Therapeutic Efficacies of Wujiwan at Different Compatibilities in Treatment of Irritable Bowel Syndrome / 中国实验方剂学杂志

Objective:To compare the therapeutic efficacies of Wujiwan at two different compatibilities （No.1 and No.2） on irritable bowel syndrome （IBS） based on neuro-endocrine-immune network， and provide a theoretical basis for the treatment based on syndrome differentiation in traditional Chinese medicine （TCM）. Method:The chronic animal model of IBS with visceral hypersensitivity was established by colon irritation via percutaneous transluminal coronary angioplasty （PTCA） in suckling rats. The animals were randomly divided into a control group， a model group， a dicetel group （0.01 g·kg^-1）， low- （0.335 g·kg^-<bold>¹</bold>）， medium- （0.67 g·kg^-<bold>¹</bold>）， and high-dose （1.34 g·kg^-<bold>¹</bold>） No. 1 Wujiwan groups， and low- （0.385 g·kg^-<bold>¹</bold>）， medium- （0.77 g·kg^-<bold>¹</bold>）， and high-dose （1.54 g·kg^-<bold>¹</bold>） No. 2 Wujiwan groups. The thresholds of abdominal elevation and bow back elevation were evaluated to detect the effect of Wujiwan on intestinal sensitivity of IBS. The density of mast cells （MC） in the colonic tissue of model rats was detected by the modified toluidine blue staining method. The concentrations/positive expression of 5-hydroxytryptamine （5-HT）， substance P （SP）， somatostatin （SS）， and vasoactive intestinal peptide （VIP） in the blood/colon tissue were detected by enzyme-linked immunosorbent assay （ELISA） and immunohistochemistry （IHC） assay. Result:There was no significant difference in body weight among different groups. Compared with the control group， the model group exhibited decreased thresholds of abdominal elevation and bow back elevation （<italic>P<</italic>0.01）， increased density of MCs in the colon tissue （<italic>P<</italic>0.05）， up-regulated levels of 5-HT， SP， and SS in the blood and colon tissue （<italic>P<</italic>0.05， <italic>P<</italic>0.01）， and elevated VIP level in the colon tissue （<italic>P</italic><0.05）. Compared with the model group， Wujiwan at different compatibilities could increase the thresholds of abdominal elevation and bow back elevation （<italic>P</italic><0.01）， diminish the count of MC in the colon tissue （<italic>P</italic><0.05）， and reduce the levels of 5-HT， SP， SS， and VIP （<italic>P</italic><0.05）. As demonstrated by the comparison of No. 1 and No. 2 Wujiwan， No. 1 was superior to No. 2 in reducing the concentrations of 5-HT， SP， and SS in the blood， especially in 5-HT （<italic>P</italic><0.01）. No significant difference between No. 1 and No. 2 in reducing 5-HT positive expression in the colon tissue was observed. Compared to the No. 1 Wujiwan， No. 2 significantly reduced SP expression， and the intensity and range of SS expression in the colon tissue in the No. 2 groups were smaller than those in the No. 1 groups （<italic>P</italic><0.05）. Conclusion:Wujiwan at different compatibilities was capable of improving gastrointestinal hormone disorder of IBS to reduce intestinal sensitivity. In terms of systemic effect， No. 1 was superior to No. 2， while in terms of local effect， No. 2 was advantageous. No. 1 Wujiwan was superior to No. 2 in the effect on intestinal dynamics， while No. 2 had an advantageous effect on intestinal sensation over No. 1.

Clinical Efficacy of Modified Heweitang in Treatment of Functional Dyspepsia Due to Liver-stomach Disharmony / 中国实验方剂学杂志

Objective:To explore the clinical efficacy and safety of modified Heweitang in the treatment of functional dyspepsia （FD） due to liver-stomach disharmony and its regulation of gastrointestinal hormones and brain-gut peptides. Method:One hundred and twenty-six eligible patients were randomized into a control group （62 cases） and an observation group （64 cases）. Patients in the observation group took the modified Heweitang granules with warm water 30 min after meals， 10 g/time， 3 times/day， while those in the control group took the corresponding placebo granules at the same dose in the same manner. The treatment in both groups lasted for four weeks. Before and after treatment， the four main symptoms including postprandial satiety， early satiety， upper abdominal pain， and upper abdominal burning sensation were scored， followed by the examination of gastric emptying （GE） and the scoring of the functional digestive disorders quality of life questionnaire （FDDQL）， 7-point global overall symptom scale （GOSS）， and liver-stomach disharmony syndrome. The cholecystokinin （CCK）， motilin （MTL）， gastrin （GAS）， serotonin （5-HT）， vasoactive intestinal peptide （VIP）， and substance P （SP） levels before and after treatment were detected， and then the safety was evaluated. Result:After treatment， the scores of the four main symptoms， GOSS， and liver-stomach disharmony syndrome in the observation group were lower than those in the control group （<italic>P</italic><0.01）， while the GE rate and FDDQL scores in the observation group were higher （<italic>P</italic><0.01）. The CCK， GAS， 5-HT， and VIP levels of the observation group declined as compared with those of the control group （<italic>P</italic><0.01）， whereas the MTL and SP levels were elevated （<italic>P</italic><0.01）. After treatment， the overall response rate in the observation group was （51/57）89.47%， higher than （15/56）26.79% in the control group （<italic>χ</italic>²=45.696， <italic>P</italic><0.01）. No drug-related adverse reactions were found during the trial. Conclusion:The modified Heweitang is efficient and safe in relieving the main and related symptoms and traditional Chinese medicine （TCM） syndrome， regulating the secretion of gastrointestinal hormones and brain-gut peptides， promoting GE rate， and improving the quality of life of patients with FD due to liver-stomach disharmony.

Regulatory effect of a Chinese medicine Wuji Pill ( WJW) on brain-gut peptides in the rats of post-inflammatory irritable bowel syndrome / 中国实验动物学报

Objective To explore the biological indicators of diagnosis and treatment of irritable bowel syndrome (IBS), and to explore the mechanism of action of a Chinese medicine Wuji Pill (WJW) on irritable bowel syndrome (IBS). Methods (1) Postinflammatory irritable bowel syndrome (PI-IBS) rat model was established by acetic acid plus restraint stress method . (2) The colonic motor ability of rats was evaluated by colon motility index (MI), the number of fecal particles discharged within 2 h, and the time of glass pellet discharge. (3) The formation of PI-IBS model rats and the therapeutic effect of WJW were observed. (4) The levels of calcitonin gene-related peptide (CGRP), motilin (MTL), neuropeptide Y (NPY), substance P (SP), somatostatin (SS), vasoactive intestinal peptide (VIP), and cholecystokinin (CCK) in the brain and colon tissues of PI-IBS rats were measured by ELISA. Results (1) The rat PI-IBS model was successfully established. Compared with the normal group, the body weight of the model rats was decreased, the food intake decreased, the amount of feces increased, loose stools and amorphous soft stools appeared, voluntary movements decreased, colon motility index ( MI) significantly increased ( P ＜ 0. 05 ), the number of fecal particles discharged significantly increased ( P＜ 0. 05), and the glass pellet discharge time was significantly shortened ( P ＜ 0. 05). (2) WJW treatment for 7 days significantly improved a variety of symptoms. Compared with the normal control, the levels of CGRP, SS and VIP in the brain tissue of PI-IBS rats were significantly increased (P＜ 0. 05), and the NPY concentration was significantly decreased ( P ＜ 0. 05). However, the treatment with WJW significantly reduced CGRP, SS and VIP levels (P＜ 0. 05), and significantly increased the NPY concentration level (P ＜ 0. 05). (3) Compared with the normal control group, the levels of CCK, NPY, MTL, SS and VIP in colonic tissues of PI-IBS rats were significantly decreased (P＜ 0. 05), while WJW significantly increased the CCK and VIP levels. Conclusions WJW can be used to treat IBS by regulating the levels of various brain-gut peptides in the brain and colon tissues of IBS rats. These anomalous and adjustable brain-gut peptides may become a potential biomarker for the diagnosis and treatment of IBS.

Neural Mechanisms of Acupuncture for Functional Dyspepsia / 世界科学技术-中医药现代化

Acupuncture, as one of the most distinctive traditional Chinese medicine (TCM) treatment, had a wide range of advantages in the treatment of gastrointestinal disorders with obvious clinical efficacy. The onset of functional dyspepsia had increased year by year. However, the exploration on mechanism was unclear and drug abuse showed poor clinical outcomes. Acupuncture can effectively improve gastric motility. Through a variety of ways to act on the gastrointestinal tract, gastrointestinal function was restored to improve a variety of symptoms in patients with functional dyspepsia, which provided scientific basis for the clinical selection and application of acupuncture in functional dyspepsia treatment. This paper summarized the acupuncture treatment mechanism of functional dyspepsia in recent ten years, in order to provide references for scientific basis in acupuncture treatment of functional dyspepsia. It also provided references for the development of reasonable treatment options in the clinical practice.
