Objective To evaluate the value of creatine kinase MB(CK-MB) and cardiac troponin I(cTnI)to earlier diagnosis on myocardial injury in newborn infants with asphyxial.Methods Dynamic variation of serum CK-MB and cTnI levels were measured at birth 1,5 and 10 days,respectively,in 40 asphyxia newborn infants and 20 control neonates.Results Serum CK-MB and cTnI levels of asphyxia neonates were significantly higher than those in control group(P0.05).Conclusion The determination of CK-MB and cTnI levels can help the prediction of myocardial injury after asphyxia.

Objective To evaluate the value of ultrasound (US) in assessment knee joint inflammation in patients with juvenile rheumatoid arthritis(JRA).Methods US scans of the knees obtained in 30 children at clinically active stage; JRA was compared with those obtained in 30 healthy children and 10 JRA patients in clinical remission.Results Changes in synovial membrane thickness and presence of fluid in suprapatellar bursa showed statistically significant differences between JRA patients with active disease and the other subjects.Alterations in contour of the articular cartilage were demonstrated in 10 knees of patients with JRA.Conclusion US is a simple sensitive and reliable methods for the assessment and monitoring of knee joint involvement in JRA.

OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

Objective Analyse the change of left ventricular (LV) longitudinal and radial strain in patients with aortic regurgitation (AR) and discuss the relationship between the 2D strain parameter and the filling and ejection of LV. Methods Thirty healthy controls and 45 patients with AR (24 patients with moderate AR and 21 with severe AR) were enrolled in this study, LV systolic global peak radial strain(GRS), systolic global peak longitudinal strain(GLS) and systolic peak longitudinal strain(S), systolic peak longitudinal strain rate(SRs), early diastolic peak longitudinal strain rate(SRe) of every segment were measured or calculated using 2D-STE, early and late diastolic transmitral flow velocity (E, A) were recorded by pulsed Doppler echocardiography and early diastolic mitral annular velocity (Ea) were assessed by tissue Doppler imaging,the E/A and E/Ea ratio were calculated. Discuss the relationship of GLS and LV ejection fraction (LVEF), GLS and E/Ea using the Pearson correlation analysis. Results The GLS were (-20.09±1.47)%, (-18.68±1.52)%, (-12.56±3.25)%and the GRS were (46.71±7.65)%, (43.01±5.95)%, (28.52±6.13)% in control group, patients with moderate and severe AR (MAR group and SAR group) respectively. There were significant differences among the groups (F =82.08,47.69, both P < 0.01) as following:SAR group with control group and MAR group [ q=17.56,13.60 (GLS), q=13.44, 10.20 (GRS), all P<0.01),MAR group and control group [ q=3.42 (GLS), P<0.01]. The SRs of the apical segment were (-1.24±0.22)s-1, (-1.19±0.25)s-1, (-1.04±0.28)s-1 in control group,MAR group and SAR group respectively. There were significant differences among the groups (F=4.47, P < 0.05) as following:SAR group with control group and MAR group ( q=4.02,3.28, both P<0.01). The S, SRe of apical segment and the S,SRs,SRe of basal and midventricular in MAR group were all lower than the control group ( q=4.42, 5.01, 3.48, 3.24, 4.78, 4.12, 3.61, 6.72, all P < 0.01). Pearson correlation analysis revealed the GLS had a relationship with LVEF and E/Ea ( r=-0.73, 0.64, both P<0.01). Conclusion The reduced longitudinal strain and strain rate could detect LV dysfunction in patients with AR in early stage and the GLS had the ability to reflect the diastolic filling and systolic ejecting of the LV.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

Atopic dermatitis (AD) is a chronic, relapsing, inflammatory dermatosis with a variety of clinical manifestations and difficult to cure. Currently, many AD drug candidates have entered the research and development pipeline. In order to provide technical specifications for the clinical development of AD drugs, the Center for Drug Evaluation of National Medical Products Administration released the "Technical Guidelines for Clinical Trials of Drugs for AD Treatment" (Draft for Comments) in November 2022. Non-clinical pharmacodynamics evaluation is an important research before the drug enters clinical trials. Oxazolone (OXA)- and 2,4-dinitro-fluorobenzene (DNFB)-induced models are the most popular classical hapten-induced AD murine models, but variations of modeling are existing in the methods from different studies, including sensitization sites, haptens' dosages, the period of challenges, and the skin lesions severity evaluation as well. In this study, the investigation of OXA- and DNFB-induced AD murine models with various conditions of modeling was performed to compare the characteristics of hapten-induced AD murine models in the pathological process and severity according to the appearance of AD patients, and the guidance of pharmacodynamics evaluation of AD-therapeutic drugs in clinical trials as well, which may provide a proposal for AD treatment drug candidates in the non-clinical pharmacodynamics evaluation. All animal experiments were approved by the Animal Care & Welfare Committee of Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College (approval No.: 00007782 and 00007784).
