Objective To compare the influences of different routes of nutrition on the outcome and respiratory muscle strength of elderly patients in respiratory intensive care unit (RICU). Methods Totally 147 elderly patients in RICU were equally randomized into combined nutrition group ( combinination of parenteral nutrition and enteral nutrition), total enteral nutrition (EN) group, and total parenteral nutrition (PN) group. The changes of energy metabolism, respiratory muscle strength, and short-term outcome were observed or determined.Results Plasma albumin (ALB), hemoglobin (Hb), creatinine (Cr) levels, and nitrogen balance significantly increased in all group 7 days later ( all P < 0. 01 ), while blood urea nitrogen (BUN) significantly decreased ( P <0.01 ). The increase of ALB, Hb, Cr levels, and nitrogen balance were significantly more remarkable than that in EN group and PN group (P<0.05 or P<0.01). The decrease of BUN level in the combined nutrition group was significantly more remarkable than that in EN group ( P < 0. 05 ). After nutritional support, the maximum inspiratory pressure in the combined nutrition group (P =0. 021 ) and EN group (P = 0. 011 ) became significantly higher, and occlusion pressure at 0.1 second inspiration level in the combined nutrition group became significantly lower ( P =0. 025). The incidences of infectious and non-infectious complications in PN group were significantly higher than those in EN group (P = 0. 002 and 0. 017, respectively) and combined nutrition group ( P = 0. 005 and 0. 004, respectively). Gastric retention was more common in EN group than that in PN group ( P = 0. 035). The weaning time,length of RICU stay, length of hospital stay and 20-day-mortality were significantly decreased in the combined nutrition group than those in the other two groups ( all P < 0. 05 ). Conclusion The effectiveness of the combined application of PN and EN is superior to PN or EN alone in improving nutritional status and respiratory muscle strength as well as in improving the short-term outcome in elderly patients in RICU..

More and more attention has been drawn on nano-materials in the application of molecular imaging and targeted cancer therapy. Quantum dots, due to their rich surface chemical properties and bright stable fluorescence, have been used as a new type of nano-probes and widely used in molecular, cellular and vivo biological imaging. In recent years, many inspiring achievements have been obtained in the study on quantum dots surface modification and biological imaging in cell and animals. In this article, current status and the latest developments of the study and the application are reviewed.

In this study, a combination of metabolomics and network pharmacology was used to study the pharmacodynamic substances and mechanism of action of Yiyi Fuzi powder (YYFZ) on rheumatoid arthritis (RA) rats. The animal experiments were conducted in accordance with the requirements of the Experimental Animal Ethics Committee of Tianjin University of Traditional Chinese Medicine (approval number: TCM-LAEC2021241). The metabolomic analysis using UPLC-Q-TOF/MS technique identified 22 metabolites, including arachidonic acid, tryptophan, linoleic acid, phenylalanine, as significant biomarkers for the treatment of RA with YYFZ, and they were significantly regressed after YYFZ treatment. The analysis of YYFZ blood components also revealed that 11 blood components, including hypaconitine, benzoylhypaconitine, and deoxyaconitine, may be the components that exert direct pharmacological effects in YYFZ

Objective To investigate the approach of diagnosis and therapy of particular tracheal bronchus foreign body.Methods The clinical materials of 26 cases cured in our department were analyzed retrospectively.Results All foreign bodies of cases were taken out successfully.Among them,the foreign bodies of 18 cases were removed from glottis;the foreign bodies of 4 cases were pulled out via laryngoscope;the foreign bodies of 3 cases were drawn away through tracheotomy by endoscopy and 1 case was moved out by bronchofibroscopy.Only 1 case had lung edema and then was cured by proper treatment.Conclusion Considering that the particular foreign bodies in tracheal bronchus are complicated sometimes,the diagnosis and therapy should be treated appropriately according to different situation.Furthermore,properly choosing surgical appliances and the approaches of anaesthesia and surgery is also critical.
