Telomerase can inhibit the shortening of telomere and stimulate continuous cell proliferation to form tumor.The activity of telomerase can be prohibited by G-quadruplex formed by the single chain in G-rich field of telomere 3' end, resulting in tumor cell apoptosis.Ligands which can induce the formation or stabilize the structure of G-quadruplex in G-rich field of oncogene exhibit antitumor function. Nowadays it becomes the core concern of chemists and biologists to screen and structurally design the compounds targeting G-quadruplex.This paper summarized the discoveries in the G-quadruplex-targeted telomerase inhibitors in recent years.

Objective To investigate the treatment function and dominance of Ommaya reservoir,which was used to treat postoperative intracranial infection combined with hydrocephalus in patients with severe traumatic brain injury. Methods Thirty-four patients suffered intracranial infection combined with hydrocephalus after operations. They were randondy divided into 2 groups.Thirleen patients were treated with Ommaya reservoir, the others were treated with external ventricular drainage. The 24-hour mean drain quantum, the mean days from implantation pumps or htbes to ventriculo-peritoneal (V-P) shunt operation,the rate of secondary operation and the rate of getting V-P shunt operation were analyzed, then the Glasgow outcome scale ( GOS ) of patients were observed at 3 months. Results Compared with patients treated with external ventriular drainage, patients with Ommaya reservoir had the less24-hour mean drain quantum and shorten time to get the V-P shunt operation,the mean days from implantation pumps to get V-P shunl was(57.00 ± 8.06) days. In 13 patients with Ommaya reservoir, 10 patients finished V-P shunt operation finally,3 patients gave up the shunt operation, shunt rate was 76.9%.In the treatment period , 4 patients had to change the Ommaya reservoir, secondary operation rate was 30.8%. Thirteen patients had the chance to get V-P shunt operation among 21 patients which got external ventricular drainage, 3 patients gave up the shunt operation, 5 patients died, shunt rate was 61.9%, 16 patients changed the ventricular drainage tube, sec-ondary operation rate was 76.2%. There was no significant difference in 3-month GOS between them (P ＞0.05 ). Conclusions Compared with external ventricular drainage, Ommaya reservoir has similar shunt rate.Ommaya reservoir has the less secondary operation rale, shorten the treatment days postoperative intracranial infection combined with hydrocephalus in patients with severe traumatic brain injury, so it should be popularized in clinic.

Objective: To study the chemical constituents in the roots of Aconitum bulleyanum Diels. Methods: The air-dried roots of A. bulleyanum were powdered and extracted by methanol with percolation. After removing the solvent under reduced pressure, the crude extract was dissolved in 1. 5％ HCl solution, and then basified to pH 9 by NaOH (5％) and extracted by ethyl acetate to ob-tain crude alkaloidal extract after ethyl acetate removal. The alkaloidal extract was isolated and purified by column chromatography, and their structures were identified based on spectral analysis ( 1 H-NMR, 13 C-NMR, MS) . Results:Totally 12 diterpenoid alkaloids were isolated from A. bulleyanum and characterized as foresaconitine (1), crassicauline A (2), chasmanine (3), talatisamine (4), 14-debenzoyl-franchetine (5), pengshenine A (6), crassicautine (7), yunaconitine (8), franchetine (9), liljestrandisine (10), transconitine B (11) and pseudoaconine (12). Conclusion:Compounds 3-7, 10-12 are isolated from this plant for the first time.

A case of the 12-year-old female patient with first relapsed acute lymphoblastic leukemia was reported. During the induction chemotherapy, the patient, transfused with whole blood and granulocytes, developed diarrhea and generalized macular rash. The skin biopsy showed some changes compatible with graft versushost disease (GVHD). Therefore, the related literature was reviewed, and the clinical features of transfusionassociated GVHD and the measures for its prevention and treatment were succinctly introduced.

Objective: To explore the possible relationships of adolescent personality traits, personality deviation and parental rearing pattern. Methods: 393 students from a high school in ShanDong were tested by PACL and EMBU. Re- sults: Generally, adolescent personality traits showed different profiles while factors of EMBU varied in different levels; Antisocial personality deviation was greatly influenced by parental warmth and understanding factor, father's punishment and rigor, father's overprotection. Schizoid personality deviation was mainly influenced by parental warmth and under- standing. Passive- aggressive personality dysfunction was influenced by father's warmth and understanding. Conclusion: Adolescent personality deviation is greatly influenced by parental rearing.

Objective To determine the causative organisms and antimicrobial susceptibility of community- and hospital-acquired pneumonia (CAP and HAP) in type 2 diabetes in Fujian Provincial Hospital. Methods The data of becteria spectrum and their drug susceptibility in patients with type 2 diabetes complicated by pulmonary infection were retrospectively analyzed in January 1995 to October 2006. Results The isolated bacteria of sputum culture of 494 cases included 73 gram-positive cocci(16.7%),139 gram negative bacilli(31.9%)and 224 fungus(51.4%).G+ cocci mainly included staphylococci,G-bacilli mainly included Klebsiella pneumoniae,Bowman immovability bacillus and Pseudomonas aeruginosa.In both CAP and HAP,fungus and G- bacilli were the dominant pathogens.The pathogenic bacteria were resistant to multi-antibiotics,and the resistant rates from HAP patients was higher than those from CAP. Of the bacterial strains isolated from blood culture,G-bacilli constituted 87.5%. Conclusions Fungus and G-bacilli were the dominant pathogens.Phlegm culture and drug sensitive test are helpful for reasonable use of antibiotics for patients with type 2 diabetes complicated by pulmonary infection in clinical practice.

Finite element analysis can be used to study the change of the structure and the interior field intensity of human and animal body organs and tissues with simulation experiment. We in our research used finite element analysis software to analyze and solve the spinal cord surface potential problems, and investigated the transmission features of signals generated by interneurons in spinal nerves which were related with body motion control and sensory processing. A three dimensional model of electrical source in rat spinal cord was built, and the influence on potential distribution on spinal cord surface caused by position changes of electrical source in transverse direction and dorsoventral direction were analyzed and calculated. We obtained the potential distribution curves of spinal cord surface and found that the potential distribution on spinal cord surface showed monotone. In addition, potentials of some registration points were smaller than that of registration points around.
