Metabonomics is an emerging platform for technology.It provides a new method in study of drugs.This article summarized evidences derived from recent metabonomics studies regarding hypoglycemic drugs.We collected all proofs of body metabolite profiling in assessing drugs and exploring their potential mechanisms.An outlook of metabonomics for future research into hypoglycemic drugs was also postulated.

Trastuzumab is one of the most important drugs for HER2 overexpressing breast cancer patients. However, even for these patients, the objective response rates to trastuzumab monotherapy are 12%-34%, and the median duration is about 9 months. Many patients progress within 12 months. Study of the mechanisms of resistance to trastuzumab will help us fi nd some new drugs and methods to overcome or delay the resistance.

Adipocyte fatty acid binding protein (AFABP) is a member of fatty acid binding protein superfamily.Studies in the relationship between AFABP and atherosclerosis may provide new ideas for its pathogenesis.This review summarised a concise and general overview of AFABP' s role in atherosclerosis and atherosclerosis-related disease.

OBJECTIVE To evaluate the role of real-time fluorescent quantitative PCR assay in the early diagnosis of invasive aspergillosisi(IA) after allo-hematopoietic stem cell transplantation.METHODS All 123 serum samples from 18 IA patients and 38 no-invasive fungal infection(IFI) patients were detected by TaqMan-based real-time PCR to explore the cutoff of this array,while the primer and probe could amplificate five major Aspergillus species including A.fumigatus,A.flavus,A.niger,A.terreus and A.oryzae.RESULTS The optimal value could be acheived while the cutoff was set as two or more consecutive sample DNA≥15pg/?l in a week,and the sensitivity and specificity was 94.4% and 100.0%,respectively.CONCLUSIONS Real-time fluorescent quantitative PCR is helpful in early diagnosis of invasive aspergillosis.

AIM To evaluate the prevention and treatment of N-(2-mercaptopropionyl)-glycine sodium (MPG-Na) and tiopronin (MPG) on acute liver injury. METHODS The experimental mouse model of hepatotoxicity induced by D-galactosamine (Gal) was applied to investigate preventive and remedial effects. In the preventive experiment, the mice were ip administered with MPG-Na or MPG 37.5，75 and 150 mg·kg~(-1), respectively, for 7 d. Gal 800 mg·kg~(-1) was ip given into the mice 30 min after the last administration. In the remedial experiment, the mice were ip given Gal 800 mg·kg~(-1) and 30 min later followed by MPG-Na or MPG 37.5, 75 and 150 mg·kg~(-1) , respectively, for 2 d. The mice were euthanized and serum was prepared 24 h (pre-treatment) or 48 h (post-treatment) after Gal injection. The activities of serum glutamyl pyruvic transaminase (GPT) and glutamyl oxaloacetic transaminase (GOT), the contents of total protein (TP) and albumin (Alb), and the Alb/globulin (A/G) ratio were determined. The liver tissues were collected for histopathological assessment (HE staining) under light microscope. RESULTS Compared with normal control group, the activities of serum GPT and GOT in model group were significantly increased. The injuries such as fatty degeneration and liver cell necrosis were observed. Compared with model group, the activities of GPT and GOT in pre-treatment groups were obviously decreased in MPG-Na 150 mg·kg~(-1) group. In post-treatment groups, the activity of GPT decreased in 3 MPG-Na groups. The contents of TP, Alb and A/G ratio had little change. In addition, MPG-Na alleviated the injuries such as fatty degeneration and liver cell necrosis obviously. Compared with MPG, MPG-Na showed similar effect. CONCLUSION MPG-Na has an obvious protective effect against Gal-induced acute liver injury in mice and the efficiency is equivalent as MPG.

Objective : o evaluate the association between Crohn's disease (CD) and frailty using a Mendelian randomization (MR) approach, so as to provide the evidence for prevention and control strategies. Methods: Genetic association data for CD were collected through the International Inflammatory Bowel Disease Genetics Consortium, with 20 883 samples and 12 276 506 single nucleotide polymorphism (SNP), and genetic association data for frailty were collected through a meta-analysis including 175 226 samples and 7 589 717 SNPs. A forward MR analysis was performed using the inverse-variance weighted (IVW) method with 37 CD-associated SNPs as instrumental variables, and frailty as the study outcome, and a reverse MR analysis was performed with 13 frailty-associated SNPs as instrumental variables and CD as the study outcome. The heterogeneity was assessed using the Cochran's Q test, and the horizontal pleiotropy was assessed using the MR-PRESSO global test and MR-Egger regression. In addition, the robustness of the results was verified with the leave-one-out. Results: Forward MR analysis results showed that patients with genetically predicted CD had an increased risk of frailty index relative to those without CD (β=0.018, 95%CI: 0.011-0.026, P<0.05). Cochran's Q test detected no heterogeneity (P>0.05), and neither the MR-PRESSO test nor the MR-Egger regression revealed horizontal pleiotropy of instrumental variables (both P>0.05). Leave-one-out analysis showed robustness of the MR analysis results. Reverse MR analysis showed no association between frailty index and the risk of CD (OR=0.740, 95%CI: 0.206-2.661, P>0.05). Conclusions Genetically predicted CD is associated with an increased risk of frailty. It is suggested that screening and prevention of frailty should be reinforced among CD patients.

Objective To assess the efficacy and safety of recombinant human granulocyte colony stimulating factor (rhG-CSF) primed donor peripheral blood stem cell (PBSC) on the treatment of poor graft function (PGF) after allogeneic stem cell transplantation(allo-HSCT).Methods The patients diagnosed as PGF after allo-HSCT and transfused with rhG-CSF primed PBSC from January 2003 to November 2012 were retrospectively analyzed.Hematological response was assessed at day 30 after transfusion.Graft versus host disease (GVHD) was assessed until 6 months after transfusion.Results There were 28 patients including 21 men and 7 women with a median age of 28 (12-50) years old.Of these patients,16 were diagnosed as primary PGF.The median number of transfused mononuclear cells was 2.0 (1.0-5.8) ×108/kg.Totally 42.9％ (12/28) patients achieved good response.Eight patients (28.6％) developed GVHD.Sixteen patients (57.1％) survived.Age (≤/＞ 28 years),gender,donor type (matched sibling/mismatched related),additional conditioning regimen prior to transfusion,time of neutrophil engraftment (≤/＞ 18 days) time of transfusion (≤/＞ 100 days after allo-HSCT) and number of mononuclear cells (≤/＞ 2.0 × 108/kg) did not impact hematological response.However,response rate of primary PGF (4/16) was significantly lower than that of secondary PGF (8/12) (P =0.022).Conclusion Transfusion of PBSC mobilized by rhG-CSF could be considered as an option to treat secondary PGF after allogeneic stem cell transplantation.

Clinical characteristics were analyzed retrospectively in a patient with empty sella and adrenal adenoma with regard to the elaborated diagnosis and treatment.Although empty sella syndrome alone was common,clinical combination with adrenal adenoma was rarely reported.It was difficult to diagnose due to complex symptoms and hormone levels.This case could help increase awareness of the disease and accumulate the experience in diagnosis and treatment.
