Effect of combined therapy of Yinchenhao Chengqi decoction and endoscopic sphincterotomy for endotoxemia in acute cholangitis

AIM To evaluate the therapeutic mechanism of Yinchenhao Chengqi (YCHCQ) decoction (containing mainly Herba Artemisia capillaris) combined with endoscopic sphincterotomy (EST) for endotoxemia (ETM) in acute cholangitis.METHODS Twenty-one cases of acute cholangitis with ETM were divided randomly into two groups: group A, 10 patients treated with YCHCQ decoction combined with EST, group B, 11 patients treated with EST. The incidence rate of ETM, plasmic ET, serum superoxide dismutase (SOD) activity, malonyldialdehyde (MDA), complement C3 and C-reactive protein (CRP) were studied respectively.RESULTS The ET level of group A (35.92ng/L±8.30ng/L) was significantly reduced after 7 days of treatment (P＜0.05) in contrast to that of group B (47.8ng/L±11.62ng/L), so did the level of MDA and CRP. But the SOD activity and C3 level in group A increased significantly (P＜0.05).CONCLUSION YCHCQ decoction combined with EST had a beneficial effect for ETM in acute cholangitis.INTRODUCTIONEndotoxemia (ETM) is one of the most important physiopathologic causes of acute cholangitis and it is the trigger of cytokines and inflammatory factors. In recent studies it has been found that Yinchenhao Chengqi (YCHCQ) decoction has a beneficial effect on ETM in acute cholangitis. With the development of endoscopic surgery, endoscopic sphincterotomy (EST) has become an effective replacement for some operations in the treatment of acute cholangitis[1]. The effect of YCHCQ decoction combined with EST on ET, oxygen free radical and complement C3 was observed in order to find out its therapeutic mechanism.

The influence of intestine-based treatment using Xuan Bai Cheng Qi Tang on the concentration of trace elements in the main organs of COPD rats

Objective:To test two theories from traditional Chinese medicine:'exterior -interior relationship between the lung and large intestine' and 'treating from the intestine principle for lung disorders'.The influence of intestine-based treatment using Xuan Bai Cheng Qi Tang (XBCQT) on the concentration of three trace elements-copper (Cu),zinc (Zn),and manganese (Mn)-was observed in the tissues of the lung,small intestine,large intestine,and stomach of rats suffering from chronic obstructive pulmonary disease (COPD).Methods:Thirty-five male Wistar rats were divided randomly and equally into five groups:control;model;Fei treatment (A);Chang treatment (B);and Fei-Chang treatment (C).A rat model of COPD was prepared by tracheal injection of lipopolysaccharide plus exposure to cigarette smoke.Treatments with medicinal herbs started day-22 of administration and exposure to cigarette smoke for 7 days.The control group and model group were administered physiologic (0.9%) saline solution via the stomach.After 7 days of intervention,the tissues of the lung,small intestine,large intestine,and stomach were removed.Inductively coupled plasma-atomic emission spectroscopy was used to detect the levels of Cu,Zn,and Mn in those tissues.Results:Compared with the control group,the Cu concentration in the tissues of the small intestine,large intestine,and stomach increased significantly in the model group (P <.05);the Mn concentration in the tissues of the lung,large intestine,and stomach increased significantly in the model group (P <.05);the Zn concentration in the tissues of the lung and large intestine decreased significantly in the model group (P <.05).In comparison of the model group:the Cu concentration in the tissues of the lung and large intestine decreased significantly in the B group (P <.05);the Mn concentration in the tissues of the lung,small intestine,and large intestine decreased significantly in the B group (P <.05);the Zn concentration in the tissues of the lung,small intestine,and large intestine increased significantly in the B group (P <.05).For the A group versus C group comparison,the Zn concentration in the tissues of the small intestine and stomach increased significantly in the latter (P <.05).Conclusion:This study showed that 'treating from the intestine' using Xuan Bai Cheng Qi Tang and its modified formulae can regulate the concentration of trace elements in the main organs of COPD rats.This may be one of the mechanisms for intestine-based treatment for COPD.

Effects of Chai-Qin-Cheng-Qi Decoction on cefotaxime in rats with acute necrotizing pancreatitis

AIM:To investigate the effect of Chai-Qin-Cheng-Qi Decoction(CQCQD)on cefotaxime(CTX)concentration in pancreas of rats with acute necrotizing pancreatitis (ANP). METHODS:Sixty healthy male Sprague-Dawley rats were divided randomly into an ANP group(ANP model +CTX,n=20),treatment group(ANP model+CTX +CQCQD,n=20)and control group(normal rats+ CTX,n=20).ANP models were induced by retrograde intraductal injection of 3.5%sodium taurocholate (1 mL/kg),and the control group was injected intraductally with normal saline.All rats were injected introperitoneally with 0.42 g/kg CTX(at 12-h intervals for a continuous 72 h)at 6 h after intraductal injection. Meanwhile,the treatment group received CQCQD (20 mL/kg)intragastrically at 8-h intervals,and the ANP and control group were treated intragastrically with normal saline.At 15 min after the last CTX injection,blood and pancreas samples were collected for the determination of CTX concentration using validated high-performance liquid chromatography. Pathological changes and wet-to-dry-weight(W/D) ratio of pancreatic tissue were examined. RESULTS:Serum CTX concentrations in three groups were not significantly different.Pancreatic CTXconcentration and penetration ratio were lower in ANP group vs control group(4.4±0.6μg/mL vs 18.6± 1.7μg/mL,P=0.000;5%vs 19%,P=0.000),but significantly higher in treatment group vs ANP group (6.4±1.7μg/mL vs 4.4±0.6μg/mL,P=0.020;7% vs 5%,P=0.048).The histological scores and W/D ratio were significantly decreased in treatment group vs ANP and control group. CONCLUSION:CQCQD might have a promotive effect on CTX concentration in pancreatic tissues of rats with ANP.

Pharmacokinetics and pharmacodynamics of Da-Cheng-Qi decoction in the liver of rats with severe acute pancreatitis

AIM To explore the pharmacokinetics and pharmacodynamics of Da-Cheng-Qi decoction (DCQD) in the liver of rats with severe acute pancreatitis (SAP) based on an herbal recipe tissue pharmacology hypothesis. METHODS Healthy male Sprague-Dawley rats were randomly divided into a sham operation group (SOG); a model group (MG); and low-, median- and high-dose treatment groups (LDG, MDG, and HDG, respectively). Different dosages (6, 12 and 24 g/kg for the LDG, MDG, and HDG, respectively) of DCQD were administered to the rats with SAP. The tissue concentrations of aloeemodin, rhein, emodin, chrysophanol, honokiol, rheo chrysophanol, magnolol, hesperidin, naringenin and naringin in the liver of the treated rats were detected by high-performance liquid chromatography tandem mass spectrometry. Alanine transaminase (ALT) and aspartate transaminase (AST) in serum, inflammatory mediators in the liver and pathological scores were evaluated. RESULTS The major components of DCQD were detected in the liver, and their concentrations increased dose-dependently. The high dose of DCQD showed a maximal effect in ameliorating the pathological damages, decreasing the pro-inflammatory mediators tumor necrosis factor-a and interleukin (IL)-6 and increasing anti-inflammatory mediators IL-4 and IL-10 in the liver. The pathological scores in the pancreas for the MG were significantly higher than those for the SOG (P < 0.05). DCQD could reduce the pathological scores in the pancreas and liver of the rats with SAP, especially in the HDG. Compared to the SOG, the ALT and AST levels in serum were higher in the MG (P < 0.05), while there was no statistical difference in the MG and HDG. CONCLUSION DCQD could alleviate liver damage by altering the inflammatory response in rats with SAP based on the liver distribution of its components.

Optimal timing for the oral administration of DaCheng-Qi decoction based on the pharmacokinetic and pharmacodynamic targeting of the pancreas in rats with acute pancreatitis

AIM To identify the optimal oral dosing time of Da-Cheng-Qi decoction(DCQD) in rats with acute pancreatitis(AP) based on the pharmacokinetic and pharmacodynamic parameters.METHODS First, 24 male Sprague-Dawley rats were divided into a sham-operated group [NG(a)] and three model groups [4 h G(a), 12 h G(a) and 24 h G(a)]. The NG(a) and model groups were administered DCQD(10 g/kg.BW) intragastrically at 4 h, 4 h, 12 h and 24 h, respectively, after AP models induced by 3% sodium taurocholate. Plasma samples were collected from the tails at 10 min, 20 min, 40 min, 1 h, 2 h, 4 h, 8 h, 12 h and 24 h after a single dosing with DCQD. Plasma and pancreatic tissue concentrations of the major components of DCQD were determined by high-performance liquid chromatography tandem mass spectroscopy. The pharmacokinetic parameters and serum amylase were detected and compared. Second, rats were divided into a sham-operated group [NG(b)] and three treatment groups [4 h G(b), 12 h G(b) and 24 h G(b)] with three corresponding control groups [MG(b)s]. Blood and pancreatic tissues were collected 24 h after a single dosing with DCQD. Serum amylase, inflammatory cytokines and pathological scores of pancreatic tissues were detected and compared.RESULTS The concentrations of emodin, naringin, honokiol, naringenin, aloe-emodin, chrysophanol and rheochrysidin in the 12 h G(a) group were higher than those in the 4 h G(a) group in the pancreatic tissues(P < 0.05). The area under the plasma concentration-time curve from time 0 to the time of the last measurable concentration values(AUC0→t) for rhein, chrysophanol, magnolol and naringin in the 12 h G(a) group were larger than those in the 4 h G(a) or 24 h G(a) groups. The 12 h G(a) group had a higher Cmax than the other two model groups. The IL-10 levels in the 12 h G(b) and 24 h G(b) groups were higher than in the MG(b)s(96.55 ± 7.84 vs 77.46 ± 7.42, 251.22 ± 16.15 vs 99.72 ± 4.7 respectively, P < 0.05), while in the 24 h G(b) group, the IL-10 level was higher than in the other two treatment groups(251.22 ± 16.15 vs 154.41 ± 12.09/96.55 ± 7.84, P < 0.05). The IL-6 levels displayed a decrease in the 4 h G(b) and 12 h G(b) groups compared to theMG(b)s(89.99 ± 4.61 vs 147.91 ± 4.36, 90.82 ± 5.34 vs 171.44 ± 13.43, P < 0.05). CONCLUSION Late-time dosing may have higher concentrations of the most major components of DCQD, with better pharmacokinetics and pharmacodynamics of antiinflammation than early-time dosing, which showed the late time to be the optimal dosing time of DCQD for AP.

Identification of active compound combination contributing to anti-inflammatory activity of Xiao-Cheng-Qi Decoction via human intestinal bacterial metabolism

Human intestinal bacteria play an important role in the metabolism of herbal medicines, leading to the variations in their pharmacological profile. The present study aimed to investigate the metabolism of Xiao-Cheng-Qi decoction(XCQD) by human intestinal bacteria and to discover active component combination(ACC) contributing to the anti-inflammatory activity of XCQD. The water extract of XCQD was anaerobically incubated with human intestinal bacteria suspensions for 48 h at 37 °C. A liquid chromatography-hybrid quadrupole time-of-flight mass spectrometry(LC-Q-TOF/MS) method was performed for identification of the metabolites. In addition, the anti-inflammatory effects of XCQD and biotransformed XCQD(XCQD-BT) were evaluated in vitro with cytokines in RAW264.7 cells induced by lipopolysaccharide(LPS). A total of 51 compounds were identified in XCQD and XCQD-BT. Among them, 20 metabolites were proven to be transformed by human intestinal bacteria. Significantly, a combination of 14 compounds was identified as ACC from XCQD-BT, which was as effective as XCQD in cell models of inflammation. In conclusion, this study provided an applicable method, based on intestinal bacterial metabolism, for identifying combinatory compounds responsible for a certain pharmacological activity of herbal medicines.

Modified Da-Cheng-Qi Decoction reduces intra-abdominal hypertension in severe acute pancreatitis： a pilot study

Background Intra-abdominal hypertension （IAH） is a recognized prognostic marker for severity of severe acute pancreatitis （SAP） and has a strong impact on the clinical course of SAP. Previous studies indicate that a Da-Cheng-Qi Decoction （DCQD） is beneficial in the treatment of SAP. The purpose of this study was to evaluate the effect of modified DCQD on IAH in patients with SAP. Methods Between January 2008 and December 2008, 42 patients from the West China Hospital were randomized into either the DCQD or control group （n=21 in each group）. Mortality, intra-abdominal pressure （lAP）, Acute Physiology and Chronic Health Evaluation II （APACHE II） score, C-reactive protein （CRP）, oxygenation index, Balthazar CT score, rate of renal failure, decompression rate, intensive care unit （ICU） transfer rate, and length of hospital stay （LOS） were compared between the two groups. Results Compared to the control group, the modified DCQD treatment significantly decreased lAP （P 〈0.05） and APACHE II （P 〈0.05） scores on days 4-8, CRP on day 8 （P 〈0.01）, renal failure rate （P 〈0.05）, and LOS （P 〈0.05）. The oxygenation index was significantly improved in the DCQD group compared with the control group （P 〈0.05）. No significant differences in the Balthazar CT score, shock rate, ICU transfer rate, or mortality occurred between the two groups. Conclusions The modified DCQD can effectively relieve IAH and decrease LOS for patients with SAP. Larger clinical trials are needed to confirm these findings.

Results Although there were some differences between TD and MDNP in chemical ingredients, there was no significant difference in animal experiments and clinical trials（P 〉 0.05）. Conclusion The traditional and machinery decoctions of DCQD could be used bioequivalently.

On Ctteng Chung-Ying＇s Bentiyong Onto-hermeneutics

The onto-hermeneutic approach to bentiyong 本体用 championed by Cheng Chung-Ying 成忠英 is a valuable addition to comparative philosophy. In his well-honed reading, bentiyong is described as the continuous, integrative substance at the base of things, which becomes known through an ongoing hermeneutic integration and interpretation of reality. However, his use of the English word ＂substance＂ to describe bentiyong is problematic, mainly because substance, being without properties and existing without change, cannot be read as part of a hermeneutic process. Luckily, there are resources within the Chinese philosophical tradition that can help in overcoming some of the difficulties in translation presented here. Namely, the way that Zhu Xi 朱熹 approaches ti-yong as a principle （li 理） provides a better and more fittingly discursive basis for expressing the onto-hermeneutic character of bentiyong intended by Cheng, and allows English translation of the term with a firm footing in mainstream Neo-Confucianism.

Treatment of abdominal compartment syndrome in severe acute pancreatitis patients with traditional Chinese medicine

AIM: To investigate the therapeutic effect of traditional Chinese traditional medicines Da Cheng Qi Decoction (Timely-Purging and Yin-Preserving Decoction) and Glauber's salt combined with conservative measures on abdominal compartment syndrome (ACS) in severe acute pancreatitis (SAP) patients. METHODS: Eighty consecutive SAP patients, admitted for routine non-operative conservative treatment, were randomly divided into study group and control group (40 patients in each group). Patients in the study group received Da Cheng Qi Decoction enema for 2 h and external use of Glauber's salt, once a day for 7 d. Patients in the control group received normal saline (NS) enema. Routine non-operative conservative treatments included non-per os nutrition (NPON), gastrointestinal decompression, life support, total parenteral nutrition (TPN), continuous peripancreatic vascular pharmaceutical infusion and drug therapy. Intra-cystic pressure (ICP) of the two groups was measured during treatment. The effectiveness and outcomes of treatment were observed and APACHE Ⅱ scores were applied in analysis. RESULTS: On days 4 and 5 of treatment, the ICP was lower in the study group than in the control group(P < 0.05). On days 3-5 of treatment, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores for the study and control groups were significantly different (P < 0.05). Both the effectiveness and outcome of the treatment with Da Cheng Qi Decoction on abdominalgia, burbulence relief time, ascites quantity, cyst formation rate and hospitalization time were quite different between the two groups (P < 0.05). The mortality rate for the two groups had no significant difference. CONCLUSION: Da Cheng Qi Decoction enema and external use of Glauber's salt combined with routine non-operative conservative treatment can decrease the intra-abdominal pressure (IAP) of SAP patients and have preventive and therapeutic effects on abdominal compartment syndrome of SAP.

“起承转合”与“正反合”的比较

“起承转合”是中国传统的章法学术语,而“正反合”是德国古典哲学的概念。前者是文法形式,后者是思想形式。两者在具体的运用过程中,都试图不断地提高其普遍性的价值,但也都遭遇到不同的质疑和批判。对两者进行比较,进而发现其共同的问题,从而在理论思考方面有所推进,这是非常必要的。无论是“起承转合”还是“正反合”,都是人类特定认识阶段的思想总结的产物。它们作为一种“形式”的局限性本源于人类自身的局限性,也因此,我们讲论“形式”的时候,总是遭遇有限性的问题。与此同时,它们之间也并没有向对方过渡或转化的态势,这种现象耐人寻味。

程颐《春秋传》及其《春秋》诠释学

程颐乃《春秋》宋学之推助者,视《春秋》为“圣人之用”,以为学者只观《春秋》亦可尽道。其曾揭示治经之要领,如“《传》为案,《经》为断”“以传考经之事迹,以经别传之真伪”,凸显了《左传》解经之功能。晚年著《春秋传》,阐发正人伦、谨名分、尊周王、攘夷狄诸大义;且持天理、人道取代微辞隐义,进行创造性诠释。对于《春秋》或书或不书、或称或不称之笔削,与夺进退、褒贬劝惩之指义,抑纵、微显相反相成之笔法,事同则辞同、事同而辞异诸书法义例,观百物、聚众材与张本继末、系统宏观之比事属辞解经方法,程颐《春秋》学多有具体而微之提示。

英汉篇章修辞对比研究中的方法问题

对比修辞学领域内一个争议较大的问题是:英汉篇章修辞结构之间有没有本质差别?以Kaplan为代表的学者坚持汉语篇章受八股文或起-承-转-合结构的影响,是间接发展的,而其他研究者倾向于认为英汉篇章结构之间并无本质差别。本文通过对一些主要研究进行分析发现,许多研究存在方法上的缺陷,如过于依赖中国学生的英语作文,分析样本过小等,从而影响了结果的可信度。因此,作在建议未来的对比修辞研究应多注意方法上的问题。
