Objective To compare the difference between GUSS swallowing evaluation and traditional evaluation as a symbol of pulling out stomach tube.Methods 60 patients with cerebral hemorrhage combined with indwelling tube were divided into two groups,the GUSS group and the traditional group,according to the symbol of pulling out the gastric tube.Each group contained 30 cases.The GUSS score ≥ 15 points was used as the symbol of pulling out the gastric tube in the GUSS group,while being able to eat 200 ml liquid without any trouble in two days was used as the symbol in the traditional group.Then we compared the incidence of gastric tube reinsertion and aspiration pneumonitis between the two groups.Results No gastric tube reinsertion and aspiration pneumonitis occurred in the GUSS group,while 7 cases accepted gastric tube reinsertion and 3 cases diagnosed as aspiration pneumonitis in the traditional group.The incidence of gastric tube reinsertion and aspiration pneumonitis in the GUSS group were obviously lower than those in the traditional group.Conclusions GUSS evaluation score ≥ 15 points could be used as a symbol of pulling out gastric tube.

Objective To analyze the clinical features and risk factors for mortality of patients with severe fever with thrombocytopenia syndrome (SFTS) in Zhoushan, the eastern coastal of China with high incidence of severe fever with thrambocytopenia syndrome bunyavirus infection, to provide reference for reducing the mortality rate of SFTS.Methods Clinical data of 107 cases of SFTS from Zhoushan Hospital during June 2011 to June 2016 were retrospectively analyzed.According to the prognosis, patients were divided into survival group and death group.The clinical features and the laboratory results were analyzed with a case-control method to analyze the prognostic factors.Normal distribution data were compared with the independent t test.Kolmogorov-Smirnov Z test were used in data with skewness distribution.Categorical data were analyze by chi-square test.The related risk factors were analyzed with the receiver-operating characteristic (ROC) curve and multivariate unconditioned logistics regression analysis.Results Seventeen cases among 107 STFs patients died, yielding the mortality rate of 15.9%.The proportion of patients suffering from two or more underlying diseases, with disorders of consciousness, activated partial thromboplastin time (APTT), the level of creatine kinase (CK), lactate dehydrogenase (LDH) as well as sepsis-related or sequential organ failure assessment (SOFA) score in death group were all significantly higher than those in the survival group (all P<0.05).The Ca2+ level and fibrinogen level in death group were significantly lower than those in the survival group (both P<0.05).Indexes mentioned above were analyzed by ROC curve, and the calculated cut-off value was set as the optimal diagnostic thresholds.These data were then included into the multivariate logistic regression analysis.It turned out that Ca2+<1.625 mmol/L, APTT >73.45 s, SOFA scores >9 were the independent risk factors for mortality of SFTS (OR=6.947, 8.459 and 11.770, respectively, all P<0.05).Conclusion Ca2+, APTT and SOFA score are the independent risk factors for prognosis of SFTS, which provide reference for prognostic evaluation of SFTS.

Objective To explore the risk factors of dysphagia in the patients with traumatic brain injuries (TBI). Methods 141 TBI patients were assessed with Gugging Swallowing Screen, and divided into the dysphagia (n=36) and normal (n=105) groups. The related factors were compared between 2 groups. Results The frequency increased in severe brain injury, brain stem injury, bilateral brain injury, tracheotomy, nasal-gastric tube insertion and cognitive defect in the dysphagia group compared with those in the normal group (P<0.05). Conclusion The severe brain injury, brain stem injury, bilateral brain injury, tracheotomy, nasal-gastric tube insertion and cognitive defect may be related with the dysphagia post TBI.

Objective To investigate the clinical validity of the Chinese version of John Hopkins Adapted Cognitive Exam (ACE) for in-patients in neurological intensive care unit (NICU). Methods From May, 2014 to June, 2015, 94 inpatients in NICU and 52 healthy persons were assessed with the Chinese version of ACE and Mini-Mental State Examination (MMSE). Results The total score of ACE correlated with the total score of MMSE (r=0.805, P<0.001). There was a significant difference in the total score and the scores of the subtests of both the ACE and MMSE between the patients and the controls (t>2.458, P<0.05). The area under the receiver operating curve was not different between ACE and MMSE (Z=0.707, P=0.480). Conclusion The Chinese version of ACE can be the tool for assessment of cognition for pa-tients in NICU.

To investigate the effects of genistein (Gen) on the biosynthesis of N-glycolylneuraminic acid (Neu5Gc) in rats, 80 4-week-old male SD rats were randomly equally into the control and genistein groups. The rats of control and genistein groups were fed 5% ethanol and 300 mg/(kg·d) genistein respectively by gavage. The contents of Neu5Gc in hind leg muscle, kidney and liver tissues of rats were measured by using high performance liquid chromatography coupled with fluorescence detector (HPLC/FLD), and the mechanism of inhibition of Neu5Gc synthesis was investigated by using the molecular docking of Gen and sialyltransferase. On the 15th day, the content of Neu5Gc in hind leg muscle and liver tissues decreased 13.77% and 15.45%, respectively, and there was no significant change in the content of Neu5Gc in kidney tissues. On the 30th day, the content of Neu5Gc in liver tissues decreased 13.35%, however, there was no significant change in the content of Neu5Gc in kidney tissues and Neu5Gc was not detected in hind leg muscle. The content of Neu5Gc in hind leg muscle, kidney and liver tissues decreased respectively 32.65%, 32.78%, 16.80% and 12.72%, 11.42%, 12.30% while rats fed on the 45th and the 60th days. Genistein has formed the hydrogen bond with sialyltransferase activity site residues His319, Ser151, Gly293, Thr328 and formed a hydrophobic interactions with the residues His302, His301, Trp300, Ser271, Phe292, Thr328, Ser325 and Ile274. The results of molecular docking indicated that the weak intermolecular interaction was the main cause of genistein inhibiting sialyltransferase activity. The research results provided an experimental basis for the subsequent reduction of Neu5Gc in red meat before slaughter.
