Trypanosoma is a human parasite severely affecting poor tropical areas.However,current frontline drugs for Trypanosoma treatment have severe side-effects with decreased effectiveness.Based on the fact that aminoacyl-tRNA synthetase is a bonafide drug target for several microorganisms,including bacteria and fungi,it is plausible that it may also be effective target of Trypanosoma.The Trypanosoma brucei leucyl-tRNA synthetase(tbLeuRS)was cloned,expressed and purified to develop an in vitro enzymatic assay system.The assay conditions were further optimized for the effective screening of tbLeuRS inhibitors thus establishing an anti-Trypanosoma drug screening system targeting tbLeuRS.The results indicated that this system can be employed for the effective screening of anti-Trypanosoma drugs with satisfactory specificity.In addition,this system can also be used for compound optimization,as well as IC50 testing.Using this system a series of compounds are identified that are effective Trypanosoma inhibitors without toxicity to human cells.Therefore,targeting tbLeuRS may represent a new venue for the development of anti-Trypanosoma drugs.

ObjectiveTo investigate and compare the efficacy, safety, and cost effectiveness in the treatment of painful osteoporotic vertebral compression fractures ( OVCFs ) with percutaneous vertebroplasty (PVP) and kyphoplasty(PKP). MethodsSeventy-two patients (96 vertebrae) with painful OVCFs were treated by PVP (n =34) or PKP (n =38) under radiological monitoring. After bone biopsy needle into the compressed vertebra, bone cement (polymethylmethacrylate) was injected in PVP group, and that was inserted followed by the inflation of vertebra to create cavities in PKP group. The fluoroscopy time, total amount of bone cement injected, and cost were recollected respectively. The score of visual analogue scale point( VAS, 10-point scale)was determined at before the procedures, and 24 hours, one week, and one month after the procedures.Pain relief and complications were observed.The Cobb angle and vertebral heights of the anterior, middle, and posterior border were measured pre-and post-operative. ResultsThe two procedures were technically successful in all patients. The follow-up ranged from 1. 0 to 34. 0 months [mean time, (8. 9 ±3.2) months]. The Mean fluoroscopy time of treating per vertebra in PVP group was ( 11. 1 ± 10. 6 ) min, which was significant shorter than that ( 23.5 ± 13. 0) min in PKP group( P <0. 05 ).The mean total cost per patient was (5127. 2 ± 502.3 ) yuan in PVP group, which were strikingly lower than that(32 301.4 ±3204. 6) yuan in PKP group (P <0. 05).(3)There was no significant difference( P >0. 05 ) in average cement volumes in PVP group [ (4. 9 ± 1.1 ) ml]and PKP group [ (5.4 ± 1.7 ) ml]. Pain relief of was observed in 94. 1% (32/34) of PVP group and in 92. 1% (35/38) of PKP group. The score of VAS at pre-operation was (8. 3 ±0. 4 vs 7.9 ±0. 8) ,and at post-operative 24 h (2. 9 ±0. 9 vs 2. 8 ± 1. 2),1 week (2.6 ± 0. 9 vs 2.6 ± 1. 1 ), and 1 month (2.6 ± 0. 9 vs 2. 5 ± 1.3 ) were no difference at PKP and PVP group(P <0.05). There was significant difference between pre- and post-operative time point in each group. The Cobb angle, anterior and middle height of vertebra was corrected in both PVP and PKP group. In PVP group, the preoperative Cobb angle, anterior and middle height of vertebra was (24. 2 ± 3.8 )°,( 19. 1 ± 1.4) mm, (25. 2 ± 1.0) mm, which was significant different ( P < 0. 05 ) from that of ( 19.4 ±3.9)°, (21.0 ± 1.5) mm, (27.0 ± 1.2) mm at pre-operation.In PKP group,there was significant difference (P < 0. 05 ) in the preoperative Cobb angle, anterior and middle height of vertebra [(25. 1 ±5.0)°vs(10.7 ±2.8)°, (19.5 ± 1.5) mm vs (24.3 ± 1.9) mm, (25.4 ± 1.1) mm vs (29.7 ±1.3) mm, respectively]. As to the above index, the overall correcting effect in PKP was much better than that in PVP( P <0. 05 ). Cement leakage occurred in 9 cases in PVP group and 3 cases in PKP group ( P <0. 05 ) but no symptoms. There were no major complications during operation in the two groups. Conclusion PVP and PKP are effective and safe in the treatment of painful OVCFs but PVP is more cost effective than PKP.

OBJECTIVETo evaluate the clinical significance of umbilical activin A in preterm infants.
METHODSForty-one preterm infants (gestation 28 to 36 weeks) were enrolled. Fetal membranes, umbilical cords and blood samples from umbilical vein were obtained. Umbilical activin A level was measured using ELISA. The histological examinations of fetal membranes and umbilical cords were performed.
RESULTSThe umbilical level of activin A averaged 2069 pg/mL in the 41 preterm infants. The umbilical activin A level in the 5 infants with intrauterine infection was higher than in those without intrauterine infection (2510 pg/mL vs 1975 pg/mL; P<0.01). Umbilical activin A level at cutoff of 2490 pg/mL showed a sensitivity of 80.0% and a specificity of 90.6% as a marker of intrauterine infection. There were no significant differences in the umbilical activin A level between the infants with and without respiratory distress syndrome. Umbilical activin A level was positively correlated with the duration of postnatal oxygen therapy (r=0.326, P<0.05).
CONCLUSIONSUmbilical activin A may serve a marker of intrauterine infection in preterm infants. The umbilical activin A level is correlated with the duration of postnatal oxygen therapy.

Objective To discuss the optimal retrieval time of the indwelling Gunther Tulip and Cook Celcet inferior vena cava filters (VCF). Methods During the period from March 2013 to April 2015 at Shengli Oilfield Central Hospital, the implantation of retrievable inferior vena cava filter was performed in 58 patients. Among the 58 patients, Gunther Tulip VCF was used in 13 and Cook Celcet VCF was employed in 31. Twenty-one patients followed the doctor's advice to receive retrieval procedure of VCF within three months after the implantation. Results Among the 21 patients, successful retrieval of VCF was obtained in 19. The mean indwelling time of Gunther Tulip VCF was 54.4 days, the longest time being 79.0 days. Gunther Tulip VCF was successfully removed in 3 patients and retrieval of VCF failed in 2 patients, with a retrieval success rate of 60%. The mean indwelling time of Cook Celcet VCF was 37.6 days, the longest time being 67.0 days. Cook Celcet VCF was successfully removed in 16 patients, with the success rate of retrieval being 100%. Conclusion Despite many VCFs that have been indwelled for a long time can be safely retrieved, retrieval procedure should be performed as early as possible in order to improve the retrieval success rate of VCF. It seems that the use of Cook Celcet VCF is a better choice although it is more expensive.
