OBJECTIVETo examine the effect of ONO-AE3-208, an EP4 antagonist, on the formation of bone metastasis from prostate cancer in mice.

METHODSThirty-four 6-week old nude mice were divided into an experimental and a control group of equal number to be treated by intraperitoneal injection of ONO-AE3-208 and double distilled water, respectively. Then PC3/LUC cells were constructed by stably transfecting luciferin to prostate cancer PC3 cells and inoculated into the left ventricle of the mice to establish an animal model of systemic bone metastasis. The time of metastasis formation, photon tumor burdens, and changes of the survival curves after modeling were compared between the two groups of mice.

RESULTSAt 30 days after modeling, bioluminescence imaging analysis showed that the photon tumor burdens were significantly increased in a time-dependent manner in the control group in comparison with those in the experimental group (P < 0.01). The rate of metastasis formation was significantly higher in the former than in the latter (93.3% vs 33.3%, P < 0.001). The median time of metastasis formation was 29 d (95% CI 26.547 - 35.262) in the experimental animals as compared with 21 d (95% CI 17.213 -24.787) in the controls (P < 0.001).

CONCLUSIONEP4 antagonist ONO-AE3-208 can inhibit the formation of bone metastasis from prostate cancer in mice.

Objective To study the clinical value of short term variation(STV)of fetal heart rate. Methods Three hundred thirty-eight pregnant women who delivered at our hospital during June 2002 and Dee 2005 were studied.All the eases were examined by non-stress test(NST)and vibratory acoustic stimulation test(VAST).Meanwhile,they were also analyzed by Sonieaid system 8002.One hundred fifty cases with STV≥5.0 ms as control group,and 188 cases with STV

Objective To investigate the potential relationship between initial 131Ⅰ uptake by lung metastases from differentiated thyroid cancer (DTC) and treatment outcomes. Methods From 1997 to 2009, 41 patients with DTC lung metastases were treated in the authors' department. 131Ⅰ whole body scan (WBS), serum Tg levels and other imaging results were analyzed to evaluate the therapeutic effects. Complete response (CR) or partial response (PR) was considered to be effective. The x2 test and correlation analysis were performed using SPSS 11.5 software package. Results 131 Ⅰ treatment was effective in 63% (26/41) patients with DTC lung metastases, CR in 8 patients and PR in 18 patients. In other 37% ( 15/41 ) patients, 131Ⅰ treatment was ineffective, including one case died of distant metastases. Patients with initial presence of 131Ⅰ lung uptake had higher effective rate than those with 131Ⅰ lung uptake during the second or later 131Ⅰ treatment (76% (22/29)vs33% (4/12),x2 =4.911, P=0.027). Also, significantly higher effective rate was found in patients with lung metastases alone than those with extra-pulmonary metastases (75% (24/32) vs 22% (2/9), x2 = 6. 312, P =0.012). However, the effective rate in patients with diffuse metastases was not significantly different from that in patients with focal metastases (67% (12/18)vs 61% ( 14/23), x2 =0. 146, P=0.702). The positive rate of initial 131Ⅰ uptake by lung metastases was higher in patients with total thyroidectomy than those with partial thyroidectomy (83% (24/29) vs 42% (5/12) ). Those positive rates in patients with papilary DTC and patients with follicular DTC were 72% (23/32) and 6/9, respectively. The surgical mode was correlated with the initial 131Ⅰ uptake by lung metastases (r = 0.411, P ＜ 0.05), but no correlation was found between the histological type and the initial 131Ⅰ uptake by lung metastases ( r = 0. 047, P ＞ 0.05 ). Conclusion Initial uptake of 131 Ⅰ by lung metastases alone is a favorable prognostic factor for DTC patients treated by131Ⅰ, and total thyroidectomy may be beneficial for initial 131Ⅰ uptake by lung metastases.

Background Oxidative stress is thought to be responsible to diabetes-complicated cataract.Our previous study demonstrated that as an iron chelator,deferiprone can protect lens from oxidative damage.Objective This further study aimed to investigate the role of deferiprone on the formation of diabetic-complicated cataract.Methods Forty 6-week-old Wistar rats were included in the study and randomized into 4 groups.Eight of them were used as the normal control group.Diabetes mellitus animal models were established in 22 rats by the carbonhydratediet and fat diet and the intraperitoneal injection of 40 mg/kg streptozocin (STZ).The deferiprone of 50 mg and 100 mg were intragastrically given in 8 model rats respectively after 3 days once a day for 8 weeks.The opacification of lenses was examined under the slit lamp weekly after treatment.The animals were sacrificed and the lenses were obtained at the eighth week of deferiprone injection.The concentrations of water-soluble protein ( WSP),urine-soluble protein (USP) and alkali-soluble protein (ASP) in rat lens suspension were detected by Bradford method.The super oxide dimutese (SOD),malondialdehyde (MDA) and glutathione (GSH) were determined spectrometically using xanthine oxidase,thiobarbituric acid,dithio bis-nitrobenzoic acid.Results No evidently differences were found in the content of the WSP,USP and ASP among the these groups( F=1.73,0.18,0.09,P＞0.05).The contents of MDA in 50 mg deferiprone group and 100 mg deferiprone group were ( 1.05 ± 0.10 ) mmol/g and ( 1.05 ± 0.22 ) mmol/g respectively,showing a significant decline in comparison with diabetic model group (P＜0.05).The SOD and GSH contents in lens were (321.29±16.57) U/mg,(322.07±22.16) U/mg and (7.83±0.65 ) mg/g,(7.70±0.77 ) mg/g respectively in 50 mg deferiprone group and 100 mg deferiprone group and were considerably elevated in comparison with ( 298.70± 14.69 ) U/mg and ( 5.47 ± 1.01 ) mg/g of diabetic model groups ( P＜0.05 ).No significant differences were found in the indexes mentioned above between 50 mg and 100 mg deferiprone groups(P＞0.05).Conclusions Deferiprone can reduce oxidative stress and improve the energy metabolism of the lens in diabetic rats.

OBJECTIVE:To study the anti-inflammatory effect of Xinfeng capsule on adjuvant arthritis (AA) in rats. METH-ODS:70 SD rats were randomized into a normal control group(isovolumetric normal saline),a model control group(isovolumet-ric normal saline),a positive control TCM group [Qufeng zhitong capsule 0.4 g(crude drug)/kg],a positive control chemical medi-cine group(Leflunomide tablet 2.1 mg/kg)and groups of low,middle and high doses of Xinfeng capsule,which were respectively marked as groups A,B,C,D,E,F and G. All groups of rats except for Group A were given freund’s complete adjuvant intracu-taneous injection to establishe AA models,and from the 12th day after the inflammation was induced,were given the correspond-ing drug,ig,for 28 consecutive days. The degree of toe swelling and arthritis index were determined and calculated for all groups of rats before and after the administration. The contents of interleukin 1β(IL-1β) and tumor necrosis factor α(TNF-α) in serum and synovial membrane of all groups of rats were determined 24 h after the last administration,and pathomorphological changes of their ankles were observed by light microscope. RESULTS:Compared to group A,group B demonstrated higher degree of toe swelling,arthritis index and contents of IL-1β and TNF-α in serum and synovial membrane,with statistical significance(P<0.01). After the administration,the degree of toe swelling and arthritis index of groups C,D,E,F and G reduced,with statistical signifi-cance(P<0.05). Compared to group B,groups C,D,E,F and G showed lower degree of toe swelling,arthritis index and con-tents of IL-1β and TNF-α in serum and synovial membrane,with statistical significance(P<0.01 or P<0.05). Synovial membrane hyperplasia and inflammatory cell infiltration were noted in the ankle tissue of the rats in group B,and such symptoms were not so serious in groups C,D,F and G. CONCLUSIONS:Xinfeng capsule has anti-inflammatory effect for AA rats by a mechanism which may be related to accelerating synoviocyte apoptosis and inhibiting synovial membrane hyperplasia.

Background It is well known that diabetic retinopathy(DR) involves in complex pathogenesis.Worse outcome of brain ischemia with hyperglycemia is mediated by mitogen-activated protein kinases (MAPK).However,the effect of phosphorylation of MAPK signal pathway on DR needs further investigation.Objective This study was to explore the the possible role of extracellular signal-regulated kinase1/2(ERK1/2)in DR.Methods Sixty SPF SD rats aged 8-weeks were grouped into the control group and diabetes group.Diabetic models were established by intraperitoneal injection of streptozotocin (STZ) (60 mg/kg) dissolved in citric acid buffer.Blood glucose level was more than 16.7 mmol/L were used as the diabetic group.The equivalent amount of citric acid buffer was injected in the same way in the rats of the control group.The rats were sacrificed and retinas were isolated in 4 weeks and 12 weeks after modeling.The morphology of rat retinas was examined by hematoxylin and eosin staining.The relative expression levels of phosphorylated-ERK1/2 and glial fibrillary acidic protein (GFAP)(absorption,A value) in rat retinas were detected by immunohistochemistry.Results Blood glucose levels of rats were significantly higher than those in the diabetic group compared with the control group at both 4 and 12 weeks after modeling(t=14.174,13.771,both at P＜0.05).In addition,the body weight was significantly lower and the drinking was much more in the rats of the diabetic group in comparison with the control group in 12 weeks(t=8.670,18.725,both at P＜0.05).Twelve weeks after modeling,the decrease of retinal thickness,swelling of outer plexiform layer and decline of number of retinal ganglion cells,rods and cones were seen under the optical microscope.The relative expression levels of GFAP in the retinas were 3 197.1 ±13.1 and 7 202.0±56.8 in the diabetic group at the 4 and 12 weeks,which were significantly higher than those in the control group (2 152.8 ± 16.1 and 2 337.0±8.6) (t =6.327,16.417,both at P＜0.05).In 12 weeks after modeling,the relative expression level of phosphorylated-ERK 1/2 was significantly higher in the diabetic group compared with the control group (2 850.6±2.4 versus 1 274.6± 1.3),showing a significant difference between them (t =12.771,P ＜ 0.05).Conclusions Phosphorylation of ERK1/2 signal transduction pathway is involved in the STZ-induced DR through mediating the activation of Müller cells and inducing the apoptosis of photoreceptor and ganglione cells.

Objective To assess the effectiveness of the combined treatment model for Wilms'tumor and to improve treatment results.Methods Fifty-five patients diagnosed with Wilms' tumor between July 1981 to June 2010 were analyzed retrospectively.Eighteen patients were diagnosed by preoperative ultrasound-guided fine needle biopsy,and 53 patients were confirmed by postoperative pathology results.Seven cases were in clinical stage Ⅰ,19 cases in clinical stage Ⅱ,21 cases in stage Ⅲ,six cases in stage Ⅳ and two cases in stage Ⅴ.Thirty-five cases had histopathological subtype,30 cases had the favorable type,and five cases had the unfavorable type.Among the 55 patients,kidney tumor resection was performed on 48 cases,wide edge partial nephrectomy was performed on two cases,tumor enucleation was performed on one bilateral renal tumor case,kidney tumor resection with pulmonary metastasectomy was performed on two cases,and two cases had no surgical procedures.Eighteen cases received preoperative chemotherapy,40 cases received postoperative chemotherapy,and 12 cases received postoperative radiotherapy.Patients were grouped according to age,stage,histological type,treatment model,treatment course and whether or not they had radiotherapy.The Kaplan-Meier method was used in the evaluation and comparison of over survival (OS),disease free survival (DFS) and relapse free survival (RFS) of the different groups to reveal the relationship between different grouping factors with the prognosis of Wilms' tumor. ResultsThe median of follow-up was 34 mon ( ranging from 3 to 355 mon).The 3-year OS,5-year OS and 2-year DFS were 77.6％,69.0％ and 52.4％,respectively.The differences of OS in different stages ( P =0.006 ),DFS between pure operation group and combined therapy group ( P =0.004 ) and RFS between radiotherapy group and no radiotherapy group ( P =0.03 ) were significant,P ＜ 0.05.ConclusionsThe normative multi-disciplinary treatment model for patients with Wilms' tumor can achieve good results and is well tolerated.
