OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.

METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.

RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).

CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

Objective To study the influence of low-iodine diet on the expression of homeobox gene nkx2.1 in rat cerebral tissue. Methods Forty female Wistar rats were randomly divided into two groups according to body. quality: low-iodine group and control group,both fed with low-iodine feed at an iodine content of 13.66 μg/kg,respectively given the deionized water and 200 μg/L KIO3 solution. The hormone levels of two group rats were determined with chemiluminescence immunoassay after three months, and then mated with healthy male rats. Cerebral tissues were taken from the fetus of 16-day pregnancy,newborn and 20 days old offspring in low-iodine and control group to detect the content of nkx2.1 mRNA using real-time fluorescence quantitative PCR (FQ-PCR) techniques. Results Serum TT3, TT4, FT3, FT4 level of rats in low-iodine group(0.89±0.20, 0.32±0.16, 3.33± 0.61, 3.28±0.80) was respectively lower than that in the control group(1.04±0.06, 39.42±14.68,4.83±0.33, 26.99±4.48;t = 2.71,6.52,5.70, 12.89, P < 0.05 or < 0.01). The relative nkx2.1 mRNA expression was(5.60± 0.30)×10-3, (1.20 ± 0.29)×10-3, (0.18± 0.06)×10-3 respectively in the fetus of 16-day pregnancy, newborn and 20 days old offspring of control group, while it was (3.00 ± 0.55)×10-3, (1.90 ± 0.21)×10-3,(0.69 ± 0.15)×10-3 in the low-iodine group. The difference of nkx2.1 mRNA expression was significant among fetal and neonatal rats in the control group and low-iodine group(F = 210.07,162.40, both P < 0.01). The nkx2.1 mRNA expression of newborn rats was lower than that of 16-day pregnancy in both groups(P < 0.01), and that of 20 days old rats was lower than that of 16-day pregnant and neonatal rats(P < 0.01). The 16-day pregnant rats of control group had obviously higher level of nkx2.1 expression than those in the low-iodine group(t = 16.073, P< 0.01), while the nkx2.1 of newborn and 20 days old low-iodine rats expressed much higher than healthy rats(t = 7.573,12.221, P < 0.01). Conclusions Brain development retardation caused by low-iodine is closely related to nkx2.1 differential expression in the brain tissue.

Objective To investigate the clinical significance of generalized epilepsy with febrile seizures plus(GEFS+ ). Methods The data of one family with GEFS+ were retrospectively analyzed by studying clinical manifestations, physical examinations, electroencephalogram(EEG), 24 hours dynamic EEG monitoring, et al. Some of the patients were examined by CT. Results Ⅳ 12, her chief complaints when admitted to hospital were frequent spasm for 3 days. She began to appear febrile seizures (FS) from 8 months after birth, and frequent generalized tonic - clonic FS appeared during that time. There were 36 people in 5 generations of the family including 14 patients (8 males and 6 females) ,aged from 4 years and 5 months to 82 years. FS presented in 8 cases (Ⅱ 2, Ⅲ1, Ⅲ4, Ⅲ6, Ⅳ1, Ⅳ11, Ⅳ17, Ⅴ2),febrile seizures plus(FS +) in 4 cases ( Ⅳ2, Ⅳ12, Ⅳ13, Ⅳ14), ES + and absence seizures in 1 case ( Ⅴ1 ), uncertain type in 1 case (Ⅰ2). The results of EEG indicated that 12 cases were normal and 4 cases with FS+ and 1 case with absence seizures had epileptic discharges. Apart form Ⅳ13, Ⅳ14 who were treated with magnesium valproate, the dosage for the other patients decreased, or medicine terminated or without medicine, and all the patients had no recurrence of seizures. The intelligence, movement development and neurological examinations of the family were all normal. Head CT scan of 3 cases were normal. Conclusions GEFS+ is autosomal dominant inheritance disease with conspicuous genetic heterogeneity and phenotypic heterogeneity. The apprehension of GEFS+ plays an important role in diagnosis and differential diagnosis of epilepsy in childhood.

Objective The frequency and the anatomic distribution of involved regional nodes in recurrent and locally advanced breast cancer were analyzed, in order to evaluate the rational of conventional regional node radiation technique and provide evidence for target definition of breast cancer . Methods Patients with recurrent or locally advanced breast cancer who were treated in our hospital from August 2003 to December 2009 were included in this study. 111 patients had contrast enhanced chest CT images of the whole regional nodes before treatment. The regional nodes were categorized into 8 anatomical substructures including medial and lateral supraclavicular nodes ( SC-M, SC-L), axilla nodes ( ALN )- Ⅰ , Ⅱ , Ⅲ,infraclavicular nodes (IFN), Rotter's nodes (RN) and internal mammary nodes (IMN). The frequency of involvement and anatomical distribution of the involved nodes on CT images were analyzed. Results A total of 111 patients were enrolled this study and 199 anatomical substructures with involved nodes were identified. The frequency of involvement were :SC-M 33, SC-L 21, ALN- Ⅰ 30, ALN-Ⅱ 25, ALN-Ⅲ + IFN 35, RN 27, IMN 28. Supraclavicular region and axilla were the most frequently involved area (72. 3% ).The average depth of the SC-M and SC-L nodes was 33.48 mm ± 10. 57 mm and 45.62 mm ±20. 45 mm,and 51.5% and 71.4% of the SC-M and SC-L nodes were located more than 3 cm deep from the skin. The axilla nodes were located cranial and caudal to the axillary vein in 5 and 20 locally advanced breast cancer patients and in 64 and 28 patients who received prior axillary dissection. The majority of involved IMN was located within the first 3 intercostal spaces (26/28). The average distance between the center of involved IMN and chest skin was 24. 23 mm ± 10. 28 mm. The average distance between the center of involved IMN and midline of the body was 29. 38 mm ±6. 7 mm. The center of involved IMN was 6.19 mm ±5.73 mm lateral and 5.73 mm ± 4. 56 mm posterior to the internal mammary vessels. Conclusions Conventional field design is unlikely to provide sufficient dose to the entire risk region because of individual differences.Individualized treatment planning based on CT would become feasible with increasing knowledge of natural risk of nodal involvement.

Objective To evaluate the association between 8 single nucleotide polymorphisms (SNPs)of vascular endothelial growth factor (VEGF ) gene and the risk of Alzheimer’s disease (AD ) in Shaanxi Han population.Methods We examined the potential association between AD and 8 SNPs of VEGF gene using the MassARRAY system.The participants enrolled in this study included 214 patients with AD and 249 healthy controls from Shaanxi Han population.SPSS16.0 and Haploview 4.2 were employed to analyze differences in genotypes, alleles and haplotypes between the two groups.Results The results showed that rs3025039 (3’UTR)were significantly associated with AD (P<0.05).Greater frequency of rs3025039 T allele (P=0.008,OR=1.527,95%CI=1.116-2.088)was found in AD subjects.Furthermore,strong linkage disequilibrium (LD)was observed in 2 locks (block1:rs699947-rs1570360-rs2010963;block 2:rs3024997-rs3024998-rs3025006)(D’>0.9).There were no significant haplotypes in block 1 and block 2 (P=0.034)found between the patients and controls.Conclusion These findings point to the role for VEGF gene polymorphisms (rs3025039)in AD of a Shaanxi Han population. Individuals with T allele of rs3025039 may be at a higher risk for AD.

ABSTRACT:Objective To study the effect of curcumin on the learning and memory ability in a rat model of Alzheimer’s disease (AD).Methods AD rat model was prepared using intraventricular injection of Aβ1-42. Curcumin was acutely (single injection before the behavioral tests)or chronically (injected for 6 consecutive days) injected intraperitoneally at doses of 50,100 or 300 mg/kg.Brain-derived neurotrophic factor (BDNF)protein (1 μg/side)or BDNF shRNA (2×10 5 units/side)was infused into the hippocampus.The behavioral changes in Y-maze,open field test and Morris water maze and the expression of BDNF in the hippocampus were analyzed. Results Acute treatment with curcumin had no significant effects on the spontaneous alteration,locomotor activity or water maze latency of AD rats.AD rats treated chronically with curcumin (300 mg/kg ) showed significant elevation in the spontaneous alternation (P <0.000 1)in Y-maze and memory ability in the water maze test (P <0.05 )compared with those in the saline group.Chronic treatment with 100 and 300 mg/kg of curcumin induced an increased level of BDNF in the hippocampus as compared with the saline controls (P <0.05 and <0.000 1). Intrahippocampal injection of BDNF significantly decreased the escape latency of AD rats in the water maze (F 4,2 9 5=5.813,P <0.01 ).Rats chronically injected with curcumin combined with shBDNF showed no difference in the swimming time in Ⅱ quadrant as compared with saline controls (P =0.657).However,rats in 100 mg/kg curcumin group,BDNF group and sham group had significantly increased swimming time than the saline controls (P <0.05, P <0.05 and P <0.000 1,respectively).Conclusion Curcumin may activate the downstream signaling pathways by upregulating the expression of BDNF and ultimately contribute to the improvement of learning and memory in AD rats.
