ABSTRACT
Objective:To investigate the clinical efficacy and safety of biopolysaccharide colloidal solution (Shutaishu) in the prevention of intestinal adhesion after abdominal surgery.Methods:A total of 100 patients scheduled to undergo abdominal surgery in Quzhou Municipal Hospital of Traditional Chinese Medicine from February to October in 2019 were included in this study. They were randomly divided into an observation group and a control group, with 50 patients in each group. Before closing the abdomen after surgery, abdominal cavity and wound were flashed with Shutaishu and 0.9% sodium chloride injection in the observation and control groups, respectively. The recovery of gastrointestinal function, intestinal adhesion, abdominal pain and the incidence of complications were compared between the observation and control groups.Results:The time to first regular bowel sound [(28.81 ± 5.56) h], time to first passage of flatus [(36.34 ± 6.24) h], time to first defecation [(41.65 ± 8.77) h], time taken for walking [(3.78 ± 0.64) d] in the observation group were significantly shorter than those in the control group [(32.75 ± 5.15) h, (41.51 ± 6.84) h, (48.05 ± 9.81) h, (4.27 ± 0.69) d, t = 3.68, 3.95, 3.89, 3.68, all P < 0.001]. At 5 and 30 days after surgery, the incidence of intestinal adhesion in the observation group [10.0% (5/50), 12.0% (6/50)] was significantly lower than that in the control group [26.0% (13/50), 30.0% (15/50), χ2 = 4.34, 4.88, both P < 0.05]. The total incidence of postoperative complications in the observation group was significantly lower than that in the control group [26.0% (13/50) vs. 54.0% (27/50), χ2 = 8.17, P < 0.05]. With time, visual analogue scale score was significantly decreased in both groups ( t = 3.51, 6.18, both P < 0.05). At 1, 3 and 5 days after surgery, visual analogue scale score in the observation group was significantly lower than that in the control group ( t = 4.07, 4.95 and 8.02, all P < 0.05). Conclusion:Biopolysaccharide colloidal solution is of high clinical value in the prevention of intestinal adhesion after abdominal surgery because it can promote the recovery of gastrointestinal function and early functional exercise, and has no obvious adverse reactions and complications.
ABSTRACT
ObjectiveTo investigate the mechanism of HCV infection in the pathogenesis of atherosclerosis with a model of human umbilical vein endothelial cells (HUVECs) stimulated by HCV in vitro. MethodsHUVECs were stimulated with 1.0 MOI HCVcc for 48 hours. CCK8 assay was used to measure cell proliferation; flow cytometry was used to measure cell apoptosis and cell cycle; wound healing assay and monocyte-endothelial adhesion assay were used to evaluate the influence of HCV on the migration and adhesion of HUVECs; quantitative real-time PCR and Western blot were used to measure the expression of inflammatory factors and endothelial injury factors in HUVECs stimulated by HCV. The two-independent-samples t test was used for comparison between two groups; an analysis of variance was used for comparison between multiple groups, and the LSD-t test was used for further comparison between two groups. ResultsCompared with the control group, the HCV group had no significant changes in the growth, apoptosis, and cell cycle of HUVECs (all P＞0.05). HCV stimulation inhibited the migration of HUVECs and enhanced their adhesion ability. Compared with the control group, the HCV group had significant increases in the mRNA and protein expression of the inflammatory factors interleukin-6 and interleukin-1β and the chemokines CXCL10 and monocyte chemotactic protein 1 (mRNA expression: t=-10.155, -12.048, -5.025, and -20.116, all P＜0.05; protein expression: F=2541.739, 4806.490, 477.608, and 501.38, all P＜0.001). HCV stimulation significantly upregulated the expression of the endothelial injury factors endothelin-1 and vascular endothelial growth factor and the adhesion molecules intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 in HUVECs (t=-4.530, -4.497, -7.692, and -7.449, all P＜0.05). ConclusionHCV can cause inflammatory changes and dysfunction in endothelial cells and thus affect the development of atherosclerosis.
ABSTRACT
Objective To explore the value of three-dimensional DSA (3D-DSA) in displaying the location of the origin of uterine artery.Methods A total of 90 female patients underwent uterine artery (UA) embolization were enrolled.The bilateral internal iliac artery catheterization were performed by 3D-DSA,then the images were reconstructed in every 5 degree interval to choose the optimum range of viewing angle.The origination and the degree of the origin artery and UA were calculated.The distance between the origin of UA and superior glutea artery which was identified as the locating point was measured.Results Bilateral and contralateral oblique position of ＞30°-60°were the optimal projection positions of UA.Totally 64.44％ (116/180) of UA originated from the anterior trunk of internal iliac artery,18.33％ (33/180) originated from the inferior gluteal trunk,9.44 ％ (17 / 180) originated from the internal pundenal artery,5.56 ％ (10 / 180) originated from internal iliac artery,and 2.22％ (4/180) originated from the superior gluteal artery;10.56％ (19/180) of the angle of the origin artery and UA were 0-30°,38.89％ (70/180) were ＞30°-60°,41.11％ (74/180) were ＞60°-90°,4.44％ (8/180) were＞90°-120°,2.78％ (5/180) were＞120°-150°,2.22％ (4/180) were＞150°-180°.Distance between the origin of UA and superior gluteal artery was 3.04-18.31 mm,average was (11.71±4.28)mm.Conclusion 3D-DSA can clearly display the origination,viewing angle and the distance away from superior gluteal artery.
ABSTRACT
Objective: To evaluate the efficiency and safety of endoscopic trans-fistula drainage (ETFD) for gastroesophageal anastomotic fistula with para-fistula abscess after esophagectomy. Methods: Among 456 esophageal cancer patients receiving esophagectomy between February 2012 and February 2017 in Sir Run Run Shaw Hospital, 15 cases were diagnosed as gastroesophageal anastomotic fistula with para-fistula abscess after surgery. Seven cases received ETFD treatment (ETFD group), and 8 cases received conventional treatment (control group). Recovery of inflammatory markers and fistula, length of hospital stay after esophagectomy and total medical expenses were compared between ETFD group and control group. Results: All patients recovered in ETFD group. Time of white cell count returning to normal and decline of C-reactive protein, time of fistula healing and length of hospital stay after esophagectomy in ETFD group were significantly shorter than those of control group (all PPConclusion: ETFD is effective and safe for gastroesophageal anastomotic fistula with para-fistula abscess after esophagectomy.
