Objective:To explore the feasibility of bedside ultrasound in monitoring gastric residual volume and predicting feeding intolerance during enteral nutrition in critically ill patients in intensive care unit.Methods:The data of critically ill patients admitted to emergency intensive care unit of the Second Affiliated Hospital of Zhejiang University School of Medicine from April 2018 to September 2018 were retrospectively analyzed. The following patients were finally included in this study: (1) abdominal computed tomography during the stay of emergency intensive care unit was performed due to the requirement of disease evaluation and management; (2) bedside ultrasound was performed to measure the gastric antrum cross-sectional area at 30 min prior to or after abdominal computed tomography. The outline of stomach wall in the imaging of abdominal computed tomography was traced with the help of VOLUME-Work Flow medical imaging software to calculate the value of gastric residual volume. The relationship between gastric antrum cross-sectional area under semi-sitting, horizontal and right-lateral positions and gastric residual volume was evaluated by Pearson correlation analysis. The difference of gastric antrum cross-sectional area between those critically ill patients with or without feeding intolerance was compared by independent-sample t test. The predictive value of gastric antrum cross-sectional area under different body positions on feeding intolerance during enteral nutrition was analyzed by ROC curve. Results:Totally, forty-two patients were enrolled and analyzed in this study, in which the mean age was (53±13) y, mean body mass index was (21.5±2.8) kg/m 2 and mean acute physiology and chronic health evaluation was 17.0±6.9. The value of gastric residual volume was (314.5±126.6) mL, and the values of gastric antrum cross-sectional area under semi-sitting, horizontal and right-lateral positions were (7.11±4.13) cm 2, (4.22±2.66) cm 2, (8.36±4.58) cm 2, respectively. The correlation analysis indicated that gastric residual volume was positively associated with gastric antrum cross-sectional area under semi-sitting, horizontal and right-lateral positions ( r=0.543, 0.604 and 0.618, respectively; all P<0.001). During enteral nutrition, 15 patients experienced feeding intolerance while 27 patients hadn’t feeding intolerance, in which the gastric antrum cross-sectional areas under semi-sitting, horizontal and right-lateral positions were significantly increased in those patients with feeding intolerance than those patients without feeding intolerance [semi-sitting: (8.53±4.07) cm 2vs (4.60±2.76) cm 2; horizontal position: (5.15±2.75) cm 2vs (2.61±1.32) cm 2; right-lateral position: (10.32±4.06) cm 2vs (4.95±3.20) cm 2, all P<0.005] . ROC curve analysis showed that the area under ROC curves of gastric antrum cross-sectional area under semi-sitting, horizontal and right-lateral positions for predicting feeding intolerance during enteral nutrition were 0.815, 0.833 and 0.849, respectively; when its values≥3.917 cm 2, 3.395 cm 2 and 4.402 cm 2 were used as the cut-off points, the sensitivities were 92.0%, 69.6% and 92.3%, and the corresponding specificities were 69.2%, 92.3% and 71.4%, respectively. Conclusions:Bedside gastric ultrasound could accurately evaluate the status of gastric residual volume in critically ill patients, and effectively predict their occurrence of feeding intolerance during enteral nutrition.

OBJECTIVETo explore the repair effects of acupuncture for promoting the governor vessel and tranquilizing the mind (acupuncture technique) on cerebral white matter injury of premature infants.
METHODSA total of 56 cases of cerebral whiter matter injury of premature infants, the fetal age less than 35 weeks were selected and randomized into an observation group (27 cases) and a control group (29 cases). The routine basic rehabilitation therapy was used in the two groups. Additionally, in the observation group, the acupuncture technique was added, once a day and the treatment for 15 days was as 1 course. Totally, 3 courses of treatment were required. Before and after treatment, the cranial magnetic resonance imaging (MRI) and the diffusion tensor imaging (DTI) were adopted to observe the location and severity of cerebral white matter injury. The Gesell developmental scale was used to assess the nerve motor development.
RESULTSAfter treatment, the difference was not significant statistically in the severity of cerebral white matter injury in the infants between the two groups (>0.05). The FA value of cerebral white matter in the interesting zone was increased as compared with that before treatment in the infants of the two groups (both<0.05). The result in the observation group was higher than that in the control groups (<0.05). After treatment, DQ value of each function zone in Gesell scale was all increased as compared with that before treatment in the two groups (all<0.05). After treatment, the DQ values of gross motor, fine motor and social adaptability in the observation group were higher than those in the control group (all<0.05). After treatment, the difference was not significant in DQ value of individual-social and speech behaviors between the two groups (both>0.05).
CONCLUSIONAcupuncture technique for promoting the governor vessel and tranquilizing the mind promotes the repair of the function in the premature infants with cerebral white matter injury and further benefits the promotion of the intelligence.
4. Research progress in innate immune mechanisms during influenza A virus infection
Chinese Journal of Experimental and Clinical Virology 2017;31(3):277-280
Influenza A virus is an enveloped virus of the Orthomyxoviridae family. Acute fever, generalized pain, fatigue and respiratory symptoms are the typical symptoms after influenza A virus infection. Influenza A virus triggers the activation of signaling pathways that are dependent on host pattern recognition receptors (PRRs) including toll-like receptors (TLRs), retinoic acid-inducible gene I receptors (RLRs) and NLRs. Then these signaling pathways activate downstream transcript factors that induce expression of various interferons and cytokines (IL-1, IL-18). This review will elaborate the mechanisms of these PRRs.

BACKGROUND:Stem cel s with wide variety of sources have the potential of differentiation and self-renewal. In additional, autologous stem cel s can avoid immune rejection after transplantation, and thus it has become one of the most promising alternative strategies for tissue/organ transplantation. However, due to the adverse environments at injured sites, such as oxidative stress and inflammation, current stem cel transplantation efficacy is relatively low. OBJECTIVE:To review the effects of oxidative stress on stem cel s and on their transplantation efficiency as wel as relevant mechanisms. METHODS:PubMed database was searched by the first author for relevant articles about stem cel s published from 1990 to 2015. The keywords were“stem cel transplantation, stem cel , oxidative stress, molecular mechanism”. After eliminating literatures which had poor authority or similar content, 97 articles were involved in result analysis. RESULTS AND CONCLUSION:Different types of stem cel s have different basal endogenous antioxidant stress levels. Oxidative stress through multiple molecular pathways causes cel aging, apoptosis and cancer, which also can result in apoptosis of cancer cel s. Stem cel s can adjust endogenous antioxidant levels through multiple paths. To improve the endogenous antioxidant stress level using a variety of methods can increase stem cel transplantation efficiency and prevent stem cel cancerization due to oxidative stress, which makes the clinical application of stem cel transplantation therapy safer and more popular.
