Objective To evaluate the effect of non-linear blending function for dual-energy CT on image of pulmonary angiogra-phy.Methods 27 patients underwent dual energy CT pulmonary angiography(CTPA).Data obtained with 100 kVp,140kVp,and non-linear blending were divided into group A,B,and C respectively.CT value of emboli were measured.Corresponding signal to noise ratio(SNR )and contrast to noise ratio(CNR)were calculated.One-way Anova analysis and Friedman test were used to ana-lyze statistical significance among these values.Results On quantitative analysis of 27 patients,there was no statistical difference for CT value of CTPA among the three groups(P >0.05).For the noise,CNR and SNR,there were statistically significant among the three groups(P <0.05).Conclusion The non-linear blending function has certain advantages in improved image signal-to-noise ratio and it can be used in CT pulmonary angiography examination for patients suspected pulmonary embolism clinically .

Objective To explore the value of multivoxel 1H-MRS in the differential diagnosis of corpus callosum lesions.Methods 17 patients with corpus callosum lesions confirmed by clinical or pathological method underwent MRS examination.These patients included 2 cases of lymphoma,4 cases of Marchiafava-Bignami disease,3 cases of glioma, 7 cases of infarction,and 1 case of multiple sclerosis.MRS features of lesions were analyzed.Results 2 cases with corpus callosum lymphoma revealed significantly increased Cho peak, decreased Cr and NAA peak,towering Lip peak.Among 4 cases with Marchiafava-Bignami diseases, 2 cases revealed increased Cho/Cr and decreased NAA/Cr,1 case showed normal,1 case revealed inverted Lac peak.For 3 cases with corpus callosum glioma,NAA peak decreased or disappeared,and Cho peak increased in varying degrees.7 cases with corpus callosum infarction revealed significant inverted Lac peak, and NAA peak decreased in varying degrees.1 case of multiple sclerosis revealed increased Cho peak,decreased NAA peak,and inverted Lac peak during acute period with enhancement,while these features returned normal during inactive period.Conclusion Multivoxel 1H-MRS plays an important role in the differential diagnosis of corpus callosum lesions.

Objective To determine the efficacy of glucose-loweringtreatment by proton magnetic resonance spectroscopy (1H-MRS).Methods Bilateral frontal lobes of 45 male patients with type 2 diabetes mellitus (T2DM) underwent 1 H-MRS separately bythe time it was first diagnosed.Among them,30 were treated with insulin,15 were rejected.The bilateral frontal lobes of all patients were re-examined with 1 H-MRS after 6 months.The ratios of metabolites in the frontal lobe were recorded and compared,and observing whether the lactate(Lac) peak appeared or not.Results Significantly higher values of the N-acetylaspartate (NAA)/creatine (Cr)ratio and NAA/choline (Cho) ratio after 6 months (2.414 2± 0.206 6 and 2.244 2±0.341 5) were found in bilateral frontal lobes compared with pre-therapy (1.905 3±0.135 7 and 1.906 0±0.322 1)(P＜0.05).Significantly lower values of the NAA/Cr ratio and NAA/Cho ratio in the refuse treatment group(1.504 2 ± 0.262 4 and 1.510 0± 0.220 8) were found in bilateral frontal lobes compared with pre therapy (1.960 0±0.175 0 and 1.880 8±0.297 0)(P＜0.05).Lac peak was not detected in the all experiments.Conclusion 1 H-MRS provides valuable information in the assessment and evaluation of clinical efficacy and prognosis of T2DM by detecting the changes of brain metabolism.

Objective: Extracting ephedrine and berberine from the water extract of Ephedra Herba and Rhizoma Coptidis. Methods: Modified PVA was used as separating membrane and separated alkaloids. Results: A colorless ephedrine aqueous solution was obtained when extraction time was less than 8 hours; while a three constitution solution was obtained when time of extraction is over 8 hours. So is Rhizoma Coptidis. The membrane is hardly fouled. Conclusion: Purity of alkaloids from Herba Ephedra and Rhizoma Coptidis by membrane separation is Superior to that by alcoholic sediment but amount of alkaloids is reverse.

Objective To evaluate the diagnostic value of the recombinant protein Sj_Ts4 in immunodiagnosis of Schistosomiasis japonica.Methods Seventy-four blood samples of schistosomiasis japonica patients(acute, chronic and advanced)were used for evaluating the sensitivity.Blood samples from 24 Clonorchiasis patients,8 patients with hookworm infections and 30 normal persons from the areas without Schistosomiasis were used ror patients.Results The positivity rates were 97.1%(33/34),100.0%(16/16),87.5%(21/24)in rSj-Ts4-ELISA and 100%(34/34),100.0%(16/16),75.0%(18/24)in SjAWA-ELISA in acute,chmnic and advanced Schistosomiasis. respectively.Statistical analysis revealed no significant difference in sensitivity(X2=1.23,P＞0.05)between both recombinant and crude antigens.The false positive reaction was found to be 6.7%(2/30)in rSj-Ts4-ELISA and 3.3%(1/30)in SjAWA-ELISA when detected in 30 cases of normal control sera.but no statisticallv significant difference was noted(x2=0.35,P＞0.05).Twelve point five percent(3/24),20.8%(5/24)and 12.5%(1/8),37.5% (3/8),of cross-reactions were observed between rSj-Ts4-ELISA and SjAWA-ELISA for detecting the sera of patients with clonorehiasis and hookworms.There was no significant difference of cross-reaction in two parasitic infections (x2=0.60,1.33,P＞0.05)with the two tests.Conclusions The rSj-Ts4 antigen shows higher sensitivity and specificity for the diagnosis of Schistosomiasis japonica,which is helpful in the serological diagnosis of Schistosomiasis japonica in endemic areas.

This study aims to explore the differences of event-related potential (ERP) between attention deficit hyperactivity disorder (ADHD) and normal children, so that these differences provide scientific basis for the diagnosis of ADHD. Eight children were identified to be ADHD group by the diagnostic criteria of DSM-IV (diagnostic and statistical manual of mental disorders-IV), and the control group also consisted of 8 normal children. Modified visual-continuous performance test (CPT) was used as the experiment paradigm. The experiment included two major conditions, i. e. Go and NoGo. All the 16 subjects participated in the study. A high density EEG acquisition instrument was used to record the EEG signal and processed these EEG data by means of ERP and spectrum analysis. P2-N2 peak-peak value and spectral peak around 11 Hz were analyzed between ADHD subjects and those in the control group, and then statistical tests were applied to these two groups. Results showed that: (1) Under the condition of Go, ADHD group had a significant lower P2-N2 peak-peak value than the values in the control group (P < 0.05); but under the condition of NoGo there was no significant difference in between. (2) Compared with the control group, the ADHD group had significant lower spectral amplitude around 11 Hz under the condition of NoGo (P < 0.05). However, under the condition of Go the difference was insignificant. In conclusion, there is certain cognitive dysfunction in ADHD children. P2-N2 peak-peak value and spectral peak around 11 Hz could be considered as clinical evaluation indexes of ADHD children's cognitive function. These two objective indexes provide an early diagnosis and effective treatment of ADHD.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.
