Abstract BACKGROUND: Calcium dobesilate (calcium dihydroxy-2, 5-benzenesulfonate) has been widely used to treat chronic venous insufficiency and diabetic retinopathy, especialy many clinical studies showed that calcium dobesilate as vasoprotective compound ameliorates renal lesions in diabetic nephropathy. However, there are few literatures reported calcium dobesilate in the treatment of chronic renal alograft dysfunction after renal transplantation. OBJECTIVE:To observe the efficacy and safety of calcium dobesilate on chronic renal dysfunction after renal transplantation. METHODS:A total of 152 patients with chronic renal alograft dysfunction after renal transplantation were enroled from the Military Institute of Organ Transplantation, Changzheng Hospital, Second Military Medical University of Chinese PLA. They were randomly divided into the treatment group (n=78) and the control group (n=74). Patients in the treatment group received 500 mg of calcium dobesilate three times daily for eight weeks. Al patients were treated with calcineurin inhibitor-based triple immunosuppressive protocols and comprehensive therapies. RESULTS AND CONCLUSION: For patients receiving calcium dobesilate, serum creatinine, blood urea nitrogen and uric acid decreased significantly at two weeks after treatment and maintained a stable level (P < 0.05). However, serum creatinine and blood urea nitrogen returned to the original level soon after drug withdrawal. No significant difference was observed in blood cel count, liver function, blood lipids, electrolytes, blood pressure and 24-hour urine output between the two groups before and after therapy (P > 0.05). Administration of calcium dobesilate did not change the general condition of patients with renal insufficiency, nor did it affect blood concentrations of the immunosuppressive agents. Calcium dobesilate may help to delay the progress of graft injury in patients with chronic renal graft dysfunction by conjugating with creatinine, ameliorating the impaired microcirculation and its antioxidant property. The decline in serum creatinine aleviates patients’ anxiety and concern arising from the elevation of creatinine. However, the negative interference with serum creatinine caused by calcium dobesilate should be cautious in order to avoid misjudgment of patients’ condition.

Objective To investigate the safety and long-term therapeutic results of anatomical hepatectomy for hepatocellular carcinoma (HCC).Methods 90 patients underwent anatomical hepatectomy from January,2003 to January,2010.The tumor size was ≤5 cm in 38 patients,and ＞5 cm in 52 patients.The tumor number was a single lesion in 58 patients,and multiple lesions in 32 patients.Cirrhosis was present in 46 patients (55.42％); cancer embolus was present in 34 patients (37.78％).There were 64 patients in Child-Pugh A and 26 patients in B.The operating time,blood loss and blood transfusion were recorded and analyzed.Complications and liver function were monitored after surgery.The Kaplan-Meier method was used to calculate the survival rates.Log-rank test was used to analyze factors associating with postoperative recurrence.Independent factors influencing tumor-free survival and overall survival were analyzed by Cox-model logistic regression.Result There was no perioperative death.The incidence of complications was 31.1％ (28/90).The recurrence rate was 51.1％ (46/90).The 1-,3-,5 year tumor-free survivals were 92.2％,67.3％ and 49.7％％00,respectively.Positive resection margin and satellite nodule were independent factors for recurrence (RR19.22,95 ％ confidence interval 5.85～63.17).The 1-,3-,5-year overall survivals were 94.4％,80.0％ and 60.0％,respectively.Positive resection margin and TNM were independent factors for overall survival (RR 2.013,95％ confidence interval 1.28～3.17).Conclusions Anatomical hepatectomy was a safe and efficacious procedure to treat HCC.Positive resection margin and TNM were independent factors associated with overall survival.Anatomical hepatectomy had the advantages in ensuring a lower rate of negative resection margin.

Objective To investigate the correlation between urine levels of IP-10,Mig,OPG and the occurrence of renal allograft rejection.Methods As a retrospective nested case-control study,biopsy confirmed acute rejection reaction by 20 cases was rejection group,and recovery of renal function in kidney transplant after the elect good by 20 cases was control group.morning urine was tested of IP-10,Mig and OPG level of the two groups within 30 d after transplantation.The advantage was taken of the Luminex 2000 test platform,through PlexMark triple kidney injury marker kit to detect the daily urine of recipients.Results The rejection group's urinary IP10 wa (394.7 ± 67.3)ng/L,significantly higher than that in the control group of (10.9 ± 3.8) ng/L (P＜0,05).Urine Mig level of rejection group was (443.0 ± 88.9) ng/L,and the control group was only (15.7 ± 6.99)ng/L.Rejection group was significantly higher than that in the control group (P＜0.05).Urine OPG peak levels,the difference between the two groups was not statistically significant.Rejection group in the rejection period urinary IP-10 and Mig levels were significantly non-exclusion period,the difference was statistically significant (P＜0.01) higher than its level at different times with serum creatinine concentration showed obvious correlation,IP-10 with serum creatinine of correlation coefficients (R2)=0.8673,P＜0.01,Mig and serum creatinine R2 =0.7951,P＜0.01,IP-10 and Mig change time earlier than serum creatinine,to the exclusion of the before and after OPG differences no statistically significant.Conclusion The increasing of IP-1O and Mig content in the urine is associated with acute renal allograft rejection,which is an early reflect of subclinical tubular injury.And its changes as early as elevated serum creatinine,is expected to become independent indicators to predict acute rejection reaction occurs.

Objective To investigate the practicability and safety of laparoscopic anatomical hepatectomy.Method 40 patients with space occupying lesions in the liver underwent laparoscopic anatomical hepatectomy between Jan.2008 and Mar.2012.The diagnoses were hepatocellular carcinoma (HCC) (n=13),recurrent HCC (n =1 ),cholangiocarcinoma ( n =1 ),metastatic cancer ( n=6),hepatolithiasis (n=10),hemangioma (n=7),FNH (n=1) and liver cell adenoma (n =1).Intraoperative ultrasound was routinely performed to locate lesions and intrahepatic structures.Selective hemihepatic vascular occlusion was applied during resection. High frequency cautery,CUSA and Ligasure were used to transect liver parenchyma. Hemolocks were applied when large blood vessels and bile ducts were encountered.Endo-GIA was used if necessary.The operations included right hemihepatectomy (n =3),left hemihepatectomy (n =10),resections of segment Ⅴ and Ⅵ (n=5),segment Ⅴ (n=3),segment Ⅵ (n =4),and segment Ⅳb (n =1).Result34 hepatectomics were performed laparoscopically.6 patients were converted to open surgery.There was no perioperative death. The operating time was 250.21±50.94 min,and intraoperative blood loss was 420.20± 120.10 ml.Bile leakage was diagnosed in 2 patients after operation.Conclusion With careful patient selection,and improvement in surgical technique and apparatus,laparoscopic anatomical hepatectomy has become safe and practicable.The operation has the advantages of minimal invasion and rapid recovery. It can be regarded as a standard procedure for selected benign and malignant lesions.

Objective To compare the efficacy and safety of conversion from CCB to ARB in the treatment of hypertension and proteinuria in kidney transplant recipients.Methods 127 long-term recipients who used CCB as their anti-hypertensive drug were enrolled.All recipients had stable renal function and no diabetes.Recipients were randomly assigned to experimental group (65 cases) which received ARB (Losartan,50～ 100 mg/day) instead of CCB,or control group (62 cases) which received routine CCB.All recipients were followed up for 2 years.Blood count,urinalysis,liver and kidney chemistry,blood lipid,serum electrolytes,24-h urine protein,blood concentration of CNI drugs and other biochemical indexes were observed.Results During the 2-year follow-up,the blood pressure of the two groups was maintained within normal level.The 24-h urine protein was decreased in the experimental group ( 176.32 ± 54.54 to 155.69 ± 62.25,P＜0.05),but increased slightly in the control group (P＞0.05).Although the blood lipid of the experimental group was not different before and after the follow-up,the high density lipoprotein (HDL) was increased statistically (2.25 ± 0.26 to 2.46 ±0.31,P＜0.05).The blood count,liver and kidney chemistry,serum potassium,blood concentration of CNI drugs in both groups showed no significant differences.Conclusion Both CCB and ARB could be effectively and safely used for the treatment of hypertension and proteinuria in kidney transplant recipients.ARB would be more effective in reducing cardiovascular disease (CVD)rate and decreasing proteinuria.

Objective To investigate the efficacy and safety of conversion therapy to mizoribine (MZR) for renal transplant patients who suffered MMF or Aza adverse reaction. Methods In 56 patients with adverse reactions at different time points after renal transplantation, there were 23 cases of pulmonary infection, 14 cases of bone marrow depression, 6 cases of hepatic functional lesion and 13 cases of diarrhea. The immunosuppressive protocols of these patients were changed to CNI + MZR + Pre when the adverse reaction occurred. During the follow-up period (11 to 53 months), the effect and adverse events of conversion treatment were observed. Results After conversion treatment, 1 of 23 patients with pulmonary infection was re-infected after 26 months and finally died of heart and lung function failure. In 14 patients with bone marrow depression, blood test returned to normal in 13cases. Six patients with hepatic functional lesion were administered hepatoprotection treatment and their liver function was restored without recurrence of impaired liver function. All 13 patients with diarrhea were relieved without recurrence. The serum creatinine was 123 ± 21.3 μmol/L and 119±18. 2 μmol/L before and after the conversion therapy respectively (P＞0. 05). During the follow-up period, all patients' graft function was good. The incidence of rejection was 1.7 % (1 case). Nine patients (16. 1 %) had a higher level of uric acid after conversion. One patient had finger and toe joint pain. The symptoms were relieved after symptomatic treatment. Conclusion There were high security and good effect of conversion therapy to MZR due to MMF or Aza adverse reaction. Besides, MZR conversion therapy for renal transplantation patients provided a new option for individual immunosuppression.
