Stem cells offer considerable promise in the repair or replacement of damaged tissue in the body.Mature and functional endothelial cells play a pivotal role in neovascularization and maintenance of blood vessel integrity.Although being the best choice for transplantation endothelial,cells isolated from autologous vessels have been heavily obstacled in medical application due to poor resources and limitted proliferation potential in culture.Thus,stem cells have been the focus of the studies soareh for suitable cell sources.Several types of stem cells have been reported to possess endothelial cell differentiation potential.This article summarized the recent study on the sources,distribution,features-differentiation,animal experiments and clinical use of stem cells.Advantages and disadvantages are compared to provide a reference for the choice of evdothelial celia source.

Objective To assess the impact of tranexamic acid on visible and hidden blood loss after the preliminary unilateral total hip arthtoplasty (THA).Methods The study involved 60 patients who received primary unilateral THA due to femoral neck fracture from March 2010 to September 2011.They were 18 males and 42 females,at 58 to 86 years of age (average 74.5 years).They were divided into Group A (n =20),not given tranexamic acid,Group B (n =20),given tranexamic acid in operation,Group C (n =20),given tranexamic acid at preoperative one hour according to stratified random method.Total red blood cell loss,visible red blood cell loss,and hidden red blood cell loss in each group were calculated.Results Visible red blood cell loss in Groups A,B,and C was (95.4 ± 17.7) ml,(45.5 ± 11.5) rnl,and (45.3 ± 8.4) ml respectively.Moreover,difference of visible red blood cell loss was significant between Groups A and B (P ＜ 0.05),but insignificant between Groups B and C (P ＞ 0.05).Hidden red blood cell loss in Groups A,B,and C was (322.4 ± 57.7) ml,(203.8 ±46.6) ml,and (137.6 ± 34.7) ml respectively,with significant difference between Groups A and B (P＜0.05) and between Groups B and C (P＜0.05).Conclusions Tranexamic acid reduces the visible and hidden blood loss in primary unilateral THA significantly.While tranexamic acid administered at preoperative one hour gains advantage of less hidden blood loss over the intraoperative administration.

BACKGROUND:Currently, cosmetic liposuction has developed rapidly, but the liposuction for the isolation of adipose-derived stem cells has not been reported.
OBJECTIVE:By evaluating the quantity and viability of stromal vascular fraction, adipocytes and adipose-derived stem cells obtained from different types of liposuctions, to find the advanced liposuction procedures that are most suitable for use in preparation, preservation and clinical application of adipose-derived stem cells.
METHODS:Authors retrieved PubMed database, NIH clinical trial databaseand CNKI ful text database for relevant articles using the key words of“adipose-derived stem cells, ADSCs, liposuction, SAL, UAL, PAL, WAL”in English and Chinese, respectively. After eliminating the objective-independent articles and repeating reviews, 50 papers were included for further analysis.
RESULTS AND CONCLUSION:Suction-assisted liposuction (SAL), ultrasound-assisted liposuction (UAL), power-assisted liposuction (PAL) and water-assisted liposuction (WAL) are four major types of fat-harvesting technologies that can possibly be applied for adipose-derived stem cells isolation. Accumulative evidence suggests that these advanced liposuctions can obtain high quality of adipose tissue/cells, which are good enough for autologous fat grafting. Adipose-derived stem cells that are isolated from lipoaspirate by WAL, SAL and UAL, can be used as autologous cel-assisted lipotransfer and regenerative therapy. In summary, although each of these four types of liposuction technologies has its own advantages and is feasible to be used as autologous fat grafting, systematic comparative studies for viability, chromosome stability and differentiation potentials of adipose-derived stem cells isolated using each col ecting method are necessary in order to confirm the future perspectives in adipose-derived stem cells isolation, banking and regenerative repair.

Multidrug resistance (MDR) is a major impediment to the success of cancer chemotherapy. Multidrug resistance-associated proteins (MRPs) play an important role in the process of MDR. As an ATP-binding cassette (ABC) transporter superfamily, MRPs are selective and specific drug efflux pumps. In this paper, physiological characteristics, structural characteristics and resistance profile of MRPs and the associated reversal studies are reviewed.

Objective To compare the effect of atropine sulphate and cyclopentolate hydrochloride in the treatment of youth hyperopia cycloplegic refraction,and provide the basis for a reasonable choice of the youth cycloplegic refraction drugs.Methods Ninety hyperopia children met inclusion criteria with refractive errors (180 eyes) were subjected to cycloplegic refratometry by 1％ cyclopentolate hydrochloride followed with 1％ atropine sulphate eye used gel.The refractive results,pupil size,residual adjustment amount and systemic side reactions were measured and compared by TOPCON.Results The coincidence rate of spherical lens degrees,cylinder lens degrees and axis of astigmatism degrees respectively was 84.44％ (152/180),92.78％ (167/180) and 92.78％ (167/180) between atropine sulphate and cyclopentolate hydrochloride.The spherical lens degrees of cyclopentolate hydrochloride was lower than atropine sulphate,the difference was statistically significant (P ＜0.01),the cylinder lens degrees and axis of astigmatism degrees had no significant difference between two drugs (P＞ 0.05).The pupil size and residual adjustment amount of cyclopentolate hydrochloride had no significant difference with atropine sulphate (P ＞ 0.05).The incidence of adverse reactions of cyclopentolate hydrochloride was 3.33％ (3/90),atropine sulphate was 13.33％ (12/90),the cyclopentolate hydrochloride was significantly lower than atropine sulphate (P ＜ 0.05).Conclusion The cyclopentolate hydrochloride has powerful,fast and secure feature in the treatment of youth hyperopia cycloplegic refraction,has good ciliary muscle paralysis effect,has longer paralysis time,as effective as the atropine sulphate,and has a shorter recovery time and better security,is ideal cycloplegic drugs for youth hyperopia cycloplegic refraction.
