Study on application of posterior tibial slope angle in anterior cruciate ligament / 中国骨伤

Posterior tibial slope angle (PTSA) is a risk factor for anterior cruciate ligament (ACL) injury and has attracted a lot of attention, but its mechanism of action and diagnosis are still not systematically studied in the field of sports medicine. In this paper, we believe that PTSA should be measured by full-length lower extremity films and combined with multiple imaging data for comprehensive assessment to reduce errors. A large PTSA may increases risk of anterior cruciate ligament injury, so patients with more than 12 degrees of PTSA should be treated by preserving meniscus as much as possible during ACL reconstruction and combining with tibial osteotomy if necessary, which could effectively prevent risk of ligament re-injury. At the same time, gait analysis has an important reference value for preoperative pathogenic pattern and postoperative rehabilitation function, so the author believes that it will have a guiding significance for the development of individualized rehabilitation strategy based on PTSA, in order to achieve the best treatment effect.

Refurbishment of Environmental Damage and Socio-Economic Consciousness Relate to Improvement of Climate Change

Demand for energy, water, food and shelter for raising the standard of lifestyle of country people is the driving force of democracy in modern days but that cause the environmental damages through Green House Gas, micro-particles emission from combustion of fossil fuels like coal, oil as well as fuel gases and incessant emissions of hydrocarbons from automobiles, oil fields, oil refineries besides industrial activities in the globe along with horizontal land encroachment decreasing greeneries in the planet earth with the decrease of oxygen/nitrogen ratio. The emissions are the main causes for increase in environmental pollution and responsible for climate change in contrast to the idea expressed by various researchers about the impact of climate change on environment. Mechanisms on interaction of solar/electro- magnetic radiation with PM1-2.5 and hydrocarbons in air play a role on degradation of stratospheric ozone as well as accumulation of ozone in troposphere which manifests in various episodes and global warming. Increasing population, increasing urbanization with growing carbon footprint, deceasing greeneries in the planet, the carbon-dioxide: oxygen: Nitrogen ratios in the atmosphere suffered for the last 1000 years or more. The initiatives that are needed to promote the environmental capacity through replacement of fossil fuel energy by green energy establishments, socital up-liftment through intercontinental sweet relations instead of power supremacy depriving 80% global population to refurbish the health of environment with improvement of climate. The fruit of green energy to reach all classes of people in this earth is the immediate need of the globe. The flaws of environmental laws are to be tightened and socio-environmental economic culture is to be inculcated among citizens of states for environmental health improvement vis-a-vis control on climate change to save the planet from extinction of dominant human lives.
