Correlation of Treatment Compliance,Treatment Attitude and Belief,and Quality of Life in Community Hypertensive Patients

Objective:To explore the relationship between treatment compliance,treatment attitude and belief,and quality of life in patients with hypertension in the community,and to provide evidence for improving their quality of life.Methods:A convenient sampling method was used to survey 250 patients with hypertension who met the inclusion criteria using the General Questionnaire,Treatment compliance,Treatment Attitudes and Beliefs,and Quality of Life Scale.Results:The total score of treatment compliance of hypertension patients in the community was(91.678±11.431),treatment attitude and belief score(70.407±9.008),quality of life score(113.599±13.511),Pearson correlation analysis showed that the treatment compliance of hypertension patients was positively correlated with quality of life(r=0.433,P<0.01),and treatment attitude and belief were positively correlated with quality of life(r=0.463,P<0.01).Conclusion:The quality of life of patients with hypertension in the community is related to treatment compliance and treatment attitudes and beliefs.

Transitional care for patients with chronic obstructive pulmonary disease

Objectives:To observe the effects of transitional care on the quality of life of chronic obstructive pulmonary disease(COPD)patients.Methods:A total of 114 COPD patients were recruited from the First Affiliated Hospital,Sun Yat-sen University,Guangzhou,China and divided equally into an intervention group and control group.Following discharge,patients from the intervention group recieved threemonths intervention in addition to regular nursing care,while control group patients received regular nursing care only.Patients’quality of life was measured using the St.George’s respiratory questionnaire(SGRQ),the 12-item General Health Questionnaire(GHQ-12)and body mass index(BMI).Results:The symptoms section score,the activity section score,the impacts section score,the total score and the rate of mental disorders were significantly changed after the intervention while there was no statistical difference in BMI between groups.Conclusions:Transitional care can improve health-related quality of life in COPD patients who have recently suffered an exacerbation.

Bandwidth expansion and pulse shape optimized for 10 PW laser design via spectral shaping

We demonstrated a scheme of bandwidth expansion and pulse shape optimized to afford 10 PW laser design via spec-tral shaping,which uses the existing Nd:glass amplifier chain of the SG PW laser.Compared to the amplified pulse with a gain-narrowing effect,the required parameters of injected pulse energy,spectral bandwidth,and shape are analyzed,to-gether with their influence on the system B-integral,energy output capability,and temporal intensity contrast.A bandwidth expansion to 7 nm by using LiNbO_(3) birefringent spectral shaping resulted in an output energy of 2 kJ in a proof-of-principle experiment.The results are consistent with the theoretical prediction which suggests that the amplifier chain of SG PW laser is capable of achieving 6 kJ at the bandwidth of 7 nm and the B-integral<π.This will support a 10 PW laser with a compressed pulse energy of 4.8 kJ(efficiency=80%)at 480 fs.

Complementary feeding patterns among ethnic groups in rural western China

Objective： This study investigated complementary feeding practices among four ethnic groups（Han, Uygur, Tibetan, and Zhuang） based on a cross-sectional survey in rural western China. Methods： In 2005, a stratified multistage cluster random sampling method was used to recruit 9712 children（7411 Han, 1032 Uygur, 678 Tibetan, and 591 Zhuang） between 6 and 35 months of age and their mothers from 45 counties in 10 provinces（autonomous regions, municipalities） in western China. Results： The rates of early introduction（before 6 months） of complementary foods in four ethnic groups（Han, Uygur, Tibetan, and Zhuang） were 71.30%, 95.95%, 82.40%, and 72.30%, respectively. The Infant and Child Feeding Index（ICFI） for Uygur and Tibetan children was lower than that for Han children at all age groups. Uygur children were more likely to have unqualified ICFI compared with Han children in a multivariate logistic regression（odds ratio（OR）=5.138, 95% confidence interval（CI）： 4.340–6.084）. A higher level of maternal education, greater family wealth, and the availability of complementary feeding educational materials decreased the likelihood of an unqualified ICFI. The nutritional status of children（Han, Tibetan, and Zhuang） with qualified ICFI was better than that for children with unqualified ICFI. Conclusions： Appropriate interventions are required to improve complementary feeding practices in rural western China.

Structural, ferromagnetic, and optical properties of Fe and Al co-doped ZnO diluted magnetic semiconductor nanoparticles synthesized under high magnetic field

In this study, 2% Fe and 3% Al co-doped ZnO nanoparticles were synthesized using a hydrothermal method under high magnetic field (HMF). The influences of HMF on the structural, optical, and ferromagnetic properties of Fe and Al co-doped ZnO nanoparticles were characterized and analyzed. The single-phase wurtzite structure of the synthesized samples was confirmed using X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), and Raman spectroscopy analysis. The application of HMF decreases the particle size of the spherical nanocrystal as observed by scanning electron microscopy (SEM). Optical analysis indicated that the absoqjtion edge shifted towards a higher wavelength (red shift). The nanoparticles synthesized under the HMF exhibited high room temperature ferromagnetism (RTFM) performance because of the high oxygen vacancy (VO) content as revealed by X-ray photoelectron spectroscopy (XPS), which was in agreement with the prediction of the bound magnetic polarons theory.
