To understand the impact of salvianolate injection treatment of liver and kidney function using different from the hospital information system nationwide 18 large three hospitals (hospital information system, HIS) to extract using salvianolate age 18-80 years-old patient, a total of 10 470 cases, depending on the treatment used to have two times before and after treatment 7 d aspartate aminotransferase (AST), alanine aminotransferase patients (ALT), serum creatinine (Cr) and blood urea nitrogen (BUN) measurement indicators grouped according salvianolate continuous use different treatment patients were divided into two groups, continuous medication time > 14 d were defined as the observation group, ≤ 14 d were defined as the control group, continuous medication longer than 31 d were not included in the analysis. Each index number of the observation group and the control group were: ALT (268/1 465), AST (270/1 585), Cr (278/1 582), BUN (278/1 611). After using propensity score methods to balance two groups of covariates, based on unweighted logistic regression logistic regression propensity score weighting combined with propensity score weighting to adjust for covariates logistic regression of liver and kidney function in the two groups were analyzed. The results showed: three logistic regression analysis showed no likelihood of ALT, AST, Cr targets two groups of patients with abnormal statistically significant difference, continuous medication time > 14 d may increase the risk of abnormal BUN indicators, comprehensive analysis still can not explain use different treatment of patients salvianolate cause liver and kidney toxicity damage, still large prospective randomized controlled trials further study.

Aim To investigate the brain targeting of ginkgolide B prodrug (PGB ) and its mechanism. Methods The liquid chromatography tandem mass spectrometry (LC-MS /MS)method was applied to in-vestigate the pharmacokinetics of PGB in rat brain tis-sue after intravenous injection of PGB.Also the brain targeting was evaluated on the basis of the pharmacoki-netic parameter of PGB.The incomplete cerebral is-chemia model was induced in mouse,the effect of PGB on cerebral capillary permeability was observed by Ev-ans blue method.High performance liquid chromatog-raphy (HPLC)was used to determine the partition co-efficients (logP)of PGB in octanol-water system.PGB and P-glycoprotein (P-gp)was docked by using Mole-gro Virtual Docker (MVD)software to predict its bind-ing abilities with P-gp.The interaction of PGB with ATPase activity of human P-gp membrane was esti-mated by measuring inorganic phosphate liberation. Results The brain targeting of PGB was evaluated by treatment effective (TA ) and drug targeting index (DTI),the calculated value were 6.87 and 4.1 4 re-spectively.Preventive medication of PGB could signifi-cantly decrease cerebral capillary permeability (P <0.05).The lipo-hydropartition coefficient of PGB was higher than that of GB,their logP data were 1 .03 and 0.61 respectively.PGB displayed the stronger binding affinity with P-gp than GB according to the molecular docking calculations,their MolDock Score toward P-gp were -1 43.36 and -1 1 6.40KJ·mol -1 respectively. ATP-hydrolisis showed that PGB increased ATPase activity with a Km of approximately 237.75 μmol · L -1 ,however GB with a Km of approximately 841 .24μmol·L -1 .PGB might interact with P-gp with a high-er affinity and exhibit more effect than GB.Conclu-sion PGB is characterized by its brain targeting. Higher liposolubility of PGB results in good blood-brain permeability,which is advantageous to its brain targe-ting.Besides,PGB can effectively inhibit the efflux effect of P-gp to GB because of its increased P-gp AT-Pase activity.

Objective To analyze the outcome of childhood B-cell acute lymphoblastic leukemia treated (ALL) with SCMC-ALL-2005 protocol. Methods Newly diagnosed B-cell ALL from May 1, 2005 to April 30, 2009 in ifve hospitals were treated and followed up according to SCMC-ALL-2005 protocol. Results A total of 601 cases with newly diagnosed B-cell ALL were enrolled. Among them, 539 cases (89.68%) were followed up until September 30, 2011. In 601 patients, there were 284 low-risk cases (LR group), 231 moderate-risk cases (MR group) and 86 high-risk cases (HR group) which were treated with SCMC-ALL-2005 protocol. The total complete remission rate during the period of induction was 98.84%and 7 cases did not achieve complete remission. The median time of the ifrst event occurring was 35 months (2.94 years). Among 539 cases completing follow-up, 403 cases (74.77%) completed treatment including 223 cases (86.43%) in LR group, 150 cases (73.17%) in MR group and 30 cases (39.47%) in HR group. The rate of cases completing treatment was signiifcantly different among three groups (P=0.001). The completion rate was highest in LR group and lowest in HR group. The 3-year overall survival (OS) rate was (83.3±1.8)%, and the 3-year EFS (event-free survival) rate was (79.2±1.9)%using a Kaplan-Meier method. The 5-year OS rate was (79.5±3.3)%, and the 5-year EFS rate was (70.9±3.7)%. There were signiifcant differences in 3-year EFS rate and 5-year EFS rate among three groups (P<0.05). Conclusions Childhood B-ALL treated with SCMC-ALL-2005 protocol achieved a better therapeutic effect and prognosis. The multi-center collaborative research is useful for the standard treatment of ALL.
