Chinese Journal of Clinical Nutrition 2010;18(5):276-278
Objective To investigate the causes of nutritional risks among inpatients in middle and small hospitals in Guangxi Zhuang Autonomous Region of China. Methods All the screened subjects were surveyed through classified collection of medical records and telephone follow-up. Factors including education background of patients and their family members, career, income, residence, medical payment methods, grade of hospital, and awareness of nutrition were analyzed. Results Lower education background of patients and their family members,less income, and self-funded health care payment were significantly associated with higher nutritional risks ( P <0. 01 ). The scores of malnutrition risks were significantly lower in patients whose careers were involved with culture, education and health and in patients whose family members had higher education levels (P < 0.01 ). The nutrition risk was also significantly higher in patients from the rural areas than those from urban areas ( P<0.01 ). It was also significantly higher in middle and small hospitals than in tertiary hospitals ( P<0.01). Patients who had good awareness of nutritional knowledge had significantly lower incidence of nutritional risk (P < 0. 01 ). Conclusion Low education level and poor economy in Guangxi are the main reasons for high nutritional risks.

China Pharmacy 2015;(22):3103-3105
OBJECTIVE:To study the induction effect of paeoniflorin on the apoptosis of lung adenocarcinoma A549 cells. METHODS:MTT method was used to detect the viability of A549 cells 48 h after the cells were cultured with paeoniflorin of 0 (negative control),5,10,20 and 40μmol/L. 24 h after A549 cells were cultured with paeoniflorin at the above-mentioned concen-trations,enzyme-linked immunosorbent assay was employed to detect the viability of cysteinyl aspartate specific proteinase 3(Cas-pase-3),and Western blot to determine the protein expression of Bcl-xl,Bax,nuclear factor κB p65(NF-κB p65)and phosphory-lated nuclear factorκB p65(NF-κB pp65). RESULTS:Compared to the negative control group,A549 cells cultured with paeoniflo-rin of 5-40 μmol/L for 48 h showed lower cell viability;A549 cell cultured with paeoniflorin of 5-40 μmol/L for 24 h showed high-er activity of Caspase-3 and the expression of Bax;A549 cell cultured with paeoniflorin of 10-40 μmol/L for 24 h showed lower protein expression of Bcl-xl and NF-κB pp65. There were statistically difference(P<0.01 or P<0.05). CONCLUSIONS:Paeoni-florin induces the apoptosis of A549 cells by a mechanism which may be related to the activation of NF-κB signaling pathway and regulation related gene expression.

4.Evaluation and Intervention for Frailty in Old Adults (review)
Chinese Journal of Rehabilitation Theory and Practice 2015;(11):1282-1286
Frailty is a pre-disabled stage and associated with increased vulnerability to adverse health outcomes. Frailty has high preva-lence in older population. There are 2 principal emerging models of frailty, which are the phenotype model and the frailty index model. Many studies have developed tools to detect frailty, including self-report scales, such as PRISMA-7, Groningen Frailty Indicator (GFI), Ed-monton Frail Scale (EFS) and Simple Frailty Questionnaire (FRAIL);and single assessments, such as gait speed, timed up-and-go test, grip strength, pulmonary function test. Intervention of exercise and/or nutrition are benefical for frail older adults.

The endoplasmic reticulum (ER) serves several important functions, mainly post-translational modification, folding and assembly of newly synthesized secretary proteins, synthesizing lipids and cellular calcium storage. Various factors can disrupt ER homeostasis and disturb its functions, which leads to the accumulation of unfolded and misfolded proteins and to potential cellular dysfunction and pathological consequences, collectively termed ER stress. Recent progress suggests that ER stress plays a key role in the immune response, diabetes, tumor growth, and some neurodegenerative diseases. In particular, ER stress is involved in several processes of cardiovascular diseases, such as ischemia/reperfusion injury, cardiomyopathy, cardiac hypertrophy, heart failure, and atherosclerosis. Further research on the relation of ER stress to cardiovascular diseases will greatly enhance the understanding of these pathological processes and provide novel avenues to potential therapies.
