Objective To determine whether chronic constriction injury (CCI) to sciatic nerve is associated with changes in the phosphorylation of CREB in dorsal root ganglia ( DRG) and superficial dorsal horn neurons of the spinal cord.Methods Thirty-two adult female SD rats weighing 230-270 g were randomly divided into 4 groups (n = 8 each): Ⅰ blank control;Ⅱ sham operation; Ⅲ CCI 2w and Ⅳ CCI 4w. The animals were anesthetized with intraperitoneal pentobarbital 40 mg?kg-1. Right sciatic nerve was exposed and 4 ligatures were placed on the right sciatic nerve at 1 mm interspace with 3-0 silk suture. Paw withdrawal threshold to mechanical stimulation (von Frey filament) applied to plantar surface ( MWT) and paw withdrawal latency to thermal stimulation (radiant heat) (TWL) were measured before operation (baseline) and 14 days (group Ⅰ,Ⅱ and Ⅲ) or 28 days (group Ⅳ) after nerve ligation. The animals were killed the next day and the L4,5 segment of the spinal cord and L5 dorsal root ganglion were removed for determination of expression of phosphorylated-CREB-immuno-reaction(pCREB-IR) using immuno-histochemistry. The pCREB-IR cells both in DRG and superficial dorsal horn neurons were quantified and analyzed. Results The animals developed mechanical and thermal hyperalgesia on the 14th day after CCI (in group CCI 2w) . The hyperalgesia was greatly attenuated on the 28th day after CCI. Interestingly enough the animals in sham operation group (Ⅱ) also developed mechanical hyperalgesia to some extent on the 14th day after operation. The number of pCREB-IR cells was significantly increased in the ipsilateral L5 DRG and superficial dorsal horn in group Ⅲ(CCI 2w) as compared to sham operation group ( P

Objective To investigate the effect of parthenolide (PN) on human colon cancer cells in vitro and its mechanism. Methods Human colon cancer cell line HT-29 was cultured and treated with PN at the concentra-tions of 10 ,50 ,100 ,200,500 ,1 000 μmol/L for 48 hours. Then the apoptosis was detected by flow cytometry. The ex-pression of NF-Κb p50 and COX-2 proteins were analyzed by Western blot and the concentration of PGE2 was meas-ured with ELISA kits. Results PN significantly induced cell apoptosis after 48 h in a dose-dependent manner. The expression of NF-Κb p50 and COX-2 proteins were down-regulated by the PN, and the concentrations of PGE2 were al-so declined. Conclusion PN can induce apoptosis of the human colon cancer cells. And the process may be carried out through the way of "NF-Κb→COX-2→PGE2".

Objective To evaluate clinical value of ultrasound contrast agent the sulfur hexafluoride micro-bubble in the treatment of T2WI high signal uterine fibroids with high intensity focused ultrasound (HIFU).Methods A total of 36 patients with T2WI high signal uterine fibroids were randomly divided into experimental group and control group.Eighteen patients in experimental group received HIFU treatment with sulfur hexafluoride micro-bubble before,during and after the operation while another eighteen in control group received HIFU treatment with sulfur hexafluoride micro-bubble only after the operation.We recorded operation time (min),changing time of massive gray (s),irradiation time (s),therapeutic dose (J),incidence of complications and ablation rate (％).Results Operation time,changing time of massive gray,irradiation time,and therapeutic dose in experimental group were (101.51±43.02) min,(856.42±451.14) s,(1077.37±546.23) s,and (496581.81 ± 267192.31) J,respectively while those in control group were (261.34 ± 85.53) min,(1 833.32 ± 642.67) s,(1 890.21 ± 1 268.43) s,and (784 608.31 ± 357 621.45) J,respectively.Significant differences were found among those parameters between the two groups (P ＜0.05).Tumor ablation rate in experimental group was 83.3％ while that in control group was 55.5％,which was of significant difference between the two groups (P＜0.05).One case of muscular stiffness was found in experimental group while one case of second-degree burn and two cases of muscular stiffness were found in the control group.The incidence of complications was 1/18 (5.5％).No severe complication like bowel perforation or bladder perforation was found in the two groups.Conclusion The effect of ultrasound contrast agent sulfur hexafluoride micro-bubble can shorten operation time,improve tumor ablation rate and reduce complications and it can play a guiding role in clinical work.

Objective To study factors influencing injury severity of expressway traffic acci- dents. Methods Data of expressway traffic accidents involving casualties in areas around Hangzhou during 2005-2006 were collected and analyzed by non-conditional simple and multiple logistic regression analysis. Results (1) During 2005-2006, there were 220 traffic crashes involving 327 eases, of which there were 64 deaths (19.6%), 121 severe injuries (37.0%, ISS≥16 points) and 142 slight and mod- erate injuries (43.4%, 1 point≤ ISS≤15 points). (2) Non-conditional simple logistic regression analy- sis showed that risk factors significantly influencing the injury outcomes of traffic accidents included gen- der, weekday, weather, type of collision, vehicle type, driver category, purpose of vehicle use, purpose of travel and crash responsibility. (3) Non-conditional multiple logistic regression analysis manifested that influential factors were gender, type of collision, driver category and crash respensibihty. Conclu- sion Analysis of expressway traffic accidents data helps identify factors influencing injury severity of ex- pressway traffic accidents may provide suggestions for prevention or decrease of expressway traffic acci- dents.
