AIM: To investigate whether illness severity has an impact on gastric residual volume (GRV) in medical critically ill patients. METHODS: Medical intensive care unit (ICU) patients requiring nasogastric feeding were enrolled. Sequential Organ Failure Assessment (SOFA) score was assessed immediately preceding the start of the study. Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ scores were recorded on the first, fourth, seventh, and fourteenth day of the study period. GRV was measured every 4 h during enteral feeding. The relationship be-tween mean daily GRV and SOFA scores and the correlation between mean daily GRV and mean APACHE Ⅱ score of all patients were evaluated and compared. RESULTS: Of the 61 patients, 43 patients were survivors and 18 patients were non-survivors. The mean daily GRV increased as SOFA scores increased (P < 0.001, analysis of variance). Mean APACHE Ⅱ scores of all patients correlated with mean daily GRV (P = 0.011, Pearson correlation) during the study period. Patients with decreasing GRV in the first 2 d had better survival than patients without decreasing GRV (P = 0.017, log rank test). CONCLUSION: GRV is higher in more severely ill medical ICU patients. Patients with decreasing GRV had lower ICU mortality than patients without decreasing GRV.

Malnutrition has been recognized as a significant risk factor for the post operated patients, especially for those patients undergoing abdominal operations. This study evaluated the effect of hypo-calories with micronutrients of pre-operative peripheral parenteral nutrition support (PPPN) for rectal cancer patients. Retrospective cross sectional study method was used to investigate. We screened rectal cancer patients past year pre-operative with malnutrition risk from our cancer database and divided into 2 groups, received or not received PPPN and compared the post-operative outcomes. The results showed that the post-operative serum albumin of the 25 patients received PPPN averaged 2.5 ± 0.32 g/dl;significantly better than those of the 15 patients not received PPPN (non-PPPN), which averaged 1.92 ± 0.42 g/dl. The first ambulatory time required 3.0 ± 0.8 days for the PPPN, significantly shorter than those for the non-PPPN, which averaged 4.9 ± 2.4 days. Post-operative hospital days for the patients received PPPN were 18.2 ± 10.5 day, also significantly fewer than the non-PPPN, which averaged 33.7 ± 20.0 day. More than 25% of the non-PPPN was infected with sepsis, while none was infected in the PPPN patients. In conclusion, this study verified the benefits of micronutrients of pre-operative peripheral parenteral nutrition support for rectal cancer patients.

The counterion-mediated hydrogen bonding(CMHB)is related to the hydrogen bonding between bound counterions and polyelectrolyte chains in polyelectrolyte systems,where the counterions can both electrostatically bind to the charged groups of polyelectrolyte chains and act as hydrogen bond donors or acceptors to form hydrogen bonds with the hydrogen bond sites associated with polyelectrolyte chains simultaneously.A large number of literatures illustrate that strong polyelectrolytes(SPs)are insensitive to pH,which severely limmits the applications of SPs as smart ***,our studies have demonstrated that the CMHB makes SPs *** perspective discusses the mechanism of pH responsiveness of SPs and the pH-tunable properties of SPs,based on the pH-controlled CMHB *** future research directions on the pH responsiveness of SPs are also discussed *** is anticipated that the study of the pH responsiveness of SPs not only will provide a new understanding of the fundamental properties of SPs,but also will greatly expand the applications of SPs in the field of smart materials.
