Baicalein-nicotinamide(BE-NCT)co-crystal was chosen as model drug to investigate the thermody-namic characteristics.Solubilities of BE in NCT solutions in ethyl acetate at different temperatures were deter-mined in order to explain the complexation behavior of BE-NCT co-crystal.Thermodynamic parameters of co-crys-tal formation progress were calculated.Ternary phase diagrams (TPDs)of the BE-NCT-ethyl acetate systems at various temperatures were established.The non-linear fitting equation according to 1 ∶1 complexation mechanism of BE-NCT co-crystal demonstrated a good correlation between calculated and experimental data (R2 >0.98). Co-crystal formation is a spontaneous process(ΔG°<0).Increase in temperature resulted in the increase of Ksp;decrease of K11 and a narrowed co-crystal zone.The degree of spontaneous reaction also decreased with increased temperature.The spontaneous reaction no longer carried out if the temperature reached T* =315 K sinceΔG°=0(ΔH°=-6.314 ×10 -2 kJ/mol;ΔS°=-0.200 5 J/mol.K).A drop in temperature favors the complexation between BE and NCT in ethyl acetate.Since NCT has higher solubility than BE in ethyl acetate;the TPDs of co-crystal was asymmetric.The DSC diagrams of products prepared via three presupposed methods confirmed that the BE-NCT co-crystal could be generated in solutions of nonstoichiometric compositions.

Objective To investigate the status of career resilience and job satisfaction among specialized nurses and to analyze the correlation between them.Methods Totally 288 specialized nurses were investigated with Career Resilience Scale and Minnesota Satisfaction Questionnaire.The correlation between career resilience and job satisfaction was analyzed using a Pearson correhtion analysis.Results The overall score of the career resilience was (37.12±4.78); the overall score of the job satisfaction was (68.51±7.87).They correlation coefficient between career resilience and job satisfaction was 0.310.Conclusions The level of career resilience and job satisfaction need to be enhanced among specialized nursing.There is a low to medium positive correlation between career resilience and job satisfaction.Measures should be carried out to enhance the nursing staffs' career resilience and to further improve their job satisfaction.

Objective To investigate the career resilience and its influencing factors among nurse specialists.Methods Totally 288 nurse specialists were investigated by General Information Questionnaire,Career Resilience Scale,Core Self-Evaluations Scale and Simplified Coping Style Scale.Results The score was 37.12±4.78 for career resilience,35.46±4.78 for core self-evaluations,23.57±5.2 1 for positive coping,and 9.39±3.74 for negative coping,respectively.There were statistic difference (P＜0.01) among the total score and 2 dimensions score of career resilience on different level of self-assessment of health among specialist nurses.Specialist nurses,career resilience had a obvious positive correlation with the age,nursing age,core self-evaluations,and positive coping(P＜ 0.01).The results of multivariate linear regression analysis showed that age,self-assessment of health,positive coping and core self-evaluations entered the regression equation of career resilience.Positive coping was a partial intermediate variable of core self-evaluations and career resilience.Conclusion The level of career resilience is medium and it should be enhanced among nurse specialists.The age,self-assessment of health,positive coping and core self-evaluations are possible influencing factors of career resilience.And core self-evaluations can improve career resilience of specialist nurses via the effects of positive coping.

Objective To investigate the diagnosis of intracranial artery fenestration and its other vascular anomalies with CT angiography ( CTA ) . Methods The image data of 653 patients examined with head CTA and 39 patients diagnosed as intracranial artery fenestration in Zhongshan Hospital Affiliated to Sun Yat-sen University from January 2013 to January 2014 were analyzed retrospectively. The incidence, location,morphology of intracranial artery fenestration, and other vascular anomalies were analyzed. Results (1) In 653 patients,39 (5. 97%) with 41 artery fenestrations were detected. The detection rates of basilar artery fenestration was 3. 37% (n=22),vertebral artery fenestration was 0. 31% (n=2),anterior cerebral artery fenestration was 1. 22% (n =8),anterior communicating artery fenestration was 0. 61%(n=4),and middle cerebral artery fenestration was 0. 76% (n=5),respectively. The post-circulation fenestration was mainly convex lens type (66. 67%,n =17),the anterior-circulation fenestration was mainly fissure type (76. 47%,n=24),and there was significant difference (χ2=7. 411,P<0. 05). (2) In the 39 patients,22 complicated other vascular anomalies. Most of them were unilateral or bilateral fetal-type posterior cerebral arteries (n=10),and followed by aneurysms (n=5). The locations of 5 aneurysms were far from the fenestration,3 located in the communicating segment of internal carotid artery,1 in the top of basilar artery,and 1 in the M2 segment of bilateral middle cerebral arteries. Conclusion CTA can intuitively and clearly reveal the intracranial artery fenestration and other vascular anomalies. But there is no significant correlation between arterial fenestration and vascular anomalies.

Objective To study the effect of calcitonin on the expression of vascular endothelial growth factor in femoral fracture healing in ovariectomized rats .Methods 80 female rats of 3 months old were randomly divided into four groups :Sham operation group(Sham ,10 cases);Ovariectomized operation group(OVX ,10 cases);Ovariectomy+ fracture+ salinegroup(Control ,30 cases) and Ovariectomy+ fracture +calcitonin group(Experimental ,30 cases) .Rats in Sham group and OVX group were performed ovari-otomy and killed after 4 weeks ,femoral bone mineral density was measured .For rats in Control group and Experimental group ,right middle femoral facture was performed 4 weeks later after ovariectomy .Calcitonin(16 IU/kg)were injected subcutaneously once per 2 days in Experimental group ,while those in Control group were given equal volume of normal saline .Rods in these two groups were killed after 3 ,6 ,9 weeks(10 at a time) ,femoral bone mineral density(BMD)was measured;hematoxylin-eosin staining and im-munohisto-chemical staining were performed at the 3th ,6th and 9th week after fracture ,respectively .Results Compared with Sham group ,rats weight in OVX group gained more(P< 0 .05) ,and BMD in OVX group significantly decreased more(P< 0 .05) .HE staining ,at the 3th week after fracture ,endochondral ossification domained in fracture healing ,and no significant difference existed (P>0 .05)in BMD .At the 6th week after fracture ,bone trabecula in both groups arranged in order ,compared with the control group ,BMD in experimental group increased significantly(P<0 .05) .At the 9th week after fracture ,bone trabecula in both groups arranged closely ,BMD in both groups showed significant difference(P<0 .05) .There was no significant difference of vascular endo-thelial growth factor(VEGF)between experimental group and control group at the 3th ,6th ,9th week after fracture(P>0 .05) .Con-clusion The results suggest that calcitonin treatment could enhance the bone mineral density significantly after fracture ,but it has no impact on the expression of VEGF in osteoporotic fracture healing .

Objective To conduct a single-center retrospective analysis on the distribution characteristics and prevalence of idiopathic membranous nephropathy (IMN) patients diagnosed with pathology for the past 16 years,to investigate diagnostic and differential diagnostic value of serum antiphospholipase A2 receptor antibodies (PLA2R-Ab),and to evaluate the correlation between PLA2R-Ab and clinical disease activity.Methods (1) 6996 biopsy-proven primary glomerular nephropathy (PGN) patients,including 1567 IMN cases,admitted to the First Affiliated Hospital of Xi'an Jiaotong University from January 2000 to December 2015 were involved.Demographics and pathological type were gathered from all patients.(2) 433 cases receiving renal biopsy and testing PLA2R-Ab from June 2015 to December 2015 were involved,with their clinical and laboratorial data being collected.During the period patients' follow-up time,therapeutic schedule and laboratory results were recorded.Results (1) IMN accounted for 22.4％ of primary glomerular disease,and patients above 40 years old accounted for more than 60％ of the IMN.(2) The sensitivity and specificity of serological PLA2R-Ab were 58.1％(95％CI 47.0％-68.5％) and 98.6％(95％CI 95.6％-99.6％) respectively.PLA2R-Ab positive rate was affected by immunosuppression therapy.(3) The PLA2R-Ab titers wasn't correlated with 24-hour urinary protein (r=-0.017,P=0.887),serum albumin (r=-0.072,P=0.549) and urinary red blood cell count (r=-0.030,P=0.802).There was no difference between PLA2R-Ab positive positive and PLA2R-Ab negative on proportion of IMN pathological stage Ⅰ-Ⅱ (P ＞ 0.05).Thirteen cases of patients with PLA2R-Ab positive were all prescribed glucocorticoid combined with immunosuppressant.After (2.21± 1.09) months,the decrease of PLA2R-Ab titers was in accordance with 24-hour urinary protein quantity descending and serum albumin ascending (P ＜ 0.05).Condusions The incidence of IMN increase year by year,especially in the mid-aged and the elderly.Serum PLA2R-Ab correlates not with IMN pathological stage,but with the development of IMN.Monitoring PLA2R-Ab titers individually may access the efficiency of treatment.

Adjuvant radiotherapy (RT) can improve the rate of loco-regional control for patients with gastric cancer (GC),while the selection of patients plays a key role.As the research moves along,several relatively comprehensive molecular classifications emerged such as the TCGA classification and the ACRG classification.Studies have demonstrated that molecular classifications are closely related to the clinicopathologic characteristics,prognosis and treatment response.However,there is not recognized molecular classification of GC presently.It is a great challenge for radiation oncologists to make use of the individual bioinformation and accurately select patients who would benefit from RT.Meanwhile,precision RT could also be achieved with the prediction of radiosensitivity,combination of RT with targeted therapy and the application of ctDNA within the field of RT.
