To improve the efficiency of halophilic actinobacteria screening and carry out the rapid selection of targeted strains, we tested 34 strains of Streptomonospora by PCR-single strand conformation polymorphism analysis (PCR-SSCP) based on genus-specific primers for the PCR identification. This approach employs PCR with two pairs of primers located in the 16S rRNA sequence flanking two variable region, then build clustering tree according as SSCP data. Synchronously, we sequenced all the 16S rRNA partial sequences for these strains to verify them. The results showed that the PCR-SSCP analysis was an efficient, easy-to-handle and economic method for rapid selection of halophilic actinobacteria resources.

Objective To retrospectively analyze the outcomes and adverse effects of sequential therapy of BTD and MPT regimen for the newly-diagnosed multiple myeloma patients no eligible for high dose chemotherapy and stem cell transplantation. Methods Thirty-six patients were involved in this study and the patients were treated with tandem therapy of BTD and MPT regimen. The patients were treated with BTD regimen as induced therapy no less than 2 cycles. When the patients got PR or above PR,they were treated with MPT regimen as consolidation therapy which was no less than 2 cycles. Then,the patients who achieved PR or partial PR were received MPT chemotherapy regimen as consequent treatment. After that,low dose thalidomide was used as maintenance therapy. The outcomes and adverse effects were retrospectively evaluated. Results Thirty-six patients were treated with BTD regimen as induced therapy. The results were that 7 patients (19.4 %) achieved CR,8 (22.2 %) VGPR,14 (38.9 %) PR and the OR rate was 80.6 %. The patients (n=29) who achieved no less than PR was treated with MPT regimen as consequent therapy. The results were that four patients were in progression and the others were stable. Twenty-five patients were treated with low dose thalidomide as maintenance therapy. The median progression-free survival (PFS) did not reached yet until last follow-up (median follow-up time was 16.5 months). One-year overall survival rate was expected 86.0 % and 3-year expected overall survival rate was 77.0 %. The main regimen-associated toxicities included thrombocytopenia,peripheral neuropathy (PN),Herpes Zoster,gastrointestinal symptoms,anemia,neutropenia,constipation,fatigue,rash and so on. The incidence of grade 3 and 4 adverse events was low. Conclusion Sequential therapy of BTD and MPT regimen can be used as the front-line therapy for the newly-diagnosed multiple myeloma patients no eligible for high dose chemotherapy and stem cell transplantation.

OBJECTIVETo improve the effect of operative management of acetabular fractures.
METHODSOne hundred and seventy eight acetabular fractures were treated operatively from August 1993 to December 2000. Their functional results and complications were analyzed.
RESULTSOne hundred and twelve hips were followed up for an average of 45.7 months. Heterotopic ossification was noted in 26 hips, post-operative osteoarthritis in 22 hips, avascular necrosis of the femoral head in 8 hips, and sciatic nerve injury in 7 hips after operations. No death and infection were found in this series.
CONCLUSIONSEctopic bone formation develops at extended ilio-femoral and Kocher-Langeneck approaches. Cartilaginous injury of the femoral head is contributable to post-operative osteoarthritis, and imperfect reduction is an important factor in the genesis of osteoarthritis.

OBJECTIVETo understand the diagnosis and treatment of marginal impaction of acetabular fractures.
METHODEighteen of 26 patients with marginal impaction of acetabular fractures were retrospectively reviewed. Marginal impactions was confirmed in 15 patients by CT scan before operation, and in 3 during operation. All patients were treated by ORIF, and the impacted bones were elevated with bone grafts (Bone graft was not used in one patient). All fractures were fixed with a reconstruction plate.
RESULTSThe mean follow up was 36.7 months (5 - 71 months). The modified D'Aubingne and Postel score system showed excellent results in 6 patients, good 7, fair 2, and poor 3.
CONCLUSIONPosterior fractures and dislocations of acetabular fractures are easily combined with marginal impaction, and can diagnosed by CT scan. Cortical impaction should be recognized as a special type. The impacted bone should be elevated for bone grafting.

OBJECTIVETo study the clinical significance of computed tomography (CT) in diagnosis and treatment of acetabular fractures.
METHODSThe plain and CT films of the 66 cases of acetabular fracture from January 2001 to June 2002 were analyzed retrospectively, and the radiological characteristics and results were compared to each other.
RESULTSThe diagnosis of 6 cases were changed after CT examination, and the occurrence ratio of marginal impaction, free body in joint, femoral head fracture, sacro-iliac injury and ischial tubersoity fracture involvement were 3:17, 7:29, 6:15, 0:5 and 1:5 in plain and CT examination respectively.
CONCLUSIONSCT examination has the determinative role in detecting weight-bearing zone, marginal impaction, free body, femoral head fracture, sacro-iliac injury, etc., and for completing the diagnosis and guiding the treatment. It should be the routine examination just as the three standard plain examinations in acetabular fractures, and should be carefully read.
