Objective To investigate the relationship between histopathological changes of donor liver and those after liver transplantation and explore its effects on prognosis.Methods The histopathological changes of donor liver and post-transplantation live biopsy were observed in 87 cases.Results The percentage of hepatic degeneration at immediate biopsy of donor liver was 100%,the injury of sinusoid endothelial cell accounted for 41.3%,the hepatic steatosis for 18.3%and the necrosis of liver cells for 10.3%.Conclusion Most of the pathological changes of the donor liver during and after liver transplantation are reversible.The damage of the hepatic sinusoidal cells is the important criterion for the observation of ischemia reperfusion injury.Moderate and heavy hepatic steatosis can be used in the liver transplantation. After liver transplantation,if the necrosis of liver cells gradually gets serious,the risk of transplanted liver losing its function gets bigger,so the comparative observation has very important value in diagnosis.

Objective To explore the feasibility of minimally invasive video-assisted thyroidectomy (M IVAT). Methods Clinical data of 8 consecutive patients with ben ign thyroid nodules treated by MIVAT in this hospital from September 2002 to Sep tember 2004 were retrospectively reviewed. Results All the pro cedures were successfully completed. The operative time was 90~150 min (mean, 12 0 min), and the hemorrhage volume, 10~30 ml (mean, 20 ml). No complications happ ened and no conversions to open surgery were needed. All the patients were compl etely recovered and discharged from hospital 3~4 days after the surgery. Follow- up checkups for 6~12 months (mean, 9 months) in the 8 patients found normally he aled wounds and no paraesthesia. Conclusions MIVAT is safe and effective, with excellent cosmetic outcomes.

Objective: To explore the protections of GLP-Ⅱ pretreatment on mouse intestinal mucosal immunity after ischemia/reperfusion insult. Methods: Thirty ICR mice were randomly divided into three groups: namely normal control (N), control (C) and GLP-Ⅱ pretreatment (P). Group C and group P were inflicted with ligation of superior mesenteric artery for twenty minutes. The morphology of distal ileum mucosa, the rate of intestinal bacteria translocation, the level of plasma endotoxin and intestinal IgA were determined. Results: After ischemia/reperfusion insult, there were obvious damage at distal ileum mucosa in group C and obvious proliferation in group P.The rate of intestinal bacteria translocation and the level of plasma endotoxin were significantly increased (P

Objective To investigate Bcl-2 expression in the peripheral blood mononuclear cells and its clinical significance of liver fibrosis (LF). Methods Tested Bcl-2 protein levels in T, B cells of 47 patients (male 17, female 30) with LF, 35 patients (male 24, female 11) with chronic hepatitis B and no LF and 41 cases (male 29, female 12) normal controls by two color cytofluorography. Results Among them, LF patients, chronic hepatitis B without LF and normal controls, the proposition of T cells (including CD3~+, CD4~+ and CD8~+ subgroups) and CD19~+ B cells expressed Bcl-2 protein increased significantly in LF patients (P

Objective To study the effect of glucagon-like peptide 2 (GLP-2) on the absorption- related genes [ sodium dependent glucose transporter 1 (SGLT1) and dipeptide transporter 1 (PEPT1)] mRNA expressions of residual small bowel in a rat model of short bowel syndrome. Methods Rats undertaken 75% small bowel resection were randomly assigned into 3 groups: short bowel control (SBC) group, growth hormone (GH) group and GLP-2 group. Another weight-matched normal rats with normal diet was used as normal (NC) group. All rats were given normal chow on the 1st postoperative day (POD). On the 6th POD, partial segment of terminal ileum was harvested to evaluate the mRNA expressions of SGLT1 and PEPT1 by semiquantified reverse transcription polymerase chain reaction. Results The mRNA expressions of both SGLT1 and PEPT1 in SBC group were significantly higher than that of NC group(P0.05). Conclusions A short term GLP-2 adiministration in early postoperative days may has no significant effect on mRNA expressions of SGLT1 and PEPT1 in residual ileum in rats with short bowel syndrome.

Objective To improve the knowledge of X-ray findings of heart and lung in chronic renal failure ( CRF ) . Methods X-ray findings of heart and lung in 120 cases with CRF were analysed retrospectively.Results The X-ray appearances of lung and heart in CRF included augment and blur of hilum, increased, tortuous and disorder lung markings, accretion of heart, and the abnormal shadows in lung were irregular, inhomogeneus and changing fast in morphology. Conclusion Radiography can supply valuable messages and is ofconsiderable value in the diagnosis of CRF.

The ubiquitin-specific protease ( USP) inhibitors influence many crucial cellular activities and some immune processes, such as anti-inflammatory, anti-infection and anti-tumor by silencing the functions of USP.The main USP inhibitors, which potency and specificity are underlined and current methods for detecting and identifying USP inhibitors are discussed of in this review.
