Objective To summarize clinical characteristics of primary nephrotic syndrome (PNS) in children. Methods The clinical and laboratory data of 964 children with PNS (including 747 new cases) were retrospectively analyzed,who were admitted between 1 August,1996 to 31 July,2006. Results Of 747 cases,568 were males and 179 females,with a median age of 4.7 years (0.3-17.3). The total number of children with PNS aged from 1 to 5 years was 385 (51.5%). Compared with children with nephritic type nephrotic syndrome (NNS),children with simple type nephrotic syndrome (SNS) had lower albumin (P0.05); Compared with normal values,children with PNS had lower IgG (P0.05). Main motivation of PNS relapse in children was upper respiratory infection,followed by irregular administration of glucocorticoids. Conclusion Children aged from 1 to 5 years are susceptible to PNS. There is humoral immunological dysfunction in PNS children. In the treatment of PNS,to relieve hyperlipidemia and to prevent and control infections is the key point. To strengthen propaganda and guidance about PNS is important as well.

This study was aimed to confirm animal model and evaluating indicators of the chronic obstructive pulmonary disease combined with pulmonary interstitial fibrosis (PIF-COPD). PIF-COPD rats were induced by intratracheal administration of Bleomycin(BLM, 6 mg·kg-1) and cigarette smoke stimulation for 47 days. After that, the lung function and index were measured. Changes of pathomorphism of lung were observed with hematoxylin-eosin staining. Collagen protein I and III were determined by Sirius red staining. The protein antibody microarray chip was employed for serum cytokine expression pattern measurement. The results showed that in the lung function testing, the central airway resistance, tissue damping, dynamic elasticity of model rats increased significantly and the dynamic compliance reduced significantly. The lung index of model rats increased significantly (compared with the control group, P < 0.01). The pathological tests showed that lung tissues of model rats showed emphysema and fibration with inflammatory infiltration, and content of collagen type I and III increasing significantly. The contents of MMP-8, TIMP-1, IL-10, IL-13, PDGF-AA, Beta-NGF of model rats serum increased obviously compared with the control group and RAGE reduced compared with the normal control. It was concluded that rats which were induced by intratracheal administration of BLM (6 mg·kg-1) and cigarette smoke stimulation for 47 days can be used as animal model establishment of PIF-COPD. The respiratory function and serum levels of MMP-8, TIMP-1, IL-13, PDGF and NGF can be used as evaluating indicators of PIF-COPD model.

Aim To investigate the roles of chloride channels in the apoptosis and apoptotic volume de-crease (AVD)induced by adriamycin in nasopharyn-geal carcinoma CNE-2Z cells.Methods Apoptotic rates were detected by flow cytometry,and the volume changes were measured by the time-lapse live cell ima-ging technique.The patch clamp technique was used to record whole-cell chloride currents.Results Adria-mycin induced apoptosis of CNE-2Z cells.An early ap-optotic volume decrease was observed in the cell trea-ted with adriamycin.The cell volume was decreased by about 10% in 2 h.Adriamycin activated a chloride current which showed outward rectification.The chlo-ride channel blocker 5-nitro-2-(3-phenylpropylamino)-benzoate (NPPB ) could inhibit the adriamycin-in-duced chloride currents,apoptosis and prevent cell shrinkage.Conclusions Our findings suggest that ad-riamycin causes cell apoptosis by activation of chloride channels.Chloride channels may be involved in the apoptosis and apoptotic volume decrease induced by adriamycin in CNE-2Z cells.

Objective:To understand the distribution characteristics of pulse oxygen saturation (SpO 2) in the high altitude areas. Methods:From September 2016 to December 2017, all healthy and full-term live births in the First Hospital of Lanzhou University and Dunhuang, Jiuquan, Jingning and Lintao branches were selected as the research objects.Critical congenital heart disease or pulmonary diseases were excluded in advance.SpO 2 in different parts of newborns within 12 hours of birth was measured.Statistical comparisons of SpO 2 in different parts of male and female neonates in the same area and SpO 2 in different parts of different regions were made.The number of SpO 2 and the distribution of percentile difference between the lower limbs and the right upper limb of newborns at different altitude areas were obtained. Results:There were no significant difference between male and female infants in SpO 2 value at any lo-wer extremity and right upper extremity and the difference value in the same area (all P>0.05). There were significant differences in the median ( M) values of SpO 2 and the M value of the difference between the two values of any lower limb and right upper limb at different altitudes (all P<0.05). The results showed that the M value of SpO 2 of the right upper limb ( M=96%) in Lanzhou (1 520 m above sea level) was lower than that in Dunhuang (1 138 m above sea level, M=97%) and Jiuquan (1 481 m above sea level, M=97%), and the M value of the difference between the two values ( M=2%) was higher than that in Dunhuang and Jiuquan ( M=1%) ( P<0.05). The M of SpO 2 of any lower limb ( M=96%) and right upper limb ( M=96%) in Jingning areas (1 668 m above sea level) were lower than that in Dunhuang and Jiuquan area (all P<0.05). The median value of SpO 2 of any lower limb ( M=96%) and right upper limb ( M=96%) in Lintao area (1 883 m above sea level) was lower than that in Dunhuang and Jiuquan areas, and the M value of the difference between the two values ( M=2%) was higher than that in Dunhuang and Jiuquan (all P< 0.05). When the altitude was lower than 1 500 m, the M value of SpO 2 was 97%, P3- P97 was 93%-100%; the M value of the difference between any lower limb and right upper limb was 1, and P3- P97 was 0-4.When the altitude was higher than 1 500 m, the M value of SpO 2 was 95%-96%, P3- P97 was 89%-100%; the M value of SpO 2 of an lower limb and right upper limb was 1%-2%, and P3- P97 was 0-9%. Conclusions:The SpO 2 number and percentage distribution of the difference between any lower limb and right upper limb of newborns at different altitudes are different.

Objective:To explore the mediating effect of self-regulation fatigue between acceptance of hearing impairment and work withdrawal behavior in young and middle-aged patients with sudden deafness, so as to provide reference for the formulation of intervention measures for job withdrawal behavior.Methods:A cross-sectional survey was conducted to facilitate the selection of 326 young and middle-aged patients with sudden deafness who were treated in the Department of Otolaryngology, Head and Neck Surgery in the First Affiliated Hospital and the Second Affiliated Hospital of Air Force Military Medical University of the Chinese PLA from February 2021 to January 2022. The survey was carried out by general information questionnaire, the Revised Acceptance Disability Scale, the Self-Regulatory Fatigue Scale, and the Work Withdrawal Behavior Scale. Structural equation model method was used to analyze the mediating effect.Results:The acceptance of hearing impairment score in young and middle-aged patients with sudden deafness was (59.82 ± 10.99) points, the self-regulation fatigue score was (60.38 ± 8.84) points, and the work withdrawal behavior score was (39.06 ± 6.51) points. Self-regulation fatigue was negatively correlated with acceptance of hearing impairment ( r=-0.541, P<0.01). Work withdrawal behavior was negatively correlated with acceptance of hearing impairment ( r=-0.488, P<0.01), and was positively correlated with self-regulation fatigue ( r=0.587, P<0.01). Self-regulation fatigue played a partial mediating effect between the acceptance of hearing impairment and work withdrawal in young and middle-aged patients with sudden deafness, and the mediating effect ratio was 56.30%. Conclusions:The acceptance of hearing impairment can not only directly affect the work withdrawal behavior of young and middle-aged patients with sudden deafness, but also indirectly affect their work withdrawal behavior through self-regulation fatigue. Medical staff should pay attention to the internal relationship between the acceptance of hearing impairment, self-regulation fatigue and work withdrawal behaviors, so as to improve the acceptance of hearing impairment of patients, relieve their self-regulation fatigue, and avoid the occurrence of work withdrawal behaviors.
