Objective To investigate the effects of DRD1 rs265981,rs4532,rs686 and rs265976 polymorphisms on response to clozapine in resistant schizophrenic patients.Methods DRD1 genotype was determined by SNaPshot SNP technique for 154 patients with resistant schizophrenia.Clinical symptoms were evaluated by Positive and Negative Syndrome Scale (PANSS),and the responder was defined as a reduction of 50% on PANSS score from baseline after the patients were administered orally clozapine for 8 weeks.Results The frequencies of rs265981 genotypes,alleles and rs265976 genotypes had significant differences between clozapine responder group (88 cases) and nonresponder group(66 cases) in total clinical efficacy ( x2 =10.215,P =0.004 ; x2 =4.082,P =0.041 ; x2 =14.083,P =0.007 ).The frequencies of rs265976 genotypes had significant differences between clozapine response (58 cases) and nonresponse (96 cases) to negative symptom ( x2 =9.805,P =0.046).Conclusion The polymorphisms of DRD1 gene rs265981 and rs265976 may relate with clinical response to clozapine in resistant schizophrenias.rs265981 T/T,allele T and rs265976 genotype A/A are likely to be predictive factors to the improvement of total clozapine therapeutic effects.rs265976 genotype A/A are likely to be predictive factors of negative symptom with treatment of clozapine.

Objective To understand the distributional characteristics of dystrophin gene deletion breakpoints in “central deletion hot spot” and analyze the instability of introns 44-51 after excluding the effect of intron's length. Methods Fifty-nine Duchenne/Becker muscular dystrophy(DMD/BMD) patients were detected by polymerase chain reactions with the primers to amplify exons 44-52 of dystrophin gene. The amount of actual breakpoints, expected breakpoints according to its length, and the ratios of actual breakpoints to expected values(A/E) for introns 44-51 were calculated respectively. Results In “central deletion hot spot”, about 30.8% of breakpoints fell in intron 44, about 23.1%, 17.9%, 10.3%, 10.3% of breakpoints fell in introns 50,51, 45, 48, respectively. But the amount of actual breakpoints of intron 44 was less than that of expected breakpoints according to its length, the ratio of A/E was 0.7. The amount of actual breakpoints of introns 48, 50, 51, 45 were more than that of length expected value. The ratios of A/E were 2.7, 2.0, 1.9, 1.1, respectively. Conclusion Intron 44 is more stable than the whole molecular region of “central deletion hot spot”. Introns 48, 50 and 51 are comparatively instable in “central deletion hot spot”.

OBJECTIVEStudy the effect of self-microemulsifying drug delivery system(SMEDDS) on the solubility and absorption of tanshinones to guide the selection of composition of tanshinone SMEDDS.
METHODThe solubility of tanshinones in the solution of SMEDDS was determined by UV-spectrometer and the absorption of tanshinone SMEDDS was determined by HPLC as the detection method.
RESULTThe solubility of tanshinones in solution of SMEDDS was 10 times in water and 2.5 times in micelle solution. The solubility of tanshinones in solution of SMEDDS was increased with the increasing of oil (MCT) in composition of tanshinone SMEDDS. The absorption constants (Ka) in SMEDDS and micelle solution was 0.479 h(-1) and 0.326 h(-1) respectively, and the absorption half life (t1/2) was 1.44 h and 2.12 h respectively. The absorption was increased with the oil increasing in composition of tanshinone SMEDDS.
CONCLUSIONSMEDDS can increase the solubility and absorption of tanshinones significantly and the increasing of oil content (MCT) in SMEDDS composition promote the dissolution and absorption of tanshinones.

Objective To evaluate the efficacy of MoodGYM Internet-delivered Cognitive Behavior-al Therapy in the treatment of anxiety and depression among nurses. Methods A total of 180 nurses with anxiety or depression were randomly divided into three groups,60 in each group,and 2 months of intervention with MoodGYM and health education ( once a week,30-45 minutes each time) in MoodGYM group and health education group,respectively. Another group was as a control group. Before and after intervention,De-pression Anxiety Stress Scale 21 ( DASS-21),Minnesota Satisfaction Questionnaire ( MSQ) and Subjective Happiness Scale (SHS) were used to evaluate psychological status. Results Compared with pre-interven-tion,the scores of anxiety in DASS-21 ((16. 76±7. 61) vs (9. 67±5. 78),t=21. 339,P<0. 01) and depres-sion in DASS-21 ((13. 86±7. 60) vs (10. 91±7. 12),t=16. 716,P<0. 01) decreased,meanwhile job satis-faction in MSQ((65. 11±11. 12) vs (67. 97±11. 10),t=-16. 400,P<0. 01) and subjective well-being in SHS((17. 67 ± 4. 59) vs (21. 83 ± 3. 53),t=-20. 221, P<0. 01) increased in post-intervention in the MoodGYM group. The scores of anxiety((15. 81±8. 24) vs (12. 45± 7. 68),t=17. 566,P<0. 01) and de-pression((12. 44± 8. 23) vs ( 12. 09 ± 7. 95), t=3. 934,P<0. 01) decreased, meanwhile job satisfaction ((67. 37±9. 76) vs (68. 91± 9. 67),t=-4. 474,P<0. 01) and subjective well-being(( 17. 93± 3. 80) vs (19. 85±3. 96),t=-14. 897,P<0. 01) increased in post-intervention in the health education group. After in-tervention,the effect of improving anxiety, depression, job satisfaction and subjective well-being in the MoodGYM group was more obvious than that in the health education group (P<0. 01). Conclusion -MoodGYM intervention can relieve anxiety and depression of nurses,improve their job satisfaction and sub-jective well-being.

OBJECTIVE:To analyze and compare th e contents of 6 kinds of monosaccharide in Astragalus membranaceus from different growth years . METHODS :2-4 years old A. membranaceus from three areas were extracted with water extraction and alcohol precipitation ,Sevage deproteinization to obtain A. membranaceus polysaccharide. The samples were firstly hydrolyzed with trifluoroacetic acid (TFA)and then derivatized by 1-phenyl-3-methyl-5-pyrazolone(PMP). HPLC analysis was adopted to determine the contents of 6 kinds of monosaccharide as mannose ,rhamnose,galacturonic acid ,glucose,galactose,arabinose. The determination was performed on Symmetry C 18 column with phosphate buffer solution (pH 6.8)-acetonitrile(84∶16,V/V)as mobile phase at the flow rate of 1.0 mL/min. The detection wavelength was 245 nm,and column temperature was 35 ℃. The sample size was 20 µL. RESULTS :The contents of mannose ,rhamnose,galacturonic acid ,glucose,galactose and arabinose were 0.50-0.94, 0.76-1.60,3.35-7.86,87.33-275.77,1.95-8.96,2.35-14.04 mg/g,respectively. Total contents of monosaccharide from 2,3,4 years old A. membranaceus were 98.26-139.92,173.81-295.71,122.37-182.41 mg/g,respectively. There was significant difference in the contents of glucose between 3 old years A. membranaceus and 2,4 old years A. membranaceus (162.71-275.77 mg/g vs. 87.33-107.70,111.54-167.26 mg/g,P<0.05). CONCLUSIONS :Above 6 monosaccharides are detected in 2,3,4 years old A. membranaceus,among which the content of glucose is the highest. The content of glucose in 3 years old A. membranaceus is higher than that in 2 and 4 years old A. membranaceus .
