Study on the Distribution Characteristics of Traditional Chinese Medicine Syndrome Elements in Dry Eye among Internet Industry Workers
OBJECTIVE To investigate the distribution patterns of Traditional Chinese Medicine(TCM)syndrome types and syndrome elements in dry eye among internet industry workers,and explore their correlation with age,gender,and primary ocular symptoms.METHODS A random cluster sampling was conducted from November to December 2018,involving 613 young and middle-aged employees from a large internet company in Beijing.A total of 356 dry eye patients were diagnosed,and TCM syndrome assessment interviews were conducted by trained personnel using a TCM syndrome scale.The symptoms,signs,tongue,and pulse information of the patients were extracted according to the syndrome differentiation scale to determine the corresponding syndrome elements.The distribution of TCM syndrome types and syndrome elements,and their relationship with age,gender,and primary ocular symptoms were analyzed.RESULTS(1)TCM syndrome types:Among 248 dry eye patients in the internet industry,the most common TCM syndrome types were Qi and Yin deficiency syndrome(65 cases,26.21%),liver and kidney Yin deficiency syndrome(55 cases,26.18%),lung Yin deficiency syndrome(51 cases,20.56%),spleen Qi deficiency syndrome(35 cases,14.11%),Yin deficiency with damp-heat syndrome(22 cases,8.87%),and liver Qi stagnation with heat syndrome(20 cases,8.06%).(2)Syndrome elements:A total of eight core syndrome elements were extracted.Among them,the pathogenic elements(in descending order)were Yin deficiency(205 cases,82.66%),Qi deficiency(121 cases,48.79%),Qi stagnation(110 cases,44.35%),heat accumulation(91 cases,36.69%),and internal dampness(60 cases,24.19%).The location of the disease elements(in descending order)were liver(138 cases,55.65%),lung(68 cases,27.42%),and kidney(57 cases,22.98%).(3)Gender:The gender distribution among the six TCM syndrome types in dry eye patients in the internet industry showed no significant statistical differences(P>0.05).(4)Age:The comparison of the proportion of patients with liver and kidney Yin deficiency syndrome across different age groups showed statistically significant differences(χ2=13.215,P=0.001),with the proportion of dry eye patients increasing with age.There were no significant differences in the proportions of Qi and Yin deficiency syndrome,lung Yin deficiency syndrome,spleen Qi deficiency syndrome,Yin deficiency with damp-heat syndrome,and liver Qi stagnation with heat syndrome across different age groups(P>0.05).(5)Primary ocular symptoms:All 248 dry eye patients had more than two primary ocular symptoms,with the most common being fatigue(229 cases,92.34%),dryness(222 cases,89.52%),foreign body sensation(128 cases,51.61%),visual fluctuation(100 cases,40.32%),and burning sensation(93 cases,37.50%).Among these,the comparison of the proportions of different TCM syndrome types in relation to fatigue and dryness showed statistically significant differences(χ2fatigue=14.687,P=0.012;χ2dryness=11.285,P=0.046).CONCLUSIONS The most common TCM syndrome type in dry eye among internet workers is Qi and Yin deficiency,with Yin deficiency and liver being the most frequent syndrome elements.Age is correlated with the TCM syndrome type of dry eye,while gender does not significantly affect syndrome differentiation.Fatigue is the most common ocular symptom,and the presence or absence of fatigue has a certain impact on syndrome differentiation in dry eye.
