China Pharmacy 2005;0(17):-
OBJECTIVE:To develop a HPLC-ECD method for the determination of scutellarin in human plasma.METH-ODS:The plasma sample injection was performed after protein precipitation by methanol.The mobile phase consisted of 0.083mol? L-1 sodium dihydrogen phosphate-methanol-acetonitrile-tetrahydrofuran(60:30:10:0.4),which was added dropwise with H3PO4 in a ratio of 100:106).The column temperature was under room temperature;the detection voltage was 100mV;the protection voltage was 500mV;the flow rate was 1mL? min-1 and the sample size was 20? L.RESULTS:The calib-ration curve was linear in the range of 20.0~ 400.0?g? L-1(r=0.999 9).The methodological recovery was 96.79% ~ 108.50%.Both the intra-day and inter-day RSD were less than 5%.CONCLUSION:This HPLC-ECD method is accurate,sensitive and simple,and suitable for pharmacokinetic study of scutellarin.

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 evaluate the effects of 6-week atypical antipsychotics treatment on serum brain-derived neurotrophic factor (BDNF)level,and the correlation between BDNF level and clinical efficiency in first-episode antipsychotic-na?ve schizophrenia.Methods We recruited 39 hospitalized patients with first-episode antipsychotic-na?ve schizophrenia that met with Diagnostic and Statistical Manual of Mental Disorders—4th Edition (DSM-IV).Both Positive and Negative Syndrome Scale (PANSS)and the level of serum BDNF were measured before and after 6 weeks’treatment with atypical antipsychotics.We also studied 30 healthy controls.Serum BDNF was assayed at baseline.Results Pre-treatment BDNF level was significantly lower in the schizophrenic patients than in the controls [(6.82±2.1 5 )μg/L vs .(1 1.6 ± 3.32 )μg/L,t = 7.239,P < 0.001 ].Although BDNF level increased with treatment (t =2.349,P =0.021)in the schizophrenics,post-treatment BDNF level was still lower than in the normal controls (t =4.634,P <0.001).After 6 weeks’treatment for schizophrenia,the total score of PANSS,the scores of positive and negative symptoms,and the score of general psychopathology scale were all decreased (t =6.1 64,P < 0.001;t = 4.520,P < 0.001;t = 4.132,P < 0.001;t = 5.142,P < 0.001 ).Pre-treatment BDNF levels were directly correlated not only with the rate of decreased PANSS total score (r =0.348, P <0.05),but also with the rate of decreased negative symptoms score (r = 0.35 1,P < 0.05 ).However,pre-treatment BDNF levels were not correlated with improved positive symptoms,general psychopathology (r =0.204, 0.186,P >0.05),or duration of illness (r = - 0.058,P > 0.05 ).Changes in BDNF levels with treatment were correlated with the duration of illness (r =-0.345,P <0.05),but not with psychiatric improvement (r =0.036-0.1 74,P >0.05).Conclusion BDNF level is significantly lower in patients with first-episode antipsychotic-na?ve schizophrenia than in normal controls.It could be improved by using antipsychotics.Higher pre-treatment BDNF level may predict better response to antipsychotics.

Objective To compare with the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) between the left and the right prefrontal on refractory negative symptoms and serum brain-derived neurotrophic factor (BDNF). Methods 80 hospitalized schizophrenics with refractory negative symptoms were divided into study group (n=40) and control group (n=40) randomly. Both groups were received 4-week treatment of 10 Hz rTMS. The stimulus lo?cation of the study group was the left prefrontal, and the control group was the right prefrontal. The type and dose of anti?psychotics remained unchanged during the treatment. The evaluation of positive and negative symptom scale (PANSS) and the measurement of BDNF concentration before treatment and after 4 weeks treatment was analyzed. Results Com?pared with before treatment, the total score of PANSS after treatment significantly decreased (P<0.05) both in the study group [(71.2±13.8) vs. (63.3±11.4)] and the control group [(70.3±13.4) vs. (63.7±12.2)]. The score of negative symptoms in the study group decreased [(22.8±6.6) vs. (18.4±5.9), P<0.01]. The BDNF concentration increased in the study group ](6.78±2.16) vs. (8.74±2.76)] and the control group [(6.83±2.32) vs. (8.66±2.70)]. Conclusion 10Hz rTMS on the left pre?frontal combined with drugs are helpful to improve the refractory negative symptom of the patients with schizophrenia. Stimulation on both left and right prefrontal lobe could increase serum BDNF concentration.
