Establishment of models to predict factors influencing periodontitis in patients with type 2 diabetes mellitus.

Background: Type 2 diabetes mellitus (T2DM) is associated with periodontitis. Currently, there are few studies proposing predictive models for periodontitis in patients with T2DM.

Aim: To determine the factors influencing periodontitis in patients with T2DM by constructing logistic regression and random forest models.

Influence of dexamethasone on mesenteric lymph node of rats with severe acute pancreatitis.

Aim: To study the influence and mechanisms of dexamethasone on mesenteric lymph node of rats with severe acute pancreatitis (SAP).

Methods: The SAP rats were assigned to model, treated or sham-operated groups. The mortality, pathological changes of mesenteric lymph nodes, expression levels of NF-kappa B, P-selectin, Bax, Bcl-2 and caspase-3 protein and changes in apoptotic indexes in lymph nodes were observed at 3, 6 and 12 h after operation.

Application of tissue microarrays to study the influence of dexamethasone on NF-kappaB expression of pancreas in rat with severe acute pancreatitis.

To discuss the influence of dexamethasone on NF-kappaB expression of pancreas in rat with severe acute pancreatitis (SAP). Ninety rat SAP models were divided into the model group and dexamethasone treatment group with 45 rats in each group; another healthy 45 rats were selected to be the sham operation group. The groups were divided into the 3, 6 and 12 h group with 15 rats in each group.
