Chinese Journal of Medical Education Research 2012;11(3):265-268
The humanities courses teaching has played an important role in the humanistic quality education in collegiate nursing education.Combining the teaching approaches of cultivating the nursing students' humanistic quality with the humanities courses teaching,it is a beneficial trial to construct the Trinitarian teaching model,in which the school,teachers and students should participate together in and out of class to develop the nursing students' humanistic knowledge,abilities and qualities.Of course,we also should pay much attention to some issues in implementing the teaching model,such as improving the students' qualifies step by step,the practicality of the teaching and the complementarities among diverse courses.
2.First aid and nursing experience of local anesthetic lidocaine poisoning
Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2017;24(4):437-438
Local anesthetic poisoning refers to that the concentration of the local agent enters into the body's blood circulation within a unit of time exceeding the body's ability to metabolize, resulting in the occurrence of a series of toxic clinical responses. Lidocaine is an amide narcotic drug, as a local surface infiltration anesthetic agent, its characteristics are as follows: its effect is rapid, dispersion wide spread, permeability strong, without significant irritation to tissues, but if the dosage is excessive, it can cause toxicity, therefore the dosage and method of application should be strictly controlled clinically. The experience of treatment and nursing care of lidocaine poisoning reaction was summarized.
4.Bone marrow mesenchymal stem cell transplantation for gastric precancerous lesions in a rat model
Chinese Journal of Tissue Engineering Research 2016;20(14):2073-2079
BACKGROUND:Precancerous lesions are a long-term development process in which many factors are involved. Bone marrow mesenchymal stem cel s can repair tissue injury. OBJECTIVE:To investigate the effect of bone marrow mesenchymal stem cel transplantation on gastric precancerous lesions in the rats. METHODS:Thirty-six Wistar rats were randomly divided into control group, model group and transplantation group. Animal models of gastric precancerous lesions were established in the model and transplantation groups. Rats in the transplantation group were given 1 mL of CM-dil-labeled bone marrow mesenchymal stem cel s (3×106 cel s) via the tail vein, once a week, total y three times. Rats in the model and control group were subjected to the tail vein injection of the same volume of normal saline. Then, rats were sacrificed 1 week after final injection, and pathohistological changes in rat gastric tissue sections were observed. The expression of vascular endothelial growth factor in the gastric mucosa and levels of serum cytokines were detected. RESULTS AND CONCLUSION:The severity of gastric mucosal injury in the transplantation group was lighter than that of the model group. The expression of vascular endothelial growth factor was significantly higher in the transplantation group compared with the model and control groups (P<0.05). The levels of serum interleukin-17 and interferon-γwere significantly higher in the model group than the transplantation group fol owed by the control group (both P<0.05). Therefore, bone marrow mesenchymal stem cel s can increase vascular permeability, reduce inflammation, block or ease the occurrence of precancerous lesions by up-regulating the expression of vascular endothelial growth factor in the gastric mucosa lesions and reducing the expression of interleukin-17 and interferon-γ.
5.Bone marrow mesenchymal stem cell transplantation protects against intestinal ischemia-reperfusion injury in rats
Chinese Journal of Tissue Engineering Research 2016;20(6):861-867
BACKGROUND:Bone marrow mesenchymal stem cels have good proliferation and paracrine functions, which have irreplaceable advantages in the treatment of intestinal diseases. OBJECTIVE:To explore the effects of bone marrow mesenchymal stem cel transplantation on intestinal ischemia-reperfusion injury in rats. METHODS:Forty-eight Sprague-Dawley rats were enroled to make animal models of ischemic reperfusion injury of the intestine, and then model rats were randomized into experimental and control groups. After modeling, 1 mL bone marrow mesenchymal stem cels or the same volume of normal saline were injected into the intestinal mucosa of rats in the two groups, respectively. At hours 0, 2, 6, 24, 72, 120 after injection, serum diamine oxidase,tumor necrosis factor α, and D-lactic acid levels were detected by ELISA method. At 24 hours after injection, rat intestinal tissues were taken and observed pathologicaly under light microscopy, and their close connections were observed under transmission electron microscope. ZO-1 protein levels were detected by immunohistochemistry method. RESULTS AND CONCLUSION:Compared with the control group, the serum diamine oxidase, tumor necrosis factor α, and D-lactic acid levels were significantly lower in the experimental group at hours 6 and 24 after injection (P < 0.05). Intestinal necrosis, vilous edema, intestinal congestion and inflammatory cel infiltration in the experimental group were milder than those in the control group. In addition, the ZO-1 protein expression in the experimental group was higher than that in the control group. Experimental results show that bone marrow mesenchymal stem cel transplantation into the intestinal mucosa can improve the intestinal mucosal permeability in rats with intestinal ischemia-reperfusion injury.
