ABSTRACT
Objective:To analyze the clinical characteristics and prognostic factors of high-risk neuroblastoma (HR-NB) patients with skeletal metastasis.Methods:The clinical features of 336 newly treated HR-NB patients with skeletal metastases admitted to the Department of Medical Oncology of Beijing Children′s Hospital, Capital Medical University from January 2007 to December 2018 were analyzed retrospectively.Kaplan-Meier method was used for the survival analysis, and Log- Rank test was used for univariate prognosis analysis.The Cox model was used to analyze the multifactorial prognostic analysis. Results:A total of 336 HR-NB patients were recruited, involving 188 males and 148 females with the median age of onset of at 43 (4-148) months.Skeletal metastases affected the viscerocranium (89 cases, 26.5%), neurocranium (193 cases, 57.4%), vertebrae (298 cases, 88.7%), sternum and ribs (183 cases, 54.5%), pelvis (270 cases, 80.4%), upper limbs (182 cases, 54.2%) and lower limbs (240 cases, 71.4%). The 5-year event-free survival (EFS) rate and overall survival (OS) rate were (30.4±2.7)% and (41.3±2.9)%, respectively.Univariate analysis showed a significantly lower 5-year OS rate in skeletal metastatic HR-NB patients with poor prognostic classification, the morphology of neuroblastoma (stroma-poor) and ganglioneuroblastoma (intermixed), high index of mitosis-karyorrhexis index, lactate dehydrogenase≥587 U/L, serum ferritin≥92 μg/L, MYCN amplification and 1p loss of heterozygosity, and metastases in the viscerocranium, neurocranium, vertebrae, sternum and ribs, pelvis, upper limbs and lower limbs (all P<0.05). The 5-year OS rate of HR-NB patients with all 7 regions of skeletal metastases was only (14.2±5.9)%, which was significantly lower than that in patients with a single region metastasis or multi-region metastases[(66.0±10.2)% vs.(43.6±3.4)%, χ2=45.722, P<0.05]. Cox multifactorial analysis showed that MYCN amplification ( HR=4.165, 95% CI: 2.356-7.363) and the viscerocranium metastasis ( HR=2.560, 95% CI: 1.519-4.315) were the independent risk factors affecting the prognosis of HR-NB patients with skeletal metastases (all P<0.05). Conclusions:The prognosis is extremely poor in HR-NB patients with multiple skeletal metastases at the initial diagnosis.The amplification of MYCN and the viscerocranium metastasis are the poor prognostic factors for HR-NB patients with skeletal metastases.
ABSTRACT
Objective: To explore the risk factors for syncope in children with severe idiopathic pulmonary arterial hypertension (IPAH). Methods: Forty-four patients (age<18 years) with IPAH admitted to the Department of Pediatric Cardiology, Beijing Anzhen Hospital between May 2011 and October 2021 were retrospectively included. Patients were devided into syncope group and non-syncope group. Clinical manifestation and hemodynamic parameters including echocardiography, blood tests, right heart catheterization and acute pulmonary vascular expansion test were compared between two groups. Comparisons between groups were performed with unpaired Student t test, or Mann-Whitney U test or chi-square test. Logistic regression was used to calculate the odds ratio (OR) for parameters with statistically significant differences between groups and analyze the statistical correlation. Results: Among the 44 patients, 16 were males, the onset age was (7.2±3.9) years. Twenty-four (55%) children presented with 1 to 11 times of episodes of syncope, and 18 cases of whom induced by physical activity. Syncope group had a larger proportion of New York Heart Association (NYHA) heart function class Ⅲ-Ⅳ (67% (16/24) vs. 25% (5/20), χ2=7.59, P=0.006), higher brain natriuretic peptide (BNP) value ((251±39) vs. (61±40) pg/L, t=-2.18, P=0.035), higher pulmonary-to-aorta diameter ratio (1.6±0.4 vs. 1.4±0.2, t=-2.25, P=0.030) and larger pulmonary vascular resistance index ((22±11) vs. (16±7) WU/m2, t=-2.13, P=0.039) compared with non-syncope group. The proportion of patent foramen ovale (4% (1/24) vs. 45% (9/20), χ2=10.36, P=0.001), left ventricular ejection fraction (LVEF) ((68±5)% vs. (72±8)%, t=2.23, P=0.031) and the positive rate of acute pulmonary vascular expansion test (8% (2/24) vs. 35% (7/20), χ2=4.77, P=0.029) of syncope group were significantly lower than those of non-syncope group. Multiple Logistic regression analysis showed that NYHA heart function Ⅲ-Ⅳ (OR=6.787, 95%CI 1.445-31.880), pulmonary vascular resistance index (OR=1.247, 95%CI 1.020-1.525) and BNP (OR=1.036, 95%CI 1.007-1.066) were independent risk factors for syncope. The patent foramen ovale (OR=0.010, 95%CI 0.000-0.586) was a protective factor for syncope. Conclusions: NYHA cardiac function grade, pulmonary vascular resistance index and BNP are independent risk factors for syncope. Patent foramen ovale is a protective factor for syncope. Exercise is the main inducement of syncope in children with IPAH.

Objective:To compare the clinical efficacy and complications of intra-arterial chemotherapy (IAC) and intravenous chemotherapy (IVC) for unilateral advanced retinoblastoma (RB).Methods:A retrospective clinical study. From January 2020 to January 2021, 40 patients (40 eyes) unilateral group cT2 RB patients diagnosed at Baoding Children’s Hospital and Beijing Children’s Hospital were recruited in this study. There were 22 males (22 eyes) and 18 females (18 eyes). All were monocular. All the patients were assigned to two groups according to different treatment modalities they received: IVC group and IAC group. There were 26 eyes and 14 eyes, respectively. When the tumor invades the optic nerve, choroid, sclera, anterior chamber and iris, enucleation was performed. The globe salvage rate, tumor extraocular metastasis rate, solid tumor control rate, treatment-related complications and pathological high-risk factors after enucleation were observed. The globe salvage rate and solid tumor control rate were compared between the groups by chi square test.Results:The globe salvage rate of IAC group and IVC group were 88.5% (23/26) and 50.0% (7/14), respectively. Solid tumor control of IAC group and IVC group were 84.6% (22/26) and 42.9% (6/14), respectively. There were statistically significant differences in globe salvage rate and solid tumor control between the two groups ( χ 2=7.18, 7.56; P<0.05). Compared with IVC group, IAC group had less systemic complications, mild ocular and periocular side effects. Among 26 cases in IAC group and 14 cases in IVC group, 3 and 7 cases underwent enucleation respectively. The results of pathological examination showed that there were 2 cases and 3 cases with pathological high-risk factors in the two groups, respectively. During the follow-up period, 2 cases in IAC group had extraocular metastasis, there was no extraocular metastasis in IVC group. Conclusion:Compared with IVC, IAC has the advantages of high tumor control rate, high globe salvage rate, less and mild complications, however, there is still tumor recurrence.
ABSTRACT
Objective:To observe and analyze the clinical characteristics of children who died of intraocular retinoblastoma (RB).Methods:A retrospective clinical study. Fourteen children (23 eyes) with intraocular RB who died after receiving treatment in Beijing Children's Hospital from 2009 to 2017 were included in the study. Among the children, there were 7 males (10 eyes) and 7 females (13 eyes); 5 had unilateral and 9 had bilateral tumor. Age were 17.2±15.5 months. All children underwent RetCam examination. RB was staged according to the international intraocular RB classify. Among the 23 eyes, 1 eye was in stage B, 2 eyes were in stage C, 12 eyes in stage D, and 8 eyes in stage E. Treatment methods included a systemic (vincristine, etoposide and carboplatin) chemotherapy (VEC chemotherapy), enucleation surgery, and vitrectomy. The basic conditions including age, time of diagnosis, pathological diagnosis, treatment and main causes of death were retrospectively analyzed.Results:Among the 14 cases, the first symptom was leukemia in 12 cases, red eye in 1 case, and squintin in 1 case. Systemic VEC chemotherapy was used for 1-6 courses of treatment; 5 cases were enucleated, 3 cases underwent histopathological examination; 3 cases were treated with vitrectomy. Among the 3 cases who underwent histopathological examination, the sclera and optic nerve, optic nerve and optic disc were invasted respectively. Seven patients died of tumor metastasis and/or intracranial lesions (50.0%, 7/14); the median survival time was 19 months. Four patients died of treatment (28.6%, 4/14), including 3 patients died of chemotherapy-related side effects, and 1 died of organ failure after enucleation surgery (7.1%); the median survival time was 3.5 months. Early abandonment of treatment died in 3 cases (21.4%, 3/14); the median survival time was 15 months.Conclusion:Intracranial metastasis is the main cause of death in children with intraocular RB.
ABSTRACT
Objective:To summarize the clinical features of neuroblastoma (NB) with bone metastasis in infants and the prognostic factors.Methods:A retrospective analysis was performed on 32 patients aged ≤12 months who were enrolled in Beijing Children′s Hospital, Capital Medical University from January 2010 to December 2019 and had imaging findings suggesting signs of distant bone metastasis.The control group was included NB children, aged ≤12 months, who were admitted to Beijing Children′s Hospital, Capital Medical University during the same period, without signs of distant bone destruction.The clinical manifestations and auxiliary examinations of infants with bone metastasis were summarized, and the efficacy evaluation and survival analysis of infants with regular treatment and follow-up were conducted until December 31, 2020. Kaplan- Meier survival analysis was used for prognostic analysis, and Log Rank test was used for univariate prognostic analysis. Results:There were 32 NB infants with bone metastases, involving 12 males (37.5%) and 20 females (62.5%), accounting for 16.0% (32/200 cases) of infants diagnosed with NB du-ring the same period.The median age of onset was 9 (4.5-12.0) months.The main primary site included the retroperitoneal and adrenal region in 24 cases(75.0%) and mediastinum in 3 cases (9.4%). Among the 32 cases, 14 cases (43.8%) had simple bone metastasis, 19 cases (59.4%) had distant lymph nodes, 18 cases (56.3%) had bone marrow, and 3 cases (9.4%) had intracranial and meningeal metastasis.Bone metastasis mainly occurred in the skull, with 11 cases of single bone metastases and the remaining with 2 or more bone metastases.Compared with 168 NB infants without bone metastasis, the prognosis of those with bone metastasis was significantly worse [3-year overall survival(OS) rate 97.6% vs.82.7%, P=0.001]. Univariate analysis showed that the prognosis of NB children with bone marrow metastasis, meningeal and intracranial metastasis, MYCN gene amplification, and high-risk group was poor (all P<0.05). Two patients returned to the local hospital for treatment after diagnosis.A total of 30 children were recruited for efficacy evaluation and prognostic analysis.Twenty-nine children underwent surgery, of which 6 cases received surgery before chemotherapy and 23 cases received surgery after chemotherapy.One case received chemotherapy only.The mean course of chemotherapy was 6.2 (4-13) times.One case was treated with radiotherapy, 1 case was treated with Metaiodobenzylguanidine (MIBG) therapy, and 1 case was treated with stem cell transplantation.A total of 18 cases (62.1%) event-free survived, and 12 cases (40.0%) had a mean event at 7 (1.5-32.0) months.Among them, 7 cases survived and 5 cases died (16.7%). The expected 3-year event-free survival rate and OS rate were 57.1% and 82.7%, respectively. Conclusions:The most common sites of infant NB metastasis are bone and bone marrow, and the most common sites of bone metastasis are skull.Infants with bone metastasis had a worse prognosis than those without bone metastasis, and infants with bone and bone marrow metastasis had a worse prognosis than infants with single bone metastasis.
ABSTRACT
To analyze the clinical characteristics, treatment and prognosis of mediastinal germ cell tumors (GCTs) with concurrent hematologic malignancy (HM). The clinical features, treatment and prognosis of 3 cases of HM associated with mediastinal GCTs treated in the Department of Medical Oncology, Beijing Children′s Hospital from November 2014 to September 2018 were retrospectively analyzed.Meanwhile, relevant cases were searched in the PubMed and Wanfang database from their establishment to December 2019.Three male cases of HM associated with mediastinal GCTs aged from 12 to 16 years.The pathogenesis of mediastinal masses suggested teratoma or yolk sac tumor.All of them were treated with surgery and chemotherapy.Acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) was diagnosed respectively at 5 months, 9 months and 31 months after initial GCTs in the 3 cases.Two patients died and 1 child survived at the last follow-up.A total of 135 cases of concurrent GCTs and HM (or leukemia) were reviewed in online databases, involving 127 cases (94.1%) with the mediastinal GCTs associated with HM and 8 cases(5.9%) with GCTs related HM from another original sites.One hundred and twenty-six cases (99.2%) were male and the median age of GCTs diagnosis was 22 (10-48) years.Fifty-three cases (41.7%) were teratoma and 94 cases (74.0%) were GCTs containing teratoma with or without yolk sac tumor.Among the types of HM, 72 cases (56.7%) were AML and 31 cases (24.4%) were AML-M7.The median interval between GCTs and HM was 3 (0-122) months.Forty-six cases (36.2%) presented 2 malignancies simultaneously.HM were diagnosed within 12 months of GCTs in 85 cases (66.9%). The survival data were known in 107 cases, involving 94 (87.9%) deaths and 13 (12.1%) survivors.The median survival time after diagnosis of HM was 2 (0-48) months.The tendency of HM must be highly concerned in adolescent male patients with primary mediastinal GCTs, especially those with yolk sac tumor or teratoma.Their prognoses are very poor.Allogeneic hematopoietic stem cell transplantation is an alternative treatment.
ABSTRACT
Objective:To analyze the clinical characteristics and prognosis of infants with rhabdomyosarcoma (RMS), thus enhancing the understanding of this disease.Methods:Clinical data of all RMS patients younger than 12 months treated in the Hematology Oncology Center, Beijing Children′s Hospital, Capital Medical University from May 2006 to June 2019 were retrospectively analyzed, including the age, gender, histological type, tumor primary site, tumor size, and the prognosis.Patients were followed up until December 31, 2019.The 3-year event free survival (EFS) rate of children was performed by plotting the Kaplan-Meier survival curves.Results:A total of 15 RMS children younger than 12 months were enrolled, accounting for 4.9% of all RMS cases in the same period, including 6 males and 9 females.The median age at diagnosis was 7.0 months (3.0-11.5 months). Classified by the primary site, 40.0% (6 cases) located in the head and neck, followed by 26.7% (4 cases) located in the limbs, 26.7% (4 cases) located in other parts, and 6.7% (1 case) located in the urogenital system.Embryonal RMS, alveolar RMS and spindle cell RMS accounted for 46.6% (7 cases), 26.7% (4 cases), and 26.7% (4 cases), respectively.Ten cases (66.7%) were stage Intergroup Rhabdomyosarcoma Study (IRS)-Ⅲ and 1 case (6.7%) was in stage Ⅳ.There were 10 cases (66.6%) in the middle-risk group, 4 cases (26.7%) in the low-risk group, and 1 case (6.7%) in the high-risk group.Two cases had a larger than 5 cm primary tumor; lymph node involvement was confirmed in 3 cases, and pulmonary metastasis occurred in 1 case at the time of diagnosis.All children were treated with chemotherapy, and 13 cases received postoperative chemotherapy and 1 case received preoperative chemotherapy.One case were not operated.Only 3 children underwent radiotherapy, including 1 case underwent particle implantation and 2 cases received external radiotherapy.Among the 15 children with RMS, 5 cases had relapse and disease progression with the 3-year EFS rate of (59.1±14.5)%, and 2 died with the 3-year overall survival rate of (80.8±12.6)%.Conclusions:The median age of diagnosis of RMS in single-center infants is 7 months.Head and neck are the most common primary sites of RMS.Nearly 50% of the children have the primary site of RMS with poor prognosis.More than a quarter of the pathological subtypes are the spindle cell type.Local treatment significantly influences the local progression or recurrence of RMS.
ABSTRACT
Objective:To explore the clinical significance of the MYCN gene, PHOX2B gene and plasma cell-free DNA (cfDNA) in risk stratification and predicting the prognosis of high-risk neuroblastoma (NB). Methods:This was a prospective study involving 94 high-risk NB children admitted to Beijing Children′s Hospital, Capital Medical University from August 2017 to December 2018.Relative levels of MYCN and PHOX2B and cfDNA at diagnosis, and 4 and 6 cycles of chemotherapy were detected, and their differences were compared by the Chi- square test.Kaplan-Meier survival analysis was performed to explore their prognostic potential in high-risk NB. Results:Among the 94 high-risk NB children, 14 cases (14.9%) had MYCN amplification, 76 cases (80.8%) had positive expression of PHOX2B and 56 cases (59.6%) had cfDNA level higher than 100 μg/L.The proportion of high lactate dehydrogenase (LDH, ≥1 500 U/L) level in the MYCN gene amplification group (6/14 cases) was higher than that in the normal group (9/80 cases) ( P=0.009). The proportion of multi-site metastasis (54/76 cases) and high neuron specific enolase (NSE) level (NSE≥370 μg/L, 37/76 cases) in PHOX2B positive group were significantly higher than those in the negative group (5/14 cases, 2/14 cases) ( P=0.015, 0.020). The proportion of high LDH and high NSE in high cfDNA concentration (≥229.6 μg/L)group (13/37 cases, 28/37 cases) were significantly higher than those in low cfDNA concentration group (2/48 cases, 10/48 cases) (all P<0.001). With the decreased tumor burden during the treatment, the copy number of PHOX2B gene and cfDNA level were significantly lower than those at the initial diagnosis [0 (0-719.6) copies vs.1 723.5 (0-186 000.0) copies; 19.0 (1.1-225.5) μg/L vs.200.6 (8.0-5 247.4) μg/L, all P<0.001]. The 2-year event-free survival (EFS) rate of the MYCN gene amplification group was significantly lower than that of the normal group[(33.3±13.1)% vs.(58.5±7.1)%, P=0.020]. The 2-year EFS rate of PHOX2B positive group was significantly lower than that of the negative group[(47.9±7.1)% vs.(79.1±11.1)%, P=0.043]. EFS rate in high cfDNA concentration group was significantly lower than that in cfDNA low concentration group[(38.6±9.8)% vs.( 71.7±8.2)%, P=0.001]. After 6 cycles of chemotherapy, EFS rate in the PHOX2B positive group was significantly lower than that in the negative group [(16.7±14.4)% vs.( 60.6±6.6)%, P=0.014]; which was significantly lower in the Metaiodobenzylguanidine (MIBG) positive group than that of the negative group[(35.2±11.7)% vs.(65.8±7.1)%, P=0.037]. The MYCN gene and cfDNA concentration were not correlated with the prognosis of high-risk NB.Survival analysis of the combination of PHOX2B and MYCN gene ( PHOX2B+ /MIBG + , PHOX2B+ or MIBG + , PHOX2B-/MIBG -) showed a significant difference in the survival among three groups[0 vs.(53.6±1.2)% vs.(65.5±7.4)%, P=0.003]. Conclusions:The MYCN and PHOX2B gene and cfDNA concentration are of significance in risk stratification and predicting the prognosis of high-risk NB.Compared with the MYCN gene and cfDNA concentration, the PHOX2B gene is more suitable for monitoring the curative effect of chemotherapy on high-risk NB.A combined analysis of PHOX2B gene and MIBG before treatment can be more accurate in evaluating the treatment effect and residual lesions.
ABSTRACT
Objective:Pulmonary annulus index is used to predict the application value of transannular patch in children with tetralogy of Fallot.Methods:A retrospective analysis of 130 patients with pediatric heart disease diagnosis of TOF and undergoing TOF repair in Beijing Anzhen Hospital affiliated to Capital Medical University from December 2018 to December 2019, 112 cases were included in this study, 18 cases were excluded. They were divided into TAP group and no TAP group, related values of pulmonary annulus and aortic annulus were measured. The pulmonary annulus index, the pulmonary annulus Z-score and main pulmonary artery Z-score were calculated to do statistically analyze.Results:A total of 112 patients, average age(22.87±12.21) months; 66 males and 46 females; weight( 9.94±4.08)kg; 3 cases died, 1 case died of sepsis caused by pulmonary infection, 1 case died of low cardiac output syndrome, and 1 case died of multiple organ failure. 62 cases(55.8%) did not transannular patch, 50 cases(44.2%) transannular patch. The pulmonary annulus Z-score, main pulmonary artery Z-score and PAI in TAP group were smaller than those in no TAP group( P<0.05). Receiver operator curves( ROC) analysis showed that the cut-off value of PAI at 0.53 AUC was 0.85, the sensitivity was 75%, the specificity was 80%; the cutoff value of pulmonary annulus at -1.98 AUC was 0.88, the sensitivity was 80%, the specificity was 71%; the cutoff value of main pulmonary artery at -2.12 AUC was 0.87, the sensitivity was 77%, and the specificity was 87%. When the critical value of PAI(>0.53) and main pulmonary artery Z-score(>2.12), 88.2% of the children could avoid TAP, and 94% of the children could avoid TAP when the critical value of pulmonary annulus Z-score(> -1.91) and main pulmonary artery Z-score(>-2.12) were combined. Conclusion:The predictive effect of pulmonary annulus index as a simple and effective predictor of TAP in TOF radical operation is the same as that of pulmonary annulus Z-score. Combining either with main pulmonary artery Z-score was the most accurate method of prediction.
ABSTRACT
Objective:To investigate the influence of different types of wound dressings on red light transmittance.Methods:A treatment environment for wounds exposed to red light was simulated.Red light transmittance of four types of 19 dressings commonly used in clinic were detected respectively and compared.The transmittance was calculated as the ratio of the intensity of the red light through the dressing to the intensity of the injected red light.Results:The red light transmittance for each dressing was the following: (1)Cotton gauze and pad: 29.4% for one piece of coarse gauze, 10.5% for one cotton pad; (2)Oil dressings: 73.0%~79.1% for light-color oil dressings, 41.7% for dark-color oil dressings-Atrauman ?; (3)Hydrocolloid dressings: 87.8%~90.2%; (4)Foams: 74.7% for light-color ultra-thin foam-Mepilex ? sheet, 0.8% for black-color thicker foam dressings-Mepilex ? Ag dressing, and 20.5%-54.2% for the other foam dressings. Conclusions:The red light transmittance of hydrocolloid dressing, light-colored oil gauze dressing and light-colored ultra-thin foam dressing is higher, with less red light-blocking effect, and the dark-color or thicker dressings had more blocking effect, which showed different therapeutic effect on wound.Gauze and cotton pad have great blocking influence on red light transmittance, and are not suitable for temporary covering of wound during red light treatment.Hence, the effect of wound dressing on red light transmittance should be taken into account when the wound is treated with red light.
ABSTRACT
Objective:To summarize the clinical characteristics of single-center children with low and intermediate-risk neuroblastoma (NB), report the long-term follow-up results of the growth and survival quality, and provide a basis for further clinical research.Methods:Clinical characteristics, including the sex, age, stage, risk of disease, and metastatic site of 370 newly treated children with low and intermediate-risk NB admitted to Hematology Oncology Center, Beijing Children′s Hospital from March 2007 to June 2019 were retrospectively analyzed.Kaplan-Meier method was used for survival analysis.WHO Anthro Plus was used for calculating Z score.Results:A total of 370 eligible children with low and intermediate-risk NB were included, with the mean age at onset of 16.8 months (1-191 months). Among them, 148 cases (40%) were younger than 12 months old.Mediastinal region was the most common primary site of NB (47.8%, 177 cases), followed by retroperitoneum/adrenal gland (41.4%, 153 cases). The median follow-up time of 370 patients was 31 months (0.3-157.0 months), the 5-years event free survival (EFS) and 5-year overall survival (OS) were 86.2% and 96.9%, respectively.Thirty-seven cases had growth and deve-lopment problems, of which 22 cases had stunted growth, 6 cases had low body mass, 9 cases had wasting, and 7.3%(27/370 cases) had scoliosis.5.5% of them had heart damage and 5.0%(18/357 cases) had kidney damage, involving 12 cases related to the primary tumor and 6 cases were surgically related.30.2%(95/315 cases) of them had hair changed after chemotherapy, and curly hair was the most common change.Compared with before treatment, 14.9% of the children had a personality change, with an impatient being the most common.Conclusions:The 5-year overall survival rate of the single-center large sample of low and intermediate-risk NB was high, mediastinal was the most common primary site of tumor, and the long-term quality of life is good, but there were still treatment-related side effects, and further clinical monitoring and long-term follow-up were needed.
ABSTRACT
Objective:To summarize the causes of death and severe complication in the early diagnosis of children with neuroblastoma (NB), and to analyze the relative factors of early death of children with NB, so as to raise awareness and reduce early mortality by early detection and early intervention.Methods:Patients with newly diagnosed NB in the Hematology Oncology Center of Beijing Children′s Hospital from April 2007 to December 2017 were included consecutively, and those died within 1 month after diagnosis were retrospectively analyzed.The general data of patients, immediate causes of death, complications, time elapsed between death and diagnosis, whether to receive chemotherapy and other information were collected.Results:A total of 654 cases were included for diagnosis, treatment and follow-up, 31 cases of which died in early stage, accounting for 4.7% of the total.The major complication were pulmonary infection in 18 cases (58.1%) and bone marrow suppression after chemotherapy in 17 cases (54.8%), tumor rupture hemorrhage in 16 cases (51.6%), multiple organ failure in 8 cases (25.8%). Risk factor analysis of the 31 early death cases with NB was conducted.Single factor analysis: there were statistical differences between early death group and non-early death group in risk grouping ( P=0.006 6), bone marrow invasion ( P=0.020 7), site of primary tumor ( P=0.016 7), age ( P=0.003 3), lactate dehydrogenase (LDH) level ( P<0.000 1), neuron-specific enolase (NSE) level ( P<0.000 1), serum ferritin level ( P=0.016 0), D dimer level ( P<0.000 1), fibrinogen level ( P=0.002 7), diameter of tumor ( P<0.000 1), hemoglobin ( P<0.000 1), platelet level ( P<0.000 1), serum albumin level ( P<0.000 1). Multiple-factor analysis: age younger than 30 months, OR=2.824 (95% CI: 1.084-7.359), LDH level greater than 1 004 IU/L, OR=6.991 (95% CI: 2.135-22.887), albumin level less than 36 g/L, OR= 65.237 (95% CI: 2.024-13.545), hemoglobin level less than 92 g/L, OR=5.358 (95% CI: 2.024-13.545), platelet level less than 192×10 9/L, OR=3.554 (95% CI: 1.267-9.965). Conclusions:Strengthening vital signs detection after admission, identifying severe life-threatening complications such as rupture of tumors as early as possible, implementing symptomatic interventions such as appropriate sedation and active transfusion of blood products as early as possible after invasive operation, and transferring to intensive care unit for respiratory support when necessary are important means to avoid early death.
ABSTRACT
Objective:To summarize the clinical characteristics, treatment response and long-term postoperative complications in children with neuroblastoma (NB) in the pelvic and sacral regions as the primary site.Methods:The clinical characteristics of 16 NB children (8 males and 8 females) with primary pelvic and sacral admitted to the Department of Hematology Oncology Center in Beijing Children′s Hospital, Capital Medical University from March 2007 to June 2019 were analyzed retrospectively with respect to the age at first diagnosis, primary tumor site, tumor size, clinical stage, risk grouping, and other clinical characteristics.The clinical characteristics of the patients who were followed up for regular treatment were analyzed, and the postoperative complications of the patients were summarized, and the Kaplan-Meier method was used for survival analysis.Results:The median age at diagnosis of these 16 children was 23.0 months (5.7-102.0 months), of which 6 cases (37.5%) were younger than 12 months old.All these children received chemotherapy, with a median of 6 (1-8) courses of chemotherapy.Fifteen children received surgical resection of the pelvic tumor, with complete resection in 12 cases (80%). The surgical approach was mainly transabdominal (86.7%, 13/16 cases). The median follow-up time of these children was 33.5 (8-136) months.The patella was absent in 3 patients (18.8%) after the operation, and no permanent neurological damage occurred in all patients.Five-year overall survival (OS) rate was 100%.Conclusions:A single-center summary showed a high survival rate for NB patients in the pelvic and sacral regions.Complete tumor resections combined with chemotherapy could be effective measures and rare cases occurred permanent postoperative neurological complications.
ABSTRACT
Objective:To evaluate the clinical efficacy of Buyang-Huanwu Decoction combined with modified Tingli-Dazao-Xiefei Decoction on the basis of conventional western medicine therapy in the treatment of chronic heart failure (CHF) with syndrome of qi deficiency and blood stasis. Methods:Seventy patients who met the inclusion criteria from November 2017 to November 2019 in Shijingshan District Hospital of Traditional Chinese Medicine were randomly divided into two groups, 35 in each group. The control group was treated with western medicine for chronic heart failure, and the treatment group was treated with Buyang-Huanwu Decoction combined with Tingli-Dazao-Xiefei Decoction on the basis of the control group. Both groups were treated for 2 weeks. The TCM syndrome scores were observed and compared before and after treatment. Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to evaluate the quality of life of patients. Lee’s Heart Failure Score was used to evaluate the severity of symptoms. The N-terminal pro-B type natriuretic peptide(NT-proBNP) was detected by ELISA. The adverse reactions during treatment were observed and the clinical efficacy was evaluated. Results:The total effective rate was 91.4% (32/35) in the treatment group and 77.1 % (27/35) in the control group, and the difference was statistically significant ( χ2=7.050, P=0.014). After treatment, the serum NT-proBNP in the treatment group [(1 725.3 ± 1 473.8) ng/L vs. (2 485.7 ± 2 164.4) ng/L; U=341.200, P=0.031] was significantly lower than that of the control group. The NT-proBNP [(54.3 ± 26.7) % vs. (35.5 ± 19.8)%; U=4.310, P=0.003] was significantly higher than that of the control group. After treatment, the TCM syndrome scores and MLHFQ scores in the treatment group were significantly lower than those in the control group ( t=3.785, 9.925, P=0.031, 0.001). During the treatment, no obvious adverse reactions were observed in both groups. Conclusion:On the basis of standardized treatment of Western medicine, Buyang-Huanwu Decoction and Tingli-Dazao-Xiefei Decoction can improve the clinical efficacy of CHF patients with qi deficiency and blood stasis syndrome, promote the repair of damaged myocardium (reduce NT-proBNP), and improve the quality of life of patients.
ABSTRACT
Toxoplasma gondii infection is widespread worldwide, not only posing a serious threat to human food safety and animal husbandry, but also endangering human health. The selectivity index was employed to measure anti-T. gondii activity. Hederagenin (HE) exhibited potent anti-T. gondii activity and low cytotoxicity. For this reason, HE was selected for in vivo experiments. HE showed 64.8%±13.1% inhibition for peritoneal tachyzoites in mice, higher than spiramycin 56.8%±6.0%. Biochemical parameters such as alanine aminotransferase, aspartate aminotransferase, glutathione, and malondialdehyde, illustrated that HE was a good inhibitor of T. gondii in vivo. This compound was also effective in relieving T. gondii-induced liver damage. Collectively, it was demonstrated that HE had potential as an anti-T. gondii agent.

ABSTRACT
Objective:To explore the clinical characteristics, treatment and prognosis of primary cardiac tumors in infants and children.Methods:The clinical information for 21 patients with primary cardiac tumor in the Department of Pediatric Cardiology, Beijing Anzhen Hospital Affiliated to Capital Medical University from May 2010 to August 2018 were analyzed retrospectively.Their median age was 7 months (gestational age 26 weeks-15 years old, and 6 cases were found in fetal phase) and 10 cases of them were male, 11 cases were girl.The clinical features, treatment methods and prognosis were summarized.Results:Among the 21 patients, 8 cases had an atypical heart murmur, 2 cases with chest tightness and chest pain, 2 cases with congestive heart failure, 1 case with dizziness and amaurosis, 1 case with cerebral artery embolism, 1 case with higher inflammatory index, and 9 cases were asymptomatic.Totally, 13 cases underwent surgical resection.All of them were confirmed as benign tumors, including 4 cases of rhabdomyoma, 3 cases of myxoma, 3 cases of fibroma and 2 cases of inflammatory myofibroblastic tumor (IMT) and 1 case of teratomas.There was no death during perioperative period.Follow-ups were performed from 3 months to 7 years, and 3 cases had recu-rrence (2 cases with myxomas and 1 cases with IMT). There were 8 cases without treatment, of which 7 cases were clinically diagnosed as transverse leiomyoma.During the follow-up, 3 cases disappeared, 1 case became small, 2 cases had no obvious change, and 1 case was lost to follow-up.One case was considered to be malignant tumor, and died within half a year.Conclusions:Primary cardiac tumors in children are mostly benign, especially transverse leiomyoma, and their clinical manifestations are diverse.Pathological examination is the golden standard for diagnosis.Surgical treatment is a radical method for most cardiac tumors, some benign tumors can be treated with drug adjuvant therapy, while the prognosis is poor for malignant cardiac tumor patients.
ABSTRACT
BACKGROUND@#It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011.@*METHODS@#A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided).@*RESULTS@#The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107).@*CONCLUSIONS@#The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly.@*TRIAL REGISTRATION NUMBER@#NCT03620565, https://register.clinicaltrials.gov.

Background/Aims@#Accumulating evidence indicates that L-carnitine (LC) protects against multiorgan damage through its antioxidant properties and preservation of the mitochondria. Little information is available about the effects of LC on renal fibrosis. This study examined whether LC treatment would provide renoprotection in a rat model of unilateral ureteral obstruction (UUO) and in vitro. @*Methods@#Sprague-Dawley rats that underwent UUO were treated daily with LC for 7 or 14 days. The influence of LC on renal injury caused by UUO was evaluated by histopathology, and analysis of gene expression, oxidative stress, mitochondrial function, programmed cell death, and phosphatidylinositol 3-kinase (PI3K)/ AKT/forkhead box protein O 1a (FoxO1a) signaling. In addition, H2O2-exposed human kidney cells (HK-2) were treated with LC. @*Results@#LC treatment inhibited expression of proinflammatory and profibrotic cytokines, and was followed by a significant attenuation of tubulointerstitial inflammation and fibrosis. The increased oxidative stress caused by UUO was associated with mitochondrial dysfunction and excessive apoptosis and autophagy via PI3K/AKT/FoxO1a-dependent signaling, and this was abrogated by administration of LC. In H2O2-exposed HK-2 cells, LC decreased intracellular production of reactive oxygen species, and suppressed expression of profibrotic cytokines and reduced the number of apoptotic cells. @*Conclusions@#LC protects against the progression of tubulointerstitial fibrosis in an obstructed kidney.
