Objective:To analyze the diagnostic value of bedside capsule endoscopy in patients with acute or severe gastrointestinal bleeding.Methods:Clinical data from patients who underwent bedside capsule endoscopy due to acute or severe suspected gastrointestinal bleeding in Nanfang Hospital, Southern Medical University from June 2018 to September 2021 were analyzed retrospectively. The efficacy of capsule endoscopy in detecting upper gastrointestinal tract and small intestinal bleeding was evaluated.Results:A total of 74 patients underwent bedside capsule endoscopy for suspected acute or severe gastrointestinal bleeding. Five patients were excluded due to failure of examination due to retention of capsule endoscope in the gastric lumen, and 69 were included in the study, of whom 54 patients with a definitive diagnosis of gastrointestinal hemorrhage. The positive detection rate of the capsule endoscopy was 83.33% (45/54), including 17 cases of ulcer, 5 cases of erosion, 5 cases of vascular malformation, 4 protrusion mass, 4 diverticulum, 5 obscure gastrointestinal bleeding, 1 stenosis , 1 active mucosal blood exudation, 1 gastric retention, 1 mucosal swelling, and 1 mucosal wrinkle change. The sensitivity and specificity of capsule endoscopy in the diagnosis of upper gastrointestinal bleeding were 92.31% (12/13) and 75.00% (3/4) respectively. The sensitivity and specificity of capsule endoscopy for diagnosing small intestinal bleeding were 80.49% (33/41) and 90.91% (10/11) respectively.Conclusion:Bedside capsule endoscopy demonstrates high sensitivity and specificity in the diagnosis of gastrointestinal bleeding, showing potential advantages in bedside applications for acute and severe gastrointestinal bleeding.

Antipyretic-analgesics are currently one of the most prescribed drugs in children.The clinical application of antipyretic-analgesics for children in our country still have irrational phenomenon, which affects the therapeutic effect and even poses hidden dangers to the safety of children.In this paper, suggestions were put forward from the indications, dosage form/route, dosage suitability, pathophysiological characteristics of children with individual differences and drug interactions in the symptomatic treatment of febrile children, so as to provide reference for the general pharmacists when conducting prescription review.

Anaphylaxis is increasingly in children, which is currently undernotified, underdiagnosed, and undertreated in China.In order to further improved the understanding and management of anaphylaxis, this issue reviews the pathogenesis, triggers and risk factors, clinical diagnosis and management of anaphylaxis, thus offers the recommedations of anaphylaxis in Chinese children based on previous published evidence-based guidelines and practice parameters.Recommendation aims to develop guiding principles for the diagnosis and management of anaphylaxis in children, and provide a framework for the development of new guidelines.

Objective To investigate the expression of periostin in the kidneys of rats with obstructive nephropathy and its relevance to renal interstitial fibrosis.Methods Eighteen male adult SD rats were randomly divided into sham group,model group and benazepril group (6 in each group).Unilateral ureteral obstruction (UUO) model was induced by ligating the left ureter of rats.RT-PCR was used to detect the mRNA expressions of periostin and TGF-β1,and ELISA to detect the protein expression of periostin,Ang Ⅱ,and TGF-β1 in kidney tissue.Pathological changes of renal tissue were observed by HE and Masson staining.The protein expression of collagen Ⅰ (Col Ⅰ ) in kidney tissue was examined by immunohistochemical staining.Results The mRNA expressions of periostin and TGF-β1 in model group increased markedly as compared with sham group (all P＜0.05),and benazepril could decrease these mRNA expressions (all P＜0.05).The protein expressions of periostin,Ang Ⅱ and TGF-β1 in kidney tissue were significantly increased in model group as compared with sham group (all P＜0.05),and benazepril could decrease these protein expressions (all P＜0.05).The expression of periostin in kidney tissue was positively correlated with the expressions of Ang Ⅱ,TGF-β1 and Col Ⅰ,as well as the degree of renal interstitial fibrosis (r=0.652,0.781,0.776 and 0.825 respectively,all P ＜0.05).Conclusion Periostin expression is up-regulated in kidney tissue of rats with obstructive nephropathy,which is associated to the over-deposition of extracellular matrix (ECM) in the kidneys of UUO rats.

Objective To test the scientificity, practicability, feasibility, intelligibility, and acceptability of the Primary-Level Personnel Guiding Handbook for Schistosomiasis Control(probationary edition). Methods Twenty-seven county and village doctors were selected randomly from two schistosomiasis transmission uncontrolled counties in Jiangxi Province as pretest objects. The pretest was carried out with the focus group discussion. Results The proportions of pretest objects who considered handbook had scientificity, practicability, feasibility, intelligibility and acceptability were 59.26%, 85.19%,55.56%,51.85% and 92.59%, respectively, and the pretest objects had proposals and suggestions for modification. Conclusion According to the suggestion and proposal from the pretest objects, the handbook can be modified and published.
