Objective To report the experience in diagnosing gastroenteric tuberculosis under en-doscopies, and arose enough attention to avoid missed or mis-diagnosis. Methods Biopsy is taken when lesions, such as gastroenteric mucosal protrusions, nodule, erythema and ulcer are found under endoscopies. Results In 7 cases studied, 2 of them are the gastric tuberculosis (1 ulceration, 1 proliferation) , the rest, colonic tuberculosis (4 proliferation and 1 mixed). Distribution of lesions: gastric antrum 2, each one in terminal ileum, ileocecal valve, terminal ileum plus ileocecum, terminal ileum plus pan colon, and ascending colon. Endoscopic diagnosis: colonic tuberculosis with infiltrative tuberculosis in both lungs 1; colonic malignant tumors 2, mucosal protrusions and ulcerative lesions with undefined nature 4. Caseous necrotic granu-lomas are found in all cases on pathological examination. Conclusion The various appearances of gastroenteral tuberculosis under endoscopies are hard in differentiating from those of colonic carcer, inflammatory bowel diseases ( Crohn' s disease etc. ) , gastric benign or malignant ulceration. The definite diagnosis of gastroenteral tuberculosis is greatly depended on pathological results.

Coagulopathy is very common in patients in intensive care unit (ICU) and often indicates organ dysfunction or underlying diseases.The application of traditional methods assessing the patients' coagulation status in ICU is limited because they can not reflect the whole process of coagulation.Thromboelastography (TEG),a point-of-care (POC) assay of coagulation,fibrinolysis and platelet function,developed in recent years has been widely used in organ transplant and cardiovascular surgery and so on.However,there is no standard for the use of TEG in ICU.The development and application of TEG in sepsis,multiple trauma,guiding blood transfusion,extracorporeal membrane oxygenation (ECMO),and anticoagulation monitoring were addressed in this review,and its value and application prospect in ICU were analyzed.

Forty-five patients with burn area exceeding 30% TBSA were studied prospectively. Among these 45 patients, 13 developed multiple organ failure (MSOF). Blood superoxide, dismutase (SOD) activity and plasma malondialdehyde (MDA) levels were sequentially determined to assess the role of excessive release of oxygen radicals and lipid peroxidase injury in the mechanism of pathogenesis of postburn MSOF. The results showed that the anti-oxidation capacity of the body was markedly depressed and lipid peroxidase injury markedly increased after a severe burn injury. These changes were not only related to hypovolemic shock after the injury, but also the severity of the burn injury and infection.
