Objective To investigate the level and influencing factors of quality of life in patients with osteoradionecrosis of the jaws (ORNJ) in order to provide theory basis for nursing intervention. Methods Ninety-five patients hospitalized from January 2015 to Febury 2017 and participated in the investigation by a convenient sampling method. The functional assessment of cancer therapy-head and neck (FACT-H&N), social support rating scale (SSRS) and general information questionnaire were used to assess the quality of life, social support and basic information in ORNJ patients in our hospital respectively. Results The score of quality of life was (79.99 ±15.72). The index value of common module of quality of life was higher than that of additional concern. The average scores of each dimension of common module from low to high were as follows: functional well-being, social/family well-being, physical well-being and emotional well-being. The multiple linear regression analysis showed that the influencing factors of quality of life were social support, severe mouth opening difficulty (grade Ⅲ and Ⅳ), the course of primary disease (3 ～5 years, 5 ～10 years), which explained 35.6％variation in the quality of life. Conclusions The quality of life of ORNJ patients is generally lower than that of other head and neck cancer patients. The social support, severe mouth opening difficulty and course of primary disease can affect the patients' quality of life.The smaller the mouth opening (≤1 cm), the longer the course of primary disease (3～5 years) and the worse the quality of life is. Thus, nursing staff should pay attention to the quality of life of ORNJ patients and give prospective nursing intervention to improve the quality of life according to the characteristics of the development of the disease.

Objective: To investigate the effects of physical activity (PA) intensity and sedentary behavior (SB) on calcanues bone mineral density (BMD) in preschool children, so as to provide a basis for rationalizing the daily physical activity of preschool children to promote bone health. Methods: A total of 673 pre school children aged 3-6 years from nine kindergartens in Pingxiang City, Ganzhou City and Yingtan City of Jiangxi Province, were selected from September to December 2021 by using the whole stratified cluster random sampling method. The PA levels and SB were measured by using a three axis acceleration sensor, and left calcanues BMD was measured by an ultrasound bone densitometer. Multiple linear regression was used to explore the effects of changes in PA on calcanues BMD in pre school children of all ages. Results: Of the 673 preschoolers surveyed, 498 (74.0%) achieved an average of ≥60 min of moderate to vigorous physical activity (MVPA) per day, there were 265 boys (71.2%), and 233 girls ( 77.4 %). The difference between genders was not statistically significant ( χ 2=2.77, P >0.05). There was no statistically significant difference in the BMD test of the calcaneus bones of preschoolers by gender ( Z=0.42, P >0.05). The difference in BMD results of pre school children with 3, 4, 5 to 6 years was statistically significant ( H=2.65, P <0.05). Correlation analysis revealed a negative correlation between SB duration and calcaneus BMD ( r =-0.13), and a positive correlation between low intensity physical activity (LPA) duration, MVPA duration, and calcaneus BMD ( r =0.14, 0.25 ) ( P <0.05). Multivariate linear regression analysis showed that SB duration negatively correlated with calcaneus BMD, whereas LPA and MVPA duration positively correlated with calcaneus BMD ( P <0.05). Conclusions MVPA duration is positively correlated with the growth of BMD in the heel bone and negatively correlated with SB. The kindergartens can adjust their curricula according to the physical and mental developmental characteristics, gender and age differences of pre school children, increase the time of outdoor activities, and reduce the sedentary time to promote the bone health of young children.

Objective To study the levels of serum Periostin and interleukin(I1-)-18 in preterm infants with bronchopulmonary dysplasia(BPD),and to analyze their correlation with the severity of the disease and their predictive value for BPD.Methods A total of 62 preterm infants with BPD diagnosed and treated in the hospital from January 2019 to January 2022 were retrospectively selected as the BPD group,and 80 preterm in-fants without BPD during the same period were selected as the non-BPD group.According to the severity of BPD,the infants with BPD were divided into mild subgroup(22 cases),moderate subgroup(24 cases)and se-vere subgroup(16 cases).The serum levels of Periostin and IL-18 were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the correlation between the clinical parameters.Multivariate Logistic regression was used to analyze the influencing factors of BPD,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for BPD.Results Compared with the non-BPD group,the BPD group had a significantly higher proportion of infants with pulmonary surfactant(PS)use,neonatal respiratory distress syndrome,apnea,patent ductus arteriosus,and serum levels of Periostin and IL-18,as well as a significantly longer duration of mechanical ventilation,noninvasive respiratory support,and length of hospital stay.The lung function parameters[tidal volume per kilogram(VT/kg),ratio of time to peak tidal expiratory flow to time(TPTEF/TE),ratio of volume to peak tidal expiratory flow to volume(VPEF/VE),expiratory flow at 50％tidal volume(50％TEF),expiratory flow at 75％tidal volume(75％TEF)]and 1,5 min Apgar score of BPD group were lower than that of non-BPD group,and the differences were statistically significant(P＜0.05).The serum levels of Periostin and IL-18 in mild subgroup,moderate subgroup and severe subgroup were increased in turn.The levels of serum Periostin and IL-18 were negatively correlated with pulmonary function indexes(VT/kg,50％TEF,75％TEF,TPTEF/TE,VPEF/VE,P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for BPD(P＜0.05),and PS was a protective factor(P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for the severity of BPD(P＜0.05).The area under the curve(95％CI)of serum Periostin and IL-18 alone and in combination for predicting BPD were 0.841(0.814-0.899),0.863(0.820-0.897),0.922(0.878-0.949),respectively.The sensitivity and specificity of combined prediction were 0.902 and 0.825,respectively.The area under the curve of the combination of the two indica-tors for predicting BPD was greater than that of each index alone,and the difference was statistically signifi-cant(Z=5.357,4.894,P＜0.001).Conclusion The levels of serum Periostin and IL-18 are increased in in-fants with BPD,which are related to the severity of BPD and lung function.The combination of serum Perios-tin and IL-18 has a high predictive value for BPD.

The paper reports a case of 2,8-dihydroxyadenine (2,8-DHA) crystalline nephropathy caused by mutation of adenine phosphoribosyltransferase ( APRT) gene. The female patient was 60 years old, and sought medical advice due to "foaming urine increased for half a year". Renal biopsy result showed irregular yellowish brown 2,8-DHA crystals with refraction under polarized light. 2,8-DHA crystals were found by urine sediment detection, and homozygous deletion of c.521_523delTCT on exon 5 of APRT gene was found by genetic testing. Finally this patient was diagnosed as 2,8-DHA crystalline nephropathy. Renal function improved after treatment with allopurinol. The case report aims to improve the clinician's understanding of 2,8-DHA crystalline nephropathy. Early recognition, correct diagnosis, and early drug intervention may delay the progression of renal failure and improve the prognosis.
