BACKGROUND:Donkey-hide glue reinforcing bone oral solution (DGRBOS) is effective on preventing and treating fracture, but the mechanism of harmacology is still not clear. Vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF-2) are important cytokines, which can promote blood vessel growth and osseous anabolism during fracture healing.OBJECTIVE: To investigate the effects of DGRBOS on expression of VEGF and FGF-2 in the process of fracture healing of SD rats' fracture of tibia in bony callus, and explore the mechanism of DGRBOS in the treatment of fracture.DESIGN: A completely randomized controlled study.SETTING: Department of Traumatic Orthopedics, Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology.MATERIALS: Ninety female Sprague-Dawley (SD) rats, with a mean weight of (368±40) g, aged about 3 months, wereprovided by Center of Animal Experiment, Tongji Medical College, Huazhong University of Science and Technology.Experimental drug: DGRBOS was donated by Xinjiang Huashidan Pharmaceutical Co., Ltd. The qili linking bone pill,positive control drug, was purchased from Hunan Pharmaceutical Co., Ltd.METHODS: This experiment was carried out in the Laboratory for Bone Metabolism of Integration of Chinese and Western Medicine (Laboratory of Provincial Level), Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from June to November 2005. Transverse midshaft fractures were produced on the right tibia in these rats using three-point bending technique, and 90 rats were randomly divided into three experimental groups:the DGRBOS group (n =30): according to medicine conversional method between human being and animal, 2 mL DGRBOS was fed to every mouse by intragastric administration at 2 vices/day; the qili linking bone pill group (positive control group, n =30): the pills dissolved in distilled water at 225 g/L, and consequently were administered intragastrically into mice at 2 mL/vice and 2 vices/day; normal saline group (negative control group, n =30): normal saline was administered intragastrically into mice at the coordinative capacity and same frequences. Selecting 4, 7, 14,21 and 28 days during the experiment, the immunohistochemistry method was adopted to detect the change of expression of VEGF and FGF-2 through computing value of mean optical degree (MOD) and number of the positive cells.

BACKGROUNDThe prognosis of unresectable large hepatocellular carcinomas is poor. This study evaluated the efficacy and safety of sorafenib combined with transcatheter arterial chemoembolization and radiofrequency ablation in the treatment of hepatocellular carcinomas larger than 5 cm.

METHODSThe treatment of 22 patients with large, unresectable hepatocellular carcinomas (5.0-16.5 cm) treated with sorafenib after transcatheter arterial chemoembolization combined with radiofrequency ablation between 2007 and 2011 was reviewed. The local effects, survival rates, toxicity, and prognostic factors were analyzed.

RESULTSDuring a follow-up of 9-49 months, 19 patients died and three survived. The median overall survival was 32 months. The overall cumulative 12, 24, and 36-month survival rates were 85.9%, 66.8%, and 23.5% respectively. Technical effectiveness was achieved in 12 out of 28 lesions (42.85%) at the first CT check. The median time to tumor progression was 21 months. The progression-free survival rates at 6, 12, and 24 months were 90.9%, 72.0%, and 38.4%, respectively. Combined therapy was generally well tolerated. There was only one major procedure-related complication, biloma (4.5%). Sorafenib-related adverse events exceeding grade 3 were hand-foot skin reaction (2/22, 9.1%), gastrointestinal hemorrhage (1/22, 4.5%), and diarrhea (2/22, 9.1%). The absence of vascular invasion before treatment was found to be the best prognostic factor in the univariate analysis.

CONCLUSIONSSorafenib combined with transcatheter arterial chemoembolization and radiofrequency ablation is a promising approach to the treatment of large, unresectable hepatocellular carcinomas. However, large-scale randomized clinical trials are needed to determine the future role of this treatment.

In this study, the inhibitory effect of jujuboside A (JuA) on a penicillin sodium (Na-PCN) induced hyperactivity model was investigated. Cortical EEG (electroencephalogram) and the concentration of hippocampal Glutamate (Glu) were monitored simultaneously in vivo as indicators of rat's excitatory state. Power spectral density (PSD) and gravity frequency of PSD were calculated. JuA (0.05 g/L and 0.1 g/L) inhibited the EEG excitation effect caused by Na-PCN by increasing the power of delta1 and delta2 bands (P<0.01 vs model) and lowering the gravity frequency of PSD (P<0.01 vs model). JuA also remarkably reduced the Glu elevation induced by Na-PCN (P<0.05 vs model). Diazepam also depressed Glu concentration and lowered the gravity frequency, but it showed a different EEG pattern in increased beta2-activity (P<0.01 vs model). EEG excitation caused by Na-PCN correlated with Glu elevation during the first hour. Neurophysiological inhibitory effects of JuA and diazepam were more persistent than their Glu inhibitory effects.

OBJECTIVETo propose a method for predicting the postoperative anterior chamber depth value (ACD) based on the evaluation standard of contrast sensitivity function (CSF).

METHODSIn a personalized eye model, the natural lens was replaced with an artificial lens, and the tracing method based on ZEMAX software was utilized to simulate the pseudophakic optical system. The best MTF curve was obtained through optical optimization to calculate the CSF and determine the best contrast sensitivity (CS) curve. The best ACD value was acquired according to the CSF curve. The data form 10 cataract cases without retinal diseases were obtained and the postoperative ACD value was predicted using Holladay, Hoffer Q, SRK/T and the proposed method.

RESULTSConsistency analysis of the results showed that all the ACD values predicated by the 4 methods fell in 95% consistency within the boundaries, and the differences in the largest absolute value between the 3 methods (Holladay, Hoffer Q, and SRK/T) and the proposed method were 0.73 mm, 0.65 mm, and 0.68 mm, and the calculation results of the mean value were 5.846 mm, 5.804 mm, and 5.825 mm. Clinically, the two methods were deemed to have good consistency.

CONCLUSIONThe proposed method establishes a connection between the contrast sensitivity curve and ACD to allow better refraction adjustment for the patients.

OBJECTIVE: To explore the safety and efficacy of "chimney graft" technique during thoracic endovascular aneurysm repair (TEVAR) in aortic arch lesions. METHODS: Th e methods, results and the incidence of complications in 25 patients, who received "chimney stent" therapy for aortic arch disease, were reviewed and analyzed. RESULTS: From August, 2010 to August, 2014, 25 aortic arch lesions were treated by TEVAR with "chimney stent", 18 patients were male and 7 were female. The average age was 38-78(65±5.8) years old. Five patients received "chimney stents" for left common carotid artery, while 20 patients received "chimney stent" for left subclavian artery. Three cases showed small amount of Type I leak under immediate postoperative angiography without treatment. The leak was disappeared 1month later. Two patients appeared left upper limb weakness and one of them showed dizzinesss simultaneously. Both of them recovered gradually in follow-up process. Th ere was no limb ischemia or necrosis. Th e locations of aortic and "chimney stent" were stable without any migration and leak complications. CONCLUSION "Chimney graft" technique is a safe and effective treatment for aortic arch lesions due to lack of proximal anchoring zone. The follow up results in a short-term is satisfied.

OBJECTIVETo identify the mutation of low density lipoprotein receptor(LDLR) gene in a large Chinese family with familial hypercholesterolemia(F H) and make a discussion on the pathogenesis of FH at the molecular level.

METHODSInvestigations were made on a patient with the clinical phenotype of homozygous FH and his parents for mutations of promoter and all 18 exons of LDLR gene. Screening was carried out using Touch down PCR and a g arose gel electrophoresis, combined with DNA sequence analysis. The results were compared with the normal sequences in GenBank and FH database (www.ucl.uk/fh) t o find the mutation. Then the mutation was identified in other members of the family. In addition, the authors screened the apolipoprotein B(100) (apoB(100)) gene f or known mutations (R3500Q) that cause familial defective apoB(100) (FDB) by PCR-RFLP.

RESULTSA novel homozygous IN III 5' GT --> AT mutation in the splice donor of LDLR intron 3 was detected in the homozygote propositus with FH. The mutation was also identified in four heterozygous carriers in his family. No mutations R3500Q of apoB(100)were observed.

CONCLUSIONA homozygous G --> A splice mutation in LDLR gene was first reported. The change of the splice donor in LDLR intron 3 may cause skipping of exon 3, which is responsible for FH. Perhaps it is a particular pathogenesis for Chinese people.
