ObjectiveTo explore the methods to improve the social support of HIV/AIDS patients in order to improve their quality of life. Methods115 cases of HIV/AIDS patients beginning to receive the anti-viral therapy were given nursing intervention.Social support rating scale (SSRS),quality of lifeKarnofsky scale were adopted to evaluate the social support and quality of life before and 3 months after nursing intervention. ResultsThe social support and quality of life of patients improved after intervention compared with those before intervention,and with improvement of social support,the quality of life was accordingly increased. ConclusionsSocial support under nursing intervention help to improve quality of life of HIV/AIDS patients,and can support evidence for education and strategies implementation of treatment compliance for HIV/AIDS patients receiving antiretroviral therapy.

Objective: To investigate the prevalence of metabolic disorder among the high school students in Guangzhou. Methods: A cross-sectional study among 4 620 high school students selected with stratified cluster sampling was conducted in Guangzhou. Height, weight, blood pressure, fasting plasma glucose (FPG) and serum lipid of TC, TG were measured. Household socioeconomic status, medical history, physical activities as well as personal diet and study habits were acquired with structured questionnaire. Results: The prevalence of central obesity was 11.5%. The overall prevalence of IFG and DM was 6.9%. The overall prevalence of both hypercholesteremia and hypertriglyceridemia was 13.4%. The prevalence of hypertension was 11.6%. With multivariable logistic regression, the results showed that: fast eating was associated with increased risk of central obesity (OR=1.79, 95%CI=1.47-2.18) and hypercholesteremia/hypertriglyceridemia (OR=1.27，95%CI=1.04-1.54). While students who ate slow had low risk of central obesity (OR=0.47, 95%CI=0.33-0.68), hypercholesteremia/hypertriglyceridemia(OR=0.71, 95%CI=0.54-0.94) and hypertension (OR=0.65, 95%CI=0.49-0.88). Students with sugar-sweetened beverages once a day or more had higher risk of central obesity (OR=1.60, 95%CI=1.08-2.38) while students without sugar-sweetened beverages consumption had low risk of IFG/DM (OR=0.57, 95%CI= 0.43-0.77) than those who consumed 1-2 times/week. Students without eating out habit had lower risk of hypercholesteremia /hypertriglyceridemia than those with eating out for 1-2 times/week (OR=0.78, 95%CI=0.62-0.98), and students who had lunch out of home or canteen had higher risk of hypercholesteremia /hypertriglyceridemia than those who ate at canteen (OR=1.38，95%CI=1.06-1.81). Conclusion The prevalence of metabolic disorder among high school students in Guangzhou is at a relatively high level. High eating speed, heavy sugared beverages intake and frequently eating out habits are associated with risk of metabolic disorder.

Objective: To evaluate the influence of happiness therapy intervention on the medication compliance and quality of life of acquired immune deficiency syndrome (AIDS) patients after discharge. Methods: A total of 106 adult AIDS patients discharged from hospital from July 2016 to July 2017 were randomly divided into control group (52 cases), observation group (54 cases). The control group was given routine health education and instruction, and three times of happiness therapy intervention were performed during the hospitalization. The observation group increased the number of happiness therapy intervention after discharge according to the patient′s medication compliance. The medication compliance scale and quality of life scale were used to evaluate the compliance rate and quality of life of patients in 2 groups at discharge, 3 months after discharge, 6 months after discharge, and 12 months after discharge. Results: There was no significant difference in medication compliance and quality of life at discharge and 3 months after discharge between the two groups (P>0.05). At 6 months and 12 months after discharge, the compliance rate and quality of life scores in the observation group was 90.74%(49/54), 88.89%(46/54) and (69.62 ± 5.82) points, (68.76 ± 5.63) points, respectively, 61.54% (32/52), 59.62% (31/52) and (52.12 ± 4.30) points, (52.05 ± 4.25) points in the control group, the difference was statistically significant (χ²=9.684, 9.035, t=8.638, 8.963, P<0.01). Conclusions The happiness therapy intervention during hospitalization can effectively improve the medication compliance and quality of life of AIDS patients. After the discharge, the happiness therapy intervention can provide the patients with long-term nursing programs, which can improve the adherence and quality of life of AIDS patients compared with the control group Have a better long-term effect.

Objective: To understand the situation of school medical staff in Guangzhou after adopting multichannel medical model, and to provide reference for school medical team construction. Methods: A total of 1 099 primary and secondary schools in Guangzhou participated in this study through questionnaire survey regarding school medical personnel, basic situation of school medical personnel and work situation. Results: Among the 1 099 primary and secondary schools surveyed, 638(58.05%) of them consisted of 707 full-time school doctors, the eligible rate was 28.20%. The recruitment of school doctors was still based on independent recruitment(55.87%), and 44.13% of the purchase service modes (community deployment, hospital purchase services, and school clinic custody) were deployed. Most of school medical professionals majored in nursing(56.86%), followed by clinical medicine (26.03%) and preventive medicine (9.76%); In terms of professional titles, junior, intermediate and senior certificates accounted for 52.47%, 37.34%, and 1.27%, respectively; More than 68.74% of school doctors worked for less than 5 years; On average, 68.60% of training were provided every six months. About 33.95% of the school doctor were satisfied with salary, 20.79% were not satisfied. Compared with the year 2016, no significant changes were noticed in academic qualifications, professional titles, and working conditions of school medical team, however, increased proportion of staffs with nursing certificate instead of clinical medicine certificate increased, workload and satisfaction towards salary decreased(P<0.01). Conclusion After adopting the multi-channel deployment model, the construction of school health workforce in Guangzhou has made breakthrough progress. It is proposed to improve the guidelines for the standardization of school doctors, to strengthen the professional skills training of school doctors, and to better improve the overall level of school health work in the city.

Immunoscenescence plays a key role in the initiation and development of tumors. Furthermore, immunoscenescence also impacts drug delivery and cancer therapeutic efficacy. To reduce the impact of immunosenescence on anti-tumor therapy, this experimental plan aimed to use neutrophils with tumor tropism properties to deliver sialic acid (SA)-modified liposomes into the tumor, kill tumor cells via SA-mediated photochemotherapy, enhance infiltration of neutrophils into the tumor, induce immunogenic death of tumor cells with chemotherapy, enhance infiltration of CD8⁺ T cells into the tumor-draining lymph nodes and tumors of immunosenescent mice, and achieve SA-mediated photochemotherapy. We found that CD8⁺ T cell and neutrophil levels in 16-month-old mice were significantly lower than those in 2- and 8-month-old mice; 16-month-old mice exhibited immunosenescence. The anti-tumor efficacy of SA-mediated non-photochemotherapy declined in 16-month-old mice, and tumors recurred after scabbing. SA-mediated photochemotherapy enhanced tumor infiltration by CD8⁺ T cells and neutrophils, induced crusting and regression of tumors in 8-month-old mice, inhibited metastasis and recurrence of tumors and eliminated the immunosenescence-induced decline in antitumor therapeutic efficacy in 16-month-old mice via the light-heat-chemical-immunity conversion.
