The dysfunction of response inhibition is possible an index to discriminate the subtypes of ADHD.

Objective To analyze the difference of frontal-cingulate functional connection between patients with major depression and healthy controls in recognization of sad facial expression, and discuss the neutral basis of emotional bias in preliminary. Methods 12 female patients with major depression and 12 matched healthy controls were scanned. The intensities of brain activation in the process of sad and neutral facial expression recognition were analyzed, and the strengths of frontal-cingulate functional connection were compared between the two groups based on dynamic causal modeling. Results Comparing the stimulus adjusting connection models with Bayesian model indicated that model Ⅱ matched with the observation data better. In the comparison between model Ⅱ and model I ,the average Bayes factor was more than 7.38. In the comparison between model Ⅱ and model Ⅲ,the average Bayes factor was more than 2.71. Calculating the intrinsic connection parameters and stimulus adjusting connection parameters based on intrinsic connection model and stimulus adjusting connection model( model Ⅱ ), the result showed that connection strength between anterior cingulate and right inferior frontal gyrus in depression was greater than that in healthy controls. Conclusion The frontal-cingulate functional connection of patients with major depression is increased abnormally ,which may be the neural basis of negative emotional bias.

Aim:To develop a practical chiral CE method for the quantitative determination of the unwanted enantiomer[( R )-enantiomer]presented in zolmitriptan. Methods:The background electrolyte was 20 mmol/L sodium dihydrogenphosphate solution with 1% S-β-CD,adjusted to pH 3.50 with phosphoric acid. A fused-silica capillary(60 cm×50 μm ID,effective length 51.5 cm)was used at 20 ℃ for the separation. The applied voltage was -30 kV. The samples were loaded by hydrodynamic injection(50 mbar pressure,6 s). UV was measured at 220 nm. Results:Zolmitriptan and its chiral impurity were baseline resolved ( R s=6.66). The linearity was good over the concentration range from 4 to 80 μg/mL( r =0.999 8) of ( R )-enantiomer. The injection precision (expressed as CV%) was 2.83%. The average recovery was 99.97%( n =9). The limit of detection was 1.5 μg/mL. The host-guest complex binding constants were 964 and 905 mol-1 for ( R )-enantiomer and zolmitriptan,respectively. Conclusion:The method is suitable for the determination of ( R )-enantiomer in zolmitriptan and binding constants of zolmitriptan enantiomers to S-β-CD.

ObjectiveTo explore the genetic impact of TPH1 A218C,MAOA-uVNTR on abnormal frontal lobe of depressed patients and the interactions between the two polymorphisms using the method of genetic imaging.Methods28 patients with major depression and 34 healthy controls which were equal in sex,age,years of education and had negative family history of mental illness were recruited in our study.All paticipants underwent functional Magnetic Resonance Imaging (FMRI) in negative emotion recognition and were divided into different genotypes.Then frontal lobe was extracted as region of interest by WFU software into six subregions-bilateral superior frontal lobe,middle frontal lobe and inferior frontal lobe.ResultsPatients (0.19 ± 0.01 ) and controls (0.15± 0.05 ) with TPH1 AA genotype showed increased activation in left inferior frontal lobe than patients and controls with AC or CC genot.Patients with AA genotype showed increased activation in right inferior frontal gyrus(0.28 ±0.07) than other five groups as well.Patients with MAOA-H genotype showed increased activation in right middle frontal gyrus(0.15 ±0.06),left inferior frontal gyrus(0.18±0.02) than patients and controls with L genotype.Superimposition of TPH1 A218C and MAOA-uVNTR exsited in abnormal function of left inferior frontal gyrus(F=4.98,P =0.047 ).Patients with AA and H genotype showed increased activation in this area significantly than other patient group.ConclusionDifferent genes in serotonin system can affect brain function through a common 5-HT feature.

ObjectiveTo investigate the expressions of folate receptor alpha (FOLR1) in 40 esophageal cancerous tissues and its relevance of ABO blood group.MethodsABO blood groups were analyzed in 40 patients.Immunohistochemistry (IHC) and real-time quantitative reverse transcription PCR detection were used to detect the expression of folate receptor in cancer and adjacent tissues.Results20％of esophageal cancer was suspected positive (+), 50％ of cancer adjacent tissue was suspected positive (+), 10％ were positive (+), the difference was statistically significant (x2 = 14.48, P ＜0.01).Real Time RT-PCR analysis showed FOLRI low expression in esophageal cancer and adjacent tissues, compared to normal esophageal mucosa, the differences were statistically significant (F1 =53.247, F2 = 116.500, P ＜0.01).ABO blood type and FOLRi in esophageal cancer patients were not significant correlated (P =0.647, P ＞0.05).ConclusionsFOLRI expression was decreased in the esophageal lesions compared with adjacent tissues.Detection of FOLRl expression level in esophageal cancerous tissues and the paired adjacent tissues was helpful for judging the extent of disease and guiding surgery treatment.The FOLRI expression level in esophageal carcinoma tissues had no relationship with ABO blood types.
