This paper introduces how TiO2 film was prepared on pure titanium by anodic oxidation. Surface morphology and composition of the oxide film were analyzed by SEM coupled with EDAX. The deposition ability of hydroxyapatite of the anodized titanium in simulated body fluid (SBF) at 37 degrees C was evaluated. The results indicated that the oxide film was rough and honeycomb holes, connecting with each other, could be found on the surface. The holes with the diameter of 1-2 microm were distributed uniformly, which was typical for anodic oxidation. After alkaline treatment, hydroxyapatite deposition on the oxidized specimens in SBF was improved significantly.

OBJECTIVE: To study the feature and treatment method of patients with empty sella merger cerebro-spinal fluid leakage of nasal. METHOD: There were 8 cases with empty sella merger cerebrospinal fluid leakage of nasal, 2 cases were accepted the repairing surgery of cerebrospinal fluid leakage one time, 4 cases were accepted the repairing surgery of cerebrospinal fluid leakage used endoscope 2 times, 1 case was accepted repairing surgery of cerebrospinal fluid leakage used endoscope merge craniotomy and ventricle celiac bypass, 1 case recurrences after repairing surgery of cerebrospinal fluid was recurred after conservative treatment. Some postoperative were stayed in bed for three weeks and lumbar drainage for 1 week. RESULT: One case of cerebral hemorrhage after surgery was cured with craniotomy, followed for 2 years without recurrence. One case was recurred after conservative treatment. Two cases recurrences after surgery 3 years ago were accepted surgery again followed by one year without recurrence. One case who recurrence 1 year later was accepted repairing surgery of cerebrospinal fluid leakage used endoscope merge craniotomy and ventricle celiac bypass followed six months without recurrence. One cash after once surgery was followed half a year without recurrence. One case with recurrence 5 years later was accepted repairing surgery again. CONCLUSION The patient with empty sella combined cerebrospinal fluid leakage of nasal was rare, the main method was endoscopic sinus surgery treatment, but it recurred usually. The patients with repeatedly recurrence can be considered to accepted the surgery of ventricle celiac bypass. It required long-term postoperative follow-up and review.

We coated a thin TiO2 film on the surface of Ni-Ti shape memory alloy by activated sputter method in the present work. The blood platelet adherence and antithrombogenicity of the TiO2-coated Ni-Ti alloy were evaluated. The results showed that the platelets on the TiO2-coated Ni-Ti alloy were fewer than those on 316L stainless steel, and no agglomeration or distortion for the platelets on the coated alloy was found, which means less probability of blood coagulation for the alloy. The coagulation time on the coated Ni-Ti shape memory alloy was longer than that on the 316L. Compared with that on the 316L stainless steel, the TiO2 coated Ni-Ti shape memory alloy showed better blood compatibility, indicating that the Ni-Ti alloy with TiO2 coating is a kind of ideal biomedical materials with high clinical value.

OBJECTIVETo explore the feature of primary light chain amyloidosis patients treated with high-dose melphalan with auto peripheral blood stem cell transplantation (auto-PBSCT) and bortezomib plus dexamethasone (VD).

METHODSThirty-eight patients diagnosed from September 2004 to September 2012 were analyzed retrospectively, including 15 cases received auto-PBSCT, 23 cases exposed with VD.

RESULTSThe median follow-up duration for the patients was 34 months (range, 1-112 months), including auto-PBSCT group of 38 months (range, 5-112 months) and VD group of 31 months (range, 1-108 months). The organ response rate in all the patients was 39.5% (15/38), and the organ response rate between these two groups has no significant difference [33.3% (5/15) vs 43.5% (10/23), P=0.532]. However, the median time of organ response was significant difference [6 (3-10) months vs 3 (1-6) months, respectively (P=0.032)]. The 3-year overall survival (OS) rates in the two groups were 72.0% and 66.9%, and their average survival were 84.7 months and 75.9 months, respectively (P=0.683). In the patients with auto-PBSCT, the occurrence of III-IV grade of bone marrow suppression (P<0.001), fever (P<0.001), nausea and infection (P=0.006) were obviously higher than those with VD, but there was no statistically significant difference in pulmonary infection (P=0.069) and bloodstream infection (P=0.059).

CONCLUSIONSThe preliminary results have presented that primary light chain amyloidosis patients treated with auto-PBSCT or VD had similar organ response rate and survival. However, more adverse events occurred in the group of auto-PBSCT.
