1.Research progresses of tumor inhibiting protein p33ING1b in the tumors of digestive system
Practical Oncology Journal 2015;(3):254-258
Tumor inhibiting protein p33ING1b is the key expressive product of inhibitor of growth 1.It plays critical role in cell multiplication ,period control ,senescence ,repair of DNA damage ,apoptosis ,and chroma-tin remodeling.The abnormal expression of p33ING1b is closely related to the occurrence and development of tumor.This paper reviews tumor inhibiting protein p 33ING1b in the research development of tumors in digestive system.

Objective To investigate analgesic effects of flurbiprofen in lower extremity liposuction for patients with primary lymphedema. Methods A total of 60 patients receiving lower extremity liposuction under general anesthesia were allocated to 3 groups:the control group (group A) received no analgesic drug 10-20 min before the end of operation, the parecoxib group (group B) received intravenous parecoxib 40 mg, and the flurbiprofen group (group C) received intravenous flurbiprofen 100 mg.The VAS was recorded at 1, 2, 6, 12, and 24 h after operation.Adverse reactions were also recorded . Results The VAS of rest pain and motion pain at 1, 2, 6, and 12 h were significantly lower in the group B than those in the group A (P<0.05);the VAS of rest pain and motion pain at 1, 2, and 12 h were significantly lower in the group C than those in the group A (P<0.05).The VAS at 1 and 2 h did not differ between the group B and C (P>0.05), but had significant difference at 6 and 12 h (P<0.05).No significant differences in the VAS at 24 h were observed among the three groups (P>0.05).Adverse reactions were not different among the three groups (P>0.05). Conclusion Both flurbiprofen and parecoxib sodium can achieve good postoperative analgesic effects in patients with lymphedema receiving lower extremity liposuction .

Objective To establish a method for the determination of naringin in Gongning Granule, Methods The sample was extracted with methyl and the chromatographic conditions were as follows: Kromasil C18 chromatographic column(250 mm?4.6 mm ,5 ?m)with a mobile phase of methyl and 1 %acetic acid (35.5 ∶64.5),the detection wavelength at 283 nm and the flow rate being 1.0mL?min-1. Results A linearity of naringin in Gongning Granule was obtained in the range of 0.0980 ?g to 0.980 ?g,r=0.9997 (n=6).The average recovery was 98.7 %and RSD=1.96 %(n=6). Conclusion This method is easy,sensitive and accurate for the determination of naringin in Gongning Granule.
