Objective:To explore the clinical value of PUFA in the treatment of cancer cachexia,meta-analysis and systematic evaluation of literature was applied.Methods:According to the inclusion criteria,PubMed/MEDLINE,EMBASE and the Cochrane Central Register of Controlled TriMs for randomized controlled trims that compared PUFA treatments with placebo or no treatment in cancer cachexia were searched.Outcomes of interest were effects on weight,appetite,the level of CRP and IL-6,the composition of lean body mass and the quality of life.Results:Finally,16 articles were included in the analysis,which reported appetite (6 papers),C-reactive protein (9 papers),IL-6 (5 papers),lean tissue weight (7 papers) and quality of life assessment (7 papers),respectively.Conclusion:PUFAs for the treatment of cancer cachexia plays an irreplaceable role.The body weight,appetite,inflammation index and quality of life can be significantly improved,and the patients can tolerated the addition of PUFA during the treatment.

Objective: To establish C57BL/6 transgenic mice lineages containing pMTR1 plasmids as an efficient animal model for studying gene mutation in vivo . Methods: The linearized pMTR1 DNAs, constructed by molecular cloning, were injected into 572 fertilized eggs of C57BL/6 mice by microinjection. The manipulated embryos were transferred into the oviducts of 45 pseudopregnant mice respectively, from which 35 offsprings were obtained. The genomic DNAs of these offsprings were analyzed with PCR and genomic Southern blotting. Four mice whose genomes integrated with copies of intact pMTR1 vectors were chosen as founders to establish transgenic mice lineages. The recovery of pMTR1 plasmid were conducted on the genomic DNAs of F1 or F2 transgenic offsprings. Results: It was showed that intact and functional pMTR1 plasmid could be efficiently recovered from the genomic DNAs of these mice. Conclusion: (1) The transgenic mouse lineages containing copies of a stably integrated pMTR1 plasmid is established. (2) The transgenic mice are suitable models for studying gene mutation in vivo .

To study the protective effects of salidroside on oxidative damage in fatigue mice.

AIM To determine the contents of arillanin A,tenuifoliside A and tenuifoliside C in raw Polygalae Radix (root barks),Polygalae Radix duramen,Glycyrrhizae Radix et Rhizoma-processed Polygalae Radix,waterboiling Polygalae Radix and honey-processed Polygalae Radix.METHODS The analyses of 50％ methanol extracts from samples were performed on a 30 ℃ thermostatic Kromasil C18 column (250 mm ×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-0.1％ formic acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 330 nm.RESULTS The contents of three oligosaccharide esters were the highest in raw Polygalae Radix,followed by those in honey-processed Polygalae Radix,and those in water-boiling Polygalae Radix were the lowest.These constituents also existed in Polygalae Radix duramen,but their contents were lower than those in root barks.CONCLUSION The ester bonds of oligosaccharide esters in Polygalae Radix may be hydrolyzed during processing,followed by the generation of small molecular organic acids.The medication of whole Polygalae Radix (root barks and duramen) can be taken into consideration in clinical practice to reduce toxicity and enhance efficacy.

Objective:To construct an inter-hospital standardized transport scheme for patients supported by extracorporeal membrane oxygenation (ECMO) combined with modified early warning score (MEWS) and the transport checklist based on the theory of process reengineering.Methods:Through literature review, according to the actual situation of the Second Affiliated Hospital of Zhengzhou University, the MEWS scores and transport verification sheets were effectively combined to construct the inter-hospital standardized transport scheme for patients supported by extracorporeal membrane oxygenation. And according to the inter-hospital standardized transport scheme, the medical staff in the transport team were trained and assessed for ECMO patient transport knowledge. Using the convenient sampling method, a total of 223 ECMO patients admitted to the Second Affiliated Hospital of Zhengzhou University from January to December 2019 who were transported by conventional transport were selected as the control group. A total of 222 ECMO patients who were transported by the ECMO interhospital standardized transport scheme from January to December 2020 were selected as the observation group. This study Compared the incidence of adverse transport events in the two groups of and the transport knowledge of medical staff in the transport group before and after training.Results:The score of transport knowledge of ECMO patients of medical staff after training were higher than those before training, and the difference was statistically significant ( P<0.01) . The incidence of transport adverse events in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:The standardized inter-hospital transport scheme for ECMO patients can form an efficient and safe standardized transport process, reduce the incidence of adverse transport events and improve the transport safety of ECMO patients.
