Risk factors and a prediction model of severe asparaginase-associated pancreatitis in children.

We aimed to investigate whether early clinical indicators were associated with eventual disease severity, and to develop a predictive model for severe asparaginase-associated pancreatitis (AAP). Seventy-five acute lymphoblastic leukaemia (ALL) cases with AAP admitted to Shanghai Children's Medical Center from March 2013 to August 2023 were divided into non-severe (n = 44) and severe (n = 31) groups based on Atlanta diagnostic and AAP grading criteria. We compared essential information, asparaginase(ASP) dosage form, cumulative dose, clinical characteristics and laboratory tests between the groups.

Clinical manifestations, laboratory indicators, genetic testing results and imaging findings including MRCP were collected.

Resveratrol Prevents Skeletal Muscle Atrophy and Senescence via Regulation of Histone Deacetylase 2 in Cigarette Smoke-Induced Mice with Emphysema.

Objective: The aim of this study was to investigate the effects of resveratrol (RSV) on cigarette smoke (CS)-induced skeletal muscle atrophy and senescence in mice with emphysema and to explore the underlying mechanisms.

Methods: Gastrocnemius muscle weight and lung and muscular morphology were observed in CS-exposed mice with or without RSV treatment. The expression of atrophy-related markers (MURF1 and MAFbx), senescence-related markers (P53, P21 and SMP30) and NF-κB inflammatory pathways was detected by Western blotting and real-time PCR.

Roles of Nicotinamide N-Methyltransferase in Obesity and Type 2 Diabetes.

Type 2 diabetes (T2D) is thought to be a complication of metabolic syndrome caused by disorders of energy utilization and storage and characterized by insulin resistance or deficiency of insulin secretion. Though the mechanism linking obesity to the development of T2D is complex and unintelligible, it is known that abnormal lipid metabolism and adipose tissue accumulation possibly play important roles in this process. Recently, nicotinamide N-methyltransferase (NNMT) has been emerging as a new mechanism-of-action target in treating obesity and associated T2D.

Methods: One hundred ninety-four H. pylori positive children were randomized in two groups.

Health effects from swimming training in chlorinated pools and the corresponding metabolic stress pathways.

Chlorination is the most popular method for disinfecting swimming pool water; however, although pathogens are being killed, many toxic compounds, called disinfection by-products (DBPs), are formed. Numerous epidemiological publications have associated the chlorination of pools with dysfunctions of the respiratory system and with some other diseases. However, the findings concerning these associations are not always consistent and have not been confirmed by toxicological studies.

[Distribution and schistosomiasis transmission risks of Biomphalaria straminea in inland China].

Biomphalaria straminea, the intermediary host of Schistosoma mansoni, was found by survey in local areas of Shenzhen City in 1981, which was the first finding of the snail in inland China. By 2013, the snail had spread in large range of Shenzhen City and overspread to the surrounding regions, Dongguan City and Huizhou City. Due to the facts that Shenzhen City has many international communications and is a key area of labor export, with high population mobility, while the reports of S.

ROC curves were used to evaluate the sensitivity, specificity, positive and predictive values and optimal cut-off.

Diagnosis and treatment of blue rubber bleb nevus syndrome in children.

Background: Blue rubber bleb nevus syndrome (BRBNS) is characterized by distinctive vascular malformations of skin and the gastrointestinal tract, often leading to chronic anemia and intestinal bleeding.

[Application of metal hemoclip for endoscopic polypectomy in children with thick-pedunculated intestinal polyps].

Objective: With the development of endoscopic therapy in children, endoscopic electrocoagulation polypectomy had gradually replaced surgery and became an important method to resect gastrointestinal polyps in children. Simple electrocoagulation polypectomy could often bring some complications of gastrointestinal bleeding and perforation because of incomplete electrocoagulation or mechanical incision, especially in gastrointestinal thick-pedunculated polyps which always have thick nutrient blood vessel. Hemoclips can successfully interdict arteriovenous blood because it can clamp tissue firmly without causing necrosis around the target area.
