Objective: To investigate the mechanisms of moxibustion in the treatment of the colonic fibrosis in ulcerative colitis (UC) by observing the colonic fibroblast (CFB) synthesizing and secreting collagen in ulcerative colitis fibrosis rats. Methods: A rat model of ulcerative colitis fibrosis was established by immunological methods using human colonic mucosa as antigen adding local stimulation. The rats were randomly divided into normal group, model group, herb-partition moxibustion group, mild-warm moxibustion group and western medicine group (SASP group). Herb-partitioned moxibustion group and mild-warm moxibustion group treated by herb-partitioned moxibustion and mild-warm moxibustion respectively on Qihai (CV 6) and Tianshu (ST 25, bilateral) points. SASP group fed with salicylazosulfapyridine. Colonic fibroblasts from all the rats were isolated and cultured and the effects of moxibustion on the colonic fibroblast synthesizing and secreting type I, III, and IV collagen were observed. Results: The supernatant of cultured CFB from UC rats could stimulate the CFB of normal rats to secrete type I, III, and IV collagens. The supernatant from rats treated by herb-partitioned moxibustion and mild-warm moxibustion inhibited the secretion of type I , III, and IV collagens of CFB in normal rats. And the western medicine group also had some inhibiting effects on the type I and HI collagens. Conclusion: Moxibustion can regulate the functions of CFB synthesizing and secreting type I, III, and IV collagens in ulcerative colitis fibrosis rats.

Objective:To observe the impacts of herb-partitioned moxibustion,warm moxibustion and electroacupuncture on the basic fibroblast growth factor(bFGF)and collagen type Ⅰ(Col Ⅰ)in colons of rats with Crohn' disease(CD),and discuss the mechanism of acupuncture therapy on the intestinal fibrosis in CD.Methods:The model rats were developed by TNBS as multiple proinflammatory method.The rats were randomly divided into 5 groups:a normal group,a model group,a warm moxibustion group,an electroacupuncture group and a herb-partitioned moxibustion group.The treatments were carried out at Tianshu(ST 25)(bilateral)and Qihai(CV 6)in different treatments.The immunohistochemistry was used to detect the expression position of Col Ⅰ and bFGF.Results:The expressions of Col Ⅰ and bFGF in colons of rots in the model group significantly increased(compared with the normal group,P<0.01).After the herb-partitioned moxibustion,warm moxibustion and electroacupuncture,the expressions of Col Ⅰ and bFGF reduced markedly in the rats with CD(P<0.01).The expression of bFGF and Col Ⅰ in the colons had an obvious correlation in the Spearman rank correlation analysis.Conclusion:Acupuncture treatment reduced the abnormally high levels of expressions for Col Ⅰ and bFGF in colons.Col Ⅰ and bFGF participated in the fibrosis.Acupuncture treatment may reduce the bFGF expression in colons to regulate the excessive deposition,treating the intestinal fibrosis in CD.

Objective To investigate the pathologic morphology and immunohistochemical phenotypes of sarcomatoid carcinoma(SC) of the fallopian tube.Methods One case of SC of the fallopian tube was studied under the light microscopy for morphology.Immunohistochemistry was used to detect the expression of CK,EMA,S-100,Desmin,SMA,Leu-7,CD68,actin,and Vimentin in SC tissues.Pathologic features and biological behaviors of SC were analyzed in combination with the review of literature.Results Microscopically carcinomatous and sarcomatous elements co-existed.Usually the sarcomatous element formed the bulk of the lesion.In the sarcomatous tissues,there was no distinguishable bone,cartilage,rhadomyosarcoma,etc. Immunohistochemically the strong expression of CK7,EMA and Vimentin,and the partial expression of S-100,SMA,Leu7,CD68 and actin were detected.Conclusion SC of the fallopian tube is lack of specific symptoms,and its preoperative diagnosis is difficult.B-ultrasonography,CT and MRI are helpful to the staging of SC.Final diagnosis of SC depends on pathological examination and immunohistochemistry.SC is rare,and undergoes blood metastasis in early stage.Prognosis of SC is worst.Early detection of SC is the key to improve the prognosis.

Objective:To explore the prevalence of irritable bowel syndrome (IBS) based on a community population of Shanghai and the treatment of IBS by acupuncture therapy.Methods:A population of 1 685 subjects aged between 18-80 years were randomly selected by clustered sampling from the inhabitants in Changqiao Community of Shanghai to receive a questionnaire,for understanding the symptomatology and prevalence of IBS according to modified Manning and Rome II criteria,and the voluntary IBS patients were treated by acupuncture therapy.Results:The community- based prevalence of IBS was 11.45 % and 5.04% respectively according to modified Manning criteria and Rome II criteria.The ratio of male and female was 0.77:1 in IBS patients and the proportion was 10.62% and 12.19% respectively.But there were no significant difference in prevalence between different age groups (P＞0.05) .IBS is more common in subjects aged between 45-65 years (38.86%).Regarding the 62 IBS patients treated by electroacupuncture (EA),the total effective rate in Tianshu (ST 25) group (n=32) was 84.38%,and it was 56.67% in Daheng (SP 15) group (n=30),which showed a significant difference.(P＜0.05).Conclusion:IBS is a commonly encountered disorder in Changqiao Community of Shanghai and should be taken into consideration for human welfare,disease prevention and further epidemical investigation.Acupuncture treatment is recommended for treating IBS due to its satisfactory therapeutic effect.

BACKGROUND: Silibinin has broad pharmaceutical effects, such as anti-free radicals, anti-lipid peroxidation, anti-lipoid oxidase, anti-glutathione (GSH) depletion, anti-neoplastic and serum lipid-lowering effects. Clinically, silibinin is often used in treating alcoholic liver disease. OBJECTIVE: To investigate the pharmacological mechanism of silibinin for alcoholic fatty liver in rats. DESIGN: Randomized and controlled study.SETTING: Guangzhou Hospital of Traditional Chinese Medicine.MATERIALS: The experiment was conducted at the Animal Experimental Laboratory of Guangdong Pharmaceutical Institute from August to October 2003. Totally 57 SD rats, without unusual bacteria, weighting (150±10)g and of either gender, were selected. Yiganling tablets containing 38.5 mg silibinin were produced by Zhuzhou No.3 Pharmaceutical Factory (Batch No. 20020808).METHODS: Among the 57 SD rats, 18 rats were regarded as normal control group. Rats in normal control group were administered with normal saline by gavage, and fed with normal food and distilled water in place of alcohol for 10 weeks. Rats in model group and silibinin group were fed with high-calorie food and 100 mL/L alcohol for 6 weeks to establish model of rat alcoholic fatty liver. The other rats were divided into model control group (n=18) and silibinin group (n=21). Rats in model control group were treated with distilled water while those in silibinin group were treated with 100 mg/kg silibinin. Meanwhile, 100 mL/L ethanol and hyperalimentation feed were given for 4 weeks. After animals were killed, TG, SOD, GSH and MDA levels were measured with liver suspension.MAIN OUTCOME MEASURES: Contents of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP), total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), tumor necrosis factor (TNF)-α , and transforming growth factor (TGF)-β1.RESULTS: All the 57 rats entered the final analysis. Silibinin could inhibit the activities of serum AST, ALT and AKP [(2 550.5±400.1), (533.4±100.0), (2 217.1±750.2)nkat/L], and the differences were significant as compared with those in model control group [(3 600.7±666.8), (800.2±100.0), (2 900.6±1 333.6) nkat/L, P ＜ 0.05-0.01]. Contents of TG, LDL-C, TNF-α and TGF-β1 in silibinin group [(1.8±0.8), (0.17±0.04), (6.66±1.38), (24.1±4.1) mmol/L] were lower than those in model group [(2.8±1.4), (0.20±0.05), (7.81±1.06), (28.8±6.3) mmol/L] with significant differences (P ＜ 0.05-0.01). Silibinin could increase the content of HDL-C but decrease the contents of TG and MDA (P ＜ 0.05-0.01), and improve SOD activity as well as hepatocyte and fatty degeneration (P ＜ 0.01).However, it had no obvious effect on the content of reduced estathion (P ＞ 0.05).CONCLUSION: Silibinin can inhibitthe formation of alcoholic fatty liver in rats. The pharmacological mechanism of silibinin may involve anti-oxidation, removing free radicals, inhibiting lipid peroxidation, regulating blood lipid component, reducing fatty sediment in liver, and anti-immunoinflammation and anti-hyperplasia effects.

BACKGROUND:Chronic visceral pain is one of major complaints of irritable bowel syndrome which seriously affects patient’s quality of life. Recent researches have shown that moxibustion therapy has positive effects on aleviating chronic visceral pain in irritable bowel syndrome patients.
OBJECTIVE: To study the clinical utility of moxibustion in coping with chronic visceral pain of irritable bowel syndrome patients, and shed light on the theoretical basis of moxibustion analgesia, thereby to give insights into the further research and application on moxibustion.
METHODS: With the key words of “moxibustion, irritable bowel syndrome, visceral pain, abdominal pain” in Chinese and in English, respectively, a computer-based search was performed in CNKI, VIP, Wanfang and PubMed databases for articles published from January 1990 to October 2014. After the initial screening, the remained articles went through further selection and categorization.
RESULTS AND CONCLUSION:The result shows promising results of moxibustion on relieving chronic visceral pain for both two subtypes of irritable bowel syndrome patients, diarrhea type and constipation type. Moxibustion may exert an analgesic effect on chronic visceral pain in irritable bowel syndrome patients through regulation of visceral hypersensitivity, gastrointestinal motility disorders, brain-gut axis and neuroendocrine system disorders, immune dysfunction and low-grade inflammation in the gut, psychological abnormalities, and alteration of intestinal flora. However, to fuly understand the analgesia effect of moxibustion and elucidate its mechanism, more standardized randomized controled trials employing advanced scientific techniques and equipments wil stil be needed in the future.
