Preservation of Bile Ductules Mitigates Bile Duct Loss

The finer branches of the biliary tree (FBBT) contain a regenerative compartment. We hypothesized that preservation of the FBBT together with its microvasculature will lead to recovery of biliary damage and prolonged preservation of bile ductules during the development of chronic liver allograft rejection. The interlobular bile ducts, portal bile ductules and extraportal biliary cells with and without microvessels were studied in sequential biopsies in five patients who fulfilled the Banff criteria of early chronic rejection (CR) (imminence group). Biopsies of CR patients (n = 12) served as controls. Biopsies were double immunostained with CD34 (microvessels) and cytokeratin 7 (biliary structures). Proliferation and proangiogenic activity were assessed with Ki67 and VEGF-A immunostaining. Severe damage of bile ducts in the imminence group did not progress to significant bile duct loss. This was associated with a high proliferative activity in all biliary structures and preservation of the microvascular compartment. VEGF-A expression was increased in all but the reperfusion biopsies. In conclusion, both regenerative activity of the FBBT and an intact microvascular compartment are associated with less damage of the biliary tree and could therefore be prerequisites for biliary regeneration.     

Distal Penile Gangrene in a Patient with Chronic Renal Failure

To date, only 10 cases of distal penile gangrene in patients with chronic renal failure have been reported. This rare condition is believed to result from progressive vascular calcification due to secondary hyperparathyroidism in patients with chronic renal failure. We report an additional case of distal penile gangrene in a 41-year-old man who presented with chronic renal disease and pulmonary tuberculosis. Since some authors have emphasized that aggressive surgical treatment in such cases has a significant mortality rate, we took a more conservative approach to treatment.     

电镜下的乙型肝炎表面抗原

本文对81例乙型肝炎病人的肝活检组织进行了电镜观察,发现HBsAg的阳性率达93.8％。电镜下,HBsAg细丝不仅有一般的管状细丝型,还有分枝管型和管泡型,而且CAH病人肝组织不易找到HBsAg丝(易见者仅9％),CPH,CLH则多数(79.5％)为易见及可见,二者有高度显著性差异(P<0.01)。     

The effect of increasing the dietary fibre content of diets of patients with chronic renal failure treated by haemodialysis at home

The study described tested the hypothesis that increasing amounts of dietary fibre (DF) in the diet of patients on haemodialysis (HD) may achieve positive clinical benefit without adversely affecting serum potassium and plasma phosphate. The current diet of 20 home HD patients was supplemented with 15g unprocessed wheat bran incorporated into three 'bran muffins' eaten daily for a trial period of 28 days. During this period patients reported an improvement in bowel habit. Serum potassium decreased slightly but not significantly ( P =0.242) but there was a significant rise in plasma phosphate ( P =0.004). These findings suggest that when increasing DF in devising HD dietary regimes, plasma phosphate is possibly the more sensitive biochemical variable following introduction of wheat bran.     

异体甘油保存皮与自体微粒皮复合移植的临床应用

目的：寻找深度大面积\烧伤的早期治疗方法。方法:大面积深度烧伤于4－5天即行切痂，以异体甘油皮为支架，将有限的自体皮制作成微粒皮后均匀地复合植于创面。结果：对5例共12个肢体2个躯干进行早期切痂后异体甘油皮＋自体微粒皮的复合移植，成活后的创面平堤，外观平整，颜色淡红或近拟正常皮肤，触饮，收缩少，结论：异体甘油保存皮＋自体微粒皮复合移植是大面积深度烧伤较理想的治疗方法。     

Cranial nasal bone grafts

Reconstitution of the nasal scaffolding with maintainence of soft tissue proportions either following severe facial trauma or as a sequela to aesthetic rhinoplasty misadventures frequently is best achieved using the stability afforded by bone grafts. Split cranial bone grafts offer many advantages and may be the donor site of choice, and may even allow such surgery to be performed on an outpatient basis in some cases. The use of miniplate or screw osteosynthesis, now commonly accepted as a superior technique in craniomaxillofacial procedures, may simplify fixation of these calvarial nasal bone grafts with an apparent decrease in the risk of resorption.
