Objective To observe the inhibition of different concentrations of curcumin on cell growth,and explore the molecular mechanism of curcumin on human osteosarcoma.Methods Curcumin of different concentrations(0,10,20 and 40?mol/L) was administered to U-2OS cells of human osteosarcoma for 12h,24h and 48h,respectively.The proliferation of U-2OS cells was measured by MTT assay.Results Curcumin significantly inhibited the proliferation of PC-3 cells in vitro in concentration-and time-dependent manners.The higher the concentration of curcumin,the stronger the inhibition was(10?mol/L,20?mol/L,40?mol/L of r=-0.9638,-0.9778 and-0.9764,respectively,P

Objective To investigate the hypothesis that food allergy in infants may be associated with variation in their intestinal microflora. The formation of intestinal microflora in healthy infants and changes in food allergic infants were detected.Methods 16S rRNA gene sequences specific for bifidobacterium, lactobacillus and escherichia coli in fecal were quantitatively detected by real-time PCR. The three fecal floras were assessed in 71 healthy infants and 100 infants with food allergy. Results After birth,there were bifidobacteria colonized in infantile intestine,then the number increased rapidly up to 5 times at the sixth month, which was always the preponderant flora. Lactobacilli was also presented in infantile intestine 1 month after birth and augment gradually. The number of Escherichia coli was less than bifidobacteria and lactobacilli and appeared to decline during the early infants. The number of bifidobacteria and lactobacilli in the infants with food allergy were markedly less than that in the healthy infants, but escherichia coli was significantly more than that in the healthy infants.Conclusions During the first year of life,the intestinal microflora in infants is in a developing process. Compared with the healthy infants,bifidobacteria and lactobacilli decrease, but escherichia coli increase in the food allergic infants.These results indicate that the probiotics may be benefit to the prevention and treatment of food allergy.

As a kind of mature non-invasive brain stimulation technology, transcranial direct current stimulation (tDCS) has shown sig-nificance in clinic. Recently, DCS has been applied over the scalp to the spinal cord, named transcutaneous spinal direct current stimulation (tsDCS), that may modulate the spinal cord tracts and spinal cord loop electrical activity at segmental level, and may benefit in the treatment of chronic pain and motor dysfunction after injury of nervous system. This paper reviewed physiological effects, safety considerations and potential clinical applications of tsDCS.

Mind map is an effective and intuitive knowledge organization and presentation tool which can help computer teaching commendably. We can use Mind Map to design and organize the whole teaching process, including preparing, designing, guiding, analyzing and reviewing. This way can turns tedious logic of computer teaching into imagery thinking and helps medical students improv-ing their learning effect of computer courses.

Objective To analysis the clinical characteristics of kidney transplantation for the aged recipients and the influence of quadruple immunosuppressant on treatment result. Methods From 1990 to 2001,of 1251 cases of renal transpantation,the clinical data of 126 cases of the aged recipients over 60 years old were investigated.The aged recipients was divided into two groups;combination of cyclosporine(CsA),azathoprine(Aza) and corticosterioids was given in groupⅠ,In groupⅡ,except for CsA,mycophenolate mofetil(MMF),corticosteroids and Wu-T 3 quadruple therapy in the 47 cases aged recipients, Daclizumab or Basiliximab were injected in prophylaxis of acute rejection within 2 hours prior to transplantation and in someday after transplantation to the 24 aged recipients. The groupⅡ was compared with the groupⅠ in complications, the rate of acute rejection and the one-year-survival rate of patients/allograft.Results The rates of cardiocerebral vascular disease and infection complications in the aged recipients were higher than that in the non-elderly patients. In the groupsⅠ and Ⅱ, the postoperative complications was 74 55%and 38 03%, respectively;the rates of acute rejection were 12 73% and 4 23%,respectively;one year survival rate of patients/allografts was 81 82%/78 18% and 97 18%/95 77% respectively.Conclusions The cardiocerebral vascular disease and infection complications were the main factors affecting the outcome of renal transplantation in the aged recipients. The quadruple immunosuppressant regimens could reduce postoperative complications and acute rejection. At the same time one-year-survival rate of patients/ allografts have been improved in the aged patients.

Objective To describe surgical nurses' learning motivation of attending continuing nursing education (CNE) and to analyze influencing factors of learning motivation.All of these would be reference for managers of hospitals and administrative department to improve the quality of CNE and make related policy.Methods 140 surgical nurses from one general hospital were recruited to fill a questionnaire of demographic data of participants and revised Education Participation Scale (EPS).Results The score of EPS of surgical nurses was (89.26±13.67),the first dimension was professional advancement,followed by serving society,learning interest,social relation,external expectations and escape/stimulation.The score of EPS of nurses who were younger than 35 years old,single,no administrative posts was higher than nurses who were older than 35 years old,married or in administrative position.Education level,working life,professional ritle,financial resources and numbers participating in CNE in recent 1 year made some differences for EPS score.Conclusions The score of EPS of surgical nurses was at middle level,factors affecting EPS were different.The managers should take interventions to improve the motivation of attending CNE according to nurses' characters in order to increase the professional level and nursing quality of nurses.

Objective To investigate the effect of multiple treatments on cystospasm after transurethral resection of prostate(TURP). Methods From 2006 to 2013, 663 patients who had received TURP for BPH were civided into 6 groups:2 were treated by kieselgel or lac-toprene urethral catheter,defined as catheter observe group. 2 were treated by warmed or ordinary temperature douche,defined as temperature observe group. 2 were treated by dicaine mixed or normal douche,defined as mixed douche observe group. The incidence rates and duration of cystospasm and visual analogue scores of pain were observed and the diversities were measured by statistics within each pair groups. Results The incidence rates and duration of cystospasm and visual analogue scores of pain of groups treated by kieselgel urethral catheter,warmed douche and dicaine mixed douche were obviously lower than the groups treated by lactoprene urethral catheter,ordinary temperature douche and normal douche. The kieselgel urethral catheter and warmed douche decreasing the irritation on mucous membrane of bladder,the dicaine decreasing the sensibility of bladder nerves may be the mechanism. Conclusion The incidence rates and duration of cystospasm and visual analogue scores of pain can be obviously decreased by treatments of kieselgel urethral catheter,warmed douche and dicaine mixed douche.
