Objective To investigate the predictive value of heparin-binding protein(HBP)in Kawasaki disease complicated with bacterial infection.Methods A total of 148 children with Kawasaki disease in this hospital from April 2021 to June 2022 were selected as Kawasaki disease group.According to the results of pathogen detection during hospitalization,the children were divided into three subgroups:Mycoplasma pneu-moniae group(36 cases),bacteria group(19 cases),and non-infection group(93 cases).In addition,35 chil-dren with fever and upper respiratory tract infection were randomly selected as the case control group.HBP and other inflammatory markers[white blood cell count(WBC),neutrophil percentage(NE％),procalcitonin(PCT),C reactive protein(CRP),interleukin-6(IL-6)]in each group were detected and analyzed.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of HBP and PCT for bacterial infection in children with Kawasaki disease.Results The levels of HBP,WBC,NE％,CRP and IL-6 in the Ka-wasaki disease group were significantly higher than those in the case control group(P＜0.05),while there was no significant difference in PCT level between the two groups(P＞0.05).The levels of HBP,WBC,NE％,PCT,CRP and IL-6 in children with Kawasaki disease after treatment were significantly lower than those at admission(P＜0.05).The levels of HBP and PCT in the bacterial group were higher than those in the Mycoplasma pneumoniae group and the non-infection group,and the differences were statistically signifi-cant(P＜0.05),while there were no statistically significant differences in WBC,NE％,CRP and IL-6 levels a-mong the three groups(P＞0.05).ROC curve results showed that the area under the curve(AUC)and 95％CI of HBP for predicting bacterial infection in children with Kawasaki disease was 0.77(0.68-0.86),when HBP was 499.65 ng/mL,the sensitivity and specificity were 84.2％and 66.7％,respectively.When PCT was 0.85 ng/mL,the AUC(95％CI)for predicting bacterial infection in children with Kawasaki disease was 0.65(0.52-0.78),and the sensitivity and specificity were 63.2％and 65.9％,respectively.Conclusion HBP is associated with Kawasaki disease,and it has certain predictive value for Kawasaki disease complicated with bacterial infection.

Objective:To evaluate the clinical outcome of the reconstruction of finger-pulp defects, using modified dorsal digital fasciocutaneous flap.Methods:Between June 2018 and March 2019, 14 patients with finger-pulp defects were admitted to the Department of Hand and Foot Surgery. There were 14 males and 2 females, aged from 27 to 63 years, with the mean age of 49 years. The defect areas of finger pulp were 1.6 cm × 1.4 cm-2.5 cm × 1.6 cm. All of the finger-pulp defects were treated by the modified dorsal digital fasciocutaneous flap and the inverted L-shaped incision was made at the distal part of the pedicle. The defects at donor sites were reconstructed with full-thickness skin grafts harvested from the forearm. Viability of the flap was recorded postoperatively. At the last follow-up, aesthetics, sensibility of the flap and hand performance were assessed.Results:All of the 14 flaps survived successfully, the areas were 1.8 cm×1.6 cm-2.7 cm×1.8 cm. Partial distal blister occurred on the flap in only one case, which was solved by aspiration without surgical intervention. All cases acquired follow-up visits for 5 to 12 months with a mean time of 8.9 months. The texture of flaps was similar to surrounding skin and the shape of reconstructed finger pulp was satisfactory. According to the assessment of total active movement, the results were excellent in 9 fingers, good in 5 fingers. The 2-point discrimination of flap was 8 to 11 mm (mean, 9.9 mm).Conclusions:It is an effective and simple method for the reconstruction of finger-pulp defects using modified dorsal digital fasciocutaneous flap. The clinical effectiveness is definite.

Objective To analyzed the left ventricular (LV) regional and global strains in coronary artery stenosis by using three-dimensional speckle tracking imaging (3D-STI) and two-dimensional speckle tracking imaging (2D-STI) for the assessment of left ventricular systolic function,and to compare the clinical values between 3D-STI and 2D-STI in the detection of coronary stenosis.Methods 39 patients with coronary artery stenosis and 32 sex-age matched controls were enrolled in this study.Coronary artery stenosis group was divided into ischemic group and non-ischemic group.Real-time three dimensional full volume and two-dimensional dynamic image of the LV were obtained and then analyzed by off-line analysis software.The parameters of 3D-STI were three-dimensional longitudinal strain (3D-LS),circumferential strain (3D-CS),radial strain (3D-RS),area strain (3D-AS),global longitudinal strain (3D-GLS),global circumferential train (3D-GCS),global radial strain (3D-GRS) and global area strain (3D-GAS).The parameters of 2D-STI were two-dimensional longitudinal strain (2D-LS),circumferential strain (2D-CS),radial strain (2D-RS),global longitudinal strain (2D-GLS),global circumferential train (2D-GCS) and global radial strain (2D-GRS).The global/regional strains derived from 3D-STI and 2D-STI in patient group and controls were analyzed for comparing their efficacy in detecting coronary artery stenosis.Results Compared with non-ischemic group,2D-LS,2D-CS,3D-LS,3D-CS and 3D-AS were lower in ischemic group (P ＜0.05).ROC curves showed the sensitivity of 2D-LS,3D-LS and 3D-AS for the diagnosis of myocardial ischemia was 60.1％,64.2 ％ and 74.0 ％,while the specificity of them was 60.0％,61.0％ and 63.1％,respectively.There was no significant difference in 2D-GCS and 2D-GRS between coronary artery stenosis group and control group (P ＞ 0.05).Compared with control group,2D-GLS,3D-GLS,3D-GCS,3D-GRS and 3D-GAS were significantly lower in coronary artery stenosis group (P ＜0.05).ROC curves showed the sensitivity of 2D-GLS,3D-GLS and 3D-GAS in the diagnosis of coronary artery stenosis was 61.3％,73.3％ and 79.3 ％,while the specificity was 65.4％,66.0 ％ and 70.8 ％,respectively.The sensitivity and specificity of 3D-GAS were the highest in these parameters.It is revealed that 2D-GLS,2D-GCS and 2D-GRS were correlated with LVEF (r1 =-0.668,P1 ＜0.001 ;r2 =-0.551,P2 ＜0.001 ;r3 =0.310,P3 ＜0.05),and 3D-GLS,3D-GCS,3D-GRS,3D-GAS were correlated with LVEF (r1 =-0.634,P1 ＜0.001 ;r2 =-0.672,P2＜0.001 ;r3 =0.698,P3＜0.001 ;r4 =-0.707,P4＜0.001).The correlate of 3D-GAS and LVEF was higher than other parameters.Conclusions 3D-STI is superior to 2D-STI in assessing regional and global left ventricular systolic function in patients with coronary artery stenosis,and 3D-GAS derived from 3D-STI is a ideal parameter of detecting significant coronary artery stenosis based on its highest sensitivity and specificity.

Objective To study the drug resistance of neonatal sepsis caused by Klebsiella pneumoniae and provide evidence for drug treatment. Method Retrospectively analysis was conducted on the clinical data and antibiotic resistance of Klebsiella pneumoniae in 50 neonates with sepsis. Results The majority of the 50 cases were infected in hospital. There were 13 ESBLs strains in 50 Klebsiella pneumoniae strains (26%), and the others were negative ESBLs starins (74%). All the strains were multidrug-resistance to the β-lactam antibiotics and only sensitive to few antibiotics such as Imipenem and Amikacin. The sensitive rate was 100%. Conclusions The first selected antibiotic for the treatment of neonatal sepsis caused by Klebsiella pnemoniae was Imipenem or Amikacin.
