Objective To explore the regulating mechanism of bcl 2 gene in hepatocyte injury caused by obstructive jaundice in rats. Methods Normal rats' and bile duct ligated 7d,14d,21d rats' hepatocytes were isolated by in situ collagenase perfusion and primary culture. (1) bcl 2 mRNA was detected by RT PCR in all cells; (2) After normal rat and bile duct ligated 14d rat hepatocytes were added 100?M GCDC and kept for 24hrs, cells were evaluated by FCM and TUNEL. Results (1) Normal rat hepatocytes did not express bcl 2 by RT PCR technique. bcl 2 was expressed in 7-,14-,21-day BDL rats. (2) After adding 100?M GCDC and keeping for 24hrs, the apoptosis of bile duct ligated rat hepatocytes significantly decreased compared with that of normal rat hepatocytes. Conclusions (1) Bile duct ligated rat hepatocytes expressed bcl 2. (2) Hepatocellular expression of bcl 2 during obstructive jaundice is an adaptive phenomenon to resist apoptosis by bile salts.

Objective To report our experience of nephron sparing surgery (NSS) with mini-incision approach.Methods Sixty-one mini-incision NSS were analyzed retrospectively from 2005 to 2011 in our department.Demographic and clinical data,complications,histologic and oncologic data were analyzed.There were 35 males and 26 females with average age of 41 years.B ultrasound and CT scan were performed in all cases and MR was performed in 23 cases.CT angiography was performed in 10 cases.Renal cell cancer was diagnosed in 38 cases,angiomyolipoma in 14 cases,complicated renal cyst or duplicated kidney in 6 cases and no definite diagnosis in 3 cases.All the lesions were single with 21 in the right side and 40 in the left side.The average diameter of the lesions was 3.2 (2.3-8.8) cm.The mini-flank supra-12th rib incision was performed in all cases.The renal artery was clamped with bulldog clamp,all transected blood vessels on the renal incisal surface were sutured with 3-0 Vicryl sutures,and collecting system was closed with continuous' 3-0 Vicryl suture.Results The average length of incision was 8.1 (6.5-11.0) cm.The average operative time was 93 (70-140) min.The average warm ischemia time was 19 (12-32) min.The average blood loss was 72 (20-300) ml and the average hospital stay was 6 (5-15) d.The delayed hemorrhage was occurred in 1 patient who was treated with conservative treatment.Clear cell carcinoma was found in 28 cases,chromophobe carcinoma was found in 6 cases,papillary carcinoma was found in 5 cases,angiomyolipoma was found in 16 cases,complicated cyst was found in 3 cases and renal duplication was found in 3 cases.Fortyfive patients were followed up from 28 to 82 months with no delayed complication and no recurrence or metastasis in 35 malignant cases.Conclusions The approach of mini-incision NSS can duplicate the procedure of traditional open NSS.This approach can also couple the benefits of both laparoscopic and open NSS techniques with a smaller incision which can be used to remove the specimen.
