Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To explore the effect of ritodrine hydrochloride combined with magnesium sulfate in the treatment of threatened abortion in older patients with a second child and to analyze its possible mechanism of action.Methods From March 2020 to December 2021,100 older second-child patients with threatened abortion at Handan Maternal and Child Health Hospital were selected and divided into control and observation groups using a random number table method,with 50 cases in each group.The control group was treated with magnesium sulfate based on general intervention measures(bed rest,intermittent oxygen inhalation,nutrition intake,and psychological nursing),while the observation group was treated with ritodrine hydrochloride combined with magnesium sulfate based on general inter-vention measures.The treatment effects,immunoregulatory function indicators[serum blocking antibody(BA)and anticardiolipin antibody(ACA)],sex hormone levels[progesterone(P),estradiol(E2),β-human chorionic gonadotropin(β-hCG)]and related cytokines[pregnan-cy-associated plasma protein A(PAPP-A),human leukocyte antigen G(HLA-G),and interleukin-10(IL-10)]before and after treatment,as well as maternal and infant outcomes and adverse reactions were compared.Results The total efficacy rate was higher in the observa-tion group than in the control group(96％vs.80％,P＜0.05).Compared with before treatment,the serum BA-positivity rate significantly increased and the ACA-positivity rate significantly decreased in both groups after treatment(both P＜0.05).However,after treatment the serum BA-positivity rate was higher in the observation group than in the control group,and the ACA-positivity rate was lower than that in the control group(both P＜0.05).Compared with before treatment,the serum P,E2,β-hCG,PAPP-A,HLA-G,and IL-10 levels signifi-cantly increased at the end of treatment and 2 weeks after treatment in both groups.The levels of sex hormones and related cytokines in the observation group were higher than those in the control group at the end of treatment and two weeks after treatment(both P＜0.05).The success rates of pregnancy maintenance,full-term delivery,and natural labor were higher in the observation group than in the control group;however,the incidences of abortion,premature delivery,cesarean section,and adverse neonatal outcomes were lower than those in the control group(all P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P＜0.05).Conclusion The combination of ritodrine hydrochloride and magnesium sulfate has significant therapeutic effects in the treatment of threatened abortion in older women with a second pregnancy.It can improve maternal immune regulation,regulate sex hormone levels and PAPP-A,HLA-G,and IL-10 levels,reduce adverse maternal and fetal outcomes,and does not increase adverse reactions.

OBJECTIVES: To develop a risk prediction model for severe adenovirus pneumonia (AVP) in children, and to explore the appropriate timing for intravenous immunoglobulin (IVIG) therapy for severe AVP. METHODS: Medical data of 1 046 children with AVP were retrospectively analyzed, and a risk prediction model for severe AVP was established using multivariate logistic regression. The model was validated with 102 children with AVP. Then, 75 children aged ≤14 years who were considered at risk of developing severe AVP by the model were prospectively enrolled and divided into three groups (A, B and C) in order of visit, with 25 children in each group. Group A received symptomatic supportive therapy only. With the exception of symptomatic supportive therapy, group B received IVIG treatment at a dose of 1g/(kg·d) for 2 consecutive days, before progressing to severe AVP. With the exception of symptomatic supportive therapy, group C received IVIG treatment at a dose of 1 g/(kg·d) for 2 consecutive days after progressing to severe AVP. Efficacy and related laboratory indicators were compared among the three groups after treatment. RESULTS: Age<18.5 months, underlying diseases, fever duration >6.5 days, hemoglobin level <84.5 g/L, alanine transaminase level >113.5 U/L, and co-infection with bacteria were the six variables that entered into the risk prediction model for severe AVP. The model had an area under the receiver operating characteristic curve of 0.862, sensitivity of 0.878, and specificity of 0.848. The Hosmer-Lemeshow test showed good consistency between the predicted values and the actual observations (P>0.05). After treatment, group B had the shortest fever duration and hospital stay, the lowest hospitalization costs, the highest effective rate of treatment, the lowest incidence of complications, the lowest white blood cell count and interleukin (IL)-1, IL-2, IL-6, IL-8, IL-10 levels, and the highest level of tumor necrosis factor alpha (P<0.05). CONCLUSIONS The risk model for severe AVP established in this study has good value in predicting the development of severe AVP. IVIG therapy before progression to severe AVP is more effective in treating AVP in children.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

OBJECTIVE: To explore the possible risk factors of death in children with acute lymphoblastic leukemia (ALL) after treatment. METHODS: The clinical data of 31 children with newly diagnosed acute lymphoblastic leukemia and dead after treatment in the Hematology Oncology Department of Wuhan children's Hospital from January 1, 2016 to December 31, 2019 were retrospectively analyzed. Univariate factor analysis and multivariate Cox regression analysis were used to analyze the each indexes of ALL children, and the possible risk factors causes of death in ALL children after treatment were analyzed. RESULTS: Among 230 newly diagnosed ALL children, 31 (13.4%) cases were dead. Among them, there were 12 male and 19 female. The mortality rates were 9%(12/133) for male and 19.5%(19/97) for female, which showed a significantly difference（P=0.02）； among the dead ALL children, 6 were less than 1 year old, 23 were 1-10 years old, and 2 was more than 10 years old. The mortality rates in different age groups were 46.1 % (6/13), 11.7%(23/195) and 9%(2/22), respectively, which showed a significantly difference（P=0.00）； the mortality rates of the ALL children in standard risk group, medium risk group and high risk group were 6.7% (4/59), 11.9% (13/10 CONCLUSION The female, less than 1 year old at initial diagnosis, high risk ALL, WBC>50×10

OBJECTIVE: To study the significance of the level of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in serum and bronchoalveolar lavage fluid (BALF), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and Sequential Organ Failure Assessment (SOFA) score in evaluating the conditions and prognosis of children with severe pneumonia. METHODS: A total of 76 children with severe pneumonia who were admitted from August 2017 to October 2019 were enrolled as the severe pneumonia group. According to the treatment outcome, they were divided into a non-response group with 34 children and a response group with 42 children. Ninety-four children with common pneumonia who were admitted during the same period of time were enrolled as the common pneumonia group. One hundred healthy children who underwent physical examination in the outpatient service during the same period of time were enrolled as the control group. The serum level of sTREM-1, APACHE II score, and SOFA score were measured for each group, and the level of sTREM-1 in BALF was measured for children with severe pneumonia. The correlation of the above indices with the severity and prognosis of severe pneumonia in children was analyzed. RESULTS: The severe pneumonia group had significantly higher serum sTREM-1 level, APACHEII score, and SOFA score than the common pneumonia group and the control group (P<0.05). For the children with severe pneumonia, the non-response group had significant increases in the levels of sTREM-1 in serum and BALF and SOFA score on day 7 after admission, while the response group had significant reductions in these indices, and there were significant differences between the two groups (P<0.05). Positive correlation was found between any two of serum sTREM-1, BALF sTREM-1, and SOFA score (P<0.05). APACHE II score was not correlated with serum sTREM-1, BALF sTREM-1, and SOFA score (P>0.05). CONCLUSIONS The level of sTREM-1 in serum and BALF and SOFA score can be used to evaluate the severity and prognosis of severe pneumonia in children.

OBJECTIVE: To study the changes in pulmonary function in infants and young children with Mycoplasma pneumoniae pneumonia (MPP). METHODS: A total of 196 hospitalized children (at age of 0-36 months) who were diagnosed with MPP from January 2014 to June 2018 were enrolled as study subjects. A total of 208 children (at age of 0-36 months) with pneumonia not caused by Mycoplasma pneumoniae infection during the same period of time were enrolled as controls (non-MPP group). A retrospective analysis was performed for their clinical data. The two groups were compared in the pulmonary function on the next day after admission and on the day of discharge. The children with MPP were followed up to observe pulmonary function at weeks 2 and 4 after discharge. RESULTS: Compared with the non-MPP group, the MPP group had significant reductions in the ratio of time to peak tidal expiratory flow to total expiratory time (TPTEF/TE), ratio of volume to peak tidal expiratory flow to total expiratory volume (VPTEF/VE), inspiratory-to-expiratory time ratio, and tidal expiratory flow at 25% remaining expiration on the next day after admission and on the day of discharge (P<0.05). In addition there were significant increases in the ratio of peak tidal expiratory flow to tidal expiratory flow at 25% remaining expiration, respiratory rate, effective airway resistance, and plethysmographic functional residual capacity per kilogram (P<0.05). Compared with the normal reference values of pulmonary function parameters, both groups had reductions in VPTEF/VE and TPTEF/TE on the next day after admission; on the day of discharge, the MPP group still had reductions in VPTEF/VE and TPTEF/TE, while the non-MPP group had normal values. The MPP group had increases in VPTEF/VE and TPTEF/TE from the day of discharge to weeks 2 and 4 after discharge (P<0.05), but TPTEF/TE still did not reach the normal value at week 4 after discharge. CONCLUSIONS Airway obstruction is observed in infants and young children with acute MPP or non-MPP, and the children with MPP have a higher severity of airway obstruction and a longer time for improvement, with a certain degree of airway limitation in the recovery stage.

Objective To compare the efficacy and safety of gefitinib, erlotinib, and afatinib in the first-line treatment of advanced non-small cell lung cancer (NSCLC). Methods PubMed, EMBASE, and The Cochrane Library were searched to identify the relevant literatures published from December 2008 to December 2018. Bayesian network meta-analysis was carried out to rank the three treatments. Results A total of ten eligible studies involving 2275 patients were enrolled. In terms of efficacy, the surface under the cumulative ranking (SUCRA) indicated that erlotinib performed best in progression-free survival(PFS)(0.88), afatinib performed best in objective response rate(ORR)(0.82) and disease control rate(DCR) (0.86), gefitinib performed worst in PFS (0.45), ORR(0.42), and DCR(0.45). For safety, the differences of grade 3 or 4 adverse events rate (OR=0.29,95%CI:0.08-0.98) and discontinuation rate(OR=0.14,95%CI:0.01-0.8) between erlotinib and the platinum-based doublet chemotherapy were statistically significant. The ranking results also supported that erlotinib was the safest. SUCRA results suggested that gefitinib (0.31) had a lower grade 3 or 4 adverse events rate than afatinib (0.57), and the possibility of discontinuation in gefitinib (0.44) was similar to that of afatinib (0.41). Conclusion Erlotinib might be the preferred first-line treatment for advanced NSCLC after weighing and balancing the benefits and risks.

Objective: To explore the menopausal symptoms and quality of life of hormone receptor positive (HR+ ) breast cancer patients at different endocrine therapy time. Methods: The HR+ breast cancer patients who were pathologically confirmed from 2011 to 2017 in the Sichuan Cancer Hospital were divided into three groups according to endocrine therapy time (<12 months, 12~36 months, >36 months) and analyzed by a cross-sectional study. The Menopausal symptoms and quality of life of these patients were measured using the modified Kupperman scale and the functional assessment of cancer therapy-breast cancer (FACT-B) scale. The differences of menopausal symptoms among different time groups and drug groups were analyzed by Chi-square test. The differences of quality of life and the effects of menopausal symptoms on quality of life were tested by covariance and multiple linear regression analyses. Results: The average score of menopausal symptom of 167 patients was 14.5±7.6 and the prevalence rate was 87.4% (146/167). Among all of the menopausal symptoms, the prevalence rate of insomnia was the highest (73.7%, 123/167). Besides insomnia and excitement, hot flashes was more prevalent in selective estrogen receptor modulator (SERM) users (64.8%, 79/122) , while osteoarthritis was more prevalent in aromatase inhibitor (AI) users (62.2%, 28/45). The total score of FACT-B of Patients was 104.5±15.5, and the compliance rate was up to 89.8% (150/167). However, the condition of each dimension was different, the compliance rates of social/ family and functional dimension were lowest, which were 73.0% (122/167) and 50.9% (85/167), respectively. The menopausal symptoms of patients at different time groups were 15.0±1.3, 14.0±6.9, 14.5±7.4, respectively, and the total score of FACT-B of patients at different time groups were 102.7±17.8, 105.0±12.9, 105.6±16.7, respectively, without significant differences (both P>0.05). Multiple linear regression analysis showed that menopausal symptoms impaired the quality of life of SERM users during the endocrine therapeutic period. The standardized regression coefficients of three time groups were -0.67, -0.30, -0.50, respectively, with the lowest effect on 12~36 months group. Conclusion HR+ breast cancer patients will have a poor function recovery and social/ family return, who need more attention. Menopausal symptoms are common problems during endocrine therapy, and active measures should be taken to improve patients′ quality of life.
