Objective:
To explore the effects of multidisciplinary team based nursing intervention on nutritional status, muscle strength, physical function and daily living ability of super-aged patients with sarcopenia.
Methods:
A total of 29 super-aged patients with sarcopenia from July to November in 2017 in Department of Geriatric, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School were selected as the observation group with multidisciplinary team intervention. And 29 super-aged patients with sarcopenia from February to June 2017 were selected as the control group with routine management. Nutritional indicators, muscle strength, physical activity function and daily living ability scores were compared between the two groups at 1 and 6 months after intervention.
Results:
After 1 month of intervention, hemoglobin and serum albumin was (118.79±11.47), (35.86±5.73) g/Lin the observation group and (112.27±11.69), (31.35±5.48) g/L in the control group, the difference between the two groups was statistically significant (

Objective To analyze and identify the volatile constituents in different parts(flowers,stems and leaves)of Huai chrysanthemumin,and to lay a theoretical foundation for the comprehensive utilization for it.Methods The volatile oil in different parts of Huai chrysanthemumin were extracted by hydrodistillation,respectively.Their constituents were analyzed by gas chromatography-mass spectrometry(GC-MS).The compounds were identified by library search and literature screening.The relative percentage of each compound was obtained by the area normalization method.The differences in their chemical compositions were analyzed by Venn diagram,principal component analysis(PCA)and cluster heat map analysis.Results A total of 62 volatile chemical components were identified from different parts of Huai chrysanthemumin,including monoterpenes,sesquiterpenes,and their derivatives,as well as a small amount of aliphatic compounds.32,42 and 40 volatile components were detected from the flowers,stems and flowers,respectively.Furthermore 17 volatile components were shared by three parts,whereas 5,6 and 16 volatile components were unique to the flowers,stems and leaves,respectively.The results of stoichiometric analysis showed that both PCA and cluster heat map analysis could separate the flowers,stems and leaves,and their volatile components were different.Conclusion The types and contents of the volatile oil in the stems,leaves and flowers of Huai chrysanthemumin have certain variability,which provide a scientific basis for the further medicinal or industrial exploitation of different parts of Huai chrysanthemumin.

OBJECTIVE:
To explore the expression of the RNA-binding protein tristetraprolin in lung adenocarcinoma cells and its molecular mechanism for inhibiting autophagy.
METHODS:
Quantitative real-time PCR and Western blotting were performed to detect the expression of autophagy-related genes (including Beclin1, LC3-Ⅱ/LC3-Ⅰ and SQSTM1/p62) in cultured lung adenocarcinoma cells at 24, 48 and 72 h after transient transfection with a tristetraprolin-overexpressing plasmid and the empty plasmid. The effects of transfection with the tristetraprolin-overexpressing plasmid and empty plasmids in the presence or absence of tumor necrosis factor- (TNF-) on the expressions of nuclear factor-κB (NF-κB) p65, c-rel, and p50 were examined in lung adenocarcinoma cells using immunofluorescence assay and Western blotting. The cells were also transfected with the IκBα-mut plasmid and the tristetraprolin-overexpressing plasmid, either alone or in combination, and the changes in the expressions of tristetraprolin and autophagy-related genes were detected using RT-qPCR and Western blotting.
RESULTS:
The expressions of tristetraprolin were significantly reduced at both the mRNA and protein levels in lung adenocarcinoma cells ( < 0.001). Overexpression of tristetraprolin in the cells significantly lowered the expressions of autophagy-related genes Beclin1 and the ratio of LC3-Ⅱ/LC3-Ⅰ at the mRNA and protein levels ( < 0.001), obviously lowered the expressions of NF-κB p65 and c-rel, and almost totally blocked the nuclear translocation of NF-κB p65 and c-rel ( < 0.05); the expression of p50, however, did not undergo significant changes in response to tristetraprolin overexpression ( > 0.05). The inhibitory effect of tristetraprolin overexpression on autophagy was abrogated by transfection of the cells with IκBα-mut plasmid, which blocked the NF-κB signaling pathway. Co-transfection of the cells with IκBα-mut also attenuated the inhibitory effect of tristetraprolin overexpression on Beclin1 and the LC3-Ⅱ/LC3-Ⅰ ratio at both the mRNA and protein levels ( < 0.05).
CONCLUSIONS
The expression of tristetraprolin is low in lung adenocarcinoma cells. Tristetraprolin overexpression causes inhibition of autophagy in lung adenocarcinoma cells possibly by blocking NF-κB p65 and c-rel nuclear translocation.

OBJECTIVE To co mpare the difference of liposoluble constitue nts in different processed products of Huaizhong No.1 Rehmannia glutionsa (fresh R. glutionsa ,R. glutionsa and prepared R. glutionsa ),and to evaluate its in vitro antioxidant activity preliminarily. METHODS Liposoluble extracts were extracted from 3 processed products of R. glutionsa by Soxhlet extraction. Their constituents were analyzed by gas chromatography-mass spectrometry. The spectral library of NIST 98 system was used to automatically retrieve the mass spectrum information of components ,and the structures of compounds were identified in combination with relevant literature and by comparing with eight peak index and EPA/NIH library. Relative contents of the components were calculated by using peak area normalization method with Hewlett Packard software. The antioxidant activities of liposoluble constituents in 3 processed products of R. glutionsa were investigated by 1,1-diphenyl-2-picrylhydrazyl(DPPH)free radical scavenging. RESULTS A total of 79 liposoluble components were identified from different processed products of R. glutionsa,and 48,52 and 37 liposoluble compounds were identified from fresh R. glutionsa ,R. glutionsa and prepared R. glutionsa,respectively;their relative contents accounted for 92.69%,86.29%,92.89% of the total components respectively. Among them ,there were 20 liposoluble compounds totally ,and their relative contents accounted for 88.73%,80.89% and 85.87% of liposoluble components in each processed product respectively ;they were mainly composed of fatty acids such as methyl linoleate,methyl palmitate and methyl oleate. In addition ,there were 18 unique liposoluble components in fresh R. glutionsa , mostly terpenoids ;there were 17 and 6 unique liposoluble components in R. glutionsa and prepared R. glutionsa ,mostly alkanes. The results of antioxidant experiment showed that median scavenging concentrations of liposoluble components to DPPH limeng free radical were 0.756,0.660,0.758 mg/mL,respectively. CONCLUSIONS The common liposoluble components in different processed products of R. glutionsa are mostly acids;the unique liposoluble components in fresh R. glutionsa are mostly terpenoids ,and those of R. glutionsa and prepared R. glutionsa are mostly alkanes ;the liposoluble constituents possess in vitro antioxidant activities.
