Objective To evaluate the MR findings of normal and abnormal collateral ligament. Methods The MR findings of 56 normal and 36 surgically confirmed injured collateral ligaments were retrospectively reviewed and compared. Results The normal tibial and fibular collateral ligaments were hypointense string on both T 1 and T 2 coronal MR images, with an average length of 6.8 cm for tibial collateral ligament and 5.7 cm for fibular collateral ligament. 36 collateral ligaments were injured, including 18 tibial and 12 fibular collateral ligaments. Three cases (6 ligaments) had both tibial and fibularcollateral ligaments injuries. The injury of collateral ligament was classified as: Grade I (18 ligaments), Grade Ⅱ (11 ligaments), and Grade Ⅲ (7 ligaments). The complications of anterior cruciate ligament sprains (13 cases), posterior cruciate ligament sprains (9 cases), meniscal tears (12 cases), bony contusion and fracture (7 cases), and joint effusion (20 cases) were found in 25 patients(78%). Conclusion Coronal MR imaging can clearly demonstrate the structure of the knee collateral ligaments, accurately diagnose and classify the ligament injury, and correctly detect the complications. MRI should be used as a routine examining method for knee trauma.

Methods Furannoligularenone was added to the medium of the suspension cells of N. tabacum after precultured for 10 d, then they were co-cultured for another 4 d. The biotransformed products were detected with HPLC and isolated by various chromatographic methods. The chemical structures of biotransformed products were elucidated on the basis of their physicochemical pro-perties and spectroscopic data. Otherwise, the influence of co-cultured time on conversion ratio was investigated either. Results The substrate, furannoligularenone (Ⅰ), was successfully biotransformed by N. tabacum cultured cells. Two products, 3-oxo-eremophila-1, 7(11)-dien-12, 8-olide (Ⅱ) and 3-oxo-8-hydroxyeremophila-1, 7(11)-dien-12, 8-olide (Ⅲ) were obtained. After co-cultured for 5 d, the mole conversion ratio of the substrate reached the highest (53.1%). Conclusion It's the first report on biotransformation of furannoligularenone by N. tabacum cultured cells.

Abstract: Objective To explore the effects of continuous light and benzene exposure on peripheral blood erythrocyte - Methods parameters and expression of miR 144/451 in the bone marrow of mice. This was a 2×2 factorial design. Photoperiod ， ， factor was set as normal and continuous light levels and mice were treated for 12 hours/12 hours light/dark or 24 hours light - respectively. The benzene exposure factor was set as non exposure and exposure levels. Mice were exposed to benzene by static 3 ， inhalation with a mass concentration of 0.0 and 32.5 mg/m for three hours per day five days per week for a total of four weeks. ， ， Specific pathogen free male C57BL/6 J mice were randomly divided into negative control group simple continuous light group - - ， ， simple benzene exposure group and combined exposure group with 12 mice per group. After benzene exposure peripheral ， blood was collected for the detection of erythrocyte parameters in four periods. After the mice were sacrificed the expression of - - - - miR 451a and miR 144 5p was detected by real time fluorescence quantitative polymerase chain reaction in bone marrow Results （ ）， ， tissues.

INTRODUCTIONErythroderma is a generalised inflammatory reaction of the skin secondary to a variety of causes. This retrospective study aims to characterise the features of erythroderma and identify the associated causes of this condition in our population.

MATERIALS AND METHODSWe reviewed the clinical, laboratory, histological and other disease-specific investigations of 225 inpatients and outpatients with erythroderma over a 7.5-year period between January 2005 and June 2012.

RESULTSThe most common causative factors were underlying dermatoses (68.9%), idiopathic causes (14.2%), drug reactions (10.7%), and malignancies (4.0%). When drugs and underlying dermatoses were excluded, malignancy-associated cases constituted 19.6% of the cases. Fifty-five percent of malignancies were solid-organ malignancies, which is much higher than those previously reported (0.0% to 25%). Endogenous eczema was the most common dermatoses (69.0%), while traditional medications (20.8%) and anti-tuberculous medications (16.7%) were commonly implicated drugs. In patients with cutaneous T-cell lymphoma (CTCL), skin biopsy was suggestive or diagnostic in all cases. A total of 52.4% of patients with drug-related erythroderma had eosinophilia on skin biopsy. Electrolyte abnormalities and renal impairment were seen in 26.2% and 16.9% of patients respectively. Relapse rate at 1-year was 17.8%, with no associated mortality.

CONCLUSIONOur study highlights the significant proportion of malignancy-related erythroderma in those whom common underlying causes such as dermatoses and drugs have been excluded. In cases of drug-related erythroderma, traditional medications and antituberculous medications are common causes in our population. Renal impairment and electrolyte abnormalities are commonly seen and should be monitored in patients with erythroderma.

AIM: To investigate whether cirrhosis affects the expression of hepatic glucuronosyltransferase (UGT) isoforms and its clinical significance. METHODS: Reverse transcription and polymerase chain reaction (RT-PCR) and Southern hybridization were used to determine the mRNA levels of five UGT isoforms in hepatic tissues. RESULTS: Compared to control group, UGT2B15 and UGT1A6 mRNA level in cirrhosis group increased by 227% and 166%, respectively. Compared to 0 fibrotic grade group, UGT2B15 mRNA levels of 1, 2, 4 fibrotic grade patients were 172%, 208% and 243%, respectively. UGT2B7 mRNA levels of 1, 2, 3 fibrotic grade patients were 156%, 208% and 192%, respectively. Inflammation grade showed no obvious effect on mRNA expression of most UGT isoforms. CONCLUSION: Cirrhosis affectes individual UGT isoform mRNA level. Degree of fibrosis has a significant effect on UGT mRNA expression.
