RESUMO
Inflammatory bowel disease (IBD) encompasses a collection of idiopathic diseases characterized by chronic inflammation in the gastrointestinal (GI) tract. Patients diagnosed with IBD often experience necessitate long-term pharmacological interventions. Among the multitude of administration routes available for treating IBD, oral administration has gained significant popularity owing to its convenience and widespread utilization. In recent years, there has been extensive evaluation of the efficacy of orally administered herbal medicinal products and their extracts as a means of treating IBD. Consequently, substantial evidence has emerged, supporting their effectiveness in IBD treatment. This review aimed to provide a comprehensive summary of recent studies evaluating the effects of herbal medicinal products in the treatment of IBD. We delved into the regulatory role of these products in modulating immunity and maintaining the integrity of the intestinal epithelial barrier. Additionally, we examined their impact on antioxidant activity, anti-inflammatory properties, and the modulation of intestinal flora. By exploring these aspects, we aimed to emphasize the significant advantages associated with the use of oral herbal medicinal products in the treatment of IBD. Of particular note, this review introduced the concept of herbal plant-derived exosome-like nanoparticles (PDENs) as the active ingredient in herbal medicinal products for the treatment of IBD. The inclusion of PDENs offers distinct advantages, including enhanced tissue penetration and improved physical and chemical stability. These unique attributes not only demonstrate the potential of PDENs but also pave the way for the modernization of herbal medicinal products in IBD treatment.

RESUMO
OBJECTIVE: To observe changes of [Ca2+]i concentration and CaM, CaMK II and p-CaMK II of Ca2+/CaMK II signaling pathways in skeletal muscle tissue of rats with spleen-qi deficiency and intervention of Sijunzi decoction and extract of Hedysarum polybotrys. METHODS: Rats were randomized into four groups: normal control group, spleen-qi deficient model group, extract from Hedysarum polybotrys group and Sijunzi decoction group, ten rats in each group. After the spleen-qi deficient models were built by comprehensive application of rhubarb, exhaustive and hungry methods, and treatment groups were treated with extract from Hedysarum polybotrys at 6 g/(kg . d) or Sijunzi decoction at 20 g/(kg . d) for 21 d. Then, general existence,gastrointestinal hormones GAS and MOT levels, and activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase of skeletal muscle were evaluated. Also, confocal laser technology was used to test cellular[Ca2+]i concentrations in skeletal muscle and Western blotting technique was used to test CaM, CaMK II and p-CaMK 11 expression in intestinal tissue of spleen-qi deficient model rats. RESULTS: Compared with normal group, general condition was poor, levels of GAS and MOT decreased (P <0. 01), activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase, [Ca2+]i concentration as well as expression of CaM, CaMK II and p-CaMK II in skeletal muscle decreased significantly (P < 0. 01) in spleen-qi deficienct model rats. Compared with model group, general condition improved significantly, as well as level of MOT in intestinal increased (P <0. 05) in the rats of extract from Hedysarum polybotrys group and Sijunzi decoction group,while level of GAS increased in intestinal(P <0. 05) in the rats of Sijunzi decoction group; Moreover, activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase as well as [Ca2+]i concentration and expression of CaM and CaMK II in skeletal muscle tissue increased (P < 0. 05) in the rats of extract from Hedysarum polybotrys group and Sijunzi decoction group, while p-CaMK II in skeletal muscle tissue increased in the rats of Sijunzi decoction group (P < 0. 05). CONCLUSION: Sijunzi decoction and extract of Hedysarum polybotrys can be applied to treat spleen-qi deficiency syndrome through the mechanism of regulating GAS and MOT secretion and raising expression of Ca2+ /CaM signaling pathways key factors in skeletal muscle tissue. Sijunzi decoction has the better effect

Anticholinesterase pesticides have been widely used in agricultural and domestic settings and can be detected in the environment after long-term use. Although the acute toxic effects of chlorpyrifos and carbaryl have been well described, little is known about the chronic toxicity of the pesticides mixture. To investigate their chronic neurotoxicity, Wistar rats were exposed to chlorpyrifos, carbaryl, and their mixture (MIX) for 90 consecutive days. The activities of serum cholinesterase (ChE) as well as acetylcholinesterase (AChE) and neuropathy target esterase (NTE) in nerve tissues were determined. Furthermore, the histopathological examination was carried out. The results showed that ChE activity significantly decreased in all treated rats except the rats treated with low dose carbaryl. Treatment with middle- and high-dose chlorpyrifos and MIX in rats significantly inhibited AChE activity in the central nervous tissues, whereas treatment with carbaryl alone did not. In sciatic nerve, AChE activity was significantly inhibited by high-dose carbaryl and MIX, but not by chlorpyrifos alone. No significant NTE inhibition was observed in all treatment groups. Histopathological examination revealed that both chlorpyrifos and MIX treatment induced hippocampal damage. However, no obvious hippocampal damage was found in carbaryl-treated rats. Carbaryl and MIX, but not chlorpyrifos alone, induced pathological damage of sciatic nerve. Taken together, all of the results indicated that chlorpyrifos and carbaryl have different toxicological target tissues in nervous system and showed corresponding effects in the nervous tissues, which may reflect the different sensitivity of central and peripheral nervous tissues to different pesticides individually and in combination.

Metabolic profiling of urine from pesticide-treated rats was investigated by the nuclear magnetic resonance (NMR)-based metabonomic strategy. Twenty-four-hour urine samples of rats were collected after administration with propoxur at doses of 0.85, 1.70, and 8.51 mg/kg, respectively, for 28 consecutive days. Liver tissue was fixed and the histopathological alterations were examined. The results showed that propoxur at high dose induced liver histopathological injury. Metabonomic analysis demonstrated that the levels of creatine and taurine markedly increased together with slight elevation of hippurate, glucose, and amino acids in low- and medium-dose groups. However, concentrations of urinary lactate, acetate, acetone, succinate, citrate, and 2-oxoglutarate increased in high-dose group. All these results suggested that propoxur could inhibit liver function through altering the energy and lipid metabolism. These data also supported the contention that the NMR-based metabonomic approach represents a promising new technology for the development of pesticide toxicity screening and mechanism exploration.

Chlorpyrifos (CPF) and carbaryl (CAR) have been widely used in agricultural and domestic settings. Previous studies have demonstrated that CPF and CAR are generally neurotoxic to mammals, whereas the toxicities of these pesticides to other organs and their potential interactive effects remain unclear. The purpose of this study assessed the alterations of histopathology, biochemical parameters, and metabolic profiles of serum in rats following the treatment with CPF and CAR alone or in combination. No histopathological changes were observed in the liver and kidney tissues. Biochemical analysis of blood showed that alanine aminotransferase and total bilirubin in serum increased slightly in CPF-treated rats as compared to controls. Metabonomic analysis revealed alternations in a number of metabolites involving the metabolism of glucose, free fatty acids, and amino acids in liver mitochondria. The treatment of rats with CPF alone resulted in a decrease in lactate, low- and very low-density lipoprotein (LDL/VLDL), dimethylglycine (DMG), and aspartate. This was accompanied by an increase in isoleucine and leucine, 3-hydroxybutyrate (3-HB), N-acetylglycoprotein (NAC), acetone, succinate, glutamine, choline, creatine, glucose, and amino acids in a dose-dependent manner. Similarly, treatment with a high dose of CAR alone led to a decrease in DMG, aspartate, LDL/VLDL, and dimethylamine and an increase in taurine, glucose, and amino acids. The levels of lactate and LDL/VLDL decreased, while those of 3-HB, NAC, acetone, succinate, and glutamine elevated in the group of rats treated with a mixture of CPF and CAR as compared to the groups of CPF or CAR alone. Our results suggest that subchronic exposure to CPF and CAR alone, or in combination, could cause a disturbance in energy and fatty acid metabolism in the liver mitochondria of rats. Overall, we have shown that analysis of metabolic profiles can make exceptional contributions to the understanding of the individual or mutual effects following exposure to a low dose of pesticides.
