OBJECTIVE@#To explore the possible effects and mechanism of Zhizhu Decoction (ZZD) on the pathophysiology of slow transit constipation (STC).@*METHODS@#A total of 54 C57BL/6 mice was randomly divided into the following 6 groups by a random number table, including control, STC model (model), positive control, and low-, medium- and high-doses ZZD treatment groups (5, 10, 20 g/kg, namely L, M-, and H-ZZD, respectively), 9 mice in each group. Following 2-week treatment, intestinal transport rate (ITR) and fecal water content were determined, and blood and colon tissue samples were collected. Hematoxylin-eosin and periodic acid-Schiff staining were performed to evaluate the morphology of colon tissues and calculate the number of goblet cells. To determine intestinal permeability, serum levels of lipopolysaccharide (LPS), low-density lipoprotein (LDL) and mannose were measured using enzyme-linked immunosorbent assay (ELISA). Western blot analysis was carried out to detect the expression levels of intestinal tight junction proteins zona-occludens-1 (ZO-1), claudin-1, occludin and recombinant mucin 2 (MUC2). The mRNA expression levels of inflammatory cytokines including tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-4, IL-10 and IL-22 were determined using reverse transcription-quantitative reverse transcription reaction. Colon indexes of oxidative stress were measured by ELISA, and protein expression levels of colon silent information regulator 1/forkhead box O transcription factor 1 (SIRT1/FoxO1) antioxidant signaling pathway were detected by Western blot.@*RESULTS@#Compared with the model group, ITR and fecal moisture were significantly enhanced in STC mice in the M-ZZD and H-ZZD groups (P<0.01). Additionally, ZZD treatment notably increased the thickness of mucosal and muscular tissue, elevated the number of goblet cells in the colon of STC mice, reduced the secretion levels of LPS, LDL and mannose, and upregulated ZO-1, claudin-1, occludin and MUC2 expressions in the colon in a dose-dependent manner, compared with the model group (P<0.05 or P<0.01). In addition, ZZD significantly attenuated intestinal inflammation and oxidative stress and activated the SIRT1/FoxO1 signaling pathway (P<0.05 or P<0.01).@*CONCLUSION@#ZZD exhibited beneficial effects on the intestinal system of STC mice and alleviated intestinal inflammation and oxidative stress via activating SIRT1/FoxO1 antioxidant signaling pathway in the colon.

Objective::To observe effect of addition and subtraction therapy of Huaihuasan combined with Taohuatang to ulcerative colitis with cold-heat complicated syndrome at active stage, and to study regulation effect to immune function and inflammatory response. Method::One hundred and twelve patients were randomly divided into control group and observation group by random number table. Patients with light and middle symptoms in control group got mesalazine slow release tablets, 1.0 g/time, 3 times/days, patients with severe symptoms or whose symptoms were not changed after getting for 4 weeks in control group got prednisone acetate tablets, 0.75 mg·kg-1·d-1 for 3 times. Based on the treatment in control group, patients in observation group added Huaihuasan combined with Taohuatang, 1 dose/day. The course of treatment was 4 weeks. At remission period, mesalazine slow release tablets were used for maintain long-term maintenance therapy, 0.5 g/times, 3 times/days. Scores of disease activities were graded by improvement mayo, and clinical remission and clinical efficacy were recorded, scores of cold-heat complicated syndrome, mucous membrane under enteroscopy and histology of mucosa belongs to Geboes were graded. And levels of tumor necrosis factor-α(TNF-α) in peripheral blood, interleukin-8 (IL-8), IL-10, T lymphocyte subsets (CD4+, CD8+), and adverse reactions, 6 months' follow-up and recurrence were also be recorded. Result::Therapeutic effect of traditional Chinese medicine syndromes were analyzed by rank sum test, which in observation group was better than that in control group (Z=1.915, P<0.05). Clinical effect in observation group was 98.04%(50/51) higher than 84.00%(42/50) in control group, clinical remission rate was 94.12%(48/51) higher than 78.00%(39/50) in control group, and mucosal healing rate was 96.08%(49/51) higher than 82.00%(41/50) in control group (P<0.05). Scores of mayo, cold-heat complicated syndrome, colonic mucosa and index scores of Geboes were all lower than those in control group (P<0.01). And levels of TNF-α, IL-8 and CD8+ were lower than those in control group (P<0.01), and levels of IL-10, CD4+ and CD4+ /CD8+ were higher than those in control group (P<0.01). Recurrence rate during 6 months in observation group was 10.42%(5/48) lower than 30.77%(12/39) in control group (χ2=5.669, P<0.05), as for adverse reactions, there was no significant difference between two groups. Conclusion::Huaihuasan combined with Taohuatang can induce UC to remission period, inhibit the activity of disease, alleviate clinical symptoms, regulate immune function and expression of inflammatory factors, alleviate inflammatory reaction, promote intestinal mucosal healing, and can maintain clinical remission and reduce recurrence. The clinical efficacy is superior to that of 5-ASA/glucocorticoid in Western medicine.

Objective:To observe clinical efficacy of Taohua Tang and Buzhong Yiqi Tang on Crohn's disease (CD) at active phase (deficiency-cold in spleen and stomach), in order to observed its effect on Th1 and Th17 cytokines. Method:According to random number table, 86 patients with CD were divided into control group (42 cases) and observation group (44 cases). The control group (mild) was given SASP, 3-4 g·d-1, Po, tid. The control group (moderate or poor efficacy of SASP) was given prednisone acetate, 0.75 mg·kg-1·d-1, Po, tid. Observation group was given Taohua Tang and Buzhong Yiqi Tang in addition to therapy of the control group, 1 dose·d-1. The course of treatment was 12 weeks. Before and after treatment, Best CDAI, SES-CD, IBDQ and deficiency syndrome were scored, and levels of CRP, ESR, ALB, HB, PLT, IFN-γ, TNF-α, IL-2 and IL-17 were measured before and after treatment. Result:After treatment, the effect of traditional Chinese medicine(TCM) syndromes in the observation group was better than that in the control group (Z=2.058, PPPPZ=2.112, PZ=2.288, PPPγ, TNF-α, IL-2 and IL-17 levels in the observation group were lower than those in the control group (PConclusion:In addition to the therapy of conventional western medicine, Taohua Tang and Buzhong Yiqi Tang in treatment of deficiency syndrome of Crohn's disease (CD) can control the activity degree of the disease, reduce the degree of illness and inflammation, and improve the remission rate and the quality of life, with a better clinical efficacy than the pure western medicine therapy.
