ABSTRACT
In clinical work, many chronic prostatitis whose main clinical manifestations of sexual neurasthenia are misdiagnosed due to lack of typical lower urinary tract symptoms and pelvic floor pain. Therefore, attention is paid to prostate digital rectal examination and routine examination of prostatic fluid, and neuromodulators or psychotropic medicine should not be applied in the performance of sexual neurasthenia alone. Instead, integrated traditional Chinese and Western medicine treatment measures should be actively adopted to achieve satisfactory clinical results.
ABSTRACT
BACKGROUND: There are many studies on Modic changes in patients with lumbar degenerative disease and low back pain. However, few studies facus on epidemiological distribution and related factors of Modic changes in cervical spine, and its epidemiology and influencing factors remain unclear.OBJECTIVE: To study the morbidity and distribution of Modic changes in patients with cervical and shoulder pain and its correlation with gender, age and cervical degeneration. METHODS: Totally 430 patients admitted in the Second Affiliated Hospital of Inner Mongolia Medical University and undergoing cervical MRI and CT examination due to neck and shoulder pain between December 2014 and December 2016 were retrospectively analyzed, involving 197 males and 233 females, aged 19-78 years (mean age: 50.3 years). The morbidity and segmental distribution of Modic changes and its correlation with age, sex, cervical intervertebral disc degeneration and facet joint degeneration were analyzed. RESULTS AND CONCLUSION: (1) Among 2 150 disc segments of 430 patients, 348 segments (16.2%) of 67 patients (15.6%) appeared with Modic changes:73(3.4%)segments were type I,243(11.3%)were type II,and 32(1.5%)were type III.(2)By application of chi-square test, Modic changes were most common at the C5/6segment; older than 40 years and Pfirrmann disc degeneration grade III were relevant factors, while gender and facet joint degeneration were not.
ABSTRACT
Disparity in the root morphology of six rice (Oryza sativa L.) genotypes varying in potassium (K) efficiency was studied with three K levels: 5 mg/L (low), 10 mg/L (moderate) and 40 mg/L (adequate) in hydroponic culture. Morphological parameters included root length, surface area, volume and count of lateral roots, as well as fine (diameter<0.2 mm) and thick (diameter>0.2 mm) roots. The results indicate that the root growth of all genotypes was reduced under low K, but moderate K deficiency increased the root length of the efficient genotypes. At deficient and moderate K levels, all the efficient rice genotypes developed more fine roots (diameter<0.2 mm) than the inefficient ones. Both fine root count and root surface area were found to be the best parameters to portray K stress in rice. In accordance with the root morphology, higher K concentrations were noted in shoots of the efficient genotypes when grown at moderate and deficient K levels, indicating that root morphology parameters are involved in root uptake for K and in the translocation of K up to shoots. K deficiency affected not only the root morphology, but also the root ultra-structure. The roots of high-efficient genotypes had stronger tolerance to K deficient stress for root membrane damage, and could maintain the developed root architecture to adapt to the low K growth medium.
