BACKGROUND: Dynamic balance of endothelin (ET) and calcitonin gene-related peptide (CGRP) plays an important role in occurrence and development of cerebral infarction.OBJECTIVE: To observe the effects of thromboiytic therapy with batroxobin(DF-521) on the levels of plasma ET and CGRP after cerebral infarction.DESIGN: Randomized controlled study.SETTING: Fourth Department of Gereology, General Hospital of Guangzhou Military Area Command of Chinese PLA.MATERIALS: The experiment was performed at the Fourth Department of Gereology, General Hospital of Guangzhou Military Area Command of Chinese PLA. Totally 15 New Zealand rabbits aged from 18-20 months, of common grade and either sex, with the mean body mass of (3.5±0.5) kg were selected.METHODS: A total of 15 rabbits were established into cerebral infarction models with modified autogeneic thrombus method. One rat died when selecting models. Other 14 rats were randomly assigned into control group and treatment group. DF-521 was slowly injected into vein of ear edge of rats in the treatment group at hour 2 after embolism. Saline of the same volume was slowly injected into rats of the control group. Changes of concentrations of plasma ET and CGRP in the treatment group and control group were observed before and after cerebral infarction.MAIN OUTCOME MEASURES: Changes of ET and CGRP contents 1 hour before operation, 2 hours after operation (before drug injection) and 6 hours after operation (4 hours after drug injection).RESULTS: Of the 15 included rabbits, 1 rat died when establishing model, so 14 rabbits were involved in the result analysis. ET level significantly increased at hour 2 after acute cerebral infarction operation in the treatment group and control group (P ＜ 0.05, P ＜ 0.01), and then decreased at hour 6 after operation (P ＜ 0.01 ,P ＜ 0.01 ). The decrease in the treatment group was larger than that in the control group (P ＜ 0.01 ). The level of CGRP markedly reduced at hour 2 after acute cerebral infarction operation in the two groups, and than increased at hour 6 after operation. The increase in the treatment group was larger than that in the control group, but there was no statistical difference (P ＞ 0.05).CONCLUSION: Body with cerebral infarction during acute stage has selfregulative mechanism on dysequilibrium of ET and CGRP. Early-used thrombolytic therapy with DF-521 can markedly increase the ET level,which may be one of the protective mechanisms of cerebral ischemical reperfusion injury.

Objective To study the expression level of PKM1 and PKM2 in colorectal cancer tissue and explore the relationship between colorectal cancer progression and their expression level.Methods The PKM1 and PKM2 protein expression levels in colorectal cancer tissues and adjacent tissues to carcinoma were determined by Western blot and Immunohistochemisty method, and the relationship with colorectal cancer were discussed. Results Western blot and Immunohistochemisty results all showed that, compared with adjacent noncancerous, the protein level of PKM1 decreases significantly in cancer tissues (P<0.05), while the protein level of PKM2 increases significantly in cancer tissues (P<0.05).The protein level of PKM1 is not relative with age,sex and stage of patients, but the protein level of PKM2 is relative with pTNM(P<0.05).Conclusion Colorectal cancer tissues with low level of PKM1 and high level of PKM2, and PKM2 was related with TNM of patients.

OBJECTIVE:To explore the role of clinical pharmacists participating in anti-infective treatment for a child with complex infection. METHODS:Clinical pharmacists participated in treatment process of one child with pulmonary infection and brain abscess after a near-drowning incident,assisted physicians to adjust antibiotics therapy plan,and put several suggestions as the adjustment of anti-gram-positive and anti-gram-negtive bacterium drugs,the dosage adjustment of vancomycin,vancomycin-induced ADR and disposal,the selection of anti-Pasteurella pneumotropica drugs,the enhancement of anti-fungal infection therapy,accord-ing to pathogen characteristics,treatment effect and ADR. RESULTS:Physicians partly adopted the advice of clinical pharmacists, the child’s pulmonary and brain infection were controlled effectively and ADR disappeared after 5 times of adjusting anti-infective the rapy plan. CONCLUSIONS:Clinical pharmacists participate in the treatment process of one child with complex infection,and assist physicians to formulate safe and effective anti-infective plan according to the results of etiological examination;dispose ADR timely and carry out efficacy evaluation of antibiotics and pharmaceutical care,that can give positive effects on patient treatment.
