A series of multinuclear diethylenetriamine ligands were synthesized and used as artificial nuclease enzyme model. Target compounds were characterized by 1H NMR, 13C NMR, IR and ESI-MS. Preliminary studies on the cleavage of pUC19 DNA in the presence of metal complexes have also been performed and the results revealed that these complexes could act as powerful catalysts for the cleavage of pUC19 DNA after 48 h under physiological conditions. The hydrolytic cleavage mechanism of DNA plasmid by title compound was confirmed by T4 DNA ligase experiment.

Objective To explore the relationship between severe(≥grade 3 ) radiation pneumonitis (RP) and dose-volume histogram (DVH) parameters for non-small cell lung cancer (NSCLC) treated with three-dimensional conformal radiation therapy (3-DCRT). Methods Ninety-four patients with NSCLC treated with 3-DCRT were retrospectively analyzed. Clinical parameters were analyzed. DVH parameters analyzed were V20, V30, V40,mean lung dose (MLD),normal tissue complication probability(NTCP) ,and total dose. Results Age,sex, Karnofsky scored, performance status, forced expiratory volume in 1 second,presence of weight loss, preexisting lung disease, history of thoracic surgery, and history of chemotherapy were not associated with the risk of severe RP(P>0.05). However,in univariate analyses, V20, V30, V40, MID and NTCP were associated with severe RP(P<0.01). In multivariate analysis, MID and V30 were variable associated with severe RP(P<0.01). The severe RP was 0 when MLD < 10 Gy and 21%(8/39) when MLD between 10 Gy and 20 Gy but 35%(7/20) when MLD > 20 Gy,it was 0 when V30 < 25% and 12%(4/33) when V30 between 25% and 35% but 38%(11/29) when V30 >35%. Conclusion MLD and V30 are significant predictive factors for severe RP and they should be limited to ≤20 Gy and ≤ 35% in order to reduce severe RP.

OBJECTIVE:To provide reference for rational use of drugs in patients with mental disorders. METHODS:In retro-spective investigation,47 386 prescriptions of psychiatric department in our hospital during Sept. 2013 to Aug. 2014 were analyzed statistically. RESULTS:Totally 39 496 cases were enrolled in the 47 386 prescriptions. The median age of patients was 31.42,with male to female ratio of 1:1.07;they were diagnosed as schizophrenia and other mental disorder,accounting for 65.34%,and fol-lowed by mood disorders,accounting for 15.20% . They were mainly given single drug and two-drug use,accounting for 30.80%and 61.68%respectively. Clozapine,quetiapine,risperidone were top 3 prescription drugs in the list of frequency;olanzapine,que-tiapine,risperidone were top 3 drug in the list of consumption sum. Among top 20 psychiatric prescription drugs,there were 7 kinds of drugs for schizophrenia and other psychiatric disorders,3 kinds of drugs for mood disorders. CONCLUSIONS:The use of antipsychotic drugs in our hospital is rational basically.

Objective To observe the clinical efficacy of needling the three tongue points plus plum-blossom needle in treating aphasia after ischemic stroke. Method Sixty patients with aphasia after ischemic stroke were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by needling the three tongue points plus treating the Jiao’s Language Zone 1 with plum-blossom needle, while the control group was by regular body acupuncture. After 2 treatment courses, the language function score (spontaneous speech fluency, repeating, and reading scores) were observed, and the clinical efficacies were compared.Result After intervention, the spontaneous speech fluency, repeating, and reading scores were significantly changed in both groups (P<0.01). After intervention, there were significant differences in comparing the speech fluency, repeating, and reading scores between the two groups (P<0.05). The total effective rate was 86.7% in the treatment group versus 76.7% in the control group, and the difference was statistically significant (P<0.05).Conclusion Needling the three tongue points plus plum- blossom needle is an effective method in treating aphasia after ischemic stroke.

Objective:To explore the therapeutic effect of the extraction of bone-melon injection for the earlier fracture.Method:100 patients with early fracture were divided into two groups.50 cases in the treatment group used the extraction of the bone-melon injection and 50 cases in the controlled group used compound ossotide injections.Their curative effects were judged according to their healing time,level of relieving pain and functional recovery condition.Result: The patients in the treatment group healed earlier(P

Objective To observe the clinical efficacy of navel acupuncture in treating lumbar spinal stenosis. Method A total of 120 patients with lumbar spinal stenosis were randomized into a treatment group and a control group, 60 cases each. The treatment group was intervened by navel acupuncture based on syndrome differentiation of traditional Chinese medicine, while the control group was intervened by oral administration of Bulleyaconitine A tablets, 10 d as a treatment course, for successive 2 courses. The Visual Analogue Scale (VAS) was observed before and after the intervention, and the clinical efficacies were compared.Result The total effective rate was 98.3% in the treatment group versus 76.6% in the control group, and the between-group difference was statistically significant (P<0.01). The VAS scores were significantly changed after the intervention in both groups (P<0.05); the VAS score in the treatment group was significantly different from that in the control group after the treatment (P<0.05).Conclusion Navel acupuncture is an effective approach in treating lumbar spinal stenosis.

Cantharellus Adans. ex Fr., a member of the Cantharellaceae, Cantharellales, Homobasidiomycetes, Basidiomycota, is a widely distributed macro-fungal genus with an independent evolutionary lineage. It currently includes 65 species, of which 9 were recorded in China. In this article, research history of the genus was briefly reviewed and some controversial conclusions, especially the demarcation and naming of some taxa, discrimination among similar species, problems on C. cibarius Fr. and C. tubaeformis Fr.: Fr. complex, as well as their ecological conservation and bionic cultivation, are discussed based on the authors’ findings. Proposals for further research on biodiversities and sustainable utilizations were put forward at last.

Objective To isolate and identify viruses from fecal samples of tree shrew with diarrhea.Methods Fecal sample supernatant of tree shrew with diarrhea was inoculated to three cell lines ( Vero, LLC-MK2 and KMB17 ) , and the cytopathic effects on the cells were observed.The infectious particles in the culture supernatant were further ana-lyzed by transmission electron microscopy ( TEM) , genomic RNA-PAGE, rotavirus detection kit, amplification of S1 com-plete segment and bioinformatics analysis.Results Constant cytopathic effects were induced in Vero, LLC-MK2 and KMB17 cell lines after three passages of culture.The results from TEM, RNA-PAGE and rotavirus analysis indicated that they belong to reoviruses.Analysis of the S1 segments revealed that the S1 sequence from KMB17 cell culture had the high-est homology with that of prototype isolate T1L (85%nucleotide homology and 90%amino acid homology), therefore this isolate was named as type I reovirus.The other two S1 sequences from LLC-MK2 and Vero cell culture were identical to have 85%nucleotide homology and 92%amino acid homology with the prototype isolate T3D, named as type III reovirus. Phylogenetic analysis indicated that the isolates in this study are evolutionally adapted to tree shrews.Conclusions It is the first report here that 2 genotypes of Tupaia orthoreovirus are isolated and identified from one fecal sample via three cell lines and viral S1-specific primers, which provides useful guidelines for the isolation and identification of other reoviruses from tree shrew or other hosts.

ObjectiveTo investigate the therapeutic effect of long snake moxibustion on different types of lumbago.Method Patients with lumbago of kidney deficiency, dampness-heat, blood stasis or cold-dampness type were enrolled, 30 cases each. Pre-treatment lumbago scores, post-treatment lumbago scores and clinical therapeutic effects were compared. Statistical analysis was carried out.ResultA marked therapeutic effect was produced in every group of patients after two courses of treatment. The total efficacy rate was 93.3% in lumbago of kidney deficiency type, 86.7% in lumbago of dampness-heat type, 90.0% in lumbago of blood stasis type and 96.7% in lumbago of cold-dampness type; there was no statistically significant difference (P>0.05). There was a statistically significant post-treatment difference in the pain score between the groups of patients (P<0.05).ConclusionLong snake moxibustion has a very good therapeutic effect on every type of lumbago. The therapeutic effect is best in patients with lumbago of cold-dampness type.
