Advances in the treament of talus fracture and its complications / 中国综合临床

Talus fracture is a relatively rare injury. The indication of surgical treatment of talus fracture is the obvious displacement of talus neck or talus body fracture, the purpose of which is to achieve anatomical reduction of the fracture site. The anatomical structure of talus is special, most of its surface is covered by the articular surface, so the injury often involves the articular surface, so the treatment is difficult and the incidence of complications after fracture operation is high, which is prone to ischemic necrosis and traumatic arthritis. Based on the anatomical structure of talus, we reviewed the latest treatment methods of talus fracture and its complications, the advantages and disadvantages of different treatment methods and the existing problems.

Comparison of differential proteomics between neural stem cells and motor neurons in embryonic spinal cord in rats / 解剖学报

Objective To analysis and compare the proteomic differences between neural stem cells and motor neurons in embryonic spinal cord in rat and discover the key different proteins. Methods Separating the protein of cells by the 2-D fluorescence difference gel electrophoresis, and to analyse the differences of protein expression with DeCyder software, and to identify with high performance liquid chromatography-electrospray tandem mass spectrometry. Results About 1 300 protein spots from the cells were gained after gel analysis. Eighty-seven protein spots were selected for mass spectrometry analysis. Fourty-four differently expressed proteins (24 in neural stem cells and 20 in motor neurons) were identified by mass spectrometry analysis.Conclusion Differently expressed proteins between neural stem cells and motor neurons were identified and it is helpful to find the new targets in neural stem cells differentiation into motor neurons.

Long-term ventilatory adaptation and ventilatory response to hypoxia in plateau pika (Ochotona curzoniae): role of nNOS and dopamine.

We assessed ventilatory patterns and ventilatory responses to hypoxia (HVR) in high-altitude (HA) plateau pikas, repetitively exposed to hypoxic burrows, and control rats. We evaluated the role of neuronal nitric oxide synthase (nNOS) and dopamine by using S-methyl-l-thiocitrulline (SMTC) inhibitor and haloperidol antagonist, respectively. Ventilation (Vi) was measured using a whole body plethysmograph in conscious pikas (n = 9) and low-altitude (LA) rats (n = 7) at different Pi(O(2)) (56, 80, 111, 150, and 186 mmHg) and in HA acclimatized rats (n = 9, 8 days at 4,600 m) at two different Pi(O(2)) (56 and 80 mmHg). The effects of NaCl, SMTC, and haloperidol on ventilatory patterns were assessed in pikas at Pi(O(2)) = 56 and 80 mmHg. We observed a main species effect with larger Vi, tidal volume (VT), inspiratory time/total time (T(i)/T(tot)), and a lower expiratory time in pikas than in LA rats. Pikas had also a larger VT and lower respiratory frequency compared with HA rats in hypoxia. HVR of pikas and rats were not statistically different. In pikas, SMTC induced a significant increase in Vi and VT for a Pi(O(2)) of 56 mmHg, but had no effect for a PiO(2) of 80 mmHg, i.e., the living altitude of pikas. In pikas, haloperidol injection had no effect on any ventilatory parameter. Long-term ventilatory adaptation in pikas is mainly due to an improvement in respiratory pattern (VT and T(i)/T(tot)) with no significant improvement in HVR. The sensitivity to severe acute hypoxia in pikas seems to be regulated by a peripheral nNOS mechanism.

Treatment for necrosis of the femoral bead by vascular bundle grafting / 中华显微外科杂志

entrate graft can block pathologic process and improve the inclusion of femoral head and increase blood circulation of femoral head, which is beneficial to its recovery.
