ABSTRACT
Objective To analyze the epidemiological surveillance results of human brucellosis in Shanxi Province from 2012 to 2017,to know the epidemic status of brucellosis,and to provide evidence for prevention and control of brucellosis.Methods Incidence date and surveillance date of disease outbreaks in Shanxi Province from 2012 to 2017 were collected,the retrospective analysis method was used to analysis the "three distribution" of brucellosis,outbreak situation and the results of serological and pathogenic surveillance in the 4 surveillance stations.Results A total of 36 220 brucellosis cases were reported from 2012 to 2017,the average incidence was 16.62/100 000;8 540 brucellosis cases were reported in 2014,with incidence 23.53/100 000;a total of 23 197 cases of brucellosis were reported mainly in Datong,Shuozhou,Jinzhong and Xinzhou,accounting for 64.04％ of the province total.The onset was seasonal,and the peak of the epidemic was from March to August,accounting for 67.23％ (24 350/36 220).The brucellosis cases were mainly youth (23 084),male (28 317),farmers and herdsman (32 616).In the 4 surveillance stations of the brucellosis,39 140 cases were investigated,of which 10 536 cases did serological test,in which 585 were positive for Brucella (5.55％).The highest positive rate of serological test was 9.50％ (226/2 738) which was found in Tianzhen.A total of 626 samples carried out pathogen culture,in which 107 strains of brucellosis were detected,the detection rate was 17.09％,and 106 strains Brucella were melitensis biovar 3 of the total strains except 1 mutant.Conclusions The reported incidence in Shanxi Province is in a decline tendency,but the situation of brucellosis epidemic is still relatively serious.It is suggested that the surveillance work should be strengthened;the epidemic situation of brucellosis should be mastered in time and effectively controlled.
ABSTRACT
Objective To explore epidemiological characteristics of brucellosis in Shanxi Province during 2011-2015,and to provide evidences for making control and prevention strategy.Methods Data and surveillance data of disease outbreaks in Shanxi Province from 2011 to 2015 were collected.The retrospective analysis method was used to analyze the population distribution,regional distribution,time distribution,outbreak situation,serological and pathogenic test results of brucellosis.Results During 2011-2015,totally 33 697 brucellosis cases were reported,with an average annual incidence of 18.65/100 000,and one death case was reported.Brucellosis distributed in 119 counties (districts) of 11 cities.The area with most reported brucellosis cases was Datong City.The incidence of the disease had seasonal fluctuation and the incidence peak was from March to July.The male/female ratio of the cases was 3.69 ∶ 1.00 (26 515/7 182).Totally 75.77％ (25 531/33 697) were at the ages of 40-＜ 70 years.The yearly proportion of the cases occurred in the age groups was significantly different (H =146.263,P ＜ 0.05).Farmer was the predominant occupation group among the cases [82.90％ (27 935/33 697)].Totally 16 cases of human brucellosis outbreaks were occurred during the five years.The epidemic spread to seven counties in five cities.Totally 144 136 cases received serological test,the positive rate was 5.85％ (8 426/144 136),and 6 759 cases were found.Totally 164 strains of Brucella melitensis were isolated in human blood culture samples.All of which were Brucella melitensis biotype 3.Conclusions In recent years,the epidemic situation of brucellosis in Shanxi is severe,the total incidence has presented a rising tendency.There are outbreaks of human brucellosis in some countries.Brucella melitensis biotype 3 is the epidemic strain in Shanxi.
ABSTRACT
Objective To explore the relationship between serum homocysteine (Hcy) level before coronary angiography(CAG) and contrast induced nephropathy (CIN) after CAG.Methods We included 2264 cases of suspected coronary heart disease from May 2013 to May 2016 and all patients received CAG examination.According to whether CIN has developed or not after CAG, the patients were divided into the non-CIN group (n=2162) and the CIN group (n=102).We analyzed and compared the clinical baseline data, serum Hcy and creatinine (Cr) levels and the estimated glomerular filtration rate between the 2 groups eGFR.Results Patients in the non-CIN group were younger and with less comorbidities of diabetes and chronic kidney disease (all P0.05).At 72 hours after CAG, Cr level of the non-CIN group (69.34±19.54 μmol/L) was lower than that of the CIN group (87.34±21.38) μmol/L (P<0.05).eGFR was higher in the non-CIN group (79.34±19.54)ml/min than that in the CIN group (67.34±21.38)ml/min (P<0.05).Linear regression analysis showed that Hcy level before CAG were positively correlated with Cr level after CAG (r=0.547,P<0.01) and negatively correlated with eGFR after CAG (r=-0.271,P<0.01).Conclusions Hcy level before CAG can be used as one of an effective parameter to predict CIN.
ABSTRACT
Objective Exploring clinical prediction value of the ischemia modified albumin (IMA) for acute coronary syndrome (ACS) patients after the percutaneous coronary intervention (PCI).Methods A total of 109 cases of the PCI postoperative patients of ACS at the Panggang General Hospital from January 2010 to July 2012 were included.IMA was determined within 6 hours after admission,and standardized treatment after PCI.After a 6-month follow-up,they were divided into the event group and non-event group according to cardiovascular events occurrence.Results 101 cases were followed-up,including 26 cases of cardiovascular events (25.74％) and 75 cases of no cardiovascular events (74.26％).The left ventricular ejection fraction of the event group [(45 ± 7)％] was significantly lower than the non-event group [(52 ± 10) ％] (t =1.894,P ＜ 0.05).Serum IMA of the event group[(105.51 ± 13.26) U/ml]was significantly higher than the non-event group [(85.18 ± 11.36) U/ml] (t =7.3518,P ＜0.01).After controlling other cardiovascular risk factors,IMA was still independent risk factors for cardiovascular events (OR =1.69,95％ CI: 1.18 ～ 2.13,P =0.01).Conclusions IMA have very good clinical prediction value of cardiovascular events occurrence for ACS after PCI.
