Objective To investigate the efficiency of combining traditional Chinese medicine with western medicine in the treatment of severe acute pancreatitis (SAP). Methods The clinical results of sixty three cases of SAP of non-operative treatment with injection of Salia miltorrhizae composita, and oral or gastric tube feeding of decoction Qing-Yi-Tang were retrospectively studied. Results Thirty four cases were categorised as SAP Ⅰ grade, and 29 cases as SAP Ⅱ grade. A variety of complications occurred in 19 cases (30.16%), 3 patients died (4.76%), and 4 patients developing abscess of pancreas (6.35%) which had to be operated on.Conclusion The individualization principle on the basis of cause and clinical stage of the disease should be stressed in treating SAP. The patients who had complication needing to be operated on should be timely performed. There is a good efficiency in the treatment of SAP with the traditional Chinese medicine combining with western medicine.
Objective To investigate the changes of expression of zonula occludens-1(ZO-1) in rats with severe acute pancreatitis (SAP), and to study the relationship between the ZO-1 protein and microvascular injury in rats with SAP. Methods Forty-eight Wistar rats were randomly divided into sham-operation (SO) group and SAP group, each group enrolled 24 rats. Pancreas of rats in SO group were flipped only after laparotomies, but rats of SAP group were injected with 5% sodium taurocholate by retrograding cholangiopancreatography micro pump to produce the SAP model. At 6, 12, and 24 hours after operation, 8 rats were sacrificed to get abdominal aortic blood for testing the levels of peripheral blood amylase, trypsin, interleukin-8(IL-8), tumor necrosis factor-α(TNF-α), and ZO-1 protein. At the same time, pancreatic tissues were got to perform HE staining and immunohistochemical staining for observation of the pathological changes and the expression of ZO-1 protein respectively. Results Compared with SO group at the same time, the levels of peripheral blood amylase, trypsin, IL-8, TNF-α, and ZO-1 protein were all higher in SAP group (P < 0.05). The level of amylase in SAP-24 hours group was higher than those of 6 hours group and 12 hours group(P < 0.05), the levels of trypsin, IL-8, and ZO-1 protein in SAP group increased over time (P < 0.05), but levels of TNF-αin 3 time points of SAP group did not differ with each other significantly(P > 0.05). Results of regression showed that in the SAP group, the level of ZO-1 protein in serum was significantly positive correlated with pathological score of pancreatic tissue(b=0.96, P < 0.05), levels of serum amylase(b=0.87, P < 0.05), trypsin(b=0.72, P < 0.05), and serum IL-8 (b=0.69, P < 0.05), but was not significantly correlated with level of TNF-α(P > 0.05). HE staining results showed that damage of pancreatic tissues became worse over time in SAP group, and the pathological score of SAP-6 hours group was lower than those of 12 hours group and 24 hours group (P < 0.05). Immunohistochemical staining results showed that, in SAP group, with the extension of time, the number of ZO-1 protein granules in pancreatic acinar cells and capillary wall reduced, and expressed in capillaries discontinuously. Conclusion During the course of SAP, the concentration of serum ZO-1 protein increase, but its expression in the pancreatic tissue degrade, which is closely associated with microvascular injury and progression of pancreatic tissues.
The purpose of this study was to determine the contribution of endotoxin (ET) in ocurrence and progression of acute pancreatitis (AP). The results indicated that correlation of ET changes with multiple organ damage in AP. The degree of ET elevation correlated well with the severty of AP. The level of plasma ET of severe AP patients was much higher than that of mild AP patients (Ｐ＜0.05). The chance of multiple organ damage got greater while the plasma ET level got higher. Moreover, the severety change of severe AP correlated with the change of plasma ET level. In other words, the ET level was reduced while the disease was recovering, elevated while it was becoming worse and maintained high level in dead cases. We think that plasma ET level can be used as a reference for differenciating mild AP with severe AP and a predictor for the prognosis of AP.

【Abstract】Objective To study the influence of early hemofiltration on plasma concentrations of proinflammatory cytokines TNF-α and IL-1β and their transcription levels in severe acute pancreatitis (SAP) pigs. Methods The model of SAP was induced by retrograde injection of artificial bile into pancreatic duct in pigs. Animals were divided randomly into two groups: SAP hemofiltration treatment group (HF group, n=8) and SAP no hemofiltration treatment group (NHF group, n=8). TNF-α and IL-1β plasma concentrations were measured by ELISA. Their transcription levels in the tissues of pancreas, liver and lung were assayed by semi-quantitative reverse transcription polymerase chain reaction. Results After hemofiltration treatment, the plasma concentrations of TNF-α and IL-1β increased gradually but were lower than those of NHF group at the same time spot 〔at 6 h after hemofiltration treatment, (618±276) pg/ml vs (1 375±334) pg/ml and (445±141) pg/ml vs (965±265) pg/ml, P＜0.01〕. At 6 h after hemofiltration treatment, the transcription levels of TNF-α and IL-1β in tissues of pancreas, liver and lung were lower than in NHF group (57.8±8.9 vs 85.7±17.4, 48.0±8.1 vs 78.1±10.2, 46.2±9.6 vs 82.4±10.5; 55.9±9.0 vs 82.2±15.7, 40.6±9.2 vs 60.0±10.6, 35.7±9.8 vs 58.1±9.3, P＜0.01). Conclusion Early hemofiltration can reduce TNF-α and IL-1β plasma concentrations and transcription levels in SAP pigs.
ObjectiveTo explore the mechanism of liver capillary permeability in rats with severe acute pancreatitis (SAP). MethodsTotally 40 healthy Sprague-Dawley (SD) rats were randomly divided into two groups: sham operation (SO) group and SAP group, SAP group were divided into four subgroups according to sampling time (3 h， 6 h, 12 h， and 24 h). The model was established by injecting 5% sodium taurocholate retrogradely into pancreaticobiliary ducts. The changes of tumor necrosis factor-α (TNF-α), pathohistology, and tissue moisture content were compared among different groups. Liver occludin protein expression was analyzed by immunohistochemistry method, and occludin mRNA was measured by RT-PCR. ResultsThere was no significant pathological changes of liver tissue in the SO group. Typical pathological changes of SAP， such as interstitial edema, vasodilatation, infiltration of inflammatory cells, were found in the SAP group. TNF-α level and tissue moisture content of each phase increased gradually, and the highest level appeared at 24 h within the observing period. The two above indicators at different time point in subgroups were significantly different from each other and higher than those in the SO group (Plt;0.05)． In the SAP group, the expression of occludin and it’s mRNA began to decrease at 3 h to the bottom at 6 h and rebounced significantly at 12 h, 24 h compared with those at 6 h (Plt;0.05), but still lower than those in the SO group (Plt;0.05). ConclusionUpregulation in TNF-α and subsequent downregulation in occludin protein and mRNA maybe bly related to the severe liver capillary permeability in rats with SAP.
Objective To explore the effect of renal microcirculation following severity acute pancreatitis （SAP） on renal injury and to explore the protection effect of urokinase on them. Methods A total of 192 Wistar rats were randomized divided into normal control group， SAP group， and urokinase group， then rats of 3 groups were sub-divided into 2， 6， 12， and 24 hours group， each group enrolled 16 rats. Of the 16 rats in each subgroup， 8 rats underwent blood flow of renal test， other 8 rats were sacrificed to get blood samples and to perform histopathological examination. The rat models of SAP were established by retrograde injecting with 5% sodium taurocholate into the cholangiopancreatic duct. Radioactive biomicrosphere technique was used to measure the blood flow of renal， levels of plasma thromboxane B2（TXB2） and 6-keto-prostaglandin F1α （6-Keto-PGF1α） were tested by the TXB2 kit and 6-Keto-PGF1α kit， and histopa-thological changes of renal tissues were observed by using HE staining. Results Compared with normal control group at the same time point， the blood flow of renal were lower （P＜0.05）， activity ratio of TXB2 to 6-Keto-PGF1α were higher（P＜0.01）， and the histopathological injury were worse （P＜0.01） in rats of SAP group and urokinase group. Compared with SAP group， the blood flow of renal at 2， 6， and 12 hours in urokinase group were higher （P＜0.01）， the activity ratios of TXB2 to 6-Keto-PGF1α were lower （P＜0.01）， and the histopathological injury were lighter （P＜0.05） in all the 4 time points of urokinase group. Conclusions The renal microcirculation dysfunction and increase of activity ratio of TXB2 to 6-Keto-PGF1α may play an important role in renal injury following SAP in early stage. Urokinase can protect the renal from such injuries.
