Objective To investigate the correlation between food intolerance and Henoch-Sch(o)nlein purpura (HSP) in children and the efficacy of food forbidden or alternative therapy. Methods The levels of IgG against several common food in serum obtained from 40 children with HSP were measured by ELISA. The efficacy of food forbidden or alternative food therapy was assessed after 3 months. Results Total positive rate of serum food-intolerant IgG antibodies in HSP children was 92.5%. Among these 14 intolerant foods, the positive percentage of egg was the highest (33.8%), followed by tomato (14.9%), milk (13.5%) and morrhua (12.2%). Significant differences of the sort and degree of food intolerance existed among different age groups (t=2.257, P=0.045), but not between boys and girls (t=1.053, P=0.315), city and countryside (t= 1.388, P=0.193). There was no linear correlation between total food intolerance and serum IgG level (t=0.793, P=0.445). Food intolerance had no direct relation to immune complex deposition in kidneys of HSP nephritis (r =-0.262, P =0.387). The efficacy of adjusting diet was 95% . Conclusions HSP is closely related to food intolerance. Egg is the most common intolerant food. Food forbidden or alternative therapy shows acceptable efficacy in the treatment of most Henoch-Sch(o)nlein purpura children.

Recently, some global cases of 2019 novel coronavirus (COVID-19) pneumonia have been caused by second- or third-generationtransmission of the viral infection, resulting in no traceable epidemiological history. Owing to the complications of COVID-19pneumonia, the first symptom and imaging features of patients can be very atypical and early diagnosis of COVID-19 infectionsremains a challenge. It would aid radiologists and clinicians to be aware of the early atypical symptom and imaging featuresof the disease and contribute to the prevention of infected patients being missed.

Objective:To compare the effect of different methods of sputum aspiration in children with bronchopneumonia and explore the appropriate sputum aspiration methods for children with bronchopneumonia.Methods:This study was a randomized controlled trial. The convenience sampling method was used to select 165 children with bronchopneumonia treated in the Third Affiliated Hospital of Zhengzhou University from October 8, 2020 to September 30, 2021 as the research objects. They were divided into group A, group B and group C by random number table method, with 55 cases in each group. Group A used sputum aspirating tube to aspirate sputum through mouth and nose, group B used olive head to aspirate sputum through nose, and group C used both sputum aspirating tube to aspirate sputum through mouth and olive head through nose. The sputum aspirating effect, respiratory mucosal injury rate and satisfaction degree of children′s parents were compared among the three groups.Results:Finally, there were 53 cases in group A, 54 cases in group B and 53 cases in group C. The total effective rate of sputum aspiration was 96.21%(584/607) in group C, which was higher than that in group A 94.32% (581/616) and in group B 74.12% (464/626), the difference was statistically significant ( χ2=194.62, P<0.01), pairwise comparison among the three groups showed statistical difference ( χ2=95.95, 11.32, 132.16, all P<0.017). The respiratory mucosal injury rate was 1.12% (7/626) in group B, which was lower than that in group C 3.13% (19/607) and in group A 10.39% (64/616), the difference was statistically significant ( χ2=63.53, P<0.01), pairwise comparison among the three groups showed statistical difference ( χ2=49.52, 25.47, 6.04, all P<0.017). The satisfaction degree of children′s parents in group C was 98.11% (52/53), which was higher than that in group B 90.74% (49/54) and in group A 81.13% (43/53), the difference was statistically significant ( χ2=8.54, P<0.05). There was no statistically significant difference in the satisfaction degree of children′s parents between group A and group B, and between group B and group C( P>0.017). There was statistically significant difference in the satisfaction degree of children′s parents between group A and group C ( χ2=8.22, P<0.017). Conclusions:The combination of oral suction tube and nasal suction with olive head can improve the sputum aspirating effect of children with bronchopneumonia and the satisfaction degree of their parents, with a low rate of respiratory mucosal injury and high safety, which is worthy of clinical reference.

Objective:To explore the application effects of the Doctor-nurse-therapist integrated Model on the patients with brain injury in the rehabilitation period.Methods:A total of 60 patients with brain injury from January 2016 to October 2017 were selected as the control group underwent interventions based on traditional treatment model involving medical treatment, nursing and rehabilitation, and then 56 patients with brain injury from January 2018 to October 2019 were aselected as the experimental group followed Doctor-Nurse-Therapist integrated model for rehabilitation treatment. All subjects were recruited from inpatients hospitalized in the Forth Department of Neurological Rehabilitation, Shanghai Yangzhi Rehabilitation Hospital (Shanghai Sunshine Rehabilitation Center). The differences of motor function, activities of daily life (ADLs), anxiety and depression scores between the two groups were compared.Results:After 6 weeks of interventions, the scores of motor function were 80.27±18.20 and 67.32±19.71, and ADLs scores were 73.14±19.18 and 64.59±20.33 for the experimental group and the control group, respectively. The differences of the motor function and ADLs scores showed statistical significance between the experimental group and the control group ( t values were 3.491, 2.105, P<0.05). The anxiety and depression scores were 44.68±12.29 and 42.61±17.95 in the experimental group, while 52.25±12.95 and 50.84±18.14 in the control group, respectively. Statistical significance was found according to differences of anxiety and depression scores between the experimental group and the control group ( t values were 2.965,-2.236, P<0.05). Conclusions:Under the integrated model, doctors, nurses and therapists can evaluate, discuss, formulate and implement the flow scheme of the model, which can significantly improve the motor function and daily life ability of patients with brain injury in the rehabilitation period as well as anxiety, depression and the quality of medical services, and reduce the burden of family and society.

Objective:To investigate the effect of hospital-community-family transitional rehabilitation care model on patients with brain trauma and explore an economic, effective, all-sided rehabilitation approach.Methods:A total of 82 in-patients with brain trauma were recruited from January 2018 to June 2019 in Shanghai Yang Zhi Rehabilitation Hospital (Shanghai Sunshine Rehabilitation Center). The participants were allocated into 2 groups based on randomized digital tables. Forty patients in the observation group received the hospital-community-family transitional rehabilitation care, and forty-two patients in the control group received routine rehabilitation care. All the participants completed assessments with the Fugl-Meyer Assessment Scale (FMA), the Barthel Index for the Activities of Daily Living (BI) and the Hamilton Anxiety Scale (HAMA) before the intervention, at discharge, 1 month, 4 months, 6 months and 10 months after discharge, respectively.Results:Before the intervention, no statistical significance was identified in the total scores of FMA, BI and HAMA between the two groups ( P>0.05). Compared to the control group, the total scores of FMA, BI and HAMA in the observation group were significantly improved at the discharge, 1 month, 4 months, 6 months and 10 months after discharge, respectively ( t values were -13.82 - 10.28, all P<0.05). Significant differences were observed in the level of FMA, BI and HAMA between the two groups across 6 time points ( Ftime×group=20.34, 18.34, 19.55, Ftime=183.24, 184.30, 179.09, Fgroup=28.86, 32.19, 26.63, all P<0.05). Conclusions:The hospital-community-family transitional rehabilitation care model which is based on medical consortium effectively improved traumatic brain-injured patients′motor function, the level of activities of daily living, and patients′anxiety. In addition, the model also improved the quality of medical services.

In China and abroad, Traditional Chinese Medicine (TCM) have been applied and developed. That is depended on doctors and scholars of the past dynasties to inseparable from the inheritance, protection, development, and innovation of Traditional Knowledge of Chinese Medicine. With the progress of modern society and people's awareness of traditional culture protection, people are also improving the understanding of TCM. Through the analysis of the situation and significance of the protection of Traditional Knowledge of Chinese Medicine and the development of Japanese Kampo medicines, recognized that the development of Kampo medicines ignored the source. Their original intention and purpose of protection the Traditional Knowledge of Medicine are completely different from China. The protection of Traditional Knowledge of Chinese Medicine should be in accordance with the basic national conditions, and the system of the protection of Traditional Knowledge of Chinese Medicine should be formulated and perfected to ensure the sustainable development of TCM.

Objective:To explore the promoted role of calcium-sensing receptor (CaSR) overexpression in proliferation and differentiation of immature white matter progenitor cells after ischemia in vitro. Methods:Periventricular white matter cells from 5-d-old rats were cultured in vitro and divided into control group, oxygen-glucose deprivation (OGD) group, OGD+gadolinium chloride (GdCl 3) group, and OGD+ CaSR silenced group. CaSR expression was agitated by GdCl 3, and CaSR gene expression was inhibited by gene silencing. CaSR mRNA levels 24, 48 and 72 h, and 7 and 14 d after OGD were detected by real-time fluorescence quantification-PCR (RT-qPCR); cell proliferation 48 h after OGD was detected by inverted microscope, and cell differentiation 24, 48, and 72 h, and 7 and 14 d was detected by double immunofluorescence staining. Results:(1) CaSR mRNA expressions: CaSR mRNA expressions in OGD group 48 and 72 h and 7 d after OGD were statistically higher than those in control group ( P<0.05). Forty-eight and 72 h, and 7 and 14 d after OGD, CaSR mRNA expressions in OGD+GDCL 3 group were statistically higher than those in control group and OGD group ( P<0.05); the CaSR mRNA expressions in the OGD+CaSR silenced group were significantly lower than those in the control group ( P<0.05). (2) Cell proliferation and differentiation: 48 h after OGD, the cell sphere diameter of OGD group ([75.26±26.07] μm) was significantly increased as compared with that of control group ([57.96±18.92] μm, P<0.05); the cell sphere diameter of OGD+GdCl 3 group ([91.92±21.82] μm) was significantly increased as compared with that of control group and OGD group ( P<0.05); and the cell sphere diameter of OGD+ CaSR silenced group ([24.09±8.34] μm) was significantly shorter than that of control group and OGD group ( P<0.05). At 48 and 72 h after OGD, the number of O4 +/CaSR + olidoendrocyte precursor cells (OPCs) in OGD group was significantly larger than that in control group, that in OGD+GdCl 3 group was significantly larger than that in control group and OGD group, and that in OGD+ CaSR silenced group was significantly smaller than that in control group and OGD group ( P<0.05). Conclusion:CaSR overexpression could promote the proliferation and differentiation of progenitor cells to OPCs.

Objective:To explore the correlation between the index of hemodynamics in perinatal period and retinopathy of prematurity(ROP), so as to provide basis for the better prevention and treatment of ROP.Methods:From May 2017 to April 2019, the preterm infants were admitted to the Neonatal Intensive Care Unit of the First Affiliated Hospital of Zhengzhou University at birth and were hospitalized for more than 2 weeks, gestational age ≤ 35 weeks and birth weight ≤ 2 500 g. They were selected as the study objects.The perinatal data including heart rate, blood pressure, patent ductus arteriosus, ventricular septal defect, and NT-proBNP level on the 1 st, 7 th and 14 th day, respectively after birth were collected.They were divided into ROP group and non ROP group according to the results of the retinopathy screening report.The influencing factors of ROP were screened out by univariate analysis and multivariate regression analysis. Results:A total of 1 119 subjects were included, 105 infants with ROP were detected, and the prevalence of ROP was 9.4%.Among them, 12 cases of pre-threshold lesion type 1 and threshold lesions required treatment, accoun-ting for 1.07% of screened preterm infants .Univariate analysis and multivariate regression analysis revealed that gestational age, birth weight, total oxygen therapy time, and intrauterine growth restriction were all factors affecting ROP, and 2 hemodynamic related indicators, such as the level of NT-proBNP in plasma on the 14 th day after birth, and placenta previa or abruption were also related to ROP( OR=0.604, 0.647, 1.276, 2.361, 1.688 and 2.506, respectively, all P<0.05). Conclusion:The hemodynamic changes in perinatal period may be involved in the formation of ROP, and it is necessary to further clarify its mechanism.

【Objective】 To investigate the status quo and existing problems of quality control laboratory of blood stations in Hebei province, and to provide reference for the capacity building of quality control laboratory in the future. 【Methods】 The data of routine blood collection and supply, blood component preparation, blood sampling ratio/frequency, and sampling results among 12 blood stations in Hebei in 2020 were collected. The monitoring effect of blood component quality in Hebei province, combined with the indicator changes of main blood components, were analyzed. 【Results】 Blood component preparation from blood stations in Hebei are different. The requirements for the number and frequency of routine sampling in each apartment are not standardized, and retrospective analysis was not conducted basically. Although the frequency and sampling of blood component quality monitoring can meet the minimum requirements of the Quality Monitoring Guidelines of Whole Blood and Blood Components 2017 and Technical Operating Regulations of Blood Stations (2019 Edition), but does not match the actual collection and preparation units. The qualification rate and reliability are unstable due to the small sample size. Monthly quality inspection can result in judgment errors, which is not conducive to systematic analysis and continuous improvement of blood collection and supply process. 【Conclusion】 In the context of continuous enhancement of blood collection and supply standardization in Hebei Province, the blood quality monitoring mechanism based on intra-province consistency can be further studied to standardize intra-province homogenization of blood quality monitoring in multiple links including sampling rules, statistical analysis and data comparison calibers.
