Objective To study the relationship between stabilization of patients with carotid artery atherosclerosis plaques and different traditional Chinese medicine (TCM)syndromes.Methods 60 patients with carotid artery atherosclerosis plaques were undertaken TCM syndrome differentiation and carotid Color Doppler ultrasonography tested.Results The cases of insufficiency of kidney essence and insufficiency of vital energy and blood had occupied a larger ration in stabilization carotid artery atherosclerosis plaques; while sputum and blood stasis locking collaterals syndrome and blood stasis due to Qi deficiency syndrome had statistical significance in unstabilization carotid artery atherosclerosis plaques.Conclusion Different TCM syndromes had different stabilization of carotid artery atherosclerosis.Sputum and blood stasis locking collaterals syndrome and blood stasis due to deficiency syndrome are unstable.These two syndromes are high risk syndromes of carotid artcry atherosclerosis plaques.

Objective To investigation the rule of TCM syndrome differentiation on vascular dementia,and to guide clinic therapy.Methods The vascular dementia TCM syndrome differentiation scale (SDSVD) was used for TCM syndrome differentiation of 60 cases of vascular dementia.Results The Vascular dementia has such TCM syndromes:deficiency of kidney-essence accounting for 28.3％,turbid phlegm blocking the clear orifices accounting for 23.3％,obstruction of collaterals by blood stasis accounting for 21.7％,liver Yang adverse rising accounting for 10.0％,fire-heat prosperous accounting for 8.3％,metabolic waste in viscera accounting for 8.3％.QI and blood paucity accounting for 3.3％.Conclusion The Vascular dementia has a clear TCM syndrome regularity,the syndromes of deficiency of kidney-essence accounting,turbid phlegm blocking the clear orifices,and obstruction of collaterals by blood stasis are the top three syndromes.

To study the cause and mechanism of vascular dementia.The author considers kidney deficiency and sputum stasis is the cause and mechanism of vascular dementia,so the treatment of notifying kidney to supplement marrow,activating blood circulation and removing sputum,accompanied by opening orifices medicines should be adopted.

Objective:To observe the changes of pulmonary function and its influential factors in residents of a rural community and investigate the prevention and control measures.Methods:A survey was made in residents from a rural community in Qingdao who received public health services from September 2017 to December 2019. The demographic data, behavioral and medical history information were collected. Forced vital capacity and forced expiratory volume in one second were measured. The factors that affect lung function were analyzed using univariate analysis and multivariate analysis.Results:This survey involved 5184 residents consisting of 2199 (42.4%) males and 2985 (57.6%) females. 1322 (25.5%) residents had pulmonary dysfunction. Univariate analysis showed that residents aged ≥ 60 years had a higher risk for developing pulmonary dysfunction than residents aged < 60 years (26.1% vs. 14.3%, χ2 = 19.34, P < 0.001), and male residents had a higher risk for developing pulmonary dysfunction than female residents (32.9% vs. 20.0%, χ2 = 110.74, P < 0.001). With the increase in body mass, the incidence of pulmonary dysfunction gradually decreased. The proportion of residents with pulmonary dysfunction with low body mass was higher than that in residents with normal body mass and high body mass (43.4% vs. 27.8% or 22.8%, χ2 = 8.86, 17.63, P = 0.003, < 0.001). The proportion of residents with pulmonary dysfunction was higher in those with a history of chronic bronchitis, bronchial asthma, or obstructive pulmonary disease than in those without such a history (68.3% vs. 23.2%) χ2 = 263.33, P < 0.001). The proportion of residents with pulmonary dysfunction was significantly higher in smokers, whether or not had quit smoking than in non-smokers (35.1%, 36.3% vs. 22.8%, χ2 = 48.83, 86.46, both P < 0.001). The proportion of residents with the normal pulmonary function was not related to the exposure history of dust and chemical poisons and the family history of respiratory diseases ( χ2 = 0.38, 2.29, P = 0.535, 0.130). Multivariate analysis showed that age ≥ 60 years, male sex, low body mass, smoking, and a history of respiratory system diseases were the independent risk factors for pulmonary dysfunction. Among smokers, the number of cigarettes smoked was higher in smokers with pulmonary dysfunction than those with normal pulmonary function ( t = -2.39, P = 0.009). Conclusion:There are many risk factors for pulmonary dysfunction. Primary medical service institutes should carry out pulmonary function testing and formulate targeted prevention strategies, which help realize early detection and treatment of chronic obstructive pulmonary disease.
