Objective To investigate the clinical characteristics of methylmalonic acidemia.Methods Methylmalonic acidemia diagnosis and treatment of 12 cases of clinical data were collected,the clinical manifestations,laboratory examinations,gas chromatography/tandem mass spectrometry analysis of the measurement results of urine organic acids,blood gas analysis,glucose,lactic acid,ammonia and other characteristics were sumarized,and the clinical features and outcome of the situation were also sumarized.Results 1 year old first visit eight cases,12 cases,8 cases from rural areas;12 cases of major treatment complained of anorexia,poor spirit hospitalized one case;respiratory infection hospitalized five cases; seizure hospitalized three cases;weight gain admission,one case;vomiting admitted three cases,three cases of drowsiness,coma admitted one case,the movement behind the main complaint admitted two cases.After hospitalization check urine organic acid analysis found significantly increased methylmalonic acid,respectively,while ammonia,lactic acid increased,high blood sugar,high uric acid,low albumin,urine protein abnormalities,abnormal urine ketone bodies,abnormal increased anion gap,video science and abnormal electrophysiological examination.Diagnosed with methylmalonic acidemia,according to the case were given VitB12,betaine,folic acid,L-carnitine,limiting protein intake and other treatment.Symptomatic treatment improved in seven patients,two patients were lost;automatically discharged one case,two cases of death.Conclusion Methylmalonic acidemia based on clinical characteristics,so early detection,early diagnosis,early treatment will help to improve prognosis.

The injury of vascular endothelium,activation of coagulation and exist of fibrinolysis in patients with acute leukemia caused the coagulation disorders.It would appear hypercoagulation status or thrombosis,and the incidence was about 10 ％- 40 ％.It appeared in the early phase of this disease,chemotherapy or infection,and may have no clinical symptoms or signs.The routine coagulation index was also very difficult to detect this hyper coagulation state.Therefore,monitoring in different phrase the content of plasma AT-Ⅲ,vWF and DD in acute leukemia provided the evidence for early diagnosis,prevention and cure of acute leukemia.

Diffuse large B-cell lymphoma(DLBCL),the largest category of lymphoma,is a clinically and biologically heterogeneous disease entity.Immunophenotype,tissue microarray and molecular studies underline the extreme heterogeneity of DLBCL and suggest a subclassification of the tumor.This review summarizes the morphological,immunophenotypic,cytogenetic and molecular genetic features of DLBCL relevant to the precise prognostic previsions.

Eph,the largest subfamily of tyrosine kinase receptor, could be divided into two groups,EphA and EphB.Ephs play a role in the embryonic development and differentiation of the nervous and vascular systems. In recent years,a large number of ephrins and Ephs had been found to be overexpressed in numerous human tumors,and have relation to development and prognosis of cancers.Down-regulated of EphA3 and EphA7 in cancers,was attributed to the hypermethylaiton of CpG island in promoter region.

Objective:Ephs have been found to be over-expressed in numerous human tumors,and relate to the development and prognosis of cancers.The expression of EphA7 in colon cancer cell lines and primary colorectal cancers was detected.The role of EphA7 in the development of colorectal cancer was investigated. Methods:Quantitative reverse transcription-polymerase chain reaction was used to detect the expression of EphA7.Methylation specific PCR and bisulfite sequencing were used to examine the methylation status of EphA7.pEGFP-EphA7 plasmid was constructed and was transfected into HCT116 which lost the expression of EphA7.Gene chip was analyzed for the expression of genes between transfectant and mock cell. Results:Down-regulation of EphA7 was observed in cell lines of primary colorectal cancers,and the evidence of aberrant methylation was found in CpG island of EphA7 promoter.The methylation status of EphA7 gene was related to sex,differentiation and location of colorectal cancers.Some genes were up or down regulated in pEGFP-EphA7 transfectant. Conclusion: EphA7 gene may be involved in the carcinogenesis of colorectal cancer.The hypermethylation of CpG island is an important mechanism leading to the down regulation of EphA7 in colorectal cancer.

This review summarized the biological activities of natural saponins,introduced its action mechanisms,clinical applications and research progresses in cardiovascular system,antitumor,immunological enhancement,blood sugar suppression,contraception,antifugal and insecticide,etc,and prospected its exploitations.

OBJECTIVE:To improve the medication compliance of diabetic patients.METHODS:A questionnaire survey was conducted on the spot with Excel used for data input,and the data were analyzed statistically using chi-square test in SPSS13.0 software.RESULTS & CONCLUSION:The medication compliance rate of the 193 diabetic patients was low at 47.15%.The diabtes patients' medication compliance can be improved through regular consultation,recognition of disease,knowledge on drugs and better pharmaceutical care.

Medical electron linear accelerator and Gamma-ray stereotactic radiotherapy system,two kinds of large scale medical equipment,both have an medical treatment on patient by imposing a high-level of radiation.The accuracy of deferent dose and validity of therapy programe play a very important role to patients'security and treatment effect.Both the military and local governments Pay a lot of attention to the two kinds'allocation and quality control.As technical administrative department.the Medical Equipment Application Quality Test and Research Center of PLA analyse current situation of the two kinds detailedly and point out the existing problems based on quality of the two kinds of equipment used in military medical agencys.

Since the implementation of the Trial Measures of Degrees in Clinical Medicine in 1998,the application for clinical M.D.degree for in-service doctors has been considered as way of continued education for medical practitioners.To guarantee the quality of this education mode,Peking University Health Science Center adopted measures and achieved outcomes that are parallel to that of full-time M.D.programs.-service doctors at,This paper introduces the experience of PUHSC and proposes measures for MD program of in-service doctors in terms of quality control,informatization,etc..

Berberine is a taste of traditional Chinese medicine.With the progress of research on pharmacology and mechanism of drug action of extensive research,the new mechanism of berberine was revealed through a series of clinical trials,the clinical indications continue to expand,and berberine has a therapeutic effect in digestive and endocrine system disease.The current study confirmed that berberine not only has the broad-spectrum antibacterial activity,but also plays a strong anti-inflammatory and immune regulatory role,which makes more and more research began to concern its application value in the diseases of respiratory system.The strong anti-inflammatory effect of berberine cau effectively relieve the airway inflammation of patients who are suffering from chronic obstructive pulmonary,and the broad-spectrum antibacterial effect brought hope for the treatment of tuberculosis and pneumonia.The subsequent animal and clinical studies have confirmed that berberine can effectively improve the symptoms of respiratory system diseases,and play a role in the treatment.
