ObjectiveTo explore the suitability of four qualitative research methods in the development of TCM scale. MethodsTaking the development of "Seven Emotions Scale" as an example， we conducted semi-structured interviews with 31 patients of emotional disorders and 10 healthy people by objective sampling， and collected psychological feelings and emotional cognition data related to seven emotions according to the interview outline. Two qualitative methods， descriptive qualitative research and descriptive phenomenology， were used to analyze the data and construct the item library of the scale. The conceptual framework of the scale was constructed by using commonly used grounded theory and frame analysis. ResultsDuring data analysis， it is found that the themes extracted from descriptive phenomenology were not easily understood by the interviewees， and it is difficult for the researchers to truly achieve the "suspension" required by phenomenology. Considering the feasibility and convenience of the researchers' actual operation， as well as whether the initial purpose of the scale research can be intuitively included in the interviewees' views and feelings， descriptive phenomenology is not suitable for the formation of scale items. Using descriptive qualitative research method to analyze the interview data of healthy people and patients with emotional disorders， 306 and 476 scale items were obtained respectively. Through grounded theory， five selective codes were obtained： physical symptoms， external manifestations， psychological feelings， behaviors and emotional control. Using frame analysis， four themes including physical symptoms， psychological feelings， behavior and emotional cognition were constructed. Both methods can be used to construct the conceptual frame of scale， but the framework analysis is more convenient and can better ensure the transparency of the research. ConclusionDescriptive qualitative research methods can be used to form the item library of TCM scales. Framework analysis is more suitable for the construction of the conceptual framework of the scale than grounded theory， while descriptive phenomenology is not suitable for the development of TCM scales.

The paper reports two cases of lipoprotein glomerulopathy (LPG) in children. The Sanger sequencing results in 2 cases indicated apolipoprotein E gene mutation[c.127 (exon3) C>T, p.R43C (p.Arg43Cys); c.494 (exon4) G>C, p.R165P (p.Arg165Pro),respectively]. Renal pathological presentation of two children showed that a large number of lipoprotein emboli were formed in the glomerular capillary loop, and the diagnosis of LPG was confirmed. The onset of LPG has no specific clinical manifestation, which is easy to be undiagnosed or misdiagnosed. Renal biopsy is a diagnostic means, glucocorticoid treatment is ineffective, and long-term lipid-lowering treatment may be required for LPG.

Objective:To investigate the potential of the antineutrophil cytoplasmic antibody (ANCA) renal risk score (ARRS) in predicting the prognosis of children with ANCA-associated glomerulonephritis (AAGN).Methods:Laboratory testing, renal pathology results, treatment and prognosis of 61 children with AAGN diagnosed by renal biopsy from June 2007 to May 2022 in General Hospital of Eastern Theater Command were retrospectively analyzed.The Kaplan-Meier method was used to evaluate the overall and renal survival of children with AAGN, and risk factors of progression to end stage renal disease (ESRD) were analyzed by Cox regression analysis. Results:Among the 61 children with AAGN, there were 14 males and 47 females with the age of (15.65±3.74) years.According to ARRS, AAGN children were assigned into low-risk group (27 cases), medium-risk group (21 cases) and high-risk group (13 cases). During a median follow-up duration of 46.36 (14.58, 95.62) months, the number of ESRD cases in the high-risk group (9 cases) was significantly higher than that of low-risk group (2 cases) and medium-risk group (3 cases) ( χ2=13.079, P<0.001). Kaplan-Meier survival analysis showed that AAGN children in the high-risk group had the worst renal prognosis ( χ2=5.796, P=0.016), while no significant difference was detected in the overall survival among the 3 groups ( χ2=2.883, P=0.237). Multivariate Cox regression showed that estimate glomerular filtration rate(eGFR)≤15 mL/(min·1.73 m 2) ( HR=9.574, 95% CI: 4.205-25.187, P=0.015) and ARRS ( HR=2.115, 95% CI: 1.206-4.174, P=0.012) were independent risk factors for children with AAGN progress to ESRD.Receiver operating characteristic (ROC) curve analysis results showed that the area under the curve of ARRS for predicting the risk of progressing to ESRD in AAGN children was 0.880 (95% CI: 0.759-1.000), and the optimal cutoff value of ARRS was 5.50, with the sensitivity and specificity of 85.71% and 82.98%, respectively. Conclusions:ARRS was an independent risk factor for children with AAGN progress to ESRD, which had a predictive value for the progression of AAGN to ESRD.

Objective: To investigate the protective effect of Paeoniflorin-6 '-o-benzene sulfonate ( CP-25) on methotrexate (MTX) -induced liver injury in rats． Methods: 40 SD rats were randomly divided into normal group，model group，CP-25 treatment group，CP-25 prevention group and resveratrol prevention group．A rat model of liver injury was established by single intraperitoneal injection of MTX (20 mg / kg) ，the levels of serum alanine aminotransferase (ALT) ，aspartate aminotransferase ( AST) ，superoxide dismutase ( SOD) ，glutathione ( GSH) and malondialdehyde (MDA) were determined by ELISA，the levels of interleukin-1 β (IL-1 β) ，interleukin-6 (IL-6) ， tumor necrosis factor-α (TNF-α) ，B-lymphocyte tumor-2 (Bcl-2) ，Bcl-2-associated X (Bax) ，cytochrome C ( Cyt- C) ，cleaved cysteinyl aspartate specific proteinase8 ( cleaved-cas8 ) ，cleaved cysteinyl aspartate specific proteinase 9 (cleaved-cas9) and reduced nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) containing cysteine were assessed by Western blot. Results: Compared with the normal group，the levels of ALT and AST in MTX-induced liver injury model rats increased (F = 70. 23，P＜0. 01 ; F = 11. 09，P＜0. 05) ，and the liver histopathology showed extensive inflammatory cell infiltration，hepatic lobular structure disorder and hepatocyte swelling. Compared with MTX model group，the levels of ALT and AST in CP-25 prevention group and treatment group were lower (F = 62. 32，86. 86，P＜0. 01 ; F = 16. 35，7. 14，P ＜0. 01 ) ，and the pathological score of liver tissue was lower (F = 18. 33，P＜0. 01 ; F = 15. 47，P＜0. 05) ．Further studies showed that compared with MTX model group， both CP-25 prevention group and treatment group could significantly down-regulate the expression of pro-apoptotic proteins Bax(F = 21. 37，P＜0. 01 ; F = 19. 35，P＜0. 05) ，Cyt-C (FCP-25 prevention group = 7. 21，P＜0. 01) ，cleavedcas8 (FCP-25 prevention group = 12. 32，P＜0. 05) and cleaved-cas9(F = 8. 41，P＜0. 01 ; F = 6. 91，P＜0. 05) ，and upregulate the expression of anti-apoptotic protein Bcl-2 (F = 13. 11，P＜0. 01 ; F = 9. 93，P＜0. 05) . At the same time，compared with MTX model group，CP-25 prevention group and treatment group decreased the levels of IL- 1 β , IL-6 and TNF-α(FCP-25 prevention group = 160. 7，46. 55，28. 89，P＜0. 01) ; FCP-25 treatment group = 127. 4，53. 70，26. 46， P ＜ 0. 01 ) ，down-regulated the levels of MDA and NOX4 ( FCP-25 prevention group = 31. 71，38. 45 ，P ＜ 0. 01 ; FCP-25 treatment group = 27. 89，31. 27，P＜0. 01) ，and up-regulated the level of GSH ( F = 39. 65，29. 04，P ＜0. 01) . Conclusion CP-25 has a good therapeutic and protective effect on hepatotoxicity induced by MTX，and this effect may be related to its inhibition of oxidative stress，inflammatory response，and reduction of apoptosis in liver tissue.

Objective:To analyze the clinicopathologic features and prognosis of children with Henoch-Sch?nlein purpura nephritis (HSPN).Methods:The clinicopathological data of children with HSPN who were followed up for more than 5 years and underwent renal biopsy in Jinling Hospital affiliated to Medical School of Nanjing University from January 2001 to June 2015 were retrospectively analyzed. The follow-up endpoint event was defined as estimated glomerular filtration rate (eGFR)<90 ml·min -1·(1.73 m 2) -1. Participants were divided into two groups according to whether the children had reached the primary endpoint event or not. Cox proportional hazards model was used to analyze the influencing factors of renal poor prognosis in children with HSPN. Kaplan-Meier survival curve method was used for survival analysis, and log-rank test was used to compare the difference of renal cumulative survival rate between segmental sclerosis/adhesion (S1) group and non-segmental sclerosis/adhesion (S0) group. Receiver operating characteristic curve (ROC curve) and area under the curve ( AUC) were used to evaluate the diagnostic value. Results:A total of 130 children with HSPN were enrolled in the study. The median onset age was 11.7(8.6, 13.3) years old, of whom 71 cases were males (54.6%). At a median follow-up time of 100.0(75.8, 119.0) months, 12 cases (9.23%) with HSPN reached the primary endpoint event. Compared with the non-endpoint event group, the endpoint event group had higher proportion of hypertension, higher levels of 24-hour urinary protein, serum cholesterol, serum uric acid, and serum creatinine, and lower levels of serum albumin (all P<0.05). There was no statistical difference in treatment between the two groups (all P>0.05). In terms of pathological features, compared with the non-endpoint event group, the endpoint event group had higher proportion of mesangial hyperplasia (M1), S1, tubular atrophy/interstitial fibrosis (T1/T2) and Glomerulus-Bowman's capsule adhesion (all P<0.05). Multivariate Cox regression model showed that S1 was significantly correlated with renal poor prognosis ( HR=7.739, 95% CI 1.422-42.114, P=0.018). As was revealed in a Kaplan-Meier plot, renal cumulative survival rate in the S1 group was significantly lower than that in the S0 group (log-rank χ2=17.069, P<0.001). The ROC curve showed S1 accurately predicted the outcome ( AUC=0.710, 95% CI 0.549-0.872) with specificity of 0.667(95% CI 0.349-0.901) and specificity of 0.754(95% CI 0.667-0.829). Conclusions:S1 is an independent risk factor affecting renal poor prognosis and has a diagnostic value.

Objective:To investigate the efficacy and safety of Rituximab (RTX) in treating children with refractory steroid-resistant nephrotic syndrome (SRNS).Methods:The clinical data of 10 children with refractory SRNS receiving RTX in the Department of Pediatrics, Jinling Hospital from September 2013 to March 2018 were analyzed retrospectively.Results:The age of onset of 10 children (including 5 males and 5 females) was (4.47±2.75) years old.The renal biopsy showed focal segmental glomerular sclerosis in 5 cases (50%), minimal change nephropathy in 3 cases (30%), IgM nephropathy in 1 case (10%), and mesangial proliferative glomerulonephritis in 1 case (10%). Ten children received RTX treatment (1 or 4 doses; 375 mg/m 2 once; maximum: 500 mg) at the age of (6.74±2.62) years old.There were 8 patients (80%) receiving a single dose of RTX, 1 patient (10%) receiving 3 doses, and 1 patient (10%) receiving 8 doses.The follow-up time was 11.93 (5.17, 25.66) months.The remission rates at the 3-month follow-up, 6-month follow-up and last follow-up were 30% (3 patients), 40% (4 patients), and 40% (4 patients), respectively.The 24-hour urinary proteinuria and serum albumin levels were improved in 10 children after RTX treatment, but there were no significant statistical difference(all P>0.05). No significant difference was found in humoral immunity and renal function before and after RTX treatment (all P>0.05). During the treatment and follow-up, 3 patients (30%) developed infusion reaction, 2 patients (20%) showed severe pulmonary infection, and 1 patient (10%) died of severe pulmonary infection. Conclusions:RTX is effective in treating some children with refractory SRNS, and a long-term follow-up should be conducted to prevent infection.

Objective:To discuss the etiology, clinical manifestations and renal pathological features of acute interstitial nephritis (AIN) in children.Methods:The etiology, clinical manifestations, pathological characteristics, clinical effects and outcome of the children with AIN diagnosed by renal biopsy from January 2010 to December 2019 in Nanjing Jinling Hospital were analyzed retrospectively. The Kaplan-Meier method was used to evaluate the kidney survival rate. Cox regression model was built to analyze the risk factors for developing end-stage renal disease (ESRD) at baseline in AIN children.Results:A total of 51 children with AIN were diagnosed by renal biopsy, including 36 males and 15 females. The age was (12.94±2.55) years old (2-17 years old). The clinical manifestations of AIN in children were various and lack of specificity. Only 2 cases (3.92%) had triad. All of the 51 children with AIN showed acute renal injury (AKI), accompanied by increased serum creatinine and decreased estimated glomerular filtration rate. The stage of AKI was mainly stageⅢ(33 cases, 64.71%). Infection was the main cause (38 cases, 74.51%) and drug factor was the second cause (27 cases, 52.94%) in children with AIN. Nonsteroidal antiinflammatory drugs (NSAIDs) were the main inducers of drug-induced AIN (18 cases, 35.29%). The interstitial inflammatory cell infiltration or interstitial edema was found in 51 children. The infiltration of inflammatory cells was mainly mononuclear cells (46 cases, 90.20%). After 4 weeks of treatment, 32 cases (62.75%), 11 cases (21.57%) and 8 cases (15.69%) showed complete, partial and no recovery of renal function, respectively. After 12 weeks of treatment, 49 cases (96.08%), 0 cases (0) and 2 cases (3.92%) showed complete, partial and no recovery of renal function, respectively. After an average follow-up of 4.0(2.0-15.0) months, 2 case (3.92%) patients developed ESRD. The cumulative survival rates of ESRD at 1 year and 2 years after renal biopsy both were 100%, and renal survival rates at 5 years and 10 years were 96.55% and 72.41%, respectively. Multivariate Cox regression analysis results showed that N-acetyl-β-D-glucosidase (NAG) enzyme level>17.6 U/g·cr ( HR=15.729, 95% CI 1.045-15.977, P=0.042) and IgM deposition in renal tissue ( HR=7.523, 95% CI 1.142-9.541, P=0.033) were independent risk factors for developing ESRD in AIN children. Conclusions:AKI is the main clinical manifestation of AIN in children. The characteritic of renal pathology in AIN is tubulointerstitial lesions. After active treatment, most of the patients have a good prognosis. Prevention of infection and rational use of drugs are the key to reduce the incidence rate of AIN in children. The N-acetyl-β-D-glucosidase enzyme level>17.6 U/g·cr and IgM deposition in renal tissue are independent risk factors for developing ESRD in AIN children.

Objective:To evaluate the enrollment rate, mutation rate and causes of variability the clinical pathway of bronchopneumonia.Methods:The enrollment rate, completion rate, variation and reasons of the clinical pathway in Beijing Children′s Hospital, Capital Medical University from January 2012 to December 2016 were retrospectively collected.Data of patients after the clinical pathway of bronchopneumonia in other tertiary class A hospitals were gathered by questionnaires, and the enrollment rate, completion rate, variation rate and reasons were analyzed.Results:(1)At the end of 2016, 11 of the 13 hospitals included in this study had implemented the clinical pathway for 5 years, 1 hospital for 3 years, and 1 hospital for 2 years.(2) Eleven hospitals provided their enrollment rates.The enrollement rate of 2 hospitals was<50%, and that of 9 hospitals was>80%.The annual completion rate of Beijing Children′s Hospital was ≥75%, and the completion rates offered by 8 hospitals were basically >70%.(3) Since the implementation of the clinical pathway for 5 years in Beijing Children′s Hospital, a total of 427 cases were enrolled of which 93 cases were mutated (variability 21.78%). The variability of 5 hospitals was maintained at <15%.The variability of 3 hospitals decreased with the implementation years, and became qualified.The variability of 1 hospital first rebounded and then controlled; 1 hospital increased by 27.65%; 1 hospital was first controlled and rebounded; 1 hospital was always >15%.The main cause of the mutation was coexisting diseases, complications, progression of the disease, or correction of the first diagnosis, etc.Conclusions:The completion rate of tertiary class A hospitals meets the requirements of national policy.However, the enrollment rate needs to be improved, and the variation rate among different hospitals differs a lot.Further implementation of the clinical pathway should be strengthened and monitored.

To construct a competency model for junior caregivers for the elderly and to provide a reference for the selection, evaluation and training for the junior caregivers for the elderly.
 Methods: Firstly, we drafted the primary competency model for junior caregivers for the elderly through literature review. Then, we used Delphi method to carry out 2 rounds of questionnaire survey for 20 experts to optimize the indicators for primary model. The weight of each indicator is determined by analytic hierarchy process (AHP) and expert sequencing method.
 Results: The effective recovery rates of the two-round questionnaire were 87% and 100%, respectively. The expert authority coefficient was 0.70-0.93, and the average authority coefficient was 0.80. The final version of the competency model for junior caregivers for the elderly included 4 first-grade indexes, 11 second-grade indexes and 37 third-grade indexes.
 Conclusion: The competency model for the junior caregivers for the elderly is reliable and can be used as the reference standard for the selection, evaluation and training for the junior caregivers for the elderly.
