Objective To explore the effects of recombined human growth hormon-enhanced early enteral nutrition on healing of the patients after operation for sereve abdominal trauma.Methods 60 patients with severe abdominal trauma were randomly divided into PN(n=20),EN(n=20) and EN+ rhGH(n=20) groups.Nutrient status and immune function of 3 groups were detected on the postoperative day 1,7 and 10.Results EN+ rhGH group showed more effective process than EN and PN groups in improving postoperative nutrient status,immune function and nitrogen balance,whose indexs except CD8 changed significantly on the postoperative day 7 and 10 than that in PN group(P

Objective To investigate the protective effects of green tea polyphenols(GTPs)on dopamine neuron loss in substantia nigra concomitant with a depletion of dopamine in corpus striatum induced by the N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)in mice as a model of Parkinson disease.Methods Male C57BL/6 mice were intraperitoneally injected with saline + saline(group A),saline + GTPs(group B),saline+MPTP(group C)and GTP+MPTP(group D)at 2-hour intervals for a total of 3 doses for MPTP and 5 doses for GTPs(10 or 50 mg/kg delivered).The animals were sacrificed 7 d after the last injection.Levels of dopamine and its metabolites in the corpus striatum were measured with high-performance liquid chromatography with an electrochemical detector(HPLC-ECD).Results Level of dopamine and its metabolites in the corpus striatum in group C decreased significantly compared with group A or B;however,those in group D(both 10 and 50 mg/kg)prevented these effects.Conclusion GTPs can protect the dopamine neurons from loss in MPTP-induced mice.

Objective: To explore the impact and mechanism of disease management of caregivers on self-management behaviors among patients with chronic heart failure. Methods: A total of 231 dyads of outpatient chronic heart failure patients and their caregivers were assessed by caregivers contribution to self-care of heart failure index (CC-SCHFI), self-care of heart failure index (SCHFI) and Atlanta heart failure knowledge test (AHFKT-V2). IBM SPSS 22.0 was used to conduct the paired t test and Pearson correlation analysis. LISREL 8.80 was used to conduct the path analysis. Results: There were significant differences between caregivers and patients in maintenance behavior (P=0.015), management behavior (P=0.023) and self-efficacy (P=0.001). There was no correlation between caregiver self-efficacy and patient heart failure knowledge and skill, but other variables were positively correlated, and r value ranged from 0.129 to 0.575 (P<0.05). Patient self-management behaviors were directly influenced by caregiver disease management, patient heart failure knowledge and skill and patient self-efficacy, and indirectly influenced in part by caregiver disease management through patient heart failure knowledge and skill and patient self-efficacy. Conclusion: Caregiver disease management not only can directly influence patient selfmanagement behaviors, but also can indirectly influence patient self-management behaviors through patient heart failure knowledge and skill and selfefficacy. Health care workers should carry out family-centered health education, and help caregivers actively participate in disease management of patients with heart failure; for those patients whose caregivers can't change their disease management behaviors, health care workers should also improve their selfmanagement behaviors by improving patients' heart failure knowledge and skill and self-efficacy.

Root canal therapy is the most efficient way to treat pulptitis and periapical inflammation, which can clear infections of root canal systems, fill the root canal firmly, and avoid reinfection. However, the variations in root canal morphology and complexity of infection confer difficulty in thoroughly eliminating microorganisms and their by-products in the root canal system, especially in the root apex area (including the top one-third of the root canal and periapical tissue), which is described as the hardest area to clean during endodontic treatment. Infection is difficult to remove entirely because the apex area is hard to approach using dental instruments and because of the existence of special morphological structures, such as apical ramification, intercanal anastomoses, and lateral branch of root canal. This review gives a brief introduction of the characteristics and difficulties of apical infection and knowledge on how to control such infections, including root apex preparation, irrigation and disinfection, and root canal filling.

Objective To investigate the key points in the nursing work of esophageal waterperfused high-resolution manometry (WHRM).Methods Summarized the nursing experiences before,during and after WHRM of 153 patients.Results Only 5 cases could not finish the test due to failure of intubation.23 cases complained about nasopharyngeal discomfort but follow-up monitoring was unremarkable.Conclusion In order to ensure the completion of WHRM,nursing cooperation requires serious assessment and preparation before manometry,intimate observation of patients' condition during manometry,and keep the catheter disinfection after manometry.

Objective To explore the changes of different echocardiographic indices in patients receiving catheter ablation for atrial fibrillation with different outcomes. Methods 75 patients received catheter ablation for atrial fibrillation during the period of January 2012 to February 2014. Before and 6 monthes after ablation , all the patients were examined left atrial volume index (LAVi), left atrium pressure (LAP), and left atrial ejection force (LAF) with echocardiography. Then after 6 months, according to the outcomes of the procedure, we divided the patients into two groups and compared the changes of these three parameters. Results In sinus group, LAVi decreased while LAF increased after treatment [LAVi: (29.3 ± 1.9) vs. (41.2 ± 9.3), LAF:(1.31 ± 0.61) (kg·cm)/s2 vs. (0.83 ± 0.22) (kg·cm)/s2, P < 0.05]; But LAP did not change [(55.7 ± 23.3)mmHg vs. (58.9 ± 18.6)mmHg, P > 0.05]; while in recurrent group, there were no changes in LAVi, LAP, and LAF after treatment (P > 0.05). Conclusions Radiofrequency catheter ablation is safe and effective in treatment of atrial fibrillation, resulting in significant improvements in left atrial volume and cardiac function.

The paper analyzed the structural characteristics, biological characteristics, infection symptoms, detection methods and corresponding protective measures of Zika virus, as well as analyzed coping strategies for high-risk groups (pregnant women and infants).Zika virus is nonsegmented, single-stranded,and positive-sense RNA genome with fast spreading.Fever and arthralgia are its common symptoms.Currently, it can be tested in serum, urine and saliva samples.The virus protection can be classified into overall control from government, total prevention from society and individual protection according to the guidelines.It is severe to prevent and control epidemic situation of Zika virus, and it needs to improve the whole nation's prevention and treatment ability, and it can improve other social problems through Zika virus prevention.
