ABSTRACT
Objective To investigate the epidemiological characteristics of human brucellosis in Ulanqab of Inner Mongolia.Methods Three hundred and twenty patients with suspected brucellosis were selected,who had registered in the Ulanqab Center for Endemic Disease Control of Inner Mongolia from April to June 2011.The investigation covered general situation,such as gender,age,occupation and main clinical symptoms and so on.Blood samples were collected,and Rose Bengal plate agglutination test(RBPT) was used for serum screening.Those who were tested positive in RBPT were confirmed with tube agglutination test (SAT).Brucellosis was diagnosed according to Diagnostic criteria for Brucellosis (WS 269-2007).Data were analyzed with statistical software(SPSS 17.0).Results One hundred and thirty-four cases were positive in RBPT of the 320 people surveyed,of which 93 cases were positive in SAT; antibody titers were higher than 1 ∶ 100(++),therefore they were diagnosed as brucellosis,and the ratio was 29.1％(93/320).The number of patients with suspected brucellosis who were negative in SAT test was 41,and the ratio was 12.8％ (41/320).Among the 93 people who were infected,the constituent ratio of farmers and herdsmen who engaged in livestock was the highest,accounted for 63.4％(59/93) and 24.7％ (23/93) of the total number of patients ; infection rate of male (30.9％,55/178) was higher than that of females (26.7％,38/142) ; the number(39) of brucellosis patients who were over the age of 51 was the highest,and the ratio is 42.0％.The onset season mainly in May and August; main route of exposure was bare hands lambing,midwifery and contact with infected sheep pollutants.Conclusions Sheep is the main source of human Brucella infection in Ulanqab.It is the key to control the spreading of brucellosis through improving awareness of disease prevention among farmers and herdsmen as well intensifying the prevention and control of Brucella infection between livestock.
ABSTRACT
<p><b>OBJECTIVE</b>To study the role of non-nutritive sucking in preterm infants requiring mechanical ventilation therapy.</p><p><b>METHODS</b>In a study of 68 preterm infants requiring mechanical ventilation, a randomly selected observation group of 35 infants was provided with non-nutritive sucking and a control group of 33 infants was not. The time to reach full enteral feeding, birth weight recovery time, body weight growth rate, hospitalization time, feeding tolerance and mechanical ventilation-related complications were compared between the two groups.</p><p><b>RESULTS</b>The time to reach full enteral feeding and hospitalization time were shorter (P<0.01), the incidence of feeding intolerance was lower (P<0.05), and the body weight growth rate was higher (P<0.05) in the observation group than in the control group. There were no significant differences in the birth weight recovery time and the incidence of mechanical ventilation-related complications between the two groups.</p><p><b>CONCLUSIONS</b>The use of non-nutritive sucking can increase growth rate, shorten hospitalization time and improve feeding tolerance in preterm infants requiring mechanical ventilation therapy. Moreover, it does not result in an increase in mechanical ventilation-related complications.</p>
