Research progress of anti-acute marrow leukemia drugs by targeting FLT3 / 药学学报

Acute myeloid leukemia (AML) is a genetic heterogeneous disease in which primordial and juvenile myeloid cells proliferate or accumulate abnormally in bone marrow, peripheral blood and other tissues, resulting in damage to normal hematopoietic function. Studies have shown that about 30% of AML patients have FMS-like tyrosine kinase 3 (FLT3), FLT3 abnormal regulation is closely related to the occurrence and development of AML. At present, FLT3 has become an important target for developing small molecular targeted drugs. Currently, a variety of FLT3 inhibitors and FLT3 degraders have been developed targeting FLT3, and some compounds have exhibited good anti-AML activity. This article summarizes and sorts out the current mainstream drugs for AML therapeutic targeting FLT3, in order to provide a reference for the development and design of AML drugs.

Analysis of the impact of health management measures for entry personnel on imported Dengue fever in Guangdong Province, 2020-2022 / 中华流行病学杂志

Objective: To explore the impact of health management measures for entry personnel (entry management measures) against COVID-19 on the epidemiological characteristics of imported Dengue fever in Guangdong Province from 2020 to 2022. Methods: Data of imported Dengue fever from January 1, 2016 to August 31, 2022, mosquito density surveillance from 2016 to 2021, and international airline passengers and Dengue fever annual reported cases from 2011 to 2021 in Guangdong were collected. Comparative analysis was conducted to explore changes in the epidemic characteristics of imported Dengue fever before the implementation of entry management measures (from January 1, 2016 to March 20, 2020) and after the implementation (from March 21, 2020 to August 31, 2022). Results: From March 21, 2020, to August 31, 2022, a total of 52 cases of imported Dengue fever cases were reported, with an imported risk intensity of 0.12, which were lower than those before implementation of entry management measures (1 828, 5.29). No significant differences were found in the characteristics of imported cases before and after implementation of entry management measures, including seasonality, sex, age, career, and imported countries (all P>0.05). 59.62% (31/52) of cases were found at the centralized isolation sites and 38.46% (20/52) at the entry ports. However, before implementation of entry management measures, 95.08% (1 738/1 828) of cases were found in hospitals. Among 51 cases who had provided entry dates, 82.35% (42/51) and 98.04% (50/51) of cases were found within seven days and fourteen days after entry, slightly higher than before implementation [(72.69%(362/498) and 97.59% (486/498)]. There was significant difference between the monthly mean values of Aedes mosquito larval density (Bretto index) from 2020 to 2021 and those from 2016 to 2019 (Z=2.83, P=0.005). There is a strong positive correlation between the annual international airline passengers volume in Guangdong from 2011 to 2021 and the annual imported Dengue fever cases (r=0.94, P<0.001), and a positive correlation also existed between the international passenger volume and the annual indigenous Dengue fever cases (r=0.72, P=0.013). Conclusions: In Guangdong, the entry management measures of centralized isolation for fourteen days after entry from abroad had been implemented, and most imported Dengue fever cases were found within fourteen days after entry. The risk of local transmission caused by imported cases has reduced significantly.

Effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant in Guangdong Province / 中华预防医学杂志

Objective: To evaluate the effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant. Methods: A total of 1 403 Omicron-infected patients admitted to 20 designated hospitals in Guangdong Province from January 1 to May 31, 2022, were selected as subjects in this study. A case-control study was conducted to collect the demographic data, underlying disease, vaccination status, last exposure date, gene sequencing of infected strains and clinical outcomes from the China Disease Prevention and Control Information System and Guangdong telemedicine platform. Pneumonia (common, severe and critical) and non-pneumonia (asymptomatic and mild) were selected as the case group and control group. The effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant was analyzed. Results: The median age [M (Q1, Q3)] of the subjects was 36 (27-47) years old, with males accounting for 52.25% (733 cases). The main outcome of the infection was non-pneumonia, accounting for 92.09% (1 292 cases), and the duration [M (Q1, Q3)] of the disease was 18 (14-22) days. There were 134 (9.55%), 39 (2.78%), 403 (28.72%), 437 (31.15%) and 390 (27.80%) cases with no or partial vaccination, within 90 days of primary vaccination, over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination, respectively. Multivariate logistic regression analysis showed that after adjusting for gender, age, underlying disease, and location of the report, compared with those with no or partial vaccination, the risk of developing pneumonia was lower in those with over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination [OR (95%CI) values were 0.52 (0.28-0.98), 0.39 (0.21-0.73) and 0.40 (0.21-0.77), respectively]. Cox proportional hazard regression model analysis showed that after adjusting for gender, age, underlying disease and location of the report, the duration of the disease was shorter in those who received booster vaccinated for more than 90 days compared with that in those who had no or partial vaccination [HR (95%CI): 1.26 (1.03-1.55)]. Conclusion: The inactivated SARS-CoV-2 vaccine affects the clinical outcomes of patients infected with the Omicron variant.

Efficacy and safety of image-guided hypofractionated intensity-modulated radiotherapy combined with contralateral esophageal protection in treatment of unresectable stage Ⅲ non-small cell lung cancer / 肿瘤研究与临床

Objective:To explore the efficacy and adverse reactions of image-guided hypofractionated intensity-modulated radiotherapy (Ig-HypoRT) conbined with contralateral esophageal protection in treatment of patients with unresectable stage Ⅲ non-small cell lung cancer (NSCLC).Methods:The clinical data of 45 patients with unresectable stage Ⅲ NSCLC who were admitted to Xuzhou Cancer Hospital from January 2016 to January 2019 were retrospectively analyzed. Patients received induction chemotherapy with a platinum-based dual-drug combination regimen, followed by Ig-HypoRT with a total dose of tumor of 60-63 Gy/12- 18 times at 3.5-5.0 Gy/time. Contralateral esophagus was delineated as an organ at risk during radiotherapy, limiting V 45 Gy≤1.8 cc and V 55 Gy ≤0.4 cc. Patients' efficacy, survival and the occurrence of adverse reactions were observed. Results:Among 45 patients, there were 9 cases of complete remission, 31 cases of partial remission, 4 cases of stable disease and 1 case of disease progression, and the effective rate was 88.8% (40/45). The median follow-up time was 34 months, 45 patients had a median overall survival (OS) time of 25.0 months (95% CI 21.7-28.8 months), with 1-, 2-, and 3-year OS rates of 78.9%, 56.8% and 47.7%, respectively; the median progression-free survival (PFS) time was 18.5 months (95% CI 15.0-22.0 months), with 1-, 2- and 3-year PFS rates of 59.8%, 32.6% and 18.6%, respectively. The 3-year local recurrence rate was 9% (4/45). The incidence of grade 1-2 radioactive esophagitis was 80% (36/45); the incidence of grade 1-2 chest pain was 20% (9/45). The incidence of grade 3-4 adverse reactions were 13% (6/45), including 7% (3/45) of grade 3 pulmonary atelectasis, 4% (2/45) of grade 3 radioactive pneumonia, and 2% (1/45) of grade 4 hemoptysis. Conclusions:Ig-HypoRT combined with contralateral esophageal protection for unresectable stage Ⅲ NSCLC can improve survival rate and reduce esophageal adverse reactions of patients.

Bardet-Biedl syndrome: a case report / 中华肾脏病杂志

Bardet-Biedl syndrome (BBS) is an autosomal recessive hereditary rare disease with high heterogeneity in clinical phenotypes, which can affect multiple systems, such as six fingers/digits deformity, mental impairment, retinopathy, polycystic kidney, etc, and is easily diagnosed according to a single system disease, resulting in misdiagnosis. The paper reports a case of BBS, diagnosed with "renal cyst, developmental delay, chondrosis, and left foot hexadactylism" at 5 years old, "anemia, renal insufficiency, distal renal tubule poisoning, renal osteodystrophy" at 7 years old. At 10 years old, the patient received hemodialysis treatment for uremia. Cloudy vision appeared in both eyes at 14 years old. Because of the prominent manifestation of kidney damage, the patient was misdiagnosed as "polycystic kidney" for a long time, and other systemic damages were ignored. The result of gene sequencing showed that chromosome 16 NM_031885.5 exon17 had one homozygous nonsense mutation. Therefore, the patient was accurately diagnosed as BBS. This paper is the first report of BBS in Li nationality in China. The relevant literature of BBS were reviewed to strengthen clinicians' understanding of the disease and improve patients' prognosis.

Advances of aerobic glycolysis in renal interstitial fibrosis / 中华肾脏病杂志

Aerobic glycolysis is a metabolic process in which cellular energy production favors the low-efficiency energy-producing glycolytic pathway in the presence of sufficient oxygen, reducing dependence on aerobic respiration, while producing energy rapidly and providing advantages for cell survival and proliferation. In recent years, several studies have shown that aerobic glycolysis is involved in the development of renal interstitial fibrosis (RIF) and involves various cell types such as fibroblasts, endothelial cells, renal tubular epithelial cells, pericytes, and inflammatory cells. Drugs targeting glycolysis may provide new ideas for the prevention and treatment of RIF. This article reviews the research progress of abnormal aerobic glycolysis in different cells and glycolytic intervention drugs in RIF.

The 500th case: pain in both hip joints, headache, and diplopia / 中华内科杂志

A male child, aged 5 years and 3 months, was admitted to the Oncology Department with a history of pain in both hip joints, headache, and diplopia lasting for 40 days. Physical examination did not reveal definitive signs or obvious abnormalities in the nervous system. Imaging studies showed only abnormalities in the craniocerebrum and spinal cord. Routine cerebrospinal fluid (CSF) analysis revealed elevation in the total number of white blood cells, mainly mononuclear cells. Biochemical analysis of CSF showed normal glucose and chloride levels, and increased protein concentrations. The possibility of central nervous system (CNS) infection was initially considered. Subsequently, antibacterial and antiviral therapy was administered; however, this treatment was ineffective. Further examination of CSF through immunophenotyping revealed mature B-cell lymphoma with CNS involvement; there were no neoplastic lesions detected elsewhere in the body. Thus, the patient was diagnosed with primary central nervous system lymphoma (PCNSL). Complete remission was achieved after chemotherapy with the CNCL-2017-mature B-cell lymphoma regimen. Thus far, all chemotherapy cycles have been completed, the patient remains in complete remission, and the follow-up is ongoing. Clinicians should pay close attention to PCNSL in children.

Impact of atrial fibrillation on in-hospital adverse outcomes in elderly patients with acute pulmonary thromboembolism / 中华老年医学杂志

Objective:To analyze the clinical characteristics of elderly acute pulmonary thromboembolism(APE)patients complicated with preexisting atrial fibrillation(AF)and the impact of preexisting AF on in-hospital adverse outcomes in elderly patients with APE.Methods:A retrospective analysis was performed on elderly APE patients with preexisting AF hospitalized in Beijing Anzhen Hospital, Capital Medical University between January 1, 2008 and December 31, 2021.We compared the comorbidities, symptoms, signs, laboratory test results and echocardiographic features, simplified pulmonary embolism severity index(sPESI)scores and adverse in-hospital outcomes between the preexisting AF group and the non-AF group.Logistic regression was used to analyze the risk factors of in-hospital adverse outcomes in elderly patients with APE.Results:A total of 240 patients diagnosed with APE were enrolled.There were 120 patients in the AF group and 120 patients in the non-AF group.For patients in the AF group and the non-AF group, the proportions with chronic heart failure were 38.3%(46/120)and 15.8%(19/120), the proportions with lower extremity deep vein thrombosis(DVT)were 36.7%(44/120)and 65.8%(79/120), the left ventricular ejection fractions(LVEF)were(59±10)% and(62±7)%, and hospital stays were(15±7)and(11±4)days, respectively, and the differences were statistically significant( χ2=15.381, 20.429, t=2.527, -4.710, all P<0.05). The incidences of in-hospital adverse outcomes in the AF group and the non-AF group were 4.2%(5/120)and 3.3%(4/120), respectively, with no significant difference( χ2=0.000, P=1.000). The overall incidence of in-hospital adverse outcomes was 3.8%(9/240). Multivariate Logistic regression analysis showed that elevated lactic acid was an independent risk factor for in-hospital adverse outcomes( OR=2.753, 95% CI: 1.367-5.542, P=0.005). However, AF( OR=2.880, 95% CI: 0.587-14.141, P=0.192)and sPESI score( OR=2.056, 95% CI: 0.904-4.673, P=0.086)were not associated with in-hospital adverse outcomes. Conclusions:Elderly APE patients with preexisting AF have a relatively low incidence of DVT, but a higher proportion have concurrent chronic heart failure and need a longer hospital stay.Elevated lactic acid is an independent risk factor for in-hospital adverse outcomes of elderly APE patients with preexisting AF.However, preexisting AF has no predictive value for in-hospital adverse outcomes in elderly patients with APE.

Prospect on medical treatment of pulmonary mucinous adenocarcinoma / 中国综合临床

Pulmonary mucinous adenocarcinoma is a subtype of lung adenocarcinoma, among which invasive mucinous adenocarcinoma (IMA) is the most common subtype and is easily misdiagnosed as pneumonia. Its etiology and pathogenesis are unclear and may be related to gene mutations and other factors. Due to its relative rarity and few related studies, guidelines do not provide advices on its treatment. KRAS mutations are common in IMA patients, and Sotorasib may be effective against KRAS G12C mutated IMA. NRG1 fusion is considered to be an important driver of IMA, and afatinib may be effective in treating IMA with NRG1 fusion/rearrangement. PD-L1 expression is very low in IMA patients, while B7-H3 expression is high, so B7-H3 may be a potential immunotherapeutic target.

Analysis of incidence and influencing factors of congenital heart disease in perinatal infants in Henan province / 新乡医学院学报

Objective To analyze the incidence, trend and influencing factors of congenital heart disease(CHD) in perinatal infants in Henan province. Methods From 2011 to 2020,1 356 838 perinatal infants born from 28 weeks of pregnancy to 7 days after delivery were selected from 37 national birth defect monitoring points in Henan province as the research subjects, and the incidence of CHD in perinatal infants from different regions, fetal sex and maternal age were compared. The Joinpiont regression model was established to analyze the temporal change trend of the incidence rate of CHD in perinatal infants in Henan province from 2011 to 2020; the annual percentage change (APC) represented the internal trend of each segment, and the average annual percentage change (AAPC) represented the overall change trend. The trend of gap in incidence rate of CHD in different regions, mother's age and perinatal sex was compared by the Joinpiont parallel test. Results From 2011 to 2020,19 004 cases of perinatal infants with CHD were detected in Henan province, with a total incidence of 140.06/10 000; the incidence of CHD in perinatal infants showed an increasing trend year by year (AAPC=43.3% ,P<0.05) From 2011 to 2020, the incidence of CHD in urban perinatal infants in Henan province was significantly higher than that in rural areas, the incidence of CHD in male perinatal infants was significantly higher than that in female perinatal infants，and the incidence of CHD in perinatal infants in older mothers was significantly higher than that in younger mothers (X2=7 259.160,5 415.473,499.520; P<0.05). From 2011 to 2020,the incidence of CHD in perinatal infants in urban and rural areas of Henan province showed an increasing trend year by year (AAPC=42.5% ,44.5% ;P<0.05); the difference between urban and rural areas in the incidence of CHD in perinatal infants was increasing year by year(P<0.05). From 2011 to 2020,the incidence of CHD in male perinatal and famale perinatal infants in Henan province showed an increasing trend year by year(AAPC=44.3%，42.7% ;P<0.05). From 2011 to 2020, the incidence of CHD in perinatal infants of non-elderly and elderly pregnant women in Henan province showed an increasing trend year by year (AAPC=42.9% ,42.7% ;P<0.05).the difference between the elderly arid non-elderly pregnant women in the incidence of CHD In perinatal infants was increasing year by year (P<0.05). Conclusion From 2011 to 2020 ,the incidence of CHD in perinatal infants in Henan province showed an upward trend, and the regional distribution, fetal sex and maternal age were related to the incidence of perinatal CHD.

A multicenter survey of critical neonatal care centers construction and treatment of critically-ill neonates at city- and county-level in Henan Province / 中国新生儿科杂志

Objective:To study the current status of critical neonatal care centers (CNCC) construction and treatment of critically-ill neonates at city- and county-level in Henan Province.Methods:A questionnaire survey was conducted in January 2022 to city- and county-level CNCC in Henan Province. The basic information of CNCC, ward settings, neonatal management in the Department of Obstetrics and the treatment of critically-ill neonates in 2019-2021 were analyzed.Results:A total of 188 questionnaires were sent and 183 (97.3%) eligible questionnaires were analyzed, including 30 from city centers and 153 from county centers. The bed occupancy rate in county centers was significantly lower than city centers (67.3%±24.1% vs. 86.1%±23.2%), and the doctor/bed ratio, doctor/rescue bed ratio and nurse/rescue bed ratio were significantly higher than city centers ( P<0.05). All city centers had set up independent Department of Neonatology and the number is 92.8% (142/153) in county center. For 80.9% (148/183) centers, neonates were managed in the Department of Obstetrics with consultations and referrals to the Department of Pediatrics and 19.1% (35/183) were managed in the Department of Pediatrics/Neonatology. The average number of deliveries and admissions to the Department of Neonatology in both city and county centers decreased year on year during 2019-2021, but the proportion of premature and low/very low birth weight infants treated in these centers increased year on year. During 2019-2021, the top three diseases treated at the city centers were neonatal respiratory distress syndrome, neonatal asphyxia and acute respiratory distress syndrome, while the top three diseases treated at the county centers were neonatal asphyxia, neonatal respiratory distress syndrome and meconium aspiration syndrome. The incidence of sudden infant death syndrome in city and county centers was (10~30)/100,000. Conclusions:The construction of CNCC in Henan Province is facing challenges such as decreased hospital admissions, increased critically-ill neonates, insufficient cooperation between Obstetrics and Pediatrics and waste of resources. Rationally allocated and optimised use of resources to improve the ability to treat critically-ill neonates is warranted.

Effects of recombinant human erythropoietin on cerebral blood flow in preterm infants: arterial spin labeling magnetic resonance imaging evaluation / 中国新生儿科杂志

Objective:To study the effects of recombinant human erythropoietin (rhEPO) on cerebral blood flow (CBF) in preterm infants using arterial spin labeling (ASL) magnetic resonance imaging (MRI).Methods:From September 2021 to June 2022, preterm infants (gestational age ≤32 weeks, birth weight ≤1 500 g) admitted to NICU of our hospital within 24 h after birth were randomly assigned into rhEPO group and control group for this prospective study. The rhEPO group was given rhEPO (500 IU/kg iv, once every other day for 2 weeks) within 72 h after birth plus symptomatic supportive treatment. The control group received same amount of normal saline injection. Both groups received brain MRI, diffusion-weighted imaging and ASL at adjusted gestational age of 35~37 weeks and CBF values of interested areas were measured.Results:A total of 85 infants were enrolled, including 40 in the rhEPO group and 45 in the control group. No significant differences existed in the incidences of periventricular-intraventricular hemorrhage, periventricular leukomalacia, focal white matter injury and extensive white matter injury between the two groups ( P>0.05). The CBF values [ml/(100 g·min)] of frontal cortex [left 15.1±3.9 vs. 17.9±3.1, right 15.9 (12.5, 17.8) vs. 18.1(16.1,20.2)], temporal cortex [left 15.8±4.3 vs. 18.6±3.8, right 16.3(13.2,19.4) vs. 18.1(15.7,19.7)], occipital cortex (left 15.8±6.1 vs. 18.8±3.3, right 16.8±5.5 vs. 19.3±4.8), basal ganglia (left 24.7±7.2 vs. 28.7±6.2, right 26.0±7.9 vs. 29.3±6.4) and thalamus (left 32.7±11.8 vs. 37.9±8.6, right 32.1±11.6 vs. 37.6±10.2) in the rhEPO group were significantly lower than the control group ( P<0.05). No significant differences existed of CBF value at the parietal cortex between the two groups ( P>0.05). Conclusions:Early application of rhEPO can reduce CBF in premature infants, which may be related to the neuro-protective effects of EPO.

Correlation study of imaging characteristics of diffusion tensor imaging and the Yale Global Tic Severity Scale in children with tic disorders / 中华实用儿科临床杂志

Objective:To explore the correlation between imaging features of children with tic disorders and their features assessed by the Yale Global Tic Severity Scale (YGTSS).Methods:A retrospective study.A total of 33 children with tic disorders treated in the Department of Child Rehabilitation, the First Affiliated Hospital of Xinxiang Medical University from January 2022 to March 2023 were included in the tic disorder group, and 10 healthy age-matched children received physical examination during the same period were included in the healthy control group.Under the functional positioning of functional magnetic resonance imaging (fMRI), the active area of children with tic disorders at varying degrees was found.In the region of interest (ROI), localization monitoring and diffusion tensor imaging (DTI) were performed, and the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were recorded.In the same ROI (bilateral thalamus, genu of internal capsule, splenium of corpus callosum, globus pallidus, caudate nucleus) of children in healthy control group, ADC and FA were recorded.Imaging data were compared between groups using the independent sample t test, and their correlation with YGTSS scores was identified by the Pearson correlation analysis. Results:There were significant differences in ADC of the left thalamus (0.869±0.077 vs.0.794±0.083, P=0.022), the right thalamus (0.853±0.055 vs.0.798±0.054, P=0.014), the left caudate nucleus (0.871±0.121 vs.0.787±0.052, P=0.003) and the right caudate nucleus (0.856±0.075 vs.0.788±0.063, P=0.010) between tic disorder group and healthy control group.No significant differences were detected in ADC of the remaining ROI between groups (all P>0.05). There were significant differences in FA of the left thalamus (0.259±0.050 vs.0.344±0.077, P=0.007), the right thalamus (0.265±0.057 vs.0.347±0.095, P=0.026) and the right caudate nucleus (0.168±0.118 vs.0.309±0.181, P=0.041) between tic disorder group and healthy control group.No significant differences were detected in ADC and FA between children with mild and moderate tic disorders (all P>0.05). ADC of the left thalamus and the right caudate nucleus were significantly correlated with YGTSS scores in children with tic disorders ( r=0.407 and 0.372, respectively; all P<0.05). FA of the right thalamus was negatively correlated with YGTSS scores in children with tic disorders ( r=-0.439, P<0.05). Conclusions:ADC of the thalamus and caudate nucleus, and FA of the right thalamus are significantly correlated with YGTSS scores of children with tic disorders.High ADC of the left thalamus and the right caudate nucleus are correlated with high YGTSS scores, indicating a severe symptom of tic disorder in children.A high FA of the right thalamus is correlated with low YGTSS scores, indicating a mild symptom of tic disorder in children.

Analysis of coronary angiographic findings in 117 children with Kawasaki disease and coronary artery lesion / 中华实用儿科临床杂志

Objective:To analyze the coronary angiographic (CAG) characteristics of coronary artery lesion (CAL) in children with Kawasaki disease (KD), and to clarify the necessity of CAG in the diagnosis and treatment of KD combined with CAL in children.Methods:It was a retrospective study to analyze the clinical data, electrocardiogram, echocardiography, time and findings of CAG in children with KD and CAL who underwent CAG in Shanghai Children′s Medical Center of Shanghai Jiao Tong University School of Medicine from January 2013 to August 2022.The distribution, type, severity, and prognosis of CAL were analyzed.Results:A total of 117 children with KD and CAL were included in the analysis.The onset age of KD was from 2 months to 12.8 years old, and the age of performing CAG was from 8 months to 18.1 years old.A total of 234 coronary artery lesions were detected in 117 cases.Among them, CAL in the right coronary artery (RCA), left anterior descending branch (LAD), left main coronary artery and left circumflex artery were detected in 96 branches(41.1%), 78 branches(33.3%), 44 branches(18.8%), and 16 branches(6.8%), respectively.Unilateral coronary artery involvement was detected in 43 cases (36.8%), of which LAD was the dominant; while bilateral involvement was detected in 74 cases (63.2%), among which, LAD and RCA were the most involved arteries.Stratified by the degree of coronary involvement, large coronary aneurysms and severe coronary stenosis were most frequently occurred in the RCA and LAD.In contrast, 10 cases (13.6%), 20 cases (24.3%), 55 cases (45.8%) and 37 cases (67.3%) of intraluminal lesions were found in small, medium and large coronary aneurysms, and stenosis or occlusion, respectively.The incidence of intraluminal lesions tended to be higher in the site of severe lesions.CAG showed stenosis or occlusion in a total of 55 cases, and collateral circulation at varying degrees was found in cases of severe stenosis or occlusion.Conclusions:CAL in children with KD are complex and varied.Although clinical symptoms, routine electrocardiogram and cardiac ultrasound may indicate severe CAL.Their applications are limited by the diagnosis of the type (especially stenosis), degree, and extent of CAL, as well as the detection of extracoronary lesions.CAG is of great significance to identify vascular lesions and guide clinical management of KD combined with CAL in children.

Risk factors of acute kidney injury in children with biliary atresia after liver transplantation / 国际外科学杂志

Objective:To analyze the incidence and risk factors of acute kidney injury in children with biliary atresia after liver transplantation.Methods:The retrospective case-control study was conducted.The clinical data of 115 children with biliary atresia who received liver transplantation for the first time in Beijing Friendship Hospital Affiliated to Capital Medical University from December 2018 to November 2020 were collected.The patients were divided into AKI group ( n=39) and non-AKI group ( n=76) according to the diagnostic criteria of the Kidney Disease Improving Global Outcomes(KDIGO). The differences of clinical indicators between the two groups were compared, and multivariate logistic regression analysis was performed for statistically significant variables ( P<0.05) to further determine the independent risk factors for AKI after liver transplantation. The measurement data of normal distribution were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups.Measurement data with non-normal distribution were represented by M( Q1, Q3), and Mann-Whitney U test was used for comparison between groups.Count data were expressed as cases and percentage, and comparisons between groups were made using Chi-square test or Fisher′s exact test. Results:The incidence of AKI in biliary atresia patients after liver transplantation was 33.9%. Univariate analysis showed that there were statistically significant differences in age ( OR=0.721, 95% CI: 0.553-0.938, P=0.014), preoperative infection ( OR=3.307, 95% CI: 1.294-8.468, P=0.013), PELD score ( OR=1.065, 95% CI: 1.031-1.101, P<0.001), serum creatinine numerical value ( OR=0.745, 95% CI: 0.657-0.858, P<0.001), intraoperative red blood cell transfusion ( OR=1.034, 95% CI: 1.028-1.051, P<0.001) and intraoperative plasma transfusion ( OR=1.055, 95% CI: 1.025-1.086, P=0.002) between the AKI group and the non-AKI group ( P< 0.05). Multivariate logistic regression analysis was performed on the selected indicators by univariate analysis, and the results showed that preoperative infection ( OR=3.763, 95% CI: 1.185-11.945, P=0.025) and low serum creatinine ( OR=0.685, 95% CI: 0.570-0.823, P<0.001), intraoperative red blood cell transfusion ( OR=1.033, 95% CI: 1.015-1.056, P=0.028) was independently associated with postoperative AKI ( P<0.05). The inpatient treatment time in ICU and in hospital between the two groups were statistically significant ( P<0.05). Conclusions:Preoperative infection, low creatinine numerical value and intraoperative red blood cell transfusion are independent risk factors for postoperative AKI in children with biliary atresia. AKI may prolong the time in ICU and in hospital.

Correlation between serum uric acid/albumin ratio and large atherosclerosis stroke, its severity and short-term outcome / 国际脑血管病杂志

Objective:To investigate the correlation between serum uric acid to albumin ratio (UAR) and large-artery atherosclerosis (LAA), its severity and short-term outcome.Methods:Patients with acute ischemic stroke admitted to the Department of Neurology, the Affiliated Hospital of Qingdao University from September 2017 to August 2022 were retrospectively enrolled. They were classified into LAA and non-LAA according to the TOAST etiological criteria. Patients with LAA were further divided into mild stroke group (≤8) and moderate to severe stroke group (>8) according to the National Institutes of Health Stroke Scale score at admission, and good outcome group (≤2) and poor outcome group (>2) according to the modified Rankin Scale score at discharge. Multivariate logistic regression analysis was used to determine the correlation between UAR and LAA, its severity and short-term outcome. The predictive value of UAR for poor outcomes in patients with LAA was evaluated by receiver operating characteristic (ROC) curve. Results:A total of 4 178 patients with acute ischemic stroke were enrolled, including 2 751 males (65.8%), aged 61.95±10.73 years. There were 2 000 (47.9%) patients with LAA, including 1 112 (55.6%) mild stroke and 888 (44.4%) moderate to severe stroke; 813 (40.65%) had good short-term outcomes and 1 187 (59.35%) had poor outcomes. UAR in the LAA group was significantly higher than that in the non-LAA group ( P<0.05). In patients with LAA, the UAR of the moderate to severe stroke group and the short-term poor outcome group were significantly higher than that of the mild stroke group and the short-term good outcome group, respectively (all P<0.05). Multivariate logistic regression analysis showed that the UAR was an independent risk factor for LAA (odds ratio [ OR] 1.043, 95% confidence interval [ CI] 1.016-1.071; P=0.002), its severity ( OR 2.000, 95% CI 1.860-2.151; P<0.001), and short-term poor outcomes ( OR 1.456, 95% CI 1.379-1.537; P<0.001). ROC curve analysis showed that the area under the curve of UAR for predicting short-term poor outcomes in patients with LAA was 0.727 (95% CI 0.704-0.750; P<0.001). The optimal cutoff value was 6.62, and the sensitivity and specificity were 86.6% and 56.7%, respectively. The area under the curve of UAR for predicting short-term poor outcomes in patients with LAA was greater than that predicted solely by uric acid and albumin. Conclusions:UAR is associated with LAA, its severity and poor prognosis, and has higher predictive value for poor outcomes in patients with LAA.

Advances in genetics of dilated cardiomyopathy in children / 国际儿科学杂志

Dilated cardiomyopathy is the myocardial disease characterized by left ventricular or biventricular dilatation accompanied by left ventricular systolic dysfunction, and is the most common type of cardiomyopathy in children.The etiology of dilated cardiomyopathy is complex and diverse, and the corresponding pathogenic gene can be detected in about 40% of patients.The pathogenic genes of dilated cardiomyopathy have a wide range of heterogeneity, encoding cytoskeleton, nuclear membrane, ion channel, sarcomere protein, and other genes that can lead to dilated cardiomyopathy.The technology of gene detection provides an accurate mean for clinics to identify the corresponding mutation sites and types, especially for the mutation types with a high risk of arrhythmia.In the past, the morphological structure of the heart was the main basis for the classification of cardiomyopathy.Genetic testing technology is becoming a tool for the subdivision of cardiomyopathy, providing early diagnosis and treatment for children.This review summarizes the pathogenic genes and corresponding pathogenic mechanisms associated with dilated cardiomyopathy in children, so as to provide help for clinical diagnosis and prevention.

Clinical analysis of 5 children with lymphoma complicated with Pneumocystis jirovecii pneumonia / 白血病·淋巴瘤

Objective:To explore the clinical features of childhood lymphoma complicated with Pneumocystis jirovecii pneumonia (PJP).Methods:The clinical data, diagnosis and treatment of 5 children with lymphoma complicated with PJP admitted to Beijing Children's Hospital from January 2013 to April 2022 were retrospectively analyzed.Results:Among 5 patients, there were 3 males and 2 females, the median onset age was 7 years old; 4 cases were non-Hodgkin lymphoma and 1 case was Hodgkin lymphoma. Fever and cough occurred 5-18 months after chemotherapy; typical mosaic sign could be seen in 2 cases without pneumothorax and pleural effusion as well as other pathogenic infection; all 5 cases had hypoxemia; 4 cases were diagnosed by next-generation sequencing (NGS). The CD4/CD8 ratio decreased in all cases, and the median CD4 positive T-cell was 200/μl. Trimethoprim-sulfamethoxazole (TMP-SMZ) was irregularly used in 3 cases. During the treatment, all cases received mechanical ventilation, TMP-SMZ intravenously dripping combined with caspofungin, glucocorticoid and gamma globulin. All 5 cases of PJP were cured and there was no recurrent infection.Conclusions:Lymphoma children are susceptible to PJP due to immunocompromise caused by chemotherapy, and their condition progresses rapidly. When encountering fever, shortness of breath, severe lung symptoms and mild signs of children, it is necessary to improve the vigilance of PJP. NGS can help diagnosis, and TMP-SMZ should be actively treated and prevented. Early diagnosis and active treatment can achieve a good prognosis.

Effects of transcutaneous electrical acupoint stimulation on the postoperative sleep quality and inflammatory factors in frail elderly patients / 中国针灸

OBJECTIVE@#To observe the effects of transcutaneous acupoint stimulation (TEAS) on sleep quality and inflammatory factor in frail elderly patients undergoing laparoscopic colorectal cancer surgery.@*METHODS@#A total of 100 frail elderly patients undergoing elective laparoscopic colorectal cancer surgery were randomly divided into an observation group and a control group, 50 cases in each one. Patients in the observation group received TEAS, 30 min before surgery until the end of surgery, at 18:00 on the day of surgery and on the 1st, 2nd and 3rd day after surgery (30 min each time). TEAS was delivered at bilateral Neiguan (PC 6), Shenmen (HT 7) and Hegu (LI 4). The disperse-dense wave of 2 Hz/100 Hz was selected, and the maximal stimulation intensity depended on patient's tolerance. The operation procedure in the control group was same as the observation group, but without electric stimulation exerted. The 1st day before surgery and on the 1st, 3rd and 7th day after surgery, the scores of Pittsburgh sleep quality index (PSQI) and Athens insomnia scale (AIS), as well as the serum levels of C reactive protein (CRP) and interleukin-6 (IL-6) were observed in the patients of two groups. At 24 h, 48 h and 72 h after surgery, the score of pain visual analogue scale (VAS) was recorded in the two groups, as well as the pressing times of analgesic pump and the usage of flurbiprofen axetil during analgesic stage. The occurrence of post operative adverse reactions was observed in the patients of two groups.@*RESULTS@#On the 1st and 3rd day after surgery, except the usage of hypnotic drug scores, the scores of each item and the total scores of PSQI, as well as AIS scores were all increased in the two groups compared with those of 1 day before surgery (P<0.05); and the scores in the observation group were lower than those in the control group (P<0.05). On the 7th day after surgery, the scores of each item and the total scores of PSQI, and AIS scores were not different statistically in comparison between the two groups (P>0.05). On the 1st, 3rd and 7th day after surgery, serum levels of CRP and IL-6 were all increased in the patients of two groups when compared with those of 1 day before surgery (P<0.05), serum levels CRP and IL-6 in the patients of the observation group were lower than those of the control group (P<0.05). The VAS scores of 24 h, 48 h and 72 h after surgery, the pressing times of analgesic pump, the frequency and dosage of the remedies were not different statistically between the two groups (P>0.05).@*CONCLUSION@#TEAS can effectively improve sleep quality and reduce inflammatory reaction in frail elderly patients undergoing laparoscopic colorectal cancer surgery.

Brain-computer interface technology for stroke in the past decade: a visualized analysis / 中国康复理论与实践

ObjectiveTo conduct a visualized analysis of the research related to the use of brain-computer interface technology for stroke rehabilitation in the past ten years, and identify and predict the hot spots and hot trends in order to promote the further development of this field. MethodsThe Web of Science Core Collection database was searched for literature related to brain-computer interface technology for stroke rehabilitation from January, 2011 to October, 2022. CiteSpace 5.8.R3 was used to analyze the number of publications, countries, institutions, authors, keywords, co-citations, and grant support. Results and ConclusionA total of 592 papers were included, and the annual number of publications in this field of research showed a rapid growth trend, and the research enthusiasm continued to increase. The United States was in the leading position in this field, with the highest number of cooperative publications and the highest intermediary centrality; China had certain advantages in this field, but still needed to strengthen the exchange and cooperation with other countries/regions. Foreign institutions and authors had formed a network of close cooperative relationships, and formed a high-impact team represented by Niels Birbaumer, Cuntai Guan, Kai Keng Ang, etc.; there were poor cooperative relationships among domestic authors and institutions, and there were geographical restrictions and lack of high-impact academic groups. The keywords "motor imagery" and "recovery" formed ten major clusters and 15 prominent words with high variation rates, showing a trend of diversification in research directions. The study of the efficacy of upper limb motor rehabilitation and central mechanisms has been the hot topics in this field and will continue for some time in the future; the use of lower limb brain-computer interface systems for improving foot drop, gait and balance in stroke patients and the application of multimodal brain-computer interfaces will probably become a hot topic in the future. Finally, the use of brain-computer interface-guided neurofeedback training for cognitive and language rehabilitation in stroke also needs attention.
