Objective　To observe the effect of nordihydroguaiaretic acid treatment combined with Methotrexate or Vincristine on a human malignant glioma cell line. Methods　The effect of drugs on the cells was measured by MTT, and the protein expression of cyclin D1 gene in the cells was measured by immunohistochemistry assay. Results　①The anti-tumor effects of drugs on the cells were increased with the increasing of concentrations, and had a combined function between NDGA and MTX or VCR. ②There was no difference between the effect of treating NDGA with MTX or VCR given at the same time and MTX or VCR given after 24 h of NDGA treatment, but the effects were apparently different when NDGA was administrated after MTX or VCR treatment for 24 h. ③The protein expression of cyclin D1 gene in the cells was apparently reduced after NDGA treatment. Conclusion　There is a cooperative function between NDGA and MTX or VCR on the cells, and the function is probably related to the NDGA-induced down-regulation of protein expression of cyclin D1 gene in the cells.

Cytochrome P450 enzyme are an important enzyme family in drug metabolism. Human cytochrome P450 enzymes have been studied entensively about their polymorphism in recent years. polymorphism of CYP2C19 and CYP2D6 have been detected at both phenotypic and genotypic level, and their molecular mechanism have been studied entensively, however, the molecular mechanism of other enzymes for exzample CYP2C9,CYP1A1,CYP2E1 et al) is being discussed, though these enzymes possiblely exist polymorphism. The article summarizes the substrates of P450, molucular mechanism of polymorphism, and paticular reference to the effects of this variation on drug metabolism and susceptibility to chemically-induced diseases.

Diastolic and systolic dysfunction of cerebral artery is an important pathophysioiogical basis of the occurrence and development of cerebrovascular diseases, and is also the presence of decreased cerebrovascular reserve capacity. Cerebrovascular myogenic and metabolic regulation abilities can be evaluated by different methods so as to reflect cerebrovascular reserve capacity, of those, transcranial Doppler ultrasonography is the most widely used one. Various diseases, such as hypertension, diabetes mellitus, and carotid atherosclerosis also have great effect on cerebrovascular reserve capacity.

[Objective] To emphasize the importance of early prevention and treatment, this article discusses on the theory and application of preventive treatment of disease from traditional Chinese medicine in prevention and treatment of carotid atherosclerosis in patients with diabetes. [Methods] With de-tailed research into related study of risk factors affecting carotid atherosclerosis in type 2 diabetic patients from recent years, comprehensive summary of tra-ditional risk factors and risk factors of the latest findings were demonstrated. The prevention and treatment of carotid atherosclerosis in type 2 diabetes mel itus was discussed in two aspects by theory of“preventive treatment of disease. [Result] In diabetic patients without carotid atherosclerosis, early and timely intervention can prevent the occurrence and development of the diabetes vascular lesions; In diabetic patients with carotid atherosclerosis, active treatment can reduce the incidence of stroke, myocardial infarction and other critical care. [Conclusion] In patients with type 2 diabetes, risk factors affect-ing carotid atherosclerosis should be control ed and intervened early, which can effectively reduce the occurrence and development of the diabetes vascular lesions to improve the quality of life, but early diagnosis technology and indicators need to be further researched.

Cancer is one of the gene diseases. The genome stability is closely associated with the occurrence of cancers. XRCC1 gene is one of the DNA repair genes. It participates in the repair process when the genome is injured. So it is considered important in maintaining the stability of the genome and in the prevention of tumor occurrence. This article introduced the characteristic of XRCC1 gene, the relationship between single nucleotide polymorphism of the gene and susceptibility to tumor, and the common methods used in the XRCC1 research.

Objective To observe the correlation between protein C activity-dependent clotting time-normalized ratio (PCAT-NR) and the related blood coagulation parameters,e.g.,fibrinogen (Fib),factor Ⅶ coagulant activity (Ⅶ:C),factor Ⅷcoagulant activity (F Ⅷ:C),antithrombin (AT),D-dimer (DD) in patients with acute cerebral infarction.Methods One hundred cases of patients who were diagnosed as acute cerebral infarction according to clinical manifestations and imaging examinations were taken as the test group and 75 healthy subjects were taken as control group.The values of Fib,FⅦ:C,FⅧ:C,AT,PCAT-NR,DD were tested and the difference between the two groups were compared.The differences of Fib,FⅦ:C,FⅧ:C,DD and AT between declined PCAT-NR group and normal PCAT-NR group in the patients with acute cerebral infarction were analyzed.The correlations of PCAT-NR with other coagulation parameters in acute cerebral infarction cases were compared.Results The values of Fib (3.38 ± 1.25) g/L,F Ⅶ:C (130.5 ± 15.9) ％,FⅧ:C (135.8 ± 43.1) ％ and DD (2.12:±:3.01) mg/L in the acute cerebral infarction group were significantly higher than those of control group,while the values of AT (83.94 ± 14.95) ％ and PCAT-NR (0.87 ± 0.23) in test group were significantly lower than those the control group (P＜0.05).The values of Fib (4.03 ± 1.25)g/L,FⅦ:C (138.2 ±6.9)％ and FⅧ:C (151.5 ± 54.9)％ of PCAT-NR declined group in the patients with acute cerebral infarction were significantly higher than those of PCAT-NR normal group (P ＜ 0.05),while the values of DD,AT were not statistically different between two groups (P ＞ 0.05).The values of PCAT-NR were significantly negatively correlated with Fib,FⅧ:C and DD in the patients with acute cerebral infarction (r =-0.484,-0.356 and-0.473,respectively (all P ＜ 0.05).There was no correlation of PCAT-NR with FⅦ:C and AT (P ＞ 0.05).Conclusion The PCAT-NR decline was associated with high coagulation state in patients with acute cerebral infarction.This decline has some correlation with high level of blood clotting factor Ⅷ and Fib.

Objective To analyze the clinical effects of dexmedetomidine on postoperative agitation in children patients . Method Forty-four children undergoing surgeries in our hospital between March 2011 and March 2014 were treated with intravenous injection of 10 mL dexmedetomidine with a dose of 0.5μg/kg in 15 minutes after general anesthesia. Result The occurrence rate of postoperative restlessness was only 6.82%(3/44). Conclusion The use of dexmedetomidine combined with specific clinical nursing intervention for children undergoing surgery can effectively reduce the occurrence of postoperative restlessness , which ensures the clinical therapeutic effect and life safety.

Early diagnosis of inflammation and properly interfere to improve the prognosis are very important.However,it is difficult to verify inflammation or differentiate inflammation from infection in clinic,especially in the condition of underlying inflammation.Currently,radiopharmaceuticals based on researches of pathophysiology progress of diseases are studied constantly.This review summarizes the potential inflammation imaging radiotracers and their mechanisms,potential clinical application value.
