Fingertip and venous blood lactate concentrations were determined pre-exercise and after 4-min bouts of treadmill running at 2.69, 3.13, 3.58 and 4.03 m s-1 in 14 normal healthy volunteers. A 1-min rest period intervened each exercise period, and was used for the simultaneous sampling of fingertip and venous blood. Compared to pre-exercise, fingertip and venous blood lactate (BLa) concentrations increased significantly (P < 0.05) in a progressive pattern with increasing exercise intensity. Fingertip BLa concentrations were significantly higher (P < 0.05) than venous blood prior to exercise and in response to all four running speeds. Treadmill speed, heart rate and oxygen consumption were significantly lower (P < 0.05) at a BLa concentration of 4 mM when estimated from fingertip blood as compared with venous blood. These results indicate that differences between fingertip and venous blood exist during treadmill exercise and should be considered when lactate determination is employed as a criterion to evaluate and predict performance and when used as a training guide to standardize exercise intensity.

Vitiligo is considered as depigmenting skin disorder where patches of skin losing their pigment. Lipocalin-2 (LCN2) is one of the Inflammatory adipokines that has a potential role in skin disorders and other inflammatory diseases as well. To measure the concentration level of LCN2 in vitiligo patients compared to healthy controls and to investigate its relation to disease activity and other clinical data to evaluate its role in the pathogenesis of the disease.

Introduction: Anticoagulant therapy is critical for venous thromboembolism (VTE) management, though bleeding remains a major concern, ranging from mild to fatal events. This study aimed to assess the predictive value of cytokines for major bleeding in patients with acute pulmonary embolism (PE).
Methods: In this prospective, observational study, patients aged ≥ 18 years with acute PE were enrolled from April 2021 to September 2022 and followed for 30 days.
[Berberine ameliorates coronary artery endothelial cell injury in Kawasaki disease through complement and coagulation cascades].

Objectives: To explore the role of berberine (BBR) in ameliorating coronary endothelial cell injury in Kawasaki disease (KD) by regulating the complement and coagulation cascade.
Methods: Human coronary artery endothelial cells (HCAEC) were divided into a healthy control group, a KD group, and a BBR treatment group (=3 for each group). The healthy control group and KD group were supplemented with 15% serum from healthy children and KD patients, respectively, while the BBR treatment group received 15% serum from KD patients followed by the addition of 20 mmol/L BBR.
Clinical value of miR-200b in diagnosis and prognosis of childhood pneumonia.

Department of Pediatrics, Tongde Hospital of Zhejiang Province, No. 234, Gucui Road, Hangzhou, 310000, China.
Background: Childhood pneumonia (CP) is a common respiratory infectious disease in children with high morbidity and mortality. However, differential changes in miRNAs may interact with the regulation of CP. The aim of this paper was to discuss the miR-200b expression in CP and its diagnostic and prognostic value.
