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%.

OBJECTIVETo explore the clinical effects of minor bone anchors and palmaris longus tendon graft in treating chronic mallet fingers deformity.

METHODSFrom January 2008 to June 2013, 26 patients with chronic mallet fingers deformity were treated with minor bone anchors and palmaris longus tendon graft. There were 18 males and 8 females, aged from 18 to 52 years old with an average of (32.0±1.3) years. Among them, 8 cases caused by machine injury, 6 cases by fall injury, 6 cases by sprain from fight, 4 cases by tendon spontaneous rupture, 2 cases by knife trauma. There was no tendon attachment of extensor tendon check in 16 cases, and with 0.3 to 0.5 cm tendon attachment in 10 cases. All patients had the flexion deformity and the disability of dorsiflexion activity. During operation, the distal interphalangeal joint was fixed in 10° to 20° dorsiflexion by a Kirshner wire, the minor bone anchor was used to reconstruct the extensor tendon insertion, the palmaris longus tendon slice was transplanted the decayed area of extensor tendon insertion. Four weeks postoperatively, the Kirshner wire was removed and the plaster external fixation was used, and the patient began function exercises. Postoperative complications were observed and fingers functions were assessed according to Dargan standard.

RESULTSThe patients were followed up from 6 to 14 months with an average of (5.0±0.3) months. Wound superficial infection occurred in 2 cases, the skin pressure ulcer in 2 cases, joint activities disability in 1 case; these symptoms got improvement after symptomatic treatment. Traumatic arthritis occurred in 2 cases, 1 case was improved after treatment, and 1 case had chronic pain for a long time. No internal fixation loosening or breakage and tendon rupture were found. According to Dargan standard to evaluate the finger function, 17 cases got excellent results, 8 good, and 1 poor.

CONCLUSIONIt is an effective way to treat the chronic mallet finger deformity using minor bone anchors and palmaris longus tendon graft, and the method has advantages of reliable fixation, easy operation, satisfactory effect and less complication.

Objective To discuss the intensive gastric cavitary lavage method in treatment of stress ulcer bleeding(SUB).Methods The therapeutic effects of 100 patients with severe SUB in intensive care unit (ICU)from July 2005 to February 2008 treated with intensive gastric cavity lavage method were observed and analyzed.Results In these 100 cases,the bleeding was stopped successfully in 97 cases,the therapeutic effective rate being 97%;there were 17 cases died of complicated pulmonary infection(17%)and 3 cases of bleeding(3%),the total fatality rate being 20%.All the other cases were cured.Conclusion Intensive gastrointestinal lavage therapy is an effective method as acid inhibitor for treatment of SUB,but it can decrease the inhabitant flora in the stomach to pass through gastric-pulmonary route,thus the incidence of pulmonary infection was reduced.

BACKGROUND: The number of living renal donation has increased in China and abroad, thus, it is important to guarantee the safety of donors. How to accurately diagnose potential renal disease and provide guidance plays an import role in protecting safety of living renal donors.OBJECTIVE: To establish an evaluation method for analyzing the correlation between histological abnormalities and clinical predonation parameters.METHODS: The related data on renal transplantation of Fuzhou general Hospital of Nanjing Military Area Command of Chinese PLA were retrospectively reviewed. Paracentesis were performed when the vessels of kidney were mutilated and perfusions were finished. Time-zero renal biopsy was evaluated for following pathological changes: interstitial fibrosis, tubularatrophy, arteriolar hyalinosis, mesangial proliferation, and glomerulosclerosis. Predonation data were demography, body weight, body mass index' systolic/diastolic blood pressure, serum creatinine, glomerular filtration rate, and proteinuria.RESULTS AND CONCLUSION: There were no signs of kidney disease in preoperative examination of all the 62 patients, time-zero renal biopsy found there were 28 donors with histological changes, interstitial fibrosis with age and serum creatinine, tubularatrophy with diastolic blood pressure and protein excretion rate, arteriolar hyalinosis with serum creatinine and glomerular filtration rate, mesangial proliferation only with body mass index, and finally the presence of glomerulosclerosis did not correlate with any variable.

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.
