Metal nanoparticles (NPs) may have the potential to overcome problems related to conventional chemotherapy. Metal NPs reported to play a beneficial and powerful role in cancer therapy providing better targeting, gene silencing and drug delivery. Functionalised metal NPs with targeting ligands offer a better control of energy deposition in the tumours. Apart from therapeutic benefits, metal NPs are also used as a diagnostic tool for the imaging of cancer cells. Metal NP-based therapeutic systems not only provide simultaneous diagnostic and therapy but also allow controlled and targeted drug release which helps to revolutionise cancer treatment and management. This review addresses the advancement of metal NPs in tumour therapy with a focus on those being explained into clinical settings. 相似文献

Background
Acetabular component positioning is crucial to a successful total hip arthroplasty (THA). This study evaluated the effect of absolute acetabular component position as well as acetabular position relative to bony anatomy on patient-reported functional outcomes after primary THA.Methods
Primary, press fit, hemispherical metal-on-polyethylene THA performed between 2003 and 2011 were analyzed. Western Ontario and McMaster Osteoarthritis Index (WOMAC), Harris Hip Score (HHS), Short Form-12 scores, and radiographs between 2 and 3 years after the index procedure were assessed.Results
Of the 1241 primary THA included, the mean abduction and anteversion angles were 44.4 ± 6.94 and 21.7 ± 11.9 degrees, respectively. The mean anterior and lateral overhang were 1.9 ± 3.6 and 2.5 ± 3.4 mm, respectively. There was no correlation between functional outcomes and acetabular inclination. A weak positive correlation between anteversion and HHS (P < .001) and WOMAC (P = .02) scores was found. For relative position, anterior overhang of the acetabular component beyond the bone resulted in inferior Short Form-12 physical function (P = .001), HHS (P = .004), and WOMAC (P < .001) scores compared to those with bony coverage. Mean HHS pain score was 41.20 ± 5.69 in patients with lateral overhang and 41.97 ± 5.04 in those who had bony coverage of the lateral edge of the acetabular component (P = .02).Conclusion
The tribology and biomechanics of acetabular component position have been extensively studied without examination of how it affects patient function. Although statistical significance was seen, clinical outcome scores were not sensitive enough to show a clinically significant effect of the absolute or relative position of the acetabular component. 相似文献993.

This paper discussed the injury mechanism and management of a patient who had concomitant ipsilateral hip and knee dislocations and contralateral open leg fracture.A 32-year-old man presented with ipsilateral fracturedislocations of the left hip (Pipkin's type Ⅳ) and knee (Moore Ⅱ)joints and contralateral open fracture of the leg bones after a car accident. After emergency resuscitative measures, the hip joint was reduced and Pipkin's fracture was fixed using Ganz approach with lag screws; knee joint was reduced closely and tibial plateau fracture was stabilized with lateral buttress plate and a transarticular spanning fixator. The open fracture on the other leg was debrided and fixed with an external fixator. There was no instability in both joints after fixation when he was examined under anesthesia. The fractures united after 3 months and the patient had no residual instability of hip and knee. There was no clinical or radiological evidence of osteonecrosis in the hip joint after 6 months. At one-year follow-up, he had satisfactory functional outcome with almost normal range of motion at both joints.Ipsilateral hip and knee dislocations are rare injuries and more caution is needed for early diagnosis. A timely appropriate intervention can provide good functional outcome to the patient in this situation. 相似文献

Pneumomediastinum and subcutaneous emphysema can occur due to various reasons but spontaneous occurrence is rare. This rare condition can occur due to a number of traumatic and non-traumatic causes. Neoplastic lesions causing pneumomediastinum are exceedingly rare. We present such a case in a child where mediastinal mass caused non-traumatic pneumomediastinum, pneumopericardium, subcutaneous and retroperitoneal emphysema. To the extent of our knowledge, this is the first reported case of mediastinal mass resulting in spontaneous air leak. 相似文献
