Objective To study the effects of different levels of hemodilution during extracorporeal circulation(ECC) on the concentration of lactic acid and postoperative outcome in children with congenital heart disease.Methods Sixty children with congenital heart diseases undergoing open heart surgery with ECC were randomly divided into three groups: groupⅠ(n=20) underwent mild hemodilution [Hb(80—90)g/L],groupⅡ(n=20) with medium hemodilution [Hb(70—79)g/L],and groupⅢ(n=20) with deep hemodilution [Hb(60—69)g/L].The concentration of lactic acid and PaO_2 in groupⅡ and group Ⅲ were compared with groupⅠ before ECC,during ECC,after ECC and 24h after the operation.The rate of homologous transfusion during ECC and the postoperative dosage of furosemide were also compared among the three groups.Results The concentrations of lactic acid and PaO2 in the three groups were all within normal range before ECC,during ECC,after ECC and 24h after operation.The homologous transfusion rate during ECC were lower in groupⅡ(30%)and groupⅢ(15%) compared to that of groupⅠ(50%)(P

Objective To explore the value of conventional and contrast‐enhanced ultrasound(CEUS) in the diagnosis of tumors in front of the orbit equator . Methods Clinical data included conventional ultrasound and CEUS image of 133 cases (156 eyes) with orbital lesions were analyzed retrospectively . All lesions were confirmed by surgical pathology or clinical cure ,which included 26 cases of cystic lesions (epidermoid cysts ,dermoid cysts ,sebaceous cysts and mucous cysts) ,29 cases (30 eyes) of orbital hemangioma ,13 cases ( 16 eyes ) of inflammatory pseudotumor ,11 cases of lacrimal gland pleomorphic adenoma ,3 cases (5 eyes) of lymphoepithelial lesion ,36 cases (53 eyes) of malignant lymphoma ,5 cases of meibomian gland carcinoma ,4 cases of lacrimal gland adenoid cystic carcinoma ,3 cases of malignant melanoma and 3 cases of basal cell carcinoma . Results CEUS of benign cystic lesions showed the tumors were enhanced inhomogenously . Most CEUS of benign tumours displayed?slow in and slow out ,and high enhancement when reached the peak but the size of images had no change . While CEUS of malignant tumours showed?fast in and fast out ,homogeneous or inhomogeneous high enhancement and ill‐defined or irregular shape ,and volume increased compared to two‐dimensional ultrasound when reached the peak .Some other former district orbital lesions ,such as cystic lesion ,cavernous hemangioma ,pleomorphic adenoma and malignant lymphoma ,had their own ultrasound features . Conclusions CEUS combines with conventional ultrasound may contribute to the qualitative diagnosis of tumors in front of the orbit equator .

Objective To provide reference for CT performance/quality test. Methods Researches were made in Chinese documentations on CT performance/quality test issued from 1998-aug 2002.Results Approximately a quarter of CTs among the documents assembly released public were tested unqualified . Qualification rate of new CTs was higher Than second-handed ones. Part of items and data in the documentations were insufficient. Conclusion CT performance/quality test is a crucial part of system Engineering of QC(quality control),therefore it must be implemented seriously and relevant regulations should be optimized in order to benefit both patients and health-care communities.

Background:Intestinal Beh?et's disease is a subtype of multisystem vasculitis that affects the intestine,leading to severe intestinal and extra-intestinal complications,increased hospitalization rate,and a decrease in the quality of life of patients.Aims:To analyze the clinical,endoscopic,and pathological characteristics of patients with intestinal Beh?et's disease.Methods:Twenty-five patients with intestinal Beh?et's disease admitted from April 2018 to April 2023 at Tongji Hospital,Tongji Medical College of Huazhong University of Science and Technology were enrolled.The demographic data,clinical symptoms and signs,endoscopic findings,laboratory results,and therapeutic strategies were retrospectively analyzed.Results:In 25 patients with intestinal Beh?et's disease enrolled in this study,12 were males and 13 females,with a median age of onset at 37 years old.Oral ulcer was reported in 72.0%of patients,with 60.0%presenting with oral ulcer as the initial manifestation.Before diagnosis,60.0%of patients suffered from abdominal pain,and 12.0%experienced retrosternal pain or discomfort.All patients presented with ileocecal ulcer under endoscopy,with 15 cases of typical ulcer and 10 cases of atypical ulcer.The difference in gender distribution was statistically significant between the two groups(P=0.041 4).The disease activity index for intestinal Beh?et's disease(DAIBD)in typical ulcer group was significantly higher than that in atypical ulcer group(P=0.019 4),while no significant differences in neutrophil count,hemoglobin,hypersensitive C-reactive protein,and γ-glutamyl transferase were found between the two groups(P>0.05).Five patients were accompanied with esophageal ulcer.During the course of the disease,5 patients escalated to biological therapy(adalimumab or infliximab).Four patients with typical ulcer underwent surgical treatment due to complications such as intestinal perforation,gastrointestinal bleeding,and anal fistula.Conclusions:There exists a significant association between gender,DAIBD score and typical ileocecal ulcer in patients with intestinal Beh?et's disease.

Objective This paper aims to investigate and analyze the baseline conformity rate of bacterial culture exami-nation records in a tertiary specialized hospital.By doing this,this paper seeks to understand the current situation of medical re-cord writing of bacterial culture examination and explore the improvement path and relevant measures for enhancing the conformity rate of bacterial culture examination records.Methods According to the requirements of"Quality Control Index of Medical Re-cord Management(2021 Edition)",a retrospective analysis was conducted on 6 317 medical records that underwent bacterial culture examination in 2022.Results The execution rate of medical orders was 100.00％,the completeness rate of the report sheet was 100.00％,the record rate of medical records was 81.05％,the analysis rate of results was 33.07％,and the conformi-ty rate of bacterial culture examination records was 33.07％.Conclusion It is imperative to enhance the conformity rate of bac-terial culture examination records and improve the quality of medical records in terms of content.
