RESUMO
Visceral myopathy is a rare disorder characterized by atrophy,losing and fibrosis of visceral smooth muscle.Digestive tract is often invaded by the lesions,and the symptoms are various according to different lesions and degrees.Small intestinal involvement is characterized by abdominal distension,diarrhea and vomiting.Colon involvement is characterized by chronic intestinal pseudoobstruction.Malnutrition and hypoproteinemia may be secondary to this disease.The diagnosis of visceral myopathy is difficult,paralytic ileus,chronic constipation and systemic sclerosis must be considered in the differential diagnosis.The progression of the disease is slow,and the longterm prognosis is poor.In this article,the diagnosis and treatment of visceral myopathy causing acute intestinal pseudoobstruction were introduced based on the clinical data of 1 patient.
RESUMO
Gastric cancer carcinogenesis is a multifactorial process which is related to an interaction of host factors,Helieobacter pylori (Hp) infection,dietary factors and so on.The plant polyphenols which are widely present in many plants are the general term for a large group polyphenolic compounds.They have strong antioxidant activity.Furthermore,many animal experiments and clinical studies have proved that the polyphenols could inhibit gastric cancer via inhibiting Hp infection,suppressing the expression of nuclear factor-κB (NF-κB),promoting apoptosis in cancer cells and so on.The application of plant polyphenols could broaden the approaches for chemoprevention of gastric cancer.
RESUMO
Objective To evaluate the efficacy and safety of somatostatin and ileus tube for adhesive bowel obstruction.Methods From January 2008 to February 2010,ninety-one patients diagnosed with adhesive bowel obstruction were enrolled in the study.Patients were randomly divided into four groups:somatostatin + ileus tube group ( group A,n =22 ),somatostatin + nasogastric tube group (group B,n=19),ileus tube group (group C,n=23),and nasogastric tube group (group D,n =27).All cases received conventional treatment,including fasting,maintaining electrolyte and acid-base balance,enteral and parenteral nutrition support and antibiotics; Groups A and B received somatostatin 0.6 mg/day,groups B and D received nasogastric tube decompression.ANOVA analysis and x2 test were used to compare the variables.Results Group A had a quick recovery of flatus and stool compared with group D,[ (4.5 ±1.9) vs.(7.8 ± 1.7) d] (F =28.715,P =0.000).Abdominal pain and abdominal distension recovered faster [ (3.6 ± 1.5) vs.(8.4 ± 2.2) day ] in group A compared with group D ( F =23.857,P =0.000).Less amount of gastric drainage were observed in somatostatin-treatment groups [ group A vs.C:(632 ±102) ml/d vs.(1020±148) ml/d; group B vs.D:(410±86) ml/d vs.(590±97) ml/d] (F=11.687,P =0.000;F=10.399,P =0.000).The rate of laparotomy in group A was O,which was significantly less than the 22％ in group D ( x2 =5.571,P =0.018 ).Conclusions The high improvement rate in abdominal symptoms suggested the efficacy of somatostatin and ileus tube in patients with small bowel obstruction.The application of somatostatin combined with ileus tube improves the symptoms of adhesive intestinal obstruction and decreases the rate of laparotomy.
