Objective To investigate the effect of ifenprodil in the mice of bone cancer pain.Methods 96 male C3H/HeJ mice were divided randomly into tumor group( Group T),control group( Group C) and sham group( Group S).The α-minimal essence media(ct-MEM) with 2 × l05 osteosarcoma NCTC 2472 cells were implanted into the intramedullary space of the right femurs of mice to induce ongoing bone cancer related pain behaviors.The sham group was inoculated by α-MEM without any cells.On the 14th d after inoculation,pain ethology indexes such as the spontaneous lifting behaviors,the paw withdrawal mechanical threshold(PWMT) and the paw withdrawal thermal latency (PWTL)were observed on 1 d before inoculation and on 3 d,5 d,7 d,10 d,14 d,17 d,19 d,23 d after inoculation.Lumbar intumescentia of mice in each group were taken out to investigate the expression level of NR2B western blot after pain behaviors tests at the same time point after intrathecal injection.Results ( 1 ) At day14 after the operation,the obvious increasing of spontaneous lifting behaviors ( ( 12.88 ±1.64) ) and the expression of NR2B (2.12 ±0.13),the significant decreasing of PWMT( (0.39 ±0.17)g) and PWTL( ( 11.59 ± 1.67 ) s ) were observed in group T compared with group S and preoperative base level (P ＜ 0.05 ).(2) At day 17,day 19 and day 23 after the operation,compared with the basal level of dayl4 before administration and group C,the spontaneous lifting behaviors ( (5.13 ± 1.38),(4.70 ± 1.58),(5.64 ± 1.17) ) of group T were obviously decreased,PWMT ( ( 1.10 ± 0.65 ) g,( 0.95 ± 0.56 ) g,( 1.05 ± 0.26 ) g) and PWTL ( ( 15.17 ± 1.27) s,( 15.93 ± 2.18 ) s,( 16.28 ± 1.48 ) s ) were increased,the expression of NR2B ( ( 1.42 ± 0.17),(1.67 ±0.53),(1.14 ±0.79) ) were significantly decreased(P＜0.05).Conclusion Repeated intratheal injection of ifenprodil can efficiently relieve spontaneous lifting behaviors,mechanical hyperalgia and thermal hyperalgia and decrease the expression of lumbar intumescentia NR2B in the mouse model of bone cancer pain.

ObjectiveTo investigate the effect of KN93,a CaMKII inhibitor,on the spinal NR2B expression in the bone cancer pain mouse and its underlying mechanism.MethodsThirty-six male C3IL/IIeJ mice were randomly divided into 3 groups:sham group( S,n =8 ),bone cancer pain group( BP,n =8 ) and KN93 group ( K,n=20).The mouse model of bone cancer pain was established by intra-femur inoculation of osteolytie NCTC 2472 cells in BP and K groups.At 14d post operation,mice in K group received intrathecal injection of 60nmol KN93/5μl in 20％ DMSO and mice in BP group and S group received 20％ DMSD 5μl respectively.Eight mice were selected randomly from each group at (1)d before inoculation,at 1 h before administration and at 1,2,4,24h after administration( T0-5 ) to be measured the paw withdrawal threshold(PWT) stimulated by von Frey filaments.Another 3 mice were sacrificed at the corresponding time point and the spinal cord L3 -5 were obtained for determination of NR2B expression by western blot.ResultsPWT was significantly decreased in group BP( (0.50 ± 0.11 ) g) and K( (0.52 ±0.10)g),except for group K at T3(P＞0.05),and NR2B cxpression up-regulated at T2-5 in BP( 1.78± 0.34),K groups ( ( 1.11 ± 0.14),(0.73 ± 0.03 ),( 1.11 ± 0.15 ),( 1.89 ± 0.32 ) ) compared with S group ( ( 1.78 ± 0.31 ) g,(0.33 ± 0.04),P ＜ 0.05 ).Compared with group BP,PWT was increased and NR2B expression down-regulated at T2-4 in group K.In contrast to T1,PWT at T2-4 upgraded in group K(P＜0.05 ),but no significant difference was observed in other groups (P＞ 0.05 ).ConclusionIntrathecal injection of KN93 can attenuate bone cancer pain in mice through inhibiting NR2B with a time-dependent manner and spinal CaMKII-NR2B pathway may participate in the development of bone cancer pain.

Objective To analyze the efficacy,late complications and prognostic factors of post-op-erative radiotherapy for cervical cancer. Methods From Nov. 1999 to Feb. 2005,114 patients with cervi-cal cancer received adjuvant pelvic radiotherapy after radical hysterectomy and pelvic lymphadenectomy. The median age was 42.5 (24 to 72) years old. According to the FIGO staging system,6,51,18,26 and 13 pa-tients had stage ⅠA, Ⅰb1, Ⅰb2, ⅡA and ⅡBdisease. The pathological type was squamous cell carcinoma,ade-nocarcinoma, squamous-adenocarcinoma and undifferentiated carcinoma in 92,19,2 and 1 patients, respec-tively. The whole-pelvic external beam irradiation of 50 Gy (40 to 60 Gy) was given with 6 MV or 15 MV X-ray beams using four-field box technique. Eighty-one patients received intravaginal brachytherapy of 16 Gy (4 -30 Gy in 1 -6 fractions) 4 weeks after the beginning of radiotherapy, with the referrence point being at 0.5 cm under the vaginal mucosa. Eighty-seven patients received preoperative and/or concurrent chemother-apy. The survival and independent prognostic factors were analyzed by Log-rank method and Cox model. Results The median follow-up time was 26.0 (5 - 75) months. The overall survival rate, disease-free sur-rival rate and local control rate were 93.1%, 88.1% and 94.6% at 2-year, and 75.7%, 62.3% and 85.6% at 5-year,respectively. The independent prognostic factors were lymph node metastasis and positive surgical margin for overall survival, positive surgical margin for local control, and stage, uterine body invasion and positive surgical margin for disease-free survival. Sixteen patients ( 14% ) had distant metastasis, and the most common sites were the lung,inguinal region,bone,liver and brain. According to RTOG grading sys-tem, the incidence of late gastrointestinal side effects of grade 1,2 and 3 was 11.4%, 11.4% and 3.5%. The corresponding genitourinary side effects were 14.0% ,6.1% and 0.9%, respectively. The incidence of leg lymphedema was 7 % . Conclusions Post - operative radiotherapy can achieve good local control in cervical cancer with acceptable late side effects. Distant metastasis is the main cause of death.

To observe the reliability and short-term and mid-term efficacy of a new designed multi-functional lacrimal sac nasal drainage stent on the treatment of nasolacrimal duct obstruction after endonasal endoscopic dacryocystorhinostomy ( EES-DCR ) , and to evaluate its clinical application value. METHODS: A retrospective case series study was carried out. Seventy - six patients ( 79 eyes ) with nasolacrimal duct obstruction underwent EES-DCR and a new type of multi-functional lacrimal sac nasal drainage stent was implanted. The nasal lacrimal drainage stent was pulled out 2~3mo later after surgery and the patients received 3~6mo follow-up afterwards. RESULTS: ln 79 eyes, stents were successfully implanted in 77 eyes (97. 5%). All stents of 77 eyes could be pulled out successfully 2 ~ 3mo after the operation. Sixty eyes were cured with unobstructed lacrimal irrigation and symptom of epiphora disappeared;15 eyes were improved of epiphora and mild reflux during lacrimal irrigation were found, overall effective rate was 97. 4%, 2 eyes failed in stent implantation. ln 6mo follow-up, nocomplications such as stent displacement or slip was occurred, the epithelization of anastomotic stoma was good.CONCLUSlON: Surgical technique of using the multi-function nasolacrimal stent is simple and fast, and implantation of the new designed stents has a rapid recovery with fewer complications. The usage of the new stents not only improves the success rate but also broadens surgical indications of EES-DCR, it is a safe and effective method for the treatment of nasolacrimal duct obstruction.
