Objective To investigate the factors related with swallowing function after stroke. Methods Stroke patients with dysphagia were reviewed, 296 cases with pseudobulbar paralysis, and 82 cases with bulbar paralysis. Swallowing function was evaluated with videoflu-oroscopic swallowing study (VFSS). The variable of age, sex, Body Mass Index (BMI), scores of National Institutes of Health Stroke Scale (NIHSS), Simplified Fug-Meyer Assessment (FMA) and modified Barthel Index (MBI), intubation, aspiration, length of hospitalization (LOH), and initiation of rehabilitation intervention were analyzed with Logistic regression. Results Age, NIHSS score, intubation, aspira-tion, initiation of rehabilitation intervention were the risk factors for poor outcome of swallowing function in all the patients, while the score of MBI was the protective factor for the pseudobulbar paralysis ones. Conclusion The younger the patients, the less the NIHSS score, no in-tubation, no aspiration, and the earlier the rehabilitation intervened, the more independent the pseudobulbar paralysis patients, the better swallowing function recovered.

Objective To investigate the effect of intensive education among the families on nutritional status of the stroke patients with dysphagia. Methods 42 stroke patients with dysphagia diagnosed with Standard Swallowing Assessment were enrolled in the study. The patients and their families were randomly divided into intervention group (21 pairs) and control group (21 pairs). The families of the intervention group were given the intensive health education, 5~10 minutes each time, once a week for 1 month. The families of the control group were only given routine health education. The two groups of patients received conventional drug and swallowing function training. Hemoglobin (Hb), serum albumin (ALB), contralateral brachial triceps skin fold thickness (TSF) and arm muscle circumference (AMC) were measured 1 month latter. Results Hb, ALB, TSF and AMC in the intervention group were higher than in the control group (P<0.05). Conclusion Intensive education among the families may improve the nutritional status of stroke patients with dysphagia.

OBJECTIVE:
To construct the RNAi targeting tumor necrosis factor receptor associated factor (TRAF1) gene, and to explore the effect of interference targeting TRAF1 on the biological behavior of gastric cancer cells.
METHODS:
We detected the expression of TRAF1 in BGC823, SGC7901, and MGC803 gastric cancer cell lines through the real-time PCR and Western blot; then we constructed three pLVXshRNA- TRAF1-shRNAs expression vector targeting TRAF1. When TRAF1 was interfered successfully, we selected the strongest interference efficiency ShRNA by real-time PCR and Western blot. Based on interference targeting TRAF1 on gastric cancer, we tested the cell proliferation activity and apoptosis through MTT assay and flow cytometry, and the cell migration by transwell migration assay.
RESULTS:
The expression of TRAF1 was increased in BGC823, SGC7901, and MGC803 gastric cancer cell lines compared with gastric epithelial cells (P<0.05), and the highest expression was in BGC823 gastric cell line. In the three TRAF1 shRNAs, the strongest interference efficiency shRNA was pLVX-shRNA-TRAF1-shRNA2. When the gene TRAF1 of BGC823 was interfered, the cell growing power was weakened and the apoptosis rate increased, and the cell migration had no difference.
CONCLUSION
The expression of TRAF1 is up-regulated in gastric cancer cell lines BGC823, SGC7901, and MGC803, and the most obvious one is BGC823. The interference targeting TRAF1 can successfully inhibit the expression of TRAF1 in gastric cancer cell line BGC823. TRAF1 can inhibit the apoptosis of BGC823 cells.

Objective To evaluate the effect of dobutamine or milrinone on intraventricular syn-chronization in the patients undergoing cardiac valve replacement with cardiopulmonary bypass ( CPB). Methods Sixty American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients of both sexes, aged 40-75 yr, of New York Heart AssociationⅡorⅢ, scheduled for elective cardiac valve replacement with CPB, were divided into 3 groups (n=20 each) using a random number table: control group ( group C), dobutamine group ( group D) and milrinone group ( group M). Dobutamine 4 μg·kg-1·min-1was intravenously infused for 60 min starting from 15 min after termination of CPB in group D. Milrinone 0. 4 μg·kg-1·min-1was intravenously infused for 60 min starting from 15 min after termination of CPB in group M. The equal volume of normal saline was given instead in group C. The parameters of heart function were monitored using transesophageal echocardiography. After induction of anesthesia and before splitting the sternum (T0), at 15 min after termination of CPB (T1), and at 30 and 60 min of dobutamine, milri-none or normal saline infusion (T2, average value at two time points), the parameters of intraventricular synchronization were calculated with QLAB software (9. 1 version): standard deviation of time to peak sys-tolic velocity of the left ventricular longitudinal strain 7 segments (LVSDt-L), standard deviation of time to peak systolic velocity of the right ventricular longitudinal strain 7 segments (RVSDt), standard deviation of time to peak systolic velocity of the left ventricular circumferential strain 6 segments (LVSDt-C). Results Compared with group C, LVSDt-C, LVSDt-L and RVSDt were significantly decreased at T2in group D (P<0. 05), and no significant change was found in the indices mentioned above at each time point in group M (P>0. 05). RVSDt was significantly higher at T2in group M than in group D ( P<0. 05). Compared with the baseline at T0, LVSDt-L was significantly increased at T2in group C, and RVSDt was significantly in-creased at T2in group M ( P<0. 05). Conclusion Intravenously infusing dobutamine after CPB can im-prove the ventricular synchronization, however, intravenously infusing milrinone may increase the right ventricular asynchronization in the patients undergoing cardiac valve replacement.

Objective:To analyze the negative effect of prolonged postoperative ileus on postoperative recovery in patients underwent open alimentary tract surgery.Methods:This study was a retrospective cohort study. The subjects of the study were patients who underwent open gastrointestinal surgery at the General Surgery Department of Beijing Friendship Hospital, Capital Medical University from October 2016 to November 2018. According to the PPOI diagnostic criteria proposed by the University of Auckland, the included patients were classified as PPOI Group ( n=14) and non-PPOI group ( n=112). The postoperative complications, postoperative hospital stay and medical expenses during hospitalization were selected as the study endpoint indicators. T-test or Fisher′s exact test were performed to compare the differences between the two groups, and linear regression analysis was used to explore the independent effects of PPOI on hospital stay and medical expenses. Results:The incidence of PPOI in this study cohort was 11.1%. The total postoperative complications occurred more frequent in PPOI group (64.29% vs 38.39%, P=0.08). The average postoperative hospital stay of patients in the PPOI group was longer than that in non-PPOI group [(21.21±14.83) d vs (13.98±14.21) d, P=0.070]. Adjusting for various possible confounding factors, the PPOI regression coefficient beta (95% CI) that affects the length of hospital stay was [-0.43 (-7.16, 6.3), P=0.90]. The average medical cost of patients in the PPOI group was more than that in non-PPOI group [(104 389.64±52 427.66)元比(79 111.41±50 832.29)元, P=0.070]. Adjusting for various possible confounding factors, the PPOI regression coefficient beta (95% CI) that affects medical expenditure was [-134.12 (-21656.85, 21388.62), P=0.99]. Conclusions:Prolonged postoperative ileus leads to delayed postoperative recovery, which is related to increased postoperative complications, hospital stay duration and medical cost. But it needs further confirmation from large sample data.
