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.

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.

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.

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.

PKHD1 ( polycystic kidney and hepatic disease 1), the causal gene of human autosomal recessive polycystic kidney disease(ARPKD), is located on chromosome 6p12.2 and covers a genomic region of ～500 kb. PKHD1 is among the largest human genes, with a minimum of 86 exons from which multiple transcripts may be generated by alternative splicing. The longest continuous open reading frame consists of 12 222 bp, encoding a 4 074 amino acid protein, designated as fibrocystin/polyductin (FPC). FPC is predicted to be a receptor like protein, with single transmembrane domain and a short cytoplasmic tail. The expression of mouse FPC can be detected in various duct-containing organs. In mouse embryogenesis, FPC appears in developing neural tube, bronchi, and the primordial gut as early as the day of E9.5. In fetal human kidneys, high level of FPC expression is present in ureteric bud and its expression continues throughout the process of renal tubuobranching. In adult human kidneys, FPC mainly expresses in the epithelia of renal collecting ducts. FPC is subcellularly localized to the primary cilia and concentrated on the basal bodies in renal epithelial cells. The detail function of FPC is still unrevealed, most recent studies demonstrate that FPC, as a receptor, may transduce cell signal by interacting with a trp superfamily TRPP2 (PKD2), which is a causal gene for ADPKD, and mediate intracellular calcium homeostasis to regulate differentiation, proliferation, migration and polarity of various duct/tubular epithelia, in turn, to modulate the formation of all physiologic ducts, tubules and tracts.

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.

Objective:To understand the situation of drug expense dishonour to the patients participated in health insurance new rural cooperative medical system ( NCMS) in our hospital, analyze the dishonour reasons and find countermeasures. Methods:The da-ta of drug expense dishonour to the patients participated in health insurance NCMS were collected in our hospital during October 2014 and October 2015, the reasons for the dishonour were analyzed, and countermeasures were proposed in order to reduce the dishonour under the policy of health insurance NCMS. Results:The most common reason of drug expense dishonour was the violation of restricted medication rules in the policy followed by the irrational use of Chinese medicines and antimicrobial drugs. Hospital should look for countermeasures according to the reasons for the dishonour in order to promote the implementation of the new rural cooperative medical policy and strengthen the rational and regular drug use under the policy of health insurance NCMS. Conclusion: The most important reason for drug expense dishonour was the incompletely implementation of the policy of health insurance NCMS, and the violation of drug use exists in our hospital. Pharmacy department should supervise drug use, focus on promoting the policy of health insurance NC-MS, implement forward position, participate in medication development and promote rational drug use.

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.
