Lan WP, Guo W, Zhou X, Li Z. Research trends on traditional Chinese medicine and acute pancreatitis: A bibliometric analysis from 2007 to mid-2023. Heliyon 2024; 10:e25659. [PMID: 38455538 PMCID: PMC10918020 DOI: 10.1016/j.heliyon.2024.e25659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 01/23/2024] [Accepted: 01/31/2024] [Indexed: 03/09/2024] Open
Abstract
Traditional Chinese Medicine (TCM) is a unique medical system of historic significance, holding substantial influence within China and beyond. In recent years, the efficacy of TCM in treating acute pancreatitis has been substantiated. Despite over two decades of development in this domain, a bibliometric analysis illustrating TCM's role in acute pancreatitis remains scarce. OBJECTIVE This study aims to conduct a comprehensive analysis of findings in the field of acute pancreatitis and TCM using machine learning and text-analyzing methodologies. The intent is to provide scientific and intuitive support to researchers and clinicians. METHODS We searched the Web of Science Core Collection database for publications and related literature from 2007 to mid-2023. Tools such as Excel, Citespace V, and Vosviewer were utilized for bibliometric analysis. That included assessing published and cited counts, co-authorship mapping, co-citation analysis, burst detection, and keyword analysis. RESULTS The study revealed a fluctuating growth trend in the number of publications and citations since 2007. As many as 147 institutions from 13 countries, with a total of 756 authors, have published 202 papers in 76 academic journals. Sichuan University in China and Tang Wenfu have been recognized as the most influential national institution and author. The most frequently published journal is "Pancreas", while the most cited is the "World Journal of Gastroenterology". Commonly used single herbs in this field include Baicalin, Emodin, Rhubarb, and Salvia miltiorrhizae. Frequently used herbal formulations include Da chengqi decoction, Chaiqin chengqi decoction, and Qing yi decoction. Current research hotspots primarily surround concepts like hmgb1, nf-kappab, nfr2, oxidative stress, exosomes, nlrp3, pyroptosis, etc. Potential future research themes could relate to pharmacology, reducing hmgb1, inflammatory response, cell activation, Qing Yi-decoction, etc. This review holds significant guiding importance for clinical and scientific research into TCM treatment for acute pancreatitis in the future.

Baicalin suppresses renal fibrosis through microRNA-124/TLR4/NF-κB axis in streptozotocin-induced diabetic nephropathy mice and high glucose-treated human proximal tubule epithelial cells. J Physiol Biochem 2020; 76:407-416. [PMID: 32500512 DOI: 10.1007/s13105-020-00747-z] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Accepted: 05/20/2020] [Indexed: 01/02/2023]
Abstract
Renal fibrosis is a major pathological event in the development of diabetic nephropathy (DN). Baicalin is a flavonoid glycoside that possesses multiple pharmacological properties including anti-fibrotic activity. In the present study, the effects of baicalin on renal fibrosis along with related molecular basis were investigated in streptozotocin (STZ)-induced DN mouse model and high glucose (HG)-treated HK-2 human proximal tubule epithelial cell model. Renal injury was evaluated through blood urea nitrogen (BUN) and serum creatinine (Scr) levels and urine albumin creatine ratio (ACR). Renal fibrosis was assessed by type IV collagen (COLIV) and fibronectin (FN) protein expression and histopathologic analysis via Masson trichrome staining. Protein levels of COLIV, FN, NF-κB inhibitor alpha (IκBα), phosphorylated IκBα (p-IκBα), p65, phosphorylated p65 (p-p65), and toll-like receptor 4 (TLR4) were measured by western blot assay. MicroRNA-124 (miR-124) and TLR4 mRNA levels were detected by RT-qPCR assay. The interaction of miR-124 and TLR4 was examined by bioinformatics analysis, luciferase reporter assay, and RIP assay. Baicalin or miR-124 attenuated renal injury and fibrosis in STZ-induced DN mice. Baicalin inhibited the increase of COLIV and FN expression induced by HG through upregulating miR-124 in HK-2 cells. TLR4 was a target of miR-124. MiR-124 inhibited TLR4/NF-κB pathway activation and the inactivation of the NF-κB pathway hindered COLIV and FN expression in HG-stimulated HK-2 cells. Baicalin prevented renal fibrosis by increasing miR-124 and inactivating downstream TLR4/NF-κB pathway in DN, hinting the pivotal values of baicalin and miR-124 in the management of DN and renal fibrosis.

Phytoceuticals in Acute Pancreatitis: Targeting the Balance between Apoptosis and Necrosis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:5264592. [PMID: 29686719 PMCID: PMC5857302 DOI: 10.1155/2018/5264592] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2017] [Revised: 11/29/2017] [Accepted: 12/20/2017] [Indexed: 12/11/2022]
Abstract
Despite recent advances in understanding the complex pathogenesis of pancreatitis, the management of the disease remains suboptimal. The use of phytoceuticals (plant-derived pleiotropic multitarget molecules) represents a new research trend in pancreatology. The purpose of this review is to discuss the phytoceuticals with pancreatoprotective potential in acute pancreatitis and whose efficacy is based, at least in part, on their capacity to modulate the acinar cell death. The phytochemicals selected, belonging to such diverse classes as polyphenols, flavonoids, lignans, anthraquinones, sesquiterpene lactones, nitriles, and alkaloids, target the balance between apoptosis and necrosis. Activation of apoptosis via various mechanisms (e.g., inhibition of X-linked inhibitor of apoptosis proteins by embelin, upregulation of FasL gene expression by resveratrol) and/or inhibition of necrosis seem to represent the essential key for decreasing the severity of the disease. Apart from targeting the apoptosis/necrosis balance, the phytochemicals displayed other specific protective activities: inhibition of inflammasome (e.g., rutin), suppression of neutrophil infiltration (e.g., ligustrazine, resveratrol), and antioxidant activity. Even though many of the selected phytoceuticals represent a promising therapeutic alternative, there is a shortage of human evidence, and further studies are required to provide solid basis to justify their use in the treatment of pancreatitis.

Int J Mol Med 2018; 41:1992-2002. [PMID: 29393361 PMCID: PMC5810201 DOI: 10.3892/ijmm.2018.3427] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2017] [Accepted: 12/22/2017] [Indexed: 12/15/2022] Open
Abstract
Hepatic fibrosis is a physiological response to liver injury that includes a range of cell types. The pathogenesis of hepatic fibrosis currently focuses on hepatic stellate cell (HSC) activation into muscle fiber cells and fibroblasts. Baicalin is a flavone glycoside. It is the glucuronide of baicalein, which is extracted from the dried roots of Scutellaria baicalensis Georgi. Previous work focused on the anti-viral, -inflammatory and -tumor properties of baicalin. However, the potential anti-fibrotic effects and mechanisms of baicalin are not known. The present study demonstrated that baicalin influenced the activation, proliferation, apoptosis, invasion and migration of platelet-derived growth factor-BB-induced activated HSC-T6 cells in a dose-dependent manner. To investigate the anti-fibrotic effect of baicalin, a one-color micro (mi)RNA array and reverse transcription-quantitative polymerase chain reaction analyses were used. Results demonstrated that baicalin increased the expression of the miRNA, miR-3595. In addition, the inhibition of miR-3595 substantially reversed the anti-fibrotic effect of baicalin. The present data also suggested that miR-3595 negatively regulates the long-chain-fatty-acid-CoA ligase 4 (ACSL4). Furthermore, ACSL4 acted in a baicalin-dependent manner to exhibit anti-fibrotic effects. Taken together, it was concluded that baicalin induces miR-3595 expression that modulates the expression levels of ACSL4. To the best of our knowledge, the present study is the first to demonstrate that baicalin induces overexpression of human miR-3595, and subsequently decreases the expression of ACSL4, resulting in an anti-fibrotic effect.

Abstract
Background: Myoglobinuric acute kidney injury is a uremic syndrome that develops due to damage of skeletal muscle. Free radicals and nitric oxide play an important role in the pathogenesis of myoglobinuric acute kidney injury. Baicalin has multiple bioactivities, including antimicrobial, anti-inflammatory and antioxidant properties and is a potent free radical scavenger. Aims: To investigate the nephroprotective mechanism of baicalin on myoglobinuric acute kidney injury. Study Design: Animal experimentation. Methods: In our study, male Sprague Dawley rats were divided into 4 groups. Control (n=8), Baicalin (n=8), myoglobinuric acute kidney injury (n=10) and myoglobinuric acute kidney injury + baicalin (n=10). The rats were deprived of water for 24 hours before receiving intramuscular injection. The control and baicalin groups were injected intramuscularly with saline (8 ml/kg), and the myoglobinuric acute kidney injury and myoglobinuric acute kidney injury + baicalin groups were given 50% glycerol 8 ml/kg. One hour later, the control and myoglobinuric acute kidney injury groups received saline intraperitoneally, and the baicalin and myoglobinuric acute kidney injury + baicalin groups were given 200 mg/kg baicalin. Twenty-four hours after the glycerol injection, urine and blood samples were taken, and the kidneys of the rats were harvested under intraperitoneally injections of anaesthesia. Results: We found that the levels of creatinine, urea, nitric oxide, alanine transaminase, aspartate aminotransferase, creatine kinase in serum samples, malondialdehyde, nitric oxide, inducible nitric oxide synthase, and endothelial nitric oxide synthase concentrations in renal tissue were increased in the myoglobinuric acute kidney injury group compared with the control group (p<0.05). The nitric oxide and glutathione levels in the kidney were significantly decreased in the myoglobinuric acute kidney injury + baicalin group compared with the myoglobinuric acute kidney injury group (p<0.05). There were no significant differences between any other parameters. Conclusion: Our results did not show any protective effect of baicalin on myoglobinuric acute kidney injury, possibly because the different effective factors in the pathogenesis of experimental myoglobinuric acute kidney injury used in this experiment deviate from other experimental models. Moreover, detailed studies are needed to clarify the effects of baicalin in different doses and treatment durations in glycerol-induced acute kidney injury model.

Abstract
Background: Severe acute pancreatitis (SAP) and obstructive jaundice (OJ) are frequent recurring diseases that bring about huge threat to human health. Some reports have demonstrated that Salviae miltiorrhizae can protect multiple organs of SAP and OJ model animals or patients, but their related mechanisms were not clear. In this study, we observed the effects of Salvia miltiorrhizae injection on apoptosis and NF-κB expression in kidney and explored the protective effect and mechanism of Salvia miltiorrhizae on the kidney of SAP or OJ rats. The results obtained will provide a theoretical basis for clinical application of Salvia miltiorrhizae. Material and Methods: A total of 288 rats were used for SAP -and OJ-associated experiments. The mortality rates of rats, the contents of serum BUN and CREA, the expression levels of Bax, NF-κB proteins and the apoptosis index were observed, respectively. Results: The pathological changes in the kidney of SAP or OJ rats in treated group were mitigated to varying degrees. At 6 and 12 hours after operation in SAP rats or on 21 and 28 days after operation in OJ rats, the contents of serum CREA in treated group were significantly lower than those in model control group; At 3 and 6 hours after operation, the staining intensity of Bax protein of kidney in treated group was significantly lower than that in model control group; on 14 days after operation, the apoptosis index in the kidney of OJ rats in treated group was significantly lower than that in model control group. Conclusion: Salvia miltiorrhizae can exert protective effects on the kidney of SAP and OJ rats.

Abstract
Acute pancreatitis (AP) is a commonly occurring gastrointestinal disorder. An increase in the annual incidence of AP has been observed, and it causes acute hospitalization and high mortality. The diagnosis and treatment guidelines for AP recommend conservative medical treatments focused on reducing pancreatic secretion and secondary injury, as a primary therapeutic approach. Unfortunately, the existing treatment options have limited impact on the incidence and severity of AP due to the complex and multifaceted pathological process of this disease. In recent decades, Chinese herbal medicines (CHMs) have been used as efficient therapeutic agents to attenuate AP in Asian countries. Despite early cell culture, animal models, and clinical trials, CHMs are capable of interacting with numerous molecular targets participating in the pathogenesis of AP; however, comprehensive, up-to-date communication in this field is not yet available. This review focuses on the pharmacological activities of CHMs against AP in vitro and in vivo and the underlying mechanisms. A computational prediction of few selected and promising plant-derived molecules (emodin, baicalin, resveratrol, curcumin, ligustrazine, and honokiol) to target numerous proteins or networks involved in AP was initially established based on a network pharmacology simulation. Moreover, we also summarized some potential toxic natural products for pancreas in order to more safe and reasonable medication. These breakthrough findings may have important implications for innovative drug research and the future development of treatments for AP.

Abstract
Lead (Pb) exposure is a global environmental problem that can deplete body antioxidant enzymes, causing damage to various macromolecules and ultimately cell death. Pb exposure could lead to serious renal damage. Baicalin, a traditional Chinese medicine, could protect against renal injury through inhibition of oxidative stress and apoptosis. This study was designed to investigate the protective efficacy of baicalin against Pb-induced nephrotoxicity in mice and to elucidate the potential mechanisms using animal experiment. The results revealed that baicalin decreased Pb-induced bodyweight loss, declined kidney coefficients, and ameliorated renal function and structure in a dose-dependent manner. Meanwhile, baicalin dose dependently increased Pb-induced activity of SOD and GSH-Px, while the content of MDA in the kidney was decreased. In addition, baicalin enhanced the Bcl-2/Bax ratio associated with apoptosis in the kidney. These data indicated that further investigation of the use of baicalin as a new natural chemopreventive agent against Pd poisoning is warranted.

Abstract
Aim. Acute pancreatitis is an inflammatory intra-abdominal disease, which takes a severe form in 15–20% of patients and can result in high mortality especially when complicated by acute renal failure. The aim of this study is to assess the possible reduction in the extent of acute kidney injury after administration of eugenol in an experimental model of acute pancreatitis. Materials and Methods. 106 male Wistar rats weighing 220–350 g were divided into 3 groups: (1) Sham, with sham surgery; (2) Control, with induction of acute pancreatitis, through ligation of the biliopancreatic duct; and (3) Eugenol, with induction of acute pancreatitis and eugenol administration at a dose of 15 mg/kg. Serum urea and creatinine, histopathological changes, TNF-α, IL-6, and MPO activity in the kidneys were evaluated at predetermined time intervals. Results. The group that was administered eugenol showed milder histopathological changes than the Control group, TNF-α activity was milder in the Eugenol group, and there was no difference in activity for MPO and IL-6. Serum urea and creatinine levels were lower in the Eugenol group than in the Control group. Conclusions. Eugenol administration was protective for the kidneys in an experimental model of acute pancreatitis in rats.

JOURNAL OF ETHNOPHARMACOLOGY 2015; 161:255-78. [PMID: 25543018 DOI: 10.1016/j.jep.2014.12.027] [Citation(s) in RCA: 57] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2014] [Revised: 12/18/2014] [Accepted: 12/19/2014] [Indexed: 05/21/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Oroxylum indicum\ (L.) Kurz has been used for centuries as a traditional medicine in Asia in ethnomedicinal systems for the prevention and treatment of several diseases, such as jaundice, arthritic and rheumatic problems, gastric ulcers, tumors, respiratory diseases, diabetes, and diarrhea and dysentery, among others. The present review provides scientific evidence supporting the therapeutic potency of the plant for ethnomedicinal uses and identifies gaps for future research to facilitate commercial exploitation. METHODS This review is based on available information on traditional uses and phytochemical, pharmacological, clinical and toxicity data for Oroxylum indicum that was collected from electronic (SciFinder, PubMed, Science Direct, and ACS, among others) and library searches. KEY FINDING A variety of traditional medicinal uses of Oroxylum indicum in different Southeast and South Asian countries have been reported in books describing the uses of these plants. Phytochemical investigations of the different parts of the plant resulted in identification of approximately 111 compounds, among which flavonoids, naphthalenoids and cyclohexylethanoids are the predominant groups. The crude extracts and their isolates exhibit a wide spectrum of in vitro and in vivo pharmacological activities involving antimicrobial, anti-inflammatory, anti-arthritic, anticancer, anti-ulcer, hepatoprotective, antidiabetic, antidiarrheal and antioxidant activities. Flavonoids are the major constituents of all parts of the plant. From a toxicity perspective, only aqueous and ethanolic extracts of stem bark, root bark and fruits have been assessed and found to be safe. The major flavonoids of the stem bark, such as baicalein, chrysin and oroxylin A, were reported for the first time as natural flavonoids with potent inhibitory activity against endoprotease enzymes and proprotein convertases, which play a key role in the growth of cancer and in viral and bacterial infections. Flavonoids are the active components of bioactive extracts. Several Ayurvedic medicines have been formulated either singly using this plant or along with other herbs for the treatment of different diseases. CONCLUSIONS Pharmacological results have supported some traditional medicinal uses of Oroxylum indicum. Several extracts and their isolates have been reported to exhibit interesting pharmacological properties. These components could be useful as sources of modern medicines following future detailed studies to elucidate their underlying mechanisms, toxicity, synergistic effects and clinical trials. Attention should also be focused on pharmacological studies investigating the traditional uses of the plant, which have not been yet addressed, as well as clinical studies investigating commercial Ayurvedic medicines and other ethnomedicinal preparations in human subjects based on this plant to confirm the safety and quality of the preparations.

Exp Ther Med 2015; 9:1171-1177. [PMID: 25780405 PMCID: PMC4353754 DOI: 10.3892/etm.2015.2251] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2014] [Accepted: 01/20/2015] [Indexed: 01/15/2023] Open
Abstract
The aim of this study was to investigate the effect of early peritoneal lavage with ulinastatin on the outcome of a rat model of severe acute pancreatitis (SAP). A total of 80 male Wistar rats were randomly divided into the following groups: Sham-operated (C), SAP model (M), saline lavage (SL), intravenous ulinastatin (IU), early ulinastatin lavage (EUL) and late ulinastatin lavage (LUL). Intraperitoneal lavage or injection were performed immediately subsequent to the establishment of the SAP model in groups SL, IU and EUL and 3 h later in group LUL. Intraperitoneal lavage with or without ulinastatin was performed for 3 h. The survival time of the rats in groups C, M, EUL and LUL was recorded over a 12-h period and the median survival time was calculated. At 3 h after the induction of SAP, histopathological analyses were performed and the biochemical parameters of groups C, M, SL, IU and EUL were assessed. Groups EUL and LUL exhibited an increased median survival time compared with Group M, with the survival time of the rats in group EUL markedly longer than that in the group LUL rats. Group SL, IU and EUL rats were found to have reduced plasma activities of amylase, lipase, aspartate transaminase and alanine transaminase, with the biggest change observed in the group EUL rats. Furthermore, the intervention in groups SL and EUL was more effective at reducing creatinine and urea levels than that in group IU. Rats in group EUL exhibited a greater inhibition of the SAP-induced increase in troponin T levels than rats in groups SL and IU. The pathological severity scores of the pancreas, liver, kidney and lung in group EUL were significantly lower than those in groups M and better than those in groups SL and IU. In conclusion, early intraperitoneal lavage with ulinastatin significantly improves the median survival time and protects multi-organ function in an SAP model.

Correlation between serum levels of high mobility group box-1 protein and pancreatitis: a meta-analysis. BIOMED RESEARCH INTERNATIONAL 2015; 2015:430185. [PMID: 25695079 PMCID: PMC4324490 DOI: 10.1155/2015/430185] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/17/2014] [Accepted: 10/30/2014] [Indexed: 12/12/2022]
Abstract
Background. Aberrant expression of high mobility group box-1 protein (HMGB1) contributes to the progression of various inflammatory diseases. This meta-analysis focused on the clinical significance of serum HMGB1 levels in pancreatitis patients, with the goal of building a novel diagnostic score model. Method. We conducted a meta-analysis by searching in the PubMed, Embase, Web of Science, Cochrane Library, CISCOM, CINAHL, Google Scholar, China BioMedicine (CBM), and China National Knowledge Infrastructure (CNKI) databases without any language restrictions. Studies were pooled and standard mean difference (SMD) and its corresponding 95% confidence intervals (95% CIs) were calculated. Version 12.0 STATA software was used for statistical analysis. Results. We performed a final analysis of 841 subjects from 12 clinical case-control studies. The meta-analysis results showed a positive association between serum HMGB1 levels and the progression of pancreatitis. In the subgroup analysis by country, high serum level of HMGB1 may be related to pancreatitis progression in China, Korea, Hungary, and Japan populations (all P < 0.05). Conclusion. The present meta-analysis indicated that serum HMGB1 level was statistically elevated in patients with pancreatitis, and thus serum levels of HMGB1 could be determined to be a useful biomarker for pancreatitis patients.

Abstract
OBJECTIVE To investigate the effect of Chaiqin Chengqi Decoction (,CQCQD) on cholecystokinin receptor 1 (CCKR1)-mediated signal transduction of pancreatic acinar cell in rats with acute necrotic pancreatitis (ANP). METHODS Twenty-seven Sprague-Dawley rats were randomized into three groups: the control group, the ANP group, and the CQCQD group (9 in each group). ANP rats were induced by two intraperitoneal injections of 8% L-arginine (pH=7.0, 4.4 g/kg) over a 2-h period. Rats were treated with 1.5 mL/100 g body weight of CQCQD (CQCQD group) or physiological saline (control and ANP groups) at 2 h interval. And 6 h after induction, pancreatic tissues were collected for histopathological examination. Pancreatic acinar cells were isolated for determination of CCKR1 mRNA and protein expression, phospholipase C (PLC) and inositol-1,4,5-triphosphate (IP3), and determination of fluorescence intensity (FI) as a measure of intracellular calcium ion concentration [Ca(2+)]i. RESULTS The pancreatic histopathological score (6.2 ± 1.1) and the levels of PLC (1,187.2 ± 228.2 μg/mL) and IP3 (872.2 ± 88.4 μg/mL) of acinar cells in the ANP group were higher than those in the control (2.8 ± 0.4, 682.5 ± 121.8 μg/mL, 518.4 ± 115.8 μg/mL) and the CQCQD (3.8 ± 0.8, 905.3 ± 78.5 μg/mL, 611.0 ± 42.5 μg/mL) groups (P<0.05). [Ca(2+)]i FI for the ANP group (34.8±27.0) was higher than that in the control (5.1 ± 2.2) and CQCQD (12.6 ± 2.5) groups (P<0.05). The expression of pancreatic acinar cell CCKR1 mRNA in the ANP group was up-regulated (expression ratio=1.761; P=0.024) compared with the control group. The expression of pancreatic acinar cell CCKR1 mRNA in the CQCQD group was down-regulated (expression ratio=0.311; P=0.035) compared with the ANP group. The ratio of gray values of the CCKR1 and β-actin in the ANP group (1.43 ± 0.17) was higher than those in the control (0.70 ± 0.15) and CQCQD (0.79 ± 0.11) groups (P<0.05). CONCLUSIONS Pancreatic acinar cell calcium overload of ANP induced by L-arginine was related to the up-regulated expressions of pancreatic acinar cell CCKR1 mRNA and protein. CQCQD can down-regulate expressions of pancreatic acinar cell CCKR1 mRNA and protein to reduce the PLC and IP3 of pancreatic acinar cells, relieving the calcium overload and reducing the pathological changes in rats with ANP.

Abstract
The aim of this study was to observe scutellarin parenteral solution's therapeutic effects and mechanisms in rats with severe acute pancreatitis (SAP). We divided SD rats into four groups randomly: (1) sham-operated group, (2) model control group, (3) scutellarin-treated group, and (4) Salvia miltiorrhiza-treated group. All of those rats in the abovementioned groups are randomly subdivided into 6 and 12 h subgroups, respectively, according to the postoperative time. Rats have been mercifully killed at different time after operation, and then detected their serum amylase, contents of ALT, AST, BUN, and Cr and observed the pathologic changes of multiple organs (pancreas, liver, kidneys, and lungs). We found that the survival rates have no marked differences (P < 0.05) between model control group and two treated groups at any time points. AST and BUN serum contents have no marked difference (P > 0.05). ALT serum contents in S. miltiorrhiza-treated group (6 and 12 h) and scutellarin-treated group (12 h) are obviously less than those in model control group (P < 0.05). The serum contents of Cr and amylase in scutellarin-treated group (6 h) are obviously less than those in model control group (P < 0.05). There is a different degree of relief on the pathologic changes of multiple organs in the two treated groups compared with those in model control group, of which pancreas and liver's pathologic severity scores in scutellarin-treated group (6 and 12 h) have reduced (P < 0.01) significantly compared with those in the model control group. However, there are no significant differences between scutellarin-treated group and S. miltiorrhiza-treated group (P > 0.05). We think the scutellarin parenteral solution has a certain protective effect on SAP rats' multiple organ injuries.

Abstract
BACKGROUND Inflammatory and oxidative damage play a pivotal role in cerebral ischemic pathogenesis and may represent a therapeutic target. Octreotide (OCT) has been proved to elicit a variety of biological effects through its anti-inflammatory and anti-oxidant properties in the treatment of severe acute pancreatitis and ischemia-reperfusion injury in retina and intestine. However little is known regarding the effect of OCT in ischemic stroke. Here, we designed this study to investigate the protective effect of OCT in ischemic stroke and explore the potential underlying mechanisms. METHODS Male Sprague-Dawley rats were subjected to permanent middle cerebral artery occlusion (pMCAO) and randomly divided into four groups: Sham (sham-operated), MCAO (pMCAO+0.9% saline), OCT-L (pMCAO+OCT 50μg/kg) and OCT-H (pMCAO+OCT 100μg/kg) groups. OCT was administered intraperitoneally immediately after stroke. Neurological deficit scores, infarct volume and brain water content were measured at 24h after stroke. Immunohistochemical staining and western blot were used to analyze the expressions of Nrf2, HO-1 and NF-κB. SOD and MDA were measured by spectrophotometer. RESULTS Compared with MCAO group, OCT significantly alleviated neurological deficit, lessened infarct volume and brain edema (P<0.05), upregulated the expression of Nrf2, HO-1 and SOD (P<0.05), and decreased the expression of NF-κB and MDA (P<0.05). CONCLUSIONS OCT protected the brain against cerebral ischemic damage; this effect may be through upregulation of transcription factor Nrf2, HO-1 and downregulation of NF-κB expression.

Abstract
Aim To investigate the therapeutic effects of fluorouracil (5-Fu) and octreotide (Oct) continuous regional arterial infusion (CRAI,) alone or in combination, was administered in a canine model of severe acute pancreatitis (SAP). Materials and Methods The animals were divided into five groups; group A (Sham), group B (SAP), group C (SAP and 5-Fu), group D (SAP and Oct), and group E (SAP and 5-Fu + Oct). Levels of amylase, α-tumor necrosis factor (TNF-α), blood urea nitrogen (BUN), creatinine, thromboxane B2 and 6-keto- prostaglandin F1α were measured both before and after the induction of SAP. Pathologic examination of the pancreas and kidneys was performed after termination of the study. Results Pathologic changes noted in the pancreas in SAP significantly improved following CRAI with either single or combined administration of 5-Fu and Oct, where combination therapy demonstrated the lowest injury score. All treatment groups had significantly lower levels of serum TNF-α and amylase activity (P<0.05), though only groups D and E had a lower BUN level as compared to group B. The plasma thromboxane B2 level increased in SAP, but the ratio of thromboxane B2/6-keto- prostaglandin F1α decreased in the treatment groups, with the combination therapy (group E) demonstrating the lowest ratio as compared to the other 3 experimental groups (P<0.05). Conclusions The findings in the present study demonstrate an attenuation of SAP in a canine model following CRAI administration with 5-Fu or Oct, alone or in combination.

Abstract
OBJECTIVE To investigate the protecting effects of dexamethasone (DXM), baicalin and octreotide on brain injury of rats with severe acute pancreatitis (SAP) and explore their underlying mechanism. METHODS This experiment was divided into two different parts: (1) In the first part, 90 SAP rats were randomly divided into a model control group and a DXM treated group (n = 45, respectively). (2) In the second part, 135 SAP rats were randomly divided into a model control group, a baicalin treated group and an octreotide treated group (n = 45, respectively). In two different experiments, the same number of normal rats were considered as the sham-operated group (n = 45, respectively). At 3, 6 and 12 h after operation, the pathological changes in the brain were observed. The expression levels of nuclear factor-κB (NF-κB), Bax and Bcl-2 proteins were detected and apoptosis indexes were calculated, using brain tissue microarray section. RESULTS (1) First part: The expression levels of Bax and Bcl-2 were significantly higher in the DXM treated group than those in the model control group at different time points, while the content of NF-κB protein and pathological changes were significantly lower in the treated group than those in the model control group (P < 0.05, P < 0.01 or P < 0.001). But the apoptotic indexes of brain tissue were not significantly different at different time points (P > 0.05). (2) Second part: At all time points after operation, the expression levels of NF-κB in the brain of treated groups were, to varying degrees, significantly lower than those in the model control group while the expression levels of Bcl-2 protein in baicalin and octreotide group were significantly higher than those in model control group (P < 0.01, P < 0.01 and P < 0.05, respectively). At 12 h after operation, the expression level of Bax protein in baicalin treated group was significantly higher than those in model control group and octreotide treated group (P < 0.05 and P < 0.01, respectively). CONCLUSIONS Dexamethasone, baicalin and octreotide can exert protective effects against brain injury in SAP rats mainly through inhibiting the expression of NF-κB protein.

Abstract
To study the protective role of Baicalin on rats thymus with severe acute pancreatitis (SAP). The SAP rats were randomly assigned to the model control, Baicalin treated and Octreotide treated groups. Normal rats were assigned to the sham-operated group. The rat survival rates, pathological changes of thymus, apoptotic indexes and expression levels of NF-kappaB, Bax, Bcl-2, Caspase-3 and P-selectin of all groups were observed and recorded at 3, 6 and 12 h after operation, respectively. Rat survival rates were significantly higher in both Baicalin- and Octreotide-treated groups than those in the model control group at 12 h (P < 0.05). The thymus pathological score was significantly lower in Baicalin treated group than in control group at 3 and 12 h (P < 0.05). The expression of NF-kappaB, Bax and Bcl-2 in thymus tissue was negative in all groups. At 3 h after operation, the staining intensity, positive staining rate and intensity of Caspase-3 protein in the thymuses of the Baicalin treated group were significantly higher than those in the model control group (P < 0.01). At different time points after operation, no marked difference was observed in the staining intensity of P-selectin protein between the Baicalin treated group and the model control group (P > 0.05). At 6 h after operation, the positive staining rate and intensity of P-selectin protein in the Baicalin treated group was significantly lower than those in the model control group (P < 0.05). The apoptotic indexes were significantly higher in treated group than in model control group at 6 h (P < 0.05). Baicalin has a protective role on the thymus of SAP rats, and its effect of decreasing inflammatory mediators level in blood, inhibiting P-selectin expression and inducing apoptosis of thymocytes may involve in the mechanism of its protective role.

Abstract
OBJECTIVE Baicalin reduces the severity of severe acute pancreatitis (SAP) in a rat model. This study was carried out to examine the effect of baicalin on TNF-alpha mRNA, caspase-3 and P-selectin protein expression in the pancreas of rats with SAP. METHODS Rats with SAP were randomly assigned to untreated, baicalin-treated, octreotide-treated and sham-operated group. The TNF-alpha mRNA expression level, caspase-3 and P-selectin protein expression levels of pancreatic tissue were measured 3, 6 and 12 hours after operation. RESULTS The caspase-3 protein expression level was significantly higher in the treated groups than that in the untreated group at 3 hours (p <0.01). P-selectin protein expression level in pancreas of the treated groups was significantly lower than that of the untreated group (p <0.05 or <0.01). TNF-alpha mRNA expression level in pancreas decreased in baicalintreated group while untreated group increased at different time points (p <0.05). CONCLUSION Baicalin increases caspase-3 expression and inhibits TNF-alpha mRNA and P-selectin protein expression in pancreatic tissue of SAP rats.

Abstract
BACKGROUND AND AIMS To explore the protecting effects and mechanisms of dexamethasone on spleen injury in rats with severe acute pancreatitis (SAP). METHODS The rats were randomly divided into a model control group, treated group and sham-operated group. The contents of plasma endotoxin, serum NO, phospholipase A(2) enzyme (PLA(2)) and endothelin-1 (ET-1) were determined. The mortality rate, pathological changes and changes of Bax and Bcl-2 protein expression levels and apoptotic indexes in the spleen of rats were observed in all groups, respectively, at 3, 6 and 12 h after operation. RESULTS Although the survival rate was significantly higher in the treated group than in the model control group, there was no significantly different between them (P > 0.05). The expression levels of Bax and Bcl-2 proteins and apoptotic indexes were significantly higher in the treated group than in the model control group at different time points (P < 0.05 or P < 0.01) while other blood indexes contents and pathological severity scores of spleen were significantly lower in the treated group than in the model control group (P < 0.05, P < 0.01 or P < 0.001). CONCLUSION Dexamethasone can protect spleen from injury during SAP mainly by reducing the content of inflammatory mediators in blood.

METHODS Rats were randomly divided into sham-operated, model control, baicalin-treated and octreotide-treated groups. At 3, 6 and 12 h after operation, the mortality rates of rats, the contents of plasma endotoxin as well as serum NO and ET-1, the pathological changes in multiple organs, and the expression levels of P-selectin protein in each group were observed. RESULTS At 12 h after operation, the mortality rates of rats in treated groups were significantly lower than that in the model control group (P < 0.05), and the pathological severity scores in multiple organs in treated groups were also significantly lower than those in the model control group (P < 0.05). The contents of plasma endotoxin, serum PLA(2) (at 6 and 12 h after operation), ET-1 and NO (at 3 and 12 h after operation) in treated groups were significantly lower than those in the model control group (P < 0.05, P < 0.01 or P < 0.001). In the baicalin-treated group, the expression levels of P-selectin protein in liver (at 3 h after operation), kidney (at 3 and 6 h after operation), pancreas, lung and spleen were significantly lower than those in the model control group (P < 0.01). In the octreotide-treated group, the expression levels of this protein in lung, intestinal mucosa (at 6 and 12 h after operation), lymph nodes (at 3 and 6 h after operation), spleen and thymus were significantly lower than those in the model control group (P < 0.05). Additionally, the products of the staining intensity and positive rate of P-selectin protein in pancreas, spleen (at 3 h after operation), intestinal mucosa (at 6 h after operation), thymus (at 6 h after operation) and lung (at 6 h after operation) in treated groups were significantly lower than those in the model control group (P < 0.05). CONCLUSION Both baicalin and octreotide can exert some protective effects on multiple organs and the former is superior to the latter in protecting pancreas. Furthermore, decreasing the expression levels of P-selectin protein in these organs is one of the possible mechanisms.

Abstract
AIM: To investigate the correlation between the antifibrotic effect of baicalin and serum cytokine production in rat hepatic fibrosis.
METHODS: Forty male Sprague-Dawley rats were divided randomly into four groups: normal control group, model group, baicalin-treated group, and colchicine-treated group. Except for the normal control group, all rats in the other groups were administered with carbon tetrachloride to induce hepatic fibrosis. At the same time, the last two groups were also treated with baicalin or colchicine. At the end of the 8 wk, all animals were sacrificed. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), transforming growth factor (TGF)-β1, tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10 were measured. Liver index, hepatic hydroxyproline content and the degree of liver fibrosis were also evaluated.
RESULTS: The levels of ALT, AST and liver index in the baicalin-treated group were markedly lower than those in the model group (ALT: 143.88 ± 14.55 U/L vs 193.58 ± 24.35 U/L; AST: 263.66 ± 44.23 U/L vs 404.37 ± 68.29 U/L; liver index: 0.033 ± 0.005 vs 0.049 ± 0.009, P < 0.01). Baicalin therapy also significantly attenuated the degree of hepatic fibrosis, collagen area and collagen area percentage in liver tissue (P < 0.01). Furthermore, the levels of serum TGFβ1, TNF-α and IL-6 were strikingly reduced in the baicalin-treated group compared with the model group, while the production of IL-10 was up-regulated: (TGF-β1: 260.21 ± 31.01 pg/mL vs 375.49 ± 57.47 pg/mL; TNF-α: 193.40 ± 15.18 pg/mL vs 260.04 ± 37.70 pg/mL; IL-6: 339.87 ± 72.95 pg/mL vs 606.47 ± 130.73 pg/mL; IL-10: 506.22 ± 112.07 pg/mL vs 316.95 ± 62.74 pg/mL, P < 0.01).
CONCLUSION: Baicalin shows certain therapeutic effects on hepatic fibrosis, probably by immunoregulating the imbalance between profibrotic and antifibrotic cytokines.

Abstract
OBJECTIVES To investigate the effect of bacailin on inflammatory mediators and microcirculation disturbance in severe acute pancreatitis (SAP) rats and explore its therapeutic mechanism. METHODS The rats were randomly divided into SAP group, baicalin-treated group and sham operated group. At 3, 6, and 12 hours after operation, we examined the mortality rate of rats, ascites volume, and pancreatic pathological changes in each group and determined the contents of inflammatory mediators in blood as well as the changes in blood viscosity. RESULTS Compared with SAP group, treatment with baicalin is able to improve the pathological damage of the pancreas, reduce the contents of multiple inflammatory mediators in blood, decrease the amount of ascitic fluid, and reduce the mortality rates of SAP rats. The low-shear whole blood viscosity in baicalin-treated group (at 3 hours) as well as the high-shear and low-shear whole blood viscosity in baicalin-treated group (at 12 hours) were significantly lower than that in SAP group. CONCLUSIONS Baicalin has good prospects in the treatment for SAP because it can exert therapeutic effects on this disease through inhibiting the production of inflammatory mediators, decreasing blood viscosity, improving microcirculation, and mitigating the pathological damage of the pancreas.

Abstract
To observe the protective effects of Salvia miltiorrhizae injection on multiple organs of rats with SAP or OJ. Two hundred eighty-eight rats were used for SAP-associated experiments and OJ-associated experiments. The rats were randomly divided into sham-operated, model control and treated group. According to the different time points after operation, the SAP rats in each group were subdivided into 3, 6 and 12 h groups while the OJ rats were divided into 7, 14, 21 and 28 days groups. The mortality rates, pathological changes and ICAM-1 (only in lung), TLR4 (only in liver), Bax and NF-kappaB proteins expression in multiple organs (liver, kidney, lung, intestinal mucosa, spleen, thymus and lymph nodes) were observed, respectively. The mortality rates of treated groups decreased in both SAP and OJ experiments. Compared to model control group, the pathological changes can be seen in treated groups including; (1) the pathological changes of multiple organs in SAP and OJ experiments were improved, the pathological severity scores of kidney (at 6 h), intestinal mucosa (at 12 h), spleen (at 6 and 12 h), thymus (at 3 and 6 h) and lymph nodes (at 3 and 6 h) in SAP experiment and of liver (on 21 and 28 days), lung (21 days), intestinal mucosa (on 21 and 28 days) and spleen (on 21 and 28 days) in OJ experiment significantly declined (P < 0.05 or P < 0.01); (2) the positive rate of Bax protein in pancreas (at 3 h) and liver (on 6 and 12 h) in SAP experiment and in liver (on 28 days), kidney (on 21 days), and thymus (on 28 days) in OJ experiment were significantly lower (P < 0.05 or P < 0.01); (3) the positive rate of NF-kappaB in liver (at 12 h) and kidney (at 6 h) in SAP experiment and in liver (on 21 days), kidney (on 28 days), intestinal mucosa (on 28 days) and thymus (on 14 days) in OJ experiment significantly decreased (P < 0.05). (4) the positive rate of ICAM-1 in lungs (at 12 h) in SAP experiment was significantly less (P < 0.05). Salvia miltiorrhizae injection can protect multiple organs of SAP or OJ rats and inhibit the expression of ICAM-1, TLR4, NF-kappaB and regulate Bax proteins. Salvia miltiorrhizae may relieve the inflammation response and enhance the immunity function of SAP and OJ rats.

Abstract
The lipophilic flavonoid glycoside baicalin from the traditional oriental herb Scutellaria baicalensis Georgi (logP = 1.27, pK(a1) = 7.6, pK(a2) = 10.1 as determined at 25 degrees C in 0.1 M NaCl) is found to be as reducing (0.39 V vs NHE, reversible two-electron oxidation by CV at pH 7.4) as other catechol flavonoids but a poor radical scavenger (TEAC = 1.12, pH 7.4) and a poor antioxidant against free radical initiated lipid oxidation in liposomes. However, this compound is able to regenerate beta-carotene (beta-Car) from beta-Car(*+) with a second-order rate constant of (5.6 +/- 0.5) x 10(9) L mol(-1) s(-1) in the methanol/chloroform binary solvent (1:9, v/v) and, more importantly, to exhibit a prominent synergistic effect with beta-Car against the lipoxidation induced by AMVN-derived peroxyl radical in liposomal membrane. Thus, baicalin by itself is not an effective antioxidant, but it becomes one via interaction with beta-Car. The radical scavenging and antilipoxidation properties of baicalin are discussed in terms of its physicochemical properties and molecular structures.

Abstract
PURPOSE we aim to explore the protective effects of Salvia miltiorrhizae injection on multiple organs of obstructive jaundice (OJ) rats through observing the impact of this injection on the pathological alterations in these organs and the contents of endotoxin, PLA(2), and TNF-alpha in the blood. METHODS A total of 90 mice were randomly divided into sham-operated group, model-control group, and Salvia miltiorrhizae-treated group (n = 30). According to the duration of postoperative administration, each group was further divided into two subgroups, namely, 21 d subgroup (consecutive administration for 21 d, n = 15) and 28 d subgroup (consecutive administration for 28 d, n = 15). After administration, the pathological alterations in multiple organs were observed and the contents of endotoxin, PLA(2), and TNF-alpha in the blood were determined. RESULTS Compared to model control group, the number of dead rats in treated group decreased though there was no statistical difference between the two groups. The pathological alterations in the liver, kidney, and spleen in treated group showed varying degrees of mitigation. At all time points, the contents of plasma endotoxin declined significantly. On day 28, plasma PLA(2) content in treated group was significantly lower than that in model-control group. CONCLUSION Salvia miltiorrhizae injection is able to obviously reduce the contents of inflammatory mediators in the blood of OJ rats and exert some protective effects on multiple organs of these rats.

Abstract
OBJECTIVE To investigate the therapeutic effects and mechanism of salvia miltiorrhizae in the treatment of severe acute pancreatitis (SAP) or obstructive jaundice (OJ). METHODS SAP rat models were prepared and randomly divided into the model control group and treated group. The sham-operated group was also set. At 3 h, 6 h and 12 h after operation, the mortality rate, the pathological changes in the liver, the contents of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum, the expression levels of Bax and NF-kappaB p65 proteins in the liver, and the apoptosis index of hepatic cells in SAP rats in each group were observed. On days 7, 14, 21 and 28 after operation, the above parameters and the contents of TBILI (total billirubin), DBILI (direct bilirubin) and r-GT (r-glutamyl transpeptidase) in serum in OJ rats were observed. RESULTS The contents of serum ALT (at 6 h and 12 h after operation) and AST (at 3 h and 12 h after operation) as well as the staining intensity of NF-kappaB p65 protein (at 12 h after operation) in the liver of SAP rats in the treated group were significantly lower than those in model control group (all P < 0.01). The pathological severity scores (on 21 d and 28 d after operation) in the liver, the contents of serum ALT (on 14 d and 21 d after operation), AST (on 21 d after operation), TBILI (on 21 d and 28 d after operation), DBILI (on 28 d after operation) and r-GT (on 21 d after operation), and the apoptosis index of hepatic cells in OJ rats in treated group were significantly lower than those in model control group (all P < 0.05). The positive rates of Bax protein (on 28 d after operation) in treated group was significantly lower than model control group (P < 0.05). CONCLUSIONS Salvia miltiorrhizae is able to improve the liver function of SAP or OJ rats, suppress the expression of NF-kappaB p65 protein in the liver of SAP rats, and inhibit apoptosis in OJ rats, thereby showing some protective effects on the liver of SAP or OJ rats.

Abstract
We investigated the effects of Baicalin and Octreotide on the levels of endotoxin and TNF-alpha in blood and the effects of apoptotic changes in multiple organs of SAP rats, and explored the underlying therapeutic mechanisms of Baicalin and Octreotide. In this study, 135 SAP rats were randomly divided into model control, Baicalin treated and Octreotide treated group (n = 45), respectively, the same number of normal rats were included in sham-operated group (n = 45). The above-mentioned groups were further subdivided into 3, 6 and 12 h subgroups, respectively (15 rats in each subgroup). At 3, 6 and 12 h after operation, the mortality rate of rats, endotoxin and TNF-alpha levels in blood as well as the pathological severity scores, expression levels of Bax protein and apoptosis indexes in multiple organs were determined. Compared to model control group (1),both drugs can relieve the pathological injuries of multiple organs and decrease significantly the levels of endotoxin and TNF-alpha in blood and the mortality rate of rats in treated groups (P < 0.05 or P < 0.01); (2) the expression of Bax protein was upregulated in pancreas, lung, intestinal mucosa (P < 0.05 or P < 0.01) but downregulated in spleen and lymph nodes (P < 0.001 and P < 0.05, respectively) in Baicalin treated group; The apoptosis indexes significantly increased in pancreas, intestinal mucosa, lymph nodes and spleen (P < 0.05 or P < 0.01). (3) the expression of Bax protein was upregulated in pancreas and lung but downregulated in spleen and lymph nodes (P < 0.05 or P < 0.01) in Octreotide treated group; The apoptosis indexes significantly increased in lymph nodes and spleen in Octreotide treated group (P < 0.05 or P < 0.01). Baicalin and Octreotide share a similar therapeutic efficacy in the treatment of SAP via a mechanism that is associated with inhibiting the levels of TNF-alpha in blood and induce apoptosis in multiple organs.

Abstract
To observe the influence of Baicalin and Octreotide on liver and kidney of rats with severe acute pancreatitis (SAP) and discuss the related mechanism. SAP rats were randomly divided into model control, Baicalin treated and Octreotide treated group (n = 45). The same number of normal rats were included in sham-operated group (n = 45). In all groups, the mortality rate, pathological changes as well as expression levels of NF-kappaB p65 and P-selectin protein in liver and kidney were observed at 3, 6 and 12 h after operation. The survival rate of treated group was 100% at 12 h significantly higher than that of model control group (P < 0.05). The pathological changes of liver and kidney in treated groups were alleviated to different degrees, the NF-kappaB protein expression levels and pathological severity scores in liver and kidney of treated groups were significantly lower than those of model control group (P < 0.05 or P < 0.001). The hepatic P-selectin protein expression level in Baicalin treated group was significantly lower than that of model control group at 3 h (P < 0.01), and renal P-selectin expression level in Baicalin treated group at 3 and 6 h were significantly lower than those of model control group and Octreotide treated group (P < 0.01). (1) Early treatment with Baicalin or Octreotide have obvious protecting effects on liver and kidney injuries in SAP with their mechanisms associated to inhibiting NF-kappaB and P-selectin expression of liver and kidney. (2) Comparing the pharmacologic effects of Octreotide and Baicalin, we believe Baicalin as a new drug with its protecting effects on liver and kidney of SAP rats similar to Octreotide is worth further studying. (3) The advantages of tissue microarrays in pathological examination include time and energy saving and highly efficient. But the restriction of small diameter weakens the representation of tissues to various extents, which may lead to the deviation of analysis.

Abstract
BACKGROUND To investigate the effects of Baicalin and Octreotide on inflammatory mediators and pancreatic acinar cells apoptosis of rats with severe acute pancreatitis (SAP). METHODS SD rats were randomly divided into sham operated group (I group), model control group (II group), Baicalin treated group (III group) and Octreotide treated group (IV group). Each group was also divided into subgroup of 3, 6 and 12 h (n = 15). The mortality rate, ascites/body weight ratio as well as the level of endotoxin, NO and ET-1 in blood were measured. The pathological severity score of pancreas, apoptotic indexes, and expression levels of Bax and Bcl-2 proteins in each group were investigated. RESULTS The survival rate of III and IV group has a significant difference compared with II group (P(12 h) < 0.05). The ascites volume, contents of inflammatory mediators in blood and pathological severity score of pancreas of III and IV group declined at different degrees compared to II group (P < 0.05, P < 0.01 or P < 0.001). Apoptotic index in III group was significantly higher than that in II group at 3 and 6 h (P(3, 6 h) < 0.05). Apoptotic index in IV group was significantly higher than that in II group at pancreatic tail at 6 h (P(6 h) < 0.05). Expression level of Bax in III group was significantly higher than that in II group (pancreatic head P(3 h,6 h) < 0.01, pancreatic tail P(3 h) < 0.001). CONCLUSIONS Compared with Octreotide in the treatment of SAP, the protective mechanisms of Baicalin include reducing the excessive inflammatory mediators' release, inducing the pancreatic acinar cells apoptosis.

Abstract
AIM: To investigate the protective effects and mechanisms of Baicalin and Octreotide on hepatic injury in rats with severe acute pancreatitis (SAP).
METHODS: The SAP rat models were prepared and randomly assigned to the model control group, Baicalin treated group, and Octreotide treated group while other healthy rats were assigned to the sham-operated group. Rat mortality, levels of ALT, AST, liver and pancreas pathological changes in all groups were observed at 3, 6 and 12 h after operation. Tissue microarray (TMA) sections of hepatic tissue were prepared to observe expression levels of Bax, Bcl-2 protein and Caspase-3, and changes of apoptotic indexes.
RESULTS: Rat survival at 12 h, expression levels of Bax, Caspase-3 protein and apoptotic indexes of liver were all significantly higher in treated groups than in model control group. While the liver and pancreas pathological scores, contents of ALT, AST, and expression levels of Bcl-2 protein were all lower in treated groups than in the model control group.
CONCLUSION: Both Baicalin and Octreotide can protect rats with SAP by decreasing the contents of ALT, AST and expression levels of Bcl-2 protein, and improving the expression levels of Bax protein, Caspase-3 protein, and inducing apoptosis.

P-Selectin, Bax, Bcl-2, and Caspase-3 protein
expression levels as well as apoptotic index were observed in all
groups, respectively, at 3 hours, 6 hours, and 12 hours after
operation.
Results. The survival rate of model group was less
than treated groups at 12 hours, difference was significant. The
contents of some inflammatory indexes of the treated groups were
lower than those of the model group to various degrees at
different time points. The pathological myocardial changes under
light microscope were milder in treated groups than in model
group. The changes of
NF-κB,
P-Selectin, Bax, Bcl-2, and Caspase-3 protein expression levels in
all groups were different. There was only a case of myocardial
cell apoptosis in an Octreotide-treated group at 6 hours.
Conclusion. Baicalin and Octreotide have protecting
effects on heart injury of rats with SAP.

Abstract
AIM: To investigate the effect of Chaiqinchengqi decoction (CQCQD) on sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) mRNA expression of pancreatic tissues in acute pancreatitis (AP) rats.
METHODS: Thirty Sprague-Dawley (SD) rats were randomized into control group, AP group and CQCQD group (n = 3 × 10). The rats in the CQCQD group were intragastrically administered with CQCQD (10 mL/kg every 2 h) after induction of AP by intraperitoneal injection of caerulein (50 &mgr;g/kg.h × 5) within 4 h. At 6 h after the induction of AP model, pancreatic tissues were collected for the pathological observation, mRNA extraction for determination of SERCA1 and SERCA2 mRNA expression or pancreatic acinar cell isolation for measurement of fluorescence intensity (FI) of intracellular calcium ion concentration [Ca2+]i.
RESULTS: There was no expression of pancreatic SERCA1 mRNA in the control group and the AP group. The expression of pancreatic SERCA2 mRNA in the AP group was down-regulated (expression ratio = 0.536; P = 0.001) compared with the control group, while that in the CQCQD group was up-regulated (expression ratio = 2.00; P = 0.012) compared with AP group. The FI of intracellular [Ca2+] of pancreatic acinar cells in the AP group (138.2 ± 23.1) was higher than the C group (111.0 ± 18.4) and the CQCQD group (118.7 ± 15.2 ) (P < 0.05) and the pancreatic pathological score in the CQCQD group was lower than that in the AP group (5.7 ± 1.9 vs 9.2 ± 2.7, P < 0.05).
CONCLUSION: CQCQD can up-regulate the expression of SERCA2 mRNA of pancreatic tissues, reduce intracellular calcium overload and relieve pancreatic tissue lesions.
