Metal sulfides are chemically attacked by Fe~ 3+ and H~+, resulting in the formation of elemental sulfur via polysulfides or thiosulfate pathway. Elemental sulfur may aggregate and even form a layer on the metal sulfide surface, which will inhibit leaching metals from the sulfides minerals. Elimination of inert elemental sulfur in a typical acidic environment can exclusively be by way of oxidation of acidophilic sulfur-oxidizing bacteria, such a way includes the attachment, transport and oxidation process of elemental sulfur by acidophilic sulfur-oxidizing bacteria. On the basis of analysis on the pertinent researches, the molecular mechanism of sulfur elimination by the acidophilic bacteria is far away from elucidated, and to attain that target, there are still much work to be done for elucidating the molecular mechanism on the attachment, transport and oxidation process of elemental sulfur by the acidophilic sulfur-oxidizing bacteria.

The key point of study on CO2 removal by microalgae cultured in a photobioreactor is to improve CO2 removal capability. In this paper, a model of air-lift photobioreactor was developed by combination of conditions including the velocity of flow, the degree of mixing, the gas-liquid mass transfer and the rate of photosynthesis, and two corresponding simplified methods, such as time discretization and lumped parameters were put forward. Using a method of lumped parameters, the model for simulation of time course of DO, pH in the column air-lift photobioreactor and prediction of CO2, O2 concentrations in the outlet gas under different CO2 concentration in the aeration gas was thoroughly discussed. Experimental data were also used to verify the model which could potentially be applied to rational design of the photobioreactor, high-density culture of microalgae and efficient removal of CO2.

OBJECTIVETo evaluate middle and long-term results of total hip arthroplasties (THA) for the treatment of secondary hip traumatic osteoarthritis and femoral head necrosis after acetabular fractures.
METHODSFrom January 2000 to December 2005, 33 patients with secondary hip traumatic osteoarthritis and (or) femoral head necrosis after acetabular fractures were treated with THA. There were 21 males and 12 females, ranging in age from 27 to 69 years old, with an average of 52 years old. Twenty-three patients were performed with open reduction and internal fixation: 5 patients were treated with anterior approach; 12 patients, posterior approach; 6 patients, combined approaches; other 10 patients, conservative treatment in the early stage. All THA were performed with posterior-lateral approach. Bone union was achieved in the all acetabular fractures. Removal of all implants was necessary in 5 patients, and partial removal in 3 patients. Cemented cup was implanted in 6 patients and uncommented cup in 27 patients. Intraoperative and postoperative complications were observed, and Harris hip scores before surgery and 10 years after operation were compared. The prosthetic loosening, osteolysis or revision were used to evaluate 10 years survival rate of prosthesis.
RESULTSAll the patients were followed up,and the duration ranged from 10 to 15 years, with a mean of 12 years. One patient died at the 10th year after operation. The Harris score at the 10th year was higher than the preoperative one. One and two patients were performed with revision total hip arthroplasty caused by aseptic loosening alone and aseptic loosening combined with osteolysis respectively. Osteolysis occurred in 1 patient; deep venous thrombosis in 4 patients; dislocation of prosthesis in 2 patients. One patient had infection of incision and one patient had infection around the prosthesis. Ten years survival rate of implant was 84.8% (28/133).
CONCLUSIONTHA is an effective method to treat secondary hip traumatic osteoarthritis and (or) femoral head necrosis after acetabular fractures in improving hip joint functions with high implant survival rate and good middle and long-term results.
