With the advance of drug development and research techniques, the drug metabolic processes and mechanism can be more deeply achieved. As the drug metabolism and pharmacokinetics process are mediated by drug metabolizing enzymes and transporters, study of drug metabolizing enzymes and transporters has become an important part for drug development. The traditional immunoassays with low sensitivity and poor specificity can not reflect the accurate expression level of drug metabolizing enzymes and transporters. We now give a brief review on the quantitative study of drug metabolizing enzymes and transporters by mass spectrometry-based proteomic approach.

Objective To discuss the distribution laws of TCM syndromes of early threatened abortion; To analyze the related factors of pregnancy outcome of early threatened abortion. Methods The study included 1010 hospital patients who were diagnosed as early threatened abortion. Excel2010 was used to establish database in order to collect general information such as the age, menstrual history, times of abortion and adverse pregnancy, incidence of solar term and pregnancy week, the type of TCM syndromes and the pregnancy outcome (at least 3 months after being out of hospital) of patients. The distribution laws of TCM syndromes, and related factors of pregnancy outcome were analyzed. Results Among the 1010 cases, 762 cases were with kidney deficiency syndrome (75.4%); followed by blood heat syndrome, a total of 178 cases, accounting for 17.6%; qi and blood deficiency syndrome, a total of 40 cases, accounting for 4%; blood stasis syndrome, a total of 15 cases, accounting for 1.5%; liver stagnation syndrome, a total of 15 cases, accounting for 1.5%. The distribution of TCM syndromes was statistical significance in the different age groups and the incidence of pregnancy week (P<0.01). But there was no statistical significance in menstrual history, times of abortion, times of adverse pregnancy, and the incidence of solar term (P>0.05). Among the 1010 cases, follow-up to 698 cases, 567 cases were successful pregnancies, accounting for 81.2% of the follow-up of patients; 131 cases were failed pregnancies, accounting for 18.8% of the follow-up of patients. In the study, it found that there was statistical significance between different age groups and pregnancy outcomes (P=0.026). The pregnancy outcomes were related to the age groups (P=0.012, OR=1.063), and it was not related to TCM syndromes, times of abortion, times of adverse pregnancy, menstruation, pregnancy week. Conclusion Kidney deficiency syndrome is the main syndrome of early threatened abortion. The distribution of TCM syndromes is related to the age group and the incidence of pregnancy week of patients. Age of patients is the related factor affecting the pregnancy outcome.

Objective To investigate the correlation between asymmetric dimethylarginine (AD-MA) and endothelial dysfunction in patients with uremia.Methods Uremic patients who did not receive hemodialysis were defined as A group (n =40) ; uremic patients who had received hemodialysis were divided into B group (n =45) ;healthy people were defined as C group (n =20) ;and chronic kidney disease (stage 2 ～ 4) patients were defined as D group (n =20).The diameter of intima-media thickness,and endothelium-dependent or independent dilation (EDD or EID) of radial artery in right forearm were detected with diasonography.The levels of ADMA were determined by high-performance liquid chromatography.Results Compared to C group,the levels of ADMA in A,B and D groups were significantly increased [C:(0.78 ±0.19) μmol/L,A:(1.51 ±0.16) μ mol/L,B:(1.13 ±0.14) μmol/L,D:(0.92 ±0.11) μmol/L; P ＜0.05].Compared to A group,the levels of ADMA were significantly decreased in B group (P ＜0.05).EDD and EID were decreased significantly in A,B and D groups compared to C group [EDD:C:(13.52±1.73)％ vs A:(7.32 ±0.54)％,B:(9.02 ±0.86)％,D:(10.13 ±1.25)％,P ＜0.05;EID:C:(14.45±1.85)％ vsA:(10.37 ±1.51)％,B:(9.54±1.39)％,D:(11.17±1.56)％,P ＜0.05].EDD in B group was significantly lower than A group (P ＜0.05).In group A,a negative correlation was found between EDD and the level of ADMA (r =-0.81,P =0.020).Conclusions ADMA level was significantly increased in uremic patients.A close correlation existed between ADMA and endothelial dysfunction of radial artery.

Objective:To determine the derivative chromosome 9 by the method of detecting the ASS gene,and to explore the relationship between the deletion of derivative chromosome 9 and the efficacy and prognosis of the chronic myeloid leukemia (CML)patients. Methods:The materials of 34 CML patients with positive BCR-ABL fusion gene whose ASS genes were detected were retrospectively analyzed. All patients were treated with Extra-signal (ES)probe to detect the derivative chromosome 9.All patients were divided into two groups according to whether they carried the derivative chromosome 9.The blastic phase or the accelerated phase rates in two groups were compared by using Fisher exact probability. Results:All patients were detected by FISH (BCR-ABL ES probe),and all the BCR-ABL fusion signals were positive.6 of 34 patients were found the deletion of ASS gene, among them 1 case blonged to chronic phase,and 5 cases developed into blastic phase or accelerated phase. In the patients without ASS gene deletion,there were 22 cases in chronic phase,and 6 cases in plastic phase or accelerate phase,there was significant difference of blastic phase rate/accelated phase rate between them (P<0.05).A total of 26 patients were treated with tyrosine kinase inhibitors (TKI).5 of 26 patients belonged to the ASS gene deletion group,1 of 5 patients treated with TKI got molecular remission,4 of 5 patients developed into blastic phase or accelerated phase.21 of 26 patients belonged to the group without ASS gene deletion,and among them,19 cases got molecular remission,2 cases developed into plastic phase or accelerated phase after treatment of TKI,there was significant difference between them (P < 0.05 ). 6 patients were treated with traditional chemotherapy (hydroxyurea,interferon);1 of 6 patients belonged to the ASS gene deletion group,finally developed into the blastic phase or accelerated phase;5 of 6 patients belonged to the group without ASS gene deletion,2 cases got the hematological remission,and 3 patients developed into blastic phase or accelerated phase after treatment,and there was no significant difference of blastic phase rate/ accelerated phase rate between them (P > 0.05 ). Conclusion:The CML patients with derivative chromosome 9 (ASS gene deletion)prone to get disease progression, and have a higher proportion in the blastic phase or accelerated phase patients.Derivative chromosome 9 is related to the bad treatment efficacy of TKI and the poor prognosis of CML.

OBJECTIVETo compare therapeutic effects between suspine rotation and flexion manipulation for treating lumbar disc herniation.

METHODSFrom December 2008 to January 2011, 134 patients with lumbar disc herniation were treated, including 74 males and 60 females,ranging in age from 17 to 67 years,33 patients with age over 50 years old. According to diagnosis the ladder of the 9 cases bulging type, 74 hernia type, 51 cases free type. The patients were randomly divided into treatment group ( 69 cases) and control group (65 cases). All the patients were treated with the three-dimensional computer-controlled traction therapeutic apparatus,with continued traction for 20 minutes. After traction, flexion manipulation and rotat-ing manipulation were respectively adopted in treatment group and control group (on alternate days one time, 3 times as a course of treatment). The symptoms and signs (including back pain and discomfort, lower limb pain and numbness, powerless urination and defecation,numbness in perineum, straight-leg raising degree,ability of lower extremity walking,work and live) of patients were observed after treatment.

RESULTSAll patients were followed up for 0.5 to 6 months with an average of 1.1 months. After treatment, the symptoms and signs of patients have significantly improved (P < 0.01), but the symptomes of powerless urination and defecation,numbness in perineum was not improved obviously (P>0.05). Forty-two of 69 patients in treatment group got excellent result, moderate in 20, poor in 7; Twenty of 65 patients in control group got excellent result, moderate in 25,poor in 20.

CONCLUSIONThe whole effect of lumbar backwards rotation manipulation is more satisfactory than flexsion manipulation for treating lumbar intervertebral disc herniation. But spinning force and times should be noticed.
