Objective To learn the plague's host animals and parasitic flea composition, and to investigate the natural foci of plague in Xiji county in order to provide basic information for plague prevention and control. Methods The Citellus alaschanicus density, nocturnal rodents, the body flea, the burrow track flea, the nest flea were investigated in 8 townships (town) of Xiji county from June 11 2007 to July 25 2007. Specimens of small mammalian, fleas were collected for bacteriological and serological testing. Results The average density of the main host Citellus alaschanicus was 0.85 per hectare. The nocturnal mouse capture rate was 0.80%(24/2987).The survey found 16 species of small mammals that belonging to 3 orders, 9 families and 16 species with Citellus alaschanicus the dominant species. The Citellus alaschanicus had 2.84 fleas per body. Four families and 16 species of fleas were identified in the areas. The Citellus alaschanicus and Citellophilus Tesquorum Mongolicus were the dominant species. Plague bacteriology and serology tests were negative. Conclusions The study shows that the area is suitable for the formation of natural foci of Citellus alaschanicus plague. Surveillance is an important measure for prevention and control of the plague.

Objective The surgery time for patients with infective endocarditis (IE) has been transformed.It has been supported that,for the patients with surgical indications,the surgery time should be as early as possible to improve the clinical outcome.The purpose of the research is to identify whether the patients with IE could get further benefit from early surgery.Methods Between June 1996 and July 2011,135 IE patients'data has been collected retrospectively,all of whom were verified through the modified Duke categories.The patients were devided into group A( the new therapeutic schedule group after 2008 ) and group B( the traditional therapeutic schedule group before 2008 ) by the year of 2008.The end points of observation were death associated with IE,cardiac failure,embolism,and re-infection.The comparison between the groups was by means of non-parameter rank and inspection test,variance analysis,t test,chi-square test,fisher exact test.The outcome comparison between the groups was via the Kaplan-Meier survival analysis.Results There were no significant differences in baseline data between the groups.No survival differences could be observed via the Kaplan-Meier analysis( Log Rank P =0.189).During the following-up visit,compared with the patients in group B,the mortality in group A is lower(9.4% vs.23.0%,P=0.016),the incidence of heart failu re was less in group A (5.4% vs.26.2%,P <0.001 ).No differences could be found in re-infection between the two groups(0 vs.4.9%,P =0.112 ). More patients in group A underwent surgery (67.6% vs.32.8%,P <0.001 ).Conclusion The new therapeutic sehedule of IE coull reduce the mortality rate and promote the cardiae funetion.The incidence of re-infeetion didn't increase.

Objective:To investigate the effect of segmental Le FortⅠosteotomy and bilateral sagittal split ramus osteotomy ( BSSRO ) on the condyle position in skeletal class Ⅲ malocclusion patients . Methods:In this retrospective study , 19 patients with skeletal class Ⅲmalocclusion who met the inclu-sion criteria were enrolled .All the patients underwent the segmental Le FortⅠ osteotomy and BSSRO . Cone beam computed tomography ( CBCT) scans were performed in the following phases:T1:within one week before the surgeries;T2:within one week post-surgery;T3:three months post-surgery;T4:6 to 14 months post-surgery .The posterior spaces , anterior spaces and the superior spaces of the bilateral tem-poromandibular joints were measured according to the Kamelchuk method respectively .The fossa ratios of the condyle and the distribution of the condyle positions related to the glenoid fossa ( anterior , concentric and posterior position ) were calculated .The results were analyzed statistically .Results:The posterior space , the anterior space and the superior space of bilateral temporomandibular joints in T 2 phase [ right:(2.78 ±1.23) mm, (2.47 ±0.89) mm, (3.07 ±0.85) mm; left: (2.93 ±0.83) mm, (2.69 ± 1.14) mm, (3.44 ±1.16) mm] showed significantly larger spaces than those in T 1 phase [right:(1.81 ±0.95) mm, (1.65 ±0.55) mm, (2.13 ±0.52) mm;left:(2.12 ±1.05) mm, (1.79 ±0.59) mm, (2.15 ±0.93) mm],in T3 phase [right:(2.08 ±1.25) mm, (1.79 ±0.68) mm, (1.80 ±0.76) mm;left: (2.05 ±0.75) mm, (1.99 ±0.94) mm, (2.14 ±0.71) mm] and in T4 phase [right:(1.94 ±0.77) mm, (1.81 ±0.69) mm, (2.05 ±0.69) mm;left:(1.89 ±0.69) mm, (1.80 ±0.61) mm, (2.19 ±0.75) mm], P<0.05.No significant differences were observed among T 1,T3 and T4 pha-ses in the terms of the joint spaces of both sides ( P >0.05).The fossa ratio and the condyle position related to the glenoid fossa had no significant difference in all the four phases (P>0.05).The results suggested that the condyle moved downward in T 2 phase and changed to the original pre-surgery position in T3 phase, then keot stable in T4 phase.Conclusion:Segmental Le FortⅠ osteotomy and BSSRO caused significant and transient changes of the condyle position in skeletal class Ⅲmalocclusion patients . However , the condyle tended to move back to the original pre-surgery position and might keep stable .
