Objective To investigate the association between GRM7 gene polymorphism and schizophrenia in the Uygur Chinese population.Methods rs3749380 at the GRM7 gene was selected for genotyping in a Uygur Chinese patients-control sample(case=360,control=384) by Taqman assays.The symptoms of schizophrenia were assessed by positive and negative syndrome scale(PANSS).SHEsis on line and SPSS 17.0 soft were used for calculating the data.Results For rs3749380 at GRM7 gene,the C allele frequency was 60.1％,and T allele frequency was 39.9％ in the patients.In the control,the C allele frequency was 58.6％,and T allele frequency was 41.4％.In the patients,the C/C genotype frequency was 38.6％,T/C genotype frequency was 43.1％,and T/T genotype frequency was 18.3％.In the controls,the C/C genotype frequency was 35.9％,T/C genotype frequency was 45.4％,and T/T genotype frequency was 18.7％.rs3749380 was not found to have genotypic or allelic association with schizophrenia(P＞0.05).And genotypic or allelic association with schizophrenia were not found between adolescent and adult cases,adolescent cases and controls or adult cases and controls(P＞0.05).The results showed rs3749380 genotypic or allelic was not association with schizophrenia in the different gender of the population (P＞ 0.05).The genotypes were not significantly correlated with symptoms of schizophrenia(P＞0.05).Conclusion There is no association of GRM7 gene rs3749380 polymorphism with the incidence of schizophrenia in Uygur Chinese.

Post-infectious bronchiolitis obliterans(PIBO) is a rare serious chronic lung disease characterized by irreversible small airway fibrosis.Lower respiratory infections are the most common causes in children.Its major clinical characteristics are recurrent or persistent cough, wheezing, shortness of breath, hypoxia, crackles, and persistent for above 6 weeks.Clinical diagnosis mainly depends on clinical manifestations, lung function and high-resolution CT examination.At present, there is no unified standard of treatment, mainly empirical treatment.Most of the children have a poor prognosis, and a small number of children can achieve good results through early diagnosis and intervention.

OBJECTIVE:To establish a method for the determination of 100 pesticide residues in Morus alba. METHODS:LC-MS/MS was conducted on the column of ZORBAX Eclipse plus C18 with mobile phase of acetonitrile (containing 5% water, 0.1% formic acid,5 mmol/L ammonium formate)- water(containing 0.1% formic acid,5 mmol/L ammonium formate)(gradient elution)at a flow rate of 0.4 ml/min,column temperature was 40 ℃,injection volume was 5 μl;MS conditions:ionization source was electrospray ionization with positive ion mode,scanning mode was dynamic MRM,scanning time window was 2 min;atomiz-ing gas was nitrogen,atomizing gas pressure was 40 psi,drying gas flow rate was 5 L/min,capillary voltage was 4 000 V,and ion spray voltage was 500 V. RESULTS:The linear range of 100 pesticide residues was 2.4-150 ng/ml(r>0.990 0),recovery was 69.3%-128.2%,and the determination limit was 0.003-16 μg/kg. CONCLUSIONS:The method is simple,stable and reproduc-ible,and can be used for the determination of pesticide residues in M. alba.

Raman spectroscopy is an optical technology based on the theory of Raman scattering, which is generally used in the research of medical and biological science. Raman spectroscopy can be used to detect the molecular structures and components of proteins, lipids, DNA, and other biological molecules, and provide substantial information about molecules. Thus, Raman spectroscopy is generally considered a "molecular fingerprint", and it has exceptional advantages in medical research. Moreover, this technique can reflect the changes in molecular structures and detect the alterations of chemical constituents in the samples. Raman spectroscopy, given its high sensitivity and specificity in the detection of the biological samples, has been successfully used to detect and diagnose diseases in numerous sites, such as skin, oral mucosa, breast, head, and neck. In this paper, we introduce the application of Raman spectroscopy in stomatology by conducting a review of the literature.

Objectives: To observe the efficacy of semiconducted laser photocoagulation on diabeticretinopathy(DR).　Methods: Retrospective analysis of 206 eyes from 140 patients receiving semiconducted laser photocoagulation therapy for DR.　Results:One hundred and eleven eyes were treated with PRP, 95 eyes were treated with mild-PRP. Visual acuity was increased by 1～3 lines in 82 eyes(35%), not changed in 94 eyes(46%) and decreased in 30 eyes(19%). On Fundus fluorescein angiography(FFA) 3 months later, new vessels shrinked and retinal edema recovered in most cases, but in 10 eyes, new vessels and small nonperfusional areas still could be seen after the treatment, which was treated again.　Conclusions: Timely and proper laser photocoagulation is an important treatment for DR, FFA is an essential guidance for this procedure.

Objectives:To observe the efficacy of doubling frequency laser for central retinal vein occlusion.　Methods:Twelve cases(13 eyes) of central retinal vein occlusion were treated with doubling frequency laser,4 eyes underwent panretinal photocoagulation, 9 eyes underwent regional retinal photocoagulation. The treatment varied from 1～3 times. Two cases received supplemental photocoagulation after reexamination. Fundus fluorescein angiography was performed in all the cases before and after the treatment and the results were compared.　Results:Laser spots were regular in perfusion area, pigment epithelium atrophy was mild and no fluorescein leakage was found at the border of nonperfusion area in the 9 eyes receiving regional photocoagulation treatment. Among the 4 eyes treated with panretinal photocoagulation, 2 eyes revealed neovascular atrophy at the posterior pole area; no fluorescein leakage was found and cystoid macular edema subsided. Another 2 eyes revealed neovascular regression and a little fluorescein leakage which needed supplemental photocoagulation. No neovascular increasing, perfusion area expanding or fluorescein leakage worsening were seen.　Conclusions:Laser therapy does not increase the central visual acuity but it dose help the absorption of retinal edema, hemorrhage and exudation, prevent the occurrence of proliferative vitreoretinopathy or neovascular glucoma and is protective to the present visual acuity.

To explore the relativity between alexithymia and cognitive function in somatoform disorder patients.A total of 40 patients aged 18-65 years fulfilling the criteria of ICD-10 for somatoform disorders were recruited as research group.And 40 normal healthy subjects were selected as control group.Toronto alexithymia scale-20 (TAS-20) was employed to examine the alexithymia.And cognitive abilities screening instrument (CASI) was used to measure their cognitive ability.The 9-factor scores and total score of CASI test in patients with somatoforill disorder were significantly lower than those in the normal controls (P ＜ 0.05 or ＜ 0.01).The 3-factor scores and total score of TAS-20 test in patients withsomatoforill disorder were significantly higher than those in the normal controls (P ＜ 0.05 or ＜ 0.01).In research group,CASI scores were negatively correlated with the TAS-20 scores (P ＜0.05 or 0.01).
