Babesia parasites are obligate intracellular apicomplexan protozoa and important pathogens causing babesiosis of humans and animals. They have conserved subcellular structures and invasion mechanism. Rhoptry⁃associated proteins,which are released into the host cell,are considered to be the key molecules of invasion and replication of parasites in the host cell and are immunosuppressive factors of the host cell mediated immunity in the stage of parasitophorous vacuole(PV)formation. The knowledge about rhoptry⁃associated proteins has made a great progress with the development of genomics and proteomics,so we review the research progress in rhoptry⁃associated proteins of different Babesia including Babesia bovis,B. ovine,B. gibsoni,B. bigemina and B. orientalis,etc.

Objective BOLD-fMRI was used to observe the activated auditory cortex evoked by pure tone stimuli in patients with sensorineural hearing loss and this paper is to discuss the objective measure for patient with sensorineural hearing toss. Methods BOLD-fMRI examinations were taken in 22 patients with unilateral moderate to severe sensorneural hearing loss and 15 control subjects. The volumes and intensities of the two hemispheres of the activated auditory cortex were analyzed quantitatively. Results Significant activation was found in the temporal lobe in control subjects, and significant differences in the volume and intensity were noted between the contralateral and ipsilateral activated auditory cortexes in them (P<0.01), exhibiting clearly eontralateral predominance. When the normal ear of patients with sensorineural hearing loss received signals, there was no significant difference be-tween contralateral and ipsilateral activated auditory cortexes (P>0.05). Conclusion When the normal ear of pa-tients with sensorneural hearing loss was stimulated by pure tone, the contralateral hemisphere predominance disap-peared. This result seems to show the plasticity of auditory cortex of patients with unilateral hearing loss.

Objective To investigate the optimal ultrasound exposure parameter on H22 neoplasms of mice meditated by ultrasound exposure combined with self‐made nanobubbles ,and then observe their therapeutic effect combined with cisplatin and their possible mechanism of anti‐tumor . Methods Thirty mice engrafts models with subcutaneous H22 neoplasms were established and divided into 6 groups randomly ,which received ultrasound exposure at different intensity and exposure time . The contrast enhanced ultrasound imaging ( CEUS ) was performed in every group at the four time points of before treatment and at 0 h ,24 h ,72 h after treatment . To obtain the optimal ultrasound parameters ,the tumor inhibitory effect was assessed by enhanced intensity ( EI) and microvascular density ( MVD) . The H22 tumor were treated by ultrasound exposure nanobubbles combined with cisplatin to observe their tumor growth inhibition rate ,and the microvessels density and nuclear associated antigen Ki‐67 proliferation index were measured by immunohistochemical staining . Results There was a statistically difference in enhanced intensity (EI) between the experimental groups and control group ( P < 0 .05) . With the increasing of ultrasound intensity and exposure time ,the tumor inhibitory effect was more obvious ,with an increasing side reactions . Except the simple ultrasound group ,there was a statistical difference in tumor inhibition ,the mean MVD and the tumor cell proliferation index (KI‐67) between control group and the other ultrasound therapy groups ( P<0 .05) . The tumor inhibitory rate was the highest ( tumor inhibition rate 70 .0% ) and the mean MVD and KI‐67 expression were the lowest ( P <0 .05) in the combination group comparing with the others . Conclusions The ideal ultrasound exposure parameter of tumor inhibition showed that exposure intensity chose 1 W/cm2 and exposure time chose 1 min or 3 min intermittence . The ultrasound exposure self‐made nanobubbles combined with cisplatin could enhance the tumor inhibitory effect .Its mechanism may be related to the decrease of microvascular density ,the inbition of tumor cell proliferation and the increase of tumor cell necrosis .

Objective To discuss the influence of different ways of low-dose corticosteroids infusion on hemodynamics, changes in blood glucose level and prognosis in patients with refractory septic shock. Methods A prospective single-blind randomized controlled trial was conducted. Refractory septic shock patients admitted to the Department of Critical Care Medicine of Jiangxi Provincial People's Hospital from April 1st, 2013 to October 31st, 2014 were enrolled for the study. The patients were divided into control group and research group by random number table. Besides conventional treatment for septic shock, patients in control group were given 200 mg/d hydrocortisone intravenous infusion lasting for 2 hours, while those of research group were given 8.33 mg/h hydrocortisone per hour with an intravenous pump. Treatment lasted for 5 continuous days for both groups. The changes in heart rate ( HR ), mean arterial pressure ( MAP ), central venous pressure ( CVP ) and arterial blood lactic acid in both groups were observed at the time of enroldment and 6 hours, 24 hours, 48 hours, and 5 days after the treatment. With a dynamic blood glucose monitor, mean blood glucose ( MBG ) level, largest amplitude of glycemic excursions ( LAGE ), glucose variability ( GV ), and the ratio of hyperglycaemia time were recorded. The duration of shock, length of intensive care unit ( ICU ) stay, total length of hospital stay, and 28-day mortality of both groups were recorded. Results Seventy-nine septic shock patients were assigned to the treatment, with 41 in control group, and 38 in research group. Compared with control group, 6-hour MAP in research group was obviously lowered [ mmHg ( 1 mmHg=0.133 kPa ):66.31±4.38 vs. 68.58±4.86, t=1.062, P=0.033 ], but there were no significant differences in HR, MAP, CVP, lactic acid clearance and norepinephrine ( NE ) utilization rates at other time points between two groups. No significant difference in MBG was found between research group and control group ( mmol/L:8.69±2.14 vs. 9.95±3.87, t=1.771, P=0.080 ), but LAGE, GV, the ratio of hyperglycemia time in research group were significantly lower than those of the control group [ LAGE ( mmol/L ): 17.18±8.97 vs. 22.71±11.80, t = 2.331, P = 0.022; GV ( mmol/L ): 2.57±1.05 vs. 3.16±1.37, t=2.136, P=0.036;the ratio of hyperglycemia time:( 43.1±11.7 )%vs. ( 49.4±15.3 )%, t=2.044, P=0.044 ]. There was no statistical difference in the following features between research group and control group, such as the duration of shock ( days:3.47±0.98 vs. 3.61±1.07, t=0.605, P=0.547 ), length of ICU stay ( days:8.74±3.12 vs. 9.97±3.37, t = 1.543, P = 0.120 ), total length of hospital stay ( days: 18.34±9.27 vs. 19.58±9.83, t = 0.576, P = 0.566 ) and 28-day mortality rate ( 23.68%vs. 26.83%,χ2=0.103, P=0.748 ). Conclusions Compared with slow intravenous infusion, a continuous intravenous supplementation of small amount of hydrocortisone to patients with refractory septic shock could stabilize blood glucose levels and maintain metabolic balance efficiently. However, in both groups there was no significant difference in the efficiency in stabilizing hemodynamics, shortening shock duration, reducing ICU or hospital days and decreasing 28-day mortality.
