ObjectiveTo identify the status of quality of life in breast cancer patients and explore the impact of environmental factors on quality of life in breast cancer patients receiving chemotherapy. MethodsTotally 201 primary breast cancer patients undergoing chemotherapy after surgery were investigated.Self-developed demographic and clinical character investigation questionnaire,WHO Disability Assessment Schedule Ⅱ(WHODAS Ⅱ),and environmental factors in International Classification of Functioning Disability and Health(ICF)core sets for breast cancer patients were adopted to collect relevant data. ResultsBreast cancer patients had different levels of difficulties on each domain of WHODAS Ⅱ.Multiple stepwise regression analysis demonstrated that“material and emotional support and interrelationship with friends”, “social security service,system and policies” and“social norms,practices and ideologies” were factors influencing quality of life of breast cancer patients. ConclusionsIn addition to the strengthen of rehabilitation exercise training,nurses should advocate more services from society through policy making,prompt public awareness and scientific cognition,as well as construct effective nursing interventions to help enlarge social support resources and improve social support level.

Objective:To observe expression and diversity of glycogen synthase (GSK)-3 and ribosome S6 protein kinase (P70S6K) in skeletal muscle of insulin resistance (IR) rat induced by high fat food and to approach the effect and significance of GSK-3 and P70S6K in IR occurrence.Methods:Forty Wistar rats aged four-week were randomly divided into normal control, high-glucose, high-fat and high-fat high-glucose groups. 8 weeks after feeding, insulin sensitivity of the rats was evaluated by hyperinsulinism euglycaemic clamps technique (ring clamp experiment), GSK-3 and P70S6K in rat skeletal muscle were measured by Western blot and epididymis fat pad weight, blood glucose, insulin, triglyceride (TG), cholesterin (TC), free fatty acids (FFAs) and hsCRP levels were also determined.Results:IR was induced, body weight (P

Objective To evaluate the prevalence of extraosseous findings on integrated CT images of routine SPECT/CT bone imaging and its clinical incremental values. Methods A total of 843 patients (470 males, 373 females, age range: 26-92 years) who underwent SPECT/CT bone imaging during May 2013 to December 2015 were enrolled in this retrospective study. A modified C-RADS was used to classify the extraosseous findings to E1, E2, E3 and E4. χ2 test was used for data analysis. Results The CT images in 78.6%(663/843) of patients were normal or with no additional clinical significance (E1 and E2), and those in 21.4%(180/843) of patients might need further assessment (E3 and E4). The rate of E4 extraosseous findings in patients with malignancy was higher than that in patients without malignancy: 9.5%(59/622) vs 5.0%(11/221); χ2=4.352, P<0.05. There was no significant difference of the rate between genders: 8.5%(40/470) in males vs 8.0%(30/373) in females; χ2=0.510, P>0.05. With age increasing, the prevalence of E4 finding increased and the rate was the highest in the patients over 80 years old (125%, 16/128). Seventy patients had E4 findings and chest masses and nodules were the most common, followed by the abdominal or pelvis lymph node enlargements. Conclusions Potentially important extraosseous findings are common on SPECT/CT. Systematic reviewing CT images and communicating the important unexpected findings to clinical physicians could enhance its clinical incremental values.

Objective To investigate the effect of brain natriuretic peptide (BNP) on serum angiotensin-converting enzyme (ACE) 2 levels in acute heart failure patients with reduced ejection fraction (HFrEF). Methods A total of 106 patients with acute HFrEF were selected, and were divided randomly into control group and trial group. The control group was under routine treatment, while the trial group was under routine treatment combined with lyophiluzed recombinant human BNP for 24-hour. Cardiac functional parameters were measured by echocardiography both at the enrollment and the end of 7-day treatment. Serum levels of ACE2 and N-terminal pro-BNP (NT-proBNP) were determined using commercially available ELISA kits at the enrollment, the end of 24-hour treatment, and the end of 7-day treatment,respectively. Results A total of 103 patients with acute HFrEF were enrolled (control group=51, trial group=52). There were no significant differences in the use of drugs (e.g., aspirin) and serum biochemical indices (e.g. cardiac troponin I, creatinine) before treatment between these two groups. Compared to systolic blood pressure (SBP) at admission, SBP on the second day after treatment were significantly decreased in two groups (P<0.05). Compared to left ventricular ejection fraction (LVEF) at admission, LVEF values were significantly elevated on the seventh day after treatment in two groups ( P<0.05). There were no significant differences in SBP, diastolic blood pressure (DBP), and LVEF at admission between these two groups (P>0.05);there were also no significant differences in DBP on the second day after treatment, and LVEF on the seventh day after treatment (P>0.05), while SBP was significantly higher on the second day after treatment in control group than that of trial group (P < 0.05). Serum levels of NT-proBNP were decreased with the prolongation of time in two groups. Serum levels of ACE2 were decreased with the prolongation of time in control group, while were increased initially following decreased (which were still higher on the seventh day after treatment than that at admission) with the prolongation of time in trial group. Serum levels of NT-proBNP were higher after 2 days treatment or 7 days of treatment in control group than those of trial group, while serum levels of ACE2 were decreased after 2 days of treatment or 7 days of treatment in control group than those of trial group (P<0.05). Conclusion Patients with acute HFrEF may benefit from BNP by increasing serum ACE2 levels.

Objective To study the clinical significance of MR imagings features in the diagnosis on central neurocytoma ( CNC ) . Methods From January 2010 to December 2012,9 patients with CNC were analyzed and examined by MRI before surgery,then received postoperative pathology examination. Results CNC were in the left lateral ventricle of 9 patients, closely linked with the Monro hole, of which 4 cases were in the first 2/3 of central ventricle of the left lateral ventricle,3 cases in the septum pellucidum and growth to bilateral ventricles,2 cases of infiltrating in the septum pellucidum and base side adhesion. For CNC,MRI signal was not uniform,solid part T1WI showed equal or slightly low signal,multiple cysts and signal cord like structure with the ventricular wall and septum pellucidum adhesion. By contrast-enhanced CT scan,there were the solid part heterogeneous obvious enhancement in 4 cases,moderate and slight uneven enhancement in 3 cases and 2 cases respectively. Uniform size,round or oval cells were showed by HE staining,and the synaptophysin was positive in 6 ca-ses by immunohistochemical staining,positive expression of glial fibrillary acidic protein in 3 cases. After operation,3 patients were lost to fol-low up,for 6 cases were followed up,survival of 2 cases in 3 years,4 cases in 2 years. Conclusion The results suggest that MRI display is located near the lateral ventricle central Monro hole before and lesions suggestive of CNC in young patients. For most CNC,synaptophysin has positive expression by immunohistochemical staining.

Background and purpose:Postoperative sore throat (POST) is one of the common complaints of patients after radical thyroidectomy. Tracheal intubation is the main cause of POST. This study compared the effect of intubation with visual endoscopy and general laryngoscope on POST in patients undergoing radical thyroidectomy. Methods:One hundred patients (18-60 years, ASAⅠ-Ⅱ) undergoing elective radical thyroidectomy were randomized into two groups:patients in group A (n=50) were intubated with visual endoscope while patients in group B (n=50) were intubated with general laryngoscope. Endotracheal tube cuffs pressure was maintained at 20mmHg in all patients. Visual analogue scale (VAS) and Bruggrmann comfort scale (BCS) were recorded at the time points of 1, 6 and 24 h after extubation. Results:Compared with group B, the incidence of POST in group A was signifcantly reduced (42%vs 64%, P=0.027). The VAS of group A was lower than that of group B (3.05±1.56 vs 4.25±1.30, 3.05±1.56 vs 4.01±1.98, 2.72±1.77 vs 3.31±1.12) (P<0.05). The BCS of group A was higher than that of group B (0.99±0.46 vs 0.69±0.30, 1.95±0.47 vs 1.51±0.58, 2.82±0.87 vs 2.31±0.72) (P<0.05). Conclusion:Using visual endoscopic intubation can reduce the incidence of the POST in patients undergoing radical thyroidectomy.

AIM: To observe pathomorphological changes in cerebral cortex and hippocampus in the mouse with synthetic vascular dementia. METHODS: The synthetic vascular dementia model was produced in the mouse. Animals were killed 7 d, 15 d, and 30 d after the operation, brain tissues were removed and embedded in paraffin. Section of 8?m thickness were stained with hematoxylin-eosin(HE) and Nissl methods, and observed with light microscope. RESULTS: The cerebral cortex in the mouse became thinner on the seventh day, karyopyknosis in partial nervous cells was formed, the number of local neurons was reduced, sieve structure was observed, and glial cells proliferated, with the similar results 15 d and 30 d after operation. Model mouses hippocampal cells in CA 1 area were reduced and almost disappeared 30 d after operation. At the same time, glial cells were abundantly proliferated, tubercles were formed. Cells in CA 2, CA 3 area were also reduced and hippocampal sclerosis occurred. CONCLUSION: Delayed necrosis of hippocampal pyramidal cells may be the pathological basis of ischemia cerebral vascular dementia.
