and gradually show a more conservative sexual development and traditional world outlook.

【Objective】 To evaluate the diagnostic value of prostate specific antigen density (PSAD) and central glandular prostate specific antigen density (CGPSAD) combined with multi-parameter magnetic resonance imaging (mpMRI) in the diagnosis of prostate cancer (PCa) and prostate hyperplasia (BPH) in the gray area of prostate specific antigen (PSA) (4.0-10.0 μg/L). 【Methods】 Data of 634 patients who had received prostate biopsy in our hospital were retrospectively collected. Among them, 121 patients were selected. According to the pathological results of the biopsy, they were divided into PCa group and BPH group. The three diameters of the prostate and the central gland were measured by MRI. We calculated the prostate volume (PV) and the central gland volume (PVc), and then compared age, PSA, PV, PVc, PSAD, CGPSAD, prostate images, and PI-RADS score between PCa and BPH groups. Multifactor logistic regression analysis was performed to study the independent risk factors for PCa. Receiver operating characteristic (ROC) curves of PCa diagnosis were plotted, respectively, and the area under the curve (AUC) was calculated and compared with the reference. 【Results】 There was no significant difference in total prostate specific antigen (tPSA) between the two groups (P>0.05). However, significant differences were observed in age, PV, PVc, PSAD, CGPSAD and PI-RADS score between the two groups (P<0.05). Multifactor logistic regression analysis showed that PI-RADS score was an independent risk factors for PCa (OR=4.156, P<0.001). The AUC value of PSAD, CGPSAD, PI-RADS score, PSAD combined with PI-RADS score and CGPSAD combined with PI-RADS score were 0.744, 0.771, 0.844, 0.884, and 0.903, respectively. The AUC value of CGPSAD combined PI-RADS score was the highest. 【Conclusion】 CGPSAD is better than PSAD in diagnosing PCa in the grey area of PSA. Combined with PI-RADS score of mpMRI, it can improve the diagnosis of prostate cancer and guide clinical and prostate biopsy.
