Pharmacometabonomics, as an emerging branch of system biology, has been increasingly used in personalized medicine and showed broad prospects. By means of metabonomics, the complicated and detailed metabolic profile of the patient is described, thus providing more detailed description of the disease phenotype. With this understanding, response of different individuals to the drugs are predicted or evaluated through inherent genetic information of the individual combined with the environmental factors. As a result, appropriate drugs and dosage are chosen, which greatly promotes the realization of the individualized therapy goals. This article describes the emerging field of pharmacometabonomics, and the research results of personalized medicine based on the pharmacometabonomics in recent years are reviewed in detail.

Objective To investigate the expression and clinical significance of serum ferritin in patients with lung cancer. Methods The relationship between preoperative serum ferritin level and corre-sponding clinicopathological data in 174 patients with lung cancer and 85 patients with benign pulmonary diseases was reviewed and analyzed. Results The level of serum ferritin in patients with lung cancer was significantly higher than that in patients with benign pulmonary diseases. For non-small cell lung cancer, patients with large-sized,poorly differentiated squamous carcinoma in advanced stage had higher serum ferritin levels than those with small-sized,highly or moderately differentiated adenocarcinoma in early stage. Conclusion Serum ferritin may play a promoting role in the development and malignant progres-sion of lung cancer.

ObjectiveTo investigate the relation between each subtype of cerebral ischemic stroke classified by NEW-TOAST criteria and the levels of blood sugar. MethodsA retrospective study in 624 patients hospitalized with acute cerebral ischemic stroke. All the patients were classified using NEW-TOAST classification standard. Blood glucose in patients with different stroke subtypes was recorded, and analyzed for the incidence of abnormal glucose metabolism in each subtype. The correlation of glucose to blood sugar,blood pressure and blood fat was analyzed using odd ratio (OR) and 95% confidence intervals (CI).Results(1) Among 624 patients, the most common stroke subtype by NEW-TOAST classificationis atherothrombosis (AT), followed by small arterial occlusion (SAO). One hundred and nineteen patients (19. 1% ) had diabetes history; another 40 patients(7.5% ) were newly diagnosed with diabetes in this study; and 71 patients ( 11.4% ) were found to have glycoregulation abnormality. The incidence of abnormal glycometabolism was high in patients with AT ( 40. 4% ) and SAO ( 39. 7% ). ( 2 ) Association analysis between stroke subtypes and blood sugar: x2 =14. 83,P =0. 020, r =0. 152; in SAO patients, OR was 1. 925 (95% CI 1. 392-2. 664) ; in the patients with AT, there was no correlation to blood sugar levels.Association analysis of high blood pressure in stroke subtypes: in AT patients, OR was 2. 874 (95% CI 1. 957-4. 222) ; in SAO, OR was 1. 609 (95% CI 1. 100-1. 235). Association analysis of high LDL-C in each subtype: OR in SAO was 1.419 (95% CI 1.026-1. 962) ;No significant correlation of LDL-C in AT patients, P =0. 929 ; (3) There is significant difference of frequency of abnormal glycometabolism between stroke subtypes: x2 =17. 79 ,P =0. 000; between AT and SAO patients, x2 =0. 024,P =0. 877; between AT or SAO patients to other three subtypes, P < 0. 05. ConclusionsAmong the subtypes of cerebral ischemic stroke by NEW-TOAST classification, AT and SAO are the most common subtypes.All the subtypes have correlation to the high level of blood sugar, and SAO has the highest correlation to blood sugar levels. High blood pressure may affect both large vessels and small vessels, while high LDL-C may mainly affect small vessels.

Objective To prepare and identify the monoclonal antibody (mAb) specific to epithelial cell adhesion molecule (EpCAM) and explore the function of the mAb.Methods The EpCAM antigen expressed by the prokaryotic expression systems was used to immunize the BALB/c mice,and then the splenic cells from the mice were fused with the Sp2/0 cells to produce hybridomas secreting specific mAb.The positive clones were screened by the ELISA.The western blot analysis was used to identify the reactivity of the mAb to the antigen.Then the immunohistochemistry staining was used to detect EpCAM expression in the 3 primary colorectal carcinoma tissues.Results Three mAb specific to EpCAM were obtained by ELISA tests.Western blot results indicated that these three kinds of antibodies could react to the EpCAM antigen,but no response to the GST tag.Immunohistochemical staining results identified that these mAb could give positive signals to the primary colorectal carcinoma tissues from patients.Conclusion Three mAb specific to EpCAM are obtained and identified,which contributes to the diagnosis and therapy of the carcinoma in the future.

Human neutrophils defensins, e.g., human neutrophils peptides (HNP), had been found in polymorphonuclear neutrophil and shown broad antimicrobial activity, cytotoxicity and chemotaxis as an important family of human innate defence components. The researches on defensins is becoming a worldwide major focus of biological and medical attention nowadays. The researches on molecular characteristics, biological and pathophysiological activities of HNP are reviewed.

Objective To design a quantitative criterion and grading system for injury from adverse drug reaction (ADR) in order to serve the compensation system of injury from ADR. Methods Based on the other grading system of injury cases, the independent scores and serial grades were given to the ADR injury of different organs or different levels through two turns of consultation to 27 experts from Shanghai. Results Injury from ADR was graded from stage 1 to stage 10 according to the damage degree, with 1 stand for death and 10 for slightest injury. Conclusion The grading method of ADR based on the characteristics of injury accords with the condition of China, and can provide reference for making up the compensation system of ADR injury.
