BACKGROUND:During artificial knee replacement for al kinds of severe knee disease or conservative treatment for end-stage knee disease, Deluxe-PS knee prosthesis and PFC Sigma RP knee prosthesis have their advantages.
OBJECTIVE: To compare and analyze the matching of the Deluxe-PS and PFC Sigma RP knee prostheses with bone cross section.
METHODS:According to the use of the knee prosthesis, 87 gonarthritis patients undergoing bilateral knee replacement were divided into two groups. 46 cases in the test group received Deluxe-PS knee prosthesis replacement. 41 cases in the control group received PFC Sigma RP knee prosthesis replacement. Operation time and intraoperative blood loss were compared between the two groups. American Knee Society score, knee score of American Special Surgical Hospital and knee joint range of motion were used to evaluate knee joint function before replacement, 3 months after replacement and during final folow-up. Anteroposterior X-ray films were obtained after replacement to measure valgus angle and flexion angle of femoral prosthesis.
RESULTS AND CONCLUSION: (1) Operation time and intraoperative blood loss were significantly better in the test group than in the control group (P< 0.05). (2) No significant difference in American Knee Society score, knee score of American Special Surgical Hospital and knee joint motion was detected between the two groups before replacement and 3 months after replacement (P > 0.05). Above indexes were significantly improved in both groups at 3 months after replacement and during final follow-up (P < 0.05). (3) No significant difference in valgus angle and flexion angle of femoral prosthesis was identified between test and control groups during final follow-up (P > 0.05). (4) These findings indicate that effect of Deluxe-PS type artificial knee prosthesis was identical to that of PFC Sigma RP knee prosthesis in knee osteoarthritis patients receiving bilateral knee joint replacement. Deluxe-PS type artificial knee prosthesis can perfectly realize high-accuracy combination of the prosthesis and the bone cross section, and enhance the fusion suitability of the prosthesis and the bone surface. Deluxe-PS type artificial knee prosthesis has the advantage of operation. This advantage is possibly because Deluxe-PS type artificial knee prosthesis is more in line with the anatomical structure of the knee joint of Chinese.

Objective To evaluate the effect of anterior minimally invasive plate osteosynthesis (MIPO) for treatment of middle humeral shaft fracture.Methods From November 2011 to March 2014,10 cases of middle humeral shaft fracture were treated using MIPO via the anterior approach (MIPO group).Another 26 cases treated by open reduction and internal fixation (ORIF) of the middle humeral shaft fracture between October 2010 and March 2014 were included as controls (ORIF group).Fracture fixation using the 4.5 mm locking compression plate (LCP) was performed in both groups.Parameter measurements included operative time,intraoperative fluoroscopy times,grafting rate,intraoperative blood loss,postoperative drainage,hospital stay,bone healing time and complications.Results MIPO and ORIF groups differed significantly with respect to intraoperative blood loss [(93.5 ± 25.6) ml vs (325.3 ± 158.3) ml],intraoperative fluoroscopy times [(13.2 ± 6.1) vs 4.0 (0-6.0)] and hospitalization [(11.9 ± 1.7)days vs (18.0 ±4.7)days] (P ＜0.05).Bone grafting and drainage were not performed in MIPO group,while bone grafting rate was 54％ and postoperative drainage volume was (120.4 ± 69.6) ml in ORIF group (P ＜0.05).MIPO and ORIF groups were comparable with respect to operative time [(79.0 ± 22.0) min vs (97.5 ± 30.8) min],bone healing time [(15.2 ± 2.5) weeks vs (18.2 ± 4.8)weeks] and postoperative complications (10％ vs23％) (P＞0.05).Conclusion Anterior MIPO is an effective procedure for treatment of middle humeral shaft fracture,with advantages of small trauma,less bleeding,low risk of nerve injury and high rate of fracture healing.

BACKGROUND: A novel biodegradable Mg-Zn alloy is designed which the density and the Young's modulus are proximal to human bone. At the same time, it depletes the toxicity of aluminium and rare earth element in commercial magnesium alloys. OBJECTIVE: To observe the effect of Mg-Zn alloy (Mg-6%Zn) on the integrin βi expression of preosteoblasts MC3T3-E1. DESIGN, TIME AND SETTING: A contrast study was performed at the Central Laboratory of the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University between March and May 2008. MATERIALS: The Mg-6% Zn was prepared by School of Materials Science and Engineering of Shanghai Jiao Tong University, which the density was 1.82 g/cm~3 and the Young's modulus was nearly 44 GPa. Poly-L-lactic acid (PLLA) was used as the controls. MC3T3-E1 cells were provided by Chinese Academy of Science Type Culture Collection. METHODS: The cell attachment was observed after cultured with Mg-Zn and PLLA at 2, 24 and 48 hours under scanning electron microscope; the integrin β1 mRNA expression of MC3T3-E1 cultured with Mg-Zn and PLLA was estimated by real-time fluorescent quantitative polymerase chain reaction (real-time PCR) at days 1, 3, 6, 9,12 and 15 after culture. MAIN OUTCOME MEASURES: The MC3T3-E1 cells attachment on the material surface and the integrin β1 mRNA expression. RESULTS: MC3T3-E1 cell adhesion was better on the Mg-Zn alloy surfaces than on the PLLA surface; The integrin (31 mRNA of osteoblasts on Mg-Zn kept on expressing during experiment and increased with time (P < 0.01), but there was no significantly difference between the two groups at the same time (P > 0.05). CONCLUSION: MC3T3-E1 cell adhesion is better on the Mg-Zn alloy surfaces than on the PLLA surface, but it is not mediated by inducing the integrin p1 mRNA expression.

Objective To screen for the potential protein biomarkers in serum for the diagnosis of idiopathic Parkinson's disease (PD) using proteomic fingerprint technology. Methods Proteomic fingerprint technology combining weak cation exchange (WCX) magnetic beads with MALDI-TOF-MS was used to identify and compare the serum proteins from 61 patients with idiopathic PD, 29 patients with other neurodegenerative diseases (OND) and 30 healthy blood donors. Model of biomarkers and proteomics patterns associated with PD was analyzed by Biomarker Patterns Software. The model also was validated by 40 newly recruited PD cases. Results A total of 17 discriminating M/Z peaks which were related to PD were identified ( nonparametric test, Z:-4.039--2.633, P<0.01 ). Five biomarkers with M/Z of 6121, 5234, 2961,4309 and 8170 respectively generated an excellent model of distinguishing between PD and healthy groups. The sensitivity was 98.4% and the specificity was 83.1%. Blind testing in 40 newly recruited cases demonstrated a sensitivity of 85.0% (17 of 20 PD) and a specificity of 70. 0% (14 of 20 controls). Conclusions Combination of WCX magnetic beads with MALDI-TOF-MS is a useful method in establishing proteomic patterns associated with PD. It also may be used to construct a diagnostic model with PD Biomarkers. Although this model of biomarkers fails to distinguish between PD and OND controls, it is able to differentiate PD from healthy controls.
