To preliminarily study the pro⁃angiogenic activity of Echinococcus granulosus hydatid cysts against hu⁃
man umbilical vein endothelial cells in vitro and the transcriptional level of potential pro⁃angiogenic factors. Methods The hydatid cysts and protoscolex derived from experimentally infected mice were collected and cultured in vitro,then the human umbilical vein endothelial cells were stimulated by the supernatant and cyst fluid respectively,and the angiogenesis was observed and analyzed through a microscope and the angiogenesis mode of the software NIH Image J. Meanwhile,the mouse homologous proteins of matrix metalloproteinase⁃9(MMP⁃9)and high mobility group box B1(HMGB1)were identified in E. granulosus genome through sequence alignment,and their transcriptional levels in the cyst wall and protoscolex were analyzed. Results The culture supernatant of hydatid cysts significantly promoted human umbilical vein endothelial cells into tubes(F = 73.03,P < 0.001),the transcriptions of MMP⁃9 and HMGB1 were detected in the cyst wall and protoscolex,and the transcriptional level of MMP⁃9 was higher in protoscolex(t = -11.65,P < 0.001),while the level of HMGB1 was higher in hydatid cysts(t = 6.43,P = 0.003). Conclusion Some parasite⁃derived pro⁃angiogenic molecules may exist in the supernatant of E. granulosus hydatid
cysts,while further researches are required into their exact mechanisms.

OBJECTIVE:
To analyze the clinical significance of ocular vestibular evoked myogenic potentials (oVEMP) and cervical vestibular evoked myogenic potentials (cVEMP) in primary unilateral benign paroxysmal positional vertigo (BPPV).
METHOD:
Fifty-two patients with unilateral primary BPPV (BPPV group) and 38 normal subjects (control group) received ocular vestibular evoked myogenic potential (oVEMP) and cervical vestibular evoked myogenic potential (cVEMP) test using tone burst stimuli. The response rate, latency and amplitude were analyzed.
RESULT:
In BPPV group, the response rate of oVEMP was 46.15% in lesioned side and 48.08% in healthy side, respectively. The response rate of cVEMP was 67.31% in lesioned side and 65.38% in healthy side, respectively. In control group, the response rate on the left ear was 84.21% for oVEMP and 92.11% for cVEMP. On the right ear, was 81.58% for oVEMP and 94.74% for cVEMP in control group, there was no significant difference in cVEMP and oVEMP P1, N1 N1-P1 latency and amplitude between left and right ear. The interaural amplitude ratio and asymmetry of cVEMP and oVEMP was significantly different between BPPV group and control group (P<0.05).
CONCLUSION
Unilateral primary BPPV with bilateral impaired vestibular otolith pathways function can be objectively evaluated by oVEMP and cVEMP detection. Abnormal oVEMP responses were more frequently detected than cVEMP.

Objective To evaluate the possibilities of using circulating miR-155-5p, miR-21-5p, miR-29a and miR-142-5p as biomarkers for the diagnosis of active pulmonary tuberculosis (TB).Methods Plasma samples were collected from 60 healthy subjects, 40 patients with active pulmonary TB and 20 sub-jects with latent tuberculosis infection ( LTBI) to extract miRNAs.The levels of miR-155-5p, miR-21-5p, miR-29a and miR-142-5p in plasma samples were detected by using reverse transcription-quantitative PCR. Results The levels of miR-155-5p, miR-21-5p and miR-29a in patients with active pulmonary TB were re-spectively 10.13, 7.34 and 2.74 times as much as those in healthy subjects(P<0.05).No significant differences with the level of miR-142-5p were observed between the two groups.The receiver operating char-acteristic (ROC) curve analysis of miR-155-5p, miR-21-5p and miR-29a in patients with active pulmonary TB and healthy subjects showed that the areas under the curve (AUC) were respectively 0.905, 0.830 and 0.687.The level of miR-155-5p in patients with LTBI was 3.1 times than that in healthy subjects ( P<0. 05).No differences with miR-21-5p, miR-29a and miR-142-5p were found between patients with LTBI and healthy subjects.The levels of miR-155-5p, miR-21-5p and miR-29a in patients with active pulmonary TB were respectively 3.26, 6.69 and 1.98 times than those in patients with LTBI (P<0.05).The rate of LTBI was 40.58%in people who were in close contact with patients with active pulmonary TB.Conclusion Sig-nificant differences with the levels of miR-155-5p, miR-21-5p and miR-29a were observed among healthy subjects, patients with active pulmonary TB and patients with LTBI, but no difference with the level of miR-142-5p was observed among them.miR-155-5p, miR-21-5p and miR-29a could be used as the potential bio-markers for the diagnosis of active pulmonary tuberculosis and latent tuberculosis infection.People who were in close contact with patients with active pulmonary TB could have a higher LTBI rate.
