OBJECTIVETo investigate the prevalence of hearing impairment and ear diseases in old people and provide scientific data for drawing up the prevention and treatment strategies.

METHODSUsing the probability proportion to size (PPS) method, 1261 people over 60 years were investigated in 40 clusters in Jiangsu Province with the WHO protocol.

RESULTSThe prevalence of hearing impairment was 58.1% (the standardized rate: 59.5% in the whole country, 60.9% in Jiangsu province). Degrees of hearing impairment were mild (33.1%), moderate (17.8%), severe (5.9%) and profound (1.3%). The prevalence of hearing disability was 25.0% (the standardized rate: 26.6% in the whole country, 28.1% in Jiangsu province). There were significant difference of the prevalence between male and female, as well as urban and rural, and different ages. The prevalence of the ear diseases was auricle malformation (0.2%), wax (1.7%), otitis externa (0.1%), fungi (0.5%), serous otitis media (1.2%), chronic suppurative otitis media (1.6%), dry perforation of tympanic membrance (2.3%). The causes of hearing impairment were ear diseases (2.9%), non-infectious condition (92.6%), genetic condition (0.3%) and undetermined causes (4.2%). Of which, 31.1% of persons needed hearing aids while 2.3% of persons needed medicine treatment, but 0.9% of persons needed non-urgent surgery and 1.0% of persons needed other treatment.

CONCLUSIONSThe prevalence of hearing impairment and disability in the old rised obviously than the last investigation in 1987. It was a heavy burden for social development in China. The government and the whole society should take more concern about the problem. The scientific strategies of prevention and treatment were urgently needed and implemented.

It is necessary to investigate the influence of the rationality of clinical drug use on the benefit and risk factors of traditional Chinese medicine injections. The retrospective survey was based on the medical records and information of 4 950 patients who used Danhong injection in the HIS database of the first affiliated hospital of Nanjing University of Chinese Medicine from 2013 to 2014. The basic statistical methods and associated rules analysis were utilized to analyze the HIS information of these patients, including the basic information, the diagnosis, the department, the dosage, the usage of medication, the drug combination and the adverse reactions. And the rationality analysis of the clinical application of Danhong injection was carried out to investigate relevant factors of the adverse reactions. The results showed that most cases came from the department of cardiology (51.95%) and encephalopathy center (20.67%). In the statistical period, the patients aged above 40 years old accounted for 96.65%. And the two western medicine diagnosis items with the highest confidence level were coronary heart disease and angina pectoris (97.15%), while the three items were coronary heart disease, angina pectoris and hypertension (97.02%). The irrational indications were mainly hypertension (12.93%) and diabetes (4.55%). All of them were diagnosed as blood stasis syndrome by the traditional Chinese medicine. About 98.93% of the single dosage was within the range stipulated on package insert, the duration mainly ranged between 1 and 21 days, and 97.64% of the menstrua contained 0.9% NS and 5% GS. According to the medication records,99.26% were the use of combined drugs, with 8.41 drugs on average. Antiplatelet drugs (72.04%) were the most frequently combined with western medicine, followed by the cholesterol-regulating drugs (64.86%) and the cerebrovascular drugs (60.26%). When used in the combination with antibiotics for the infection, cephalosporin antibiotics were the most frequently applied (8.81%). When used with traditional Chinese medicines, traditional Chinese medicines for activating blood circulation and removing blood stasis or monomer traditional Chinese medicine injections (28.93%) were the dominance, in which Gastrodin injection was the most frequently applied (16.23%). And 12 cases of adverse reactions were reported, with the ADR rate of 0.24%. The indications, solvent compatibility and irrational drug combination may be the potential risk factors for ADRs induced by Danhong injection. Further experiments are required to evaluate the benefits and risks in these three aspects.

There is still a need for better protection against or mitigation of the effects of ionizing radiation following conventional radiotherapy or accidental exposure. The objective of our current study was to investigate the possible roles of matrix metalloproteinase inhibitor, ilomastat, in the protection of mice from total body radiation (TBI), and the underlying protective mechanisms. Ilomastat treatment increased the survival of mice after TBI. Ilomastat pretreatment promoted recovery of hematological and immunological cells in mice after 6 Gy γ-ray TBI. Our findings suggest the potential of ilomastat to protect against or mitigate the effects of radiation.
