Objective:To investigate the clinical characteristics, treatment effect and prognosis of children with nearly diploid neuroblastoma (NB).Methods:A retrospective analysis of the general clinical characteristics (including age, Gender, risk grouping, location of primary tumor, etc.), laboratory test results, treatment and recent prognosis of NB children with nearly diploidy in bone marrow chromosomes by G-banding technology who admitted to Beijing Children′s Hospital, Capital Medical University from January 2015 to December 2018. Kaplan- Meier method was adopted to calculate survival rate.Univariate analysis was performed using Log- Rank test, and multivariate analysis was conducted with Cox regression model. Results:A total of 43 patients, including 27 males and 16 females, with diagnosis were included, with 14 cases in the hypodiploid group and 29 cases in the hyperdiploid group, and the median age was 35.5 months.The 43 children were all in the high-risk group of International Neuroblastoma Staging System(INSS)-Ⅳ.The primary tumors were mainly located in the retroperitoneal adrenal region (83.7%, 36/43 cases). The largest diameter of the tumors was more than 10 cm (53.5%, 23/43 cases), and often accompanied by 2 or more metastases at the time of consultation.In terms of chromosome karyotype and chromosome karyotype of 14 children in the hypodiploid group was 41-45, the most common karyotype was 45 chromosomes[9 cases(64.3%)]. Among 29 children in the hyperdiploid group of the 47 chromosome karyotypes, 11 cases were common (37.9%). Tumor markers were as follows: neuron enolase (NSE) increased in 41 cases children (95.3%) at first diagnosis, and 25 cases (58.1%)> 370 μg/L; 42 cases (97.7%)had lactate dehydrogenase (LDH). The LDH of children in the hypodiploid group was all> 500 U/L, with 1 case was> 10 000 U/L.Nine cases (20.9%) of MYCN gene were detected by fluorescence in situ hybridization (FISH). Treatment and prognosis: the total course of chemotherapy for 43 patients was 1-12, 19(44.2%) patients received autologous stem cell transplantation, 21 patients (46.5%) received postoperative or autologous radiotherapy or metaiodobenzylguanidine treatment, 28 children developed or relapsed with a median duration of 13.8 months, and 15 cases (34.9%) died.The median follow-up time of the 14 children in the hypodiploid group was 14.9 months (2-38 months), 12 cases progressed or relapsed, and 7 died.The median follow-up of 29 children in the hyperdiploid group was 20.0 months (8.1-51.6 months), with 16 patients progressed or relapsed and 8 cases died. Kaplan- Meier survival analysis illustrated that the 3-year projected event free survival (EFS) rate of 43 children was 18.4%, of which 17.1% were in the hypodiploid group and 29.8% in the hyperdiploid group. Conclusions:Preliminary analysis reveals that children with nearly diploid NB are mostly in the stage Ⅳ high-risk group over the age of 18 months, and 2 or more metastases at the time of consultation.The 3-year estimated EFS of 43 children was 18.4%, and the prognosis was worse in the hypodiploid group.

status.Conclusion HPV6 and HPV-16 were the most two popular HPV types in the whole population,while HPV-16 was the most common type in CIN2+ population.HPV-16 seroprevalence increased with severity of cervical intraepithelial neoplasia.

Objective: To explore the clinical efficacy of Xiaoshuan enteric-coated capsule (XSECC) in treating cerebral infarction and its potential mechanism of action. Methods: Patients with acute ischemic stroke (AIS) of the qi deficiency and blood stasis type were randomly assigned to the control and observation groups. They were evaluated using the National Institutes of Health Stroke Scale (NIHSS), Activities of Daily Living (ADL), Hachinskilnchemic Scale (HIS), Barthel Index (BI), clinical efficacy scores, and TCM syndrome scores on days 0, 14, 30, and 90. Furthermore, VEGF and BDNF levels were measured on days 30 and 90. Finally, we analyzed the changes in each scale score and vascular neurological factor in both groups. Results: After 14 days of treatment, the difference values in NIHSS, ADL, and BI were higher, and TCM syndrome and clinical efficacy scores were increased in the observation group compared with those of the control group (all P < .05). After 30 days, the NIHSS, ADL, HIS, and TCM syndrome scores were decreased compared with those of the control group, while BI and clinical efficacy scores were increased (all P < .05). After 90 days, the difference value in ADL was higher, and TCM syndrome score was increased in the observation group compared with that of the control group (P = .047, P = .005, respectively). The levels of VEGF and BDNF were higher in the observation group than in the control group on days 14, 30, and 90 (all P < .05). VEGF and BDNF levels on day 0 were associated with prognosis of patients with AIS; therefore, they have a predictive value for the prognosis of acute cerebral infarction. Conclusions XSECC therapy can improve clinical outcomes in patients with acute and recurrent cerebral infarctions. Its mechanism of action may be associated with the secretion of VEGF and BDNF.

Objective To evaluate the curative effect of compound nutrient assisted phototherapy on neonatal jaundice.Methods Neonatologists at seven hospitals participated in the study.A total of three hundred and twenty full-term newborns with high indirect bilirubin admitted to hospital from September 2017 to January 2018 were selected.One hundred and sixty-six cases in the observation group,and one hundred and fifty-four cases in the control group,all enrolled neonates were given single-sided,conventional intensity phototherapy.Observation group took compound nutrient at the same time.The average gestational age,age,birth weight of two groups before treatment were not significantly different.Serum total biilirubin,indirect bidirubin,liver function (ALT,AST) and phototherapy time were monitored before treatment and 3 days after treatment.Results The serum total bilirubin in the observation group was significantly lower than that of the control group after 3 days of treatment[(196.7 ± 57.2) μmol/L vs (216.5 ± 54.6) μmol/L],(t=3.17,P＜0.01).The indirect bilirubin in the observation group was significantly lower than that of the control group after 3 days of treatment [(176.3 ± 54.3) μmol/L vs (197.2 ± 52.9) μmol/L],(t=3.50,P＜0.01).The time of phototherapy of the children in the observation group was significantly shorter than that of the control group[(19.8 ± 14.4)d vs (22.9 ± 13.3) d],(t =2.00,P ＜ 0.01).Rash,fever,bronze disease,spilled milk,vomiting,abdominal distention,diarrhea,constipation,liver damage etc.were no significant difference the observation group and the control group(P ＞ 0.05).Conclusion Compound nutrients had good efficacy and safety in adjuvant phototherapy for neonatal high indirect bidirubin.

Objective To evaluate the effect of the rehabilitation software based on information-motivation-behavioral skills(IMB)model on meeting the rehabilitation needs, increasing the continuation of rehabilitation and the rehabilitation compliance, improving the outcome of rehabilitation among elderly patients with fracture. Methods Based on the theory of"information-motivation-behavior"and the unity of human- computer interaction as the design concept, the status quo of rehabilitation training and rehabilitation needs of elderly patients with fracture were reviewed. The rehabilitation training test was applied to 30 patients with fracture in orthopedic department of our hospital. 30 patients in the same period were randomly selected as control group. All patients underwent Self-Rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores before and 1 and 3 months after operation. Differences were tested using Student's t test. Results Developed rehabilitation application software based on information module、motivation module and behavior module. The test group using this software for rehabilitation training was compared with the control group. The results showed that there was no significant difference in preoperative SAS and SDS scores between the two groups (t=-0.648,-0.284, P>0.05). At 1 and 3 months after operation, the SAS scores in the test group were (40.05 ± 6.77), (32.01 ±5.86), which were lower than (45.50 ± 11.32), (39.55 ± 5.67) in the control group (t=-4.14,-4.89, P<0.01). The SDS scores in the test group were (42.30 ± 9.86), (33.23 ± 6.56), which were lower than (46.50 ± 10.32), (38.45 ± 7.80) in the control group (t=-3.52,-3.82, P=0.001). Conclusion Rehabilitation software can influence the rehabilitation behavior of elderly fracture patients from information and motivation factors, provide professional guidance and rehabilitation intervention, and promote the implementation of active rehabilitation.

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.

Objective To understand the implementation of the nursing group standards for oxygen inhalation therapy in clinical practice,and to provide a reference for improving the nursing practice of oxygen therapy.Methods A convenience sampling method was used to investigate nurses from 902 hospitals in 24 provinces and municipalities directly under the central government using a self-designed questionnaire from December 15th,2022,to January 14th,2023.The content of questionnaire included whether they had implemented the recommendations of the oxygen therapy standards,the knowledge of safety related to oxygen therapy,and the components of oxygen therapy prescriptions,the indications used for patients receiving oxygen therapy and practice status of oxygen therapy.Results A total of 10481 questionnaires were returned,of which 10447 were valid,with a valid questionnaire recovery rate of 99.68%.63.14%of the nurses indicated that the hospital had organized training on oxygen therapy standards.Only 47.82%of nurses know the correct use of the Venturi mask.41.90%of nurses could indicate the correct indicator of flow adjustment.31.88%of the nurses stated that they will adjust the oxygen flow rate based on the oxygenation status of carbon dioxide storage patients.Only 19.56%of nurses indicated that humidification is applied in oxygen therapy based on the oxygen flow and duration.Conclusion Even though nurses had received training related to oxygen therapy standards,the level of knowledge of oxygen therapy standards was still low;therefore continuous systematic training was needed,and the implementation of the content of oxygen therapy standards needed to be further standardized.Healthcare institutions would focus on organizing systematic training and maintaining the training effect,enhancing infrastructure and providing support for implementation.Recommendation to the nursing administration is to explore how to comprehensively and continuously implementing the oxygen therapy nursing standards with the ultimate goal of providing patients safer and more accurate oxygen therapy.

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.
