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 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 surgical procedure of restoring stenosed hilar bile duct by gallbladder lamella with cystic artery.Methods Based on extensive incising and hilar cholangioplasty,stenosed hilar bile duct was restored by gallbladder lamella with cystic artery.Results Among all the 12 pa tients,including 10 intrahepatic bile duct calculi patients,1 right hepatic duct injury and 1 left intrahepatic chaolangiocarcinoma,no cystic fistula,reflexed cholangitis and recurrent stone were noticed by post operative follow-up.Conclusion This procedure is a ideal method by remaining the normal function of Oddis sphincter while removing stenosis.

Objective To explore the relationship between dipeptidyl peptidaseⅡ(DPPⅡ) and the pathogenesis of congenital cataract.Methods Eighty SCR rats with congenital cataract were randomly divided into four groups:8,10,12 and 14 weeks groups(n=20).Normal Wistar rats at each age were used as control groups.Immunohistochemical experiments using the streptavidin-biotin immunoper-oxidase method were used to observe the immunoreactivity changes of DPPⅡ in lens in SCR rats at different time(8,10,12,14 weeks).Results The immunoreactivities of DPPⅡ in the lens epithelial cells and fibres of cataractous lenses of all ages were higher than those in control groups.At the 12th and 14th week,immunoreactive staining of DPPⅡwas found to extend into the perinuclear region.Conclusion The immunoreactivity of DPPⅡ is enhanced in cataractous rat lenses.DPPⅡ may be participated in the proteolytic modification of lens proteins during cataractogenesis.

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.
