A chiral LC-MS/MS method for the simultaneous analysis of desvenlafaxine (DVS) enantiomers in human plasma was developed and applied to a pharmacokinetic study on 12 Chinese healthy volunteers. d6-Desvenlafaxine was used as internal standard (IS). Chromatographic separation was performed on the Astec Chirobiotic V chiral column (150 mm x 4.6 mm, 5 μm). The assay was linear over the concentration range of 0.500-150 ng x mL(-1) for both enantiomers (r2 > 0.99). The method was successfully applied to a stereoselective pharmacokinetic study of 100 mg desvenlafaxine sustained release tablets on 12 Chinese healthy volunteers under fasting conditions. The results showed that the pharmacokinetic parameters were similar to both enantiomers in Chinese healthy volunteers. The AUC(0-t), and C(max) of the two enantiomers were about 1.5 times higher than those of blacks and whites reported in the literature.

Objective To analyze the distribution characteristics of blood uric acid and its relationship with the risk factors of metabolic syndrome in Uygur.Methods The questionnaire,anthropometric measurements,and biochemical detection were carried out in 4 428 healthy Uygur subjects in Xinjiang Urumqi and Kashi hospitals.Results (1) The prevalences of hyperuricemia and metabolic syndrome were 21.3 ％ and 8.2％,respectively.With the increased blood uric acid level,the incidences of coronary heart disease,hyperglycemia,hypertension,central obesity,and dyslipidemia were raised.Blood pressure,blood glucose,HbA1c,triglyceride,total cholesterol,apolipoprotein A,low density lipoprotein-cholesterol,body mass index (BMI),and waist to hip ratio (WHR) were increased with increased uric acid level,while high density lipoprotein-cholesterol was decreased.(2) The incidence of hyperuricemia was increased further when the number of metabolic syndrome components was accumulated (P＜0.01).With the increase of uric acid level,the prevalence of metablic syndrome gradually raised (P＜0.01).(3) Multiple logistic regression analysis showed that WHR (OR =7.639,95 ％ CI 1.744-33.466),coronary heart disease (OR =2.784,95 ％ CI 1.718-4.510),hyperuricemia (OR =2.155,95 ％ CI 1.457-3.188),smoking (OR =1.437,95％ CI 1.071-1.927),family history of metabolic diseases (OR =1.333,95％ CI 1.044-1.703),occupational pressure (OR =1.290,95 ％ CI1.021-1.631),and BMI (OR =1.146,95 ％ CI 1.112-1.181) were the risk factors of metabolic syndrome.Exercise (OR=0.472,95％ CI0.370-0.604) and low salt diet (OR=0.793,95％ CI0.662-0.949) were the protective factors.Conclusion Serum uric acid level is correlated with a variety of metabolic parameters.With the increased uric acid level,the risk of multiple metabolic abnormality was increased.Comprehensive prevention and control should be taken for the reduction of the risk factors and much attention should be paid to the adverse effects of hyperuricemia.

ObjectiveTo compare the effects of Qishen Fukang capsules and Fluoxetine on cognitive function in first-episode depressions.MethodsBetween December 2011 and January 2012,63 depressed patients with first-episode from Center for Mental Disease Control and Prevention of Third Hospital of PLA were enrolled,and were divided randomly into the Qishen Fukang capsules-treated group ( Chinese medicine group,CMG,31 cases) and fluoxetine treated group (Western medicine group,WMG,32 cases; Jiangsu changzhou pharmaceutical Co.,LTD production) by the method of the random number table.The therapeutic dose was oral 0.2～0.6 g (three times/d) for each CMG patient,and morning oral 20～40 (20 ± 5) mg/d for each WMG patient.Meanwhile,each patient was given the short - term small dosesof benzodiazepine drugs,but no other antidepressants.Each patient and control was assessed with 17-item Hamilton Depression Scale (HAMD).A total of 32 healthy subjects were involved as control group.Each patient was measured with evoked event-related potential P300 change before and after 6 weeks treatment.And compared the effects of Qishen Fukang capsules and Fluoxetine on cognitive function in first-episode depressions before and after treatment.Results(1) Compared with prior-treatment [ CMG ( 29.1 ± 5.1 )score vs WMG(29.0 ± 4.5)score],the HAMD scores of post-treatment [ CMG( 10.1 ± 3.2) score vs WMG (12.3 ± 3.4) score] were decreased significantly ( P＜0.05).The HAMD scores in CMG were significantly lower than the WMG( P＜0.05).The HAMD reductive rate in CMG was significantly higher than the WMG [ (65.6 ± 2.1 ) ％ vs (57.9 ± 3.2 ) ％,P ＜ 0.05 ].(2)compared with prior-treatment,the latency periods of post-treatment were shortened[ P2 (152.8 ± 54.1)ms vs (208.9 ± 57.6)ms,(174.5 ±63.2)ms vs (207.3 ± 55.8) ms;N2(208.7 ± 57.9)ms vs (273.4 ± 62.0) ms,(239.2 ± 59.2) ms vs (275.6 ± 60.8)ms; P3(319.1 ±60.2)ms vs (396.3 ± 66.3)ms,(315.6 ± 61.1)ms vs (394.7 ±55.6)ms ],while the amplitudes were prolonged [ P2 (7.8 ± 1.7 ) μV vs ( 3.3 ± 1.2 ) μV,( 7.0 ± 1.4 ) μV vs　(3.4±1.4)μV; N2 (3.6±1.4)μV vs (1,0±0.7)μV,(2.4±1.3)μV vs (1.2 ± 1.0)μV; P3 (9.6±2.2)μV vs (4.5 ± 1.0)μV,(7.5 ±2.2)μV vs (4.6 ± 1.2)μV] in the CMG and WMG (all　P ＜0.05).Compared with the CMG,the latency periods of F2,and N2 were signiflcantly longer (all P ＜ 0.05 ),and the latency period of p3 was no difference ( P＞0.05 ),and the amplitudes of N2,and P3 were lower ( all P ＜ 0.05 ),and the amplitude of P2 was no difference ( P＞0.05 ) in the post-treatment of WMG.(3)Compared with the controls,the latency periods of P2,N2,and P3 were shortened,while the amplitudes were prolonged in the post-treatment of CMG and WMG ( all P ＜ 0.05 ).The latency periods and amplitudes of P2,N2,and P3 did not show any difference in the CMG after treatment ( all P ＞ 0.05).The latency period of P2,and N2 were still significantly longer (all＜0.05) and the latency period of P3 was no difference ( P＞0.05) while the amplitude of P2,N2,and P3 were still significantly lower (all P ＜ 0.05) in the post-treatment of WMG.ConclusionsQishen Fukang capsules and Fluoxetine can improve significantly cognitive function in first-episode depressions.Qishen Fukang capsules is superior to fluoxetine on improving the early preparation efficiency of information processing.

GM-CSF product from the monoclone GM-CSF-K-562 cell lines was quantified using ELISA method. Results We successfully constructed the hGM-CSF eukaryocyte expressing plasmid and hGM-CSF expressing K-562 cell line. Conclusion The construction of K-562/GM-CSF line will simplify the preparation of tumor vaccine, thus facilitating the application of tumor vaccination therapy in clinical application.

Objective To study the clinic effect and safety of MEAD chemotherapy regimen for adult patients with relapsed or refractory acute lymphocyte leukemia. Methods Between July 2006 and July 2009,twenty-two adult patients with relapsed or refractory acute lymphocyte leukemia received MEAD regimen (mitoxantrone 6 mg/d dl-3 iv drip,cytarabine 100 mg/d dl-5 iv drip,etoposide 100 mg/d dl-5 iv drip,dexmethasone 10 mg/d dl-8 iv drip). Results The complete remission (CR) rate of adult patients with relapsed or refractory acute lymphocyte leukemia was 31.8 %,the partial remission(PR) rate was 22.7 % and the overall response (OR) rate 54.5 %. The cumulitive CR rate was 50.0 %,and the PR rate 40.9 % after two times MEAD chemotherapy regimen. The main adverse effect was different level of myelosuppression,and other toxicity of vital organ was mild. Conclusion MEAD regimen is effective and can be tolerated for adult patients with relapsed or refractory acute lymphocyte leukemia,and its side effect is mild.

Objective To investigate the expression level and clinical significance of WT1 gene in acute luekemia (AL) patients.Methods WT1 gene level was detected by real time quantitative-polymerase chain reaction in acute myelogenous leukemia (AML) and in acute lymphocytic leukemia (ALL) patients.Then the expression levels of WT1 gene in different subtypes of AML were compared,and the correlation between gene expression and disease courses and prognosis were observed.Moreover,the relationship between disease courses and WT1 expression in patiens after receiving haemopoietic stem cell transplantation were analyzed.Results Among 66 cases,WT1 expression positive rate was 87.5 ％ (14/16) in AML and 76.0 ％ (38/50) in ALL.In AML,the expression level in M3 showed the lowest than that in any other subtypes (compared with M1,M2,M4,M5,P value was 0.040,0.007,0.006 and 0.01,respectively).The expression level of WT1 was closely correlated with leukemia disease courses.The expression level in complete remission (CR) group showed a significant lower expression level than that in non-remission group (P =0.018) and relapse group (P =0.003),and the re-increase of WT1 expression level could predict relapse as early as 1.5 months.Moreover,WT1 expression also showed an close relationship with prognosis of patients receiving haemopoietic stem cell transplantation.Patients whose WT1 was undetectable had a better prognosis than those with persistent expression,and increase again after becoming undetectable.Conclusion WT1 has a high expression level in AL,which can represent minimal residual disease.The expression level in M3 was lowest than that in different AML subtypes,and its expression level has a close correlation with clinical disease course and prognosis of AL.

[Objective]To discuss the clinical effect of fludarabine and busulfan (Bu+Flu) as a low toxicity myeloablative conditioning regimen for allogeneic peripheral blood stem cell transplantation (allo-HSCT)in leukemia patients.[Methods]Clinical data of 13 patients with hematological malignancies receiving conditioning regimen with Bu+Flu for allo-HSCT were analyzed retrospectively.Conditioning regimen was Bu+Flu,compalriot mismatched and unrelated transplantation combined with rabbit anti-human thymocytes immune globulin (ATG).CsA+short course of methotrexate or CsA + mycophenolate mofetil were used to prevent graft-versus-host disease (GVHD).DNA sequencing of short tandem repeat (STR)polymorphism analysis method was performed for identification of donor stem cells implantation.[Results]13 patients all tolerated with this conditioning regimen well,no serious complications occurred.Neutrophil engraftment was at 9-15 days (median 11 days),platelet engraftment at 8-25 days (median 13 days).10 patients achieved hematopoiesis reconstitution with their full donor chimerisms confirmed by STR-DNA analysis.Acute GVHD occurred in 5 cases,accounting for 38.5％.Chronic GVHD occurred in 4 cases of 10 patients could be assessed,accounting for 40.0％.Severe GVHD more than Ⅱ degree did not happen.1-39 months (median time 11 months)of follow-up revealed the overall survival rate of 76.9％(10/13),disease-free survival of 61.5％ (8/13).The causes for death were relapse in all.[Conclusion]The conditioning regimen with Bu+Flu has low toxicity,well tolerance and better effect.
