Eight new diaryltriazine derivatives containing 4-allylamino and 4-azido substitutes guided by molecular docking have been designed and synthesized based on our previous work. The evaluation of HIV inhibitory activity demonstrated that all compounds were potent against HIV-1 replication. The most active compound 7c exhibited activity against HIV-1 (IC50 = 0.034 micromol x L(-1), SI = 6,475) and the double mutant strain (IC50 = 9.39 micromol x L(-1)) in the micromolar range, which was more potent than nevirapine.

Saliva and blood were collected from two patients who had not received post exposure prophylaxis in the cities of Wenzhou and Xinning respectively. Both patients were confirmed as positive for rabies by detection of rabies virus specific nucleoprotein antibodies in the sera by Western Blot. However, rabies virus specific RNA was only identified in the saliva collected from the patient in Wenzhou. Furthermore, the isolate Zhejiang Wz0 (H) was obtained by inoculating one-day-old suckling mice. Both nucleoprotein (N) and glycoprotein (G) genes from the isolate were amplified by RT-PCR and sequenced. Phylogenetic analysis indicated that the isolate belonged to classic rabies virus, and shared a higher homology with the street viruses from dogs in the main endemic areas in China and the street virus from dogs in Indonesia than with other known strains. Further comparison of the deduced amino acid sequences between the isolate and the vaccine strains used in China showed that the virus had a higher level of homology with the vaccine strain CTN than with the other vaccine strains (3aG, PV, PM and ERA). In particular, amino acid residues substitutions located in antigenic site Ⅲ in the G protein, which could react with the neutralizing antibodies, were observed. These results suggested that the virus belonged to the classic rabies virus, and both N and G genes diverged from the current vaccine strains used in China at either the nucleotide or the amino acid level.

This study was designed to evaluate the effects of drilling through the growth plate and using adipose-derived stem cells (ADSCs) and bone morphogenetic protein-2 (BMP-2) to treat femoral head epiphyseal ischemic necrosis,which can be done in juvenile rabbits.Passage-four bromodeoxyuridine (BrdU)-labeled ADSCs were cultured,assayed with MTT to determine their viability and stained with alizarin red dye to determine their osteogenic ability.Two-month-old,healthy male rabbits (1.2 to 1.4 kg,n=45) underwent ischemic induction and were randomly divided into five groups (group A:animal model control;group B:drilling;group C:drilling & ADSCs;group D:drilling & BMP-2;and group E:drilling & ADSCs & BMP-2).Magnetic resonance imaging (MRI),X-ray imaging,hematoxylin and eosin staining and BrdU immunofluorescence detection were applied 4,6 and 10 weeks after treatment.Approximately 90％ of the ADSCs were labeled with BrdU and showed good viability and osteogenic ability.Similar results were observed in the rabbits in groups C and E at weeks 6 and 10.The animals of groups C and E demonstrated normal hip structure and improved femoral epiphyseal quotients and trabecular areas compared with those of the groups A and B (P＜0.01).Group D demonstrated improved femoral epiphyseal quotients and trabecular areas compared with those of groups A and B (P＜0.05).In summary,drilling through the growth plate combined with ADSC and BMP-2 treatments induced new bone formation and protected the femoral head epiphysis from collapsing in a juvenile rabbit model of femoral head epiphyseal ischemic necrosis.

PURPOSE: This study aimed to use a web-based survey to investigate the correlation between job satisfaction and marital quality and to identify the association of demographics with job satisfaction and marital quality. METHODS: Married nurses (N = 2,296) completed the questionnaires. Correlations and linear regression analyses were carried out. RESULTS: Both marital quality and job satisfaction were relatively low. Additionally, marital quality was positively correlated with job satisfaction. Age, marital status (in years) and average daily hours spent with spouse had positive impact on job satisfaction. Multiple linear regression analyses showed that age, monthly income, average daily hours spent with spouse and marital quality were positively associated with job satisfaction. CONCLUSION: Because of the shifts nurses working, there is little time for nurses to spend with their spouses and family. It is recommended that hospital leaders could provide more flexibility with nurses' shift choices so nurses can arrange their work-life balance better. Other considerations like reducing workload and reducing working hours should be promoted as options. Nurse managers could offer counseling services including strategies to cope with the balance between work and life. This effort could improve job satisfaction and reduce the rate of turnover of nurses.

Objeetive:To investigate the expression of HSP90 in cholangiocarcinoma tissues and cells,and the effect of 17-AAG on cholangiocarcinoma cell line.Methods:Forty patients with cholangiocarcinoma admitted to our hospital from July 2015 to July 2016 were selected as study subjects.Expression of HSP90 in cholangiocarcinoma tissues,paracancerous tissues and normal tissues was detected respectively.Cholangiocarcinoma cell lines were treated with different concentrations of 17-AAG,and expression of HSP90 and its effect protein HIF-1 α was detected.R esults:The total positive rate in cholangiocarcinoma tissues (82.5％) was higher than paracancerous tissues (35.0％) and normal tissues (20.0％)(all P＜0.05).The strong positive expression rate in cholangiocarcinoma tissues(37.5％) was higher than paracancerous tissues(10.0％) and normal tissues (5.0％)(all P＜0.05).There was no significant correlation between expression of HSP90 in cholangiocarcinoma tissues and invasion depth,lymph node metastasis (P＞0.05),but there was a significant correlation with TNM stage and tumor diameter (P＜0.05).With the increase of treatment concentration of 17-AAG,HSP90 α / β-actin and HIF-1 α / β-actin decreased,and there were significant differences in expression of HSP90α and its effect protein HIF-1 α in cholangiocarcinoma cell lines under different treatment concentrations (P＜0.05).Conclusion:HSP90 is highly expressed in cholangiocarcinoma tissues and cells and its expression is related to clinical stage and tumor diameter.17-AAG can down regulates the expression of HSP90 α and HIF-1 α in TE-1 cells,which plays a certain guiding role in clinical treatment.

This study aimed to examine the biocompatibility of calcium titanate (CaTiO3) coating prepared by a simplified technique in an attempt to assess the potential of CaTiO3 coating as an alternative to current implant coating materials.CaTiO3-coated titanium screws were implanted with hydroxyapatite (HA)-coated or uncoated titanium screws into medial and lateral femoral condyles of 48 New Zealand white rabbits.Imaging,histomorphometric and biomechanical analyses were employed to evaluate the osseointegration and biocompatibility 12 weeks after the implantation.Histology and scanning electron microscopy revealed that bone tissues surrounding the screws coated with CaTiO3 were fully regenerated and they were also.well integrated with the screws.An interfacial fibrous membrane layer,which was found in the HA coating group,was not noticeable between the bone tissues and CaTiO3-coated screws.X-ray imaging analysis showed in the CaTiO3 coating group,there was a dense and tight binding between implants and the bone tissues;no radiation translucent zone was found surrounding the implants as well as no detachment of the coating and femoral condyle fracture.In contrast,uncoated screws exhibited a fibrous membrane layer,as evidenced by the detection of a radiation translucent zone between the implants and the bone tissues.Additionally,biomechanical testing revealed that the binding strength of CaTiO3 coating with bone tissues was significantly higher than that of uncoated titanium screws,and was comparable to that of HA coating.The study demonstrated that CaTiO3 coating in situ to titanium screws possesses great biocompatibility and osseointegration comparable to HA coating.
