March Extract in the Treatment of Obesity Induced by High-Calorie Diet. BIOLOGY 2024; 13:535. [PMID: 39056728 PMCID: PMC11274057 DOI: 10.3390/biology13070535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Revised: 06/22/2024] [Accepted: 07/12/2024] [Indexed: 07/28/2024]
Abstract
Obesity, a chronic disease, resulted from excessive consumption of high-calorie foods, leading to an energy imbalance. Protium heptaphyllum (P. heptaphyllum) was used in folk medicine for its analgesic, anti-inflammatory, and healing properties. The association of the extract from P. heptaphyllum with nanotechnology was innovative for combining high technology with active ingredients that are easily accessible in the Amazon region. This study evaluated the effect of liposomes containing the ethyl acetate fraction of the crude extract of P. heptaphyllum leaves on obesity. Male Wistar rats treated with a high-calorie diet for 8 weeks to induce obesity received treatment with the liposome formulation containing P. heptaphyllum extract (1 mg/kg/day, via gavage) for 14 days. Morphological, metabolic, redox status, immunological, and histological parameters were evaluated in the adipose and liver tissue of the animals. The groups were divided as follows: C: control; P: liposomes containing extract; O: obese, and OP: obese + liposomes containing extract. The obesity model resulted in increases in body weight, caloric intake, body fat weight, and in the lipid profile. In adipose tissue, P decreased SOD (superoxide dismutase) activity in obese animals. In the liver, a positive modulation of the extract was observed in relation to glucose, amino acids, lactate, hepatoprotective action, and anti-inflammatory activity, with a decrease in interleukin 1β (IL-1β) in obese animals. The results showed an improvement in the functional and inflammatory aspects, but the treatment was not effective in alleviating general changes related to obesity, such as weight gain, fat, glucose, triglycerides, and inflammation in adipose tissue, highlighting the complexity of responses in different organs during obesity and treatment with P. heptaphyllum.

Hepatobiliary Pancreat Dis Int 2024; 23:300-309. [PMID: 38057185 DOI: 10.1016/j.hbpd.2023.11.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Accepted: 11/17/2023] [Indexed: 12/08/2023]
Abstract
BACKGROUND Visceral adipose tissue (VAT) has been linked to the severe acute pancreatitis (SAP) prognosis, although the underlying mechanism remains unclear. It has been reported that pyroptosis worsens SAP. The present study aimed to verify whether mesenteric adipose tissue (MAT, a component of VAT) can cause secondary intestinal injury through the pyroptotic pathway. METHODS Thirty-six male Sprague Dawley (SD) rats were divided into six different groups. Twelve rats were randomly divided into the SAP and control groups. We monitored the changes of MAT and B lymphocytes infiltration in MAT of SAP rats. Twelve SAP rats were injected with MAT B lymphocytes or phosphate buffer solution (PBS). The remaining twelve SAP rats were first injected with MAT B lymphocytes, and then with MCC950 (NLRP3 inhibitor) or PBS. We collected blood and tissue samples from pancreas, gut and MAT for analysis. RESULTS Compared to the control rats, the SAP group showed inflammation in MAT, including higher expression of tumor necrosis factor (TNF-α) and interleukin-6 (IL-6), lower expression of IL-10, and histological changes. Flow cytometry analysis revealed B lymphocytes infiltration in MAT but not T lymphocytes and macrophages. The SAP rats also exhibited intestinal injury, characterized by lower expression of zonula occludens-1 (ZO-1) and occludin, higher levels of lipopolysaccharide and diamine oxidase, and pathological changes. The expression of NLRP3 and n-GSDMD, which are responsible for pyroptosis, was increased in the intestine of SAP rats. The injection of MAT B lymphocytes into SAP rats exacerbated the inflammation in MAT. The upregulation of pyroptosis reduced tight junction in the intestine, which contributed to the SAP progression, including higher inflammatory indicators and worse histological changes. The administration of MCC950 to SAP + MAT B rats downregulated pyroptosis, which subsequently improved the intestinal barrier and ameliorated inflammatory response of SAP. CONCLUSIONS In SAP, MAT B lymphocytes aggravated local inflammation, and promoted the injury to the intestine through the enteric pyroptotic pathway.

Abstract
Background The epidemiological data on distribution of pediatric acute pancreatitis was deficiency. And the purpose of this research was to investigate the epidemiology and clinical features of pediatric acute pancreatitis in the population in north of Guizhou, China. Design and methods A retrospective case analysis was conducted to accomplish the aim. Patients who were under 18 years old with acute pancreatitis were recruited. Data were collected directly from Hospital Information System (HIS) after patients were discharged from the hospital. Results A total of 95 children aged from 3 to 17 years were collected, 49 patients were boys and 46 were girls. In addition, the percentage of acute pancreatitis occurring in girls aged 15-17 years was significantly higher than that of boys (54.3% vs 36.7%). Meanwhile, the percentage of severe patients over 12 years exceeded 90.0%. Moreover, the proportion of severe acute pancreatitis in girls was significantly higher than that in boys (26.1% vs 10.2%), and 64.7% of severe patients were from 12 to 14. What's more, more patients occurred in May, June, and December and on weekends, 47.1% (8/17) severe cases occurred in May, June, and July, and 47.1% (8/17) severe patients occurred on weekend. The length of hospitalization and hospitalization costs of severe patients were found higher compared to mild patients. Conclusions Higher risk of pediatric acute pancreatitis, especially severe acute pancreatitis, in north of Guizhou, China occurred on weekend, during May and June, and among children aged 12-17 years, especially girls. Additionally, severe acute pancreatitis was associated with higher hospitalization costs and longer hospitalization length.

Abstract
BACKGROUND Numerous studies have linked visceral adipose tissue (VAT) to gastrointestinal diseases. However, it remains unclear whether these associations reflect causal relationships. METHODS We used a two-sample Mendelian randomization (MR) approach to elucidate the causal effect of VAT on nine non-tumour gastrointestinal diseases. The inverse-variance weighted method was used to perform the MR analyses. Complementary and multivariable MR analyses were performed to confirm the results. RESULTS Genetically predicted higher VAT was associated with an increased risk of gastro-oesophageal reflux disease (GORD) (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.09-1.34; P = 3.06 × 10-4), duodenal ulcer (DU) (OR, 1.40; 95% CI, 1.10-1.77; P = 0.005), cholelithiasis (OR, 1.75; 95% CI, 1.53-2.00; P = 1.14 × 10-16), and non-alcoholic fatty liver disease (NAFLD) (OR, 2.68; 95% CI, 1.87-3.82; P = 6.26 × 10-8). There were suggestive associations between VAT and gastric ulcer (GU) (OR, 1.22; 95% CI, 1.01-1.48; P = 0.035) and acute pancreatitis (AP) (OR, 1.26; 95% CI, 1.05-1.52; P = 0.013). However, there was little evidence to support the associations between VAT and inflammatory bowel disease, irritable bowel syndrome, or chronic pancreatitis. The associations with GORD, GU, and NAFLD remained in the multivariable MR analyses with adjustment for body mass index (BMI). CONCLUSIONS This study provided evidence in support of causal associations between VAT and GORD, GU, DU, cholelithiasis, AP, and NAFLD. Moreover, the associations between GORD, GU, and NAFLD were independent of the effect of BMI.

Abstract
BACKGROUND Visceral adipose tissue (VAT) is related to SAP prognosis. As a depot of VAT, mesenteric adipose tissue (MAT) resides between pancreas and gut, which might affect SAP and the secondary intestinal injury. AIMS To investigate the changes of MAT in SAP. METHODS 24 SD rats were randomly divided into four groups. 18 rats in SAP group were euthanized in time gradients (6 h, 24 h, and 48 h after modeling) and the others in control group. Blood samples and tissues of pancreas, gut, and MAT were taken for analysis. RESULTS Compared to the control group, SAP rats appeared MAT inflammation, presenting higher mRNA expression of TNF-α and IL-6 and lower IL-10, and histological changes after 6 h of modeling, which became worse over time. Flow cytometry showed that B lymphocytes increased in MAT after 24 h of SAP modeling and lasted up to 48 h, earlier than the changes of T lymphocytes and macrophages. The intestinal barrier integrity was damaged after 6 h of modeling, presenting lower mRNA and protein expression of ZO-1 and occludin, higher serum levels of LPS and DAO, with pathological changes, which gradually aggravated after 24 h and 48 h. SAP rats had higher serum levels of inflammatory indicators and revealed histological inflammation of pancreas, the severity of which increased with the passage of modeling time. CONCLUSION MAT appeared inflammation in early-stage SAP, and became worse over time, with the same trend as the intestinal barrier injury and the severity of pancreatitis. B lymphocytes infiltrated early in MAT, which might promote the MAT inflammation.

Abstract
PURPOSE OF REVIEW Approximately 20-30% of children who experience one episode of acute pancreatitis will have at least one additional episode. For some children, pancreatitis recurs multiple times and in a few years is followed by the diagnosis of chronic pancreatitis. Identifying risk factors for recurrent episodes and disease progression is critical to developing therapeutic interventions. RECENT FINDINGS Obesity is driving an increase in biliary stone disease and severe acute pancreatitis. Recurrent acute pancreatitis (RAP) may lead to the development of diabetes through autoimmune mechanisms. Cystic fibrosis or CFTR-related disorders may present as RAP and CFTR modulator therapy can increase or decrease the risk of acute pancreatitis in these populations. Children with Crohn disease have a three-fold risk of acute pancreatitis over the general population while children with ulcerative colitis are at increased risk for pediatric autoimmune pancreatitis, a disorder that may be distinct from autoimmune pancreatitis described in adults. Obstructive jaundice in the absence of identified mechanical factors may be a presenting sign of pediatric autoimmune pancreatitis. SUMMARY Pediatric RAP is a painful condition that leads to gland destruction and functional insufficiency. Risk factors are being clarified but preventive treatments remain elusive.
