Effect of multidisciplinary team model on prognosis of patients with traumatic amputation / 中华创伤杂志

Objective:To explore the effect of multidisciplinary team (MDT) model on prognosis of patients with traumatic amputation.Methods:A retrospective case-control study was conducted to analyze the clinical data of 54 patients with traumatic amputation admitted to Chongming Branch of Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from July 2014 to June 2019. There were 41 males and 13 females, aged 39-72 years with an average age of 52.7 years. A total of 29 patients treated using MDT model intervention were served as observation group, and 25 patients treated using routine responsibility system holistic nursing as control group. The self rating anxiety scale (SAS) score, self rating depression scale (SDS) score and improved Barthel index were compared between the two groups on the day of admission and at 2 weeks, 4 weeks and 8 weeks after operation.Results:There was no significant difference in SAS, SDS and improved Barthel index between the two groups on the day of admission ( P>0.05). At 2 weeks, 4 weeks and 8 weeks after operation, the SAS score in observation group was respectively (52.5±7.6)points, (48.3±7.1)points and (41.3±6.1)points, lower than those in control group [(58.0±12.0)points, (54.4±10.7)points and (50.4±9.3)points]; the SDS scores in observation group was respectively (52.6±8.8)points, (47.9±7.6)points, (43.8±5.7)points, lower than those in control group [(58.4±12.4)points, (53.2±10.9)points, (49.5±8.7)points]; the Barthel index score in observation group was respectively (57.2±8.9)points, (80.7±7.7)points, (94.7±3.9)points, higher than those in control group [(50.4±11.4)points, (70.9±9.5)points, (85.6±6.8)points] (all P<0.05). Conclusion:For patients with traumatic amputation, MDT model is conducive to reducing anxiety and depression of patients, can improve the quality of life, and is worthy of clinical application.

Comparison of characteristics of esophageal gastric varices in portal hypertension patients with and without spontaneous shunts / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To compare the characteristics of esophageal gastric varices in portal hypertension patients with and without spontaneous shunts.</p><p><b>METHODS</b>Clinical data of 118 patients with esophageal gastric varices undergoing portal vein computed tomographic angiography (CTA) and gastroscopy between January 2012 and August 2015 was retrospectively reviewed.</p><p><b>RESULTS</b>Portal vein CTA results showed that spleno-renal or gastro-renal shunts were detected in 24 out of 118 cases. The average portal vein diameters (PVD) of patients with and without spontaneous shunt were (12.48±2.79) mm and (13.58±3.46) mm, respectively (P>0.05). The average area of gastric veins in patients with spontaneous shunt was significantly larger than that of patients without shunt [294.00 (0.00~2400.00) mm2 vs. 26.00 (0.00~1620.00) mm2, respectively, (P<0.001]. Compared with patients without spontaneous shunt, the location of esophageal varices was lower and the degree was less serious in patients with spontaneous shunt (P<0.05). No matter with history of uppergastrointestinal bleeding, the average area of gastric veins in patients with spontaneous shunt was significantly larger than that of patients without shunt (P<0.05). For patients having no history of splenectomy, the average portal vein diameter (PVD) in those with spontaneous shunt was significantly smaller than that in those without shunt (P<0.05).</p><p><b>CONCLUSION</b>The portal vein diameter of patients without splenectomy and with spontaneous shunts is shorter and their esophageal varices are less serious; the gastric veins are large and wriggly in patients with spontaneous shunts.</p>

Biological characteristics and superiority of rat bone marrow mesenchymal stem cells isolated and cultured using whole bone marrow adherence method / 中国组织工程研究

BACKGROUND:Bone marrow mesenchymal stem cells are rare in vivo. It is important to purify, proliferate and differentiate bone marrow mesenchymal stem cells in vitro for further research. OBJECTIVE:To evaluate the biological characteristics, phenotype and multiple differentiation potential cultivation of bone marrow mesenchymal stem cells that are isolated, cultured and purified using the whole bone marrow adherence method. METHODS:Bone marrow mesenchymal stem cells were isolated, purified and cultured by the whole bone marrow adherence method. Morphological observation and flow cytometry determination of cellsurface markers were performed. Osteogenic and adipogenic differentiation of bone marrow mesenchymal stem cells was induced. RESULTS AND CONCLUSION:We successful y purified and proliferated bone marrow mesenchymal stem cells with high cellviability and differentiation ability. Fibroblast-like cells were harvested, expressing CD29 and CD90, but not CD45. Fol owing osteogenic and adipogenic induction, cells were positive for oil red O staining and alizarin red staining. The whole bone marrow adherence method is easy to operate, has little impact on cellviability, and can be used to harvest high-purification bone marrow mesenchymal stem cells with high cellviability and differentiation ability.
