Objective To investigate the factors in association with colorectal disorders in adult recipients of liver allograft. Methods A retrospective cohort study was carried out with clinical, microbiological and management data regarding diarrhea in 218 adult recipients of liver allograft from Jan. 2003 to Dec. 2006. Results Of the 218 patients, 68(31.2%) of them, who did not history of ulcerative colitis, were found to have diarrhea after orthotopic liver transplantation. Among these 68 patients, diarrhea was probably caused by administration of immunosuppressive agents in 35 cases (51.4%), in 12 cases (17.6%) diarrhea was antibiotics associated, and in 5 cases (7.4%) it was due to intraperitoneal infection. The other pathogenic factors included fungal infection in 3 cases (4.4%), cytomegalovirus infection in 3 cases (4.4%), Roux-en-Y choledochojejunostomy in 8 cases (11.8%) and some other unknown problem related in 2 cases (2.9%). Diarrhea occurred soon after transplantation in most cases. Of the 68 patients, the symptom of diarrhea occurred in the first 2 months in 45 cases (66.2%), and in the next 4 months in 23 cases (33.8%), i.e. the symptoms occurred 5-180 days after transplantation. Conclusion Immunosuppressive agents, antibiotics, fungal infection and cytomegalovirus infection are the top four common causes of diarrhea after orthotopic liver transplantation. The outcome is good with appropriate conservative management.

Objective To observe the effects of ulinastatin on the expressions of tumor necrosis factor-α (TNF-α) in the lung tissues of rats with acute lung injmy induced by phosgene, and to explore the mechanism of ulinastafin in treating acute lung injury. Method Sixty-four clean grade healthy male SD rots were randomly divided(random number) into eight groups with eight in each group. Group A1 in which rats were exposed to air. Group A2 in which rots wereexposed to air and treated with saline. Group A3 in which rats were exposed to air and treated with dexamethasone. Group A4 in which mrs were exposed to air and treated with ulinastatin. Group B1 in which rots were exposed to phosgene without treatment. Group B2 in which rats were exposed to phosgene and treated with saline. Group B3 in which rats were exposed to phosgene and treated with dexamethasone. Group B4 in which rats were exposed to phosgene and treated with ulinastatin. The expressions of TNF-α in the lung tissues were measured by using immunohistocheistry. Lung tissues were observed grossly and under 200-fold light microscope to identify the positive expressions in kytoplasm. Results In group B1 and group B2, the wet weight, dry weight and wet/dry weight ratio og right lower lobe of lung were higher thai those in group A1 and group A4( P <0.01 ), and those in group B4 and group B3 were significantly lower than those in group B1(P<0.01 ), but still higher than those in group A1 and A4(P<0.01). The gross observation suggested that the surfaces of lung tissues in group A1and group A2 were slick and rose pink without congestion, dropsy or infarction; the surfaces of lung tissue in groups B1 and B2 appeared with congestion, dropsy and many petechia. The surfaces of lung tissue in groups B3 and B4 were similar to those in groups B1 and B2. Under the light microscope, the structure, of lungs in groups A1 and A2 were clear without congestion, effusion or inflammatory cell infiltration. In groups B1 and B2, the engorgement of lung capillary vessels, congestion and tiny thrombosis were found and there abundant edematous fluid and inflammatory cell infiltration in lung stroma and alveolus with focal pulmonary atelectasis in some lung tissue section. The tissues in groups B3 and B4 showed congestion, dropsy, tiny thrombosis and inflammatory cell infiltration, but these changes were slighter than those in groups B1 and B2. The expressions of TNF-α in groups B1, B2, B3, and B4 were significantly higher thanthose in groups A1 and A2( P < 0.01 ), but the expressions of TNF-α IN group B4 was lower than that in groups B1 and B2(P<0.01). Conclusions Ulinastatin could lessen the lung injury by reducing the expressions of pro-inflammatory cytokines such as TNF-α.

AIM: To observe the influence of the selective decontamination of the digestive tract (SDD) and caecosomy/colonic irrigation on gut endotoxin/bacteria translocation following acute severe pancreatitis (ASP). METHODS: Twenty three pigs weighing 16-22 kg were divided into four groups. Group I (n=5): sham-control; Group Ⅱ (n=6): ASP-control; Group Ⅲ (n=6): gntamicin [(8.55?10~5?5.70?10~4) units/time] and nystatin [(1.37?10~5?9.00?10~3) units/time] were fed orally every 8 h for 1 week before the induction of ASP; Group Ⅳ (n=6): caecostomy was performed before the induction of ASP. ASP was induced by infecting 1 mL/kg BW of combined solution of 5% sodium taurocholate and (8-10)?10~6 BAEE units/L of trypsin into pancreas via pancreatic duct. Systemic plasma endotoxin levels were quantified by the chromogenic limulus amebocyte lysate (LAL) technique. Specimens of tissue from mesenteriolum and mesocolon lymph nodes, lung, lymph nodes in hilus pulmonis, pancreas and the samples of both portal and systemic blood were collected before and at 72 h following ASP and cultured for aerobic as well as anaerobic bacteria growth. Positive specimens were subcultured and the bacteria identified by standard procedure. RESULTS: Preventive SDD not only effectively reduced the amount of bacteria in stool (P

Objective To explore the effects of endoplasmic reticulum (ER) stress in the hyperoxia-induced lung injury in premature rats. Methods Forty-eight premature Wistar rats were randomized into two groups 12 hours after birth:hyperoxia group (n=24) inhaled 95%oxygen and control group (n=24) inhaled air. Eight rats were sacriifced in each group on day 1, 3, 7 after the treatment and the left lungs were embedded. The pathological changes in the HE stained sections of lung tissues were observed. The expressions of ER related protein ERp57 and c/EBP homologous protein CHOP were detected by immuno histo-chemistry and the apoptosis of lung cells was detected by TUNEL analysis. Results The typical pathological characteristics of acute lung injury were observed in hyperoxia group. The expressions of ERp57 and CHOP were increased with the exposure time in hyperoxia group, and were signiifcantly higher than in control group (P<0.05). The apoptosis rate of lung cells in hyperoxia group was signiifcantly higher than in control group (P<0.01). There was signiifcant positive correlation between cell apoptosis index and expressions of Erp57 and c/EBP homogeneous protein. Conclusions ER stress initiated apoptosis participates and plays an important role in the process of hyperoxia-induced lung injury in premature rats.
