Objective To evaluate retrospectively the role of 18 F-fluorodeoxyglucose (FDG) PET/CT associated with MRI in the localization of epileptogenic foci. Methods Sixty-seven patients with medically resistant epilepsy were included from 2003 to 2008. All underwent 18F-FDG PET/CT and MRI for presurgical evaluation as well as post-surgical evaluation 12 to 65 months after operation. Based on postoperative seizure occurrence, patients were divided into two groups. One group was free of seizures ( Engel classification Ⅰ, Group 1) and the other was with postoperative seizure occurrence of any type ( Engel classification Ⅱ-Ⅳ, Group 2). X2-test or Fisher's exact test was used for the statistical analysis. Results About 71.6% (48/67) patients were defined as group 1, and 19 patients were group 2 ( 11 were Engel Ⅱ , 5 were Engel Ⅲ, and 3 were Engel Ⅳ ). In Group 1, no statistically significant difference was found between concordant (45/63) and discordant findings (3/4) with regard to 18F-FDG PET/CT and MRI images (Fisher's exact test, P ＞0.05). For 41 patients that showed focal abnormality both on MRI and 18F-FDG PET/CT, 80.5% (33/41) were found in group 1. For 20 patients that showed focal lesions on MRI while with multi-focal or generalized abnormal metabolism on 18F-FDG PET/CT, 11 (55.0%) were in group 1 and9 (45.0%) were group 2. There was no significant difference (33/41 vs 11/20, X2 =4.34, P ＜0.05 ). Conclusion 18F-FDG PET/CT associated with MRI may offer more helpful information for pre-surgical evaluation and prediction of prognosis of epileptic patients.

Three human leucine-rich repeats and immunoglobulin-like domains (LRIG) genes and proteins, named LRIG1-3, has been previously characterized and it was proposed that they may act as suppressors of tumor growth. The LRIG1 protein can inhibit the growth of tumors of glial cells and the down-regulation of the LRIG1 gene may be involved in the development and progression of the tumor. Real-time reverse transcription-polymerase chain reaction (RT-PCR) is a recently developed technique for quantitative assessment of specific RNA levels. In the current study, it was demonstrated that LRIG1-3 and EGFR mRNA was detected in human pituitary adenoma cell lines and a normal pituitary sample, with differences in the expression levels. Compared to the normal pituitary samples, the expression of LRIG1-3 in HP75 cell line was lower, but the expression of EGFR in HP75 cell line was higher. The results are consistent with LRIG1-3 being tumour suppressor genes, and LRIG genes decreasing the expression of EGFR. The ratio of EGFR/LRIG1 was increased at least 13-fold in HP75 cells compared with the normal pituitary cells, which was also the case for the ratio of EGFR/LRIG2 (14-fold increase in HP75) and EGFR/LRIG3 (11-fold increase in HP75). Further studies were needed to elucidate the explicit role of LRIG genes as negative regulators of oncogenesis in human pituitary adenoma.

The expression and possible role of integrin-focal adhesion kinase signal pathway in invasive pituitary adenomas were explored. Forty-nine human pituitary adenomas were detected for the expression of integrinbeta1 (INTbeta1) and focal adhesion kinase (FAK) by immunohistochemistry, and their correlation with the invasiveness of pituitary adenomas as well as between themselves was analyzed. The results showed that INTbeta1 was expressed in 46 cases (93.9%) and FAK in 36 cases (73.5%), respectively, and their expression levels were highly correlated with tumor invasiveness, but not with the tumor types. It was suggested that the integrin-focal adhesion kinase signal pathway plays a role in the invasiveness of pituitary adenomas.

Objective To investigate the effect of high iodine traditional Chinese medicine in the treatment of subclinical hypothyroidism in serum VB12,Hcy and thyroid function.Methods 84 patients of subclinical hypothyroidism from August 2014 to May 2016 in our hospital randomly divided into two groups,the control group of 42 cases were treated with levothyroxine sodium tablets treatment,42 cases in the experimental group received more with high iodine traditional Chinese medicine.The changes of serum VB12,Hcy and thyroid function were observed before and after treatment in two groups. Results Compared with before treatment, levels of blood lipid,Hcy and TSH in two groups significantly decreased,levels of VB12 increased(P<0.05);compared with the control group after treatment,levels of blood lipid,Hcy and TSH in experimental group were significantly lower than the control group, the level of VB12 was higher than the control group,the differences were statistically significant (P <0.05).Conclusion High iodine can effectively reduce blood lipids in patients with subclinical hypothyroidism,levels of Hcy and TSH in pregnancy,increased the levels of VB12,which has good clinical curative effect.

BACKGROUND:The bony crista has been found in the distal humeral medullary cavity,but its specific morphological characteristics and clinical significance are not clear.OBJECTIVE:To study the morphology of bony crista inside the distal intramedullary of the human humerus and its potential clinical relevance.DESIGN,TIME AND SETTING:CT scanning and measurement as well as visualized observation to the specimen for the dry adult humeri was performed at CT Room and Department of Orthopaedics,First Affiliated Hospital,Nanchang University from June to December 2007.MATERIALS:A total of 80 dry adult humeri (left:49;right:31) were purchased from the Department of Anatomy,Medical College of Nanchang University,excluding the fractured and lesion humerus.METHODS:The low 1/3 of eighty human humeri were scanned by 16 layer spiral CT.The morphological features of the intramedullary bony prominence above the olecranon fossa was described in terms of coronal plane,sagittal plane and transverse section after three-dimensional reconstruction.The low 1/3 of twenty humeri were then split vertically in the middle line in coronal plane,to view the intramedullary bony crista directly.MAIN OUTCOME MEASURES:The bony crista mainly located on the medial or lateral side,the range of the bas'dar part of the bony crista,alinement characteristic of the bony crista.RESULTS:The extent of intramedullary bony crista ranged from 1.9 to 3.2 cm (mean 2.6 cm) above the olecranon fossa,the density similar to cortical bone,with an basement posterior,and medial part and lateral side intero-inferiody incline.59 out of the 80 humeri,medial side dorminated;on the rest humeri the lateral side dorminated.2 or 3 parallel lines on the dorminate side,irregular alignment on the other side.CONCLUSION:The study described the morphology of the distal intramedullary bony crista of the humerus,which has never been reported so far.In addition,its clinical relevance in terms of the internal fixation of fracture on the distal humerus and elbow arthroplasty was also demonstrated.

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.

Objective To investigate the clinical value of combined detection of the serum levels of CA125,CA72-4 and tumor specific growth factor(TSGF)in the diagnosis of ovary cancer and the curative effect.Methods Serum levels of CA125,CA72-4 and TSGF in 68 patients with ovary cancer,53 patients with benign ovary rumor and 50 normal controls were measured by chemiluminescent immunoassay(CLIA)and chemical colorimetry.Results and clinical data were statisticaly analyzed.Results The levels of CA125,CA72-4 and TSGF in ovary cancer group were higher than that in the benign ovarian tumor group and healthy controls(all P ＜0.01).When use three tumor markers united detection,sensitivity,specificity and accuracy were 91.2％,83.0％ and 87.4％ respectively.The sensitivity and accuracy was higher than any single detection.The specificity with single CA125 testing was consistently.The levels of CA125,CA72-4 and TSGF in patients with ovary cancer were significantly different after surgical treatment for five days(all P ＜0.05).Conclusion The combined detection of the three markers may increase the positive rate in the early diagnosis of ovarian cancer,and help to differentiate the benign and malignant ovarian tumor,but also is valuable to observe the curative rate and postoperative monitor of the ovary cancer.
