Objective To explore the diagnostic value of serum myoglobin (Mb) and cardiac troponin (cTn) in patients with acute myocardial infarction (AMI) by reviewing and evaluating the corresponding references with evidence-based medicine (EBM) theory.Methods All references (including papers,reviews and abstracts) of CNKI-CHKD,CMCC(1994-2005)and EMCC(1995-2005) were collected and retrospectively analyzed according to evidence based medicine (EBM) standard,with Mb cTn as the detected indices for diagnosing AMI.Results In the searched period of 1994-2005,123 papers were published (93 pieces were written in Chinese,and 30 were written in English). In most references,the authors set clinical control trial (CCT) (Chinese: 92.5%;English: 53.3%),blind control trial (Chinese: 19.4%;English: 10.0%) and/or random control trial (RCT) (Chinese: 9.7%;English: 16.7%). The respective reference ranges weren′t provided in 42 pieces of articles.Conclusion The analytic result of the references in home and aborad indicates combined detection of Mb and cTnI posseses favourite sensitivity and specificity,which contributes to the early diagnosis of acute myocardial infarction.

Objective　To study on effects of mVEGF and anti-VEGF antibody during cultured HUVEC proliferation in vitro.Methods　Endothelial cell proliferation was assayed using human umbilical vein endothelial cells stimulated with mVEGF and with CIA joint extracts and was used　　3　　H-TaR incorporation.Results　The anti-VEGF neutralizing antibody can inhibit the proliferation of HUVEC stimulated with mVEGF and with CIA joint extracts,whose suppression percents were 72.2% and 69.9%,respectively.Conclusion　mVEGF specifically promotes the growth of vascular endothelial cells.During early stage of CIA development,expression of VEGF in the joint increases and VEGF is expressed biologically active and can be inhibited by anti-VEGF neutralizing antibody.

Objective To assess the effect of 5-azacytidine (5-AZ) on the expressions of atrial natriuretic peptide (ANP) and β-myosin heavy chain (β-MHC) genes in cultured rat bone marrow stromal cells (BMSCs). Methods Neonatal rat cardiomyocytes and adult rat BMSCs were isolated and cultured. BMSCs were incubated with 5-AZ and (or) myocardiocytes culture medium. RT-PCR was used to measure the expressions of cardiac ANP and β-MHC genes. Results Normally cultured rat BMSCs didn't express cardiac ANP or β-MHC. After inducing by 5-AZ, rat BMSCs expressed ANP or β-MHC. The myocardiocytes culture medium enhanced expression of β-MHC, but didn't affect the expression of ANP. Conclusions The 5-AZ induces the rat BMSCs to express either cardiac ANP or β-MHC, and the former could be enhanced by cardiomyocytes culture medium.

The velocity of blood in vessels is an important indicator that reflects the microcirculatory status. The core of the measurement technology, which is based on spatiotemporal (ST) image, is to map the cell motion trace to the two-dimensional ST image, and transfer the measurement of flow velocity to the detection of trace orientation in ST image. This paper proposes a trace orientation measurement algorithm is based on Randomized Hough Transformation and projection transformation, and it is able to estimate trace orientation and flow velocity in noisy ST images. Experiments showed that the agreement between the results by manual and by the proposed algorithm reached over 90%.

Metoclopramide ( MCP ) is similar to Procainamide in structure. In rats anaesthetized by ip chloral hydrate 300 mg/kg, arrhythmia induced by BaCl 3 mg/kg was shown to be antagonized by injecting iv MCP 30 mg/kg. It was also found that MCP 10 mg/kg injected iv protected rabbits against a'rrhythmia induced by chloroform-adrenaline . In anaesthetized rats, MCP 30 mg/kg injected iv raised the dose of aconitine required to induce first arrhythmia, ventricular fibrillation ( VF ) and heart arrest, while in anaesthetized guinea pigs, the same amount of MCP injected iv showed no significant action on the dose of ouabain inducing these effects. Ventricular tachycardia produced by occlusion of coronary artery in rats could not be prevnted by injecting iv MCP 30 mg/kg. It was found that MCP has local anaesthesia action.

Objective To improve the diagnosis and treatment of hepatolithiasis associated with cholangio-caminoma.Methods Data of 28 cases of hepatolithiasis associated with intrahepatic cholangiocarcinoma from 2005 to 2008 in Li Huili Hospital of Ningbo University Medical School were collected and analysed.Results The diagnosis was established preoperatively in 8(28.6%)cases.Twenty-one(75.0%)patients were radically resected,5(17.9%)patients received palliative operation,and other 2(7.1%)patients received exploratory surgery.In the 24 patients followed-up closely,the median survival time was 30 months in radical surgery group,8 months in palliative operation group,whereas 2 exploratory surgery cases only survived 2 months and 4 months respectively.Conclusions Cholangiocarcinoma may be related to hepatolithiasis.Early diagnosis rate is low and prognosis is poor in the cholangiocarcinoma associated with hepatolithiasis.Early radical therapy for hepatolithiasis plays an important role in preventing cholangiocarcinoma occurrence.Palliative operation for cholangiocarcinoma may improve quality of live.

Objective]Discussesing Professor Lu Su's experience for the treatment of gynecologic tumor bone marrow suppression after chemotherapy. [Methods] Through learning from the teacher, collecting and collating the relevant information and medical records ,summarizing the doctor's treatments for bone marrow suppression,introducing the special treatment from nourishing Yin and Yang, dialectical analysis;combination of Chinese and western, foster strengths and circumvent weaknesses;treatment based on overall, overall consideration;Regulate mood,treat both heart and kidney at the same time,and give examples to prove it. [Results] Professor Lu Su believes that the disease in the Yin and Yang as the main pathogenesis of the disease, the treatment nourishing of Yin and Yang, clinical examination of the combination of the dialectical analysis,nourishing Yin and Yang, dialectical analysis, for the treatment of gynecologic tumor bone marrow suppression after chemotherapy, with a certain clinical significance. [Conclusion ]Professor Lu Su's unique method of treatment of gynecologic tumor bone marrow suppression after chemotherapy, has remarkable curative effect.Her treatment and academic thoughts of bone marrow suppression of gynecological tumor after chemotherapy open a new path, unique method, and the effect is significant, the syndrome differentiation typing, prescription and addition and subtraction cut to clinical treatment after chemotherapy myelosuppression is of practical value, it is worth learning.

Heterotopic ossification is the abnormal formation of true bone within extraskeletal soft tissues, which frequently showing a predilection instead for fascia, tendons, and other mesenchymal soft tissues. This paper summarized differential types and quantities of regulatory proteins expression at different stages of heterotopic ossification by proteomics techniques, and screened differential expression of functional proteins at different time points. Further more, identificated and validated certain proteins, which helpful to discovery new regulatory proteins and explore the mutual relationships among the proteins. Proteomics has extensive applications in regulatory proteins research of post-traumatic heterotopic ossification, can further elucidate the mechanism of post-traumatic ectopic bone formation and search for new regulatory biomolecule regulatory sites.
