Development and validation of a preoperative model for predicting positive proximal margins in adenocarcinoma of the esophagogastric junction and assessing safe margin distance.

Objective: To develop and validate a model for preoperative prediction of positive proximal margins for adenocarcinoma of the esophagogastric junction (AEG) by transabdominal approach, and to analyze the safe margin distances for patients with different risks of positive proximal margins.

Materials And Methods: A retrospective analysis was performed on 284 AEG patients who underwent surgery via the transabdominal approach at Hengshui People's Hospital between January 2017 and December 2023. Patients were divided into a training set (=201, first five years) and a test set (=83, last two years).

Application of intra-abdominal pressure monitoring in early enteral nutrition after abdominal surgery.

Objective: To explore the effect of intra-abdominal pressure monitoring in early enteral nutrition therapy after abdominal surgery.

Methods: 164 patients who underwent elective abdominal surgery in our hospital from January 2019 to January 2020 were selected and divided into an observation group and a control group according to the random number table method, with 82 cases in each group. On the basis of conventional enteral nutrition nursing, the control group received conventional gastric residual monitoring, and the observation group received intra-abdominal pressure monitoring.

The applied research on the intra-abdominal pressure monitoring in early enteral nutrition in patients with severe pneumonia.

Objective: To explore the applied value of intra-abdominal pressure (IAP) monitoring in early enteral nutrition (EEN) in patients with severe pneumonia.

Methods: 96 patients with severe pneumonia who underwent EEN treatment in our hospital from June 2017 to June 2019 were selected. According to the random number table method, they were divided into a control group (48 patients) and an observation group (48 patients).

Temperature regulates circadian rhythms of immune responses in red swamp crayfish Procambarus clarkii.

As an ectothermic animal, crayfish immunity and their resistance to pathogen can be significantly affected by environmental factors such as light and temperature. It has been found for a long time that multiple immune parameters of animals and human are circadian-regulated by light-entrained circadian rhythm. Whether temperature also affects the immune rhythm of animals still remains unclear.

Subulura halli (Ascaridida: Subuluridae) from the endangered great bustard Otis tarda Linnaeus (Aves: Gruiformes) in China.

Subulurid nematodes identified as Subulura halli Barreto, 1918 were collected from the endangered bird Otis tarda Linnaeus (Gruiformes: Otididae) in China. A detailed redescription of the hitherto poorly known species is presented using both light and, for the first time, scanning electron microscopy. Previously unreported and erroneous morphological features of taxonomic significance are revealed.

Morphological variability and molecular characterisation of Dichelyne (Cucullanellus) pleuronectidis (Yamaguti, 1935) (Ascaridida: Cucullanidae) from the flatfish Pleuronichthys cornutus (Temminck & Schlegel) (Pleuronectiformes: Pleuronectidae) in the East China Sea.

Cucullanid nematodes identified morphologically as Dichelyne (Cucullanellus) pleuronectidis (Yamaguti, 1935) were collected from the ridged-eye flounder Pleuronichthys cornutus (Temminck & Schlegel) (Pleuronectiformes: Pleuronectidae) in the East China Sea. Their examination using light microscopy and, for the first time, scanning electron microscopy, revealed several important, but previously unreported morphological features and the presence of remarkable morphological differences in the intestinal caecum and deirids among some individuals. Consequently, specimens of D.
