ABSTRACT
Objective To analyze the knowledge and perceptions of brucellosis and human behavior in different populations in Jingyuan County Gansu Province,and to provide a scientific basis for carrying out health education and prevention accurately on brucellosis.Methods In 2015,using two-stage cluster sampling method,nine towns with more accumulative incidence of brucellosis in the past 3 years in Jingyuan Country were selected,5 villages were selected from each town,occupational exposure and patients with brucellosis were selected in each village as respondents.A questionnaire survey was carried out to collect basic information,brucellosis related knowledge,population's behavio.Results The overall awareness rate of prevention and control knowledge on brucellosis was 44.10％ (12 943/29 348),included 809 people with the occupation exposure population and 203 patients with brucellosis,among them,the rate of patients with brucellosis knowledge was 50.40％ (2 967/5 887),occupational exposure population was 42.52％ (9 976/23 461);There were significant differences in the awareness rate of knowledge on prevention and control of brucellosis in population of different gender,age,education and years of work experience (x2 =84.413,166.100,207.200,16.822,P ＜ 0.01);of the following parameters:shared water,peel dead lamb,How to deal with flow products,treatment of abortion without gloves,masks,not wearing gloves,masks when lambing ,to give livestock vaccines and drugs,eat dead cow,lamb,and sale of diseased,dead livestock,slaughter livestock,there were statistical significant differences between patients with brucellosis and exposure people (x2 =13.940,27.965,30.031,19.575,22.597,21.139,14.524,436.450,8.482,P ＜ 0.05).Conclusions The occupational exposure population has a low knowledge awareness rate;high risk behaviors have higher risk of brucellosis infection in Jingyuan County.We should carry out health education and high-risk behavior intervention in targeted population.
ABSTRACT
Objective To observe the clinical therapeutic effect of nucha electroacupuncture on patients with adult hypoxic ischemic encephalopathy(HIE)and to approach its mechanism. Methods After exclusion of cases with incomplete historical data from 80 adult HIE patients admitted in the Department of Critical Care Medicine of 401st Hospital of Jinan Military Region of PLA,finally 74 cases were randomly divided into a nucha electroacupuncture treatment group(38 cases)and a conventional therapy control group(36 cases)by random number table. The patients in the control group were treated with conventional medical therapies,including dehydration,intracranial pressure reduction,brain protection with head hypothermia,and so on. In nucha electroacupuncture group,based on the conventional treatment in the control group,additionally nucha electroacupuncture was performed for the patients. Before and after therapy,the changes of Glasgow coma scale score(GCS score)and Glasgow-Pittsburgh coma score (G-PCS score)in all the patients were assessed and compared between the two groups,and according to the standard criteria of GCS and G-PCS scores for evaluation of efficacy,the clinical therapeutic effective rates in the two groups were assessed. Results ①There were no statistically significant differences between the two groups in GCS score and G-PCS score before treatment(both P>0.05),after treatment,the GCS and G-PCS scores in nucha electrical acupuncture group were obviously higher than those before treatment(GCS score:6.22±2.66 vs. 4.33±1.35,G-PCS score:22.96±6.22 vs. 17.53±4.68,both P<0.05),and the GCS and G-PCS scores of nucha electroacupuncture group were markedly higher than those of control group after treatment(GCS score:6.22±2.66 vs. 5.17±3.01,G-PCS score:22.96±6.22 vs. 16.78±7.96,both P<0.05).②The total effective rate of nucha electroacupuncture group was significantly higher than that of control group when assessed by both the standard criteria of GCS score(73.7%vs. 50.0%,P<0.05)and G-PCS score(84.2%vs. 61.1%,P<0.05). Conclusion The nucha electroacupuncture has definite clinical therapeutic value in treatment of patients with adult HIE and it can improve their neurological function and outcome.
ABSTRACT
Objective To investigate N-terminal pro-B-type natriuretic peptide (NT-proBNP) cutoff value for the mortality in different age groups in critically ill patients.Methods A retrospective study was conducted.295 patients admitted to the intensive care unit (ICU) of 401st Hospital of PLA from January 2011 to October 2012 were divided into two groups according to age [group with age＜65 years old (n=105) and group with age≥ 65 years old (n =190)].The concentrations of serum NT-proBNP,hematocrit (HCT),procalcitonin (PCT),C-reactive protein (CRP),serum creatinine (SCr),estimated glomerular filtration rate (eGFR),acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and probability of survival (PS) were recorded within 24 hours.The primary outcome was ICU mortality.Receiver operator characteristic curve (ROC curve) was used to evaluate the value of NT-proBNP for predicting the mortality.Results ① There were no significant differences in the length of stay in ICU,mechanical ventilation rate,the mortality,the incidence of cardiovascular disease,digestive disease,neurologic disease,and the number of patients having received operation,HCT,PCT and CRP between the two groups (all P＞0.05).The percentage of the male,the APACHE Ⅱ score,the percentage of respiratory disease,and NT-proBNP in group with age ≥ 65 years old were higher than those of the group with age ＜ 65 years old [the percentage of the male:51.6％ vs.33.0％,x2=9.093,P=0.003; APACHE Ⅱ score:22.94 ±8.10 vs.19.44 ±8.51,Z=-3.259,P=0.001; the percentage of respiratory disease:29.47％ vs.17.14％,x2=5.472,P=0.024; NT-proBNP(ng/L):5 859.00(2 050.75,23 802.75) vs.2 882.00 (275.15,6 236.00),Z=-5.514,P=0.000]; PS,the percentage of patients having multiple injuries and other diseases and eGFR in group with age ≥65 years old were lower than those of the group with age ＜65 years old [PS:59.0 (31.5,79.0)％ vs.70.0 (40.0,84.0),Z=-3.431,P=0.001; the percentage of multiple injuries:0.53％ vs.17.14％,x2=30.987,P=0.000; the percentage of other disease:5.79％ vs.13.33％,x2=4.962,P=0.030; eGFR (ml·min-1· 1.73 m-2):81.07 (45.77,131.80) vs.95.54 (33.64,165.55),Z=-2.214,P=0.027].② The area under the ROC curve (AUC) [95％ confidence interval (95％ CI)] of NT-proBNP in patients with age＜65 years old was significantly higher than that of group with age≥65 years old and the entire group [0.825(0.738-0.892) vs.0.664 (0.592-0.731) and 0.725 (0.670-0.775),Z1 =-2.835,P1 =0.005; Z2=-1.995,P2=0.046].③ The sensitivity (76.]0％ vs.64.10％),specificity (82.35％ vs.67.12％),positive predictive value (90.0％ vs.75.8％),and negative predictive value (62.2％ vs.53.8％) with cutoff value of NT-proBNP (2 882 ng/L) in group with age ＜65 years old were significantly higher than those with NT-proBNP cutoff value (6 062 ng/L) in group with age ≥ 65 years old.Conclusion NT-proBNP cutoff value in different age groups for the prediction of mortahty in the critically ill patients maybe more objective and accurate.
