OBJECTIVE:To evaluate the association between UGT1A1 gene polymorphism and irinotecan-induced 3-4 degree neutropenia,and to provide evidenced-based reference for clinical treatment. METHODS:Retrieved from CJFD,Wanfang data-base,VIP,PubMed,EMBase,Science direct and Cochrane library,related studies about UGT1A1*28 and UGT1A1*6 gene polymorphism and irinotecan-induced 3-4 degree neutropenia were collected. After data extraction and quality evaluation of included studies,Meta-analysis was conducted by using Review Man 5.3 software. RESULTS:A total of 29 studies were included,involv-ing 2408 patients. UGT1A1*28 includ wild genotype TA 6/6(UGT1A1*1/*1)and mutations genotype TA 6/7(UGT1A1*1/*28)、TA 7/7(UGT1A1*28/*28),UGT1A1*6 includ wild genotype GG and mutations genotype GA、AA. Results of Meta-analysis showed:the incidence of 3-4 degree neutropenia in UGT1A1*28 and UGT1A1*6 mutations genotype were significantly higher than wild genotype,with statistical significance [UGT1A1*28:OR=1.92,95%CI(1.52,2.44),P<0.001;UGT1A1*6:OR=2.49, 95%CI(1.46,4.26),P<0.001]. Using medium-dose and high-dose of irinotecan,the incidence of 3-4 degree neutropenia in UGT1A1*28 and UGT1A1*6 mutations genotype were significantly higher than wild genotype,with statistical significance [UGT1A1*28:OR=2.06,95%CI(1.57,2.70),P<0.001);UGT1A1*6:OR=1.92,95%CI(1.35,2.74),P<0.001]. Using low-dose of irinotecan,there was no statistical significance in the incidence of 3-4 degree neutropenia between UGT1A1*28,UGT1A1*6 mutations genotype and wild genotype [UGT1A1*28:OR=1.20,95%CI(0.70,2.08),P=0.51;UGT1A1*6:OR=3.19,95%CI (0.85,11.89),P=0.08]. CONCLUSIONS:Using medium-dose and high-dose of irinotecan,UGT1A1*28 and UGT1A1*6 muta-tions will increase the risk of severe neutropenia in cancer patients. Using low-dose of irinotecan,there is no clear correlation be-tween gene polymorphism and the neutropenia.

Objective To investigate the variations of polysomnography of the patients with retardative depression and non-retardative depression. Methods Twenty-eight patients with depression without any medicine at least for 1 month and fifteen normal controls were assessed in this study. Based on the scores of retardation of Hamilton Depression Scale( HAMD), the patients were divided into the group of retardative depression and the group of non-retardative depression. Polysomnography was given to all the subjects. Results Compared with the normal controls, the depressive patients both in the retardative depression group and in the non-retardative depression group showed significant differences of lower total sleep time (TST), sleep efficiency (SE), SWS% , rapid eye movement ) sleep time ( RT), REM sleep latency (RL) ( all P ＜ 0. 05 ), and higher sleep latency (SL) , awakening time( AT), awakening number( AN ), the percentage of AT( A/TST% ), the percentage of 1 sleep( S1 % ), the percentage of RT( RT% ), REM activity ( RA), and REM intensity (RI). REM density (RD) in the retardative depression group was significantly higher than both the non-retardative depression group and the control group ( t =2.36, P＜ 0. 05; t = 2.75, P＜ 0. 05 ). Conclusion Abnormalities of PSG in depression are proved, and RD may be relative to retardation. The differences of PSG do not existed between different kinds of depression such as retardative depression and non-retardative depression.

Objective To identify the metabolic alterations in the prefrontal lobe in male patients with schizophrenia by proton magnetic resonance spectroscopy (~1H-MRS), and to study the relationship between metabolic alterations and executive function. Methods The study was conducted in 26 male schizophrenics with medicine-free for at least 7 days and 28 normal controls. A multi-voxel ~1H-MRS on the prefrontal lobe was performed in all the subjects within 24 hours of admission. Wisconsin Card Sorting Test (WCST) was used to evaluate executive function. The NAA, Cho and Cr were measured and the ratios of NAA/Cr, Cho/Cr and NAA/(Cho+Cr) were calculated. Results Compared with normal controls, the patients demonstrated significantly lower NAA/Cr ratio (t=2.93, P<0.01) in the left prefrontal lobe and poorer performance in WCST (P<0.05). The NAA/Cr ratio in the left prefrontal lobe was positively associated with the responses errors and the perseverative errors of WCST(r=0.45, P＜0.05; r=0.47, P＜0.05)and negatively associated with the categories completed and conceptual level responses(r=-0.54, P＜0.01; r=-0.56, P＜0.01). Conclusions Abnormalities in neuronal function and/or integrity are present in the left prefrontal lobe of male schizophrenics. The neuron damage in the left prefrontal lobe of male schizophrenic may be the primary cause of cognition dysfunction.

ObjectivesTo explore the characteristic of different subtypes of depression on prefrontal lobe and hippocampus by proton magnetic resonance spectroscopy (1H-MRS),and its relationship.Methods 46 patients of depression,which were met with the third edition of the Chinese Classification of Mental Disorders (CC-MD-Ⅲ ) since December 2010 to March 2012 from Mental Diseases Prevention and Treatment Institute,were examined at prefrontal lobe and hippocampus by multi-voxel 1 H-MRS.They were divided into male ( n =25) and female ( n =21 ),early-onset subtype ( n =26) and late-onset subtype ( n =20 ),short-duration of illness ( n =23 )and long-duration of illness ( n =23 ) by different criteria.The N-acetylaspartate ( NAA),Choline-congtaining compounds (Cho),and Creatine compounds (Cr) were measured and the ratios of NAA/Cr,Cho/Cr were determined.ResultsOn left prefrontal lobe,the NAA/Cr ratios in patients of male ( 1.83 ± 0.19),late-onset subtype (1.86 ±0.16),and short-duration of illness ( 1.83 ±0.17) showed higher than those in female ( 1.70 ±0.12,t=2.711,P ＜ 0.01 ),early-onset subtype ( 1.70 ± 0.19,t =3.028,P ＜ 0.01 ),and long-duration of illness ( 1.71±0.20,t =2.192,P＜0.05).Both on left prefrontal and on left thalamus,the ratios of NAA/Cr were positively correlated with the age of onset ( r=0.493 and 0.478,P＜0.01 ),and were negatively correlated with the duration of illness ( r =- 0.482 and - 0.470,P ＜ 0.01 ).ConclusionsDifferent subtypes of depression maybe have different characteristics of 1H-MRS due to the age of onset and the duration of illness.
