Objectives To investigate the clinical significance of the airway inflammation mediators,eosinophil cationic protein (ECP) and urinary leukotriene E4 (LTE4),in children with respiratory syncytial virus (RSV) bronchiolitis. Methods A total of 120 inpatients with RSV bronchiolitis were classified into atopic and non-atopic groups. And 30 healthy subjects were se-lected as normal controls. Urinary LTE4 was determined by ELISA and ECP concentration in nasopharyngeal secretions (NPS) was tested by UniCAP100 allergen detector. The differences among groups were compared. Results The urinary LTE4 level in atopic group (172.21 ± 67.29 pg/ml) was elevated significantly (P<0.01) than that of non-atopic group (78.21 ± 28.78 pg/ml) and control group (44.22±16.14pg/ml). Significance was also found between non-atopic and control groups (P<0.01). Statistical anal-ysis indicated that urinary LTE4 positively correlated to serum IgE and ECP in children with RSV bronchiolitis (r=0.57,0.49;P<0.01). Conclusions The level of urinary LTE4 and ECP in NPS can provide the reference for treatment and prognosis of children with RSV bronchiolitis.

Objective To compare effect and psychological state between ICU and conventional treatment in elderly patients with ischemic heart failure.Methods A total of 64 consecutives diagnosed as ischemic heart failure in the Second Center Hospital of Baoding from June 2013 to June 2014 were divided randomly into experiment and control group, each of 32 cases, after getting approval of our hospital's ethics committee and informed consent right of patients ,family members.The patients in experiment group were advised into ICU, and the patients in control group were into common ward, then compared the differences of cardiac functions,clinical effect and scale anxiety score (SAS), scale depression score (SDS).Results The left ventricular end diastolic diameter (LVEDd), ejection fraction (EF) and NYHA class in the two groups after treatment were both better than before, and the experiment group were significantly better than the control group (LVEDd: (56.7±4.1) mm vs.(59.2 ± 4.6) mm;EF : 0.49 ± 0.05 vs.0.42 ± 0.04;NYHAI degree: 23 vs 22;NYHA Ⅱ-Ⅲ degree: 11 vs 17;t =3.105,3.416;x2 =0.714,3.513;P＜0.05).The in-hosptical days and fees in experiment group were significantly less than the control group(t =3.846,3.913;P＜0.05).The treatment types in the two groups were no statistical difference (P ＞ 0.05).The death rate in-hosptical and follow-up in experiment group were both significantly lower than the control group(9.4％ vs.21.9％;12.5％ vs.28.1％;x2 =3.102,3.715;P＜0.05).The SAS, SDS scores in the two groups after treatment were both higher than before, and the control group were significantly higher than the treatment group(t =3.326,3.845;P＜0.05).Conclusion The serious condition of elderly patients with ischemic heart failure are better to ICU, which could greatly improve clinical effect and anxiety depression.

Objective To characterize contemporary electrographic neonatal seizures by video electroencephalogram (VEEG) and to assess the value and the limitations of two-channel (C3-C4/T3-T4) amplitude-integrated electroencephalogram (aEEG) plus original EEG signals used to diagnose neonatal seizure with video EEG as a golden standard.Methods Sixty-six neonates admitted to Children's Hospital of Fudan University from January 2011 to July 2011 with clinical or suspected clinical seizure were investigated and bedside VEEG were recorded for more than 3 hours.VEEG signals were transformed into three kinds of aEEG signals by Galileo NT PMS software:one-channel aEEG (C3-C4),one-channel aEEG (C3-C4) plus original EEG,two-channel aEEG (C3-C4/T3-T4) plus original EEG.Electrical seizure activity on VEEG was signed out with respect to its occurrence,duration and localization of seizure onset; while aEEG seizure was recorded only with its occurrence.The relationship between aEEG and VEEG was analyzed by Spearman analysis.The value and the limitations of aEEG to diagnose neonatal seizure were evaluated by sensitivity,specificity,positive predictive value and negative predictive value.Results A total of 62 traces were suitable for analysis.(1) VEEG showed 39 seizure activities,among which 8 status epilepticus; and the rest 31 neonates had 352 non-status epilepticus electrical seizures,79.3％ (279/352) of which occurred over the centrotemporal region.(2) Eight cases with status epilepticus on VEEG were all diagnosed as status epilepticus on aEEG.For non-status epilepticus electrical seizures,the sensitivity of aEEG for detection of electrical seizures was as followed:49.1％ (173/352) for one-channel aEEG,54.5 ％ (192/352) for one-channel aEEG plus original EEG,81.2％ (286/353) for two-channel aEEG plus original EEG.Results from one-channel aEEG,one-channel aEEG plus original EEG and two-channel aEEG plus original EEG were all related to VEEG (ρ =0.790,0.907 and 0.953,respectively,P＜ 0.01).(3) Sensitivity of seizure detection was 66.7％ (26/39,95％ CI:0.62-0.81) for one-channel aEEG,74.4％(29/39,95％ CI:0.78-0.96) for one-channel aEEG(C3-C4) plus original EEG and 89.7％ (35/39,95％ CI:0.89-1.00) for two-channel aEEG(C3-C4/T3-T4) plus original EEG.Conclusions VEEG might help aEEG in diagnosis of neonatal seizure.two-channel aEEG (C3-C4/T3-T4) plus original EEG could significantly increase the sensitivity of neonatal seizures indentification.

Objective:To investigate the protective effects of levosimendan combined with lyophilized recombinant human brain natriuretic peptide (rhBNP) on myocardium in patients with acute myocardial infarction complicated by heart failure.Methods:140 patients with acute myocardial infarction complicated by heart failure who received treatment in Changxing People's Hospital from June 2018 to June 2020 were included in this study. They were randomly assigned to receive either routine treatment (control group, n = 70) or routine treatment, levosimendan combined with rhBNP (study group, n = 70). Serum levels of creatine kinase (CK)-MB, cardiac troponin I (cTnI), lactate dehydrogenase (LDH), high-sensitivity C-reactive protein (hs-CRP), which were associated with myocardial injury, were measured in each group. In addition, the changes in cardiac ultrasound indexes left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD) and left ventricular ejection fraction (LVEF) were observed. Clinical effects on heart failure were evaluated. Adverse drug reactions were monitored during the treatment. Results:After treatment, CK-MB, cTnI, LDH and hs-CRP levels in the study group were (56.73 ± 12.15) U/L, (0.41 ± 0.19) μg/L, (126.83 ± 15.26) U/L and (1.59 ± 0.27) mg/L, respectively, which were significantly lower than those in the control group [(78.52 ± 14.07) U/L, (0.68 ± 0.21) μg/L, (187.25 ± 23.04) U/L, (2.84 ± 0.41) mg/L, t = 5.569-12.418, all P < 0.05]. LVEDD and LVESD in the study group were significantly lower than those in the control group, while LVEF in the study group was significantly higher than that in the control group ( t = 4.435-6.426, all P < 0.05). Total effective rate in the study group was significantly higher than that in the control group [88.57% (62/70) vs. 72.86% (51/70), χ2 = 5.552, P < 0.05]. There was no significant difference in total incidence of adverse drug reactions between study and control groups [11.43% (8/70) vs. 8.57% (6/70), χ2 = 0.317, P > 0.05]. Conclusion:Levosimendan combined with rhBNP can effectively alleviate myocardial injury in patients with acute myocardial infarction complicated by heart failure, improve myocardial function, is highly safe, and thereby deserves clinical application.

Objective:The study was planned to evaluate the clinical utility of microcytic anemia factor (MAF) and low hemoglobin density (LHD%) in the screening of iron deficiency in blood donors.Methods:A total of 400 blood donors, 200 male and 200 female, were randomly admitted to Fujian Blood Center from January1, 2022 to February 28, 2022 by the way of stratified sampling. According to the fourth edition of Diagnostic and therapeutic criteria for hematological diseases, the patients were divided into three groups: normal group (N=299), iron depletion group (ID, n=54) and iron deficient erythropoiesis group (IDE, n=47), Blood routine indexes including hemoglobin (HGB), mean corpuscular volume hemoglobin (MCV), mean corpuscular hemoglobin content (MCH), mean corpuscular hemoglobin concentration (MCHC) and iron metabolism indexes including serum ferritin (SF), serum iron (SI), total iron binding capacity (TIBC), transferrin saturation (TS) and unsaturated iron binding capacity (UIBC) were measured, MAF and LHD% were calculated by formula.One-way ANOVA or Kruskal-Wallis H tests were used to analyze the differences among three groups. Spearman correlation analysis was used to analyze the correlation between MAF and LHD% and iron metabolism indexes.The Receiver Operating Characteristic (ROC) curve was used to evaluated the diagnostic value of MCH, MCHC, MAF and LHD% for iron deficiency in blood donors. Results:MAF in ID group which was 11.81±0.81 were higher than the IDE group which was 10.69±0.95 and lower than the healthy group which was 13.17±1.24, the total difference among the three groups was statistically significant ( F=110.784, P<0.001), the difference between two groups was statistically significant ( P<0.01); LHD% in ID group which was 2.61 (1.87, 3.91)% were lower than the IDE group which was5.60(2.99, 8.02)% and higher than the healthy group which was1.74 (1.22, 2.73)%, the total difference among the three groups was statistically significant ( H=62.166, P<0.001), the difference between two groups was statistically significant ( P<0.01).In 101 iron deficiency blood donors, Spearman correlation analysis showed that MAF was positively correlated with SF, SI and TS ( r=0.426, P<0.01; r=0.547, P<0.01; r=0.566, P<0.01);contrarily, LHD% was negatively correlated with SF, SI and TS ( r=-0.397, P<0.01; r=-0.400, P<0.01; r=-0.479, P<0.01).The areas under the ROC curve of MCH, MCHC, MAF and LHD% diagnostic ID were 0.745, 0.646, 0.819 and 0.646, respectively;the cut-off value of MAF was 12.56, with a sensitivity of 67.90% and a specificity of 83.30%.While the areas under the ROC curve of MCH, MCHC, MAF and LHD% diagnostic IDE were 0.901, 0.834, 0.941 and 0.834, respectively; the cut-off value of MAF was 11.73, with a sensitivity of 87.60% and a specificity of 87.20%. Conclusions:MAF performed a high diagnostic value of iron deficiency, especially IDE, and can be used as a marker in the diagnosis of iron deficiency in blood donors.

To report 2 cases of Iso-Kikuchi syndrome, both of which were congenital. Case 1, a 7-month-old female infant, visited the hospital due to abnormalities in the nail plate of the left index finger for 7 months; case 2, a 3-year-old male child, also visited the hospital due to abnormalities in the nail plate of the left index finger for 3 years. The 2 patients both presented with 2 tiny, independent nail plates on both sides of the nail bed of the left index finger, instead of normal nail plates. Based on their clinical features, the 2 patients were diagnosed with Iso-Kikuchi syndrome (congenital onychodysplasia of the index finger). The mother of case 1 had a history of progesterone use to prevent miscarriage during pregnancy, the mothers of the two patients both suffered from hypothyroidism and continued to receive thyroid hormone replacement therapy during pregnancy, and the mother of case 2 had a history of gestational diabetes. It is still unclear whether these comorbidities and drugs are directly related to the occurrence of Iso-Kikuchi syndrome.

Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.

Objective:To evaluate clinical efficacy and safety of topical compound oleum lithospermi in the treatment of mild to moderate diaper dermatitis.Methods:A multicenter, randomized, positive-drug parallel-controlled clinical trial was conducted in 19 hospitals from July 2019 to August 2020. Children aged 0 - 12 months with mild to moderate diaper dermatitis were enrolled and randomly divided into 2 groups using a random number table: test group topically treated with compound oleum lithospermi, and control group topically treated with zinc oxide cream. The treatment was carried out 6 - 8 times a day for 7 days. Visits were scheduled on days 0 and 7, and total response rate and clinical healing time were evaluated. Changes in the dermatitis family impact (DFI) score were compared between the test group and control group, and adverse events were recorded. Statistical analysis was carried out by using independent-sample t test for normally distributed continuous data, Wilcoxon rank sum test for non-normally distributed continuous data, and chi-square test or Fisher′s exact test for unordered categorical data; survival curves were drawn, and log-rank test was used for comparisons between two groups. Results:A total of 343 children with diaper dermatitis were enrolled in this study. Among them, 31 children violated the protocol, so 312 were included in the per protocol set, including 157 in the test group and 155 in the control group, and all completed the visits on days 0 and 7. The total response rate was significantly higher in the test group (87.26%, 137/157) than in the control group (78.71%, 122/155; χ2 = 4.04, P = 0.044) . The clinical healing time was significantly shorter in the test group (5.33 days) than in the control group (6.13 days; χ2 = 4.67, P = 0.025) . After 7-day treatment, the DFI score significantly decreased in both the 2 groups compared with that before the treatment, but there was no significant difference in the DFI score between the 2 groups (test group: 4.02 ± 6.96, control group: 3.58 ± 5.90, Z = -0.39, P = 0.686) . The incidence of adverse events was 2.92% (5/171) and 5.45% (9/165) in the test group and control group respectively, and there was no significant difference between the 2 groups ( χ2 = 0.03, P = 0.865) . Conclusion:Compound oleum lithospermi can markedly reduce the clinical severity of diaper dermatitis, improve the total response rate, shorten the clinical treatment period, and improve the quality of life of children′s families with a favorable safety profile.

Objective: To explore the correlation between serum high density lipoprotein (HDL) levels and cognitive function in patients with bipolar disorder. Methods: A total of 99 patients with bipolar disorder were enrolled from the inpatient of Suzhou Guangji Hospital.Serum HDL levels were measured by enzymatic colourimetry.Cognitive function was assessed by the repeatable battery for the assessment of neuropsychological status (RBANS). The relationship between serum high density lipoprotein and cognitive function was analyzed by correlation analysis and stepwise multiple regression analysis. Results: Serum HDL levels ((1.39±0.55)mmol/L)were positively correlated with the RBANS total score (68.92±12.48)(r=0.238, P=0.034) and language score(80.59±15.97) (r=0.239, P=0.033) in patients with bipolar disorder.Stepwise multiple regression analysis showed that serum HDL level was the influencing factor of total score of RBANS(β=4.791, t=2.151, P=0.035)and speech function(β=7.363, t=2.247, P=0.027). Conclusion Serum HDL levels can influence cognitive function, especially speech function in patients with bipolar disorder.
