Objective To investigate the association between brain structure abnormalities and neuropsychology impairment in CAD patients.Methods Nineteen patients with CAD and 1 7 healthy adults were examed with MRI,and T1 WI,T2 WI,FLAIR,DWI and DKI image were performed,and then comparing the acquired MRI findings between two groups.Results Significant differences were observed for MK values in splenium and body of the corpus callosum,left cerebellar hemisphere and amygdala cerebelli.MK values of CAD group were lower than those of healthy group in these regions,and differences were statistically significant(P <0.05). There were significant correlation between MK values of the left amygdala cerebelli and MoCA scores in CAD group.Conclusion DKI could detect the changes of brain tissue microstructure in CAD patients early.The correlation between MK and neuropsychologi-cal function provides an important basis for early diagnosis and treatment.

Objective To study the changes of the urinary ?-1 microglobulin and urinary immunoglobulin G(IgG) and to investigate the relationship between these two proteins and the allograft function after renal transplantation.Methods Twenty-nine renal transplant recipients were included in the study.Urinary ?-1 microglobulin and urinary IgG were analyzed at d 1,7,14,21,28 after renal transplantation.The allograft function was evaluated based on the clinical manifestations,laboratory and imaging examinations,and the relationship between urinary ?-1 microglobulin,IgG and serum cretinine(SCr) were analysed. Results Urinary ?-1 microglobulin and urinary IgG correlated with SCr after renal transplantation in one month.Of all the 29 cases,14 experienced allograft function recovery(group A),and 15 failed(group B).Urinary ?-1 microglobulin decreased significantly in group A(P

Objective To explore the relationship between quality of life and sub-health state of Guangdong urban dwellers.Methods A total of 2 200 urban dwellers were investigated using SF-36 and Sub-Heahh Measurement Scale Version 1.0(SHMS V1.0).Results As for the scores in PCS,MCS,psychosocial symptom,cognitive function,social adaptability,those of man urban dwellers (respectively (78.89± 15.25),(73.15 ± 15.26),(63.73± 18.82),(62.13± 19.34),(68.04± 17.90)) were higher than those of woman dwellers (respectively(76.98± 14.20),(71.76± 14.72),(60.53± 18.28),(57.00± 17.89),(65.73± 17.07)).The difference was statistically significant (P<0.05).Bivariate correlation analysis showed that the PCS and MCS of quality of life were positively related with all dimensions of sub-health (P<0.001).Canonical correlation analysis indicated that vitality,social adaptability,psychosocial symptom and positive emotion were the main factors of sub-health status,and MCS was of quality of life.Conclusion Sub-health state of Guangdong urban dwellers is positively related with quality of life,and the more serious sub-health state is,the worse quality of life is.Therefore,intervention of subhealth and quality of life should be targeted to be strengthened according to the investigation.

Objective To investigate the effects of 5-azacytidine and estradiol on the methylation of CpG motifs and expression of DNA methyltransferasel (DNMT1) mRNA in patients with systemic lupus erythematosus (SLE) and normal controls.Methods Peripheral blood lymphocytes isolated from 12 patients with SLE and 11 normal human controls were stimulated with phytohaemagglutinin for one day followed by additional 3-day culture with or without the presence of 5-azacytidine of 1 μmol/L or estradiol of 30μg/L respectively.Then.the methylation of CpG motifs was detected by flow cytometry using anti-5-methylcytosine antibody,and DNMT1 mRNA expression by real time reverse transcription-PCR Results After treatment with 5-azacytidine,a decrease wag observed in the methylation of CpG motifs, but not in the expression of DNMT1 mRNA in peripheral lymphocytes from patients with SLE (1=18.60,P<0.01;t=1.56.P>0.05) and in those from the normal controls (t=5.63,P<0.01;t=2.17,P>0.05) compared with untreated lymphocytes.Nevertheless,there were no significant changes in the methylation of CpG motifs or expression of DNMT1 mRNA in lymphocytes from patients with SLE (t=1.53,0.93,respectively,both P>0.05) and normal controls (t=1.93,0.11,respectively,both P>0.05) after the treatment with estradiol.Conclusions The methylation of CpG motifs is suppressed efficiently by 5-azacytidine,and the suppression is unlikely to be associated with the decrease of DNMT1 mRNA.Estradiol has no significant impact on the methylation of CpG motifs and expression of DNMT1 mRNA in lymphocytes.

Objective To evaluate the clinical effects of partial fascicle from the ulnar nerve to biceps branch of musculocutaneous nerve to treat brachial plexus injury. Methods Six cases of brachial plexus injury were involved in this group.3 cases were upper trunk injury and 3 cases were accompanied partial lower trunk injury.A partial fascicle of ulnar nerve transfered to repair biceps branch underwent in all cases,phrenic nerve or accessory nerve were transfered to repair suprascapular nerve.The mean time from injury to surgery was 2.8 months.Patients were evaluated with regard to elbow flexion and should abduction ansle,grip strengthen,morbidity of ulnar nerve function lose. Results Five cases out of six got follow up.The mean period of follow-up was 18 months(range from 9-30 months).The average reinnervation time for the biceps muscle was 3.3 months. All the patients' recovery of elbow flexion Was M_3~+-M_5; and the shoulder adduction was 90°-180°;the grip strength was not downgraded. No notable impairment of the donor site nerve function was observed in 4 cases,just 1 case with a little more fascicle been harvested had partial ulnar nerve impairments. Conclusion The use of ulnar nerve partial fascicle to biceps branch combined with phrenic nerve or accessory nerve to suprascapular nerve to reconstruct upper roots avulsion of the brachial plexus is a valid and convenient procedure.It can obtain good functional restoration in elbow flexion and shoulder adduction in a resonable time.The cases with partial lower trunk injury of brachial plexus,the partial fascicle of ulnar nerve can still be used for repair the musculocutaneous nerve.

ObjectiveTo assess the values of 320-detector row dynamic volume CT angiography (CTA) and transthoracic echocardiography (TTE) in follow up of coronary artery aneurysm (CAA) caused by Kawasaki disease (KD).Methods320-de-tector row CTA and TTE were applied in long-term follow-up of 8 patients with CAA caused by KD.ResultsIn 8 patients, the mean age at onset was 41.63±22.70 months and the mean follow up time was 43.50±10.99 months. In acute phase, 3 cases of giant coronary artery aneurysms (GCAA) and 5 cases of mid-small CAA were diagnosed by TTE. A total of 16/32 arteries (50%) were involved. At the end of follow-up, 3 cases of GCAA and 2 cases of mid-small CAA were still diagnosed by TTE, and small CAAs were regressed in another 3 cases. A total of 6/32 arteries (18.75%) were involved. Simultaneously at the end of follow-up, a total of 7/32 arteries (21.9%) were involved by 320-detector row CTA. The distribution was consistent with that of TTE. Mean-while, there were one case of left circumlfex artery, one case of GCAA at distal of the right coronary artery, 2 cases of thrombus, 1 case of coronary stenosis and 2 cases of calciifcation.ConclusionsCAA caused by KD may be persistent for a long time. The thrombus, stenosis, and calciifcation of coronary can occurr at late phase in GCAA. TTE is sensitive and reliable to detect proxi-mal and middle segment of coronary lesions, but has limitations in detection of distal segment of coronary arteries. 320-detector row CTA has more comprehensively view of each coronary artery lesions and is especially sensitive and reliable to detect coro-nary thrombosis, calciifcation and narrowing in proximal and distal coronary arteries after acute phase.

A HPLC-QTOF MS method was established for analysis of components in Ophiocordyceps sinensis . The HPLC analysis was performed on an Agilent Zorbax SB Aq (150 mmí4.6 mm, 5 μm) with gr adient elution (5 mmol·L-1 ammonium acetate aqueous solution-acetonitrile), flow rate was 0.8 mL·min-1 and detection wave-length was 260 nm. The developed method was successfully applied in analysis of three different samples in-cluding O. sinensis, Hirsutella sinensis ( anamorph of O.sinensis) and Cordyceps militaris. Nine compounds were i-dentified in both O.sinensis and H.sinensis, which eight compounds were identified in C.militaris.
