Objective To investigate the predictive value of serum placental growth factor(PLGF)/soluble fms-like tyrosine kinase-1(sFlt-1),combined with the placental three-dimensional energy Doppler index(3D-PDI)in preeclampsia(PE).Methods From January 2021 to December 2022,120 pregnant women with PE risk factors were selected and followed up until 1 week after delivery.Serum PLGF and sFlt-1 levels were measured at routine prenatal check-ups at 14 to 20 weeks gestation.The PLGF/sFlt-1 ratio was calculated,and placental 3D-PDI was detected by ultrasound,including the vascularization index(VI),blood flow index(FI),and vascularization-blood flow index(VFI).Based on whether PE occurred after 20 weeks of pregnancy,cases were divided into PE(55 cases)and control groups(65 cases).The PE group was further divided into mild PE(35 cases)and severe PE groups(20 cases)based on the severity of the di-sease.The differences in PLGF/sFlt-1 and 3D-PDI between the groups were compared in terms of a statistical analysis of the correlation between PLGF,sFlt-1,and 3D-PDI.The receiver operating characteristic curve(ROC)was plotted,and the predictive value of each index on PE alone or in combination was analyzed.Results The systolic blood pressure(SBP),diastolic blood pressure(DBP),24 h protein-uria level,preterm birth rate,NICU admission rate,and preconception BMI in the PE group were higher than those in the control group(P＜0.05).The two groups had no differences in age,gestational age,pregnancy history,and fertility history(P＞0.05).The serum PLGF/sFlt-1 of the PE group was lower than that of the control group,and the serum PLGF/sFlt-1 of the severe group was lower than that of the mild group(P＜0.05).The 3D-PDI index of the PE group was lower than that of the control group,and the 3D-PDI index of the severe group was lower than that of the mild group(P＜0.05).Pearson's correlation analysis indicated that PLGF and VFI were signifi-cantly positively correlated(P＜0.01),and sFlt-1 was significantly negatively correlated with VFI(P＜0.01).ROC curve analysis showed that PLGF/sFlt-1,VI,FI,and VFI all had predictive value for PE and the value of VI,FI,and VFI jointly predicted PE,and was higher than that of various parameters(AUC = 0.951).Serum PLGF/sFlt-1,VI,FI,and VFI combined predicted the highest value(AUC=0.987).Conclusion In patients with PE,serum PLGF,sFlt-1,and placental VFI are significantly correlated.Serum PLGF/sFlt-1,placenta VI,FI,and VFI are reduced in early pregnancy,and the combined application of the four indicators has the highest efficacy in predicting PE,providing a possible reference for the early clinical screening or prediction of PE.

Objective To apply cone beam CT measurements(CBCT)to analyze the effect of skeletal Class Ⅲ high angle with devia-tion on upper airway morphology and hyoid position.Methods A total of 120 patients with skeletal Class Ⅲ high angle malocclusion who visited our hospital from September 2019 to December 2022 were selected.CBCT was taken in all subjects.According to the degree of mandibular deviation(MD)of the point under the chin from the median sagittal plane,the 120 patients were divided into three groups:non-migratory,mildly migratory,and severely migratory groups,and the volume of the upper airway as well as the position of the hyoid bone of three groups were measured and analyzed respectively.Results There was no significant difference in the volume and minimum cross-sectional area of the nasopharyngeal segment,palatopharyngeal segment,and minimum cross-sectional area of the laryngopharyngeal segment.No siginificant difference was found between the position of the hyoid bone(HB)on the Y-axis(Y-HB)and the position of the hyoid bone on the Z-axis(Z-HB)among the three groups(P＞0.05).Compared with the other two groups,the vol-ume and total volume of the nasopharyngeal segment,the laryngopharyngeal segment,and minimum cross-sectional area of the laryngo-pharyngeal segment in the group of severe deviation were significantly reduced(P＜0.05)and X-HB was significantly larger(P＜0.05).Conclusion In patients with skeletal ClassⅢhyperkeratosis with severe deviation,the total volume of the glossopharyngeal segment,laryngopharyngeal segment,and upper airway,as well as the minimum cross-sectional area of the glossopharyngeal segment were smal-ler than those of the othertwo groups.In patients with severe deviation,the position of the hyoid bone(HB)in the X-axis(X-HB)was larger than that of the non-migratory group,indicating that migratory jaws mainly affect the morphology of the lingual-pharyngeal seg-ment as well as the laryngopharyngeal segment of the upper airway;the effect of migratory jaws on the hyoid bone is reflected in the X-HB,indicating that migratory jaws can lead to the deviation of the hyoid bone from the median sagittal plane.

Objective:To analyze the proportion of patients with acute primary angle-closure glaucoma (PACG) after the outbreak of coronavirus disease 2019 (COVID-19) in patients undergoing glaucoma surgery and the factors influencing morbidity.Methods:A cross-sectional study was performed.The cluster sampling method was used to collect 141 glaucoma patients hospitalized for glaucoma surgery after the outbreak of COVID-19 in Xuzhou First People's Hospital from December 16, 2022, to January 16, 2023, and 231 glaucoma patients hospitalized for surgery in the same 1-month period from 2019 to 2020, 2020 to 2021, 2021 to 2022 through the hospital information system.Ninety-two eyes of 92 patients with acute PACG after the outbreak were selected as a study group, and 21 eyes of 21 patients with acute PACG hospitalized during the same 1-month period from 2021 to 2022 were selected as a control group.The proportion of patients with different types of glaucoma during the observation period was analyzed.The proportion of patients with acute PACG and the clinical characteristics of acute PACG were analyzed, including age, sex, visual acuity, intraocular pressure (IOP), and anterior chamber angle status.Epidemiological data such as the use of anti-cold medications, and changes in living habits and moods (including daily water intake and anxiety) of patients after COVID-19 infection were obtained by telephone follow-up.Anxiety levels of patients in the study group were assessed using the Hospital Depression and Anxiety Scale (HADS).The triggering factors of acute PACG attack after the COVID-19 outbreak were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Xuzhou First People's Hospital (No.xyyll[2023]114).Written informed consent was obtained from each subject.Results:The proportion of acute PACG patients in Xuzhou First People's Hospital within one month after the outbreak in 2022 to 2023 increased significantly compared with the same period in 2021 to 2022, 2020 to 2021 and 2019 to 2020, and the differences were statistically significant ( χ2=31.066, 33.331, 20.804; all at P<0.001).There was no statistical significance in the distribution of the number of eyes with different grades of visual acuity, IOP, the number of eyes with IOP ≥30 mmHg (1 mmHg=0.133 kPa), and the distribution of the number of eyes with different anterior chamber angles between the two groups (all at P>0.05).Patients in the control group had no history of COVID-19 infection or use of cold medicines at disease onset.During disease onset, all 92 (100%) patients in the study group had positive COVID-19 nucleic acid test results, of which 57 (61.96%) patients had a history of oral anti-cold medication use.During the same period, 49 (100%) hospitalized patients with other types of glaucoma had positive COVID-19 nucleic acid test results, of which 20 (40.82%) patients had a history of oral cold medication.There was a statistically significant difference in the proportion of patients taking oral cold drugs between acute PACG and other types of glaucoma in the study group ( χ2=5.764, P=0.016).During the outbreak of COVID-19, the study group reported that the daily water intake had increased to varying degrees than before.In the study group, 76 patients had anxiety, accounting for 82.6%.Multiple linear regression analysis showed that IOP=19.052+ 0.009×daily water intake+ 0.858×HADS score ( R2=0.780), and the standardized coefficients of daily water intake and HADS score were 0.542 and 0.452, respectively.Daily water intake had a greater effect on IOP than HADS score. Conclusions:The proportion of acute PACG patients among hospitalized surgical glaucoma patients increased significantly after the COVID-19 outbreak, which is related to risk factors such as oral anti-cold medications containing vasoconstrictors or antihistamines, increased daily water intake, anxiety and other lifestyle, and mood changes.

The immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome is the only known human genetic disease involving DNA methylation defects.About 50% of the cases are caused by the compound heterozygous mutation of DNMT3B gene.About a hundred cases were reported in the world, but only a few cases came from China.There may be a misdiagnosis and missed diagnosis.To the best of our knowledge, no Chinese article systematically discusses the ICF syndrome.This paper aims to review the possible mechanisms, clinical manifestations, genetic characteristics, treatment, and prognosis of the ICF syndrome, and to improve Chinese doctors′ knowledge about this disease.

Children with certain comorbidities and immunocompromising conditions are highly vulnerable to SARS-CoV-2 infection. Vaccination against SARS-CoV-2 is an important strategy to reduce death， critical illness and overall disease burden. With the evolving and increasing transmission of SARS-CoV-2， universal vaccination is essential to achieve this goal. Children with special medical conditions are considered as the priorities for SARS-CoV-2 vaccination. However， vaccine hesitancy towards the implementation of SARS-CoV-2 vaccination currently remains an urgent challenge. In order to promote the sustainable vaccination for those children in Shanghai as well as China， Shanghai municipal center for disease control and prevention， together with the national children’s medical center， children’s hospital of Fudan university and the expert group on immunization planning of the Shanghai preventive medicine association， organized a consensus expert working group to formulate the evidence-based recommendations and implementation suggestions for children with common chronic diseases， allergy history， diseases involving adverse events related to vaccination， and immunocompromising conditions， based on the published evidence of SARS-CoV-2 vaccination for populations and children with special medical conditions.

Objective:To investigate the effect of peripheral blood neutrophil to lymphocyte ratio (NLR) and platelet distribution width (PDW) on the clinical prognosis of childhood medulloblastomaMethods:Clinical data and survival data of 76 pediatric patients who were diagnosed as medulloblastoma by post-operative pathology in the First Affiliated Hospital of Zhengzhou University from January 2009 to December 2016 were collected. Kaplan- Meier method was used to calculate the overall survival(OS) and progression free survival(EFS) rates, Log- rank test was employed to compare the survival rates of different groups, and Cox proportional hazards regression model was used for multivariate analysis. Results:The log- rank test revealed that 5-year PFS rate and OS rate (22.2%, 22.2%) in the high NLR group (NLR>4.94) were significantly lower than those in the low NLR group (NLR≤4.94) (45.6%, 55.7%), and the differences were statistically significant(PFS: P=0.009, OS: P=0.001), and the 5-year PFS and OS (52.3%, 66.5%) of the high PDW group (PDW>15.90) were significantly higher than those in the low PDW group (PDW ≤ 15.90) (27.1%, 32.5%), and the differences were statistically significant(PFS: P=0.032, OS: P=0.039). Univa-riate analysis showed that the extent of resection (PFS: P=0.006, OS: P=0.009), and postoperative radiotherapy (PFS: P=0.011, OS: P=0.001) and postoperative radiotherapy(PFS: P=0.011, OS: P=0.001) were the factors influencing the prognosis of children with medulloblastoma.Multivariate Cox proportional hazards regression model analysis suggested that no postoperative radiotherapy (PFS: P=0.048, OS: P=0.008), NLR>4.94 (PFS: P=0.023, OS: P=0.003) and PDW≤15.90 (PFS: P=0.028, OS: P=0.006) were the independent risk factors for the prognosis of childhood medulloblastoma. Conclusions:Increased NLR and decreased PDW indicate unfavorable prognosis of the childhood medulloblastoma.Therefore, preoperative NLR and PDW may be the potential prognostic markers for childhood medulloblastoma.

Objective: To investigate and analyze the actual intake of protein and energy in adult patients with severe burns during post burn days (PBDs) 3 to 14. Methods: Records of 52 adult patients with severe burns [37 males and 15 females, (37±9) years old], admitted to the Department of Plastic Surgery and Burns of Tianjin First Central Hospital from January 1st 2011 to December 31st 2017 and meeting the study inclusion criteria, were retrospectively analyzed. Nutrition intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations of patients during PBDs 3 to 14 were obtained from critical care records. During PBDs 3 to 7 and PBDs 8 to 14, the personal daily total energy intake and the ratio of it to energy target of patients were calculated and compared; the personal daily intake of carbohydrate, fat, and protein and calorigenic percentages of carbohydrate, fat, and protein accounted for total energy intake, and the ratios of non-protein calories to total nitrogen of patients were calculated and compared; the personal daily energy and protein intake of patients from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations were analyzed; the percentages of energy intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations accounted for total energy intake, and the percentages of protein intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations accounted for total protein intake of patients were calculated. Vomiting and diarrhea of patients during PBDs 3 to 7 and PBDs 8 to 14 were recorded. Levels of serum albumin, prealbumin, blood glucose, and triglycerides, 24-hour excretion of urinary nitrogen, nitrogen balance values of patients on PBDs 7 and 14 were recorded or calculated. Data were processed with paired t test and chi-square test. Results: (1) The personal daily total energy intake of patients during PBDs 3 to 7 and PBDs 8 to 14 were (8 696±573) and (11 980±1 259) kJ respectively, and ratios of them to energy target [(13 290±1 561) kJ] were 65.4% and 90.1% respectively. The personal daily total energy intake of patients during PBDs 3 to 7 was obviously lower than that during PBDs 8 to 14 (t=18.172, P<0.01). (2) The personal daily intake of carbohydrate, fat, and protein of patients during PBDs 8 to 14 were obviously higher than those during PBDs 3 to 7 (t=15.628, 22.231, 10.403, P<0.01). The personal daily calorigenic percentages of carbohydrate, fat, and protein accounted for total energy intake of patients were 56.8%, 25.1%, and 18.3% respectively during PBDs 3 to 7 and 54.2%, 27.0%, and 18.7% respectively during PBDs 8 to 14. The calorigenic constituent ratio of personal daily intake of carbohydrate, fat, and protein accounted for total energy intake of patients during PBDs 3 to 7 was close to that during PBDs 8 to 14 (χ²=0.185, P>0.05). The ratios of non-protein calories to total nitrogen (kJ∶g) of patients during PBDs 3 to 7 and PBDs 8 to 14 were 469∶ 1 and 456∶ 1 respectively. (3) The personal daily energy intake of patients from routes of oral diet and parenteral nutrition preparations during PBDs 8 to 14 [(4 394±978), (5 723±898) kJ] were obviously higher than those during PBDs 3 to 7 [(2 137±453), (4 855±825) kJ, t=26.516, 6.583, P<0.01], while the personal daily energy intake of patients from routes of enteral nutrition preparations during PBDs 8 to 14 was close to that during PBDs 3 to 7 (t=1.922, P>0.05). The constituent ratio of personal daily energy during PBDs 3 to 7 was close to that during PBDs 8 to 14 (χ²=4.100, P>0.05). The personal daily protein intake of patients from route of oral diet during PBDs 8 to 14 was (58±22) g, obviously higher than (25±6) g during PBDs 3 to 7 (t=14.514, P<0.01). The personal daily protein intake of patients from routes of enteral nutrition preparations and parenteral nutrition preparations during PBDs 8 to 14 was close to those during PBDs 3 to 7 (t=1.924, 1.110, P>0.05). The constituent ratio of personal daily protein intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations accounted for total protein intake during PBDs 8 to 14 was close to that during PBDs 3 to 7 (χ²=5.634, P>0.05). (4) There were 3 patients with vomiting and 4 patients with diarrhea during PBDs 3 to 7, and 1 patient experienced both of them during PBDs 8 to 14. The levels of serum albumin, prealbumin, blood glucose, and triglycerides, 24-hour excretion of urinary nitrogen, and nitrogen balance values of patients on PBDs 7 and 14 were (29±4) and (30±4) g/L, (132±42) and (171±48) mg/L, (7.4±2.8) and (6.7±2.8) mmol/L, (1.5±0.7) and (1.4±0.7) mmol/L, (30.5±4.3) and (34.5±2.2) g, -(25.1±2.6) and -(23.7±3.9) g, respectively. Conclusions The personal daily total energy intake of patients during PBDs 3 to 7 was lower than that during PBDs 8 to 14. The calorigenic constituent ratio of personal daily intake of carbohydrate, fat, and protein accounted for total energy of patients during PBDs 3 to 7 was close to that during PBDs 8 to 14. Energy and protein intake were mostly derived from parenteral nutrition preparations during PBDs 3 to 7, while those during PBDs 8 to 14 were mainly derived from parenteral nutrition preparations and oral diet.
