This study aimed to assess the effects of non-surgical periodontal treatment (NSPT) of chronic periodontitis on insulin sensitivity, glucose tolerance, and serum C reactive protein (CRP) level in individuals without diabetes. Twenty individuals without diabetes with chronic periodontitis underwent NSPT, which consisted of complete scaling, polishing, root planing, and irrigation of the periodontal pockets with a 10% povidone-iodine solution. Periodontal indices (plaque index, gingival bleeding index, pocket depth, and clinical attachment loss), insulin sensitivity using the Short Insulin Tolerance Test index (KITT), glucose tolerance derived from oral glucose tolerance test, and serum CRP level were measured before and 3 months after the intervention. ⋯ There was a trend toward improvement in glucose tolerance, although not statistically significant after the intervention. This study suggests that NSPT of chronic periodontitis in individuals without diabetes is associated with increased insulin sensitivity and decreased serum CRP levels. Trial registration number NCT02830113.

Among immunologically normal hosts, patients with chronic obstructive pulmonary disease (COPD) are considered to be at high risk of invasive pulmonary aspergillosis (IPA), and early diagnosis and treatment are the key to improving the prognosis of patients. Here we aimed to evaluate whether interleukin (IL)-6 and IL-8 might be used in the detection and diagnosis of IPA in patients with COPD. We prospectively collected 106 patients with COPD and divided them into non-IPA (n=74), probable/possible IPA (n=26) and proven IPA (n=6). ⋯ The sensitivity and specificity of IL-6 for diagnosing IPA were 74.32% and 81.25% (cut-off at 92.82 pg/mL, area under the curve (AUC)=0.8366) in serum and 68.92% and 71.88% (cut-off at 229.4 pg/mL, AUC=0.7694) in BALF. The sensitivity and specificity of IL-8 for diagnosing IPA were 83.78% and 81.25% (cut-off at 93.46 pg/mL, AUC=0.8756) in serum and 85.14% and 75.00% (cut-off at 325.4 pg/mL, AUC=0.8252) in BALF. The elevated levels of IL-6 and IL-8 in patients with IPA with COPD could be used as auxiliary indicators to diagnose IPA in addition to galactomannan.

This study aimed to explore the protective effect of Shenfu on the hemodynamics and gut integrity in a porcine model of hemorrhagic shock. Hemorrhagic shock was induced in 32 domestic pigs with a rapid bleeding via the arterial sheath to a mean arterial pressure of 40 mm Hg within 10 min. Animals with hemorrhagic shock were then randomly assigned into the negative control group (n=8), receiving neither blood transfusion nor drug treatment; the blood transfusion group, in which animals were given blood transfusion alone; the saline group, in which animals were blood transfused and resuscitated with saline (3 mL/kg); and the Shenfu group, in which animals received blood transfusion and resuscitation with Shenfu (3 mL/kg). ⋯ Notably, treatment with Shenfu suppressed oxidative stress markers MDA, MPO, and FABP2 in the intestine. Oppositely, SOD, Na+/K+-ATPase and Ca++ATPase levels in intestinal tissues were promoted by Shenfu treatment. Shenfu demonstrates significant protective effect on the hemodynamics and gut epithelium of pigs with hemorrhagic shock.
