ABSTRACT
Six patients with POEMS syndrome who received autologous peripheral blood stem cell transplantation (auto-PBSCT) were retrospectively analyzed.Conditioning regimen was high dose melphalan.Peripheral blood stem cells were collected after mobilization with cyclophosphamide (CTX) and growth factors.One patient presenting hydrothorax and ascites was treated with 3 cycles of lenalidomide and dexamethasone before mobilization.Auto-PBSCT was fairly tolerable.Hematopoietic reconstitution was successful in all patients without transplantation-related mortality.A decrease or normalization of serum vascular epithelial growth factor (VEGF) was observed in all patients at 3 months after transplantation.The neurological remission was seen in 5/6 patients.
ABSTRACT
We report two rare cases of multiple myeloma (MM) with dural intracranial disease and TP53 deletion. The two patients presented with skull lytic lesion and dural involvement of myeloma. The association between intracranial involvement in MM and TP53 deletion has not been determined. The two patients received bortezomib-based intensive induction and got good response, just as that reported in literature. MM presenting with dural intracranial disease and TP53 deletion at diagnosis is associated with poor outcome. Multi-drug regime containing bortezomib followed by autologous or allogeneic stem cell transportation would improve the prognosis.

Objective To investigate the clinical features of primary gastric lymphoma(PGL)combined with acute upper gastrointestinal hemorrhage,and to improve the diagnosis and treatment level.Methods The clinical manifestations and treatment of 2 PGL cases combined with acute upper gastrointestinal hemorrhage were analyzed retrospectively,and the related literature was reviewed.Results Two patients suffered from venosity,abdominal pain and weight loss,which were diagnosed by gastroscopy mucosa biopsy with upper gastrointestinal hemorrhage and uncontrolled hemorrhagic shock.Vascular embolization was used to stop bleeding and systemic chemotherapy was followed to achieve further curative effect.Conclusion Embolization treatment is safe and effective for PGL combined with acute upper gastrointestinal hemorrhage without any influences on chemotherapy.

ABSTRACT
Objective To evaluate effects and possible mechanisms of ileal transposition on spontaneous non-obese type 2 diabetic GK rats.Methods 20 GK rats were randomly divided into two groups:ileal transposition group and sham operation group (n =10).We observed and determined the weight change,daily average food consumption and FBG (fasting blood-glucose) level of rats before the operation (0 weeks) and 1,4,8,16 and 24 weeks after the surgery.Glucose tolerance test (GTT) was carried out and GLP-1 (glucagon-like peptide-1) concentration measured before the operation (0 weeks) and 4,8,16 and 24 weeks after the surgery and the fasting insulin concentration before the surgery (0 weeks)and 4,24 weeks after the surgery measured,and the indicator of HOMA-IR calculated.Results There was no significant difference in the operating time between the two groups [(87 ± 8) min vs.(84 ± 7)min],P ＞ 0.05.Compared with those before surgery,body weight and food consumption of the two groups of rats decreased significantly a week after surgery (P ＜ 0.05),and then the body weight and food consumption of the two groups of rats all gradually increased,but the difference of the two groups of rats has no statistical significance 1-24 weeks after surgery (P ＞ 0.05).The FBG of the two groups of rats a week after surgery [ileal transposition group (6.1 ± 0.6) mmol/L,sham operation group (6.2 ± 0.8) mmol/L]decreased significantly compared with that before surgery [(7.0 ± 0.5) mmol/L and (6.9 ± 0.5) mmol/L](P ＜ 0.05),and then FBG of the two groups of rats all rose again.The FBG of the rats in surgery group decreased slowly from 8 to 24 weeks after surgery,while the FBG of the rats in the sham surgery group maintained the preoperative level,and the differences of the FBG of the two groups all have statistical significance 8-24 weeks after surgery (P ＜ 0.05).Four weeks after surgery,OGTT of the ileal transposition group significantly improved (P ＜ 0.01).24 weeks after surgery,fasting insulin levels of the ileal transposition group were lower [(0.26 ± 0.08) ng/mL vs.(0.42 ± 0.09) ng/ml],P ＜ 0.05.Compared with the sham surgery group,and HOMA-IR was lower (1.1 ± 0.4) vs.(2.6 ± 0.4),P ＜ 0.05.Four weeks after surgery,oral glucose-stimulated peak (30 min) levels of blood GLP-1 increased markedly in operation groups after surgery (P ＜ 0.01).Conclusions Ileal transposition is effective for the treatment of non-obese T2DM rats,and the control of blood glucose does not depend on the reduction of body weight and food comsumption,and the high secretion of GLP-1 after ileal interposition seem to be helpful in diabetes control.
ABSTRACT
Objective To study the diagnosis and surgical treatment of Mirizzi syndrome (MS).Method The clinical data of patients with Mirizzi syndrome treated in our center from July 2001 to July 2011 were retrospectively studied and the diagnostic methods,operative strategies and outcomes of surgical treatment were analyzed.Results Mirizzi syndrome (MS) was identified in 56 out of 13800patients who received cholecystectomy (0.4％). MS was diagnosed preoperatively in 30 patients (53.6％).There were 29 patients with Mirizzi syndrome type Ⅰ,17 patients with type Ⅱ,9 patients with type Ⅲ,and 1 patient with type Ⅳ using the Csendes's classification.In two patients (3.6％) coincidental gallbladder carcinoma was detected.An initial laparoscopic approach was attempted in 33patients,and 16 were converted to open surgery.The remaining 23 patients underwent open operation.Surgical procedures included cholecystectomy,choledochotomy and T-tube insertion,simple closure and drainage (via T tube) of the biliary fistula,Roux-en-Y hepaticojejunostomy,radical resection of gallbladder and hepaticojejunostomy.Inadvertent bile duct injury occurred in 2 patients who had an initial laparoscopic approach for a preoperative undiagnosed MS. Postoperative morbidities included biliary leak (n =4) and residual common bile duct stone (n=2).All patients recovered completely and there was no hospital mortality.Conclusions Preoperative diagnosis of Mirizzi syndrome is still challenging despite the availability of multiple imaging modalities.Open surgery remains the standard of care,although laparoscopic treatment may be used in selected patients,especially for type Ⅰ Mirizzi syndrome.Patients with Mirizzi syndrome should be managed differently,basing on intraoperative findings and the type of Mirizzi syndrome.
