ABSTRACT
Background: Anal fissure is one of the most common anal-rectum diseases, and approximately 10 percent patients with chronic anal fissure ultimately receive surgery. Relieving postoperative pain and protecting functions of the sphincter are central issues for coloproctologists. Objective: To evaluate the efficacy and safety of anoplasty in the treatment of chronic anal fissures. Design, setting, participants and interventions: In this prospective, multicenter, randomized controlled trial, 120 adult patients with chronic anal fissure were referred from Department of Coloproctology of Yueyang Hospital of Integrated Traditional Chinese Medicine Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and Shanghai Municipal Hospital of Traditional Chinese Medicine. The patients were enrolled from January 2009 to April 2010 and randomly divided into study (mucosa advancement flap anoplasty, abbreviated as anoplasty) group and control (fissurectomy) group. The two groups were assessed separately, and the main outcome measures were observed for 2 weeks, with a short-term follow-up for 6 weeks. Main outcome measures: Degree of pain, haemorrhage and anal canal pressure were observed and recorded preoperatively, and on the third day, the fourteenth day and the sixth week postoperatively. The wound healing time was also recorded. Surgical complications of the two groups were recorded and compared on the third day and the sixth week postoperatively. The curative effects associated with the surgery were analyzed on the fourteenth day and the sixth week after surgery and the therapeutic results were evaluated. Results: Three patients were dropped out due to the early discharge from hospital and losing connection (1 in study group and 2 in control group). Overall the surgery showed that the anoplasty group had better results than the fissurectomy group in the curative effect on the sixth week after operation (P0.05). There were no significant differences in relieving the anal canal pressure (P>0.05) and the surgical complications (dysuria, edema of anal margin, fever, infection, anal incontinence and anal deformation) between the two groups (P>0.05). None of the patients suffered postoperative complications by the sixth week after operation. Furthermore, there was no recurrence in either of the two groups at six weeks after operation. Conclusion: The results indicate that anoplasty for chronic anal fissures has advantages such as better therapeutic effects, less postoperative pain, a shorter healing time and no incidence of anal incontinence.
ABSTRACT
OBJECTIVE: To compare the influence of traditional Chinese compound recipes (TCCRs) with different efficacy on body weight, tumor weight and immune function in H22 cancer-bearing mice. METHODS: H(22) cancer-bearing mice were chosen to observe the effects of TCCRs with different efficacy on tumor growth inhibition and detect the proliferation function of T lymphocytes, the activity of natural killer (NK) cells, the changes of T lymphocytes and the content of interferon-gamma (IFN-gamma)and interleukin-4 (IL-4). RESULTS: Tumor weight of H(22) cancer-bearing mice in Yidu Gongdu Recipe (YDGDR, a compound traditional Chinese herbal medicine using poison as an antidote for poison)-treated group was obviously lighter than that in the other TCCR-treated groups and the tumor inhibition rate in YDGDR-treated group was 65.76% (P<0.01). The tumor inhibition rates in other TCCR-treated groups were ranged from 10.1% to 17.1% . Body weight of mice in YDGDR-treated group was obviously decreased and depilation was observed at the same time. Pelage of mice in Fuzheng Peiben Recipe (FZPBR, a compound traditional Chinese herbal medicine for supporting the healthy energy)-treated group grew well, and behavior of the mice was active. Stimulation index (SI) of T lymphocyte transformation in YDGDR-treated group was obviously increased (SI=4.34, P<0.01), which showed the proliferation function of T lymphocyte was very strong. The SI of T lymphocyte transformation in the other groups was less than three, which showed the proliferation function of T lymphocytes was not significant. Compared with normal saline (NS)-treated group, percentages of NK cells in Qinre Jiedu Recipe (QRJDR, a compound traditional Chinese herbal medicine for clearing away heat and toxic substances)-treated, Huxue Huayu Recipe (HXHYR, a compound traditional Chinese herbal medicine for activating blood circulation to dissipate blood stasis)-treated and YDGDR-treated groups were obviously increased and 5.05, 4.07 and 5.17 times more than the NS-treated group, respectively (P<0.01). The activity of NK cells wasn't increased in the FZPBR-treated and HXHYR-treated groups. The production of IFN-gamma induced by T cells in YDGDR-treated group was obviously raised (P<0.05), and the production of IL-4 induced by T cells in QRJDR-treated, HXHYR-treated, Huatan Sanjie Recipe (a compound traditional Chinese herbal medicine for eliminating phlegm and resolving masses)-treated and YDGDR-treated groups was also raised obviously (P<0.01). CONCLUSION: YDGDR has a good effect of inhibiting tumor growth and can reinforce cellular and humoral immune function in tumor-bearing mice. FZPBR can strengthen the body.
ABSTRACT
OBJECTIVE: To investigate the mechanisms of tumor inhibiting and immunoloregulation of Mylabris Mixture on H22 cancer-bearing mice. METHODS: H22 cancer-bearing mice were chosen to observe the effects of tumor inhibiting and detect the proliferation function of T lymphocytes, the toxicity function of NK cells, the changes of T lymphocytes and the contents of interferon-gamma and interleukin-4. RESULTS: Mylabris Mixture could obviously inhibit the growth of H22 cancer in mice, and the tumor inhibition rat was 65.76%. The stimulation index of T lymphocyte transformation and percentage of NK cells in Mylabris Mixture-treated group were obviously higher than those in the normal control group. The subpopulation proportion of T lymphocytes in Mylabris Mixture-treated group was changed more than the normal control group. The production of interferon-gamma and interleukin-4 by T lymphocytes obviously increased in Mylabris Mixture-treated group (P<0.05, P<0.001). CONCLUSION: Mylabris Mixture has the effect of inhibiting the growth of tumor constitution, and regulating immunological function on mice with tumor. Its mechanisms include the reinforcement of T lymphocyte immune function, NK cell killing function and humoral immune function.
