Objective To establish a stable transplanted model of Vx 2 carcinoma in rabbit from three different transplanted methods, and analyze the DSA (digital substraction angiography) features of the implanted tumors. Methods 60 white rabbits of New Zealand were divided into 3 groups at random, 20 for each group. In the first group, Vx 2 carcinoma cells (about 5?10 7 )were infused via hepatic artery into the rabbit liver. For the second group, Vx 2 carcinoma cells (about 5?10 7 ) were inplanted into the left lobe of the liver via laparotomic route and in the 3rd group with the same route as the 2nd group, a piece of tumor tissue (contained about 10 6 10 8 carcinoma cells) were implanted into the left lobe of the liver. And then a comparative observation was performed in 3 groups included:1. the successful rate of implanted tumors; 2. the volume change and the growth rate of implanted tumors; 3. the biological features of implanted tumors in histopathology and electronic microscope photographs and DSA features of implanted tumors. Results The successful rates of transplanted tumors in the three groups were 7/20, 10/20 and 19/20 respectively. The successful rate of the 3rd group was the highest of the 3( P

Objective To investigate the related mechanism of ligamentum flavum (LF) hypertrophy in diabetic pa-tients with lumbar spinal canal stenosis ( LSCS ) .Methods Twenty-four diabetes mellitus patients [ DM (+) ] and twenty normoglycemic patients [ DM (-) ] with LSCS were enrolled in this study .Sorbitol in LF was analyzed using D-Sorbitol/Xylitol test kit .The thickness of LF was measured by CT .The structure of LF was observed after HE and Masson's trichrome staining .The cell cycle and proliferation of fibroblastic cell NIH 3T3 line cultured in high glucose were analyzed .Sorbitol of NIH3T3 was detected under different backgrounds in vitro, normal glucose , high glucose and high glucose burdened with aldose reductase inhibitor ( ARI) , Epalrestat .The expression of inflammatory factors was detected by qPCR and Western blot under above different backgrounds .Results LF of diabetic patients exhibi-ted significantly higher level of sorbitol and pro-inflammatory cytokines , TGF-βand of CD68-positive staining than that of the normoglycemic subjects ( P<0.01 ) .The diabetic LF was significantly thicker than that of the controls , and showed evidence of degeneration .The high glucose-cultured fibroblasts exhibited significantly higher levels of sorbitol , pro-inflammatory factors , and TGF-βcompared to the low glucose-cultured cells , and these levels were dose-dependently reduced by treatment with the aldose reductase inhibitor (P<0.05).Conclusions Sorbitol level of the LF is significantly increased in the DM patients with LSCS .Increased sorbitol recruites inflammatory factors and fibrogenic-related factor TGF-βin LF of DM patients with LSCS which may contributes to the LF hypertrophy .

Objective To investigate the value of multi-slice spiral CT image texture analysis in differentiating metastatic (MLN) from non-metastatic lymph nodes (NLN) in patients with rectal cancer.Methods Thirty five patiets with rectal cancer who were pathologically confirmed by total mesorectum excision were included retrospectively,with regional lymph nodes (short-axis diameter of larger than 3 mm)found in preoperative CT images.All the patients underwent preoperative abdominal and pelvic dynamic contrast-enhanced CT scan.Regional lymph nodes were identified according to pathological findings,and were divided into MLN and NLN groups.The short-axis diameter,short-to long-axis diameter ratio of lymph nodes were manually measured and calculated,and the texture features,including skewness,kurtosis,variance,entropy and inverse difference moment,were analyzed.The above parameters between MLN and NLN groups were compared using independent sample t test or Mann-Whitney U test.ROC curve analysis was performed regarding the statistically significant parameters and the areas under curve (AUC) were calculated.Multivariate Logistic regression analysis was accomplished to obtain the independent predictive factor of diagnosing regional lymph nodes.Results A total of 68 regional lymph nodes were obtained and consisted of 31 MLNs and 37 NLNs.The short-axis diameter,kurtosis,and entropy of the MLN group were significantly higher than those of the NLN group (all P＜0.05).Whereas,the short-to long-axis diameter ratio,skewness,variance,and inverse difference moment did not differ significantly between the two groups (all P＞0.05).The AUC for distinguishing MLN from NLN of the short-axis diameter,kurtosis and entropy were 0.79,0.67,and 0.85,respectively.Multivariate logistic regression analysis showed that only entropy (odds ratio=8.48,95％ confidence interval was 3.01 to 23.92,P＜0.01) was screened out as the independent variable,which suggested that the entropy was the unique predictor for characterizing regional lymph nodes of rectal cancer.Conclusion Multi-slice spiral CT images texture analysis can facilitate the accurate differentiation between MLN and NLN in patients with rectal cancer,and especially the entropy has the optimal reference significance.

Objective: To investigate the circadian ryhthm v ariation of 2-125I-iodomelatonin (125I-Mel) binding sites in the human peripheral leukocytes in patients with acute cerebral infarction. Methods: Melatonin binding sites in the human peripheral leukocytes were studied using 125　I-Mel as a radioligand (radioligand binding assays).A ll patients ［age: (70.18±11.70) years］ were diagnosed by CT according to the standard ［Chin J Nerv， 1996,29(6):379］.

There was no significant variation in the patient grou p (P>0.05). The specific binding in the peripheral leukocytes at midlight in the patients with acute cerebral infarction were lower than that of the control . Conclusion: The expression of Mel receptor decreases in the pa tients wit h acute cerebral infarction and the circadian ryhthm variation of 2-125I -Mel appears abnormal.

BACKGROUND: It is necessary to keep a good cervical curvature for improving nerve symptom in patients with cervical spondylotic myelopathy (CSM). It is verified that cervical anterior plate internal fixation implant is effective to restore the physiological curvature of cervical vertebra.OBJECTIVE: To assess the physiological lordosis of cervical vertebra in CSM patients after cervical anterior plate internal fixation implantation.DESIGN: Observational study.SETTING: First Affiliated Hospital of Nanchang University.PARTICIpANTS: Totally 72 CSM patients were enrolled at Department of Orthopaedics, First Affiliated Hospital,Nanchang University from February 2003 to January 2006, including 46 males and 26 females, aged 45-70 years,averagely 54 years, with the history of 2-6 years. Inclusive criteria included ①cervical spinal cord compression shown in MRI, and ②using autogenous iliac bone. The experiment was approved by Hospital Ethics Committee, and all patients signed the informed consent. Cervical anterior plate was Orion locking plate offered by Shufamo Company. There were single segmental discectomy group (n =32) and two-level segmental discectomy group (n =40) according to experimental requirement.METHODS: ①Anterior decompression plus autogenous iliac bone implant plus titanium plate internal fixation were utilized.The patients were in supine position; shoulder and back were blocked up; neck backward, and endotracheal tube was done under general anesthesia. Transverse or oblique incision was made at right anterior neck. Discectomy decompression was performed with Caspar vertebra ecarteur. Three-dimensional autogenous iliac bone was implanted in decompressed intervertebral space. Immediate stability was obtained after Orion locking titanium plate was fixed, with placement drainage, and then the incision was sutured. ②Postoperative daily activities were conducted with cervical gear, which was removed 8 weeks later. ③Lateral cervical vertebrae X-rays were taken before operation, immediately after operation, 6 and 12 months after operation. Lordosis of the fusion segment was measured with Cobb's angle, and lordosis of cervical vertebra was assessed with D value. These data were analysed by statistic software. ④Bone fusion of the patients was followed up for 12 months after operation. Vertebral fusion standards included no abnormity between two spinous processes of the fusion segment, no lucency between implant and vertebra, as well as bone trabecula across the interface between implant bone and vertebra. ⑤Biocompatibility between material and host was observed during follow-up.MAIN OUTCOME MEASURES: ①Changes of Cobb's angle and D value at different time points before and after operation,and ②Bone fusion and rejection were followed up.RESULTS: Totally 72 patients were involved in the result analysis. ①Cobb's angle was larger and D value was higher immediately after operation, 6 and 12 months after operation than those before operation in the single segmental discectomy group and the two-level segmental discectomy group (P＜0.05). ②Findings of 12-month follow-up showed that bone fusion appeared in all patients of the two groups. ③No significant rejection was found after titanium plate internal fixation implantation. It was found that material and host had a good biocompatibility.CONCLUSION: It is satisfactory to restore physiological lordosis of cervical spine by using cervical anterior plate internal fixation plus autogenous iliac bone for CSM.

To investigate the expression of the subunit p65 of NF-kappaB and inhibitor kappa B alpha (IkappaBalpha) in mouse uterus during peri-implantation, thereby investigating whether transient activation of nuclear factor-kappaB (NF-kappaB) takes place during embryo implantation in mice. Immunohistochemical technique was used to examine the expression and localization of p65 in endometrium or deciduas, and Western blot analysis was employed to detect the levels of IkappaBalpha protein in mouse endometrium or deciduas. P65 protein was detected in stromal cells, epithelial cells of endometrium as well as in myometrium. Staining was predominately seen in the cytoplasm of the cells. Staining intensity for p65 was stronger in the epithelial compartment than the stromal compartment and myometrium. Staining intensity increased slightly during pregnancy, and it reached a high level on pregnancy day 5 and day 8. In contrast to p65, the level of IkappaBalpha protein was lowest on pregnancy day 5 in all groups. Our results suggested that NF-kappaB may regulate embryo implantation by its transient activation in mice.
