ObjectiveTo investigate the epidemiology of Lyme disease and analyze the genotypes of Borrelia burgdorferi in five kinds of host animals of ticks in four cities of Xinjiang Uygur Autonomous Region,China.MethodsA total of 814 serum samples were collected from cattle,sheep,goats,horses and dogs in Urumqi,Ili,Changji and Kashgar Cities,and determined for IgG antibody against Lyme disease. A total of 135 ticks in the above-mentioned cities were collected,from which DNAs were extracted and used as template for amplification of the 5S-23S rRNA spacer fragments of B. burgdorferi by nested PCR. The positive samples were sequenced,and the results were compared with those of 5S-23S rRNA spacer of B. burgdorferi reported in GenBank by BLAST,and a phylogenetic tree was constructed by MEGA X software.ResultsThe IgG antibody positive rates against Lyme disease in Urumqi,Ili,Changji and Kashgar Cities were 23. 6%,2. 4%,2. 7% and 0 respectively,which showed significant difference（χ2= 48. 481,P < 0. 001）. However,the positive rates in cattle,sheep,goats,dogs and horses were 1. 1%,4. 4%,18. 7%,60. 5% and 0 respectively,which showed sig-nificant difference（χ2= 129. 03,P <0. 001）. Of the 135 tick DNA samples,24 were positive for B.burgdorferi,indicating a carrier rate of 17. 78%. Phylogenetic analysis showed that the genotypes B.garinii accounted for 75%,while B.afzelii accounted for 16. 67%,and B.burgdorferi accounted for 8. 33%.ConclusionThere are Lyme diseases in cattle,sheep,goats and dogs in Urumqi,Kashgar and Ili Cities of Xinjiang Uygur Autonomous Region,China,of which the major genotype is B.garinii.

Objective:To observe the effect of prolonging life and inhibiting tumor growth of Xiaozhensan on H22 cells-bearing mice and study the mechanism of action. Methods:①H22 cells-bearing mice models were made by subcutaneous injection and were divided into six groups:model group,low,middle and high dosage groups of Xiaozhensan,5-FU group,5-FU plus Xiaozhensan middle dosage group. After 10 days' treatment,the mice were killed and the anti-tumor rates were calculated,to detect the content of IL-2 and observe pathological sections of tumor and expression of Bcl-2 by immunohistochemical method. ②H22 cells-bearing ascites mice models were divided as the above. The living days of the mice were recorded,the prolongation of life span were calculated. Results:Xiaozhensan had the function of inhibiting the growth of tumor,and there was the dependability between quantity and effect. In pathomorphology,the sections of Xiaozhensan groups showed nuclear shrinkage,necrosis,hemorrhage,inflammatory cell infiltration on the periphery,etc. Xiaozhensan could increase the content of IL-2 and inhibit the expression of Bcl-2. Xiaozhensan combined with 5-FU can prolong the life span of the mice bearing ascites tumor. Conclusion:Xiaozhensan had the function of inhibiting the growth of tumor. The mechanism of action may be concerned with these aspects:enhancing the cellullar immunologic response and strengthening the ability to resist tumor,inducing apoptosis and weakening reproductive activity of tumor,etc. Middle dosage group of Xiao Zhen San combined with anticarcinogenic western medicin can prolong the life span of the mice bearing ascites tumor. This study provided dependable experimental documents for clinical application of Xiaozhensan,and had some guiding significance in clinic.

Objective To compare and determine the reproducibility of apparent diffusion coefficient (ADC)values of the normal liver parenchyma in respiratory-triggered,breath-hold,and free-breathing diffusion weighted magnetic resonance imaging (DWI). Methods 11 volunteers did three times of breath-hold (excitation number is 1,at the end of the expiration,thickness/gapping=5 mm/1 mm), respiratory-triggered (excitation number is 2,at the end of the expiration,thickness/gapping=5 mm/1 mm),free-breathing (excitation number is 4,thickness/gapping=5 mm/1 mm)and for a total of nine axial liver DWI,the gradient factor was 800 s/mm2 .Then they were all coronally reconstructed (thickness/gapping=8 mm/1 mm).The nonparametric test was used to compare all axial and coronally reconstructed liver ADC values;and the Bland-Altman method was used to evaluate the ADC values’repeatability in coronally reconstructed images.Results The breath-hold DWI’s mean ADC value was (1.09±0.07)×10-3 mm2/s significantly lower than the respiratory-triggered DWI(1.16± 0.09)×10-3 mm2/s and the free-breathing DWI(1.19±0.10)×10-3 mm2/s(P<0.005),the axial and coronal images’results were similar.The ADC values’average difference and scope of consistency of coronal image were (-0.09 to -0.01±0.09 to 0.48)for breath-hold DWI,(-0.04 to 0.01±0.11 to 0.17)for respiratory-triggered DWI,(-0.07 to -0.02±0.11 to 0.18)for free-breathing DWI,respectively.Conclusion The breath-hold DWI’s ADC value of normal liver parenchyma is lower than the respiratory-triggered and free-breathing DWI,and showed more poorer repeatability.It is suggested that the measurement of ADC values of the liver parenchyma should be done within the respiratory-triggered or free-breathing DWI.

BACKGROUND:Percutaneous vertebroplasty with bone cement injection for osteoporotic vertebral compression fractures can quickly relieve pain and increase vertebral strength, but vertebral re-fractures often occur because of osteoporosis. OBJECTIVE:To investigate the therapeutic effect of percutaneous vertebroplasty with bone cement injection combined with zoledronic acid in the treatment of osteoporotic vertebral compression fractures. METHODS:Six patients with osteoporotic vertebral compression fractures were enrol ed, including two males and four females, aged 60-86 years. These patients with T12-L4 vertebral fractures underwent percutaneous vertebroplasty with polymethyl methacrylate acrylate bone cement treatment. At 4 weeks after bone cement injection, al patients were administrated with intravenous injection of zoledronic acid (100 mL:5 mg) as anti-osteoporosis treatment, 30 drops per minute, once a year, for consecutive 2 years. The 2-year periodic imaging was performed to observe the clinical efficacy on vertebral compression fractures, bone density and adjacent vertebral fractures. RESULTS AND CONCLUSION:At 48 hours after bone cement injection, pain symptoms were relieved in the six cases. At the end of 2-year fol ow-up, fractures healed in al the six cases without delayed union or nonunion, and there was no bone cement leakage, nerve root compression, dural involvement, needle opening or wound infection and pulmonary embolism;the bone density was significantly higher than that before treatment (P<0.05), and no adjacent vertebral fractures occurred. These findings indicate that the percutaneous vertebroplasty with bone cement injection combined with zoledronic acid can significantly relieve pain, improve vertebral stability and bone density, and reduce the incidence of adjacent vertebral fractures in patients with osteoporotic vertebral compression fractures.
