METHOD FOR TREATING PANCREATITISTECHNICAL FIELD
[0001] The present disclosure relates to the treatment of pancreatitis, including acute pancreatitis (AP) , in particular severe acute pancreatitis (SAP) , and chronic pancreatitis, as well as the corresponding clinical symptoms and complications, such as intestinal injury, edema, hemorrhage, and necrosis from mild to severe, systemic inflammatory response syndrome (SIRS) , multiple organ dysfunction syndromes (MODS) , including acute respiratory failure, acute kidney failure, acute liver failure, comprising administrating to the subject in need thereof an effective amount of a NLRP3 inflammasome inhibitor.BACKGROUND
[0002] Pancreatitis is a non-infectious inflammatory disease, which is mainly classified into acute pancreatitis (AP) and chronic pancreatitis (CP) .
[0003] Acute pancreatitis (AP) is a sudden inflammatory injury caused by the digestion of pancreatic tissue by its own pancreatic juice due to various factors (increased pancreatic duct pressure, rupture of pancreatic cells, leakage of a large amount of functional digestive enzymes in the cells, "digesting"the pancreatic tissue itself) . It is characterized by sudden upper and middle abdominal pain and elevated blood amylase or lipase in serum tests of patients. Acute pancreatitis is the most common cause of acute abdominal disease hospital admissions (Boxhoorn et al., 2020) . Gallstone and alcohol abuse are the top two risk factors that cause acute pancreatitis. The main clinical symptoms of AP are edema, hemorrhage, and necrosis from mild to severe, which can also result in systemic inflammatory response syndrome (SIRS) and lead to multiple organ dysfunction syndrome (MODS) .
[0004] Intestinal injury is secondary to severe acute pancreatitis and results in aggravation of the systemic inflammatory response, which accounts for the high mortality of AP (He et al., 2017) . Liu et al. (2022) reported that inflammatory response outbreaks, oxidative stress damage, and endocrine disorders are the three main mechanisms of intestinal injury in AP. The development and prognosis of intestinal damage in AP are significantly influenced by the inflammatory response (Ge et al., 2020) . Therefore, alleviation of AP-associated intestinal injury is a key therapeutic approach to severe acute pancreatitis (SAP) . However, few drugs can treat AP-associated intestinal injury, and the efficiency is not satisfactory. Identifying an effective drug to inhibit the intestinal injury of acute pancreatitis is of vital importance.
[0005] Chronic pancreatitis (CP) is a local or diffuse chronic progressive inflammation of the pancreas due to various reasons, accompanied by irreversible damage to the endocrine and exocrine functions of the pancreas. The basic pathological features of CP include chronic inflammatory damage to the pancreatic parenchyma and interstitial fibrosis, pancreatic parenchymal calcification, pancreatic duct dilatation, and pancreatic duct stones. The main clinical manifestations are recurrent upper abdominal pain and pancreatic endocrine and exocrine insufficiency. Based on symptoms, chronic pancreatitis can be divided into two types: chronic recurrent pancreatitis and chronic painless pancreatitis. Chronic pancreatitis (CP) has attracted more and more attention due to its increasing incidence.
[0006] Pancreatitis has always been an important research subject in the medical field, and some new breakthroughs have been made in recent years. Research into early diagnosis of the disease and effective treatments has made remarkable progress. At the same time, researchers continue to pay attention to the pathogenesis of pancreatitis in order to find more effective prevention and control strategies.
[0007] The development of AP is closely related to the accumulation and infiltration of inflammatory cells and factors, according to previous research (Liu et al., 2022) . Inflammasome cascade is an important signal pathway involved in the pathogenesis of acute pancreatitis. NOD-like receptors are intracellular pattern recognition molecules, which are important proteins involved in the inflammatory storm. NOD-like receptor protein 3 (NLRP3) is widely expressed in immune cells (neutrophils, dendritic cells, macrophages) and plays an important role in the formation of NLRP3 inflammasome (Haasken S, et al., 2013; and Strowig T et al., 2012) . NLRP3 inflammasome is an inflammatory complex composed of NLRP3, apoptosis associated speck like protein containing card (ASC) and cysteinyl aspartate specific protein-1 (caspase-1) (Prochnicki T, et al., 2016) . It has been found that inflammasomes lead to the maturation of interleukin-1β (IL-1β) (Girardin SE. et al., 2009) . IL-1β is closely related to SAP, and its upregulation is positively correlated with the severity of the disease. After blocking the expression of IL-1β in SAP, the pathological injury and inflammation of the pancreas have been significantly reduced. However, there is still no clear evidence as to whether blocking the activation pathway of NLRP3 inflammasome could reduce the damage of pancreas and intestinal barrier (Yanghui Shen et. al, 2022) .

Grouping and dosage regimen Model set up The acute pancreatitis will be induced by hourly intraperitoneal injections of caerulein in saline (0.2mpk) for up to 6h in BALB / c mice (20-25 g) . 7 injections in total. (see Figure 1) . Treatment Day 0, Mice will be given the vehicle; G3-G7 groups were arranged to give the drug, the specific administration arrangement is shown in Table 1. On Day 1, G3-G7 groups received compounds at 0 and 6 hours. At 0h and 6h, the test compounds were given first, followed by caerulein, with a difference of about 30s between the first and the last. The dosage and dosing routes are indicated in Table 1. Endpoint On the day of termination (12 h after first Caerulein injection) , all the animals will be sacrificed by CO2, pancreas tissues are collected for HE staining and score, the damage of pancreas are measured by inflammation infiltration, edema and necrosis. Data analysis Data will be shown as Mean ± SEM and analyzed by GraphPad Prism with T-Test, One Way ANOVA or Two Way ANOVA (*P<0.05, **P<0.01, ***P<0.001; VS. G2) .
