Objective:To investigate the effect of five-element music therapy combined with meridian-based acupoint massage timed according to qi circulationon on negative emotions and sleep quality in older adults with chronic heart failure. Methods:A total of 112 older adult patients with chronic heart failure who received treatment at The Affiliated Hospital of Hangzhou Normal University between January 2022 and June 2023 were included in this study. They were randomly divided into a control group ( n = 56) and a study group ( n = 56) using the random number table method. Based on conventional treatment, the control group received five-element music therapy, while the intervention group underwent a combination of five-element music therapy and meridian-based acupoint massage timed according to qi circulation. Before and after the intervention, a comparison was made between the two groups in terms of the scores of the Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI), and various dimensions of the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Additionally, the sleep outcome and patient satisfaction were also compared between the two groups. Results:After intervention, the scores of the HAMA and HAMD in the study group were (11.29 ± 2.48) points and (12.48 ± 3.36) points, respectively. In contrast, the control group had scores of (15.93 ± 3.35) points and (16.50 ± 4.32) points, respectively. After intervention, the scores of the HAMA and HAMD scales in both the study and control groups demonstrated a significant reduction in comparison with their respective pre-intervention scores [study group: (20.13 ± 5.18) points, (23.95 ± 8.97) points, control group: (19.36 ± 5.45) points, (23.79 ± 7.61) points, t = 15.35, 10.24, 5.65, 8.93, all P < 0.001). After intervention, the scores of the HAMA and HAMD scales in the study group were significantly lower than those in the control group ( t = -8.34, -5.49, both P < 0.001). After intervention, the scores of the PSQI in the study and control groups were (7.05 ± 0.96) points and (9.91 ± 1.28) points, respectively. After intervention, the scores of PSQI in both the study and control groups demonstrated a significant reduction compared with their respective pre-intervention scores [study group: (12.98 ± 2.21) points, control group: (12.50 ± 2.48) points, t = 24.68, 9.79, both P < 0.05]. After intervention, the score of the PSQI in the study group was significantly lower than that in the control group ( t = 13.34, P < 0.05). Based on the scores across various dimensions of the MLHFQ, it was observed that after intervention, the scores of emotional, physical, and other domains in both the study and control groups [study group: (9.36 ± 2.29) points, (16.95 ± 3.80) points, (18.50 ± 2.33) points; control group: (12.93 ± 2.00) points, (19.98 ± 3.98) points, (20.04 ± 2.24) points] decreased significantly compared with their pre-intervention scores [study group: (15.57 ± 1.55) points, (26.23 ± 4.63) points, (21.18 ± 2.50) points, control group: (16.09 ± 1.87) points, (25.32 ± 4.40) points, (21.57 ± 2.69) points, t = 21.66, 18.55, 8.44, 11.29, 11.73, 4.61, all P < 0.001]. After intervention, the scores of emotional, physical, and other domains in the study group were significantly lower than those in the control group ( t = -8.79, -4.13, -3.56, all P < 0.05). Patient satisfaction in the study group was superior to that that in the control group [98.21% (55/56) vs. 87.50% (49/56), χ2 = -3.09, P < 0.05]. Total effective rate of intervention on sleep in the study group was significantly higher than that in the control group [92.86% (52/56) vs. 78.57% (44/56), χ2 = -2.09, P < 0.05]. Conclusion:Five-element music therapy combined with meridian-based acupoint massage timed according to qi circulationon in the treatment of chronic heart failure in older adults can effectively alleviate negative emotions, improve the quality of life and sleep, and increase patient satisfaction with nursing care.

The spinal vertebra defect were restored by using 3D printing patient-matched artificial vertebral body after tumor resection. All patients who accepted TES and 3D printing patient-matched artificial vertebral body implantation were included according to the inclusion and exclusion criteria. The bone interface fusion was evaluated by the imaging fusion criteria of Brantigan and Steffee at 3 and 6 months after operation, the curative effect was evaluated by comparing Japanese Orthopaedic Association (JOA) score at 3 and 6 months after operation, visual analogue scale (VAS) 3 months after operation and intervertebral height at 3 and 6 months after operation with those before operation, and the safety was evaluated by adverse event recording.Results:All 12 patients completed the operation successfully, and the operation sites were thoracic vertebrae in 6 cases (50%), thoracolumbar in 3 cases (25%) and lumbar vertebrae in 3 cases (25%). All patients were followed up. The mean follow-up time was 23.92±3.23 months (range, 19-29 months). No tumor recurrence or metastasis was observed during this period. All patients were followed up at 15 days, 3 months and 6 months after operation. During the 6-month follow-up, X ray results showed that interface of bone and the vertebral body were fused in all of the 12 patients, and the effective rate of fusion was 100%. The 95% confidence interval is calculated to be (75.6%-100%). Six months after operation, the improvement rate of JOA score was excellent in 10 cases, good in 1 case, poor in 1 case, and the excellent and good rate was 91.66%. The preoperative VAS score was 4.08 ±2.47, and during the 3-month follow-up, the VAS score was improved to 1.83 ±1.59. Compared with the preoperative VAS score, the difference was statistically significant ( t=2.635, P=0.023). The intervertebral height before operation, 15 days after operation, 3 months after operation and 6 months after operation were 32.75 (25.94, 68.20), 41.09 (30.55, 70.20), 40.70 (30.23, 67.83) and 40.74 (30.23, 67.08), respectively, and there was no statistically significant difference (χ 2=0.768, P=0.857). No implant-related adverse events occurred after operation. Conclusion:The 3D printing patient-matched artificial vertebral body used in this study has satisfactory short-term efficacy and safety in the reconstruction of spinal stability after spinal tumor resection.

The incidence and risk factors of early hyperglycemia in extremely preterm infants / 中国新生儿科杂志

Objective:To study the incidence and risk factors of early hyperglycemia in extremely preterm infants (EPIs).Methods:From January 2018 to December 2021, EPIs with gestational age (GA) <28 w born in our hospital and admitted to the neonatal department were retrospectively studied. According to the occurrence of early hyperglycemia (within 1 w after birth), the infants were assigned into hyperglycemia group and non-hyperglycemia group. Univariate and logistic regression were used to analyze the risk factors of early hyperglycemia in EPIs.Results:A total of 218 cases of EPIs were enrolled, including 70 (32.1%) in the hyperglycemia group and 148 (67.9%) in the non-hyperglycemia group. The incidence of early hyperglycemia in EPIs with GA<25 w was 10/20 and 11/16 in EPIs with birth weight (BW) ≤700 g. The GA and BW of the hyperglycemia group were significantly lower than the non-hyperglycemia group ( P<0.05). More infants in the hyperglycemia group had 1-min and 5-min Apgar≤7 than the non-hyperglycemia group ( P<0.05). Logistic regression analysis showed that increased BW ( OR=0.995, 95% CI 0.993~0.997, P<0.05) was a protective factor for early hyperglycemia in EPIs, while male gender ( OR=2.512,95% CI 1.232~5.123, P<0.05), vasoactive drug use during the first week of life ( OR=2.687, 95% CI 1.126~6.414, P<0.05), maternal hypertension during pregnancy ( OR=14.735, 95% CI 1.578~137.585, P<0.05) were risk factors for early hyperglycaemia in EPIs. Conclusions:Early hyperglycemia are common among EPIs. Low BW, male gender, vasoactive drug use during the first week of life and maternal hypertension during pregnancy may increase the risk of early hyperglycemia.

Risk factors of extrauterine growth retardation in very preterm infants with birth weight less than 1 500 g / 中国新生儿科杂志

Objective:To study the risk factors of extrauterine growth retardation (EUGR) during hospitalization in very preterm infants (VPIs) with birth weight (BW) <1 500 g.Methods:From Jan 2015 to Dec 2020, clinical data of VPIs admitted to neonatal department our hospital were retrospectively studied. The infants were assigned into EUGR group and non-EUGR group according to their weight at discharge. Multivariate logistic regression analysis was used to analyze the risk factors of EUGR in VPIs.Results:A total of 969 VPIs were enrolled, including 400 cases of EUGR (41.3%). Multivariate logistic regression analysis showed that Z-score of BW ( OR=0.057, 95% CI 0.037-0.088, P<0.001) was closely correlated with the occurrence of EUGR and growth velocity (GV) after regain BW ( OR=0.537, 95% CI 0.479-0.602, P<0.001) was a protective factor for EUGR. Maternal hypertension during pregnancy ( OR=1.895, 95% CI 1.059-3.394, P=0.031), asphyxia at birth ( OR=2.508, 95% CI 1.265-3.347, P=0.004) and moderate to severe bronchopulmonary dysplasia (BPD) ( OR=2.660, 95% CI 1.503-4.708, P=0.001) were risk factors for EUGR at discharge. Conclusions:EUGR is still common in VPIs. Increased GV after regain BW, prevention and treatment of moderate to severe BPD may reduce the incidence of EUGR at discharge in VPIs.

Reform and practice of blended teaching of biochemistry and molecular biology in the context of new medicine / 中华医学教育探索杂志

Objective:To investigate the application effect of the blended teaching model of "pre-class synchronous small private online course (SPOC)+ flipped classroom+post-class knowledge expansion" in the theoretical teaching of biochemistry and molecular biology. Methods:A total of 951 students majoring in clinical medicine, preventive medicine, and pharmacy in the class of 2020 in Qiqihar Medical College were selected as teaching reform research group (experimental group), and their curriculum relied on the self-built massive open online course (MOOC) curriculum and the MOOC resources of Chinese universities to construct a blended teaching model; the reform methods such as small class grouping, case-based learning, and diversified examination were adopted to carry out theoretical flipped teaching activities with cross integration of cases and knowledge points as the main line. A total of 847 students majoring in clinical medicine, preventive medicine, and pharmacy in the class of 2019 were selected as control group, and the traditional teaching method was used for theoretical courses. The courses were evaluated by offline assessment and online assessment, and feedback information was collected through examination scores, questionnaire survey, and online voting. SPSS 20.0 was used for statistical analysis, and the t-test was used for comparison between groups. Results:The experimental group had a significantly higher total score of final examination than the control group [(92.12±3.88) vs. (86.73±5.27), P<0.05]. The questionnaire survey showed that the students in the experimental group showed a relatively high degree of satisfaction with the blended teaching reform, which increased their participation, experiencing, and sharing activities. The students majoring in clinical medicine in the class of 2020 believed that they had established clinical thinking ability (263, 92.61%) and become familiar with the clinical manifestations and pathogenesis of common diseases (262, 92.25%); the students majoring in preventive medicine in the class of 2020 believed that they had increased their awareness of serving the public (151, 93.21%) and developed the ability to teach and guide healthy living (148, 91.36%); the students majoring in pharmacy in the class of 2020 believed that they had mastered the mechanism of action of drugs for disease treatment (138, 93.24%) and understood the importance of rational drug use in clinical practice (135, 91.22%). Conclusion:The blended teaching model realizes student-centered teaching, stimulates the interest and initiative in learning, and improves learning outcome, thereby improving teaching quality to a certain extent.

Inhibitory effect of chikusetsusaponin IVa on proliferation of triple negative breast cancer cells / 药学学报

Chikusetsusaponin IVa (CsIVa) is a natural active monomer of triterpene saponins in the Chinese herbal medicine of Panax japonicus, which has anti-inflammatory, anti-tumor and other effects. However, its function and mechanism in triple negative breast cancer (TNBC) remain unclear. This study investigated the inhibitory effect and mechanisms of CsIVa on the proliferation of triple negative breast cancer cell line MDA-MB-231. In this study, we found that CsIVa could significantly inhibit the proliferation of MDA-MB-231 cells and eliminate its potential toxic effect on normal breast cells (MCF-10A). The transcriptome sequencing results showed that the inhibition of proliferation of MDA-MB-231 cells by CsIVa was closely related to cell cycle and the pathway regulating cell cycle. Further studies confirmed that CsIVa blocked the cell cycle in G2/M phase by down-regulating the expression of cyclin dependent kinase 1 (CDK1), cyclin B1 and up-regulating the expression of cyclin dependent kinase inhibitor 1A (p21). Moreover, CsIVa can block cell cycle through inhibiting PI3K/AKT signal pathway. In conclusion, CsIVa regulates the expression of cell cycle related proteins (p21, CDK1, cyclin B1) via inhibiting the activity of PI3K/AKT signaling pathway, blocks TNBC cell cycle, and thus exerts its anti-tumor activity.

Aldolase B attenuates clear cell renal cell carcinoma progression by inhibiting CtBP2 / 医学前沿

Aldolase B (ALDOB), a glycolytic enzyme, is uniformly depleted in clear cell renal cell carcinoma (ccRCC) tissues. We previously showed that ALDOB inhibited proliferation through a mechanism independent of its enzymatic activity in ccRCC, but the mechanism was not unequivocally identified. We showed that the corepressor C-terminal-binding protein 2 (CtBP2) is a novel ALDOB-interacting protein in ccRCC. The CtBP2-to-ALDOB expression ratio in clinical samples was correlated with the expression of CtBP2 target genes and was associated with shorter survival. ALDOB inhibited CtBP2-mediated repression of multiple cell cycle inhibitor, proapoptotic, and epithelial marker genes. Furthermore, ALDOB overexpression decreased the proliferation and migration of ccRCC cells in an ALDOB-CtBP2 interaction-dependent manner. Mechanistically, our findings showed that ALDOB recruited acireductone dioxygenase 1, which catalyzes the synthesis of an endogenous inhibitor of CtBP2, 4-methylthio 2-oxobutyric acid. ALDOB functions as a scaffold to bring acireductone dioxygenase and CtBP2 in close proximity to potentiate acireductone dioxygenase-mediated inhibition of CtBP2, and this scaffolding effect was independent of ALDOB enzymatic activity. Moreover, increased ALDOB expression inhibited tumor growth in a xenograft model and decreased lung metastasis in vivo. Our findings reveal that ALDOB is a negative regulator of CtBP2 and inhibits tumor growth and metastasis in ccRCC.

A biomimetic nanoplatform for customized photothermal therapy of HNSCC evaluated on patient-derived xenograft models / 国际口腔科学杂志·英文版

Cancer cell membrane (CCM) derived nanotechnology functionalizes nanoparticles (NPs) to recognize homologous cells, exhibiting translational potential in accurate tumor therapy. However, these nanoplatforms are majorly generated from fixed cell lines and are typically evaluated in cell line-derived subcutaneous-xenografts (CDX), ignoring the tumor heterogeneity and differentiation from inter- and intra- individuals and microenvironments between heterotopic- and orthotopic-tumors, limiting the therapeutic efficiency of such nanoplatforms. Herein, various biomimetic nanoplatforms (CCM-modified gold@Carbon, i.e., Au@C-CCM) were fabricated by coating CCMs of head and neck squamous cell carcinoma (HNSCC) cell lines and patient-derived cells on the surface of Au@C NP. The generated Au@C-CCMs were evaluated on corresponding CDX, tongue orthotopic xenograft (TOX), immune-competent primary and distant tumor models, and patient-derived xenograft (PDX) models. The Au@C-CCM generates a photothermal conversion efficiency up to 44.2% for primary HNSCC therapy and induced immunotherapy to inhibit metastasis via photothermal therapy-induced immunogenic cell death. The homologous CCM endowed the nanoplatforms with optimal targeting properties for the highest therapeutic efficiency, far above those with mismatched CCMs, resulting in distinct tumor ablation and tumor growth inhibition in all four models. This work reinforces the feasibility of biomimetic NPs combining modular designed CMs and functional cores for customized treatment of HNSCC, can be further extended to other malignant tumors therapy.

A hnRNPA2B1 agonist effectively inhibits HBV and SARS-CoV-2 omicron in vivo

The twenty-first century has already recorded more than ten major epidemics or pandemics of viral disease, including the devastating COVID-19. Novel effective antivirals with broad-spectrum coverage are urgently needed. Herein, we reported a novel broad-spectrum antiviral compound PAC5. Oral administration of PAC5 eliminated HBV cccDNA and reduced the large antigen load in distinct mouse models of HBV infection. Strikingly, oral administration of PAC5 in a hamster model of SARS-CoV-2 omicron (BA.1) infection significantly decreases viral loads and attenuates lung inflammation. Mechanistically, PAC5 binds to a pocket near Asp49 in the RNA recognition motif of hnRNPA2B1. PAC5-bound hnRNPA2B1 is extensively activated and translocated to the cytoplasm where it initiates the TBK1-IRF3 pathway, leading to the production of type I IFNs with antiviral activity. Our results indicate that PAC5 is a novel small-molecule agonist of hnRNPA2B1, which may have a role in dealing with emerging infectious diseases now and in the future.

The medical case records data of Jiusheng was collected, the frequency statistic was analyzed based on Python3.8.6, complex network analysis was performed using Gephi9.2 software, community analysis was performed by the ancient and modern medical case cloud platform V2.3.5, and analysis and verification of correlation graph and weight graph were proceed by Neo4j3.5.25 image database. The disease systems with frequency≥10 % were surgery, ophthalmology and otorhinolaryngology, locomotor, digestive and respiratory systems. The diseases under the disease system were mainly carbuncle, arthritis, lumbar disc herniation and headache. The commonly used moxibustion methods were fumigating moxibustion, blowing moxibustion, direct moxibustion and warming acupuncture. The core prescription of points obtained by complex network analysis included Yatong point, Zhiyang(GV 9), Sanyinjiao(SP 6), Dazhui(GV 14), Zusanli(ST 36), Lingtai(GV 10), Xinshu(BL 15), Zhijian point and Hegu(LI 4), which were basically consistent with high-frequency points. A total of 6 communities were obtained by community analysis, corresponding to different diseases. Through the analysis of correlation graph, 13 pairs of strong association rule points were obtained. The correlation between Zhiyang(GV 9)-Dazhui(GV 14) and Yatong point-Lingtai(GV 10) was the strongest. The acupoints with high correlation with Yatong point were Zhiyang(GV 9), Lingtai(GV 10), Dazhui(GV 14), Zusanli(ST 36) and Sanyinjiao(SP 6). In the weight graph of the high-frequency disease system, the relationship of the first weight of the surgery system disease was fumigating moxibustion-carbuncle-Yatong point, and the relationship of the first weight of the ophthalmology and otorhinolaryngology system disease was blowing moxibustion-laryngitis-Hegu (LI 4).

Correlation between dyslipidemia and rheumatoid arthritis associated interstitial lung disease / 北京大学学报(医学版)

OBJECTIVE@#To study the correlation between dyslipidemia and rheumatoid arthritis associa-ted interstitial lung disease (RA-ILD) by retrospective analysis of the clinical data.@*METHODS@#The clinical data of patients with rheumatoid arthritis (RA), who were hospitalized in the Department of Rheumatism and Immunology of Peking University Shenzhen Hospital from January 2015 to July 2020 and fulfilled the criteria of the 2010 Rheumatoid Arthritis Classification Criteria established by American College of Rheumatology/European League Against Rheumatism collaborative initiative, were collected and analyzed.@*RESULTS@#There were 737 RA patients included, of whom 282(38.26%)were with interstitial lung disease (ILD). The median time from the onset of the first RA-related clinical symptoms to the onset of ILD was 13 years (95%CI 11.33-14.67). By multivariate Logistic regression analysis, we found that low-density lipoprotein cholesterol (LDL-C) was an independent risk factor for RA-ILD (OR 1.452, 95%CI 1.099-1.918, P=0.009), whereas high-density lipoprotein cholesterol (HDL-C) was a protective factor for RA-ILD (OR 0.056, 95%CI 0.025-0.125, P < 0.001). The RA patients with high LDL-C or low HDL-C had higher incidence of ILD than that of the RA patients with normal LDL-C or HDL-C(57.45% vs. 36.96%, P < 0.001; 47.33% vs. 33.81%, P < 0.001, respectively). The median time of ILD onset in the RA patients with low HDL-C was shorter than that of the RA patients with normal HDL-C [10.0(95%CI 9.33-10.67)years vs.17.0 (95%CI 14.58-19.42) years, P < 0.001]. HDL-C level was negatively correlated with disease activity. Among the RA-ILD patients, the patients with low HDL-C had higher percentage of usual interstitial pneumonia (UIP) then that of the patients with normal HDL-C (60.00% vs. 53.29%, P=0.002). The RA-ILD patients with high LDL-C had higher incidence rate of decrease in forced vital capacity (FVC) than that of the RA-ILD patients with normal LDL-C (50.00% vs. 21.52%, P=0.015). The RA-ILD patients with low HDL-C had higher incidence rate of decrease in FVC (26.92% vs. 16.18%, P=0.003) and carbon monoxide diffusion (80.76% vs. 50.00%, P=0.010) than that of RA-ILD patients with normal HDL-C.@*CONCLUSION@#LDL-C was possibly a potential independent risk factor for RA-ILD. HDL-C was possibly a potential protective factor for RA-ILD. HDL-C level was negatively correlated with disease activity of RA. The median time of ILD onset in the RA patients with low HDL-C was significantly shorter than that of the RA patients with normal HDL-C.

Distribution characteristics of tumor infiltrating lymphocytes in EBV-associated lymphoepithelioma-like carcinoma and their clinical significance / 中华病理学杂志

Objective: To investigate the association between the distribution of tumor infiltrating lymphocytes (TIL) in EBV associated lymphoepitheliomatoid carcinoma (LELC) and the pathological subtypes of LELC, as well as the clinical significance of TIL distribution. Methods: The LELC patients with sufficient tumor tissues, complete clinical data and positive EBER, who visited Zhejiang Cancer Hospital, Hangzhou, China from January 2006 to October 2018, were selected. Various immunohistochemical markers (CD20, CD138, CD4, CD8, CD56 and FOXP3) were examined for TIL typing. Two pathologists reviewed the hematoxylin and eosin (HE) staining sections and interpreted the immunohistochemical results. Correlation analysis was used to evaluate the relationship between the distribution of TIL subgroups and LELC's pathological characteristics. Survival analyses were conducted to study the prognostic values of TIL subgrouping. Results: A total of 102 patients with EBV related LELC were included. 46 of them were classic LELC (c-LELC) with rich interstitial TIL, and 56 were non-classic LELC (n-LELC) with relatively fewer interstitial TIL. The results of TIL analysis showed that all subtypes of c-LELC were rich in TIL, with B lymphocytes as the dominant subgroup. The number of TIL in n-LELC was fewer than that in c-LELC, with T lymphocytes as the dominant subgroup. There was no significant difference in the distribution of plasma cells between the two groups. Survival analysis showed that the total number of TIL, and the infiltrations of CD20+B cells, CD4+T cells, and FOXP3+Treg cells were associated with better overall survivals (P=0.004, 0.003, 0.008 and 0.025, respectively) and disease-free survivals (P=0.011, 0.003, 0.038 and 0.041, respectively) in patients with LELC. Conclusions: The morphologic subtypes of EBV-related LELC have different tumor immune characteristics. The total number of TIL in the stroma of c-LELC is significantly higher than that of n-LELC. Interestingly, B lymphocytes are the dominant TIL in c-LELC, while T lymphocytes are the dominant TIL in n-LELC. The infiltration of TIL, CD20+B cells, CD4+T cells and FOXP3+Treg cells in LELC may suggest a better prognosis.

Clinical and imaging features of infective sacroiliitis in children / 中华儿科杂志

Objective: To summarize the clinical, radiological characteristics, and prognosis of infectious sacroiliitis in children. Methods: A case-control study was conducted, including 12 cases of infectious sacroiliitis diagnosed in the Rheumatology and Immunology Department of the Children's Hospital affiliated with the Capital Institute of Pediatrics from June 2018 to June 2023. These cases comprised the case group. Concurrently, 28 cases of pediatric idiopathic arthritis involving the sacroiliac joint in the same department served as the control group. Basic patient information, clinical features, laboratory parameters, and clinical treatment outcomes for both groups were collected and analyzed. Independent sample t-tests and chi-squared tests were used for inter-group comparisons. Results: Among the 12 cases in the case group, there were 5 males and 7 females, with a disease duration of 0.8 (0.5, 1.2) months. Nine patients presented with fever, and 1 patient had limping gait. Human leukocyte antigen (HLA)-B27 positivity was observed in 1 case, and there was no family history of ankylosing spondylitis. In the control group of 28 cases, there were 19 males and 9 females, with a disease duration of 7.0 (3.0, 17.0) months. One patient (4%) had fever, and 14 cases (50%) exhibited limping gait. HLA-B27 positivity was found in 18 cases (64%), and 18 cases (64%) had a family history of ankylosing spondylitis. The case group had higher white blood cell count (WBC), neutrophil ratio, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, as well as a higher proportion of unilateral involvement on magnetic resonance imaging and bone destruction on CT compared to the control group ((11.1±6.2)×109 vs. (7.3±2.3)×109/L, 0.64±0.10 vs. 0.55±0.12, 72 (34, 86) vs. 18 (5, 41) mm/1 h, 24.6 (10.1, 67.3) mg/L vs. 3.6 (0.8, 15.0) mg/L, 11/12 vs. 36% (10/28), 9/12 vs. 11% (3/28), t=2.90, 3.07, Z=-2.94, -3.28, χ2=10.55, 16.53, all P<0.05). Conclusions: Pediatric infectious sacroiliitis often presents as unilateral involvement with a short disease history. Elevated WBC, CRP, and ESR, as well as a high rate of bone destruction, are also common characteristics.

Analysis of etiology and complications in children with stage 5 chronic kidney disease / 中华儿科杂志

Objective: To investigate the etiology, complications, and prognostic factors of stage 5 chronic kidney disease (CKD5) in children. Methods: A case series study was conducted to retrospectively analyze the general situation, clinical manifestations, laboratory tests, genetic testing, and follow-up data (until October 2022) of 174 children with CKD5 who were diagnosed and hospitalized at the Children's Hospital of Chongqing Medical University from April 2012 to April 2021. The characteristics of complications in the children were compared based on age, gender, and etiology. Based on the presence or absence of left ventricular hypertrophy (LVH), patients were divided into LVH group and non LVH group for analyzing the influencing factors of cardiovascular disease. Patients were also divided into death group and survival group, peritoneal dialysis group and hemodialysis group based on the follow-up data for analyzing the prognostic factors. The chi-square test, independent sample t-test, Fisher exact probability test, Mann-Whitney U test and Kruskal Wallis test were used to analyze data among different groups. Multivariate Logistic regression analysis was used to identify the prognostic factors. Results: A total of 174 children with CKD5 were enrolled in the study (96 boys and 78 girls), aged 11.2 (8.2, 13.0) years. Congenital kidney and urinary tract malformations (CAKUT) were the most common causes of the CKD5 (84 cases, 48.3%), followed by glomerular diseases (83 cases, 47.7%), and among which 28 cases (16.1%) were hereditary glomerular diseases. The common complications of CKD5 included anemia (98.2%, 165/168), mineral and bone disorder in chronic kidney disease (CKD-MBD) (97.7%, 170/174), lipid metabolism disorders (87.5%, 63/72), hypertension (81.4%, 127/156) and LVH (57.6%,57/99). The incidences of hypertension in primary glomerular disease were higher than that in CAKUT(93.8%(30/32) vs.73.7%(56/76),χ2=5.59,P<0.05). The incidences of hypertension in secondary glomerular disease were higher than that in CAKUT and that in hereditary kidney disease (100.0%(20/20) vs. 73.7%(56/76), 68.2%(15/22), both P<0.05). The incidence of hypocalcemia in CAKUT, primary glomerular disease, and hereditary kidney disease was higher than that in secondary glomerular disease (82.1%(69/84), 88.2%(30/34), 89.3%(25/28) vs. 47.6%(10/21), χ2=10.21, 10.75, 10.80, all P=0.001); the incidence of secondary hyperparathyroidism in women was higher than that in men (80.0%(64/80) vs. 95.0%(57/60), χ2=6.58, P=0.010). The incidence of LVH in children aged 6-<12 was higher than that in children aged 12-18 (73.5%(25/34) vs. 43.1%(22/51), χ2=7.62, P=0.006). Among 113 follow-up children, the mortality rate was 39.8% (45/113). Compared to the survival group, the children in the death group had lower hemoglobin, higher blood pressure, lower albumin, lower alkaline phosphatase and higher left ventricular mass index ((67±19) vs. (75±20) g/L, 142 (126, 154) vs. 128(113, 145) mmHg(1 mmHg=0.133 kPa), (91±21) vs. (82±22) mmHg, 32 (26, 41) vs. 40 (31, 43) g/L, 151 (82, 214) vs. 215 (129, 37) U/L, 48 (38, 66) vs. 38(32, 50) g/m2.7,t=2.03, Z=2.89, t=2.70, Z=2.49, 2.79, 2.29,all P<0.05), but no independent risk factors were identified (all P>0.05). The peritoneal dialysis group had better alleviation for anemia, low calcium, and high phosphorus than the hemodialysis group ((87±22) vs. (72±16) g/L, (1.9±0.5) vs. (1.7±0.4) mmol/L, (2.2±0.7) vs. (2.8±0.9) mmol/L, t=2.92, 2.29, 2.82, all P<0.05), and the survival rate of the peritoneal dialysis group was significantly higher than that of the hemodialysis group (77.8% (28/36) vs. 48.4% (30/62), χ2=8.14, P=0.004). Conclusions: CAKUT is the most common etiology in children with CKD 5, and anemia is the most common complication. The incidence of complications in children with CKD 5 varies with age, gender and etiology. Anemia, hypertension, hypoalbuminemia, reduced alkaline phosphatase and elevated LVMI may be the prognostic factors in children with CKD5. Peritoneal dialysis may be more beneficial for improving the long-term survival rate.
