The morbidity of scoliosis in adolescents in China is about 3%-5%, 80%-85% of the patients are adolescent idiopathic scoliosis (AIS), whose etiology is unknown. Scoliosis is a structural spine disease occurring during puberty or before skeletal maturation. Scoliosis has a greatly negative impacton not only the growth and development of adolescent spine, but also the mental health of adolescents. Ocular disease is a common clinical disease in which the eye ball and its accessory structures have structural abnormalitiesordys function. Ocular disease snotonly bring in convenience to patients's life, but also may induce diseases in other organs. Recent studies have shown that various ocular diseases may have a potential impact on scoliosis, and quite a fewof patients with certain ocular diseases have higher incidence rate of scoliosis. Therefore, in this article, the etiological relationship between eye diseases and scoliosis will be summarized, which provides guidance and direction for the etiological research of scoliosis and eye diseases. After sorting out, we found that the relationship between ophthalmic diseases and scoliosis mainly concentrated in the following four aspects: choroidal thickness and scoliosis, Goldenhar syndrome, gene level and strabismus. Among them, the genetic relationship is the most complex, about 40 kinds of gene or chromosome abnormalities have been found to cause ocular diseases and scoliosis; Goldenhar syndrome, also known as oculo-auriculo-vertebral spectrum, first revealed the relationship between ocular diseases and scoliosis, but the current statistical relationship is still very vague. There are few studies on choroidal thickness and strabismus at home and abroad, which are statistical studies, only revealing the relationship between choroidal thickness and scoliosis, and there are many defects in the study of choroidal thickness, which need further research.

Objective:To establish a diagnostic system for heat toxin syndrome of acute cere-bral infarction.Based on this toxin syndrome diagnostic system,the general principles of heat toxin development will be uncovered,and the critical turning point at which the heat toxin syndrome occurs will also be explored.Methods:In this study,a total of 271 hypertension patients with cerebral infarction within 72 h were recruited from the Affiliated Dongfang Hospital of the Beijing University of Chinese Med-icine,the Affiliated Dongzhimen Hospital of Beijing University of Chinese Medicine,the Affil-iated Renmin Hospital of Peking University,the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine,the Affiliated Hospital of Shandong University of Traditional Chinese Medicine,the Affiliated Hospital of Changchun University of Traditional Chinese Medicine,the Affiliated Hospital of Hebei University of Traditional Chinese Medicine and China Meitan General Hospital from August,2008,to December,2009.The patients' Chi-nese medical information was recorded on days 1,3,5,7,and 14 during their hospitalizations.The medical records were recorded according to traditional Chinese medicine (TCM) theory and included the serum marker levels at the beginning and at the end of the trial.The time line was also analyzed.Results:The level of Hs-CRP,PAG,NSE,OX-LDL,and MMP-9 were abnormal and,were higher in CI patients compared to hypertension patients.In the study of the heat toxin diagnosis system,according to the entropy clustering results,30 combinations of the medical information can be sorted into the traditional syndromes,but 13 combinations cannot be sorted.To obtain more precise symptoms related to the heat toxins,a logistic regression equation was set up with the variables from the unsorted medical information;the dependent variables were fever and BP fluctuation.Weighted variables were obtained.MLP analysis demonstrated that the diagnosis model was stable and precise.The accuracy reached 83.82%.The ROC test showed that seven points of the diagnosis system was the best cutting point,with a sensitivity of 0.857 and a spec-ificity of 0.955.Progressing stroke was related to heat toxin syndrome.When the turning point appeared,the combination of symptoms,such as coma,aphasia,gummy eyes,and halitosis,predicted the deterioration or recovery of Cl.The heat toxin syndrome existed in every sub-type of Cl;however,the observed heat toxin levels were highest in PACl and lowest in LACl.Meanwhile,blood and sputum stasis syndromes transformed into heat toxicity were one source of heat toxin syndrome.Conclusion:Heat toxin syndrome,as well as qi/blood/sputum stasis,co-existed in the CI pa-tients,and the transformation frequently appeared during the process.Three to five days after the onset of Cl was the turning point,at which time several combinations of medical indicators make it possible to predict the development of Cl.
