The effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the arachidonic acid(AA) metabolism were examined by incubating separately washed human platelets and human umbilical artery rings with labelled AA. The results are as follows:1.Both EPA and DHA reduced the formations of TXB2 in platelets and 6-keto-PGF1a in artery walls in dose-dependent way.2.The effect of EPA on the synthesis of HETE by platelets was different with the concentrations of EPA. At lower concentration (62.5?M), it increased the formation of HETE, but the degree of increase was lowerd when the concentration of EPA was increased further, and even reduced the formation of HETE when its concentration reached 1000?M although the decrease extent was statistically insignificant.3.At all of concentrations used but 62.5?M, DHA raised potently the formation of HETE by platelets in dose-dependent way.A brief discussion was made about our results with special references to former data reported.

[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.

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 prepare rufloxacin hydrochloride gel and establish a quality control method of the gel METHODS:Carbopol940 was used as the gel base,the content of rufloxacin hydrochloride was determined with UV-spectrophotometry and the stability test was performed RESULTS:There was a good linearity of calibration curve of rufloxacin hydrochloride in range 2～10?g/ml,r=0 9 999,the average recovery was 99 53%,RSD was 0 38%(n=6) The gel was stable CONCLUSION:The design of the gel formulation is reasonable The gel can be prepared feasibly and is stable in quality,convenient in use

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.

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.

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.
