Objective To investigate the risk factors of pulmonary fungal infection in patients with chronic obstructive pulmonary disease ( COPD) .Methods 48 cases of patients with COPD complicated with pulmonary fungal infection in September 2011 to September 2014 in respiratory department of Shaoxing People’s hospital ( observation group) and 48 cases without pulmonary fungal infection of COPD of patients at the same period ( control group) were selected, clinical data of two groups were retrospectively analyzed.The age, sex, antibiotics and hormone usage, serum albumin, mechanical ventilation and complications (diabetes, respiratory failure, heart failure) were compared between two groups.Results The results of sputum culture in the observation group showed that the infection rate of Candida albicans infection was 17 (35.42%), Candida glabrata was 4 (8.33%), Candida tropicalis 3 (6.25%), Aspergillosis was 22 (45.83%) and concurrent infection was 2 (4.17%).The age and sex of the patients between two groups had no statistically significant difference, the levels of serum albumin in the observation group was significantly lower than that of the control group, combined with diabetes, type II respiratory failure and right heart failure of the patients were significantly higher than that of the control group(all P<0.05).The antibiotics use time, hormone use rate and rate of mechanical ventilation in the observation group were significantly better than that of control group, the differences were statistically significant (all P<0.05).The multivariate logistic regression analysis showed that, low serum albumin, long-term use of antibiotics, mechanical ventilation, combined with diabetes and type II respiratory failure were the independent risk factors of nosocomial pulmonary fungal infection in patients with COPD.Conclusion There are many risk factors in patients with COPD complicated with pulmonary fungal infection, low serum albumin levels, long-term use of antibiotics, mechanical ventilation, combined with diabetes and type II respiratory failure are major independent risk factors.It should take active prevention and cure measures in clinic to reduce the possibility of fungal infection.
3.Discussion on Key Field of Study on Modern TCM Syndromes
Chinese Journal of Information on Traditional Chinese Medicine 2015;(7):14-16
Although the new methods and new ideas have been introduced into researches on modern syndromes, research levels of syndromes have continued to be broadened and deepened gradually. However, understanding of essential theories and general research methods have not yet achieved a broad consensus in TCM field. The phenomenon is caused by the systematic complex features of syndromes, which are difficult to be explained for a short while, and require progressive understanding and development. It is also related to the reason that current main stream researches on syndromes lack general overview and analysis. All of the above lead to the failure of efficient penetration of all syndrome researches and restrict synergetic development among these researches. This article summarized and analyzed the overview of key field of study on syndromes, and expounded their disadvantages and development suggestions, with purposes to improve future syndrome research field, enrich syndrome research methods, and promote necessary penetration of syndrome researches.
