To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Objective In this paper we analyzed the major risk factors of hemorrhagic fever with renal syndrome(HFRS) as well as its clinical manifestation,so as to provide a basis for clinical diagnosis and effective control of HFRS in Xi'an.Methods The method of retrospective study was used to collect clinical data of hospitalized patients with HFRS between 2005 and 2010 in the Hospitals for Infectious Diseases in Xi'an city,Zhouzhi and Huxian counties and then clinical manifestations of the patients with HFRS were analyzed and classified according to the national standards for clinical symptoms and test indicators of HFRS.HFRS patients matched by the ratio of 1 ∶ 2 healthy human controls were retrospectively investigated in order to obtain risk factors relevant to HFRS incidence using casecontrol study.Odds ratio(OR) method was used for single factor study.While for the multifactor study,we took the conditional Logistic regression approach.We also built models for both studies.Factor with OR > 1 and P < 0.05 was judged to be a risk factor.Results A total of 3090 cases information of patients with HFRS and 6018 healthy controls were collected.Of the 3090 cases of HFRS patients,sixty vaccinated patients showed atypical clinical manifestations and they were mild or moderate cases and no deaths.A total of 3030 nonvaccinated patients had obvious clinical symptoms.Severe or critical cases accounted for 39.07%(1184/3030)and 60 patients died and the fatality rate was 1.98% (60/3030).The results of single factor Logistic regression analysis showed that of the 16 factors analyzed,the difference of 11 risk factors between the case group and the control group was statistically significant.Multivariate Logistic regression analysis showed that of the 11 factors,the difference of six factors between the case group and the control group was statistically significant.The main risk factors of suffering HFRS in the order were:exposure to rat pollutants,living in the affected areas,sitting or lying on grass fields in the affected areas,working in the affected areas,house rat infestation,and domesticated cats or dogs(OR =6.826,5.764,4.882,4.857,3.126 and 2.875; P < 0.01 or P < 0.05).Conclusions Vaccines are very useful in the sense that vaccinated HFRS patients tend to have mild symptoms and good prognosis.Health education in this area should be focused on the six risk factors in order to prevent the spreading of HFRS.

<p><b>OBJECTIVE</b>To study how to perform the hearing screening on the infants in the rural area.</p><p><b>METHODS</b>Three thousand nine hundreds and twenty-two infants, about 84% of them from rural, were born in the People Hospital of LaiZhou City from January to December in 2004. The infants were performed fast hearing screening by transient evoked otoacoustic emission (TEOAE) after the birth in 2-7 days. The fail cases were checked again after 4-6 weeks, and then were diagnosed if they still failed after following-up.</p><p><b>RESULTS</b>The infants (3612/3922, 92.1%) have been checked by TEOAE, and the examination was free in the poverty cases. The rate passed on the first check was 69.96% (2527/3922), but 1085 infants failed (30.4%), while 310 infants have not been checked (7.9%). In the 1085 cases that should be rechecked, there was only 633 cases (58.34%) accepted the check on time, while 452 cases (41.66%) missed. In the 163 cases with high-risk infants in 2004, 114 infants (69.96%) were checked, but 49 infants (29.04%) were not checked. Fourteen cases failed in the recheck, and 11 of them were checked by ABR. Two cases were found to be moderate and severe hearing loss in binaural respectively and 4 cases with mild hearing loss in monaural while 3 cases were normal.</p><p><b>CONCLUSIONS</b>It is necessary and viable for the infants on hearing screening in the rural area It should be set up and perfected the model for infants on hearing screening in rural area as soon as possible; it should be free for the poor infants to make sure everyone enjoy the health care.</p>

<p><b>OBJECTIVE</b>To investigate the children with hearing loss from the age 0 to 6, and discuss the found age, found way and audiological characteristics.</p><p><b>METHODS</b>General information of found age and found way of 265 children, were investigated with self-made questionnaire and routine audiological evaluations, and then made statistical analysis.</p><p><b>RESULTS</b>The average (x +/- s) found age for the children with hearing loss was (23.21 +/- 10.02) months, and the first average coming age was (28.01 +/- 13.41) months. The found age of girls [(27.11 +/- 13.13) months] was 6.1 months later than the boys' [(21.03 +/- 12.32) months] and the countryside children [(28.27 +/- 11.09) months] later than the city's [(19.52 +/- 13.05) months] 8.65 months in the average found age. The found age of children who were found with speech disability was later than others. As the hearing loss degree of children went milder, the found age might later.</p><p><b>CONCLUSIONS</b>The popularization of knowledge in preventing from hearing loss must be strengthened. It is also necessary to popularize newborn hearing screening and early intervention while to enhance the parents' consciousness.</p>
