OBJECTIVEThis study aims to determine the effect of fluoride concentration on the corrosion behavior of cobalt-chromium alloy fabricated by two different technology processes in a simulated oral environment.

METHODSA total of 15 specimens were employed with selective laser melting (SLM) and another 15 for traditional casting (Cast) in cobalt-chromium alloy powders and blocks with the same material composition. The corrosion behavior of the specimens was studied by potentiodynamic polarization test under different oral environments with varying solubilities of fluorine (0, 0.05%, and 0.20% for each) in acid artificial saliva (pH = 5.0). The specimens were soaked in fluorine for 24 h, and the surface microstructure was observed under a field emission scanning electron microscope after immersing the specimens in the test solution at constant temperature.

RESULTSThe corrosion potential (Ecorr) value of the cobalt-chromium alloy cast decreased with increasing fluoride concentration in acidic artificial saliva. The Ecorr, Icorr, and Rp values of the cobalt-chromium alloy fabricated by two different technology processes changed significantly when the fluoride concentration was 0.20% (P < 0.05). The Ecorr, Icorr, and Rp values of the cobalt-chromium alloy fabricated by two different technology processes exhibited a statistically significant difference. The Icorr value of the cobalt-chromium alloy cast was higher than that in the SLM group cobalt-chromium alloy when the fluoride concentration was 0.20% (P < 0.05). The Ecorr, tRp alues of the cobalt-chromium alloy cast were lower htan those of the SLM group cobalt-chromium alloy when the fluoride concentration was 0.20% (P< 0 .05).

CONCLUSIONFluoride ions adversely affected the corrosion resistance of the cobalt-chromium alloy fabricated by two different technology processes. The corrosion resistance of the cobalt-chromium alloy cast was worse than that of the SLM group cobalt-chromium alloy when the fluoride concentration was 0.20%.

Objective To study the effects of sodium bicarbonate (SB) on resuscitation in swine model of asphyxiation cardiac arrest (CA).Methods Thirty-two healthy miniature pigs were randomized (ramdom number) into two groups,the SB group (n =16) and the control group (n =16).Animals in both groups underwent endotracheal tube clamping to induce CA.Once induced,CA left untreated for a period of 8 minutes.At the beginning of initiation of cardiopulmonary resuscitation (CPR),SB (1.0 mEq/kg,diluted to 40 mL) was injected in central venous in SB group and isopyknic normal saline solution was injected in control group.Two minutes following initiation of CPR,defibrillation was attempted until return of spontaneous circulation (ROSC) was achieved or animals died.To assess the SB effects on myocardial metabolism,positron emission tomography (PET) was performed at baseline and 6 after ROSC.To analyze 18F-FDG myocardial uptake identified in PET,the maximum standardized uptake value (SUV) was measured.Results ROSC was 10/16 successful in SB group and only 8/16 successful in control group.The average survival time of SB group was (3.63 ± 0.76) h and that of control group was (2.45 0.70) h.Myocardial metabolism imaging using PET demonstrated that myocardial metabolism injuries in control group were more severe than in SB group at 6 h after ROSC and SUVmax was more higher in SB group than in control group (6 hrs after ROSC:1.32 ± 0.20 vs.1.10 ± 0.14,P =0.035).Conclusions In swine model of asphyxiation CA,SB improve the myocardial metabolism and might raise the possibility of ROSC and have no hypernatronemia.

OBJECTIVE: To observe the changes of peristalsis of small intestine in guinea pigs after administration of traditional Chinese medicines activating blood to resolve stasis (Compound Danshen Decoction, CDSD) or/and medicines dredging intestines (Dachengqi Decoction, DCQD), and to explore the synergetic or intensive effect of CDSD on DCQD. METHODS: By means of BL-420 Biological Experimental System, peristalsis of small intestine was recorded and analyzed following administration of DCQD, CDSD or Huoxue Chengqi Decoction (HXCQD, compound of CDSD and DCQD) respectively in different experimental periods. RESULTS: The amplitude and frequency of intestinal peristaltic wave obviously increased following administration of the three decoctions, but HXCQD appeared to be most dominantly. CONCLUSION: The effect of DCQD can be further enhanced by combining use of CDSD, suggesting that the traditional Chinese medicines activating blood to resolve stasis have an intensive effect on medicines dredging intestines.

Objective To evaluate the value of intraduetal ultrasonography (IDUS) in diagnosing biliary and pancreatic disorders. Methods The findings by endoscopic retrograde cholangiopancreatography (ERCP) and IDUS from 19 patients with suspected biliary and pancreatic disorders from July 2006 to August 2007 in our hospital were analyzed retrospectively. Results Of the 19 patients, 17 had obstructive jaundice (including 6 eases of cholangiocarcinoma, 2 pancreatic adenocareinoma, 2 gallbladder carcinoma, 2 chole-docholithiasis with bile duct stricture, 2 autoimmune pancreatitis, 1 papillary adenocarcinoma, 1 papillary adenoma, and 1 sclerosing cholangitis) and 2 intraduetal papillary mueinous tumor (IPMT). The diagnosis was confirmed by surgery and pathological findings in 11 patients. The diagnostic accuracy of ERCP and IDUS was 73. 7% (14/19) and 84. 2% (16/19), respectively, and that of ERCP combined with IDUS was 89. 5% (17/19). The sensitivity and specificity of ERCP to differentiate benign bile duct strictures from ma-lignant ones were 100. 0% (11/11) and 83.3% (5/6), respectively; and those of IDUS were 100. 0%(11/11) and 100. 0% (6/6), respectively. The sensitivity and specificity of ERCP in diagnosing cholan-gioeareinoma were 83.3% (5/6) and 60% (3/5), respectively; and those of IDUS were 100. 0% (6/6) and 40. 0% (2/5), respectively. Conclusion Combination of ERCP with IDUS can improve the diagnostic accuracy of pancreaticobiliary disorders. Additionally, IDUS shows higher sensitivity and specificity in differ-entiation between benign and malignant bile duct strictures, but it is still difficult to identify the etiologic factors of malignant bile duet strictures by IDUS.

Objective To evaluate the efficacy and safety of alemtuzumab in renal transplant recipients treated with induction therapy. Methods Eighty-nine cadaveric renal transplant recipients in our department were randomly divided into experimental group (n = 43) treated with alemtuzumab induction, 15 mg i. v. and control group (n = 46). Main immunosuppressive therapy regimen consisted of steroids, tacrolimus or cyclosporine and mycophenolate mofetil in all recipients. Post-transplant kidney function, acute rejection,infection, DGF, graft survival, lymphocyte counts were recorded within 1 year. ATP values in CD4+ T cells after transplantation was determined by using Cylex ImmuKnow assay. Results There was significant difference in the incidence of biopsy-proven acute rejection, but no significant difference was found in ImmuKnow ATP values during 6 months after transplantation and lymphocyte counts during 3 months, graft survival and the incidence of infections between the two groups. Conclusion Induction therapy with alemtuzumab appeared to be effective in the prevention of acute rejection.

Objective To evaluate the effect of pronator teres tendon reconstructing the forearm interosseous membrane(IOM)central band on restoring the longitudinal stability of the forearm after Essex-Lopresti injury.Methods A total of ten fresh-frozen adult cadaveric forearms were loaded axially through the humeral and the distal radius.Each forearm was tested as following six steps:radial head excision,radial head plus excision of triangular fibrocartilage complex(TFCC),radial head plus TFCC plus excision of IOM central band,reconstructing central band with pronator teres tendon,metallic radial head prosthesis replacement,central band reconstruction plus radial head prosthesis replacement.The difference of the load exerted to displace the radius to the proximal for 5 mm was compared at different steps by using single-factor analysis of variance.Then,the effect of each step on restoring the forearm longitudinal stability of the forearmwas evaluated.Results There was statistical difference upon load for the radial displacement to the proximal for 5 mm in all six steps,ie,(74.51±15.17)N,(49.23±6.14)N,(17.83±4.73)N,(27.40±3.56)N,(140.25±25.39)Nand(164.21±28.26)N,respectively(P＜0.01).With migration of the radius to proximal for 5 mm,the load for pronator teres reconstruction was 55.66% of radial head plus TFCC,and the load for pronator teres reconstruction plus radial head prosthesis replacement was 559.31% of IOM reconstruction step and 333.56% of radial head excision.Conclusions Reconstruction of the central band with pronator teres tendon is insufficient to restore the longitudinal stability of the forearm after Essex-Lopresti injury.Reconstruction of the central band in combination with metallic radial head prosthesis replacement are beneficial to restoring the longitudinal stability of the forearm.
