Objective To investigate the role of local aldosterone system in oncofetal fibronectin ( oncofetal FN) mRNA expression and reactive oxygen species (ROS) production in human mesangial cells (HMCs) exposed to short-term intermittent high glucose and the effect of Fenofibrate.Methods The HMCs were divided into 8 groups:normal glucose(NG) ;osmotic fluctuation(OF) ;mean glucose load (MGL) ;stable high glucose (SHG),short-term intermittent high glucose (IHG) ; intermittent high glucose plus eplerenone (IHGE) ; intermittent high glucose plus fenofibrate(IHGF) ; and normal glucose plus fenofibrate (NGF) groups.The mRNA expression levels of Aldosterone synthase ( CYP11 B2 ),11 β-hydroxysteroid dehydrogenase type 2 ( 11βHSD2 ) and oncofetal FN were determined by RT-PCR.The expression of CYP11B2 protein was determined by western-blot.Aldosterone level in cell culture supernatant was detected by radioimmunoassay.The expression and translocation of mineralocorticoid receptor (MR)protein were assayed with confocal laser scanning microscopy. ROS levels were determined by Fluorescence microscopy and fluorescence microplate reader.Results ( 1 ) MGL,SHG,and IHG groups showed a 2.41,3.63,and 4.45 times increase in CYP11B2 mRNA expression,and a 1.83,2.15,and 2.78 times increase in CYP11B2 protein expression,respectively,compared with NG group (P ＜ 0.05 ).The aldosterone levels of HMCs culture supernatant in MGL,SHG,and IHG groups were also increased,being 1.49,2.04,and 2.54 times of that in NG group ( P＜0.05 ),and the degree of elevation in IHG group was more marked than that in SHG group( P＜0.05 ).MR was activated and translocated from cytosol to nucleus in MGL,SHG,and IHG groups.Quantitative analysis showed the ratioes of cytosol/nucleus fluorescence intensity in MGL,SHG,and IHG groups were 15％,38％,and 53％ decreased as compared with that in NG group,and the decrease was more marked in IHG group ( P＜0.05 ).(2) Oncofetal FN mRNA expression and ROS levels in MGL,SHG,and IHG groups were increased,being 1.54,2.31,3.65 and 1.26,1.91,2.48 times of those in NG group,respectively ( P＜0.05 ),and this increase was more marked in group IHG ( P＜O.05 ).Compared with IHG group,oncofetal FN mRNA expression and ROS levels in group IHGE were significantly decreased by 54％ and 53％,and in group IHGF by 45％ and 39％. ( 3 ) CYP11B2 mRNA,protein,and aldosterone levels in IHGF group were decreased by 74％,59％,and 50％,and the activation of MR in group IHGF was inhibited when the ratio of cytosol/nuclear fluorescence intensity was increased 1.88 fold as compared with that in group IHG ( P＜0.05 ).Conclusions Increased expressions of oncofetal FN and ROS by HMCs induced by short-term intermittent high glucose were nore marked than those induced by stable high glucose.The mechanism was associated with activation of local aldosterone system.Fenofibrate may inhibit the activation of local aldosterone system and alleviate the injury to HMCs induced by intermittent high glucose.

In view of the current situation of the teaching of diagnostics, this paper analyzes the ex-isting problems and deficiencies , and puts forward the teaching reform of the National Medical College Students' clinical skills competition. Through the construction of experimental teaching demonstration center of clinical skills, we set up theclinical skills associationamong the students, boldly try innovative training, strengthen humanistic education and take other measures to improve the quality of clinical practice teaching of diagnostics, so as to achieve the purpose of the competition focusing on promote teaching, learning and using by competition.

Objective To summarize the clinical experience in treatment of the Lisfranc joint injury with open reduction and internal fixation at early stage. Methods Twelve patients ( including ten males and two females at average age of 34 years) with early stage Lisfranc joint injury received open reduction and screw/wire fixation from 2005 to 2010. According to the Myerson classification, there were two patients with type A, eight with type B and two with type C. All the patients received open reduction and internal fixation with screw or Kirschner wire within 17 days after injury. The post-operative function was estimated by mid-foot scoring scale of AOFAS. X-ray and CT scan were used in radiography estimation. Results All the patients were followed up for average 33 months ( range, 6-60 months). The mean score of post-operative mid-foot scoring scale of AOFAS was 74.5 points ( range, 53-96 points), with excellent result in eight patients, good in two and fair in two. The anatomical reduction was observed in eight patients and all the patients obtained bony union according to the results of X-ray and CT scan.There was no any complication found.Conclusions Open reduction and internal fixation is a good choice for the treatment of Lisfranc joint injury at early stage. A preoperative comprehensive analysis combined with clinical X-ray and CT scan is necessary.

OBJECTIVETo study the active constituents from Alternanthera philoxeroides.

METHODThe constituents were isolated with silica gel and Toyopearl HW-40C gel column chromatography and purified by HPLC. Their structures were elucidated by spectroscopy.

RESULTNine compounds were isolated and identified as phaeophytin a (1), pheophytin a' (2), oleanoic acid (3), beta-sitosterol (4), 3beta-hydroxystigmast-5-en-7-one (5), alpha-spinasterol (6), 24-methylenecycloartanol (7), cycloeucalenol (8), phytol (9).

CONCLUSIONCompounds 1,2,5,7-9 were isolated from this plant for the first time.

Faciliysyion techniques were used to help improve the extremity motor functions of 43 elderly and 79 middle aged or youthful stroke patients. The Fugl-Meyer scale was employed for thc assessment of the functional status. The results showed that the motor function of upper extremty of thc elderly patients was not improved. but the motor function of lower extremity was improved significantly. The motor functions of upper and lower extremities were all improved significantly in the middle-aged or youthful patients. In early rehabilitation group the Increased motor function marks of the upper extremity of the elderly stroke patients were less than that of the middle-aged or youthful stroke patients. the increased motor function marks of the lower extremity of The elderly stroke patients were less significantly than that of the middle-aged or youthful stroke patients also. In late rehahilitation group the increased motor function marks of the lower extremity in elderly stroke patients were more than that in the middle-aged or youthful stroke patients.
