Objective To explore the effect of combined application of improved microencapsulation and intravenous injection of donor liver cells and spleen cells on pancreatic islet xenografts. Methods New born male pigs and SD rats were selected as donors and recipients respectively, and pig pancreatic islet cells were microencapsulated by static electricity improvement microencapsulation. Islet transplantation was performed after injection of donor liver cells and spleen cells via tail vein. The changes in blood glucose and serum C-peptide, the function-possessed days of islet xenografts and diabetes rats living period were observed. Results In combined application group, the function-possessed days of islet xenografts and diabetes rats living period were significantly prolonged (P

Objective To evaluate the significance of intraoperative laparoscopic ultrasonography (IOUS) during hepatobiliary surgery. Methods Sixty-eight cases of hepatobiliary lithiasis (liver disease 23 and cholecystopathy with difficulty in management by preoperative estimation, 45 ) were examined by intraoperative laparoscopic ultrasonography. Results Two CBD stones and one Mirrizi syndrome were found in IOUS. The laparoscopic procedures were successful fulfilled in 68 cases under the guidance of sonography including fenestration on liver cyst, incision and drainage on liver abscess, resection and biopsy on space occupied liver lesion with unknown cause, resection of solitary space occupied mass in liver, destruction of unre-sectable liver cancer by microwave and injection of absolute alcohol and chemotherapy through portal vein catheterization, cholecystectomy in acute cholecystitis, chronic cholecystitis with chiledolithiasis, and broad pedicle polyps in gallbladder etc. Conclusion IOUS has the advantages of non-invasive, fast, repeatable, high accuracy and has important clinical significance in laparoscopic diagnosis and treatment.

Objective The aim of this study was to determine the effects of ulinastatin, a broad spectrum proteinase inhibitor, on fibrinolytic system and platelet function during open heart surgery performed with cardiopulmonary bypass (CPB) .Methods Twenty ASA Ⅰ-Ⅱpatients of both sexes undergoing cardiac surgery under CPB were randomly divided into two groups of ten patients: control group(C) and ulinastatin group (U). In group U patients received ulinastatin 12 000 U?2kg-1 . Half of the dose was given iv 10 min before CPB and the other half was added to the priming solution. In group C patients received normal saline instead of ulinastatin. Blood samples were taken before CPB (T1 ) , 30 min after CPB was started (T2), at the end of CPB (T3), 2 h and 4 h after CPB(T4 , T5) for determination of plasma levels of D-Dimer, ?-granule membrane protein-140 (GMP-140), thromboxane B2 (TXB2) and 6-Keto-prostaglandin F1? (6-Keto-PGF1?) .Results The demographic data, aortic cross-clamping time, CPB time and duration of operation were comparable between the two groups. The plasma levels of D-Dimer, GMP-140, TXB2 and TXB2/6-Keto-PGFl? were significantly increased at T2 , T3 and T4 as compared with the baseline (T1 ) in both groups, but the increase was significantly larger in group C than in group U(P

Objective To evaluate the feasibility,safety,and cosmetic results of single-incision laparoscopic appendectomy by using conventional instruments. Methods From January 2013 to May 2014,clinical data of 52 patients undergoing single-incision laparoscopic appendectomy in our hospital were retrospectively analyzed. The appendectomy was performed by using conventional instruments through three 5-mm trocars via a 2-cm curved incision above the umbilical margin. Results The single-incision laparoscopic appendectomy was successfully completed in all the 52 cases without conversion to conventional laparoscopic or open surgery.The mean operative time was 43 ±7 min (range,30 -90 min).The average postoperative hospital stay was 2.5 ±0.5 days (range,1 -7 days).During follow-up visits for 1 -3 months,there were no postoperative complications.The scars were not obvious in all the patients. Conclusion Laparoscopic appendectomy can be achieved through a single incision by using conventional instruments.This approach is feasible,safe,and concealing.

Circulating tumor cells (CTCs) are present in the peripheral blood,and play an important role in the recurrence and metastasis of lung cancer.As the researches about CTCs and targeted therapy move along,it is found that CTCs can be used as a liquid tumor tissue to guide clinical treatment and have a certain significance in the clinical staging and prognosis evaluation of lung cancer.

Objective To report the integrated progress of the hydatid disease information management system,and to pro-vide the reference for further system improvements by analysis of results on simulation test feedback. Methods The work of in-stitutional code matching by collecting fundamental and integrated information of the system in epidemic areas of hydatid disease was carried out,and professional control agencies were selected to carry out the simulation test. Results The results of agen-cies code matching at stage indicated the average completion rate was 94.30% on administrative agencies,69.94% on registered professional agencies and 56.40% on professional institutions matching related to hydatid disease prevention and control imple-ments in seven provinces(autonomous regions)and Xinjiang Production and Construction Corps. Meanwhile,the response rate of open-ended proposals was 93.33% on fifteen feedbacks,and the statistics showed 21.43% believed the system was low fluen-cy,64.29% considered the system was inconvenience for data inputs and 42.86% considered it would be improved on system sta-tistics functions,of which 27.78% were provincial users,22.22% were the city users and 50.00% were the county users. Con-clusion The hydatid disease prevention information management system meets the fundamental needs of the majority agencies in hyperendemic areas of echinococcosis,it needs to develop the further test with more agencies joining after the work of the in-stitutional code matching completion and the system service improvement in the next stage.

A total of 96 patients with Graves'disease(GD)were followed for one and half years to observe the effect of antithyroid drugs(ATD)treatment.Serum TRAb,total iodine concentration and CD80 mRNA expression of peripheral blood monouclear ceils were measured.Logistics regression analysis was conducted with the combination of above parameters.Those GD patients with high level of TRAb,positive family history of GD, increased expression of CD80 and early age of onset were more inclined to relapse after ATD treatment.

Objective To explore the value of magnetic resonance perfusion imaging of 3D arterial spin labeling(3D-ASL)in the diagnosis of transient ischemic attack(TIA).Methods 78 of patients were diagnosed TIA on MR routine scan [T1 WI,T2 WI,T2-FLAIR,diffusion weighted imaging(DWI)],magnetic resonance angiography(MRA)and 3D arterial spin labeling(3D-ASL).The re-sult were analyzed by Chi-square test.Results In 78 patients,the abnormal routine scan was 0 case(0%);abnormal MRA 41 cases (52.6%);abnormal 3D-ASL 47 cases(60.2%);combination with each other were 60 cases(76.9%).29 cases with artery stenosis and abnormal ASL,12 case with artery stenosis and normal ASL,19 cases with normal vascular and abnormal ASL,18 cases with normal vascular and normal ASL.Conclusion 3D-ASL is better than routine magnetic resonance sequences in the diagnosis of TIA,which is convenient and should be a routine scanning sequence of TIA.3D-ASL,MRA and DWI have their own advantages and disadvantages, combination use can improve the diagnosis accuracy of TIA.

Objective To study the expression of urokinase-type plasminogen activator (uPA) and its relation with expression of receptor (urokinase-type plasminogen activator receptor uPAR) in epithelial ovari- an cancer (OEC) and with the clinic prognosis.Methods Expression of uPA and uPAR protein was detected by Streptavidin-biotin-HRP in 68 cases of epithelial ovarian cancer and compared with that in 10 cases of borderline tumor,10 cases of benign tumor and 10 cases of normal tissue,and correlation between them was analyzed.The different expression groups of uPA was correlated with the prognosis of ovarian epithelial can- cer.The expression of uPA showed a correlation with short survival time (P
