Objective By analyzing the epidemiological characteristics of brucellosis in Shanxi Province,to provide a scientific basis in formulation of strategies for effective prevention and control of the disease.Method Surveillance data of human brucellosis from China Information System for Disease Control and Prevention between 2004 and 2013 were statistically analyzed by descriptive epidemiological method.The regional,time,age and sex,occupational distribution of brucellosis were analyzed.The prevalence trend of brucellosis in Shanxi Province was summarized.Results From 2004 to 2013,the total incidence presented a rising tendency and the highest reported incidence was 19.10/10 million in 2013.A total of 43 061 cases of brucellosis occurred in Shanxi Province.The average incidence of brucellosis was 12.52/10 million.Regional distribution range was relatively focused on the north areas of Shanxi Province,the number of reported cases of Datong City was the largest (12 157 cases),being 28.23％.The incidence of Shuozhou City was the highest (42.97/10 million).The epidemic was spreading through all county areas.The disease was found each month throughout the year,the obvious incidence peak seasons were between March and June.The disease was most commonly found in 15-64 age groups(87.19％,37 545/43 061).Occupation distribution of patients was mainly farmers (83.34％,35 887/43 061).Conclusions The situation of brucellosis epidemic in Shanxi Province is relatively serious;the reported incidence of brucellosis in Shanxi Province is in a rapid upward trend year by year,even highly active in some particular areas.Different regions should establish regional mechanisms for joint prevention and control and implement different prevention and control measures to comprehensively and sequentially control brucellosis.

Objective To assess the Chinese System for Cardiac Operative Risk Evaluation (SinoSCORE) model in patients undergoing heart valve surgery at our center.Methods From January 2009 to December 2011,2098 consecutive adult patients who underwent heart valve surgery at our center were collected and scored according to the SinoSCORE model.All patients were divided into three risk subgroups.The entire cohort and each risk subgroup were analysed.Calibration of the SinoSCORE model was assessed by the Hosmer-Lemeshow(H-L) test.Discrimination was tested by calculating the area under the receiver operating characteristic (ROC) curve.Results Observed mortality of all 2098 patients was 3.00％.Despite there were significant differences between the SinoSCORE population and our own population sample,the SinoSCORE model showed good calibration(Hosmer-Lemeshow:P =0.783) and discriminative power (area under the ROC curve of 0.752)in predicting in-hospital mortality at the entire cohort.Conclusion The SinoSCORE model give an accurate prediction for individual operative risk in heart valve surgery patients at our center.

Objective:To summarize the results and methods of surgical treatment for type A aortic dissection with small true lumen of the descending aorta.Methods:9 patients underwent surgical treatment for type A aortic dissection with small true lumen of the descending aorta between January 2017 and December 2019 were analyzed retrospectively. There were 7 males and 2 females, mean age of (41.6±9.2) years. Acute dissection were 2 cases, and chronic dissection were 7 cases. Preoerative computed tomography was used to diagnose the dissection and evaluate the true lumen of the descending aorta. This procedure was done in all patients via a median sternotomy under hypothermic CPB with SCP. 4-branched prosthetic graft was used to replace the ascending aorta and aortic arch. The procedures involving the descending aorta: Hybrid surgery using TEVAR. Distal intimal flap fenestration. Implanting the intraoperative stent-graft or prosthetic graft at false lumen for second-step operation.Results:There was no in-hospital mortality. Stroke, Spinal cord, visceral ischemia and lower limbs malfunction were not observed. Reintervention was not found in case with acute dissection during follow-up. One patient who reveived fenestration underwent TEVAR, others with chronic dissection underwent thoracoabdominal aortic replacement 3 months after surgery.Conclusion:Hybrid or staged procedures was a suitable alternative to patients with type A aortic dissection with small true lumen of the descending aorta.

Objective To discuss the diagnosis and surgical treatment of the primary right ventricular tumors.Methods The results of surgical treatment of 7 patientss (5 males,2 females; median age,48 years,range,37 to 68 years) with primary right ventricular tumors hospitalized from Jan,1999 to May,2012 were analyzed.By preoperation echocardiography,cardiac myxoma was diagnosed in 2 cases,and cardiac space-occupying lesion was diagnosed in 5 cases.Median sternotomy were performed in all the 7 cases for biopsy or resection of tumor.when resection of tumor,extracorporeal circulation and cardiac arrest were performed.Results The 7 patients accounted for 4.96％ of patients with cardiac tumors surgically treated in the corresponding period.Complete resection of tumor was performed in 5 cases,and only biopsy in 2 cases.The pathological diagnoses included myxoma in 2 cases,lipoma in 1 case,liomyoma in 1 case,undifferentiated sarcoma in 1 case,and mesenchymal sarcoma in 2 cases.There was no in-hospital death.During a follow-up of 1 ～ 51 months (median,38 months),the 3 cases of sarcoma died,and the other patients were good and showed no recurrence.Conclusion The incidence rate of primary right ventricular malignant tumor is relatively high.Echocardiography is the most important diagnosis method.The prognosis of right ventricular malignant tumor is poor.The results of surgical treatment of right ventricular benign tumor are satisfactory.

ObjectiveTo retrospectively analyze clinical data of patients who has left-side valvular disease combined with severe tricuspid regurgitation and evaluate the effect of our modified tricuspid annuloplasty with enforcement of artificial felt strip.Methods76 patients who had left-side valvular disease combined with severe tricuspid regurgitation received operations between Jan.2008 and Jun.2010.The average age of the patients was 53.5 years old (32 male and 44 female).Besides the severe tricuspid regurgitation, other combined cardiac impairments included mitral valvar disease (52 cases), aortic valvar disease(5 cases), double valvar disease(19 cases) and left atrial thrombosis(22 cases).6 patients had grade II cardiac function according to the NYHA criteria, while 47 and 23 were in grade III and IV, respectively.Other signs included cyanosis(5cases), jaundice(11 cases), neck vein engorgement(48 cases) , ascites(22 cases), hepatomegaly(41 cases) and pitting edema in the lower limbs(68 cases).The concomitant operative procedures included mitral valve replacement in 52 patients,aortic valve replacement in 5 patients, double valve replacement in 19 patients, removal of left atrial thrombus in 22 patients,left atrium folding in 21 patients and left atrium appendage suture in 68 patients.Left-sided valve disease were corrected first,TAP was performed on the beating heart after the heart had been defibrillated.The anteroseptal commissure was plicated first.A double-armed 3-0 pledgeted suture was taken through the base of the septal leaflet, 5-6 mm from the commissure, extending along the annulus, and out from the point in the anterior annulus 10-12 mm from the anteroseptal commissure.Both ends of the suture was tied until the two Teflon pledgets approximated each other near the commissure.Then a semicircular De Vega type of plicating with a 3-0 prolene was taken, starting just from the anterior annulus near the anteroposterior commissure, and extending clockwise to a point just cephalad to the posteroseptal commissure.The suture was tied with positioning a 27-29 mm valve siser across the tricuspid valve.At last, a 3-5 mm width felt strip was prepared and was sutured to the plicated posterior annulus region with interrupted mattress sutures of 2 to 3 2-0 prolene.A favorable result was considered when TR was not marked by saline injection.Echocardiography was routinely examined one week postoperatively and patients were followed up 6 month after discharge.ResultsThere is no death in all patients.The CVP diminished significantly from 16mmHg preoperatively to 8mmHg postoperatively (P = 0.0021).The systomic pulmonary pressure diminished from 59 mmHg preoperatively to 41 mmHg postoperatively (P = 0.038).Echo one week postoperative showed no tricuspid regurgitation in 56 patients and mild in 18 patients, while 2 had moderate tricuspid regurgitation.The diameter of right atrium diminished significantly postoperatively, too.The ejection fraction was improved even though there was not significant difference as compared with preoperative data.The cardiac function of all patients improved and the signs of right heart failure were alleviated or disappeared.Follow up 1 to 36 months showed no change of the regurgitation except for one become moderate from mild when discharged.No hepatic congestion or edema was observed in all patients.ConclusionThese new modifications make the technique more selective in the remodeling of the tricuspid annulus.It could achieve better coaptation of the anterior leaflet with the others, successful annular reduction, better maintenance of the contractile property of the tricuspid ring, better distribution of pursing force in the more dilated region.It could prevent the tear of the endocardium in the posteroseptal region in the long period of time postoperatively.

Objective To explore and conclude the influence factors of long-term outcomes of mitral valve repair for moderate and severe mitral regurgitation due to myxomatous degeneration.Methods To review the in-patient data and followup outcomes of 261 patients after mitral valve repair for moderate and severe mitral regurgitation due to myxomatous degeneration from Jan 1993 to Jan 2008 in Changhai Hospital of Second Military Medical University.Results There were 7 perioperative deaths and 254 survivors who obtained satisfactory perioperative outcomes.During the follow-up,24 patients were lost and 230 patients were followed up from 36 months to 174 months (77.3 ±30.3) months and follow-up rate was 90.6％.Multivariate Cox regression shows age ≥ 60 years old,left ventricular ejection fraction ＜ 0.50,undergoing combined coronary artery bypass grafting were the independent risk factors for long-term death after operations and left ventricular ejection fraction ＜ 0.50,New York Heart Association functional classification Ⅲ-Ⅳ,anterior leaflet prolapse were the independent risk factors for long-term recurrent moderate or severe mitral regurgitation after operations and prosthetic ring or band annulopasty was a protective factor.Conclusion The age ≥60 years old,left ventricular ejection fraction ＜ 0.50,undergoing combined coronary artery bypass grafting,New York Heart Association functional classification Ⅲ - Ⅳ,anterior leaflet prolapse,and prosthetic ring or band annulopasty were closely related with long-term adverse events after operations.

Objective To summary the methods and results of first and second operations on patients with aortic valve disease and non-specific aortitis.Methods The total 34 patients including 23 cases with aortitis and 11 cases with Behcet disease were studied from Jan 2000 to Dec 2010.The first operation was Bentall procedure in 18 cases and AVR in 16 cases.Fourteen of 16 cases who had AVR developed severe paravalvular leakage,and undewent the second operation including 10 aortic root replacement (8 valve-conduit and 2 homograft) and 4 non-anatomic AVR.Results Eighteen patients who had first operation of Bentall procedure all survive without aortic pseudoaneurysm after the follow-up of 6 months to 11 years.Fourteen redo cases all survive except for one case died of repture of aortic pseudoaneurysm 1.2 years postoperatively.Conclusion Preoperative diagnosis in these patients is very difficulty.The first operation of root replacement is of choice.The second operation is very difficulty to handle,root replacement can achieve satisfactory results.Non-anatomic AVR is easy to perform,and good hemo stasis intraoperatively,and is a satisfied alternative method with good results.
