ABSTRACT
Objective To discuss the types, characteristics, and the evaluation of disability of knee injuries. Methods The data of 133 cases of knee injury from 2017 to 2019 were collected and statistically analyzed according to the region of injury, the degree of disability, etc. Results One hundred and twenty-five cases of injury were compound, and 8 cases were simple. The incidences of ligament injury, meniscus injury and fracture were 88.72%, 75.19% and 57.89%, respectively. Of the cruciate ligament injuries, 12 cases were posterior cruciate ligament injury while 51 cases were anterior cruciate ligament injury, and the differences between the two kinds of injury had statistical significance （P<0.05）; 32 cases were secondary traumatic arthritis. The rates of disability of knee injuries were 38.35% （Grade Ⅸ and Ⅹ）. Conclusion Compound knee injuries are common, and traumatic arthritis has a relatively high rate. Multiple injuries can affect the stability and weight-bearing of the knee joint. It is suggested that in addition to evaluating the range of motion of knee joint, multiple factors should be considered to assess disability.

Objective To analyze types, mechanism and forensic identification for traumatic visual loss. Methods 109 cases of the evaluation for impairment and disability on traumatic visual loss were retrospectively analyzed, including interocular differences, anisometropia, left or right eye and the distributions of visual acuity, etc. Results The male-to-female ratio was 5.8:1, mainly 30~59 years of age. The ratio of monocular versus binocular injuries was 17.17:1. The ratio of left versus right injured eye was 1.39:1 in intentional injury cases. 115 eyes were injured, 83 of which were in low vision or blindness. 95 patients(87.16%) had large interocular differences( ≥ 3 lines). There were 9 patients with anisometropia from 2.25D to 6.00D and 23 patients with anisometropia larger than 6.00D. Conclusion Interocular differences and anisometropia are common in practice, which are not included in the expertise standard yet. Functional vision should be considered when developing the expertise standard.
ABSTRACT
The paper introduces the research background of preparation and revision of Traditional Chinese Medicine (TCM) nursing management information standard,analyzes the difficulties in the process of preparation and revision of the standard,including the building of the nursing management information model,handling of problems of multi-source and interdisciplinary management information,embodiment of features of TCM and innovation of the current health information standard,and puts forward countermeasures to solve corresponding problems on this basis.
ABSTRACT
Objective To research the relationship between binocular acuity and monocular acuity,and their effect on the evaluation of visual impairment and disability. Methods 1006 patients, aged between 18 and 60 years, are measured monocular and binocular acuities after the best lens correction. Results Binocular vision is higher than, equal to and less than monocular vision, three accounted for 27.14%, 70.78% and 70.78% respectively. Interocular difference has certain correlation with binocular interactions (χ2=54.939,P<0.05,r=0.228). Thirty-three patients have same binocular acuity but different monocular acuity. Conclusion Binocular acuity associated with the monocular acuity and the better eye vision plays a special role in visual disability evaluation.
ABSTRACT
Nitric oxide (NO), which is involved in the regulation of the cardiovascular system, nervous system, immune system, reproductive system, digestive system and other physiological activities, is an important biological substance with activity. Under normal physiological conditions, neuronal nitric oxide synthase (nNOS) can precisely regulate the nervous system NO production, release, diffusion and inactivation processes. But an excess of NO associates with the development of cerebral ischemia, Alzheimer's and Parkinson's psychosis nervous system diseases, while inhibition of nNOS activity can regulate the content of NO in vivo, and produce a therapeutic effect on some of the nervous system diseases. This review mainly describes the structure and regulation of nNOS and recent developments of small molecule inhibitors of nNOS.
