Objective: To analyze the experience in the treatment of intraductal papillary Mucinous tumors(IPMT) of the pancreas.Methods: We retrospectively analyzed the clinical and imageological features of 30 IPMT patients,17 males and 13 females,who underwent operations in our department from May 2003 to December 2005.The patients with intraductal papillary mucinous adenoma(IPMA) were included in the benign group,and those with intraductal papillary mucinous borderline tumor(IPMB) and intraductal papillary mucinous carcinoma(IPMC) in the malignant group.Results: There were more males than females in the malignant group(76.5% vs 30.8%,P40 mm,which were considered to be the predictors of malignancy.Conclusion: Clinical and imageological features differ signifcantly between different pathological types of IPMT.The presence or absence of mural nodules,the diameter of the main pancreatic duct and the size of the tumor may help differentiate the malignancy from benignancy of IPMT.

AIM To research effects of sodium ferulate(SF) on transforming growth factor ?_1 inhibited hepatocyte growth. METHODS Human cultured hepatocytes(L02 cells) served as control group ,TGF?_1(5 ?g?L -1 ) was used to inhibited L02 cells to construct the cell model. MTT methods were used to study the growth inhibitory effect of TGF?_1 on L02 cells. DNA synthesis was analyzed by measuring 3H-TdR incorporation. The effects of SF on the changes of cell cycle were analyzed by flow cytometry. Generation of intracellular ROS was determined by the emission of fluorescence in L02 cells proloaded with DCFH-DA fluoresin and then treated them with TGF?_1 or SF. After 4h,control, TGF?_1 and TGF?_1+SF-treated cells were analyzed by flow cytometry. RESULTS ①Incubated in the presence of TGF?_1 for 24 h, 67.93% of L02 cells survived (P

Objective To observe the changes of coagulation function in patients with acute lowerlimb deep venous thrombosis(DVT)and evaluate the risk factors for DVT. Methods Plasma APTT.PT,TT,D-dimer and fibrinogen(Fbg)were detected by an automated coagulation analyzer in 62 acute lower-limb DVT patients and 70 controls:Retrospective studies on the clinical data of all patients were done by binary logistic regression analysis.Results (1)In DVT group,plasma APTT,PT and TT,the levels of D-dimer and fibrinogen.and D-dimer/fibrinogen ratio(D/F ratio)were higher when compared with control group(au P＜0.01);(2)There were positive correlations between D-dimer and fibrinogen both in DVT and control groups(r=0.475,P＜0.01;r=0.564,P＜0.01,respectively);(3)Logistic analysis indicated that acute lower-limb DVT was associated with the presence of hypertension and increased plasma level of fibrinogen(OR=24.99,P＜0.01: OR=4.346.P＜0.01,respectively).Conclusions Hypertension and elevated plasma level of fibrinogen are independent risk factors for acute lower-limb DVT.

Objective Based on the diagnostic technique of electric meridian detection, to observe the clinical efficacy of acupuncture in treating angioneurotic headache.Method Totally 106 patients with angioneurotic headache were randomized into a treatment group and a control group, 53 cases in each group. The treatment group received acupuncture based on the electric meridian detection, while the control group received medication treatment. The hemorheology indexes [plasma viscosity (PV), erythrocyte sedimentation rate (ESR)] and McGill Pain Questionnaire (MPQ) [Pain Rating Index (PRI), Visual Analogue Scale (VAS), and Present Pain Intensity (PPI)] were observed before and after intervention, and the clinical efficacies were compared. Result The total effective rate was 88.7% in the treatment group versus 71.7% in the control group, and the between-group difference was statistically significant (P<0.05). After intervention, the hemorheology indexes and MPQ scores were significantly changed in both groups (P<0.01,P<0.05).Conclusion Acupuncture based on electric meridian detection is an effective method in treating angioneurotic headache.

Objective To evaluate the clinical value of fiberoptic ductoscopy in diagnosis and treatment of patients with galactophoritis or mammary duct ectasia. Methods From November 2005 to March 2008, fiberoptic ductoscopy were performed in 120 women with nipple discharge. The duct of 95 cases as non-malignant lesion were insufflated and perfusioned with entamycin and dexamethasone. Results Ninty-five of 120 cases were non-malignant disease,which contained one side 81 and two sides 14; the discharge was bloody,ivory, stramineous in 21, 17, 57 patinents, respectively; and the dignosis were 17 mammary duct ectasia, 53 galactophoritis, and 25 mammary duct ectasia with galactophoritis. Of the 95 cases, hich were intradutal insufflated and perfusioned with gentamycin and dexamethasone, the nipple discharge were decreased or disappeared in 81 cases, the effective rate was 85.3%. Conclusion Fiberoptic ductoscopy is a convenient,safe, accurate method in diagnosis and treatment of patients with galactophoritis or mammary duct ectasia.

Object To study the liver-protection and bile promoting secretion of gentiopicroside administrated ig in rat. Methods Gentiopicroside was administrated ig to the mice with liver injury induced by CCl 4 and D-GlaN. ALT, AST levels in serum and GSH-Px activity in liver were examined. The bile flow rate and the concentration of the main components in the bile of rats after ig administration of gentiopicroside were estimated. Results Gentiopicroside administrated ig decreased the serum ALT and AST levels, increased the liver GSH-Px activity in the mice treated with CCl 4, promoted the secretion of bile and increased the concentration of bilirubin in the bile. Conclusion Gentiopicroside administrated ig exhibited significant liver-protection and promoting bile secretion.

Objective To analyze the clinical features of rectal and perianal inflammatory myofibroblastic tumor and evaluate its diagnosis and treatment.Method Clinicopathological data of 3 cases diagnosed as inflammatory myofibroblastic tumor from January,2005 to June,2011 were retrospectively reviewed.Results Inflammatory myofibroblastic tumor presents as infiltrative growth mass with rich vascularization on CT or MRI,and is difficult to distinguish from hemangioma and other rectal tumors.Preoperative biopsy usually fails to ascertain the entity of mass,and pathological examination of the whole resected specimen with immunohistochemical staining is needed to make final diagnosis.All 3 cases underwent sphincter preserving surgery.One case received a second radical operation 16 months after primary resection because of local recurrence.All patients are followed up to now,with a survival time of 67 months,55 months,and 35 months respectively.Conclusions Rectal and perianal inflammatory myofibroblastic tumor is difficult to diagnose on preoperative imaging examinations or biopsy.Immunohistochemical staining is needed to make final diagnosis.Sphincter preserving surgery with complete tumor removal could achieve long term survival.

Objective To improve the prognosis and radical resection of the extended pancreaticoduodenectomy for patients with pancreatic cancer in the ucinate process involving mesentery mot. Methods From Jan. 2004 to Dec. 2007, a total of 23 ( 14 male and 9 female, aged between 30 and 72 years old) patients with pancreatic cancer in the ucinate process involving mesentery root were treated in our department. Curative resection was performed for all patients by the extended pancreaticoduodenectomy with superior mesenteric artery (SMA) isolation and mesentery root resection. The surgical procedure, the safety and prognosis were analyzed retrospectively. Results 12 patients underwent the procedure, among them 11 also underwent combined SMV partial resection and reconstruction. The operation time was (4.2 ± 1.1 ) hours, and the blood loss was ( 1 635 ± 1 362) ml with the blood transfusion of ( 1 609 ± 1 462 ) ml. There was no operation related death in this case series, and mild to severe diarrhea occurred in 6 cases. The post-operative stay ranged 9 to 30 days. The pathological examination showed that the tumor size was (5.3 ± 1.4) cm. 13 patients (57%) had one or more lymph nodes metastasis. 20 patients (87%) had nerve involvement. Among 11 patients with SMV partial resection and reconstruction, 10 patients had endangium involvement. 22 patients had negative surgical margins for all specimens. Rapid intra-operative frozen pathological examination showed negative surgical margins in one patient, however, post-operative paraffin section pathological examination revealed nerve involvement between SMA and celiac trunk. After a follow-up of 5 to 42 months, liver metastasis occurred in 4 patients, and local recurrence occurred in 3 patients. The 1-year and 2-year accumulated survival rates were 77.2% and 42.5%, respectively. Conclusions Isolation SMA and the mesentery resection in extended pancreaticodudenectomy were safe and useful. Using this modified technique, Radical operation resection could be achieved in the treatment of pancreatic cancer in uncinate process.

OBJECTIVETo investigate the emergency treatment for large amputated ear defect.

METHODSFrom Feb. 2010 to Oct. 2013, 5 cases with large unilateral amputated ear defects were treated. The amputated auricular cartilage was replanted subcutaneously in mastoid area at the first stage. Cranioauricular sulcus was reconstructed and skin grafting was performed at the second stage.

RESULTSAll cases were followed up for 3-6 months with satisfactory result. The reconstructed helix, scapha and cavity of auricular concha had similar color and elasticity as the ear at healthy side. Scar at donor sites, such as inguinal region and armpit, was inconspicuous.

CONCLUSIONSThe method of auricular cartilage replantation is an effective way for emergency treatment of large amputated auricular defect with less morbidity at donor site.
