Objective To explore the serum levels changes of heart-type fatty acid-binding protein and brain natriuretic peptide in children with Kawasaki disease,as well as their links with the heart function. Methods A total of 53 children with Kawasaki disease admitted to our hospital from February 2008 to March 2012 were selected and at the same time 50 healthy controls were randomly selected. The serum levels for the children in acute phase,recovery period of Kawasaki disease and control group children were determined by en-zyme-linked immnoabsorbent assay. The internal diameter of coronary artery,LVEF,LVSF,CI and E/A of chil-dren were measured by two-dimensional echocardiography. Results The heart-type fatty acid-binding protein and brain natriuretic peptide concentrations of children with Kawasaki disease in acute stage[(18. 23 ± 13. 81) ng/ml,(517. 2 ±213. 2) pg/ml] were higher than those in recovery stage[(6. 29 ± 1. 26) ng/ml,(92. 1 ± 46. 0) pg/ml](P<0. 05). They were also higher for children in acute stage than those of control group[(6. 26 ± 1. 60) ng/ml,(37. 6 ± 7. 6) pg/ml]. The LVEF,LVSF,CI of Kawasaki disease for children in acute stage were lower than those in recovery phase[(60. 3 ± 3. 6)% vs. (64. 8 ± 4. 3)%,(30. 6 ± 2. 5)% vs. (34. 9 ± 1. 9)%,(3. 1 ± 0. 3)% vs. (3. 5 ± 0. 3)%]. Linear correlation analysis showed the heart-type fatty acid-binding protein and brain natriuretic peptide′concentrations in Kawasaki disease were negatively correlated with LVEF (P<0. 05). The heart-type fatty acid-binding protein′positive rates were also higher than brain natriuretic peptide for the children in acute and recovery phase. Conclusion The heart-type fatty acid-binding protein and brain na-triuretic peptide could be used as the biochemical markers for myocardial damage of children with Kawasaki dis-ease. The heart-type fatty acid-binding protein was more significant than brain natriuretic peptide. The heart-type fatty acid-binding protein and brain natriuretic peptide in Kawasaki disease were also high in recovery stage,indi-cating that myocardial damage could maintain for a long period after the clinical improvement.

Abstract Blood donation institutions mainly rely on manual identification for pre-donation health screening of blood donors. To further ensure the safety of blood donation and minimize the participation of unqualified donors, Ningbo Central Blood Station developed and launched a pre-blood donation health screening software as a supplement to the manual identification in May 2023. The software establishes preset rules based on the conditions of donors who are ineligible or temporarily ineligible to donate blood in Whole Blood and Component Donor Selection Requirements (GB 18467-2011), retrieves the health records of blood donors from the Ningbo National Health Information System and compares with the preset rules. When a preset rule is triggered, the medical examiner receives a warning. The pre-donation health screening software effectively enhances the capabilities of blood donation institutions in identifying unqualified donors. It is conducive to promoting the standardization of the pre-donation health screening process, the intelligence of blood donation services and blood management, and the establishment of a more scientific and efficient pre-donation health screening procedure.

[Objective] To observe the dynamic changes of circulating immune complex (CIC) in monkeys infected by simian immunodeficiency virus (SIV). [Methods] Agglutination test of complement-sensitized yeast cell was used to determine the serum CIC level in 30 cases of monkeys, which were infected with SIVmac251 and sampled in different time-points after infection. Sixty-eight cases of normal monkeys were also examined as controls. [Results] After SIV infection, CIC can't be detected in all 30 monkeys until the 4th week, the total positive rate being 30% . In the 8th week, CIC were detected in 46.7% of these monkeys and then declined gradually in the following 12 weeks. Since the 20th week, the CIC in these monkeys maintained lower liter and lower positive rate which was close to that of the normal monkeys (about 10%). [Conclusion] CIC appeared and increased during the primary SIV infection and declined accompanying with the virus clearance from the circulalion. The formation of CIC may not benefit to the control of virus replication and the induction of anti-virus immunity; CIC has a role in the pathogenesis after SIV infection.

Objective To investigate the effects of positive end-expiratory pressure (PEEP) after recruitment maneuvers (RM) on respiratory mechanics and gas exchange during laparoscopy in obese patients.Methods Sixty-three ASA physical status Ⅱ or Ⅲ patients,aged 42-64 yr,with body mass index 30-40kg/m2,were randomly allocated into 3 groups (n=21 each):PEEP0 group,PEEP5 group and PEEP10 group.PEEP was not given after RM in PEEP0 group.In PEEP5 and PEEP10 groups,a recruiting maneuver was followed by PEEP 5 and 10 cm H2 O,respectively,until the end of pneumoperitoneum.The intraabdominal pressure was set at 12mmHg in the three groups.Parameters of respiratory mechanics including peak airway pressure (Ppeak),airway plateau pressure (Peat),chest wall plateau pressure (PplatCW),airway resistance (Raw),elastance of respiratory system (ERS),elastanc of chest wall (ECW) and elastance of lung (EL) and parameters of gas exchange including oxygenation index (PaO2/FiO2),arterial to end-tidal difference in carbon dioxide (Da-ETCO2),alveolar-arterial oxygen tension difference (DA-aO2),and dead space/tidal volume ratio (VD/VT) were measured before pneumoperitoneum (T0),at 20 min of pneumoperitoneum (T1),at 10 min after the end of recruitment (T2),and at the end of pneumoperitoneum (T3).Results Da-ETCO2,ERS and Raw were decreased at T2,ECW and EL were decreased at T3 in PEEP5 group,and Da-ETCO2,VD/VT,DA-aO2,Pplatcw Raw and EL were decreased at T2.3,and PaO2/FiO2 was increased at T2,ECW was decreased at T3 in group PEEP10 as compared with that in group PEEP0 (P ＜ 0.05).Da-ETCO2 and VD/VT were decreased and PaO2/FiO2 was increased at T2,3,Raw was increased and EL was decreased at T2 in group PEEP10 as compared with that in group PEEP5 (P ＜ 0.01).Conclusion PEEP after RM can improve respiratory mechanics and gas exchange during laparoscopy in obese patients and PEEP maintained at 10 cm H2O after RM provides better efficacy than PEEP at 5 cm H2 O.

Essential tremor (ET) is a common dyskinesia disease characterized by tremor. ET is clinically heterogeneous. In addition to the motor symptoms with tremor as the main manifestation, it also includes non-motor symptoms such as neuropsychiatric symptoms (anxiety, depression), personality changes, sleep disorders, etc. Among them, anxiety and depression are the most common, and gradually worsen as the disease progresses, causing adverse effects on the quality of life of patients. Therefore, the early clinical full text of looking for ET psychiatric symptoms seems to have no content of the evaluation scale and is irrelevant. It is suggested that removing biomarkers plays an important role in the diagnosis and treatment of ET patients. Genome-Wide Association Studies (GWAS) describes the SLC1A2 gene associated with ET, and the EAAT2 or GLT1 encoded by this gene is associated with the anxiety and depression phenotypes of ET patients in non-motor symptoms. Up to now, the pathogenesis of ET patients is not clear, but many reports confirm that genetic factors play an important role in the pathogenesis of ET. Among them, SLC1A2 is expected to become a biomarker of the neuropsychiatric phenotype of the disease, providing a basis for clinical workers to take corresponding intervention measures in time. This article reviews SLC1A2 gene and essential tremor.

Background: Bone cancer pain (BCP) is not adequately addressed by current treatment methods, making the exploration of effective management strategies a topic of significant interest. Bone marrow mesenchymal stem cells (BMSCs) seem to be a potential way for managing BCP, yet little is known about the mechanisms underlying the efficacy of this potential treatment. Methods: We established the male C57BL/6 mice BCP models. Behavioral tests, X-ray, bone histology, western blotting, and immunofluorescence were used to verify the analgesic effect of BMSCs. Results: Intramedullary injection of Lewis lung carcinoma cells into the femur successfully generated the mice BCP models. The number of c-Fos-positive neurons and phosphorylated mitogen-activated protein kinase (MAPK) proteins in the spinal dorsal horn of the BCP mice increased. Intrathecal injection of BMSCs temporarily improved the BCP mice’s mechanical and thermal hyperalgesia without affecting motor function. This effect may be related to inhibiting spinal microglia and p-p38 MAPK activation. The analgesic effect of BMSCs may be related to the homing effect mediated by CXCR4. Conclusions Intrathecal injection of BMSCs can temporarily inhibit mechanical and thermal hyperalgesia in BCP mice without affecting motor function. This effect may be related to the inhibition of p-p38 protein expression and the inhibition of microglia but not to p-ERK and p-JNK.
