Abstract
Ulinastatin is commonly used in the clinic to treat acute pancreatitis (AP), but its therapeutic effect was limited by the presence of the blood-pancreas barrier (BPB) and low specificity. Here, we prepared a macrophage biomimetic nanoparticle (MU) that delivered ulinastatin to address the above issues. Macrophage membrane was used as a shell for a mixture of PEG-PLGA and ulinastatin. It was found that MU showed good stability and biocompatibility in vitro and in vivo. According to in vivo fluorescence imaging, MU displayed a great inflammation targeting effect both in a subcutaneous inflammation model and in situ pancreatitis mouse model, which was ascribed to the presence of adhesion proteins. In vitro and in vivo results demonstrated that MU have a superior AP treatment effect by inhibiting pro-inflammatory factors and keeping cells viability. It was suggested the MU could provide a new strategy for targeted AP treatment.

Abstract
Since the first case reports in Wuhan, China, the SARS-CoV-2 has caused a pandemic and took lives of > 8,35,000 people globally. This single-stranded RNA virus uses Angiotensin-converting enzyme 2 (ACE2) as a receptor for entry into the host cell. Overexpression of ACE2 is mainly observed in hypertensive, diabetic and heart patients that make them prone to SARS-CoV-2 infection. Mitigations strategies were opted globally by the governments to minimize transmission of SARS-CoV-2 via the implementation of social distancing norms, wearing the facemasks, and spreading awareness using digital platforms. The lack of an approved drug treatment regimen, and non-availability of a vaccine, collectively posed a challenge for mankind to fight against the SARS-CoV-2 pandemic. In this scenario, repurposing of existing drugs and old treatment options like convalescent plasma therapy can be one of the potential alternatives to treat the disease. The drug repurposing provides a selection of drugs based on the scientific rationale and with a shorter cycle of clinical trials, while plasma isolated from COVID-19 recovered patients can be a good source of neutralizing antibody to provide passive immunity. In this review, we provide in-depth analysis on these two approaches currently opted all around the world to treat COVID-19 patients. For this, we used "Boolean Operators" such as AND, OR & NOT to search relevant research articles/reviews from the PUBMED for the repurposed drugs and the convalescent plasma in the COVID-19 treatment. The repurposed drugs like Chloroquine and Hydroxychloroquine, Tenofovir, Remdesivir, Ribavirin, Darunavir, Oseltamivir, Arbidol (Umifenovir), Favipiravir, Anakinra, and Baricitinib are already being used in clinical trials to treat the COVID-19 patients. These drugs have been approved for a different indication and belong to a diverse category such as anti-malarial/anti-parasitic, anti-retroviral/anti-viral, anti-cancer, or against rheumatoid arthritis. Although, the vaccine would be an ideal option for providing active immunity against the SARS-CoV-2, but considering the current situation, drug repurposing and convalescent plasma therapy and repurposed drugs are the most viable option against SARS-CoV-2.

Abstract
Current SARS-CoV-2 pandemy mortality created the hypothesis that some populations may be more susceptible to SARS-CoV-2. TMPRSS2 encodes a transmembrane serine protease which plays a crucial role in SARS-CoV-2 cell entry. Single nucleotide polymorphisms (SNPs) in TMPRSS2 might influence SARS-CoV2 entry into the cell. This study aimed to investigate the impact of SNPs on TMPRSS2 function and structure. In silico tools such as Ensembl, Gtex, ExPASY 2, GEPIA, CCLE, KEGG and GO were engaged to characterize TMPRSS2 and its expression profile. The functional effects of SNPs were analyzed by PolyPhen-2, PROVEN, SNAP2, SIFT and HSF. Also, Phyre2, GOR IV and PSIPRED were used to predict the secondary structure of TMPRSS2. Moreover, post-translational modification (PTM) and secretory properties were analyzed through Modpredand Phobius, respectively. Finally, miRNA profiles were investigated by PolymiRTS and miRSNPs. Out of 11,184 retrieved SNPs from dbSNP, 92 showed a different frequency between Asians and other populations. Only 21 SNPs affected the function and structure of TMPRSS2 by influencing the protein folding, PTM, splicing and miRNA function. Particularly, rs12329760 may create a de novo pocket protein. rs875393 can create a donor site, silencer and broken enhancer motifs. rs12627374 affects a wide spectrum of miRNAs profile. This study highlighted the role of TMPRSS2 SNPs and epigenetic mechanisms especially non-coding RNAs in appearance of different susceptibility to SARS-CoV-2 among different populations. Also, this study could pave the way to potential therapeutic implication of TMPRSS2 in designing antiviral drugs. Communicated by Ramaswamy H. Sarma

Impact of continuous regional arterial infusion in the treatment of acute necrotizing pancreatitis: analysis of a national administrative database. J Gastroenterol 2018; 53:1098-1106.

Abstract
BACKGROUND Although continuous regional arterial infusion (CRAI) of protease inhibitors and broad antibiotics has been suggested as one of the therapeutic option for patients with acute necrotic pancreatitis (ANP), the effectiveness has not been well-corroborated in clinical studies. METHODS We conducted a retrospective cohort study using a Japanese national administrative database. Severe acute pancreatitis patients with a poorly enhanced pancreas region (i.e., definitive or clinically suspected ANP) were identified and dichotomized according to whether CRAI was performed. We compared the outcomes of in-hospital mortality, surgical interventions, hospital-free days, and healthcare costs between groups adjusted by the well-validated case-mix adjustment model using a multivariate mixed-effect regression analysis and a propensity score matching analysis. RESULTS Of 243,312 acute pancreatitis patients, 702 eligible patients were identified, of these 339 patients underwent CRAI. The case-mix adjustment model established had good predictability for in-hospital mortality with an area under the receiver operating characteristics curve of 0.87. CRAI was significantly associated with reduced in-hospital mortality [14.5% in the CRAI group vs. 18.2% in the non-CRAI group, adjusted odds ratio (95% confidence interval; CI) = 0.60 (0.36-0.97)]. Significant associations were not observed for the frequency of surgical interventions and mean hospital-free days; however, significantly higher healthcare costs were observed in the CRAI group. Results of the propensity score matching analysis did not alter these results. CONCLUSIONS Analysis of a nationwide large-scale database suggested that CRAI was significantly associated with reduced in-hospital mortality for patients with ANP. Further randomized controlled trials are warranted.

Abstract
OBJECTIVE Administration of heparin or its derivatives has been proved to be beneficial in the treatment of severe acute pancreatitis (SAP). However, drugs administered by conventional intravenous way are difficult to reach the pancreatic tissue and may cause bleeding complications due to coagulation and microcirculatory disturbance following initiation of SAP. In this study, we aimed to assess the effects of low-molecular-weight heparin (LMWH) administered with continuous regional arterial infusion (CRAI) technique in a porcine model of SAP. METHODS Following baseline measurements, 18 animals were divided into three groups: CRAI group (LMWH infused through placed arterial catheter), venous group (LMWH infused through central venous catheter), and SAP control group. We used retrograde intraductal infusion of sodium taurocholate to induce SAP. Global hemodynamic profiles, urine output, systemic oxygenation, and inflammatory and serum biochemical parameters of the animals were studied. At the end of the experiment, histological examination of pancreas, intestine, and lung was performed. RESULTS Continuous regional arterial infusion with LMWH remarkably stabilized hemodynamic profiles, improved systemic oxygenation and peripheral perfusion, alleviated histological injury of pancreas (especially for the necrosis scale), and downregulated inflammatory response when compared with the other two groups. Moreover, serum D-dimer level also decreased most significantly in the CRAI group (474 ± 144 vs. 664 ± 155 µg/L in the venous group and 945 ± 351 µg/L in the controls at the end), partly indicating ameliorated coagulation disorders in the study group. No bleeding complication was observed in the CRAI group, whereas two animals in the venous group presented gastrointestinal hemorrhage. CONCLUSIONS Continuous regional arterial infusion with LMWH exhibits strong therapeutic effects in the course of SAP with great safety. Human studies using this novel therapy are required to assess these potential benefits in the clinical setting.

Abstract
BACKGROUND Continuous regional arterial infusion (CRAI) is a drug delivery system, which dramatically increases the drug concentration in the pancreas. Previous clinical and basic studies have demonstrated the possible therapeutic efficacy of CRAI for severe acute pancreatitis (SAP). This meta-analysis of all published randomized controlled trials (RCTs) was conducted to assess the efficacy and safety of CRAI for the treatment of SAP. DATA SOURCES Up to August 10, 2014, RCTs comparing CRAI with intravenous infusion for SAP in PubMed, Embase, EBSCO, MEDLINE, Science Citation Index Expanded, Cochrane Library, China Academic Journals Full-Text Database, Chinese Biomedical Literature Database, and Chinese Scientific Journals Database were selected by two independent reviewers. The relative risk (RR) and their 95% confidence intervals (CI) for duration of elevated serum amylase and urine amylase, duration of abdominal pain, infection rate, incidence of complication, overall mortality, curative rate, hospital stay and details of subgroup analysis were extracted. Meta-analyses were made using the software Review Manager (RevMan version 5.10). RESULTS Six RCTs with 390 patients meeting the inclusion criteria were included in the final analysis. Compared with intravenous infusion route, CRAI significantly shortened the duration of elevated urine amylase (MD=-2.40, 95% CI=-3.20, -1.60; P<0.00001) and the duration of abdominal pain (MD=-1.46, 95% CI=-1.94, -0.98; P<0.00001), decreased the incidence of complication (RR=0.35, 95% CI=0.15, 0.81; P=0.01) and overall mortality (RR=0.25, 95% CI=0.08, 0.78; P=0.02), shortened the duration of hospital stay (MD=-10.36, 95% CI=-17.05, -3.68; P=0.002), and increased the curative rate (RR=1.66, 95% CI=1.13, 2.46; P=0.01). No mortality and catheter-related infections due to CRAI administration was reported in these studies. Subgroup analysis showed that the combination of drug administration via CRAI did not significantly improve the outcomes. CONCLUSION CRAI is effective for the treatment of SAP, and the combination of drug administration via CRAI did not have a significant effect on the improvement of the outcomes.

Abstract
Objective Investigate the therapeutic effect of regional arterial infusion (RAI) with Aspirin-Triggered Lipoxin A4 (ATL) in experimental severe acute pancreatitis (SAP) in rats. Materials and Methods SAP was induced by injection of 5% sodium taurocholate into the pancreatic duct. Rats with SAP were treated with ATL (the ATL group) or physiological saline (the SAP group) infused via the left gastric artery 30 min after injection of sodium taurocholate. The sham group was subjected to the same surgical procedure, though without induction of SAP. Serum levels of amylase, phospholipase A2 (PLA2), interleukin-1β (IL-1β), IL-6 and tumor necrosis factor-α (TNF-α) were measured at 12 and 24 h after induction of SAP. Ascitic fluid, the pancreatic index (wet weight ratio) and myeloperoxidase (MPO) levels in the pancreas were determined and histopathological findings were evaluated. The expression of intercellular adhesion molecule-1 (ICAM-1), platelet endothelial cell adhesion molecule-1 (PECAM-1), NF-κB p65, and heme oxygenase-1 (HO-1) in the pancreas were estimated by immunofluorescence and western blot, respectively. Results ATL rats had lower serum levels of TNF-α, IL-1β, and IL-6 (P<0.01), PLA2 (P<0.05), and amylase levels (P<0.05) studied as compared with the SAP group. The pancreatic index in the ATL group decreased only at 24 h as compared with the SAP group (P<0.05). The histopathological findings and MPO levels in the pancreas significantly decreased in the ATL group as compared to the SAP group (P<0.05 and P<0.01, respectively). Immunofluorescence and western blot showed that ATL attenuated the expression of NF-κB p65, ICAM-1 and PECAM-1 in the pancreas, and increased the expression of HO-1 in SAP animals. Conclusions We demonstrated that RAI with ATL attenuated the severity of experimental SAP, maybe achieved by improving the expression of HO-1, and down-regulating the NF-κB signaling pathway, with decreased expression of ICAM-1 and PECAM-1 and reduced generation of pro-inflammatory cytokines.

Abstract
Introduction Although continuous regional arterial infusion (CRAI) of a protease inhibitor and an antibiotic may be effective in patients with severe acute pancreatitis, CRAI has not yet been validated in large patient populations. We therefore evaluated the effectiveness of CRAI based on data from a national administrative database covering 1,032 Japanese hospitals. Methods In-hospital mortality, length of stay and costs were compared in the CRAI and non-CRAI groups, using propensity score analysis to adjust for treatment selection bias. Results A total of 17,415 eligible patients with acute pancreatitis were identified between 1 July and 30 September 2011, including 287 (1.6%) patients who underwent CRAI. One-to-one propensity-score matching generated 207 pairs with well-balanced baseline characteristics. In-hospital mortality rates were similar in the CRAI and non-CRAI groups (7.7% vs. 8.7%; odds ratio, 0.88; 95% confidence interval, 0.44–1.78, P = 0.720). CRAI was associated with significantly longer median hospital stay (29 vs. 18 days, P < 0.001), significantly higher median total cost (21,800 vs. 12,600 United States dollars, P < 0.001), and a higher rate of interventions for infectious complications, such as endoscopic/surgical necrosectomy or percutaneous drainage (2.9% vs. 0.5%, P = 0.061). Conclusions CRAI was not effective in reducing in-hospital mortality rate in patients with acute pancreatitis, but was associated with longer hospital stay and higher costs. Randomized controlled trials in large numbers of patients are required to further evaluate CRAI for this indication.

Abstract
OBJECTIVES A randomized controlled trial was conducted to clarify whether continuous regional arterial infusion (CRAI) of protease inhibitor and antibiotic could reduce mortality rate of severe acute pancreatitis (SAP). METHODS Seventy-eight patients with SAP were included in the study. Thirty-nine patients were treated with CRAI, 31 patients completed the study; and another group of 39 patients was treated without CRAI therapy. Groups were well matched in clinical characteristics. The CRAI patients were treated continuously with nafamostat mesylate 240 mg/d and imipenem 1 g/d for 5 days via one of the arteries perfusing the pancreas. Later, imipenem was given intravenously (0.5 g every 8 hours) for 9 days. The non-CRAI patients received imipenem (0.5 g every 8 hours) intravenously for 14 days. Statistical analysis of the intention-to-treat (ITT) group was performed. RESULTS Lack of septic complications was observed in 23 patients with CRAI therapy and 20 non-CRAI patients (not significant). The additional antibiotics were applied in 8 of CRAI patients and in 18 non-CRAI (ITT, P = 0.02). Mortality rate was 5.1% in CRAI and 23.1% in non-CRAI group (ITT, P = 0.02). Urgent surgical intervention was necessary in 10.3% CRAI patients and in 33.3% non-CRAI (ITT, P = 0.01). CONCLUSIONS The results show that CRAI of protease inhibitor and antibiotic is effective in preventing complications and in reducing mortality rate in SAP.

Abstract
OBJECTIVES Protease inhibitors showed protective effects on animal models of acute pancreatitis when administered before induction of pancreatitis, and results when administered after induction are uncertain. We assessed the effects of nafamostat mesilate in a mouse model of cerulein-induced pancreatitis comparing results of before and after induction. METHODS Cerulein was injected to mice intraperitoneally to induce pancreatitis, and they received intravenous nafamostat mesilate before and after induction. Serum concentrations of amylase and lipase, histological changes, and tissue expression of myeloperoxidase were measured. In addition, tissue activation of p38 mitogen-activated protein kinase (MAPK) and interleukin-6 was evaluated. RESULTS Development of pancreatitis was prevented by pretreatment with nafamostat mesilate. However, such effect was not shown when given after induction, although it partially suppressed myeloperoxidase expression and infiltration of inflammatory cells. Tissue expression of phospho-p38 MAPK was prominent in mice with pancreatitis and suppressed by pretreatment with nafamostat mesilate. Interleukin-6 expression was not influenced by either cerulein or nafamostat mesilate. CONCLUSIONS The development of pancreatitis was prevented by treating mice with nafamostat mesilate before induction, however, this finding was not observed if administered after injection of cerulein. Pretreatment with nafamostat mesilate suppressed activation of p38 MAPK.

Abstract
Acute pancreatitis (AP) is characterized by edema, acinar cell necrosis, hemorrhage, and severe inflammation of the pancreas. Patients with AP present with elevated blood and urine levels of pancreatic digestive enzymes, such as amylase and lipase. Severe AP may lead to systemic inflammatory response syndrome and multiorgan dysfunction syndrome, which account for the high mortality rate of AP. Although most (>80%) cases of AP are associated with gallstones and alcoholism, some are idiopathic. Although the pathogenesis of AP has not yet been elucidated, a common feature is the premature activation of trypsinogen within pancreatic tissues, which triggers autodigestion of the gland. Recent advances in basic research suggest that etiologic factors including cyclooxygenase-2, substance P, and angiotensin II may have novel roles in this disease. Basic research data obtained thus far have been based on animal models of AP ranging from mild edematous pancreatitis to severe necrotizing pancreatitis. In view of this, an adequate selection of experimental animal models is of paramount importance. Notwithstanding these animal models, it should be emphasized that none of these models mimic the clinical situation where varying degrees of severity usually occur. In this review, commonly used animal models of AP will be critically evaluated. A discussion of recent advances in our knowledge about AP risk factors is also included.

Abstract
OBJECTIVES The rat experimental model of continuous regional arterial infusion of protease inhibitor (CRAI) on acute pancreatitis has yet to be established. Therefore, the aims of this study were (1) to establish the rat experimental model of CRAI and (2) to evaluate the effects of nafamostat on rat severe acute pancreatitis via different routes of administration. METHODS The rat internal jugular vein or the celiac artery was infused with nafamostat, and the concentration of nafamostat in the lung and pancreas was measured. After the induction of severe acute pancreatitis, rats received intravenous or regional intraarterial infusion of nafamostat and then concentrations of trypsinogen activated peptide (TAP) and serum interleukin (IL-6), and histologic sections of the pancreas were examined and the 96-hour survival rate was evaluated. RESULTS CRAI rats had higher concentrations of nafamostat in the pancreas than those infused intravenously. However, CRAI rats had lower concentrations of nafamostat in the lung that those infused intravenously. CRAI significantly reduced the levels of TAP and pancreatic necrosis. Moreover, the levels of serum IL-6 and the mortality rate were significantly reduced after CRAI compared with the intravenous infusion of nafamostat. CONCLUSION The effectiveness of the rat experimental model of CRAI on acute pancreatitis was clearly demonstrated. The concentration of nafamostat in the lung and pancreas and the effects of nafamostat differ according to the route of administration.

Abstract
AIM: To evaluate the impact of time interval for hemofiltration (HF) on the prognosis of severe acute pancreatitis (SAP).
METHODS: Thirty-six consecutive patients with severe acute pancreatitis were included in the study. Atlanta classification system was applied for stratification. They were randomly divided into short veno-venous HF group, (SVVH, Group 1, 20 patients); and long veno-venous HF group (LVVH, Group 2, 16 patients). In group 1, SVVH was stopped when the abdominal signs disappeared, and heart rate and breath rate were less than 90 beats/min and 20 times/min, respectively. HF was stopped if SVVH was continued, and when heart rate and breath rate were more than 90 beats/min and 20 times/min again (Group 2). Except that the time interval for HF was different, other parameters for HF were the same. And conservative curing rate, survival rate, cost for hospital stay and length of hospital stay were observed.
RESULTS: Time interval for HF in Group 1 (3.81 ± 1.3 h) was shorter than that of in Group 2 (9.38 ± 2.9 hr), P < 0.01. Conservative curing rate (90%) in Group 1 was much higher than that in Group 2 (56.3%) (P < 0.05); but cost in Group 1 (RMB 56600 ± 56400 Yuan) was lower than that in Group 2 (RMB 137000 ± 105000 Yuan) (P < 0.05). And the survival rate (95%) in Group 1 was higher than that in Group 2 (81.3%) (P < 0.25); however, hospital stay in Group 1 (44.3 ± 41 d) was shorter than that in Group 2 (55.2 ± 39.5 d) (P < 0.2). So, the prognosis was not improved through the prolongation of time interval for HF, but side-effects were seen.
CONCLUSION: The prognosis was not further improved by LVVH in the treatment of SAP, with side-effects. Time interval for HF plays an important role in treatment of SAP in early stage. SVVH is thought to be superior to LVVH; and LVVH is superior to CVVH in early (72 h) treatment of SAP.
