OBJECTIVETo discuss the safety line to avoid the post-hepatectomy hepatic insufficiency by combining indocyanine green test by pulse dye-densitometry (PDD-ICG) and standard remnant liver volume (SRLV).

METHODSSeventy-five hepatic cancer patients undergone hepatectomy from March 2007 to February 2008 were included. According to the liver function decompensatory grades after operation, the relationship between ICG retention rate at 15 min (ICGR15) and standard remnant liver volume by linear regression were analyzed.

RESULTSThere were 60 cases with slight hepatic insufficiency, 12 cases with moderate hepatic insufficiency, and 3 cases with severe hepatic insufficiency. There were no difference in age [(50 +/- 13) years old and (53 +/- 9) years old], prothrombin time [(13.6 +/- 1.0) s and (13.5 +/- 1.0) s], international normalized ratio (1.09 +/- 0.10 and 1.06 +/- 0.10) between slight hepatic insufficiency group and moderate and severe hepatic insufficiency group (P > 0.05). And there were difference in K value (0.20 +/- 0.04 and 0.17 +/- 0.03), ICGR15 (6 +/- 4 and 9 +/- 4), SRLV [(545 +/- 93) ml and (398 +/- 82) ml] between two groups (P < 0.05). Compared ICG test and standard remnant liver volume of the patients with moderate hepatic insufficiency after operation, the liner relationship was found (R = 0.640, P = 0.025), and the regression equation was: standard remnant liver volume (ml/m(2)) = 1594.6 x ICGR15 + 265.

CONCLUSIONSPDD-ICG test and standard remnant liver volume are effective to estimate hepatic function reserve of patient undergone hepatectomy.

To explore the theory of "Shaoyang Meridians being in charge of the bone" in Huangdi's Internal Classic, which has been buried for long time. With citation of Huangdi's Internal Classic and exposition of famous experts, speculate on the contents and meanings systematically. Results indicate that the theory of "Shaoyang Meridians being in charge of the bone" possibly first in the world recognizes osteoporosis being a general bony disease, and articulates that the Foot-Shaoyang Meradians can modulate bony strength under physiological and pathological conditions, and treat osteoporosis which mainly manifests as ostealgia and easy fracture.

OBJECTIVETo investigate the association between transforming growth factor beta-1 (TGF-beta1) gene polymorphism and chronic allograft nephropathy (CAN).

METHODSFifty patients with failed renal allografts and clinically and histopathologically confirmed CAN were enrolled in this study along with another 50 renal transplant recipients with normal graft function. The DNA extracted from whole blood of the patients was amplified with PCR with sequence-specific primers for determining TGF-beta1 genotypes (position +869, codon 10 and position +915, codon 25). According to documented descriptions, the patients were classified into high and moderate-to-low cytokine production genotypes. The distribution frequencies of high production genotypes was then compared between CAN and non-CAN groups. To eliminate interference in the analysis of the association between TGF-beta1 polymorphism and CAN, other possible risk factors for CAN were screened, including the patients' gender, age, HLA match, delayed graft function, acute rejection, immunosuppressive regimen, cytomegalovirus infection, hypertension, and high cholesterol.

RESULTSCAN patients showed significantly greater proportion of high cytokine production genotype than the non-CAN group [70% (35/50) vs 38% (19/50), Chi(2)=10.306, P=0.001). Of the screened risk factors for CAN, only acute rejection showed some difference between the two groups, but analysis after subgrouping according to acute rejection did not suggest its influence on CAN, which supports the result that the rate of high production genotype was significantly higher in CAN group than in the non-CAN group.

CONCLUSIONMost CAN patients have high TGF-beta1 production genotype, which might be a risk factor for CAN after renal transplantation. TGF-beta1 genotyping can be of value in predicting the risk of CAN after renal transplantation.

OBJECTIVETo study the value of detection of both preoperative soluble CD30 (sCD30) and hepatocyte growth factor (HGF) level 5 days after transplantation in the diagnosis of acute rejection of renal allograft.

METHODSPreoperative serum sCD30 levels and HGF level 5 days after transplantation were determined in 65 renal-transplant recipients using enzyme-linked immunosorbent assay. The recipients were divided according to the sCD30 levels positivity. Receiver operating characteristic (ROC) curves were used to assess the value of HGF level on day 5 posttransplantation for diagnosis of acute renal allograft rejection, and the value of combined assay of the sCD30 and HGF levels was also estimated.

RESULTSAfter transplantation, 26 recipients developed graft rejection and 39 had uneventful recovery without rejection. With the cut-off value of sCD30 of 120 U/ml, the positivity rate of sCD30 was significantly higher in recipients with graft rejection than in those without (61.5% vs 17.9%, P<0.05). Recipients with acute rejection showed also significantly higher HGF levels on day 5 posttransplantation than those without rejection (P<0.05). ROC curve analysis indicated that HGF levels on day 5 posttransplantation was a good marker for diagnosis of acute renal allograft rejection, and at the cut-off value of 90 ug/L, the diagnostic sensitivity was 84.6% and specificity 76.9%. Evaluation of both the sCD30 and HGF levels significantly enhanced the diagnostic accuracy of acute graft rejection.

CONCLUSIONCombined assay of serum sCD30 and HGF levels offers a useful means for diagnosis of acute renal allograft rejection.

Objective To summarize the experience of long-term survival in patients after simulta- neous kidney-pancreas transplantation(SKPT)with modified enteric drainage(ED).Methods From October 2001 to July 2004,6 patients with end-stage renal disease due to Type 1 diabetes underwent SKPT with modified ED,ie,side-to-side anastomosis between the duodenum of donors and jejunum of recipients. The medication regimen included:mycophenolic acid 500 mg and tacrolimus 2 mg before operation;methyl- prednisolone(MP)1.0 during operation;and 2-dose anti-IL-2 receptor monoclonal antibody(2 cases)or antihuman thymocyte globulin(ATG)(4 cases)for immune induction therapy;MP was used on the first 3 d after transplantation,triple immunosuppressive therapy(tacrotimus,mycophenolic acid and prednisone)was used on the second d after transplantation.Anticoagulants such as low molecular heparin or alprostadil were used for 7-10 d to prevent thrombosis in pancreas graft.Somatostatin was used as prophylaxis for graft pan- creatitis.Ganciclovir was used to prevent cytomegalovirus infection when renal graft gradually recovered 3 to 5 d after transplantation.The follow-up was from 1 year and 3 months to 4 years and 1 month.Results Transplantation was successful in all 6 cases.The blood sugar levels were 6-16 mmol/L.Low-dose insulin was used for 5-10 d,then the blood sugar levels returned to normal range.One of 6 patients experienced nephrotoxicity because of high tacrolimus blood concentration at 7 d after operation;after 3 dialyses and re- duction of tacrolimus dose,the renal allograft regained normal function.Three cases experienced alimentary tract hemorrhage at 14,20 and 22 d,respectively,after operation;the bleeding was stopped after treatment. There were no complications such as pancreatic fistula,intestinal fistula and thrombosis early after operation. All the patients are now alive,specifically,1 survived over 4 years,3 over 3 years,1 over 2 years,and 1 over 1 year.All had normal blood sugar free of insulin use.Five cases had normal renal graft function,with normal sCr,and 1 had sCr＞400?mol/L. Two cases were admitted to hospital due to upper respiratory infection and furuncles in the skin of head 6 months and 2 years,respectively,after operation.They were both cured.No complications such as urinary infection,metabolic acidosis and dehydration occurred.Conclusions SKPT is effective for the treatment of end-stage renal disease due to Type 1 diabetes.SKPT with modified ED are relatively simple with physiological compatibility and fewer complications.High quality of donated organs, HLA matching,pancreatic drainage pattern,rational periopcrative medications and infection late after trans- plantation are important factors affecting the long-term survival of the patients.
