Effectiveness and safety of ultrasound-guided hydrostatic reduction for children with acute intussusception.

OBJECTIVE: This study aims to explore the effectiveness and safety of the new-type ultrasound-guided hydrostatic reduction for children with acute intussusception. METHODS: The clinical data of 364 children with primary acute intussusception who underwent nonsurgical reduction in our hospital between January 2016 and May 2019 were retrospectively analyzed. Among the 364 children, 119 formed the hydrostatic reduction group. There were 89 males and 30 females, and the average age of admission was 25.13 ± 1.43 months. Among the pneumatic reduction group of 245 patients, there were 163 males and 82 females. The average age of admission was 22.47 ± 1.52 months. The reduction rate, length of stay, and perforation rate were compared between the two groups. RESULTS: Univariate analysis showed that the reduction rate in the hydrostatic group (94.96%) was higher than in the pneumatic group (85.31%) (p = 0.007), and the hospital stay (2.76 ± 0.15 days) of the hydrostatic reduction group was shorter than that of the pneumatic reduction group (3.56 ± 0.35 days) (p = 0.038). In children with intussusception time >48 h, the reduction rate was 95.45% in the hydrostatic reduction group and 86.20% in the pneumatic reduction group. CONCLUSION: The new-type ultrasound-guided hydrostatic reduction has a higher reduction rate in the treatment of acute intussusception in children results in a shortened hospital stay, It is effective, safe, and avoids radiation exposure.

Solanum muricatum Ameliorates the Symptoms of Osteogenesis Imperfecta In Vivo.

Pepino (Solanum muricatum), which is an evergreen plant native to South America, is well-known for its effects in antioxidation, antidiabetic activity, anti-inflammation, and antitumor activity. A previous study in our lab indicated that Solanum muricatum (SM) extract promoted osteogenic differentiation by upregulating Wnt and BMP signaling pathway in rat bone marrow stromal cells. The osteogenesis imperfecta (OI) mouse model was used in order to further discover the osteogenic properties of SM extract in the present research. We utilized microCT analysis to collect bone mass and microarchitectural parameters at vertebrae and at femur metaphysis in OI mice. Raman spectrometry was applied to identify change of bone mineral and matrix composition during SM treatment. Finally, collagen synthesis marker PINP and collagen degradation marker CTX were detected using enzyme immunoassay. SM extract could improve the bone mass and microarchitectural parameters both at vertebrae and at femur metaphysis. It also significantly increased the collagen content by promoting its biosynthesis and inhibiting its degradation. By using heterozygous Col1a1Jrt /+ mice as a model of OI, 6 weeks treatment of SM extract could significantly ameliorate the symptoms in OI mice. Thus, SM holds potential for developing new drugs of bone formation and bone remodeling.

Albumin Supplement Affects the Metabolism and Metabolism-Related Drug-Drug Interaction of Fenoprofen Enantiomers.

The influence of albumin towards the metabolism behavior of fenoprofen enantiomers and relevant drug-drug interaction was investigated in the present study. The metabolic behavior of fenoprofen enantiomers was compared in a phase II metabolic incubation system with and without bovine serum albumin (BSA). BSA supplement increased the binding affinity parameter (Km) of (R)-fenoprofen towards human liver microsomes (HLMs) from 148.3 to 214.4 µM. In contrast, BSA supplement decreased the Km of (S)-fenoprofen towards HLMs from 218.2 to 123.5 µM. For maximum reaction velocity (Vmax), the addition of BSA increased the Vmax of (R)-fenoprofen from 1.3 to 1.6 nmol/min/mg protein. In the contrast, BSA supplement decreased the Vmax value from 3.3 to 1.5 nmol/min/mg protein. Andrographolide-fenoprofen interaction was used as an example to investigate the influence of BSA supplement towards fenoprofen-relevant drug-drug interaction. The addition of 0.2% BSA in the incubation system significantly decreased the inhibition potential of andrographolide towards (R)-fenoprofen metabolism (P < 0.001). Different from (R)-fenoprofen, the addition of BSA significantly increased the inhibition potential of andrographolide towards the metabolism of (S)-fenoprofen. BSA supplement also changed the inhibition kinetic type and parameter of andrographolide towards the metabolism of (S)-fenoprofen. In conclusion, albumin supplement changes the metabolic behavior of fenoprofen enantiomers and the fenoprofen-andrographolide interaction.
