AIM To treat esophageal stricture secondary to the ingestion of corrosive materials in children using theileocolon with ileocecal valve as a substitute for esophagus.METHODS Between 1992 and 1999, isoperistaltic retrosternal ileocolic esophageal replacements wereperformed in 12 patients; 50 cadavers were studied to observe the vascularity in the ileocolic region andmetabolic indexes were measured before and after surgery or between the operative group and the normalcontrols in 20 piglet models.RESULTS A follow-up of 3 years in the 12 cases found no death in intra- and post- operative periodclinically. Cervical ileoesophageal anastomotic leaks occurred in 2 cases. The distribution pattern of venousvessel in the ileocolic region was far more constant than that of the artery. The arrangements of artery in theileocolic segment were classified into 7 types, and there was no interruption of paracolic anastomosis betweenarteries. The resections of 50 cm terminal ileum, cecum and 50 cm ascending colon affected enterohepaticcirculation of bile acid (bile salt) and the fatty metabolism in early period after surgery in piglet models.Shortening of the time and reducing of the area for water absorption after ileocolic resection resulted indiarrhea in piglet models. The loss of “bacterial barrier” role of ileocecal valve led to bacteria immigrationfrom colon to ileum and small intestinal bacterial overgrowth.CONCLUSION The ileocolic esophageal replacement taking advantage of antireflux role of the ileocecalvalve has obtained satisfactory effect. To understand the characteristics of the patterns of arteries and veinsdistribution and physiological functions of the ileocolic segment is useful in guiding clinical practice andpostoperative management and preventing postoperative complications as well.

AIM We have discovered that Limonene modulates interdigestive myoelectrical complexes (IMCs) ofgastrointestinal tract in rats. In this research we will elucidate weather limonene affects acetylcholine M-receptor in caudate nucleus.METHODS Changes of IMCs were studied after limonene and/or atropine were microinjected into caudatenucleus. IMCs were recorded by a RM-6200 four-channel recorder and then delivered to Maclab and PowerMacintosh.RESULTS The active phases of IMCs occupied about 40% of total cycle in average. After microinjection oflimonene into caudate nucleus, the active phases were significantly shortened, while the cycle time of IMCswere not changed significantly. The inhibitory effects of limonene were abolished by pretreatment withatropine, whilst the atropine has no effect on IMCs.CONCLUSION It is suggested that limonene inhabits the gastrointestinal IMCs by affecting M-receptor incaudate nucleus.

AIM To search for a new surgical method which accords with physiologico-anatomical principles, reducethe incidence rate of some postoperative complications in conventional Billroth I (CB1) gastrectomy andraise the life quality of patients after surgery.METHODS Using the blood vessels and innervation of the remaining stomach and duodenum, we designeda new pyloric sphincter reconstruction (PSR) in Billroth I gastrectomy, in which the end of the duodenumremnant is surrounded by the seromuscular valve of 2 cm wide in the end of the greater curvature, thickenedthe muscle of the stoma and reconstructed a similar pylorus with the sphincteric function.RESULTS Eleven patients were treated, 8 males and 3 females, 6 malignant and 5 benign and 1accompanied by mould infection, aged from 33 to 73 years, with 1 to 29 years of gastric disease history(average 7.9 years). The function of gastric emptying was shown to be essentially normal by barium mealstudy with video record one month after the operation. The pyloric-like control effect was present in thereconstructive pylorus. PSR vs CB1 vs NES (P >0.01); PSR vs CB1 (P < 0.01); PSR vs NSE (P >0.05).CONCLUSION The new method of pyloric reconstruction is safer, simpler and more effective thanconventional procedures. This method can be applied to all patients for whom Billroth 1 anastomosis can beperformed regardless of benign or malignant lesion.

AIM The hepatic content of collagens (type I, Ⅲ and Ⅶ) and laminin (LN) in rat model of experimentalliver fibrosis was observed to find out their roles in the pathogenesis of liver fibrosis.METHODS The experimental rat model was established by immunological injury induced by injectinghuman albumin. Histopathological and immunohistochemical methods were used to measure the hepaticcontent of collagens and laminin in the fibrotic rat livers.RESULTS The hepatic contents of collagens (type I, Ⅲ, Ⅶ) and LN in the fibrotic rat livers weresignificantly increased as compared with those in the control group, and they were found to be mainlylocalized in the portal space, central veins and fibrous septa. Electron microscopic study showed that pro-collagens were present around the “activated” hepatic stellate cells (HSC) and the hepatocytes atrophied.CONCLUSION Pathological deposition of collagens (type Ⅰ, Ⅲ and Ⅶ ) and laminin was the fundamentallesion of liver fibrosis. HSC may be the major cellular source of collagens (type Ⅰ, Ⅲ and Ⅶ) and laminin inthe liver tissue.

AIM To review the progress in pharmacological mechanisms of terandrine (Tet) and its therapeutic use indigestive diseases.METHODS We reviewed almost all the papers related to Tet from various magazines published in Englishand Chinese in recent years.RESULTS It has been demonstrated that Tet had multiple bioactivities: ① Tet could act as a Ca2+antagonist via blocking cellular plasma membrane voltage- or receptor-operating Ca2+ channels, inhibiting extracellular Ca2+ entry into the cell and intracellular Ca2+ mobilization to the cytosol, so as to preventhepatocytes, cardiomyocytes, pancreas cells and neurocytes from toxic or ischemia-reperfusion injuries.However, in HL-60 and leukemic T cells, Tet promoted Ca2+ releasing from mitochondria and microsomes,increased the concentration of intracellular Ca2 + , and induced cell death; ② Tet inhibited phobol 12-myristat13-acetate (PMA) plus ionomycin-induced T cell proliferation, interleukin-2 secretion and expression of theT cell activation antigen, CD71. It could also interrupt the integrity of macrophages, and reduced respiratoryburst of neutrophils and macrophages and proinflammatory cytokines secretion through minimizing nucleartranscriptional factor kappa B DNA binding activity; ③ Tet could induce tumor cell apoptosis, and down-regulate P-glucoprotein activity; and ④ Tet has the therapeutic effects on hepatic fibrogenesis, portalhypertension, immunomodulation, etc.CONCLUSION Tet can act as a Ca2 + channel blocker, inhibit proinflammatory factors releasing, modulateimmunoreaction, and induce tumor cell apoptosis. It can be used to prevent hepatocyte injury induced bytoxins and virus, inhibit hepatic fibrogenesis, reduce portal venous pressure, and can be used as an anti-tumor drug as well.

AIM We introduce a new highly selective vagotomy (HSV) procedure which can completely destroy anyexisting variant vagal fibers innervating the proximal stomach.METHODS Twenty-eight dogs were divided into three groups: group A had retrograde liberated highlyselective vagotomy (RLHSV), group B had traditional HSV and group C as control group. Gastric acidsecretion function was tested and gastric parasympathetic and sympathetic enervation were studied byretrograde tracing the horseradish peroxidase (HRP) or by histochemical staining. After being convincedthat the modified procedure was an easier and more effective HSV on animal model, we applied thetechnique to the treatment of duodenal ulcers in 100 patients.RESULTS Significant decrease of acid secretion was found in operated dogs in both group A and B. After injection of HRP subserously into the fundus and body, no HRP positive cells were found in the vagal dorsalnucleus in group A and B but were in group C. When HRP was injected into the antrum, HRP stained cellswere found in dorsal nucleus in all three groups. The negative histochemical staining of AchE and the positivefluorescence in the fundus and body in group A and B indicate that parasympathetic nerve fibers weredestroyed completely while norepinephrinergic nerve fibers were intact. When the operation was applied topatients, no severe complications or operative mortality occurred. Patients were followed up for 6- 84months. They all had complete gastric emptying function. Ninety-four patients were graded as Visick I orⅡ. Six as Visick Ⅲ and Ⅳ. Eighty patients had been followed up with gastroscopy for two years afteroperation. Four patients had recurrent ulcers. Among them two patients were asymptomatic and the othertwo had symptoms and were treated with partial gastrectomy.CONCLUSION Compared to the classic HSV, our modified procedure is more effective clinically andconvenient technically.

AIM To provide evidence that UBT is the most cost-effective tool for evaluation of H. pylori eradication.METHODS Data on twenty-six consecutive patients at Atlanta VA Hospital who underwent UBT wereretrospectively reviewed. All patients had endoscopic diagnosis of peptic ulcers and biopsy proven H. pyloriinfection. Eight to ten weeks after completion of triple therapy (amoxicillin, biaxin and prilosec), allpatients had C14 UBT (PY test kit, Charlottesville, Virginia). Ten patients had repeated endoscopicexaminations and gastric biopsies. Twelve patients had serology tests for H. pylori.RESULTS UBT was negative in all patients (two patients had indeterminate result on the first time, butshown to be negative on the second UBT). Biopsies from all ten patients who were re-endoscoped werenegative for H. pylori. Serology tests on all the twelve patients were positive. Cure of H. Pylori could notbe determined on the titer change. All patients spent about 30 minutes in nuclear medicine laboratory, theendoscopic patients spent 2 hours to 4 hours in endoscopic laboratory; the cost for a UBT was about 50, thecost for an endoscopy with biopsy was above 200.CONCLUSION The 04 UBT is a rapid, economic and accurate test to monitor H. pylori eradication. Thetest should be considered a gold standard test for evaluating the effectiveness of treatment of H. pyloriinfection, unless patients need repeated endoscopy to rule out gastric cancer.

Management of inflammatory bowel disease includes not only drug, endoscopic and surgical therapy but alsopsychosocial support, dietary and specific nutritional measures: a multidisciplinary medical, surgical, nursingand dietetic approach is essential for all patients, particularly those with complex or refractory disease. Inthis paper, current treatment of acute severe ulcerative colitis and steroid-refractory or -dependent Crohn'sdisease is reviewed. Adjunctive intravenous cyclosporin is an alternative to urgent colectomy in steroid-refractory patients with acute severe ulcerative colitis, while the place of intravenous heparin for thisindication awaits clarification. Azathioprine or 6-mercaptopurine are useful options in chronically active,steroid-refractory or -dependent Crohn's disease, but may take up to 4 months to work. Methotrexate is amore recent immunomodulatory alternative. Of new therapies selectively aimed at specific pathophysiologicaltargets, the first to reach clinical application is anti-TNF-alpha antibody (infliximab) for refractory Crohn'sdisease: its benefits are promising, but experience with it is limited to date, its cost is high and there areuncertainties about long-term safety. In view of the increasing variety and complexity of management optionsin inflammatory bowel disease, whether apparently responsive or difficult to treat, patients must participatein decisions about which therapies they are to be given.

AIM To examine hepatitis C in hepatocellular carcinoma in most endemic area, Guangxi, China.METHODS Immunochemistry was performed on formalin fixed, paraffin embedded tissue sections. A total202 specimens were analysed from the high, intermediate and low HCC prevalent regions of Guangxi.RESULTS The distribution of positive hepatitis C cases from high, intermediate and low regions wasrespectively 24/63 (38%), 23/62 (37%) and 30/77 (39%), with a total of 77/202 (38.12%).CONCLUSION Hepatitis C virus is an important risk factor in the development of hepatocellularcarcinoma, but the regional difference in prevalence of this cancer is more likely influenced by hepatitis Bviral infection and aflatoxin B1 exposure. In Guangxi, infection of hepatitis B and C virus in thedevelopment of hepatocellular carcinoma may be greatly enhanced by exposure to aflatoxin.

AIM To analyze the psychological characteristics of enterostomized patients, identify the effective methodsin order to improve the psychological rehabilitation of these patients and promote their quality of life.METHODS Questionnaires were filled up by 293 enterostomized patients pre- and post-operatively toidentify their psychological characteristics. One group (n = 45) of post-enterostomized patients were taughtto take care of stoma by irrigation, the others (n = 248) to merely look after the colostomy bag.RESULTS The psychological characteristics were identified as disbelief, fear, desperation or anxiety pre-operatively; as unstable mood, irritable, afraid, sense of lost body image or depression post-operatively; aslow self-esteem, self isolation, or despondent in rehabilitative period respectively. Results revealed that thepatients need psychological support both pre-operatively and post-operatively. Meanwhile, proper stoma careis of the same importance. After irrigation 1 -3 months regularly, most of the 45 regular irrigating patientswere free from skin irritation problems; 40(89%) patients had daily or bidaily motions; and most of themshowed an absence of fecal leakage or gases, and they hardly suffer from bad odors. Some of them even onlypartially use the colostomy bag. These patients were more confident to reinstate to their previous daily life.Only 5 (11%) patients had irregular bowel movements. Enterostomized patient club and out-patientconsultation clinic are beneficial to improve their psychological rehabilitation.CONCLUSION Careful pre-operative psychological support can help patient's post-operative adoption. Thepsychological rehabilitation of the patients can speed their physical recovery. Proper stoma care and earlyreinstatement into previous social life are also important to improve the patients' rehabilitation.

AIM To evaluate the clinical value of creatine kinase macroisoenzyme type 2 (CK-M2) and oligosaccharideprotein (OP) in serum from patients with gastric carcinoma (GC).METHODS Serum level of CK-M2 was detected by agar gel electrophoresis. OP concentration was measuredby an enzyme immunoassay.RESULTS Serum levels of CK-M2 and OP in 57 cases of GC were significantly higher than those in 51 caseswith gastric precancerous lesion and 28 controls. The diagnostic sensitivity and specificity for GC with CK-M2 was 56.10% and 98.63% respectively. CK-M2 and OP were not associated with histologic type and degreeof differentiation.CONCLUSION These results suggest that CK-M2 may serve as a marker to diagnose GC, and the specificityis higher, whereas OP is not more significant for GC diagnosis, but it could be a useful indicator forevaluation the status of body immune.

AIM To observe the effect of herbs-partition moxibustion on IL-1β and TNF-c in UC rats.METHODS The animal models were created by immunological method. They were divided into 5 groups atrandom, after treated by different methods, IL-1β and TNF-α in colon tissue of UC rats were detected withimmunologic technique.RESULTS In control group, there was a little or no IL-1β positive cell in colon mucosa. Compared withthat in rats of control group, the number of IL-1 positive cell in model group was much larger, and IL-1βcells with brown granules were mainly expressed in cytoplasm of macrophage in lamina propria of colon.Compared with model group, IL-1β positive cells in mild moxibustion group markedly decreased (P < 0.05),and those in electro-acupuncture group and herbs-partition moxibustion group decreased even more markedly(P < 0.01). The difference between the last two groups is evident (P < 0.05). TNF-α positive cells are not or seldomly found in UC rats, but in model group, these cells increasedevidently, which were mainly the macrophages in lamina propria of colon. Compared with those in modelgroup, the positive cells decreased markedly in electro-acupuncture group (P<0.05), and decreased moremarkedly in mild moxibustion group and in herbs-partition moxibustion group (P<0.01). There werestatistically significant differences between herbs-partition moxibustion group and electro-acupuncture group(P<0.05).CONCLUSION The mechanism of acupuncture and moxibustion may be that inhibited macrophageactivation, reduced expression of IL-1β and TNF-a and thereby blocking their further activation and thencontrolled, the initiated inflammation and its immunity cascade reaction and resulted in restoring the normalimmunity function and benefited in healing of ulcer.
