Objective To explore the feasibility and clinical efficacy of hand assisted laparoscopic splenectomy (HALS) for ruptured spleen. Methods From January 2002 to October 2002, HALS was performed in 12 cases, among whom were 8 cases combined with other viceral trauma. Results HALS was accomplished successfully in 10 cases and laparotomy in 2. In 10 cases, the operation time of HALS averaged 102.5 minutes. The mean post operative hospitalization was 5.8 days in 4 cases with only spleen trauma and 15.5 days in 6 combined with other viceral trauma. Conclusions HALS is a feasible, effective and safe surgical procedure for the cases with Buntain CT scalingⅡ or Ⅲ spleen trauma with no severe combined trauma.

Objective To explore the feasibility and significance of hand-assisted laparoscopic splenectomy (HALS) for ruptured spleen. Methods We conducted HALS in 18 cases of ruptured spleen between January 2002 and January 2003. According to the Buntain classification of CT-graded splenic injury, 7 cases were classified as “type Ⅱ” and 11 cases, “type Ⅲ”. Ruptured spleen was complicated by other organ injuries in 12 cases. Results The operation was completed successfully in 16 cases, the operation time being 75~115 min (mean, 92.5 min). A conversion to open surgery was made in 2 cases, which were suspected of having injuries of other major vessels. Postoperative time to normal activities was 20~30 days in 6 cases of simple ruptured spleen and 30~100 days in 10 cases of ruptured spleen complicating other injuries. Conclusions HASL is feasible for “type Ⅱ or Ⅲ” ruptured spleen without severe complicating injuries.

Objective To evaluate the diagnosis and treatment of chronic pancreatitis complicated by stricture and dilation of the pancreatic duct. Methods The clinical data of 27 patients of chronic pancreatitis with stricture and dilation of the pancreatic duct undergoing operation in our hospital from 1990 to 1999 were analyzed retrospectively. Results Of the 27 patients, the positive diagnosis rate was 89% by B-US, 100% by CT, 100% by MRCP, 100% by ERCP. All patients received surgical operation, 12 patients received Partington procedure, 3 distal pancreatectomy, 4 pylorus preserving pancreaticoduodenectomy, 4 Beger procedure, 2 Frey procedure, 2 pancreatic cystojejunostmy. The complication rate was 11%. Postoperatively 89%(24/27) patients achieved pain relief,78%(18/23) gained in body weight, and diabetes significantly relieved in 5 cases(33%). Conclusion Appropriate diagnosis and treatment are very important for improving the patients′ life quality and natural history of chronic pancreatitis with stricture and dilation of the pancreatic duct.

Objective To discuss the clinical value of susceptibility weighted imaging (SWI) in the brain vascular malformations. Methods Imaging data of 34 patients with brain vascular malformations proved by digital subtraction angiography (DSA) or pathology obtained on Siemens Sonata 1.5T MR system were studied prospectively, and compared with those of conventional MRI (cMRI) and SWI. Results All 41 lesions of 34 patients with brain vascular malformations showed clearly by SWI. These patients were diagnosed by surgical findings or DSA. These nidus comprised 19 cavernous angiomas, 9 arteriovenous malformations and 6 cerebral venous malformations. Conclusion SWI should be used for clinical diagnosis of brain vascular malformations, and providing more complete and detailed information combining with other sequence.

Objective:To investigate the effects of Tripterygium Wlilfordii on renal interstitial fibrosis and the expression of inflammatory factor in mice kidney with the Unilateral Ureteral Obstruction(UUO).Methods:Mice were randomly assigned to shame operation group(shame proup), UUO group, Tripterygium Wlilfordii and ACEI treatment group after UUO. The protein expression of ?-SMA,ICAM-1 were assessed by immunohistochemistry or Western blot; MCP-1 mRNA were detected by reverse transcription-polymerase chain reaction analyses(RT-PCR). And the change of renal pathology was observed at the same time.Results:In comparison with the shame group, the protein levels of ?-SMA, ICAM-1 and the mRNA expression of MCP-1 in UUO mice and treatment groups increased significantly, meanwhile Tripterygium Wlilfordii and ACEI could significantly reduce the expression of ?-SMA, ICAM-and MCP-1 on levels of protein and gene. The effects of Tripterygium Wlilfordii on ICAM-1 and MCP-1 were more significant than ACEI.Conclusion:Tripterygium Wlilfordii could reduce the transdifferentiation of renal interstitial cells and prevent renal interstitial inflammatory injury.

Objective To explore the role of severity of limb ischemic injury in the treatment of popliteal artery injury.Methods A retrospective analysis was conducted of 259 patients with popliteal artery injury who had been treated from January 2002 to December 2014.They were 187 males and 72 females with a median age of 37.6 years (range,from 14 to 68 years).The time from injury to revascularization was from 4 hours to 29 days.According to the Rutherford classification system,the limb ischemic injury was categorized into 4 grades:grade Ⅰ:presence of sense and motion;grade Ⅱ:presence of sense but loss of active motion;grade m:loss of sense or motion;grade Ⅳ:stiffness.For all the patients with injury of grades Ⅰ and Ⅱ,limb salvage was adopted and opening decompression to osteofascial compartment was performed depending on the intraoperative and postoperative limb swelling.For the patients with grade Ⅲ injury,opening decompression to osteofascial compartment was performed to explore the activity of muscles in those with a strong will to preserve their limbs.When the muscle activity was poor but bright red bleeding was found at the broken muscle ends and there were no fish-like changes in muscles,limb salvage was suggested;otherwise amputation was chosen.For all the patients with grade Ⅳ injury,amputation was suggested.Results Of the 146 cases of limb salvages,142 were successful and 4 failed due to uncontrollable infection,giving a total success rate of 54.83% (142/259).Complete rupture of the popliteal artery occurred in 23 cases,incomplete rupture or tear in 17,contusion and thrombosis in 219.No patient died due to popliteal artery injury or its complications.The patients with injury of grades Ⅰ,Ⅱ,Ⅲ and Ⅳ were respectively 51,88,67 and 53;their success rates of limb salvage were respectively 100.00% (51/51),96.59% (85/88),8.96% (6/ 67) and 0.For the patients whose time from injury to revascularization was < 6 h,6 h to 12 h,13 h to 24 h,25 h to 1 w,and > 1 w,the success rates of limb salvage were respectively 80.77% (42/52),54.58% (73/134),20.51% (8/39),33.33% (6/18),and 81.25% (13/16).The 142 patients whose limbs had been salvaged obtained an average follow-up of 31.4 months (range,from 6 months to 8 years).Of them,those with grade Ⅰ injury obtained normal plantar sensation and active ankle flexion and extension.Of the 85 patients with grade Ⅱ injury,all recovered normal or nearly normal plantar sensation,29 achieved partial recovery of active ankle and digital flexion and extension,but the other 56 obtained no recovery of active ankle motion.Of the 6 patients with grade l injury,none obtained recovery of motion function,4 achieved partial recovery of plantar sensation but the other 2 had no recovery.Conclusion The classification of popliteal artery injury into 4 grades according to its severity of ischemic injury can provide helpful guidance to the treatment and prognosis assessment of the popliteal artery injury.

OBJECTIVE:To observe therapeutic efficacy and safety of domestic Imatinib mesylate tablet in the treatment of chronic myeloid leukemia(CML). METHODS:16 CML patients were selected,including 7 newly diagnosed CML patients and 9 patients diagnosed as CML more than 12 months. Imatinib mesylate tablet 400 mg,qd were used in all patients. Blood routine, bone marrow cytology,ph chromosome Evaluate efficacy,and observed peripheral blood fusion gene,Bcr-Abl/Abl gene mutation and ADR were all detected. RESULTS:After treatment,16 patients achieved complete hematologic remission (CHR);12 cases were pavtial cytogenetic response(MCyR),of which 2 cases achieved complete cytogenetic response(CCyR),2 cases were cyto-genelic remission. 15 patients'Bcr-Abl/Abl transcript levels were less than 10%,and only one case was more than 10%. No ADR difficult to tolerate was found in 16 patients. CONCLUSIONS:Domestic Imatinib mesylate tablet shows definite early therapeutic efficacy and high safety.
